Innovative Development and Application Analysis of Vehicle Security Inspection System in Public Security Inspection Stations

The public security inspection station bears the heavy responsibility of vehicle safety inspection and road traffic safety guarantee. Public security checkpoints are also an important component of the social security prevention and control system, and an important defense line for building a safe city. However, the current level of informationization at domestic inspection stations is generally low, and there is an urgent need to improve the application level of technological informationization in order to assist the traffic safety management department in carrying out vehicle security inspections. Therefore, combining advanced technologies such as big data and artificial intelligence to create diversified, intelligent, and automated smart public security checkpoints has become inevitable.



Diversified demand for security equipment at public security inspection stations

Public security checkpoints are an important barrier to consolidate the outskirts of cities and effectively prevent and filter out various risks. They are a key pivot in the social security prevention and control checkpoint system, as well as an important channel to respond to the crackdown on various crimes in urban areas and a fortress to enhance prevention and control capabilities. Improving the technology and information technology application level and security inspection and control capabilities of highway public security checkpoints, achieving comprehensive, fast, and efficient collection, input, comparison, and upload of relevant information, fully leveraging the filtering and barrier role of checkpoints, is of great significance for promoting the construction of safe cities, serving the national anti-terrorism strategy, and maintaining social stability.

In recent years, the Ministry of Public Security has issued a series of documents, including the "Guiding Opinions on Strengthening the Construction of Highway Public Security Inspection Stations", to promote the construction of public security inspection stations. It is required that all regions "must incorporate the strengthening of highway security control into the social security prevention and control system and vigorously promote the construction", "adhere to the work principles of focusing on the overall anti-terrorism situation, strengthening technological innovation, improving information methods, strengthening information integration, analysis, and promotion, and improving service efficiency".



The demand for vehicle security inspection equipment at public security checkpoints is mainly reflected in two aspects: technology and form.

From a technical perspective, over the years, the security inspection technology of public security checkpoints has been continuously improving and developing. Especially in recent years, with the mature development of big data and artificial intelligence technology, big data and artificial intelligence have begun to be widely applied in vehicle security inspection. License plate recognition, face recognition, facial recognition, and big data comparison technology have been continuously integrated into vehicle security inspection systems and equipment. Due to the support and promotion of artificial intelligence technology, the vehicle security inspection equipment at public security checkpoints is showing a strong trend of intelligent and intelligent development.

Innovative Development and Application Analysis of Vehicle Security Inspection System in Public Security Inspection Stations
From a morphological perspective, the form of vehicle security inspection equipment at public security checkpoints has also begun to show a trend of differentiation and diversification. As is well known, in the past, the vehicle security equipment at public security checkpoints was mostly fixed equipment. Vehicle security inspection equipment is often a government procurement project, and the investment and construction of the project, from planning, project approval, funding, to bidding, construction, acceptance, audit, and so on, involves multiple departments and links, with long construction cycles and large investment. Any obstruction in any link will affect the project progress or even fail.

Sometimes, there are special application requirements in practical applications, where the demand for vehicle security equipment is not fixed but temporary, such as vehicle security checks at important meetings, large-scale events, and other security sites. As soon as the activity ends, the security equipment will be removed. If fixed equipment is also chosen, it will not only be troublesome but also cause unnecessary cost waste.



In practical applications, many vehicle security checks are not a normal mechanism, but are only implemented specifically during special periods or major security activities. In this situation, the utilization rate of vehicle security inspection equipment is not high. Therefore, if fixed security inspection equipment and systems are used, it is actually unnecessary. In addition, the fixed security inspection system is often unable to adjust, expand or change according to the actual application requirements, let alone system (data) fusion, such as temporarily increasing temperature measurement (such as the special needs of the COVID-19 epidemic prevention and control), or changing between vehicle inspection, human inspection, and people and vehicles at the same time. This has given rise to the demand for mobile and detachable security equipment in the market.

Therefore, in recent years, the market for vehicle security inspection equipment at public security inspection stations has shown diversified demands, including both traditional equipment and intelligent equipment; There are both fixed and mobile devices.

