In recent years, battery cars/electric bicycles can be seen everywhere on the road. Compared with bicycles, it is easier and faster to save effort; compared with cars, it has freer and more environmentally friendly travel, not affected by traffic jams, and will not emit exhaust gas that pollutes the beauty of the city; and Compared with motorcycles, it is more suitable for the public and easier to operate. Electric vehicles with many advantages are very popular. Incidents of theft of battery cars have also occurred one after another, and the current regulations on battery car management are not perfect. Most electric cars are not registered and hard to retrieve after being stolen. It is also difficult to identify the owner of the seized stolen car. , The anti-theft management of electric vehicles urgently needs to be strengthened.
The common electric vehicle anti-theft device on the market is a remote anti-theft alarm, which is composed of a vehicle-mounted host and a handheld remote control transmitter. The alarm horn is installed on the vehicle-mounted host. The function of the remote control is mainly to fortify, disarm and activate the alarm function. A wireless remote control power switch. This type of alarm is the mainstream anti-theft product in the electric vehicle market. It has high sensitivity and an alarm sound of more than 100 decibels. It can basically meet the needs of ordinary electric vehicle users, but the false alarm rate of this type of device High, such as wind and thunder, children playing, etc., may trigger the alarm. This kind of noise pollution caused by false alarms is serious and disturbs the people. Therefore, most electric vehicle users do not turn on the anti-theft alarm device, which leads to some illegal activities. Molecules can take advantage, and the theft of electric vehicles is becoming more and more serious. This shows that traditional security products can no longer meet the needs of users.
Recently, GPS positioning anti-theft alarms have appeared in the market. This method has a high cost. If the government finances money, the investment is too large and it is not suitable for promotion. It has been reported that a city invested more than 10 million to install 50,000 electric bicycles for free. This cost-effectiveness is too low; and in the follow-up, it has to cooperate with operators and spend GPRS data charges every month. Compared with the use of Internet of Things technology, the “electric vehicle anti-theft management system” is technically mature enough, and the cost of an RFID anti-theft system is relatively cheap compared to the cost of electric vehicles or other valuables, and it is easy to be accepted by the masses, and its development prospects are very promising. broad. The RFID anti-theft filing solution launched by Shanghai Chaowei Electronic Technology Co., Ltd. has been piloted and promoted in Deqing County, Huzhou and Qingpu District, Shanghai. 50,000 electric bicycles and supporting equipment and system software have been installed, with a total of less than 1.1 million, cost-effective and effective Very high, which helps the public security system to solve the case.
Chaowei active electronic tags adopt advanced RFID ultra-low power consumption technology, which is durable, waterproof, and has a lifespan of more than 3 years. The internal has a unique RFID code, and the device status information is written in the chip, which is far away from the matching Chaowei Reader two-way communication.
The “Electric Vehicle Anti-theft Management System” consists of two parts. One is based on the community. A remote reader is installed at the entrance and exit of the community. The data collection and theft alarm of the electric bicycles at the entrance and exit are carried out by the security guards. . The second is to extend to every street and pavement, install Chaowei remote readers in intersections, large supermarket entrances, hospitals, vegetable markets and other areas with multiple people and vehicles, and coordinate with the social monitoring system, “3.20” project and “110” command The center is connected to the network, real-time comparison and recording of the operating status and trajectory information of electric vehicles in the society, providing more detailed clues for investigating and solving cases.
skills requirement:
useRFIDTechnology, including electronic tags, readers, and supporting computers and network equipment. Each monitoring point needs to be connected to the public security network. On the one hand, it can obtain shared vehicle data, and at the same time, it can compare stolen vehicles;
electronic label:
Each car is equipped with an active RFID electronic tag, which is installed on the electric bicycle; it can be installed directly when the new car is registered, and can be installed directly at the registration point; the tag ID is bound to the owner and vehicle information.
Readers, divided into fixed and handheld;
When the electric bicycle passes by, the fixed reader can obtain the electronic tag information and transmit the tag information to the service platform; the handheld reader is convenient for stolen vehicle inquiries, and the reader has a signal strength identification function. Quickly search and determine the location of the tag, and find the stolen vehicle in time.
The fixed reader is installed in the video surveillance area, and RFID is closely coordinated with the surveillance. When the car owner calls the police, the tag ID number is queried according to the owner’s information, and then the relevant video is inquired about the last lost area and time of the ID number, and the situation of the theft scene can be quickly locked; at the same time, the ID signal is obtained according to the fixed base station at the intersection, real-time Determine the current location of the stolen vehicle, mobilize the police to handle the attendance; the attending police carry a handheld reader, and download the relevant stolen vehicle information to the handheld terminal, and according to the real-time linkage with the system center to reach the designated area for vehicle search, through the handheld reader Search in the designated area. If a stolen vehicle is found, the handheld terminal will sound an alarm; at the same time, it can quickly locate the direction and distance according to the signal strength of the reader.
Operational effectiveness:
1) Improve manageability: dual-card association recognition, vehicle information system management, and real-name information system, greatly improving the manageability of bicycles.
2) Reduce management costs: Higher efficiency and more controllable bicycle anti-theft measures greatly reduce the probability of bicycle theft and improve the overall security level.
3) Collect vehicle information comprehensively, and change “traditional” management to “smart” management. The vehicle information collected and recorded by the on-board tag enables the electric vehicle to have an informatized identity and becomes an important object of the community police’s basic information collection, effectively strengthening the daily management of the electric vehicle.
4) Real-time monitoring of vehicle trajectory, changing “static” anti-theft to “dynamic” anti-theft. When an electric vehicle in an illegal state passes through the identification area, the alarm information is judged, and the public security police command system is connected in parallel to command the police to search in real time according to the movement trajectory; the public security monitoring system can also be linked to the public security monitoring system to capture the vehicle and obtain the image data of the driver. Provide clues for investigating and solving cases.
5) Effectively increase the vehicle safety factor and change the “limited” protection to “real-time” protection. The anti-theft system is also equipped with a portable handheld machine for police and security personnel to conduct dynamic inspections to detect whether there are suspicious vehicles around. When a suspicious target appears, the handheld monitor will give an alarm, and the security personnel can display the distance of the vehicle. Identify suspicious vehicles with features.
