Description

  The present invention relates to a test simulator for an electronic interlocking device that is an apparatus for a train operation management system, and a simulation method for an electronic interlocking device that performs a test using the simulator.

  The train operation management system is a system that is required to operate at all times in order to carry passengers and freight on the road during the day and to carry out maintenance work for the freight and on-site equipment such as track circuits and signal equipment at night. . In order to realize these, the control processing of the operation management system needs to be performed in real time, and the system is required to have very high reliability in terms of service provision and safety.

There are various forms to realize the train operation management system, but as one of the equipment elements, a device installed at the station in order to carry out appropriate route control for trains that arrive, depart, pass, and enter. As an electronic interlocking device. The electronic interlocking device is mainly composed of three devices.
The first is a route control device capable of controlling a route manually by an operation from a dedicated input terminal, in addition to automatically performing a route control for a main train and an entry / exit vehicle based on an implementation schedule.
The second is an interlocking logic unit that determines consistency with respect to control of field devices such as traffic lights, switchboards, track circuits, and the like.
The third is a signal equipment controller that directly controls field devices such as traffic lights, switchboards, track circuits, etc. corresponding to the course control from the course control device that is considered to be correct by the interlocking logic unit. Yes. These three devices are described in detail below.

  The route control apparatus has an automatic route control function and an information editing function for performing state information / control processing of on-site equipment between dedicated input terminals. Further, in order to ensure the operation rate, the system is configured as a double system, and when a failure of one system is detected, an independent operation is performed.

  The interlocking logic unit is composed of a triple system to improve safety and availability, and performs synchronous operation. Also, it has inter-system transmission and configuration control functions such as collation of processing results of each system and disconnection of abnormal systems. When an abnormal system is detected by collation processing, dual system operation is performed. In addition, the interlocking logic unit transmits / receives route control information, state facility status information, operation status information of its own device and other devices, etc. to / from the route control device and the field device between the field device controller and the signal device controller. It has a serial interface for sending and receiving data such as status information and control information.

  The signal equipment controller includes a field equipment control logic unit, an I / O unit, and a signal information control network. The field device control logic unit controls the field devices such as a traffic light, a switch, a track circuit, and the like based on the control information from the interlocking logic unit, the status information from the other signal device controller, and the like. The on-site equipment control logic unit and the I / O unit are configured in a duplex system, and when a failure in either system is detected, an independent operation is performed. When the master system of the field device control logic unit detects an abnormal stop of the slave system, it restarts the slave system from the master system.

  Data communication between these three devices uses the token bus method between the route control unit and the interlocking logic unit, and is used for control of the interlocking logic unit and route control unit, and communication of display data and intersystem verification data. Has been. An optical loop composed of a double system is used between the interlocking logic unit and the signal device controller.

  At present, in the electronic interlocking device having the above-described configuration, it is recently performed to update the interlocking logic unit and the signal device controller due to aging of the equipment. When updating the interlocking logic unit and the signal device controller that constitute the electronic interlocking device, it is possible to transmit at higher speed than the existing network between the route control device and the interlocking logic unit and between the interlocking logic unit and the signal device controller. A network of a general-purpose high-speed transmission standard such as Ethernet (trademark) is being applied.

  The existing electronic interlocking device test requires testing in the situation where the route control device, interlocking logic unit, signal device controller, and on-site equipment equivalent to the station to be installed are prepared because of the required high reliability. Is done. However, signal device controllers and a wide variety of field devices are produced by various manufacturers. Accordingly, enormous costs are incurred in preparing an environment equivalent to the actual machine, and space is required to maintain the environment. In addition, it is necessary to reconstruct the station environment for each replacement project, and in that case, there are a great number of problems such as costs for arrangement of insufficient facilities and environment construction.

Further, as described above, since the existing electronic interlocking device is composed of products of various manufacturers, there is a problem that communication protocols are different and it is difficult to manufacture a general-purpose simulator.
Patent Document 1 describes a technique for performing simulated running of a train with a simulator and performing a test with a train operation management device.

