The landing door opening detection devices 6 are provided corresponding to the installation positions of the landing doors 1 b. For example, each of the landing door opening detection devices 6 is formed of a relay circuit.
Each of the landing door opening detection devices 6 has a power supply 8, a b-contact 9 for landing door opening detection, and an a-contact 10 for door opening area detection. Each power supply 8 is provided so as to be able to receive power supply from the outside. Each landing door opening detection b-contact 9 is provided so as to be capable of changing the open/closed state according to the open/closed state of the landing door 1b corresponding to the floor. The b-contacts 9 for detecting the door opening of each landing are connected in series with each other. Each of the door opening allowable area detection a-contacts 10 is connected between the 2 nd door opening allowable area detection circuit 5 of the corresponding floor and the reference potential point. The a-contact 10 for detecting the door opening area is the a-contact of the RLOK relay. When the 1 st door opening permission area detector 2 detects the 1 st floor at which the car 1 stops, the RLOK relay is engaged in response to a command from the control panel 7.
The landing door opening detection devices 6 each have a 1 st coil 11, a 2 nd coil 12, and a 3 rd coil 13. The 1 st coil 11 is connected between the door opening allowable area detection a-contact 10 and a reference potential point. Each 2 nd coil 12 is connected between the 1 st door opening permitting area detecting circuit 4 and a reference potential point.

The 1 st coil b-contacts 14 are connected between the power supplies 8 and the 3 rd coils 13. The 1 st coil 1a contact 15 is connected between each of the door opening allowable area detection a contacts 10 and each of the 1 st coils 11. The 1 st coil is connected between the 1 st door opening permitting region detecting circuit 4 and each 2 nd coil 12 with the 2 nd contact 16. The 1 st coil 3a contact 17 is connected in parallel to the landing door open detection b contact 9.
The landing door opening detection devices 6 each have a 2 nd coil b-contact 18, a 2 nd coil 1 a-contact 19, and a 2 nd coil 2 a-contact 20. The 2 nd coil b-contacts 18 are connected between the 1 st coil b-contacts 14 and the 3 rd coils 13. The 2 nd coil 1a contacts 19 are connected between the 1 st coil 2a contacts 16 and the 2 nd coils 12. The 2 nd coil 2a contacts 20 are connected in parallel to the landing door open detection b contacts 9. The 2 nd coil 2 nd contact points 20 are connected in series with the 1 st coil 3 rd contact point 17.
The landing door opening detection devices 6 each have a 1a contact 21 for the 3 rd coil, a 2a contact 22 for the 3 rd coil, a 3a contact 23 for the 3 rd coil, and a b contact 24 for the 3 rd coil.

The 1 st-a-contact 21 for the 3 rd coil is connected in parallel to the 1 st-a-contact 15 for the 1 st coil. The 3 rd coil 2a contacts 22 are connected between the 1 st coil 2a contacts 16 and the 2 nd coils 12. The 2 nd contact 22 for the 3 rd coil is connected in parallel with the 1 st contact 19 for the 2 nd coil. The 3 rd coil 3 rd contact 23 is connected between the power supply 8 and the 2 nd coil b contact 18. The 3 rd coil 3 rd contact 23 is connected in parallel to the 1 st coil b contact 14. Each 3 rd coil b-contact 24 is connected in parallel to each landing door opening detection b-contact 9. The 3 rd coil b-contact 24 is connected in series to the 1 st coil 3 a-contact 17 and the 2 nd coil 2 a-contact 20.
The control panel 7 controls the whole elevator. For example, the control panel 7 controls the raising and lowering of the car 1.
In the elevator system, a plurality of door opening permission areas are set respectively corresponding to installation positions of the landing doors 1 b. The door opening permission areas are set at positions at which the car door 1a and the landing door 1b can be opened at the corresponding floors.
When the car 1 does not enter the door opening permitted area of any floor, the 1 st door opening permitted area detecting circuit 4 does not detect any 1 st door opening permitted area detector 2. At this time, the 1 st door opening permission area detection circuit 4 does not transmit the door opening permission area entry signal B indicating that the car 1 enters the door opening permission area to the control panel 7. The control panel 7 detects that the car 1 does not enter the door opening permission area of any floor, based on the absence of the door opening permission area entry signal B.
