[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] In this application, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0061] Inter-station safety information transmission system: Using computers and modern communication technology, with a safety computer as the core, it exchanges signal information between two or more stations via fiber optic cables through relays and interlocking and automatic block systems, and completes the functions of information collection, transmission and inter-station communication information transmission between stations.

[0063] ZXJ: Positive line relay.

[0064] FXJ: Negative line relay.

[0065] ZDJ: Positive relay.

[0066] FDJ: Negative Relay.

[0067] As can be seen from the background technology, in the existing technology, the number of drive cables in the inter-station security information transmission system is relatively large, which makes it easy to make wiring errors during testing, leading to test failure.

[0068] Therefore, this invention discloses a testing device and method for an inter-station safety information transmission system. In this solution, a one-way testing component and a two-way testing component are respectively connected to the inter-station safety information transmission system via drive and sampling lines. When the status signal generated by the one-way testing component is transmitted to the two-way testing component, it is determined that the signal transmission from one direction to the two directions of the inter-station safety information transmission system is normal. When the status signal generated by the two-way testing component is transmitted to the one-way testing component, it is determined that the signal transmission from the two directions to the one direction of the inter-station safety information transmission system is normal. By using two drive and sampling lines to connect to the inter-station safety information transmission system, the wiring can be simplified, and the test failure can be prevented due to wiring errors.

[0069] like Figure 1 The diagram shown is an architectural diagram of a test device for an inter-station security information transmission system disclosed in an embodiment of the present invention. The test device includes: a one-way test component 1, a two-way test component 2, a first drive sampling line 3, a second drive sampling line 4, and a connecting line 5.

[0070] The one-way test component 1 is connected to the one-way terminal block interface of the inter-station safety information transmission system via the first drive sampling line 3, and the two-way test component 2 is connected to the two-way terminal block interface of the inter-station safety information transmission system via the second drive sampling line 4.

[0071] Among them, the inter-station security information transmission system is the inter-station security information transmission system to be tested.

[0072] It should be noted that the one-way communication port and the two-way communication port of the inter-station security information transmission system are connected to the outside through the one-way terminal block interface and the two-way terminal block interface, respectively. Therefore, the one-way test component 1 and the two-way test component 2 are indirectly connected to the one-way communication port and the two-way communication port by connecting the one-way terminal block interface and the two-way terminal block interface, respectively.

[0073] like Figure 2 The diagram shown is a wiring diagram of an inter-station security information transmission system disclosed in an embodiment of the present invention.

[0074] Connection line 5 connects the one-way communication board and the two-way communication board of the inter-station security information transmission system.

[0075] It should be noted that the one-way communication board and the two-way communication board of the inter-station security information transmission system enable communication between the one-way and two-way communication of the inter-station security information transmission system.

[0076] Specifically, the one-way communication board includes a first communication board and a second communication board located in one direction, wherein the first communication board is... Figure 2 The A-series acquisition section in the middle direction, the second communication board is... Figure 2 The B-series data acquisition section in the middle direction.

[0077] In this context, direction one and direction two correspond to two adjacent stations. For example, direction one corresponds to station A, and the next station after station A is station B, then direction two corresponds to station B.

[0078] The two-way communication board includes a third communication board and a fourth communication board in two directions, wherein the third communication board and Figure 2 The A-series acquisition section in the middle two direction, the fourth communication board, is... Figure 2 The B-series data acquisition section in the middle two direction.

[0079] It is understandable that A-system acquisition in one direction needs to be connected to A-system acquisition in two directions, and B-system acquisition in one direction needs to be connected to B-system acquisition in two directions. Therefore, the first communication board corresponds to the third communication board, and the second communication board corresponds to the fourth communication board.

[0080] In one embodiment, the connecting line 5 includes a first connecting line and a second connecting line made of optical fiber.

[0081] The first connecting line connects the optical module connection ports of the first and third communication boards, and the second connecting line connects the optical module connection ports of the second and fourth communication boards.

