Description

Technical Field

[0001] The present invention relates to the technical field of rail transit equipment, and in particular to a rail transit weather monitoring device. Background Art

[0002] Meteorological monitoring can provide real-time and accurate meteorological data, helping rail transit departments to keep abreast of weather changes. This is crucial for the safe operation of rail transit, as severe weather conditions such as heavy rain, strong winds, lightning, freezing, etc. may have a serious impact on train operations. Through meteorological monitoring, these potential risks can be discovered in a timely manner, and corresponding preventive measures can be taken to ensure the safety of train operations.

[0003] When the train conductor controls the train, he needs to watch the data displayed on the rail transit meteorological monitoring device. However, in bad weather, such as winter, due to the influence of humidity and temperature, ice will form on the surface of the monitoring device. These ice layers will cover or blur the displayed data, making it impossible for the train conductor to effectively receive information, which increases the safety risk when the train is moving. Improvements need to be made to this problem.

[0004] Therefore, it is necessary to design a rail transit meteorological monitoring device that is highly practical and can ensure accurate data display in severe weather conditions. Summary of the Invention

The heating frame is fixedly connected to the bottom of the connecting block, the heating rod is fixedly connected to the inside of the heating frame, the auxiliary support frame is fixedly connected to the back of the heating frame, and the cleaning roller is rotatably connected to the rear of the auxiliary support frame.

[0010] According to the above technical solution, the bottom of the adjusting gear is meshed with the top of the driven gear, and the rotating rod drives the driven gear to rotate through the adjusting gear, so that the adjusting gear drives the driven gear to rotate when it rotates.

[0011] According to the above technical solution, a rotating groove for accommodating the rotation of the adjusting gear is opened on the left side of the top of the protective top plate. The motor output shaft passes through the back of the protective top plate and extends into the protective top plate and is fixedly connected to the rotating rod. The front end of the rotating rod is rotatably connected to the front inner wall of the rotating groove, which can support the rotating rod.

[0012] According to the above technical solution, the rear side of the cleaning roller abuts against the front side of the data display screen, and when the cleaning roller contacts the front side of the data display screen, it can perform rolling contact work on the surface of the data display screen.

[0013] According to the above technical solution, an industrial computer is provided in the detection box, and the temperature monitoring module, humidity monitoring module, motor and heating rod are all connected to the industrial computer.

[0021] According to the above technical solution, the ice thickness prediction formula is:

[0022] ;

[0023] in:

[0024] : thickness of the ice layer (can be any unit, such as millimeters);

[0026] RH: actual humidity value (percentage);

[0027] a, b, c: constants, which need to be determined through experimental data;

[0028] This formula assumes that ice thickness increases when temperature and humidity are above their respective minimum values;

When the heating frame rotates, the cleaning roller on the auxiliary support frame on the back of the heating frame rolls and rubs against the surface of the data display screen, absorbing the ice layer and moisture generated on the surface of the data display screen to prevent the ice layer from continuing to accumulate. At the same time, by controlling the operation of the heating rod, the air outside the data display screen is first heated by the heating rod when it moves to the middle, thereby reducing the speed of ice formation.

[0034] When ice forms on the surface of the data display screen to a certain extent, the industrial computer controls the motor to rotate forward and reverse multiple times, so that the cleaning roller on the back of the heating frame can contact the ice layer on the surface of the data display screen multiple times, accelerating the melting of the ice layer. At the same time, since the heating rod continues to work, the temperature of the surface of the data display screen can be increased, further accelerating the melting of the ice layer. When the ice layer on the surface of the data display screen melts, the heating frames are controlled to be located on the left and right sides of the front of the data display screen to continuously increase the temperature of the front of the data display screen to avoid the formation of ice layer again.
