Description

  The present invention relates to an ATS-P ground element state analyzing method and an ATS-P ground element state analyzing apparatus used in railways.

  ATS-P determines the planned stop point corresponding to the stop indication, tells the distance and gradient to the train from the ground, calculates the speed pattern from the momentary position on the car and the braking performance of the vehicle. This is a development of an automatic train stop device that performs speed check. The ATS-P ground unit is a device installed on the track, and sends data (telegram) to the ATS-P vehicle unit installed on the train when the train passes. Based on the received telegram data, the train controls the brakes and the like.

  The ATS-P ground child was introduced mainly on conventional lines mainly in the Tokyo metropolitan area, and the ATS-P (N) type has been planned to expand and expand to the suburbs for cost reduction. The ATS-P (N) type ground element is a part in which the presenting up function and the like and the information transmission function from the vehicle element to the ground element are omitted.

  Conventionally, it has been proposed that the ATS-P (N) type ground element itself has a telegram checking function (Patent Document 1). In addition, it has been proposed to provide a fault detection circuit on the ground side for detecting a fault of the ATS-P (N) type ground element and to transmit the detected fault to the vehicle (Patent Document 2).

  Furthermore, the on-board device stores in advance the reception order of the ground elements laid on the route, and compares it with the joining order actually exchanged between the on-board element and the ground element having the ID number while the train is running. Thus, it has been proposed to determine that the reception is abnormal when the order is different (Patent Document 3).

  In addition, the actual status of the current ATS-P ground unit can be monitored by telegram (running data) reception inspection once every six months by the inspection vehicle (East-i), or by manual installation once every two years. Checks including the above are carried out during the repair work.

  Since the current ATS-P (N) type ground element and the non-powered ground element used for speed limitation have no failure detection function, a new failure detection function is added to the ground element as shown in Patent Document 1. It is expensive to have.

  Further, as disclosed in Patent Document 2, it is difficult in terms of cost to provide a failure detection circuit on the ground side and transmit failure information on the vehicle.

  Furthermore, as shown in Patent Document 3, an ID number is assigned to the ground unit, the reception order is stored in advance in the on-board device, and the reception order received from the ground unit during actual traveling is verified on the ground side and The thing currently in use on the upper side of the vehicle cannot be used as it is, which is difficult in terms of cost. Moreover, the ID number to be used becomes a huge number.

  In addition, since the actual status monitoring of the ATS-P ground unit currently being performed is about once every six months or once every two years, it is desired to monitor the status a little earlier. In particular, with respect to a speed limiting ground element (non-powered ground element), if a double failure occurs during the inspection cycle, etc., there is a case where it becomes a dangerous event in which a speed limiting pattern does not occur in the vehicle, as will be described later in FIG. There is a situation that requires early detection and handling of defective grounding. Note that the same speed limiting ground element is laid in the same position as a pair for safety, but the double failure means that the pair of ground elements both fail.

  FIG. 16 shows the speed limit pattern generation. As shown in FIG. 16A, the vehicle 51 is provided with an on-board device 52 and an on-board element 53, and above-ground elements 54 and 55 are laid on the route. The ground element 54 is a defective ATS-P ground element, and the ground element 55 is a normal ATS-P ground element. If the ground pieces 54 and 55 are non-powered ground pieces, the power is obtained from the transmission radio wave from the vehicle upper piece 53, the ground piece 55 transmits data (telegram) to the vehicle upper piece 53, and the on-board device 52 A speed limit pattern 56 as shown in FIG. 16C is generated based on the received message. The speed limit of the vehicle 51 is controlled by this speed limit pattern. Since the data cannot be received from the defective ground element 54, the on-board device 52 does not generate a speed control pattern as shown in FIG.

(Object of invention)
An object of the present invention is to provide an ATS-P ground element state analysis method and an ATS-P which can analyze the ground element state without changing the current ground element and the device on the upper side of the vehicle, and with less manpower. It is to provide a ground state analyzer.

