Description

Technical Field

[0001] This invention relates to the field of traffic control box technology, specifically to a modular intelligent traffic control box and its control method and control system. Background Technology

[0002] Modular intelligent traffic control enclosures are critical infrastructure of intelligent transportation systems, typically deployed along roads to house key electronic devices such as traffic light controllers, detectors, and communication equipment. With the rapid development of smart cities and intelligent transportation networks, the operational reliability of these enclosures directly impacts road traffic safety and efficiency. However, traditional traffic enclosures have relatively limited functionality, relying primarily on manual periodic inspections or reactive responses to malfunctions, making it difficult to achieve 24 / 7, real-time intelligent monitoring and maintenance. Existing enclosure monitoring solutions have several shortcomings: First, functional modules are often set up independently; for example, power monitoring, access control alarms, and temperature control systems lack collaborative capabilities, forming information silos that prevent unified management and intelligent decision-making at the system level. Second, in terms of early warning and handling of abnormal situations, existing solutions typically only provide basic power outage or door magnetic alarm functions. They lack comprehensive, proactive perception and efficient response mechanisms for various complex operating conditions that enclosures may encounter, such as network interruptions, internal environmental anomalies (e.g., water immersion, temperature runaway), and physical damage (e.g., collisions, tipping over). Furthermore, the power supply and communication reliability of the internal equipment are insufficient. When the mains power fails or the primary communication link is interrupted, the switching strategy for the backup power supply is not intelligent enough, and the redundancy guarantee mechanism for the backup communication channel is inadequate. This may lead to the loss of critical alarm information or equipment shutdown, thereby causing traffic hazards. Therefore, there is an urgent need in this field for a highly integrated, intelligent modular intelligent chassis control method and system for traffic control with proactive operation and maintenance capabilities to overcome the shortcomings of existing technologies and improve the robustness and management level of the entire traffic control system.

[0003] Therefore, existing technologies still need further development. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a modular intelligent chassis for traffic control and its control method and control system to solve the problems existing in the prior art.

[0005] To achieve the above-mentioned technical objectives, according to a first aspect of the present invention, the present invention provides a control method for a traffic control modular intelligent chassis, comprising: S100: Real-time monitoring of various status and environmental parameters of the chassis; S200. When an abnormality is detected in the status parameter, an alarm message is generated; S300. Send the alarm information to the monitoring platform via the selected communication method; S400: Based on the monitored internal temperature and / or internal humidity of the chassis, control the environmental control device to adjust the internal temperature and / or internal humidity of the chassis. The S500 automatically switches to backup power when a mains power outage is detected.

[0006] Specifically, S100 includes monitoring the physical safety status and electrical status of the chassis.

[0007] Specifically, the physical security state includes at least one of the following: the door is open, the physical damage state, and the water immersion state.

[0008] Specifically, when the door is detected to be open, an alarm message is generated and logged.

[0009] Specifically, when physical damage is detected, an anti-vandalism alarm is generated, wherein the physical damage includes at least one of collision, tipping, and displacement.

[0010] Specifically, when water immersion is detected, a water immersion alarm is generated.

[0011] Specifically, the electrical status includes mains power status and network communication status.

[0012] Specifically, the mains power status includes at least one of power outage, power restoration, low voltage, and high voltage. When an abnormal mains power status is detected, a mains power alarm message is generated.

[0013] According to a second aspect of the present invention, a control system for a traffic control modular intelligent chassis is provided, comprising: The monitoring module is used to monitor various status and environmental parameters of the chassis in real time. An alarm module is used to generate alarm information when the status parameter is detected to be abnormal; A communication module is used to send the alarm information to the monitoring platform via a selected communication method; The control module is used to control the environmental control device to regulate the internal temperature and / or internal humidity of the chassis based on the monitored internal temperature and / or internal humidity of the chassis. The power management module is used to automatically switch to the backup power supply when a mains power outage is detected.

[0014] According to a third aspect of the present invention, a traffic control box is provided, comprising: a memory; and a processor, wherein the memory stores computer-readable instructions, which, when executed by the processor, implement the control method of the traffic control modular intelligent box described above.

