Abstract
Description
Technical Field
[0001] This utility model relates to the field of millimeter-wave radar technology, specifically a gate control device based on gate radar. Background Technology
[0002] A barrier gate, also known as a vehicle barrier, is widely used at highway toll booths, residential areas, industrial parks, shopping malls, and other entrances to manage vehicle access. Due to the ease of installation and high accuracy of millimeter-wave radar, it is widely used for controlling the gate's arm. When the millimeter-wave radar detects a target, it outputs a signal to the gate control panel to raise the arm; when no target is detected in the area, the arm lowers.
[0003] Currently, millimeter-wave radar has some limitations in controlling turnstiles. When a vehicle is in the detection area and the gate is raised, if the millimeter-wave radar power supply is abnormal, the gate gate will fall down, causing a car-smashing accident. This invention can output a gate-raising signal when the radar power supply is abnormal, thus solving the car-smashing accident caused by the radar power supply abnormality. Utility Model Content
[0004] The purpose of this invention is to provide a gate control device based on a barrier gate radar to solve the problem of automatic gate lowering when the power supply of the existing barrier gate radar is abnormal.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a gate control device based on a barrier gate radar, comprising a millimeter-wave radar, a gate control module, and a gate arm. The millimeter-wave radar is connected to the gate control module, and the gate control module is connected to the gate arm. The millimeter-wave radar includes a millimeter-wave main control processing unit, a relay module A, and a relay module B. The millimeter-wave main control processing unit is connected to relay module A, and the millimeter-wave main control processing unit controls the conduction of relay module A. Relay module A and relay module B are jointly connected to the gate control module. Relay module B is not conducting when the millimeter-wave radar is powered on, and conducts when the millimeter-wave radar is powered off, for outputting signals.
[0006] As a further improvement to the above technical solution:
[0007] The relay module A includes an eight-pin main relay, resistors R1 and R2, and transistor Q3. One end of resistor R1 is connected to the millimeter-wave main control processing unit, and the other end of resistor R1 is connected to one end of resistor R2 and the base of transistor Q3. The other end of resistor R2 and the emitter of transistor Q3 are both grounded. The collector of transistor Q3 is connected to pin 8 of the eight-pin main relay. Pin 1 of the eight-pin main relay is connected to the power supply Vcc, and pins 5 and 6 of the eight-pin main relay are connected to the gate control module. When the radar is powered on, the millimeter-wave main control processing unit outputs a high level through GPIO_0, which conducts pins 5 and 6 of the eight-pin main relay, and the gate control module receives the gate raising signal. When the millimeter-wave main control processing unit outputs a low level through GPIO_0, which de-conducts pins 5 and 6 of the eight-pin main relay, and the gate control module controls the gate arm to lower.
[0008] The relay module B includes an 8-pin relay, with pin 8 grounded, pin 1 connected to power supply Vcc, and pins 6 and 7 connected to the gate control module.
[0009] Pin 7 of the secondary eight-pin relay is connected to pin 5 of the primary eight-pin relay, and pin 6 of the secondary eight-pin relay is connected to pin 6 of the primary eight-pin relay. When the radar is powered on, pins 6 and 7 of the secondary eight-pin relay are not conducting, and the radar controls the gate through the primary eight-pin relay. When the radar is powered off, pins 6 and 7 of the secondary eight-pin relay are conducting, and the radar outputs a gate-raising signal.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] like Figure 1 and Figure 2As shown, the gate control device based on a barrier gate radar in this embodiment includes a millimeter-wave radar 1, a gate control module 2, and a gate arm 3. The millimeter-wave radar 1 is connected to the gate control module 2, and the gate control module 2 is connected to the gate arm 3. The millimeter-wave radar includes a millimeter-wave main control processing unit 101, a relay module A102, and a relay module B103. The millimeter-wave main control processing unit 101 is connected to the relay module A102 and controls the conduction of the relay module A102. The relay modules A102 and B103 are both connected to the gate control module 2. The relay module B103 is not conducting when the millimeter-wave radar 1 is powered on and is conducting when the millimeter-wave radar 1 is powered off. When the millimeter-wave radar 1 is powered on, Vcc is powered on; when it is powered off, Vcc is powered off.