In order to achieve the above object, the ATS-P ground unit state analyzing method of the present invention is created by arranging the data of a plurality of ATS-P ground units in the order in which they pass when one train travels.

Moreover, in order to achieve the said objective, the ATS-P ground unit state analysis apparatus of this invention was created by arranging the data of a plurality of ATS-P ground units in the order of passing when one train travels , Storage means for storing basic data including P numbers assigned numbers to the plurality of ATS-P ground elements in order from the traffic light for each traffic signal section, and received from the ATS-P ground elements during traveling of the business vehicle from accumulated data of the running conditions including accumulated the P number Te, generating means for generating an analysis on a vehicle data including the P number, and absolute position in associate on data the basic data and the analysis vehicles Setting means for setting an ATS-P ground element having the same telegram of the ATS-P ground element of the basic data and the on-vehicle data for analysis as a reference ground element, and a P number of the reference ground element The And collating means for then sequentially collating whether the basic data of the P number and P number of the data the analysis wheel matches the criteria, the same P on the data the analysis wheel relative to P number of the basic data An ATS-P ground element state analyzing apparatus comprising: a detecting means for detecting a ground element having no number as a defective ground element; and a display means for displaying a state analysis result including at least the detection of the defective ground element. When the collating means does not match the P number of the basic data and the P number of the on-vehicle data for analysis, the mutual relationship between the P number of the basic data and the P number of the on-vehicle data for analysis is determined. It is characterized in that a ground fault and a deficiency in basic data are determined by collating with each other.

  According to the present invention, it is possible to analyze the state of the ground unit without changing the current ground unit and the device on the upper side of the vehicle, and with less manpower.

  Here, the P number is defined. Numbers are assigned to the ground elements P1, P2, P3,... Shown in FIG. In addition, the number 0 and F are assigned to the speed limiting ground element laid before the location where the speed of the train is limited for each speed limiting section in order from the speed limiting section. These terrestrial numbers are assigned to the 9th to 12th bits of the terrestrial telegram, and these numbers are hereinafter referred to as P numbers.

  The mode for carrying out the present invention is as shown in the following examples.

  FIG. 1 shows an outline of an embodiment according to the present invention for analyzing the state of the ATS-P ground unit. The business vehicle 1 is provided with an onboard device 2, an onboard child 3, and an ATS-P recording device 4, and on the route, ground children P1, P2, P3,. The ground elements P1 and P3 are normal ATS-P ground elements, and the ground element P2 is a defective ATS-P ground element. If the ground element P1 is a non-powered ground element, the power is obtained from the transmission radio wave from the vehicle upper element 3, and the ground element P1 transmits data (including P number and message) to the vehicle upper element 3 to The upper device 2 generates a speed limit pattern 56 as shown in FIG. 16C based on the received data. Data received from the ground unit P1 or the like is stored as stored data 5 in the ATS-P recording device 4.

  Reference numeral 6 denotes a personal computer (hereinafter referred to as a PC) in which software for a ground element state analysis method is installed. The stored data 5 is obtained from the ATS-P recording device 4 in which the traveling state data including the P number and the received telegram is recorded from the ground children P1, P2, P3. The PC 6 extracts from the stored data 5 data necessary for the ground unit state analysis (this data is referred to as analysis vehicle data 7). Data arranged in a permutation each time a ground unit is installed based on the ATS-P control chart and the equipment management system by the analysis worker (this data is referred to as basic data 8) is stored in the PC 6. The PC 6 collates the basic data 8 with the on-vehicle data 7 for analysis. When the on-vehicle data for analysis 7 corresponding to the basic data 8 is recorded, the ground element existing in the on-vehicle data for analysis 7 with respect to the basic data 8 is detected as a good ground element. When the on-vehicle data 7 for analysis corresponding to the basic data 8 is not recorded, a ground element that does not exist in the on-vehicle data 7 for the basic data 8 is detected as a defective ground element. Such state analysis is performed for each P number, and the result is displayed. In the case of this display, it may be a display of a state analysis result including at least detection of a defective ground element.

