Design of Multi-computer Communication Program and Menu in Distributed Temperature Measurement System

The distributed temperature measurement system consists of computer management station and many monitoring stations. This paper describes configuration of multi-computer communication circuit and communication protocol format. Communication program design of receiving data is expounded. Specific process for serial port interrupt service program is analyzed and illustrated. The flow chart is given out. The realization idea of multi-computer communication is studied and analyzed. The function jump can be realized through comparing monitoring station’s address by use of communication protocol. Computer management station can transfer and amend alarm upper limit for appointed room. The menu design of management station is realized by VB. Program design and communication control definition are completed. The menu of transferring alarm upper limit from management station is designed. The communication data exchange can be realized in distributed temperature measurement system. Real time temperature inspection and alarm for many rooms are accomplished. The management of multi-computer communication is realized.
