Description

  The present invention provides a train operation management system that enables software tests and evaluations to be performed in an environment equivalent to an online system when performing tests such as system update and verification in a train operation management system. The present invention relates to a test apparatus and a test method.

  A characteristic of the train operation management system is that it operates 24 hours a day 365 days a week. This is because the train continues to operate day and night every day. That is, once the system is operated, it is a system in which operations for maintenance, testing, replacement, etc. cannot be easily performed. For this reason, when conducting a test of a train operation management system that is online, there is no train operation called a train interval, or the current system stop / test system that is online within a short time of about 1 to 2 hours. Switch to / test system start / test / test system stop / switch to current system / current system start / sanity check. Because of such a test method, the actual test time that can be secured at one test is several tens of minutes. When a large-scale test is required, such as when replacing a train operation management system, the replacement work can be performed only after repeating these tests several tens of times.

As a system test method for newly developing a train operation management system with such characteristics, a simulator that simulates the system and on-site equipment at the test stage in the factory where the system is being developed can be used. Conduct the test. After that, it is common to install the system at the site where the system is delivered. However, since it is impossible for the simulator to completely simulate the system conditions of the local field equipment, it is difficult to say that a highly accurate system test can be performed in the factory test.
For this reason, a field connection test is performed to perform a more accurate system test. In the field connection test, the field equipment is switched during several hours at night. Therefore, in order to check a huge amount of equipment, it takes several tens of days to test in small portions. After that, a test train is prepared and a test is performed by running the test train.
These are test methods in the new system. Since the new system is large in scale and has a preparation system for user budget, personnel, period, etc., a system for conducting these tests can be secured and sufficient testing is possible.

  On the other hand, there is an on-site parallel run method as a method for performing a system test independent of the accuracy of the simulator. This is a method of acquiring communication data from on-site equipment in a local operation system by a test system installed in the field. As a means for taking communication data from the local operation system into the local test system, a device that acquires the communication data directly from the local area network, such as a network analyzer, is used. As a feature of the parallel run method, there is a point that the system test can be performed all day without being restricted by the time between trains. In addition, because the communication data from the on-site equipment in the field operation system is directly acquired in the field test system, the control timing that cannot be reproduced by the simulator can be reproduced, and the accuracy under the system conditions equivalent to the field operation system System test can be performed.

As described above, in the parallel run test, the same communication as the local operation system can be reproduced by transmitting the communication data acquired from the local operation system to the test system. However, the communication data from the test system will affect the local operation system, the node of the local operation system will be modified to incorporate the communication data into the test system, and the application program related to communication will be changed or created. Necessary.
In order to solve this problem, the communication data of the local operation system is imported into the test system without affecting the train operation management system in operation, and the environment of the local operation system is simulated by the test system. A test method for realizing this test is presented.

  In Patent Literature 1, a train operation management system and a test system are connected via a data transfer device, and communication data from the train operation management system is transmitted to the test system only in one direction by this data transfer device, There is a disclosure about an example of a test method for blocking communication data from a test system to a train operation management system.

JP 2007-145156 A

Generally, when replacing the system, a test apparatus that secures the following two points is required.
(1) Ensuring equivalency with local operation (replacement target) system (2) Minimizing on-site adjustment period.
There are two types of system replacement. There are two types of replacement: batch replacement for replacing the entire system at once, and partial replacement for sequentially replacing some devices such as terminals. Since the bulk replacement is large in accordance with the new system, the preparation system for the user's budget, personnel, period, etc. is in place, and the conventional technology such as the parallel run method described above can be used. However, the parallel run method requires a large equipment burden, such as the need to prepare two sets of test systems in the site and in the factory. In addition, there is a large human burden, such as deploying testers on site for a long period of time. It is good if the budget, personnel, etc. at the time of new system development or batch replacement are sufficient, but it is difficult to secure the budget, personnel, period, etc. of the user because the scale is small at the time of partial replacement of the system. Therefore, in the partial replacement, the parallel run test cannot be performed as in the case of the batch replacement in most cases.