  FIG. 2 is a flowchart showing the operation of the ground element state analyzing method or the ground element state analyzing apparatus in more detail. In step S101, the analysis worker uses the PC 6 to create the basic data 8 manually in the order of train travel based on the ATS-P control chart and the like, and stores it in the PC 6. The image of the basic data 8 is as shown in FIG. 5 and is arranged according to the P number. The basic data 8 may be created by another PC and the result may be stored in the PC 6.

  In step S <b> 102, the PC 6 generates the on-vehicle data for analysis 7 by extracting it from the accumulated data 5. The accumulated data 5 that is the basis of the on-vehicle data 7 for analysis is binary-format data that records 150 bytes of train running state every 0.2 seconds, from which the data shown in FIG. Perform extraction. The year / month / day / hour / minute / second data 9 is used for the received telegram time of the on-vehicle data 7 for analysis, and the distance data 10 between the ground units is used about a kilometer of the on-vehicle data 7 for analysis. The ground unit received telegram data 11 to 14 are used for the received telegram of the on-vehicle data 7 for analysis, and the train information data 15 is used for the file name when saved in the csv file of the PC 6.

  FIG. 4 is a flowchart of a specific example of generating the on-vehicle data 7 for analysis. In step S201, the stored data 5 is read 150 bytes (data every 0.2 seconds). In step S202, data is stored in the memory of the PC 6 for each change in received message. In step 203, it is determined whether or not the recording time is empty for about 2 seconds. These 2 seconds are the time to see if the train has ended. If it is vacant, the process proceeds to step S204. If it is not vacant, this flow ends.

  In step S204, the data (11 in FIG. 3) of the ground reception telegram 1 system AM1 is adopted as the on-vehicle data 7 for analysis from the data stored in the memory of the PC 6. When there is no recording, data of other systems (12 to 14 in FIG. 3) is adopted. In step S205, it is determined whether the number of adjusted data is equal to or greater than a set value. This is to eliminate the data in the short section. If the number of adopted data is equal to or greater than the set value, the process proceeds to step S206 and is saved in the csv file of the PC 6. If it is less, the process proceeds to step S207, and the data stored in the memory of the PC 6 is discarded. The generated image of the on-vehicle data 7 for analysis is as shown in FIG. 5 and is arranged in the order of running and recording.

  When the generation of the on-vehicle data 7 for analysis ends, the process returns to FIG. 2 and proceeds to step S103. In this step, a reference ground element is set. The reference ground element is a ground element that is an absolute position when the on-vehicle data 7 for analysis is associated with the basic data 8. In order to collate the analysis vehicle data 7 with the basic data 8, it is necessary to first match the ground element positions of the basic data 8 and the analysis vehicle data 7, and the PC 6 automatically selects the reference ground element. Determine the position. The data of the ground element whose P number is [0] or [F] (this ground element is referred to as an analytical ground element) is likely to be a unique telegram. The reference ground element that is the absolute position is set, and the P number of the basic data 8 is compared with the P number of the on-vehicle data 7 for analysis, and the basic data 8 and the on-vehicle data 7 for analysis are collated. ing. In FIG. 5, a ground element having a P number [0] and the same registered message and received message is set as a reference ground element.

  However, since the analysis ground element does not have a unique message, it is likely that the wrong place is regarded as the reference ground element. Therefore, there are two methods: the method of setting the reference ground element from one analysis ground element and the method of setting the reference ground element from two analysis ground elements to increase the probability of being unique. The ground unit is set so that the reference ground unit can be set without any problem. FIG. 6 shows a method for setting a reference ground element from two analytical ground elements having P numbers [0] and [F]. In the present invention, at least one of the above two methods is executed.

