Description

Technical Field

[0001] This utility model relates to the field of gate control unit testing technology, and in particular to an integrated hardware testing platform for gate control unit testing. Background Technology

[0002] With the rapid development of rail transit systems, platform screen doors (PSDs) are an important facility for ensuring passenger safety. The reliability and performance of their control unit—the Door Control Unit (DCU)—are of paramount importance. The DCU is responsible for precisely controlling the opening and closing of the platform screen doors, monitoring their operating status, and working in conjunction with other systems to ensure the stable operation of the platform screen doors under various working conditions. Therefore, during the production, maintenance, and upgrading of the DCU, it is necessary to conduct comprehensive and efficient testing to verify whether its functions meet the design requirements.

[0003] Traditional DCU testing methods typically rely on manual operation and simple testing tools, resulting in low testing efficiency, poor accuracy, and difficulty in simulating complex working conditions. For example, manual operation makes it difficult to accurately control the movement speed and position of the platform gate, and it is impossible to comprehensively test the control performance of the DCU under different working conditions. At the same time, manual recording of test data is prone to errors, and it is difficult to achieve real-time feedback and analysis of test results. Utility Model Content

[0004] In view of this, this utility model proposes an integrated hardware testing platform for gate control unit testing, which can effectively solve the shortcomings of the existing technology that cannot fully test the control performance of DCU under different operating conditions and that it is difficult to achieve real-time feedback and analysis of test results.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An integrated hardware test platform for gating unit testing includes:

[0007] DCU tray, used for securing and electrically connecting the gated unit under test;

[0008] Hardwired control buttons are used to provide input of door opening and closing commands, simulating control signal input in actual operation;

[0009] The motor drive mechanism is used to simulate the movement of the platform door and provide test conditions for the drive function of the door control unit under test.

[0010] Limit switches are used to detect the movement position of the simulated platform door in real time and feed the position signal back to the local control box;

[0011] The local control box is used to receive the operating status signal of the gate control unit and provide real-time feedback of the test results through the display.

[0012] A display screen is used to show real-time feedback test results;

[0013] The housing is used to mount and secure the DCU tray, hardwired control buttons, motor drive mechanism, limit switches, local control box, and display.

[0014] As a further optional embodiment of the integrated hardware test platform for gating unit testing, the test platform further includes:

[0015] An audible and visual alarm device is used to trigger an audible and visual alarm when an abnormality is detected in the gate control unit under test.

[0016] As a further optional solution for the integrated hardware test platform for gate control unit testing, the audible and visual alarm device adopts an audible and visual alarm indicator light, which is installed on the top of the housing.

[0017] As a further optional embodiment of the integrated hardware test platform for gating unit testing, the test platform further includes:

[0018] The network communication interface, which enables network transmission between the local control box and external devices, is mounted on the housing.

[0019] As a further optional embodiment of the integrated hardware test platform for gating unit testing, the test platform also includes a heat dissipation vent mounted on the housing.

[0020] As a further optional solution for the integrated hardware testing platform for gate control unit testing, the motor transmission mechanism includes a motor, a transmission shaft, a driven wheel, and a belt. The motor is connected to the driven wheel via the belt and drives the transmission shaft to rotate. The transmission shaft is connected to an external load via a flexible connector.

[0021] As a further optional solution for the integrated hardware testing platform for gate control unit testing, the motor transmission mechanism also includes a pad and a bearing. The pad is used to adjust the installation height and stability of the transmission shaft, and the bearing is used to support and stabilize the transmission shaft. The bearing is installed on the top of the pad.

[0022] As a further optional solution for the integrated hardware test platform for gate control unit testing, the motor transmission mechanism also includes an electromagnetic lock, which is used to mechanically lock the motor output shaft or transmission shaft in the motor transmission mechanism when the test platform is not in operation.

[0023] The beneficial effects of this utility model are as follows: The motor transmission mechanism can accurately simulate various motion conditions of the platform screen door, including different opening and closing speeds, accelerations, and load conditions. This allows the DCU's control performance to be comprehensively tested under various actual operating scenarios, thereby ensuring the stability and reliability of the DCU under various conditions. The real-time detection function of the limit switch ensures the accuracy of the DCU's control when the platform screen door moves to its limit position, further improving the comprehensiveness of the test. The local control box receives the DCU's operating status signal and provides real-time feedback of the test results through the display. This instant feedback mechanism allows operators to quickly understand the DCU's test status, promptly identify and resolve problems, and greatly improve testing efficiency. The housing integrates the DCU tray, hard-wired control buttons, motor transmission mechanism, limit switches, local control box, and display into a compact and efficient test platform. This integrated design simplifies the testing process, reduces equipment switching and connection time during testing, and improves testing efficiency. Attached Figure Description

