DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Figure 1 Schematic diagram of the structure of the communication control device of the air conditioner controller provided by the present invention. Figure 1 As shown, the device includes a first bus device and a second bus device connected based on a communication bus, wherein: The first bus device detects whether the communication bus is in an idle state, and based on the communication bus being in the idle state, sends first control data to the communication bus, detects the communication bus, obtains second control data, and verifies whether the second control data is consistent with the first control data, and determines that the data is sent correctly based on the verification consistency; The second bus device obtains the corresponding first control data based on the communication bus, and executes the corresponding control instruction according to the first control data.

[0022] In an optional embodiment, before the first bus device detects whether the communication bus is in an idle state, the process includes: the first bus device sends communication data to the second bus device based on the communication bus; the second bus device receives the communication data and returns communication response information to the first bus device; and the first bus device receives the communication response information and determines that communication with the second bus device is normal.

[0023] It should be added that reference Figure 2 The first bus device includes a first control module, a first communication module and a second communication module, and the second bus device includes a second control module, a third communication module and a fourth communication module.

[0024] It should be noted that the first bus device and the second bus device are respectively configured with corresponding device types and device addresses, so that when communicating, the corresponding bus device can be locked based on the device type and device address, so that in the case of multiple connections, the target second bus device can accurately receive the control data sent by the first bus device, improve communication efficiency, and make the interaction between the first bus device and the second bus device faster and smoother. For example, the device type of the first bus device is A and the device address is 1, and the device type of the second bus device is B and the device address is 1.

[0025] Correspondingly, the first bus device sends communication data to the second bus device based on the communication bus, including: the first control module sends the communication data to the first communication module; the first communication module sends the communication data to the communication bus.

[0026] In addition, the second bus device receives communication data and returns communication response information to the first bus device, including: the third communication module detects the communication bus, obtains corresponding communication data, and sends the communication data to the second control module; the second control module generates communication response information based on the received communication data, and sends the communication response information to the third communication module; the third communication module sends the communication response information to the communication bus.

[0027] In addition, the first bus device receives the communication response information and determines that the communication with the second bus device is normal, including: the first communication module detects the communication bus, obtains the corresponding communication response information, and sends the communication response information to the first control module.

[0028] In this embodiment, the first control module controls the first communication module to detect whether the communication bus is in an idle state, including: the first control module sends a first idle state detection instruction to the first communication module; the first communication module detects the communication bus based on the first idle state detection instruction, and sends the detection result to the first control module; the first control module determines that the communication bus is in an idle state based on the fact that no communication information is detected in the detection result within the first target time.

[0029] It should be added that the first target time can be determined according to the actual bus occupancy. For example, if there is no communication on the communication bus for 50 ms continuously, the bus can be considered idle. Then the first target time can be set to 50 ms. No further limitation is made here. In addition, when the first control module sends the first idle state detection instruction to the first communication module based on the device address of the second bus device obtained earlier, the first control module determines the number of devices of the second bus device based on the device address of the second bus device obtained when it is powered on first, and sends the corresponding first control data according to the corresponding device address. The first control data may include the device address of the control data to be received, the device type, and the control information to be sent.

[0030] Specifically, the first bus device sends the first control data to the communication bus, detects the communication bus, obtains the second control data, and verifies whether the second control data is consistent with the first control data, including: the first control module, based on the device address of the second bus device obtained previously, sends the first control data to the first communication module; the first communication module sends the first control data to the communication bus; the second communication module detects the communication bus, obtains the second control data, and sends the second control data to the first control module; the first control module verifies whether the second control data is consistent with the first control data.

[0031] It should be noted that the first communication module and the second communication module can use a 485 chip, which is an interface chip that implements the RS-485 communication standard. Since the 485 chip is in the state of sending data, the reception is in an interrupted state, so it is necessary to detect the communication bus through the second communication module to determine whether the data sent to the communication bus by the first bus device is consistent with the data of the detected communication bus, so as to ensure the correctness of the data and avoid the situation where data transmission errors are caused by bus code conflicts.

