Abstract

The invention relates to an energy-saving electricity getting and door closing reminder, in particular to a dormitory electricity getting and door closing reminder which can prevent householders from carelessly wasting electric energy and using the electric energy by stealing. The reminder comprises a reflective optoelectronic coupler, a 555 timer, a relay control circuit, a alternating voltage control circuit, a timing and alarming integrated circuit, a door magnistor and the like. The invention is an electronic device reminder which is suitable for being assembled and used in a dormitory and is composed of the 555 timer, the door magnistor, the optoelectronic coupler and the alarming device. When users come back to the dormitory, the electricity can be used only by inserting a card; and when the users leave the dormitory, the power supply can be cut off, and a reminding alarm can be given out in time if the door is not closed.

Description

Energy-saving electricity-supplying and door-closing prompter

Technical field

The present invention relates to a kind of energy-saving electricity-supplying and door-closing prompter, specifically is a kind of mistake waste electric energy and stolen dormitory power taking, reminiscences of closing the door that uses that allows resident family avoid and not being in the mood for.

Technical background

Electrical equipment such as door status switch, 555 timers, alarm are applied in the electrical equipment in various fields already, and develop a kind of has power taking simultaneously and the electrical part of reminding of closing the door does not also have up till now and these devices are combined.

The dormitory of school or company and enterprise is the resident family district of a collectively owned business, also forget during the no one in the dormitory turn off the light, electrical equipment waste power supply phenomenons such as fan, air-conditioning have caused huge energy loss; Usually do not shut up the door carefully when catching up with hurriedly when going out, and it is a lot of to pass in and out the people in building every day, some lawless person infiltrates and sees some dormitory no ones and door does not shut, and causes property etc. stolen.

Summary of the invention

The present invention's a kind of " energy-saving electricity-supplying and door-closing prompter " is one and is fit to be installed in the electron device reminiscences by combination of devices such as 555 timers, door status switch, photoelectrical coupler, alarm apparatus that dormitory uses.The objective of the invention is to be to allow resident family avoid mistake waste electric energy and stolen dormitory power taking, the reminiscences of not being in the mood for of closing the door that uses; Comprise six parts compositions such as reflecting photoelectric coupler, 555 timers, control relay circuit, alternating voltage control circuit, timing and alarming integrated circuit, door status switch; When people get back to dormitory, as long as plug-in card just can normal electricity consumption, but and when leave dormitory powered-down, and when not shutting, can in time send reminder alerting.

Implementation procedure of the present invention

Install tongue tube and small magnet at door respectively and lock, tongue tube separates with small magnet when opening the door, start timer, insert magnetic card, start the power supply electricity consumption, simultaneously timer is resetted, do not close and close the timer timer to the doorstep and will start warning to preset time if not insert reset timer and of card; When going out, pull out magnetic card and open the door, can break power down source and restart the timer timing, close the door and to close timing alarm, close timer if do not close the door then just give the alarm to remind and close the door to the default time, and the time of design is shorter, and the distance that the people walks can also be heard the sound of alarm and go back to close the door.

Description of drawings

Fig. 1 is an embodiment of the invention power circuit

Fig. 2 is an embodiment of the invention timing and alarming circuit

Fig. 3 is that embodiment of the invention circuit is always schemed

Fig. 4 is the embodiment of the invention total figure in kind (being fit to timber)

Fig. 5 is the embodiment of the invention total figure in kind (being fit to iron gate)

Fig. 6 is embodiment of the invention design logic figure

To closing accompanying drawing the present invention is further described below:

Embodiment is in conjunction with Fig. 1, among the figure: IC ₁It is reflecting photoelectric coupler.Because VT can not receive the infrared light that VD sends, and VT is in by state, in card insertion slot, VT receives the infrared light that is sent by VD, VT conducting, VT generally speaking ₁Manage also saturation conduction, the low level signal of its collector is through VD ₁Add to IC ₂2 pin, make 3 pin be high level.This high level is through R ₅Add to the gate pole of controllable silicon VS, make the VS triggering and conducting, the relay K that is connected in series with it gets electric adhesive, its contact K _1-1Closure, three-core socket XS gets electric, and electrical equipment can normally use on it.When card was plugged, dormitory had electricity always, and transferred to when blocking when going out, because IC ₂Time-lag action is arranged, can not cut off the power supply in the dormitory at once, so that under illumination, leave.

Embodiment, in conjunction with Fig. 2, among the figure: this circuit is 10 seconds countdown circuit that utilize two integrated counter 74LS192 to be concatenated into.Dried spring JAG-K and small magnet YA form shift switching, when they separate, just can start the timer timing, count down to 0 second when the time, and 74LS192 drives 555 circuitorder alarm equipment alarm by AND circuit.

Embodiment, in conjunction with Fig. 3, among the figure: when opening the door, dried spring JAG-K and small magnet YA separate, thereby conducting starts 74LS192 makes its work pick up counting, and Preset Time is 10 seconds, adopts the mode of countdown, when the time arrived 0 second, 74LS192 drove 555 circuitorder alarm equipment alarm by AND circuit; When card is inserted into IC ₁When middle, IC ₁Be reflecting photoelectric coupler spare, at ordinary times, because luminous VD and light-receiving tube VT be in the same side, VT can not receive the infrared light that VD sends, and promptly VT is cut-off state.In the time of in card inserts its groove, VT just receives the infrared light that is sent by VD, VT conducting, VT thereupon ₁(positive-negative-positive) guarantees adequate food and conducting, and the low level signal of its collector is through VD ₁Add to IC ₂2 pin, make IC ₂Upset set makes the monostable circuit conducting of compositions such as ic 555 then, makes the gate pole triggering and conducting that loads controllable silicon VS to get electric adhesive with relay K, K _1-1Closure, the conducting of dormitory power-on circuit; Simultaneously, the voltage of generation makes it reset for resetting voltage of 74LS192.

When the people gos out when extracting card, because IC ₂The time-lag action of monostable circuit, when the no-voltage of the inside, low-level circuit restarts the 74LS192 timing; Close the door and then close timing circuit,, start and report to the police if the timing circuit of not closing the door was then worked up to 0 second always.

Embodiment, in conjunction with Fig. 4, Fig. 4 is that the embodiment of the invention is fit to be installed in the in kind total figure on the timber.

Embodiment, in conjunction with Fig. 5, Fig. 5 is that the embodiment of the invention is fit to be installed in the in kind total figure on the iron gate.

Embodiment, in conjunction with Fig. 6, Fig. 6 is embodiment of the invention design logic figure.Among the figure: when opening the door, timer starts, and the insertion magnetic card starts the power supply electricity consumption, simultaneously timer is resetted, and timer will start alarm to preset time if the card of insertion not close to the doorstep again; When going out, pull out magnetic card and open the door, can break power down source and restart the timer timing, close the door and to close timing alarm, close timer if do not close the door then just give the alarm to remind and close the door to the default time, and the time of design is shorter, and the distance that the people walks can also be heard the sound of alarm and go back to close the door.