With respect to such partial replacement, the test method disclosed in Patent Document 1 can be applied as a test method for realizing the above two items. According to this test method, it is possible to accumulate communication data from field devices acquired by a local operation system and bring the data into the factory for testing. By applying this test method, the accuracy of the test can be improved. In addition, this test method has an advantage that conditions that cannot be created by a simulator in the factory or that are difficult to create can be collected and used from the field in the form of communication data.
For example, depending on the local operation system, the signal output in the order of A and B from the site side may arrive at the local operation system side in the order of B and A due to the configuration specific to the local device depending on the configuration of the field device. . Since these are events that are not noticed in the factory test, problems will be identified after the replacement equipment is installed on site. Therefore, there is a problem that a reworking work for solving those problems occurs and an extra work man-hour is generated. From this point of view, using the data acquired by the local operation system according to the conventional technology as test data is a very effective test method because it can accurately and efficiently test the state that can occur in the field. .

In conducting tests in the factory, display information from the on-site equipment and control information output by the operation management system are important factors when simulating the operation status of the operation management system during operation in the field. FIG. 1 shows a conceptual diagram of a train operation management system. FIG. 1A shows the system configuration, and FIG. 1B shows the information flow. The operation management system 1 collects information from the signal equipment 3 and the like installed at the site, detects the train status, and controls the operation of the train based on the train schedule. When the train is controlled, first, the control information 11 is output from the operation management system 1 to the train centralized control device 2. The train centralized control device 2 that has received the control information 11 outputs the control information 12 to the signal equipment 3 and transmits a control answer 13 to the operation management system 1.
When the signal equipment 3 receives the control information 12, it controls and operates the traffic lights at the site, and after the traffic lights change, the signal equipment 3 transmits the state from the signal equipment 3 to the train centralized control device 2 as display information 14. When receiving the display information 14, the train central control device 2 transmits the display information 14 to the operation management system 1 as display information 15. The operation management system 1 displays the information on the display device 4 provided on the command console as traffic signal display information based on the transmitted display information. The commander monitors the information displayed on the display device 4 or the like, and performs operations such as control commands if necessary.

On the other hand, in the test method of the above-mentioned patent document 1, since communication information collected from the field equipment is only display information, it is not sufficient as a test in a factory. The information collected from the field equipment can be used 100% in a simple display information confirmation test in which the display information output from the field equipment is confirmed by a display device, but cannot be used as it is in the control information output confirmation test.
When the control information is output, the control output is performed from the train centralized control device 2 (hereinafter referred to as a control device), the output control information reaches the signal equipment 3 at the site, the signal equipment 3 operates, and the state is displayed information. As a sequence reflected from the signal equipment 3 to the operation management system 1 via the control device 2. That is, it cannot be said that it is a strict test unless it operates in the test system in the order of the control information from the control device and the display information from the field device. However, since the field collection data is only display information, if the data is used in a test, the display information is answered even if there is no control information output from the control device, and the correct sequence cannot be maintained.

  Therefore, in order to conduct a control information output test in the factory, it is necessary to perform a test to ensure a sequence by manually outputting one display information from the field collection data after one control information is output from the control device. It is. However, if the data frequency is high, the manual operation for each step is complicated, and above all, using the collected display information received several tens of cases per second, the local control information and the timing of the display information It is virtually impossible to conduct a confirmation test.

  As described above, the test method of Patent Document 1 has a problem that it is insufficient to perform a test for ensuring equivalence with a local operation system. In addition, with the conventional technology, there is no mechanism that can automatically and seamlessly perform the order of control information and display information at the same timing as the local operation system. There was only a typical test method.

The present invention has been made in view of the above points, and in order to reduce the number of man-hours and the period required for the field adjustment test using the train operation management system in the field, the environment equivalent to the field or more in the factory test. The purpose is to realize an environment where the test can be performed.
Also, in the factory test system, the environment and operation of the local operation system are simulated, and the communication data acquired by the local operation system is used for the control information output confirmation test and the display information confirmation test, thereby improving the accuracy of the system test. The purpose is to improve.

  The present invention is equivalent to a train operation management system in order to connect to an operating train operation management system and store a communication data input to the train operation management system and to test the train operation management system. A test system with a comfortable environment. Then, when the gateway device is connected to the test system and the communication data accumulated by the gateway device is input as test data and the test is performed, the monitor run mask processing unit is provided for controlling whether or not the test data can be received. is there.