At this time, all the 2 nd door opening permission area detection circuits 5 do not detect the 2 nd door opening permission area detector 3. When all the 2 nd door open permitted area detection circuits 5 do not detect the 2 nd door open permitted area detector 3, no power is supplied to the primary side of all the door open permitted area detection a-contacts 10.
When the primary side of all the door opening permission area detection a-contacts 10 is not supplied with power, the 1 st coil 11 corresponding to the floor is demagnetized. When all the 1 st coils 11 are demagnetized, all the 1 st coils are closed by the b-contact 14. All 1 st coils are opened with 2a contacts 16. When all the 1 st coils are opened by the 2 nd contact 16, all the 2 nd coils 12 are demagnetized. When all 2 nd coils 12 are demagnetized, all 2 nd coils are closed with the b-contact 18. When the b-contact 18 for the 2 nd coil of the corresponding floor is closed, the 3 rd coil 13 is excited.
As a result, all of the 1 st coil 3a contacts 17, all of the 2 nd coil 2a contacts 20, and all of the 3 rd coil b contacts 24 are opened. Therefore, both sides of all the landing door open detection b-contacts 9 are not short-circuited.
When the car 1 enters the door opening permission area of any floor, the 1 st door opening permission area detection circuit 4 detects the 1 st door opening permission area detector 2 of the corresponding floor. At this time, the 1 st open door permitted region detection circuit 4 transmits an open door permitted region entry signal B. The control panel 7 detects that the car 1 enters the door opening permitted area of any floor upon receiving the door opening permitted area entering signal B.
At this time, the 2 nd door opening permitted area detection circuit 5 of the corresponding floor detects the 2 nd door opening permitted area detector 3. When the 2 nd door opening permission area detection circuit 5 of the corresponding floor detects the 2 nd door opening permission area detector 3, power is supplied to the primary side of the a contact 10 for door opening permission area detection of the corresponding floor.
When power is supplied to the primary side of the a-contact 10 for detecting the door opening allowable area of the corresponding floor, the 1 st coil 11 of the corresponding floor is excited. When the 1 st coil 11 of the corresponding floor is excited, the 1 st coil of the corresponding floor is closed with the 2 nd contact 16. When the 1 st coil of the corresponding floor is closed with the 2 nd contact 16, the 2 nd coil 12 of the corresponding floor is excited. When the 2 nd coil 12 corresponding to the floor is excited, the 2 nd coil b-contact 18 corresponding to the floor is opened. When the b-contact 18 for the 2 nd coil corresponding to the floor is opened, the 3 rd coil 13 is demagnetized.
As a result, the 1 st coil corresponding to the floor is closed with the 3a contact 17, the 2 nd coil corresponding to the floor is closed with the 2a contact 20, and the 3 rd coil corresponding to the floor is closed with the b contact 24. Therefore, both sides of the b-contact 9 for landing door opening detection corresponding to the floor are short-circuited.
In this state, the control panel 7 opens the landing door 1b of the corresponding floor. When the landing door 1b of the corresponding floor is opened, the landing door opening detection b-contact 9 of the corresponding floor is opened. At this time, the conduction of the wiring connecting the plurality of landing door opening detection b-contacts 9 in series is not cut. As a result, the wiring connecting the plurality of landing door open detection b-contacts 9 in series maintains a predetermined voltage. In this case, any of the landing door opening detection devices 6 does not transmit the landing door opening detection signal a indicating that the landing door 1b is open to the control panel 7. The control panel 7 detects that none of the landing doors 1b of any floor is open to the car 1 when the landing door open detection signal a is not received.
On the other hand, when the landing door 1b of a floor other than the corresponding floor is opened for some reason, the b-contact 9 for landing door opening detection of the floor is turned off. At this time, the conduction of the wiring connecting the plurality of landing open detection b-contacts 9 in series is cut off. Therefore, the landing door open detection signal a is transmitted. The control panel 7 detects that the landing door 1b of a floor other than the floor where the car 1 enters the door opening permission area is opened, based on the landing door opening detection signal a.
