Description

Technical Field

[0001] This utility model relates to the field of highway traffic technology, specifically to an installation box for intelligent transportation terminals. Background Technology

[0002] In the field of highway traffic management, real-time collection and efficient processing of traffic data are crucial for ensuring smooth road network operation and improving emergency response capabilities. Currently, the industry generally adopts a model of collecting traffic data using data sensing devices and processing it centrally. These devices include video detectors, loop detectors, and radar detectors, which can collect basic data such as traffic flow, vehicle speed, and vehicle type, and transmit the data to the control center via communication networks for aggregation and analysis. However, this model is limited by its technical architecture and design concepts, resulting in significant shortcomings in functional expansion, area control, and status monitoring.

[0003] From a hardware design perspective, existing data sensing devices mostly adopt integrated solutions, with acquisition, processing, and communication modules highly bundled together, lacking standardized functional expansion interfaces. Different sections of highways have varying monitoring needs, requiring additional functions such as abnormal event identification and road surface condition monitoring. However, integrated devices cannot flexibly integrate external functional modules; expanding functionality necessitates replacing the entire device, making functional expansion difficult and hindering modular upgrades. Regarding area control, existing equipment typically relies on centralized control systems, lacking independent control capabilities. If the centralized control system malfunctions or the network is interrupted, equipment in localized areas will malfunction. Furthermore, equipment operational status monitoring primarily depends on external systems. Data transmission between these external systems and sensing devices is subject to delays and errors, and monitoring indicators are limited, making it difficult to comprehensively and in real-time reflect the actual operating status of the equipment. When equipment malfunctions, alarms are often not issued promptly, leading to delayed response. This not only reduces the flexibility and maintainability of the equipment but may also adversely affect highway traffic safety and operational efficiency.

[0004] Chinese Patent Publication No. CN221746715U discloses a highway operation status fusion perception system, including data sensing equipment. This equipment comprises an ETC gantry, roadside camera equipment, information information boards, vehicle detectors, and voice communication equipment. These devices are interconnected with a road segment central gateway device. All components function as data sensing devices to perceive road traffic conditions. Road segment central gateway devices are deployed on different road segments, aggregating and integrating road segment information into a cloud data center. A firewall connects the road segment central gateway device, the cloud data center, and the server. While this solution can collect and centrally process traffic data using fixed equipment, it struggles to achieve modular functional expansion and independent regional control of the equipment. Furthermore, the equipment operation status monitoring relies on external systems, leading to delayed anomaly responses and reduced equipment flexibility and maintenance efficiency. Utility Model Content

[0005] This utility model aims to provide an installation box for intelligent transportation terminals, which effectively solves the problems in the prior art that make it difficult to realize modular functional expansion and independent area control of equipment, and that the equipment operation status monitoring relies on external systems, resulting in delayed abnormal response and reduced equipment flexibility and maintenance efficiency.

[0006] This application provides the following technical solution: An installation box for intelligent transportation terminals includes a box body and a door rotatably connected to the box body. The box body is equipped with a status monitoring component and a power module. The box body is also equipped with a main control system, a function board assembly, an external device interface module, and an area control module. The main control system includes a controller and a communication module. The controller is electrically connected to the status monitoring component, the power module, the function board assembly, the external device interface module, the area control module, and the communication module, respectively. The functional board assembly includes multiple board slots and functional boards that are pluggably connected to each board slot. Each functional board is electrically connected to the controller through the board slot. The area control module includes multiple independent control units, which are separated and housed in a housing by an isolation structure. Each independent control unit is electrically connected to the controller. The status monitoring component includes an environmental sensor module and an alarm device. The environmental sensor module is electrically connected to the independent control unit, and the alarm device is electrically connected to the output terminal of the controller.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: By incorporating multiple card slots and pluggable functional cards in the functional card assembly, different functional cards can be flexibly inserted or replaced according to actual needs. Each functional card is electrically connected to the controller through its slot, enabling modular expansion of device functionality. In existing technologies, modular expansion of equipment typically requires complete replacement or complex debugging. However, the pluggable card design of this application simplifies expansion operations, reduces maintenance costs, solves the problem of existing technologies' difficulty in achieving modular functional expansion of equipment, and significantly improves the flexibility and adaptability of the equipment. The area control module contains multiple independent control units separated by an isolation structure. Each independent control unit is electrically connected to the controller and can independently control different functional areas within the enclosure. The isolation structure is used to separate the multiple independent control units in the area control module. It can be physically or logically divided. The physical division structure includes physical structures such as partitions and isolation chambers within the enclosure, used to divide the space within the enclosure into multiple independent areas, placing each independent control unit in a different physical space. The logical division structure includes circuit structures such as opto-isolation circuits and electromagnetic isolation components, used to block electrical signal interference and fault transmission between the independent control units. In the existing technology, the internal control of the equipment is usually centralized, without dividing the control part into multiple independent control units through an isolation structure. This means that a failure of a single component may cause the entire system to malfunction, making it impossible to achieve independent control of different functional areas. This is because in centralized control, all control commands and decisions are issued uniformly by a central controller. Each controlled part has no autonomous control capability and completely relies on the instructions of the central controller to execute operations. Once the central controller fails, the entire system may be paralyzed, and it is difficult to perform targeted control of different parts within the system. The regional control in this application can divide the system into multiple independent regions, each with an independent control unit. The independent control unit can autonomously make decisions and control the operation of equipment within its region within a certain range, while also interacting with the central controller. A failure in one region will not affect the normal operation of other regions, thus improving the reliability and maintainability of the system. A single component failure may lead to an abnormality in the entire system. However, this application separates the independent control units through an isolation structure, effectively preventing the spread of faults and ensuring that each region operates independently. This solves the problem that existing technologies cannot achieve independent regional control, and improves the reliability and maintenance efficiency of the equipment.