JP 2000-16295 A

  A major factor in manufacturing the test apparatus is the communication protocol between the route control device and the electronic interlocking device. In many cases, the existing electronic interlocking device adopts a protocol unique to each company as a communication protocol. In order to simulate this, it is necessary to prepare hardware including firmware conforming to the communication protocol of each company. In other words, it is necessary to produce dedicated simulators for the number of models to be simulated, and although technically possible, there is no cost advantage and abandonment has been abandoned. For this reason, an actual machine is used in the normal test of the existing interlocking device, and a destructive test, etc., which is difficult to achieve in normal operation, is partially modified for the internal processing of the route control device for testing, and a pseudo abnormality test is performed. It was. This was a low level test from the viewpoint of real machine equivalence. In addition, remodeling part of the internal processing of the route control device for testing has a considerable risk in terms of software destruction due to correction errors and the credibility of test results. From the viewpoint of product quality and reliability. It was not enough.

When a test apparatus is realized by the conventional technique, a method of acquiring data using a capture function of a general-purpose network analyzer, editing the data, and outputting pseudo data can be considered as the means. Such a technique is also applied to the simulator described in Patent Document 1.
In this conventional method, the course control device receives the information on the field device control from the interlocking logic unit, and receives the data from the interlocking logic unit once in a series of processes for performing the route control for the field device control, and converts it into the data. After editing, transmission to the route controller is performed. Data reception and transmission can be performed only in a discontinuous process because the serial number cannot be automatically updated when the serial number check in the data transfer is performed.
In addition, when this conventional method is used for a new electronic interlocking device, it is not possible to perform quality evaluation for network communication due to the use of a high-speed transmission line such as Ethernet between the route control device and the interlocking logic unit. Therefore, a function for performing continuous transmission is required. For this reason, in order to simulate an abnormality processing test at the same level as an online device using a test device, it is necessary to manually input a meaningful continuous packet in a short time, which is practically impossible. there were.

  In the conventional method described above, the type of data acquired by the capture function cannot be determined. However, since the electronic interlocking device is separated from facility information data, interlocking logic unit data, and abnormality information data, it is necessary to classify the data in order to perform an appropriate test. Was not done.

FIG. 6 and FIG. 7 show an example of inspection by a conventional method performed without using a simulator.
In the example of FIG. 6, in a system composed of an interlocking logic unit 81, a route control device 82 and a monitor 83, the data d11 is sent from the interlocking logic unit 81 to the route control device 82, so that the route control device 82 monitors the data. It is assumed that the display data d12 is sent to 83. Here, when the route control device 82 is a machine to be inspected and the route control device 82 has a function whose operation is desired to be tested, the simulation is performed by directly rewriting the data d11 output from the interlocking logic unit 81.

In the case of the inspection method shown in FIG. 6, it is necessary to directly rewrite the necessary portion of the data that is an enumeration of numbers, and there is a high possibility that erroneous rewriting is performed, and there is a possibility that a correct test cannot be performed.
Further, when the interlocking logic unit 81 is used, there is a problem that abnormal data cannot be transmitted to the route control device because the processing in the interlocking logic unit works.

In the example of FIG. 7, in the case of a system composed of a route control device 91 and a monitor 92 that are inspection target machines, data handled by the route control device 91 is directly rewritten and supplied from the route control device 91 to the monitor 92. This is an example in which the inspection is performed with the data d21.
In the case of the example of FIG. 7 as well, as in the example of FIG. 6, it is necessary to directly rewrite the necessary portion of the data that is a sequence of numbers, and there is a high possibility that erroneous rewriting will be performed, and a correct test may not be possible. There was sex.
In addition, since the test is not performed by receiving data from the interlocking logic unit which is the equipment to be updated, there is a possibility that the test is not completely consistent with the situation of the field facility, which is not preferable.

  An object of the present invention is to provide a simulator that realizes an appropriate test for an electronic interlocking device as a means for solving the above-described problem, and even when connected by a transmission line in which general-purpose high-speed communication is performed, a test equivalent to the use of an actual machine Is to realize.

The present invention relates to a signal device controller that controls field devices related to train operation, an interlocking logic unit that determines the consistency of control of the signal device controller, and a route control device that controls the signal device controller via the interlocking logic unit. And applied to a simulator for testing an electronic interlocking device.
As a test simulator, field equipment status data, linkage logic section status data and abnormality information data are received from the logic linkage section via the transmission line of the transmission standard, and each received data is held and held. A transmission process is performed to transmit each data to the route control device. Then, when holding the data received by the test simulator, the protocol sequence number given in the transmission standard is held, and when the test simulator performs simulation for the route control device, the held protocol sequence number is stored. Each stored data is transmitted in the order according to the order.

