Design And Realization Of Remote Monitoring Terminal Unit For City Street Lamp

Based on the study of GPRS-Internet and the distributed computer measurement and control technology, this paper designs and implements a remote terminal unit of the city street lamps. The design integrates hardware and software application of a variety of anti-jamming technology. Remote terminal units have easy expansion, flexibility, cost-effective, and have a very good human-computer interaction and versatility. Pass the test, achieved the expected design requirements, in practical application achieved good results, with promotional value.The remote terminal unit of the city street lamps have multi-MCU and dual bus topology, the function and location can achieve a reasonable distribution .The protocol designed to meet the general requirements of industrial control, both Polling and the Statute of the characteristics of CDT, can be generally used by the others.