  FIG. 7 is a flowchart showing a method for setting a reference ground element from one analysis ground element by the PC 6. In step S301, processing for setting a reference ground element from one analysis ground element is started. In step S302, a basic data file to be collated and an on-vehicle data file for analysis are selected. In step S303, the registered telegram of the analysis ground element is extracted from the selected basic data 8. In step S304, among the extracted registered telegrams for analysis, the special telegrams and the same telegrams are deleted.

  In step S305, the received telegram of the analysis ground element is extracted from the selected on-vehicle data 7 for analysis. In step S306, of the extracted received telegrams for the analysis ground element, the special telegram ground element and the same telegram ground element are deleted. In step S307, a part where the registered telegram of the extracted ground data for the basic data 8 and the received telegram of the analytical ground element of the on-vehicle data for analysis 7 are the same is searched and set as a reference ground element.

  In step S308, it is determined whether or not the reference ground element has been set. If the reference ground element has been set, the process proceeds to step S309 to proceed to the collation process using the P number. If it cannot be set, the process proceeds to step S310 to stop the process.

  FIG. 8 is a flowchart showing a method for setting a reference ground element from two analysis ground elements by the PC 6. In step S401, a process of setting a reference ground element from the two analysis ground elements is started. Steps S402, S403, S406, and S410 to S412 are the same as steps S302, S303, S305, and S308 to S310 in FIG.

  In step S404, among the registered telegrams for analysis extracted from the basic data 8, the special telegrams and the ground elements in the station are deleted. In step S405, if the pair of analysis ground elements adjacent to each other in the extracted registered messages of the analysis ground element are the same, the contents are deleted.

  In step S407, the special telegram ground element is deleted from the analysis telegram received telegrams extracted from the on-vehicle data 7 for analysis. In step S408, if the received pair of analysis ground elements in the extracted analysis ground element is the same, the contents are deleted. In step S409, a location where the two registered telegrams of the extracted ground data for the basic data 8 and the received telegram of the ground data for analysis of the on-vehicle data for analysis 7 are the same is searched for and set as a reference ground unit. In the example of FIG. 6, two device names P100-1 and P100-2 and two device names P200-1 and P200-2 are candidates for the reference ground element. In that case, the direction closer to the starting point (the starting direction, that is, the upper side in FIG. 6) is set as the reference ground element. However, there is no problem even if the direction closer to the end direction (end direction, that is, the lower side in FIG. 6) is selected.

  Returning to FIG. 2, after the reference ground element is set, the process proceeds to step S104. Here, it is determined whether the permutation of the P number of the basic data 8 and the permutation of the P number of the on-vehicle data for analysis 7 are the same with respect to the ground element at the terminal end from the reference ground element. In other words, if the P numbers of both data match, the link (associates both data) is made, and if they do not match, the mutual relationship between the basic data 8 and the on-vehicle data for analysis 7 is shifted little by little. See if they match. If they match, the process proceeds to step S106 through step S105, and is detected as a good ground element. If not, the process proceeds to step S107 and is detected as a defective ground element. The basic data 8 that is not in the on-vehicle data 7 for analysis is referred to as idling, which means that the ground unit does not transmit data. What is not in the basic data 8 but in the on-vehicle data 7 for analysis is referred to as springing, which means that the basic data 8 is incomplete.

  In step S108, it is similarly determined whether the permutation of the P number in the basic data 8 and the permutation of the P number in the on-vehicle data for analysis 7 are the same for the starting ground element from the reference ground element. The ground element state analysis is performed as described above. In step S109, the state analysis result is displayed on the display unit of the PC 6.

