Description

Technical Field

[0001] This utility model relates to the field of railway signaling equipment technology, and in particular to a separate device for inspecting and controlling relay circuits in interface cabinets. This utility model is applicable to simulated testing scenarios involving the wireless remote control of relay circuits in interface cabinets and combination cabinets during railway signaling construction, as well as the separate module design of related equipment. Through the separate structure design of the drive and acquisition components, the device's adaptability and ease of maintenance are improved. Background Technology

[0002] Currently, in railway signaling construction, the inspection and control of relay circuits in interface cabinets mostly employ integrated drive and acquisition equipment, relying on wired connections or push-button methods for control and data acquisition. This type of equipment integrates the control module, interface module, and mounting structure into a single unit. This integrated design means that if one module fails, the entire unit must be disassembled for repair, making reconnection inconvenient.

[0003] The shortcomings of existing technology: (1) The integrated structural design results in poor equipment installation flexibility and inconvenient handling; (2) There are many cables to be soldered, which makes maintenance inconvenient. When the wiring is not in good contact, the whole thing needs to be disassembled, which increases the repair time and difficulty. (3) The internal short-span wiring inspection relies on manual inspection one by one, which is inefficient and prone to errors, affecting the construction progress.

[0004] The aforementioned defects make it difficult for the flexibility, reliability, and efficiency of interface cabinet relay circuit inspection work to meet the high precision and timeliness requirements of railway signal construction. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing interface cabinet relay circuit inspection devices, such as the inconvenience of installation and use due to their integrated structure and low efficiency in wiring inspection. This invention provides a separate device for inspecting the relay circuit of an interface cabinet. By separating the functional modules, this invention achieves flexible installation, convenient maintenance, stable connection, and efficient inspection of the wiring of the relay circuit from the interface cabinet to the combined cabinet.

[0006] This utility model is achieved through the following technical solution: A separate device for inspecting relay circuits in an interface cabinet includes a remote controller, a remote control relay module, a power supply module, and an inspection and display module. The power supply module is connected to the power supply terminal of the remote control relay module, and the remote controller is wirelessly connected to the input terminal of the remote control relay module. Relay circuit drive terminals and relay circuit acquisition terminals are provided on the outer surface of the interface cabinet. The remote control relay module is connected to the relay circuit drive terminals via an aviation plug cable, and the inspection and display module is plugged into the relay circuit acquisition terminals.

[0007] The remote-controlled relay module includes a housing, within which a microcontroller unit, a wireless communication module, and a relay drive circuit are installed. The microcontroller unit is a 32-bit remote-controlled module, and the relay drive circuit is a 32-bit wireless switching module. The remote controller is wirelessly connected to the microcontroller unit via the wireless communication module. The output terminal of the microcontroller unit is connected to the input terminal of the relay drive circuit. The housing is equipped with a 32-bit indicator LED, a 32-bit aviation socket female connector, and a power input terminal. The power module is connected to the power input terminal, which is connected to the microcontroller unit. The 32-bit indicator LED is connected to the output terminal of the microcontroller unit, and the 32-bit aviation socket female connector is connected to the output terminal of the relay drive circuit. The 32-bit aviation socket female connector is connected to the relay circuit drive terminal via an aviation plug cable.

[0008] A magnet is embedded on the back of the housing of the remote control drive control relay module, and the remote control drive control relay module is attached to the surface of the interface cabinet by the magnet.

[0009] A power switch is provided on the surface of the housing of the remote control drive control relay module.

[0010] The acquisition and inspection display module includes a housing, on which are provided a 32-bit aviation connector, a 32-bit status light, and a negative terminal. The positive terminals of the 32-bit aviation connector and the 32-bit status light are connected to each other, and the negative terminals of the 32-bit status light are connected in series with the negative terminal. The negative terminal is connected to the negative DC24V of the computer. The acquisition and inspection display module is plugged into the acquisition terminal of the relay circuit through the 32-bit aviation connector.

[0011] The relay drive circuit has overcurrent protection of 10A and overvoltage protection of 275V.

