Abstract
The utility model relates to an article finder based on a one-chip microcomputer. The article finder based on the one-chip microcomputer comprises an alarm transmitting end placed at a fixed position and an alarm receiving end bound with an object, wherein the alarm transmitting end comprises a casing and a controller arranged in the casing, the controller is a system comprising a power source, the one-chip microcomputer, a supersonic wave transmitter and a button, the alarm receiving end comprises a casing and a control circuit arranged in the casing, the control circuit is a closed circuit comprising a relay, a supersonic wave receiver, a light emitting diode, a loudspeaker and a cell. By controlling the button of the alarm transmitting end, the alarm circuit emits an alarm signal to realize tracking and searching of the object.
Description
Technical field
The utility model provides a kind of SCM Based article searching device, belongs to the telechiric device field.
Background technology
In daily life, we often can forget where the small articles such as key, charger have been placed on, and sometimes need to turn over all over whole room, have caused very large puzzlement to us.
Summary of the invention
The technical matters that solves: the defective that exists for overcoming above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of SCM Based article searching device, uses the convenient and swift article that find of its energy.
Technical scheme: a kind of SCM Based article searching device, the warning receiving end that comprises the alarm transmission end that is placed on the fixed position, binds together with article.The alarm transmission end comprises housing and is arranged on controller in housing, and described controller is one to comprise the system of power supply, single-chip microcomputer, ultrasonic transmitter and button.The warning receiving end comprises housing and is arranged on control circuit in housing, and described control circuit is one to comprise the closed circuit of relay, ultrasonic receiver, light emitting diode, loudspeaker, battery.In the alarm transmission end, single-chip microcomputer P0.4 mouth and P0.5 mouth connect respectively the both positive and negative polarity of power supply, and the P1.0 mouth of single-chip microcomputer connects button, and the P1.1 mouth connects ultrasonic transmitter.In the warning receiving end, the base stage of triode is connected with ultrasonic receiver, the transmitter ground connection of triode, and the collector of triode is connected with relay, the other end of relay in succession loudspeaker and light emitting diode.
The alarm transmission end is placed on obvious fixed position, as it is first-class to be positioned over refrigerator, the convenient use; Warning receiving end and article bind together, as hang on key ring.
When seeking article, the transmitting terminal button that pushes for emergency, alarm transmission end level is drawn high, ultrasonic sensor sends signal, and after the ultrasonic receiver of warning receiving end received this signal, the relay normally closed switch was opened, lumination of light emitting diode, loudspeaker sounding alarm simultaneously.After finding article, by the button of alarm transmission end, the warning receiving end stops luminous and sounding type again.
Beneficial effect: utilize this SCM Based article searching device can find fast the article that will look for, easy to use, solved and sought the puzzlement of the small article that disappears into thin air in the daily life.

Embodiment
Embodiment 1
As shown in Figure 1, this SCM Based article searching device comprises alarm transmission end and warning receiving end.
As shown in Figure 2, alarm transmission end control chip is the 80C51 single-chip microcomputer, its effect is to control push button signalling, and when finding key, button 3 is pressed, alarm transmitting terminal level is drawn high, the alarm receiving end is started working simultaneously, after key finds, again presses, alarm transmitting terminal level drags down, and the alarm receiving end quits work simultaneously.
As shown in Figure 3, the warning receiving end is controlled light emitting diode and loudspeaker by relay, after receiving high level signal, coil electricity, normally closed contact separates, and normally opened contact is closed, light emitting diode 6 is luminous, while loudspeaker 7 sounding, thus help people to find object; After receiving low level signal, coil blackout, moving iron core is with moving contact to reset under the effect of spring, and the dimmed while loudspeaker 7 of light emitting diode 6 stops sounding.