When the car 1 leaves the door opening permission area of any floor, the 1 st door opening permission area detection circuit 4 does not detect the 1 st door opening permission area detector 2 of the corresponding floor. At this time, the 1 st open door permitted region detection circuit 4 does not transmit the open door permitted region entry signal B. The control panel 7 detects that the car 1 does not enter the door opening permitted area of any floor, based on the absence of reception of the door opening permitted area entry signal B.
At this time, the 2 nd door-opening allowable area detection circuit 5 of the corresponding floor does not detect the 2 nd door-opening allowable area detector 3. When the 2 nd door-opening permission area detection circuit 5 of the corresponding floor does not detect the 2 nd door-opening permission area detector 3, the primary side of the a-contact 10 for door-opening permission area detection of the corresponding floor is not supplied with power.
When the power is not supplied to the primary side of the a-contact 10 for detecting the door opening allowable area corresponding to the floor, the 1 st coil 11 corresponding to the floor is demagnetized. When the 1 st coil 11 corresponding to the floor is demagnetized, the 1 st coil corresponding to the floor is opened by the 2 nd a contact 16. When the 1 st coil of the corresponding floor is turned off by the 2 nd contact 16, the 2 nd coil 12 of the corresponding floor is demagnetized. When the 2 nd coil 12 corresponding to the floor is demagnetized, the 2 nd coil corresponding to the floor is closed by the b-contact 18. When the b-contact 18 for the 2 nd coil of the corresponding floor is closed, the 3 rd coil 13 is excited.
As a result, the 1 st coil 3a contact 17, the 2 nd coil 2a contact 20, and the 3 rd coil b contact 24 of the corresponding floor are opened. Therefore, both sides of the b-contact 9 for landing door opening detection corresponding to the floor are not short-circuited.
For example, there are cases where the following failures occur: when the car 1 enters the door opening permission area of the corresponding floor, the 1 st coil 11 of the corresponding floor is always excited. In this case, even when the car 1 leaves the door opening permission area of the corresponding floor, the 1 st coil b-contact 14 of the corresponding floor is not closed. As a result, the 3 rd coil 13 is not excited. Thereafter, even when the car 1 enters the door opening allowable area of the corresponding floor again, the 2 nd coil 12 is not excited. Therefore, the 2 nd coil 2 nd contact 20 is not closed.
In this state, when the landing door 1b of the corresponding floor is opened, the landing door open detection b-contact 9 of the corresponding floor is opened. At this time, the conduction of the wiring connecting the plurality of landing open detection b-contacts 9 in series is cut off. Therefore, the landing door open detection signal a is transmitted. The control panel 7 detects a failure of any of the landing door opening detection devices 6 based on the reception of the landing door opening detection signal a.
For example, there are cases where the following failures occur: when the car 1 leaves the door opening permission area of the corresponding floor, the 1 st coil 11 of the corresponding floor is demagnetized all the time. In this case, even when the car 1 enters the door opening allowable area of the corresponding floor, the 1 st coil 2a contact 16 is not closed. Therefore, the 2 nd coil 12 is not excited. When the 2 nd coil 12 is not excited, the 2 nd coil b-contact 18 is not opened. When the 2 nd coil b contact 18 is not opened, the 3 rd coil 13 is not demagnetized. Therefore, the 2 nd coil 2a contact 20 and the 3 rd coil b contact 24 are not closed.
In this state, when the landing door 1b of the corresponding floor is opened, the landing door open detection b-contact 9 of the corresponding floor is opened. At this time, the conduction of the wiring connecting the plurality of landing open detection b-contacts 9 in series is cut off. Therefore, the landing door open detection signal a is transmitted. The control panel 7 detects a failure of any of the landing door opening detection devices 6 based on the reception of the landing door opening detection signal a.
For example, there are cases where the following failures occur: when the car 1 enters the door opening permission area of the corresponding floor, the 2 nd coil 12 of the corresponding floor is always excited. In this case, even when the car 1 leaves the door opening permission area of the corresponding floor, the 2 nd coil b-contact 18 of the corresponding floor is not closed. As a result, the 3 rd coil 13 is not excited. Thereafter, even when the car 1 enters the door opening permission area of the corresponding floor again, the 1 st coil 11 is not excited. Therefore, the 1 st coil 3a contact 17 is not closed.