  According to the present invention, continuous data transmission that continuously transmits data state changes even when connected using a general-purpose high-speed transmission line such as Ethernet, which was impossible in a conventional electronic interlocking device test. Functions can be obtained and appropriate tests corresponding to equipment renewal can be performed.

Hereinafter, an example of an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a diagram showing an example of the overall configuration of the system according to the present embodiment.
As shown in FIG. 1, the electronic interlocking device 10 includes a signal device controller 11, a interlocking logic unit 12 that determines the consistency of control by the signal device controller 11, and the signal device controller 11 via the interlocking logic unit 12. And a route control device 13 for controlling. A monitor 14 for displaying a control state and the like is connected to the route control device 13.

The signal equipment controller 11 directly controls various on-site facilities related to train operation. In the example of FIG. 1, control of a plurality of switching devices 1 a to 1 n, control of a plurality of landing points 2 a to 2 n at each station, control of a plurality of levers 3 a to 3 n, and the like are performed. The example of FIG. 1 is an example, and there are other on-site facilities controlled by the signal device controller 11.
For data transmission between the signal device controller 11 and the interlocking logic unit 12 and data transmission between the interlocking logic unit 12 and the route control device 13, general-purpose transmission standards called Ethernet (trademark) are adopted, respectively. It is. This transmission standard is a LAN standard capable of bidirectional data communication at a relatively high speed such as 10 Mbps, and is widely used for connection between a computer device and its peripheral devices. In the following description, the Ethernet transmission standard applied in the present embodiment is simply referred to as a LAN standard.

Here, in the case of this example, the course control device 13 is used as an inspection target machine. For example, the signal device controller 11 and the interlocking logic unit 12 are updated to check whether or not the route control device 13 can correctly control the updated signal device controller 11 and the interlocking logic unit 12.
For this purpose, as shown in FIG. 1, a simulator 100 is connected between the interlocking logic unit 12 and the course control device 13. The simulator 100 is configured, for example, by installing a dedicated software (program) for simulator on a general-purpose computer device. The simulator 100 is also connected by Ethernet, and the interlocking logic unit 12 and the route control device 13 are connected. Data can be received and transmitted to them.
Then, the simulator 100 simulates the operation of the signal device controller 11 and the interlocking logic unit 12, and performs the same operation as the case where the signal device controller 11 and the interlocking logic unit 12 exist for the route control device 13. Let When the test is performed using the simulator 100, the interlocking logic unit 12 and the signal device controller 11 may be omitted.

Next, with reference to FIG. 2, the structure seen from the function of the simulator 100 comprised with a computer apparatus is demonstrated.
As shown in FIG. 2, the interlocking logic unit 12 and the interlocking control device 13 are connected via a LAN 16, and the simulator 100 is also connected to the interlocking logic unit 12 and the interlocking control device 13 via a LAN 17 so as to be communicable. . The interlocking logic unit 12 and the signal equipment computer device 11 are also connected by a LAN 15.

  The station equipment data reading unit 101 of the simulator 100 is a function for reading the configuration of the field equipment for each station and simulating the configuration of the signal equipment controller 11 in the simulator 100. In the simulator 100, the station equipment data used for this function is basically manufactured so that the actual data in the existing electronic interlocking device can be used. For this reason, it is possible to simulate other station facilities only by exchanging the station facility data, and it is possible to greatly reduce the time required for preparing the test environment for field equipment. As will be described later with reference to FIG. 5, the prepared station equipment can be easily switched.

