Description

免布线语音控制开关、相应的物联网***及其通讯方法Wiring-free voice control switch, corresponding Internet of Things system and communication method thereof 技术领域Technical field
本发明涉及物联网技术领域，具体涉及一种免布线语音控制开关、相应的物联网***及其通讯方法。The invention relates to the technical field of the Internet of things, in particular to a wiring-free voice control switch, a corresponding Internet of Things system and a communication method thereof.
背景技术Background technique
随着5G技术的推广，市场上涌现出很多家用或商用的物联网设备。物联网设备之间，一般遵循某种无线连接技术实现互联。802.11Wi-Fi无线通信标准是目前应用范围最广的无线接入技术标准之一。在物联网领域，Wi-Fi物联网接入方式更是应用最广，成本最低，可扩展性最好的物联网接入方式之一。通常，Wi-Fi物联网设备直接通过Wi-Fi接入点(Wi-Fi Access Point，也称Wi-Fi热点或无线路由器)接入网络。With the promotion of 5G technology, many home or commercial IoT devices have emerged on the market. IoT devices generally follow a certain wireless connection technology to achieve interconnection. The 802.11 Wi-Fi wireless communication standard is one of the most widely used wireless access technology standards. In the field of Internet of Things, Wi-Fi IoT access is one of the most widely used, lowest cost, and most scalable IoT access methods. Typically, Wi-Fi IoT devices access the network directly through a Wi-Fi Access Point (also known as a Wi-Fi hotspot or wireless router).
目前，市场上的家用或商用Wi-Fi物联网设备大多是通过手机、pad等移动端的应用来进行控制，许多时候并不方便。例如，市场上很流行的Wi-Fi物联网照明设备，通常是以移动端应用界面来控制照明设备的开关及调节亮度和色调，并搭配传统的机械开关进行简单的开关和亮度控制。上述开关控制方式的安排，既有应用界面控制的复杂与不便，又具有传统机械开关控制的位置不灵活与布线施工的冗余困难。At present, most of the home or commercial Wi-Fi IoT devices on the market are controlled by mobile terminals such as mobile phones and pads, and are often inconvenient. For example, Wi-Fi IoT lighting, which is popular on the market, usually uses a mobile application interface to control the lighting of the lighting device and adjust the brightness and hue, and with traditional mechanical switches for simple switching and brightness control. The arrangement of the above-mentioned switch control mode has the complexity and inconvenience of the application interface control, and the inflexibility of the traditional mechanical switch control and the redundancy of the wiring construction.
大多数情况下，对照明设备或其他常见的家用设备进行位置相对灵活的免除布线的实地控制方式，对用户更有吸引力。即无需对开关设备进行电源供电，而是给开关配以电池；开关与被控设备之间不再用电线连接，用户可以在一定的应用范围内，灵活安排理想的开关布设位置，并且可以方便的根据需要调整位置。In most cases, the relatively flexible, hands-free, field-based control of lighting or other common household equipment is more attractive to users. That is, there is no need to supply power to the switchgear, but the switch is equipped with a battery; the switch and the controlled device are no longer connected by wires, and the user can flexibly arrange the ideal switch layout position within a certain application range, and can be conveniently Adjust the position as needed.
基于上述的无线照明控制的需求，市场上已经出现了一些免布线无线遥控照明开关设备。这些免布线无线遥控照明开关设备以非标准化的方式在非标准化的频段(如1GHz、315MHz等)，使用私有通信方式，对照明设备进行简单的开关控制，不支持手机应用控制。但是，这些设备工作于非公共频段，容易与其他***的信号相互干扰，影响用户使用效果。Based on the above requirements for wireless lighting control, some wiring-free wireless remote control lighting switch devices have appeared on the market. These wiring-free wireless remote-controlled lighting switch devices use a proprietary communication method in a non-standardized manner in non-standardized frequency bands (such as 1 GHz, 315 MHz, etc.), and simple switching control of the lighting device does not support mobile application control. However, these devices work in non-public frequency bands and easily interfere with signals from other systems, affecting user performance.