In this state, when the landing door 1b of the corresponding floor is opened, the landing door open detection b-contact 9 of the corresponding floor is opened. At this time, the conduction of the wiring connecting the plurality of landing open detection b-contacts 9 in series is cut off. Therefore, the landing door open detection signal a is transmitted. The control panel 7 detects a failure of any of the landing door opening detection devices 6 based on the reception of the landing door opening detection signal a.
For example, there are cases where the following failures occur: when the car 1 leaves the door opening permission area of the corresponding floor, the 2 nd coil 12 of the corresponding floor is demagnetized all the time. In this case, even when the car 1 enters the door opening allowable area of the corresponding floor, the 2 nd coil 1a contact 19 is not closed. Therefore, the 2 nd coil 12 is not excited. When the 2 nd coil 12 is not excited, the 2 nd coil b-contact 18 is not opened. When the 2 nd coil b contact 18 is not opened, the 3 rd coil 13 is not demagnetized. Therefore, the 2 nd coil 2a contact 20 and the 3 rd coil b contact 24 are not closed.
In this state, when the landing door 1b of the corresponding floor is opened, the landing door open detection b-contact 9 of the corresponding floor is opened. At this time, the conduction of the wiring connecting the plurality of landing open detection b-contacts 9 in series is cut off. Therefore, the landing door open detection signal a is transmitted. The control panel 7 detects a failure of any of the landing door opening detection devices 6 based on the reception of the landing door opening detection signal a.
For example, there are cases where the following failures occur: when the car 1 leaves the door opening permission area of the corresponding floor, the 3 rd coil 13 of the corresponding floor is always excited. In this case, even when the car 1 enters the door opening permission area of the corresponding floor, the 3 rd coil b-contact 24 is not closed.
In this state, when the landing door 1b of the corresponding floor is opened, the landing door open detection b-contact 9 of the corresponding floor is opened. At this time, the conduction of the wiring connecting the plurality of landing open detection b-contacts 9 in series is cut off. Therefore, the landing door open detection signal a is transmitted. The control panel 7 detects a failure of any of the landing door opening detection devices 6 based on the reception of the landing door opening detection signal a.
For example, there are cases where the following failures occur: when the car 1 enters the door opening permission area of the corresponding floor, the 3 rd coil 13 of the corresponding floor is demagnetized all the time. Thereafter, even when the car 1 enters the door opening allowable area of the corresponding floor, the 1 st coil 11 is not excited. When the 1 st coil 11 is not excited, the 1 st coil 2a contact 16 is not closed. When the 1 st coil 2a contact 16 is not closed, the 2 nd coil 12 is not excited. Therefore, the 1 st coil 3a contact 17 and the 2 nd coil 2a contact 20 are not closed.
In this state, when the landing door 1b of the corresponding floor is opened, the landing door open detection b-contact 9 of the corresponding floor is opened. At this time, the conduction of the wiring connecting the plurality of landing open detection b-contacts 9 in series is cut off. Therefore, the landing door open detection signal a is transmitted. The control panel 7 detects a failure of any of the landing door opening detection devices 6 based on the reception of the landing door opening detection signal a.
Next, the operation of the control panel 7 will be described with reference to fig. 2.
Fig. 2 is a flowchart for explaining the operation of the control panel of the elevator system according to embodiment 1 of the present invention.
In step S1, the control panel 7 determines whether or not the landing door open detection signal a is received. When the control panel 7 does not receive the landing door open detection signal a in step S1, step S1 is repeated. When the control panel 7 receives the landing door open detection signal a in step S1, the flow proceeds to step S2.
In step S2, the control panel 7 determines whether or not the door opening permission area entry signal B is received.
When the control panel 7 receives the door opening allowing area entering signal B in step S2, the process proceeds to step S3. In step S3, the control panel 7 detects a failure of any one of the landing door opening detection devices 6. At this time, the control panel 7 prohibits the travel of the car 1. Specifically, the control panel 7 stops the car 1 by the 1 st braking force. Then, the control panel 7 ends the operation.