  In addition, the present invention provides a train operation management system that is in operation, a test system that has an environment equivalent to the train operation management system, and a train operation management system that is in operation in order to perform a test of the train operation management system. And a gateway device for connecting the test system. Then, the gateway device transfers communication data input to the operating train operation management system to the test system as test data. The test system includes a monitor run mask processing unit that controls whether or not the test data can be received when the communication data transferred from the gateway device is input as test data and the test is performed.

  The monitor run mask processing unit provided in the test system includes mask pattern information for setting whether or not test data can be received. When control information is output from the test system, the monitor run mask processing unit outputs the control information from the control target equipment. The mask pattern information is unmasked so that the display information can be received as test data.

According to the present invention, when communication data acquired from an on-site system by a gateway device is input to a test system, communication data corresponding to the control information can be input after the control information is output by the test system. . For this reason, test data can be input in the same sequence as during actual control during a test in the test system, thereby improving test accuracy.
As a result, it is possible to carry out highly accurate tests and various tests in the factory test, so the time required for the field adjustment test using the system in operation after the installation in the field can be reduced. Work man-hours can be reduced.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
First, the outline | summary of the operation management system which is a test object of the test apparatus by this invention is demonstrated.

  FIG. 1 shows a conceptual diagram of a train operation management system. As shown in FIG. 1 (a), the train operation management system includes an operation management system 1 that controls the operation of the train, and a train centralized control device that relays control information from the operation management system 1 and controls on-site equipment. (CTC: Centralized Traffic Control) 2 and signal equipment 3 are provided. In addition to the signal equipment, the field equipment controlled from the operation management system 1 includes a switch (point), but here, the field equipment is described as a representative signal equipment.

Next, an outline of the operation of the train operation management system will be described based on the sequence diagram showing the flow of information of the train operation management system shown in FIG. The operation management system 1 collects information from the signal equipment 3 and the like installed at the site, detects the train status, and controls the operation of the train based on the train schedule. When the train is controlled, first, the control information 11 is output from the operation management system 1 to the train centralized control device 2. The train centralized control device 2 that has received the control information 11 outputs the control information 12 to the signal equipment 3 and transmits a control answer 13 to the operation management system 1.
When the signal equipment 3 receives the control information 12, it controls and operates the traffic lights at the site, and after the traffic lights change, the signal equipment 3 transmits the state from the signal equipment 3 to the train centralized control device 2 as display information 14. When receiving the display information 14, the train central control device 2 transmits the display information 14 to the operation management system 1 as display information 15. The operation management system 1 displays the information on the display device 4 provided on the command console as traffic signal display information based on the transmitted display information. The commander monitors the information displayed on the display device 4 or the like, and performs operations such as control commands if necessary.

In FIG. 2, the example of schematic structure of the process part which performs the operation control of a train in the operation management system 1 used as the premise in describing this Embodiment is shown. With reference to FIG. 2, the outline | summary of the operation management process of the operation management system 1 is demonstrated.
Display information indicating the state of the signal equipment 3 is transmitted to the operation management system 1 via the train central control device 2, and the transmitted information is input to the CTC display information processing unit 21. The CTC display information processing unit 21 detects changes in the display information based on the input display information, and updates data representing the state of signal equipment and the like managed in the operation management system 1. Then, based on the updated data, processing units such as the train tracking unit 22, the column number setting unit 23, the order determination unit 24, and the approach detection unit 25 are sequentially executed. Through these processes, the state of the train to be controlled is grasped, it is determined whether the train can be run, and the on-line status, the approach status, etc. of the train are determined. Then, the control monitoring unit 26 monitors whether the display information for the already output control information has been correctly received. Next, the route control unit 27 outputs control information for the next train. After the output of the control information, the process returns to the CTC display information processing unit 21 and the display information transmitted from the train centralized control device 2 is input to repeat the above processing.
In the operation management system 1, train operations are managed by repeatedly executing the processes from the CTC display information processing unit 21 to the route control unit 27 at a constant cycle.

Next, as an embodiment of the present invention, a test configuration example at the time of a software test of the operation management system will be described on the assumption that it is applied to the operation management system described so far. In this example, a test for confirming the function of the software of the operation management system 1 is performed in order to repair software installed in the operation management system 1 or to replace the operation management system 1.
As an example of a system to which the present invention is applied, as shown in FIG. 3, an example in which a test operation management system is connected to a local operation management system via a gateway device and a test is performed, and as shown in FIG. There are two examples in which a test is performed using data once stored in the gateway device. First, two examples will be described.