The advantages of intelligent security check from the perspective of lane rapid security check system

Smart security check is the development trend of vehicle security check systems at public security checkpoints. Smart security check integrates AI and other technologies, giving the security check system a "super brain". It not only enriches the experience of intelligent application scenarios for vehicle security check, but also greatly enriches the connotation of vehicle security check systems.

The traditional method of conducting security checks on passing people and vehicles in the past could only be done manually, where on duty police officers stopped parked vehicles based on experience and required drivers and passengers to present valid identification documents such as ID cards and driver's licenses for identity verification. This not only has low efficiency, but also causes inconvenience and inconvenience to the public, and even affects the public image of law enforcement departments in a harmonious society.

With the rapid development of the economy, the number of cars in China continues to grow, and people's tourism and travel activities are becoming increasingly frequent. As a public security checkpoint, the daily traffic volume of passing vehicles is rapidly increasing, bringing enormous pressure to vehicle security checks. Faced with the increasing pressure of car ownership, traditional security equipment and systems are no longer able to meet the needs of modern vehicle security checks, especially when applied to vehicle security checks at public security checkpoints. The shortcomings of traditional security equipment and systems are even more prominent. Relying on limited police force and random inspections can only be a drop in the bucket, and cannot achieve the expected goals of security checks and the needs of security and stability maintenance. Meanwhile, using traditional methods, it takes an average of 2-3 minutes for each vehicle to undergo security checks, which can lead to vehicle congestion at any time due to the frequency and duration of security checks. Ensuring the safety of vehicle traffic while also avoiding road traffic congestion is the dominant idea of public security checkpoints, which has given rise to the demand for intelligent security checks.

To meet this demand, researchers have actively explored and developed a fast and intelligent security inspection system.

Compared to traditional security equipment and systems, intelligent security systems have significant advantages. Traditional security inspection equipment and systems often have low efficiency and slow detection speed. Sometimes, only spot checks can be used to cope with the pressure of security checks. The rapid and intelligent security inspection system has effectively solved this industry pain point.

The rapid intelligent security system adopts an unmanned approach to conduct comprehensive and all-weather automatic detection of vehicles and passengers. The system automatically guides vehicles into the detection area. After the system completes the detection, normal vehicles can leave the detection area. In case of abnormal vehicles or personnel, the system will automatically sound an alarm and intercept the vehicles. At the same time, the alarm information will be transmitted to the police duty room, and the on duty police will quickly arrive at the alarm scene for processing.

The rapid intelligent security inspection system integrates functions such as vehicle license plate information collection and recognition, personnel facial image information collection and recognition, vehicle chassis information collection, number of personnel in the vehicle information detection, vehicle window movement detection, facial image information comparison, vehicle license plate information comparison, vehicle interception and stopping, vehicle guidance, abnormal data information alarm display, and "one inspection" identity verification terminal re inspection. It truly realizes the automatic security inspection of small motor vehicles and passengers in all directions after passing by, including leaving face for people, leaving license plates for vehicles, leaving bottom for vehicles, linking people and vehicles, and one vehicle and one gear. And by comprehensively utilizing advanced technologies such as machine recognition, big data, and system integration, we truly achieve comprehensive, all-weather, and normalized automatic detection and effective warning of transit personnel and vehicles.

The lane rapid security check system can be divided into sliding window mode and non sliding window mode, and F1 (fishbone) security check or straight path security check can be selected according to the site conditions. Among them, the straight lane security check can also choose non-stop security check (medium and low speed) and parking security check (<10 seconds) as needed.

The lane rapid security check system greatly improves the efficiency of security checks and the speed of vehicle traffic through intelligent diversion. Vehicles can pass through the check quickly in 20 seconds, basically achieving a mandatory check for vehicles. In terms of personnel inspection, the inspection station has installed cameras in important areas such as the security inspection hall and non motorized vehicle lanes to quickly detect suspicious situations and issue real-time alarms. The intelligent application of the lane rapid security inspection system greatly reduces the workload of security personnel and improves security inspection efficiency.

