技术领域Technical field

本发明涉及灯带技术领域，尤其涉及一种智能灯带检测方法、电路、装置及智能灯带。The present invention relates to the technical field of light strips, and in particular to an intelligent light strip detection method, circuit, device and smart light strip.

背景技术Background technique

智能灯带作为装饰行业常用的装饰材料，被普遍应用在家庭吊顶、工装外墙装饰造型。发光模组具有工作电压低、工作电流小、抗冲击抗震性能好、可靠性高以及寿命长等优点，在室内室外照明以及灯光装饰等领域中得到广泛应用。现如今，各式各样的装设景观灯就是通过多个LED光源连接组成，其中包含智能灯带。As a commonly used decorative material in the decoration industry, smart light strips are widely used in home ceilings and tooling exterior wall decoration styles. Light-emitting modules have the advantages of low operating voltage, low operating current, good impact and seismic resistance, high reliability and long life, and are widely used in indoor and outdoor lighting and lighting decoration and other fields. Nowadays, various installed landscape lights are composed of multiple LED light sources connected, including smart light strips.

由于并联发光模组组成的灯带具有各发光模组可单独控制，且亮度可以保持一致且稳定的发光模组，因此常用的发光模组带通常由多个在电路上并联的发光模组组成。在发光模组带驱动过程中，需要根据智能灯带中具体发光模组的数目确定具体的驱动电参数，避免电流过大或过小对发光模组造成影响。此外，由于智能灯带中的发光模组通常为间隔相同的距离设置，在智能灯带驱动过程中确定整个智能灯带的长度便十分重要，而在部分应用场合内难以的确定智能灯带长度。Since the light strips composed of parallel light-emitting modules can be individually controlled and the brightness can be kept consistent and stable, commonly used light-emitting module strips are usually composed of multiple light-emitting modules connected in parallel on the circuit. . During the driving process of the light-emitting module strip, it is necessary to determine the specific driving electrical parameters according to the number of specific light-emitting modules in the smart light strip to avoid the impact of too large or too small current on the light-emitting modules. In addition, since the light-emitting modules in smart light strips are usually set at the same distance apart, it is very important to determine the length of the entire smart light strip during the driving process of the smart light strip. However, it is difficult to determine the length of the smart light strip in some applications. .

应理解的是，当前市场上的智能灯带，因智能灯带中不同的发光模组以串联电路或并联电路的方式接入电路的不同，而具有多种点亮方式，例如，发光模组以串联电路连接拼接成智能灯带时，智能灯带内的所有发光模组均在同一时间内点亮；发光模组以并联电路连接拼接成智能灯带时，各个发光模组可以依次逐个点亮或部分发光模组同时点亮等。It should be understood that the smart light strips currently on the market have a variety of lighting methods due to the different light-emitting modules in the smart light strips being connected to the circuit in a series circuit or a parallel circuit. For example, the light-emitting modules When the light-emitting modules are connected in series circuits to form a smart light strip, all the light-emitting modules in the smart light strip light up at the same time; when the light-emitting modules are connected in parallel circuits to form a smart light strip, each light-emitting module can be lit one by one in turn. or part of the light-emitting modules light up at the same time, etc.

参照图1，图1为本发明智能灯带检测方法的第一实施例的流程示意图。基于图1提出本发明智能灯带检测方法的第一实施例。Referring to Figure 1, Figure 1 is a schematic flow chart of the first embodiment of the intelligent light strip detection method of the present invention. Based on Figure 1, a first embodiment of the intelligent light strip detection method of the present invention is proposed.

在本实施例中，所述智能灯带包括多个在长度方向上拼接的发光模组，所述多个拼接的发光模组以并联的方式接入电路，所述发光模组包括驱动芯片、至少一个发光单元，所述驱动芯片用于驱动至少一个所述发光单元，所述智能灯带检测方法包括：In this embodiment, the smart light strip includes a plurality of light-emitting modules spliced in the length direction. The plurality of spliced light-emitting modules are connected to the circuit in a parallel manner. The light-emitting module includes a driver chip, At least one light-emitting unit, the driving chip is used to drive at least one of the light-emitting unit, and the intelligent light strip detection method includes:

步骤S10：检测智能灯带内各发光模组逐个点亮过程中智能灯带中的电参数信号。Step S10: Detect the electrical parameter signals in the smart light strip during the lighting of each light-emitting module in the smart light strip one by one.

本发明实施例中，各发光模组以并联的方式接入智能灯带电路中。本发明中的发光模组可以依次逐个点亮的方式实现类似于跑马灯的显示方式，控制器发送点亮信号，在前一个发光模组点亮之后，检测记录该前一发光模组点亮时，智能灯带电路中的电参数变化。间隔一个短暂的周期之后，下一个发光模组点亮，前一个发光模组熄灭，检测记录当前点亮中的发光模组所对应的智能灯带电路中的电参数变化。长度方向是指智能灯带的电源端指向灯带末端的方向。本实施例中各发光模组虽然以并联的方式接入，但是在智能灯带内各个发光模组在长度方向上依次排列。In the embodiment of the present invention, each light-emitting module is connected to the smart light strip circuit in a parallel manner. The light-emitting modules in the present invention can be lit one by one in order to achieve a display similar to a marquee. The controller sends a lighting signal, and after the previous light-emitting module lights up, it detects and records that the previous light-emitting module is lit. time, the electrical parameters in the smart light strip circuit change. After a short period, the next light-emitting module lights up and the previous light-emitting module goes out. The changes in electrical parameters in the smart light strip circuit corresponding to the currently lit light-emitting module are detected and recorded. The length direction refers to the direction in which the power end of the smart light strip points to the end of the light strip. In this embodiment, although the light-emitting modules are connected in parallel, the light-emitting modules are arranged sequentially in the length direction in the smart light strip.

