FIG. 5 is a flowchart illustrating information processing in the passenger conveyor control device according to the embodiment.

  Hereinafter, the control device (henceforth, control device 40) of a passenger conveyor concerning an embodiment is explained in detail with reference to drawings. In addition, the following embodiment is an illustration and the range of invention is not limited to them. In addition, constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art or those that are substantially the same.

  In the present embodiment, the escalator 1 will be described as an example of a passenger conveyor that operates by rotating (circulating) a plurality of steps connected endlessly.

  As shown in FIG. 1, the escalator 1 is connected endlessly between a drive wheel 3 and a driven wheel 4 disposed inside a truss (structure frame) 2 and between the drive wheel 3 and the driven wheel 4. And a plurality of steps (steps) 5. The drive wheel 3 is disposed on the upper floor side, and the driven wheel 4 is disposed on the lower floor side. In FIG. 1, three steps 5 are shown. A drive chain 7 is provided between the drive wheel 3 and the speed reducer 6. The speed reducer 6 is provided with a motor 8. A step chain 9 is stretched between the drive wheel 3 and the driven wheel 4. The step chain 9 is connected to a plurality of steps 5 on which passengers (not shown) ride. By driving the motor 8, the step chain 9 is driven, and the plurality of steps 5 move between the driving wheel 3 and the driven wheel 4. When the rotation direction of the motor 8 is switched between forward rotation and reverse rotation, the driving direction of the step chain 9 is switched, and the ascending operation and the descending operation of the step 5 are switched.

  When the escalator 1 operates in the descending direction (the direction indicated by the solid arrow in FIG. 1), the plurality of steps 5 are located in the upper floor side entrance 10 so that the adjacent steps 5 are horizontal in the traveling direction and from within the truss 2. Advancing, expanding the step between adjacent steps 5 in the upper transition curve, transitioning to a staircase shape, descending in a stepped manner in the middle slope, reducing the step between adjacent steps 5 in the lower transition curve After that, the vehicle is transitioned to a horizontal state, becomes horizontal again at the lower floor entrance 11 and enters the truss 2. The plurality of steps 5 that have entered the truss 2 are inverted upward, raised on the return side in a horizontal state, inverted again, and advanced from the truss 2 at the upper floor entrance 10. When the escalator 1 operates in the ascending direction (the direction opposite to the solid line arrow direction in FIG. 1), the above operation is reversed. A boarding board (not shown) is provided at the upper floor entrance 10 and the lower floor entrance 11. A comb-shaped comb (not shown) is provided on the boarding board. The escalator 1 includes a pair of balustrades 20 on both sides in the traveling direction of the plurality of steps 5.

  In the escalator 1 configured as described above, as shown in FIG. 1, a drive mechanism (not shown) circulates the step chain 9 around the drive wheel 3 and the driven wheel 4 so that the step 5 is connected to the lower floor and the upper floor. The passenger on the step 5 is transported across the lower floor and the upper floor.

  The operation panel has a switch for starting up the escalator 1 and starting the down operation, and a plurality of switches are arranged. Here, the operation panels are the upper floor operation panel 20 disposed on the skirt guard of the upper floor side entrance 10 and the lower floor operation panel disposed on the skirt guard of the lower floor entrance 11. There are 30.

  As shown in FIG. 2, the upper floor side operation panel 20 mainly includes an operation panel control unit 21 and an operation start switch (operation start SW) 22. The upper floor side operation panel 20 is connected to a control device 40 (described later) via the operation panel control unit 21 so as to be able to exchange control signals. As shown in FIG. 3, the operation start SW 22 inserts the operation key into the key hole and rotates the operation key to the “UP” position to start the escalator 1 when the escalator 1 is started to move upward. In this case, the operation key is rotated to the “DN” position. The upper floor operation panel 20 transmits a control signal for starting up and starting down the escalator 1 to the control device 40 based on the position of the operation key (“UP” position, “DN” position). Thereby, when the position of the operation key is set to the “UP” position, the escalator 1 starts the ascending operation by the control device 40. Further, when the position of the operation key is set to the “DN” position, the escalator 1 starts the descending operation by the control device 40.

