Abstract
The automatic infrared tracking and detecting equipment consists of rotatable carriage, passive infrared receiver and support to fix the passive infrared receiver. Each of the passive infrared receiving tubes is connected to one independent signal amplifier circuit and one comparator circuit with programmable microprocessor successively. In target object moves, signals are returned from several monitoring points, compared in the comparator circuits and distinguished in the microprocessors to judge the motion direction of the object; drive signal is sent to the driver circuit and the carriage driving mechanism drives the passive infrared receiving tube to rotate towards the motion direction of the object to follow the motion of target object.
Description
Affiliated technical field:
The present invention relates to a kind of sensor, relate in particular to a kind of sensor of object position detection, particularly a kind of position transducer that utilizes ultrared automatic accompany movement object.
Technical background:
In the prior art, infrared position transducer is made of infrared receiving tube, when object appears within the range of receiving of infrared receiving tube, can make infrared receiving tube obtain a signal, processing through amplifying circuit and comparator circuit produces an output signal that target object occurs.But, can't judge the motion conditions of target object.The range of receiving of infrared receiving tube is limited, when target object exceeds range of receiving, then loses the signal of target object.
Summary of the invention:
Technical matters to be solved by this invention is: in the prior art, infrared position transducer is made of infrared receiving tube, when object appears within the range of receiving of infrared receiving tube, can make infrared receiving tube obtain a signal, processing through amplifying circuit and comparator circuit produces an output signal that target object occurs.But, can't judge the motion conditions of target object.The range of receiving of infrared receiving tube is limited, when target object exceeds range of receiving, then loses the signal of target object.The present invention provides a kind of infrared sniffer of following automatically for the technical scheme that the problems referred to above adopted that solves in the prior art, the described this infrared sniffer of following automatically is by rotatable bracing frame, propping up of passive type infrared remote receiver and fixing described passive type infrared remote receiver is configured to, wherein, described support is arranged on the described rotatable bracing frame, described passive type infrared remote receiver comprises 5 passive type infrared receiving tubes at least, described passive type infrared receiving tube is evenly distributed, described any one passive type infrared receiving tube all separately with one independently signal amplification circuit be connected, described signal amplification circuit is connected to a driving circuit, described driving circuit is connected at least one drive motor, and described drive motor is arranged in the bracing frame driving mechanism.Further, at the front end of described passive type infrared receiving tube lens can also be set, described lens are Fresnel Lenses, and are further again, and described lens are made of plural convex lens.Further, around described passive type infrared receiving tube, can also be provided with the active infra-red power valve.Concrete, described signal amplification circuit is connected to a comparator circuit, be provided with a programmable microprocessor in the described comparator circuit, described drive motor adopts stepper motor, and described rotatable bracing frame can adopt the electronic universal turning bench in the prior art.
The course of work of the present invention is: but the active infra-red power valve constantly sends infrared ray to the range of receiving of passive type infrared receiving tube, when object appears within the range of receiving of infrared receiving tube, infrared ray is reflected back toward infrared receiving tube, the lens that are arranged on described passive type infrared receiving tube front end can make the interior object signal of dotted region of passive type infrared receiving tube sensing be returned, when target object continues motion, the monitoring point of a plurality of settings is return signal respectively, through comparator circuit relatively, carry out identification by described programmable microprocessor according to the return signal of the infrared receiving tube of diverse location again, can judge the direction of motion of target object, send drive signal to driving circuit then, bracing frame drive mechanism passive type infrared receiving tube rotates to the direction of motion of target object, thereby follows the motion of target object.