本发明的一种可能的实施例中，一个智能灯带内的发光模组的类型规格相同，即智能灯带中各发光模组的电参数均相同，使智能灯带中各发光模组的亮度相同。为了保证智能灯带整体亮度的均匀性，将各发光模组拼接起来形成智能灯带的过程中，各个发光模组之间间隔保持相同的距离设置。本发明实施例中，沿智能灯带长度方向上拼接的各发光模组以并联电路的方式接入智能灯带的电路中。因此智能灯带的长度信息与智能灯带中的发光模组数目密切相关，在智能灯带驱动过程中，需要确定智能灯带中发光模组的具体数目或长度，从而设定合适的驱动电压对智能灯带进行驱动。在不确定灯带长度的情况下，智能灯带的驱动电压过大，会导致智能灯带内的当前点亮发光模组过亮，甚至在驱动的瞬间导致发光模组烧损；智能灯带的驱动电压过小，会直接导致智能灯带中的电流较低，当前电流的发光模组亮度不足。In a possible embodiment of the present invention, the types and specifications of the light-emitting modules in a smart light strip are the same, that is, the electrical parameters of each light-emitting module in the smart light strip are the same, so that the electrical parameters of each light-emitting module in the smart light strip are The brightness is the same. In order to ensure the uniformity of the overall brightness of the smart light strip, when the light-emitting modules are spliced together to form the smart light strip, the distance between each light-emitting module should be maintained at the same distance. In the embodiment of the present invention, the light-emitting modules spliced along the length direction of the smart light strip are connected to the circuit of the smart light strip in a parallel circuit. Therefore, the length information of the smart light strip is closely related to the number of light-emitting modules in the smart light strip. During the driving process of the smart light strip, it is necessary to determine the specific number or length of the light-emitting modules in the smart light strip, so as to set the appropriate driving voltage. Drive smart light strips. When the length of the light strip is uncertain, the smart If the driving voltage of the smart light strip is too high, it will cause the currently lit light-emitting module in the smart light strip to be too bright, and even cause the light-emitting module to burn out at the moment of driving; if the driving voltage of the smart light strip is too small, it will directly cause the smart light strip to burn out. The current in the light strip is low, and the brightness of the light-emitting module with the current current is insufficient.

本发明又一种可能的实施例中，所述智能灯带中，只有部分发光模组的类型规格部分保持一致。例如，智能灯带由发光模组1和发光模组2沿长度方向拼接而成。其中，发光模组1具有6个串联的发光单元，发光模组2具有7个串联的发光单元。In another possible embodiment of the present invention, in the smart light strip, only some of the light-emitting modules have the same type and specifications. For example, a smart light strip is composed of a light-emitting module 1 and a light-emitting module 2 spliced along the length direction. Among them, the light-emitting module 1 has 6 light-emitting units connected in series, and the light-emitting module 2 has 7 light-emitting units connected in series.

需要说明的是，在本实施例中的执行主体可以是智能灯带检测装置，该灯带检测装置包括电参数检测单元和运算控制单元。电参数检测单元可以对智能灯带中的电参数信号进行采集，运算控制单元可以根据采集到的电参数信号确定智能灯带的当前状态。该电参数信号可以为智能灯带在点亮过程中智能灯带中的电流信号或电压信号。It should be noted that the execution subject in this embodiment may be an intelligent light strip detection device, which includes an electrical parameter detection unit and an arithmetic control unit. The electrical parameter detection unit can collect electrical parameter signals in the smart light strip, and the computing control unit can determine the current status of the smart light strip based on the collected electrical parameter signals. The electrical parameter signal may be a current signal or a voltage signal in the smart light strip during the lighting process of the smart light strip.

步骤S20：记录所述电参数信号的变化信息。Step S20: Record the change information of the electrical parameter signal.

应理解的是，在整个智能灯带点亮过程中，随着灯带中的各个发光模组不断的被点亮，由于各发光模组存在点亮上的事件间隔，从而导致整个智能灯带内的电参数不断的发生变化。其中，变化信息可以是智能灯带内的发光模组逐个点亮过程中电参数不断变化的信息。在智能灯带驱动过程中，每点亮一个发光模组，智能灯带内的电压或电流均会发生一次变化，并且每次变化的幅值与发光模组的电阻值相关。所述变化信息可以是电参数的幅值变化信息或电参数的次数变化信息。It should be understood that during the entire smart light strip lighting process, as each light-emitting module in the light strip is continuously lit, due to the event interval between lighting events of each light-emitting module, the entire smart light strip will The electrical parameters inside are constantly changing. Among them, the change information can be information about the continuous changes in electrical parameters during the lighting process of the light-emitting modules in the smart light strip one by one. During the driving process of the smart light strip, every time a light-emitting module is lit, the voltage or current in the smart light strip will change, and the amplitude of each change is related to the resistance value of the light-emitting module. The change information may be amplitude change information of the electrical parameter or frequency change information of the electrical parameter.

本发明实施例中，所述发光模组可以包括两个及两个以上串联的发光单元。一种可能的实施方式中，本发明中的发光模组均由同一数量或不同数量同一类型规格的发光单元所串联组成，所述发光单元可以为LED发光单元，同时，每一个发光模组中均具有驱动控制芯片。In embodiments of the present invention, the light-emitting module may include two or more light-emitting units connected in series. In a possible implementation, the light-emitting modules in the present invention are composed of the same number or different numbers of light-emitting units of the same type and specifications connected in series. The light-emitting units can be LED light-emitting units. At the same time, in each light-emitting module All have drive control chips.

由于智能灯带内的各发光模组发光单元的型号、电阻值、功率等参数均相同，因此，在不断逐个点亮发光模组的过程中，智能灯带中的电参数信号变化遵循一定的规律进行变化。Since the light-emitting units of each light-emitting module in the smart light strip have the same model, resistance value, power and other parameters, during the process of lighting up the light-emitting modules one by one, the changes in the electrical parameter signals in the smart light strip follow a certain pattern. The rules change.

