[0007] Problems to be Solved by the Invention

[0008] In the case of a major earthquake occurring in an elevator system, the diagnostic operation may sometimes be determined as "no" and restored by maintenance personnel. At this time, it is possible that the availability of resetting the diagnostic operation may be omitted due to mistakes of the maintenance personnel or the like. Here, the elevator system described in Patent Document 1 does not display information on the restoration performed by the maintenance personnel. Therefore, it is difficult for the maintenance personnel to notice that the reset has been omitted.

[0009] The present invention has been completed to solve such problems. An object of the present invention is to provide a control panel and an elevator system of an elevator that prevent omission of reset of the availability of diagnostic operation during restoration by maintenance personnel.

[0010] Means for Solving the Problems

[0011] The control panel of the elevator of the present invention includes: a state management unit that stores the availability state of the normal operation of the elevator and stores the availability state of the diagnostic operation of the elevator, and when the earthquake detection device detects an earthquake equal to or greater than a first threshold value for determining the availability of normal operation, sets the normal operation to "no", and when the earthquake detection device detects an earthquake equal to or greater than a second threshold value for determining the availability of diagnostic operation, sets the diagnostic operation to "no"; and a transmission unit that, when the normal operation is "yes" and the diagnostic operation is "no", transmits a notification signal indicating that the normal operation is "yes" and the diagnostic operation is "no" to a notification device.

[0012] The elevator system of the present invention includes: a seismic detection device that detects an earthquake above a first threshold for determining whether the elevator can perform normal operation and detects an earthquake above a second threshold for determining whether the elevator can perform diagnostic operation; a notification device that notifies the maintenance personnel of the content indicated by the received notification signal; and a control panel that stores the status of whether normal operation is possible and stores the status of whether diagnostic operation is possible. When the seismic detection device detects an earthquake above the first threshold, the normal operation is set to "no". When the seismic detection device detects an earthquake above the second threshold, the diagnostic operation is set to "no". When the diagnostic operation is "no", a notification signal indicating that the diagnostic operation is "no" is sent to the notification device.

[0013] Advantages of the Invention

[0014] According to these inventions, the control panel sends a notification signal indicating that the normal operation is "yes" and the diagnostic operation is "no" to the notification device. The notification device notifies the maintenance personnel of the content of the received notification signal. Thereby, in the restoration performed by the maintenance personnel, omission of resetting the diagnostic operation availability can be prevented. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] A mode for carrying out the present invention will be described with reference to the accompanying drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and duplicate descriptions are appropriately simplified or omitted.

[0019] Embodiment 1.

[0020] Figure 1 is a structural diagram of the elevator system according to Embodiment 1.

[0021] In Figure 1 a building 1 has a plurality of floors. The elevator system 2 is applied to the building 1.

[0022] The elevator system 2 includes an elevator 3 and a remote monitoring device 4.

[0023] In the elevator 3, a shaft 5 runs through each floor of the building 1. A pit 6 is provided at the lower end of the shaft 5. A machine room 7 is provided above the shaft 5. A plurality of landing stations 8 are provided on each floor of the building 1. The plurality of landing stations 8 are respectively opposite to the shaft 5. The plurality of landing stations 8 are respectively provided with a landing door 9. The plurality of landing stations 8 are respectively provided with a landing indicator 10. The landing indicator 10 notifies the content indicated by the received notification signal by display. The plurality of landing indicators 10 are respectively examples of notification devices. The notification signal is, for example, a signal indicating a matter to be notified to a maintenance personnel.

[0024] The elevator 3 includes a car 11 , a counterweight 12 , a traction machine 13 , a main rope 14 , an earthquake detection device 15 , and a control panel 16 .

[0025] The car 11 is arranged to be able to rise and fall along a guide rail (not shown) inside the hoistway 5. The car 11 has a car door 17 and a car indicator 18. The car door 17 is configured to enable the landing door 9 to be opened and closed in a linked manner when the car 11 stops at any one of a plurality of floors. The car indicator 18 is configured to be able to notify, by display, the content represented by the notification signal received by the car 11. The car indicator 18 is an example of a notification device. The car indicator 18 is arranged above the car door 17.

