Description

Technical Field

[0001] This utility model relates to the technical field of railway vehicle-mounted equipment testing devices, specifically to an intelligent electrical control vehicle-mounted equipment multi-channel hot standby device. Background Technology

[0002] With the rapid development of railway transportation, electrical engineering equipment (including locomotive signaling devices, train operation monitoring and recording devices (LKJ), self-propelled equipment operation monitoring devices (GYK), and CIR radio equipment) is a core component ensuring the safe operation of trains. Its stability and reliability directly determine the safety level and operational efficiency of railway transportation. To ensure timely and effective handling and replacement of various onboard equipment malfunctions, each electrical engineering workshop must pre-stock fully functional LKJ monitoring devices, locomotive signals, and other spare equipment at equipment repair points to replace faulty equipment at any time.

[0003] Currently, although single-channel on-board equipment testers have emerged in China, when testing one on-board device, other on-board equipment spares are stored in a "cold standby" manner, meaning the equipment is stored without power. When replacing the on-board equipment under test, the tested equipment must be removed, and the new equipment reconnected to power for testing, making the switching process time-consuming. This severely restricts the efficiency of railway on-board equipment maintenance and testing, especially when facing large-scale, high-efficiency testing demands. Existing on-board equipment testing devices only provide power and some signal conditions to the on-board equipment, failing to simulate the actual operating environment of the equipment during use, thus hindering real-time and comprehensive testing of the on-board equipment's electrical performance.

[0004] While single-channel onboard equipment testing instruments have emerged in China, significant technical limitations remain in practical applications. Firstly, equipment turnover efficiency is low. When testing a single onboard device, the remaining backup equipment must be stored in a "cold standby" state—meaning it is stored without power. In this mode, after testing each device, the operator must first remove the tested device, disconnect the power connection, and then reconnect and initialize the new device. In batch testing scenarios, the time cost of such repetitive operations accumulates linearly, severely limiting the daily testing volume and failing to meet the timeliness requirements of large-scale maintenance by railway departments.

[0005] Secondly, the testing environment is out of sync with actual operating conditions. Existing testing instruments can only provide basic power and simple signal input, and cannot reproduce the real operating conditions of vehicle-mounted equipment: the ambient temperature of vehicle-mounted equipment during normal use is high and constantly changing; however, existing vehicle-mounted equipment testing devices do not simulate this temperature environment. Utility Model Content

[0006] The purpose of this utility model is to overcome the problems in the prior art and provide an intelligent multi-channel hot standby device for electrical vehicle equipment.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an intelligent on-board equipment multi-channel hot standby device for electrical systems, comprising an on-board equipment testing module, a temperature control module, and a hot standby area; the on-board equipment is stored in the hot standby area, allowing simultaneous hot standby of three sets of on-board equipment, all three sets of on-board equipment being connected to the on-board equipment testing module; the on-board equipment testing module includes a main control motherboard, a display, and an analog control plug-in, both of which are connected to the main control motherboard; a heater is provided in the hot standby area, and the heater is connected to the temperature control module; a temperature sensor is provided in the hot standby area, and the temperature sensor is connected to the temperature control module; a high-temperature alarm device is connected to the temperature control module.

[0008] Furthermore, the analog control module includes an analog quantity board, a digital quantity board, and a signal acquisition board, which are connected to the main control unit motherboard via an RS485 bus.

[0011] Furthermore, the display is a touch screen.

[0012] Furthermore, a fan is provided in the hot standby area.

An AC contactor and a solid-state relay are also provided between the PID control module and the fan.

[0014] Furthermore, the heater is a ceramic PTC heater.

[0015] Furthermore, the temperature sensor is a type K thermocouple.

[0016] Furthermore, the high-temperature alarm device includes an indicator light and a buzzer.

[0017] This utility model is an intelligent multi-channel hot standby device that can simultaneously support hot standby of 3 sets of vehicle-mounted equipment. Its beneficial effects are as follows: 1. The device can provide hot standby support for 3 sets of vehicle-mounted equipment at the same time. After testing one device, it can quickly switch to another vehicle-mounted device for testing, avoiding the problem of wasting time due to complicated operation procedures when changing vehicle-mounted equipment.

[0018] 2. This device automatically adjusts the heating output power through PID calculation, keeping the hot standby area in a dynamic temperature adjustment state, which can accurately simulate the high-temperature environment of a locomotive. This feature provides reliable experimental conditions for testing the operation of onboard equipment in the high-temperature environment of a locomotive, and helps to comprehensively verify the performance stability and reliability of onboard equipment in extreme temperature environments.

