Description

The automatic reminiscences of switch door

(1) technical field

The utility model belongs to technical field of electronic products, relates to the automatic reminiscences of a kind of switch door.

(1) background technology

In the daily life, turnover door regular meeting constantly forgets and close the door or be with key, and is stolen easily or do not open door, brings very big inconvenience to people.

(2) summary of the invention

The utility model is forgotten when solving inlet/outlet and is closed the door or with the problem of key, provide a kind of switch door automatic reminiscences.

The utility model is achieved by the following technical solution: the automatic reminiscences of a kind of switch door comprises that being installed in the interior door leaf of doorframe pushes up along last magnet steel, is installed in the automatic reminiscences Circuits System of pressure transducer, loudspeaker, contactor and switch door on the door handle.

The automatic reminiscences Circuits System of switch door comprise dry reed switch K, transistor V1, transistor V2,555 monostable circuit IC1, with a door AND1, with a door AND2, pressure pulse device 1, speech simulation integrated circuit (IC) 2, speech simulation integrated circuit (IC) 3, loudspeaker B, not gate NOT.

The two ends of described dry reed switch K are connected with emitter with transistor V1 base stage; The collector of transistor V1 is connected with the input end 2 of 555 monostable circuit IC1; The output terminal of 555 monostable circuit IC1 with door AND1, AND2 separately one of input end be connected jointly, pressure pulse device 1 output terminal be connected with another input end of door AND2, the pressure pulse device 1 also input end of Sheffer stroke gate NOT connects, the output terminal of not gate NOT be connected with another input end of door AND1; With the output terminal of door AND1 be connected in speech simulation integrated circuit (IC) 2 input end, with the door AND2 output terminal be connected in speech simulation integrated circuit (IC) 3 input ends; The output terminal of speech simulation integrated circuit (IC) 3, speech simulation integrated circuit (IC) 2 is connected in the base stage of transistor V2 jointly, and loudspeaker B is connected on the collector of transistor V2.

Be equipped with pressure transducer in the described pressure pulse device, be installed on the door handle, when hold with a firm grip during door handle, sensor output signal is a high level.

Save as " please door being shut " voice analog signal in the speech simulation integrated circuit (IC) 2; Save as " please be with key " voice analog signal in the speech simulation integrated circuit (IC) 3.

The beneficial effects of the utility model are:

1. " please door being shut " voice suggestion can be arranged when opening the door; When at closing time, the voice suggestion of " please with good key " can be arranged.Can play the effect of timely prompting.

2. simple in structure, convenient and practical, suitable applying.

(4) description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is the circuit diagram of the automatic reminiscences Circuits System of switch door;

1 pressure pulse device among the figure, 2 pressure pulse devices.

(3) embodiment

Accompanying drawing is the circuit diagram of internal circuitry of the present utility model, below in conjunction with description of drawings.

The automatic reminiscences of a kind of switch door, comprise be installed in door leaf top in the doorframe along last magnet steel, be installed in pressure sensor device on the door handle, be installed in the automatic reminiscences Circuits System of loudspeaker, reminiscences switch and switch door on the doorframe.

Dry reed switch K is connected with transistor V1 base stage in the automatic reminiscences Circuits System of switch door as shown in Figure 1; The collector of transistor V1 is connected with the input end 2 of 555 monostable circuits; The output terminal of 555 monostable circuits with door AND1, AND2 separately one of input end be connected jointly, pressure pulse device 2 output terminals be connected with another input end of door AND2, the input end of pressure pulse device 1 Sheffer stroke gate NOT connects, the output terminal of not gate NOT be connected with another input end of door AND1; With the output terminal of door AND1 be connected in speech simulation integrated circuit (IC) 2 input end, with the door AND2 output terminal be connected in speech simulation integrated circuit (IC) 3 input ends; The output terminal of speech simulation integrated circuit (IC) 3, speech simulation integrated circuit (IC) 2 is connected in the base stage of transistor V2 jointly, and loudspeaker B is connected on the collector of transistor V2.

Principle of work of the present utility model is: when the people pushes when entering, door is opened, and dry reed switch is because the effect of magnet steel is opened, and the V1 conducting triggers monostable circuit IC1 output high level.This moment, the people did not hold door handle, so the time pressure apparatus 1 low level input, through not gate output high level, import simultaneously with door AND1 with the high level of IC1 output and to obtain a high level.Make speech simulation integrated circuit (IC) 2 output sound signals,, send the prompt tone of " please door being shut " through loudspeaker B.

When the people gos out, hold moving door handle, pressure transducer output high level.When Men Gang is opened, dry reed switch is opened, the V1 conducting triggers monostable circuit IC1 output high level, import AND2 jointly with the high level of sensor output, the output high level, make speech simulation integrated circuit (IC) 3 output sound signals,, send the prompt tone of " please with good key " through loudspeaker B.

When door was closed, tongue tube was subjected to the effect closure in magnet steel magnetic field, and transistor V1 base earth ends, the IC1 output low level, and this moment, IC2, IC3 all were not triggered, and transistor V2 ends, and loudspeaker does not take place.

When there being the people frequently to come in and go out within doors, when not needing voice reminder, can circuit disconnect switch.