  FIG. 3 shows a test configuration example of an operation management system when a test is performed on site as a first example to which the embodiment of the present invention is applied. FIG. 3 (a) shows a test configuration example of the operation management system, and FIG. 3 (b) shows a sequence example showing the flow of information during the test.

  The test configuration example in FIG. 3A includes an operation management system 1, a train central control device 2, a signal facility 3, a gateway device 5, and a test system operation management system 6. The operation management system 1, the train centralized control device 2, and the signal equipment 3 are systems or devices that are actually operating locally, and are referred to as “local operating systems”. The test system operation management system 6 simulates the execution environment including the software of the operation management system 1 in operation, and the software to be tested is replaced with the one after the repair. The test system operation management system 6 is referred to as a “test system”.

  The gateway device 5 is connected to a transmission path connected to the local operation management system 1 and the test operation management system 6, and the local operation management system 1 and the test operation management system are connected via the gateway device 5. 6 is connected. Then, the gateway device 5 transfers the display information transmitted from the train central control device 2 of the “local operation system” to the test system operation management system 6, thereby performing a function confirmation test of the software of the test system operation management system 6. carry out.

  Next, with reference to FIG. 3B, an outline of the information flow during the test will be described. Of the information sequence at the time of the test in FIG. 3B, the sequence on the local operating system side is the same as the information flow described in FIG. The sequence on the test system side represents the flow of information between the test system operation management system 6 and the gateway device 5 that transfers information from the local operation system side.

When the test operation management system 6 is installed in the field and the test is performed, the system time of the operation management system 1 and the operation management system 6 in operation are synchronized, and the same train schedule information is registered and the test is performed. Do. Thereby, the output timing of the control information output from the operation management system 1 in operation and the test operation management system 6 can be matched.
When the control information 11 'is output from the test operation management system 6 almost simultaneously with the output of the control information 11 from the operation management system 1, the gateway device 5 absorbs the information and returns to the local operation system side. Not flowing. Then, when the display information 15 is transmitted from the train centralized control device 2 in operation, the gateway device 5 relays the display information 15 and transfers it to the test system operation management system 6 as display information 15 ′.

  By operating in this way, the test operation management system 6 can input the display information 15 'at almost the same timing as the actual operating system, so that the control timing can be confirmed and the validity of the control output can be confirmed. Can be verified.

Next, a configuration example of the gateway device to which the exemplary embodiment of the present invention is applied will be described.
FIG. 4 shows a configuration example of a gateway device as an embodiment of the present invention. The gateway apparatus has the same function as the data transfer apparatus according to the prior art disclosed in Patent Document 1.

The gateway device 5 transmits the communication data flowing in the network in only one direction, the data buffering unit 52 for storing the acquired communication data, and the acquired communication data to reproduce the communication. A communication reproduction unit 53 is provided. In addition, a communication data storage unit 54 that stores communication data stored by the data buffering unit 52 is provided.
In the gateway device 5, display information transmitted from the train central control device 2 in operation is acquired by the communication data acquisition unit 51, and is transmitted to the test system operation management system 6 via the communication reproduction unit 53. Thereby, display information can be transferred to the test system operation management system 6 in parallel with the local operation system operation management system 1, and a test using actual data can be performed in real time.

  Since the gateway device 5 is set to allow only one-way communication from the local operation system side to the test operation management system 6 side, the control output from the test operation management system 6 is performed. Information is not sent to the running system. For this reason, it becomes possible to carry out a test without affecting the operation management system 1, the train centralized control device 2, and the signal equipment 3 that are operating in the field.

  Further, the gateway device 5 can store the display information acquired by the communication data acquisition unit 51 in the communication data storage unit 54 by the data buffering unit 52. The data stored in the communication data storage unit 54 is read out by the communication reproduction unit 53 and transmitted to the test system operation management system 6, so that the test can be performed at a timing different from the actual operating system. .

FIG. 5 shows a second example to which the embodiment of the present invention is applied, in which test data is collected at the site, and the test operation management system 6 is installed as a test apparatus in the factory to perform the test. An example of test configuration of the operation management system is shown.
In FIG. 5, only the gateway device 5A is connected to the local operation system and installed at the site, and the test system operation management system 6 and the gateway device 5B are connected to the factory as test devices in the factory. An example is shown.

