The processor may be a central processing unit, a microprocessor, an image processor, a digital signal processor, or any other suitable processor. The processor has data and/or signal processing functions. The processor may be implemented in software, hardware, or a combination of the two. Non-transitory computer-readable storage media include any suitable media that can store program code, such as magnetic disks, hard disks, optical disks, flash memory, read-only memory, random-access memory, and the like. The term "A and/or B" means all possible combinations of A and B, such as just A, just B, or A and B. The terms "at least one A or B" or "at least one of A and B" have a similar meaning to "A and/or B" and can include just A, just B, or A and B. The terms "a" and "the" in the singular may also include the plural.

In this embodiment of the present invention, reference is made to a structural block diagram of an embodiment of an independent wireless networking device shown in FIG. 2 . The wireless networking device at least includes: a microcontroller unit MCU, a liquid crystal LED display module, a USB power input module, an outdoor unit module communication interface for wireless communication with the outdoor unit, and an indoor unit module communication interface for wireless communication with the indoor unit. Among them, in the same space, there are one or more outdoor units and one or more indoor units, that is, there can be multiple sets of units in the same space. Wherein, one outdoor unit can be networked with one or more indoor units, and control one or more indoor units after the network is formed. The wireless networking device realizes the control of wireless networking communication, and can independently and conveniently control the automatic networking of indoor and outdoor units and corresponding wireless communication modules (routers, coordinators, etc.) or offline testing during production.

Referring to FIG. 3 , an example of a wireless networking communication scenario of indoor and outdoor units of an air conditioner according to the present invention. In the case of wired network communication, the actual building installation is multi-connected. Due to space constraints, outdoor units are installed on the flat (such as the top or bottom of the building) or even across buildings, while the indoor unit and outdoor unit are connected through wired The communication line connection has long communication distance, stable system, fast transmission rate, and signal strength is not limited by walls or controls, but it faces the trouble of complicated installation process, confusion of communication cables, and high frequency of maintenance errors. With the development of wireless communication technology, it is possible to connect outdoor units and indoor units with multiple connections in a building by means of wireless communication, so that installation management can be realized more simply and quickly. For a set of indoor and outdoor units wireless communication, it can be configured by one outdoor unit and multiple indoor units, preferably Zigbee wireless communication provides a wireless communication network between indoor and outdoor units, mainly through coordinators, routers , terminal node, data packet, data path and control path realize wireless communication data transmission and control command transmission between a set of indoor and outdoor units after completing the configuration and networking.

Specifically, the coordinator is usually installed on the outdoor unit. The coordinator of the Zigbee network is used to establish and manage the Zigbee wireless network. Each Zigbee wireless network only allows one Zigbee coordinator. The coordinator is set on each outdoor unit of the unit. The outdoor unit transmits unit information and control commands to one or more indoor units that communicate with its wireless network. When the Zigbee wireless network is completed, other indoor units within the Zigbee range can apply to join the Zigbee network as nodes/modules . While the router is installed on the indoor unit, a Zigbee wireless network can have multiple Zigbee routers, and one router can represent a node/indoor unit module, which is used to receive the coordinator information and forward the messages of other nodes. For the same set of units, the indoor unit and the outdoor unit are set to the same group number. When the indoor unit and the outdoor unit are networked, the Zigbee coordinator of the outdoor unit allows the indoor unit with the same number as the outdoor unit to join the network, and the networking process can be realized by the wireless networking device of the present invention, which is an independent device , which can be external or built into the Zigbee coordinator.