[0082] It should also be noted that before starting the test, the two external power supplies should be connected to the first and second directions of the inter-station safety information transmission system respectively, and the circuit breakers in the first and second directions and the power switches of all equipment should be closed to put the inter-station safety information transmission system into operation.

[0083] The one-direction test component 1 is used to generate a one-direction status signal when it receives a one-direction trigger signal input by the user, and send the one-direction status signal to the inter-station safety information transmission system; when it receives the two-direction status signal sent by the two-direction test component, it determines that the signal transmission from the two directions to the one direction in the inter-station safety information transmission system is normal.

[0084] The two-way test component 2 is used to generate a two-way status signal when it receives a two-way trigger signal input by the user, and send the two-way status signal to the inter-station safety information transmission system; when it receives a one-way status signal sent by the one-way test component, it determines that the signal transmission from one direction to the two directions in the inter-station safety information transmission system is normal.

[0085] It should be noted that, under normal conditions, after the communication port of the inter-station safety information transmission system receives the status signal in one direction, it transmits the status signal in one direction to the other direction through the connecting line 5, and outputs it from the communication port of the other direction to the test component 2 in the other direction. Therefore, after the test component 2 in the other direction receives the status signal in one direction, it determines that the signal transmission from one direction to the other direction of the inter-station safety information transmission system is normal.

[0086] Correspondingly, under normal conditions, after the two-way communication port of the inter-station safety information transmission system receives the status signal from the two directions, it transmits the status signal from the two directions to the one direction through the connecting line 5, and outputs it from the communication port of the one direction to the one-way test component 1. Therefore, after the one-way test component 1 receives the status signal from the two directions, it determines that the signal transmission from the two directions to the one direction of the inter-station safety information transmission system is normal.

[0087] In one embodiment, the testing apparatus for the inter-station security information transmission system further includes a CSM testing component, which is connected to the CSM serial interface of the inter-station security information transmission system.

[0088] When the CSM test component obtains a directional status signal and / or a directional status signal from the CSM serial interface, it is determined that the CSM serial interface communication is normal.

[0089] Understandably, the CSM test component acquires various operating parameters of the inter-station security information transmission system in real time through the CSM serial interface. For example, when a user inputs a trigger signal to generate a directional status signal and / or a directional status signal, it will be monitored by the CSM test component. Or, for example, if a connection line of the inter-station security information transmission system is manually disconnected, the parameters of the inter-station security information transmission system will change and be monitored by the CSM test component. The occurrence of the above-mentioned situations all indicate that the CSM serial interface of the inter-station security information transmission system is normal.

[0090] Specifically, the CSM test components include: processor and display device.

[0091] The processor is connected to the display device and is equipped with microcomputer monitoring and testing tools.

[0092] The processor is used to generate corresponding status data based on the status signals in one direction and / or two directions obtained from the CSM serial interface using a microcomputer monitoring and testing tool; and to determine that the CSM serial interface communication is normal when a user input confirmation command is received.

[0093] It should be noted that after the corresponding status data is generated, the status data is displayed through a preset interface and display device.

[0094] The microcomputer monitoring and testing tool will also acquire various operating parameters of the inter-station safety information transmission system and display them through a preset interface and display device. When a connection line in the inter-station safety information transmission system is manually disconnected, the corresponding parameters in the preset interface will change, indicating that the CSM serial interface of the inter-station safety information transmission system is normal.

[0095] Display devices are used to display status data or operating parameters of inter-station security information transmission systems through a preset interface.

