[0021] Figure 2 This is the left view of the utility model of this application. DETAILED DESCRIPTION
[0022] The following is combined with Figure 1-2 This application is described in further detail.
[0023] The embodiment of the present application discloses an electric passenger car door operation test control system.
[0024] Reference Figure 1The electric passenger car door operation test control system includes a box (1), a microcomputer control unit arranged in the box (1), and a circuit automatic control unit. The box (1) panel is provided with a display screen (2), a "plus" key (3), a "set" key (4), a "minus" key (5), a "start" key (6), a "clear" key (7), a "stop" key (8), a left door closed indicator light (9), a door permission indicator light (10), a right door closed indicator light (11), a left door opening counter (12), a right door opening counter (13), a left door opening counter reset button (14), a right door opening counter reset button (15), a left door closing counter (16), a right door closing counter (17), a left door closing counter reset button (18), and a right door closing counter reset button (19). The microcomputer control unit arranged in the box (1) is programmed with a logic control program. The circuit automatic control unit arranged in the box (1) is composed of an input DC transformer, an energized time delay relay, a contactor, and a circuit protection element.
[0025] refer to Figure 2 The left side shell of the box (1) is provided with a system power switch (a) and an integrated plug connection port (b) for connecting the system to the main door controller (MDCU) of the electric passenger car door. The system is connected to the electric passenger car door system via an integrated plug and cable provided outside the box.
[0026] The working principle of the utility model is as follows: the control system integrated plug is inserted into the left and right main door controller (MDCU) terminal blocks of the electric passenger car; the left and right main door controllers (MDCU) provide DC110V power supply to the control system through the connecting cable, and the control system uses the input DC transformer to convert DC110V into DC24V automatic circuit working voltage and DC5V microcomputer working voltage; the target test number is set by the "set" key (4), "plus" key (3), and "minus" key (5) on the panel of the box (1), and the test is started by the "start" key (6); the display screen (2) displays the set running number and the completed running number; the circuit automatic control system set in the box (1) is automatically turned on and off. The control unit outputs the corresponding high / low level command to control the door switch; the test process monitoring unit displays the test data such as the number of door opening / closing command transmissions, the actual number of door opening / closing operations, and the left / right door switch status in real time through the left door closed indicator light (9), the door allowed indicator light (10), the right door closed indicator light (11), the left door opening counter (12), the right door opening counter (13), the left door closing counter (16), and the right door closing counter (17); when the number of completed operations displayed on the display screen (2) is equal to the set number of operations, the control circuit automatically operates the control unit to stop sending the door opening and closing high level commands. At the same time, the system operation can also be stopped by the "stop" key (8) during the process.
[0027] This new system features a highly integrated design that integrates control logic and monitoring technology, greatly simplifying operation and maintenance. The system uses a data processing control unit to accurately interpret and execute instructions from the operator interface.
[0028] The system also features an integrated plug design, ensuring a secure and reliable electrical connection, facilitating installation, commissioning, and subsequent maintenance. Operators utilize a simple interface to precisely control the opening and closing of all doors on the electric train, including both independent control of individual doors and coordinated control of all doors on the train. Furthermore, the system includes comprehensive process status monitoring, enabling real-time acquisition and display of key parameters during the door opening and closing process, such as the number of door openings and closings.
[0029] Compared to traditional manual door button operation, this system demonstrates significant automation advantages. Through automated control technology, the system fully automates door opening and closing operations, significantly shortening test cycles and significantly improving test efficiency. Automated control not only reduces operational delays or errors caused by human factors but also ensures accuracy and consistency in door opening and closing through precise timing and process optimization.
[0030] This system operates unattended. Once the test parameters and procedures are set, it autonomously completes the door switch test without the need for on-site monitoring. This unattended operation reduces reliance on manpower and mitigates safety risks caused by fatigue or negligence, further improving operational safety and reliability. From a cost-effectiveness perspective, this system reduces labor and material costs.
[0031] The system's controller buttons are designed for user-friendliness and comprehensive functionality. By combining buttons, operators can precisely adjust the number of door openings and closings, enabling flexible control of the test process. This adjustment capability not only meets the diverse needs of different test scenarios, but also ensures accurate and repeatable test results.
[0032] The door-closed indicator is a key indicator of status visualization. When a door is successfully closed and locked, the indicator illuminates, providing the operator with door status information. This intuitive status feedback mechanism improves system safety and simplifies operator monitoring, allowing them to quickly determine door status and take necessary action.
[0033] The system is also equipped with a digital display that counts and displays door opening and closing times in real time. The display interface is concise and clear, presenting all data in clear and intuitive digital form, allowing operators to accurately grasp test progress and results. This real-time data statistics function improves operational efficiency and provides a reliable basis for subsequent data analysis and reporting.
[0034] The control system's cabinet is professionally designed, compact and lightweight, ensuring easy portability for operators. The arrangement and routing of electrical components within the cabinet are optimized, and most components utilize universal parts, ensuring system stability, reliability, and maintainability.
[0035] The system's layout combines aesthetics with practicality. Control elements such as buttons, knobs, and switches are arranged according to conventional operating logic and sequence, enabling operators to quickly locate the required controls and complete various operations. The control elements' exterior and color design aligns with the original electric bus design, aligning with operator preferences.
[0036] The display is embedded in the cabinet surface, making the system smooth and coordinated. The display interface is simple and clear, and important information is highlighted, making it easy for operators to obtain the required data.
[0037] The system integrates a power-off protection mechanism to ensure safe and orderly execution of protective measures in the event of any unexpected or intentional interruptions during the test process. If an unexpected situation occurs during the test process, causing an interruption, the system immediately activates its built-in power-off protection logic, delaying the operation of relays and circuit breakers to achieve a smooth transition and delay control of the power-off process.
[0038] During the test, the microcomputer control unit, serving as the core control, monitors the system's operating status in real time and quickly issues a termination command upon receiving a power-off signal. Crucially, the microcomputer control unit ensures that the final control command issued upon test termination is always the door-closing command. This design ensures that even in an emergency, the active doors can be smoothly closed under the control command, thereby maintaining the safety and integrity of the test environment. Furthermore, the system incorporates fuse and diode protection mechanisms to ensure safety and reliability.
[0039] This system utilizes single-chip microcontroller (MCU) control technology to precisely control and arbitrarily set command intervals. The MCU receives and interprets commands from the user or a pre-programmed program. Using an internal timer and an external clock source, it accurately measures and controls the intervals between each door opening and closing command. Operators can dynamically adjust the intervals between door opening and closing commands by directly inputting the desired command intervals through the human-computer interface or selecting a preset interval mode based on experimental requirements. The entire system is highly flexible, adapting to varying door models and complex, changing operating conditions, while minimizing the need for specialized operator skills.
[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
