Description

  The present invention relates to an elevator maintenance work control system that performs control during elevator maintenance and inspection work.

  Conventionally, in an elevator control device, in order to automatically set and stop the car stop position at the time of maintenance and inspection work, the car stop position corresponding to the work content is stored in the storage unit of the terminal unit by the car position setting operation. In this state, first, the contents of the maintenance work are confirmed, the operation command is given, the operation command is transmitted to the main control device, and the car is controlled to be moved up and down. At this time, the CPU of the main control device controls the speed meter The position of the car is calculated based on the count value of the pulse signal by the controller, and the data is transmitted to the terminal. The control means of the terminal determines whether the calculated car position based on the count value of the pulse signal is stored in the storage unit. It is determined whether or not the position coincides with the stop position. If the positions coincide with each other, a stop command is transmitted to the main controller (see Patent Document 1).

Embodiment 1 FIG.
FIG. 1 is a diagram showing a schematic configuration of an elevator maintenance work control system according to the present invention, and FIG. 2 is a diagram showing a connection configuration of each part of FIG. In the figure, a main rope 2 is wound around a sheave driven by an elevator driving machine 1, and a car 3 and a counterweight 4 are coupled to both ends of the main rope 2. The encoder 5 generates a pulse output corresponding to the rotational speed of the driving machine 1, that is, the amount of movement of the car 3. A main control device 60 comprising a computer provided in the control panel 6 takes in the output of the encoder 5 and performs operation control of the car 3 including starting, stopping, accelerating, decelerating, etc. of the driving machine 1 in accordance with a built-in program.

  Then, as shown in the functional block, the main control device 60 performs car operation control means 60a for controlling the operation of the car based on normal call registration, and maintenance work control means 60b for controlling the entire work including the operation of the car during maintenance work. Display command control means 60c for causing the display means 7c of the maintenance terminal device 7 to be described later to display guidance for input to the input means 7b, etc., and the stop position data of the car according to the program and the content of the maintenance work Storage means 60d for storing maintenance operation data and the like.

  Similarly, the maintenance terminal device 7 composed of a computer is carried by a worker when performing maintenance work, for example, a car station 8a, a car station 8b, and a landing station 8c connected to a transmission network 8 serving as data transmission means. Is connected to the main control device 60 via the wireless communication mechanism 9 that also serves as a data transmission means, and is used for input / output of data, instructions, and commands during maintenance work, control processing, and display And so on according to the program with built-in.

  As shown in the functional block, the maintenance terminal device 7 is a maintenance / inspection work processing means 7a that performs processing for each maintenance work (data extraction, etc.) according to a program stored in the storage means 7d, such as a keyboard, a touch panel, and a mouse. Etc. (not shown), for example, a display means 7c comprising a liquid crystal display and its display control unit (not shown) is included. The display unit 7c performs guidance display for input to the input unit 7b based on image information stored in the storage unit 7d, for example, in accordance with a display command from the main control device 60.

  The main control device 60 is provided with a wireless communication mechanism 9 corresponding to wireless communication with the maintenance terminal device 7. Stations constituting the wired data transmission means such as the car station 8a, the car station 8b, and the landing station 8c connected to the transmission network 8 are not limited to those shown in FIG. It may be provided in the place or the main control device 60 (not shown), and can be used in the same building when transmitting data via the wireless communication mechanism 9.

  The elevator station 8b is connected to a lifting operation switch 11 that is operated by a worker on the cage to raise and lower the cage 3.

  FIG. 3 shows an operation flowchart for explaining an example of the operation of the elevator maintenance work control system according to the present invention. First, for example, an operator gets on the car 3 with the maintenance terminal device 7 and connects the maintenance terminal device 7 to the car station 8b. Then, when a maintenance work instruction is input by operating the input means 7b of the maintenance terminal device 7 (S1), a maintenance work program stored in the storage means 60d of the main control device 60 that receives this is received. First, the display unit 7c of the maintenance terminal device 7 displays guidance for input to the input unit 7b, and sequentially performs various maintenance operations according to the instruction input by the operator's operation to the input unit 7b. A screen is displayed (S2).

  In the maintenance work screen, a maintenance work selection screen for selecting the type of maintenance work is first displayed. When the maintenance work is selected, maintenance operation data of the maintenance work in the storage means 60d of the main control device 60 is then displayed. And a screen for selecting whether or not maintenance operation data needs to be newly created or updated.

