Description

The domestic environment pick-up unit

Technical field the utility model relates to a kind of pick-up unit.

The background technology Smart Home can be defined as a process or a system, utilizes advanced computer technology, network communications technology, comprehensive wiring technology, wireless technology, with the various subsystems relevant with life staying idle at home, organically combines.Compare with common household, change instrument into, omnibearing communication switching function is provided, help family to exchange unimpeded with the outside message that keeps with active intelligence by original passive static structures.Smart Home is emphasized people's subjective initiative, requires to pay attention to the coordination of people and living environment, can indiscriminately ad. as one wishes control indoor living environment.Such as control of Long-distance Control that can be by curtain, air-conditioning, background music, home theater, security alarm, remote monitoring or the like.At present, the most employing within the walls of domestic Smart Home environmental monitoring system connected up, and a complete set of system field engineering comprises curtain, desk lamp, domestic installations such as Indoor Environment Detection.

But popular now Smart Home also has its shortcoming, that is exactly not quick detachable, finishing, easily damaged, and maintenance is very inconvenient, a whole set of intelligent domestic system especially is installed is involved great expense, the omnibearing system of one cover approximately needs the price of hundreds of thousands, room charge for hard-cover this system can be up to up to a million, price be general wage-earners can not bear, so also just can not get very big popularization.

The summary of the invention the purpose of this utility model provides the domestic environment pick-up unit that a kind of cost is lower, the user can be known the information of living environment in real time.

The utility model technical solution problem realizes by the following technical solutions:

A kind of domestic environment pick-up unit.Comprise single-chip microcomputer, sensor, phonetic alarm, gsm module and display module composition; Sensor, phonetic alarm, gsm module and display module are connected with single-chip microcomputer by corresponding I/O interface.Sensor comprises temperature sensor and gas concentration sensor, and temperature sensor adopts DS18B20.Gsm module adopts TC35i.The speech chip of phonetic alarm adopts ISD1420.

During use, sensor carries out the reception of signal to domestic environment, the temperature sensor of sensor and gas concentration sensor are measured temperature and gas concentration respectively, the gas concentration sensor measure portion makes full use of the existing flammable gas alarm device in market, at internal interface wireless transmitter module SC2262, when the concentration over-standard that detects indoor harmful gas, this module passes to single-chip microcomputer with signal by wireless transmit, single-chip microcomputer receives by wireless receiving module SC2272, and vacant phonetic alarm reports to the police, and utilizes gsm module to send help information simultaneously.Daily people can check indoor environmental data now by display module.

Compared with the prior art, the beneficial effects of the utility model are: the temperature in the Intelligent Measurement domestic environment, carbon monoxide gas concentration, fire information, and pass through the transmission that the gsm wireless network technology realizes detecting data.Its design cost is low, and is multiple functional, and the system reliability height is fit to be applied to current Smart Home environmental monitoring system.

Embodiment in spatial structure sketch of the present utility model shown in Figure 1, a kind of domestic environment pick-up unit.Comprise single-chip microcomputer, sensor, phonetic alarm, gsm module and display module composition; Sensor, phonetic alarm, gsm module and display module are connected with single-chip microcomputer by corresponding I/O interface.Sensor comprises temperature sensor and gas concentration sensor, and temperature sensor adopts DS18B20.Gsm module adopts TC35i.The speech chip of phonetic alarm adopts ISD1420.

In temperature survey partial circuit figure of the present utility model shown in Figure 2, utilize temperature sensor DS18B20, single-chip minimum system is realized thermometric function.The digital temperature sensor DS18B20 that this operative sensor adopts American Dallas semiconductor company to produce.Because scene temperature is directly transmitted with the digital form of " one-wire bus ", thereby improved the reliability of system greatly.Single-chip Controlling DS18B20 carries out real-time temperature survey and shows by display module

In flammable gas-detecting alarm device circuit diagram of the present utility model shown in Figure 3, this part is utilized the existing flammable gas alarm device in market, and portion meets wireless transmitter module SC2262 and host computer communicates within it.Gas concentration measurement partly utilizes the existing flammable gas alarm device in market, and portion meets wireless transmitter module SC2262 and host computer communicates within it.Sensor all has higher sensitivity to general inflammable gas (as hydrogen, carbon monoxide, propane, ethanol etc.).This alarm circuit can be exported and measure and alarm control signal, when detecting combustable gas concentrations such as indoor coal gas, rock gas when alarm and exceeding standard, just can trigger SC2262 works on power, the data transmission of establishing is in advance arrived the wireless receiving module SC2272 of host computer, the startup hummer sent warning message after host computer received signal, remind user's corresponding measures such as ventilation of in time taking to window, cause danger avoiding.
