Remote data acquisition has been applied in industry, agriculture, education and medical field, especially in the work, the agricultural environment monitoring has high application value, and also for the people brought great convenience.
This design by monolithic integrated circuit AT89S52 as microprocessors, terminal nodes through temperature sensor, humidity sensors and pressure sensor, the acquisition of temperature, humidity and pressure signal after adjusting circuit, through the A/D converter circuit with wireless transceiver, nRF401 chip receives A collection and communication tools, the control of the signal transmission to the high W77E58 single-chip microcontroller, W77E58 rs-five fieldbus communication by means of transmission to 185, remote control center and data collection.
In the design process is considering ratio, low price and performance and stability of components. The data acquisition module has simple structure compact, real-time, high reliability and strong anti-jamming ability, etc. As a kind of remote data acquisition and monitoring device, general user just joined other required parameters can be realized, the corresponding sensor data collection and transmission function. To improve the production process automation and control the quality of management is very important significance.
