Description

Technical Field

[0001] This utility model belongs to the field of rail transit equipment testing technology, and in particular relates to a door unit control board and a gate sensor group testing device. Background Technology

[0002] Currently, the ticket gates used in rail transit consist of two gate panels, one on the left and one on the right, with door units installed in each panel. When a pedestrian enters the passage without authorization, the door unit detects the unauthorized access through sensors installed inside the gate channel. At this point, the door unit opens its blades to prevent the unauthorized person from passing through.

[0003] Specifically as follows:

[0004] The left and right turnstiles are equipped with transmitters and receivers of through-beam infrared photoelectric sensors, respectively. The transmitters emit invisible infrared light, which is received by the receivers. After a pedestrian enters the passage, their body, belongings, and luggage will block different combinations of sensors in stages, thus forming different zone status parameters. The signals output from the sensor receivers are sent to a microprocessor, and the microprocessor outputs signals to the gate unit control unit (GCU) and the industrial control computer. The gate unit control unit (GCU) analyzes the status parameters to determine the behavior of the person passing through the turnstile passage. When an illegal act occurs, it needs to notify the gate unit whether to take blocking action.

[0005] However, when the transmitter or receiver in the sensor assembly malfunctions, the sensor optical path may be blocked, resulting in incorrect state parameters that affect the judgment of the gate unit control device. Or, when illegal passage is detected, the rail transit operator cannot confirm whether it is caused by a sensor malfunction or a defect in the passage logic algorithm.

[0006] When a door unit experiences a fault, such as failing to detect passage behavior or failing to respond to control commands, it is often difficult to pinpoint whether the fault is due to a sensor or a control board, and which sensor is faulty. This results in a significant amount of time and effort being required for fault analysis and location during on-site repairs. Utility Model Content

[0007] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art, and to provide a door unit control board and a gate sensor group detection device. The device is connected to the sensor group and the GCU through an interface unit. The signals fed back by the sensor group and the GCU are transmitted to the control unit through the interface unit. The control unit judges the working status of the sensor group and the GCU and feeds it back to the display unit. The display unit accurately locates whether the fault is a sensor or a GCU, saving time and effort.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A gate unit control board and a gate sensor group detection device include a housing. The housing is characterized by having an interface unit, a display unit, and an operation unit. A control unit is installed inside the housing. The interface unit, display unit, and operation unit are all electrically connected to the control unit. The interface unit connects to the sensor group and the gate control unit (GCU). The display unit displays the layout and fault indicators of the sensor group. The operation unit switches the test modes of the detection device and accesses the command menu. The control unit collects signals from the sensor group and the GCU and determines their operating status. This device connects to the sensor group and the GCU via the interface unit. Signals from the sensor group and the GCU are transmitted to the control unit through the interface unit. The control unit determines the operating status of the sensor group and the GCU and feeds it back to the display unit. The display unit accurately identifies whether the fault is in the sensor or the GCU, saving time and effort.

[0010] Furthermore, the control unit includes a signal acquisition module and a communication control module. The signal acquisition module is connected to a digital filtering module and a fault analysis module. The signal acquisition module is connected to the sensor group to acquire sensor signals and transmit them to the digital filtering module. The digital filtering module filters the acquired sensor signals to determine the sensor status. The fault analysis module analyzes whether the sensor is faulty based on the sensor status and transmits the result to the display unit. The communication control module is connected to the GCU to simulate an industrial control computer sending control commands to the GCU and analyzes the GCU response signal to determine whether the GCU is faulty.

[0011] Furthermore, the control unit also includes Timer A, Timer B, and a serial port module. Timer A is used for system timing, Timer B is connected to the signal acquisition module, and the signal acquisition module acquires sensor signals through Timer B. The serial port module is connected to the signal acquisition module and the communication control module to receive sensor status data and instructions sent by the GCU to the gate unit.

[0012] Furthermore, the interface unit includes a sensor interface, a GCU interface, and a power socket. The sensor interface is used to connect the sensor group, the GCU interface is used to connect the GCU, and the power socket is used to connect the power supply.

[0013] Furthermore, the display unit includes a display screen, a status indicator light for the through-beam sensor group, and a status indicator light for the diffuse reflection sensor group. The display screen is used to display a layout diagram of the sensor group, and the status indicator lights for the through-beam sensor group and the diffuse reflection sensor group are used to display the status of the through-beam sensor and the diffuse reflection sensor, respectively.

[0014] Furthermore, when the status indicator lights for the through-beam sensor group and the diffuse reflection sensor group are green, the through-beam sensor and the diffuse reflection sensor are in normal condition; when the status indicator lights for the through-beam sensor group and the diffuse reflection sensor group are red, the through-beam sensor and the diffuse reflection sensor are in fault condition.

[0015] Furthermore, there are multiple status indicator lights for the through-beam sensor group and the diffuse reflection sensor group, each corresponding to a specific installation position of the through-beam sensor and the diffuse reflection sensor.

[0016] Furthermore, the operation unit includes an auxiliary keyboard for operating the detection device.

[0017] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0018] This invention connects the sensor group and the GCU via an interface unit. The signals fed back by the sensor group and the GCU are transmitted to the control unit through the interface unit. The control unit judges the working status of the sensor group and the GCU and feeds it back to the display unit. The display unit accurately locates whether the fault is a sensor or a GCU, saving time and effort.

