Figure 1

[0032] Embodiments, such as Figure 1 The present application provides an Internet of Things tunnel section controller combined with digital microwave radar, which comprises:

[0033] The radar module 11 is used to non-contact acquisition of traffic flow information.

[0034] Specifically, the radar detection module is the core of the Internet of Things tunnel section controller to realize accurate traffic flow perception (i.e. vehicle perception), and can realize all-weather, non-contact traffic flow information acquisition.

[0035] ​In some embodiments, the radar module 11 comprises a digital microwave radar unit and a communication interface unit, wherein the digital microwave radar unit adopts a 24GHz digital microwave radar.

[0036] Specifically, the digital microwave radar unit of the radar module 11 actively emits 24GHz frequency band microwave signals in a non-contact manner and receives target reflection echoes, and through a Doppler frequency shift and phase difference analysis algorithm, traffic flow information such as vehicle position, speed, driving direction and lane occupation state is extracted in real time. The detection process is not affected by road deformation, water accumulation, dust accumulation or light illumination, and can work continuously in a wide temperature range of -40°C to +85°C and a longitudinal range of 0 to 200 meters.

[0037] Optionally, the digital microwave radar unit can combine the beamforming technology to identify the vehicle direction and lane ownership of 1 to 4 lanes. For example, when the radar is installed on the side wall of the tunnel at a height of 2 meters and an inclination angle of 15°, its main beam can cover all 3 lanes within 120 meters in front, and after detecting the vehicle, it outputs the structured information such as target vehicle speed 80km / h, distance from radar 85 meters, occupation of the second lane, eastward driving, etc. in the form of a hexadecimal data frame, providing the original basis for subsequent light adjustment decisions.

[0038] Preferably, the module also supports five sensitivity adjustments, which can optimize the detection range through software configuration at the tunnel curve or different section sizes, avoiding signal crosstalk in adjacent intervals.

[0039] Preferably, the installation angle of the digital microwave radar unit is 5° to 45°, which can adapt to different tunnel section sizes, curvatures and traffic observation requirements. By adjusting the angle, the detection area can cover the target lane.

[0040] The control module 12 is used to perform logical discrimination and generate control instructions according to the traffic flow information obtained by the radar module 11.

[0041] Specifically, the control module 12 is an embedded computing core integrated with a main MCU unit and a multi-protocol communication interface unit, wherein the main MCU unit is used to execute traffic flow logical discrimination algorithm and generate digital control instructions, and the communication interface unit is used to realize communication connection with other modules.

[0042] In some embodiments, the control module 12 comprises a main MCU unit and a communication interface unit, wherein:

[0043] The control module 12 is connected with the radar module 11 through an RS485 interface, and is used for periodically receiving the traffic flow information; the control module 12 is connected with the radio frequency communication module through an SPI interface, and is used for realizing the issuing of the control instruction and the reporting of the state information; the control module 12 is connected with the data storage module 13 through an IIC bus, and is used for realizing the access of the configuration parameters.

[0044] Specifically, the communication interface unit of the control module 12 realizes the long-distance anti-interference communication with the radar module 11 through the RS485 interface, realizes the full-duplex instruction issuing and state returning between the control module 12 and the radio frequency communication module 14 through the SPI interface, and realizes the configuration parameter reading and writing of the EEPROM chip of the data storage module 13 through the master-slave response mechanism through the IIC bus.

[0045] Specifically, the communication between the control module 12 and the radar module 11 is periodic, preferably, the control module 12 actively polls the radar module 11 to obtain the latest traffic flow data packet at a fixed time interval of 500 milliseconds.

[0046] Specifically, the logic discrimination indicates that the MCU performs Boolean operation and state machine jump on the vehicle speed, vehicle distance, lane occupation sign and the like in the data packet based on a preset threshold, and the control instruction indicates a structured data frame containing a target dimming percentage, an interval ID and a timestamp.

