Analyze the performance of GPRS DTU and the impact on the remote monitoring street lighting system basebd on GPRS

This paper presents a method for implementing remote monitoring street lighting system based on virtual private networks. The communication between master station and substation is realized by using the data center which provides socket interface to communicate with GPRS DTU directly. With the use of the data center, it is of practical significance to implement multiple master stations to receive data from all slave stations simultaneously and to control all slave stations in parallel. The objectives of this paper are two fold. One is to present an overview of the architecture and protocol layers of remote wireless monitoring street lighting system. The other is to present the fundamentals of GPRS DTU and to analyze its performance and impact on the remote wireless monitoring street lighting system. At the same time, we also analyze the negotiation mechanism of point-to-point protocol in detail. A good foundation for further implementing a remote wireless monitoring system which uses point-to-point protocol to establish communication link between nodes is provided.
