On October 8, the Ministry of Public Security revised and issued the "Regulations on the Application and Use of Motor Vehicle Driving Licenses." It stipulates that other provisions shall be implemented on January 1, 2013, with the exception of those concerning the management of school bus drivers. Borrowing from the media's generalization, the new regulations are "more strict" and "more detailed" than before. The score has been increased from 38 to 52 items, and the “red light†has been increased from 3 points to 6 points. If the number plate has not been hoisted or has been intentionally blocked or defaced, the number plate has not been installed as required, 12 points have been recorded. . The new regulations are even more hot-spots for penalties for red lights – ranging from 6 to 12 points. Whether or not it is a red light is an e-policeman of a security guard. The electronic eye monitoring is the basis of the implementation of the traffic rules. Here we briefly discuss how the e-police has become a useful assistant for road monitoring.
The composition and application of the electronic police monitoring system With the continuous updating of technology and the increasing market demand, the function of the high-definition electronic police system is not limited to the capture of vehicles with red lights. It also includes the capture of vehicles that do not follow the road, and vehicles. Retrograde capture, vehicle pressure line capture, security bayonet, traffic flow and traffic incident detection, high-definition video recording and other functions have further realized the management of urban intersections.
The composition principle of the electronic police is an important part of urban traffic intelligence management. The electronic police judges accidents more accurately, captures more quickly, and can still work normally in dark and harsh environments; it regulates traffic safety, enhances safe driving awareness, eliminates The red light phenomenon and the crackdown on illegal and criminal activities are of great significance. For the driver, it can raise awareness of compliance, avoid accidents and protect personal safety. For traffic managers, it is a manifestation of “power to the police for science and technologyâ€, which can improve the level of law enforcement, and can make violations faster. The response can improve the quality of personnel, strengthen the traffic police management responsibility system, establish a long-term management mechanism, establish a civilized image of traffic management, and play an immeasurable role in reversing the passive situation of traffic management consumption and exhaustion. For society, it can ensure traffic safety, unimpeded traffic flow, maintain good traffic order and ensure the safety of people's lives and property, thus making traffic an artery for economic construction and having a profound impact on social development and people's daily lives.
The electronic police system has applied cutting-edge technologies such as CCD camera and video transmission technology, industrial control computers, optical fiber (wireless) network transmission technology, and MCU. The whole system consists of three parts: front-end equipment, transmission equipment and central equipment. The front-end equipment mainly includes CCD low-light high-definition color camera, industrial control computer, and red light signal processor; transmission equipment includes optical transceiver (or wireless network), telecommunication network, Exchanges, etc.; The center equipment mainly consists of network servers, PC workstations, printers and other equipment.
The video electronic police system is a local area network system. Each front-end electronic police station is a terminal in this network. In this local area network system, there is a workstation besides the server, which reads data and records workstations. The on-duty personnel of the monitoring and control center can read the photographs already taken by the front-end control host through the “integrated illegal background processing system†of the PC workstation, and the transmission of the local area network can be connected using the optical fiber system. The control host converts the electrical data signals into optical signals through optical fiber transmission equipment and transmits them to the control center via the optical fiber. The optical terminal of the control center then converts the optical signals into electrical signals and sends them to the PC workstation through the switch. If there is no fiber optic cable condition, you can use a wireless communication card to download to your laptop or read the illegal picture by moving the hard disk. PC workstations can also use the “Comprehensive Illegal Background Processing System†software to call the “vehicle management†and “drive†databases of the server, link the database, and transfer and synthesize the archived data of the illegal vehicles, and print illegal vehicle images through the workstation. .
The electronic police system is a high-tech integrated system integrating industrial automation control, virtual detection, fuzzy analysis, image recognition, industrial computer, communication, local area network and electronic camera technology. Among them, the blurring technology and the image recognition technology are a leap in application, making the performance of the “electronic police†best displayed.
The electronic police system uses a dedicated camera mounted above the driveway to perform video surveillance 24 hours a day. The system has two cameras, one is a panoramic camera and the other is a close-up camera. The two cameras capture the same lane at the same time. The vehicle then connects the red status signal of the lane to the capture control host to provide the electronic police system with a connection between the illegal vehicle and the red light status.
In the panoramic video screen, the entire illegal process of the illegal vehicles with red lights is captured in real time. There are three pictures of panoramas and close-ups. The first picture shows the red light signal sign opposite, and the vehicle does not pass through the parking line. Two pictures show the red light signal sign opposite, a panoramic picture of the illegal process of the vehicle crossing the parking line; the third picture shows the license plate number of the illegal vehicle). The three images reflect the entire process of illegally driving a red light vehicle, and then transmit the illegal vehicle's image to the control center via optical fiber or wireless network. The control center processes the uploaded pictures and stores them in the system server. In this way, the access system and the authorized terminal computer can query and deal with illegal information.
