A new monitoring method using distributed optical temperature measurement to measure the temperature of reactor is put forward in the paper. The paper describes the characteristics of the system, and also provides an arrangement scheme of fiber to en-sure the system running well. Good man-machine interface of the system will help staff to check the temperature easily, and send warning signal.
In order to achieve online monitoring the downhole information related to ESP working state, an ESP downhole parameters monitoring system based on current loop data transmission method was developed. Compared with other methods, the current loop data transmission method was relatively insensitive to interference in harsh environment. By means of ESP motor's winding and symmetrical reactance located...
In consideration of the complex condition of down hole environment, an ESP down hole multi-parameter comprehensive measurement system was designed in this paper in order to monitor the down hole information. Firstly, structures of the up hole section and down hole section of the system were introduced respectively. Then some key technologies on the system were illustrated in detail which consists...
This paper presents a new substation auxiliary control system communication scheme based on WIA industrial wireless technology. The structure and operation principle are introduced, and the technical difficulties and solutions of the WIA industrial wireless technology in substation auxiliary control system application are analyzed from the network protocol and hardware design. The validity of the...
The high-voltage transformer substation is a special environment with high voltage and strong magnetic field. The temperatures of transmission circuitry joints in substations may increase for many reasons to initiate fire and explosion. A hierarchical clustering wireless sensor network (WSN) based on multi-agent system (MAS) is provided in this paper. Sustainable power-supplied nodes are appointed...
