Background technology
Generally than very fast, human pilot is often ignored the speed of a motor vehicle to the vehicle on expressway travel speed in driving for a long time, under situation off one's guard, is very easy to occurrence of traffic accident; And in the generation of obviously minimizing accident of certain dangerous highway section restricted speed.
Have only guideboard to be used for reminding the human pilot maximum speed limit on tradition highway and the Dangerous Area, the prompting means of static state such as maintain safe distance; People's vision system tends to the thing of static state is ignored, and therefore static prompting mode can't cause the vigilance that human pilot is enough.
Summary of the invention
Not enough to above-mentioned prior art, the purpose of the utility model is to provide a kind of vehicle speed alarm device based on the radar velocity measurement technology, and it adopts the dynamical fashion alerting drivers to note the speed of a motor vehicle, guarantees safety traffic, the generation of minimizing accident.
The utility model is the technical scheme that its purpose of realization is taked: a kind of vehicle speed alarm device based on the radar velocity measurement technology; Comprise velocity radar; Said velocity radar is connected with main control circuit unit alternately; The output terminal of said main control circuit unit is connected with the input end of LED digital display screen, and power supply is to each device power supply.
Said velocity radar comprises radar detedtor and DSP signal processing circuit, and said DSP signal processing circuit is made up of A/D sample circuit, dsp processor and the communication serial port of mutual connection successively; Said main control circuit unit comprises ARM managing chip and charge in batteries managing chip UC3906; Said communication serial port is connected with the input end of ARM managing chip; The output terminal of said ARM managing chip is connected with the communication interface of LED digital display screen.
Said power supply adopts civil power or solar cell.
The beneficial effect of the utility model: utilize the real-time measurement of vehicle speed of High Accuracy Radar; And show with red high bright LED digital display screen, give the prompting of dynamic vehicle speed to run at high speed vehicle and road hazard location, through LED screen flicker demonstration; Remind and warning function to play; Make the driver note the speed of a motor vehicle, safety traffic, the generation of minimizing accident.Give the prompting of dynamic vehicle speed to run at high speed vehicle and road hazard location, with raising human pilot vigilance, thus the generation of minimizing traffic hazard.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation block diagram of the utility model;
Fig. 2 is the utility model DSP signal processing circuit structure schematic block diagram;
Fig. 3 is the main control circuit unit structural representation of the utility model.
Embodiment
Shown in Fig. 1-3, the utility model is made up of power supply 1, velocity radar 2, LED digital display screen 3, main control circuit unit 4.Velocity radar 2 is connected with main control circuit unit 4 alternately, and the output terminal of main control circuit unit 4 is connected with the input end of LED digital display screen 3, and power supply 1 is to each device power supply of device.Power supply 1 can adopt solar cell 11 or adopt civil power 12 to be whole device power supply.Velocity radar 2 is made up of radar detedtor 21 and DSP signal processing circuit 22.DSP signal processing circuit 22 is made up of A/D sample circuit, dsp processor and the communication serial port of mutual connection successively, and communication serial port adopts RS232.Main control circuit unit 4 comprises that ARM managing chip 43 and charge in batteries managing chip 42 adopt the UC3906 chip; The communication serial port of DSP signal processing circuit 22 is connected with the input end of ARM managing chip; The output terminal of ARM managing chip 43 is connected with the communication interface of LED digital display screen 3.Main control circuit unit 4 main solar cell 11 intelligent charges of being responsible for are managed; With prevent to overcharge, overdischarge is to the infringement of battery; Receive the data after DSP signal processing circuit 22 is handled simultaneously and demonstrate car speed through the LED number; When car speed surpassed preset hypervelocity speed, the speed of displaying data were reminded human pilot through ceaselessly glimmering.
LED digital display screen 3 is that the digital module of red high bright LED constitutes, and digital module can be dismantled and splice.Fig. 3 is the main control circuit unit structural representation.It is that radar detedtor and LED digital display screen provide electric energy that civil power converts direct current 2V to through bridge circuit; Charge in batteries managing chip UC3906; Its charging principle meets the charging curve of accumulator; Can prevent to overcharge the damage that causes battery according to several charging stages such as the actual electric weight realization trickle maintenance charging of accumulator, big electric current rapid charge, pressure limiting floating charges, make charge efficiency maximum simultaneously.ARM managing chip 43 is the high performance programmable chip; LDO voltage stabilizer 45 provides 3.3V WV for it; But overdischarge threshold values through programming software set accumulator; The ARM managing chip sends control signal to UC3906 when the voltage of accumulator drops to threshold values, through controlling voltage comparator 44 with the cutoff device load circuit; Pass through the reception and the transmission of serial ports RS232 Communication Realization data between main control circuit unit 4 and the DSP signal processing circuit 22.The data that main control circuit unit 4 receives convert digital value to through the calculating of ARM managing chip internal arithmetic device and are shown by the LED digital display screen.
This device generally is installed on highway and hazardous location road one side, and radar detedtor 21 installation directions and measured road are installed so that the signal intensity that radar receives is maximum according to certain included angle.The DSP signal processing circuit converted rate signal to digital signal that main control circuit unit 4 is discerned to the signal employing and through the fft algorithm design after radar detedtor recorded vehicle velocity signal.The utility model adopts two cover power supply modes, is the speed measuring device power supply there being the civil power zone can directly adopt civil power; Under the environment of no civil power, can use solar cell to receive solar energy and electric energy is provided, and unnecessary electrical power storage is arrived accumulator as device.
When only having a car to sail; Radar detedtor 21 can collect the rate signal of vehicle outside apart from 100 meters; 22 pairs of vehicle velocity signals of DSP signal processing circuit carry out algorithm process obtain main control circuit unit 4 can recognition data stream, the data stream that obtains is shown through LED digital display screen 3; When having several cars to sail simultaneously simultaneously, the radar velocity measurement device will show a most preceding vehicle speed always.When no vehicle through out-of-date, main control circuit unit 4 is closed the LED display system to reduce device power consumption.