[0008] The status monitoring component includes an environmental sensor module and an alarm device. The environmental sensor module is electrically connected to an independent control unit and can monitor environmental and operating parameters such as temperature, humidity, voltage, and current within the enclosure in real time. The alarm device is electrically connected to the controller output and directly triggers a local alarm when an anomaly is detected. In existing technologies, equipment status monitoring relies on external systems, and abnormal information needs to be transmitted and processed externally, resulting in response delays. Unlike existing technologies that rely on external systems for equipment status monitoring, this application achieves internal autonomous real-time monitoring, significantly shortening the anomaly response time, enabling timely detection and handling of problems, improving the stability and reliability of equipment operation, and reducing potential risks caused by response delays.

[0009] Furthermore, the main control system also includes a storage chip integrated on the circuit board of the main control system. The data interface of the storage chip is electrically connected to the data bus of the controller, and the signal interface of the communication module is electrically connected to the communication port of the controller. The storage chip receives and stores the operating data transmitted by the controller through the data bus, and the communication module receives control commands and transmits data to external integrated operation and maintenance management equipment through the communication port of the controller.

[0010] By integrating the storage chip onto the main control system's circuit board and electrically connecting its data interface to the controller's data bus, the system can directly and efficiently receive and store the operating data transmitted by the controller via the data bus, reducing intermediate data transmission links and improving the timeliness and accuracy of data storage. The communication module's signal interface is electrically connected to the controller's communication port, enabling it to quickly receive control commands through the communication port and smoothly transmit data to external integrated operation and maintenance management equipment, enhancing the main control system's data interaction capabilities with external devices and improving overall operating efficiency and stability.

[0011] Furthermore, the enclosure is also equipped with an industrial Ethernet switching device. The external device interface module includes an industrial Ethernet interface. The industrial Ethernet switching device is electrically connected to the controller through the industrial Ethernet interface.

[0012] The system enables rapid internal data exchange through industrial Ethernet switching equipment, ensures accurate transmission of control commands through electrical connection with the controller, and connects to external devices through communication modules, facilitating remote operation and maintenance management and improving the overall operating efficiency and reliability of the system.

[0013] Furthermore, the functional board component includes a video monitoring board, an intelligence board monitoring board, and a peripheral status monitoring board. The external device interface module also includes a video interface, an intelligence board interface, and a peripheral interface. The video monitoring board is electrically connected to the communication module and the video interface, respectively. The intelligence board monitoring board is electrically connected to the communication module and the intelligence board interface, respectively. The peripheral status monitoring board is electrically connected to the communication module and the peripheral interface, respectively.

[0014] By setting up video monitoring boards, information board monitoring boards, and peripheral status monitoring boards, along with corresponding video interfaces, information board interfaces, and peripheral interfaces, direct electrical connection and data exchange between each monitoring function and its corresponding external device are achieved. This enables the equipment to perform specialized status monitoring of video equipment, information boards, and various peripherals on highways, improving data transmission efficiency and monitoring accuracy, and enhancing the system's adaptability and management capabilities for different devices.

