[0002] The temperature controller is a device for directly controlling the driving of the load, and is widely used in systems such as air conditioners that require temperature adjustment. At present, the temperature controller on the market is usually in the mode of a single device corresponding to a single air conditioner. When multiple temperature controllers need to be linked, network communication of the devices such as 485 communication network is usually used for synchronous control to ensure that the states of the temperature controllers remain consistent. However, in actual application, once the 485 communication network fails or is disconnected, the communication between the temperature controllers will be interrupted, and the original linkage function cannot be continued. In this case, the temperature controllers cannot synchronize their states, which may cause the system to run unstably or fail.

[0003] The prior art cannot cope with the situation of failure of a device in the communication network. When the device communication fails, the temperature controllers in the system cannot continue to operate in linkage, and therefore, how to ensure the communication connection between the devices when a device in the 485 communication network fails has become a problem to be solved.

[0044] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0045] Figure 1 A flowchart of a control method of a device provided by an embodiment of the present application is shown in Figure 1 The method specifically includes the following steps.

[0046] S11, when a communication failure device is detected in a target network, determining whether there is a networked device in the target network, the target network including a plurality of devices connected to each other for communication.

[0047] The control method of the device provided by the embodiment of the present application is applied to a computer device, which can include but is not limited to a server, a desktop computer, a controller (for example, a programmable logic controller PLC), a central system, etc. The target network can be a communication network established based on the RS-485 standard, and the target network includes a plurality of devices that can be connected to each other for communication. The computer device can issue a control instruction to each device in the target network to control it. Specifically, when there is a communication failure device in the target network, the corresponding communication connection mode is determined according to whether there is a networked device in the current target network, so as to perform communication connection through the communication connection mode.

[0048] In this embodiment, the device can include but is not limited to a temperature control device (for example, a temperature controller, a thermostat, a temperature and humidity controller, etc.) that can be connected in the target network. Each device in the target network can transmit control instructions, device information, network configuration information, etc. to each other to realize linkage and message synchronization of all devices. When a device has a communication failure, the device cannot receive information transmitted by other devices, nor can it transmit information to other devices. Therefore, the way to determine whether there is a communication failure device currently can include that every interval of a preset time period, each device is controlled to transmit its own device information and network configuration information (only the networked device needs to transmit) to other devices. When a device cannot transmit or receive device information to or from other devices in a certain round of information transmission, it is determined that the device is a communication failure device. Alternatively, an RS-485 communication protocol analyzer or a serial port debugging tool can be used to monitor the data transmission of the devices in the network. By checking the reception and transmission of data packets, devices that do not respond or have incomplete data can be identified. If it is found that a device does not respond or data is lost, it is possible that the device has a communication failure. Error frames can be captured to check whether there is a CRC error, a check failure, etc. If so, it is determined that the device is a communication failure device. Alternatively, in the target network, the computer device can act as a master device, which usually communicates with a plurality of devices through polling. The polling request sent by the master device can be monitored by software, and it can be checked whether each device responds normally. If a device fails to return data or the response times out in polling, it is determined to be a communication failure device.

[0049] S12, determining a control strategy of the device in the target network according to the determination result.

[0050] S13, controlling a communication mode of the device in the target network according to the control strategy.

[0051] In the embodiment, the steps S12 and S13 are described uniformly. When the result of the judgment is that there is the network-configured device, it is determined that the control strategy is to control the non-network-configured device to connect with the router of the network-configured device, so as to control the communication connection of the device in the target network through the router, the first address of the network-configured device and the second address of the non-network-configured device.

[0052] Specifically, when the network configuration of any device is completed, the network configuration information is synchronously sent to each device through the target network to enable each device to store the network configuration information. The network configuration information can include the first address of the network-configured device and the information of the connected router. When the communication failure device occurs, it means that the device cannot be connected with other devices through the target network. Whether the network-configured device is the communication failure device or not, the communication connection between each device can be realized through the router. At this time, the current communication failure device can be determined by each device through the method of step S11. The non-network-configured device is controlled to determine the network configuration information of the network-configured device from the pre-stored network configuration information, and the network configuration is performed based on the network configuration information. The router connected with the network-configured device can be connected, and the non-network-configured device can be connected with the network-configured device through the router according to the pre-stored first address. The router can allocate a network address as a second address for the non-network-configured device. The non-network-configured device and the network-configured device can obtain and store the allocated second address, and the network-configured device can be connected with the non-network-configured device through the router according to the second address. The communication connection of the router can be performed only for the communication failure device, or the communication connection of the router can be performed for all non-network-configured devices.

