Figure 1 As shown, the barrier device may include: a power management module 10, a barrier control board 20 including a barrier control module 21 and a main control module 22, a ground sensor signal sensing module 30, a Wiegand reading module 40, and an RJ45 network communication module 60 connected to the server via a network isolator J1 50;
[0036] Among them, the RJ45 network communication module 60 is connected to the main control module 22 via the TTL serial port;
[0037] One end of the gate control module 21 is connected to the main control module 22 via the GPIO interface, and the other end of the gate control module 21 is connected to the external gate motor board via the first external port CN1;

[0041] The main control module may be a microprocessor supported by a CH32F103C8T6 chip.
[0042] (1) The core component of the power management module can be the MP1584 chip.
[0043] To protect circuit safety, the power interface of the power management module 10 is connected to the second external port CN2 via a resettable fuse F1. A TVS protection diode D3 is connected in parallel between the positive and negative terminals of the power interface, effectively protecting downstream circuits in the event of overcurrent or overvoltage in the external power supply. A 0Ω resistor is connected in series between the power interface of the power management module 10 and the power interface of the RJ45 network communication module. External port CN2 is connected to an external DC power supply (DC 10V-16V).
[0044] The power management module 10 may include a first chip, such as an MP1584 chip, and a second chip connected to the first chip, such as an LM1117IMPX3-3 chip;
[0045] The first chip is used to stabilize the input voltage connected to the second external port CN2 to a first voltage value (e.g., 5V) via a resettable fuse F1. This means that the power interface of the power management module 10 serves as the interface of the first chip. The first voltage value is then input to the second chip, which then steps down the first voltage value to a second voltage value (e.g., 3.3V) to power other modules. This means that the power interface of the power management module 10 serves as the interface of the second chip. Furthermore, to improve the circuit's anti-interference capabilities, a parallel resistor is used to isolate the external DC power supply from the GND pin of the first chip.
[0046] like Figure 2As shown, taking the first chip as the MP1584 chip as an example, the circuit connection structure between the second external port CN2 connected to the external DC power supply and the first chip may include: the VIN interface of the MP1584 chip is connected to the port 2 of the second external port CN2 through the self-resettable fuse F1; the GND interface of the MP1584 chip is grounded; The FREQ interface of the MP1584 chip is grounded through resistor R20.

[0048] (2) The gate control module 21 may include an enabling circuit 211, a driving circuit 212, and a relay 213;
[0049] The enabling circuit 211 is connected to one end of the driver circuit 212, the other end of which is connected to one end of the relay 213. The other end of the relay 213 is connected to the external gate motor board via the first external port CN1. The core component of the gate control module is the HKV6-DC5V-SG chip.
[0050] The main control module 22 is connected to the drive circuit via GPIO, and then drives the relays respectively. The gate motor board is connected to the first external port CN1 through an electronic wire; using field effect transistors as the drive circuit can not only increase the control speed of the switch, but also improve the stability and reliability of the control.
[0051] It should be noted that if two barriers are configured, two barrier control modules are required.

[0053] The external Wiegand reader is connected to the first external interface CN1 to receive the Wiegand signal. The Wiegand signal passes through the signal line and the conversion circuit converts the Wiegand 5V level signal into a 3.3 level signal. The main control module 22 is connected to the conversion circuit via GPIO;
[0054] A diode may be connected in series between the conversion circuit of the Wiegand reading module and the first external interface CN1 to prevent abnormal external voltage signals from being input and protect the subsequent conversion circuit.
[0055] In order to further improve the signal quality and reduce disturbances, an RC parallel circuit and a parallel reverse diode are added to the connection path between the conversion circuit and the diode to stabilize the voltage and current of the optocoupler optical signal circuit.
[0056] Further, combined Figure 1 The barrier gate device may further include: a clock operation module 70; a storage module 80; a 485 communication module 90, a barrier gate operation temperature and humidity sensing module 100, a barrier gate drop limit sensing module 110 and a function configuration module 120.
[0057] The data interface of the clock operation module 70 is connected to the main control module 22 via the I2C bus. The core component of the clock operation module may be a CH32F103C8T6 chip.

