基于GPRS的混合动力试验台架远程数据采集系统研发

Research on Remote Data Acquisition System of Hybrid Test Bench Based on GPRS

为了实现数据的远程传输,文章给出了一种采用GPRS技术将单片机采集的数据传输到监控中心的方案。在该系统中,单片机的AD口把传感器采集的模拟量转化为数字量,再通过GPRS网络和Internet网络把数据传输到上位机。以采集混合动力试验台架转速转矩的试验结果表明,此系统实现了数据的实时采集、处理、远程传输和监控等功能。

In order to achieve remote data transmission,a program of transmitting remote data to monitoring center was designed based on GPRS technology.In the system,the analog from sensor was turned into the digital quantity by the AD port of MCU,and the digital data was transmitted to PC by GPRS network and Internet.The test results show the system realizes the functions of real-time data acquisition,data processing,remote transmission and monitoring.
