Invention main points of the present utility model just are to use distributed WSN technique construction distributed wireless weather station.This weather station is system (SoC) the technology configuration node micro power consumption wireless transducer that utilizes on the single-chip microcomputer sheet, adopt distributed WSN technology, just can gather various meteorological elements easily being in the regional extent of center, radius 200m with the centre data processor.Then, utilize GPRS/CDMA and technique of internet, the meteorological element state information that is distributed in GPRS/CDMA and the internet institute coverage is gathered, handled and uploads, with the data message of analyzing as weather forecast.
In such scheme, the meteorological element that node micro power consumption wireless transducer is used for being gathered converts the various signals of telecommunication to, and finish signal processing, and then carry out the data information exchange communication by wireless mode and centre data processor, the centre data processor is according to the requirement of " the ground observation standard " of meteorological department's formulation, the meteorological data of uploading to each node micro power consumption wireless transducer is handled, be connected by the GPRS/CDMA communication module or with the internet, realize the weather information transmission in the broad regions scope thus.
Between node micro power consumption wireless transducer in the utility model and the centre data processor owing to be to carry out in-plant regional wireless telecommunications by wireless communication module, do not have the connection of communication cable, thereby system have the ability and the rodent-proof characteristic of the thunderbolt of well anti-induction thunder; And each node micro power consumption wireless transducer can carry out indoor calibrating simultaneously with collector, thereby troubleshoot system errors preferably; Owing to be to adopt the close range wireless communication networking, node micro power consumption wireless transducer and centre data processor are powered by solar power supply apparatus, and be suspension ground connection, thereby lay conveniently, can exempt required expenses such as wiring, earth mat engineering, shielding and preventive measure against rats, cost and failure rate all can significantly reduce, and have saved pork barrel.
Below in conjunction with accompanying drawing the utility model is further described.
