Title: Xinxin Li: Innovator in Catalyst Measurement and Turnout Drive Systems

Introduction

Xinxin Li is a prominent inventor based in Shanghai, China, known for his contributions to the fields of catalyst measurement and turnout drive systems. With a total of seven patents to his name, he has made significant advancements that enhance the efficiency and reliability of various technologies.

Latest Patents

One of Xinxin Li's latest patents is a method for measuring the activation energy of a catalyst. This innovative method involves obtaining a resonant frequency change-time curve using an integrated self-heating resonant cantilever. The process includes converting this curve into a resonant frequency change-temperature curve, which is then transformed into a coverage-temperature curve. By performing first-order differentiation on the coverage-temperature curve, a coverage change rate-temperature curve is obtained. Relevant parameters corresponding to local minimum values are extracted from this curve, allowing for the calculation of a desorption rate constant and desorption activation energy of the catalyst. This method is notable for its simplicity, speed, and accuracy, requiring only programmed heating for sample operation, while also minimizing sample consumption and cost.

Another significant patent is the non-national standard turnout drive system based on a double 2-vote-2 architecture. This system includes an interlocking processing subsystem, an interlocking maintenance station, and a non-national standard turnout drive module. The design allows for high reliability and strong maintainability, as it utilizes mutually redundant turnout drive modules to control drive relays, ensuring precise operation and information collection regarding the turnout's position.