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] refer to Figures 1 to 2 An integrated hardware test platform for gate control unit testing includes a DCU tray 2, hard-wired control buttons 3, a motor drive mechanism, limit switches 4, a local control box 5, a display 6, an audible and visual alarm device 7, a network communication interface 8, a heat dissipation vent 9, and a housing 1, wherein:

[0030] DCU tray 2 is used for fixing and electrically connecting the gate control unit under test. In some embodiments, DCU tray 2 integrates a DCU-specific adapter pluggable interface, which, together with a universal base, enables tool-less installation. After the gate control unit under test is placed on the tray, it can be directly connected to the power, communication, and I / O interfaces of the test fixture via quick plug-in, significantly improving testing efficiency. The tray design takes into account the differences in physical size and interface of different models of gate control units, and the adapter module enables compatible testing of multiple types of gate control units, expanding the application scope of the hardware test platform (such as gate control unit testing in fields such as high-speed rail sliding platform doors and subway platform screen doors). The DCU tray 2 is installed on the side of the housing 1.

[0031] The hard-wired control button 3 is used to provide the function of inputting door opening and closing commands, simulating the control signal input in actual operation; the hard-wired control button 3 is installed on the surface of the housing 1.

[0032] Specifically, the hard-wired control button 3 is used to provide the function of inputting door opening and closing commands. This design closely simulates the control signal input method in actual operation. Through hard-wired connection, it can ensure the stable and reliable transmission of control signals, thereby more realistically reflecting the control response of the door control unit in actual operation. This simulation method helps to discover control problems that may occur in the door control unit under real working conditions, such as signal delay and malfunction, and provides a strong test basis for the improvement and optimization of the door control unit.

[0033] The motor drive mechanism is used to simulate the movement of the platform door and provide test conditions for the drive function of the door control unit under test. In some embodiments, the motor drive mechanism includes a motor 10, a drive shaft 11, a driven wheel 12 and a belt 13. The motor 10 is connected to the driven wheel 12 through the belt 13 and drives the drive shaft 11 to rotate. The drive shaft 11 is connected to an external load through a flexible connector 17. The motor drive mechanism is installed in the housing 1.

[0034] Specifically, the motor drive mechanism is designed to simulate the movement of the platform screen door. The motor 10 is connected to the driven wheel 12 via the belt 13, driving the drive shaft 11 to rotate. This allows for the precise reproduction of the dynamic process of opening and closing the platform screen door. This accurate simulation places the gate control unit (DCU) under test in a near-realistic working environment, enabling more accurate testing of the DCU's ability to control the movement of the platform screen door in actual operation, including whether the control of the platform screen door's start, stop, and speed adjustment meets the requirements. Because the motor's speed and direction can be controlled, this mechanism can simulate the movement of the platform screen door under different working conditions, such as normal speed opening and closing, rapid opening and closing, and braking in emergency situations. This provides the possibility for comprehensive testing of the performance of the DCU under various complex working conditions and helps to identify potential problems with the DCU in different scenarios.

[0035] To provide test conditions for the drive function of the gate control unit under test, the drive shaft 11 is connected to an external load through a flexible connector 17, which can simulate the actual load conditions when the platform door moves. Under such conditions, the gate control unit can be tested to truly verify its drive capability, adaptability to load changes, and control stability under different loads, ensuring that the gate control unit can reliably drive the platform door in practical applications. With the help of precise control and simulation of the motor drive mechanism, various performance indicators of the gate control unit can be easily measured and evaluated, such as the stability of drive current and voltage, and the accuracy of platform door position control. These data are crucial for evaluating the quality and performance of the gate control unit and help to select high-performance gate control unit products.

[0036] In some embodiments, the motor transmission mechanism further includes a pad 14 and a bearing 15. The pad 14 is used to adjust the installation height and stability of the transmission shaft 11, and the bearing 15 is used to support and stabilize the transmission shaft 11 to reduce rotational friction. The bearing 15 is mounted on the top of the pad 14.

[0037] Specifically, the shim 14 is used to adjust the installation height of the drive shaft. This design allows the motor drive mechanism to adapt to different testing environments and installation requirements. At the same time, the shim 14 helps improve the installation stability of the drive shaft 11. It can fill the gaps during the installation process, reduce the shaking and displacement of the drive shaft 11 during operation, and provide a stable installation base for the drive shaft 11.

[0038] The main function of bearing 15 is to support and stabilize transmission shaft 11. During the operation of the motor transmission mechanism, transmission shaft 11 needs to withstand various forces, including the torque transmitted by the motor and the reaction force of external loads. Bearing 15 can effectively support transmission shaft 11, so that it maintains a stable axial position during rotation, reduces shaft bending and deformation, and ensures transmission accuracy and efficiency. At the same time, it can reduce the frictional resistance between transmission shaft and support components, reduce energy loss, and improve the transmission efficiency of motor transmission mechanism.

