Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit testing technology, and in particular to a portable master controller tester. Background Technology
[0002] The train main controller is the core component of train operation control, which is related to the normal operation and safety of the train. It controls the key operating states of the train, such as starting, acceleration, deceleration, and braking, and is a key device for the train to operate according to the line and timetable.
[0003] In actual operation, a malfunction in the train's main controller may lead to the evacuation of passengers or emergency rescue, affecting passenger travel and disrupting train operations. Furthermore, the repair period after a malfunction is lengthy, impacting normal train use and incurring high repair costs.
[0004] Current technology for train main controllers presents several challenges in testing and maintenance: First, the main controller has a complex structure with numerous contacts and requires high precision in its resistance output, making it difficult to test during routine train maintenance. Conventional maintenance methods are insufficient to meet these needs and accurately assess its actual operating status. Second, testing locations are limited. Precise testing requires disassembling components and placing them on a testing platform in a laboratory, resulting in a lengthy testing cycle and disrupting normal train operations. Third, when conducting rough, traditional tests on board, the accuracy is significantly compromised due to factors such as human measurement methods, potentially leading to undetected potential faults.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.
[0028] like Figure 1 As shown, a portable master controller tester includes a standard connection port assembly 1, a built-in measurement assembly 2, an external measurement assembly 3, a control assembly 4, a display assembly 5, and a power supply assembly 6. In this preferred embodiment, the master controller under test can be an ALSTOM master controller suitable for the 02A03 / 04 type train.
[0029] In one embodiment, such as Figure 2As shown, the standard connection port assembly 1 includes multiple standard connection ports, which are connected to the main controller under test (DUT). The built-in measurement assembly 2 includes a voltmeter, an ammeter, and an ohmmeter. The built-in measurement assembly 2 connects to the standard connection port assembly 1 to measure the basic electrical parameters of the DUT. The external measurement assembly 3 connects to the standard connection port assembly 1 at one end and to an external measuring instrument at the other end to measure other electrical parameters of the DUT. The control assembly 4 connects to the built-in measurement assembly 2 to control its measurement parameters. The display assembly 5 includes a voltmeter display panel, an ammeter display panel, and an ohmmeter display panel. The display assembly 5 connects to the control assembly 4 to display the basic electrical parameters of the control assembly 4. The power supply assembly 6 provides power to the portable DUT tester.
[0030] In one embodiment, the portable master controller tester further includes a housing, which includes a first panel 7, a second panel 8, and a housing frame. The first panel 7 and the second panel 8 are mounted on the housing frame. The first panel 7 is provided with an external measurement component 3, a control component 4, and a display component 5. The second panel 8 is provided with a standard connection port component 1. The power supply component 6 and the built-in measurement component 2 are disposed inside the portable master controller tester.
[0031] In one embodiment, the external measurement component 3 includes multiple extended test ports, which are connected to external measuring instruments. The electrical contacts of the extended test ports are gold-plated. The gold plating effectively reduces contact resistance, improves signal transmission performance, prevents oxidation and corrosion, and ensures the stability and accuracy of measurements during long-term use.
[0032] In one embodiment, the external measurement component 3 and the internal measurement component 2 are connected to the standard connector component 1 via internal wires, which are high-purity oxygen-free copper wires. The core advantage of using high-purity oxygen-free copper wires lies in their high conductivity, which reduces the internal resistance of the wire itself, thereby minimizing signal attenuation and loss during transmission and improving the fidelity and accuracy of the test results.
[0033] In one embodiment, the control component 4 includes multiple function selection switches, each corresponding to a different measurement parameter. Different measurement parameters are selected based on different measurement requirements to test the controller under test. Preferably, the function selection switches include electrical parameter buttons, such as voltage selection buttons, current selection buttons, and resistance selection buttons. Further, the function selection switches also include function test buttons, such as potentiometer test buttons, mode / direction handle test buttons, and solenoid valve test buttons. Further, the function selection switches also include status buttons, such as start buttons, stop buttons, and end buttons. Users can quickly and conveniently start the test process for specific parameters by pressing the corresponding function selection switch button according to the specific function points of the controller under test and different measurement requirements, without the need for complex settings.
