Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a failure monitoring system capable of efficiently monitoring failures of devices such as a train control device such as a ground rail and a railroad crossing control device laid along a rail on which a train travels. .
[0002]
[Prior art]
Conventionally, for example, on May 15, 1997 (Japan) Electric Railway Technical Association of Japan, "Publication of Electricity Introduction Signal Series ATS / ATC for Railway Engineers" In the equipment section of the ATS-P device shown in 35 to 74, a code processor (EC) is installed for each traffic light, and each of the code processors has several ground terminals on a rail on which a train runs. Are provided at predetermined intervals. Each code processor is connected by a cable such as an optical cable, and the cable is connected to a station processing device.
[0003]
In the ATS-P device having the above configuration, predetermined ground information such as position information corresponding to the current signal of the traffic signal and distance information from the stop point to the stop point is transmitted toward the vehicle (train). In the ATS-P on-board device mounted on the vehicle, a predetermined stop pattern (sometimes called a speed check pattern) is created based on predetermined ground information obtained from the ground, and the speed is set. The train operation control according to the stop pattern is performed with reference to the traveling distance and the train speed obtained from the generator.
[0004]
Further, each of the above code processors has a failure detection circuit incorporated therein. If a failure occurs in a ground terminal connected to one of the code processors, information on the occurrence of the failure is transmitted via an optical cable. And transmitted to the station processor. Since the station processing device is connected to a host device such as a steady state monitoring system that constantly monitors the steady state of the entire ATS-P device, the station processing device can be quickly restored by an instruction from the host device.
[0005]
[Problems to be solved by the invention]
However, in the above-described conventional fault monitoring system, faults of devices connected to the station processing device via an optical cable or the like are constantly monitored in a centralized manner. There is a drawback in that recovery from a failure of equipment not connected to the device is delayed.
[0006]
For example, in the above-mentioned ATS-P device, a non-power-supply ground terminal called an ATS-P (n) ground terminal that is not connected to the code processor does not perform failure detection depending on the station processing device and its host device, Until there is a report that the predetermined information was not obtained from the ground side by the train crew, or due to the diagnosis result that the predetermined information can not be obtained from the ground side side in the periodic inspection car inspection There is a drawback that a failure cannot be detected until a failure is found, thus delaying recovery.
[0007]
In addition, various devices such as level crossings, alarms, and vehicle (vehicle) detectors are installed near the rails on which trains run, but since many of these devices are not centrally monitored, There was a disadvantage that recovery in the event of a failure was delayed.
[0008]
In order to solve such a drawback, when connecting a control device of equipment, for example, a railroad crossing control box and a station processing device with a cable such as an optical cable to transmit fault information to a higher-level device, the cable laying cost is increased. It was enormous, and it could not be introduced, especially in rural areas, because of the cost. In addition, even when connecting to an optical cable that has already been laid, a new problem that requires a change in the laying of the optical cable occurs.
[0009]
The present invention has been made in order to solve the above-mentioned drawbacks, and an object of the present invention is to provide a low-cost monitoring system capable of monitoring failures of various devices provided near a rail on which a train runs. It is to provide a monitoring system.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the failure monitoring system according to the present invention provides a failure monitoring system according to the first aspect, wherein the failure detection system detects failure of equipment provided near a rail on which a train travels; When a failure of a kind is detected, ground-side transmitting means for identifying the equipment related to the failure and transmitting predetermined failure information toward the vehicle, and a predetermined signal transmitted from the ground-side transmitting means. Receiving and storing the failure information, an on-board device mounted on the train, and, when the train is located at a predetermined location, the predetermined failure information stored on the on-board device of the train at the predetermined location. And a vehicle-side transmitting means for transmitting to the failure monitoring means provided on the ground at the location of the vehicle.
A fault monitoring system according to a second aspect of the present invention is characterized in that the ground-side transmission means and the vehicle-side transmission means use a continuously controlled ATS-P device. A failure monitoring system according to a third aspect of the present invention is characterized in that the equipment is a ground terminal not connected to the code processor.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a line section when the failure monitoring system according to one embodiment is applied to a continuously controlled ATS-P device.
[0012]
In the vicinity of the rail r on which the train A travels, ground children a1 and a2 corresponding to the devices of the present invention and level crossing devices (level crossing breakers, alarms, vehicle (automobile) detectors, etc., of the level crossing are included. , An alarm device A.). The rail r is provided with many ground wires, alarms, and the like in addition to the ground wires a1 and a2, but these are omitted to simplify the description.
[0013]
In the figure, S1 and S2 are traffic lights provided near the boundary of the track circuit, and among these traffic lights S1 and S2, the traffic light S2 is shown as a departure traffic light for the train stopped at the Ko station. The signal equipment box 1 is connected to each of the traffic signals S1 and S2, and can control the traffic signals S1 and S2 based on predetermined information such as external train detection information and departure permission information. The distance information corresponding to the signal of the traffic lights S1 and S2 can be output to each of the ground children a1 and a2. Therefore, when passing through each ground child a1, a2, the train A obtains the position information and the distance information from the ground child a1, a2 to the stop point, creates a predetermined stop pattern, and generates the stop pattern. Can be used to control train operation.
