摘要：

A distributed data acquisition system based on multi- computer communication among Single-chip Microcomputers is proposed in this paper. The AT89S52 is used as the control core, and multi- computer communication is realized by bus RS485. The hardware construction of the system is introduced. Circuits of each module including the microcomputer, temperature sensor, communication interface and voice alarming are designed. Process of multi- computer communication is described. Programs of master serial transmission and slave serial receiving are written and compiled. Experiments are conducted on temperature measure and acquisition. The results show that a satisfied effectiveness is obtained. A reliable performance can be achieved.