  In the second example shown in FIG. 5, the display information transmitted from the train centralized control device 2 operating in the field is acquired by the data buffering unit 52 of the gateway device 5A connected to the system of the local operation system, The data is accumulated in the communication data accumulation unit 54. Then, the information stored in the communication data storage unit 54 is recorded in a portable storage medium or the like, registered in the gateway device 5B connected to the test system operation management system 6 in the factory, and the test system operation management is performed by the communication reproduction unit 53. The test is performed by sending it to the system 6.

  By configuring in this way, the test operation management system 6 is installed in the field, the repaired software and the device to be replaced are brought into the field, and the actual data is stored in the factory before conducting the test on site. A test using can be performed.

As described above, in the first example, when the functional test of the test system operation management system 6 is performed, the timing of the control output of the test system operation management system 6 is adjusted so as to coincide with the local operation system. However, even if the control operation timing of the test operation management system 6 is operated so as to match that of the local operation system, it cannot be made to match completely. Further, in the second example, even when testing is performed in the test system operation management system 6 in the factory, the test start timing is adjusted so as to match the input timing of the communication data acquired from the site. However, even in this case, the control output and the display information input timing may not follow the sequence.
Therefore, in one embodiment of the present invention, a monitor run mask processing unit is provided in the operation management process of the test system operation management system 6.

  In FIG. 6, the example of schematic structure of the operation management process of the test type operation management system 6 by the example of this Embodiment is shown. In this example, a monitor run mask processing unit 28 is provided between the CTC display information processing unit 21 and the route control unit 27 of the conventional operation management process shown in FIG.

  The monitor run mask processing unit 28 defines a mask in advance so as not to detect display information for a traffic signal to be tested. The mask is released when the control information is output from the test operation management system 6. Thereby, when the control information is not output from the test system operation management system 6, even if the display information as test data is input, the display information is not detected, and the display information is detected after the control information is output. I can do it.

  FIG. 7 is a flowchart showing an example of monitor run mask processing by the monitor run mask processing unit. The monitor run mask processing unit 28 is provided between the CTC display information processing unit 21 and the route control unit 27 in the operation management process, and is repeatedly executed in accordance with the operation management process executed at regular intervals.

  First, when the monitor run mask process is started for the first time, monitor run masks are set for all display bits (step S701). Then, it is detected whether there is a control output from the route control unit 27 (step S702), and it is determined whether there is an output of control information (step S703). If the control information is output as a result of the determination, a pseudo control answer that simulates the reception of the control answer corresponding to the output control information data from the train centralized control device is generated (step S704). Next, it is determined whether the monitor run mask relating to the traffic light corresponding to the output control information is set (step S705). As a result of the determination, if the mask bit state of the monitor run mask is the mask setting state, the mask state of the target traffic light is canceled (step S706). If the control information is not output as a result of the determination in step S703, or if the mask bit state of the monitor run mask is not the mask setting state as a result of the determination in step S705, the process proceeds to the next process.

  Next, the display information input to the test operation management system is received (step S707). And about the display information which changed from the display information received last time among the input display information, the monitor run mask regarding the traffic light corresponding to the said display information is made into a setting state again (step S708). Finally, it is determined whether the test is finished (step S709). If the test is finished, this process is finished. As a result of the determination, if the test is not finished, the process returns to step S702, and the process is repeated in accordance with the execution cycle of the next operation management process.

There are the following two methods for inputting the display information input to the test operation management system in this process. The first is a case where the test is carried out in the above-described first example (example shown in FIG. 3) as a configuration in which the test operation management system 6 is connected to the system operating in the field via the gateway device 5. . In this case, display information transmitted from the field facility is transferred to the test system operation management system in real time via the gateway device 5.
Second, in the second example described above (the example shown in FIG. 5), display information is accumulated in the gateway device 5A connected to the system currently operating in the field, and the accumulated display information is brought back to the factory for testing. This is the case. By registering the display information accumulated in the field to the gateway device 5B connected to the test operation management system 6 installed as a test device in the factory, and outputting the registered display information from the gateway device 5B, the test system Input to the operation management system 6.
In either case, by incorporating monitor run mask processing, the timing of control information output and display information input of the test operation management system can be adjusted, so a highly accurate test can be performed. it can.