[0015] Beneficial effects: The control method and system for the modular intelligent chassis for traffic control provided by this invention have produced significant and multifaceted beneficial effects compared to existing technologies.

[0016] This invention constructs a highly integrated and intelligent monitoring system, achieving comprehensive, real-time perception and collaborative control of the internal and external states of the chassis. By combining freely selectable modular units with unified intelligent control logic, it breaks through the limitations of single-function solutions in traditional approaches. Specifically, through control methods, it organically integrates multiple aspects such as monitoring, alarm, communication, and control, achieving automation of chassis management, greatly reducing reliance on manual inspections, lowering maintenance costs, and significantly improving the overall reliability and response speed of the traffic control system.

[0017] This invention clearly distinguishes between physical security status and electrical status of the monitored objects, ensuring comprehensive monitoring coverage and timely detection of both structural integrity issues and internal electrical parameter anomalies. The included door opening alarm and log recording functions not only enhance the physical security of the enclosure but also provide reliable data support for event tracing. The vandalism detection function can quickly respond to malicious damage or accidental events such as collisions and tipping, effectively protecting public assets. Water immersion detection extends the enclosure's adaptability to harsh environments (such as heavy rain and pipe leaks), preventing equipment damage caused by water immersion.

[0018] This invention is particularly effective in ensuring electrical stability. Mains power status monitoring prevents equipment malfunctions caused by poor power quality, while network status monitoring ensures uninterrupted data transmission. The combination of these two features provides dual protection for the continuous and stable operation of the chassis. The entire control method is driven by intelligent algorithms (such as PID temperature control and communication link optimization), achieving optimization of energy consumption and performance.

[0019] This invention provides a temperature and humidity coordinated control scheme, solving the condensation problem inside equipment under high humidity environments and greatly reducing the risk of short circuits caused by condensation. By setting reasonable thresholds and introducing a hysteresis control algorithm, it ensures timely control while avoiding mechanical wear and energy waste of actuators, thus improving the stability and lifespan of the entire control system. It intelligently judges the primary problem (whether it is overheating or overhumidity) and prioritizes the most urgent situation (such as prioritizing heat dissipation), reflecting an intelligent environmental management strategy.

[0020] The beneficial effects of the control system of this invention lie in its innovative hardware design. The modular, freely selectable configuration provides the system with great flexibility and scalability, enabling it to adapt to the customized needs of different application scenarios. The integration of an independent backup power supply and multiple communication methods constitutes a highly available power supply and communication backup system, ensuring that the system can still maintain core monitoring and alarm functions in extreme situations such as power outages or network failures. The addition of lightning protection devices and a power-adaptive temperature control system improves the environmental adaptability and service life of the equipment from a physical perspective. In summary, this invention, through the organic combination of method and system, provides users with a complete, reliable, intelligent, and easy-to-implement modular intelligent chassis solution for traffic control.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, the directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right" in this preferred embodiment, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0023] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0024] Please see Figure 1-4 This invention provides a control method for a modular intelligent chassis for traffic control, comprising: S100: Real-time monitoring of various status and environmental parameters of the chassis.

[0025] Specifically, S100 includes monitoring the physical safety status and electrical status of the chassis.

[0026] Specifically, the physical security state includes at least one of the following: the door is open, the physical damage state, and the water immersion state.

[0027] Specifically, the electrical status includes mains power status and network communication status.

[0028] Specifically, the mains power status includes at least one of power outage, power restoration, low voltage, and high voltage. When an abnormal mains power status is detected, a mains power alarm message is generated.

[0029] Specifically, when a network communication interruption is detected, a network alarm message is generated.

[0030] It should be further explained that the specific scheme of S100 includes: The control unit monitors the chassis's status parameters in real time, including physical safety status and electrical status. Physical safety status includes door open status, physical damage status (preferably collision, tipping, and displacement in this embodiment), and water immersion status. Electrical status includes mains power status (preferably power outage, power restoration, low voltage, and high voltage in this embodiment) and network communication status. Monitoring is achieved by reading data from the detector unit. The door opening status is detected by a reed switch. When the door is opened, the switch status changes, immediately triggering the monitoring.