[0047] Specifically, after the control module 12 is powered on and initialized, the main MCU unit reads the controller ID, heartbeat interval, vehicle presence brightness, vehicle presence brightness and the like parameters pre-burned into the memory from the data storage module 13 through the IIC bus, then starts a timer to send a query instruction to the radar module 11 through the RS485 interface at a period of 500 milliseconds, after the radar module 11 returns a data frame containing vehicle speed, distance, lane and direction, the main MCU unit analyzes the frame and performs logic discrimination: if the vehicle speed is greater than 0 and the distance is less than 100 meters, it is determined that the interval enters the vehicle presence state, and a dimming instruction frame is immediately generated, the target brightness field in the instruction frame is set to 100%, the interval ID field is set to 0x0A, and the timestamp field is filled with the current system tick value, the instruction frame is sent to the radio frequency communication module 14 at a rate of 10MHz through the SPI interface, and the radio frequency communication module 14 wirelessly forwards the instruction frame to the dimming controller to execute the light-on, at the same time, the main MCU unit writes the vehicle presence event and the instruction content of this discrimination into the log area of the data storage module 13 through the IIC bus. If no valid vehicle data is received for 10 seconds, it is determined that it is a no-vehicle state, and a vehicle presence dimming instruction is generated, the target brightness is set to 5%, and the light is dimmed when the vehicle leaves; in the above process, the main MCU unit sends a heartbeat packet to the radio frequency communication module 14 through the SPI interface to report the running state of the main MCU unit.

[0048] Through the above process, the control module realizes real-time collection of traffic flow data, local calculation, and closed-loop control instruction generation. Compared with protocol conversion and data synchronization between multiple devices in traditional discrete systems, it provides a high-integration, low-latency, and high-reliability control core for tunnel lighting.

[0049] A data storage module 13 for serving as a non-volatile storage space of the Internet of Things tunnel section controller.

[0050] In some embodiments, the data storage module 13 includes an EEPROM and a communication interface unit, and the configuration parameters stored by the data storage module 13 at least include a controller ID, a heartbeat interval, scene parameters, and dimming brightness parameters.

[0051] Specifically, the data storage module 13 is a non-volatile storage unit integrated in the controller, which is composed of an EEPROM chip and an IIC bus communication interface unit. The EEPROM is an electrically erasable programmable read-only memory, and its storage unit realizes persistent charge retention based on a floating gate MOS tube structure, so that data is not lost after power failure. Preferably, the storage capacity is 1K bytes, supporting single-byte random read / write and page write operations.

[0052] Specifically, the communication interface unit includes SCL clock line and SDA data line driving circuits of the IIC bus, and realizes multi-device bus arbitration through pull-up resistors and open-drain output. The non-volatile storage space refers to the logical address area of the controller that can still retain key configuration parameters and operation logs after power module power failure or restart.

[0053] Specific configuration parameters are a set of external setting values required for the control module 12 to execute logical discrimination, at least including a controller ID (device unique identification code), a heartbeat interval (state reporting period), and dimming brightness parameters (target values of brightness in vehicle waiting mode and vehicle presence mode).

[0054] Specifically, during the operation process, whenever the control module 12 obtains new traffic flow information from the radar module 11 through the RS485 interface and executes vehicle presence state discrimination, the main MCU unit writes the discrimination result of this time, the generated control instruction content, and the timestamp into the log page of the EEPROM through the IIC bus; when the operation and maintenance personnel remotely modify the dimming strategy through the radio frequency communication module 14, the new brightness parameters are sent to the control module 12 through the SPI interface, and the main MCU unit immediately writes the new parameters into the EEPROM corresponding address through the IIC bus and performs read-back verification, and updates the local RAM image after confirming the successful writing.

[0055] Preferably, the controller ID, the heartbeat interval, and the dimming brightness parameters are also associated with scene parameters, which are used to identify different scene modes. Through the scene parameters, quick calling of the dimming mode, i.e., multiple preset switching, can be realized.

[0056] Specifically, the module stores the fault code at the same time, when the radar module 11 communication is interrupted, the control module 12 writes the fault type code to the specific address of the EEPROM, which is convenient for subsequent offline diagnosis.