[0026] The counterweight 12 is provided inside the hoistway 5 so as to be movable up and down along a guide rail (not shown).

[0027] The traction machine 13 is installed in the machine room 7 .

[0028] The main rope 14 is wound around the hoisting machine 13. Both ends of the main rope 14 are held by the car 11 and the counterweight 12, respectively.

[0029] The earthquake detection device 15 includes a first earthquake detector 19 and a second earthquake detector 20 separately.

[0030] The first earthquake detector 19 is, for example, an S-wave earthquake detector. The first earthquake detector 19 is installed in the machine room 7. The first earthquake detector 19 is configured to detect earthquakes above a first threshold value. The first threshold value is a predetermined threshold value for determining whether the elevator 3 can perform normal operation. The first threshold value is, for example, a value of acceleration corresponding to "low GAL" or "high GAL". Normal operation is a normal operation in which passengers of the elevator 3 can get on and off and move.

[0031] The second seismic detector 20 is, for example, a P+S wave seismic detector. The second seismic detector 20 is disposed in the bottom pit 6. The second seismic detector 20 is configured to be able to detect an earthquake above a second threshold value. The second threshold value is a predetermined threshold value for determining whether the elevator 3 can perform a diagnostic operation. The second threshold value is, for example, a value of acceleration corresponding to "diagnostic GAL". The second threshold value is set to a value larger than the first threshold value. The diagnostic operation is an operation of the elevator 3 for diagnosing whether it can return to normal operation.

[0032] The control panel 16 is disposed in the machine room 7. The control panel 16 includes a car control unit 161, a status management unit 162, an operation switch 163, a determination unit 164, and a transmission unit 165.

[0033] The car control unit 161 is connected to the car 11 in a manner capable of controlling the operation of the car 11. The operation of the car 11 includes the opening and closing of the car door 17 and the display of the car indicator 18. The car control unit 161 is connected to the traction machine 13 in a manner capable of controlling the operation of the traction machine 13. The operation of the traction machine 13 includes the start and stop of a motor (not shown). The car control unit 161 is configured to be able to receive status data from the car 11 and the traction machine 13. The status data is data indicating the operating state of the elevator 3.

[0034] The status management unit 162 is configured to be able to store the operability status of the normal operation and the diagnostic operation of the elevator 3 respectively. The status management unit 162 is connected to the first seismic detector 19 in a manner capable of sending a signal indicating an earthquake above the first threshold value. The status management unit 162 is connected to the second seismic detector 20 in a manner capable of sending a signal indicating an earthquake above the second threshold value. The status management unit 162 is connected to the car control unit 161 in a manner capable of communicating the operability status of the normal operation and the diagnostic operation of the elevator 3 respectively.

[0035] The operation switch 163 is a switch for switching the operation mode of the elevator 3. The operation modes include AUTO (automatic) mode and HAND (manual) mode. The AUTO mode is an automatic operation mode in normal operation and the like. The HAND mode is a manual operation mode in maintenance work and the like. The operation switch 163 is operated by maintenance personnel. The operation switch 163 is connected to the status management unit 162 in a manner capable of sending a signal indicating the operation of the maintenance personnel.

[0036] The determination unit 164 is connected to the status management unit 162 in a manner capable of reading the operability status of the normal operation and the diagnostic operation of the elevator 3 respectively. The determination unit 164 is configured to be able to determine whether to send a notification signal based on the read status.

[0037] The transmission unit 165 is connected to the determination unit 164 so as to be able to read the determination result. The transmission unit 165 is connected to the car control unit 161, the landing indicator 10, and the remote monitoring device 4 so as to be able to transmit a notification signal indicating a notification matter corresponding to the state read by the determination unit 164.

[0038] The remote monitoring device 4 is installed in, for example, a management room of the building 1. The remote monitoring device 4 is used for monitoring by a manager of the elevator 3, for example.

