Detailed Description
The modes for carrying out the invention are illustrated in accordance with the accompanying drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals. Repeated explanation of this part is appropriately simplified or omitted.
Embodiment mode 1
Fig. 1 is a configuration diagram of an elevator system according to embodiment 1.
In the elevator system of fig. 1, a hoistway 1 penetrates each floor of a building not shown. The machine room 2 is provided directly above the hoistway 1. The hoisting machine 3 is provided inside the machine room 2. The hoisting machine 3 has a sheave 4. The deflector wheel 5 is arranged inside the machine room 2. The deflector pulley 5 is connected with the sheave 4. The main ropes 6 are wound around the sheave 4 and the deflector sheave 5.
The car 7 is provided inside the hoistway 1. The car 7 is suspended on one side of the main rope 6. The counterweight 8 is provided inside the hoistway 1. The counterweight 8 is suspended from the other side of the main rope 6.
The car operating panel 9 is provided inside the car 7. The diagnostic device 10 is provided in the car 7. For example, the diagnostic device 10 is an accelerometer. The accelerometer is arranged to be able to measure the acceleration of the car 7. The diagnostic device 10 is, for example, a noise meter. The noise meter is provided to be able to measure the sound volume around the car 7. The diagnostic device 10 is, for example, a video camera. The camera is arranged to be able to photograph the periphery of the car 7.
The control device 11 is provided inside the machine room 2. The monitoring device 12 is provided inside the machine room 2. The monitoring device 12 is adjacent to the control device 11.
The information center device 13 is disposed at a position remote from the building provided with the elevator. For example, the information center device 13 is provided in a management company of an elevator system.
The control device 11 performs overall control of the elevator. For example, the control device 11 sets an operation mode of the elevator according to the situation. For example, when the operation mode of the elevator is the normal mode, when a call of the elevator is registered by the car operating panel 9 or the like, the control device 11 causes the car 7 to travel in response to the call.
The monitoring device 12 monitors the state of the elevator. For example, the monitoring device 12 monitors an abnormality of the elevator. For example, when an abnormality occurs in the elevator, the monitoring device 12 transmits a signal indicating the abnormality to the information center device 13.
For example, when the owner 14 of the elevator notices a problem such as a feeling of riding in the car 7 or an abnormal sound, the owner 14 performs a self-diagnosis request operation as a special operation on the car operating panel 9 or the owner terminal 15 which is a terminal of the owner 14 of the elevator. When the self-diagnosis request operation is performed, the car operation panel 9 or the owner terminal 15 transmits a self-diagnosis request signal. The control device 11 switches the operation mode of the elevator from the normal mode to the self-diagnosis mode in response to the self-diagnosis request signal.
When the operation mode of the elevator is changed to the self-diagnosis mode, the control device 11 causes the car 7 to travel to one of the lowermost floor and the uppermost floor. Then, the control device 11 moves the car 7 from one of the lowermost floor and the uppermost floor to the other of the lowermost floor and the uppermost floor while operating the diagnostic device 10. Then, the control device 11 transmits information indicating the measurement result of the diagnostic device 10 to the information center device 13 via the monitoring device 12.
In the management company, the manager uses the information center device 13 to transmit information showing the measurement result of the diagnosis device 10 to the portable terminal 17 of the operator 16 located near the elevator. For example, the manager uses the information center device 13 to transmit information showing the measurement result of the diagnosis device 10 to the portable terminal 17 of the operator 16 nearest to the elevator. The operator 16 checks the measurement result of the elevator diagnosis device 10 using the portable terminal 17, and examines the cause of the elevator problem. The operator 16 carries the replacement parts and the like necessary for eliminating the problem to the building in which the elevator is installed. Then, the worker 16 uses the replacement component or the like to solve the problem of the elevator.
Next, the operation of the control device 11 when the car operating panel 9 is operated to request a self-diagnosis will be described with reference to fig. 2.
Fig. 2 is a flowchart for explaining the operation of the control device when the car operating panel of the elevator system according to embodiment 1 performs a self-diagnosis request operation.
