Obviously, the described embodiments are only some of the embodiments of the present scheme, not all. Based on the embodiments in the present scheme, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present scheme.

[0033] The implementation of the present disclosure is described in detail below in combination with specific drawings:

[0034] Figure 1 is a structural schematic diagram of a device centralized control system provided by an embodiment of the present disclosure. Referring to Figure 1 , the device centralized control system comprises:

[0035] The first camera, the controller, the timer, the weighing device and the vehicle detection device;

[0036] The controller comprises a serial module, a central computing module, an input / output module and a peripheral power supply module;

[0037] The first camera, the timer, the weighing device and the vehicle detection device are connected with the input / output module, the first camera is used for monitoring the lane information of the highway toll station, the serial module, the input / output module and the peripheral power supply module are connected with the central computing module;

[0038] The vehicle detection device comprises an ultrasonic ranging circuit, an infrared detection circuit and an OR gate circuit; the input end of the OR gate circuit is connected with the output end of the ultrasonic ranging circuit and the output end of the infrared detection circuit respectively, and the output end of the OR gate circuit is connected with the input / output module;

[0039] The serial module is used for connecting with the intelligent device in the lane.

[0040] In the embodiment, the vehicle detection device comprises an ultrasonic ranging circuit, an infrared detection circuit and an OR gate circuit, the ultrasonic ranging circuit and the infrared detection circuit can both detect the vehicle, and the accuracy of vehicle detection can be ensured by combining the OR gate circuit.

[0041] The working principle of the ultrasonic ranging circuit for detecting the vehicle is as follows: the ultrasonic ranging circuit comprises an ultrasonic transmitter, a receiver and a comparator. The ultrasonic transmitter emits ultrasonic waves in a certain direction, and starts timing at the same time of emission; the ultrasonic waves propagate in the air and return immediately when encountering a vehicle, and the receiver stops timing immediately after receiving the reflected waves. According to the time recorded by the timer, the distance from the emission point to the obstacle can be obtained. The distance signal is input into the comparator to compare with the reference signal, and a high-level signal is output when the distance is greater than the reference signal, so that it can be judged that there is a vehicle.

[0042] The infrared detection circuit is based on the infrared sensing ranging principle. The infrared detection circuit comprises a plurality of infrared sensors, and each infrared sensor comprises a pair of infrared emitter tubes and an infrared receiver tube. The infrared emitter tubes emit infrared light beams at a certain angle, and the light beams are reflected back when encountering a vehicle, and the reflected infrared light is detected by the infrared receiver tube. When the vehicle does not enter the detection area, the infrared receiver tube receives less light; when the vehicle enters the detection area, the infrared receiver tube receives more light due to the reflection of the vehicle surface, and the infrared signal strength increases. When the infrared signal strength is greater than a preset threshold, a high-level signal is output, so that it can be judged that there is a vehicle.

[0043] After the controller receives the high-level signal sent by the vehicle detection module, the weighing module is started for weighing, and the first camera device is started for recording at the same time. When the controller receives the signal sent by the weighing module, the timer is started for timing. After the timing is completed, the first camera device enters the sleep mode.

[0044] In the embodiment, the first camera device includes a camera body, a lens, an image sensor, a processor, a storage unit, a communication interface and the like, and is used for collecting and storing the photographed images. The controller mainly consists of a serial module, a central computing module, an input / output module and a peripheral power supply module. The modules are connected with each other through an internal bus to form a complete controller. The serial module includes a serial chip and an interface circuit, and is used for serial communication with other intelligent devices. The central computing module adopts a microprocessor or a single-chip microcomputer, and is responsible for processing data from the input / output module and executing control logic. The input / output module includes an input interface and an output interface, and is used for data exchange with external devices (such as the camera device, the timer, the weighing device, the lane information display screen, the signal lamp, the barrier machine and the like). The peripheral power supply module provides stable power supply for the controller and the peripherals connected thereto.

[0045] The weighing device includes a weighing sensor, a signal processing circuit, a display and a communication interface. The weighing sensor can convert the gravity of the vehicle into an electrical signal. After the signal is amplified and filtered by the signal processing circuit, the display can convert the processed signal into a digital signal and display it on the display. The communication interface can be used for data transmission with the input / output module.

