The car 6 is disposed inside the hoistway 1. The car 6 is supported by one side of the main rope 5. The counterweight 7 is disposed inside the hoistway 1. The counterweight 7 is supported on the other side of the main rope 5.
A plurality of landing doors 8 are provided at each doorway of the plurality of landings 3. The car door 9 is provided at an entrance of the car 6.
The disaster prevention storage device 10 is provided inside the car 6. The disaster prevention storage device 10 stores disaster prevention emergency products, not shown.
The control device 11 is installed in the machine room 2. The control device 11 is provided to be able to control the elevator as a whole.
The monitoring device 12 is installed in the machine room 2. The monitoring device 12 is provided to be able to monitor the state of the elevator based on information from the control device 11.
The information center device 13 is installed in a place remote from a building in which an elevator is installed. For example, the information center device 13 is installed in an information center of an elevator maintenance company. The information center device 13 is provided so as to be able to grasp the state of the elevator based on the information from the monitoring device 12.
Next, the control of locking/unlocking the disaster prevention storage device 10 will be described with reference to fig. 2.
Fig. 2 is a block diagram of a main part of an elevator system according to embodiment 1.
As shown in fig. 2, the door 10a is provided to be openable and closable with respect to the opening of the disaster prevention storage device 10. The electronic lock 10b is provided to the door 10 a. The electronic lock 10b is provided to be able to maintain the door 10a in a closed state in the locked state and to release the door 10a from the closed state in the unlocked state. In normal operation, the electronic lock 10b is maintained in the locked state.
The monitoring device 12 includes an abnormality detection unit 12a, a user detection unit 12b, a lock/unlock control unit 12c, and a notification control unit 12 d.
The abnormality detection unit 12a detects an abnormality of the elevator. For example, the abnormality detection unit 12a detects an abnormality of the elevator based on a detection signal from an unillustrated seismic sensor. For example, the abnormality detector 12a detects an abnormality of the elevator based on a detection signal from a fire sensor, not shown.
The user detection unit 12b detects a user inside the car 6. For example, the user detection unit 12b detects a user inside the car 6 from an image of a camera, not shown, provided in the car 6. For example, the user detection unit 12b detects a user inside the car 6 based on a detection value of a weighing device, not shown, provided in the car 6. For example, the user detection unit 12b detects the user inside the car 6 based on the determination signal from the information center device 13 in a state where the monitoring device 12 transmits a trapped signal indicating that the user inside the car 6 is trapped to the information center device 13 and an unillustrated extension telephone button provided in the car 6 is pressed to establish a communication line between the inside of the car 6 and the information center.
When the abnormality of the elevator is detected by the abnormality detection unit 12a, the locking/unlocking control unit 12c changes the disaster prevention storage device 10 from the locked state to the unlocked state. Specifically, the lock/unlock control unit 12c sets the electronic lock 10b to the unlocked state. Then, when the user detection unit 12b does not detect a user inside the car 6, the locking/unlocking control unit 12c changes the disaster prevention storage device 10 from the unlocked state to the locked state. Specifically, the lock/unlock control unit 12c locks the electronic lock 10 b.
When the locking/unlocking control unit 12c changes the disaster prevention storage device 10 from the locked state to the unlocked state, the notification control unit 12d causes a not-shown notification device provided in the car 6 to notify that the disaster prevention storage device 10 is in the unlocked state. For example, the notification control unit 12d causes the display device to notify that the disaster prevention storage device 10 is in the unlocked state by displaying. For example, the notification control unit 12d notifies the disaster prevention storage device 10 of the unlocked state by sound from a speaker.
Next, an outline of the operation of the monitoring device 12 will be described with reference to fig. 3.
Fig. 3 is a flowchart for explaining an outline of an operation of the monitoring device of the elevator system in embodiment 1.
In step S1, the monitoring device 12 determines whether an abnormality of the elevator is detected. If it is determined in step S1 that an abnormality in the elevator has not been detected, the monitoring device 12 performs the operation of step S1. If it is determined in step S1 that an abnormality in the elevator has been detected, the monitoring device 12 performs the operation of step S2.
In step S2, the monitoring device 12 changes the disaster prevention storage device 10 from the locked state to the unlocked state. Then, the monitoring device 12 performs the operation of step S3. In step S3, the monitoring device 12 causes the notification device to notify that the disaster prevention storage device 10 is in the unlocked state. Then, the monitoring device 12 performs the operation of step S4. In step S4, the monitoring device 12 determines whether or not a user inside the car 6 is detected.
