Abstract

A control system for a power backup system. Since a NOT gate circuit is arranged between a main controller and a standby battery, the main controller can output a high level when controlling an electrical energy output function of the standby battery to be turned on, and can output a low level when controlling the electrical energy output function of the standby battery to be turned off. That is to say, when the main controller completes the execution of a power backup program and controls a computer device to be powered off, even if the main controller itself outputs a low level due to an insufficient power supply voltage, the low level, after being subjected to high-low inversion of the NOT gate circuit, still controls the electrical energy output function of the standby battery to be turned off, and the electrical energy output function of the standby battery is not enabled again. A power-off operation can be smoothly executed, electrical energy is saved, and the service life of a related device, such as a standby battery, is prolonged. A control method for a power backup system, wherein the method has the same beneficial effects as the control system for a power backup system.

The main controller of the computer equipment can control the backup battery to supply power for a period of time when the main power supply of the computer equipment is powered off, and complete the storage and control of related data during this period. The computer equipment is powered off. Normally, the main controller will output a low-level control signal to the backup battery to enable the power output function of the backup battery. During the process of completing the backup power program and controlling the power off of the computer equipment , The main controller will output a high-level control signal to control the discharging function of the backup battery to turn off. However, during the power-off process, as the main controller's power supply voltage decreases, the original high-level output of the main controller may be It will drop to a low level, so it may cause the power output function of the backup battery to be enabled again, and the computer equipment will be powered on again and perform the backup power process. This process is obviously unnecessary, which increases the waste of power and reduces The life span of related devices such as backup batteries.

本发明提供了一种备电***的控制***，由于在主控制器与备用电池之间设置了非门电路，如此一来，主控制器在控制开启备用电池的电能输出功能时可以输出高电平，而在控制关闭备用电池的电能输出功能时输出低电平即可，也就是说，在主控制器执行完毕备电程序并控制计算机设备下电时，即使主控制器自身由于供电电压不足而输出了低电平，低电平在经过非门电路的高低反转后仍然会控制备用电池的电能输出功能关闭，不会再次使能备用电池的电能输出功能，能够顺利执行下电操作，节省了电能，延长了备用电池等相关器件的寿命。The present invention provides a control system for a backup power system.

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
请参考图1，图1为本发明提供的一种备电***的控制***的结构示意图，包括：Please refer to Figure 1. Figure 1 is a schematic structural diagram of a control system for a backup power system provided by the present invention, including:
与计算机设备的主电源以及主控制器2连接的电能传感器1，用于检测主电源的预设类型的电能参数；The electric energy sensor 1 connected to the main power supply of the computer equipment and the main controller 2 is used to detect the preset type of electric energy parameters of the main power supply;
主控制器2，用于在电能参数低于第一预设阈值时，输出高电平并执行备电程序，并在备电程序执行完毕时输出低电平；The main controller 2 is configured to output a high level and execute a power backup program when the electric energy parameter is lower than a first preset threshold, and output a low level when the power backup program is executed;
与主控制器2连接的非门电路3，用于将高电平以及低电平进行高低反转后传输至备用电池4；The NOT circuit 3 connected to the main controller 2 is used to invert the high level and the low level and transmit them to the backup battery 4;
与非门电路3连接的备用电池4，用于在接收到高低反转后的高电平时开启电能输出功能，在接收到高低反转后的低电平时关闭电能输出功能。The backup battery 4 connected to the NAND circuit 3 is used to turn on the power output function when receiving the high level after the high and low inversion, and turn off the power output function when receiving the low level after the high and low inversion.
具体的，电能传感器1及其检测的预设类型的电能参数可以为多种类型，例如可以为电压传感器或者电流传感器等，相应的电能参数可以为电压值或者电流值，且其中的预设阈值可以根据实际经验进行自主设定，本发明实施例在此不做限定。Specifically, the electric energy sensor 1 and the electric energy parameter of the preset type detected by it may be of multiple types, for example, it may be a voltage sensor or a current sensor, etc., and the corresponding electric energy parameter may be a voltage value or a current value, and the preset threshold value therein It can be set independently according to actual experience, and the embodiment of the present invention is not limited herein.
