Description

Switchgear snow melting device and “touch” type communication control device {Switch Point Heating System}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a splitter snow melting apparatus and a "touch" type communication control apparatus of a railway rail train, and to prevent the rail rail from malfunctioning due to snowfall or freezing. The present invention relates to a switchboard snow melting device and a "touch" type communication control device of a railroad railroad train that performs rapid heating and thawing in sequence according to atmospheric temperature conditions and controls the progress of the site through a communication method.

In general, railway rail trains are separated and combined at regular intervals by changing the tracks of the railway rails to change the direction of travel of the rails. This is because the train runs on the rails, so you can change the route only by changing the direction of the rails.

However, when the winter season changes the line changer to freeze due to snowfall or freezing, and malfunction of the train occurs, it is not only difficult to change the route of the railway, but also to derail the train. There was also a fear of a safety accident.

In order to solve this problem, snow melting methods such as hot water, warm air, warm oil circulation, and antifreeze circulation are used to prevent freezing due to snowfall or freezing. There is a risk of breakage due to freeze expansion, and it is not a good way in terms of economics such as heat loss because it is necessary to supply hot water in spite of high and low temperature in winter.

Next, the warm air type does not have the drawback of the hot water type, but since the heat content per unit volume is significantly smaller than that of the hot water, not only does it require a large amount of air volume for the same heating amount, but it is impossible to reach the warm air to a long distance, and uniform heating is performed. The effective distance is at most 10 meters.

In the warm oil or antifreeze circulation system, there is a disadvantage that oil or antifreeze flows out near the rail due to breakage of the circulation system, resulting in pollution.

Therefore, in recent years, the electric heating method has been used, the heater is installed on the rails of the railway rail train, so that the heater is operated when the standby temperature is lower than the set temperature, so that the operation of the train can be operated without difficulty even in winter, Most of them are based on a portable controller that can be attached to a dispatch point or control unit when setting the temperature.They keep running heaters until they are below the temperature. This is inconvenient because it depends on.

In addition, since the snowfall sensor is a system that attaches to the rail, if the freezing point is lower than the actual installation, the snowfall sensor itself freezes until snow melts until the ice accumulated in the sensor box melts. As the current continues to be consumed, there is no sense in automatic equipment.

That is, such a method is to operate the heater when the temperature is lower than the temperature by the set average value so that snow or wind blows, and when an error factor of thermal conductivity occurs, an error occurs in the heater operation, resulting in partial freezing. This causes a fault in the operation of the transfer machine.

In addition, since the thermal conductivity of the rail itself is different from the thermal conductivity of the rail itself in heating the heater, it is difficult to maintain the temperature, and each time the temperature is reset, there is no alternative in case of loss.

The present invention aims to solve this problem, and an object of the present invention is to preheat when the temperature of the air decreases, and to allow rapid heating when the snow falls in this state, while on the other hand, the manual or semi-automatic mode in preparation for the heavy snowfall for a long time. It is equipped with a cutting-edge communication system that connects the railroad rail turnover snow melting device and its melting contents to the indoor touch box of the "touch" method to prepare the molten water to penetrate the ground after snow melting and react sensitively to the change of the environment of the train. The system is to provide that device.

To this end, the present invention is to preheat when the air temperature is below the reference temperature, to perform rapid heating (manual mode) when the snow comes, to maintain the heating temperature when reset for the thawing, and to stop when the thawing is completed do.

When the thawing is completed, this is sequentially performed, including a preheating step (automatic) (S40) that maintains the rail at the primary set temperature until the atmospheric temperature is above the reference temperature.

The preheating step (S10) checks until the atmospheric temperature falls below the reference temperature (for example, 5 ℃) (S11), when the reference temperature is lower than the operating temperature for the preheating rail to preheat the rail to the first set temperature (Eg, 15 ° C.) is maintained (S12).

The rapid heating step (S20) checks through the sensor whether the snow is coming while the weather is cold during the preheating step (S10) (S21).

When the snowfall is confirmed, it is switched to the rapid heating (manual) state (S22), and the rail is rapidly heated to heat until the secondary set temperature is reached (S23).