[0059] The main control module 22 is connected to the 485 communication module 90 via a TTL serial port, and the 485 communication module 90 is connected to an external 485 device via a first external port CN1. The external 485 device may be a display screen, a voice broadcast device, etc. The core component of the external 485 device may be SP485EEN-L.
[0060] The gate operation temperature and humidity sensing module 100 is set in the gate chassis and connected to the main control module 22 through the I2C interface. The gate operation temperature and humidity sensing module can be a temperature and humidity sensor, such as an SHT40 chip.
[0061] One end of the barrier gate drop limit sensing module 110 receives the barrier gate limit electrical signal through the first external port CN1, and the other end of the barrier gate drop limit sensing module 110 is connected to the main control module 22 through the GPIO interface. Among them, the barrier gate drop limit sensing module can include the core component TLP185 chip, resistors R51-R54, capacitor C25 and diode D14.

The other end of the resistor R51, the other end of the capacitor C25 and the other end of the diode D14 intersect, and the intersection is connected to port 2 of the first external port CN1; one end of the resistor R52 is connected to one end of the diode D14, and the other end of R52 is connected to pin 1 of the TLP185 chip, and the other end of the diode D14 is connected to pin 3 of the TLP185 chip. Pin 6 of the TLP185 chip is connected to one end of the resistor R53, and the other end of the resistor R53 is connected to a 3.3V voltage; pin 6 of the TLP185 chip is also connected to one end of the resistor R54, and the other end of the resistor R54 is connected to the main control module through the GPIO interface; pin 4 of the TLP185 chip is grounded.
[0062] The function configuration module 120 is connected to the main control module 22 via the first external port CN1 and is used to determine a function control instruction to be sent to the main control module 22 according to the triggered function selection button, so that the main control module 22 controls the corresponding module function according to the function control instruction.
[0063] The function configuration module 120 may include function selection buttons for controlling multiple modules, such as 6 buttons: K1-K6, wherein K1 is turned on to instruct the main control module to control the ground sensing signal perception module to set the ground sensing mode, K2 is turned on to instruct the main control module to control the clock operation module to modify the original duration to twice the original duration, K3 is turned on to instruct the main control module to control the clock operation module to modify the original duration to three times the original duration, wherein, if both K2 and K3 are turned on, the main control module is instructed to control the clock operation module to modify the original duration to six times the original duration, K4 is turned on to instruct the main control module to control the external voice broadcast connected to the 485 communication module to broadcast detailed voice when the validity period of the whitelist in the storage module expires / expires, K5 is turned on to instruct the main control module to change the communication direction of the 485 communication module, and K6 is turned on to instruct the main control module to control the external display screen connected to the 485 communication module to display the entry / exit instructions, such as the entrance displaying welcome home / the exit displaying safe journey.

All binary values consisting of 1 in the function configuration module are identified as a function control instruction and sent to the main control module, thereby expanding the number of control instructions. For example, in a system with six buttons, 000001 is a function control instruction with a value of 1, which can be used to control the communication direction of the 485 communication module; 000011 is a function control instruction with a value of 2, which can be used to control the display of entry / exit indicators on an external display connected to the 485 communication module; ..., 000101 is a function control instruction with a value of 5, which can be used to control the ground sensing signal perception module to set the ground sensing mode, ...
[0065] In some embodiments, the barrier device may further include a radar and a radar warning light;
[0066] The radar is installed alongside the gate pole outside the gate chassis, which is enclosed by the gate control panel. The radar has a radar indicator light. The radar connects to the main control module via the first external port CN1. When the gate is open, if the radar detects a target object within the set scanning area, the indicator light on the radar lights up and transmits this detection information to the main control module, which then triggers the gate control module to prevent the gate pole from falling.
[0067] Also, during the gate bar's descent, if an object suddenly breaks into the scanning area set by the radar, the radar warning light will light up, and the radar will send the detection information to the main control module. At this time, the main control module will trigger the gate control module to control the gate bar to stop falling and automatically rise until it is fully raised. After the target object leaves, the radar warning light will go out and the gate bar will automatically fall.