[0053] For example, when the communication failure device is the non-network-configured device, the communication failure device is controlled to connect with the same router as the network-configured device. When there is a group control instruction or information that needs to be synchronized, the communication failure device can receive the information or control instruction forwarded by the network-configured device, and other communication normal devices can also communicate in the target network. When the communication failure device is the network-configured device, any communication normal device in the other devices is controlled to connect with the same router as the communication failure device. When there is a group control instruction or information that needs to be synchronized, the communication failure device can receive the information or control instruction forwarded by the communication normal device through the router, and other communication normal devices can also communicate in the target network. Alternatively, all the other devices are controlled to connect with the same router as the communication failure device, and the sending of messages and control instructions is realized through the router. In this way, all the devices in the target network can realize the communication connection with each other.

[0054] When the result of the judgment is that there is no network-configured device, the control strategy is determined as: controlling the communication-faulty device to open a hotspot, and controlling the communication-normal device in the target network to communicate with the communication-faulty device through the hotspot.

[0055] Specifically, when there is no network-configured device in the target network, the communication-faulty device automatically opens the wireless hotspot function, at this time, the communication-faulty device generates a temporary wireless hotspot signal, so that other communication-normal devices in the target network can discover and connect to the hotspot.

[0056] Specifically, the device information synchronized by the devices in the target network every interval of the preset time length contains the hotspot name of each device, that is, each device will pre-store the hotspot name of other devices, the communication-normal device in the target network is controlled to scan the available network nearby, and after discovering the hotspot name opened by the communication-faulty device, the communication-normal device is controlled to automatically connect to the hotspot to establish a temporary communication channel with the communication-faulty device.

[0057] Data interaction and state synchronization can be performed through the hotspot of the communication-faulty device. Even if the communication-faulty device cannot access the target network, other devices can still perform linkage control through the temporary communication mode.

[0058] In one possible implementation, the connection state of the communication-faulty device can be continuously monitored, when the fault device re-recovers normal communication with the router or the target network, the hotspot function of the device can be controlled to be closed, and the normal network communication path is restored. At the same time, the communication-normal device that has established a connection through the hotspot will automatically switch back to the original network connection, realizing seamless communication.

[0059] The device control method provided by the embodiment of the application can determine the control strategy according to whether there is a network-configured device in the target network when it is detected that there is a communication-faulty device in the target network, the target network contains a plurality of devices that are communicatively connected with each other, control the communication mode of the devices in the target network according to the control strategy. Therefore, when there is a communication-faulty device in the target network, the corresponding control strategy can be determined according to whether there is a network-configured device in the current target network, the communication mode of the device is controlled through the control strategy, the communication network can still normally communicate and connect when a certain device appears communication fault, the information transmission between devices is ensured, and the out-of-control of the system is avoided.

[0060] Figure 2 Another flowchart of the device control method provided by the embodiment of the application is shown in FIG. 2, and the method specifically includes the following steps. Figure 2

[0061] ​S21, every interval of a first time length, control each device in the target network to send device information to other devices; when more than a preset number of devices do not receive the device information of a first device, determine that there is a communication failure device, and determine that the first device is the communication failure device.

[0062] In this embodiment, every interval of a preset first time length, each device in the target network sends the current device information of the device to all other devices once, to realize timely device information synchronization. The device information can include but is not limited to: device identification, communication address, device self-bar code information, device hotspot name, etc. When each device receives the device information sent by other devices, all device information is stored for subsequent communication.

