Feature
1. Limit speed intelligently according to speed limit values of the road
2. The device is widely applicable, can be used in mostly 12 v ~ 24 v vehicles
3. It is easy to install the device and it is anti-shock
4. Strong stability: Design of short circuit protection, built-in circuit of preventing over current.
5. Design of combining electronic technology with machinery, one installing for forever.
6. Study intelligently the features of vehicle. It will reduce setting of same kind of vehicle.
7. Alarm of cutting of power wire.
8. Limit speed safely without affecting vehicle's horsepower
Function
1. Feet management
(1)Record the data of running status:
Speed and status of vehicle's running status.
(2) Record the historical route of vehicle.
2. Over speeding alarm and limit vehicle speed
When vehicle speed become over the speed limit value, the device sound the alarm and send the alarming data to the control center. If the driver didn't slow down the car, the device will limit vehicle speed.
3. Update the data
The device can send the data to control center via GPRS/CDMA module and communications bases.
4. Function of self-inspection
When the device connects the power, it inspects itself and sound "di" shows that it works well.
5. Function of power-off protection
The device has built-in storage and will update the important data to the control center.
6. Function of anti-interference
The device takes measures to be resistant to interference, so it can ensure the reliability of recorded data.
Function of self-inspection
When the device connects the power, it inspects itself and sound "di" shows that it works well.
Function of Speed Limit
When vehicle speed reach the speed limit value, the device sound the alarm ("di", "di", "di" ring slowly)
When vehicle speed is more 10% than the speed limit value, the device will limit vehicle speed to make it less than the speed limit value ("di", "di", "di" ring fast)
When vehicle change lanes, the device will stop limiting vehicle speed and sound the alarm ("di", "di", "di" ring fast)
When vehicle speed becomes less than the speed limit value, the device stop limiting the speed and sounding the alarm
