Device sleep function: When the vehicle goes out of flame and exceeds the set sleep time (time, the host computer can be configured), the device will enter the sleep state until the next bus has data or low pulse signal, the device will be woken up. After judging that the vehicle is turned off, it is no longer a direct power off, but enters the sleep mode and periodically reports the device health message.

RTC time function: With RTC (real-time clock) function, it can provide accurate time and provide time stamps (such as driving behavior messages, collision messages, etc.) for various messages.

There are several ways to get the real-time clock, and you can correct it by sending instructions from the server.

Intercept function: It can remotely issue interception commands, so that the vehicle can not be fired next time to achieve anti-theft or disable purposes.

Switch lock function: It can remotely issue the unlock command to enable the vehicle to open the central lock remotely. It is possible to remotely issue a lockout command (first to judge the door and close the trunk) so that the vehicle can close the central lock.

Remote car search: The remote car search function is realized by the device to control and read the bus data. The remote car search system realizes the remote car search function by remotely controlling the headlights or speakers of the vehicle.

Remaining battery reading function: It can read the remaining battery capacity of most models.

GPS positioning function: support GPS function, and optimize GPS anti-jamming and antenna to achieve fast GPS positioning. The reporting interval of the terminal can be set through the network, and the positioning information is uploaded to the server, and the server performs various data applications according to the uploaded GPS message, such as a track, a location, an electronic fence, and the like.

Curve compensation function: Generally, we set the GPS interval to a fixed value of 10S, but when encountering a curve or a bridge, there will be a trajectory directly crossing the road or bridge hole at the display end, which makes the user experience worse. In order to balance the accuracy of the trajectory and the data flow, the GPS reporting interval uses a preset value when traveling in a straight line. When encountering a curve, the curve compensation technique is adopted to increase the reporting density of the GPS point, so that the display end is more Attach the road surface and enhance the user’s physical examination.

Low-voltage alarm function: When the vehicle battery power is lower than a certain set value, a low-voltage alarm will occur, indicating that the owner’s battery is low. The usage scenario of the low-voltage alarm is the working state of the device and is detected each time a health message is sent.

Driving behavior analysis: The product has built-in acceleration sensor, which can detect the rapid acceleration, rapid deceleration, and sharp turn of the vehicle. When the vehicle has a bad driving behavior such as sudden increase, sudden decrease, sharp turn, etc., the device will generate a posture message. The actual driving behavior, time, and location information generated are reported to the server for analysis of the driving behavior of the owner.

Collision alarm and filtering function:

When the vehicle generates a collision behavior during driving, the built-in acceleration sensor generates a collision value, and the device generates a collision message, and packages the collision value with the position information and time of the collision to upload to the server. The server will push rescue information to the service station for collision alarms. The product adds collision filtering logic. When it is judged by logic that a real collision occurs, the rescue information will be pushed to the service station, and the misjudgment generated by the filtering will be generated.

External serial port expansion

Function description: The external serial port is expanded, and one channel is reserved, which is convenient for connection with other external devices and expands the product form.