[0063] After sending the device information once, when more than a preset number of devices in the target network do not receive the device information of a first device, it means that the first device cannot communicate in the target network, and the first device is determined to be a communication failure device. At this time, each device will receive the message that the first device is a communication failure device.

[0064] At the same time, when a second device does not receive the device information sent by any other device, it is determined that there is a communication failure device, and the second device is determined to be a communication failure device. That is, when a second device cannot receive the device information sent by other devices, the second device can determine itself to be a communication failure device. Therefore, when there is a communication failure device in the target network, all devices can timely obtain the message of which device is the communication failure device.

[0065] S22, when there is a networked device, when the networked device is connected to the router, control the networked device to send network configuration information to the non-networked device; control the non-networked device to connect to the router through the network configuration information; control the non-networked device to extract a first address from the device information of the networked device to communicate and connect with the networked device through the first address.

[0066] In this embodiment, after the device in the target network is connected to the router for network configuration and is completed, the networked device sends its own network configuration information to each other device, so that each device stores the network configuration information of the networked device. The network configuration information is used for connecting the router for network configuration, and can include but is not limited to: router name, password, address, etc.

[0067] Further, when it is determined that the communication failure device exists and the currently existing device has been configured, it is not necessary to determine whether the communication failure device is the configured device, and the unconfigured device can be controlled to connect to the router of the configured device according to the configuration information, so that all devices are connected to the same router and are connected through the router, and the unconfigured device can determine the device information of the configured device from the stored device information, extract the first address of the configured device, and send a message to the configured device through the router according to the first address. The configured device can also forward the received message to other devices, so that all devices in the target network are connected.

[0068] S23, control the unconfigured device to send the second address to the router, so that the router sends the second address to the configured device, so that the configured device is connected to the unconfigured device through the second address.

[0069] In this embodiment, after the unconfigured device is connected to the router, the router can allocate a second address to the unconfigured device, or the unconfigured device sends the second address carried by itself to the router, and the router sends the second address to the configured device or other devices connected to the router, so that the configured device or other devices can send a message to the unconfigured device through the router according to the second address.

[0070] In one possible implementation, when the configured device is multiple and the multiple configured devices include the communication failure device, the first target router connected by the communication failure device is determined; the communication normal device is controlled to connect to the first target router according to the configuration information of the communication failure device, and the devices in the target network are controlled to be connected through the first target router, the third address of the communication failure device and the fourth address of the communication normal device.

[0071] In the embodiment, when there are multiple network-configured devices, it is judged whether the communication failure device is a network-configured device, and when the result of the judgment is yes, it is determined that the router currently connected by the communication failure device is the first target router, and other communication normal devices or other non-network-configured communication normal devices are controlled to connect the first target router according to the pre-stored network configuration information, so as to realize the communication connection among all devices through the first target router. The third address of the communication failure device in the first target router can be sent to other devices connected to the first target router, so that all devices can communicate with the communication failure device through the third address. Meanwhile, the first target router can forward the fourth address of the received communication normal device and send it to the communication failure device for storage, so that the communication failure device can communicate with the communication normal device according to the fourth address through the first target router. Any communication normal device connected to the first target router can receive the message of the communication failure device and forward it to other devices through the target network, that is, as long as the communication connection between the communication failure device and any communication normal device is established through the first target router, the communication normal device can realize the communication connection of all devices through the target network and the first target router.

[0072] In one possible implementation, when the network-configured devices are multiple and the communication failure device is not included in the multiple network-configured devices, the communication failure device is controlled to acquire the router signal strength of each network-configured device; a target network-configured device with the maximum router signal strength is determined, and a second target router of the target network-configured device is determined; the communication failure device is controlled to connect the second target router according to the network configuration information of the target network-configured device, and the devices in the target network are controlled to communicate through the third address of the communication failure device and the fifth address of the target network-configured device through the second target router.

