Shenzhen Baode Computer System Co., Ltd. - Solutions Division
1. Application Background In recent years, as the country has invested large sums of money in the construction of highway transportation infrastructure, the country’s road traffic network has continuously expanded, which has significantly upgraded the road traffic environment and conditions. On the other hand, with the economic development and the improvement of people’s living standards, the number of motor vehicles has increased rapidly. Statistics from the Ministry of Public Security show that as of the end of 2009, the number of motor vehicles in China had exceeded 186 million, and the number of motorists in the country was close to 200 million. Such a huge base of motor vehicles will undoubtedly greatly increase the workload of the traffic management department. It is based on this status quo that the intelligent road monitoring system called “Electronic Police†has emerged, which has greatly eased this problem.
The electronic police system is an electronic instrument system developed using advanced image processing technology, a new generation of information transmission technology, integrated control technology and intelligent management technology and other modern high-tech means. It is installed at the intersection of urban traffic and is 24 hours a day against illegal red lights. Take a picture. The system consists of controllers, vehicle detectors, and cameras. In order to ensure that the system continuously records the red light passing through intersections and speeding vehicles in an unfavorable and uninterrupted manner, it provides a strong basis for penalizing illegal motor vehicles. Various types of embedded industrial control computers independently researched and developed by Baode Group provide mature solutions for video electronic police. Due to its advantages of reasonable price and high reliability, it has been widely used in various intelligent road monitoring systems.
2. System Requirements Considering the special application environment, the intelligent monitoring system needs to be exposed to dust, high and low temperature, humidity, vibration, electromagnetic interference and other harsh environments, and it can operate stably for a long time without interruption. The use of a fanless, compact, low-power type, long-term uninterrupted industrial computer can achieve stable, reliable, long-time operation of the entire system. Based on Baode's embedded computer BOX-100 and the customized “electronic police†intelligent identification software, the system can achieve the following functions:
1. Overspeed detection 2. Overspeed capture 3. Red light detection and capture 4. License plate recognition
3. Solution In addition to capturing red lights or speeding vehicles, this program can also record and identify license plate numbers of passing vehicles, compare them with vehicle databases, real-time find suspicious vehicles, and have 24-hour automatic operation, high efficiency and reduction. Man-made interference factors in the law enforcement process. The system plays a significant role in ensuring traffic safety, standardizing driving awareness, curbing red lights, speeding and other violations, and cracking down on robbery vehicles. It is a new generation system that replaces traditional electronic police systems that use video storage and manual recognition technologies.
3.1 System Architecture Diagram
3.2 Solution Description The traffic light detection board can identify the traffic lights at intersections and pass the recognition results to the BOX-100 IPC through the serial port. According to the implementation environment, detection and identification of vehicles can select vehicle induction detection technology such as buried coil induction technology, radar positioning system technology, microwave detection technology, etc., which can sense the passing vehicles and pass them to the BOX-100 IPC through serial communication. .
The BOX-100 provides two sets of PCI slots for two external video capture cards. Each video capture card can be connected to a panoramic camera, three sets of close-up cameras, a set of north-south and east-west directions, to meet the monitoring needs of a single intersection. The camera's data is transmitted to the BOX-100 in real-time via the PCI slot via a video capture card. An intelligent program running on the BOX-100 determines whether the vehicle is wearing a red light, whether it is overspeeding, and whether it is driving in reverse, by analyzing the received traffic light detection signal and the vehicle detection serial signal. If the condition of violation of the red light is met at this time, a control command is issued to shoot the illegal vehicle, and compression, consolidation, storage, and finally transmission are performed.
The VGA-100 and DVI interfaces integrated in the BOX-100 can simultaneously connect two sets of interface display devices to facilitate technicians and system administrators to maintain and identify the system. A network interface enables real-time data transmission between the data and the back-end control center server. Built-in 1 CompactFlash card slot and a 2.5-inch hard disk card slot, you can easily build a variety of custom operating systems, can also achieve real-time data stored in the case of poor communication with the back-end control center server, for system security and stability Operation provides the hardware foundation. Baode embedded industrial control computer has good compatibility, can fully meet the needs of the control machine equipped with multiple data acquisition cards and image capture cards, to achieve the system image capture, compression, signal acquisition, control and other functions.

6, the future development trend of electronic police accompanied by China's ongoing urbanization, electronic police equipment has been ubiquitous, there is no doubt that as an important means of science and technology and an increasingly mature technology of traffic monitoring equipment (ie, electronic police) Under the proper supervision and guidance of relevant state departments, it has played an important role for China's economic growth. In the content of the "3111" demonstration city construction promoted by the Ministry of Public Security and the Ministry of Science and Technology, the electronic police and the security guards are all important components. In the next three to five years, the electronic police industry will surely usher in a bigger one. With opportunities for development, competition will also become increasingly fierce and the key to competition in technology and equipment. The future technological development is mainly reflected in two aspects. First, advanced technology such as video detection and intelligent analysis will be applied practically in the electronic police system. This will greatly enrich the functions of the electronic police system and the second is based on embedded operation. The products of the system will become mainstream, which will enable the electronic police system to be qualitatively improved in terms of stability. This is similar to the way the DVR has traveled in China.
