Research of wireless distributed monitoring system for petrochemical equipment

To solve the problem of monitoring system for petrochemical equipment, proposing a three-level wireless distributed network monitoring application scheme. The terminal node and middle layer cluster head node of monitoring system were made up of short-distance wireless communication module nRF9E5 and GPRS network MC55 module. The wireless point to multi-point transceiver program based on dynamic multi-access frequency-hopping technology and the GPRS network transmission program based on the embedded TCP/IP protocol were designed. The results of the monitoring system experiments show that information transmission has lower energy consumption, quicker response, lower bit error rate, implementing wireless, efficient monitoring to petrochemical equipment.