[0031] Physical damage is detected by a triaxial accelerometer, which outputs acceleration values. To determine an anomaly, the resultant acceleration is calculated and its changes are compared. The preferred formula for the resultant acceleration in this embodiment is as follows: in, , , These represent the acceleration values ​​along the X, Y, and Z axes (unit: m / s²). This represents the resultant acceleration. The change in resultant acceleration (i.e., the current value versus the static reference value) is... When the absolute value of the difference exceeds a threshold, it is considered physical damage. The threshold is preferably 2g (approximately 19.6 m / s²), based on experimental data: in common collision or tipping events, the acceleration change is usually greater than 2g, while environmental vibration is usually less than 1g; this threshold can effectively reduce false alarms. Static reference value. Calibrate at system startup and take the average value over 10 seconds.

[0032] The immersion state is detected by a water immersion sensor, which is triggered when the resistance between the sensor electrodes changes.

[0033] The mains power status is detected by a voltage sensor to monitor the voltage value. The preferred low voltage threshold is 198V (10% below the nominal 220V), and the preferred high voltage threshold is 242V (10% above the nominal 220V). The reason is that, according to the power grid standard (preferably GB / T12325 in this embodiment), these thresholds can identify common voltage anomalies and prevent equipment damage.

[0034] Network communication status is detected via a heartbeat mechanism. The control unit sends a heartbeat packet to the monitoring platform every 5 seconds. If no response is received after 3 consecutive heartbeats, the communication is considered interrupted. This setting is designed to minimize the impact of network latency and ensure timely fault detection.

[0035] S200. When an abnormality is detected in the status parameter, an alarm message is generated.

[0036] Specifically, when the door is detected to be open, an alarm message is generated and logged.

[0037] Specifically, when physical damage is detected, an anti-vandalism alarm is generated, wherein the physical damage includes at least one of collision, tipping, and displacement.

[0038] Specifically, when water immersion is detected, a water immersion alarm is generated.

[0039] It should be further explained that when any abnormal status parameter is detected, the control unit generates an alarm message. The alarm message includes a timestamp, anomaly type, and a specific value (preferably temperature or voltage in this embodiment). An alarm is generated and logged upon opening the enclosure door; the log is stored in the control unit's non-volatile memory for easy auditing. Alarm priorities are configurable; in this embodiment, physical damage alarms are preferred as the highest priority.

[0040] S300. The alarm information is sent to the monitoring platform via the selected communication method.

[0041] It should be further explained that alarm information is sent to the monitoring platform (preferably a cloud platform or a local server in this embodiment) via the communication unit. Communication methods support private networks, wireless networks, and the internet, with wired internet used by default (low cost and reliable). When a wired network interruption is detected, it automatically switches to a wireless network (preferably 4G in this embodiment). The switching delay is preferably less than 5 seconds, based on actual network timeout settings to ensure timely alarm response. The communication protocol uses MQTT and supports data encryption.

[0042] S400: Based on the monitored internal temperature and / or internal humidity of the chassis, control the environmental control device to adjust the internal temperature and / or internal humidity of the chassis.

[0043] It should be further explained that step S400 mainly addresses temperature regulation. A temperature detector monitors the internal temperature of the chassis in real time, and the control unit controls the exhaust or heating device based on the temperature value. Temperature threshold settings: The high-temperature threshold is preferably 40°C, and the low-temperature threshold is preferably 0°C. The reason is based on the operating temperature range of electronic components (typically 0°C to 70°C). A 40°C threshold prevents overheating, and a 0°C threshold avoids condensation at low temperatures. Temperature control employs a proportional-integral-derivative (PID) algorithm to achieve precise regulation. The preferred PID algorithm formula in this embodiment is as follows: in, This indicates the control output (in this embodiment, the preferred output is fan speed or heater power, normalized to 0-100%). Indicates the error (i.e., the difference between the set temperature and the actual temperature, in °C). , , This represents the PID parameters. Preferred parameter values ​​are: , , The rationale is that by tuning using the Ziegler-Nichols method, a fast response (overshoot less than 5%) and near-zero steady-state error are achieved in simulations. The set temperature can be adaptively adjusted according to the season: 25°C for summer and 10°C for winter, based on a balance between human comfort and equipment efficiency. The algorithm updates its output every second.