同时，市场对于家居物联网设备的语音控制需求不断涌现，消费者在智 能家居时代越来越渴望摆脱传统的手控模式。语音控制模式无疑是一种非常方便的替代模式，有着广阔的市场前景。然而，市场上现有的声控开关设备，多采用有源有线方式连接，仅仅对环境声音进行简单检测放大，无法识别具体的声音来源与意义，无法做到复杂控制和精确控制。At the same time, the demand for voice control of home Internet of Things devices is constantly emerging, and consumers are increasingly eager to get rid of the traditional manual control mode in the smart home era. The voice control mode is undoubtedly a very convenient alternative mode with a broad market prospect. However, the existing voice-activated switchgear on the market mostly uses active wired connection, which simply detects and amplifies the ambient sound, cannot identify the specific sound source and meaning, and cannot achieve complex control and precise control.

具体实施方式detailed description
以下结合附图，通过详细说明一个较佳的具体实施例，对本发明做进一步阐述。The present invention will be further described below in detail with reference to the accompanying drawings.
本发明提出一种免布线语音控制开关，用于控制Wi-Fi物联网设备，所述Wi-Fi物联网设备的种类不限，例如可以是市场上常见的Wi-Fi物联网照明设备等应用功能设备，相应的本免布线语音控制开关可以是照明开关或其他具有功能控制开关。所述的免布线语音控制开关包含：语音采集单元1(如麦克风，麦克风阵列等)、语音命令特征库5、语音命令识别单元2、控 制命令检索生成单元3、第一Wi-Fi传输单元4、配对信息及控制命令列表6、配对升级控制单元7以及电池单元；所述的语音命令特征库5以及配对信息及控制命令列表6分别由存储单元实现。The invention provides a wiring-free voice control switch for controlling a Wi-Fi Internet of Things device, and the type of the Wi-Fi IoT device is not limited, for example, it may be a Wi-Fi Internet of Things lighting device commonly used in the market. The functional device, the corresponding free wired voice control switch can be a light switch or other function control switch. The wire-free voice control switch includes: a voice collection unit 1 (such as a microphone, a microphone array, etc.), a voice command feature library 5, a voice command recognition unit 2, a control command retrieval generation unit 3, and a first Wi-Fi transmission unit 4. The pairing information and control command list 6, the pairing upgrade control unit 7 and the battery unit; the voice command feature library 5 and the pairing information and the control command list 6 are respectively implemented by the storage unit.
如图1所示，所述的语音命令识别单元2连接所述的语音采集单元1以及语音命令特征库5，语音采集单元1实时采集用户语音信息，语音命令识别单元2将用户语音信息与命令特征库5中的语音命令特征进行匹配，得到匹配结果；所述的控制命令检索生成单元3连接所述的语音命令识别单元2以及配对信息及控制命令列表6，配对设备信息以及对应的控制命令均存储在该配对信息及控制命令列表6中，配对信息包含了MAC地址、通信密钥及预设包类型，控制命令检索生成单元3根据语音命令识别单元2的匹配结果生成相应控制命令；所述的第一Wi-Fi传输单元4连接所述的控制命令检索生成单元3以及配对升级控制单元7，将控制命令发送给Wi-Fi物联网设备，配对升级控制单元7还分别连接配对信息及控制命令列表6以及语音命令特征库5以通过外部服务器对配对信息、语音命令及固件进行升级。所述电池单元连接所述的语音采集单元1、语音命令识别单元2、控制命令检索生成单元3、第一Wi-Fi传输单元4以及配对升级控制单元7以向它们供电，随着半导体技术和语音处理技术的进步，低复杂度低功耗的本地实时语音监听采集和语音识别方式已经实现，可以保证电池供电的应用设备的电池更换或充电周期在可接受范围内。As shown in FIG. 1, the voice command recognition unit 2 is connected to the voice collection unit 1 and the voice command feature library 5. The voice collection unit 1 collects user voice information in real time, and the voice command recognition unit 2 transmits user voice information and commands. The voice command features in the feature library 5 are matched to obtain a matching result; the control command retrieval generating unit 3 is connected to the voice command recognition unit 2, the pairing information and the control command list 6, the paired device information, and the corresponding control command. The pairing information is stored in the pairing information and the control command list 6. The pairing information includes a MAC address, a communication key, and a preset packet type, and the control command retrieval generating unit 3 generates a corresponding control command according to the matching result of the voice command recognition unit 2; The first Wi-Fi transmission unit 4 is connected to the control command retrieval generation unit 3 and the pairing upgrade control unit 7, and sends a control command to the Wi-Fi Internet of Things device, and the pairing upgrade control unit 7 also connects the pairing information and Control command list 6 and voice command feature library 5 to match information and voice through an external server And firmware upgrade. The battery unit is connected to the voice collection unit 1, the voice command recognition unit 2, the control command retrieval generation unit 3, the first Wi-Fi transmission unit 4, and the pairing upgrade control unit 7 to supply power thereto, along with semiconductor technology and Advances in voice processing technology, low-complexity, low-power local real-time voice monitoring acquisition and speech recognition have been implemented to ensure that battery-changing or charging cycles for battery-powered applications are within acceptable limits.
