Abstract
The utility model discloses an umbrella anti-lost reminding device which comprises a power switch, two power supplies, an infrared transmitting device and a receiving and processing device, wherein the receiving and processing device consists of a buzzer, a single chip, an LED (light emitting diode) circuit and an infrared receiving device; the power supplies are connected in series with the power switch; the single chip is connected with a speaker, an LED and an infrared receiving device respectively; when a user forgets the umbrella and walks for a distance and the infrared receiving device exceeds a receiving range, the LED circuit twinkles to send visual caution that the umbrella is forgot; if the user still does not discover the situation, alarm sound is generated after a time delay, and audio caution is provided to remind the user of the forgotten umbrella; and the circuit has the advantages of simple structure and strong practicability.
Description
Technical field
The utility model relates to a kind of alarm set, the anti-lost alarm set of espespecially a kind of umbrella.
Background technology
Umbrella is indispensable in a people's daily life instrument, no matter Sometimes When It Rains, when still ultraviolet ray was strong, people can use umbrella; Because the transformation of weather, that perhaps walks is hasty, and people often forget that a umbrella that leads out takes back, and cause umbrella to lose, and bring unnecessary loss to the user.
The utility model content
The purpose of this utility model provides the anti-lost alarm set of a kind of umbrella, within infrared receiver exceeds range of receiving outside after, chimes of doom is sent in LED flicker after the time-delay.
For achieving the above object, the anti-lost alarm set of a kind of umbrella of the utility model, comprise power switch, two power supplys, infrared launcher and receiving and processing devices, described receiving and processing device is comprised of loudspeaker, single-chip microcomputer, led circuit and infrared receiver, power supply is connected with power switch, and single-chip microcomputer links to each other with loudspeaker, LED and infrared receiver respectively.
As preferably, power supply is comprised of battery, gives respectively the power supply of infrared launcher and receiving and processing device.
As preferably, in 5 meters of the infrared lights of described infrared launcher emission.
As preferably, described infrared receiver does not receive the signal that infrared launcher sends, infrared receiver is to signal of single-chip microcomputer, the Single-chip Controlling led circuit is luminous, the single-chip microcomputer timer internal is regularly more than 5 seconds, still do not receive the signal that infrared launcher sends, Single-chip Controlling loudspeaker sounding.The beneficial effects of the utility model are: when the user falls umbrella, and walked a segment distance, after outside infrared receiver exceeds in the range of receiving, the led circuit flicker, visual alarm user's umbrella has fallen, if the user does not also find, send chimes of doom after the time-delay, sense of hearing caution people umbrella has fallen; Circuit structure is simple, and is practical.
Description of drawings
Fig. 1 is structured flowchart of the present utility model;
Fig. 2 is software systems side figure of the present utility model.
Embodiment
See also Fig. 1 and Fig. 2, the anti-lost alarm set of a kind of umbrella, comprise power switch 111, two power supplys 121, infrared launcher 141 and receiving and processing device 131, described receiving and processing device 131 is by loudspeaker 181, single-chip microcomputer 151, led circuit 171 and infrared receiver 161 form, power supply 121 is connected with power switch 111, single-chip microcomputer 151 respectively with loudspeaker 181, led circuit 171 links to each other with infrared receiver 161, open the power switch 111 of infrared launcher 141 and the power switch 111 of receiving and processing device 131, infrared launcher 141 is launched infrared light, infrared receiver 161 receives infrared light, and signal passed to single-chip microcomputer 151, circuit is failure to actuate, until can not receive the infrared light arrival constantly of infrared launcher 141 emissions.
Wherein, power supply 121 is comprised of battery, gives respectively infrared launcher 141 and receiving and processing device 131 power supplies; The infrared light of described infrared launcher 141 emissions is in 10 meters; When described infrared receiver 161 does not receive the signal that infrared launcher sends, 171 flickers of single-chip microcomputer 151 control led circuits, single-chip microcomputer 151 timer internals regularly more than 5 seconds, still do not receive the signal that infrared launcher 141 sends, single-chip microcomputer 151 control loudspeakers 181 sounding.
The utility model circuit structure is simple, and is practical; When the user falls umbrella, and walked a segment distance, outside infrared receiver exceeds in the range of receiving after, the led circuit flicker, visual alarm user's umbrella has fallen, if the user does not also find, send chimes of doom after the time-delay, sense of hearing caution people umbrella has fallen.
The above only be embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
