Description

  The present invention relates to a ground check system, and more particularly to a recording function of a security device that controls the speed of a train such as a curve, a branch, and a maximum speed limit in a railway.

As a prior art of a vehicle signal security device, there is an automatic train stop device (ATS-P device) using transponder technology. This ATS-P on-board device receives the digital transmission signal (information type, distance to stop signal, speed limit, immediate stop information, etc.) from the transponder ground unit (ATS-P ground unit) and checks the speed. A pattern is generated, and stop control and speed limit control are performed.
On the other hand, as a recording function of the ATS-P on-board device, a driving operation (powering, manual brake handling) that is input to the ATS-P on-board device at a certain time before and after the trigger point with the brake output from the ATS-P as a trigger point. , Switch operation, etc.), operation information recognized by ATS-P (recognition speed, travel distance, pattern speed, control information, etc.), ATS-P ground element information, and the like.
JP 2000-142406 A

  The ATS-P onboard device performs stop control and speed limit control based on the contents of the message from the ATS-P ground unit, but the ground unit data can be received as an ATS-P message (transmission method, code format, message) If the number of receptions, frequency band, modulation method, transmission speed, message length, and error detection method are normal and the driving direction on the vehicle matches the driving direction of the message, the message is controlled as a regular message. In addition, since it does not have an ATS-P ground unit database for the travel section, it does not have a function of determining an ATS-P ground unit message that the ATS-P onboard device must receive next. For example, where the ATS-P on-board device should originally receive the stop signal updating ground element, even if the updating ground element cannot be received due to some abnormality in the ground element, the ATS-P on-board apparatus will It does not detect that the child is abnormal. Also, for example, in the case of a single-track section or the like, a downhill ground element that should not be received in an uphill operation is received on the ATS-P vehicle even when the driving direction is consistent and received for control due to some abnormality in the ground equipment. The device does not detect that the ground unit is abnormal, and performs control according to the contents of the received message.

If any abnormality occurs in these ATS-P ground facilities, they can usually be extracted by detecting the abnormality on the ground facility side. However, an artificial ATS-P ground unit installation position that is difficult to prevent by anomaly detection at ground facilities, setting data input errors, etc. are normal on the ATS-P on-board device side. Even if the train cannot be received, there is a problem that the abnormality does not appear as long as the train speed does not exceed the pattern or the vehicle operation is not hindered.
The problem that the abnormality of the ATS-P ground element is not surfaced is not a problem related only to the ATS-P apparatus, but is a problem common to the security apparatus using the transponder technology.

  Therefore, the present invention compares the recorded ground data collected by the recording function of the security device with the ledger ground data using the ground data check system, and detects abnormalities in the ground elements, poor installation, and abnormal settings data. The purpose is to provide a ground check system.

  Therefore, the present invention provides a record storage area of “terrestrial telegram” in advance in the function of the security device, and runs the route on which the ground element is to be measured by a vehicle equipped with a security device having the ground slave message recording area. The reception date and time, the ground slave message, the driving direction switch setting information, the travel distance, etc. are recorded with the time when the slave message is received as a trigger point. After collection, the data in the ground child message storage area is read out. Control of security devices such as ground interval of the recorded ground element data and ledger ground element data, information type, distance to stop signal signal, signal display code, distance to stop signal, speed limit, etc. for the read ground element By comparing the necessary data and outputting differences, it is possible to detect ground unit abnormalities, installation defects, and setting data abnormalities.

  That is, the present invention is mounted on a traveling train, and is based on the contents of messages collected from the ground unit during train traveling, the train stop control, the speed limit control security device, and the security device recording function. A ground unit data check system is provided for comparing the recorded ground unit data of the collected ground unit and the pre-created register unit of the ground unit, and the installation interval, information type, signal type, and signal status of the ground unit are provided. This is a ground check system that outputs the difference in data necessary for control of the safety device such as the display code, the distance to the stop signal, and the speed limit.

  Further, the present invention is a ground unit check system in which the security device has a region for recording ground unit data collected by traveling a mounted train exclusively for ground unit inspection.