具体的，为了解决主控制器2在下电过程中由于供电电压过低，其自动输出的低电平会导致备用电池4的电能输出功能再次开启的问题，本发明实施例中设置了非门电路3，将非门电路3设置在主控制器2与备用电池4之间，利用非门电路3的高低反转功能，可以将主控制器2由于供电电压过低而自动输出的低电平转换为高电平后再传输至备用电池4，如此一来，主控制器2由于供电电压过低而不可控制的输出低电平时，便不会再导致备用电池4的电能输出功能开启，节省了备用电池4中的电能且延长了备用电池4等相关器件的使用寿命。Specifically, in order to solve the problem that the automatic output low level of the main controller 2 will cause the power output function of the backup battery 4 to be turned on again due to the low power supply voltage during the power-off process, a non-gate circuit is provided in the embodiment of the present invention. 3. Set the NOT circuit 3 between the main controller 2 and the backup battery 4, and use the high-low reversal function of the NOT circuit 3 to convert the low-level output of the main controller 2 due to the low power supply voltage. After being at a high level, it is transmitted to the backup battery 4. As a result, when the main controller 2 outputs a low level that cannot be controlled due to the low power supply voltage, it will no longer cause the power output function of the backup battery 4 to be turned on, saving The electric energy in the backup battery 4 extends the service life of related devices such as the backup battery 4.
其中，由于设置了非门电路3，而备用电池4的电能输出功能的使能需要低电平来触发，因此可以更改主控制器2中的程序，使其来欲控制备用电池4的电能输出功能开启时输出的电平由低电平变为高电平，如此一来，在主控制器2欲控制备用电池4的电能输出功能开启时便会输出高电平，高电平经由非门电路3可以转变为低电平并控制备用电池4的电能输出功能开启，能够顺利地实现原有的主控制器2对于备用电池4的电能输出功能的控制功能，且解决了上述的技术问题。Among them, because the inverter circuit 3 is set, and the enabling of the power output function of the backup battery 4 needs to be triggered by a low level, the program in the main controller 2 can be changed to control the power output of the backup battery 4. When the function is turned on, the output level changes from low level to high level. In this way, when the main controller 2 wants to control the power output function of the backup battery 4, it will output a high level, and the high level will pass through the NOT gate. The circuit 3 can be converted to a low level and control the power output function of the backup battery 4 to turn on, which can smoothly implement the original main controller 2's control function of the power output function of the backup battery 4 and solve the above technical problems.
本发明提供了一种备电***的控制***，由于在主控制器与备用电池之间设置了非门电路，如此一来，主控制器在控制开启备用电池的电能输出功能时可以输出高电平，而在控制关闭备用电池的电能输出功能时输出低电平即可，也就是说，在主控制器执行完毕备电程序并控制计算机设备下电时，即使主控制器自身由于供电电压不足而输出了低电平，低电平在经过非门电路的高低反转后仍然会控制备用电池的电能输出功能关闭，不会再次使能备用电池的电能输出功能，能够顺利执行下电操作，节省了电能，延长了备用电池等相关器件的寿命。The present invention provides a control system for a backup power system. Because a non-gate circuit is set between the main controller and the backup battery, the main controller can output high power when the power output function of the backup battery is controlled to be turned on. When the power output function of the backup battery is controlled to be turned off, it is sufficient to output a low level, that is, when the main controller finishes executing the backup power program and controls the computer equipment to be powered off, even if the main controller itself is due to insufficient power supply voltage When the low level is output, the low level will still control the power output function of the backup battery to be turned off after the high and low inversion of the NOT circuit, and will not enable the power output function of the backup battery again, and the power-off operation can be performed smoothly. It saves power and extends the life of related devices such as backup batteries.

