| Abstract: |
| Objective To design a remote monitoring system of pulsed current cathodic protection for oil well casings,in order to ensure the operation safe and achieve intensive, digital management with cathodic protection. Methods Based on the secondary inversion and GPRS technology, the microcomputer of C8051F020 was used as the control core for the pulse power supply system and the GPRS module of HAR306 for wireless data transmission,combining with remote monitoring center, real-time monitoring for oil well casing pulsed current cathodic protection was realized. Results The system had advantages such as low cost,powerful network building,friendly interface,powerful function and reliable data transmission,which could realize the digital, intensive and intelligent management for pulse current cathodic protection. Conclusion The main circuit of pulsed current power for well casing cathodic protection was designed using the second inverter method,on this basis,the scheme of designing wireless remote monitoring system using the GPRS technology was feasible. |