[0022] Relay module A102 includes a main eight-pin relay, resistors R1 and R2, and transistor Q3. Relay module B103 includes a secondary eight-pin relay. Both the main and secondary eight-pin relays contain power supply pins 1 and 8, and signal pins 2, 3, 4, 5, 6, and 7. The relays operate as follows: when the relay is powered normally, signal pins 5 and 6 are connected; when the relay is powered abnormally, signal pins 6 and 7 are connected. When there is a signal output, the gate control module 2 controls the gate arm 3 to remain in the raised state; when there is no signal output, the gate arm 3 is lowered.
[0023] like Figure 3 As shown, one end of resistor R1 is connected to the millimeter-wave main control processing unit 101, and the other end of resistor R1 is connected to one end of resistor R2 and the base of transistor Q3. The other end of resistor R2 and the emitter of transistor Q3 are both grounded. The collector of transistor Q3 is connected to pin 8 of the main 8-pin relay. Pin 1 of the main 8-pin relay is connected to the power supply Vcc, and pins 5 and 6 of the main 8-pin relay are connected to the gate control module 2. Pin 7 of the secondary 8-pin relay is connected to pin 5 of the main 8-pin relay, and pin 6 of the secondary 8-pin relay is connected to pin 6 of the main 8-pin relay. Pin 8 of the secondary 8-pin relay is grounded, and pins 6 and 7 of the secondary 8-pin relay are connected to the gate control module 2. When the radar is powered on, pins 6 and 7 of the secondary 8-pin relay are not conducting; when the radar is powered off, pins 6 and 7 of the secondary 8-pin relay are conducting.
[0024] When the radar is powered on, the millimeter-wave main control processing unit 101 outputs a high level through GPIO_0, controlling the conduction of pin 3' (collector) and pin 1' (emitter) of transistor Q3, grounding pin 8 of relay module A. The power supply pins 1 and 8 of relay module A form a circuit, ensuring normal power supply to the main eight-pin relay. Pins 5 and 6 of the main eight-pin relay are then conducting, and the gate control module 2 receives the gate arm raising signal. When the millimeter-wave main control processing unit 101 outputs a low level through GPIO_0, pins 3' (collector) and pin 1' (emitter) of transistor Q3 are not conducting, disconnecting pin 8 of relay module A from ground. The main eight-pin relay experiences a power supply failure, and pins 5 and 6 of the main eight-pin relay are not conducting, resulting in no signal output. The gate control module 2 then controls the gate arm 3 to lower.
[0025] like Figure 4 As shown, pin 1 of the secondary eight-pin relay is connected to the power supply Vcc, and pin 8 is grounded. When the radar is powered on, the switch of the secondary eight-pin relay is switched to pin 5, making pins 6 and 7 non-conductive. The radar controls the gate through the main eight-pin relay. When the radar experiences an abnormal power outage, the switch of the secondary eight-pin relay is switched to pin 7, making pins 6 and 7 of the secondary eight-pin relay conductive, and the radar outputs a gate-raising signal.
[0026] This invention employs a dual control mechanism using relay modules A and B to ensure the turnstile operates safely according to predetermined logic under both normal radar operation and abnormal power outage conditions. When the radar loses power, the auxiliary eight-pin relay automatically switches its conducting state to ensure the turnstile arm remains open, preventing accidents caused by sudden power outages that could trap people in the turnstile and improving system safety.
[0027] Through the above design, the gate control device provided in this embodiment not only ensures the convenience and safety of pedestrian passage, but also improves the intelligence and reliability of the gate system, making it suitable for widespread application in various occasions requiring automatic gate control.
[0028] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
