Research on Multi-channel Power Supply Method of New Intelligent Distributor

In view of the problems of the existing power supply module of downhole tools, such as narrow output voltage range and difficult to meet the complex power supply requirements, a new intelligent production distributor multi-channel power supply method was studied. The voltage conversion chip which can adapt to the underground working environment is selected as the core component of the power supply module, and a set of power supply scheme which can be multi-channel stable power supply is developed. By building the software and hardware experimental environment, the power supply stability, driving ability and communication compatibility of the scheme are tested. In the experiment, the voltage output of each branch of the power supply scheme is stable and the driving capacity is sufficient, which has no obvious influence on the communication quality of the intelligent generator. Experimental results show that the proposed scheme can supply power smoothly to the surface communication module, the underground intelligent production distributor and other tools as expected, and meet the power supply requirements of the intelligent production distributor.
