[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] This utility model discloses a programmable door controller port function tester, comprising a main unit with a chassis and a front panel. The chassis houses a main unit control circuit board and a DC power supply, and also includes a power socket. The front panel includes a power switch, a grounding post, an LCD touchscreen, an input detection port, an output control port, and a communication port. The main unit control circuit board is connected to the DC power supply, the LCD touchscreen, the input detection port, the output control port, and the communication port. The DC power supply is connected to the power socket, the power switch, and the main unit control circuit board. The power socket is connected to the DC power supply, the power switch, and the grounding post. The main unit's input detection port and output control port are connected to the door controller under test via wiring harnesses. The door controller is connected to a motor via wiring harnesses. The power socket is connected to an external 220V power supply.

[0021] During use, operators use dedicated wiring harnesses to connect the input detection port to the gate controller's output signal, and the device's output control port to the gate controller's input and power signals. The motor is directly connected to the gate controller's motor control interface.

[0022] During testing, the output control port supplies power to the gate controller, simulating voltage changes in various train signals and mechanism switch signals to the gate controller's signal port. Simultaneously, the input detection port monitors the voltage changes from the gate controller's control signal port in real time. The equipment indicates, stores, and records all signal states. Before starting the test, the equipment can program the parameters of each signal of the gate controller according to the actual situation, setting the change state values ​​and reference values.

[0023] Two testing modes are available: manual and automatic. In manual mode, the equipment simulates the voltage changes of various train signals and mechanism switch signals. All signal change triggers are manually controlled by the operator, similar to mechanical button operation. The operator determines whether the gate controller port is functioning correctly by observing the port signal response. In automatic mode, the trigger conditions for each signal change need to be set in advance (trigger state, duration, off-time, cycle period and number of times, associated signals, etc.). After starting the test, the equipment automatically outputs the trigger signal without operator intervention, displaying the waveform status of the signal changes in real time. Based on preset values, it automatically determines the dynamic stability of the gate controller port.

[0024] Example:

[0025] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 With appendix Figure 4The detection connection method in this embodiment is as follows: 1) Connect the AC power supply to the power socket of the chassis using a power cord to provide AC 220V AC mains power to the device. 2) Use a dedicated connection harness to connect the output signal of the door controller under test (e.g., door opening / closing indicator light, buzzer, electromagnet, side door light, etc.) to the input detection port on the device panel; connect the input signal of the door controller under test (e.g., lock position switch, closed position switch, zero speed, centralized control door opening, etc.) and the power signal (positive power, negative power) to the output control port; connect the motor control interface (motor control line, encoder signal line) of the door controller under test directly to the corresponding model of motor.

[0026] Comparison Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 The main unit of this utility model mainly includes a chassis, a panel, a main unit control circuit board, an LCD touch screen, a DC power supply, a communication port, an input detection port, an output control port, a power socket, a power switch, and a grounding post.

[0027] The power switch on the panel controls the DC flow control power input. The 220V AC power is converted to DC 110V by the DC flow control power supply, which powers the main control circuit board and the gate controller under test. The 110V power supply is connected to the voltage conversion circuit on the main control circuit board, and after conversion, it outputs DC 12V, 5V, and 3.3V power.

[0028] The LCD touch screen uses a 10-inch industrial-grade serial port LCD screen with capacitive touch technology. Together with the LCD touch screen driver circuit on the host control circuit board, it enables human-computer interaction functions such as real-time data display, parameter setting, and test start.

[0029] The DC flow control power supply is connected to the power socket and the communication circuit 1 (RS232) on the host control circuit board to realize the programmable adjustment of the DC 110V output voltage (77V to 132V) and simulate the changes in the input and output of the gate controller under the condition of power supply voltage fluctuation.

[0030] The panel's input detection port uses a 10-pin aviation socket, connecting to the input detection circuit on the main control circuit board to achieve 10-channel DC voltage on / off status detection. The panel's output control port uses a 24-pin aviation socket, connecting to the output control circuit and relay control circuit on the main control circuit board to achieve 24-channel DC voltage output control, with one relay control circuit controlling the power-on of the gate controller under test. The panel's communication port uses a 5-pin aviation socket, connecting to communication circuit 2 (RS485) on the main control circuit board.

[0031] The main control circuit board has a core board processor circuit, using a 32-bit microprocessor chip. Through software programming, it performs the following processing: 1) Determines the trigger edge (rising edge, falling edge) of the input signal and calculates the pulse period; 2) Controls the on-time and off-time of the output signal; 3) Controls the output and off-time according to the trigger sequence based on the preset relevant signal logic association parameters; 4) Generates waveforms for the current detection data, compares them with preset parameter values, and alarms for out-of-tolerance data.

[0032] The host control circuit board is equipped with a FALSH memory circuit and a TF card circuit, enabling real-time recording and storage of all input detection signals and output control signals.

[0033] This invention features an LCD touchscreen display and multiple signal connection ports (24 output ports and 10 input ports), enabling parameter setting. Operators can program and define each signal port to achieve compatible detection of multiple line gate controllers. The output ports utilize power MOSFET control, allowing for controllable output delays. Output modes (level and pulse) and associated trigger conditions can be programmed to meet complex timing triggering and multi-signal associated triggering requirements. Input port detection employs optocoupler isolation and LCD icon display, enabling the detection of signal change cycles to meet the needs of action delay measurement and associated logic judgment. All detection data is recorded in real time, and the process and results can be automatically compared and judged against preset programming parameters, achieving a standardized detection process and significantly improving detection efficiency.
