A detection system and detection method for the running state of an elevator

Abstract

The invention provides an elevator operating state detection system and method. The elevator operating state detection system comprises a three-axis acceleration sensor, an atmospheric pressure sensor, an acceleration computing module, a speed computing module, a height computing module and a judging module. The three-axis acceleration sensor is used for measuring operating acceleration of an elevator. The atmospheric pressure sensor is used for measuring the atmospheric pressure in the operating process of the elevator. The acceleration computing module is used for computing acceleration of the elevator in the operating direction based on data of the three-axis acceleration sensor. The speed computing module is used for computing the speed within a fixed time frame based on the acceleration obtained through the acceleration computing module. The height computing module is used for working out the current altitude based on the current atmospheric pressure measured by the atmospheric pressure sensor. The judging module is used for judging the operating state of the elevator according to the operating speed, the acceleration and the time of duration of the elevator. By the adoption of the elevator operating state detection system and method, the parameters are self-adaptive, and debugging is not needed for users; and the non-intrusive detection manner is independent of an elevator control system, operation of the elevator is not interfered, and safety is enhanced.

Description

technical field [0001] The invention relates to a detection system and a detection method for the running state of an elevator, belonging to the field of electrical technology. Background technique [0002] There are many kinds of equipment for state detection in elevators, such as acceleration testers and floor displays. These devices generally use acceleration sensors or photoelectric sensors, most of which are large in size, expensive and have restrictions on installation locations. The products tested often need to be installed on the top of the elevator car, and special elevator maintenance personnel are required to install them. These devices can generally only be used for elevator fault detection and are difficult to embed into other devices that require real-time elevator data. Modular and embeddable real-time detection devices require small size, easy installation, strong compatibility, high reliability and safety, and can effectively overcome various uncertain fac...