[0032] Specifically, the first control module verifies whether the second control data is consistent with the first control data, and also includes: the first control module determines the bus code conflict based on the verification that the second control data is inconsistent with the first control data, and controls the first communication module to re-detect whether the communication bus is in an idle state, and based on the communication bus being in an idle state, controls the first communication module to re-send the first control data to the communication bus according to a preset delayed sending strategy; wherein the preset delayed sending strategy is used to limit the delay in sending to the corresponding second bus device; the second bus device, based on the delay limited by the preset delay strategy, re-acquires the corresponding first control data from the communication bus, and executes the corresponding control instruction according to the first control data.

[0033] It should be noted that the detection of whether the communication bus is in an idle state can refer to the above description of the first control module, controlling the first communication module, and detecting whether the communication bus is in an idle state, which will not be repeated here. In addition, the preset delayed sending strategy includes a first strategy and a second strategy, the first strategy is used to limit the second bus device receiving data to one time delay of 0, and the second strategy is used to limit the second bus device receiving data to at least two times, based on the device type and device address of the corresponding second bus device, the delay of the corresponding second bus device is determined, and the first bus device sends the corresponding data through the preset delayed sending strategy to reduce the probability of communication data errors.

[0034] Furthermore, latency = (device type + device address × target value).

[0035] Furthermore, the delay unit determined according to the device type and device address of the second bus device to receive the first control data can be controlled in milliseconds, and the target value can be set according to the actual delay sending requirements, such as 10, which is not further limited here.

[0036] In an optional embodiment, the second bus device includes a second control module and a third communication module. After the second bus device executes the corresponding control instruction according to the first control data, it also includes: the second control module sends a second idle state judgment instruction to the third communication module; the third communication module detects the communication bus based on the second idle state judgment instruction, and sends the detection result to the second control module; the second control module determines that the communication bus is in an idle state based on the monitoring result within the second target time that no communication information is detected, and controls the third communication module to send the instruction execution result to the communication bus according to a preset delayed sending strategy; the first communication module obtains the corresponding instruction execution result from the communication bus based on the delay specified by the preset delay strategy, and sends the obtained instruction execution result to the first control module.

[0037] It is worth noting that the second bus device also includes a fourth communication module. When the second bus device needs to send corresponding control data to the first bus device, the first bus device can send corresponding first control data to the second bus device, which will not be repeated here. In addition, the second target time can be set with reference to the first target time, which will not be repeated here.

[0038] In an optional embodiment, the first bus device is an indoor unit, and the second bus device is a wired controller; or, the first bus device is a wired controller, and the second bus device is an indoor unit.

[0039] In an optional embodiment, in order to avoid a long period of no control data being sent and to avoid misjudging communication abnormalities, the wire controller detects whether the communication bus is idle within a fourth target time based on the fact that no control data is sent or received within the third target time, and initiates communication with the indoor unit based on the communication bus based on the fact that the communication bus is idle within the fourth target time. It should be added that the fourth target time can be set according to the actual frequency of sending control data and the time threshold for misjudging communication abnormalities, such as 1 minute, which is not further limited here.

[0040] In an alternative embodiment, reference Figure 3The wire controller includes a master wire controller and at least one slave wire controller. When the number of indoor units is at least two, the indoor units are connected to the master wire controller through a communication bus, and the slave wire controller is connected to the master wire controller. Accordingly, the master wire controller and the slave wire controller establish communication. In the event of a communication failure with the master wire controller, the slave wire controller takes over the communication with the indoor unit or the control of the indoor unit, so as to avoid the situation where the whole system is paralyzed due to a failure of the master wire controller.

[0041] In summary, the embodiment of the present invention sends data only after the first bus device detects whether the communication bus is in an idle state, and transmits data in time when the bus is idle, thereby reducing waiting time, avoiding bus conflicts, and ensuring that bus resources are reasonably used. After sending the data, the communication bus is detected to obtain the second control data to verify whether it is consistent with the first control data sent by itself, thereby effectively ensuring the accuracy of the data during the transmission process and avoiding inaccurate data transmission caused by bus code conflicts. The first bus device ensures accurate data transmission, and the second bus device responds to and executes control instructions in a timely manner, thereby making the entire communication process smooth and efficient, improving system operation efficiency and stability, and improving the maintainability and extensibility of the system.