[0015] Furthermore, the video monitoring board includes a video decoding chip and an interface connector. The input end of the video decoding chip is connected to the output end of the video interface via a coaxial cable, and the output end of the video decoding chip is connected to the input end of the communication module via a ribbon cable.

The input end of the sensor interface is connected to the output end of the peripheral interface via a shielded wire, and the output end of the signal conditioning circuit is connected to the input end of the communication module via a printed circuit board trace.

[0016] The video decoding chip in the video monitoring board is connected to the video interface and the communication module via coaxial cable and ribbon cable to achieve efficient video decoding and transmission; the information board control chip in the information board monitoring board is connected to the information board interface via RS485 bus, and the status is accurately displayed with the help of the status indicator; the peripheral status monitoring board uses the sensor interface to connect to the peripheral interface and the communication module via shielded wire, signal conditioning circuit and printed circuit board traces to ensure stable and accurate signal monitoring.

[0017] Furthermore, the enclosure also includes a smart circuit breaker module. The power module includes an input voltage module and a backup power module. The input voltage module is electrically connected to the controller. The environmental sensor module includes a voltage sensor, a current sensor, and a leakage current sensor.

Each power output unit is electrically connected to the controller through a current limiting protection circuit. The smart circuit breaker module is electrically connected to the backup power module through a power switching circuit.

[0018] By setting up a smart circuit breaker module, which has built-in multiple power output units and each power output is electrically connected to the controller through a current limiting protection circuit, it can accurately control multiple power sources and achieve current limiting protection, thereby improving power safety. The smart circuit breaker module is connected to the controller through a smart circuit breaker control interface for easy intelligent operation. The backup power module is connected to the controller and the smart circuit breaker module through a backup power switching interface, which can quickly switch power sources to ensure power supply. The environmental sensor module is electrically connected to the controller and can monitor voltage, current, and leakage current in real time, providing data for intelligent management, thus achieving intelligent and safe power management as a whole.

[0019] Furthermore, the dynamic environment sensor module also includes a temperature sensor, a humidity sensor, a water immersion sensor, a smoke sensor, a door magnetic sensor, and a vibration sensor, which are electrically connected to the input terminal of the independent control unit.

[0020] By adding temperature, humidity, water immersion, smoke, door magnetic sensor, and vibration sensor to the environmental sensor module, all of which are electrically connected to the input terminal of the independent control unit, the temperature, humidity, water immersion, smoke, door opening and closing, and vibration inside the enclosure can be comprehensively monitored in real time. This allows for more timely and accurate detection of anomalies, providing rich data to the independent control unit so that countermeasures can be taken quickly to ensure the safe and stable operation of the enclosure and its internal equipment.

[0021] Furthermore, the enclosure is also equipped with an expansion slot, and the functional board assembly also includes an edge computing board, which is inserted into the expansion slot and electrically connected to the controller.

[0022] By setting up an expansion slot inside the enclosure and equipping it with an edge computing board that can be plugged in and electrically connected to the controller, the computing resources can be flexibly expanded compared to existing technologies, data can be processed locally, data transmission latency can be reduced, and system response speed and processing capacity can be improved.

[0023] Furthermore, the alarm device includes an audible and visual alarm and a remote alarm interface, which are electrically connected to the output of the controller.

[0024] By setting up an audible and visual alarm and a remote alarm interface that are electrically connected to the controller output respectively, the audible and visual alarm can issue a conspicuous audible and visual warning on site in a timely manner, and the alarm information can be quickly transmitted to the remote monitoring terminal through the remote alarm interface, so as to realize synchronous alarm on site and remote, and improve the fault response speed and processing efficiency.

[0025] Furthermore, a snapshot camera is also installed inside the enclosure. The snapshot camera is electrically connected to the controller, and the lens of the snapshot camera faces the opening direction of the enclosure door.

[0026] By installing a camera inside the enclosure that is electrically connected to the controller and has its lens facing the opening direction of the enclosure door, the camera can capture images of the scene in a timely manner when the enclosure door is opened abnormally and transmit them to the controller, effectively recording abnormal situations such as illegal intrusion.