[0096] A testing device for an inter-station safety information transmission system disclosed in the above embodiments of the present invention includes: a one-way testing component, a two-way testing component, a first drive acquisition line, a second drive acquisition line, and a connecting line. The one-way testing component is connected to the one-way terminal block interface of the inter-station safety information transmission system via the first drive acquisition line. The two-way testing component is connected to the two-way terminal block interface of the inter-station safety information transmission system via the second drive acquisition line. The connecting line connects the one-way communication board and the two-way communication board of the inter-station safety information transmission system. In this solution, the one-way testing component and the two-way testing component are respectively connected to the inter-station safety information transmission system via drive acquisition lines. When the status signal generated by the one-way testing component is transmitted to the two-way testing component, it is determined that the signal transmission from one direction to the two directions of the inter-station safety information transmission system is normal. When the status signal generated by the two-way testing component is transmitted to the one-way testing component, it is determined that the signal transmission from the two directions to the one direction of the inter-station safety information transmission system is normal. By using two drive acquisition lines to connect to the inter-station safety information transmission system, the wiring is simplified, and wiring errors are prevented from causing test failures.

[0097] A testing device for an inter-station security information transmission system disclosed in the above embodiments of the present invention, such as...

[0101] The two-way button 21 is connected to the input terminal of the two-way relay, and the output terminal of the two-way relay 22 is connected to the inter-station safety information transmission system through the second drive line 4.

[0102] The first-direction relay 12 is used to receive the trigger signal input by the user using the first-direction button 11, enter the reliable energizing state, generate the first-direction status signal, and send the first-direction status signal to the inter-station safety information transmission system; when it receives the status signal sent by the second-direction relay 22, it enters the reliable energizing state to confirm that the signal transmission from the second direction to the first direction in the inter-station safety information transmission system is normal.

[0103] The two-way relay 21 is used to receive the trigger signal input by the user using the two-way button 21, enter the reliable energizing state, generate the two-way status signal, and send the two-way status signal to the inter-station safety information transmission system; when it receives the status signal sent by the one-way relay 12, it enters the reliable energizing state to confirm that the signal transmission from one direction to the two directions in the inter-station safety information transmission system is normal.

[0104] based on Figure 3 The device shown is a test apparatus for an inter-station secure information transmission system, such as Figure 4 The diagram shown is an architectural diagram of a test device for another inter-station security information transmission system disclosed in an embodiment of the present invention.

[0105] The directional relay 12 includes: a directional positive relay 121, a directional positive line relay 122, a directional negative relay 123, and a directional positive line relay 124.

[0106] One-way positive relay 121, one-way positive line relay 122, one-way negative relay 123 and one-way positive line relay 124 are connected to the one-way terminal block interface of the inter-station safety information transmission system through the first drive line 3.

[0107] Specifically, the common terminal of the positive line relay 121, positive line relay 122, negative line relay 123 and positive line relay 124 is connected to the terminal block interface of the inter-station safety information transmission system through the first drive line 3.

[0108] The directional button 11 includes: a first button 111 connected to the input terminal of the directional positive relay 121, and a third button 112 connected to the input terminal of the directional positive relay 123.

[0109] Correspondingly, the two-way relay 22 includes: a two-way positive relay 221, a two-way positive line relay 222, a two-way negative relay 223, and a two-way negative line relay 224.

[0110] The two-way positive line relay 221, the two-way positive line relay 222, the two-way negative line relay 223, and the two-way negative line relay 224 are connected to the two-way terminal block interface of the inter-station safety information transmission system through the second drive line 4.

[0111] Specifically, the common terminal of the two-way positive line relay 221, the two-way positive line relay 222, the two-way negative line relay 223, and the two-way negative line relay 224 is connected to the two-way terminal block interface of the inter-station safety information transmission system through the second drive line 4.

[0113] It should be noted that a positive relay reliably activates by generating a positive polarity status signal. The positive line relay is responsible for responding to the positive polarity status signal to reliably activate, and does not respond to the negative polarity status signal. Similarly, a negative relay reliably activates by generating a negative polarity status signal. The negative line relay is responsible for responding to the negative polarity status signal to reliably activate, and does not respond to the negative polarity status signal.

[0114] A positive energizing relay 121 is used to receive a trigger signal input by the user through the first button 111, enter a reliable energizing state, generate a first status signal, and send the first status signal to the inter-station safety information transmission system.

[0115] The first state signal indicates that the positive energizer relay 121 has entered a reliable energizing state.

