Thermal inspection system thermal industry as overall national economic development has basic industries guiding influence, and people's lives. China's urban district heating from the 1950s started. In recent years, with the reform and opening up, the development of the national economy and people's living standards improve, people's living conditions continue to improve. Our central heating career development has been rapid, with the amount of users increases, the load caused by pressure on the heating pipe network also increased, companies in order to ensure the safety of heating heating pipe network to millions of households , it is necessary to strengthen the safety of more than routine maintenance of heating pipes, heat pipe network on the current status of routine maintenance inspection line patrol officers work or confined to paper-based records, data incomplete statistics, reported no hidden layers in time, it may be brewing small hidden by larger accident, there are a lot of buried pipeline inspection staff position uncertainty underground pipe network, greatly reducing the work efficiency, and inspection personnel are difficult to manage, work hard to assess. First, the current status of a traditional multi-use manual recording inspection, inspection is not in place, omissions inspection point, the data stored is incomplete, inaccurate, loss of data, omissions and other serious problems. 2, found hidden points (such as pipe insulation off valve leakage embroidered eclipse) can not timely reporting, and hidden locations, describing the situation is not clear, for the case can not cause heating network and facilities for routine maintenance and repair, from small risks up to a big accident, resulting in a large area of ??the pipe network and the residents suffer. 3, heat transfer stations within a water supply pipe network pressure, backwater pressure secondary pipe water temperature, return water temperature is running no way to verify the data. 4, when the incident occurred, not directly reported to be directly responsible for the department, the relevant department notified the first time unable to find the nearest repair personnel, organization of work can not be nearby, delay the repair time, increased accidents. Second, Chi Chong heating pipe network inspection program 1, GIS resource management system can be within the jurisdiction of the geographical coordinates of heating network and heat transfer stations directly into the post-acquisition system, the formation of the electronic analog map the entire heating system, the real intuitive to show on the map. For Qiangai, new pipelines and heat transfer stations, hidden, the maintenance point mark, achieve grid management model. ???? In the event of sudden failure, handheld terminals map navigation feature allows staff intuitive, ready to find fault site, shortening the heating rescue time and improve the emergency rescue capability. 2, to develop inspection standards were set, timing, quantitative, standard inspection given method, handheld terminals to facilitate inspection personnel to report incidents, submit heat transfer station equipment operating data (once the pipe network water pressure, backwater pressure, two second pipe water temperature, return water temperature) is simple and practical. 3, real-time supervision of all distributed in different regions of inspection, whether maintenance personnel and vehicles, working hours are seriously working in jobs. They can always spot inspection trajectory of history and dynamic playback. 4, the completion of the report of inspection, quantify, intelligent analysis and statistics at a glance. 5, hidden location, equipment operating status quo graphic display, accurate, intuitive and provide a strong reference for the development of maintenance and construction projects.
