Abstract
The utility model provides an ultrasonic automatic detection device for traffic pavement gathered water, and belongs to the field of electronics. The detection device comprises an ultrasonic transmitting module, an ultrasonic receiving module and an ultrasonic signal processing module, wherein the ultrasonic transmitting module and the ultrasonic receiving module are arranged at the front end of an automobile; the ultrasonic signal processing module is arranged in the automobile; a data output end of the ultrasonic receiving module is connected with a data input end of the ultrasonic signal processing module; an output end of the ultrasonic signal processing module is connected with a data input end of an underwater pavement defect alarm module; and an embedded processor in the ultrasonic signal processing module calculates the unevenness of an underwater pavement according to the reflection information of inputted ultrasonic waves in different mediums (water or pavements or cavity interfaces), and once a preset numerical value exceeds, an alarm device is started so as to provide certain guarantee for traffic safety in gathered water.
Description
Technical field
The utility model belongs to person in electronics, relate to use the ultrasonic listening technology detect in real time under the ponding road surface planeness and to overproof technology of reporting to the police.
Background technology
Exist some to utilize the technology of other sensor measurement planeness on technology in the past or market, but general product or technology is being difficult to satisfy the speed of running car, the requirement of environment aspect conversion speed, extensive area measurement, cost.
Summary of the invention
The purpose of this utility model is to provide a kind of based on ultrasonic listening technology high-speed measuring system, this system projects ultrasonic wave on the ponding road surface of automobile direct of travel, receive its reflected signal on water and road surface or damaged road surface with ultrasonic receiver again, calculate through corresponding, just can draw the defective under water on the vehicle front road surface of advancing, can obtain the defect information on continuous road surface through computing, then compare with the standard of setting and just can accurately draw the overproof size in road surface under ponding.
Hardware of the present utility model is by the ultrasonic wave transmitter module that is arranged on automotive front end, ultrasonic wave receiver module and be arranged on the ultrasonic signal processing module of automotive interior, defective alarm module in road surface forms under water, can realize fast the overproof automatic measurement in ponding road surface.
The technical solution of the utility model is: comprise the ultrasonic wave transmitter module, the ultrasonic wave receiver module that are placed in automotive front end; The ultrasonic signal processing module is arranged on automotive interior.The data output end of ultrasonic wave receiver module connects the data input pin of ultrasonic signal processing module; The output of ultrasonic signal processing module connects the data input pin of road surface defective alarm module under water.Flush bonding processor in the ultrasonic signal processing module is according to the reflective information of the ultrasonic wave of inputting at different medium (water and road surface or hollow interface), calculate the irregularity degree on road surface under water, in case surpass predetermined numerical value, to start warning device, for the traffic safety in ponding provides certain guarantee.
The advantage that the utlity model has is:
1. measuring speed is fast.
2. measure coverage broad.
Description of drawings
Fig. 1 is block diagram of the present utility model;
Fig. 2 is configuration schematic diagram of the present utility model;
The specific embodiment
As shown in Figure 1, a kind of driving surface gathered water of the utility model ultrasonic wave automatic detection device, after the ponding information of road surface process ultrasonic wave receiver module input message that gathers, pass through successively ultrasonic signal processing module, road surface defective alarm module under water, the most backward driver provides reliable information of road surface.
Described ultrasonic wave transmitter module comprises 2 supersonic generators and control circuit, changes electric energy into ultrasonic wave again with its directional transmissions.
Described ultrasonic wave receiver module comprises 2 ultrasonic transducers and treatment circuit, with ultrasonic signal reception, acoustic-electric conversion, amplification, the denoising that reflects in ponding.
Described ultrasonic signal processing module refers to: will launch with the ultrasonic signal that reflects and compare computing, and draw poor graph curve reflection interval, thereby derive the planeness information on ponding road surface.
The overproof alarm module in described road surface refers to: road surface flatness information and the flatness bound that sets in advance are compared, provide overproof alarm signal.
As shown in Figure 2, being arranged on supersonic generator 2 on automotive front end 1 launches ultrasonic wave 3 and projects on measured vehicle front road surface 4; Ultrasonic receiver 5 is with ultrasonic wave 6 incomes that reflect.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
