Embodiment
As shown in Figure 1, the utility model mainly is made of main frame 1, supporter 2, infrared transmitter 3, infrared receiver 4, active desktop 5, table body 7, multifunction book shelf 6.Infrared transmitter herein adopts infrared light-emitting diode, and supporter 2 and table body 7 are formed in one.The two ends of active desktop 5 are placed on the slideway 8 on the body, main frame 1 is arranged on a side of multifunction book shelf 6, the front end of active desktop 5 is pressed close to the lower shoe of multifunction book shelf 6, front and back push-and-pull active desktop 5, it is adjusted to suitable position, sits up straight when preceding people's head with human body and do not block infrared light-emitting diode 3 and be as the criterion with the monitoring net that infrared receiver 4 forms.Infrared light-emitting diode 3 in the transmitter unit 11 and the infrared receiver 4 in the receiving element 12 are separately positioned on the supporter 2 of desk both sides near a side of human body, are up and down and arrange, and link to each other with main frame 1 by lead respectively.The following end distance active desktop 5 general 10～15cm of infrared light-emitting diode 3 and infrared receiver 4, about last end distance active desktop 5 general 40cm, like this, between infrarede emitting diode 3 and infrared remote receiver 4, formed up and down the infrared observation net of two levels, middle two intersections.When human body is sat up straight, can not block, blocking-up infrared ray light path, bow and work as the people, bend over or will block light path when lying prone on desk, main control unit 10 cycle controls and detection four road photosignals, be blocked when having detected signal, pick up counting, if light path recovers unimpeded in the time of program setting, main frame 1 just can not send acousto-optic and remind, otherwise main frame 1 is controlled acousto-optic reminding unit 13 respectively by output interface and is made the pilot lamp flicker and send the voice reminder signal, if remind three signals still to be blocked continuously, 10 of main control units are controlled output control unit 14 automatically, cut off the supply socket 9 of external light source, open power supply again after waiting to rectify sitting posture.In circuit theory diagrams shown in Figure 3, supply socket 9 usefulness PLUG1 represent.
As shown in Figure 3, the circuit theory diagrams of an embodiment of the present utility model have been provided.Main control unit 10 is single-chip microcomputer 89C2051; Transmitter unit 11 comprises two infraluminescence pipe D3, D4; Receiving element 12 comprises two infrared receiver IC2, IC3, and infrared receiver adopts SM3381 in the present embodiment.Acousto-optic reminding unit 13 comprises a recording playback sound chip IC 1, adopts ISD1420 sectional recording chip in this example, also comprises recording switch KEY1, microphone MIC1, loudspeaker SPEAKER1, light emitting diode D5.Output control unit 14 comprises relay J 1 and supply socket PLUG1.The negative terminal of infraluminescence pipe D3, D4 is linked together by resistance R 13 ground connection, anode is connected respectively to the collector of triode BG1, BG2, the base stage of triode BG1, BG2 is connected to port one 9 pin and 18 pin of single-chip microcomputer 89C2051 respectively by resistance R 15, R14, two triodes are used for the amplifying emission signal.4 pin of the signal output part IC2 of two infrared receivers and 4 pin of IC3 by IC4A, IC4C and IC4B, IC4D shaping after, be connected respectively to port 9 pin, 11 pin of single-chip microcomputer 89C2051.Single-chip microcomputer 89C2051 control infrared light emission pipe D3, the D4 timesharing takes turns conducting, when infrared ray light emitting diode D3 conducting, two infrared ray light paths between infrared light-emitting diode D3 and infrared receiver IC2 and IC3, have been formed, when infrared ray light emitting diode D4 conducting, between infrared light-emitting diode D4 and infrared receiver IC2 and IC3, formed two other infrared ray light path, like this, at infrared light-emitting diode D3, D4 and infrared receiver IC2, just formed the infrared ray light path of four timesharing conductings between the IC3, single-chip microcomputer 89C2051 detects infrared receiver IC2, the output state of IC3, so circulation.When human body enter as shown in Figure 1 infrared light emitting diode 3 and infrared receiver 4 between the time, certain of four light paths is blocked, cause that simultaneously 9 pin of single-chip microcomputer 89C2051 and the input state of 11 pin change, the timer internal of single-chip microcomputer 89C2051 picks up counting, light path recovers unimpeded in the time of program setting, main frame 1 just can not send acousto-optic and remind, otherwise, main control unit 10 is by the light emitting diode D5 flicker of the 15 foot control system acousto-optic reminding units 13 of single-chip microcomputer 89C2051, send light prompt, the recording chip IC1 of 17 foot control system acousto-optic reminding units 13 by single-chip microcomputer 89C2051, make loudspeaker SPERKER1 play the voice reminder signal that records in advance, still be blocked for three times if remind continuously, 10 relay J 1 of main control unit by the 14 foot control system output control units 14 of single-chip microcomputer 89C2051, the normally closed contact J1-2 of relay J 1 is disconnected, cut off the power supply of output control unit external light source socket PLUG1, open power supply again after waiting to rectify sitting posture.
In the aforementioned structure, the adjustable positions of desktop, and the position of supporter is fixed, certainly, the supporter that will have locking device is contained on the slideway, and with the desktop fixed installation, or on the table body two slideways being arranged, desktop and supporter are contained in the effect of the adjustment position relation that also can reach same in two slideways respectively.
Certainly, the also available controllable silicon of the relay in the output control unit replaces, and the also available bulb of the light emitting diode D5 of acousto-optic reminding unit 13 replaces, and these are all at the row of protection of the present utility model.
