Embodiment 1
[0047] refer to figure 1 , a method for judging elevator operation and maintenance, comprising the following steps in sequence:
[0048] Step 1: After the elevator is put into operation, record the air pressure value of the lowest floor and obtain the total number of floors and the height of the building where the elevator is located;
[0049] Generally speaking, after the elevator is put into operation, it will start to run from the lowest floor. At this time, the air pressure value will be recorded, and after each leveling floor, the floor of the leveling floor will be calculated and the air pressure corresponding to the floor will be recorded as the corresponding air pressure of the floor. Standard air pressure, continue this operation, every time it reaches the next leveling floor, calculate the number of floors on this floor and update the standard air pressure.
[0050] Can refer to figure 2 , figure 2 is the air pressure change value at the same location within a d...
Embodiment 2
[0082] refer to Figure 5 , a maintenance system for an elevator, comprising a server 1 and an elevator, the elevator is provided with an air pressure sensor 3, a controller 4, and a communication module 2, and the communication module is used to communicate with the server;
[0083] Described controller 4 comprises following modules:
[0084] Storage sub-module 41: used to store the total number of floors of the building where the elevator is located, the height of the building, the air pressure value, the set of air pressure values, and the time corresponding to the air pressure value;
[0085] Running state calculation sub-module 42: used to judge the running state of the elevator according to the air pressure value in the running process of the elevator. The running state includes the upward state, downward state, and leveling state of the elevator; The air pressure value to the next leveling state is used to obtain the air pressure value set; it is also used to draw the ...

Abstract
The invention belongs to the technical field of Internet of Things, and discloses an elevator operation and maintenance judgment method which sequentially comprises the following steps that 1, after an elevator is put into operation, the air pressure value of the lowest floor is recorded, and the total floor number and the floor height of a building where the elevator is located are obtained; 2, the air pressure value of the elevator in the running process is obtained; 3, calculating the passing floor height and the floor in the next leveling state, and calculating the time from the previous leveling state to the next leveling state; 4, judging a fault point and sending the fault point to an external server; according to the method, the accuracy of fault judgment in the elevator running process can be improved through the air pressure sensor. Meanwhile, the invention further discloses an elevator maintenance system.
Description
technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an elevator operation and maintenance judgment method and an elevator maintenance system. Background technique [0002] CN201811063271.6 discloses an elevator running detection method and device based on relative air pressure and height error correction; calculate the real-time height of the car through the relative air pressure between the real-time elevator position and the last elevator leveling position, and calculate the air pressure data within a predetermined time Change to judge the leveling state of the car, judge whether there is a leveling fault in the car by comparing the real-time height with the standard height, use the standard height as a reference value to correct the error existing in the calculation and judgment of the real-time height of the car, and use the real-time height The current floor number is calculated by comparing with the standard h...