具体的，设置于备用电池4的电能输出端以及主控制器2之间的可控开关6可以为多种类型，例如MOS(金氧半场效晶体管，Metal-Oxide-Semiconductor Field-Effect Transistor)管等，主控制器2通常可以输出电流信号来驱动可控开关6导通，从而使得备用电池4为主控制器2供电，而电流信号的电流值(在一定范围内)越大，那么该电流信号便可以更快地驱动可控开关6导通，工作人员可以根据可控开关6的具体类型，预先设置与主控制器2连接的自举电容7的容值，通过设置合适的容值，可以使得主控制器2输出的开关控制信号的电流值在一个较大的值上，如此一来，该开关控制信号便具有较强的驱动能力，能够快速地驱动可控开关6导通，从而加快了备用电池4的电能输出，能够快速完成从主电源到备用电池4供电的切换从而执行备电程序，提高了数据的安全性。Specifically, the controllable switch 6 provided between the power output terminal of the backup battery 4 and the main controller 2 can be of various types, such as MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) The main controller 2 can usually output a current signal to drive the controllable switch 6 to turn on, so that the backup battery 4 supplies power to the main controller 2. The larger the current value (within a certain range) of the current signal, the greater the The current signal can drive the controllable switch 6 to turn on faster. The staff can preset the capacitance value of the bootstrap capacitor 7 connected to the main controller 2 according to the specific type of the controllable switch 6, and set the appropriate capacitance value. , The current value of the switch control signal output by the main controller 2 can be made at a larger value. In this way, the switch control signal has a strong driving ability and can quickly drive the controllable switch 6 to be turned on. This speeds up the power output of the backup battery 4, and can quickly complete the switch from the main power supply to the backup battery 4 power supply to execute the backup program, thereby improving the security of data.
其中，自举电容7的电容值与主控制器2输出的开关控制信号的电流值有对应关系，而不同类型的可控开关6在不同电流值的开关控制信号的驱动下的导通速度不同，工作人员可以根据经验来自主对自举电容7的电容值进行设定，本发明实施例在此不做限定。Among them, the capacitance value of the bootstrap capacitor 7 has a corresponding relationship with the current value of the switch control signal output by the main controller 2, and different types of controllable switches 6 have different conduction speeds driven by switch control signals of different current values. The worker can set the capacitance value of the bootstrap capacitor 7 according to experience, which is not limited in the embodiment of the present invention.
其中，MOS管类型的可控开关6可以为两路并联在一起的MOS管，每一路MOS管中可以包含任意数量的MOS管，例如可以为包含一个或者两个等，本发明实施例在此不做限定。Among them, the controllable switch 6 of the MOS tube type may be two MOS tubes connected in parallel, and each MOS tube may contain any number of MOS tubes, for example, it may include one or two, etc. The embodiment of the present invention is here. Not limited.
为了更好地对本发明实施例进行说明，请参考图4，图4为本发明提供的一种备用电池4的放电使能控制回路的结构示意图，作为一种优选的实施例，该备电***的控制***还包括：In order to better describe the embodiment of the present invention, please refer to FIG. 4. FIG. 4 is a schematic structural diagram of a discharge enable control loop of a backup battery 4 provided by the present invention. As a preferred embodiment, the power backup system The control system also includes:
分别与主控制器2以及备用电池4连接的多条通讯回路，用于实现主控制器2以及备用电池4之间的预设信息的交互；Multiple communication circuits respectively connected to the main controller 2 and the backup battery 4 are used to realize the interaction of preset information between the main controller 2 and the backup battery 4;
负极与通讯回路连接，正极接地的浪涌电流吸收器件D1，用于吸收瞬间的浪涌电流。The negative pole is connected to the communication circuit, and the surge current absorbing device D1 with the positive pole grounded is used to absorb the instantaneous surge current.
具体的，在备电过程中以及备电过程前后，主控制器2都需要与备用电池4进行多种类型的信息交互，例如主控制器2可以通过I2C总线与备 用电池4进行信号交互并采集备用电池4的工作状态(例如电量信息以及故障情况等)，还可以向备用电池4发送备用电池4测试信号BBUTEST、备用电池4充电信号BBUCHARGE、***准备信号SYSPRE以及电能输出功能使能信号BBUENABLE等，而几乎每一种信号都有自己专属的通讯回路，本发明实施例在此不做限定。Specifically, during the backup process and before and after the backup process, the main controller 2 needs to exchange various types of information with the backup battery 4. For example, the main controller 2 can interact and collect signals with the backup battery 4 through the I2C bus. The working status of the backup battery 4 (such as power information and fault conditions, etc.), the backup battery 4 test signal BBUTEST, the backup battery 4 charging signal BBUCHARGE, the system preparation signal SYSPRE, and the energy output function enable signal BBUENABLE, etc. , And almost every signal has its own dedicated communication loop, which is not limited in the embodiment of the present invention.
