The invention discloses an intelligent monitoring system for elevator safe operation based on IOT (Internet of Things) technology. The intelligent monitoring system is mainly designed for government regulation departments, maintenance units, manufacturers, property management companies and the like, and provides the above with a set of intelligent, platform-based total management system which supports wireless access and remote access, so that safe operation, management, maintenance and detection of an elevator can be more effectively realized. While daily needs are met, monitoring on the elevator is more normalized, institutionalized and scientized, so that elevator accidents are further reduced, and speed and quality for solving problems after an accident occurs are improved; by utilizing information for driving, the informatization management level of the intelligent monitoring system is improved through advanced and applicable technology and exploitation and construction pattern innovation by comprehensively utilizing information science and technology as well as decision making and management methods, and an emergency response system of elevator safety is favorably established.
