Abstract

The invented device combines with the pickup for monitoring the target distance. The device includes the monitor, the video frequency digital signal controller, the audio frequency signal controller,the ultrasonic signal drive and receiver as well as ultrasonic sensor. The video frequency digital signal controller and the audio frequency signal controller are composed of the monolithic processor, the master clock oscillator, the impedance matching circuit for inputting digital signal, the character matrix clock rate oscillator, the voice output impedance matching circuit, the output impedance matching circuit and input impedance matching circuit. The video frequency digital signal controller and the audio frequency signal controller receive the field synchronization signal and the row synchronization signal output by the monitor, read out the ultrasonic signal drive, which links to the ultrasonic sensor.

Description

technical field

[0001] The invention relates to a monitoring device and a monitoring method, in particular to a device and a method capable of monitoring target distance in combination with imaging. Background technique

[0002] Existing distance monitoring devices, such as ultrasonic ranging radar, can only measure the distance of the target, and cannot meet the requirements when it is necessary to know the shape and distance of the target at the same time. For example, when a car is reversing, due to the limitation of the field of view, accidents such as collisions may occur, especially for buses and vans, if no one directs them, they cannot reverse. Existing vehicles currently on the market are equipped with a camera at the rear, which can display the situation behind the car through the screen of the monitoring device. There is also a reversing radar installed with ultrasonic ranging, and the obstacle behind the car can be displayed through the ...
