The mode for carrying out the invention is explained in accordance with the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals. Repeated explanation of this portion is appropriately simplified or omitted.
Fig. 1 is a configuration diagram of a passenger conveyor system to which a control device for a passenger conveyor according to embodiment 1 of the present invention is applied.
The passenger conveyor of fig. 1 is an escalator. For example, passenger conveyors are provided to cross from one side of adjacent floors of a building to another. The lower landing entrance 1 is provided at the lower portion of the passenger conveyor. The lower landing entrance 1 is provided at a floor below an adjacent floor. The upper landing entrance 2 is provided at an upper portion of the passenger conveyor. The upper landing entrance 2 is provided at a floor above an adjacent floor.
The lower machine room 3 is provided directly below the lower landing entrance 1. The upper machine room 4 is provided directly below the upper landing entrance 2. The plurality of steps 5 are annularly connected between the lower landing entrance 1 and the upper landing entrance 2.
A pair of skirt panels 6 are provided on both outer sides of the plurality of steps 5. A pair of skirt panels 6 is provided along the length of the passenger conveyor. The pair of moving handrails 7 are annularly provided on both outer sides of the plurality of steps 5.
One of the pair of user detection devices 8 is provided at the lower landing entrance 1. The other of the pair of user detection devices 8 is provided at the upper landing entrance 2. One of the pair of handrail speed detecting devices 9 is provided on one side of the pair of aprons 6. The other of the pair of handrail speed detecting devices 9 is provided on the other side of the pair of aprons 6.
The decelerator 10 is provided in the upper machine room 4. The governor 11 is provided in the upper machine room 4. The motor 12 is provided in the upper machine room 4. The brake 13 is provided in the upper machine room 4. The control device 14 is provided in the upper machine room 4.
The monitoring center 15 is provided outside the building where the passenger conveyor is provided. For example, the monitoring center 15 is provided at a maintenance company of the passenger conveyor.
In the passenger conveyor, the control device 14 rotates the motor 12. The decelerator 10 operates according to the rotation of the motor 12. The plurality of steps 5 are cyclically moved according to the operation of the decelerator 10. The pair of moving handrails 7 circularly move according to the operation of the decelerator 10. As a result, the pair of moving handrails 7 can cyclically move in synchronization with the plurality of steps 5.
At this time, the pair of user detection devices 8 detect the user using the passenger conveyor. Specifically, one of the pair of user detection devices 8 detects a user by blocking light emitted from the lower entrance 1. The other of the pair of user detection devices 8 detects a user by blocking light emitted from the upper entrance 2.
A pair of handrail speed detecting means 9 detects the speed of moving the handrail 7. Specifically, one of the pair of handrail speed detection devices 9 detects the speed of one of the pair of moving handrails 7. The other of the pair of handrail speed detecting devices 9 detects the speed of the other of the pair of moving handrails 7.
The control device 14 controls the passenger conveyor based on the detection results of the pair of user detection devices 8 and the detection results of the pair of handrail speed detection devices 9. For example, when both of the pair of user detection devices 8 do not detect a user, the control device 14 performs control for confirming the detection accuracy of the pair of handrail speed detection devices 9. At this time, when there is an abnormality in the control based on the detection results of the pair of handrail speed detection devices 9, the control device 14 transmits information indicating the abnormality to the monitoring center 15 via the public line 16.
Next, emergency stop of the passenger conveyor will be described with reference to fig. 2 and 3.
Fig. 2 is a side view of a speed governor of a passenger conveyor to which a control device of the passenger conveyor according to embodiment 1 of the present invention is applied. Fig. 3 is a sectional view taken along line a-a of fig. 2.
As shown in fig. 2 and 3, the governor 11 has a disc 11a, a kick pin 11b, a spring 11c, a lever 11d, a switch 11e, and a sensor 11 f.