  Next, a specific operation example by incorporating a monitor run mask processing unit will be described.

  FIG. 8 shows an operation example when a delay in the output of the control information of the test operation management system occurs in a configuration without the conventional monitor run mask processing unit. Here, the case where the gateway apparatus 5 is connected to the local operation management system 1 and the test system operation management system 6 is connected via the gateway apparatus 5 will be described as an example.

  The left side of FIG. 8 shows a normal sequence by the operation management system 1 of the local operation system. In this case, when the gateway device 5 connected to the operation management system 1 receives the display information 14 from the train central control device 2, it transfers it to the test operation management system 6 and transmits it as display information 15 '. The test operation management system 6 is originally set to output control information at time t1 at the same timing as the operation management system 1, but in reality, the output timing is delayed, and the control information 11 'is output at time t3. Is output. In this case, since the display information 15 ′ transferred via the gateway device 5 is transferred at time t2, the display information is input before the output of the control information, and a correct test cannot be performed.

FIG. 9 shows an outline of the mask setting function when the monitor run mask processing unit is incorporated.
FIG. 9A shows an example in the case where control information that should originally be output at time t1 is not output in the test system operation management system 6. In this case, since the mask is set by the monitor run mask processing unit so that the display information is not detected in advance for the traffic signal to be tested, even if the display information 15 'is input at time t2, Does not detect display information.

  FIG. 9B shows an example when the control information 11 ′ is output at time t 1 in the test system operation management system 6. In this case, the monitor run mask processing unit cancels the mask related to the traffic signal by the output of the control information 11 ′. Thereby, when the display information 15 'received at time t2 is input, the information can be detected.

  FIG. 9C shows an example in the case where the control information is not output at the time t1 and the control information 11 ′ is output at the time t3 in the test system operation management system 6. In this case, the display information 15 'is input at time t2 prior to the output of the control information, but since the mask is set at that time, the display information is not detected. When the control information 11 ′ is output at time t3, the mask is released by the monitor run mask processing unit. Thereby, the display information 15 'can be detected by the processing of the CTC display information processing unit executed in the next cycle. In the figure, the input timing of the display information 15 'is described only once. However, in actuality, when the display information is input by the CTC display information processing unit that is repeatedly executed at a fixed period, All information is entered repeatedly. Therefore, the display information can be acquired in the CTC display information processing unit executed in the cycle after the control information is output.

  FIG. 10 shows an example of creating a monitor run mask. The mask information to be set is created as a traffic light mask pattern file 32 with reference to a traffic light constant 31 which is one of equipment constants held in the operation management system. The mask setting / cancellation state of the monitor run mask is expressed by rewriting the mask state data in the traffic signal mask pattern file 32. The created traffic signal mask pattern file 32 is set so as to be referred to from the CTC display information processing unit of the test operation management system 6, and the mask state of the traffic signal mask pattern file 32 is a set state, that is, when a mask is set. The display information change by the CTC display information processing unit is not detected.

  For example, a case where a monitor run mask is set for all the display bits of the traffic signal mask pattern file 32 at the start of the monitor run mask process will be described. When the mask state is set as shown in FIG. 10, the operation management system 1 of the local operation system controls the traffic signal of “A station 1 RA”, and the display information of 1 RA is transferred to the test operation management system 6 via the gateway device 5. Display information is not received even if it is transferred. As a result, the CTC display information processing unit of the test system operation management system 6 is in a state where no change in display information is detected.

FIG. 11 shows an operation example when the mask is normally released by the output of the control information from the test system operation management system 6.
The traffic management system 1 of the local operation system controls the traffic signal of “A station 1RA”, the traffic signal 3 changes and returns display information, and the test system operation management system 6 “A station” is almost the same timing as the local operation system. A case where 1RA "control information is output will be described.
When the monitor run mask processing unit of the test system operation management system 6 detects the output of the control information, the data of the mask state 321 of “A station 1 RA” in the traffic signal mask pattern file 32 is released. Thereby, it becomes possible to receive the display information of the corresponding traffic light. As a result, when the 1RA display information is transferred to the test operation management system 6 via the gateway device 5, the CTC display information processing unit of the test operation management system 6 detects a change in the display information of 1RA. Can do.