步骤S30：根据所述变化信息确定所述智能灯带的灯带长度。Step S30: Determine the length of the smart light strip according to the change information.

应理解的是，在确定整个智能灯带点亮过程中的电参数信号的变化信息时，可以直接根据变化信息确定智能灯带的长度。在智能灯带点亮过程中，灯带内接入的总电阻不断的发生变化，根据每次点亮发光模组的总电阻，确定该发光模组接入智能灯带中的长度，从而确定智能灯带中，各发光模组接入智能灯带的长度。It should be understood that when determining the change information of the electrical parameter signal during the entire lighting process of the smart light strip, the length of the smart light strip can be determined directly based on the change information. During the lighting process of the smart light strip, the total resistance connected to the light strip continues to change. According to the total resistance of the light-emitting module each time it is lit, the length of the light-emitting module connected to the smart light strip is determined, thereby determining In the smart light strip, the length of each light-emitting module connected to the smart light strip.

由于各发光模组拼接起来时的间隔是保持一致的，并且各发光模组内的发光单元之间的间隔同样保持一致。因此可以在确定智能灯带中内接入的总电阻时，从而可以根据发光模组中接入的总电阻确定各发光模组中预先设定的单位电阻值的数目即各发光模组中包含发光单元的数目，根据发光单元的数目确定各发光模组的长度。又或者在一种可能的设计中，建立发光模组接入灯带电路的电阻值与发光模组长度的映射关系，在获取发光模组点亮时接入灯带电路中的电阻值，从而可以确定发光模组的长度。然后，可以根据各发光模组的长度和拼接间隔确定智能灯带的总长度。Because the intervals between the light-emitting modules are consistent when they are spliced together, and the intervals between the light-emitting units in each light-emitting module are also consistent. Therefore, when determining the total resistance connected in the smart light strip, the number of preset unit resistance values in each light-emitting module can be determined based on the total resistance connected in the light-emitting module, that is, each light-emitting module contains The number of light-emitting units determines the length of each light-emitting module according to the number of light-emitting units. Or in a possible design, establish a mapping relationship between the resistance value of the light-emitting module connected to the light strip circuit and the length of the light-emitting module, and obtain the resistance value of the light-emitting module connected to the light strip circuit when it is lit, thereby The length of the lighting module can be determined. Then, the total length of the smart light strip can be determined based on the length and splicing interval of each light-emitting module.

此外，由于智能灯带中的发光模组依次点亮的过程中均会引起整个智能灯带内的电参数信号发生一次变化，因此，在本实施例中，还可以直接根据电参数信号的变化次数直接确定接入智能灯带内的不断接入的发光模组数目，然后根据智能灯带内具体接入的发光模组数目以及相邻发光模组之间预先设定的单位距离确定整个智能灯带的长度信息。In addition, since the lighting modules in the smart light strip are sequentially lit, the electrical parameter signal in the entire smart light strip will change once. Therefore, in this embodiment, it is also possible to directly adjust the electrical parameter signal according to the change in the electrical parameter signal. The number of times directly determines the number of continuously connected luminous modules connected to the smart light strip, and then based on the specific number of luminous modules connected to the smart light strip. The number of modules and the preset unit distance between adjacent light-emitting modules determine the length information of the entire smart light strip.

本实施例提供了一种智能灯带检测方法，该智能灯带检测方法通过检测智能灯带内各发光模组逐个点亮过程中智能灯带中的电参数信号；记录所述电参数信号的变化信息；根据所述变化信息确定所述智能灯带的灯带长度。在本实施例中，通过在智能灯带点亮过程中对电流信号的采集确定智能灯带中电参数信号的变化信息，并利用智能灯带中电参数信号的变化信息确定智能灯带的长度信息。This embodiment provides a smart light strip detection method. The smart light strip detection method detects the electrical parameter signals in the smart light strip during the lighting of each light-emitting module in the smart light strip one by one; records the electrical parameter signals. Change information; determine the length of the smart light strip based on the change information. In this embodiment, the change information of the electrical parameter signal in the smart light strip is determined by collecting the current signal during the lighting process of the smart light strip, and the length of the smart light strip is determined using the change information of the electrical parameter signal in the smart light strip. information.

参照图2，图2为本发明智能灯带检测方法的第二实施例的流程示意图。基于上述智能灯带检测方法的第一实施例，提出本发明智能灯带检测方法的第二实施例。Referring to Figure 2, Figure 2 is a schematic flow chart of a second embodiment of a smart light strip detection method of the present invention. Based on the first embodiment of the above-mentioned smart light strip detection method, a second embodiment of the smart light strip detection method of the present invention is proposed.

在本实施例中，所述步骤S30之后，还包括：In this embodiment, after step S30, it also includes:

步骤S40：在所述变化信息为幅值变化信息时，获取最后一次的电参数变化值智能灯带。Step S40: When the change information is amplitude change information, obtain the last electrical parameter change value of the smart light strip.

步骤S50：根据所述最后一次的电参数变化值是否遵循发光模组点亮导致的幅值变化规律确定所述智能灯带的末端是否存在末端控制模块。Step S50: Determine whether there is an end control module at the end of the smart light strip based on whether the last electrical parameter change value follows the amplitude change rule caused by lighting of the light-emitting module.