[0039] The monitoring center 21 is a base for remotely monitoring the elevator 3. The monitoring center 21 is connected to the remote monitoring device 4 via a communication line 22 so as to be communicable.

[0040] Next, the functions of the elevator system 2 will be described.

[0041] During the operation of the elevator 3, the car control unit 161 starts or stops the hoisting machine 13. The main ropes 14 are driven and moved by the started hoisting machine 13. The car 11 and the counterweight 12 follow the movement of the main ropes 14 and are raised and lowered.

[0042] When the state management unit 162 stores the normal operation as "possible" as the state of the elevator 3, the elevator 3 performs the normal operation. At this time, the operation mode of the elevator 3 is the AUTO mode.

[0043] In the normal operation of the elevator 3, the car 11 responds to the call from the user by ascending and descending in the hoistway 5. The car indicator 18 and the landing indicator 10 inform the user of the position of the car 11 by displaying the floor. The car 11 stops at the floor where the landing 8 is provided. The landing door 9 opens in conjunction with the car door 17. The user of the elevator 3 gets on the car 11 from the landing 8 or gets off the car 11 to the landing 8.

[0044] When an earthquake with a magnitude greater than or equal to the first threshold value occurs, the first earthquake detector 19 detects the earthquake. The first earthquake detector 19 sends a signal indicating the occurrence of the earthquake to the state management unit 162. The state management unit 162 switches the stored state of the normal operation of the elevator 3 to "No".

[0045] When the state management unit 162 stores “No” for the normal operation and “Yes” for the diagnostic operation as the state of the elevator 3 , the elevator 3 performs the diagnostic operation.

[0046] During the diagnostic operation of the elevator 3, the car control unit 161 controls the operations of the car 11, the traction machine 13, etc. according to pre-determined operation items. The operation items include, for example, the low-speed operation of the car 11, the normal-speed operation of the car 11, and the opening and closing of the car door 17. The car control unit 161 diagnoses whether the conditions of pre-determined diagnostic items are satisfied based on the status data received during the diagnostic operation. The diagnostic items include, for example, no interference of the main rope 14 and no abnormal noise during operation. The car control unit 161 determines whether the operation of the elevator 3 is abnormal based on the diagnostic results.

[0047] When the car control unit 161 determines that there is no abnormality, the status management unit 162 switches the stored normal operation status of the elevator 3 to "OK".

[0048] On the other hand, when the car control unit 161 determines that there is an abnormality, the status management unit 162 maintains the stored normal operation status of the elevator 3 as "NG". The determination unit 164 determines that a notification signal indicating the need for recovery by maintenance personnel should be sent as a notification item. The sending unit 165 sends a notification signal indicating this matter to the remote monitoring device 4. The remote monitoring device 4 sends a notification signal to the monitoring center 21.

[0049] When an earthquake of magnitude 2 or above occurs, the second earthquake detector 20 detects the earthquake. The second earthquake detector 20 sends a signal indicating the occurrence of the earthquake to the status management unit 162. The status management unit 162 switches the stored diagnostic operation status of the elevator 3 to "NG".

[0050] When the status management unit 162 stores that the normal operation is "NG" and the diagnostic operation is "NG" as the status of the elevator 3, the elevator 3 does not operate. The determination unit 164 determines that a notification signal indicating the need for recovery by maintenance personnel should be sent as a notification item. The sending unit 165 sends a notification signal indicating this matter to the remote monitoring device 4. The remote monitoring device 4 sends a notification signal to the monitoring center 21.

[0051] The maintenance personnel are requested to be dispatched through the notification of the remote monitoring device 4 or the monitoring center 21. The elevator 3 is restored by the maintenance personnel.