[0034] In one embodiment, the standard connection port is an aviation connector, which connects to the aviation connector of the controller under test. This invention reduces resistance through direct connection, resulting in more accurate measurement results and avoiding the influence of objective factors such as poor contact and pin retraction on fault detection.
[0035] In one embodiment, the basic electrical parameters include potentiometer current output, directional handle resistance output, and solenoid valve status value. The potentiometer current output measures the signal current output from the main controller that drives the potentiometer-type sensor or actuator. The directional handle resistance output measures the resistance signal received by the main controller from the operating handle, representing the operating direction and force. The solenoid valve status value measures the voltage or current of the solenoid valve coil driven by the main controller, either digitally or analogally, to determine and indicate whether the solenoid valve is currently energized or de-energized. If the solenoid valve is energized, it is engaged, typically in the "open" state. If the solenoid valve is de-energized, it is disengaged, typically in the "closed" state.
[0036] The testing method of one embodiment of this utility model is as follows:
[0037] Taking the solenoid valve driven by the train's main controller as an example, the response status and performance of the solenoid valve under two operating conditions—normal power supply and undervoltage power supply—were verified using the portable main controller tester described in the aforementioned embodiment. The voltage under normal power supply is 110V, and the voltage undervoltage power supply is 84V.
[0038] The first step is to connect the main controller under test. Connect the corresponding aviation connector of the main controller under test to the aviation connector interface on the second panel 8 of the test instrument to ensure a reliable connection.
[0039] The second step is to select the solenoid valve test function and press the solenoid valve test button in the control component 4 area of the first panel 7 of the tester.
[0040] The third step is to set the test voltage conditions. Locate the voltage selection button in the control component 4 area. In the first condition, simulating normal train power supply, set the voltage selection to "110V". In the second condition, simulating undervoltage train power supply, set the voltage selection to "84V". Furthermore, this 84V-110V voltage is provided by the power supply component 6 and the voltage generation circuit of the built-in measurement component 2 within the tester, simulating the actual power supply voltage range of the train.
[0041] The fourth step is to start the test by pressing the start button. At this time, the tester will output the selected voltage to the solenoid valve under test through standard connection port component 1 and the main controller.
[0042] The fifth step involves real-time monitoring of multiple parameters. The display components 5 on the first panel 7 of the tester, namely the voltmeter, ammeter, and ohmmeter, will synchronize the basic electrical parameters.
[0043] Step 6: Stop the test and switch operating conditions. Press the stop button to turn off the drive voltage. The solenoid valve should disconnect and reset.
[0044] The seventh step is to repeat the test and comparison. Change the test voltage to 84V or 110V and repeat steps 4-6. Compare and observe the key indicators such as the solenoid valve's action time, pull-in current characteristics, and holding current stability under the two working conditions to determine whether its working performance under different power supply conditions meets the requirements.
[0045] This invention offers the following advantages: It supports dual-mode testing and multi-functional data reading, combining portability and ease of use. Firstly, it supports dual-mode measurement, allowing direct measurement using a built-in high-precision instrument or expansion testing via an external professional instrument interface, meeting different accuracy requirements and enhancing testing flexibility. Secondly, it efficiently and accurately reads various electrical parameters of the main controller, including the solenoid valve's operating status, potentiometer output characteristics, and the resistance value of the micro-switch on the direction control handle, providing data support for determining its operating status. Finally, its simple interface, compact size, and high portability make it convenient for on-site operation, overcoming spatial limitations and reducing reliance on fixed locations. Simultaneously, it optimizes adaptability to the working environment, reduces human error, avoids misjudgments due to operational or wiring errors, and improves the consistency, accuracy, and reliability of test results.
[0046] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and similar terms used in the description of this application should be interpreted broadly.