应理解的是，由于发光模组的发光单元的电参数均相同，且发光模组均由驱动芯片加上若干个发光单元组成，因此，发光模组接入智能灯带的电阻值与其所含有的所述若干个发光单元线性正比的关系，在逐个点亮发光模组过程中智能灯带内的电阻变化遵循一定的规律，此时智能灯带内的电流或电压的变化也具有一定的规律性，该规律为发光模组点亮导致的幅值变化规律。例如发光模组内每个发光单元的电阻均为10欧姆，在不考虑其他器件的影响的情况下，通过10V的标准电压对灯带进行驱动，在第一个发光模组点亮时，智能灯带内的电阻为10欧姆，电流为1安；在第二个发光模组点亮时，智能灯带内的电阻为20欧姆，电流为0.5安；在第三个发光模组点亮时，智能灯带内的电阻为30欧姆，电流为0.33安；以此类推可知发光模组点亮过程中的电流变化规律。It should be understood that since the electrical parameters of the light-emitting units of the light-emitting module are the same, and the light-emitting modules are composed of a driver chip plus several light-emitting units, the resistance value of the light-emitting module connected to the smart light strip is the same as the resistance value contained in the light-emitting module. The linear proportional relationship between the several light-emitting units is linearly proportional. During the process of lighting up the light-emitting modules one by one, the resistance changes in the smart light strip follow certain rules. At this time, the changes in current or voltage in the smart light strip also have certain rules. Nature, this law is the amplitude change law caused by the lighting of the light-emitting module. For example, the resistance of each light-emitting unit in the light-emitting module is 10 ohms. Without considering the influence of other devices, the light strip is driven by a standard voltage of 10V. When the first light-emitting module lights up, the intelligent The resistance in the smart light strip is 10 ohms and the current is 1 A; when the second light-emitting module is lit, the resistance in the smart light strip is 20 ohms and the current is 0.5 A; when the third light-emitting module is lit , the resistance in the smart light strip is 30 ohms, and the current is 0.33 A; by analogy, we can know the current change pattern during the lighting process of the light-emitting module.

需要说明的是，最后一次的电参数变化值是指智能灯带点亮全过程中，灯带内的电参数的变化幅值。由于末端控制模块与发光模组具有很大的差异性，末端控制模块对应的电阻值与单个发光模组对应的电阻值差异较大。在存在末端控制模块的情况下，该电参数信号最后一次发生变化时，变化的幅值并不符合发光模组点亮过程中的变化规律。而在智能灯带末端并不存在末端控制模块时，最后一次的电参数变化是由于最后一个发光模组点亮引起的变化，该过程中的电参数变化值符合发光模组点亮过程中的电变化规律。因此，在确定是否智能灯带的末端是否存在末端控制模块时，可以判断智能灯带内最后一次的电参数变化值是否符合发光模组点亮过程中的电变化规律即可确定智能灯带末端是否存在模块控制模块。It should be noted that the last electrical parameter change value refers to the change amplitude of the electrical parameters in the smart light strip during the entire lighting process of the smart light strip. Since the end control module and the light-emitting module are very different, the resistance value corresponding to the end control module is significantly different from the resistance value corresponding to a single light-emitting module. In the case where there is an end control module, when the electrical parameter signal changes for the last time, the amplitude of the change does not conform to the change pattern during the lighting process of the light-emitting module. When there is no end control module at the end of the smart light strip, the last electrical parameter change is caused by the lighting of the last light-emitting module. The electrical parameter change value in this process is consistent with the lighting process of the light-emitting module. The law of electrical changes. Therefore, when determining whether there is an end control module at the end of the smart light strip, it can be determined whether the last electrical parameter change value in the smart light strip conforms to the electrical change pattern during the lighting process of the light-emitting module to determine the end of the smart light strip. Whether the module control module exists.

当然，如果单纯只是对智能灯带进行点亮，智能灯带在最后一个发光模组点亮之后，整个智能灯带内的电参数信号并不会继续发生变化。而在智能灯带的末端接入末端控制模块的情况下，末端控制模块可以对智能灯带内的电参数信号进行调节。此时，智能灯带的控制器还可以通过检测电参数信号确定智能灯带的末端是否存在末端控制模块。Of course, if the smart light strip is simply lit, the electrical parameter signals in the entire smart light strip will not continue to change after the last light-emitting module of the smart light strip is lit. When the end of the smart light strip is connected to the end control module, the end control module can adjust the electrical parameter signals in the smart light strip. At this time, the controller of the smart light strip can also determine whether there is an end control module at the end of the smart light strip by detecting the electrical parameter signal.

在本实施例中，在智能灯带完全点亮之后控制器还可以对智能灯带中的电参数信号是否发生变化对末端控制模块进行检测。在智能灯带完全点亮之后，可以对末端控制模块内接入智能灯带的电阻进行调节，此时智能灯带内的电参数会根据末端控制模块接入的电阻变化而发生变化，所述控制器还可以根据接收到的所述电参数信号是否发生变化确定所述智能灯带尾端是否存在所述末端控制模块。例如在智能灯带驱动完成之后，在末端控制模块内的可变电阻的阻值发生变化时，智能灯带内的电流会发生相应的变化，控制模块在接收到的电参数信号发生变化的情况下，即可认定存在末端控制模块。In this embodiment, after the smart light strip is completely lit, the controller can also detect whether the electrical parameter signal in the smart light strip changes to the end control module. After the smart light strip is fully lit, the resistance of the smart light strip connected to the end control module can be adjusted. At this time, the electrical parameters in the smart light strip will change according to the change of the resistance connected to the end control module. The controller can also determine whether the received electrical parameter signal changes. Whether there is the end control module at the end of the smart light strip. For example, after the smart light strip is driven, when the resistance of the variable resistor in the end control module changes, the current in the smart light strip will change accordingly, and the electrical parameter signal received by the control module changes. , it can be determined that there is an end control module.

步骤S60：在所述智能灯带的末端存在末端控制模块时，检测所述智能灯带中是否存在载波信号；Step S60: When there is an end control module at the end of the smart light strip, detect whether there is a carrier signal in the smart light strip;

步骤S70：在检测到所述载波信号时，对所述载波信号进行解析获取所述末端控制模块发送的传输信息。Step S70: When the carrier signal is detected, analyze the carrier signal to obtain the transmission information sent by the terminal control module.

此外，在本实施例中，还可以通过末端控制模块确定智能灯带的长度信息。在智能灯带内的发光模组点亮完成之后，可以采集末端控制模块内接入的电阻两端的电压值，然后结合接入电阻的阻值确定整个智能灯带内的电流值。在电流值确定的情况下，可以结合驱动电压得到智能灯带内的总阻值，此时利用智能灯带内的总阻值减去采样电阻的阻值以及可变电阻的阻值便可以计算出智能灯带中的发光模组的总阻值。In addition, in this embodiment, the length information of the smart light strip can also be determined through the end control module. After the light-emitting module in the smart light strip is lit, the voltage value at both ends of the resistor connected in the end control module can be collected, and then combined with the resistance value of the connected resistor to determine the current value in the entire smart light strip. When the current value is determined, the total resistance value in the smart light strip can be obtained by combining the driving voltage. At this time, the total resistance value in the smart light strip minus the resistance value of the sampling resistor and the resistance value of the variable resistor can be calculated. Find the total resistance of the light-emitting module in the smart light strip.

一种可能的设计中，根据发光模组的电阻值与发光单元数量之间的映射关系，在获悉各发光模组并联接入智能灯带的总电阻时，可以预估该各发光模组的各自的构成情况以及发光模组的数量。一个发光模组内可能包括多个发光单元，该发光模组点亮时，内部的每一个发光单元均点亮，此时可以根据该发光模组导致的电参数幅值变化信息确定各发光模组内的发光单元数目。例如一个发光模组内仅包括一个发光单元、另一个发光模组内包括两个发光单元，此时在第一个发光模组点亮时，电参数信号的幅值变化由一个发光单元导致；而第二个发光模组点亮时，电参数信号的幅值变化有两个发光单元导致，可以根据具体的幅值变化程度确定当前点亮发光模组内的发光单元具体数目。此外，在智能灯带点亮过程中，每次存在发光模组点亮时，均会引起电参数信号发生一次变化，控制器也可以根据电参数信号变化的总次数确定发光模组的数量。在不计算智能灯带前端和后端连接的其他模块的情况下，该电参数变化的次数信息便是发光模组的数量。In one possible design, according to the mapping relationship between the resistance value of the light-emitting module and the number of light-emitting units, when the total resistance of each light-emitting module connected in parallel to the smart light strip is known, the resistance of each light-emitting module can be estimated. Their respective compositions and the number of light-emitting modules. A light-emitting module may include multiple light-emitting units. When the light-emitting module is lit, each light-emitting unit inside is lit. At this time, each light-emitting module can be determined based on the electrical parameter amplitude change information caused by the light-emitting module. The number of light-emitting units in the group. For example, one light-emitting module only includes one light-emitting unit, and another light-emitting module includes two light-emitting units. At this time, when the first light-emitting module is lit, the amplitude change of the electrical parameter signal is caused by one light-emitting unit; When the second light-emitting module is lit, the amplitude change of the electrical parameter signal is caused by two light-emitting units. The specific number of light-emitting units in the currently lit light-emitting module can be determined based on the specific amplitude change degree. In addition, during the lighting process of the smart light strip, every time a light-emitting module lights up, it will cause a change in the electrical parameter signal. The controller can also determine the number of light-emitting modules based on the total number of changes in the electrical parameter signal. Without counting other modules connected to the front and back ends of the smart light strip, the information on the number of changes in the electrical parameters is the number of light-emitting modules.

在具体调节过程中，末端控制模块内的调节芯片可以根据所述待传输信息调节所述可变电阻的阻值大小，在所述智能灯带内形成预设电流值的电流载波；当然，可调节芯片还可以根据所述待传输信息调节所述可变电阻的阻值变化频率，在所述智能灯带内形成预设频率的电流载波；调节芯片还可以在调节可变电阻R2阻值的同时伴随一定的频率调节。通过阻值与频率结合的方式可以传输的待传输信息的种类更加丰富。所述待传输信息包括：末端控制模块内描述数据属性的元数据信息、型号信息、功能信息以及版本信息，当然还可以包括一些给末端控制模块的控制命令，改变末端控制模块的固有状态。During the specific adjustment process, the adjustment chip in the terminal control module can adjust the resistance of the variable resistor according to the information to be transmitted, and form a current carrier with a preset current value in the smart light strip; of course, it can The adjustment chip can also adjust the resistance change frequency of the variable resistor according to the information to be transmitted, and form a current carrier of a preset frequency in the smart light strip; the adjustment chip can also adjust the resistance of the variable resistor R2 when At the same time, it is accompanied by a certain frequency adjustment. The types of information to be transmitted that can be transmitted through the combination of resistance value and frequency are more abundant. The information to be transmitted includes: metadata information describing data attributes in the terminal control module, model information, function information and version information. Of course, it may also include some control commands to the terminal control module to change the inherent state of the terminal control module.

在本实施例中，通过在智能灯带的尾端设置末端控制模块实现智能灯带的首端与尾端之间的双向通信可以大大节省成本。在保证通用性的前提下，利用很低的成本实现了双向通信，增加智能灯带的功能提高了拓展性。In this embodiment, by arranging an end control module at the tail end of the smart light strip to realize two-way communication between the head end and the tail end of the smart light strip, costs can be greatly saved. On the premise of ensuring versatility, two-way communication is achieved at a very low cost, and the function of smart light strips is added to improve scalability.

参照图3，图3为本发明智能灯带检测电路的第一实施例的电路结构示意图。基于图1提出本发明智能灯带检测电路的第一实施例。Referring to Figure 3, Figure 3 is a schematic circuit structure diagram of the first embodiment of the intelligent light strip detection circuit of the present invention. Based on Figure 1, a first embodiment of a smart light strip detection circuit of the present invention is proposed.

