[Detailed description of the invention] [Industrial application field] The present invention relates to an inspection device for an elevator.

[Conventional Technique 1] In the past, inspections of elevators and escalators have been carried out by maintenance personnel who regularly visit the elevators to check the operational status of each part of the elevator visually or using a measuring device.

However, with this conventional inspection method, the diagnosis of the operating status of each part of the elevator may differ depending on the maintenance staff's judgment based on their measurement skills and experience, and there is a drawback that individual differences appear in the inspection results. .

For this reason, parts replacement and maintenance work performed based on the above-mentioned inspection results may be carried out in vain even though they are not necessary.
On the other hand, if the product is left unattended without parts replacement or maintenance work,
Occasionally, elevators malfunctioned.

Therefore, an elevator inspection system has been proposed in Japanese Patent Laid-Open No. 60-244782, which efficiently performs inspections with high diagnostic accuracy commensurate with the environment in which the elevator is used, its operating history, and the characteristics of the equipment.

The elevator 1 includes various sensors 3 such as a vibration sensor and a magnetic brake operation sensor, and a control device 2 that controls the operation and inspection of the elevator 1. provided, this sensor 3
A microcomputer 4 having an automatic inspection function is connected to the controller 2 and the controller 2.

A mobile terminal 5 is connected to this microcomputer 4,
This mobile terminal 5 is connected to a host computer 7 via a communication transmission line 6 and a direct transmission line 9.

In the method according to the above-mentioned proposal with such a configuration, the detection information from the sensor 3 is sent to the microcomputer 4 at regular intervals.
is stored in the RAM.

Then, the detection information stored in the RAM of the microcomputer 4 is compared with each inspection limit value of the elevator 1, and if the comparison value exceeds the allowable range, it is written to the abnormality detection RAM of the microcomputer 4.

The aforementioned mobile terminal 5 is provided with a keyboard, and by selectively operating the operation switch of this keyboard, the first
It is possible to select and import information held by the microcomputer 4 and write it into the RAM of the mobile terminal 5.

By operating the keyboard of the mobile terminal 5, the abnormality detection frequency history, measured driving data, test driving data, etc. are selectively sent to the mobile terminal 5 from the first microcomputer 4.
and output to the display device or printing device of the mobile terminal 5 as necessary.

In this way, according to the method proposed above, inspection data that has been narrowed down to key points based on the maintenance staff's judgment and data that has extracted abnormalities before they become defective are written to the RAM of the mobile terminal 5 and sent to the monitoring center. Take home host computer 7
This allows time-series changes to be analyzed for each elevator.

Based on the results of this analysis, it is possible to efficiently determine when to replace parts or make adjustments for each elevator with high diagnostic accuracy.

[Problem that the invention seeks to solve]

In the method according to the above-mentioned proposal, the inspection data and extracted data selected by the maintenance personnel are imported into the mobile terminal 5;
Assuming extreme conditions, the RAM of the mobile terminal 5 needs to have a capacity in which all the inspection/extraction data detected by the sensor 3 can be written.

As described above, it is necessary to increase the capacity of the RAM, and the entire mobile terminal 5 including other control circuit parts becomes large as a mobile device, making it inconvenient to handle.

Furthermore, since the storage capacity of the mobile terminal 5 is limited, it is not possible to store all the maintenance procedures for malfunctions in the operation of the elevator, and it is not possible to store all the maintenance procedures for malfunctions in the operation of the elevator. However, appropriate measures may not be taken at the scene.

Furthermore, if you try to perform inspection work using the latest inspection/adjustment data, you will have to update the terminal data for all of the numerous mobile terminals 5 each time, which is time-consuming and difficult. be.

The present invention has been made in view of the current state of inspection work for elevators and escalators as described above, and its purpose is to allow signals to be sent and received between a mobile terminal and a host computer, to miniaturize the mobile terminal, and to improve the efficiency of elevator inspection work.
