As shown in Figure 2, the early warning prompt module includes an infrared pyroelectric sensor and a vibration sensor. The infrared pyroelectric sensor is used to monitor the infrared signal of the surrounding object activities and transmits the infrared signal to the main control module; There is continuous vibration, and if there is continuous vibration, a vibration signal is sent to the main control module.

As shown in Figure 3, the tamper alarm module includes a tamper switch and an audible and visual alarm. When the tamper switch is triggered, an alarm signal is sent to the main control module, and the audible and visual alarm is triggered at the same time. Sound and light for warning.

The GPS module is used to locate the current position of the electric vehicle, and send the positioning information to the main control module.

The main control module judges the current warning level according to the received infrared signal, vibration signal and alarm signal, and sends the warning level information and positioning information to the mobile terminal through the NB-IOT module; the main control module is also connected to the electric The battery of the car is used to send the battery power information and battery charge and discharge status information to the mobile terminal through the NB-IOT module; the mobile terminal is used to receive the warning level in real time, check the electric vehicle location and electric vehicle power information online, and You can manually reset the current warning level and manually turn off the sound and light alarm.

Sound and light alarm includes tweeter and LED lights.

The warning level includes four levels of "normal", "general", "dangerous" and "very dangerous". When the main control module does not receive an infrared signal, a vibration signal or an alarm signal, it judges that the current warning level is "normal" and passes The NB-IOT module sends it to the mobile terminal; when the main control module only receives the infrared signal, it judges that the current warning level is "general" and sends it to the mobile terminal through the NB-IOT module; when the main control module receives the infrared signal at the same time When the infrared signal and vibration signal are detected, the current warning level is judged to be "dangerous" and sent to the mobile terminal through the NB-IOT module; when the main control module receives the infrared signal, vibration signal and alarm signal at the same time, the current warning level is judged to be "Very dangerous" and sent to the mobile terminal through the NB-IOT module.

When the warning signal is upgraded to "general", it means that there are creatures approaching the electric vehicle, and when the warning signal is further upgraded to "dangerous", the electric vehicle is being moved, and when the highest level "very dangerous" signal is sent to When moving the terminal, it indicates that the battery of the electric vehicle or the electric vehicle is being disassembled by the thief.

The mobile terminal can also remotely control and power off the power supply of the electric vehicle through the NB-IOT communication module.

A specific embodiment of the NB-IOT-based electric vehicle anti-theft system of the present invention is as follows:

The system is installed on the electric vehicle, and the main control module collects the battery status information and GPS positioning information of the electric vehicle in real time, and transmits the battery status information and GPS positioning information to the mobile terminal in real time through the NB-IOT communication module. View the location, battery level, and other status of your electric vehicle. When there is no activity around the electric vehicle, the infrared pyroelectric sensor cannot detect the infrared signal. At this time, the main control module judges that the current warning level is "normal" and transmits the warning level to the remote mobile terminal through the NB-IOT communication module. The terminal shows that the current warning level is in the "normal" state. When there are people or animals around the electric vehicle, the infrared pyroelectric sensor can detect the infrared signal. If the main control module only receives the infrared signal, the main control module will judge the current warning level as "normal" and pass the warning level to NB - The IOT communication module transmits to the remote mobile terminal, and the mobile terminal displays that the current warning level is in the "general" state, because at this time, the infrared pyroelectric sensor may have detected ordinary passers-by or small animals around the electric vehicle. If the infrared pyroelectric sensor can detect the infrared signal and the vibration sensor detects the vibration signal at the same time, it means that the electric vehicle is being moved at this time. The "dangerous" warning level is sent to the mobile terminal, and the mobile terminal displays that the current warning level is in a "dangerous" state. If a thief steals the battery of an electric vehicle, he will inevitably use violent means to dismantle the battery box. At this time, the anti-pry switch and the sound and light alarm composed of tweeters and LED lights will be triggered. At the same time, the infrared pyroelectric sensor The vibration sensor and the vibration sensor must be able to detect the infrared signal and the vibration signal respectively. At this time, the main control module receives the infrared signal, the vibration signal and the early warning signal at the same time, and the main control module passes the "very dangerous" early warning level through the NB-IOT communication module. - The IOT communication module sends it to the mobile terminal, and the mobile terminal displays that the current warning level is in a "very dangerous" state. According to the current warning level, mobile terminal users can choose solutions such as remotely powering off the power supply of the electric vehicle, rushing to the scene of the accident to check the situation, and directly calling the police on the mobile terminal. The GPS module on the user's mobile terminal You can check the location information of the electric vehicle at any time, which is very helpful for the first time positioning of the electric vehicle.