如图1所示，在本实施例中，所述智能灯带检测电路包括：电参数检测模块10以及控制器20；As shown in Figure 1, in this embodiment, the smart light strip detection circuit includes: an electrical parameter detection module 10 and a controller 20;

其中，所述电参数检测模块10分别与智能灯带以及所述控制器20连接。Wherein, the electrical parameter detection module 10 is connected to the smart light strip and the controller 20 respectively.

需要说明的是，在智能灯带驱动过程中，驱动模块可以与电源连接并将电源电压转换为智能灯带所需要的电压。电参数检测模块10是用于智能灯带中的电参数信号进行采集的模块。电参数检测模块10可以设置在灯带内的电流检测器件或并联设置在灯带两侧的电阻采样器件。在智能灯带内发光模组的点亮过程中，智能灯带内的电流或电压会不断的发生变化，每点亮一个发光模组智能灯带内的电流或电压变化发生一次变化。控制器20可以根据智能灯带内的电参数信号的变化情况确定智能灯带内连接的发光模组的数目。由于智能灯带中各发光模组之间间隔的距离相同，所以在各发光模组点亮时的电流值一样的前提下，确定发光模组的数目后，可以直接根据发光模组的数目计算出灯带的具体长度。控制器20可以根据智能灯带的长度信息对驱动模块输出的电压进行调节，以使智能灯带中的发光模组均处于最佳工作状态。It should be noted that during the smart light strip driving process, the driving module can be connected to the power supply and change the power supply voltage to Convert to the voltage required for smart light strips. The electrical parameter detection module 10 is a module used for collecting electrical parameter signals in the smart light strip. The electrical parameter detection module 10 can be a current detection device arranged in the lamp strip or a resistance sampling device arranged in parallel on both sides of the lamp strip. During the lighting process of the light-emitting modules in the smart light strip, the current or voltage in the smart light strip will continue to change. Each time a light-emitting module is lit, the current or voltage in the smart light strip will change. The controller 20 can determine the number of light-emitting modules connected in the smart light strip according to changes in the electrical parameter signals in the smart light strip. Since the distance between each light-emitting module in the smart light strip is the same, under the premise that the current value of each light-emitting module when lighting is the same, after determining the number of light-emitting modules, it can be calculated directly based on the number of light-emitting modules. The specific length of the light strip. The controller 20 can adjust the voltage output by the driving module according to the length information of the smart light strip, so that the light-emitting modules in the smart light strip are in optimal working condition.

在具体实施中，驱动模块可以输出一定的电压或电流至智能灯带对智能灯带进行驱动，所述电参数检测模块10在驱动模块输出电压之后，实时采集所述智能灯带点亮过程中的电参数信号，并将所述电参数信号发送至所述控制器20直至智能灯带内的电参数信号不再发生变化；所述控制器20在接收到所述电参数信号时，对每次智能灯带内电流或电压发生变化均进行记录，得到电参数信号的电流或电压的变化信息；然后根据所述电流或电压的变化信息确定智能灯带中所包括发光模组的数目，最后根据发光模组的数目以及各发光模组之间的间隔距离计算所述智能灯带的长度信息。In a specific implementation, the driving module can output a certain voltage or current to the smart light strip to drive the smart light strip. After the driving module outputs the voltage, the electrical parameter detection module 10 collects real-time data during the lighting process of the smart light strip. electrical parameter signal, and sends the electrical parameter signal to the controller 20 until the electrical parameter signal in the smart light strip no longer changes; when receiving the electrical parameter signal, the controller 20 All current or voltage changes in the smart light strip are recorded to obtain the current or voltage change information of the electrical parameter signal; then the number of light-emitting modules included in the smart light strip is determined based on the current or voltage change information, and finally The length information of the smart light strip is calculated according to the number of light-emitting modules and the spacing distance between the light-emitting modules.

其中，电参数信号为整个智能灯带驱动全过程内的电流值或电压值。Among them, the electrical parameter signal is the current value or voltage value during the entire smart light strip driving process.

在本实施例中该智能灯带检测电路包括：电参数检测模块以及控制器；所述电参数检测模块分别与所述智能灯带以及所述控制器连接；所述电参数检测模块，用于检测所述智能灯带点亮过程中的电参数信号，并将所述电参数信号发送至所述控制器；所述控制器，用于在接收到所述电参数信号时，记录所述电参数信号的变化信息；根据所述变化信息确定所述智能灯带的长度信息。在本实施例中，通过在智能灯带点亮过程中对电流信号的采集确定智能灯带中电参数信号的变化信息，并利用智能灯带中电参数信号的变化信息确定智能灯带的长度信息。In this embodiment, the smart light strip detection circuit includes: an electrical parameter detection module and a controller; the electrical parameter detection module is connected to the smart light strip and the controller respectively; the electrical parameter detection module is used to Detect the electrical parameter signal during the lighting process of the smart light strip, and send the electrical parameter signal to the controller; the controller is used to record the electrical parameter signal when receiving the electrical parameter signal. Change information of the parameter signal; determine the length information of the smart light strip based on the change information. In this embodiment, the change information of the electrical parameter signal in the smart light strip is determined by collecting the current signal during the lighting process of the smart light strip, and the length of the smart light strip is determined using the change information of the electrical parameter signal in the smart light strip. information.

参照图4，图4为本发明智能灯带检测电路的第二实施例的第一种电路结构示意图。Referring to Figure 4, Figure 4 is a schematic diagram of a first circuit structure of a second embodiment of a smart light strip detection circuit of the present invention.

在本实施例中，所述电参数检测模块包括：与各发光模组串联设置的采样电阻R1；In this embodiment, the electrical parameter detection module includes: a sampling resistor R1 arranged in series with each light-emitting module;

其中，所述采样电阻R1的一端与驱动模块连接，另一端与智能灯带中串联设置的发光模组连接，所述采样电阻R1的两端还分别与控制器20的采样引脚连接。One end of the sampling resistor R1 is connected to the driving module, and the other end is connected to the light-emitting module arranged in series in the smart light strip. The two ends of the sampling resistor R1 are also connected to the sampling pins of the controller 20 respectively.

