Object moving direction sensing device

Abstract

An object moving direction sensing device comprises a control circuit, a mounting base, an infrared emitter and a plurality of infrared receivers, wherein the infrared emitter comprises an infrared illuminator; the infrared receivers comprise photosensitive elements; the infrared illuminator and the photosensitive elements are all arranged on the mounting base; the photosensitive elements are in different positions on the mounting base; each infrared receiver is connected with the corresponding input terminal of the control circuit; infrared light emitted by the infrared illuminator is reflected after meeting an object; after a photosensitive element receives the reflected infrared light, the infrared receiver of the element outputs a signal to the control circuit; the control circuit judges the moving direction of the object according to the signals from the infrared receivers. The sensing device can be used for sensing the object, and judging the moving direction of the object, and can generate corresponding control signals according to concrete application circumstances, and output the control signals to an executing mechanism, so as to realize corresponding operation control.

Description

technical field [0001] The invention relates to the field of sensing technology, in particular to a device for sensing the moving direction of an object. Background technique [0002] The traditional way to control the remote controlled object (that is, the operator can control the controlled object without direct contact with the controlled object) is generally remote control, which uses the remote control to control the controlled object (such as toys, electrical equipment, etc.) , mechanical equipment, etc.) for control, the remote control generally includes an operating device, an encoding device and a sending device, and the controlled object is generally equipped with a receiving device, a decoding device and an executing agency. [0003] For example, remote control toys generally include a remote control and a movable toy body (controlled object), and the operator sends signals through the remote control to control the activities of the toy body. Usually, the remote ...

AI Technical Summary

Problems solved by technology

[0005] To use the above remote control method to control the remote controlled object, it is necessary to be equipped with a remote controller that is separated from the controlled object. ) are easily damaged after frequent operation

For remote-controlled toys, the activity of the main body of the toy is controlled by the remote control, which also has the disadvantage of being more difficult to operate, and this method of controlling the activities of the main body of the toy by the remote control is less interesting, and has become less attractive to consumers. gradually weaken