[0039] In some embodiments, the motor drive mechanism further includes an electromagnetic lock 16, which is used to mechanically lock the motor output shaft or drive shaft 11 in the motor drive mechanism when the test platform is not in operation.

[0040] Specifically, when the test platform is not being tested, the electromagnetic lock 16 can mechanically lock the motor output shaft or transmission shaft 11. This effectively prevents the motor from starting unexpectedly due to human error, equipment failure or other unforeseen factors when not in a test state, thereby driving the transmission mechanism to operate. This ensures the personal safety of personnel at the test site and avoids accidents such as collisions and squeezing caused by suddenly operating mechanical parts.

[0041] Limit switch 4 is used to detect the movement position of the simulated platform door in real time and feed the position signal back to the local control box. In some embodiments, limit switch 4 detects the movement position of the simulated platform door (such as fully open or fully closed) in real time through mechanical contacts or sensors and feeds the position signal back to the local control box. When the door moves to the limit position, the limit switch triggers a power-off or stop command to prevent motor overload or damage to mechanical parts. At the same time, by simulating limit switch failure scenarios (such as signal loss or false triggering), the fault-tolerant logic and safety protection mechanism of the DCU under abnormal operating conditions can be verified. In automated testing, the signal of the limit switch is used as the basis for judging test items (such as door opening and closing time and position accuracy). The limit switch 4 is installed on the surface of the housing 1.

[0042] The local control box 5 is used to receive the operating status signals of the door control unit (such as door position signal, fault alarm, etc.) and to provide real-time feedback of test results through the display 6; the local control box 5 is installed on the surface of the housing 1.

[0043] Specifically, the local control box 5 can receive various operating status signals from the door control unit (DCU), such as door arrival signals and fault alarms. This allows the test platform to fully grasp the working status of the DCU, timely acquiring both normal door opening and closing status information and abnormal fault information. It can accurately process the various received signals and convert them into a form that can be displayed and judged. For example, processing the door arrival signal can accurately determine whether the platform door has reached the predetermined position; processing the fault alarm signal can quickly identify the fault type and occurrence time, improving the efficiency and accuracy of fault diagnosis.

[0044] By connecting to the display 6, the local control box 5 can provide real-time feedback of the processed test results to the operator. The operator can understand the operating status and test situation of the DCU immediately, and promptly identify potential problems without having to wait for the test to end before reading and analyzing the data, which greatly improves the timeliness of the test.

[0045] Display 6 is used to display real-time feedback test results; the display 6 is installed between the top of the housing 1 and the audible and visual alarm device 7.

[0046] The audible and visual alarm device 7 is used to trigger an audible and visual alarm when there is an abnormality in the gate control unit under test.

[0047] In some embodiments, the audible and visual alarm device 7 uses an audible and visual alarm indicator light, which is installed on the top of the housing 1.

[0048] Specifically, the display 6 can display the test results of the gate control unit (DCU) in real time. Operators can view the various performance parameters and operating status of the DCU at any time. This helps to identify problems that occur during the test in a timely manner, such as whether the control signal of the DCU is normal or whether the control of the platform door movement is accurate, so as to make quick adjustments and decisions.

[0049] When an abnormality occurs in the gate control unit under test, the audible and visual alarm device 7 can immediately sound an alarm. This timely alarm method can quickly attract the attention of the operator, enabling them to take measures to address the abnormality as soon as possible, such as pausing the test, checking the cause of the DCU malfunction, etc., to prevent the abnormality from worsening and reduce potential losses. The use of audible and visual alarm indicator lights allows different alarm states to be distinguished by different colors and flashing frequencies. Combined with the sound alarm, it can more clearly indicate to the operator the type and severity of the DCU abnormality, which helps to quickly locate and resolve the problem.

[0050] The network communication interface 8 is used to realize the network transmission function between the local control box 5 and external devices, and is installed on the surface of the housing 1.

[0051] Specifically, the network communication interface 8 enables the local control box 5 to transmit data to external devices via the network. This means that the test platform can establish a connection with a host computer, server, or other remote monitoring equipment. Operators can obtain test data of the gate control unit (DCU) in real time from a remote location, such as operating status signals and test results, without having to be physically present at the test site, which greatly improves the flexibility and efficiency of monitoring.

[0052] Heat dissipation vent 9 is installed at the bottom of the housing 1.

[0053] The housing 1 is used to install and fix the DCU tray 2, hard-wired control button 3, motor drive mechanism, limit switch 4, local control box 5, display 6, audible and visual alarm device 7, network communication interface 8, and heat dissipation vent 9.