应理解的是，在本实施例中通过设置采样电阻R1的方式对智能灯带中的电流值进行采集。采样电阻R1与各个发光模组串联设置，由于发光模组具有一定的电阻性，因此每个发光模组在点亮过程中均会导致智能灯带中的电阻发生变化，在驱动模块输出电压恒定的情况下，智能灯带中的电阻发生变化会直接导致智能灯带中的电流发生变化。例如在第一个发光模组D1点亮时，智能灯带中的总阻值为采样电阻R1和第一个发光模组D1的阻值；在第二个发光模组D2点亮时，智能灯带中的总阻值为采样电阻R1、第二个发光模组D2的阻值；依次类推，每次有发光模组点亮，智能灯带中的总阻值均会因发光模组的阻值不同而发生变化。It should be understood that in this embodiment, the current value in the smart light strip is collected by setting the sampling resistor R1. The sampling resistor R1 is set in series with each light-emitting module. Since the light-emitting module has a certain resistance, each light-emitting module will cause the resistance in the smart light strip to change during the lighting process. When the driving module output voltage is constant In this case, changes in the resistance in the smart light strip will directly lead to changes in the current in the smart light strip. For example, when the first light-emitting module D1 lights up, the total resistance in the smart light strip is the resistance of the sampling resistor R1 and the first light-emitting module D1; when the second light-emitting module D2 lights up, the smart light strip The total resistance in the light strip is the resistance of the sampling resistor R1 and the second light-emitting module D2. By analogy, every time a light-emitting module lights up, the total resistance in the smart light strip will be affected by the resistance of the light-emitting module. The resistance value changes.

在具体实施中，在智能灯带的驱动过程中，控制器20可以通过相应的采样引脚对采样电阻R1两端的电压值进行实时采集，从而根据采集到的电压值和采样电阻的电阻值得到智能灯带中的电参数信号。In a specific implementation, during the driving process of the smart light strip, the controller 20 can collect the voltage value at both ends of the sampling resistor R1 in real time through the corresponding sampling pin, so as to calculate the voltage value at both ends of the sampling resistor R1 according to the collected voltage value and the resistance value of the sampling resistor. to the electrical parameter signals in the smart light strip.

在本实施例中，所述的智能灯带检测电路还包括：末端控制模块30；In this embodiment, the smart light strip detection circuit also includes: an end control module 30;

其中，所述末端控制模块30与所述智能灯带的尾端连接。The end control module 30 is connected to the rear end of the smart light strip.

应理解的是，在智能灯带驱动或运行过程中，仅仅是驱动端的控制器20通过驱动模块输出电压或电流至智能灯带中的各个发光模组，从智能灯带的长度方向上的首端输出信号至尾端，但是并不能接收尾端的相关信息。在部分应用场景下，需要根据尾端的情况对智能灯带的驱动或运行状态进行调节。在无法接收到尾端信号的情况下，根本无法对整个智能灯带进行调节。目前智能灯带的双向通信是通过特殊定制的LED驱动芯片以及相关的通信协议来实现的，这会大大增加产品的成本。It should be understood that during the driving or operation of the smart light strip, only the controller 20 at the driving end outputs voltage or current to each light-emitting module in the smart light strip through the driving module. The terminal outputs signals to the tail end, but cannot receive relevant information from the tail end. In some application scenarios, the driving or operating status of the smart light strip needs to be adjusted according to the conditions at the rear end. If the tail end signal cannot be received, the entire smart light strip cannot be adjusted at all. Currently, the two-way communication of smart light strips is achieved through specially customized LED driver chips and related communication protocols, which will greatly increase the cost of the product.

需要说明的是，末端控制模块30可以将尾端的信息通过智能灯带中的电流传输至控制器20。末端控制模块30中可以包括可变阻值的负载，该负载接入智能灯带。通过负载阻值的改变可以调节智能灯带中的电流值，从而在智能灯带中将待传输信息从智能灯带末端传输至智能灯带首端的控制器20。It should be noted that the end control module 30 can transmit the information of the end to the controller 20 through the current in the smart light strip. The terminal control module 30 may include a variable resistance load, which is connected to the smart light strip. The current value in the smart light strip can be adjusted by changing the load resistance, so that the information to be transmitted in the smart light strip is transmitted from the end of the smart light strip to the controller 20 at the head end of the smart light strip.

参照图5，在本实施例中，所述末端控制模块30包括：可变电阻R2和调节芯片U；Referring to Figure 5, in this embodiment, the terminal control module 30 includes: a variable resistor R2 and a regulating chip U;

其中，所述可变电阻R2串联于智能灯带的尾端，所述调节芯片U与可变电阻R2的控制端连接。Wherein, the variable resistor R2 is connected in series to the tail end of the smart light strip, and the adjustment chip U is connected to the control end of the variable resistor R2.

应理解的是，可变电阻R2为阻值可以动态调节的电阻。通过调节可变电阻R2的阻值可以动态的调节整个智能灯带内的阻值，在智能灯带内形成电流载波，通过该电流载波可以传输信息至控制器20。调节芯片U是用于对可变电阻R2的阻值进行调节的芯片。该调节芯片U可以接收外部指令，根据预先设定的程序调节可变电阻的阻值，例如需要反馈末端控制模块30的型号，可以将该可变电阻R2的阻值调节至该型号对应的预设值。阻值调节过程中可以是将可变电阻R2的阻值调节至一个固定的阻值，也可以是按照设定的频率进行调整，当然还可以按照其他方式进行调整，此处不做赘述。It should be understood that the variable resistor R2 is a resistor whose resistance can be dynamically adjusted. By adjusting the resistance of the variable resistor R2, the resistance in the entire smart light strip can be dynamically adjusted, forming a current carrier in the smart light strip, through which information can be transmitted to the controller 20. The adjustment chip U is a chip used to adjust the resistance of the variable resistor R2. The adjustment chip U can receive external instructions and adjust the resistance of the variable resistor according to a preset program. For example, if the model of the end control module 30 needs to be fed back, the resistance of the variable resistor R2 can be adjusted to the preset value corresponding to the model. Set value. During the resistance adjustment process, the resistance of the variable resistor R2 can be adjusted to a fixed resistance, or it can be adjusted according to a set frequency. Of course, it can also be adjusted in other ways, which will not be described here.