  When there is a request to create or update maintenance operation data (S3), the next data setting method is "input setting" for inputting numerical values from the input means 7b, or setting the position while actually moving the car A selection screen for selecting "car position setting operation" is displayed (S4). If “input setting” is selected, an input screen for maintenance operation data, which is the stop position data of the car for the maintenance work, is displayed and a numerical value input is requested (S5). The stop position data input from the input means 7b according to this screen is stored as maintenance operation data of the maintenance work in the storage means 60d of the main controller 60 (S6). When “car position setting operation” is selected, “car position setting operation” to be described later is performed, and the car stop position data set in accordance with the car position setting operation is stored in the storage means 60d. (S7).

  Thereafter, a maintenance work execution confirmation screen is displayed on the display means 7c (S8). If an input for maintenance work execution is obtained, maintenance work described later is performed (S9).

  An example of the operation at the time of the car position setting operation in step S7 of FIG. 3 will be described according to the operation flowchart shown in FIG. First, a car stop position setting program stored in the storage means 60d of the main control device 60 is started based on an instruction for a car position setting operation by operating the input means 7b of the maintenance terminal device 7. Then, for example, when a lift instruction is issued by an operator operating the lift operation switch 11 connected to the car upper station 8b on the car 3, the main controller 60 receives this and the drive machine 1 is moved. The car 3 is driven and moved up and down according to the up / down instruction (S11).

  When the encoder 5 outputs a pulse corresponding to the amount of movement of the car 3 that accompanies the elevation, the main controller 60 counts the pulse and calculates the car position based on the counted value (S12). When the lifting / lowering instruction by the manual operation of the lifting / lowering operation switch 11 by the worker is interrupted (this is used as the car position instruction input) (S13), the count value at that time, that is, the stop position data is stored in the storage means 60d ( S14). Then, by repeating this setting pattern, the stop position data corresponding to the work content is stored in the storage means 60d of the main controller 60, and the car position setting operation ends (S15).

  An example of the operation during the actual maintenance operation after the above-described car position setting in step S9 in FIG. 3 will be described according to the operation flowchart shown in FIG. In this case, a car stop position corresponding to the work content is stored in the storage means 60d of the main controller 60 according to the car position setting operation described above. When a maintenance work execution instruction is input in step S8 in FIG. 3 (S21), the main control device 60 receives this, and the maintenance work operation program stored in the storage means 60d is activated to perform the maintenance work. Start. When an elevation instruction is input by operating the elevation operation switch 11, the drive machine 1 is driven and the car 3 is moved up and down (S22).

  At this time, main controller 60 counts the pulses output from encoder 5 (S23), calculates the car position based on the count value, and sets the calculated car position based on the count value in storage means 60d. It is determined whether or not it matches the stored car stop position (S24), and if it matches, a stop command is sent to the drive unit 1 (S25).

  Thus, by storing the car stop position data for maintenance work operation in the storage means 60d of the main controller 60, each worker can use the car stop position data for maintenance work operation in common. In addition, since it is not necessary to perform the car position setting operation for each worker, the overall efficiency of the maintenance work can be improved.

  In the above description, the raising / lowering instruction in step S12 of the car position setting operation in FIG. 4 and step S22 in the maintenance operation in FIG. 5 is performed by operating the raising / lowering operation switch 11. 7 may be performed by operating the input means 7b. In this case, the raising / lowering operation switch 11 becomes unnecessary. In this case, regarding the car position setting operation of FIG. 4, the operator may operate the car by connecting the maintenance terminal device 7 to another station without getting on the car 3.

  Further, as shown in FIG. 6, it is attached to the outside of the elevator car 3 so as to take a picture of a desired position outside the car, and is provided so as to be connectable to the maintenance terminal device 7 via the in-car station 8a. A video camera 12 may be provided. Then, the display means 7c of the maintenance terminal device 7 displays the above-described guidance screen and the video taken by the video camera 12 at the same time or by switching, for example, according to an operation input from the input means 7b. In this case, since it is not necessary for the worker to check the inspection point directly, it is not necessary for the worker to board the car 3 in both the car position setting operation and the maintenance work operation. For example, it is possible to connect the maintenance terminal device 7 to the in-car station 8a in the car 3 and perform the checking work while looking at the display means 7c.