The disk 11a is attached to a rotating shaft of the reduction gear 10 not shown in fig. 2 and 3. The kick pin 11b is disposed on the outer peripheral side of the disc 11 a. One side of the spring 11c is fixed to the disc 11 a. The other side of the spring 11c is fixed to the recoil pin 11 b. The rod 11d is disposed radially outward of the disk 11 a. The switch 11e is provided corresponding to the lever 11 d. The sensor 11f is configured to pass 2 portions of the rotating disk 11 a.
The kick pin 11b moves radially outward of the disk 11a by centrifugal force according to the rotation speed of the disk 11 a. When the speed of the passenger conveyor reaches 120% to 130% of the rated speed, the kick pin 11b contacts the lever 11 d. As a result, the rod 11d is toppled. When the lever 11d is tilted, the switch 11e is operated.
At this time, the control device 14 not shown in fig. 2 and 3 operates the brake 13 not shown in fig. 2 and 3. As a result, the passenger conveyor is stopped urgently.
The sensor 11f generates a pulse at the moment the disc 11a cuts the magnetic field.
At this time, the control device 14 monitors the speed of the passenger conveyor based on the pulse. When the speed of the passenger conveyor becomes 20% or less of the rated speed, the control device 14 operates the brake 13. As a result, the passenger conveyor is stopped urgently.
Next, the handrail speed detection device 9 will be described with reference to fig. 4 to 6.
Fig. 4 is a front view of a handrail speed detection device of a passenger conveyor to which a control device of the passenger conveyor according to embodiment 1 of the present invention is applied. Fig. 5 is a side view of a handrail speed detection device of a passenger conveyor to which a control device of the passenger conveyor according to embodiment 1 of the present invention is applied. Fig. 6 is a plan view of a handrail speed detection device of a passenger conveyor to which a control device of the passenger conveyor according to embodiment 1 of the present invention is applied.
As shown in fig. 4 to 6, the handrail speed detecting device 9 includes a roller 9a, a disk 9b, and a non-contact switch 9 c.
The outer periphery of the roller 9a is arranged to contact the inner surface of the moving handrail 7 on the return side. The disc 9b is provided to the rotation shaft of the roller 9 a. The non-contact switch 9c is configured to be traversed by the disk 9 b.
When the roller 9a comes into contact with the moving handrail 7, the roller 9a rotates at a speed corresponding to the moving speed of the moving handrail 7. The disc 9b rotates at the same rotational speed as the roller 9 a. The non-contact switch 9c generates a pulse corresponding to the rotation speed of the disk 9 b.
When the time duration of the pulse interval, which is longer than the preset interval, continues for a preset time or more, the passenger conveyor is stopped in an emergency. For example, when the pulse interval is an interval corresponding to a speed of 25% or less of the rated speed of the passenger conveyor and the state continues for 0.5 seconds or more, the passenger conveyor is stopped urgently.
Next, a description will be given of example 1 of the mechanism of the handrail speed detecting device 9 with reference to fig. 7 and 8.
Fig. 7 and 8 are side views of example 1 of a handrail speed detection device of a passenger conveyor to which a control device of the passenger conveyor according to embodiment 1 of the present invention is applied.
As shown in fig. 7 and 8, the handrail speed detecting device 9 has a piston 17a and a cylinder 17 b. The handrail speed detecting device 9 controls the contact between the roller 9a and the moving handrail 7 by raising the arm by the operation of the piston 17a and the cylinder 17 b.
Next, a 2 nd example of the mechanism of the handrail speed detecting device 9 will be described with reference to fig. 9 and 10.
Fig. 9 and 10 are side views of example 2 of a handrail speed detection device of a passenger conveyor to which a control device of the passenger conveyor according to embodiment 1 of the present invention is applied.
As shown in fig. 9 and 10, the handrail speed detecting device 9 has an actuator 17 c. The handrail speed detecting device 9 controls the contact of the roller 9a with the moving handrail 7 by lifting the arm by the operation of the actuator 17 c.
Next, a 3 rd example of the mechanism of the handrail speed detecting device 9 will be described with reference to fig. 11 and 12.
