This paper is concerned with the security management system for oilfield based on Embedded wireless communication. The site of oil-well is distributed dispersedly, but distribution area is wide. Oil exhauster continuous working for 24 hours. Regional of Perambulation for the site of oil-well is very vast, meanwhile, as for the problem of petroleum being stolen, transmission line being stolen, transformer being stolen, which has been one of the important objective condition restriction of geographical environment, the implementation of safe management for oilfield is very difficult. We overcome these difficulties, which management works. With Consideration of the comes from geographical environment. The cost is not only high if the fiber cable would be lay between working station in the several tens of square kilometers, but also need to put into a lot of human and material resources with line maintenance and guard against theft. It is a perfect scheme that remote wireless monitoring and control system is established.