  Specific examples of how to collate using P numbers will be described with reference to FIGS. After setting the reference ground element in step S501 of FIG. 9, the process proceeds to step S502. Here, the on-vehicle data 7 for analysis is viewed in the order in which the basic data 8 are arranged from the set reference ground element. In step S503, it is determined whether the basic data 8 or the analysis data 7 has been checked to the end. If the analysis is just started, it is of course no, so the process proceeds to step S504. If the P numbers of the basic data and the on-vehicle data for analysis coincide with 2 → 2 or 1 → 1 as shown on the left side of FIG. 10, the two are linked in step S505. In step S506, the correction value of the reference data and the correction value of the on-vehicle data for analysis are each set to zero. The correction value will be described later. In step S507, the primary data of each of the basic data and the on-vehicle data for analysis is checked. Also, that location is used as a reference point. On the left side of FIG. 10, 5 → 2 is the reference point.

  If the P numbers do not match in step S504, the process proceeds to step S508. First, the process proceeds to step S509 of the (b) pattern. Here, only the basic data is advanced by one to check the data. As shown in the center of FIG. 10, the P number is advanced from 5 to 4 and 4 → 2 is checked. Since 4-2 does not match, the process proceeds to step S510 of pattern (c) through steps S503 → S504 → S508. Here, the basic data is returned to the reference point, and the data on the vehicle for analysis is advanced by one to check the data. As shown in the right side of FIG. 10, the P number of the basic data is returned from 4 to 5, the on-vehicle data for analysis is advanced by 1 from 2 to 1, and 5 → 1 is checked. Since there is no match in 5-1, the process proceeds to step S511 of the pattern (d) through steps S503 → S504 → S508. Here, the correction value of the basic data is +1. In step S512, the basic data and the on-vehicle data for analysis are returned to the reference point, and the basic data is advanced by the correction value + 1 to check the data.

  As shown on the left side of FIG. 11, the P number of the basic data is incremented by 1 to advance from 5 to 4, the on-vehicle data for analysis is returned to 2, and 4 → 2 is checked. Since 4-2 does not match, the process proceeds to step S509 of pattern (b) through steps S503 → S504 → S508. Here, only the basic data is advanced by one to check the data. As shown in the center of FIG. 11, the P number is incremented by 1 from 4 to 3, and 3 → 2 is checked. Since 3-2 does not match, the process proceeds to step S510 of pattern (c) through steps S503 → S504 → S508. Here, the basic data is returned to the reference point, and the correction value is incremented by one, the on-vehicle data for analysis is advanced by one, and the data is checked. As shown in the right side of FIG. 11, the P number of the basic data is returned from 3 to 4, the on-vehicle data for analysis is advanced by 1 from 2 to 1, and 4 → 1 is checked. Since 4-1 does not match, the process proceeds to step S513 of the pattern (e) through steps S503 → S504 → S508. Here, the correction value of the on-vehicle data for analysis is set to +1. In step S514, the basic data and the analysis vehicle data are returned to the reference point, and the analysis vehicle data is advanced by the correction value + 1 to check the data.

  As shown on the left side of FIG. 12, the P number of the on-vehicle data for analysis is incremented by 1 to advance from 2 to 1, the basic data is returned to 5, and 5 → 1 is checked. Since there is no coincidence in 5-1, the process proceeds to step S509 of pattern (b) through steps S503 → S504 → S508. Here, only the basic data is advanced by one to check the data. As shown in the center of FIG. 13, the P number is incremented by one from 5 to 4, and 4 → 1 is checked. Since 4-1 does not match, the process proceeds to step S510 of the pattern (c) through steps S503 → S504 → S508. Here, the basic data is returned to the reference point, and the data on the vehicle for analysis is advanced by one to check the data. As shown in the right side of FIG. 12, the P number of the basic data is returned from 4 to 5, the on-vehicle data for analysis is advanced by 1 from 1 to 8, and 5 → 8 is checked. Since no match is found at 5-8, the correction value of the basic data is set to +2 at step S511. In step S512, the basic data and the on-vehicle data for analysis are returned to the reference point, and the basic data is advanced by the correction value +2 to check the data.