[0012] This utility model achieves a closed-loop test of remote driving, status acquisition, and fault detection for the interface cabinet relays through modular design. In actual use, the interface cabinet is connected to a combination cabinet and a computer interlocking cabinet at both ends, and the relay circuit is installed in the combination cabinet. The specific working process of this utility model is as follows: Remote control driving stage: The remote control sends commands to the microcontroller unit (MCU) via a wireless communication module (such as Wi-Fi / LoRa). After parsing the commands, the MCU controls the 32-bit wireless switch module (relay drive circuit) to output drive signals.

[0013] The drive signal travels through the 32-position aviation socket female connector → aviation plug cable → relay circuit drive terminal, driving the relay coils in the combination cabinet one by one.

[0014] The 32-bit LED on the casing displays the driving status (on / off) in real time, making it easy to confirm on-site.

[0015] Status acquisition phase: After the relay contacts inside the cabinet are activated, their status (closed / open) is fed back to the acquisition and display module through the relay acquisition terminal.

[0016] The data acquisition and display module reads the status of 32 contacts in parallel through a 32-bit aviation connector, and displays the status visually through 32-bit status lights. The negative terminal is connected to the negative terminal of the DC24V system to form a circuit.

[0017] Security protection mechanism The relay drive circuit has overcurrent protection (10A) and overvoltage protection (275V) to prevent equipment damage caused by short circuit of relay coil or abnormal power supply.

[0018] The magnetic adsorption design (with rubber pads) allows the remote control drive module to be quickly fixed to any metal surface of the interface cabinet, avoiding the instability of handheld operation.

[0019] The advantages of this utility model are: by adopting a split design for the signal computer interlocking interface cabinet relay remote control drive control module and relay acquisition module, this utility model can be conveniently fixed and achieve independent installation, maintenance and adaptation of each part, thus solving the problem of flexibility in the analog drive acquisition test of the signal computer interlocking relay circuit. This utility model adopts a split structure, which allows the control module and the acquisition module to be installed and connected independently. When a certain module fails, it can be disassembled and repaired or replaced separately, reducing the overall disassembly cost and improving maintenance efficiency. The aviation plug data acquisition module of this utility model is designed separately, making it more usable, portable, and practical. This invention achieves remote control and on-site inspection coordination through a drive control module and a data acquisition module, thereby improving the accuracy of fault diagnosis. This utility model features a split magnetic fixing structure, where two modules can be adsorbed into the optimal operating position, improving the convenience of construction.

[0022] like Figure 2 As shown, the remote control drive relay module 2 includes a housing 8.

The microcontroller unit 9 is a 32-bit remote control module, and the relay drive circuit 11 is a 32-bit wireless switching module. The remote controller 1 is wirelessly connected to the microcontroller unit 9 via the wireless communication module 10. The output terminal of the microcontroller unit 9 is connected to the input terminal of the relay drive circuit 11. The housing 8 is equipped with a 32-bit LED bead 12, a 32-bit aviation socket female connector 13, and a power input terminal 14. The power module 3 is connected to the power input terminal 14, which is also connected to the microcontroller unit 9. The 32-bit LED bead 12 is connected to the output terminal of the microcontroller unit 9, and the 32-bit aviation socket female connector 13 is connected to the output terminal of the relay drive circuit 11. The 32-bit aviation socket female connector 13 is connected to the relay circuit drive terminal 6 via an aviation plug cable 15. A power switch 20 is also provided on the housing.

[0023] A magnet is embedded on the back of the housing 8 of the remote control drive control relay module, and the remote control drive control relay module 2 is attached to the surface of the interface cabinet by the magnet.

[0024] A power switch is provided on the surface of the housing of the remote control drive control relay module.

[0025] like Figure 3 As shown, the acquisition and inspection display module 5 includes a housing 16, on which are provided a 32-bit aviation connector 17, a 32-bit status light 18, and a negative terminal 19. The positive terminals of the 32-bit aviation connector 17 and the 32-bit status light 18 are connected to each other, and the negative terminal of the 32-bit status light 18 is connected in series with the negative terminal 19. The negative terminal 19 is connected to the negative DC24V of the computer. The acquisition and inspection display module 5 is plugged into the acquisition terminal 7 of the relay circuit through the 32-bit aviation connector.