Specifically, for an outdoor unit configured with a Zigbee coordinator, an outdoor unit wireless network is established, and the same group number is pre-allocated to one or more indoor units belonging to the same unit as an outdoor unit, such as a DIP switch. In this way, multiple units located in the same space area/location can be distinguished. The outdoor unit numbers of different units are different, and the corresponding indoor unit numbers of different units are also different. When the indoor unit applies to join the Zigbee network, the group number of the indoor unit can be It is used by the coordinator as the basis for judging whether to allow joining of the unit, so that the indoor units and outdoor units of multiple units in the same space are pre-classified. After the assignment, the unit is powered on, the coordinator on the outdoor unit forms a wireless network, and the outdoor unit sends a networking request to the coordinator and joins the outdoor unit to the network. Then it can receive the networking request sent by the indoor unit, and join the wireless network formed by the Zigbee coordinator at the outdoor unit. The coordinator also allows other nodes to join, and the networking request from the indoor unit will decide whether to allow it to join according to the situation, for example: indoor The machine searches for the coordinator of the surrounding network, obtains the coordinator information, and then sends a networking request to the corresponding coordinator according to the information, and the networking request contains the group number. After the coordinator receives the networking request, it sends a notification to the corresponding indoor unit. The indoor unit suspends searching for other coordinators and suspends sending the networking request. If it does not receive the networking connection notification within a period of time, it will continue to send networking. ask. The coordinator judges the received networking request to determine whether it is consistent with its own outdoor unit number. If yes, it is the same unit and the indoor unit joins the network, assigns a unique communication address to the indoor unit, and completes the Zigbee networking communication of the air conditioner. . The coordinator can also actively search for the indoor unit after the outdoor unit network according to the obtained group number to determine whether the group number of the indoor unit is consistent with the group number of the outdoor unit where it is located. The machine in turn assigns a unique communication address.

According to the technical solution of the wireless networking communication of the present invention, the realization of the air conditioner through the Zigbee networking communication is mainly realized by the built-in or external wireless networking device that works with the Zigbee coordinator.

As an example of a wireless networking device shown in Figure 2, the USB power input module has a USB interface, which can be connected to the power terminal to obtain power, such as DC 5V power, for the work of the MCU control unit. If it is built in the coordinator, the working power of the MCU control unit can also be obtained directly by connecting the power supply of the coordinator.

In the function setting module, at least two functions can be preset, such as the function of offline detection of the wireless networking device itself or the function of performing networking through the device.

The wireless networking device itself is provided with an interface for wireless communication with the outdoor unit module and an interface for communication with the indoor unit module. Correspondingly, the outdoor unit module and the indoor unit module are also provided with corresponding interfaces for realizing wireless communication. These communication interfaces can be, for example, Wifi interfaces, various short-range communication interfaces, and the like. Preferably, a Zigbee communication interface.

According to the function set by the function setting module, the MCU control unit executes the corresponding function to communicate, network or detect the outdoor unit module and the indoor unit module. After the function execution process is completed, different states will be displayed through the LED display module to indicate the state of each stage. For example, when the outdoor unit finds the T3 frequency of the indoor unit flickering during networking, it is always on when the network information is locked. For example, when detecting The outdoor unit finds that the T1S frequency of the indoor unit flickers, and the flicker times out (over the set T2 duration) and goes out.

An embodiment of the method for implementing the wireless networking communication of the present invention through the wireless networking device of the present invention, referring to FIG. 1 , mainly includes the following steps:

Step S110: Detecting a preset function to determine a working mode corresponding to the function.

In one embodiment, the preset function may be preset in a function setting module of the wireless networking device. Among them, the functions include: networking mode, detection mode, and so on. A function can be preset, and when the MCU is powered on and starts to work, a mode corresponding to the function is detected, such as a networking mode or a detection mode, and the processing of the corresponding mode is executed.

For example, when the unit is powered on, the Zigbee coordinator installed on the outdoor unit is powered on synchronously. If it is a built-in wireless networking device, the USB power input module is also powered on from the Zigbee coordinator (power on), and the MCU Power on and start working; if it is an external wireless networking device, the USB power input module is powered by other power supplies such as the air conditioner external unit or the air conditioner indoor unit, and the MCU is powered on and starts to work.

Further, you can first set all indoor units of a set to the same group number through the DIP switch, and set the outdoor unit of this unit to be the same as all indoor units of the same group according to the group number of all indoor units of this unit. The group number is the same as the group number of the machine. In this way, when the unit is powered on, the Zigbee coordinator will set up the corresponding Zigbee wireless network of the outdoor unit. For example, the outdoor unit will send a networking request to the Zigbee coordinator, and the Zigbee coordinator will obtain the group number of the unit where the outdoor unit is located, etc. information, and confirm that the networking is successful, and realize the Zigbee wireless network networking of the outdoor unit. In this way, the same group number is assigned to the indoor units and outdoor units of the same unit, and the indoor units and outdoor units of multiple units in the same space area/location are classified in advance to avoid confusion.

