[Prior art]
Elevator accidents are also related to the safety of passengers, etc., and regular maintenance inspections are performed by inspection workers so that normal operation is always maintained, and in order to check for malfunctions and prevent accidents. Work is carried out. Work such as checking the operation status of the elevator and confirming its operation by the workers is carried out at the installation location of the components of the elevator to be inspected, such as in the machine room, at the landing, or in the car, according to various inspection items. It was.
[0003]
FIG. 3 and FIG. 4 are block diagrams for explaining a conventional elevator operation inspection apparatus that is inspected by an operator. First, the car 1 and the counterweight 2 in the hoistway are connected via a hoisting machine 3. The main rope 4 is connected in a vine shape. The operation of the car 1 that moves up and down by the hoisting machine 3 is controlled by the elevator control panel 5.
[0004]
The elevator control panel 5 in the machine room is connected to the hall call registration unit 8 and the car 1 of each hall via a signal communication line 6 and a moving cable 7, as shown in detail in FIG. Operation control is performed in response to a call registration signal from the hall call registration button 8b via the hall interface 8a and a destination floor registration signal from a car operation panel (not shown).
[0005]
As shown in FIG. 4, the elevator control panel 5 includes a CPU unit 5 a that calculates and outputs an operation control signal based on an elevator operation command signal such as a call registration signal and a destination floor registration signal, and drives the hoisting machine 3. A data recording unit 5b for storing operation history data of a car that has been moved up and down by an operation control signal from the CPU unit 5a is provided, and the data recording unit 5b and the CPU unit 5a have first and second interfaces. 5c and 5d are connected.
[0006]
Therefore, in the configuration of FIGS. 3 and 4, the CPU unit 5 a 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 these operation control, that is, the above-described operation In addition to each registration signal, for example, the number of times the hall call registration button 8b is operated, the number of times the elevator is operated, and the like are calculated, and the calculation results are supplied to and stored in the data recording unit 5b.
[0007]
The first interface 5c is configured so that a hand-held control console 9 can be connected, and the operation history data stored in the data recording unit 5b is the first interface 5c. It is read out to the control console 9 side via 5c, and it can be confirmed whether there is any malfunction etc. from the data on the display.

Among the inspection items, there are relatively many failures such as landing errors such as landing slippage and opening / closing malfunction due to twisting of door guide shoes, etc., but some of these failures are in the signal transmission system for reading data. May be caused by a failure in the mechanical structure. In other words, for example, even if the elevator car has landed within the landing error, it may be recorded incorrectly in the data, and conversely, even if there is no abnormality in the operation history data, This is because the opening / closing operation is unnatural and the time required for opening / closing may be abnormally long.
[0011]
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 unit 5b, and determines the operation operation status of the elevator for each floor from the recorded data. Pass / fail check work and inspection work in the actual operation of the elevator were actually carried out for each floor.
[0012]
[Problems to be solved by the invention]
As described above, in the conventional elevator operation inspection device, even if the worker takes one inspection of the door opening and closing operation, the operator checks each floor by reciprocating between the elevator machine room and the corresponding floor each time. Because it was confirmed, the work required a lot of labor and a lot of time. Further, during the inspection work of the elevator, since it becomes difficult for passengers to use the elevator, the utilization efficiency is lowered, so that improvement has been demanded.
