Solar radar speed LED vehicle speed feedback instrument traffic signs
First, the overview of solar radar speed
1.Radar over speed display large screen is measured by microwave radar speed measuring instrument on the road speed, the test methods use Doppler principle, use microblogging irradiation driving vehicles, from the return of the microblogging signal extracted the target speed signal, convert values for the corresponding velocity, and compared the system within the speed limit value, If the test speed is greater than the limit value, red will show the value of the test, if less than the speed limit, green will show the speed value.
2.The speed limit value of the system is stored in the removable memory, it will not be lost after the power outage, the speed limit value can be set by five point remote control with random match.
3.Speed display uses 7 3 segment double color digital display to display, equipped with a dedicated high-power drive circuit to drive the display, display uses the static display, display the speed of information clear without flicker.
4. The system can be powered by a DC power supply or solar panels to provide
