And a data recording unit 5b for storing operation history data of the car that has been moved up and down by an operation control signal from the CPU unit 5a.
The data recording unit 5b and the CPU unit 5a have the first
And the second interfaces 5c and 5d are connected to each other.

Accordingly, in the configuration shown in FIGS. 3 and 4, the CPU unit 5a in the elevator control panel 5 generates an operation control signal based on the call registration signal and the destination floor registration signal, and the operation progress based on the operation control. That is, the number of times the hall call registration button 8b was operated, the number of times the elevator was operated, and the like were calculated in addition to the registration signals, and the calculation results were supplied to the data recording unit 5b and stored.

Further, the first interface 5c includes:
A hand-held type control console (console) 9 is configured to be connectable, and operation history data stored in the data storage unit 5b is read to the control console 9 via the first interface 5c. Issued

On the other hand, the second interface 5d includes:
A third interface 8a, which is a landing side interface of the landing call registration unit 8 of each floor, is connected via a signal communication line 6 which is a transmission line, and an operation command signal from the landing side is supplied.

In the inspection of the operation of the elevator by the inspection operator, on the one hand, it is checked whether or not the operation of the operation control system is normal from the recorded data, and on the other hand, the elevator itself actually operates properly. You need to check if you are going.

Among the inspection items, there are relatively many failures such as landing errors such as landing deviations and opening / closing operation failures caused by torsion of door guide shoes. Among these failures, there are signal readings for data reading. There may be a failure in the transmission system, or a failure in the mechanical structure. That is, for example, even if the elevator car has landed within the landing error, it may be incorrectly recorded on the data, and conversely, even if there is no abnormality on the operation history data, the elevator door This is because the opening / closing operation is unnatural and the time required for opening / closing may be abnormally long.

Accordingly, the operator first operates the control console 9 in the machine room, reads the operation progress of the elevator recorded in the data recording section 5b, and operates the elevator for each floor from the recorded data. The work of checking whether the operation status is good and the work of actually going to the floor of each stop floor and checking the actual operation of the elevator were performed for each floor.

[0012]

As described above, in the conventional elevator operation check device, even if the worker takes one check of the door opening / closing operation, the elevator machine room and the corresponding floor are provided for each floor. The work required a great deal of labor and a lot of time, because the inspection and check were made every time. In addition, during the inspection work of the elevator, it is difficult for passengers to use the elevator, so that the use efficiency is reduced, so that improvement has been demanded.