  The lower floor side operation panel 30 is configured in the same manner as the upper floor side operation panel 20. In this manner, the upper floor side operation panel 20 and the lower floor side operation panel 30 can similarly control the start of the escalator 1 to start up and start to descend. Further, the upper floor side operation panel 20 and the lower floor side operation panel 30 can select an operation panel that permits operation control of the escalator 1 based on the operation by an operation panel selection SW 44 of the control panel 41 described later.

  The operation of the escalator 1 is realized by controlling the speed reducer 6 and the motor 8 based on the operation control circuit by the control device 40. The control device 40 is a computer having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The function of the control device 40 is to load application programs held in the ROM into the RAM and execute them by the CPU, thereby operating various devices in the escalator 1 under the control of the CPU, and data in the RAM and ROM. This is realized by reading and writing.

  The control device 40 is disposed in the upper floor side machine room (see FIG. 1), and as shown in FIG. 2, a control panel 41 disposed mainly on the upper side of the control device 40, and the control panel 41 And a control unit 45 for controlling the above.

  The control panel 41 is provided with a plurality of switches on which an operator performs operations related to the escalator 1. Specifically, the control panel 41 is provided with a safety switch (safety SW) 42, an inspection switch (inspection SW) 43, and an operation panel selection switch (operation panel selection SW) 44.

  The safety SW 42 is a switch for switching on / off of a safety circuit 46 described later. Specifically, as shown in FIG. 4, the safety SW 42 moves the switch lever to the “ON” position when the safety circuit 46 is turned on, and moves the switch lever to the “OFF” position when the safety circuit 46 is cut. To move. At the time of inspection work, the operator moves the switch lever of the safety SW 42 to the “ON” position and turns on the safety circuit 46. The safety SW 42 transmits a control signal for turning on / off the safety circuit 46 to the control unit 45 based on the position of the switch lever (“ON” position, “OFF” position). Thereby, when the switch lever is in the “ON” position, the safety circuit 46 is turned on, and when the switch lever is in the “OFF” position, the safety circuit 46 is cut off.

  The inspection SW 43 is a switch that switches between normal operation and inspection operation of the escalator 1. Here, the normal operation means that the operation key is inserted into the key holes of the upper floor side operation panel 20 and the lower floor side operation panel 30 and the operation key is rotated to the “UP” position and the “DN” position, and then the key hole. It is the control by the operation control circuit that continues the ascending operation and the descending operation of the escalator 1 in a state where the operation key is removed from. The operation at the time of inspection is set at the time of inspection work or the like, and the operation key is entered from the key holes of the upper floor side operation panel 20 and the lower floor side operation panel 30 selected by the operation panel selection SW 44 described later. In the removed state, it is the control by the operation control circuit that stops the escalator 1. That is, in the inspection operation, the escalator 1 performs the ascending operation and the descending operation with the operation key inserted into the key hole, and the escalator 1 stops when the operation key is removed from the key hole. Become.

  Specifically, as shown in FIG. 4, the inspection SW 43 moves the switch lever to the “inspection” position when performing the inspection operation, and moves the switch lever to the “normal” position when performing the normal operation. This inspection SW 43 is a control signal indicating whether the escalator 1 is to be an operation control circuit for normal operation or an operation control circuit for operation during inspection based on the position of the switch lever (“normal” position, “inspection” position). Is transmitted to the control unit 45. Thereby, when the position of the switch lever is the “normal” position, an operation control circuit in which the escalator 1 is normally operated is obtained. When the switch lever is in the “inspection” position, the escalator 1 is an operation control circuit that is operated during inspection.

  The operation panel selection SW 44 is a switch that selects an operation panel that permits operation control of the escalator 1 based on an operation among a plurality of operation panels (upper floor operation panel 20 and lower floor operation panel 30). Specifically, as shown in FIG. 4, the operation panel selection SW 44 moves the switch lever to the “up” position when the operation control of the escalator 1 based on the operation of the upper floor operation panel 20 is permitted, When the operation control of the escalator 1 based on the operation of the floor side operation panel 30 is permitted, the switch lever is moved to the “down” position. Further, the operation panel selection SW 44 moves the switch lever to the “normal” position when both the operation control of the escalator 1 based on the operation of the upper floor operation panel 20 and the lower floor operation panel 30 are permitted. This operation panel selection SW 44 is based on the control signals from the upper floor operation panel 20 and the lower floor operation panel 30 based on the position of the switch lever (“up” position, “down” position, “normal” position). A control signal for switching whether to permit the operation control of the escalator 1 based on the operation (whether to enable the control signal) is transmitted to the control unit 45.

