Abstract

According to disadvantages of wired transmission system in grain depot temperature test equipment, we design a distributed grain depot temperature monitor and control system based on wireless communication technology and single chip microprocessor technology, etc. Field slave computer realizes each grain depot condition temperature signal collection through 1-wire bus digital temperature sensor DS18B20. Single chip microprocessor MSP430F149 processes monitor signal and drives temperature control equipment to realize constant temperature control. Based on wireless transceiver chip nRF905, system can complete collection signal wireless communicate from grain depot monitor equipment to central computer, and central computer controller connects with upper PC by serial interface RS-232, which the distributed grain depot monitor and control system is carried out. This paper mainly introduces systempsilas structure, hardware and software design in detail.
