Fig. 2 is the circuit theory diagrams of phonetic warning unit.
Wherein, 1---speech trigger circuit, 2---accumulator.
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 LED fluorescent writing board, loudspeaker, speech chip, speech trigger circuit, sensor and accumulator.Accumulator is that LED fluorescent writing board and phonetic warning unit are powered.The input end of the output termination speech trigger circuit of sensor, the input end of the output termination speech chip of speech trigger circuit, the input end of the output termination loudspeaker of speech chip.Accumulator is LED fluorescent writing board and power speakers.
In embodiment 1, sensor is infrared reflection type detecting sensor, and speech chip is AP8910A type speech chip.In embodiment 1, loudspeaker, speech chip and speech trigger circuit form phonetic warning unit jointly, see Fig. 2.
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.
LED fluorescent writing board (LEDwritingboard) has another name called electronic fluorescent screen, led fluorescent plate, led luminous plaque etc., be made by electrophoresis aluminum alloy frame and the guide-lighting face glass of high brightness electronics, with fluorescence water-color paintbrush directly Writing-painting on the guide-lighting face glass of electronics, can be erasable arbitrarily.Brilliant gorgeous effect can be presented after the energising of LED fluorescent writing board.LED fluorescent writing board has the advantages such as energy-saving and environmental protection, luminous well-balanced and service time is long, and content pattern can change the sensation of finding everything fresh and new to people at any time.
Signal input part S1 ~ the S4 of AP8910A type speech chip is all triggered by high level, and signal input parts different in triggering voice chip U3 can report 4 section audios of different content.
The course of work of embodiment 1 is: in speech chip, arrange phonetic warning contents such as " Keep Clear-High Voltage please don't be close " in advance, utilizes fluorescence water-color paintbrush Hand writing or drafting on LED fluorescent writing board to warn word or figure.Infrared reflection type detecting sensor spatial emission infrared ray towards periphery, personnel enter in sensing range, and infrared reflection type detecting sensor exports high level to speech trigger circuit, and phonetic warning play by speech chip control loudspeaker.
embodiment 2
With reference to Fig. 1, in the composition of embodiment 2 except sensor, all the other are all identical with embodiment 1.In embodiment 2, sensor is microwave remote sensor.Microwave remote sensor is the device utilizing microwave property to carry out detecting physical quantities, comprises the existence of sense object, detects movement velocity, Distance geometry angle.The principle of work of microwave remote sensor is as follows: the microwave sent by emitting antenna, will be absorbed or reflect, power is changed when running into testee; Utilize receiving antenna to receive by testee or the microwave that reflected by measured object, and convert it to electric signal, then by metering circuit process, just achieve microwave and detect.Microwave remote sensor is primarily of microwave oscillator and microwave antenna composition.Microwave oscillator is the device producing microwave.The device forming microwave oscillator has klystron, magnetron or solid-state components.The oscillator signal produced by microwave oscillator need use waveguide transmissions, and is gone out by antenna transmission.In order to make the microwave of transmitting have consistent directivity, antenna should have special structure and shape.Microwave remote sensor has that reaction velocity is fast, sensitivity is higher, induction region is wide, security stability is high, is not subject to the advantage that temperature, air-flow, dust and smog etc. affect.Embodiment 2 uses the micro loop antenna of diameter 9 centimetres to do microwave sounding, this tours antenna adopts the sub-thread copper conductor of 5 ~ 10cm to make, and this tours antenna produces at axis direction the oval Space Microwave guard district that a radius is 0 ~ 5 meter (this radius is adjustable).The echo of its reflection when physical activity and source microwave field (or frequency) interference that sends of microwave remote sensor and change.Time static, the output terminal of microwave remote sensor is low-voltage; Time dynamic, human body from antenna more close to, the output voltage of microwave remote sensor is higher, reaches as high as 10V.
The course of work of embodiment 2 is: in speech chip, arrange phonetic warning contents such as " Keep Clear-High Voltage please don't be close " in advance, utilizes fluorescence water-color paintbrush Hand writing or drafting on LED fluorescent writing board to warn word or figure.Red microwave remote sensor is spatial emission microwave field towards periphery, and personnel enter in sensing range, and microwave remote sensor exports high level to speech trigger circuit, and phonetic warning play by speech chip control loudspeaker.