Fig. 11 and 12 are side views of example 3 of a handrail speed detection device of a passenger conveyor to which a control device of the passenger conveyor according to embodiment 1 of the present invention is applied.
As shown in fig. 11 and 12, the handrail speed detecting device 9 has a wire 17d and a pulley 17 e. The handrail speed detecting device 9 raises the arm by the operation of the wire 17d wound around the pulley 17e, thereby controlling the contact between the roller 9a and the moving handrail 7.
Next, an outline of the control device 14 will be described with reference to fig. 13.
Fig. 13 is a block diagram of a control device for a passenger conveyor according to embodiment 1 of the present invention.
As shown in fig. 13, the control device 14 includes a receiving unit 14a, a transmitting unit 14b, a storage unit 14c, and a control unit 14 d.
The receiving unit 14a receives information from the outside. For example, when the user detection device 8 detects a user using the passenger conveyor, the receiving unit 14a receives information indicating that the user is detected from the user detection device 8. For example, the receiving unit 14a receives the speed information of the moving handrail 7 from the handrail speed detecting device 9.
The transmission unit 14b transmits information to the outside. For example, when the handrail speed detection device 9 detects a delay in moving the handrail 7, the transmission unit 14b transmits information indicating the delay in moving the handrail 7 to the monitoring center 15.
The storage portion 14c stores information about the passenger conveyor. For example, the storage unit 14c stores information of the measured value of the slip ratio of the moving handrail 7 at the time of the diagnostic operation of the passenger conveyor. For example, the storage unit 14c stores information indicating a stopping distance of the brake 13 to the passenger conveyor at the time of diagnostic operation of the passenger conveyor.
The control unit 14d controls the entire passenger conveyor. For example, when the user detection device 8 detects a user, the control unit 14d starts the operation of the motor 12. For example, when the handrail speed detection device 9 detects a delay in moving the handrail 7, the control unit 14d operates the brake 13 to stop the passenger conveyor.
Next, the operation of the control device 14 will be described with reference to fig. 14 and 15.
Fig. 14 and 15 are flowcharts for explaining the operation of the control device for a passenger conveyor according to embodiment 1 of the present invention.
When the diagnosis operation is started, the control device 14 determines whether or not the user detection device 8 detects a user in step S1. For example, the controller 14 determines whether or not both of the pair of user detection devices 8 detect a user within a time period of 30 seconds added to a time period of one turn of the step 5.
When the user detection device 8 detects the user at step S1, the control device 14 performs the operation of step S1. If the user detection device 8 does not detect a user at step S1, the control device 14 performs the operation of step S2.
In step S2, the control device 14 starts measuring the slip ratio of the moving handrail 7. Then, the control device 14 performs the operation of step S3. In step S3, the control device 14 determines whether or not the user detection device 8 detects a user during one step 5. When the user is detected by the user detection device 8 during one step 5 at step S3, the control device 14 performs the operation of step S1. If the user is not detected by the user detection device 8 during one step 5 in step S3, the control device 14 performs the operation of step S4.
In step S4, the control device 14 stores information of the measured value of the slip ratio of the moving handrail 7. Then, the control device 14 performs the operation of step S5. In step S5, the control device 14 switches to a setting in which, when the handrail speed detection device 9 detects a delay in moving the handrail 7, information indicating the delay in moving the handrail 7 is not transmitted. Then, the control device 14 performs the operation of step S6.
In step S6, the control device 14 releases the contact of the roller 9a with the moving handrail 7. Then, the control device 14 performs the operation of step S7. In step S7, the control device 14 determines whether or not the user detection device 8 has detected a user. When the user detection device 8 detects the user at step S7, the control device 14 performs the operation of step S1. If the user detection device 8 does not detect a user at step S7, the control device 14 performs the operation of step S8. In step S8, the control device 14 determines whether the passenger conveyor is stopped within a preset time.
