When the elevator is running, the judgment of the upward or downward movement of the elevator is realized by the order of the state changes of multiple sensors. The size of the implementation process is large and the installation cost is high.
[0004] Especially corresponding to the after-installation third-party monitoring of the elevator Internet of Things transformation application, because this solution needs to install multiple sensors at the same position, the size and structure are relatively large, usually limited by the structure of the original sensor, the size is difficult to implement; if using In addition, the way of installing a magnetic isolation board will greatly increase the cost of system implementation.

Abstract
The invention discloses a composite type car all built-in elevator state sensor. The composite type car all built-in elevator state sensor adopts composite type multiple sensors to perform state comparison and judgment through an algorithm by utilizing acquired data of a magnetic/photoelectric sensor and an acceleration sensor, is high in reliability, and effectively reduces occurrence of mis-judgment and missed judgment of a conventional multi-magnetic/photoelectric sensor. Compared with a conventional flat-layer monitoring scheme, the composite type car all built-in elevator state sensor canmonitor information such as elevator acceleration, speed and displacement in real time, can timely respond when faults (over-speed, abnormal start-stop and stop at an un-flat layer) occur, and further can analyze and predicate related faults. According to the scheme, the composite type car all built-in elevator state sensor is small in dimension, is simple in structure, is safe, simple and convenient to implement, can be widely suitable for various elevators without modifying the structure of an existing flat-layer sensor. Compared with other multi-magnetic/multi-photoelectric monitoring schemes, the composite type car all built-in elevator state sensor is low in cost, is small in dimension, and also reduces the equipment cost and the mounting cost.
Description
technical field [0001] The invention relates to the technical field of elevator sensors, in particular to a composite car fully built-in elevator state sensor. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. [0003] As the main sensor, the leveling sensor is of great significance in the elevator monitoring scheme. At present, the existing elevator leveling sensor scheme mainly includes the following types: magnetic sensor based on magnetic isolation board / light isolation board, photoelectric sensor, based on reflection reflective photoelectric sensors for plates and magnetic sensors based on magnetic plates. The main feature of these solutions is that a specific partition or bracket needs to be installed on the guide rail at a ...
