Remote control toe end sliding sleeve opening system based on pressure pulse signal

The invention relates to a remote control toe end sliding sleeve opening system based on a pressure pulse signal. The remote control toe end sliding sleeve opening system comprises a pressure transmitter, a high-temperature and high-pressure electromagnetic valve, a microprocessor, NPN triodes and a high-temperature battery pack, the two NPN triodes are controlled through an STM32 single-chip microcomputer, a timer is arranged in the system, and the triggering time of the pressure transmitter and the high-temperature and high-pressure electromagnetic valve is stipulated. The fluid pressure detection time of the pressure transmitter is controlled in a timed mode through the NPN triodes, the high-temperature and high-pressure electromagnetic valve is opened after a ground pressure pulse signal is received, and opening of a sliding sleeve is achieved. The opening time of the toe end sliding sleeve is controlled, and meanwhile, the influence of the pressure in the pipe is avoided. The problems that an existing to
