This invention belongs to the field of RS485 wired communication technology, specifically relating to a data conflict communication method based on RS485 communication in automatic measurement. This invention aims to solve the problem that when the RRU polls data from the MCU on the PPA board, the MCU on the PA board always returns a packet within a fixed time frame, while the RS485 packet return time is unpredictable, leading to unstable data transmission. This invention provides a data conflict communication method based on RS485 communication in automatic measurement. Specifically, the MCU on the PA board periodically collects the initial data of the data packet through a main loop function and saves this data in a global variable. It periodically updates the collected initial data and saves it to the global variable, determining if there is a serial port interrupt. When the MCU on the PA board receives a data packet from the RRU via a serial port interrupt, it determines whether the data packet is a polling packet through protocol parsing. In the main loop task, the global variable flag is checked to ensure that the RS485 data bus is not disrupted by delayed data packets, thus providing a data conflict communication method based on RS485 communication in automatic measurement.
