Description

Analyze the operation status and display of the track transition}

The present invention relates to a display device for analyzing the operation state of the line changer, and more particularly, the control information input for the changeover operation of the line changer controlling the direction of the rail, the state information generated during the changeover operation, and each signal. The voltage detection data is recorded and displayed on the field analysis display and downloaded to a computer or transmitted from a remote site, and checked by the maintainer for inspection or manual operation.In case of an abnormal operation condition, the SMS is sent to the SMS through the CDMA modem. Immediately notify the alarm status. The present invention relates to a display device for analyzing the operation condition of the track changer to check the operation state of the track changer during the incoming and outgoing operation of the train, to improve the stability, to notify immediately when a failure occurs, and to improve the efficiency of maintenance by analyzing the stored data.

Track changer is a device installed on a track (rail or rail) installed to move a train or vehicle from one track to another.

The impact of a heavy vehicle moving, causing some looseness or wrong handling, creates the risk of train derailment or overturning. Thus, railroads require that handlers take considerable care and check their functioning from time to time.

The type of track changer currently used in Korean railways is classified into manual and power type in structure.

Here, the manual type has a handle connected to a moving high-tech track and turns it by hand, a marker track switch in the shape of an arrow's tail wing, and a chute track switch in the form of turning over half of the weight. There is.

In addition, the power type is an electric type by the action of the pneumatic action and the electric motor, and is installed in the station of most station yards and automatic closing section where wiring is complicated. It is efficient and safe because it is operated in batch at the place. Currently, most Korean railways use electric line converters, and only a few of them are used in vehicle bases, sidelines, and yards.

However, since the conventional line changer does not include a device which records the state of change of the line (orthogonality / reversal) or a failure state by itself or displays it to the driver of the vehicle (or train), the route deviation according to the state of the wrong line However, there is a problem that a derailment accident of a vehicle may occur due to a failure, and after an accident occurs, a case may not be found due to an analysis of the control information of the indoor control equipment, and thus the exact cause of the accident may not be found.

An object of the present invention for solving the above-mentioned problems is that the line changer receives the switch signal from the control device and automatically releases, switches or locks the motor by the motor driving unit, but at the time of site maintenance and inspection or operation of a specific situation. In the case of manual changeover, various check and changeover tests are performed, and this operation state is recorded in the internal memory to provide an operation state analysis display device which can be used as notification and analysis data immediately when a problem occurs.

The above description is made in the order of operation.

(A) the step of unlocking operation occurs as shown in Figure 1 when the motor drive of the line converter is started,

(b) the rail transition begins when the unlock is completed;

(c) initiating a locking operation when the rail transition is completed;

(d) The motor stops when the determination operation is completed.

In the step (a), the motor driving starts with the polarity of the AS power reversed. When the motor driving starts, the control information detecting unit 700, the state detecting unit 800, and the sensor detecting unit 900 inside the analysis display device 10 are started.

If the conditions do not match, the LED lamp 110 blinks, and if the detection conditions match, the position (N) or face (R) is displayed. In addition, if the detection voltage for each power supply is not the normal voltage for the operation state, the LED display 120 for the question mark blinks to indicate an abnormality. In addition, information on the occurrence of abnormalities in the operating status to be notified immediately via SMS. At this time, the processing unit 500 uses the information detected by each control information detecting unit 700 as latch information in the internal processing logic program, and inputs the state information input through the state detecting unit 800 and the sensor detecting unit 900. The detected voltage detection information is determined by a failure analysis algorithm to block the contents displayed on the display unit 400 or display other contents such as a failure indication. The processor 500 stores the information input through the control information detector 700, the state detector 800, and the sensor detector 900 and the information determined by the failure analysis algorithm in the storage memory 600 in order of occurrence time. When there is a data download request or a remote transmission request, the stored information is sequentially transmitted through the communication unit 1000 in sequence.