配对升级控制单元7可以有两种控制模式，一种为本地控制更新配对设备信息，实现本地配对信息采集，不通过连接服务器；一种通过连接服务器，更新配对设备信息。语音命令以及控制软件更新，只通过连接服务器升级。The pairing upgrade control unit 7 can have two control modes, one is to update the paired device information for the local control, to realize the local pairing information collection, and not to connect to the server; and to update the paired device information by connecting to the server. Voice commands and control software updates are only upgraded by connecting to the server.
对Wi-Fi物联网设备的控制，一般是基于Wi-Fi链接。但是，像免布线语音控制开关这种控制信息产生间隔很长的物联网设备来说，若采用链接控制通信模式，则几乎每次要实现照明设备控制时，都要与照明设备重新建立Wi-Fi链接，会在控制帧上面消耗大部分能量，同时耗费更长的时间传输有效控制命令。对于主要以电池供电的免布线语音控制开关来说，基于Wi-Fi链接的控制方式会大大减少电池寿命。因此，本发明中，所述的第一Wi-Fi传输单元以MAC层非连接模式，通过在Wi-Fi单播包/广播包中加载私有信 息结构的方式向Wi-Fi物联网设备发送控制命令，可以使免布线语音控制开关在射频上发送最少数量的包，这样即可完成控制信息的传输，实现最小功耗，在最大程度上延长电池的更换或充电周期；较佳的，所述的单播包/广播包包含但不限于：Beacon包或ProbResp包或ProbReq包或Action包等不需要MAC连接的可以带私有定义IE的包类型。对于广播包，配对信息在私有定义的控制IE中；单播包可在包头的地址中区分配对设备，也可将配对信息放在私有定义的控制IE中。Control of Wi-Fi IoT devices is generally based on Wi-Fi links. However, if the control information such as the wiring-free voice control switch generates a long interval of IoT devices, if the link control communication mode is adopted, the Wi-device must be re-established with the lighting device almost every time the lighting device control is to be realized. The Fi link consumes most of the energy on the control frame and takes longer to transmit valid control commands. Wi-Fi link-based control greatly reduces battery life for battery-powered, hands-free voice-controlled switches. Therefore, in the present invention, the first Wi-Fi transmission unit transmits control to the Wi-Fi IoT device by loading a private information structure in a Wi-Fi unicast packet/broadcast packet in a MAC layer non-connection mode. The command can make the wiring-free voice control switch send a minimum number of packets on the radio frequency, so that the transmission of the control information can be completed, the minimum power consumption is realized, and the battery replacement or charging cycle is maximized; preferably, the The unicast/broadcast package includes but is not limited to: Beacon package or ProbResp package or ProbReq package or Action package, etc. Packet types that can be privately defined IE without MAC connection. For broadcast packets, the pairing information is in a privately defined Control IE; the unicast packet can distinguish the paired device in the address of the header, or the pairing information can be placed in a privately defined Control IE.