[0019] In this invention, the different colors displayed by the status indicator lights of the through-beam sensor group and the diffuse reflection sensor group indicate whether a sensor has malfunctioned. When the light is green, it indicates that the sensor is in normal condition, and when it is red, it indicates that the sensor has malfunctioned. At the same time, each status indicator light of the through-beam sensor group and the diffuse reflection sensor group corresponds to one through-beam sensor and one diffuse reflection sensor. By using different colors, it is possible to clearly and accurately locate the specific sensor that has malfunctioned. Attached Figure Description

[0029] like Figure 1As shown, this utility model discloses a door unit control board and a gate sensor group detection device, including a housing 1. The housing 1 is equipped with an interface unit, a display unit, and an operation unit. A control unit is installed inside the housing 1. The interface unit, display unit, and operation unit are all electrically connected to the control unit. The interface unit includes a sensor interface 2, a GCU interface 3, and a power socket 4. The sensor interface 2 is used to connect the sensor group, the GCU interface 3 is used to connect the GCU, and the power socket 4 is used to connect the power supply. The display unit includes a display screen 5, a through-beam sensor group status indicator light 6, and a diffuse reflection sensor group status indicator light 7. The display screen 5 is used to display a sensor group layout diagram. The through-beam sensor group status indicator light 6 and the diffuse reflection sensor group status indicator light 7 are used to display the status of the through-beam sensor and the diffuse reflection sensor, respectively. When the through-beam sensor group status indicator light 6 and the diffuse reflection sensor group status indicator light 7 are green, the through-beam sensor and the diffuse reflection sensor are in normal condition. When the through-beam sensor group status indicator light 6 and the diffuse reflection sensor group status indicator light 7 are red, the through-beam sensor and the diffuse reflection sensor are in normal condition. The sensor is in a faulty state, and there are multiple status indicator lights 6 for the through-beam sensor group and 7 for the diffuse reflection sensor group, each corresponding to the installation position of the through-beam and diffuse reflection sensors. The specific sensor that has failed is identified by the different colors displayed, allowing for clear, concise, and accurate location of the faulty sensor. The operation unit includes an auxiliary keyboard 8, which is used to operate the detection device, switch test modes, and access the command menu. The control unit is used to collect signals from the sensor group and GCU and determine their operating status to identify whether the sensor group and GCU have failed. The control unit then feeds back the results to the display unit, which shows whether the failure is due to the GCU or a specific sensor. The device connects to the sensor group and GCU via an interface unit. The signals from the sensor group and GCU are transmitted to the control unit through the interface unit. The control unit determines the operating status of the sensor group and GCU and feeds back the results to the display unit, allowing for accurate location of whether the failure is due to a sensor or a GCU, saving time and effort.

[0030] In this embodiment, both the through-beam sensor group status indicator 6 and the diffuse reflection sensor group status indicator 7 are equipped with reserved indicator lights 9, which can ensure that they can be used even when the number of through-beam sensor groups and diffuse reflection sensor groups is different.

[0031] like Figures 2 to 7 As shown, the control unit includes a signal acquisition module, a communication control module, timer A (1ms), timer B (5ms), and a serial port module. Timer A is used for system timing, and timer B is connected to the signal acquisition module. The signal acquisition module acquires sensor signals through timer B. Both the signal acquisition module and the communication control module are connected to the serial port module, which is used to receive sensor status data and instructions sent by the GCU to the gate unit.

[0032] When this utility model detects a sensor group: the signal acquisition module is connected to the sensor group through sensor interface 2. The signal acquisition module acquires sensor signals in real time through timer B. The signal acquisition module is connected to a digital filtering module and a fault analysis module. The sensor signals acquired by the signal acquisition module through timer B are transmitted to the digital filtering module. The digital filtering module filters the acquired sensor signals to determine the sensor status. Subsequently, the fault analysis module analyzes whether the sensor is faulty based on the sensor status through timer A and transmits the results to the status indicator lights 6 and 7 of the through-beam sensor group and the diffuse reflection sensor group through the serial port module. When the sensor is normal, the status indicator lights 6 and 7 of the through-beam sensor group and the diffuse reflection sensor group are green. When the sensor is faulty, the status indicator lights 6 and 7 of the through-beam sensor group and the diffuse reflection sensor group are red.

[0033] In this embodiment, when the signal acquisition module acquires the sensor status, it detects whether the acquired signal is a valid signal. The valid signal is determined by the acquisition of a low-level signal that transitions to a high level after 60ms.

[0034] After acquiring a valid signal, it undergoes digital filtering to determine whether the sensor is in a light-blocking or light-transmitting state, thereby obtaining the sensor's status.

[0035] When testing the GCU, the communication control module connects to the GCU through the GCU interface 3. The testing device sends instructions to the GCU and receives its feedback through a simulated industrial control computer, thereby analyzing the GCU response signal to determine whether the GCU is faulty. Finally, the test results are transmitted to the display screen 5, which shows whether the GCU is normal or faulty.

[0036] This invention can simulate and replace the control commands issued by an industrial control computer, and effectively verify whether the gate unit control board (GCU) is working properly based on the feedback from the GCU. Simultaneously, this device can replace the GCU, connect to the sensor modules on the left and right sides of the gate, and perform branch-path positioning verification to check whether the sensors at different locations are working properly.

[0037] This invention can simultaneously connect to the GCU and sensor group, and perform testing and verification work on the GCU and sensor group at the same time. This changes the previous debugging process, where the industrial control computer or test computer could only connect to a single module for testing at a time, greatly simplifying the testing process and improving efficiency.

[0038] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
