DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device, and more particularly to an elevator control device suitable for controlling a car position for improving work efficiency during maintenance and inspection.

[0002]

2. Description of the Related Art Conventionally, as an elevator inspection apparatus for inspecting an operation management system during a normal automatic operation of an elevator, there is an elevator inspection apparatus disclosed in, for example, Japanese Patent Publication No. Sho 62-3077. This prior art discloses an inspection device for smooth operation when an elevator car is operated between predetermined floors, and a stop position of the car is made to stop only at a normal landing position. I was

[0003] However, in order to perform detailed work during maintenance and inspection, it is necessary to move the elevator car to a position other than the normal landing position to perform maintenance and inspection. It is necessary to move the car artificially by operating the / DOWN switch. In such manual operation at the time of maintenance and inspection, when the car is moved to and stopped at a position irrelevant to the landing position, the only option is to set the car position by relying on the rope marking and feeling.

[0004]

Therefore, in the conventional elevator control apparatus described above, the start and stop control are repeated in order to stop and move the car to a position irrelevant to the landing position during maintenance and inspection. There was a problem that the work efficiency was reduced. In addition, when working alone, there is no way to operate the car even when you want to move the car in the pit, etc., or when checking the car turning equipment from the landing, it may be difficult to set the car position. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems in the prior art, and an object of the present invention is to provide an elevator control apparatus capable of automatically setting a car stop position during a maintenance work and automatically stopping the car. Aim.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a main configuration diagram of an elevator control device. In FIG.
Reference numeral 2 denotes a main rope wound around a sheave of the driving machine 1, and a car 3 and a counterweight 4 are coupled to both hanging ends of the main rope 2.

Reference numeral 5 denotes a tachometer comprising a pulse generator for generating a pulse output corresponding to the number of rotations of the driving machine 1, that is, the amount of movement of the car 3, and 6 denotes starting, stopping and accelerating the driving machine 1.
A main control device which has a program for deceleration and operation of the car 3 and the like, and takes in the output of the tachometer 5 to control the driving machine 1. As shown in FIG. 2, an I / O port 6a and a RAM
6b, a computer 6e having a CPU 6c and a ROM 6d.

Reference numeral 7 denotes a terminal carried by the worker when performing maintenance and inspection. The terminal 7 is connected to the main control unit 6 via the connection means 8 or the wireless communication means 9 as data transmission means for data transmission. The terminal device 7 includes a storage unit that stores information on a car stop position according to the work content, and also includes car position information from the main control device 6 and information stored in the storage unit. And control means for controlling the operation by transmitting data of an elevator start command and a stop command to the main controller 6 based on the above.

The main controller 6 is provided with a wireless communication means 10 corresponding to wireless communication with the terminal device 7. Further, as shown in FIG.
It is provided inside or outside the car 3 or at any place in the hoistway or in the main control device 6 to enable data transmission between the portable terminal device 7 and the main control device 6, and to perform wireless communication. At the time of data transmission via the means, it can be used within the same building.

Next, the operation of the elevator control device configured as described above will be described with reference to the flowcharts shown in FIGS. FIG. 3 shows the flow of the work actually carried out on the car. First, the portable terminal 7 for maintenance work is connected to the main controller 6 via the connection means 8 (S31). After confirming the contents (S32), a work start command is issued to the main controller 6 (S33), and a car position setting operation according to the work contents is performed (S34). Then, after the set operation, the user gets on the car and performs maintenance work according to the set operation (S35).

FIG. 4 is a flowchart showing the flow of the specific car position setting operation in step S34. First, a car stop position setting program stored in the ROM 6d of the main control device 6 is started based on a car position setting operation command from the terminal device 7 (S41), and a lifting / lowering command is issued (S42). A pulse corresponding to the amount of movement of the car 3 as the car moves up and down is output from the tachometer 5, and the CPU 6c calculates the car position based on the count value (S4).
3).

When the manual ascending / descending command by the operator is stopped, the count value at that time, that is, the stop position is stored (S44, S45). Thereafter, the main controller 6
The car stop position is transmitted to the terminal 7 by data transmission and stored in the storage unit in the terminal 7 (S46). Then, the above-described setting pattern is repeated, and the stop position data corresponding to the work content is stored in the storage unit of the terminal device 7, and the car position setting operation ends (S47).

FIG. 5 is a flow chart showing the flow of the actual maintenance and inspection after the above-described car position setting. In this case, the storage unit of the terminal 7 stores the car stop position according to the work content by the above-described car position setting operation. First, the contents of the maintenance work are confirmed, and the operation command is given (S51, S52). The operation command is transmitted as data to the main control device 6, and the car 3 is controlled to move up and down.

At this time, the car position is calculated by the CPU 6c of the main control device 6 based on the count value of the pulse signal from the tachometer 5, and the data is transmitted to the terminal device 7 (S5).
3). The control means of the terminal device 7 determines whether or not the calculated car position based on the count value of the pulse signal matches the car stop position set and stored in the storage unit (S54). , A stop command is transmitted to the main controller 6 as data.

In this way, the car stop position can be set according to the work content during maintenance and inspection, and the car can be controlled to stop at the set car stop position based on the pulse count value proportional to the car movement amount. Work efficiency at the time of maintenance and inspection can be improved.
