Detailed Description
Embodiments related to an elevator, an elevator control method, and an elevator control program according to the present invention will be described in detail below with reference to the accompanying drawings.
Elevator
Fig. 1 is an overall configuration diagram of an elevator 1 according to an embodiment of the present invention. As shown in fig. 1, an elevator 1 has a car 11, a counterweight 12, and a main hoist rope 13 connecting them at both ends in a travel passage 10 extending in a predetermined direction along a building (building). A machine room 10a is disposed above the travel path 10, and a hoist 14 for winding a main rope 13 is provided in the machine room 10a.
A hall door 16 is provided on the wall surface of the travel passage 10 so as to face a hall 15 provided at each of floors F1, F2, and 8230a of a building. When the car 11 reaches each hall F, each hall door 16 engages with the car door 11a, and by opening the car door 11a, the hall door 16 and the car door 11a are opened together.
Each hall 15 is provided with a call operation unit 20 and a hall control unit 21. Among these, the call operation unit 20 has at least an up call button 20a and a down call button 20b.
That is, the call operation unit 20 provided in the entrance hall 15 of the lowermost floor F1 has an up call button 20a. The call operation unit 20 provided in the entrance hall 15 of the intermediate layer F2, \8230 \ has an up call button 20a and a down call button 20b. The call operation unit 20 provided in the entrance hall 15 of the uppermost Fn includes a call down button 20b. These up call button 20a and down call button 20b are hall call buttons provided as operation terminals on the call operation unit 20.
The hall control unit 21 is connected to the call operation unit 20, and transmits operation signals of the up call button 20a and the down call button 20b of the call operation unit 20 to the control device 30 described below. Each hall control unit 21 typically includes the same number of connection ports 22a and 22b. The connection ports 22a and 22b are individually connected to the up call button 20a and the down call button 20b of the call operation unit 20. Therefore, each hall control unit 21 has at least 2 connection ports 22a and 22b. Such hall control unit 21 is connected to a control device 30 described below via a wiring 23.
In the above configuration, hall controller 21 provided in intermediate layer F2, \8230amis in a state in which call button 20a and call button 20b are connected individually to 2 connection ports 22a and 22b. The hall controller 21 provided at the uppermost layer Fn is connected to the down call button 20b only at one connection port 22b of the 2 connection ports 22a and 22b, and the other connection port 22a is a spare port 22x. In contrast, the hall control unit 21 provided in the lowermost layer F1 connects the call button 20a to only one connection port 22a among the 2 connection ports 22a and 22b, and the other connection port 22b becomes the spare port 22y.
Any one of these spare ports 22x and 22y serves as a restoration operation input unit, and is distinguished from the other connection ports 22a and 22b as a predetermined connection port 101 to which the connector 100 is detachably connected. In addition, the connector 100 is used for the maintenance person of the elevator 1 to transmit a signal for permitting the recovery to the normal operation mode to the control device 30. Such a connector 100 transmits an on signal in a state of being connected to a predetermined connection port 101, for example, and stops transmission of the on signal in a state of being pulled out from the predetermined connection port 101. In addition, the reverse is also possible.
Here, in the inspection work of the elevator 1, the maintenance worker performs the work by entering the pit 10b at the lower part of the travel path 10, and after the work is completed, the worker who has exited the pit 10b performs the work of the connector 100. Thus, the connector 100 can connect with any of the spare ports 22y, 22x. However, in consideration of convenience of operation of the connector 100, it is preferable to connect the connector 100 by using the free port 22y of the hall control unit 21 in the lowermost layer F1 closer to the pit 10b as a predetermined connection port 101 serving as a return operation input unit, as shown in the drawing.
Typically, control device 30 is disposed in machine room 10a at a position close to hoisting machine 14. The control device 30 controls opening and closing of the car door 11a provided in the car 11 and driving of the hoisting machine 14.
Here, the control device 30 is constituted by a computer. A computer is hardware used as a so-called "computer". The computer includes a nonvolatile storage Unit such as a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and an HDD (hard disk drive), and may further include a network interface.
The control device 30 configured by such a computer stores a control program related to the operation of the elevator including the driving of the car door 11a and the hoisting machine 14 in a nonvolatile storage unit, and executes processing based on the stored control program to control the operation of the elevator 1. The control device 30 includes a drive control unit 30a and a recovery permission determination unit 30b as functional units for executing a control program.
