Description

A kind of infrared welcome's device

Technical field:

The utility model relates to a kind of electronic installation, especially a kind of infrared welcome's device.

Background technology:

Many units such as hotel, market, restaurant etc. are in order to improve service quality, one of the porch of management place special configuration or several attendants, this part cost is very big, and be cold or heat the attendant be difficult to stand, so the welcome attendant to be replaced by welcome's device will be inexorable trend.At present, its circuit design of voice welcome device of Xiao Shouing is very complicated on the market, the production cost height, and often occur broadcasting bad phenomenon such as ushering in and out diction, so the actual popularization of this class device difficulty is very big. by mistakeAnd the utility model relates to a kind of infrared welcome's device, and its circuit design is simple, and production cost is low, and is very practical.

The utility model content:

The purpose of this utility model provides a kind of infrared welcome's device just in the deficiency that overcomes above-mentioned prior art, a kind of low-cost infrared welcome's device simple in structure; It can realize the automatic speech playing function, and its circuit design is very simple, can survey the guest of the management place of coming in and going out constantly, and plays greeting.

Realize that the technical scheme that the utility model purpose is adopted is: a kind of infrared welcome's device, it comprises housing (1), circuit board (2), transducer (3,4), loud speaker (5), power socket (6), circuit board (2) is installed on housing (1) inside, loud speaker (5) is arranged at housing (1) front portion, power socket (6) is arranged at housing (1) sidepiece, it is characterized in that: described transducer (3,4) is an infrared sensor.

Description of drawings:

Below in conjunction with drawings and Examples further to the utility model explanation.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a circuit diagram of the present utility model.

Among the figure, 1. housing, 2. circuit board, 3. transducer, 4. transducer, 5. loud speaker, 6. power socket.

Embodiment:

As shown in Figure 1, a kind of infrared welcome's device, it comprises housing (1), circuit board (2), transducer (3,4), loud speaker (5), power socket (6), circuit board (2) is installed on housing (1) inside, loud speaker (5) is arranged at housing (1) front portion, and power socket (6) is arranged at housing (1) sidepiece; Described transducer (3,4) is an infrared sensor.

Described housing (1), its shape can be humanoid, adopt doll's shape at this embodiment, and it can be formed by plastic material or other material.

Described power socket (6) can connect the 220V alternating current.

As shown in Figure 2, a kind of infrared welcome's device, its circuit part are characterised in that it is made of passive infrared sensor DSE1, DSE2, NAND gate integrated circuit (IC) 1, voice integrated chip IC2, resistor R 1 ~ R3, capacitor C1 ~ C3, diode VD1 ~ VD5, triode VT1, VT2, loud speaker B1, B2, inductance coil L1, L2, change over switch K, mains switch SB.Diode VD2 ~ VD5, inductance coil L1, L2 and capacitor C3 constitute power circuit in the wherein empty frame, and this circuit can become the 220V civil power 5V voltage stabilizing direct current, and directly are the local circuit power supply; NAND gate integrated circuit (IC) 1 is selected CD4011BP four NAND gate integrated circuits for use, when infrared ray transducer DSE1, DSE2 have detected people's activity, the drop-down level of its OUT end output 10 seconds, this signal is handled and corresponding output two-way high trigger signal L, R through IC1, trigger end L, R are electrically connected with IC2 by change over switch K, the corresponding voice memory unit of IC2 is touched and is sent corresponding voice by loud speaker B1, B2, as " welcome! ", " thanks your patronage, welcome to come again! " wait friendly voice reminder, the pre-storage of IC2 output melody when DSE1, DSE2 sounding, the melody that loudspeaker plays is beautiful is to attract client.

When pressing change over switch K, the utility model can be positioned over the left side of door and use in this embodiment, and use on the right that then can be positioned over door not according to change over switch K the utility model, and it is very easy to use to utilize change over switch K to switch the induction direction.
