Thermal inspection system

Thread Content

As a fundamental industry that has a comprehensive and pioneering impact on the development of the national economy, the thermal industry is closely related to people’s lives, and thermal inspection systems are used in this sector. Central heating in cities in our country began to develop in the 1950s. In recent years, with the deepening of reform and opening up, the development of the national economy and the improvement of people’s living standards, people’s living conditions have been continuously improving. The centralized heating industry in our country has developed rapidly. As the amount of heat used by consumers increases, the pressure on the heating pipelines also rises. To ensure a stable supply of heat to thousands of households, it is necessary to strengthen the regular maintenance of these heating pipelines. At present, the personnel responsible for maintaining these pipelines still rely on paper-based methods for recording their inspections; as a result, data collection is incomplete, and potential problems are not reported in a timely manner. This can lead to small issues escalating into major accidents. Moreover, many pipeline inspectors are unable to determine the exact locations of the pipelines buried underground, which reduces work efficiency. It is also difficult to manage these inspectors and to assess their performance. I. Current Situation 1. Traditional inspection methods rely heavily on manual recording, leading to issues such as inadequate inspections, missed inspection points, incomplete and inaccurate data storage, as well as data loss and omissions. 2. Potential hazards such as the peeling of insulation layers on pipelines or corrosion and leakage in valves are not reported in a timely manner, and the location and nature of these hazards are not clearly described. As a result, it becomes impossible to carry out regular maintenance of the heating pipelines and related facilities, which allows small hazards to develop into major accidents, causing extensive damage to the pipelines and residents. 3. There is no way to verify the operating data regarding the supply pressure and return pressure of the primary piping network, as well as the supply temperature and return temperature of the secondary piping network within the heat exchange station. 4. In the event of an emergency, it is not possible to report it directly to the department responsible. Once the relevant departments receive the notification, they are unable to locate the nearest repair personnel immediately, nor can they assign tasks to them promptly, which delays the repair process and exacerbates the situation resulting from the accident. II. Intelligent Inspection Plan for Heating Pipeline Networks 1. The GIS resource management system can collect the geographic coordinates of the heating pipeline networks and heat exchange stations within its jurisdiction and import them directly into the system, thereby creating an electronic simulation of the entire heating system, which is displayed on the map in a realistic and intuitive manner. For the relocated and newly added pipelines as well as heat exchange stations, potential hazard points and maintenance points are marked to implement a grid-based management approach. In the event of a sudden failure, the map navigation function on handheld devices enables workers to locate the site of the failure quickly and easily, thereby reducing the time required to address the issue and enhancing emergency response capabilities. 2. Establish inspection standards, and define who will carry out the inspections, when, how often, to what extent, and using what methods. The handheld terminal facilitates inspectors in reporting incidents and submitting data on the operation of heat exchange station equipment (such as the supply pressure and return pressure in the primary piping network, as well as the supply temperature and return temperature in the secondary piping network), making it simple and practical to use. 3. Monitor in real time all inspection and maintenance personnel as well as vehicles located in different areas to ensure that they are working diligently at their posts during working hours. Historical inspection trajectories can be randomly checked at any time, and dynamic playback is available. 4. Inspection completion is reported, quantified, analyzed intelligently, and statistically summarized for clear visibility. 5. Graphic and textual displays of the locations of potential hazards and the current operating status of equipment, which are accurate and intuitive, providing a solid basis for formulating maintenance and construction plans.
