Road obstacle detector

Abstract

The invention provides a road obstacle detector. The road obstacle detector comprises an ultrasonic wave range finding sensor, a control unit, a computer system, an alarm device and a power supply device, wherein the ultrasonic wave range finding sensor includes an ultrasonic wave emitter and an ultrasonic wave receiving device; the ultrasonic wave emitter is used for emitting an ultrasonic wave signal to a front portion; the ultrasonic wave receiving device is used for receiving a reflected ultrasonic wave signal; the control unit calculates a difference value of time for emitting the ultrasonic wave signal and time for receiving the reflected ultrasonic wave signal, compares the difference value and a preset time difference value and determines whether there is an obstacle in front of a road, and if there is the obstacle, the control unit further calculates an obstacle height; the computer system receives the obstacle height and compares the obstacle height with a preset height threshold, if the obstacle height is greater than the preset height threshold, a vehicle can not pass through and an alarm control signal is emitted; the alarm device emits an alarm signal according to an alarm control signal; and the power supply device provides power for an internal source of the vehicle and the ultrasonic wave range finding sensor. By using the detector of the invention, an early warning effect can be reached so that unnecessary losses during a vehicle running process are reduced.

Description

technical field [0001] The invention relates to the technical field of road detection, in particular to a road obstacle detector. Background technique [0002] With the rapid development of my country's economy, the number of vehicles across the country is increasing day by day, but the roads in our country have not yet been fully leveled. In most 2.3-tier cities and villages, there are still roads that are uneven, with convex and subsidence. As a result, the vehicle is prone to sinking or causing damage to the vehicle chassis, bumper, etc. when the vehicle passes by, causing losses to the vehicle, resulting in unnecessary waste of time and money. In addition, the equipment currently loaded on the vehicle cannot measure it, only by visual inspection, which is too limited and inaccurate, and it is even more difficult to measure when the visibility is relatively low or the speed of the vehicle is relatively fast. Contents of the invention [0003] The aim of the present inve...

[0002] With the rapid development of my country's economy, the number of vehicles across the country is increasing day by day, but the roads in our country have not yet been fully leveled. In most 2.3-tier cities and villages, there are still roads that are uneven, with convex and subsidence. As a result, the vehicle is likely to sink into the vehicle or cause damage to the vehicle chassis, bumper, etc. when the vehicle passes by, causing losses to the vehicle, resulting in unnecessary waste of time and money

In addition, the equipment currently loaded on the vehicle cannot measure it, only by visual inspection, which is too limited and inaccurate, and it is even more difficult to measure when the visibility is relatively low or the speed of the vehicle is relatively fast