[0027] Figure 1 This is a logic block diagram of the installation box for the intelligent transportation terminal of this utility model; Figure 2 This is a perspective view of the installation box for the intelligent transportation terminal of this utility model. Detailed Implementation

[0028] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: 1. Cabinet; 2. Main control system; 3. Cabinet door; 4. Power module; 5. Functional board assembly.

[0029] like Figures 1 to 2 As shown, the installation box for the intelligent transportation terminal includes a box body 1 and a door 3 rotatably connected to the box body 1. The box body 1 is equipped with a status monitoring component and a power module 4. The box body 1 is also equipped with a main control system 2, a function board assembly 5, an external device interface module and an area control module. The main control system 2 includes a controller and a communication module. The controller is electrically connected to the status monitoring component, the power module 4, the function board assembly 5, the external device interface module, the area control module and the communication module respectively. The functional board assembly 5 includes multiple board slots and functional boards that can be plugged into each board slot. Each functional board is electrically connected to the controller through the board slot. The area control module includes multiple independent control units, which are separated and set in the housing 1 by an isolation structure. The independent control units are electrically connected to the controller. The status monitoring component includes an environmental sensor module and an alarm device. The environmental sensor module is electrically connected to the independent control unit, and the alarm device is electrically connected to the output of the controller.

[0030] In this embodiment, the controller is a PLC, which stands for Programmable Logic Controller, preferably a Siemens S7-1500 PLC.

[0031] The independent control units are separated and set inside the enclosure by an isolation structure. In terms of physical division, the internal space of the enclosure is divided into multiple independent areas by physical structures such as partitions and isolation chambers. For example, the partitions can be made of metal plates with a thickness of 2-5mm (such as 304 stainless steel plates, the model can be customized according to the size of the enclosure), or plastic partitions (such as polycarbonate plates, the model is adapted to the actual enclosure). The isolation chambers can be constructed by setting a metal frame of a specific shape inside the enclosure (such as aluminum alloy frames, the model is designed according to the internal layout of the enclosure), placing each independent control unit in a different physical space, so that they are physically isolated from each other. In terms of logical partitioning, circuit structures such as opto-isolation circuits and electromagnetic isolation components are used to block electrical signal interference and fault transmission between independent control units. Opto-isolation circuits can use optocouplers such as the TLP521 model, and electromagnetic isolation components can use digital isolators such as the ADuM1201 model. Through these logical partitioning structures, the independent control units are electrically isolated, thereby ensuring that each independent control unit can make autonomous decisions and control the operation of equipment in its own area within a certain range, and can also interact with the central controller. Furthermore, a fault in one area will not affect the normal operation of other areas.

[0032] The enclosure 1 is made of one-piece die-cast aluminum alloy with a thickness of ≥2.5mm and a powder-coated frosted finish. Enclosure 1 features protection against vandalism, vibration, electromagnetic interference, dust, moisture, fog, high temperatures, rust, and lightning strikes. Enclosure 1 is equipped with a high-performance 64-bit processor running Android 7.x, featuring a dual-core A72 CPU and a quad-core A53 CPU, along with a quad-core GPU. It has at least 16GB of RAM and at least 8GB of storage space, supports TF card expansion, includes a built-in 4G network module, a 5-inch full-color screen, and supports BeiDou and GPS positioning and time synchronization.

The operating environment for this intelligent transportation terminal installation enclosure is -20℃ to +65℃ and 10%RH to 90%RH (non-condensing).

[0033] Specifically, the main control system 2 also includes a storage chip integrated on the circuit board of the main control system 2. The data interface of the storage chip is electrically connected to the data bus of the controller, and the signal interface of the communication module is electrically connected to the communication port of the controller. The storage chip receives and stores the operating data transmitted by the controller through the data bus, and the communication module receives control commands and transmits data to external integrated operation and maintenance management equipment through the communication port of the controller.

[0034] In this embodiment, the storage chip selected is the Microchip 24LC256 I2C interface EEPROM. Its circuitry is integrated on the main control system 2 circuit board. The SDA (data) and SCL (clock) pins of the 24LC256 are electrically connected to the I2C communication interface of the Siemens S7-1500 PLC via wires (the I2C function can be expanded through the PLC's digital input / output module). In the PLC program, I2C communication instruction blocks are used to read and write to the 24LC256, realizing the reception and storage of runtime data.

