To be applied to personnel's traffic monitoring of vehicle and the principle of analytic system describes in detail to the utility model below.

Switching signal pick-up unit 70 is continual to carry out work, and the radar beam of radar sensor emission in it covers whole car doors, the switch motion of continual detection car door, and be sent to MCU30 when its switching signal that is converted to numeral.

After MCU30 receives the signal of switching signal pick-up unit 70 transmissions, judge that this signal is enabling signal or closes gate signal, when being judged as enabling signal, send work orders to described power supply 60, control controllable electric power in the described power supply 60 and partially open power supply is provided.

After the controllable electric power work of described power supply 60, it provides working power for described radar monitoring device, activate and trigger described radar monitoring device and start working, described radar monitoring device transmitting radar waves bundle, its radar beam covers the zone of car door place passenger getting on/off, and is approximately perpendicular to surface level; When the passenger gets on the bus or gets off action, the passenger is relative, and radar beam is done radial motion, described radar monitoring device can produce in the same way, the two paths of signals of quadrature (I, Q two paths of signals), I, identical, phase phasic difference 90 degree of Q two paths of signals amplitude, I, Q two paths of signals reflect directional information and velocity information jointly.Wherein, directional information promptly is that the described relatively radar monitoring device of passenger is done close or away from motion, velocity information promptly is the instantaneous velocity of passenger getting on/off door.Described radar monitoring device is sent to described data analysis treating apparatus 20 with I, Q two paths of signals.

The principle that 20 couples of described I of described data analysis treating apparatus, Q two paths of signals carry out analyzing and processing is as follows:

Because I, Q two paths of signals are surveyed by described radar monitoring device (being the plane doppler radar sensor) and obtained, this two paths of signals all has certain Doppler frequency f _D, this frequency range and passenger's the speed of getting on or off the bus has certain relation, shown in following formula:

$f_D=2f_0\·\frac{v}{c_0}\·\cos \mathrm{\α}---\left(1\right)$

Wherein, f _DBe Doppler frequency or difference frequency, f ₀Be the transmission frequency of radar monitoring module, v is the instantaneous velocity of passenger getting on/off, C ₀Be the light velocity, α is the actual direction and described plane doppler radar sensor---the angle between the target link of motion.

Because passenger's the relative radar beam of action of getting on or off the bus is roughly radial motion, then the value of α gets 0, and promptly formula (1) can be rewritten as:

$f_D=2f_0\·\frac{v}{c_0}---\left(2\right)$

Because passenger's the speed v of getting on or off the bus must be within the specific limits, i.e. f _DValue must be also in a certain scope, then can be according to the f of reality _DScope determine the frequency values of described bandpass filter 201 to make f _DSignal be able to by, and all the other undesired signals and noise signal are by filtering., after described amplifier 202 amplifies, carry out sampling processing through AD converter 203 again, and be converted to digital signal corresponding from the signal of described bandpass filter 301 outputs; Two ways of digital signals after described AD203 conversion is sent to the phase place discriminating that phase-shift discriminator 204 carries out two paths of signals on the one hand, and then sends into DSP205 and carry out digital signal processing; On the other hand, this two ways of digital signals directly is sent to described DSP305 and is carried out digital signal processing, and wherein, described DSP205 carries out the processing of frequency and amplitude to the two ways of digital signals that directly receives from AD203, obtains velocity information.

Wherein, 204 pairs of two ways of digital signals of phase-shift discriminator carry out obtaining a phase difference value ΔΦ after phase place differentiates, the positive negative variance of ΔΦ is promptly represented I, which Lu Zaiqian of Q signal, when I road signal preceding, then be the motion of getting on the bus, otherwise then be the motion of getting off.Subsequently, the phase differential ΔΦ of described two paths of signals is sent to analysis and the processing of carrying out digital signal in the DSP device 205, obtains directional information.To sum up, DSP device 205 directional information and the velocity information that will finally obtain is sent to MCU50.

MCU30 judges according to receiving velocity information whether the passenger has carried out the motion of getting on or off the bus; MCU30 is according to directional information, judges to obtain passenger's carried out getting on the bus action or get off action.Particularly, described MCU30 at first comprehensively judges whether to receive simultaneously velocity information and directional information, if judged result is for being, then continue according to directional information, the judgement passenger has carried out getting on the bus and has moved or the action of getting off, carried out the action of getting on the bus if judge the passenger, then assigned and add steering order to counter 206; If judge that the passenger has carried out the action of getting off, then assign the down control instruction to counter 206.

Described counter 206 is counted under the control of MCU30 automatically, promptly, described MCU30 adds steering order when judging to have the people to get on the bus and assign, described counter 206 adds 1 automatically, and when described MCU30 judges have the people to get off and assign the down control instruction, described counter 206 subtracts 1 automatically.After described counter 206 is finished counting work, promptly obtained the real-time passenger flow data of described vehicle, described MCU30 promptly controls and should be stored in the described storer 40 by real-time passenger flow data.Be understandable that because storer 40 meeting zero clearings under predetermined condition, therefore, described counter 206 carries out counting statistics on 0 basis.In addition, described counter 206 can carry out the purpose that work reaches counting for one or more counters, does not give unnecessary details at this.

Afterwards, described MCU30 calls communication interface 50, and the real-time passenger flow data in the storer 40 is uploaded to the passenger transportation management center.

Receive the signal of switching signal pick-up unit 70 transmissions once more as MCU30 after, judge that this signal is enabling signal or closes gate signal, when being judged as the pass gate signal, send the instruction that quits work to described power supply 60, the controllable electric power of controlling described power supply 60 partly turn-offs, then described controllable electric power stops to provide working power for described radar monitoring device and described data analysis treating apparatus 20, and then described radar monitoring device and described data analysis treating apparatus 20 are in dormant state.

Above-mentioned is the principle of work of the vehicle-mounted passenger flow monitor and analysis system of the utility model embodiment, is understandable that, in the passenger traffic process, if the passenger getting on/off action takes place repeatedly, then repeats said process, does not give unnecessary details at this.