[0026] The relay drive circuit 11 has overcurrent protection of 10A and overvoltage protection of 275V.

[0027] (1) Remote control drive control relay module 2: The microcontroller unit 9, wireless communication module 10, and relay drive circuit 11 are designed as a control module, which uses a wireless communication protocol to drive the IO + DC24V power supply control output to the relay coil. The microcontroller unit adopts a 32-bit remote control type 1, and the relay drive circuit adopts a 32-bit wireless switch module and 32 corresponding display LEDs. It has an independent housing, is compact in size (34cm×15cm×12cm), and can be individually and fixed outside the interface cabinet 4 in a convenient position for operation. In actual use, the microcontroller adopts a 32-bit wireless control unit with a transmission distance of 20 meters. The relay drive circuit has overcurrent protection of 10A and overvoltage protection of 275V. The dimensions are 34cm×15cm×12cm, the shell is made of ABS plastic, and it is equipped with 32 LED relay status lights, 2 power input terminals, and 1 power switch. It also has a 32-position aviation socket female, which is independently fixed to the control panel of the combination cabinet through a magnetic structure.

[0028] A high-performance 32-bit remote control driver relay module 2 is selected as the core component. This module integrates a microcontroller unit, a wireless communication module, and a relay driver circuit. The microcontroller unit has powerful data processing capabilities, enabling it to quickly respond to and execute commands from the control terminal, precisely controlling the DC 24V drive of 32 relays. The wireless communication module adopts a stable and reliable communication protocol, such as Bluetooth or a dedicated wireless frequency band, ensuring stable and low-latency remote transmission of control commands. The relay driver circuit is optimized and features overcurrent and overvoltage protection functions, effectively ensuring the safe operation of the relays and the module itself, and achieving independent driving and precise control of each relay.

[0029] (2) Data collection and inspection display module 5: The data acquisition and display module 5 and the remote control drive relay module 2 are separately configured and directly plugged into the female terminal of the corresponding data acquisition aviation socket in the interface cabinet. This allows the system to acquire and observe the status of a relay after it is driven, thereby determining the correctness of the entire circuit. The device uses an integrated circuit design, reducing space and wiring requirements. It can be disassembled and replaced individually without disassembling the control module. An external I / O – DC24V is independently introduced.

[0030] In actual use, the dimensions are 12cm×5cm×1.5cm, the shell is made of ABS material, the aviation plug has 32 pins, the negative terminal of the internal circuit board is passed through to the outer shell and a negative terminal is reserved for easy connection to computer IO-DC24V; 32 fixed LEDs and leads are provided for easy connection with 32 male connectors.

[0031] To suit the characteristics of the signal interlocking interface cabinet, a compatible aviation plug interface was designed. The pin definitions, quantity, and electrical parameters of the aviation plug were determined to ensure the stability and reliability of the connection between the 32-bit acquisition, inspection, and display module 5 and the interface cabinet 4. The aviation plug adopts a high-protection-level design, possessing waterproof, dustproof, and vibration-resistant characteristics, adapting to the complex environment during railway signal construction and operation. Simultaneously, the plug and socket insertion and removal structure was optimized to enhance the tightness of the connection, avoiding signal transmission interruptions or poor contact caused by loosening, and ensuring accurate signal transmission between the control switch and the interface cabinet 4.

[0032] This utility model features a separate design for the remote control drive control relay module 2 and the data acquisition and display module 5, which facilitates individual maintenance and replacement and is compatible with different interface cabinet spaces. This utility model features a split-type magnetic fixing structure, allowing the acquisition, inspection, and display module 5 to be independently fixed in the optimal position, thus improving installation flexibility. The present invention provides a data acquisition and inspection display module 5, which simplifies the component replacement process during fault diagnosis.