[0073] In the embodiment, when there are multiple network-configured devices, it is determined whether the communication failure device is a network-configured device. When the determination result is no, the communication failure device needs to connect the router of the network-configured device. At this time, the router signal strength of all routers that can be searched is obtained, the device with the maximum router signal strength is determined as the target network-configured device of the to-be-connected router, the router of the target network-configured device is determined as the second target router, the communication failure device is controlled to connect the second target router through the pre-stored network configuration information, after the connection is successful, the second target router can allocate a third address to the communication failure device, or the communication failure device sends its third address to the second target router, so that the second target router sends the third address to the target network-configured device, so that the target network-configured device can send a message to the communication failure device through the second target router according to the third address, and the second target router sends a fifth address of the target network-configured device to the communication failure device, so that the communication failure device can send a message to the target network-configured device through the second target router according to the fifth address. At the same time, the target network-configured device can forward the message of the communication failure device to other devices through the target network, thereby realizing the communication connection between all devices.

[0074] S24, when there is no network-configured device, the communication failure device is controlled to start a hotspot, and the communication normal device is controlled to extract the hotspot name from the communication failure device information; the communication normal device is controlled to connect the hotspot according to the hotspot name, so as to send the verification information to the communication failure device through the hotspot; when the verification is successful through the verification information, the communication failure device and the communication normal device are controlled to establish a communication connection according to the hotspot.

[0075] In the embodiment, when there is no network-configured device in the target network, the communication failure device is controlled to start a hotspot. At this time, if there is only one hotspot, the communication normal device can directly connect the hotspot to realize temporary communication between devices. Among them, only one communication normal device can be controlled to connect the hotspot. When the communication normal device receives the message sent by the communication failure device, the message can be forwarded to other devices through the target network. Thus, the number of hotspot connections can be reduced, and the processing pressure can be reduced. Each communication normal device can also be controlled to communicate with the communication failure device through the hotspot, so that each communication normal device can timely receive the message of the communication failure device.

[0076] When multiple hotspots are included, each communication normal device can search for the device information of the communication failure device from the stored device information, and extract the hotspot name therefrom to search for the hotspot of the communication failure device for connection.

[0077] Further, after successfully connecting to the hotspot, the communication normal device first sends a verification information to the communication failure device. The verification information can include, but is not limited to, the identity authentication of the device, the verification code or the key parameters of the communication between the two parties, to ensure the safety of the connection between the devices and the accurate transmission of data. After receiving the verification information, the communication failure device verifies it. The verification process includes confirming the identity and state of the communication normal device. If the verification information is verified successfully, the communication failure device will send a verification confirmation information to the communication normal device. When the verification confirmation information is received by the communication normal device, the communication connection between the two devices is formally established through the hotspot. At this time, the communication normal device and the communication failure device can exchange data and synchronize the state through the temporary communication path.

[0078] S25, generating failure information according to the communication failure device; sending the failure information to each device in the target network for display; when the communication failure device still does not recover to the normal state after the second time interval, controlling the communication failure device to disconnect from the target network.

[0079] In this embodiment, when the communication connection is established, the failure information containing the related information of the communication failure device is generated, which can include, but is not limited to, the name and unique identifier of the communication failure device, the time of the failure occurrence, the type of the failure (such as communication interruption, network timeout, etc.), the possible cause of the failure (such as insufficient signal coverage, network interruption, hardware failure, etc.), etc. The system sends the generated failure information to all communication normal devices in the target network through the established communication connection. Each device receiving the failure information can use it for display to prompt the user that there is a communication failure device in the current network. The second time interval is used to wait for the automatic recovery of the communication failure device. If the communication failure device successfully recovers the connection with the target network after the second time interval, the failure information is updated to all devices to inform other devices that the failure has been resolved and the device has returned to normal work. If the communication failure device still does not recover the normal connection after the end of the second time interval, the state of the communication failure device is detected again to confirm that it cannot recover the communication, and the communication failure device is controlled to disconnect from the target network (for example, forcibly logging out the device, clearing the network information of the device or marking it as an unusable device, etc.) to prevent the failure device from affecting other normally running devices. At the same time, after the communication failure device is disconnected from the target network, the updated failure information is sent to other devices in the network again to prompt that the device has been forcibly disconnected. Other devices can adjust their linkage operations or notify the user to handle the problem according to this information.