FIG. 12 shows an operation example when the control information is erroneously output to the traffic signal different from the operation management system 1 of the local operation system in the test system operation management system 6.
For example, when the operation management system 1 of the local operation system controls the traffic signal of “A station 2RB” and the test operation management system 6 controls the traffic signal of “A station 1RA”, it is input to the test operation management system 6. The display information is “A station 2RB” display information. On the other hand, in the monitor run mask processing unit of the test system operation management system 6, the data of the mask state 321 of “A station 1 RA” in the traffic signal mask pattern file 32 is released as the control information of “A station 1 RA” is output. To do.
Thereby, even if the display information of “A station 2RB” is transferred to the test system operation management system 6, the signal is not received because it remains in the mask setting state. Further, the display information of “A station 1 RA” for which the control information is output by the test system operation management system 6 is not controlled by the local operation system operation management system 1, and therefore is not input.
As a result, the control monitoring unit of the test system operation management system 6 monitors whether or not display information corresponding to the control information is input. As a result, no display information is input and it is determined that a timeout has occurred. It can be detected that erroneous control information has been output by detecting the timeout of the test system operation management system 6.

As described above, according to the present invention, it is possible to easily perform a function test using actual communication data collected from a system operating in the field. In addition, this test can be performed by installing a test operation management system in the site, and can also be performed in a test environment management system installed as a test device in the factory in the same environment as the site.
Conventionally, the improvement in the quality of the test has been hindered by the timing difference that occurs during the test. However, in the present invention, this timing difference can be eliminated, so that the test quality can be improved. Furthermore, tests such as detection of erroneous control and confirmation of control timing, which have been difficult to perform in the past, can be performed.

Further, by installing the gateway device 5 in the field and operating the data buffering unit, it is possible to accumulate a special state at the site such as only several times a year.
By registering the communication data accumulated in this way in a test apparatus in the factory, it becomes possible to perform a test in a special state at an arbitrary time. Conventionally, such a special condition test can only be carried out in a simulated manner with a simulator. However, according to the present invention, a test that has been difficult in the past can be easily performed. In addition, in such special conditions, it is difficult to reproduce the same state as the local site due to subtle deviations in the control output and display information input timing. Therefore, it is possible to easily perform a reproduction test.

  In addition, data in such a special state can be created using the gateway device 5. The gateway device 5 is equipped with a data processing unit for editing data. By rewriting part of the communication data stored in the gateway device 5, data in a special state is arbitrarily created and tested. You can also In this way, the processing unit that edits data can also be realized by using file editing software that is standardly installed in a computer or the like used in the gateway device.

  As a result, the communication data acquired from the system operating in the field can be accumulated in the gateway device 5 and the information can be processed, so that test data simulating a state that is difficult to occur at the time of abnormality or in the field can be created. . Therefore, not only a normal test but also a rare test such as an abnormality can be performed, and high quality can be ensured.

  Furthermore, by always operating the data buffering unit of the gateway device 5, it is possible to collect information at the time of abnormality occurring in the local operation system. Then, by registering the collected information in a test apparatus in the factory, it is possible to easily realize a reproduction test at the time of abnormality, which has been difficult in the past. As a result, it is possible to obtain a great effect not only for tests for system maintenance and the like, but also for investigating the cause when an abnormality occurs in a local operation system and for repairing problems.

  Furthermore, it is possible to evaluate a plurality of local environments with a test apparatus of a set of test system operation management systems installed in the factory.

  In addition, the data acquired by the gateway device can be applied to handling training for commanders. The test apparatus according to the present invention can be used as an apparatus for training a commander, and information on actual local operation system acquired by a gateway apparatus can be used as training data. As a result, training using special conditions (accidents such as train delays and equipment failures) of the field equipment becomes possible.

  Further, the gateway device can be provided with a processing unit that acquires the output result of the operation management system in operation in the field and the output result of the test operation management system and compares the output results. By comparing the respective output results by the comparison processing unit, it is possible to check the soundness of the test system operation management system including the software for updating the system. The comparison processing unit provided in the gateway apparatus may be provided with a mechanism for outputting an alarm to notify an abnormality when there is a difference in output results or when there is a large difference in output timing. This makes it possible to perform soundness confirmation with higher accuracy and efficiency than the comparison of output results by human systems, such as conventional visual confirmation.
