Development of Pumping Wells Electrical Facility Remote Monitoring Terminal Based on DSP
Aimed at the features of large quantity and wide distribution of oil wells, this paper designs a pumping well remote monitoring terminal based on the two way automatic communication technology (TWACS). Processing signals from voltage sensor and current sensor, the terminal obtains electrical parameters so as to remotely monitor the well electrical facilities. Meanwhile, the modulation time domain of signals is determined by matched filter，and then the demodulation of TWACS signal and the transmission of monitoring data are achieved through the other technologies such as cross-correlation algorithm.