[0057] The data storage module 13 described above can meet the durability requirements of high-frequency parameter update and data storage of tunnel lighting through the characteristics of supporting more than one million write-erase cycles of EEPROM. Such a local storage mechanism can realize data autonomy at the edge, reduce dependence on external servers or cloud platforms, and still provide high-reliability, low-latency, and easy-maintenance data management for tunnel lighting control even in the case of network interruption.

[0058] The radio frequency communication module 14 is used to realize networking and remote management through an Internet of Things communication protocol.

[0059] In some embodiments, the radio frequency communication module 14 includes an Internet of Things communication unit and a communication interface unit, wherein the Internet of Things communication unit is configured to use a Sub-1GHz frequency band and a corresponding Internet of Things communication protocol.

[0060] Specifically, the radio frequency communication module 14 is an Internet of Things communication component integrating a Sub-1GHz Internet of Things communication unit (wireless transceiver unit) and a communication interface unit of an SPI interface; wherein the Sub-1GHz frequency band refers to a radio frequency band below 1G Hz such as 470-510MHz and 868MHz, which has the characteristics of long wavelength, strong diffraction ability, and low transmission loss; the Internet of Things communication protocol refers to a lightweight communication stack developed based on the WF-IoT fusion Internet of Things technology stack, including physical layer modulation, MAC layer channel access, network layer cooperative networking, and application layer data encapsulation specifications.

[0061] Specifically, networking refers to the self-organization of multiple tunnel interval controllers and corresponding multiple intelligent lamps to form a topology structure through a radio frequency link, realizing control instruction broadcasting and state data aggregation, and remote management refers to the remote management of the tunnel interval controllers through the tunnel light control station. Figure 3 In the tunnel on-board light control system shown in the figure, the tunnel light control station adaptively performs parameter configuration, firmware upgrade, state monitoring, fault diagnosis, and other operation and maintenance operations on the interval controllers deployed inside the tunnel through the tunnel light controller as needed.

[0062] Through the above-mentioned radio communication module 14, wireless networking and remote centralized management and control of the tunnel lighting system can be realized. The remote management function enables the operation and maintenance personnel to update the parameters of the full-line controller in batches without entering the tunnel, thereby significantly improving the operation and maintenance efficiency. The use of the Sub-1GHz frequency band significantly improves the penetration capability in the closed environment of the tunnel compared to the traditional 2.4GHz scheme, avoids the same frequency interference of WiFi and Bluetooth, and the interference of bad weather such as rain, snow and fog on wireless communication, which helps to improve the reliability of the system, reduce the number of relay nodes, and reduce the cost and deployment complexity.

[0063] The power module 15 is used as the power supply basis of the Internet of Things tunnel section controller, and is connected with the radar module 11, the control module 12, the data storage module 13 and the radio communication module 14 respectively.

[0064] In some embodiments, the power module 15 is used to receive an alternating input voltage of an external power supply and convert it into a target voltage required by the Internet of Things tunnel section controller, wherein the input voltage supports 85V-305V.

[0065] In some embodiments, the power module 15 at least includes a power protection unit, an AC-DC unit and a DC-DC unit.

[0066] Specifically, the power module 15 is an internal power supply unit integrated in the tunnel section controller, which is composed of a power protection unit, an AC-DC unit and a DC-DC unit in a three-level architecture, and is the basis for providing stable power to the radar module 11, the control module 12, the data storage module 13 and the radio communication module 14.

[0067] Specifically, the alternating input voltage refers to the AC voltage of 220V provided by the tunnel power supply line. Preferably, the power module 15 can support a wide range of 85V to 305V AC power to be compatible with the possible dramatic fluctuations of the tunnel power supply line, thereby improving the stability and reliability of the power supply.

[0068] Specifically, the target voltage refers to the DC voltage supplied to each module after conversion. For example, it includes 5V required by the radar module 11, 3.3V required by the control module 12 and the data storage module 13, and 3.8V required by the radio communication module 14.