[0118] The second state signal indicates that the two-way positive relay 221 has entered a reliable energizing state.

[0119] The two-way positive line relay 222 is used to respond to the first state signal generated by the one-way positive relay 121, enter the reliable energizing state, and confirm that the positive polarity signal transmission from one direction to the two directions in the inter-station safety information transmission system is normal.

[0120] A one-way negative relay 123 is used to receive the trigger signal input by the user through the third button 112, enter the reliable energizing state, generate a third state signal, and send the third state signal to the inter-station safety information transmission system.

[0121] The one-way negative line relay 124 is used to respond to the fourth state signal generated by the two-way negative line relay 223, enter the reliable energizing state, and confirm that the negative polarity signal transmission from the two directions to the one direction in the inter-station safety information transmission system is normal.

[0122] The two-way negative relay 223 is used to receive the trigger signal input by the user through the fourth button 212, enter the reliable energizing state, generate the fourth state signal, and send the fourth state signal to the inter-station safety information transmission system.

[0123] The two-way negative line relay 224 is used to respond to the third state signal generated by the one-way negative line relay 123, enter the reliable energizing state, and confirm that the negative polarity signal transmission from one direction to the two directions in the inter-station safety information transmission system is normal.

[0124] It should be noted that the user can trigger the input signal by pressing the first button 111, the second button 211, the third button 112 and the fourth button 212.

[0125] In practical applications, after pressing the first button 111, the second button 211, the third button 112, and the fourth button 212 respectively, the user should observe whether the two-way positive line relay 222, the one-way positive line relay 122, the two-way negative line relay 224, and the one-way negative line relay 124 are all reliably activated. If so, it is confirmed that the signal transmission of the inter-station safety information transmission system is normal.

[0126] In practical applications, when a status signal in one direction or two directions is transmitted to the inter-station safety information transmission system, the status represented by the indicator lights on the board of the inter-station safety information transmission system is obtained. Based on the status of the indicator lights, it is determined whether the inter-station safety information transmission system has received a status signal in one direction or two directions.

[0127] like Figure 5 The diagram shown is an architectural diagram of a test device for another type of inter-station secure information transmission system disclosed in an embodiment of the present invention.

[0128] Figure 5 The test device for the inter-station security information transmission system shown is based on any of the above-mentioned test devices for inter-station security information transmission systems, with the addition of a server rack.

[0129] The cabinet is used to store one-way test components and two-way test components.

[0130] For example, Figure 5 The cabinet shown has CSM testing components on the top layer, and the remaining layers are one-way testing components and two-way testing components.

[0131] Among them, the positive-current relay 121, the negative-current relay 123, the positive-current relay 221 and the negative-current relay 223 are connected to the corresponding buttons and hidden in the cabinet.

[0132] It is understandable that the purpose of the one-way positive relay 121, the one-way negative relay 123, the two-way positive relay 221, and the two-way negative relay 223 in this application is to receive trigger signals and generate status signals. They do not require user observation and are therefore hidden in the cabinet for protection.

[0133] The positive line relay 122, the negative line relay 124, the positive line relay 222, and the negative line relay 224 are all installed in an open cabinet because it is necessary to observe whether they can be reliably picked up.

[0134] A testing device for an inter-station safety information transmission system disclosed in the above embodiments of the present invention includes: a one-way testing component, a two-way testing component, a first drive acquisition line, a second drive acquisition line, and a connecting line. The one-way testing component is connected to the one-way terminal block interface of the inter-station safety information transmission system via the first drive acquisition line. The two-way testing component is connected to the two-way terminal block interface of the inter-station safety information transmission system via the second drive acquisition line. The connecting line connects the one-way communication board and the two-way communication board of the inter-station safety information transmission system. In this solution, the one-way testing component and the two-way testing component are respectively connected to the inter-station safety information transmission system via drive acquisition lines. When the status signal generated by the one-way testing component is transmitted to the two-way testing component, it is determined that the signal transmission from one direction to the two directions of the inter-station safety information transmission system is normal. When the status signal generated by the two-way testing component is transmitted to the one-way testing component, it is determined that the signal transmission from the two directions to the one direction of the inter-station safety information transmission system is normal. By using two drive acquisition lines to connect to the inter-station safety information transmission system, the wiring is simplified, and wiring errors are prevented from causing test failures.