  As shown on the left side of FIG. 13, by incrementing the P number of the basic data by +2, the process proceeds from 5 to 3, the on-vehicle data for analysis is returned to 2, and 3 → 2 is checked. Since 3-2 does not match, the process proceeds to step S509 of pattern (b) through steps S503 → S504 → S508. Here, only the basic data is advanced by one to check the data. As shown in the center of FIG. 13, the P number is incremented by 1 from 3 to 0, and 0 → 2 is checked. Since 0-2 does not match, the process proceeds to step S510 of the pattern (c) through steps S503 → S504 → S508. Here, the basic data is returned to the reference point and advanced by the correction value +2, and the analysis on-vehicle data is advanced by one to check the data. As shown on the right side of FIG. 14, the P number of the basic data is returned from 0 to 3, the on-vehicle data for analysis is advanced by 1 from 2 to 1, and 3 → 1 is checked. Since there is a mismatch in 3-1, the process proceeds to step S513 of (e) pattern through steps S503 → S504 → S508. Here, the correction value of the on-vehicle data for analysis is set to +2. In step S514, the basic data and the analysis vehicle data are returned to the reference point, and the analysis vehicle data is advanced by the correction value +2 to check the data.

  As shown in the left side of FIG. 14, the P number of the on-vehicle data for analysis is incremented by +2 to advance from 2 to 8, the basic data is returned to 5, and 5 → 8 is checked. Since it is not coincident with 5-8, the process proceeds to step S509 of the pattern (b) through steps S503 → S504 → S508. Here, only the basic data is advanced by one to check the data. As shown in the center of FIG. 14, the P number is advanced from 5 to 4 and 4 → 8 is checked. Since 4-8 does not match, the process proceeds to step S510 of pattern (c) through steps S503 → S504 → S508. Here, the basic data is returned to the reference point, and the data on the vehicle for analysis is advanced by one to check the data. As shown in the right side of FIG. 14, the P number of the basic data is returned from 4 to 5, the on-vehicle data for analysis is advanced by 1 from 8 to 7, and 5 → 7 is checked. Thereafter, the correction value is incremented by +1 until the P numbers match.

  When the collation of the end direction between the basic data and the on-vehicle data for analysis ends, the process proceeds from step S503 to step S515, and collation from the reference ground element to the starting point is started. When this collation is completed, the process proceeds to step S516, and the collation process using the P number is terminated.

  FIG. 15 is an example showing items of the state analysis result display. After the collation processing by the P number, the background color is changed on the software for the collated data as shown in FIG. 15, and the state analysis result is displayed by symbols when the totaling result is output by the csv file.

  In this embodiment, on-vehicle data for analysis is generated from the accumulated data of the running state accumulated during the traveling of the business vehicle, and assigned to each ATS-P ground element included in the basic data and the on-vehicle data for analysis. Since the reference ground element serving as a reference for collation is set by the P number, there is no need to change the current ground element and the vehicle upper device. In addition to basic data creation, storage of basic data, generation of on-vehicle data for analysis, reference ground element setting, collation between basic data and on-vehicle data for analysis, detection of defective ground elements, status analysis results Since the display is automatically performed, it is possible to analyze the ground state by reducing manpower.

  The present invention can be applied not only to the ATS-P ground unit state analyzing method but also to the ATS-P ground unit state analyzing apparatus. In the ATS-P ground unit state analysis apparatus, the storage medium of the PC 6 corresponds to a storage unit that stores basic data of the present invention. The functional part of the PC 6 that executes Step S102 in FIG. 2 and Steps S201 to S207 in FIG. 4 corresponds to the generation means for generating on-vehicle data for analysis according to the present invention. The functional part of the PC 6 that executes step S103 of FIG. 2 selects a reference ground element that is a reference for collation based on the P number assigned to each ATS-P ground element included in the basic data of the present invention and the on-vehicle data for analysis.
