[0062] Embodiment 3

[0063] See also Figure 3 , Figure 3 This is a flow chart of a control method for a turnout snow melting system according to a first embodiment of the present invention, which is applied to the turnout snow melting system according to the above embodiment, and the steps include:

[0064] Step S101, obtaining weather forecast information of the snowmelt area, weather station information of the station where the turnout rail is located, and real-time temperature of the turnout rail;

[0065] It should be noted that the snow melting area may refer to an area where turnout heating is required. The snow melting area may be a designated area or a certain cooling area obtained by intelligent monitoring, for example, a certain station area.

[0066] The weather station information refers to the weather data of the snowmelt area, and this information can be obtained through the weather station. In the embodiment of the present application, the weather station should be located near the snowmelt area to ensure that the obtained weather data accurately reflects the actual conditions of the area.

[0067] Weather forecast information is usually issued by national or local meteorological stations, focusing on weather conditions that affect the normal operation of turnouts, such as snowfall and freezing rain. It is particularly important to note that the weather forecast contains information such as temperature, temperature drop and snowfall, which have a direct impact on the normal operation of turnouts.

[0068] Step S102, intelligently controlling at least one turnout snow melting device in the snow melting area according to weather forecast information, the weather station information and the real-time temperature, so as to ensure that at least one turnout snow melting device in the snow melting area works normally.

[0069] In the embodiment of the present application, the cloud service end and the Internet of Things can receive and update the weather station information and weather forecast information of the snow melting area in real time. The monitoring center determines the weather conditions of the snow melting area based on this information. In addition, the monitoring center can also directly obtain the weather information of the area from the weather station.

[0070] In a specific implementation, intelligent control is performed on at least one turnout snow melting device in the snow melting area, including: broadcasting and issuing control instructions to at least one turnout snow melting device in the snow melting area through wireless communication.

[0071] A control method for a turnout snow melting system provided in an embodiment of the present invention includes: obtaining weather forecast information of a snow melting area, meteorological station information of a station where a turnout rail is located, and the real-time temperature of the turnout rail; intelligently controlling at least one turnout snow melting device in the snow melting area according to the weather forecast information, the meteorological station information, and the real-time temperature to ensure that at least one turnout snow melting device in the snow melting area works normally. Intelligently controlling the turnout snow melting device according to the weather forecast information and meteorological information ensures that the turnout snow melting device in the snow melting area can work normally. This improves the working efficiency of the turnout snow melting device and the turnout, and further improves the efficiency of railway transportation.

[0072] Embodiment 4

[0073] See also Figure 4 , Figure 4 This is a flow chart of a second embodiment of a control method for a turnout snow melting system of the present invention, which is applied to the turnout snow melting system of the above embodiment, and the steps include:

[0074] S201, obtaining weather forecast information of the snowmelt area, weather station information of the station where the turnout rail is located, and real-time temperature of the turnout rail;

[0075] S202, if the weather forecast information satisfies the preset turnout heating condition, or the weather station information satisfies the turnout heating condition, controlling at least one turnout snow melting device in the snow melting area to start, so as to heat the turnout rail;

[0076] The turnout heating condition may refer to a condition under which turnout heating can be performed after a preset weather condition is met, for example, the temperature in the snowmelt area reaches below a preset temperature, or snowfall occurs in the snowmelt area, etc. The preset weather condition and the preset temperature may be adaptively adjusted by those skilled in the art.

[0077] In the specific implementation, the monitoring center intelligently controls at least one turnout snow melting device in the snow melting area according to the turnout heating conditions and the weather information determined by the cloud server and the Internet of Things connected to it, to ensure that at least one turnout in the snow melting area can work normally.

[0078] S203, monitoring the real-time temperature of the turnout rail during the heating process of the turnout rail;

[0079] Specifically, after the turnout snow melting equipment is turned on, during the process of heating the turnout rails, the real-time temperature of the turnout rails during the heating process is obtained through the rail temperature monitoring sensor and the infrared temperature sensor.

[0080] In an optional embodiment, the real-time temperatures of the turnout rail obtained by the rail temperature monitoring sensor and the infrared temperature sensor respectively may be added and averaged to obtain the final real-time temperature of the turnout rail, so as to reduce the error of the obtained real-time temperature of the turnout rail.

[0081] S204, adjusting the heating power of the turnout snow melting equipment according to the real-time temperature until the heating operation is completed.

[0082] In the embodiment of the present application, the command to the turnout snow melting device can be issued by the monitoring center, or the user can issue the control command through the mobile terminal. The control command can be a control command broadcasted to at least one turnout snow melting device, or a separate session control command manually set and sent to a turnout snow melting device.

[0083] Furthermore, according to the obtained real-time temperature of the turnout rail during the heating process, the monitoring center can adjust the heating power of the turnout snow melting device according to the real-time temperature. For example, when the turnout snow melting device starts to work, the temperature of the turnout rail is low. At this time, the monitoring center can send a control command for the turnout snow melting device to work at high power to control the turnout snow melting device to work; after the turnout snow melting device has worked for a period of time, the temperature of the turnout rail will continue to rise. When the temperature of the turnout rail is close to the preset temperature, the monitoring center can send a control command for the turnout snow melting device to work at low power to control the turnout snow melting device to work; when the temperature of the turnout rail is greater than or equal to the preset temperature, the monitoring center can send a control command for the turnout snow melting device to work in a dormant state to control the turnout snow melting device to enter a dormant state.

[0084] After the turnout snow melting device enters the dormant state, when the temperature of the turnout rail is lower than the preset temperature, the monitoring center can send a control command for the turnout snow melting device to work at low power, and control the turnout snow melting device to work, so as to ensure that the turnout device can always work normally when the weather information in the snow melting area meets the turnout heating information. The heating information may include at least one of the following: heating power, current information, and temperature information.

[0085] In a specific implementation, the heating information also includes the working state corresponding to the heating power of the turnout snow melting equipment, including: a dormant state, a low power state, and a high power state.

[0086] At the same time, the turnout snow melting device can output its heating information to the monitoring center, and display the heating information at the monitoring center so that the user can intuitively observe the heating information of the turnout snow melting device.

[0087] A control method for a turnout snow melting system disclosed in an embodiment of the present invention includes: obtaining weather forecast information of a snow melting area, weather station information of a station where a turnout rail is located, and the real-time temperature of the turnout rail; intelligently controlling at least one turnout snow melting device in the snow melting area according to the weather forecast information, the weather station information, and the real-time temperature to ensure that at least one turnout snow melting device in the snow melting area works normally. Intelligently control the turnout snow melting device according to the weather forecast information and the weather information to ensure that the turnout snow melting device in the snow melting area can work normally. By improving the working efficiency of the turnout snow melting device, not only can the overall efficiency of railway transportation be improved, but also the turnout snow melting device can be started to heat the turnout rail according to the weather conditions in the snow melting area when the heating requirements are met. During the heating process, the system will monitor and feedback the temperature of the turnout rail in real time, and dynamically adjust the heating power according to the real-time temperature, thereby reducing power loss and increasing the effective power of the heating equipment.
