PC and microcontroller AT89C51 using up a meter automatic error handling system

Meter as a measuring tool in the production and use of its measurement accuracy is required during testing, the authors use PC and MCU AT89C51 constitute a meter automatic error handling system, which can simultaneously detect multiple meter, and of the measured data are processed, with automatic and efficient features. 2 System Components meter  mcb circuit breaker  handling system consists of a host (PC machines) and multiple testing machine (AT89C51) linked together in serial communication, the network structure. The host is responsible Circuit breaker , command input, test data processing, electri cenergy meter , data query and report printing. Detector sent to the receiving host various parameters and commands sent by the host command and press work, automatic detection, and detection of data back to the host.