  The present invention is a ground unit check system in which the security device sets a ground unit detection section according to a ground unit interval on a ledger and collects recorded ground unit data of the ground unit.

  Further, the present invention is a ground unit check system in which the security device records when a ground unit telegram is received, when recording ground unit data of the ground unit is collected by a recording function.

  According to the present invention, there is provided a ground unit check system that compares recorded ground unit data collected by a recording function of a security device and ledger ground unit data, and detects ground unit abnormality, installation failure, and setting data abnormality. Can do.

The best mode for carrying out the present invention will be described.
Embodiments of a ground check system according to the present invention will be described below with reference to the drawings.
Examples will be described. FIG. 1 is a block diagram of a ground unit check system showing an embodiment of the present invention, FIG. 2 is a diagram showing an example of a ground unit register ground unit data as a component of FIG. 1, and FIG. 3 is a diagram of FIG. It is the figure which imaged ledger ground child data. FIG. 4 is a diagram showing an embodiment of the recorded ground child data of the ground child, and FIG. 5 is a diagram illustrating the recorded ground child data of FIG. FIG. 6 is a flowchart showing an example of a procedure in the ground check system.

  In FIG. 1, a pre-created terrestrial ledger terrestrial data 1 and recorded terrestrial data 2 collected by a recording function of a security device mounted on a traveling train are input to a terrestrial data check system 3. . The terrestrial data check system 3 compares the terrestrial data of the ledger terrestrial data 1 and the recorded terrestrial data 2 and outputs abnormal data when there is abnormal data.

  FIG. 2 is an example of creating ledger ground element data that is a reference for detecting the ground element. The kilometer 4 inputs the kilometer of each ground child managed by the control chart or the like. The kilometer 4 is used as reference data for creating the ledger ground child data 1 on the ground child check system. The serial number 5 is a serial number on the register of the ground unit. As the ledger interval 6, the distance interval between the ground element and the ground element to be detected is input. In the detection section 7, the detection widths on the − side and the + side starting from the ledger interval 6 are input. As control data, information (information type, distance to stop signal, speed limit, etc.) to be compared with the recorded ground child data among the control information of the ground child 8 is input.

  FIG. 3 is an image of the ledger terrestrial data of FIG. 2, and shows the kilometer 4, serial number 5, ledger interval 6, detection section 7, and control data for the ground child 8.

  FIG. 4 shows an example of recorded ground data of the ground child. FIG. 5 is an explanatory diagram of the recording ground data of FIG. The recording time 9 is the time when the security device 10 receives (records) the ground element 8. The recording interval 11 is calculated by recording the interval between the received ground element and the ground element from the number of pulses input from the speed generator 12 to the security device 10 and the wheel diameter. In the control data, control information of the ground unit 8 is recorded.

  FIG. 6 is a flowchart showing a difference detection procedure in the ground check system. Ledger ground data 1 and recorded ground data 2 are input to the ground data check system (S101). Next, the serial number of the detection start ground element is designated (S102). Next, it is searched whether there is a next ground element (the ground element of the next serial number of the detection start ground element) in the ledger (S103). In step S104, it is determined whether there is a next ground element in the ledger. If there is no next ground element in the ledger, the ground element detection process is terminated. If there is a next ground element in the ledger in step S104, it is determined whether there is a record of ground data in the detection section of the ledger (S105). If there is no record of the ground element in the detection section of the ledger in step S105, the corresponding ground element is output (S106), and the process returns to the search for the next ground element in the ledger in step S103. If there is a record of ground data in the detection section of the ledger in step S105, it is determined whether the control data of the ledger (the contents of the teletext message) and the recorded control data (the contents of the telegram message) match. (S107). If the control data does not match in step S107, a data mismatch is output (S108), and the process returns to step S103. If the control data match in step S107, the process returns to the search for the next ground element in the ledger in step S103. The subsequent processing is repeated while there is a next ground element in the ledger, and when there is no next ground element to be searched in the ledger, the ground element detection process is terminated.

  As described above, according to the present invention, it becomes possible to detect abnormalities in the ground unit, poor installation, and abnormal setting data after making the best use of existing facilities, and safety of railway vehicles. It can contribute to improvement.