[0044] Furthermore, in other preferred embodiments of the present invention, the environmental condition detection unit includes a temperature sensor and a humidity sensor. To achieve high-precision and high-stability monitoring, a preferred embodiment of the present invention employs an integrated temperature and humidity sensor, such as the HDC1080 digital temperature and humidity sensor. This sensor is connected to the main control unit (e.g., a microcontroller MCU) via an I2C bus. Its specific operating parameters are as follows: temperature measurement range is -40°C to +125°C, with a typical accuracy of ±0.2°C; humidity measurement range is 0% to 100% relative humidity (RH), with a typical accuracy of ±2%RH. The sampling period can be set to 5 seconds. This period value is an optimal value determined after balancing response timeliness and system power consumption, which can quickly capture environmental changes while avoiding excessive MCU load due to overly frequent sampling.

[0045] Furthermore, the environmental control device mainly includes an exhaust system for heat dissipation (such as a DC brushless fan) and a heating system for dehumidification (such as a PTC heater). The exhaust system is installed on the top or upper side wall of the chassis to form a bottom-up heat dissipation airflow; the heating system is installed at the bottom of the chassis to avoid localized accumulation of hot air.

[0046] It should be further noted that the control logic is implemented by an algorithm program preset in the main control unit. This algorithm is based on the monitored temperature value (T) and humidity value (H), compares them with preset thresholds, and outputs control instructions. The thresholds are set based on the safe operating ranges of typical electronic components (such as CPUs and power modules) inside the chassis and the prevention of condensation. Through a large number of experimental verifications, the preferred value of the temperature threshold (T_threshold) is 45°C, and the preferred value of the humidity threshold (H_threshold) is 80%RH. The reason for choosing 45°C as the temperature threshold is that the upper limit of the long-term operating junction temperature of most electronic components is above 85°C, and leaving a temperature difference margin of more than 40°C is sufficient to cope with the superposition effect of internal heat generation and external high temperature, ensuring the thermal reliability of the system. The reason for choosing 80%RH as the humidity threshold is to start dehumidification in time before the temperature inside the chassis may drop below the dew point due to a sudden cold in the external environment, prevent the formation of condensed water, and thus avoid circuit short circuits or corrosion.

[0047] Specifically, the control algorithm is implemented through the following decision logic: 1. When T≥T_threshold: Regardless of the current humidity value, the system preferentially starts the exhaust device for forced heat dissipation until the temperature T drops below T_threshold by a deadband temperature (e.g., 3°C) and then stops. This logic ensures that temperature control has the highest priority; 2. When T<T_threshold and H≥H_threshold: The system starts the heating device for dehumidification. Heating can effectively increase the temperature of the air inside the chassis, thereby reducing its relative humidity and preventing condensation. When the humidity H drops below H_threshold by a deadband humidity (e.g., 5%RH), the heating device stops working; 3. When T<T_threshold and H<H_threshold, but both T and H are at relatively high levels (e.g., T>35°C and H>70%RH): The system can start the exhaust device for mild ventilation. This strategy helps to replace the air inside and outside the chassis, perform preventive adjustment when the temperature and humidity do not exceed the standard, and improve energy efficiency; It should be further noted that to optimize the control smoothness and prevent the actuators (fans, heaters) from frequently starting and stopping near the thresholds, the present invention introduces a hysteresis control mechanism. Its mathematical expression is as follows: ① Fan start-stop conditions: ② Heater start-stop conditions: Where: represents the temperature value inside the chassis monitored in real time, in degrees Celsius (°C); This represents the real-time humidity level inside the chassis, expressed as a percentage of relative humidity (%RH). This represents a preset temperature threshold, with a preferred value of 45°C. This represents the preset humidity threshold, with a preferred value of 80%RH; The hysteresis of temperature control is 3°C, which is used to prevent the fan from frequently switching on and off when the temperature fluctuates slightly around the threshold. The hysteresis representing humidity control, with a preferred value of 5%RH, serves the same purpose of preventing frequent heater operation when humidity fluctuates around the threshold. This indicates the operating status of the exhaust system (on or off). This indicates the operating status of the heating device (on or off).