[0019] 3. In addition, the temperature of the hot standby area is monitored in real time by sensors. When the temperature exceeds the set value by 2°C, the high temperature alarm device will immediately activate the audible and visual alarm, which can quickly remind the staff to deal with it in time and effectively prevent the equipment from being damaged by continuous high temperature, providing double protection for equipment safety.

[0020] 4. The signal acquisition board can collect the status information of the vehicle-mounted equipment in real time, and the test information can be displayed intuitively on the screen, so that the staff can grasp the operating status of the vehicle-mounted equipment in a timely and clear manner, which can facilitate the early detection of potential problems and ensure that the performance of the vehicle-mounted equipment put into use fully meets the standards, laying a solid foundation for the safe and stable operation of the equipment.

The onboard equipment is stored in the hot standby area 3, allowing simultaneous hot standby of three sets of onboard equipment (the three sets can be arbitrarily selected from four types of equipment: LKJ, locomotive signal, CIR, and GYK; they can be a combination of three different types of equipment or three types of the same equipment). All three sets of onboard equipment are connected to the onboard equipment testing module 1. The onboard equipment testing module 1 includes a main control motherboard 4, a display 5, and an analog control module. The display 5... Both the analog control plug-in and the analog control plug-in are connected to the main control motherboard 4. The analog control plug-in simulates and generates various signals required by the vehicle equipment and displays the test information through the display 5. The hot standby area 3 is equipped with a heater 6, which is connected to the temperature control module 2. By controlling the operation of the heater 6, the temperature of the hot standby area 3 is controlled. The hot standby area 3 is equipped with a temperature sensor 7, which is connected to the temperature control module 2 and feeds back the temperature of the hot standby area 3 to the temperature control module 2. The temperature control module 2 is connected to a high temperature alarm device 12, which will trigger an audible and visual alarm when the temperature reaches a high level.

[0027] The analog control module includes an analog quantity board 8, a digital quantity board 9, and a signal acquisition board 10. The analog quantity board 8, digital quantity board 9, and signal acquisition board 10 are connected to the main control motherboard 4 via an RS485 bus for communication. The signal acquisition board 10 acquires 24 channels of 110V digital signals (emergency, reduced voltage, reduced voltage closed, air shut-off, backup 0, backup 1, backup 2) from three vehicle-mounted devices (LKJ). For example, when the vehicle-mounted device is in an emergency, it will send a 110V digital signal, which will be acquired by the signal acquisition board 10.

[0028] The vehicle-mounted equipment testing module 1 also includes a system power supply 11, which comprises three sets of DC 110V power supplies, one set of DC 50V power supplies, and one set of DC 24V power supplies. The three sets of DC 110V power supplies are used to power the vehicle-mounted equipment, the one set of DC 50V power supplies is used to provide operating conditions for the LKJ, and the one set of DC 24V power supplies is used to power the analog control module.

[0029] The vehicle-mounted equipment and the vehicle-mounted equipment test module 1 are connected via two 50-core cables. Each cable contains speed, pressure, operating condition, carrier frequency signal lines, and a CAN bus. Each 50-core cable's CAN bus contains four signal lines, and the switching between the two CAN bus lines is accomplished via a four-pole double-throw relay.

[0030] The display 5 is a touch screen.

[0031] The hot standby zone 3 is equipped with a fan 13. It provides an air source, promotes air circulation, and ensures uniform heating.

[0032] The high temperature alarm device 12 includes an indicator light and a buzzer to realize audible and visual alarm. When the temperature exceeds the set temperature by 2°C, the audible and visual alarm will be activated.

[0033] like Figure 2 As shown, the temperature control module 2 includes a temperature controller touchscreen 14 and a PID control module 15. The temperature controller touchscreen 14, heater 6, and fan 13 are all connected to the PID control module 15. An AC contactor and a thermal relay are also provided between the PID control module 15 and the heater 6, and an AC contactor and a solid-state relay are also provided between the PID control module 15 and the fan 13. The heating output power is automatically adjusted through PID calculation to control the heater 6 output to reach the set value (sp) temperature and maintain a constant temperature. If the temperature of the hot standby zone 3 exceeds the set temperature by 2°C, a buzzer and indicator light will activate a high-temperature alarm. The PID control module 15 is controlled by the on-board equipment test module 1, and the two communicate via an RS485 bus.

[0034] The temperature sensor 7 is a type K thermocouple.

[0035] The heater 6 is a ceramic PTC heater. PTC heaters have a series of advantages that traditional electric heating elements cannot match, such as constant temperature heating, long natural life, energy saving, no open flame, good safety performance, easy adjustment of heat output, and less impact from power supply voltage fluctuations.