The lane rapid security check system also integrates the terahertz human body security check system for personnel. Inspected personnel only need to walk through the security check channel, and the system can automatically recognize the metal, liquid, plastic, ceramic and other items on the inspected personnel's body, and display them in real time to the client, thereby achieving no perception, no stop, and no touch security check, replacing the traditional contact based body search mode, and avoiding the discomfort of forcing the public to cooperate with the certificate taking security check. At the same time, in order to cooperate with human security checks, the inspection station has installed cameras in important areas such as the security inspection hall and non motorized vehicle lanes. Suspected individuals can be quickly identified and compared through facial recognition, license plate recognition, and mobile phone serial code recognition. Once suspicious individuals are detected, the system will alarm in real time, achieving precise strikes.

As of now, the lane rapid security inspection system has been widely used in Shanghai Shenhai Inspection Station (G15 Expressway) and other places. At the Shanghai Shenhai Inspection Station (G15 Expressway), our company's F1 rapid security inspection model has pioneered the industry nationwide, receiving praise from users and media attention.

The lane rapid security inspection system has accelerated the transformation of public security checkpoints from traditional manual service mode to "intelligent service and intelligent service" mode, reducing the police force invested in public security checkpoints by half and doubling inspection efficiency.

Mobile security inspection combination device, making security inspection application scenarios more diverse

To solve the problems of high site requirements, high overall investment, long construction period, complex financial approval, long-term maintenance in the later stage, and generally low utilization rate of fixed smart security inspection systems. We have actively explored using our own technology. In response to the large demand feedback and application requirements of public security users in various regions, engineering and technical personnel have developed an innovative security inspection device called "Guanlian" mobile security inspection combination device, which is movable and easy to disassemble and assemble. The system can construct temporary movable security checkpoints in locations that are not suitable for constructing fixed checkpoints, which can be deployed anytime, anywhere, quickly, and installed and used immediately. When there is a security inspection task requirement, several standard module assemblies can be shipped to the site and quickly assembled into a frame to form a standard security inspection parking space and put into use. After the security inspection task is completed, several standard module assemblies can be quickly disassembled and stored for shipment. According to the needs of security inspection tasks, the system can use different assembly modes in segments (such as only inspecting people) or whole segments (such as inspecting vehicles). A folding canopy can be installed at the upper end of the frame, which can provide both rain and shade to prevent affecting the video or facial capture effect. If security checks are carried out on passing personnel, only the front device needs to be installed and equipped with two facial recognition channel gates.

The processes of vehicle guidance, information collection and comparison, alarm, and gate opening and closing are all automated, and unmanned automatic security inspection mode can be achieved; Detailed inspection can read the second-generation license and driver's license, and the communication transmission between the system and the public security platform can use 5G communication method.

The mobile security inspection combination device is designed based on the principles of flexibility and practicality. All components of the system are standardized, and the data and power cables are preset and embedded in the pipe slot. The cable connection adopts aviation connectors, which are quick to plug and unplug, waterproof and dustproof. All pipe slots are spliced with locking buckles, without the need for additional screws. Two people can complete the assembly and joint debugging in less than an hour. The base weighs about 40KG and is fixed and supported with the bottom cable trough through the I-shaped lock buckle, providing a certain degree of stability and resistance to strong winds. The base serves as the transfer center for the upper, lower, left, and right power and data cables.

The four major advantages of the system

1. Effectiveness: Comprehensively reflecting the three major functional goals of "fast passage, reducing burden and increasing efficiency, and benefiting the people", truly practicing the guiding spirit of the Ministry of Public Security's leadership to "build smart public security, demand police force from technology, and seek practical results through innovation", achieving comprehensive, all-weather, and normalized security checks for people and vehicles, as well as data-driven management of "one person, one file, one vehicle, one file";

2. Scalability: All equipment models involved in the rapid security inspection system can be selected, combined, added or replaced as needed to meet the requirements of different task objectives, environmental conditions, and police mechanisms;

Through the 5G network, it is possible to connect with the backend database, ensuring compatibility and stable and reliable operation of the system;

4. Convenience: When there is a security inspection task requirement, the module components can be quickly and conveniently assembled and put into use. After the security inspection task is completed, it can be easily disassembled and stored in the warehouse. The disassembly and assembly of brackets, insertion and removal of cables, information collection, and loading and unloading of control devices are very convenient, without the need for professional knowledge, and the entire equipment can be disassembled and assembled within one hour. All device accessories can be transported in a small van.
