The present invention relates to a displacement detecting and sprinkling device and a method of a railway rail expansion joint, and more particularly, to the expansion and contraction of railway rails due to the influence of cyclic conditions such as the repeated operation of the train and the temperature and external weather of the rail itself. Detects the displacement of the seam in real time and if the displacement of the rail rail expansion joint is out of the allowable limit, it is possible to quickly return to within the allowable speed through emergency watering on the rail expansion seam to prevent the train operation accident. The present invention relates to a displacement sensing and sprinkling device of a joint and a method thereof.

In general, the rail of the railway is stretched or stretched in the longitudinal direction due to the climatic conditions such as temperature and weather and the repeated operation of the train. When the rails are stretched by thermal expansion, both ends of the rails facing each other are in close contact with each other, causing a phenomenon that the rails are pushed or bent in the width direction of the rails, which may cause a derailment accident of the running train.

In order to solve the problems caused by the expansion and contraction of these rails, expansion joints are provided at the ends at predetermined intervals between rails in the long rail section, and the displacement of the expansion joints is measured regularly or irregularly to secure the safe operation of the train.

It proposes a technology configuration that can alarm the city.

However, due to anomalous high temperature phenomenon caused by environmental destruction and greenhouse effect, anomalous high temperature phenomenon is occurring frequently, especially in summer, when the temperature rises rapidly. These abnormal high temperatures cause rapid temperature rises around the rails or the rails themselves, causing excessive thermal expansion of the rails and exceeding the displacement tolerances of the expansion joints, which poses a serious risk factor for safe operation of the train.

However, the above-described conventional technology measures and detects only the displacement in the longitudinal direction of the rail expansion joint, so when an error or a failure occurs in the displacement measurement portion of the rail expansion joint, there is no other incidental detection means, thereby detecting the risk of the rail expansion joint displacement. There is an impossible problem. In addition, the above-described prior art can only warn the administrator via e-mail or SMS when the displacement allowance of the rail expansion joint is exceeded due to a sudden abnormal high temperature phenomenon, and the rail construction is secured to secure the safe operation of the running train. There was a problem that the immediate and rapid action was impossible so that the displacement of the seam can be quickly returned within the allowable value.

Hereinafter, with reference to the accompanying drawings will be described with respect to the displacement detection and sprinkling device of the railway rail expansion joint according to an embodiment of the present invention and its method.

First, the displacement detection and sprinkling device of a railway rail expansion joint according to an embodiment of the present invention will be described in detail with reference to FIG. 1.

1 is a block diagram illustrating a displacement sensing and sprinkling device of a railway rail expansion joint according to an embodiment of the present invention.

Displacement detection and watering device of the railway rail expansion joint according to an embodiment of the present invention includes a sensor unit 100, the central server 200 and the watering unit 300.

The sensor unit 100 may include a stretch joint displacement measuring sensor 110, a stretch joint temperature measuring sensor 120, an external temperature measuring sensor 130, a timer 140, an auxiliary memory unit 150, a sensor controller 160, and the like. The sensor-side data transceiver 170 is included.

The expansion joint displacement measuring sensor 110 is a length displacement sensor that performs the same or the same function as that shown in FIGS. 3 to 5 installed on the expansion joint 10 of a railroad rail. It is a sensor which directly measures the displacement of the longitudinal direction of (10).

The expansion joint temperature measurement sensor 120 is a temperature sensor attached to the expansion joint 10 to measure the surface temperature. Since the displacement in the longitudinal direction of the expansion joint 120 is caused by thermal expansion or thermal contraction of the expansion joint 10, the expansion joint may be obtained by measuring the surface temperature of the expansion joint 10 even if the displacement of the expansion joint 10 is not directly measured. The displacement of (10) can be measured indirectly.

The external temperature sensor 130 is a temperature sensor installed around the expansion joint 10 to measure the ambient temperature. The displacement in the longitudinal direction of the expansion joint 120 is made by thermal expansion or thermal contraction of the expansion joint 10, the thermal expansion or thermal contraction of the expansion joint 10 is affected by the external ambient temperature, so the vicinity of the expansion joint 10 When installed at the periphery to measure the ambient temperature, the displacement of the expansion joint 10 can be indirectly measured.

In the present embodiment, in addition to the expansion joint displacement measurement sensor 110 capable of measuring the displacement of the expansion joint 10 directly, the expansion joint temperature measurement sensor 120 and the external temperature measurement sensor 130 are provided. In order to prepare for the failure of the expansion joint displacement measurement sensor 110 and to predict the displacement of the expansion joint 10 quickly in the event of a temperature change such as a rapid rise in temperature, it is possible to quickly take necessary measures in advance.

