Method and device for detecting loading conditions of elevator car

Abstract

The invention discloses a method for detecting loading conditions of an elevator car. The method comprises the following steps of: dividing a bottom plate of the elevator car into N regions (N is larger than 1); enabling a pressure sensor used for detecting the load of each region to be arranged at each region; receiving the load of each region of the bottom plate of the elevator car, which is detected by the corresponding pressure sensor; summing up the received loads of N regions to obtain a total load value; and judging whether the elevator car is in an abnormal loading status according to the obtained total load value and the received distribution condition of the loads of the N regions. Accordingly, the invention further discloses a device for detecting loading conditions of the elevator car. Through the adoption of the method disclosed by the embodiment of the invention, the loading conditions of the regions of the bottom plate of the elevator car can be detected by the pressure sensors distributed on the bottom plate of the elevator car, so that the accuracy for judging the loading conditions of the elevator car is improved, and the service efficiency of an elevator is further improved.

Description

technical field [0001] The invention relates to the technical field of elevator equipment load, in particular to a method for detecting the load of an elevator car. Background technique [0002] In existing passenger elevators or freight elevators, a pressure sensor is generally placed at the center of the car floor to convert the degree of deformation at the center of the floor into a voltage signal to determine the current load situation. [0003] However, the existing solutions have the following defects: when the passenger positions are not uniform, the degree of deformation in different areas of the car floor is also inconsistent, and the degree of deformation at the center of the floor depends on the load distribution in the car. Therefore, when the deformation degree at the center of the bottom plate is higher than the average deformation degree of the car, even if the current load has not reached the upper limit of the elevator, the elevator may still sound an alarm....

After the elevator misreported, some passengers had to leave the car, which not only reduced the efficiency of the elevator, but also delayed the valuable time of the passengers
