By the end of 2007, there were 4,673 tunnels nationwide, an increase of 38.75% year-on-year. The total length of the tunnel was 2555.5 kilometers, an increase of 23.36% year-on-year, and the total length of the road was 3.5837 million kilometers, an increase of 3.67% year-on-year. The growth rate of the tunnel was much greater than the growth rate of the highway. Tunnel engineering has become an important part of highway development. Tunnel projects can effectively protect the environment, reduce land acquisition, and extend the highway to Dashan. However, because of the geographical distribution of the tunnel, the cost of building a cable network on the tunnel is high and maintenance is needed. The cost is high and it is abandoned. As a result, the highway management department wants real-time monitoring of the real-time data of various indicators inside the tunnel, and the reasonable control of lighting facilities, which cannot be realized due to the lack of a communication network. In recent years, with the GPRS network The rapid development, and the use of GPRS network for remote data acquisition and monitoring of the application of engineering has gradually matured, making GPRS network can effectively solve the tunnel-related equipment access network requirements.
Through the wireless GPRS network, the monitoring center can monitor the index data in the tunnel in real time. Once an abnormality occurs in the data, the monitoring center will send out alarm information in acousto-optic mode, prompting the monitoring personnel to arrange the processing quickly, making the inspection and repair of the tunnel facilities a “spectrumâ€. "Inspection" is changed to "duty shift", which can greatly reduce the labor intensity of maintenance personnel and improve the efficiency of inspections. At the same time, by using the GPRS wireless communication network, the monitoring staff can complete the lighting operation of the lighting facility just before the computer, as well as reasonable To adjust the on/off time of lighting facilities, it is not necessary to arrange personnel to make special trips to the site in order to adjust the time. This not only effectively saves electricity, but also improves work efficiency. At the same time, it strengthens the information, networking, and automation of highway management departments.

Monitoring terminal composition
The monitoring terminal hardware system consists of RTU intelligent controller, LCD local display controller, and GPRS DTU remote data transmission module. It is mainly used to realize the measurement and control of the site power and the collection work. The DTU transmits the site power information and alarm information to the landscape light monitoring and management center.
