The invention discloses an elevator equipment state monitoring system based on the large data technology. The system comprises a data collection unit, a communication system unit, a data diagnosis platform and a visual display unit. According to the system, a data collection device installed on a site collects elevator running state data, then the real-time data are pushed to an openPlant real-time database, the collected data are efficiently compressed and historically stored for a long time, and a client side application convenient and easy to use and a universal data interface are provided at the same time; by means of a high-speed two-way data transmission mechanism, on the one hand, multi-target elevator equipment real-time monitoring mass data are uploaded to a monitoring center; on the other hand, feedback and early warning for diagnosis results are achieved. By means of the data visual technology, transmission and communication interaction is effectively and clearly achieved, key information is more easily understood, more easily monitored effectively, and more visually transmitted, and therefore deep insight is achieved for a redundant and complex data set.
