The utility model has following beneficial effect: prior art of comparing, and the utility model passes through first processor and second processor of setting; The input end of first processor is connected to sound transducer, smoke transducer, air mass sensor, clock chip, temperature sensor and relay; The output terminal of first processor connects the input end of speech chip, the first display and the second processor respectively; The output terminal of the second processor does not connect second display and the relay for controlling first processor and sensor; Speech chip output terminal is connected with loudspeaker; Control by adopting first processor and the second processor, can realize making monitoring to harmful gases such as methane common in environment temperature, humidity, air, ammonia, aromatic compounds, sulfide, benzene series steam, smog through air mass sensor, warning can be sent by the speech chip being connected with loudspeaker after harmful gas being detected, and can after monitoring harsh noise, send voice message, be therefore more applicable for detection and the management of indoor public environment order.
Further, because device is also connected with infrared remote control module, make it more convenient in practical process.
Accompanying drawing explanation
Fig. 1 is this apparatus structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, the utility model comprises first processor; The input end of first processor is connected to sound transducer, smoke transducer, air mass sensor, clock chip, temperature sensor and relay; The output terminal of first processor connects the input end of speech chip, the first display and the second processor respectively; The output terminal of the second processor connects second display and the relay for controlling first processor and sensor respectively; Speech chip output terminal is connected with loudspeaker.First processor is STC12C5A60S2 single-chip microcomputer; Second processor is STC89C52 single-chip microcomputer.It is serial communication between first processor and the second processor.Speech chip is ISD1760 speech chip; Clock chip is DS1302 clock chip; Temperature sensor is DS18B20 temperature sensor.First display is LCD12864 liquid crystal display; Second display is 16*64 dot matrix screen.The input end of the second processor is also connected with the infrared remote receiver for receiving instruction, and the model of infrared remote receiver is HX1838.Be provided with AD conversion chip between smoke transducer and first processor, and AD conversion chip model is PCF8591.
The course of work: smog is passed sensor, sound transducer, air mass sensor when external information being detected just can in time by information feed back to first processor process.The numerical value of the numerical value received and storage is compared by first processor.
1) detection of environmental order signal: mainly monitoring is indoor air quality, comprises the harmful gases such as formaldehyde, methane, sulfide, smog.Information sensor feedback come is through first processor process, and according to these feedback informations, first processor can control speech chip ISD1760 and play corresponding voice message language.
2) speech play realizes:
First processor judges according to the information of each sensor feedback, then the broadcasting that speech chip ISD1760 carries out signal language is controlled, the voice content needing to play is recorded in advance in speech chip, play during as monitored cigarette combustion thing " in order to your my health; please don't smoking in public ", monitor when someone makes a racket play: " please don't make a racket in public ", monitor air quality poor time play: " IAQ (indoor air quality) is poor, ventilation of please windowing in time ".The monitoring of air quality can monitor the content of some harmful gas in air, the methane gas produced after such as natural gas leaking, the formaldehyde gas etc. produced in house decoration process.Then the gas signal collected is carried out AD converter conversion to be then presented on LCD12864 liquid crystal display for people's reference.
3) screen display realizes:
Better point out effect to have, adopt 16*64 dot matrix display screen to carry out Subtitle Demonstration, dot matrix screen shows current time at ordinary times, toggle screen display at once after cigarette combustion thing being detected: the printed words of " no smoking "; Show when monitoring noise: the printed words of " quiet, please "; Show when air quality is poor: " ventilation of please windowing in time ".Dot matrix display screen adopts the second processor STC89C52 Single-chip Controlling, and the displaying contents of dot matrix controls by first processor single-chip microcomputer STC12C5A60S2.
On LCD12864 screen, displaying contents has: current time, air gas parameter sampling value, air quality net assessment (good, general, poor), forbids the prompting captions that make a racket, no smoking.Displaying contents is divided into three screen displays, and each screen carries out with 5 second time as interval switches.Monitor the signal language that noise is relevant with display during smoke signal.
Control by adopting first processor and the second processor, can realize making monitoring to harmful gases such as methane common in environment temperature, humidity, air, ammonia, aromatic compounds, sulfide, benzene series steam, smog through air mass sensor, warning can be sent by the speech chip being connected with loudspeaker after harmful gas being detected, and can after monitoring harsh noise, send voice message, be therefore more applicable for detection and the management of indoor public environment order.