If the control panel 7 does not receive the door opening allowing area entering signal B in step S2, the process proceeds to step S4. In step S4, the control panel 7 stops the car 1 by the 2 nd braking force. For example, the value of the 2 nd braking force is set to a value smaller than the value of the 1 st braking force. Then, the control panel 7 ends the operation.
According to embodiment 1 described above, when the car 1 enters the door opening permission area of the corresponding floor, the landing door opening detection device 6 short-circuits both sides of the corresponding landing door opening detection b-contact 9. Therefore, even when the car door 1a and the landing door 1b are opened at the stop floor of the car 1, it can be detected that the landing door 1b is opened at a floor other than the stop floor of the car 1.
The control panel 7 prohibits the travel of the car 1 when detecting a failure of any of the landing door opening detection devices 6. Therefore, the contact of the maintenance person with the car 1 when the maintenance person enters the hoistway can be suppressed.
When the door opening permission area entry signal B is not received when the landing door opening detection signal a is received, the control panel 7 stops the car 1 by the 2 nd braking force, and the value of the 2 nd braking force is set to be smaller than the value of the 1 st braking force. Therefore, the traveling car 1 gradually decelerates. As a result, even when a user is present inside the car 1, it is possible to suppress an excessive inertial force from acting on the user.
Each of the landing door opening detection devices 6 is formed of a relay circuit. Each of the landing door-open detection devices 6 does not short-circuit both sides of the corresponding landing door-open detection b-contact 9 when the car 1 enters the door-open allowed area of the corresponding floor when the corresponding relay circuit has a failure. In this case, when the corresponding landing door 1b is opened, the landing open-door detection signal a is transmitted. Therefore, it is not necessary to diagnose the malfunction of the landing door opening detection device 6 from the outside. As a result, it is possible to detect a failure of the landing door opening detection device 6 with a minimum configuration.
Further, at least one landing door-open detection device 6 of the plurality of landing door-open detection devices 6 may be configured by a relay circuit. In this case, when the car 1 enters the door opening permission area of the corresponding floor when the corresponding relay circuit has a failure, the landing door opening detection device 6 does not short-circuit both sides of the corresponding landing door opening detection b-contact 9. In this case, when the corresponding landing door 1b is opened, the landing open-door detection signal a is transmitted. Therefore, it is not necessary to diagnose the malfunction of the landing door opening detection device 6 from the outside. As a result, the malfunction of the landing door opening detection device 6 can be detected with a minimum configuration.
Next, an example of the control panel 7 will be described with reference to fig. 3.
Fig. 3 is a hardware configuration diagram of a control panel of the elevator system according to embodiment 1 of the present invention.
The main function of the control panel 7 can be realized by the processing circuit. For example, the processing circuit has at least one processor 25a and at least one memory 25 b. For example, the processing circuitry has at least one dedicated hardware 26.
In case the processing circuitry has at least one processor 25a and at least one memory 25b, the main function of the control board 7 is realized by 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 the firmware is stored in the at least one memory 25 b. The at least one processor 25a realizes the main functions of the control panel 7 by reading out and executing programs stored in the at least one memory 25 b. The at least one processor 25a is also referred to as a CPU (Central Processing Unit), a Central Processing Unit, a Processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. For example, the at least one Memory 25b is a nonvolatile or volatile semiconductor Memory such as a RAM (Random access Memory), a ROM (Read-Only Memory), a flash Memory, an EPROM (erasable Programmable Read-Only Memory), an EEPROM (electrically erasable Programmable Read-Only Memory), a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD (Digital versatile disk), or the like.
In case of a processing circuit with at least one dedicated hardware 26, the processing circuit is for example realized by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA or a combination thereof. For example, the main functions of the control board 7 are realized by respective processing circuits. For example, the main functions of the control panel 7 are implemented in a unified manner by the processing circuit.
Regarding the main functions of the control panel 7, it is also possible that one part is implemented by dedicated hardware 26 and the other part is implemented by software or firmware. For example, the function of raising and lowering the car 1 may be realized by a processing circuit as the dedicated hardware 26, and the function other than the function of raising and lowering the car 1 may be realized by the at least one processor 25a reading and executing a program stored in the at least one memory 25 b.
In this way, the processing circuitry can implement the functionality of the control device via hardware 26, software, firmware, or a combination thereof.