[0033] like Figure 1 As shown, in actual use, the interface cabinet is connected to the combination cabinet and the computer interlocking cabinet at both ends. The combination cabinet contains relay circuits, and the status of signals, switches, and track circuits is connected to the relay circuits in the combination cabinet via relay contacts. The relay status in the combination cabinet (such as track occupancy, signal open, etc.) is connected to the interface cabinet via connectors. The computer interlocking system converts the signals from the combination cabinet into terminal signals (such as CPI series) recognizable by the interlocking cabinet input board through the interface cabinet, completing the standardized connection. The computer in the interlocking cabinet performs logical judgments based on the input signals and generates control commands (such as open signals, switchovers). The control commands are transmitted in reverse, driving the relays in the combination cabinet to operate, ultimately controlling the outdoor equipment. When the interlocking software is inadequate, this utility model's interface cabinet relay circuit drive inspection and testing device can be used to simulate and replace computer control. When using this device for simulation debugging, the interface cabinet and the computer interlocking cabinet must be disconnected.

[0034] Technicians attach the remote control drive relay module 2 to the operating surface of the combination cabinet and connect the drive's aviation plug cable to the drive end of the interface cabinet 4. The acquisition, inspection, and display module 5 is plugged into the acquisition terminal of the corresponding drive and connected to the negative power supply of the computer interlock IO. The remote control 1 sends drive commands to the remote control drive relay module 2 at one point or multiple points → the drive module transmits power to the relay coil in the combination cabinet → the relay is activated → the corresponding acquisition, inspection, and display module 5 acquires the status and provides feedback from the indicator light → the remote control drive relay module 2 analyzes and judges the status. If there is a wiring error, the corresponding indicator light goes out, realizing separate collaborative inspection and control.

[0035] In terms of appearance design, this utility model fully considers the usage requirements and ease of operation in railway signaling construction scenarios. The overall shape adopts a simple and regular rectangular design with precisely planned dimensions, which not only accommodates the internal functional modules but also facilitates installation and placement within interface cabinets and combination cabinets. The outer shell is made of high-strength, corrosion-resistant engineering plastic with a frosted surface treatment, which not only enhances the texture of the equipment but also effectively prevents scratches and wear. The front of the equipment features clear indicator lights and operation buttons. The indicator lights visually display the equipment's working status, wireless connection status, and relay drive status; the operation buttons are logically arranged, facilitating simple parameter settings and function operations for construction personnel, thus improving the human-machine interface experience.

[0036] To facilitate convenient mounting of the remote-controlled relay module 2 on the interface cabinet, a dedicated magnetic mounting structure was designed. Multiple strong magnets are embedded in the back of the module's housing. The magnets' magnetic force has been precisely calculated and tested to ensure the control switch is firmly attached to the interface cabinet housing while allowing for easy repositioning or removal by installation personnel. Simultaneously, a non-slip, insulating rubber pad is placed over the magnets to prevent scratches from direct contact with the cabinet housing and to enhance stability, preventing the control switch from shifting or falling off due to vibration. Furthermore, the magnetic mounting structure does not affect heat dissipation or signal transmission, ensuring stable operation of the control switch in its fixed state.

[0037] Based on the relay status monitoring results, the 32-bit remote control drive relay module 2 can make a preliminary judgment on the correctness of the equipment wiring. Through pre-set logic rules, it analyzes the correspondence between relay drive and status feedback. If a wiring error causes an inconsistency between drive and status, the corresponding indicator light on the device will turn off, indicating a potentially problematic line. This provides construction personnel with accurate clues for troubleshooting, effectively improving the efficiency and accuracy of wiring inspection.

[0038] A dedicated aviation connector for data acquisition and inspection was designed in conjunction with the interlocking data acquisition circuit. It uses an external negative DC24V input and determines the activation of the corresponding relay based on the load on the corresponding drive end. This device is compact, easy to plug and unplug, and can be flexibly applied in signal simulation inspection tests.

[0039] In conjunction with the aviation connector of interface cabinet 4, the circuit design of the acquisition indicator light was carried out, optimizing the vertical design to a horizontal design, while maintaining intuitive display and robust wiring.

[0040] Application effect Several railway signaling construction projects were selected as pilot projects to apply the 32-bit wireless control switch to the inspection of the drive relay circuit of the signal interlocking interface cabinet. During the pilot project, detailed records were kept of the ease of operation, problem-solving, and efficiency improvement data. Feedback and suggestions from construction personnel were collected to gain a deeper understanding of the actual application effects and shortcomings.
