Abstract
The invention discloses an ultrasonic monitoring system of a vehicle speeding on a road and belongs to the technical field of automatic monitoring and control. The ultrasonic monitoring system is characterized by comprising a DSP (digital signal processor) controller (1), an ultrasonic transmitting module (2), an ultrasonic receiving module (3), a camera module (4), an AD (analog/digital) conversion module (5), a DA (digital/analog) conversion module(6), an isolation module (7), a storage module (8) and a wireless transmitting module (9). Compared with the prior art, the ultrasonic monitoring system is simple in structure, convenient to control, high in reliability, convenient to maintain and the like.
Description
Technical field
The invention belongs to automatic monitoring technical field, in particular, belong to a kind of on-highway motor vehicle hypervelocity monitoring ultrasonic system.
Background technology
In prior art, the speed of a motor vehicle of the vehicle on highway is monitored to the mode usually adopting radar velocity measurement, but due to the effect of radar velocity measurement in the intensive situation of vehicle be not ideal, even there will be mistake, how effectively to overcome defect of the prior art and improve a great problem that the integral monitoring effect of highway is restriction the art always.
Ultrasound wave tests the speed and is divided into time difference method and frequency-difference method, and time difference method is used for low speed and measures, and frequency difference rule is used for measuring at a high speed.Time difference method tests the speed and mainly utilizes, and ultrasound wave transmitting and receiving probe is in a certain time interval, double to object under test transmitting and receiving ultrasound wave.According to ultrasonic ranging principle, can, according to during twice emitting and determinand distance, calculate in the twice emitting time interval, the displacement that object under test occurs, and then obtain its speed.The theoretical foundation that frequency-difference method tests the speed then derives from Doppler effect principle, after ultrasound wave transmitting probe launches ultrasound wave, received by ultrasound wave receiving transducer again after the reflections off objects of certain speed motion, hyperacoustic frequency there occurs certain change, according to the relation between this frequency difference, ultrasonic propagation velocity, speed of moving body, speed of moving body can be calculated.Existing ultrasound speed system, is the single application to above two kinds of methods mostly, and when tested speed variation is larger, takes any one in these two kinds of single speed-measuring methods, be all difficult to meet measuring accuracy requirement.Therefore, designing with single-chip microcomputer is core, and integrated poor method tests the speed and frequency-difference method tests the speed in same set of system, becomes the key of the ultrasound speed system being applicable to highway.
Summary of the invention
The present invention, in order to effectively solve above technical matters, gives a kind of on-highway motor vehicle hypervelocity monitoring ultrasonic system.
A kind of on-highway motor vehicle hypervelocity monitoring ultrasonic system of the present invention, is characterized in that: comprise dsp controller, ultrasound wave transmitter module, ultrasound wave receiver module, photographing module, AD conversion module, D/A conversion module, isolation module, memory module, wireless transmitter module; Wherein:
