In the process of realizing the remote control of electromotor meter, it probes into the realization of the GPRS wireless collector emphatically which is on the kernel ground. It adopts the means of area-centralizing control to manage the electromotor meters affiliated by it. It communicates with the central control station by GPRS Modem and transmits the commands and data to the instrument by wireless, which makes the collection and transmission of the field data come true. In the process of realizing the remote control of voltage transformer meter, according to the actual requirement, it adopted the chips and modules that are different from the front means to design and realize the GPRS wireless communicating controller corresponding with the devices. It also introduces the mixed—mode Communication integrating the GSM with GPRS to settle the problem that too many GPRS terminals connecting with the central control station synchronously will affect the performance of the central control station.As a whole system, the central control station is the kernel of the digital oil field.