在具体调节过程中，所述调节芯片U可以在接收到待传输信息相关的指令时，根据所述待传输信息调节所述可变电阻R2的阻值，从而调节所述智能灯带内的电流，在智能灯带中形成电流载波；在智能灯带的尾端出现电流变化，首端同样会出现相同的电流变化，因此，所述控制器20可以在所述智能灯带内出现所述电流载波时，对所述电流载波进行解析，获得所述待传输信息。In the specific adjustment process, the adjustment chip U can adjust the resistance of the variable resistor R2 according to the information to be transmitted when receiving instructions related to the information to be transmitted, thereby adjusting the current in the smart light strip. , a current carrier is formed in the smart light strip; when a current change occurs at the tail end of the smart light strip, the same current change will also occur at the head end. Therefore, the controller 20 can cause the current to appear in the smart light strip. When the current carrier wave is generated, the current carrier wave is analyzed to obtain the information to be transmitted.

在本实施例中，所述调节芯片U可以根据所述待传输信息调节所述可变电阻R2的阻值大小，在所述智能灯带内形成预设电流值的电流载波。例如元数据信息对应的可变电阻R2的阻值为5欧姆，末端控制模块30的型号信息对应的可变电阻R2的阻值为10欧姆；在需要向控制器20传输元数据时，可以直接利用调节芯片U将可变电阻R2的阻值调节至5欧姆，从而在智能灯带中形成包括元数据信息的电流载波，该电流载波可以被控制器20接收并解析。其中预设电流值便是各种待传输信息在智能灯带中所体现的电流值，每个待传输信息对应的预设电流值并不相同。In this embodiment, the adjustment chip U can adjust the resistance of the variable resistor R2 according to the information to be transmitted, and form a current carrier with a preset current value in the smart light strip. For example, the resistance value of the variable resistor R2 corresponding to the metadata information is 5 ohms, and the resistance value of the variable resistor R2 corresponding to the model information of the terminal control module 30 is 10 ohms; when metadata needs to be transmitted to the controller 20, the resistance value can be directly The adjustment chip U is used to adjust the resistance of the variable resistor R2 to 5 ohms, thereby forming a current carrier including metadata information in the smart light strip, which can be received and analyzed by the controller 20 . The preset current value is the current value reflected by various information to be transmitted in the smart light strip. The preset current value corresponding to each information to be transmitted is different.

当然，可调节芯片U还可以根据所述待传输信息调节所述可变电阻R2的阻值变化频率，在所述智能灯带内形成预设频率的电流载波。例如可变电阻的阻值变化范围较小的情况下，也可以通过调节电阻的变化频率即在一定时间范围内多次将可变电阻R2的阻值从一个值调节至另一个值，从而在智能灯带中形成一定频率的电流变化即预设频率的电流载波。Of course, the adjustable chip U can also adjust the resistance change frequency of the variable resistor R2 according to the information to be transmitted, and form a current carrier wave of a preset frequency in the smart light strip. For example, when the resistance change range of the variable resistor is small, the resistance value of the variable resistor R2 can also be adjusted from one value to another value multiple times within a certain time range by adjusting the change frequency of the resistor. A certain frequency of current changes is formed in the smart light strip, that is, a current carrying current of a preset frequency. Wave.

此外，在本实施例中，调节芯片U还可以在调节可变电阻R2阻值的同时伴随一定的频率调节。通过阻值与频率结合的方式可以传输的待传输信息的种类更加丰富。所述待传输信息包括：末端控制模块的元数据信息、型号信息、功能信息以及版本信息，当然还可以包括一些给末端控制模块的控制命令，改变末端控制模块的固有状态，或者对外的一些功能信息。In addition, in this embodiment, the adjustment chip U can also adjust the resistance of the variable resistor R2 along with a certain frequency adjustment. The types of information to be transmitted that can be transmitted through the combination of resistance value and frequency are more abundant. The information to be transmitted includes: metadata information, model information, function information and version information of the terminal control module. Of course, it can also include some control commands to the terminal control module, change the inherent state of the terminal control module, or some external functions. information.

在本实施例中，控制器20还可以对智能灯带中是否正常接入末端控制模块30进行检测，例如在末端控制模块30连接异常等情况下，所述控制器20还可以根据接收到的所述电参数信号确定所述智能灯带尾端是否存在所述末端控制模块30。例如在智能灯带驱动完成之后，亦即当前智能灯带电路中的电流值或电阻总阻值稳定时，在末端控制模块30内的可变电阻R2的阻值发生变化时，智能灯带内的电流会发生相应的变化，控制模块20在接收到的电参数信号发生变化的情况下，即可认定存在末端控制模块30。In this embodiment, the controller 20 can also detect whether the terminal control module 30 is normally connected to the smart light strip. For example, if the terminal control module 30 is connected abnormally, the controller 20 can also detect whether the terminal control module 30 is connected abnormally. The electrical parameter signal determines whether the end control module 30 is present at the end of the smart light strip. For example, after the smart light strip driving is completed, that is, when the current value or the total resistance value of the resistor in the current smart light strip circuit is stable, when the resistance of the variable resistor R2 in the end control module 30 changes, the smart light strip will The current will change accordingly. When the electrical parameter signal received by the control module 20 changes, it can be determined that the end control module 30 exists.
