In the utility model, the CIT ultrasonic wave automatic door opening sniffer proposed, comprise the first ultrasonic detector, the second ultrasonic detector, discriminator circuit, controller, door opener, first ultrasonic detector and the second ultrasonic detector lay respectively at vent cabinet cabinet door both sides, first ultrasonic detector is connected with discriminator circuit respectively with the second ultrasonic detector, discriminator circuit is connected with controller, and controller is connected with door opener.By the CIT ultrasonic wave automatic door opening sniffer of above-mentioned optimal design, pulse is sent to discriminator circuit according to detection signal by the first ultrasonic detector and the second ultrasonic detector, the signal received differentiated by discriminator circuit, thus when operating personnel enter in detection range, make controller control door opener and automatically open vent cabinet cabinet door, improve automaticity, convenient operating personnel's work.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of CIT ultrasonic wave automatic door opening sniffer that the utility model proposes.
Detailed description of the invention
As shown in Figure 1, Fig. 1 is the structural representation of a kind of CIT ultrasonic wave automatic door opening sniffer that the utility model proposes.
With reference to Fig. 1, a kind of CIT ultrasonic wave automatic door opening sniffer that the utility model proposes, comprising: the first ultrasonic detector 1, second ultrasonic detector 2, discriminator circuit, controller, door opener;
First ultrasonic detector 1 and the second ultrasonic detector 2 all adopt HC-SR04 type ultrasonic distance measuring module, the two lays respectively at vent cabinet cabinet door both sides and is positioned in the same level on distance 1 meter, ground, the ultrasonic wave direction of transfer frontage and airiness cabinet cabinet outer side of door of the first ultrasonic detector 1, and become 30 degree of angles with vent cabinet cabinet door place plane, the ultrasonic wave direction of transfer frontage and airiness cabinet cabinet outer side of door of the second ultrasonic detector 2, and become 30 degree of angles with place, vent cabinet front plane;
First ultrasonic detector 1 is connected with discriminator circuit respectively with the second ultrasonic detector 2, and discriminator circuit is connected with controller, and controller is connected with door opener.
Adopt in the course of work of the CIT ultrasonic wave automatic door opening sniffer of the present embodiment, first ultrasonic detector 1 and the second ultrasonic detector 2 send high level pulse according to detection signal, pulse width is directly proportional to the distance of ultrasonic detector apart from object to be detected, discriminator circuit by the pulse from ultrasonic detector whether in predetermined threshold range, if the pulse received is in predetermined threshold range, then export high level pulse to controller, thus vent cabinet cabinet door opened by control door opener.
In the present embodiment, the CIT ultrasonic wave automatic door opening sniffer proposed, comprise the first ultrasonic detector, the second ultrasonic detector, discriminator circuit, controller, door opener, first ultrasonic detector and the second ultrasonic detector lay respectively at vent cabinet cabinet door both sides, first ultrasonic detector is connected with discriminator circuit respectively with the second ultrasonic detector, discriminator circuit is connected with controller, and controller is connected with door opener.By the CIT ultrasonic wave automatic door opening sniffer of above-mentioned optimal design, pulse is sent to discriminator circuit according to detection signal by the first ultrasonic detector and the second ultrasonic detector, the signal received differentiated by discriminator circuit, thus when operating personnel enter in detection range, make controller control door opener and automatically open vent cabinet cabinet door, improve automaticity, convenient operating personnel's work.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