[0014]
In the figure, reference numeral 2 denotes a wireless device connected to each of the signal equipment boxes 1 so that the present information of the traffic signals S1 and S2 can be transmitted to the vehicle (train) via the antenna 2a. It is configured. Therefore, the train A continuously receives the present up information of the traffic light S1 or the traffic light S2 inside the ground child a1 or the ground child a2 (the left side of the ground child a1 or a2 in FIG. 1). The stop pattern can be updated. In addition, among these wireless devices 2, the wireless device 2 provided at the instep station is configured to be able to receive on-vehicle information, which will be described later, transmitted from the vehicle (train).
[0015]
In the figure, reference numeral 3 denotes a station processing device provided at the instep station, which can transmit information from the on-board (train) obtained via the wireless device 2 to a higher-level device such as a steady state monitoring system (not shown). Is configured. The station processing device 3 and the host device correspond to a failure monitoring unit of the present invention.
[0016]
In the figure, reference numeral 4 denotes a railroad crossing equipment control box, which is configured to be able to drive and control the alarm A by inputting a train entry / exit signal from a train position detection device (not shown). The level crossing control box 4 includes a circuit for detecting a failure of the alarm A. When the failure is detected, predetermined failure information to which the identification information of the alarm A is added is transmitted via the antenna 5a. It is configured to be able to transmit from the wireless device 5 to the vehicle (train).
[0017]
On the train A, an on-board device 10 and a wireless device 11 are mounted. The on-board device 10 is configured around a CPU, creates a predetermined stop pattern, and is configured to control the operation of the train A to a predetermined stop position according to the created stop pattern. The on-board unit 10 is connected to an on-board unit 12 provided at the lower part of the head of the train A. The on-board unit 10 includes ground information obtained from the on-board units a1 and a2 via the on-board unit 12. It is configured such that child information and speed (traveling distance) information from a speed generator 13 provided on the axle of the train A can be input. The wireless device 11 is configured to wirelessly communicate (communicate) with the wireless device 2 via the antenna 11a.
[0018]
Hereinafter, the control operation will be described. Now, it is assumed that the train A is running inside the traffic light S1, and that the traffic light S1 indicates a warning notice (Y notice). Therefore, the train A stops in the on-board device 10 at a predetermined position outside the traffic light S1 (on the right side of the traffic light S1 in FIG. 1) based on the Y indication obtained from the radio 2 of the traffic light S1. A pattern is created, and train operation control is performed using the created stop pattern.
[0019]
When the traffic signal S1 indicates the Y indication, for example, a predetermined ground terminal information cannot be transmitted from the ground terminal a1 toward the vehicle due to a disconnection or a contact between the cable between the ground terminal a1 and the signal equipment box 1. Is detected by a failure detection circuit (not shown), the failure information of the ground child a1 is transmitted to the wireless device 2. Therefore, from the wireless device 2, on-vehicle (predetermined failure information to which the notification information indicating that the traffic light S1 is the Y notification and the identification information of the ground child a1 indicating that the ground child a1 has failed are added. It is transmitted to train a). Therefore, when the train A enters the communication (communication) range of the wireless device 2 of the traffic light S1, the Y present information and the failure information are received.
[0020]
The on-board device 10 that has received the Y indication information and the predetermined failure information creates a stop pattern based on the received Y indication information and information obtained from the speed generator 13, and uses the created stop pattern. The vehicle enters the outside of the traffic light S1, and stores the received predetermined failure information (failure information of the ground child a1) in a memory (not shown) of the on-board device 10.
[0021]
The above-described failure information is stored in the memory of the on-board device 10 via the wireless device 5 connected to the railroad crossing device control box 4 even when the alarm A has failed. The failure information stored in this memory is transmitted to the ground side via the wireless device 11 and, as described later, the on-board device until a signal indicating that it has been received by the station processing device 3 is received from the ground side. It is held at 10.
[0022]
When the train A approaches the instep station, it stops before the signal S2 indicating the stop sign (R sign) (see the train A in the chain line in FIG. 1). Therefore, the train A receives the R announcement information from the wireless device 2. Also, the radio 2 installed at the instep station has a function of receiving information (signal) transmitted from the vehicle (train A). The stored failure information is received by the wireless device 2, and the received failure information is output to the station processing device 3.
[0023]
When the station processing device 3 receives the failure information indicating that the ground child a1 has failed from the train A, the station processing device 3 transmits the failure information to a higher-level device (not shown), and transmits the radio 2 And transmits predetermined information to the effect that the failure information has been received. Therefore, since the train A can confirm that the failure information has been transmitted to the ground, the failure information in the memory can be deleted.
[0024]
When the upper-level device (not shown) obtains from the station processor 3 that the ground child a1 is out of order, the upper-level device transmits the fault information to a predetermined place such as a maintenance staffing place such as a signal handling place. Therefore, the broken ground child a1 is promptly repaired.
[0025]
Note that, in the above example, the example in which the train A stops at the A station is shown, but the train A may pass through the A station. In this case, if the failure information is stored in the memory of the train A, the failure information is taken into the station processing device 3 when the train A is located in the communication range of the wireless device 2 of the signal S2. . Also, an example in which the failure monitoring system is applied to a line section of a continuous control type ATS-P device has been described. It can also be applied to -P devices and other controlled train operation devices. In this case, the equipment on the ground side is provided with a failure detection means and a transmission means for transmitting the failure toward the vehicle, and receives and stores the failure information transmitted from the ground on the vehicle. At the same time, there is provided a transmission means for transmitting the stored failure information to the ground failure monitoring means.
[0026]