The simulator 100 handles settings adapted to the traffic field device communication middleware to be used in order to enable communication between the route control device 13 and the linkage logic unit 12, and between the route control device 13 and the linkage logic unit 12. A communication middleware reception data unit 102 is prepared for receiving data. The data received by the communication middleware reception data unit 102 is once stored in the communication middleware reception data unit 111 in the data storage unit 110, and the stored data is called and used by the function of the data reception unit 103.
The data receiving unit 103 has a function of calling data from the communication middleware reception data unit 111 in the data storage unit 110 and performing editing for saving in the simulator 100. At this time, the received data is roughly classified into two types. The first type is stored in the received data unit 113 as received data, and the second type is stored in the received data management information unit 112 as received data management information. Received data is handled as facility information data, interlocking logic state data, and error information data. Received data management information is a file that manages the data reception time, saved file number, file size, and received data file name as a list. Point to. The communication middleware reception data unit 102 and the data reception unit 103 are instructed to start and stop by the reception processing management unit 104. This instruction is given by an operator input from an input unit (not shown).

  The reception data transmission unit 105 has a function of editing and transmitting data in order to transmit the reception data called from the reception data unit 113 or the reception data management information unit 112 in the data storage unit 110 to the electronic interlocking device 10. . Simultaneously with the transmission, the transmitted data is stored in the transmission data unit 114 in the data storage unit 110 as transmission data.

The facility information editing / transmitting unit 106 is roughly classified into six types by the received data transmitting unit 105, and the simulator 100 according to the present embodiment can edit five types.
The first type of data that can be edited is called a basic header and includes a function code, a loop number, a sub function code, a transmission source CPU number, a block number, the number of blocks, and a text length. These basic headers are based on those defined in the LAN standard.
The basic header handles information necessary for data transmission / reception, and the simulator 100 can edit all the elements of the basic header. Thus, by setting an abnormal value in the element of the basic header and handling it as transmission data, it becomes possible to perform an abnormality test on the function of the communication logic unit 12 for communication of data transmission / reception information.

  The second type of data that can be edited is called a transmission management part, and includes a control cycle, a protocol serial number, a reception time, and a transmission source CPU number. The transmission management part manages the order of received data, and the simulator 100 of this embodiment can edit all the elements of this transmission management part. Thus, by setting an abnormal value or a fixed value for the time and the protocol serial number, it is possible to perform a function abnormality test on the order of the received data of the interlocking logic unit 12.

  The third type of data that can be edited is called equipment information. Signal equipment controller, interlocking coupling device, NKR (turning device localization side display), RKR (switching device reverse side display), TR (track circuit of the track circuit) In-line display), external conditions, and HR (signal status display). The facility information is control information of the field device, and simulates the same state as when the actual field device does not exist without preparing an actual machine. In the simulator 100 of the present embodiment, all the elements of the facility information can be edited. Thus, by setting an abnormal value in the element of the facility information and handling it as transmission data, it is possible to perform an abnormality test on the consistency of control of the field device, which is the main function of the interlocking logic unit 12.

  The fourth type of data that can be edited is called route reservation information and indicates signal route information. In the simulator 100 of the present embodiment, it is possible to edit the traffic signal route state information. As a result, an abnormal value can be set for the function that performs consistency of the route reservation of the interlocking logic unit 12 by setting an abnormal value in the route reservation information and treating it as transmission data.

  The fifth type of data that can be edited is called various states, and includes a lever setting state, an inter-station trouble state, track circuit tracking, track circuit reservation, switch reservation information, other equipment information, and a sum check value. The various states are state information indicating what kind of work situation the field device is controlling. In the simulator 100 according to the present embodiment, the lever setting state, the inter-station trouble state, the track circuit tracking, and the switch It is possible to edit five elements of reservation information and other equipment information. As a result, it is possible to perform a function abnormality test on the consistency of the control information setting with respect to the work state of the field device of the interlocking logic unit 12.

The interlocking logic state editing / transmission unit 107 is roughly classified into five types by the reception data transmission unit 105, and the simulator 100 can edit three types.
The first type is a basic header and the second type is a transmission management part, which is the same as the processing of the basic header and the transmission management part described above. The third type is system configuration control data, which includes a 1-system interlocking state, a 2-system interlocking state, a 3-system interlocking state (preliminary), a control cycle, and an external device state. The system configuration control data includes setting information related to configuration control of the interlocking logic unit 12, and the simulator 100 can edit all elements. Accordingly, an abnormal test of the function for the configuration control of the interlocking logic unit 12 can be performed by setting an abnormal value in the system configuration control data and handling it as transmission data.