When the passenger conveyor is stopped in step S8, the control device 14 performs the operation of step S9. In step S9, the control device 14 stores information indicating that the handrail speed detection by the handrail speed detection device 9 is normal and information indicating the stop distance of the stopper 13 to the passenger conveyor. At this time, the control device 14 grasps the stopping distance of the passenger conveyor based on the pulse generated by the non-contact switch 9 c. Then, the diagnostic operation is ended.
If the passenger conveyor is not stopped in step S8, the control device 14 performs the operation of step S10. In step S10, the control device 14 operates the brake 13. Then, the control device 14 performs the operation of step S11. In step S11, the control device 14 transmits information indicating an abnormality to the monitoring center 15. Then, the diagnostic operation is ended.
According to embodiment 1 described above, when the user is not detected, control is performed to confirm the detection accuracy of the handrail speed detection device 9. Therefore, the time for the spot check work of the handrail speed detection device 9 can be shortened.
When the user is detected during the control for confirming the detection accuracy of the handrail speed detection device 9, the control for confirming the detection accuracy of the handrail speed detection device 9 is stopped. Therefore, the user can use the passenger conveyor as usual.
In addition, when control is performed to confirm the detection accuracy of the handrail speed detection device 9, a measurement value of the slip ratio of the moving handrail 7 is stored. Therefore, the measured value of the slip ratio of the moving handrail 7 can be automatically collected.
When the handrail speed detection device 9 detects a delay in moving the handrail 7 during control for confirming the detection accuracy of the handrail speed detection device 9, information indicating the delay in moving the handrail 7 is not transmitted to the outside. Therefore, unnecessary transmission of information indicating a delay in moving the armrest 7 to the monitoring center 15 can be suppressed.
When the passenger conveyor is not stopped for a predetermined time period after the release roller 9a comes into contact with the moving handrail 7 during control for checking the detection accuracy of the handrail speed detection device 9, information indicating an abnormality is transmitted to the outside. Therefore, the monitoring center 15 can grasp a control abnormality based on the detection result of the handrail speed detection device 9.
When the passenger conveyor is not stopped for a predetermined time period after the release roller 9a comes into contact with the moving handrail 7 during control for checking the detection accuracy of the handrail speed detection device 9, the brake 13 is operated. Therefore, the safety during the spot inspection work can be reliably ensured.
Further, information indicating the stopping distance of the stopper 13 to the passenger conveyor is stored. Therefore, information indicating the stopping distance of the stopper 13 to the passenger conveyor can be automatically collected.
In addition, a camera may be used as the user detection device 8. In this case, when the user is not detected, control is performed to confirm the detection accuracy of the handrail speed detection device 9. Therefore, the time for the spot check work of the handrail speed detection device 9 can be shortened.
Next, an example of the control device 14 will be described with reference to fig. 16.

In the case of a processing circuit having at least 1 processor 18a and at least 1 memory 18b, the functions of the control device 14 are implemented in software, firmware or a combination of software and firmware. At least one of the software and the firmware is described as a program. At least one of the software and firmware is stored in at least 1 memory 18 b. The at least 1 processor 18a reads out and executes the program stored in the at least 1 memory 18b, thereby realizing each function of the control device 14. The at least one processor 18a is also referred to as a cpu (central Processing unit), a central Processing unit, a Processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. The memory 18b is, for example, a nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a DVD.
In the case of a processing circuit having at least 1 piece of hardware 19, the processing circuit is implemented, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, a PLD, a CPLD, or a combination thereof. For example, each function of the control device 14 is realized by a processing circuit. For example, the respective functions of the control device 14 are collectively realized by a processing circuit.
The functions of the control device 14 may be partially implemented by hardware 19 and partially implemented by software or firmware. For example, the control unit 14d is realized by a processing circuit as hardware 19, and functions other than the functions of the control unit 14d are realized by at least 1 processor 18a reading and executing programs stored in at least 1 memory 18 b.
Thus, the processing circuitry implements the functions of the control device 14 via hardware 19, software, firmware, or a combination thereof.
