2. Industry status
With the development of China's economy, the expansion of city scale and the continuous improvement of modernization. The city's pipeline network system is also becoming larger and larger. Many pipelines have complicated landfills and unclear data. Some pipelines are even searched only by the memory of the construction staff at the time. Caused many design errors and construction accidents. Construct a pipeline network management system for information synthesis, analysis and decision-making based on the component GIS, and use the computer to visually manage the graphics and attribute data of the pipeline network. It is not only accurate and efficient, but also easy to update. Thereby greatly improving the efficiency and quality of pipe network management.
At present, there are a certain number of line patrol personnel in the gas and heat supply industries to conduct regular inspections on pipelines. Check whether the pipeline is damaged or leaking. In the past, it was difficult to know whether these line patrol personnel actually did it. With the pipeline patrol inspection, you can use the patrol inspection report module and GPS track module to check whether these line patrol personnel have conducted the line patrol. The line followers followed what path they took, and how long the line inspectors stayed at each location. They all made very detailed records. Line patrol personnel can also report to the information center through on-site inspection and reporting, on-site photos, languages, etc., the upper-end customer service and management staff can more clearly understand the scene.
With the development of enterprises and the replacement of old and new equipment, the increasing number of equipment brought certain pressure to management. In addition, since the devices are mostly located in public areas, with a wide geographical distribution and large span, it poses difficulties for management and increases potential security risks. Therefore, enterprises urgently need a set of practical and effective systems to comprehensively manage numerous equipments of enterprises and realize scientific management.
