Description

Technical Field

[0001] The utility model relates to the technical field of communication interfaces between devices, in particular to an interface communication debugging tool and a railway signal power supply screen test system. Background Art

[0002] Railway signal power supply panels and UPS (Uninterruptible Power Supply) are often used together in railway signal systems. For railway signal power supply panel manufacturers, UPS equipment is usually purchased from outside or shipped directly to the construction site, and is therefore not in the railway signal power supply panel production workshop. In addition, different UPS equipment manufacturers and models are different. Therefore, it is almost impossible to build a real debugging environment for each set of railway signal power supply panels before leaving the factory (the UPS equipment cannot be actually in place, that is, it cannot actually reach the railway signal power supply panel production workshop). Therefore, it is difficult to debug the communication interface with the UPS for all railway signal power supply panel products before leaving the factory, which leads to the commissioning process before the equipment is put into use, which is often accompanied by abnormal communication between the railway signal power supply panel and the UPS, increasing the difficulty of debugging on-site equipment.

[0003] Therefore, there is an urgent need to develop a technology that can solve the above technical problems. Utility Model Content

[0007] The first simulator and the second simulator are used to simulate the communication between an uninterruptible power supply UPS and a railway signal power supply panel respectively;

[0008] The first simulator and the second simulator are connected to a communication interface on a railway signal power supply panel that needs to be adjusted;

[0016] Interface communication debugging tooling is connected to the railway signal power supply panel.

[0025] The power supply output terminal of the switching power supply 300 is connected to the power supply input terminal of the first simulator 100 and the power supply input terminal of the second simulator 200, respectively, for providing working power for the first simulator 100 and the second simulator 200;

[0026] The first simulator 100 and the second simulator 200 are respectively used to simulate the communication between an uninterruptible power supply UPS and a railway signal power supply panel;

[0027] The first simulator 100 and the second simulator 200 are connected to a communication interface on a railway signal power supply panel that needs to be adjusted.

[0028] In the present invention, in a specific implementation, the switching power supply 300 is connected to the external AC power grid (AC220V AC power grid) and is used to convert the AC voltage input from the external AC power grid into a direct voltage and then output it to the first simulator 100 and the second simulator 200;

[0029] In a specific implementation, the switching power supply 300 is used to implement an AC 100-240V input and a DC 24V / 5A output, providing a DC 24V power supply for the first simulator 100 and the second simulator 200 .

In addition, there is an Ethernet interface for program downloading, which can also be used as a reserved interface for the Ethernet communication interface.

[0035] In specific implementation, the first simulator 100 and the second simulator 200 need to be copied with mature UPS simulation software (ie, program) in the prior art in advance, so as to run the UPS simulation software (ie, program) during testing.

[0036] It should be noted that UPS simulation software is existing and technologically mature software. Specifically, the "UPS debugging tooling test software" developed by Tianjin Railway Signal Co., Ltd. can be used. The software version is: V1.00. The UPS communication interfaces that currently support simulation are: Kehua FR-UK33_GEL and KR / B1110 UPS, Zhongda HPH and NT UPS, Huawei 5000A UPS, Bayer CHP UPS, Emerson NX, ITA2 and UL33 UPS.

[0037] The UPS simulation software "UPS debugging tooling test software" can display, store and modify the simulated "UPS data" and complete data interaction with the railway signal power panel according to the actual UPS interface protocol. It is worth noting that in addition to simulating the standard MODBUS protocol (such as the Kehua FR-UK33_GEL UPS interface protocol), it can also simulate non-standard free interface protocols (such as the Zhongda HPH UPS interface protocol).

[0038] When the UPS simulation software "UPS debugging tooling test software" is running, the first simulator 100 and the second simulator 200 can respectively imitate the data collection (corresponding to the simulator's data modification), data display, interface parameter (baud rate and communication address) setting and data upload functions performed by a real UPS device.

[0050] It should be noted that in Figure 2 In the example, for both simulators 100 and 200, pin A is the RS485 positive terminal, and pin B is the RS485 negative terminal. When the level on pin A is higher than that on pin B, the transmitted signal is 1, and vice versa. Pin R is the RS232 receiving terminal, used for signal reception, and pin T is the RS232 transmitting terminal, used for signal transmission. Pin GND is the common signal ground pin for both pins R and T.

[0064] It should be noted that the plug-in terminal block JXS includes a plurality of plug-in terminals. Specifically, the plug-in terminal block JXS is a 16-position terminal block including 16 plug-in holes.

[0065] The other end (outer end) of the plug-in terminal block JXS is connected to the railway signal power supply panel (specifically, the RS485 communication interface or RS232 communication interface on the railway signal power supply panel) (i.e., communication connection, for example, can be through an RS485 bus or RS232 bus with a connector);

[0066] Furthermore, the terminal JXS-1 and the terminal JXS-2 on the plug-in terminal block JXS are respectively connected to the COM2-1 pin and the COM2-2 pin of the first RS485 communication interface on the first simulator 100;

[0071] Terminals JXS-13, JXS-14 and JXS-15 on the plug-in terminal block JXS are respectively connected to the COM1-2 pin, COM1-3 pin and COM1-5 pin of the RS232 communication interface on the second simulator 200.

