Design of embedded multi-machine asynchronous communication system based on single-chip computer control

Existing multi-computer asynchronous communication systems have low rate, large loss and time consumption, so an embedded multi-computer asynchronous communication system based on chip control is proposed and designed. Based on single chip control module as the center, connect interface circuit, power supply to data analysis. AT89S51 single chip is used to build the control module, the interface is used to connect the computer, the power module uses low noise low voltage differential linear voltage stabilizer. In software section, design the communication protocol of host query and slave interruption, receive the host command from the machine and complete the address matching and transmit data to the host and query the MCU until all communication data are received, thus completing the system design. The experimental results show that the average of the communication transmission rate is 1151Mb/s, the high diversity gain, small loss, and the operation time consumption is much lower than the traditional communication system.