[0046] As can be seen from the above, the embodiment of the disclosure realizes comprehensive monitoring and control of the lane information of the highway toll station through a highly integrated design. The first camera device is used to accurately capture the lane dynamics, and the timer, the weighing device and the vehicle detection device are combined for multiple verifications to ensure the accuracy and integrity of the vehicle information. The ultrasonic ranging and infrared detection in the vehicle detection device are double-protected, and the or gate circuit is intelligently fused to improve the reliability of vehicle recognition. At the same time, as the core, the controller is seamlessly connected with the lane intelligent device through the serial module to realize real-time interaction of data and remote control of the device, which not only improves the work efficiency but also reduces the operation and maintenance cost, and exhibits a high level of intelligence and automation.

[0047] In one embodiment of the disclosure, referring to Figure 2 , the infrared detection circuit includes a plurality of infrared sensors, a plurality of infrared detection branches, a sampling circuit and a comparison circuit.

[0048] The input ends of the plurality of infrared detection branches are respectively connected with the output ends of the plurality of infrared sensors, the output ends of the plurality of infrared detection branches are all connected to the first end of the sampling circuit, and the second end of the sampling circuit is grounded.

[0049] The first end of the sampling circuit is also connected to a first input end of a comparison circuit, a second input end of the comparison circuit is connected to a reference voltage, and an output end of the comparison circuit is connected to an input end of the OR gate circuit.

[0050] In the embodiment, a plurality of infrared sensors are arranged at positions around the vehicle, each infrared sensor outputs a high-level signal when detecting the vehicle, and the infrared detection branch detects current. If the infrared sensor does not detect the vehicle, a low-level signal is output, and the infrared detection branch does not detect current. The plurality of infrared detection branches converge current into the sampling circuit. The sampling circuit can be a sampling resistor, and the greater the current flowing through the resistor, the greater the voltage across the resistor. In the actual process of detecting the vehicle by using the infrared detection circuit, when the number of infrared sensors outputting high-level signals is greater than a predetermined number, the current converging into the sampling circuit is greater than a preset current, the voltage across the sampling resistor in the sampling circuit is greater than a reference voltage, the comparison circuit outputs a high-level signal, and it is indicated that the vehicle is detected.

[0051] As can be seen from the above, the embodiment can accurately detect whether the vehicle enters the weighing area by using the infrared detection circuit. When the vehicle is detected to enter the weighing area, the weighing device and the lane information display screen are started to work, and the congestion of a large number of vehicles at the highway intersection is avoided to affect the traffic.

[0052] In an embodiment of the present disclosure, the controller further comprises a network port module and a multimedia interface module;

[0053] The network port module and the multimedia interface module are connected to the central computing module. The multimedia interface module comprises an audio interface and a video interface;

[0054] The audio interface and the video interface are connected to the central computing module.

[0055] In the embodiment, the network port module is mainly used to realize the connection and communication between the controller and external network equipment. The network port module can be a GE network port, which can receive data packets from the external network, preliminarily process and analyze the data packets, and then send the processed data packets to the central computing module for further analysis and processing. At the same time, the network port module can also receive control instructions and data sent by the central computing module, encapsulate the data into data packets conforming to the network protocol, and then send the data packets to the external network, so as to realize the data interaction and communication between the controller and the external network equipment.

[0056] The multimedia interface module mainly comprises an audio interface and a video interface. The controller can control the loudspeaker on the lane to play the pre-recorded voice prompt information through the audio interface. The video interface module can be HDMI, which can obtain the high-definition video data collected by the first camera device.

[0057] From the above, the controller of the embodiment realizes convenient communication with external network devices and interaction of audio and video data by adding a network port module and a multimedia interface module, enhances the functional diversity of the controller, and provides strong support for applications in the field of intelligent transportation and the like.

[0058] In an embodiment of the present disclosure, the controller further comprises a fiber interface module and a gateway switch;

[0059] The gateway switch is connected with the fiber interface module and the central computing module respectively.