Step S120: When it is determined that the working mode corresponding to the function is the networking mode, a signal for allowing all indoor unit modules to be networked is sent.

In one embodiment, in the networking mode, wireless networking between the indoor unit and the outdoor unit is required. Once the unit is powered on, the outdoor unit starts to work, and the Zigbee networking of the outdoor unit is completed as described above. When the networking mode is executed, the outdoor unit will obtain the instruction signal to join all indoor units in the same group, and broadcast the information that all indoor unit modules/nodes (that is, indoor units with routers) are allowed to join, or, through the indoor unit. The Zigbee coordinator searches for indoor units in the same spatial location/area.

Specifically, for example, when the wireless networking device is determined to be in the networking mode, the micro-control unit MCU (control unit) enters the operation of performing networking, and sends the information that joins all the indoor units in the same group to the outdoor unit through the communication interface of the outdoor unit module. command signal. The information that allows all indoor unit modules to join the network is broadcast by the indoor unit through the Zigbee coordinator or the Zigbee coordinator actively searches for the indoor unit modules belonging to the same group.

In another embodiment, in the networking mode, wireless networking between the indoor unit and the outdoor unit is required. Once the unit is powered on, the outdoor unit starts to work, and the Zigbee networking of the outdoor unit is completed as described above. When the networking mode is executed, the indoor unit will obtain the command signal that the outdoor unit module (that is, the outdoor unit with Zigbee coordinator) allows all the indoor unit modules of the same group to join. The Zigbee coordinator sends a networking request.

Specifically, for example, when the wireless networking device is determined to be in networking mode, the micro-control unit MCU (control unit) enters the operation of performing networking, and sends a corresponding outdoor unit module to the indoor unit through the communication interface of the indoor unit module A command signal that allows all indoor unit modules of the same group to be added to the network. When the indoor unit module receives the instruction signal, it sends a networking request to the corresponding outdoor unit module, and the request includes the group number.

Further, if there are multiple sets of units in the same space, the MCU can send an instruction signal to each outdoor unit module to allow all indoor unit modules to join, or it can send an instruction signal to all indoor unit modules to allow the addition of the corresponding outdoor unit module. , the outdoor unit module searches the indoor unit modules of the same group by itself, or all the indoor unit modules search for the corresponding outdoor unit modules to be added to the same group by themselves. Therefore, when the wireless networking device of the present invention performs the networking function, it can control the indoor and outdoor units of different groups to start networking by themselves, and no group will appear with the help of the respective group numbers and the information of the Zigbee coordinator. network or communication transmission errors.

Step S130: Determine whether the outdoor unit module detects the indoor unit module, if so, wait for the outdoor unit module and the detected indoor unit module to form a network and lock the networking information, wait until all the indoor unit modules are networked and lock the networking information end after.

In one embodiment, if the outdoor unit module detects the indoor unit module, for example, obtains the request of the indoor unit module and judges that the group numbers in the request are consistent, or searches for the indoor unit and determines that the group numbers are consistent, and notifies the detected The indoor unit module suspends sending requests or searching for outdoor units, indicating that networking is in progress. If multiple indoor unit modules are detected at this time, they will be notified in the order of detection. Further, when entering the stage of networking, it can indicate that the network is being formed, and assign the corresponding communication address and other information to the indoor unit modules with the same group number. Multiple indoor unit modules are assigned a unique set of units in the order of detection address for communication after networking. Further, after the address allocation of the networking is completed, the communication address and other information are sent to the corresponding indoor unit modules participating in the networking. When all the detected indoor unit modules have obtained their respective communication addresses, it is determined whether the outdoor unit is located. All the indoor units currently configured in the unit are added to the unit. If so, the networking information of the outdoor unit module and all indoor unit modules will be locked. If not, it means that some indoor units are not connected to the unit and will wait for the next networking.