[0135] Based on the test apparatus for an inter-station security information transmission system disclosed in the above embodiments of the present invention, such as Figure 6 The diagram shows a flowchart of a testing method for an inter-station secure information transmission system disclosed in an embodiment of the present invention. This method is applied to the testing apparatus of any of the aforementioned inter-station secure information transmission systems and mainly includes the following steps:

[0136] S601. When a trigger signal in one direction is received from the user, the one-direction test component generates a status signal in one direction and sends the status signal in one direction to the inter-station safety information transmission system.

[0137] In S106, when the inter-station safety information transmission system receives a status signal from one direction, it will transmit it to the other direction. If there is a problem with the communication between the two directions of the inter-station safety information transmission system, the status signal from one direction cannot be transmitted to the other direction.

[0138] S602. When a user inputs a two-way trigger signal, the two-way test component generates a two-way status signal and sends the two-way status signal to the inter-station safety information transmission system.

[0139] In S602, when the inter-station safety information transmission system receives status signals from the second direction, it will transmit them to the first direction. If there is a problem with the communication between the second and first directions of the inter-station safety information transmission system, the status signals from the second direction cannot be transmitted to the first direction.

[0140] It should be noted that the execution order of S601 and S602 is not limited, and S602 can be executed first and then S602. Similarly, the execution order of S603 and S604 is not limited.

[0141] S603. In response to the two-way test component receiving the status signal of one direction sent by the one-way test component, it is determined that the signal transmission from one direction to the two directions of the inter-station safety information transmission system is normal.

[0142] In S603, the two-way test component cannot receive the status signal sent by the one-way test component, indicating that there is a problem with the communication between the one-way and two-way directions in the inter-station safety information transmission system, and the inter-station safety information transmission system cannot transmit the status signal from the one-way direction to the two-way direction.

[0143] S604. In response to the one-way test component receiving the two-way status signal sent by the two-way test component, it is determined that the signal transmission from the two-way to the one-way direction of the inter-station safety information transmission system is normal.

[0144] In S604, the first-direction test component cannot receive the second-direction status signal sent by the second-direction test component, indicating that there is a problem with the communication between the second and first directions in the inter-station safety information transmission system, and the inter-station safety information transmission system cannot transmit the second-direction status signal from the second direction to the first direction.

[0145] Based on the above-described embodiment of the present invention, a testing method for an inter-station security information transmission system is provided. When a trigger signal in one direction is received from a user, a one-direction testing component generates a status signal in that direction and sends the status signal to the inter-station security information transmission system. When a trigger signal in two directions is received from a user, a two-direction testing component generates a status signal in two directions and sends the status signal to the inter-station security information transmission system. In response to the two-direction testing component receiving the status signal in one direction sent by the one-direction testing component, it is determined that the signal transmission from one direction to the two directions in the inter-station security information transmission system is normal. In response to the one-direction testing component receiving the status signal in two directions sent by the two-direction testing component, it is determined that the signal transmission from the two directions to the one direction in the inter-station security information transmission system is normal. In this scheme, the one-way test component and the two-way test component are respectively connected to the inter-station safety information transmission system via drive and sampling lines. When the status signal generated by the one-way test component is transmitted to the two-way test component, it is confirmed that the signal transmission from one direction to the two directions in the inter-station safety information transmission system is normal. When the status signal generated by the two-way test component is transmitted to the one-way test component, it is confirmed that the signal transmission from the two directions to the one direction in the inter-station safety information transmission system is normal. By using two drive and sampling lines to connect to the inter-station safety information transmission system, the wiring can be simplified and the test failure can be prevented due to wiring errors.