所述的免布线语音控制开关的语音采集单元1，在工作模式下，保持低功耗监听周边任何声音信号，当语音采集单元1判断监听到语音信号后，唤醒语音命令识别单元2，进行实时语音识别。当免布线语音控制开关的语音命令识别单元2识别到所采集的语音信息可以匹配语音命令特征库5中的某一条语音命令特征时，控制命令检索生成单元3根据匹配结果，生成相应的控制命令，然后在第一Wi-Fi传输单元4中将生成的控制命令，并不以MAC层的连接为基础，而是加载在多种可能的非加密或加密单播(unicast)/广播包中，以私有定义的控制信息元素(IE，Information Element)进行控制命令的传输。私有信息元素，即私有IE，根据Wi-Fi标准协议规定，厂商和供应商可以根据应用需要，定义MAC层的私有IE，以实现私有的通信需求。针对免布线语音控制开关的不同语音控制需求，可以定义不同类型的控制IE，实现对Wi-Fi物联网设备从简单到精细复杂的控制。控制IE在支持私有协议结构的Wi-Fi传输单元的MAC层中生成，在物理层加载至载波。上述的非加密或加密形式将在后文中具体说明。The voice collecting unit 1 of the wire-free voice control switch keeps any sound signal in the low-power listening state in the working mode. When the voice collecting unit 1 determines that the voice signal is monitored, the voice command identifying unit 2 is awakened to perform real-time. Speech Recognition. When the voice command recognition unit 2 of the wiring-free voice control switch recognizes that the collected voice information can match one of the voice command features in the voice command feature library 5, the control command retrieval generating unit 3 generates a corresponding control command according to the matching result. And then the generated control commands in the first Wi-Fi transmission unit 4 are not based on the connection of the MAC layer, but are loaded in a plurality of possible non-encrypted or encrypted unicast/broadcast packets. The control command is transmitted by a privately defined control information element (IE, Information Element). Private information elements, that is, private IEs, according to the Wi-Fi standard protocol, vendors and vendors can define private IEs of the MAC layer according to application needs to achieve private communication needs. Different types of control IEs can be defined for different voice control requirements of the hands-free voice control switch, enabling simple to fine control of Wi-Fi IoT devices. The Control IE is generated in the MAC layer of the Wi-Fi transmission unit supporting the proprietary protocol structure and loaded to the carrier at the physical layer. The above non-encrypted or encrypted form will be specifically described later.

To implement the non-connected communication mechanism of the present invention on a standard Wi-Fi IoT device, only a small modification of the software portion of the MAC layer is required, even at the application layer, so that the existing Wi-Fi chip can be used. The implementation is implemented by changing the MAC layer software to support the defined private IE; or changing the application layer software to support the defined private IE, which is easy to implement, low in implementation cost, and simple in method.

根据所用加载控制IE的不同类型的包和应用场景的要求，Wi-Fi物联网设备中第二Wi-Fi传输单元对收到的包的确认的形式可以有三种：1)可以由应用层或MAC层软件定义确认IE，加载于上述的Wi-Fi单播/广播包类型上，用于Wi-Fi物联网设备对收到的控制命令的高层确认。加载确认IE的包可以为，但不局限于ProbResp包、Action包等不需要MAC连接的可以带私有定义IE的包类型；2)不用高层确认，对某些类型的包，仅靠Wi-Fi标准规定MAC硬件自动回复ACK包；3)对某些包类型，不采用任何的确认，Wi-Fi标准规定MAC硬件也不自动回复ACK包。且上述的包类型、确认形式和加密形式可以根据具体情况自由组合使用。According to the requirements of different types of packages and application scenarios of the load control IE used, the second Wi-Fi transmission unit in the Wi-Fi IoT device may have three forms of confirmation of the received packet: 1) may be applied by the application layer or The MAC layer software definition confirmation IE is loaded on the above-mentioned Wi-Fi unicast/broadcast packet type for high-level confirmation of the received control command by the Wi-Fi IoT device. The package that loads the confirmation IE can be, but is not limited to, the ProbResp package, the Action package, etc., which can be carried out with a private definition IE without a MAC connection; 2) without high-level confirmation, for some types of packages, only Wi-Fi The standard stipulates that the MAC hardware automatically replies to the ACK packet; 3) does not use any acknowledgment for certain packet types, and the Wi-Fi standard stipulates that the MAC hardware does not automatically reply to the ACK packet.
