Song Hai-zhi · China Measurement & Test · 2010
In order to solve problems of injection test modification in oil field,a new remote test technology project based on PLC was designed,which uses LonWorks field bus and power line transceiver PLT-22 to deal with communication affairs,and made use of the neuron chip to achieve communication control and injection test modification.As communication between above-ground equipment and sub-well instrument was realized by PLC,the problem of power of sub-well instrument has been solved.Especially,the key problems of real-time and stability in the existing equipments can be solved.Hereby accuracy and working efficiency of systems can be further enhanced.
