Maintenance inspection system for elevator

A technology for inspection systems and elevators, which is applied to elevators, transportation, and packaging in buildings. It can solve the problems that sensors are difficult to detect, the height difference is not large, and the number of sensors is large, so as to prevent the cost from rising.

Problems solved by technology

[0004] As mentioned above, the on-site regular maintenance and inspection of the elevator is carried out at most 4 to 6 times a year. During the interval of the periodic inspection, if a major failure occurs, the elevator control device will stop the elevator system, so it will not develop into a problem. However, if a minor failure occurs, such minor failure may not be discovered until the next regular inspection, and if such a minor failure is ignored for a long period of time, there will be a risk to the brand Problems with adverse image effects
[0005] For this reason, as shown in Patent Document 1, for items that need to be inspected, sensors that detect physical changes are installed at each detection site, thereby avoiding the problem of brand image degradation caused by the lag of fault detection, but using this When designing a solution, it is necessary to install sensors at each detection position, and the number of sensors installed is large, which has the problem of cost increase
Not only that, for example, when the failure of the indicator light showing the floor where the elevator car is located is damaged, it is difficult to detect such failures even if the sensors are installed. When there is a large height difference between the car floors, the corresponding sensor will operate and detect the abnormality, but if the height difference between the two is not large, there is a problem that the sensor often does not operate

Embodiment Construction

[0051] Refer to the following Figure 1 to Figure 8 An embodiment example of the present invention will be described.

[0052] figure 1 is an overall configuration diagram of the present invention, showing an embodiment example, and refers to the following figure 1 This structure will be described.

[0053] The elevator car 1 carrying passengers and the counterweight 3 are connected to the main rope 2 through a sheave 4 and a deflection pulley 5. of electricity.

[0054] In addition, the motor 6 is equipped with a pulse generator 8, and the pulses generated as the motor rotates are input into the control device 9, and the control device 9 calculates the speed of the elevator car and the vertical position of the elevator car according to the pulses input. Various control data such as position in direction.

[0055] In the elevator car 1, in addition to being provided with known devices such as a display 10C for displaying the position of the elevator car, buttons 11C corre...

Abstract

The present invention provides a system, wherein running state of the elevator and opening / closing state of elevator door are combined and are set an operation mode, passengers are inquired about possibly generated fine fault and abnormity in the operation mode, simultaneously answer to the inquiry, the inquiry and the operation mode are related, then the information obtained by the relation is used in the maintenance inspection operation.

Description

technical field [0001] The present invention relates to an elevator maintenance inspection system, in particular to an elevator maintenance inspection system with an input function, the elevator passenger can use the function to judge the soundness and abnormality of the elevator, and can input the judgment result to the in the elevator system. Background technique [0002] For example, a scheme is disclosed in Patent Document 1. In this scheme, in addition to carrying out regular maintenance and inspection work several times a year on site by several maintenance personnel to ensure and maintain the performance of the elevator, it is also used as a maintenance inspection The device is equipped with sensors in various parts of the elevator system, and the operating data such as physical changes of the inspection parts are collected by these sensors and sent to the maintenance center, so that the maintenance and inspection work is carried out according to the operating data (r...