[0048] The S500 automatically switches to backup power when a mains power outage is detected.

[0049] It should be further explained that the power supply unit monitors the mains power status. When the mains power fails, it automatically switches to the backup power supply, with a switching time preferably less than 10ms, based on UPS standards to avoid system restart. The backup power supply's charging management adopts a constant current-constant voltage mode, with a preferred charging current of 5A, because a 100Ah battery can be fully charged in 20 hours, balancing charging speed and battery life.

[0050] Furthermore, the control unit integrates intelligent algorithms. Temperature trend prediction uses a moving average algorithm to proactively activate the temperature control device. The preferred algorithm formula in this embodiment is as follows: in, This indicates the predicted temperature (unit: °C). Indicates historical temperature values. The window size is indicated, preferably 10, because it is based on short-term temperature change patterns (in this embodiment, the outdoor temperature fluctuation period is preferred), and n=10 can smooth random fluctuations and respond quickly. If the predicted temperature is close to the threshold, the control unit adjusts the temperature device in advance to reduce energy consumption.

[0051] Communication redundancy mechanism: The communication unit monitors the status of each communication link in real time and uses a weighted round-robin algorithm to select the optimal link. Link quality score. The calculation is as follows: in, Indicates round-trip time delay (unit: ms). This indicates the packet loss rate (in %). and The weights are 0.7 and 0.3, with preferred values ​​of 0.7 and 0.3 respectively, because latency is the primary metric. The link with the lowest score is used first to ensure reliability.

[0052] Please continue reading. Figure 1-4 The present invention provides another embodiment, which provides a control system for a traffic control modular intelligent chassis. The control system for the traffic control modular intelligent chassis includes: The monitoring module 100 is used to monitor various status parameters and environmental parameters of the chassis in real time. Alarm module 200 is used to generate alarm information when the status parameter is detected to be abnormal; The communication module 300 is used to send the alarm information to the monitoring platform through a selected communication method; The control module 400 is used to control the environmental control device to adjust the internal temperature and / or internal humidity of the chassis based on the monitored internal temperature and / or internal humidity of the chassis. The power management module 500 is used to automatically switch to the backup power supply when a mains power failure is detected.

[0053] In a preferred embodiment of the present invention, the traffic control modular intelligent chassis includes: The chassis body has a standard guide rail 1 inside; Multiple functional units 2, which can be freely selected and installed on the standard guide rail 1, include a detector unit, a power supply unit, a communication unit, and a control unit; The detector unit includes at least one of a door detector, a mains power detector, a network detector, a temperature detector, a water immersion detector, and a physical damage detector, used to detect the status parameters of the chassis; The power supply unit includes an AC power interface and a rechargeable battery backup power supply, which is used to automatically switch to the backup power supply when the AC power fails. The communication unit supports at least one of private network, wireless network and Internet communication methods and is used to communicate with the monitoring platform. The control unit is connected to the detector unit, the power supply unit and the communication unit, and is used to generate alarm information based on the detection data and control the temperature regulation device. Lightning protection devices are connected to the mains power inlet to protect electrical appliances. The temperature regulating device includes an exhaust device and a heating device, which are controlled by the control unit.