The drive control unit 30a controls opening and closing of the car door 1a and traveling of the hoisting machine 14 based on signals from a car call operation unit (not shown) provided in the car 11 and signals from the call operation units 20, and further based on signals from various sensors not shown here. Further, the restoration permission determination unit 30b permits restoration from the inspection mode to the normal operation mode when the operation mode of the elevator 1 is the inspection mode based on the signal from the predetermined connection port 101. Details of permission of restoration by the restoration permission determination unit 30b will be described in the following elevator control method.
Elevator control method
Fig. 2 is a flowchart illustrating an elevator control method according to the embodiment. The elevator control method shown in this figure is a control procedure implemented by using the control program held in the control device 30 described with reference to fig. 1, and is a procedure of processing for ending the inspection of the elevator 1 and returning it to the normal operation mode. The elevator control method is described below with reference to fig. 1 according to the flow chart of fig. 2.
< step S101>
In step S101, the restoration permission determination unit 30b determines whether or not a signal from a predetermined connection port 101 is received. Here, the predetermined connection port 101 is the free port 22y to which the connector 100 is connected, and is a port serving as a restoration operation input unit among the connection ports 22a and 22b. When determining that the signal from the predetermined connection port 101 is received (yes), the restoration permission determination unit 30b proceeds to the next step S102, and otherwise, repeats the determination.
< step S102>
In step S102, the restoration permission determination unit 30b determines whether or not a restoration permission signal is received from a predetermined connection port 101. Here, the resume permission signal is a rectangular wave signal that is turned off by the connector 100 connected to the predetermined connection port 101 being pulled out from the predetermined connection port 101, and then turned on again by being connected to the predetermined connection port 101. That is, the restoration permission determination unit 30b determines whether or not the worker has left the pit 10b based on the rectangular signal, pulls out the connector 100 from the predetermined connection port 101 of the hall control unit 21, and then connects the pulled-out connector 100 to the predetermined connection port 101 again. When determining that the signal is the resume permission signal (yes), the resume permission determination unit 30b proceeds to the next step S103. If it is determined that the signal is not a resume permit signal (no), the process returns to step S101.
< step S103>
In step S103, the recovery permission determination unit 30b permits the drive control unit 30a to resume the operation mode from the inspection mode to the normal operation mode. In this way, the drive control unit 30a returns the operation mode from the inspection mode to the normal operation mode, and ends the processing.
Effect of the embodiment
According to the embodiment described above, the maintenance work of the elevator 1 can be ended and the normal operation mode can be returned to by using any one of the free ports 22x and 22y among the connection ports 22a and 22b of the plurality of hall control units 21 as the return operation input unit. As a result, as shown in fig. 1, the dragging wire 200 between the control device 30 and the restoration operation input unit 101' for transmitting the restoration permission signal can be eliminated, and the number of wires in the elevator 1 can be reduced. As a result, the number of wires can be reduced without adding any equipment to the elevator 1.
In the above-described embodiment, the determination of the input of the resume enable signal is configured to determine whether or not the following process is performed: the connector 100 connected to the predetermined connection port 101 is pulled out, and then the pulled-out connector 100 is connected to the predetermined connection port 101 again. This prevents the connector 100 from being lost or forgotten to be brought back. However, if the loss of the connector 100 or the forgetting to return the connector can be disregarded, the determination may be configured as follows: it is determined whether the connector 100 is connected to a given connection port 101 and then the connected connector 100 is pulled out from the given connection port 101. Further, if the problem of the operation error can be eliminated, an input switch for restoring the permission may be connected to a predetermined connection port 101.
As described above, the present invention is not limited to the above-described embodiments and modifications, and various modifications are further included. For example, the above-described embodiments have been described in detail to explain the present invention in an easily understandable manner, but the present invention is not necessarily limited to the embodiments having all the configurations described. Further, a part of the structure of one embodiment may be replaced with the structure of another embodiment, and the structure of one embodiment may be added to the structure of another embodiment. Further, addition, deletion, and replacement of another configuration can be performed on a part of the configurations of the respective embodiments.