  Thereby, when the position of the switch lever is the “up” position, the operation control of the escalator 1 based on the operation of the upper floor side operation panel 20 is permitted. That is, when the upper floor side operation panel 20 is operated, the escalator 1 starts the ascending operation and the descending operation. At this time, even if the lower floor side operation panel 30 is operated, the escalator 1 does not start the ascending operation and the descending operation. Similarly, when the switch lever is in the “down” position, the operation control of the escalator 1 based on the operation of the lower floor side operation panel 30 is permitted. Further, when the switch lever is in the “normal” position, the escalator 1 starts the ascending operation and the descending operation regardless of which of the upper floor side operation panel 20 and the lower floor side operation panel 30 is operated.

  The control unit 45 stores the operation control circuit of the escalator 1, and switches on and off the corresponding switch of the operation control circuit based on the control signals from the safety SW 42, the inspection SW 43, and the operation panel selection SW 44. To control the operation. The control unit 45 controls the escalator 1 to start the ascending operation and the descending operation based on the operation on the upper floor side operation panel 20 and the lower floor side operation panel 30, and based on the operation in the inspection SW 43, the escalator 1 Escalator 1 based on the operation by the operation panel selected from the upper floor side operation panel 20 and the lower floor side operation panel 30 based on the operation in the operation panel selection SW 44. The operation control of the escalator 1 based on the operation by the operation panel not selected is permitted.

  Based on the control signals from the upper floor side operation panel 20 and the lower floor side operation panel 30, the control unit 45 transmits a control signal that causes the escalator 1 to start an ascending operation and a descending operation. When receiving the control signal for starting the ascending operation from the upper floor side operation panel 20 and the lower floor side operation panel 30, the control unit 45 transmits a control signal in the positive direction to the motor 8. Further, when receiving the control signal for starting the descent operation from the upper floor side operation panel 20 and the lower floor side operation panel 30, the control unit 45 transmits a control signal in the reverse direction to the motor 8.

  The control unit 45 transmits a control signal for switching on / off of the safety circuit 46 based on the control signal from the safety SW 42. Specifically, when the control unit 45 receives the “ON” control signal of the safety circuit 46 from the safety SW 42, the control circuit 45 turns on the safety circuit 46 in the operation control circuit to form an operation control circuit incorporating the safety circuit 46. . When the control unit 45 receives the “OFF” control signal for the safety circuit 46 from the safety SW 42, the operation control circuit cuts the safety circuit 46 in the operation control circuit so that the safety circuit 46 is not incorporated.

  Based on the control signal from the inspection SW 43, the control unit 45 transmits a control signal for setting the escalator 1 to “normal operation” or “operation at inspection”. Specifically, when the control unit 45 receives the “normal operation” control signal from the inspection SW 43, the controller 45 escalates with the operation key removed from the key holes of the upper floor operation panel 20 and the lower floor operation panel 30. A control signal for transmitting an operation control circuit for continuing the operation of 1 is transmitted. When the control unit 45 receives the “operation during inspection” control signal from the inspection SW 43, it inserts an operation key into the key holes of the upper floor side operation panel 20 and the lower floor side operation panel 30 selected by the operation panel selection SW 44. In the state where the escalator 1 is in the ascending operation and the descending operation, and the operation key is removed from the key hole, the escalator 1 transmits a control signal for the operation control circuit to be stopped.

  Based on the control signal from the operation panel selection SW 44, the control unit 45 permits the operation control of the escalator 1 based on the operation by the operation panel selected from the upper floor operation panel 20 and the lower floor operation panel 30. A control signal for controlling the operation control of the escalator 1 based on an operation with an unselected operation panel is transmitted. Specifically, when receiving a control signal for selecting the upper floor side operation panel 20 from the operation panel selection SW 44, the control unit 45 invalidates (ignores) the control signal from the lower floor side operation panel 30. A circuit. When the control unit 45 receives the control signal for selecting the lower floor side operation panel 30 from the operation panel selection SW 44, the control unit 45 sets the operation control circuit to invalidate the control signal from the upper floor side operation panel 20. The control unit 45 is an operation control circuit that validates the control signal from either the upper floor side operation panel 20 or the lower floor side operation panel 30 when receiving the control signal for selecting normal from the operation panel selection SW 44.

