Obviously, the technical solutions described in conjunction with the drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative work, other embodiments and their drawings can be obtained based on the embodiments shown in these drawings.

[0026] Figure 1 is a schematic diagram of an internal wiring verification system for a combination rack according to an embodiment of the present invention. Detailed implementation manners

[0027] The following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments described in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope protected by the present invention.

[0028] An embodiment of the present invention provides an internal wiring verification system for a combination rack, which can efficiently and accurately complete the verification of the internal wiring of the combination rack.

[0029] According to an embodiment of the present invention, there is provided an internal wiring verification system for a combination rack for rail transit, including:

[0030] An operation host, which includes: a display unit, a main control unit, a storage unit, and a data transmission unit;

[0031] A control converter, which includes: a power conversion unit connected to a power supply; a communication conversion unit connected to the data transmission unit;

[0032] A plurality of detection devices for detecting the conduction relationship of the internal wiring, which are connected to each other through device cables and are connected to the communication conversion unit and the power conversion unit through the detection device at the end; the detection devices include type I detection devices and type II detection devices;

[0033] Among them, the type I detection device includes: a first main control board, two first drive and acquisition boards connected to the first main control board through a flat cable, and a first plug-in board connected to the first drive and acquisition board. The first main control board includes a 4-core push-pull self-locking aviation socket on the front of the type I detection device. The first plug-in board includes an interface on the back of the type I detection device for adapting to the combination rack device; wherein the two first drive and acquisition boards are arranged in parallel and are installed perpendicular to the first main control board and the first plug-in board between the first main control board and the first plug-in board;

[0034] Among them, the Type II detection device includes: a second main control board, two second drive and acquisition boards connected to the second main control board through a ribbon cable, and a plug-in circuit board connected to the second drive and acquisition boards. The second main control board includes a 4-core push-pull self-locking aviation socket located on the top surface of the Type II detection device. The plug-in circuit board includes an interface located on the side surface of the Type II detection device for adapting to the combined rack device; among them, the two second drive and acquisition boards are installed parallel to the second main control board and are located below the second main control board.

[0035] In this way, multiple detection devices are respectively and conveniently connected to the internal devices of the combined rack that need to perform wiring verification (that is, check the conduction relationship of the internal wiring of the combined rack) through a plug-in method. Each detection device is connected to each other through device cables and can be connected to a communication conversion unit to realize the necessary communication method conversion from the operation host to the detection device. After all the detection devices are connected, the detection of the conduction relationship of the internal wiring of the combined rack can be started under the control of the operation host, and it can be checked based on the standard / preset conduction relationship in the detection script corresponding to the railway signal relay combination type, so as to judge whether the conduction relationship of the internal wiring of the combined rack is normal or meets the requirements.

[0036] The multiple detection devices include Type I detection devices and Type II detection devices. The Type I detection device is used to detect the conduction state of the wiring of the bottom combined rack device, for example, while the Type II detection device is used to detect the conduction state of the wiring of the side combined rack device, for example. Therefore, the Type I detection device can connect various required monitoring and indicating devices, such as a screen, a power switch, a aviation plug device / structure, an indicator light, etc., through the 4-core push-pull self-locking aviation socket on the front of the first main control board, and on the back (or bottom surface), it can be connected to the corresponding combined rack device at the bottom through the interface of the first plug-in board for adapting to the combined rack device. The three-dimensional layout of the first main control board, two drive and acquisition boards, and the first plug-in board can not only reliably connect to the combined rack device at the bottom through the interface of the first plug-in board for detection, but also provide a good monitoring view through connecting the required monitoring and indicating devices on the front (top surface) of the first main control board. The Type II detection device can connect various required monitoring and indicating devices, such as a screen, a power switch, a aviation plug device / structure, an indicator light, etc., through the 4-core push-pull self-locking aviation socket on the top surface of the second main control board. However, different from the Type I detection device, the plug-in circuit board is connected to the corresponding combined rack device on the side through the interface for adapting to the combined rack device on the side for detection. In addition, the two drive and acquisition boards are arranged parallel to the second main control board to adapt to the application environment in the combined rack. The stacked layout of the second main control board and the two drive and acquisition boards can not only reliably connect to the combined rack device on the side through the interface of the plug-in circuit board for detection, but also provide a good monitoring view through connecting the required monitoring and indicating devices on the top surface of the second main control board.

[0037] It can be seen that through the wiring checking system inside the combination rack provided by the embodiments of the present utility model, the wiring inside the combination rack can be efficiently and accurately checked, especially for automatic checking.

[0038] In this way, the wiring checking system inside the combination rack can assist on-site personnel to more efficiently and accurately complete the wiring checking inside the combination rack, and can be applied to various relay combination types. After the system is built, the continuity test of the wiring inside the combination rack can be automatically completed according to the test script, and the checking process can be configured and highly automated. Among them, the detection equipment and connection cables (or equipment cables) can both adopt pluggable structures, which are convenient for installation and disassembly. The detection equipment does not need to be directly connected to the control converter, but can adopt a serial connection (such as a series connection) structure, reducing the number of sockets and the volume of the device of the control converter. When inserting and removing the detection equipment, the checking personnel can conveniently insert the connection cable, reducing the workload of the checking personnel.