其中，为了保证每条通讯回路中信号传输的正确性以及稳定性，本发明实施例中在每条通讯回路中设置了浪涌电流吸收器件D1，其可以吸收瞬间的浪涌电流，例如外界的静电干扰以及雷击干扰等，本发明实施例在此不做限定。Among them, in order to ensure the correctness and stability of signal transmission in each communication loop, a surge current absorbing device D1 is provided in each communication loop in the embodiment of the present invention, which can absorb instantaneous surge current, such as external Electrostatic interference and lightning interference, etc., are not limited in the embodiment of the present invention.
作为一种优选的实施例，浪涌电流吸收器件D1为TVS(Transient Voltage Suppressor，瞬态二极管)。As a preferred embodiment, the surge current absorbing device D1 is a TVS (Transient Voltage Suppressor, transient diode).
其中，TVS具有体积小、价格低以及使用寿命长等优点。Among them, TVS has the advantages of small size, low price and long service life.
当然，除了TVS外，浪涌电流吸收器件D1还可以为其他多种类型，本发明实施例在此不做限定。Of course, in addition to the TVS, the surge current absorbing device D1 can also be of various other types, which are not limited in the embodiment of the present invention.

串接于通讯回路中的限流电阻R2，用于限制通讯回路中的电流值。The current-limiting resistor R2 connected in series in the communication loop is used to limit the current value in the communication loop.
具体的，TVS虽然可以在外界产生高电压时将高电压箝位在一个较低的数值，例如箝位在2V，但是箝位后的较小的电压值依然会增大通讯回路中的电流，而通讯回路一般均为小电流负载的回路，若通讯回路中的电流值过大可能会损坏相关器件，因此可以在通讯回路中串接限流电阻R2，从而限制通讯回路中的电流值，对通讯回路中的相关器件起到了保护作用。Specifically, although TVS can clamp the high voltage to a lower value when the external high voltage is generated, such as 2V, the smaller voltage value after clamping will still increase the current in the communication loop. The communication circuit is generally a circuit with a small current load. If the current value in the communication circuit is too large, it may damage the related devices. Therefore, a current-limiting resistor R2 can be connected in series in the communication circuit to limit the current value in the communication circuit. The related devices in the communication loop play a protective role.
其中，限流电阻R2可以为多种类型，本发明实施例在此不做限定。Wherein, the current limiting resistor R2 can be of multiple types, which is not limited in the embodiment of the present invention.
作为一种优选的实施例，该备电***的控制***还包括：As a preferred embodiment, the control system of the power backup system further includes:

具体的，滤波电路8可以对通讯回路中的信号进行滤波处理，过滤掉其中的杂波干扰，从而使得主控制器2以及备用电池4能够接收到更加稳定准确的信号，增强备电***的稳定性以及可靠性，进一步提高了计算机设备在主电源掉电后的数据安全性。Specifically, the filter circuit 8 can filter the signals in the communication loop to filter out the clutter interference, so that the main controller 2 and the backup battery 4 can receive more stable and accurate signals, and enhance the stability of the backup power system. Performance and reliability, and further improve the data security of the computer equipment after the main power supply is cut off.
其中，滤波电路8可以为多种类型，例如可以为RC滤波电路8等，本发明实施例在此不做限定。The filter circuit 8 may be of multiple types, for example, it may be an RC filter circuit 8, etc., which is not limited in the embodiment of the present invention.
作为一种优选的实施例，主控制器2还用于：As a preferred embodiment, the main controller 2 is also used for:
预先将高电平信号、低电平信号、开关控制信号以及待发送至通讯回路的信号通过滤波算法处理后输出。The high-level signal, the low-level signal, the switch control signal, and the signal to be sent to the communication loop are processed by filtering algorithms before output.
具体的，考虑到仅仅从硬件上对信号进行滤波还不足以完全消除信号中的干扰量以及不稳定因素，本发明实施例中的主控制器2在输出信号前可以通过滤波算法对欲发送的信号消除抖动后再输出，能够使得备电***中流通的信号更加稳定可靠，进一步提高了备电***的可靠性。Specifically, considering that only filtering the signal from the hardware is not enough to completely eliminate the interference and unstable factors in the signal, the main controller 2 in the embodiment of the present invention can use a filtering algorithm to filter the signal to be sent before outputting the signal. The signal is output after the jitter is eliminated, which can make the signal circulating in the backup power system more stable and reliable, and further improve the reliability of the backup power system.

其中，滤波算法可以为多种类型，本发明实施例在此不做限定。Among them, the filtering algorithm may be of multiple types, which are not limited in the embodiment of the present invention.