[0052] The restoration performed by the maintenance staff is carried out as follows. The maintenance staff confirms whether there are abnormalities such as damage to items inside the hoistway 5. The maintenance staff resets the first seismic detector 19 in the machine room 7. The maintenance staff, in the machine room 7, switches the operation mode of the elevator 3 from AUTO to HAND using the operation switch 163. At this time, the status management unit 162 switches the stored normal operation status of the elevator 3 to "available". The maintenance staff resets the second seismic detector 20 in the pit 6. At this time, the status management unit 162 switches the stored diagnostic operation status of the elevator 3 to "available". The maintenance staff confirms whether there are no abnormalities in the elevator 3 through a trial operation.

[0053] In this case, when the second seismic detector 20 is not reset due to a mistake of the maintenance staff or the like, the status management unit 162 stores the diagnostic operation status of the elevator 3 as "no".

[0054] When the status management unit 162 stores the normal operation as "available" and the diagnostic operation as "no" as the status of the elevator 3, the determination unit 164 determines to send a notification signal indicating that the reset of the second seismic detector 20 has been omitted as a notification item. The sending unit 165 sends a notification signal indicating this matter to the car indicator 18 through the car control unit 161. The sending unit 165 sends a notification signal indicating this matter to the landing indicators 10 of each of the plurality of landings 8.

[0055] The car indicator 18 notifies the maintenance staff who is performing the trial operation of the content indicated by the received notification signal. The car indicator 18 notifies by alternately displaying the floor display and the display indicating that the reset has been omitted. The display indicating that the reset has been omitted is, for example, the display of the character "H".

[0056] The landing indicator 10 notifies the maintenance staff who is performing the trial operation of the content indicated by the received notification signal. The landing indicator 10 notifies by alternately displaying the floor display and the display indicating that the reset has been omitted. The display indicating that the reset has been omitted is, for example, the display of the character "H".

[0057] Next, Figure 2 The operation of the control panel 16 will be described.

[0058] Figure 2 is a flowchart showing an example of the operation of the control panel according to Embodiment 1.

[0059] In step S1, the car control unit 161 determines whether the normal operation is "available". If the determination result is "no", the operation of the control panel 16 proceeds to step S2. If the determination result is "yes", the operation of the control panel 16 proceeds to step S6.

[0060] In step S2, the car control unit 161 determines whether the diagnostic operation is "permissible". If the determination result is "yes", the operation of the control panel 16 proceeds to step S3. If the determination result is "no", the operation of the control panel 16 proceeds to step S5.

[0061] In step S3, the car control unit 161 performs the diagnostic operation. Then, the operation of the control panel 16 proceeds to step S4.

[0062] In step S4, the car control unit 161 determines whether there is no abnormality during the diagnostic operation. If the determination result is "yes", the operation of the control panel 16 proceeds to step S1. If the determination result is "no", the operation of the control panel 16 proceeds to step S5.

[0063] In step S5, the state management unit 162 sets the state of the diagnostic operation to "no". Then, the transmitter 165 transmits a notification signal indicating that recovery by maintenance personnel is required. Then, the operation of the control panel 16 proceeds to step S1.

[0064] In step S6, the car control unit 161 performs the normal operation. Then, the operation of the control panel 16 proceeds to step S7.

[0065] In step S7, the car control unit 161 determines whether the diagnostic operation is "permissible". If the determination result is "yes", the operation of the control panel 16 proceeds to step S1. If the determination result is "no", the operation of the control panel 16 proceeds to step S8.

[0066] In step S8, the transmitter 165 transmits a notification signal indicating that the reset has been omitted. Then, the operation of the control panel 16 proceeds to step S1.

[0067] As described above, the elevator system 2 of Embodiment 1 includes a seismic detector 15, a landing indicator 10, a car indicator 18, and a control panel 16. The seismic detector 15 detects an earthquake equal to or greater than a first threshold value. The first threshold value is a threshold value for determining whether the elevator 3 can perform normal operation. The seismic detector 15 detects an earthquake equal to or greater than a second threshold value. The second threshold value is a threshold value for determining whether the elevator 3 can perform diagnostic operation. The landing indicator 10 notifies the maintenance personnel of the content indicated by the received notification signal. The car indicator 18 notifies the maintenance personnel of the content indicated by the received notification signal. The control panel 16 includes a status management unit 162 and a transmission unit 165. The status management unit 162 stores the status of whether the elevator 3 can perform normal operation. The status management unit 162 stores the status of whether the elevator 3 can perform diagnostic operation. When the seismic detector 15 detects an earthquake equal to or greater than the first threshold value, the status management unit 162 sets the normal operation to "no". When the seismic detector 15 detects an earthquake equal to or greater than the second threshold value, the status management unit 162 sets the diagnostic operation to "no". When the normal operation is "yes" and the diagnostic operation is "no", the transmission unit 165 sends a notification signal indicating that the reset has been omitted to the landing indicator 10 and the car indicator 18, respectively.