The timer 140 analyzes a control signal regarding a time interval between the expansion and contraction joint information data transmissions input from the main controller 230 and causes the sensor controller 160 to measure the various expansion joints measured by the sensors 110, 120, and 130. It is used to count the time for transmitting information data after the transmission time interval has elapsed.

The auxiliary memory unit 150 is provided for the sensor unit 100 to store and store various expansion joint information data measured by the sensors 110, 120, and 130.

The sensor controller 160 expands and contracts the displacement data and the temperature change data of the expansion joint 10, which are expansion joint information data measured by the sensors 110, 120, and 130 according to the set reference value transmitted from the main controller 230. The temperature change data around the joint 10 is collected and transmitted to the main controller 230.

At this time, the transmission condition for the sensor controller 160 to transmit the various expansion joint information data measured by each sensor 110, 120, 130 to the main controller 150 is measured by each sensor 110, 120, 130. Various expansion joint information data exceeds the reference value transmitted from the main controller 230, or the displacement or temperature is changed or the data transmission time interval is exceeded.

Here, the reference value refers to a value within a displacement allowance of the rail expansion joint 10 that can guarantee the safe driving of the train, and the actual displacement allowance of the rail expansion joint 10 or the expansion joint 10 itself temperature or expansion joint. It may be a value within an hourly allowable amount of change of the ambient temperature of (10) or an absolute temperature change allowable value.

That is, the sensor controller 160 may include at least one of the displacement of the expansion joint 10 portion, which is the expansion joint information data, the change in temperature of the expansion joint 10 portion, and the change in the ambient temperature of the expansion joint 10 portion. The displacement of the expansion joint 10 portion measured by the respective sensors 110, 110, and 120, the temperature variation of the expansion joint 10 portion, and the expansion joint portion when the reference value set and transmitted by 230 is exceeded. All of the change amount data of the ambient temperature of 10 are transmitted to the main controller 230.

In addition, the sensor controller 160 may be configured even if at least one of the displacement of the expansion joint portion, the temperature change amount of the expansion joint portion, and the change amount of the ambient temperature of the expansion joint portion does not exceed the reference value set by the main controller 230. When the time measured by the timer 140 exceeds the data transmission time interval set by the main controller 230, all of the measured data are transmitted to the main controller 230.

In addition, the sensor controller 160 may transmit all of the various expansion joint information data to the main controller 230 when a data transmission command signal for transmitting the immediate expansion joint information data is transmitted from the main controller 230.

If the sensor controller 160 exceeds the data transmission time interval even though the expansion joint information data measured by each sensor 110, 110, 120 does not exceed a corresponding reference value, the various control items of the expansion joint information are measured. The reason for transmitting to the 230 is to inform the main controller 230 that the sensor unit 100 is operating normally.

Here, the displacement of the expansion joint 10 portion refers to the amount of change in the length when any one of the four expansion joint displacement measurement sensor 110 is installed plus or minus the length change by the reference value set per hour.

On the other hand, the amount of change in the temperature of the expansion joint 10 portion is changed when the surface temperature of the expansion joint 10 portion detected by the expansion joint temperature measurement sensor 120 is changed to a positive or negative temperature by the reference value set per hour Refers to the temperature change amount.

In addition, the amount of change in the ambient temperature of the expansion joint 10 portion refers to the amount of change in temperature when the ambient temperature sensed by the external temperature measuring sensor 130 is changed to a positive or negative temperature by the reference value set per hour.

On the other hand, the sensor controller 160 is the displacement of the expansion joint 10 portion, which is the expansion joint information data measured by each sensor (110, 120, 130), the temperature change of the expansion joint 10 portion and the expansion joint 10 portion When the total amount of change in the ambient temperature does not exceed the reference value, and the time measured by the timer 140 does not exceed the data transmission time interval set by the main controller 230, the measured expansion joint information The data is stored and stored in the auxiliary memory unit 150 by itself so that unnecessary communication with the main controller 230 may not occur. In addition, when the control unit 160 does not receive a control signal regarding the reference value, data transmission time, etc. from the main control unit 230 for a predetermined time or more, the main control unit 160 determines that the current expansion joint information data cannot be received. Until the 230 transmits the next control signal, the measured elastic joint information data is stored in the auxiliary memory unit 150 without transmitting to the main control unit 230 so that unnecessary communication with the main control unit 230 does not occur. .

