Design of Auto cylinder pressure measurement system based on PCB planar Rogowski coil

A new method for reflecting the Auto cylinder pressure via measurement of ignition current is presented in this paper. It expounds in detail the design thought of system design, transmitter design, implementation of host computer of the system and design of the system software, presents a solution for testing cylinder pressure based on the transmission mode of PCB planar Rogowski coil as transmitter and wireless network, makes improvement to signal conditioning circuit for higher reliability of program and lower R&D cost by the design thought of modular software, which is valuable for guidance and reference in the research and development of similar testing system.
