DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator maintenance device provided for obtaining the total of the actual operation of an elevator.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Application Laid-Open No. Hei 3-152074, for example, in order to maintain and inspect an elevator, it is necessary to clarify the wear of a door device at a landing where a car is frequently landed, 2. Description of the Related Art An elevator maintenance device that plans each maintenance operation according to the landing frequency has been proposed.

[0003]

In the elevator maintenance apparatus described above, since the landing of the car is measured at each landing, it has not been possible to ascertain whether the car is going up or down. By the way, the wear of the door device and the parts related thereto is different between the stop when ascending and the stop when descending. Therefore, in the conventional maintenance work using the landing frequency of the car at each landing, there has been a problem that the maintenance work at each landing becomes inappropriate.

An object of the present invention is to solve the above-mentioned problems in the prior art, and an object of the present invention is to provide an elevator maintenance device capable of obtaining the frequency of landing of a car for ascending and descending, and performing appropriate maintenance work. Is to provide.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a position detecting means for detecting the position of a car ascending and descending a plurality of floors and landing on a designated floor. A traveling direction detecting means for detecting a traveling direction of the car, and a door opening detecting means for detecting that the door of each floor or the car door is opened. In the elevator maintenance device that records, based on the detection information of the position detection means, the traveling direction detection means and the door open detection means, the number of times the door has been opened for each floor rises, tabulated by descent It is characterized in that a total recording means for recording is provided.

[0006]

When the car is stopped and the car door or the floor door is opened, the elevator maintenance device adds and records the number of times the floor is stopped (the number of times the door is opened). The addition and recording are performed separately while the car is moving by inputting the traveling direction data of the car so as to distinguish between when the car is rising and when the car is descending.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a system configuration diagram of an elevator maintenance device according to an embodiment of the present invention. The elevator has a configuration in which a car 1 and a counterweight 2 are suspended in a sheave shape from a sheave 4 via a rope 3, and a brake 5, An electric motor 6 and a pulse generator 7 are mounted. The motor 6 is configured such that the rotation direction and the speed are controlled by the output of the power control device 11 that controls the power supplied from the main power supply 10.
Here, the power control device 11 is a microcomputer 1
The control signal from 2 controls the traveling direction of the car 1 and the brake 5. The power control device 11 is configured to be controlled by the output of the speed control device 13 to which the output of the microcomputer 12 is input.
The microcomputer 12 controls the operation of the elevator by the information obtained from the car position detecting device 20, the door opening detecting device 22 and the pulse generator 7 inputted through the tail cord connected to the car 1, and the car stops. In addition to the operation of controlling the door opening / closing device 21 for opening the door via the tail cord, various information can be output to the outside via the I / O port 15.

The above-described power control device 11, microcomputer 12, speed control device 13, and I / O port 15
Is connected to an elevator maintenance device 17 that records operating state data collected from each unit.

The elevator maintenance device 17 is composed of a microcomputer as shown in FIG. 2, and specifically, the MPU 1 which is a microprocessing unit.
71, a ROM 172 on which a program is mounted, a RAM 173 for recording operating state data of the car 1, an I / O port 170 connected to the I / O port 15 of the elevator control device 16, and signals from outside. Communication port 1 for input / output of
74, and a system bus 175 for transmitting addresses and control signals between these devices.

The elevator maintenance device 17 configured as described above.
Will be described with reference to a processing flowchart shown in FIG. It is assumed that the car travels from the first floor to the fourth floor and stops at the fourth floor. The elevator maintenance device 17 transmits information on the traveling direction of the car 1 from the elevator control device 16 to the microcomputer 12 and the I / O port.
The elevator maintenance device 17 determines that the traveling direction of the car 1 is the ascending direction based on this information (procedure S1), and then stops the car 1. Then, it keeps checking that the door is opened (procedure S2). When the car 1 stops on the fourth floor, the elevator control device 16 operates the door opening / closing device 2.
1 is instructed to open the door. With this command, the door opening / closing device 21 starts to open the door. At this time, the door opening detection device 22 detects that the door has been opened. The information detected by the door opening detection device 22 is transmitted to the microcomputer 1
2, read out to the elevator maintenance device 17 via the I / O port 15 and the I / O port 170. As a result, the elevator maintenance device 17 confirms that the elevator has stopped and the door has been opened. Next, the elevator maintenance device 17 includes an I / O port 170,
Information on the floor at which the car 1 is stopped is read via the I / O port 15 and the microcomputer 12 (step S3). Based on the information read in step S3, the elevator maintenance device 17 adds “1” to the numerical value of the RAM 173 that stores the ascent / stop total value of the corresponding floor (step S4).

Next, when the car 1 travels from the fourth floor to the first floor and stops at the first floor, the elevator maintenance device 17 determines that the car 1 is in the descending direction based on the traveling direction information from the elevator control device 16. (Procedure S1) Then, it continues to confirm that the elevator stops and the door opens (procedure S5). When the car 1 travels and stops on the first floor, the elevator control device 16 commands the door opening / closing device 21 to open the door. With this command, the door opening / closing device 21 starts to open the door. At this time, the door opening detection device 22 detects that the door has been opened. The information detected by the door opening detection device 22 is transmitted to the microcomputer 1
2, read out to the elevator maintenance device 17 via the I / O port 15 and the I / O port 170. As a result, the elevator maintenance device 17 confirms that the elevator has stopped and the door has been opened. Next, the elevator maintenance device 17 includes an I / O port 170,
The information on the floor at which the elevator is stopped is read out via the I / O port 15 and the microcomputer 12 (step S6). Based on the information read in step S3, the elevator maintenance device 17 adds “1” to the numerical value of the RAM 173 that stores the descending stop total value of the corresponding floor (step S7).

Thus, in the present embodiment,
Since the landing frequency of the car can be obtained for each descent, the maintenance work for each of the landings for the ascent and descent can be appropriately performed.

[0013]

As described above, according to the present invention,
Since the landing frequency of the basket is obtained separately for ascending and descending,
The maintenance work can be appropriately performed for each of the landings by ascending and descending, and a maintenance work plan according to the frequency of landing of the car can be made for ascending and descending.
