[0038] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0039] Example 1

[0040] This embodiment provides a smart service area parking management device, such as Figure 1-2 As shown, it includes a network camera 2, a function box 8 and an energy storage box 7 arranged from top to bottom;

[0041] The outside of the function box 8 is provided with an alarm light 4 and a network speaker 5, and the inside of the function box 8 is provided with a main control board, an FPGA circuit board, a power module, a power supply circuit and a network module. The power module and the power supply circuit are respectively connected to the main control board for power supply; the alarm light 4, the network speaker 5 and the FPGA circuit board are all communicatively connected to the main control board, and the FPGA circuit board is communicatively connected to the network camera 2 through the network module;

[0042] A flame retardant layer 6 is provided between the functional box 8 and the energy storage box 7, and a flame retardant terminal is provided on the flame retardant layer 6;

[0043] The energy storage box 7 is provided with a battery, and the battery is connected to the power supply circuit via a flame-retardant terminal.

[0044] Preferably, the battery is a lithium battery.

[0045] Preferably, magnesium hydroxide cement board, cement board or fireproof gypsum board is provided in the flame retardant layer 6. The flame retardant layer 6 and the flame retardant terminal can prevent the battery from catching fire and damaging the main control board and FPGA circuit board inside the function box 8.

[0046] Furthermore, the network camera 2 is fixed to the top of the function box 8 through an adjustable bracket, wherein the adjustable bracket includes a support plate hinged at one end to the top of the function box 8 and a hydraulic support arranged at the bottom of the other end of the support plate, and the driving end of the hydraulic support is arranged inside the function box 8 and is communicatively connected to the main control board.

[0047] Specifically, the shooting angle of the network camera 2 is adjusted by adjusting the height of the hydraulic support of the adjustable bracket, thereby increasing the probability of detecting abnormal behavior.

[0048] Specifically, the smart service area parking management device is set in each parking space. Specifically, when a vehicle is parked in a parking space, the smart service area parking management device starts to work; wherein the FPGA circuit board of the parking management device has a built-in parking lot abnormal behavior recognition algorithm, and the network camera 2 is used to capture the image of the parking space area and send the image to the FPGA circuit board through the network module. The FPGA circuit board determines whether an abnormal event occurs based on the built-in parking lot abnormal behavior recognition algorithm.

[0049] Specifically, the FPGA circuit board uses the PGL22G-6CMBG324 chip, which has a built-in parking lot abnormal behavior recognition algorithm. This algorithm uses existing parking lot abnormal behavior recognition algorithms, such as the parking lot abnormal event detection method proposed in 202210838170.1 or the parking lot abnormal behavior recognition based on deep learning proposed by Hu Jun of Xihua University, to detect abnormal pedestrian behavior. Since this is not the focus of this application, it will not be described in detail here.

[0050] Furthermore, heat dissipation holes are provided on the function box 8 , and a heat dissipation fan is provided inside the function box 8 corresponding to the heat dissipation holes, and the heat dissipation fan is connected to the main control board.

[0051] In one embodiment, the main control board is provided with a main control chip, a fan control circuit, a network audio control circuit and an alarm light 4 control circuit.

[0052] like Figure 3 As shown, the main control chip is the STM32F407VET6 chip, which is a high-performance microcontroller based on the ARM Cortex-M4 core. It has rich peripherals and functions and is widely used in the development of various embedded systems.

[0053] like Figure 4 As shown, the fan control circuit includes a magnetic latching relay FH44L-1AT-L2-DC3V, wherein the pin 1 of the magnetic latching relay is connected to the RELAY0 signal of the STM32F407VET6 chip through a first switch circuit, and the pin 4 of the magnetic latching relay is connected to the RELAY1 signal of the STM32F407VET6 chip through a second switch circuit; the pin 2 of the magnetic latching relay is connected to the cooling fan, and the pin 3 of the magnetic latching relay is connected to the power supply; the pin 5 of the magnetic latching relay is connected to the pull-up power supply through a pull-up resistor. Specifically, when the RELAY0 signal of the STM32F407VET6 chip is at a low level and the RELAY1 signal is at a high level, the energized coil between pins 1 and 5 of the magnetic latching relay FH44L-1AT-L2-DC3V is de-energized, and the energized coil between pins 4 and 5 is energized, and the magnetic latching relay FH44L-1AT-L2-DC3V supplies power to the cooling fan; when the RELAY0 signal of the STM32F407VET6 chip is at a high level and the RELAY1 signal is at a low level, the energized coil between pins 1 and 5 of the magnetic latching relay FH44L-1AT-L2-DC3V is energized, and the energized coil between pins 4 and 5 is de-energized, and the magnetic latching relay FH44L-1AT-L2-DC3V stops supplying power to the cooling fan.