作为一种优选地实施例，在电能参数低于第一预设阈值时具体为：As a preferred embodiment, when the electric energy parameter is lower than the first preset threshold, specifically:
判断电能参数的电平是否由高电平转变为低电平；Determine whether the level of the electric energy parameter changes from a high level to a low level;
若电能参数的电平由高电平转变为低电平，则判断由高电平转变的低电平是否能够持续预设时长；If the level of the electric energy parameter changes from a high level to a low level, it is determined whether the low level converted from the high level can last for a preset time;
若由高电平转变的低电平能够持续预设时长，则判定电能参数低于第一预设阈值，主电源掉电。If the low level transitioning from the high level can last for the preset time, it is determined that the electric energy parameter is lower than the first preset threshold, and the main power supply is powered off.
具体的，为了防止波动产生的电平的高低变化对于判断结果产生影响，本发明实施例中可以在电能参数的电平由高电平转变为低电平后，且低电平能够保持稳定预设时长的情况下，判定电能参数低于第一预设数值，也即判定主电源掉电，采用此种方法能够防止在电平短时波动时错误判定主电源掉电，从而提高了判定结果的准确性，也就提高了备电***的控制***的可靠性。Specifically, in order to prevent the level change caused by the fluctuation from affecting the judgment result, in the embodiment of the present invention, after the level of the electric energy parameter changes from a high level to a low level, and the low level can maintain a stable preset value. When the duration is set, it is determined that the electric energy parameter is lower than the first preset value, that is, the main power supply is determined to be powered down. This method can prevent the wrong determination of the main power supply failure when the level fluctuates for a short time, thereby improving the determination result The accuracy of this improves the reliability of the control system of the backup power system.
其中，预设时长可以进行自主设定，本发明实施例在此不做限定。Among them, the preset duration can be set independently, which is not limited in the embodiment of the present invention.
作为一种优选地实施例，判断电能参数的电平是否由高电平转变为低电平具体为：As a preferred embodiment, determining whether the level of the electric energy parameter changes from a high level to a low level is specifically:
获取电能参数连续的两个采样信号；Obtain two consecutive sampling signals of electric energy parameters;
判断连续的两个采样信号电压差值的绝对值是否大于第二预设阈值；Judging whether the absolute value of the voltage difference between two consecutive sampled signals is greater than the second preset threshold;
若连续的两个采样信号电压差值的绝对值大于第二预设阈值，且连续的两个采样信号中最后一次获取的采样信号的电压值小于第一预设阈值，则判定电能参数的电平由高电平转变为低电平。If the absolute value of the voltage difference between two consecutive sampling signals is greater than the second preset threshold, and the voltage value of the last acquired sampling signal in the two consecutive sampling signals is less than the first preset threshold, then the electrical energy parameter is determined The level changes from high to low.
具体的，之所以要获取电能参数连续的两个采样信号，是因为通过电能参数连续的两个采样信号可以判定出电能参数的电平是否发生了“低-高”或者“高-低”的变化，其中，若两个采样信号电压差值的绝对值大于第二预设阈值，则可以证明两个采样信号的电压差值过大，也即证明电能参数的电平发生了“低-高”或者“高-低”的变化。Specifically, the reason for obtaining two consecutive sampling signals of electric energy parameters is because the two consecutive sampling signals of electric energy parameters can determine whether the level of the electric energy parameters is "low-high" or "high-low". Change, where, if the absolute value of the voltage difference between the two sampling signals is greater than the second preset threshold, it can be proved that the voltage difference between the two sampling signals is too large, that is, it proves that the level of the electric energy parameter has occurred "low-high". "Or "high-low" changes.
具体的，在判定电能参数的电平发生了“低-高”或者“高-低”的变化之后，通过判定两个采样信号中最后一次获取的采样信号的电压值小于第一预设阈值，随机可以证明最后一次获取的采样信号属于低电平，那么也就可以证明电能参数的电平发生了“高-低”的变化，本发明实施例中的判定电能参数的电平发生由高到低变化的方法步骤较少，速度快，且准确性较高。Specifically, after determining that the level of the electric energy parameter has a "low-high" or "high-low" change, by determining that the voltage value of the last sampled signal obtained in the two sampled signals is less than the first preset threshold, It can be proved at random that the last sampled signal acquired belongs to the low level, and then it can be proved that the level of the electric energy parameter has changed from high to low. In the embodiment of the present invention, the level of determining the electric energy parameter changes from high to low. The low-variation method has fewer steps, is fast, and has higher accuracy.