The sensor-side data transceiver 170 transmits various data or control signals to each other wirelessly by the server-side data transceiver 250 through a CDMA communication scheme.

The central server 200 includes an input unit 210, a main memory unit 220, a main control unit 230, a display unit 240, and a server-side data transmitting / receiving unit 250. The sensor unit 100 and the sprinkler unit ( 200) may be a personal computer that can be simply provided in the history or central control room of the railway, subway or light rail so as to send and receive data or control signals through CDMA communication, respectively.

The input unit 210 is set by the administrator as a setting criteria for the displacement of the expansion joint 10, the temperature of the expansion joint 10 and the external temperature change amount, which is a condition for transmitting various expansion joint information data measured by the sensor unit 100 When it is necessary to modify the value or the data transmission time interval and the displacement tolerance of the expansion joint 10, etc., a control signal for changing the reference value, the data transmission time interval or the displacement tolerance, etc. is input to the main controller 230.

The main memory unit 220 is built-up data such as the displacement allowance of the displacement of the rail rail expansion joint 10, which can ensure stable railway operation through experiments or field tests, etc. The joint information data and the input value of the input unit 210 are stored.

The main controller 230 designates a transmission condition of the various expansion joint information data measured by the sensor unit 100, and receives the data measured by the sensor unit 100 when the transmission condition corresponds to the displacement of the expansion joint 10. Determines whether the value exceeds the allowable value. If the allowable value is exceeded, the main control unit 230 causes the sprinkling unit 300 to automatically perform the sprinkling operation of supplying water to the expansion joint 10 immediately, so that the displacement of the expansion joint 10 portion is increased. The spraying unit 300 is controlled to return quickly within the allowable value and to automatically stop the spraying operation when the displacement of the expansion joint 10 is returned within the allowable value.

In addition, the main control unit 230 does not receive the data even if the condition for receiving the various expansion joint information data measured from the sensor unit 100 exceeds the data transmission time interval, or transmit the expansion joint information data immediately. When the data transmission command signal is transmitted to the sensor control unit 160, but the expansion and contraction information data is not received from the sensor unit 100, it is determined that the operation of the sensor unit 100 is abnormal and displayed on the display unit 240 to the administrator. Warning.

Meanwhile, the main controller 230 transmits a control signal regarding a reference value, a data transmission time interval, and the like to the sensor controller 160 at a predetermined time interval, thereby informing that the main controller 230 is operating normally. The sensor controller 160 may determine whether transmission of the expansion joint information data measured by the controller 120, 130, or the like is possible.

The display unit 240 may include a reference value set by the main controller 230, various expansion joint information data transmitted by the sensor unit 100, a data transmission time interval, an abnormal operation of the sensor unit 100, and a water sprinkler ( Information related to the operation of 300) is displayed.

In the present embodiment, the display unit 240 may be provided as a visual display device such as a display, but may be provided as an acoustic display device such as a warning notification sound or a device including both.

The server-side data transceiver 250 exchanges various data or control signals with the sensor-side data transceiver 170 and the sprinkler-side data transceiver 330 wirelessly by CDMA communication.

The sprinkling unit 300 includes a sprinkling control unit 310, a sprinkler 320, and a sprinkling side data transmitting / receiving unit 320, and is disposed near the expansion joint 10.

The sprinkling control unit 310 controls the operation of the sprinkler 320 according to the sprinkler operation control signal input from the main control unit 230 to automatically supply the water to the expansion joint 10 automatically, so that the expansion joint exceeds the displacement tolerance. 10 can be quickly returned to within the allowable displacement, and the water supply is automatically stopped when the expansion joint 10 returns to within the allowable displacement by the operation of the sprinkler 320. In addition, the sprinkling control unit 310 transmits the operation information and the operation stop information of the sprinkler 320 to the main control unit 230 so that the main control unit 230 can determine whether the sprinkler 320 is currently operating.

The watering-side data transmitting and receiving unit 330 wirelessly transmits the operation information data of the watering machine 320 by the CDMA communication method with the server-side data transmitting and receiving unit 250, and receives the operation control signal of the watering machine 320.

Hereinafter, the displacement detection and sprinkling method of the railway rail expansion joint according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

2 is a flow chart sequentially showing the displacement detection and watering method of the railway rail expansion joint.