[0054] like Figure 5 As shown, the network audio control circuit includes an Ethernet transceiver LANB720A-CP-TR and an RJ45 network connector HY971105AE. The Ethernet transceiver LANB720A-CP-TR integrates PHY functions, can support Gigabit Ethernet communication, and has good transmission performance and stability, which can meet the needs of high-speed network communication.

[0055] The RXD and TXD pins of the Ethernet transceiver LANB720A-CP-TR are connected to the RXD and TXD ports of the STM32F407VET6 chip to receive the alarm voice data, and are connected to the RJ45 network connector HY971105AE through the RXP, RXN, TXP, and TXN pins to send the alarm voice data to the network speaker 5.

[0056] like Figure 6As shown, the control circuit for the warning light 4 includes a photocoupler PC817. The JDQ_CTR signal from the STM32F407VET6 chip is connected to the anode of the photocoupler PC817 via a third switch circuit consisting of S9012 2T1, R39, R40, R41, and R44. The collector of the photocoupler PC817 is connected to the warning light 4 via a fourth switch circuit consisting of an IRF5305S, resistors R37 and R42, and VCC12 and 12V. Specifically, when the JDQ_CTR signal from the STM32F407VET6 chip is low, the S9012 2T1 is turned on, the light-emitting diode of the photocoupler PC817 emits light, and power is supplied to the warning light 4 via the fourth switch circuit. When the JDQ_CTR signal of the STM32F407VET6 chip is at a high level, the S9012 2T1 is cut off, the light emitting diode of the photoelectric coupler PC817 does not emit light, and power is not supplied to the warning light 4 through the fourth switch circuit.

[0057] like Figure 7 The power module schematic diagram shows the circuitry of the power supply module, which includes a circuit board power inlet protection circuit, a power supply switching circuit, and a lithium battery charging circuit. The circuit board power inlet protection circuit consists of a HAW15-220S05E2 power module (AC220V to DC5V converter), a TVS (P6SMB6.8CA), a fuse F1, a BTSA-LS-6 (Taiwan) switch, and a 2A synchronous step-down SY8089A1AAC DC-DC power supply chip.

[0058] The lithium battery charging circuit includes a TP4056 lithium battery charging chip. The TP4056 lithium battery charging chip transmits charging status to the STM32F407VET6 chip via the CHRG and STDBY pins for display. Specifically, the TP4056 begins charging the battery when the input voltage exceeds the UVLO detection threshold and the chip enable input CE is high. The charging cycle ends when the lithium battery's charging current decreases to the end-of-charge threshold.

[0059] The power supply switching circuit includes switch tubes Q7, Q8, Q9 and switch tubes Q4-Q6, Q15, Q16. An ADC value near (2.5 / 3.3)*4095 indicates external 220V power supply; an ADC value below (2.5 / 3.3)*4095 indicates battery power supply.

[0060] like Figure 8 FIG2 is a schematic diagram of the power supply circuit, which includes a switching regulator LMR14020SDDAR for operating when powered by a battery.

[0061] Example 2

[0062] The difference between this embodiment and embodiment 1 is that: Figure 9 As shown, an infrared probe 3 is provided on the outside of the function box 8, and the infrared probe 3 is in communication connection with the main control board for performing motion detection and triggering the main control board to start the FPGA circuit board when a motion event is detected.

[0063] The infrared probe 3 is used to detect motion events, such as whether there is movement of a vehicle or person; when motion is detected, the infrared probe 3 sends a trigger signal to the main control board. After receiving the trigger signal, the main control board starts the FPGA circuit board. The FPGA circuit board works and receives the images captured by the network camera 2 to identify abnormal behavior. It should be noted that it can be seen that the setting of the infrared probe 3 allows the infrared probe 3 set on the outside of the function box 8 to trigger the main control board to start the FPGA circuit board when a motion event is detected, and does not trigger the start of the FPGA circuit board when no motion event is detected. The FPGA circuit board is in standby mode, thereby achieving a low-carbon and energy-saving effect.

[0064] Example 3

[0065] The difference between this embodiment and embodiment 2 is that: Figure 10 As shown, a solar cell panel 1 is further provided above the network camera 2 , and the solar cell panel 1 is fixed to the top of the function box 8 through a support, and is connected to the power supply module inside the function box 8 for power supply.

[0066] Specifically, the solar panel 1 can provide shade and charge the battery or directly supply power to the main control board on sunny days, and can also prevent rainwater from seeping into the network camera 2 and the function box 8 on rainy days.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