For example, the MCU sends information through the communication interface of the outdoor unit module, and asks whether the outdoor unit module detects the networking request sent by the indoor unit module or whether the outdoor unit module searches for the indoor unit module. If so, the MCU controls the LED display module according to The T3 frequency flickers (that is, the timer T3 interrupt mode controls the LED flicker), indicating that it is in the state of networking. Further, when an indoor unit module is detected, the detected indoor unit module is also notified to suspend sending a request or search for an outdoor unit. Further, the outdoor unit assigns a unique communication address of each indoor unit to the detected indoor units in sequence. The wireless communication between the outdoor unit and all, part or individual indoor units in the unit is realized. The coordinator adds the communication address and group number to the networking response information and returns it to the corresponding indoor unit, so that the indoor unit also joins Zigbee coordination in the network formed by the device. Further, after all the detected indoor units obtain the networking response information, a feedback signal is sent to the MCU to indicate the end of the networking, and the MCU sends an instruction to lock the networking information of each indoor unit module and the corresponding outdoor unit module, such as the record in the outdoor unit module. The communication address, group number, and outdoor unit equipment information of the outdoor unit in the unit, as well as the communication address, group number, and outdoor unit equipment information of all indoor units that join the network. After the lock is completed, a feedback signal is sent to the MCU, and the MCU controls the LED display module to be in a steady state, indicating that the networking is completed, and the networking function ends.

Further, if the outdoor unit module does not detect the indoor unit module, the detection is continued until the indoor unit module is detected.

For step S120, when it is determined that the working mode corresponding to the function is the detection mode, the outdoor unit module and the indoor unit module enter the detection state.

The operation performed by it is still the same as the aforementioned step S120 to send a signal allowing all indoor unit modules to be networked. Specifically, the embodiments and examples are described in step S120.

Further, determine whether the outdoor unit module detects the indoor unit module, if not, continue to detect until the indoor unit module is detected; if so, enter the networking test state to test the networking of the outdoor unit module and the indoor unit module, and wait until it exceeds the predetermined time limit. After time, clear all connection information and prohibit other indoor unit modules from joining.

In one embodiment, if the outdoor unit module detects the indoor unit module, for example, obtains the request of the indoor unit module and judges that the group numbers in the request are consistent, or searches for the indoor unit and determines that the group numbers are consistent, and notifies the detected The indoor unit module suspends sending requests or searching for outdoor units, indicating that networking is in progress. If multiple indoor unit modules are detected at this time, they will be notified in the order of detection. Further, when entering the stage of networking, it can indicate that the network is being formed, and assign the corresponding communication address and other information to the indoor unit modules with the same group number. Multiple indoor unit modules are assigned a unique set of units in the order of detection address for communication after networking. Further, after the address allocation of the networking is completed, the communication address and other information are sent to the corresponding indoor unit modules participating in the networking. When all the detected indoor unit modules have obtained their respective communication addresses, it is determined whether the outdoor unit is located. All the indoor units currently configured in the unit are added to the unit. If so, the networking information of the outdoor unit module and all indoor unit modules will be locked. If not, it means that some indoor units are not connected to the unit and will wait for the next networking.

For example, the MCU sends information through the communication interface of the outdoor unit module, and asks whether the outdoor unit module detects the networking request sent by the indoor unit module or whether the outdoor unit module searches for the indoor unit module. If so, the MCU controls the LED display module according to T1S frequency flashes (the timer T1 interrupt mode controls LED flashing), indicating the tested indoor unit module and outdoor unit module (including indoor unit, outdoor unit, and the router on the indoor unit module, the coordinator of the outdoor unit module, etc.) Networking is in progress. Further, when an indoor unit module is detected, the detected indoor unit module is also notified to suspend sending a request or search for an outdoor unit. Further, the outdoor unit assigns a unique communication address of each indoor unit to the detected indoor units in sequence. The wireless communication between the outdoor unit and all, part or individual indoor units in the unit is realized. The coordinator adds the communication address and group number to the networking response information and returns it to the corresponding indoor unit, so that the indoor unit also joins Zigbee coordination in the network formed by the device. Further, after all the detected indoor units obtain the networking response information, a feedback signal is sent to the MCU to indicate the end of the networking, and the MCU sends an instruction to lock the networking information of each indoor unit module and the corresponding outdoor unit module, such as the record in the outdoor unit module. The communication address, group number, and outdoor unit equipment information of the outdoor unit in the unit, as well as the communication address, group number, and outdoor unit equipment information of all indoor units that join the network. Feedback signal to MCU after locking is completed.