[0054] It should be further explained that the system hardware of the traffic control modular intelligent chassis includes the chassis body, multiple functional units 2, lightning protection devices, and temperature control devices. The chassis body is made of metal (preferably galvanized steel sheet in this embodiment) and has a standard guide rail 1 (compliant with DIN EN 60715 standard) inside. The guide rail is mounted on the frame at the bottom of the chassis, facilitating free selection of units. The functional units 2 are mounted on the guide rail in a modular manner and include detector units, power supply units, communication units, and control units. The detector units include a door detector (preferably a reed switch in this embodiment), a mains power detector (a sensor that can detect voltage and current, preferably a voltage transformer in this embodiment), a network detector (monitoring network connectivity through heartbeat packets), a temperature detector (a digital temperature sensor, preferably DS18B20 in this embodiment), a water immersion detector (optional, preferably a water immersion sensor based on the electrode principle in this embodiment), and a physical damage detector (preferably a triaxial accelerometer in this embodiment). The power supply unit includes an AC 220V input mains interface and an independent rechargeable battery backup power supply (preferably a lithium-ion battery pack with a capacity of 100Ah in this embodiment). The backup power supply can automatically switch during mains power outages to ensure continuous operation of the unit. The communication unit supports multiple communication methods: private network (preferably via a fiber optic modem in this embodiment), wireless network (preferably a 4G / 5G module in this embodiment), and internet (preferably an Ethernet interface in this embodiment). These methods can be configured in primary / backup mode to achieve redundant communication. The control unit uses a microprocessor (preferably an ARM Cortex-M4 core MCU in this embodiment) to execute control logic. A surge protector (compliant with IEC 61643-11 standard) is connected to the mains power input to suppress overvoltage. The temperature control device includes an exhaust device (preferably a DC axial fan in this embodiment) and a heating device (preferably a PTC heater in this embodiment). The power of the heating device can be selected according to the chassis volume, with a preferred range of 100W to 500W. This is based on the size of a typical traffic chassis (approximately 0.5m³) and climate data to ensure effective temperature control in ambient temperatures ranging from -20°C to 50°C.

[0055] It should be further explained that the functions and features of the modular intelligent traffic control chassis provided by this invention include: 1. This chassis is a hybrid design that combines dual-unit and single-unit configurations. When used in dual-unit configurations, they are connected as one unit via the integrated "Cable Storage Box 3" at the bottom. Different electrical devices can be configured in each chassis, and the two chassis can be interconnected through the "Cable Storage Box 3" for flexible wiring. When used in single-unit configurations, only the "Cable Storage Box 3" at the bottom of the single unit needs to be configured, which is convenient and flexible.

[0056] 2. When used as a dual-body chassis, the chassis door opens from the center to the left and right, which is convenient for on-site construction, maintenance and repair, and is also aesthetically pleasing.

[0057] 3. The chassis can be customized according to customer needs, using ordinary steel plate with powder coating or 304 stainless steel.

[0058] 4. Each chassis has a bottom cable entry design for rodent and moisture protection, improving equipment reliability and lifespan. Specifically, to achieve rodent and moisture protection, multiple cable entry holes are pre-set on the bottom of the chassis, and each cable entry hole is equipped with a double-sided protective coil. Cables pass through the protective coil into the chassis. This structure effectively seals the holes, preventing small animals from entering and moisture from intruding. Furthermore, multiple circular cable entry holes are pre-stamped into the chassis base plate (usually made of galvanized steel or stainless steel). The diameter of the holes (preferably standard sizes such as 20mm, 25mm, and 32mm) should be slightly smaller than the outer diameter of the selected cable guard coil in its natural state to ensure an interference fit. The edges of the holes need to be deburred and bent to form a slight flange structure to increase strength and prevent sharp edges from scratching the cable or cable guard coil; Furthermore, the double-sided protective coil is preferably made of silicone rubber or neoprene rubber. Silicone rubber is chosen because it has excellent high and low temperature resistance (-60°C to 200°C), superior aging resistance, and durable elasticity, enabling it to adapt to harsh outdoor environmental changes. The protective coil has an "I"-shaped or double-lipped structure, with the following specific features: ① Outer edge fixing lip: A raised fixing lip is designed on the outer side of the coil guard. During installation, this fixing lip is squeezed and extends beyond the thickness of the chassis bottom plate, using the elastic rebound of the material to tightly fasten to the edge of the cable inlet hole, forming the first mechanical fixation and seal; ② Central Slit: The central area of ​​the cable sheath has one or more slits (preferably two intersecting in a cross shape). These slits are closed under normal conditions, effectively preventing moisture and insects from entering. Their length and shape are carefully designed to ensure that they are evenly spread out when the cable passes through, and to generate a continuous clamping force on the cable sheath; ③ Inner sealing lip: The inner side of the slit, that is, the part that directly contacts the cable, is designed with at least one inwardly protruding sealing lip (or "cable lip"). When the cable passes through, this sealing lip undergoes elastic deformation and adheres tightly to the irregular surface of the cable, forming the most critical second dynamic seal, effectively preventing moisture (capillary action) crawling along the cable surface and tiny insects from entering.

