Continuous Working

The area of the oilfield is much wider. Oil exhauster continuous working for 24 hours. As the problem of petroleum being stolen, transmission line being stolen, and transformer being stolen exists which requires the strong secures management system. With Consideration of the objective condition restriction of geographical environment, the implementation of safe management for oilfield is very difficult. We overcome these difficulties, which 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. The system is required to manage the data received from the various site and providing the security by managing and providing automatic controlling structure.

In order to cut cost and simplify redevelopment, the paper proposes a new design for monitoring and control system in active magnetic bearing. Data sampling and processing module is separated with data display module. Singlechip processor is used to sample data from the DSP controller, and processes the data into the needed form. A touch-screen only for display takes on the processed data to customers. The design makes the systems easy to develop and shrink the cost to one tenth of previous design.

Low-power wireless mesh networks (LPWMNs) have been widely used in wireless monitoring and control applications. Although LPWMNs work satisfactorily most of the time thanks to decades of research, they are often complex, inelastic to change, and difficult to manage once the networks are deployed. Moreover, the deliveries of control commands, especially those carrying urgent information such as emergency alarms, suffer long delay, since the messages must go through the hop-by-hop transport. Recent studies show that adding low-power wide-area network radios such as LoRa onto the LPWMN devices (e.g., ZigBee) effectively overcomes the limitation. However, users have shown a marked reluctance to embrace the new heterogeneous communication approach because of the cost of hardware modification. In this article, we introduce LoRaBee, a novel LoRa to ZigBee cross-technology communication (CTC) approach, which leverages the energy emission in the Sub-1 GHz bands as the carrier to deliver information. Although LoRa and ZigBee adopt distinct modulation techniques, LoRaBee sends information from LoRa to ZigBee by putting specific bytes in the payload of legitimate LoRa packets. The bytes are selected such that the corresponding LoRa chirps can be recognized by the ZigBee devices through sampling the received signal strength. Experimental results show that our LoRaBee provides reliable CTC communication from LoRa to ZigBee with the throughput of up to 281.61 bps in the Sub-1 GHz bands.

Sensor Monitoring

For the insufficient of the present monitoring and control system of the crane in communication mode, monitoring data and data is stored; the system of gantry crane safety monitoring and control based on S3c6410 ARM11 is designed in this paper. The Zigbee wireless networking is used to collect and deal with the distributed sensor monitoring, and it can find the problems and to control in the shortest time. To realize the "black box" record function, the SQLite3.0 embedded database is transplanted to real-time storage the Critical data. It is confirmed that the system operation is stable and reliable that can guarantee the monitoring and control system operation security and improving work efficiency, and it has a good application prospect.