  The controller 45 performs the following processing in the operation control circuit of the escalator 1 while the escalator 1 is in operation. While the escalator 1 is in operation, the control unit 45 constantly monitors reception of control signals from the upper floor side operation panel 20, the lower floor side operation panel 30, and the control panel 41.

  The controller 45 determines whether or not an “ON” control signal has been received from the safety SW 42 (step S11). When it is determined that the control signal “OFF” is received from the safety SW 42 (“NO”), the control unit 45 proceeds to step S20. Thus, in the escalator 1 according to the embodiment, the safety circuit 46 is turned on while the safety SW 42 is set to “ON” during the operation of the escalator 1.

  When it is determined that the control signal “ON” is received from the safety SW 42 (in the case of “Yes”), the control unit 45 incorporates the safety circuit 46 in the operation control circuit (step S12). And the control part 45 determines whether the control signal of "operation at the time of inspection" was received from inspection SW43 (step S13). When it is determined that the control signal of “normal operation” is received from the inspection SW 43 (in the case of “No”), the control unit 45 proceeds to step S14 and sets the operation control circuit for normal operation (step S14).

  When it is determined that the control signal “operation at inspection” is received from the inspection SW 43 (in the case of “Yes”), the control unit 45 sets the operation control circuit for operation at inspection (step S15). Then, the control unit 45 controls whether or not the upper floor side operation panel 20 and the lower floor side operation panel 30 can be operated based on the control signal from the operation panel selection SW 44 (step S16). Specifically, when receiving a control signal for selecting the upper floor side operation panel 20 from the operation panel selection SW 44, the control unit 45 sets the operation control circuit to invalidate the control signal from the lower floor side operation panel 30. When the control unit 45 receives the control signal for selecting the lower floor side operation panel 30 from the operation panel selection SW 44, the control unit 45 sets the operation control circuit to invalidate the control signal from the upper floor side operation panel 20. The control unit 45 is an operation control circuit that validates the control signal from either the upper floor side operation panel 20 or the lower floor side operation panel 30 when receiving the control signal for selecting normal from the operation panel selection SW 44.

  Then, has the control unit 45 received the control signals for starting the ascending operation and starting the descending operation from the operation start SW 22 of the upper floor operation panel 20 and the operation start SW 32 of the lower floor operation panel 30 selected in step S16? It is determined whether or not (step S17). When it is determined that the control signal for starting the ascending operation and starting the descending operation is not received (in the case of “No”), the control unit 45 continues to monitor the control signal and waits.

  When it is determined that the control signal for starting the ascending operation and starting the descending operation is received (in the case of “Yes”), the control unit 45 controls the operation of the escalator 1 (step S18). Specifically, based on the control signals from the selected upper floor side operation panel 20 and lower floor side operation panel 30, the control unit 45 sends a control signal for starting the ascending operation and starting the descending operation of the escalator 1 to the motor 8. Send to.

  Whether the control unit 45 has finished receiving control signals for starting up and starting down from the operation start SW 22 of the selected upper floor operation panel 20 and the operation start SW 32 of the lower floor operation panel 30. It is determined whether or not (step S19). When it is determined that the control signal for starting the ascending operation and starting the descending operation is received (in the case of “No”), the control unit 45 returns to step S18 and continues the operation control of the escalator 1.

  When it is determined that the control signal for starting the ascending operation and starting the descending operation has ended (in the case of “Yes”), the control unit 45 controls the escalator 1 to stop (step S20). Specifically, the control unit 45 transmits a control signal for stopping the escalator 1 to the speed reducer 6.

  Further, a safety circuit 46 is incorporated in the operation control circuit of the control unit 45 so as to be freely turned on and off. The safety circuit 46 performs control to stop the escalator 1 when a safety device (not shown) detects a state in which the degree of safety is reduced during the operation of the escalator 1. Here, the safety device is, for example, a sensor that detects a state in which a foreign object including clothes and footwear is sandwiched between the escalator 1 (a state in which the degree of safety is reduced). The operation control circuit incorporating the safety circuit 46 transmits a control signal for stopping the escalator 1 to the speed reducer 6 when the safety device detects a state where the safety level is reduced during the operation of the escalator 1. .