If it is determined in step S4 that the user inside the car 6 is detected, the monitoring device 12 performs the operation of step S4. If it is determined in step S4 that the user inside the car 6 is not detected, the monitoring device 12 performs the operation of step S5. In step S5, the monitoring device 12 changes the disaster prevention storage device 10 from the unlocked state to the locked state. Then, the monitoring device 12 ends the operation.
According to embodiment 1 described above, when a user inside the car 6 is not detected at the time of an elevator abnormality, the disaster prevention storage device 10 is locked. Therefore, unnecessary opening of the door 10a of the disaster prevention storage device 10 can be suppressed. As a result, the disaster prevention emergency products stored in the disaster prevention storage device 10 can be prevented from scattering inside the car 6.
For example, the monitoring device 12 detects a user inside the car 6 from an image of a camera. For example, the monitoring device 12 detects a user inside the car 6 based on a detection value of a weighing device, not shown, provided in the car 6. For example, in a state where the telephone-line button is pressed to establish a communication line between the inside of the car 6 and the information center, the monitoring device 12 detects a user inside the car 6 based on a determination signal from the information center device 13. Therefore, unnecessary opening of the door 10a of the disaster prevention storage device 10 can be more reliably suppressed.
Further, the monitoring device 12 causes the notification device to notify that the disaster prevention storage device 10 is in the unlocked state. Therefore, the user can be prompted to use the disaster prevention emergency article.
In addition, two electronic locks 10b may be provided to the door 10 a. In this case, when an abnormality of the elevator is detected, one of the two electronic locks 10b may be set to the unlocked state, and then, if a user inside the car 6 is detected, the other of the two electronic locks 10b may be set to the unlocked state. In this case, too, unnecessary opening of the door 10a of the disaster prevention storage device 10 can be more reliably suppressed.
In addition, the monitoring device 12 may maintain the disaster prevention storage device 10 in the locked state until the user inside the car 6 is detected in the case of an elevator abnormality, and may change the disaster prevention storage device 10 from the locked state to the unlocked state after the user inside the car 6 is detected. In this case, too, unnecessary opening of the door 10a of the disaster prevention storage device 10 can be suppressed.
Next, an example of the monitoring device 12 will be described with reference to fig. 4.
Fig. 4 is a hardware configuration diagram of a monitoring device of an elevator system in embodiment 1.
The functions of the monitoring device 12 can be realized by a processing circuit. For example, the processing circuit is provided with at least one processor 100a and at least one memory 100 b. For example, the processing circuit is provided with at least one dedicated hardware 200.
In the case of a processing circuit having at least one processor 100a and at least one memory 100b, the functions of the monitoring device 12 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 software and firmware is stored in the at least one memory 100 b. The at least one processor 100a realizes the functions of the monitoring apparatus 12 by reading out and executing programs stored in the at least one memory 100 b. The at least one processor 100a is also referred to as a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. For example, the at least one Memory 100b is a nonvolatile or volatile semiconductor Memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash Memory, an EP ROM (Erasable Programmable Read Only Memory), an E EPROM (Electrically Erasable Programmable Read Only Memory), a compact disc, a mini disc, a DVD (Digital Versatile disc), or the like.
In the case where the processing Circuit includes at least one dedicated hardware 200, the processing Circuit is realized by, for example, 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 thereof. For example, each function of the monitoring device 12 is realized by a processing circuit. For example, the functions of the monitoring device 12 are collectively realized by a processing circuit.
The functions of the monitoring device 12 may be partly implemented by dedicated hardware 200 and partly implemented by software or firmware. For example, the functions of the lock/unlock control unit 12c may be realized by a processing circuit as dedicated hardware 200, and the functions other than the functions of the lock/unlock control unit 12c may be realized by at least one processor 100a reading and executing a program stored in at least one memory 100 b.
In this way, the processing circuitry implements the functions of the monitoring device 12 via hardware 200, software, firmware, or a combination thereof.
The functions of the control device 11 are also realized by the same processing circuit as the processing circuit that realizes the functions of the monitoring device 12. The functions of the information center apparatus 13 are also realized by the same processing circuits as those of the monitoring apparatus 12.
In addition, a part or all of the functions of the monitoring device 12 may be realized by other devices. For example, the function of the user detection unit 12b may be realized by the control device 11.
