The communication module in the embodiment of the invention can be a certain communication module in a tested product, such as a communication module in an air conditioner, and can be used for testing whether the performance of the product is normal or not; the analysis module can be upper computer software, one upper computer can comprise a plurality of upper computer software, each upper computer software corresponds to one communication module, when the communication interfaces of the upper computers are connected with different communication modules, the communication interfaces of the upper computers are in communication connection with the upper computer software corresponding to the communication modules, when products are detected, parameters of the products in operation are sent to the upper computer software through the communication interfaces of the upper computers, the upper computer software processes the received parameters to obtain parameter curves or determines control instructions according to the received parameters, and then the control instructions are sent to the main controller.
The communication interface in the embodiment of the invention may be a UART (Universal Asynchronous Receiver/Transmitter, universal asynchronous receiver Transmitter) interface, and when the communication module is inserted into the UART interface, the controller may obtain the baud rate parameter of the communication module, that is, the second baud rate parameter, through the UART interface.
The controller in the embodiment of the invention can be an MCU (Microcontroller Unit, micro control unit), each UART interface is connected with one pin or a plurality of pins of the MCU, and in the embodiment of the invention, the MCU controls the target analysis module to establish communication connection with the communication interface, namely, the target analysis module establishes communication connection with the pin connected with the communication interface of the MCU.
In a specific implementation, the controller may acquire the baud rate parameter of the communication module connected to the communication interface through the communication interface, that is, the second baud rate parameter, and the controller stores the acquired second baud rate parameter in the memory, and then receives preset data for calculating the baud rate parameter sent by the communication module.
After the controller receives the preset data, the preset data can be calculated according to a preset algorithm to obtain a first baud rate parameter. Specifically, the length of the low pulse may be detected according to a data transmission protocol of preset data, so as to calculate and obtain the first baud rate parameter.

Specifically, when the first bit rate parameter and the second bit rate parameter are compared, an analysis module corresponding to the first bit rate parameter with the same comparison result is taken as a target analysis module.
For example, as shown in fig. 2, the upper computer includes n analysis modules, each analysis module sends preset data to the controller 20, the preset data are respectively corresponding to preset data 1, preset data 2 and … …, preset data a … … (n-1) and preset data n, after the controller 20 receives the n preset data, each preset data is calculated according to a preset algorithm to obtain n first baud rate parameters, and meanwhile, the controller 20 obtains the baud rate parameters of the communication module, that is, second baud rate parameters, through the communication interface 10, and compares the second baud rate parameters with each calculated first baud rate parameter, and uses the analysis module corresponding to the first baud rate parameter with the same comparison result as the target analysis module.

If there are multiple target analysis modules, after the controller sends first response data to the multiple target analysis modules, a handshake data packet is sent to the controller 20 according to a preset communication protocol, after the controller 20 receives the handshake data packet sent by the multiple target analysis modules, the handshake data packet is compared with a data packet corresponding to the communication module, and second response data is sent to the target analysis module with the same comparison result, namely, the communication connection between the target analysis module with the same comparison result and the communication interface is controlled.

For example, as shown in fig. 3, 3 target analysis modules are determined by the controller, and the target analysis modules are respectively a target analysis module 1, a target analysis module 2 and a target analysis module 3, after each target analysis module receives first response data, handshake data packets are respectively sent to the controller according to a preset communication protocol of the controller, after the controller receives three handshake data packets, the controller compares the received three handshake data packets with data packets corresponding to the communication module, and the comparison result is that the handshake data packets sent by the target analysis module 2 are identical to the data packets corresponding to the communication module, then the controller sends second response data to the target analysis module 2, and the target analysis module 2 is controlled to establish communication connection with the communication interface.
The data packet corresponding to the handshake data packet and the communication module in the embodiment of the invention can comprise packet header, command word, data length, checksum and other information; the second response data is response data corresponding to a protocol format of the communication protocol.
In a specific implementation, a target analysis module is determined, and in order to further determine that the target analysis module is a target analysis module corresponding to the communication module, the target analysis module may be reconfirmed by adopting a manner of sending handshake data packets.
Specifically, the controller sends first response data to the target analysis module, after the target analysis module receives the first response data, the controller sends a handshake data packet to the controller according to a preset communication protocol, after the controller receives the handshake data packet, the controller compares the handshake data packet with a data packet corresponding to the communication module, and if the comparison result is the same, the controller sends second response data corresponding to the preset communication protocol to the target analysis module, so that communication connection between the target analysis module and the communication interface is established.