[0072] It should be noted that the tooling of this utility model adopts a box structure with an openable front door. The switch power supply, circuit breaker, and other components are installed in the device box. The first simulator 100 and the second simulator 200 have built-in 12-inch touch screens embedded in the front door for convenient operation and display. The device box is equipped with a handle on the top and plug-in terminals for power and communication on the side, making it portable and easy to connect.

[0073] In this utility model, the railway signal power panel is a mature and widely used device in railway signal systems. The railway signal power panel used by the interface communication debugging tool of this utility model can be, for example, a PK-type railway signal power panel produced by Tianjin Railway Signal Co., Ltd., which serves as the debugging object (i.e., the service object) in this utility model.

[0074] In the present invention, the switching power supply 300 can be any well-known power supply module capable of converting an external 220V AC input voltage into a 24V DC output voltage. Specifically, the switching power supply 300 can be, for example, the CP-E 24 / 5.0 switching power supply manufactured by ABB, which is used to provide power to both the first simulator 100 and the second simulator 200.

[0075] Based on the above, the present invention also provides a railway signal power supply panel test system, which includes the interface communication debugging tooling as described above, and a railway signal power supply panel;

[0076] Interface communication debugging tooling is connected to the railway signal power supply panel.

[0077] In order to more clearly understand the technical solution of the present invention, the debugging process (ie, the simulation test process) of the present invention is described below.

[0078] The first step is to connect the first simulator 100 or the second simulator 200 to the RS485 communication interface or RS232 communication interface on a railway signal power supply panel that needs to be adjusted via the RS485 bus or RS232 bus;

[0079] Then, the first simulator 100, the second simulator 200 and the switching power supply 300 are connected, and the circuit breaker is closed to keep the power on;

[0080] The second step is to open and run the UPS simulation software (i.e., program) installed on the first simulator 100 or the second simulator 200;

[0081] Step 3: The main interface of the UPS simulation software (i.e., program) is displayed on the touch screen of the first simulator 100 or the second simulator 200. The main interface displays all UPS manufacturers (specifically, Kehua, Zhongda, Huawei, Burke, Bernard, Easy, Emerson, Dinghan, etc.). The staff selects a specific UPS manufacturer to be debugged (for example, Kehua) on the main interface.

[0082] In the fourth step, for the selected UPS manufacturer (e.g., Kehua), a UPS model to be debugged is selected from the various UPS models of the manufacturer displayed on the display interface, such as the FR-UK33 GEL (10-60kVA) model, thereby driving the software program corresponding to the model that has been pre-installed in the simulator. This allows the first simulator 100 or the second simulator 200 to simulate the UPS device of this manufacturer and model and communicate with the railway signal power panel;

[0083] Among them, the UPS models included by Kehua manufacturer may include, for example, FR-UK33 GEL (10-60kVA), KR / B3320-J, KR / B1110 and other models.

[0084] It should be noted that for UPS simulation software (i.e. program), after selecting the specific UPS model in the fourth step, the UPS data debugging interface will pop up. In the UPS data debugging interface, the serial port baud rate and communication address can be modified, and the analog data of the UPS can be modified at will. In the further started UPS detailed switch quantity debugging interface, the status of the alarm quantity can be modified at will.

[0085] Step 5: When using the tooling of the present invention for debugging, the analog and switch quantities can be modified on the display interface of the UPS simulation software (i.e., the program) (specifically, the UPS detailed switch quantity debugging interface), and the UPS data and status can be displayed on the display interface;

[0086] At this time, the staff will determine whether the interface communication between the railway signal power supply screen and the UPS is abnormal by checking whether the UPS data and status displayed on the railway signal power supply screen are consistent with the data and status displayed on the display interface of the simulator touch screen on the tooling. If they are consistent, it means that the interface communication between the two is normal. Otherwise, if they are inconsistent, it means that the interface communication between the two is abnormal (i.e., abnormal).

[0087] Compared with the existing technology, the interface communication debugging tooling and railway signal power supply panel testing system provided by the present invention have the following beneficial effects:

[0088] 1. This utility model solves the debugging problem of the communication between the railway signal power panel and the UPS interface;

[0089] 2. The utility model can adopt a compact box structure, which is convenient to carry and use;

[0090] 3. This utility model supports simulation of two hardware interface devices: RS232 and RS485;

[0091] 4. This utility model supports online modification of serial port baud rate and communication address;

[0092] 5. This utility model supports the simulation of communication interfaces of UPS devices of multiple manufacturers and models;

[0093] 6. This utility model can save the cost of transporting UPS equipment to the railway signal power panel manufacturer for debugging;

[0094] 7. This utility model can meet the needs of debugging the interface communication between the railway signal power supply screen and the UPS equipment before leaving the factory, greatly reducing the difficulty of on-site debugging of the railway signal power supply screen products after leaving the factory, improving the work efficiency of the commissioning personnel, and thus saving considerable travel expenses.

[0095] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