当然，除了本发明实施例中判定电能参数的电平发生由高到低变化的方法外，判定电能参数的电平发生由高到低变化的方法还可以为其他具体形式，本发明实施例在此不做限定。Of course, in addition to the method for determining that the level of an electric energy parameter changes from high to low in the embodiment of the present invention, the method for determining that the level of an electric energy parameter changes from high to low can also be in other specific forms. This is not limited.
具体的，判断由高电平转变的低电平是否能够持续预设时长可以通过连续的采样信号进行判断，例如可以在之前的两个采样信号的基础上再次采样一个新的采样信号，每采样得到一个新的采样信号便可以将最近获取的两个采样信号进行对比，若最近获取的两个采样信号的电压差值不大于第二预设阈值，那么可以证明在这两个采样点对应的时刻，电能参数的电平高低没有发生变化，也即证明了在一个采样周期内，电能参数的信号保持在了低电平，可以如此反复地判断，直至得到“由高电平转变的低电平是否能够持续预设时长”的判定结果即可。Specifically, judging whether the low level transitioned from the high level can last for a preset period of time can be judged by continuous sampling signals. For example, a new sampling signal can be sampled again on the basis of the previous two sampling signals. When a new sampling signal is obtained, the two recently acquired sampling signals can be compared. If the voltage difference between the two recently acquired sampling signals is not greater than the second preset threshold, it can be proved that the two sampling points correspond to each other. At the moment, the level of the electric energy parameter does not change, which proves that the signal of the electric energy parameter is kept at a low level within a sampling period. The judgment can be repeated in this way until a low-level transition from a high level is obtained. The judgment result of “Ping can last for a preset time” is sufficient.
其中，第二预设阈值均可以进行自主设定，例如第二预设阈值可以设置为高电平标准值的20％等，当然，在判断连续的两个采样信号电压差值的绝对值时，具体可以为“判断连续的两个采样信号电压差值的绝对值是 否大于第二预设阈值且小于第三预设阈值”，考虑到两个采样信号的绝对差值通常不会太大，除非遇到信号波动的情况下，因此可以在“连续的两个采样信号电压差值的绝对值大于第二预设阈值且小于第三预设阈值”的情况下执行后续步骤，当连续的两个采样信号电压差值的绝对值小于第二阈值可以判定电平高低没有变化，当连续的两个采样信号电压差值的绝对值大于第三预设阈值则可以判定为最新的采样信号为干扰信号，其中，第三预设阈值也可以进行自主设定，例如可以设定为高电平标准值的120％等，本发明实施例在此不做限定。Among them, the second preset threshold can be set independently, for example, the second preset threshold can be set to 20% of the high-level standard value, etc. Of course, when judging the absolute value of the voltage difference between two consecutive sampled signals Specifically, it can be "determine whether the absolute value of the voltage difference between two consecutive sampling signals is greater than the second preset threshold and less than the third preset threshold", considering that the absolute difference between the two sampling signals is usually not too large, Unless the signal fluctuates, the following steps can be performed when "the absolute value of the voltage difference between two consecutive sampled signals is greater than the second preset threshold and less than the third preset threshold." The absolute value of the voltage difference of a sampled signal is less than the second threshold to determine that the level has not changed. When the absolute value of the voltage difference of two consecutive sampled signals is greater than the third preset threshold, it can be determined that the latest sampled signal is interference The third preset threshold can also be set independently, for example, it can be set to 120% of the high-level standard value, etc., which is not limited in the embodiment of the present invention.
其中，第一预设阈值可以进行自主设定，例如可以设定为高电平标准值的40％等，当连续的两个采样信号中最后一次获取的采样信号的电压值小于第一预设阈值，则可以判定最新采集到的采样信号为低电平，否则为高电平，本发明实施例在此不做限定。Among them, the first preset threshold can be independently set, for example, it can be set to 40% of the high-level standard value, etc., when the voltage value of the last sampled signal acquired in two consecutive sampled signals is less than the first preset Threshold, it can be determined that the newly collected sampling signal is low level, otherwise it is high level, which is not limited in this embodiment of the present invention.