Among them, the MCU will detect whether the flicker has timed out when it starts flickering at the T1S frequency. For example, a predetermined time length threshold T2 will be given. If it does not exceed, it will continue to monitor the time. If it exceeds, it means that the test networking time has passed, and the MCU will send an instruction Signal to the outdoor unit module. If there are multiple outdoor units, you can also send command signals to multiple outdoor unit modules, instructing to clear various networking connection information during the test networking, and no longer allow other indoor unit modules to join the test. Network detection The detection mode of each device in the network ends, and the LED display module turns off.

Therefore, it is possible to easily and quickly realize the active networking of the outdoor unit module and the indoor unit module through the independent wireless networking device dedicated to after-sales and production, execute the networking process and connect the new modules produced (indoor unit, indoor unit, indoor unit, etc.). outdoor unit, zigbee coordinator, router, etc.) for detection. In addition, the device has the function of displaying the networking status, and the LED display module displays which stage the networking is in, and its hardware design is simple and convenient, and the installation and use are simple, quick, and easy to use.

The networking device of the present invention will be further described below with reference to an example of the work flow of the networking device of the present invention shown in FIG. 5 .

When the unit is powered on, the wireless networking device connects to the 5V DC power supply through the USB power input module to supply power to the wireless networking device, and the MCU is powered on and starts to work. First detect which function is set in the function setting module, that is, the networking mode or the detection mode. As shown in Figure 5, it is determined whether the function setting module is set in the networking mode. If it is in the networking mode, enter the process on the left, and the MCU will send the outdoor unit module to allow all the indoor unit modules of the same group to be networked. , or to the indoor unit, the indoor unit finds the Zigbee coordinator of the unit to which it belongs, and broadcasts or sends a networking request. The MCU sends a query to each outdoor unit module to confirm whether the indoor unit module to be added to the network is detected. If not, it continues to wait for the detection of the added indoor unit module. If so, the MCU controls the LED display module/LED light to flash according to the T3 frequency. Indicates that it enters the networking state, and the indoor unit and outdoor unit realize Zigbee networking. When the networking is completed, the MCU will send an instruction to request the indoor and outdoor unit modules to lock the networking information, and control the LED light to be always on to end the networking function. Further, after the end, the wireless networking device can temporarily exit the control.

If it is the detection mode, it will enter the right process, and the MCU will send a signal to notify the indoor and outdoor unit modules to enter the detection mode. For each module test, the MCU will also send the outdoor unit module to allow all the indoor unit modules in the same group to form a network. To the indoor unit, the indoor unit finds the Zigbee coordinator of the unit to which it belongs and broadcasts or sends a networking request. The MCU sends a query to each outdoor unit module to confirm whether the indoor unit module to be added to the network is detected. If not, it continues to wait for the detection of the added indoor unit module. If so, the MCU controls the LED display module/LED light to flash according to the T1S frequency. Indicates that it enters the networking state, and the indoor unit and outdoor unit realize Zigbee networking. At the same time, the timer is used to monitor whether the flashing time exceeds T2. If not, it will continue to wait for the indoor and outdoor unit module networking. If it is, the MCU will consider that the module offline detection/test networking can be completed, and the MCU will send The command signal is sent to the outdoor unit module to clear all the connection information established by the network during the test, etc. At the same time, the outdoor unit module will no longer allow any other indoor unit modules to request to join the network. Turn off the LED light to end the detection function of the currently offline equipment (such as the indoor and outdoor units that implement wireless networking).

The implementation of the present invention will be further described below with reference to an embodiment of the air conditioner wireless networking communication system of the present invention shown in FIG. 4 .

Function detection module 410: Detect a preset function to determine a working mode corresponding to the function. The specific processing implementation manner is as described in step S110.

In one embodiment, the preset function may be preset in a function setting module of the wireless networking device. Among them, the functions include: networking mode, detection mode, and so on. A function can be preset, and when the MCU is powered on and starts to work, the mode corresponding to the function is detected, such as the networking mode or the detection mode, and the processing of the corresponding mode is executed.

For example, when the unit is powered on, the Zigbee coordinator installed on the outdoor unit is powered on synchronously. If it is a built-in wireless networking device, the USB power input module is also powered on from the Zigbee coordinator (power on), and the MCU Power on and start working; if it is an external wireless networking device, the USB power input module is powered by other power supplies such as the air conditioner external unit or the air conditioner indoor unit, and the MCU is powered on and starts to work.