[0068] In the case where the reset of whether the diagnostic operation can be performed is omitted, the operating state of the elevator 3 becomes that the normal operation is "yes" and the diagnostic operation is "no". That is, the notification signal indicating that the reset has been omitted is a notification signal indicating that the normal operation is "yes" and the diagnostic operation is "no". In this case, the transmission unit 165 sends a notification signal indicating that the reset has been omitted to the landing indicator 10 and the car indicator 18, which are notification devices, respectively. The landing indicator 10 and the car indicator 18 respectively notify the maintenance personnel of the content of the notification signal. Thereby, in the restoration performed by the maintenance personnel, it is possible to prevent omission of the reset of whether the diagnostic operation can be performed.

[0069] In the case where the normal operation is performed in the state where the diagnostic operation is "no" due to omission of the reset, even when an earthquake equal to or greater than the first threshold value and less than the second threshold value occurs, the diagnostic operation is not automatically performed. Here, the elevator system 2 notifies the maintenance personnel that the reset has been omitted to prevent the situation where the normal operation is performed while maintaining the diagnostic operation as "no". Thereby, the elevator system 2 can improve the recovery rate of the diagnostic operation during an earthquake.

[0070] In addition, when the normal operation is "no", the transmission unit 165 does not send a notification signal to the landing indicator 10 and the car indicator 18.

[0071] When the normal operation is "No", the elevator 3 has not completed the recovery yet. Therefore, no reset is omitted. At this time, the sending unit 165 does not send a notification signal. That is, the sending unit 165 does not send a notification signal until a reset is omitted. Therefore, the sending unit 165 can send a notification signal at a timing that attracts the attention of the maintenance staff. Thus, during the recovery performed by the maintenance staff, it is possible to more reliably prevent the reset of the availability of the diagnostic operation from being omitted.

[0072] In addition, the earthquake detection device 15 separately includes a first earthquake detector 19 and a second earthquake detector 20. The first earthquake detector 19 detects an earthquake above a first threshold value. The second earthquake detector 20 detects an earthquake above a second threshold value.

[0073] The first earthquake sensor 19 and the second earthquake sensor 20 perform reset independently. Therefore, when resetting the first earthquake detector 19, it is possible that the reset of the second earthquake detector 20 is omitted. In this case, the elevator system 2 can also prevent the reset from being omitted.

[0074] In addition, the second earthquake detector 20 is arranged at a location separated from the first earthquake detector 19.

[0075] The first earthquake detector 19 and the second earthquake detector 20 are arranged in the machine room 7 and the pit 6 at locations separated from each other. Therefore, when resetting the first earthquake detector 19, it is possible that the reset of the second earthquake detector 20 is omitted. In this case, the elevator system 2 can also prevent the reset from being omitted.

[0076] Due to the natural vibration of the building 1, etc., there are cases where the building 1 swings with different accelerations at each location. Therefore, even when the first earthquake detector 19 does not detect an earthquake, it is possible that the second earthquake detector 20 detects an earthquake. At this time, the operation state of the elevator 3 is that the normal operation is "Yes" and the diagnostic operation is "No". In this case, even when an earthquake above the first threshold value and below the second threshold value occurs later, the diagnostic operation is not automatically executed. Here, the elevator system 2 prevents the normal operation from being performed in a state where the diagnostic operation is "No" by notifying the maintenance staff of the omission of the reset. Thus, the elevator system 2 can improve the recovery rate achieved by the diagnostic operation during an earthquake.