[0036] Working principle:

[0037] 1) Testing of vehicle-mounted equipment (LKJ):

[0038] Manual Test: Select a vehicle-mounted device (LKJ) and send various signals (locomotive signal, handle condition signal, speed signal, diesel speed signal, track signal, pipe pressure signal, primary voltage, primary current signal) to the LKJ vehicle-mounted device via the touch screen 5 and analog signal board 8. The vehicle-mounted device (LKJ) outputs corresponding switch signals. The switch signals output by the vehicle-mounted device (LKJ) (emergency, unload, depressurization, air shut-off, air shut-off, backup 0, backup 1, backup 2) are sent to the industrial control computer motherboard 4 via RS485 communication through the signal acquisition board 10 of the vehicle-mounted device test module 1. The industrial control computer motherboard 4 simultaneously obtains the operating information of the vehicle-mounted device (LKJ) through the CAN bus and performs analysis and judgment. The normality of the signal can be determined by the display on the monitor 5.

[0039] Automatic Testing: The main control motherboard 4 can be configured with automatic testing software. Users can select the test items to be performed on the vehicle-mounted equipment (LKJ), and the software on the touchscreen display 5 controls the vehicle-mounted equipment testing module to enter automatic testing mode. The vehicle-mounted equipment testing module 1 provides various signals to the vehicle-mounted equipment (LKJ) according to the user-selected test items and obtains the vehicle-mounted equipment (LKJ) operating information via the CAN bus. The CAN buses of the three vehicle-mounted devices are switched via relays, ensuring that only one vehicle-mounted device communicates with the vehicle-mounted equipment testing module at a time.

[0040] 2) Testing of onboard equipment (locomotive signaling devices):

[0041] Select an on-board device (locomotive signaling device), and send a carrier frequency signal to the locomotive signaling device through the analog signaling board 8 via the touch screen 5. Determine whether the signal is normal by observing the display of the eight-sided indicator lights on the locomotive signaling device or the color lights on the connected on-board device (LKJ).

[0042] 3) Testing of in-vehicle equipment (GYK):

[0043] Manual test: Select a vehicle-mounted device (GYK), and send various signals (locomotive frequency signal, handle condition signal, speed signal, pipe pressure signal) to the GYK vehicle-mounted device through the analog board 8 via the touch screen 5. The vehicle-mounted device (GYK) outputs the corresponding switch signals. The switch signals output by the vehicle-mounted device (GYK) (emergency, unload, depressurization, air shut-off, air shut-off, backup 0, backup 1, backup 2) are sent to the industrial control computer motherboard 4 via RS485 communication through the signal acquisition board 10 of the vehicle-mounted device test module 1. The industrial control computer motherboard 4 simultaneously obtains the operating information of the vehicle-mounted device (LKJ) through the CAN bus and performs analysis and judgment. The normality of the signal can be judged by the display on the monitor 5.

[0044] Automatic Testing: The main control motherboard 4 can be configured with automatic testing software. Users can select the test items for the vehicle-mounted equipment (GYK), and the software on the touchscreen display 5 controls the vehicle-mounted equipment testing module to enter automatic testing mode. The vehicle-mounted equipment testing module 1 provides various signals to the vehicle-mounted equipment (GYK) according to the user-selected test items and obtains monitoring device operation information via the CAN bus. The CAN buses of the three vehicle-mounted devices are switched via relays, ensuring that only one vehicle-mounted device communicates with the vehicle-mounted equipment testing module at a time.

[0045] 4) Testing of in-vehicle equipment (CIR):

[0046] Select a vehicle-mounted device (CIR), and input DC110V power to the CIR host through the touch screen 5 and the switch board. Use the CIR device self-test to determine if the function is normal.

[0047] 5) Working principle of the temperature control section:

[0048] Temperature control module 2 controls the temperature of hot standby zone 3 to simulate the locomotive environment temperature, thereby verifying the operation of onboard equipment under locomotive conditions and reducing the failure rate of onboard equipment. Setting a high-temperature alarm point can effectively protect the normal operation of the equipment.

[0049] The temperature control of the hot standby zone 3 is constructed using a configuration of a temperature controller touchscreen 14 + PID control module 15 + heater 6 + temperature sensor 7 + fan + AC contactor + thermal relay + solid-state relay + human-machine interface touch controller (touch display 5 of vehicle-mounted equipment test module 1). It automatically adjusts the heating output power through PID calculations to control the electric heater output to reach and maintain the set temperature (sp). When the temperature exceeds the set temperature by 2°C, an audible and visual alarm is triggered.