[0059] Understandably, during installation, the first step is to select the appropriate coil size based on the cable diameter. Then, align the outer edge of the coil's retaining lip with the cable inlet hole on the chassis bottom plate. Use a specialized installation tool or manually press firmly to cause the retaining lip to elastically deform and slide past the hole edge, ultimately locking into the predetermined position. At this point, the interference fit between the outer edge of the coil and the metal hole wall generates strong radial pressure, achieving a static seal between the coil and the chassis. Subsequently, the cable is passed from the outside of the chassis into the narrow slit in the center of the coil. The slit is opened by the cable, and the inner sealing lip tightly wraps around the cable sheath. Due to the elasticity of the rubber, the sealing lip applies a continuous and uniform confining pressure to the cable. This pressure is sufficient to disrupt the path of moisture intrusion along the cable surface, thus achieving a dynamic seal between the coil and the cable. This double-sided (facing the chassis and facing the cables) sealing structure together constitutes a reliable sealing system. The rodent-proof capability of this design is based on two points: first, the silicone rubber material used in the cable guard has a certain hardness (e.g., Shore A hardness between 50-60), making it difficult for small rodents to bite through; second, after installation, the cable guard completely fills the gap between the cable and the inlet hole, eliminating any gaps that rodents can gnaw or crawl into. Static sealing is achieved through a pre-drilled hole interference fit, and dynamic sealing is achieved through an elastic slit and inner sealing lip. This dual protection ensures excellent moisture-proof (anti-condensation, anti-splash) and rodent-proof effects. Its modular (specification-based) design allows for flexible selection based on the number and diameter of cables on-site, simplifies installation, eliminates the need for additional sealant, avoids the problem of sealant aging and failure, and significantly improves the long-term reliability of the traffic control modular intelligent chassis in complex outdoor environments.

[0060] 5. All side doors of the chassis are made of engineering PVC material and have installation positions for the wireless communication antennas of each device, preventing external antenna placement and potential damage. Specifically, the chassis has side doors on both the left and right sides, made of engineering PVC material. The inside of the side doors has pre-drilled installation space and fixing holes for internal wireless communication antennas, preventing damage caused by external antenna placement. Additionally, manual operation buttons can be installed on the side doors for easy operation of the equipment inside the chassis (such as signal controllers) by on-site personnel. This allows on-duty police officers to easily operate the equipment without opening the front and rear chassis doors. For example, if the chassis contains a road traffic signal controller, officers can use the manual buttons inside the side doors to control green lights in different directions.

[0061] 6. Each chassis has a small door and interface for generator or external power input on the side bottom.

[0062] In a preferred embodiment, this application also provides an electronic device, the electronic device comprising: The computer device includes a memory and a processor, wherein the memory stores computer-readable instructions that, when executed by the processor, implement the control method of the traffic control modular intelligent chassis. The computer device can be broadly categorized as a server, terminal, or any other electronic device with the necessary computing and / or processing capabilities. In one embodiment, the computer device may include a processor, memory, network interface, communication interface, etc., connected via a system bus. The processor of the computer device can be used to provide the necessary computing, processing, and / or control capabilities.