[0080] As an example, as shown in FIG. 6, the communication failure device 601 is connected to the hotspot 602, and the communication normal device 603 is connected to the hotspot 604. The communication normal device 603 sends a verification information to the communication failure device 601. After receiving the verification information, the communication failure device 601 verifies it. If the verification information is verified successfully, the communication failure device 601 sends a verification confirmation information to the communication normal device 603. When the verification confirmation information is received by the communication normal device 603, the communication connection between the two devices is formally established through the hotspot. At this time, the communication normal device 603 and the communication failure device 601 can exchange data and synchronize the state through the temporary communication path. Figure 5Fig. 1 is a flow diagram of a control method of a device according to an embodiment of the present application, the target network is a 485 network, and the device is a temperature controller. After each temperature controller is powered on, it can communicate through the 485 network. Each temperature controller synchronizes device information such as device identification and hotspot information with each other for storage. When any temperature controller successfully configures the network or the network configuration information changes, the temperature controller synchronizes the network configuration information with other temperature controllers through the 485 network. Each temperature controller can obtain the network configuration information of the currently configured device.

[0081] When a temperature controller fails, the temperature controller address point in the 485 network is checked continuously. The absence of data of a temperature controller can determine that a specific temperature controller has been offline, i.e., a communication failure device. Meanwhile, the offline temperature controller itself can also confirm that it has been offline through the method. When there is a configured temperature controller, the unconfigured temperature controller connects the same route as the configured temperature controller through the route information obtained when the communication is normal, and communicates with the configured temperature controller according to the address obtained in the 485 network. At this time, the broadcast (group control) control of the temperature controller command can be implemented. When the unconfigured temperature controller successfully communicates, the temperature controller publishes its own address to the configured temperature controller. At this time, the addresses of the configured temperature controller and the unconfigured temperature controller are known, and the data synchronization between the temperature controllers can be achieved.

[0082] If there is no configured temperature controller, temporary communication is achieved through the way of opening a hotspot of the WiFi network. When a temperature controller is detected to be offline or to fail on the 485 network, the offline temperature controller opens a hotspot. The normally communicating temperature controller searches the backup module hotspot name when the communication is normal. When the corresponding hotspot is found, the temperature controller tries to connect first. If the connection is successful, the temperature controller information of the temperature controller is checked to determine whether it is the offline temperature controller. If it is confirmed to be the offline temperature controller, the temporary communication network is successfully established.

[0083] If there are multiple configured temperature controllers, the route connected by the offline temperature controller is the main route. The normally configured temperature controllers and the temperature controllers not in the configured relationship connect the route connected by the offline temperature controller. After the connection is successful, the communication is performed. When the temporary communication network is successfully established, the user is prompted that the current communication has failed. At this time, it is temporary communication, and the temperature controller number of the offline temperature controller is displayed. The user is reminded that the current temperature controller state is not normal and needs to be repaired in time. After the temporary communication network is established, the temperature controller starts timing. When the temperature controller runs for more than 72 hours and the failure still exists, the network communication is stopped, and the original unconfigured temperature controller is disconnected from the route or hotspot connected for temporary communication. In the temperature controller, it is displayed that the maximum time of the temporary communication has been reached, and the 485 network needs to be maintained in time.

[0084] The control method of the device provided by the embodiment of the application can realize the communication connection of the device in different communication modes according to whether there is a network configuration device at present and whether the network configuration device contains a communication failure device when the communication failure device exists in the target network. The original communication function can still be normally used for a period of time when the communication failure device exists in the target network, and temporary communication is realized. When there is a network configuration device, the communication connection is realized through the router of the network configuration device, and when there is no network configuration device, the communication connection is realized through the hot spot of the communication failure device and other devices, and the safe communication is ensured through the verification mechanism. When the failure device is not restored to the normal state for a long time, the system generates failure information and broadcasts it to all devices for display, prompting the user of the failure condition. Meanwhile, the system automatically disconnects the failure device that cannot be restored after a predetermined time interval, avoiding affecting the normal operation of other devices. The stability, automation and reliability of the system can be effectively improved, the user intervention is reduced, and the network resource management is optimized.