[0077] In addition, the second earthquake detector 20 is arranged at a location separated from the control panel 16.

[0078] When the operation switch 163 is operated to switch the operation mode of the elevator 3, it is possible that the reset of the second earthquake detector 20 is omitted. In this case, the elevator system 2 can also prevent the reset from being omitted.

[0079] In addition, a landing indicator 10 as a notification device is provided at a landing 8 of an elevator 3. A car indicator 18 as a notification device is provided in a car 11 of the elevator 3.

[0080] The landing 8 and the car 11 are places for maintenance personnel to confirm during the trial run of the recovery operation. Therefore, the maintenance personnel can confirm during the trial run whether any reset has been omitted.

[0081] In addition, when the state where normal operation is "enabled" and diagnostic operation is "disabled" continues for more than a predetermined time, the determination unit 164 may also determine to send a notification signal indicating that the state of omission of reset continues as a notification item. At this time, the sending unit 165 sends a notification signal indicating this matter to the remote monitoring device 4. The remote monitoring device 4 sends a notification signal to the monitoring center 21.

[0082] The landing indicator 10 and the car indicator 18 may also be a seven-segment display, a dot matrix display, a liquid crystal display, or the like. The landing indicator 10 and the car indicator 18 may also notify by simultaneously displaying the floor display and the display indicating omission of reset. The landing indicator 10 and the car indicator 18 may also notify by only displaying the display indicating omission of reset. The display indicating omission of reset may also be a display of a string such as "Reset omission has occurred".

[0083] The notification device may also be a speaker provided at the landing 8 or the car 11. At this time, the speaker notifies the maintenance personnel of the content indicated by the notification signal through a beeping sound or artificial voice, etc. The lighting provided at the landing 8 or the car 11 may also function as a notification device. At this time, the lighting notifies the maintenance personnel of the content indicated by the notification signal through blinking or the like.

[0084] The notification device may also be a portable terminal held by the maintenance personnel. The portable terminal is, for example, a smart phone. At this time, the portable terminal notifies the maintenance personnel of the content indicated by the notification signal through, for example, artificial voice, screen display, or vibration of a vibration device.

[0085] In addition, in order to improve the recovery rate during an earthquake by reliably implementing the diagnostic operation, the elevator 3 may also be configured not to perform normal operation even when the diagnostic operation is "disabled".

[0086] Next, Figure 3 An example of the hardware structure of the control panel 16 will be described.

[0087] Figure 3 FIG. is a diagram showing the hardware structure of the main part of the control panel according to Embodiment 1.

[0088] The various functions of the control panel 16 can be implemented by a processing circuit. The processing circuit includes at least one processor 16b and at least one memory 16c. The processing circuit includes a processor 16b and a memory 16c, or, as an alternative to them, may include at least one dedicated hardware 16a.

[0089] When the processing circuit includes a processor 16b and a memory 16c, the various functions of the control panel 16 are implemented by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. This program is stored in the memory 16c. The processor 16b implements the various functions of the control panel 16 by reading and executing the program stored in the memory 16c.

[0090] The processor 16b is also referred to as a CPU (Central Processing Unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The memory 16c is composed of, for example, non-volatile or volatile semiconductor memories such as RAM, ROM, flash memory, EPROM, and EEPROM, magnetic disks, floppy disks, optical disks, CDs (compact discs), minidisks, DVDs, etc.

[0091] When the processing circuit includes the dedicated hardware 16a, the processing circuit is implemented, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination of them.

[0092] The various functions of the control panel 16 can be implemented separately by the processing circuit. Alternatively, the various functions of the control panel 16 can also be implemented collectively by the processing circuit. For the various functions of the control panel 16, a part can be implemented by the dedicated hardware 16a and the other part can be implemented by software or firmware. In this way, the processing circuit implements the various functions of the control panel 16 through the hardware 16a, software, firmware, or a combination of them.