  The escalator 1 which concerns on embodiment consists of the above structures, and demonstrates the effect | action below.

  A case where the step 5 of the escalator 1 is moved by several steps for the inspection work will be described. Here, the step 5 of the escalator 1 is moved in the upward direction.

  First, the worker installs a work entry prohibition fence at the upper floor entrance 10 and the lower floor entrance 11. The operator moves the switch lever of the safety SW 42 of the control panel 41 disposed in the upper floor side machine room to the “ON” position, and turns on the safety circuit 46. Then, the operator moves the switch lever of the inspection SW 43 of the control panel 41 to the “inspection” position to set the escalator 1 to the operation at the time of inspection. Then, the operator moves the switch lever of the operation panel selection SW 44 of the control panel 41 to the “up” position, and permits the operation control of the escalator 1 based on the operation of the upper floor side operation panel 20. Further, the operator confirms that the operation is not performed carelessly with the upper floor side operation panel 20 as a monitoring target.

  Next, the operator inserts the operation key into the key hole of the upper floor side operation panel 20 and maintains the state in which the operation key is rotated to the “UP” position, and the escalator 1 is moved up by a predetermined number of steps. Let When the operator visually confirms that the escalator 1 has been lifted by a predetermined number of steps, the operator removes the operation key from the key hole of the upper floor operation panel 20 and stops the escalator 1. Then, the operator checks the escalator 1.

  When the inspection is completed, the operator inserts the operation key into the key hole of the upper floor side operation panel 20 and maintains the state in which the operation key is rotated to the “UP” position, and the escalator 1 is moved to a predetermined number of stages. Drive up. In this way, the worker performs maintenance and inspection while moving the escalator 1 by a predetermined number of steps.

  Further, when the operator permits the operation control of the escalator 1 based on the operation of the upper floor side operation panel 20 by the operation panel selection SW 44, the operator accidentally inserts the operation key into the key hole of the lower floor side operation panel 30. Even if operated, the escalator 1 cannot be started to start up or down.

  The escalator 1 according to the embodiment is configured as described above, and the effects thereof will be described below.

  The escalator 1 according to the embodiment is configured such that a control panel that permits operation control of the escalator 1 based on an operation of starting the escalator 1 and starting the descent operation at the time of inspection work is selected by the operation panel selection SW 44, It can be limited to any of the lower floor side operation panels 30. As a result, the operation on either the upper floor side operation panel 20 or the lower floor side operation panel 30 that permits the operation control of the escalator 1 based on the operation only needs to be monitored. Even when the operation is performed, monitoring and confirmation of operations on the operation panel becomes easy.

  Further, the operation control of the escalator 1 based on operations other than the operations from the upper floor side operation panel 20 and the lower floor side operation panel 30 where the operation control of the escalator 1 based on the operation is permitted is not permitted. For this reason, even if the operation key is possessed, it is possible to prevent the passenger conveyor from being controlled by operating the upper floor side operation panel 20 and the lower floor side operation panel 30 where the operation control of the escalator 1 based on the operation is not permitted. it can. For this reason, it is possible to more easily prevent the escalator 1 from being erroneously started in the ascending operation and the descending operation during the inspection work. Thus, the escalator 1 according to the embodiment can perform inspection work more safely.

  In embodiment mentioned above, the escalator which conveys a passenger across a lower floor and an upper floor is shown as a passenger conveyor. However, in the present invention, the passenger conveyor may be applied to a so-called moving sidewalk having continuously flat steps.

  The safety circuit may be as follows. Specifically, while the operation key is inserted into the key holes of the upper floor side operation panel 20 and the lower floor side operation panel 30 where the operation control of the escalator 1 based on the operation is permitted, the safety SW 42 is operated. First, it is assumed that the safety circuit 46 is turned on. Specifically, in the flowchart shown in FIG. 5, the determination in step S <b> 11 is unnecessary, and the control unit 45 incorporates the safety circuit 46 after the process in step S <b> 17 and before the process in step S <b> 18. Processing to make a circuit. In this way, even if the operator forgets to operate the safety SW 42, the safety circuit 46 is reliably turned on. For this reason, the introduction of the safety circuit 46 is a double countermeasure, and when the escalator 1 is controlled during inspection, the safety circuit 46 is always incorporated in the operation control circuit, so that a human error can be prevented.

  Although a plurality of embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
