A Study on Multi-spots Temperature Measurement System Based on 89C51

摘要：

Taking AT89C51 SCM as the core, real-time multi-point temperature scan test was achieved. Every detection unit (slave processor) could independently accomplish its functions, and according to the instructions master controller collected regularly the temperature. Measurement not only was shown at the local, but also could make use of SCM serial interface through RS-485 bus and communication protocol master machine collecting data transmission, further filing, processing. Master controller was responsible for the control of command transmission, the control of each slave processor carried on temperature gathering, the collection of survey data, and the reduction, the demonstration and the memory of the measurement result (included historical data). Master controller and every slave processor tied mutually and coordinated to achieve unity and harmony results.
