Accompanying drawing explanation
Fig. 1 is composition logic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
embodiment 1
With reference to Fig. 1, embodiment 1 comprises word alarm unit, phonetic warning unit, control module, contactless detection cell and accumulator.Accumulator is word alarm unit, phonetic warning unit, control module and contactless detection cell are powered.The input end of the output termination control module of contactless detection cell, the output terminal of control module connects the input end of word alarm unit and phonetic warning unit respectively.In embodiment 1, contactless detection cell is infrared reflection type detecting sensor.Control module comprises microprocessor and the touch-screen with microprocessor two-way communication, the output terminal of the input termination infrared reflection type detecting sensor of microprocessor.Word alarm unit is LED display, and phonetic warning unit is loudspeaker, the output terminal of the input termination microprocessor of LED display and loudspeaker.
Infrared reflection type sensor is a kind of infrared emitting, receiving device of integration, its inside comprises infrared emitting, reception and signal and amplifies and treatment circuit, the human body in the certain limit of front can be detected with non-contacting form, and convert high level signal output to.Infrared reflection type sensor internal have employed low energy-consumption electronic device and anti-jamming circuit, and working stability is reliable.The operating voltage of infrared reflection type sensor is 5 ~ 12V, and limiting voltage is 15V, and working current is 5 ~ 20mA, and maximum operating currenbt is 30mA, and corresponding detecting distance is 0 ~ 120 ㎝.After infrared ray reflection sensor switches on power, the modulated infrared of 38KHZ forwards launched by the infrared reflection pipe of its inside, once there be object or person body to enter in effective range, infrared ray will some be reflected back, to be received and after converting the electric signal of same frequency to arranging the photosensitive receiving tube installed by with power valve, undertaken amplifying by its internal circuit, demodulation, shaping and after comparing process, its output terminal provides high level signal.Detecting distance and the operating voltage of infrared reflection type sensor are closely related.Operating voltage is higher, and infrared reflection power is stronger, and detecting distance is far away; Otherwise voltage is low, detecting distance is just relatively near.
The course of work of embodiment 1 is: utilize touch-screen to need the word warning content of display and the phonetic warning content of broadcasting to microprocessor input, LED display shows warning word in long bright mode; Infrared reflection type detecting sensor spatial emission infrared ray towards periphery, personnel enter in sensing range, infrared reflection type detecting sensor exports high level to microprocessor, Microprocessor S3C44B0X LED display shows warning word in the mode shone, and phonetic warning play by Microprocessor S3C44B0X loudspeaker simultaneously.The flicker duration of warning word and phonetic warning playing duration all realize setting microprocessor by touch-screen, and adjustable.