  The abnormality information editing / transmitting unit 108 is roughly classified into five types by the received data transmitting unit 105, and the simulator 100 can edit four types. The first type is a basic header and the second type is a transmission management part, which is the same as the processing of the basic header and the transmission management part described above. The third type is called alarm output information and includes a registration block, an error code, detailed information, a control cycle, and an alarm output time. In the simulator 100, all elements can be edited. Thus, an abnormality test for the function for alarm output is possible. The fourth type is called system monitoring information and includes the number of registered blocks, error code, detailed information, control cycle, and monitoring information acquisition time. In the simulator 100, all elements can be edited. As a result, it is possible to perform an abnormality test on the function of the system monitoring information.

The trace unit 109 includes a station facility data reading unit 101, a communication middleware reception data unit 102, a data reception unit 103, a reception processing management unit 104, a reception data transmission unit 105, a facility information editing / transmission unit 106, and an apparatus state editing / transmission unit. 107, the abnormality information editing / transmission unit 108 and the trace unit 109 perform processing for displaying error information when an error occurs. The error information indicates the time when the error occurred, the trace type, the function type, and the trace contents, and the display is performed on a display unit (not shown) or the monitor 14 provided in the simulator 100 itself.
There are four types of traces, and processing traces, abnormal traces, detailed traces, and buffer information are selected and displayed as items to be traced. The function type indicates which process caused the error. Common process, definition file, system transaction, interlocked logic reception, facility information reception, error information reception, interlock logic transmission, facility information transmission, error information It is classified into 10 types of functions of transmission and trace processing.

Next, specific processing in the simulator 100 of the example of the present embodiment will be described using the processing operation diagram of FIG.
Each reception function and transmission function to be described below with reference to FIG. 3 can be received or transmitted with the electronic interlocking device 10 side via the communication middleware 203.
After the simulator 100 is activated, the communication middleware reception data unit function 204 and the data reception function 207 are activated from the reception processing management function 205 in order to activate the communication middleware reception data unit 102 and the data reception unit 103. Since the reception processing management function 205 indicates a start or stop state, the reception process management function 205 can update the period to cope with a change in the reception state. The activated communication middleware reception data unit function 204 performs processing for receiving communication data at a constant cycle. If there is received data at this time, it is stored as the reception buffer 206. Then, the data reception function 207 activated by the reception processing management function 205 confirms the presence or absence of the reception buffer 206 at regular intervals. If reception data exists, the reception data is read and simultaneously received data 208 is received. The received data management information is stored in the received data management information display and the received data management information 209.

  The data stored in the reception data 208 and the reception data management information 209 is used by the reception data transmission function 210. The reception data transmission function 210 can arbitrarily transmit reception data in the data received by the simulator 100. There are three types of data that can be selected: facility information data, interlocking logic section data, and abnormality information data. The functions of the reception data transmission function 210 include setting the number of transmissions and setting a transmission interval. The data transmitted by the received data transmission function is stored in the transmission data storage unit 218.

  Transmission data can be individually edited for facility information data, interlocking logic section data, and abnormality information data. When the facility information editing / transmission function 211 is activated, the above-described basic header, transmission management unit, facility information, route reservation information, code response information, and a screen for performing various state states and editing are displayed. At this time, all elements of the basic header, all elements of the transmission management partial data, all elements of the code response information, and sum check values in various states are definition settings necessary for data communication. When starting up, it is assumed that data communication is possible, so it has an initial value. For all elements except for facility information, route reservation information, and sum check of various states, the initial value when the simulator 100 is started has a value indicating that no control is performed. As a result, when the simulator 100 is activated, it is possible to transmit the data relating to the facility information as transmission data without performing a value setting operation.

  For all elements except equipment information, route reservation information, and various status sum checks, an initial value file is created and read to transmit data with initial values including abnormal conditions set in advance. It is also possible. The transmitted data is stored in the transmission data storage unit 218, and it is possible to call data that is desired to be transmitted again later, and the called transmission data can be re-edited and transmitted. When the interlocking logic section editing / transmission function 212 is activated, the above-described basic header, transmission management section, system configuration control data, maintenance work response data, and sum value status and screen for editing are displayed. At this time, all elements of the basic header, all elements of the transmission management unit, all elements of the maintenance work response data, and the sum value are definition settings necessary for performing data communication. When the simulator 100 is started, Since it is assumed that data communication is possible, an initial value is given. Regarding the system configuration control data, the initial value when the simulator 100 is started has a value indicating that there is no problem in the configuration control. Thereby, at the time of starting the simulator, it is possible to transmit data relating to the interlocking logic unit 12 as transmission data without performing a value setting operation.

