According to incomplete statistics, the social ownership of electric bicycles in my country has exceeded 250 million in 2018, and it has become one of the most widely used road vehicles. Electric bicycles are convenient and inexpensive to ride, but they also cause a lot of road traffic safety problems. According to the World Health Organization, 50% of road traffic accidents are caused by electric bicycles. In addition, the theft of electric bicycles, violations of regulations, and difficulties in management have also posed challenges to public security management.
In April of this year, the new national standard policy of “Electric Bicycle Safety Technical Specifications” was officially implemented, which is intended to increase the regulation and control of electric vehicles. As early as a few years ago, many cities have used the Internet of Things technology to carry out the prevention and control of local electric bicycles. With the launch of the “new national standard” boots, it is believed that more and more cities will speed up the regulation and use of electric bicycles, and this will further promote the deeper and wider application of the Internet of Things technology.
Currently, there are mainly two Internet of Things electric bicycle management solutions on the market, one is based on active RFID technology, and the other is based on NB-I0T technology.
1. Active RFID electric vehicle system management plan
The Internet of Things electric bicycle prevention and control management system solution developed based on RFID technology integrates RFID automatic identification, Internet of Things perception, GIS, cloud technology and mobile Internet technology to realize real-time automatic identification, positioning and tracking of urban electric vehicles, and alarm distribution The comprehensive application processing capabilities of mobile search and mobile search can improve the efficiency of case processing, solve the case, prevent theft from happening, and create a harmonious social environment.
1.1 Public security registration and real-time monitoring function
The system can meet the needs of the public security department to manage the licensing and travel information of electric bicycles. Using RFID technology, RFID base stations, including fixed base stations, mobile base stations, etc., are deployed at traffic intersections, prosperous commercial blocks, and key road sections of major arterial roads in urban areas. At the same time, after installing anti-theft electronic license plates with RFID electronic tags on electric bicycles, the public security management department can use the system to register vehicle information, owner information, etc., to achieve one person, one vehicle, one license, and real name system for electric bicycles. By reading the RFID electronic tags of each passing electric bicycle within the coverage of the base station, and sending it to the public security data platform, it records the travel information of the electric bicycle in real time, helping the public security management department to realize 24/7 monitoring of the licensed vehicles.
1.2 Functions for preventing theft and improving case handling efficiency
By installing the owner’s APP and using the Internet of Things electric bicycle prevention and control management system, electric bicycle owners can grasp the dynamics of the vehicle in real time, query and playback the historical trajectory of the vehicle operation. Once a vehicle is stolen, it can be reported directly through the App with one button. After receiving the alarm information, the system captures and analyzes the location information of vehicles within the coverage area of the base station, and sends it to the public security platform. The platform immediately tracks the vehicle’s trajectory and locks the area where the stolen vehicle is located, through the mobile base station Search for the RFID signal of the vehicle to retrieve the stolen vehicle, provide more accurate and effective technical support for the public security department, realize the detection of theft cases, and help the vehicle owner recover losses.
In addition, with the help of the Internet of Things electric bicycle prevention and control management system, criminals who use electric bicycles as a means of transportation can be effectively tracked and monitored, which is conducive to arrest.
2. NB-IoT electric bicycle prevention and control management system solution
NB-IoT Narrow Band Internet of Things (NB-IoT) is an important branch of the Internet of Everything.
The NB-IoT electric bicycle prevention and control management system solution uses wide-area Internet of Things, cloud computing, big data, GIS, satellite positioning, NB-IoT communication and other technologies to realize real-time monitoring of electric vehicles and use electric vehicles for social security management And traffic management big data analysis is the core, so as to improve the comprehensive urban governance, social security management and urban smart traffic management.
2.1 Vehicle positioning and data collection functions based on NB-IoT
The system uses satellite signals (GPS/Beidou) to obtain positioning data, and transmits the positioning data to the cloud server platform through the NB-IoT telecommunication network to realize the positioning of electric vehicles. The system installs the license plate and NB-IoT tracker on the electric vehicle, and binds it with the owner’s vehicle information, owner information, license plate number and other information. The vehicle obtains real-time satellite positioning data and uploads it through the NB-IoT mobile network. It realizes real-time collection of information such as location, distance, speed, and time of the vehicle, and has functions such as vibration warning, displacement warning, and power failure warning.
2.2 Intelligent chapter correction and tracking deployment control function
Through the satellite positioning system and mobile network, it is possible to conduct targeted violation control at major intersections and elevated locations. Based on electric vehicle dynamic traffic big data, such as vehicle location, speed, running trajectory, road condition data and other multi-dimensional research and judgment, real-time detection of red light running, elevated, retrograde, illegal parking and other violations, so as to effectively channel traffic and control electric vehicles To manage.
3. Comparison of active RFID and NB-IoT technology solutions
First, positioning function: It is an important function of the Internet of Things electric vehicle management and control system. Under normal circumstances, the positioning of NB-IoT technology is achieved by satellite signals (GPS/Beidou), so the continuity of positioning can be better than that of active RFID, and the displayed driving trajectory will be better. However, satellite signals are used. If the vehicle is in an underground garage, in a residential area, closed streets, bad weather, etc., weak or no satellite signals may result in large positioning errors or inability to locate the vehicle, resulting in the vehicle being unable to be found. . Active RFID technology is not affected by weather and environment.
Second, in terms of installation: The active RFID electronic tag is small and does not require an external power supply. It can be installed at any position in the vehicle. It has good concealment and is not easy to find. When there is no fixed base station coverage, a handheld mobile base station can be used to search. The NB-IoT terminal is large in size and needs to be connected to the power supply of the electric vehicle. Therefore, the installation location is limited. Generally, it can only be installed in the headlight or the rear of the vehicle. Once the vehicle is stolen, the thief can easily follow the power cord. The locating terminal was found and disassembled, resulting in the stolen vehicle not being recovered.
Third, in terms of cost: the cost of NB-IoT technology is about 3 times higher than the cost of active RFID technology based on the equipment cost of the equipment required for the implementation of the entire project; Technically, the data of each vehicle is communicated through the network of the telecom operator, and each vehicle owner also needs to bear the corresponding traffic fee.
Fourth, in terms of data collection: Compared with active RFID technology, NB-IoT can not only collect vehicle location data, but also collect vehicle speed, driving direction, and dynamic traffic data. It is more advantageous in terms of dimensions.
Fifth, from the perspective of technological extension: Since the active RFID system is based on a comprehensive system of intelligent city IoT perception of millions of users, it has very good scalability. The base station deployed in the early stage can form a seamless coverage of the entire city’s information perception network, including sanitation worker sign-in management, road inspection management, bus station reporting management, power grid inspection management, pet management, police patrol management, and elderly anti-lost management Positioning management, student street positioning, etc., to create a new generation of smart city management system.
In a comprehensive comparison, the active RFID technology solution is more practical in the management of electric bicycles. Of course, if you have ample budget, you can also consider using a combination of the two technologies to give full play to their respective advantages, which can provide a better experience while also taking into account practicality.