1 and 2, the displacement detection and sprinkling method of the railway rail expansion joint according to an embodiment of the present invention, first, the displacement information data in the longitudinal direction of the railway rail expansion joint 10, the expansion joint portion The elastic joint information data consisting of the temperature information data of the expansion joint and the surrounding temperature information data of the expansion joint portion starts from the elastic joint information data collection step (S10) collected by the sensor unit 100.

That is, the displacement information data in the longitudinal direction of the expansion joint 10 portion in real time using the expansion joint displacement measurement sensor 110, expansion joint temperature measurement sensor 120, external temperature measurement sensor 130, the expansion joint Temperature information data and expansion joint information data which is ambient temperature information data of the expansion joint part are collected.

The collected stretched joint information data is subjected to a step (S20) of determining whether the sensor unit 100 meets the condition for transmitting the stretched joint information data to determine whether the sensor 100 corresponds to a condition to be transmitted to the central server 200.

That is, the sensor controller 160 determines whether it corresponds to a condition for transmitting the stretched joint information data collected by the sensors 110, 120, and 130 to the main controller 230 of the central server 200, which is a personal computer.

In this case, when the transmission condition of the expansion joint information data is satisfied, the displacement of the expansion joint 10 portion, which is the expansion joint information measured by each sensor 110, 120, 130, the temperature change amount of the expansion joint 10 portion, and At least one of the amount of change in the ambient temperature of the expansion joint 10 portion is set by the main controller 230 and exceeds the above-described reference value transmitted to the sensor unit 100.

If the reference value is not exceeded, if the condition for transmitting the stretched joint information data is satisfied, the time is exceeded after exceeding the data transmission time interval set by the main controller 230 and transmitted to the sensor controller 160. If it is.

Meanwhile, when the expansion joint information data transmission condition is not satisfied, the expansion joint information data is not transmitted to the main controller 230, and when the expansion joint information data transmission condition is satisfied later, the auxiliary joint unit 150 transmits the expansion joint information data to the auxiliary memory unit 150 for transmission. Store and store as, the sensor unit 100 is to perform the step (S10) of collecting the expansion joint information data.

If the stretched joint information data transmission condition is satisfied, the sensor controller 160 performs a stretched joint information data transmission step S30 of transmitting the stretched joint information data collected by the main controller 230.

In this case, the transmission is performed using the CDMA wireless communication method.

Subsequently, the control unit 230 determines whether the expansion joint information data is normally transmitted whether the expansion joint information data is normally transmitted from the sensor unit 100 to the central server 200 (S40).

As a result of determining whether the expansion joint information data is normally transmitted, if the expansion joint information data is not normally transmitted to the central server 200, an operation (S45) of warning of abnormal operation of the sensor unit 100 is performed.

That is, when the main controller 230 does not normally receive the expansion joint information data from the sensor controller 160 even though the expansion joint information data transmission condition is met, it is determined that the main controller 230 is abnormal in the operation of the sensor unit 100 and is displayed through the display unit 240. By alerting managers, immediate actions can be taken.

On the other hand, when the expansion joint information data is transmitted normally, it is analyzed to determine whether the displacement of the expansion joint 10 part exceeds the permissible threshold and whether it corresponds to the watering condition that requires immediate watering operation. In step S50, the controller determines whether the expansion joint spout condition is satisfied.

As a result of the determination, when the expansion joint sprinkling condition is satisfied, the sprinkler 320 is operated to perform the sprinkler operation step S60 of supplying water to the expansion joint part.

That is, the main controller 230 transmits an immediate sprinkler 320 operation command signal to the sprinkling controller 310 of the sprinkler 300 through the CDMA wireless communication method, and the sprinkler controller 310 controls the sprinkler 320. To ensure that water is immediately supplied to the expansion joints which are thermally expanded beyond the permissible limits.

On the other hand, when the sprinkler 320 is operated, the sprinkler control unit 310 performs the sprinkler operation information data transmission step (S70) of transmitting the operation information data of the sprinkler 320 to the main control unit 230 through the CDMA wireless communication method. Thus, the main controller 230 can determine the current operating state of the water dispenser 320.

Then, the expansion joint stabilization step (S80) is performed to determine whether the displacement of the expansion joint 10 portion by the operation of the sprinkler 310 is stabilized by returning to the allowable reference value.

That is, the main controller 230 analyzes the expansion joint information data input from the sensor controller 160 to determine whether the displacement of the expansion joint 10 is within the allowable reference value and stabilized.