[0075] Preferably, in any embodiment, the detection device and the control converter are connected to each other through a connection cable in pairs.

[0076] Preferably, in any embodiment, the data transmission unit and the control converter are connected through Wireless Fidelity (WiFi) or a Category 5e Ethernet cable.

[0077] Preferably, in any embodiment, the detection device includes: a detection status display screen, an indicator light, and a switch.

[0078] Through the combined rack internal wiring verification system provided by the embodiments of the present utility model, the verification of the internal wiring of the combined rack can be efficiently and accurately completed.

[0079] The operation host is the data processing center and the detection control center of the entire system, and mainly includes: a display unit for displaying the detection process and implementing interface operations, a main control unit for implementing detection logic and result comparison operations, a storage unit for storing detection scripts and detection results, and a data transmission unit for implementing communication with the control converter.

[0080] The control converter is in a box structure, and is externally provided with a 4-core push-pull self-locking aviation socket (alternatively, any 4-hole socket adaptable to the plug of the connection cable), a network port, a WiFi antenna, and a 220V round power supply port, and internally provided with a power conversion unit and a communication conversion unit. The power conversion unit is used for the conversion of AC220V to DC24V to supply power to the detection device. The communication conversion unit realizes the communication conversion of WiFi or Ethernet cable to RS485, and is used for the conversion of the communication mode from the operation host to the detection device.

[0081] The detection device is in the form of a box. On the front of each detection device, there are two 4-core push-pull self-locking aviation sockets (for example, a detection status display screen, indicator lights, and switches can also be set). On the back is the socket interface for adapting to the corresponding device of the combination rack. According to the different types of socket interfaces, the detection devices are divided into Type I and Type II. Among them, the socket interface of the Type I detection device has 28 copper pin feet arranged in 2 columns and 14 rows. Its shape is similar to the JWXC-1700 railway signal relay and can be flexibly inserted and removed from the relay base of the combination rack. The socket interface of the Type II detection device has 54 9-mm copper clips arranged in 3 columns and 18 rows and can be flexibly inserted and removed from the 3×18 side terminal block of the combination rack. In actual use, the number of detection devices supporting different combination types is different. For example, for the combination inside the ordinary-speed station, a set of systems requires at most 10 Type I detection devices and 2 Type II detection devices; for the combination in the ordinary-speed section, a set of systems requires at most 22 Type I detection devices and 4 Type II detection devices.

[0082] The device cable or connection cable used to connect the detection device or the control converter can adopt an AVVR 4-core control cable, of which 2 cores are used for RS485 serial bus communication and 2 cores are used for power supply to the detection device. The two ends of the device cable or connection cable are welded with 4-core push-pull self-locking aviation plugs, which can be flexibly and reliably inserted and removed from the 4-core push-pull self-locking aviation sockets of the above control converter and detection device.

[0083] Each detection device and the control converter are connected to each other through device cables and / or connection cables (for example, special cables can be used), so as to realize the 24V DC power supply of the control converter to the detection device and the serial communication of the control converter to the detection device. The Modbus RTU protocol can be used for communication between the detection device and the control converter.

[0084] The data transmission unit of the operation host can be connected to the network port of the control converter through a Cat5e network cable or to the WiFi antenna of the control converter and adopts Socket communication.

[0085] The internal wiring checking system of the combination rack proposed by the present utility model can be mainly applied, for example, before the combination is processed and shipped out and before the side wiring of the combination rack is not yet carried out after the installation of the combination rack at the construction site.

[0086] Before using this system to detect the internal wiring of the combination rack, it is necessary to first set up the system according to the combination type, insert the required Type I detection devices into the relay base of the combination rack and the Type II detection devices into the 3×18 side terminal block of the combination rack in sequence, and connect them pairwise in sequence with device cables; connect the control converter and the operation host with a network cable; connect the control converter and any one end detection device with a connection cable.

[0087] After the device to be detected is connected and powered on, the detection device can check the conduction relationship of the internal wiring of the combination rack under the control of the operation host. During the checking process, the operation host first selects the type of railway signal relay combination to be checked this time, so as to call the corresponding checking script; then, the operation host issues detection instructions to all detection devices according to the checking script. The basic principle is: let a pin of a type-I detection device output a voltage signal. If the copper pin of any type-I detection device or the clip probe of a type-II detection device detects this voltage signal, this conduction relationship will be fed back to the operation host for summarization. Then, the operation host will compare this detection result with the conduction relationship in the detection script to determine whether they are consistent or abnormal, so as to realize the checking of the conduction relationship of the internal wiring of the combination rack.

[0088] Figure 1 It is a schematic diagram of the internal wiring checking system of the combination rack according to an embodiment of the present invention.