Further, you can first set all indoor units of a set to the same group number through the DIP switch, and set the outdoor unit of this unit to be the same as all indoor units of the same group according to the group number of all indoor units of this unit. The group number is the same as the group number of the machine. In this way, when the unit is powered on, the Zigbee coordinator will set up the corresponding Zigbee wireless network of the outdoor unit. For example, the outdoor unit will send a networking request to the Zigbee coordinator, and the Zigbee coordinator will obtain the group number of the unit where the outdoor unit is located, etc. information, and confirm that the networking is successful, and realize the Zigbee wireless network networking of the outdoor unit. In this way, the same group number is assigned to the indoor units and outdoor units of the same unit, and the indoor units and outdoor units of multiple units in the same space area/location are classified in advance to avoid confusion.

Once the unit is powered on, the outdoor unit starts to work, and the Zigbee networking of the outdoor unit is completed as described above. When the networking mode is executed, the outdoor unit will obtain the instruction signal to join all indoor units in the same group, and broadcast the information that all indoor unit modules/nodes (that is, indoor units with routers) are allowed to join, or, through the indoor unit. The Zigbee coordinator searches for indoor units in the same spatial location/area.

Specifically, for example, when the wireless networking device is determined to be in the networking mode, the micro-control unit MCU (control unit) enters the operation of performing networking, and sends the information that joins all the indoor units in the same group to the outdoor unit through the communication interface of the outdoor unit module. command signal. The information that allows all indoor unit modules to join the network is broadcast by the indoor unit through the Zigbee coordinator or the Zigbee coordinator actively searches for the indoor unit modules belonging to the same group.

When the networking mode is executed, the indoor unit will obtain the command signal that the outdoor unit module (that is, the outdoor unit with Zigbee coordinator) allows all the indoor unit modules of the same group to join. The Zigbee coordinator sends a networking request.

Specifically, for example, when the wireless networking device is determined to be in networking mode, the micro-control unit MCU (control unit) enters the operation of performing networking, and sends a corresponding outdoor unit module to the indoor unit through the communication interface of the indoor unit module A command signal that allows all indoor unit modules of the same group to be added to the network. When the indoor unit module receives the instruction signal, it sends a networking request to the corresponding outdoor unit module, and the request includes the group number.

Further, if there are multiple sets of units in the same space, the MCU can send an instruction signal to each outdoor unit module to allow all indoor unit modules to join, or it can send an instruction signal to all indoor unit modules to allow the addition of the corresponding outdoor unit module. , the outdoor unit module searches the indoor unit modules of the same group by itself, or all the indoor unit modules search for the corresponding outdoor unit modules to be added to the same group by themselves. Therefore, when the wireless networking device of the present invention performs the networking function, it can control the indoor and outdoor units of different groups to start networking by themselves, and no group will appear with the help of the respective group numbers and the information of the Zigbee coordinator. network or communication transmission errors.

If multiple indoor unit modules are detected at this time, they will be notified in the order of detection. Further, when entering the stage of networking, it can indicate that the network is being formed, and assign the corresponding communication address and other information to the indoor unit modules with the same group number. Multiple indoor unit modules are assigned a unique set of units in the order of detection address for communication after networking. Further, after the address allocation of the networking is completed, the communication address and other information are sent to the corresponding indoor unit modules participating in the networking. When all the detected indoor unit modules have obtained their respective communication addresses, it is determined whether the outdoor unit is located. All the indoor units currently configured in the unit are added to the unit. If so, the networking information of the outdoor unit module and all indoor unit modules will be locked. If not, it means that some indoor units are not connected to the unit and will wait for the next networking.

For example, the MCU sends information through the communication interface of the outdoor unit module, and asks whether the outdoor unit module detects the networking request sent by the indoor unit module or whether the outdoor unit module searches for the indoor unit module. If so, the MCU controls the LED display module according to The T3 frequency flickers (that is, the timer T3 interrupt mode controls the LED flicker), indicating that it is in the state of networking. Further, when an indoor unit module is detected, the detected indoor unit module is also notified to suspend sending a request or search for an outdoor unit. Further, the outdoor unit assigns a unique communication address of each indoor unit to the detected indoor units in sequence. The wireless communication between the outdoor unit and all, part or individual indoor units in the unit is realized.
