Electric vehicles can be seen everywhere in people's lives. They not only facilitate people's travel and relieve traffic pressure, but also are low-carbon, environmentally friendly, and resource-saving, making them a part of green transportation. However, the phenomenon of electric vehicle theft has also become one of the increasingly common theft crimes in society. Almost everyone has experienced vehicle theft, and people urgently hope for a way to curb and reduce these behaviors.
1、 Social background
The rampant phenomenon of car theft has become a major issue in social security
The product characteristics of electric vehicles make them easy to steal and sell;
About 25% of car owners have experienced vehicle theft;
Frequent theft cases of electric bicycles
Electric bicycles are easy to steal and sell, difficult to identify, and have high value, making them easy targets for thieves;
Due to low technological content and lack of effective anti-theft products, the theft rate of electric bicycles remains high;
The theft of electric bicycles is currently the most reported case by the public security department, but the detection rate is extremely low.
The public security department is under great pressure to solve cases
Electric bicycle theft has a short crime time, fast transfer, and enormous pressure to solve the case;
The daily occurrence of electric bicycle theft cases is high, and the high number of reported cases affects the detection rate;
The public security department lacks effective measures and means to crack down on the theft of electric vehicles, which has caused dissatisfaction among citizens.
2、 Feasibility analysis of electric vehicle positioning monitoring
In this social context, intelligent anti-theft services for electric bicycles based on positioning technology and the Internet of Things have emerged in response to this demand. Introducing the concepts of human vehicle interaction and communication interaction, facing the short-term theft and transfer of vehicles by criminals, using satellite and base station positioning technology to continuously locate and track to assist the police in accelerating case solving
We have applied advanced wireless communication technology and positioning technology to the location services of personnel and vehicles, and launched a positioning, anti-theft and tracking terminal product suitable for electric bicycles. It allows car owners to establish a 1-on-1 authentication relationship with the anti-theft device through their mobile phones, record the real-time status of the vehicle at any time, and send the location and information to the car owner's mobile phone as soon as possible in case of theft. It supports abnormal vibration and displacement alarms of the vehicle, and can achieve positioning and tracking no matter where the vehicle is placed
3、 Overview of Electric Vehicle Monitoring System Solution
The entire electric vehicle safety monitoring software consists of a backend monitoring system and an onboard terminal.
The backend monitoring software is located in the "nerve center" of the entire system, centrally implementing monitoring, scheduling, alarm response, and other information services, and coordinating and managing the hardware of the entire system, including statistical analysis of data.
The car terminal is a compact and professional intelligent control terminal suitable for installation on electric motorcycles. The terminal adopts large-scale integrated circuits, with fully built-in antennas. Each functional module and the whole machine have undergone multiple tests, and the embedded software with a modular multi-layer structure ensures stable and reliable performance of the terminal device. And there are terminal products designed with non functional features for different types of electric vehicles to meet the needs of different devices.
Advantages of electric vehicle terminals:
1. The appearance is atmospheric, the volume is compact (with a thickness as low as 15mm), and the concealment is strong.
2. Wide voltage design (9-90V) ensures the safety and stability of equipment.
3. GPS+LBS dual positioning eliminates the worry of no signal when arriving at an underground parking lot, providing more accurate positioning.
4. Module high integration design, using large-scale integrated circuits, module high integration, high technical content.
5. The wiring is simple, with only positive and negative wires, and even girls can install it themselves.
6. Intelligent power management, ultra-low power consumption, intelligent sleep and wake-up, sleep current less than 15mA.
7. Computers and mobile phones can check cars at any time, making it convenient and intelligent. "People" and "cars" have zero distance and zero fees to receive alarm reminders.
The data transmission between the vehicle terminal and the monitoring center is carried out through the GPRS/GSM public data network. As long as the GSM can cover the area, the system can operate stably
4、 Function analysis of monitoring platform
The positioning and monitoring system of this electric vehicle is designed to minimize costs while ensuring optimal performance, pursuing the maximization of cost-effectiveness. The software system is developed independently, which facilitates long-term cooperation and ensures the economy and practicality of the software system.
1. Remote power outage: When a vehicle is stolen or robbed, users can remotely operate the vehicle by sending SMS commands through their mobile phones to achieve power outage function.
2. Battery anti disassembly alarm: When criminals remove the vehicle battery, the system will issue a GPS power-off alarm, and the system will call the designated phone through GPRS
3. Send an alarm message: Vehicle illegal power outage alarm.
4. Electronic fence alarm: It can set a designated area for the vehicle. When the vehicle exceeds the designated area, the device will automatically alarm and send a text message.
5. Real time vehicle positioning: Real time monitoring of vehicle location can be achieved through GPS satellite positioning and GSM network communication.
6. Historical trajectory query: It can query the vehicle's travel route, parking time, and speed in detail during the historical time period, and can export them to form a report.
7. Vehicle vibration and displacement alarm: After the vehicle vibration and displacement alarm is set up, a message will be automatically sent to the bundled mobile phone when the vehicle vibrates.
8. Safety reminder: speeding reminder, dangerous road section reminder, etc.
9. Safety monitoring: vibration alarm, fence setting, oil and power outage, etc.
10. Common standard functions: remote settings, issuing commands, calling, scheduling, alarm, etc.
11. Real time information query: The current vehicle location information, speed, driving direction, and alarm status can be queried through the background and mobile phone.