  The transmitted data is stored in the transmission data storage unit 218, and it is possible to call data that is desired to be transmitted again later, and the called transmission data can be re-edited and transmitted. When the anomaly information editing / transmission function 213 is activated, a screen for performing the above-described basic header, transmission management unit, alarm output information, system monitoring information, and sum value status and editing is displayed. At this time, all elements of the basic header, all elements of the transmission management unit, and the sum value are definition settings necessary for data communication. When the simulator 100 is started, data communication is possible. Because it is assumed, it has an initial value. In the alarm output information and the system monitoring information, the initial value at the time of starting the simulator has a value indicating that there is no abnormality in the data. As a result, when the simulator 100 is activated, it is possible to transmit data relating to abnormality information as transmission data without performing a value setting operation. The transmitted data is stored in the transmission data storage unit 218, and it is possible to call data that is to be transmitted again later, and it is also possible to re-edit and transmit the called transmission data.

  Communication middleware reception data section function 204, reception processing management function 205, data reception function 207, reception data transmission function 210, facility information editing / transmission function 211, interlocking logic section editing / transmission function 212, abnormality information editing / transmission function When a process corresponding to an error defined in the program of the simulator 100 is performed during the process, the error information is managed by the trace function 214. Trace display / output is performed in a separate process so as not to affect the process of the output request source. The error output by each function is stored in the temporary save memory 215, and the trace writing process confirms whether there is trace data in the temporary save memory 215 at a constant cycle. When the trace data is stored in the temporary save memory 215, an error display process is performed and the storage processor 216 stores the trace data in the trace data storage unit 217. From the information displayed in this trace, it is possible to easily find an abnormal part of the received data or the processed data.

FIG. 4 is a diagram showing a flow of an inspection method using the simulator 100 according to the present embodiment.
As shown in FIG. 4, the content of data originally sent from the interlocking logic unit 12 to the route control device 13 is edited as necessary by the processing already described in the simulator 100, and the edited data D1 is The route control device 13 sends the corresponding display data D2 to the monitor 14 and displays the control result.

In this case, as compared with the conventional examples shown in FIG. 6 and FIG. 7, the operator does not directly correct the data itself, but the simulator 100 determines which value performs which control and edits it. As a result, the necessary simulation is performed correctly and the operability is greatly improved. In particular, the simulator 100 according to the present embodiment is realized by using a general-purpose computer device, so that the test area can be saved, the preparation time can be reduced, and the cost can be reduced. Furthermore, the data continuous transmission function that continuously transmits data state changes, which was impossible in the conventional electronic interlocking device test, and the transmission data is handled as an equivalent data type to the electronic interlocking device, and synchronous transmission is performed. The data synchronization transmission function and the data re-transmission function for storing the data and transmission data received in the past and enabling the transmission again can provide an effect of performing an advanced test of the electronic interlocking device.
In this embodiment, the system is connected by a specific LAN standard and communicates by a specific communication protocol. However, the simulator 100 can edit data conforming to the LAN standard, and is connected by a LAN. The system can be easily and properly tested.

In addition, by preparing data of a plurality of field facilities in the simulator 100 in advance and switching the data of the field facilities, it is possible to simulate the sites of various stations.
That is, for example, as shown in FIG. 5, a plurality of station equipment data 191, 192, 193... Are stored, the station equipment data to be used is switched by the switching unit 190, and applicable from the route control device 13 side. Function as if there is a station facility.
Each station equipment data 191, 192, 193 may be acquired from the signal equipment controller 11 (FIG. 1) connected to the actual field equipment, or may be obtained by an input of an operator.

In the above-described embodiment, the simulator and the electronic interlocking device are connected by the Ethernet LAN standard, but may be connected by a bus line of another general-purpose transmission standard.
The simulator is configured by installing software on a general-purpose computer device, but may be configured as a dedicated simulation device.
