Description

Technical Field

[0001] The invention relates to the field of turnout snow melting control, and in particular to a turnout snow melting energy-saving control module system. Background Art

[0002] Turnouts are one of the key components in railway lines, used to guide trains to different tracks. When snow covers the turnouts, they may freeze, affecting their normal operation, and even causing safety accidents such as train derailment in serious cases. In order to ensure the safety and reliability of railway transportation, especially in winter and in areas with heavy snowfall, the use of advanced snow melting technology can effectively cope with the challenges brought by severe weather and ensure the smooth operation of railway transportation.

[0003] However, the existing turnout snow melting control system still has some limitations and shortcomings in practical applications.

[0004] For example, an existing Chinese patent with publication number CN116497639A discloses a turnout snow melting control system and method, and the main technical scheme of the application is: a monitoring terminal, which is used to monitor the equipment parameters and temperature parameters collected by the turnout snow melting intelligent control box, and send the monitoring instructions generated based on the operation events or the equipment parameters and temperature parameters to the turnout snow melting intelligent control box; the turnout snow melting intelligent control box is used to send the work instructions generated based on the received monitoring instructions or the collected equipment parameters corresponding to the heating equipment and the temperature parameters corresponding to the rail surface temperature sensor to the heating equipment; the rail surface temperature sensor is used to collect the temperature parameters corresponding to the two sides of the rails in any rail group in the turnout area, and send the temperature parameters to the turnout snow melting intelligent control box; the heating equipment is used to perform heating operations on the two sides of the rails in any rail group in the turnout area according to the work instructions, so that the snow covering the rail surface of the two sides of the rails melts. This application can control the heating equipment based on the equipment parameters of the heating equipment and the rail surface temperature fed back by the rail surface temperature sensor, or can autonomously control the heating equipment based on human operation events, avoiding the drawbacks of relying solely on the rail surface temperature for automatic control. It can receive parameter feedback from the heating equipment in a timely manner, avoid the occurrence of false start and stop, and can effectively avoid false control when the heating equipment fails, so that it can stably and accurately achieve the melting of snow on the rail surface, thereby improving the snow melting effect of the turnout.

[0005] However, the above patent has the following problems: (1) the heating device for melting snow on turnouts does not have multiple working modes to choose from, and thus cannot meet the diverse needs of users.

[0006] (2) The heating equipment is adjusted based only on the temperature meteorological data, without considering the possible impact of other meteorological data, such as rain, snow, wind, etc., which makes the adjustment of the heating equipment unreliable.

[0007] (3) After setting the operating parameters of the heating equipment, the actual heating effect of the heating equipment is not tracked and monitored to adaptively adjust the operating parameters of the heating equipment. As a result, the operating parameters may be set too high or too low, resulting in energy waste or heating effect not meeting expectations. Summary of the invention