[0069] Preferably, the power module 15 meets the safety standards of IEC / EN61558, IEC / EN60335, etc., and passes the IEC / EN / UL62368 certification. It has excellent electromagnetic compatibility, the EMS (electromagnetic sensitivity) level reaches level IV, and the EMI (electromagnetic interference) level meets the CLASS B requirement, ensuring that it is neither disturbed nor disturbs other devices in a complex tunnel electromagnetic environment.

[0070] For example, the power protection unit refers to the fuse, the voltage-dependent resistor and the overcurrent detection circuit integrated in the input end, which is used to cut off the power transmission when short circuit or overload occurs, the AC-DC unit refers to the AC-DC unit composed of the rectifier bridge, the PFC power factor correction circuit and the high-frequency transformer using the switching power supply topology, the DC-DC unit refers to the DC-DC voltage stabilizing unit using the synchronous rectification Buck voltage reducing chip, which is used to accurately reduce the 12V DC bus output by the AC-DC unit to the target voltage of each module.

[0071] Through the above process, the power module realizes wide-range adaptation to the harsh power supply environment of the tunnel and multi-path accurate power supply, can resist abnormal disturbances such as voltage drop and surge in the tunnel, and provides a wide-adaptation, high-reliability and low-energy-consumption power supply infrastructure for tunnel lighting control.

[0072] In some implementations, the control module 12 further comprises a WF-IoT unit, which is used to realize distributed intelligent fog computing among a plurality of control modules 12.

[0073] Specifically, the plurality of control modules 12 can perform multi-section / multi-interval collaborative control and decision-making on the target tunnel based on the distributed intelligent fog computing capability of the WF-IoT unit. The WF-IoT unit is a wireless fusion Internet of Things edge computing unit integrated in the control module 12, which uses Sub-1GHz radio frequency hardware and a lightweight fog computing protocol stack to realize point-to-point or Mesh networking communication among a plurality of tunnel interval controllers. Multi-section / multi-interval collaborative control refers to sharing traffic flow data and jointly deciding the dimming time based on vehicle motion trend prediction and lighting continuity requirements, so as to avoid brightness jump or response lag caused by single-interval independent control. Figure 2 As shown in the sectionalized layout architecture, each interval controller is deployed in a chain along the tunnel, and the vehicle position, speed and local dimming state are exchanged through the WF-IoT protocol frame to form a collaborative control chain.

[0074] Specifically, the distributed intelligent fog computing based on the WF-IoT unit is used to realize the fault emergency handling capability:

[0075] The WF-IoT unit continuously monitors the communication state of the vehicle detector. If the signal is interrupted (such as radar communication disconnection), the unit will automatically determine a fault within 10 seconds (20 500ms detection periods). The system immediately switches to the vehicle mode, which adjusts the luminaires in the tunnel area to the brightest brightness to ensure sufficient lighting and avoid safety risks caused by detection failure. At the same time, the WF-IoT unit actively sends a fault alarm to the tunnel field controller and the cloud platform through the bus or network, including the fault type, location and timestamp, so as to facilitate the rapid positioning of the maintenance personnel.

[0076] When the radar communication is restored, the WF-IoT unit perceives the signal return in real time. The system automatically returns to the vehicle detection dimming mode, dynamically adjusts the lighting brightness according to the actual traffic flow, and realizes the balance between energy saving and comfort. At the same time, the "fault recovery" state is immediately reported to the controller and the platform, forming a complete fault life cycle management.

[0077] In summary, the setting includes: a radar module for non-contact acquisition of traffic flow information; a control module for performing logical discrimination and generating control instructions according to the traffic flow information acquired by the radar module; a data storage module for non-volatile storage space as a tunnel section controller of Internet of Things; a radio frequency communication module for networking and remote management through Internet of Things communication protocol; a power module for power supply as a tunnel section controller of Internet of Things, connected with radar module, control module, data storage module and radio frequency communication module. Further, the technical effects of high integration, accurate vehicle detection, intelligent dimming decision, flexible wireless communication and high reliable data management are realized.

Accordingly, it is intended to embrace all such modifications and variations that fall within the scope of the application.
