The Design Of GPRS-based Monitoring System Of Distribution Transformer

According to the request of monitoring system of distribution transformer to date reliability and real-time, and combining the GPRS wireless date network technology, a monitoring system of distribution transformer is designed. In this paper, design idea and functions of the full system are introduced, based on which, the system structure and the scheme realization are analyzed and studied deeply, and the communication method based on GPRS network is put forward.Aim at the current practical situation, a kind of design procedure is presented on terminal based on ARM, and the ARM microprocessor is selected combining with the demand of the subject. The hardware system and software based on the LPC2124 and the periphery interface chipset is designed. The reliability of the entire system is also analyzed. In the design of date transmission system, the design of layers is elaborated on such as data link layer, transport layer and application layer. It is also emphasized that design of control system and the realization of interrelated technology including PCU and CCU.The system also ensures the reliability, and real-time of the data transmission, so the designed monitoring system of distribution transformer based on GPRS has good spread value.
