China's economic is fast development these years, and petrochemical industry industry is as mainstay of the national economy industry, and the development of national economy is played vital effect.But it is inflammable, explosive, poisonous, harmful that the raw material of petrochemical industry and product mostly are, and the production process many places are in high temperature, high pressure or the harsh conditions such as low temperature, negative pressure.In a single day petrochemical industry has an accident, and will bring serious threat to people's the security of the lives and property.On July 16th, 2011, the breaking out of fire of Dalian China Petrochemical Industry, 500,000,000 yuan of direct losses; On September 7th, 2010, together Inclination Accident occurs in No. three platforms of China Petrochemical Industry's Shengli Operation, causes 36 people in danger, 5,920,000 yuan of direct economic losses; The two benzene factories of Jiization in 2005 explosion accident causes 8 people dead, and 60 people are injured, 6,908 ten thousand yuan of direct economic losses, and the 100 tons of benzene pollutants of having an appointment flow into the Song Hua River water body, initiation water pollution in Songhuajiang River event; Chongqing Kaixian gas blowout accident in 2003 causes 243 people dead because of hydrogen sulfide poisoning, and 65000 people are settled by emergency evacuation, and direct economic loss reaches 6432.31 ten thousand yuan.Similar accident occurs these years frequently, has caused national great attention, and how taking precautions against and administer disaster is the problem that instantly must face.
And present stage is to the monitoring under these environment or the artificial monitoring of employing, the employing wireless senser, but applied wireless communication technique mostly is greatly Zigbee, bluetooth, infrared, WIFI, these communication distances can be too not far away, the data that the such words transducer collects are difficult to be sent on the hazardous environment server in addition, in order to address this problem, the utility model is attached to one with GPRS telecommunication technique and the Zigbee telegon of maturation, like this with regard to good this problem that solved, the Zigbee telegon gathers the data that the sensor node in the own network collects, then pass through GPRS network, be sent on the server at a distance with the ICP/IP protocol form at last, thereby realized remote monitoring to hazardous environment.
Summary of the invention
The purpose of this utility model is, overcomes the existing restriction of Zigbee wireless communication technique on transmission range, and a kind of Long-range Data Transmission method is provided, and for this reason, adopts following technical scheme:
A kind of wireless sensor network gateway comprises Master control chip, liquid crystal touch screen, Zigbee telegon, GPRS communication module and the interface (USB interface, SD card interface, Ethernet interface, serial ports) that some are commonly used.The Zigbee transducer acquisition node of shedding away sends to the data that collect on the Zigbee telegon of this gateway, and carries out data by Master control chip and process, and then sends on the server terminal in a distant place by the GPRS module; Meanwhile, when our remote server is wanted Zigbee transducer acquisition node controlled accordingly, also can pass through ICP/IP protocol, send on this wireless sensor network gateway via GPRS network again, the Master control chip basis receives concrete content-control Zigbee telegon, and then the acquisition node of controlling under this Zigbee network moves accordingly.This device is played the part of the role of a wireless sensor network gateway in whole process, data are changed between Zigbee protocol format and ICP/IP protocol form.
As preferred implementation, of the present utility model, described processor is the S3C6410 processor of ARM11 framework; Described Zigbee telegon has used the CC2530 chip of TI company; Described GPRS module has adopted the PTM100 mobile module.
