Description of drawings:

Fig. 1 is the utility model desk schematic diagram.

Fig. 2 is the utility model control circuit structural representation.

Number in the figure: 1 desk front side board, 2 is gone into to sit signal detection probe, 3 altitude signal detection probe, 4 desk lamps and is subjected to unthreaded hole, desk desktop, 6 desk lamps.

Below, in conjunction with the accompanying drawings the utility model is further described by the specific embodiment.

The specific embodiment:

Referring to Fig. 1, Fig. 2, supporting desk and the control circuit of being provided with, control circuit comprises: go into to sit boot-strap circuit, height detection circuit, timing circuit, sound circuit, lamp control circuit and automatic shutdown circuitry, wherein:

Go into to sit boot-strap circuit, pop one's head in 2 with the infrared transmitting tube DU1 and the infrared reception DU2 pipe that are arranged on the desk front side board 1 for going into to sit signal detection, detection signal one tunnel is as timing circuit timing triggering signal, and another road is as going into to sit the suggestion voice triggering signal; IC3:NE555 forms the time-base oscillation circuit, amplifies through V12, and control DU1 transmitting tube emission infrared pulse signal, DU2 and V13, V14, V15, V16, V18 form infrared radiation receiving circuit.The relative distance of DU1 and DU2 is 5cm.After the user went into to sit, DU1 emission infrared signal was received by DU2, makes receiving circuit work.And the control speech chip sends suggestion voice and " for eye health, please notes sitting posture ".

The height detection circuit is an altitude signal detection probe 3 with a pair of infrared transmitting tube DU3 and the infrared receiving tube DU4 that is arranged on the desk desktop 5, and detection signal is as sitting posture suggestion voice triggering signal.IC2:NE555 forms the time-base oscillation control circuit, amplifies control DU3 emission infrared pulse signal through V11.DU4 and V10, V9, V8, V7 form receiving circuit, and the relative distance of DU3 and DU4 is 5cm.When eyes are lower than desktop 30cm, because DU4 receives the infrared signal from DU3, make the work of DU4 receiving circuit, the control speech chip sends suggestion voice, " for eye health, please noting sitting posture "

Timing circuit, base chip and its peripheral cell are formed the clock control delay circuit during IC4:NE555, and output signal is as overtime suggestion voice triggering signal;

Lamp control circuit, to be subjected to the photosensitive tube Rz in the unthreaded hole 4 be the environment bright detection means to be arranged on desk lamp, through circuits for triggering, is illuminating device with the array-type LED pipe that is arranged in the output power amplifier;

Automatic shutdown circuitry serves as the shutdown triggering signal to be arranged on the reflected signal that infrared receiving tube DU2 in the seat boot-strap circuit do not receive infrared transmitting tube DU1.

Shown in Figure 2, power circuit: 220V voltage is exported two-way voltage through power transformer T step-down output 15V alternating voltage after diode rectification filtering, one the tunnel gives the power supply of LED desk lamp, one the tunnel exports 5V voltage after the IC1 voltage stabilizing gives the power supply of " desk " circuitry, IC1 is the three-terminal voltage-stabilizing chip, and output 5V voltage is the control circuit power supply.IC2, IC3, when IC4 is monostable the base chip, wherein:

The base chip was formed pulse oscillator with resistance R 22, R23, C18 when IC3 was NE555,, amplified control DU1 emission infrared pulse signal by its 3 pin voltage pulse output through V12.

After DU1 and DU2 are blocked by the person simultaneously, tube-launched infrared signal is received by DU2 after the human body reflection, the V13 base stage must be conducted, make the V16 conducting, V14, V15 conducting in succession, V15 colelctor electrode output high level divides two-way, and one the tunnel makes the V18 conducting through R32, R33, V18 colelctor electrode output high level through R15 to speech chip IC5.A pin by IC5 triggers the work of IC5 internal circuit, sends suggestion voice: " for eye health, please note sitting posture! ", circuit supplies such as IC2, IC4, IC5 are given on another road simultaneously.

IC5 is a speech chip, is the complete speech chip of disposable burning, and Y is combined into sound circuit with loudspeaker.

The operation principle of IC2 is identical with the IC3 operation principle.

After DU3, DU4 are blocked by person position, lie prostrate when the tabletop reading, writing such as the envoy, when face is lower than desktop 30cm with head portion or health a part, DU4 will receive the infrared signal that DU3 reflects, and make the V10 conducting, the V9 conducting, V8, V7 conducting in succession, V7 colelctor electrode output high level makes IC5 send suggestion voice through the A of R15 to IC5 pin: " for eye health, please note sitting posture! "

RZ is photo resistance, and during the high light line, RZ is low resistance, makes the V1 conducting, and V2, V3 end, and the LED luminous tube must not work by electricity.During decreased light, make RZ be high value, the V1 base voltage is very low, and V1 ends, the V2 conducting, and the V3 conducting, the LED luminous tube gets electric lighting.Desk lamp 6 adopts the LED lamp, is made up of 30-40 White LED luminous tube, and low-voltage is lighted, radiationless, no stroboscopic, non-stimulated, useful especially to eye protection.

IC4 is the NE555 chip, formed delay control circuit with peripheral cell R9, R10, C13, when IC4 get electric after, 2,6 pin voltages begin to be lower than 2/3 volt of supply voltage, 3 pin of IC4 are output as high level, V4, V5 and V6 are ended, along with R9, R10 charge to capacitor C 13, after after a while, C13 is filled, make the voltage of its 2 pin, 6 pin be higher than 2/3 volt of supply voltage, make the V6 conducting, for C13 provides discharge channel.One the tunnel makes the V4 conducting, and V4 emitter stage output high level to the B pin of speech chip IC5, makes circuit working in the IC5, sends suggestion voice: " for eye health, please take a momentary rest! "

Function of use comprises:

1, when the user went into to sit, health desk had voice suggestion: ", please noting sitting posture " for eye health, and enter following duty automatically.

2, when visual range less than health with eye distance from, during such as 30cm, voice suggestion is arranged: ", please note sitting posture for eye health.”

3, when continuous learning time reaches 1 hour, voice suggestion is arranged: ", please take a momentary rest for eye health! "

4, when light secretly when being not suitable for reading and writing, desk lamp is lighted automatically on the desk.

5, after the people left desk, above function was closed automatically.