[0060] In the embodiment, the gateway switch serves as the core device of the network, is responsible for connecting the fiber interface module and the central computing module, and realizes forwarding and routing of data packets. It can transmit data between different networks, and ensures correct transmission of data and stability of the network. The fiber interface module is used to realize connection and data transmission between the controller and fiber network devices. The fiber interface module provides high-speed and long-distance data communication capability, and is suitable for application scenarios such as highway toll station, which requires large bandwidth and low delay.

[0061] From the above, by integrating the fiber interface module and the gateway switch, the controller realizes high-speed and stable connection with the fiber network device, effectively improves the data transmission bandwidth and reduces the communication delay, and is especially suitable for scenarios such as highway toll station, which requires efficient data interaction, and ensures reliability and real-time performance of network communication.

[0062] In an embodiment of the present disclosure, the controller further comprises a protocol processing module, a data storage module, a clock module, a temperature monitoring module, and a heat dissipation module.

[0063] The temperature monitoring module and the heat dissipation module are connected with the central computing module.

[0064] The input and output module is connected with the central computing module through the protocol processing module, and the data storage module and the clock module are connected with the central computing module.

[0065] In the embodiment, the protocol processing module can process the communication protocol between the input and output module and the central computing module. It can encapsulate and decapsulate the data sent by the input and output module according to the predetermined protocol, and ensure correct transmission and analysis of the data. The protocol processing module is implemented using hardware technologies such as application-specific integrated circuit (ASIC) and field programmable gate array (FPGA). The data storage module is used to store data and programs required for operation of the controller. The clock module provides accurate time information for the controller. It ensures time synchronization between various modules inside the controller, and time consistency between the controller and external devices.

[0066] The temperature monitoring module is used for monitoring the temperature condition of the controller in real time, and sending the temperature information to the central computing module, so that the central computing module starts the heat dissipation module in time to dissipate heat.

[0067] From the above, the controller realizes efficient data communication, stable time synchronization, real-time temperature monitoring and intelligent heat dissipation management through the integration of protocol processing, data storage, clock, temperature monitoring and heat dissipation module. The use of hardware technologies such as ASIC and FPGA improves the protocol processing capability, ensures the accuracy of data transmission and the reliability of system operation, and effectively prolongs the service life of the controller.

[0068] In an embodiment of the present disclosure, the peripheral power supply module further comprises an overvoltage protection circuit and a leakage protection circuit.

[0069] In this embodiment, the overvoltage protection circuit is a circuit for monitoring and controlling the output voltage of the power supply. The overvoltage protection circuit is composed of a voltage detection unit, a comparison unit and a protection execution unit. The voltage detection unit is responsible for monitoring the output voltage of the power supply in real time, and converting it into an electrical signal proportional to the voltage size. The comparison unit compares the electrical signal sent by the voltage detection unit with the pre-set overvoltage threshold signal. When the output voltage of the power supply is normal, the detection signal is less than the overvoltage threshold signal, and the comparison unit outputs a low-level signal, and the protection execution unit is in standby state and does not interfere with the power output. Once the output voltage of the power supply exceeds the set overvoltage threshold, the detection signal is greater than the overvoltage threshold signal, and the comparison unit immediately outputs a high-level signal to trigger the protection execution unit to act. The protection execution unit quickly takes appropriate protective measures according to the received trigger signal, such as cutting off the power output circuit, isolating the external device from the high voltage power supply, or adjusting the output voltage of the power supply to restore it to the normal range, so as to avoid damage to the external device caused by high voltage.

[0070] The leakage protection circuit is a circuit for detecting whether there is a leakage phenomenon in the circuit, and quickly cutting off the circuit when leakage occurs, to protect personal safety and normal operation of the equipment. The leakage protection circuit works based on Kirchhoff's current law. Normally, the current of the phase line and the zero line is equal in size and opposite in direction, and there is no induced current at the secondary side of the zero sequence current transformer. Once leakage occurs, the current vector sum of the two is not zero, and the induced current is generated at the secondary side of the transformer, triggering the protection device to cut off the circuit.

[0071] From the above, the overvoltage protection circuit and the leakage protection circuit have significant beneficial effects on ensuring equipment safety, improving system stability, prolonging equipment life and preventing electrical fires, etc.

[0072] In one embodiment of the present disclosure, the serial port module supports multiple serial communication protocols, including RS232, RS485 and USB serial communication protocols.

[0073] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
