The invention discloses a unit axis processing control system based on a WeChat public platform, and belongs to the technical field of water conservancy power generation equipment. The system is characterized in that a main control module is a 16-bit single-chip microcomputer, and is used for actively reading time data from a clock chip; runout data input remotely or input on a local keyboard andthe read time data are sent to a liquid crystal screen for display together through a wireless module by using an LCD driver; the runout data is sent to a chip to be stored through a serial interface;the runout data is transmitted to an upper computer server through a serial communication interface. The system has the advantages that the unit axis processing control system is combined with the WeChat public platform, the unit axis processing control system is put in a pocket, and multiple people can simultaneously use the system at different places only through WeChat numbers; the system is suitable for processing various types of hydro-power generating unit axes, historical data can be called rapidly and conveniently, the system performance is stable, the precision is high, time and labor are saved, and the overhauling period is shortened.