Electronic police capture: The continuous improvement of road monitoring assistant technology, the increasing market demand, the function of the high-definition electronic police system is not limited to the capture of the vehicle red light, it also includes the capture of the vehicle does not follow the road, the vehicle is retrograde The capture, the capture of vehicle pressure lines, security bayonet, traffic flow and traffic incident detection, high-definition video recording and other functions have further realized the management of urban intersections.
1, illegal red light capture:
The system can detect and photograph the illegal vehicles that go straight through the red light and turn left and right; if the vehicle does not follow the lane, it captures and shoots; it includes the right-hand lane left-right turn, right-turn lane straight and left turn, left-turn lane straight and right turn; Retrograde capture of the vehicle: Directly detects the reverse-traveling vehicle in the capture lane, and directly recognizes the license plate information of the vehicle. The capture of the vehicle pressure line directly detects the vehicle that captures the pressure line and directly identifies the vehicle's license plate information.
Red light electronic police system to achieve a specific 1) the use of dynamic video detection trigger technology, in the red light state, complete the red light vehicle capture and license plate recognition, accurately record and store violation of the vehicle's violation time, location, driving direction, red light time Length, red light moments past the parking line, illegal license plate pictures, and panoramic pictures.
2) The illegal images of the captured vehicles are a vehicle license plate close-up view and two consecutive vehicle violations. The captured vehicle's illegal images can clearly and completely record the vehicle models, body colors, and license plate numbers of the illegal vehicles.
3) The center recognizes the license plate of the illegal car captured, and the identified plate automatically generates the illegal license plate library for further processing and confirmation by the illegal handler.
4) The use of industrial-grade color cameras, high definition, low illumination, and good stability; the camera control technology developed independently by the company enables the capture of the camera to adapt to different weather and light environment effects, enabling the system to work 24 hours a day.
5) At night, LED lighting lights developed by the company are used as auxiliary light sources to capture the license plate number at night.
6) Under the condition of communication, the combination of hardware and software can automatically monitor the normal operation of the system. At the same time, the two methods of timing report and emergency report are used to report the situation to the remote command center so that the center duty personnel can monitor the normal operation of the system more conveniently and effectively.
2. Illegal image saving function:
The format of the saved image is JPEG format, and the image encoding complies with ISO/IEC 15444:2000. The picture information can be superimposed according to the user's requirements. The synthesized picture definition can meet the artificial determination of the number plate of the vehicle. The red signal in the picture will not appear white, halo and other color distortions, which will affect the artificial red signal signal. Judgment
3, security bayonet function:
The automatic registration of the license plate number is performed for the vehicles passing under the non-red light signal status, and records are stored. The record format can be selected according to the user's requirements to save 1 to 2 records, record information includes: test site name, lane direction, license plate number, license plate color, etc.;
4, traffic flow and traffic incident detection:
Including traffic flow statistics, average speed, lane occupancy rate, headway time detection; but also can analyze the driving status of vehicles in the road, and generate alarm information for traffic events (such as: abnormal parking), to facilitate the timely and accurate Get the road traffic information at the intersection;
5, high-definition video recording:
A 24-hour panoramic video recording of the inspection area with a video frame rate of 12fps clearly reflects the details of vehicle violations or accidents. In addition, the video is in the avi format, which can be played by Windows' own player. It is convenient for users to make follow-up visits to illegal events that occur at intersections, providing a strong basis for illegal punishment and criminal investigation.
6. Illegal recording of pictures to prevent tampering:
After the system captures all kinds of intersection illegalities and traffic incidents, in order to ensure the accuracy and authenticity of the records, the tamper-prevention function is implemented according to the latest requirements of the national standard GA/T496-2009. When the central management system receives the illegal record picture, it first checks through the tamper-proof module. If the picture has been changed, the system will generate prompt information. Only the certified picture can enter the next step;
7, running status monitoring function:
The system can automatically record the operation log of the front-end device, record the HD camera's working status, data transmission process, and fault information, and automatically transmit it to the designated data center. The fault information mainly includes: image failure (no image, image blurring ), video recording failures, etc.
Conclusion:
The construction of the "Electronic Police" system involves a wide range of areas. The response from the citizens, policies and regulations, management measures, and technical preparations, and the improper handling of any one of these links will cause irreversible effects. Therefore, we must adhere to the principle of prudence in the construction of the system. The establishment of policies and regulations, the rationalization of management processes, and technical preparations will be carried out at the same time. They will go hand in hand to ensure the normal operation of the system once it is put into use, and to effectively achieve the effect of improving traffic order. Only in this way can we get praise from all aspects of society.