The present invention is a system conceptual diagram, as shown in Figure 3, the preheating step (S10), rapid heating step (S20), thawing step (S30), preheating step (S40) of the touch-type communication system of the indoor control box (S50) This is done.

The communication system (S50) of the indoor control box is configured to check and control the function of the melting contents of each distribution box and the entire system of the area in a "touch" manner through the screen.

In the present invention, the reference temperature (5 ° C) is preferably set at a deviation of about 1 ° C, and the reference temperature is set at 5 ° C. The railroad is a mountainous area with high temperature fluctuations in the atmosphere or a track of humans. Because it is installed on the back, the temperature drops sharply in winter, and the haptic temperature is often lower than that (this means that the temperature difference from the ground surface cannot be ignored when the temperature is measured at 1 meter above the ground. The limit of freezing temperature due to instantaneous temperature drop was calculated at 5 ° C.

Therefore, the present invention is to preheat the railway fixed rail (1) and the moving rail (2) by taking a preheating method of low power consumption in order to prevent the case in which the train is frozen due to the instantaneous temperature drop.

Of course, the principle of heating itself is to use the conventional principle as it is, the description thereof will be omitted.

According to the present invention, the reference temperature is calculated at 5 ° C. (4-6 ° C. with an error) on the basis of the above, and whether the air temperature is lower than the reference temperature (5 ° C.) from the control unit 11 through the air temperature detection sensor 9 Judgment (S11), if it is determined to be low, the preheating step is performed to supply electricity to the heater 6 and to heat it, so that the temperature of the railway fixed rail 1 through the rail temperature monitoring sensor 7 is the primary set temperature ( It is to be heated until it is 15 ℃ (S12) to perform the preheating step (S10).

At this time, the primary set temperature is set to 15 ° C, as well as to take into account the deviation of 2 ° C (13-17 ° C), which is intended to be adjustable in consideration of the characteristics of the local air outside the train is installed. This is to calculate the temperature to maintain the temperature that can prevent partial freezing due to sudden snowfall and to obtain a rapid freezing effect (within 20 seconds) in consideration of thermal conductivity.

Of course, the size or length of the train machine may not be constant according to the region or location, so it is better to adjust the standard of the first set temperature.

In this case, since the rapid heating during preheating, the rapid heating completion time is short (within 20 seconds), which reduces the case of freezing.

As described above, the controller 11 recognizes this by the operation of the snowfall monitoring sensor 8 installed in the command room and the distribution box, while actively waiting for a change in the atmospheric temperature in the preheating step S10 (S21). 6) Increase the power supplied to the rapid heating (S22), and heats until it reaches the secondary set temperature (25 ℃) (S23) to perform a rapid heating step (S20).

The rapid heating temperature of 25 ° C is a temperature test that prevents freezing of the train parts due to cooling when the surrounding cold air is aberration due to snowfall. It was set at 25 ° C. which is the most appropriate condition, knowing that it provides the most efficient effect.

In this case, if snowfall continues (S32), it recognizes it through the snowfall snowfall monitoring sensor (optional) and continuously controls the secondary set temperature (25 ° C) to perform the thawing step (S30). Command to heat the heater 6 (S31).

When the snowfall stops, the control unit 11 recognizes the detection signal through the snowfall rainfall monitoring sensor 8, and returns to the preheating step when the atmospheric temperature is 5 ° C. or less by referring to the input signal of the atmospheric temperature detection sensor 9. To achieve the first set temperature (S40).

Then, the preheating step (S10) of determining whether the atmospheric temperature is still below the reference temperature (15 ° C.) is performed.

The present invention described above is not limited to the above-described embodiments and drawings, and various permutations, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

As described above, the present invention prevents a malfunction of the railway rail train that may occur due to snowfall or freezing, and in particular, when the temperature falls below a set temperature to enable rapid heating during snowfall, the preheating step is performed in advance so as to rapidly heat during snowfall. It allows the time to be within 20 seconds to prevent the instant freezing.

In addition, when snowfall persists after rapid heating, it is possible to prevent the freezing caused by snowfall by performing the thawing step to maintain the conditions under rapid heating, thereby preventing safety accidents.

In addition, the present invention contributes to energy saving due to less power consumption as compared to the method of rapid heating when necessary by always preheating with a small power when the temperature decreases so that rapid heating is possible.
