Industrial control flow collector B code time synchronization system and method

The invention discloses an industrial control flow collector B code time synchronization system and method, and relates to the technical field of industrial control computer communication. The system comprises a CPU, a logic processing chip, a network chip, a microprocessor, an RS485 chip and a B code generator. The B code time synchronization system adopts a double-path redundancy design, the B code time synchronization system decodes B code data, and a B code generator sends the decoded B code data; an autonomous and controllable software and hardware platform is adopted, all components adopt domestic chips, the RS485 isolation circuit is optimally designed, so that B code data receiving is more stable, the anti-interference capability is high, the microprocessor adopts a two-way redundancy design of decoding of GD32F103 and a special decoding module, and the cost is low. According to the B code time synchronization system, a logic processing chip is used for monitoring and arbitrating the whole B code time
