Taking AT89C51 single chip microcomputer system as the core, the real-time inspection of multi-point temperature can be carried out. The detection unit (slave) can independently function at the same time, according to the master machine instructions are collected on the temperature measurement results, not only in the local, but also can use the microcontroller serial port, through the RS-232 bus communication protocol and the data collected will be transmitted to the host computer, and further processing of the archive. The main control machine is responsible for the transmission of control commands, control the temperature acquisition of each slave, collect measurement data, and collate, display and store the measurement results (including historical data). The main controller and the slave machine can be connected and coordinated with each other, so as to achieve the overall unity and harmony of the system.
