Gross 1.0kg, 0.9kg HT3000 net technical parameters of the motor vehicle radar speedometer vehicle radar gun as a radar device, change the frequency value when it works irradiation frequency signal emitted by the radar moving target reflecting its role within the scope of (Doppler effect). This Doppler shift is proportional to the speed of the moving object. Key features of HT3000 vehicle radar gun for narrow radiation pattern, to ensure a narrow detection area. After being monitored target car into a narrow detection area, the radar gun sends a trigger signal, connected via RS-232 and RS485 communication protocol with an external control device (computer). Speedometer structure is waterproof and hit the chassis, including the high-frequency transmitter, a microprocessor and a data processing switching circuit board, all mounted in a sealed enclosure. Speedometer is used together with peripheral devices simultaneously, the communication channel with the RS-232 and RS-485. 1. The radar emission angle of the speedometer microwave radiation instrument, using matrix flat panel antenna, antenna radiation patterns stenosis. Space exploration area is determined by the radiation pattern angle, angle parameters (radiation intensity is greater than the spatial region -3dB):? Horizontal interface: 5.5 ° vertical Interface:? 6.5 ° 2. Accuracy speedometer speed accuracy of 1 km / h . 3. connections and power supply connected to an external device via multi-thread connections, including: -RS-232 connector, the transmission rate of 9600 bit / s (serial ports, 3-wire) for tachometer control, and the external device Output test vehicle information (see Table 1); -RS-485 connector, the transmission rate of 9600 bit / s (serial ports, 3-wire) for tachometer control, and output to an external device under test vehicle information (see Table 1 ); - speedometer power supply (2-wire); 4. Environmental conditions: - ambient air temperature at minus 40 ℃ ~ zero within a range of 60 ℃; - at 25 ℃ 98% relative humidity; - shock 200Hz, less than 2g - 10ms within impact, less than 5g 5. radar frequency - speedometer emission frequency of 24.105 ~ 24.195 GHz - gun transmit power shall not exceed 25 mW 6. Power requirements - Supply voltage (direct electrical), 12V - Current consumption speedometer should not more than 250 mA 7. speedometer structure dimensions, mm, not more than: height 160 width 160 thickness 90 speedometer weight: less than RS232 serial communication setting should be the following two kilograms 8 serial communication protocol and speedometer connections: - Porter the rate of 9600 bits / sec. - Stop Bit 1 - 8 data bits - Parity non-serial protocol corresponds to the following table: 1st byte speed value one hundred 0x30--0x39 second byte speed value ten 0x30--0x39 3 0x30--0x39 speed values ??bit byte 4th byte decimal point after the first 5 bytes decimal point 0x30--0x39 sixth byte carriage return 0x0d 0x0a byte 7 9600 baud no parity one stop Bit RS485 output format: triggered when a vehicle enters the detection area and gives speed value, a total of 4 bytes, FC trigger signal FA-speed packet prefix S velocity values, hex, units KM / H 00 internal byte target Radar information format is the active mode, the radar does not need to send a special command, when a vehicle passes through the detection zone (not case come to and whereabouts), and signal strength to meet the limit set, the radar will automatically give a trigger signal . Which is measured to the (reverse) vehicles. When the vehicle enters the detection area, the radar will give immediate trigger signal and speed values ??in the following format RS485 signal can be used to access the computer and camcorders.