[0035] The communication module uses the Siemens CP1543-1. This module is electrically connected to the communication port of the S7-1500 PLC via a PROFINET or Ethernet interface. In the PLC's hardware configuration, the CP1543-1 is added to the project and configured. In the program, communication instructions (such as PUT / GET instructions) are used to receive control commands from external integrated operation and maintenance management equipment via the CP1543-1, and simultaneously transmit processed data to the external integrated operation and maintenance management equipment through this module.

[0036] The external integrated operation and maintenance management equipment first establishes a physical and data connection with the communication module of the main control system 2 via a standardized communication bus (such as RS485, RJ45, industrial Ethernet, or MQTT). The controller in the main control system 2 transmits operational data via the data bus to a storage chip integrated on the circuit board. The communication module, through an electrical connection with the controller's communication port, receives control commands from the external management equipment and transmits them to the controller. Simultaneously, it aggregates the operational data, edge-sensing data, and edge-fusion data stored in the storage chip and uploads them to the external integrated operation and maintenance management equipment via the standardized communication bus. The external management equipment then integrates the uploaded multi-source status data, including video, data, network, and energy consumption, and leverages AI... The computing power is used to mine and analyze this data. In the anomaly detection stage, abnormal data is identified by comparing real-time monitoring parameters of equipment assets with preset normal thresholds and analyzing whether the data transmission patterns deviate from the norm. In the pattern recognition stage, features are extracted from multi-source data to distinguish different data patterns, such as the normal operation mode of hazardous chemical vehicles and the abnormal pattern of large vehicles with small labels evading fees. In the early warning analysis stage, based on the anomaly detection results and the abnormal patterns identified by pattern recognition, combined with unified data storage and visualization functions, early warning information is generated. The early warning information or control instructions are transmitted back to the communication module of the main control system 2 via a standardized communication bus, and then transmitted to the controller. The controller adjusts the operating status according to the instructions, and the adjusted operating data is then uploaded to the external integrated operation and maintenance management equipment through the above path to achieve closed-loop intelligent management from end to cloud.

Simultaneously, it supports short-range management methods such as WEB, SSH, and TELNET, and possesses power and network surge protection capabilities to ensure the stable operation of industrial Ethernet switching equipment.

The input of the video decoding chip is connected to the output of the video interface via an RG59 coaxial cable. The RG59 coaxial cable effectively transmits video signals and reduces signal loss. The output of the video decoding chip is connected to the input of the communication module (such as the STM32F407ZGT6) via an FFC cable. The FFC cable is small and lightweight, making it suitable for internal board connections. In the circuit design, a suitable power supply circuit is configured for the video decoding chip, using an AMS1117-3.3 voltage regulator chip to provide a stable 3.3V power supply, while adding filter capacitors to reduce power supply noise.

[0042] The information board monitoring board uses the STC89C52RC microcontroller as its control chip. This microcontroller offers high cost-effectiveness and stable performance, meeting the control requirements of the information board. Common LED indicators are used for status display, connected to the output of the information board control chip via a current-limiting resistor. The communication terminal of the information board control chip converts TTL level to RS485 level using a MAX485 chip, and then connects to the communication terminal of the information board interface via a twisted pair cable, achieving reliable long-distance communication. In the circuit design, a clock circuit and a reset circuit are configured for the microcontroller. A 12MHz crystal oscillator provides the clock signal, and a manual reset button implements the reset function. Appropriate decoupling capacitors are also added to ensure stable chip operation.

[0043] The sensor interface of the peripheral status monitoring board uses TE Connectivity's 1-1734592-0 connector, which has excellent shielding performance and can effectively reduce external interference. The signal conditioning circuit uses the AD620 instrumentation amplifier, which features high precision and low noise, making it suitable for amplifying and conditioning sensor signals. The input of the sensor interface is connected to the output of the peripheral interface via shielded twisted-pair cable, which effectively suppresses electromagnetic interference. The output of the signal conditioning circuit is connected to the input of the communication module (such as STM32F407ZGT6) via printed circuit board traces.

[0046] In this embodiment, the intelligent circuit breaker module uses the DH-IAS1262C-B model. This DH-IAS1262C-B model is a typical AC220V 2P intelligent circuit breaker. The AC220V 2P intelligent circuit breaker supports status monitoring (voltage, current, energy consumption), remote closing and opening, and can be connected to the main control system 2 via RS485 / RJ45 interfaces to achieve remote monitoring and control. The input voltage module of the power supply module 4 is connected to an external AC power supply and is connected to the controller via a wire, using a 2.5V power supply. The copper core wires ensure stable power supply.