In step S1, the control device 11 determines whether or not the car operating panel 9 has received a self-diagnosis request operation. When it is determined in step S1 that the car operating panel 9 has not received a self-diagnosis request operation such as execution of a diagnosis operation, the control device 11 continues the operation of step S1. When it is determined in step S1 that the car operating panel 9 has received the self-diagnosis requesting operation, the control device 11 performs the operation of step S2.
In step S2, the control device 11 determines whether or not a load is generated inside the car 7.

When it is determined in step S2 that no load is generated in the car 7, the control device 11 performs the operation of step S4. In step S4, the control device 11 determines whether or not a call for an elevator is registered.
When it is determined in step S4 that an elevator call has been registered, the control device 11 performs the operation of step S3. In step S3, the control device 11 maintains the operation mode of the elevator in the normal mode. Then, the control device 11 performs the operation of step S1.
When it is determined in step S4 that a call for an elevator is not registered, the control device 11 performs the operation of step S5. In step S5, the control device 11 switches the operation mode of the elevator to the self-diagnosis mode. Then, the control device 11 performs the operation of step S6.
In step S6, the control device 11 moves the car 7 while operating the diagnostic device 10. Then, the control device 11 performs the operation of step S7. In step S7, the control device 11 transmits information indicating the measurement result of the diagnostic device 10 to the information center device 13. Then, the control device 11 performs the operation of step S1.
Next, the operation of the control device 11 when the owner terminal 15 performs the self-diagnosis request operation will be described with reference to fig. 3.
Fig. 3 is a flowchart for explaining the operation of the control device when the owner terminal of the elevator system according to embodiment 1 performs a self-diagnosis request operation.
In step S11, the control device 11 determines whether a self-diagnosis request signal is received from the owner terminal 15. If it is determined in step S11 that the control device 11 has not received the self-diagnosis request signal from the owner terminal 15, the control device 11 continues the operation of step S11. When it is determined in step S11 that the control device 11 has received the self-diagnosis request signal from the owner terminal 15, the control device 11 performs the operation of step S12.
In step S12, the control device 11 determines whether or not a signal indicating whether or not a load is generated inside the car 7 is received from the owner terminal 15. If it is determined in step S12 that the control device 11 has not received a signal indicating whether or not a load is generated inside the car 7 from the owner terminal 15, the control device 11 continues the operation of step S12.
When it is determined in step S12 that the control device 11 has received a signal indicating whether or not a load is generated in the car 7 from the owner terminal 15, the control device 11 performs the operation of step S13. In step S13, the control device 11 determines whether or not the signal indicates that a load is generated inside the car 7.
When it is determined in step S13 that the signal indicates that a load is generated inside the car 7, the control device 11 performs the operation of step S14. In step S14, the control device 11 maintains the operation mode of the elevator in the normal mode. Then, the control device 11 performs the operation of step S11.
If it is determined in step S13 that the signal indicates that no load is generated inside the car 7, the control device 11 performs the operation of step S15. In step S15, the control device 11 determines whether or not a signal indicating whether or not a call for an elevator is registered is received from the owner terminal 15.
When it is determined in step S15 that the control device 11 has not received a signal indicating whether or not a call for an elevator has been registered from the owner terminal 15, the control device 11 continues the operation of step S15.
When it is determined in step S15 that the control device 11 has received a signal indicating whether or not a call for an elevator has been registered from the owner terminal 15, the control device 11 performs the operation of step S16. In step S16, the control device 11 determines whether or not the signal is a signal indicating that a call for an elevator is registered.
When it is determined in step S16 that the signal is a signal indicating that an elevator call has been registered, the control device 11 performs the operation of step S14. In step S14, the control device 11 maintains the operation mode of the elevator in the normal mode. Then, the control device 11 performs the operation of step S11.
When it is determined in step S16 that the signal indicates that an elevator call is not registered, the control device 11 performs the operation of step S17. In step S17, the control device 11 switches the operation mode of the elevator to the self-diagnosis mode. Then, the control device 11 performs the operation of step S18.
In step S18, the control device 11 moves the car 7 while operating the diagnostic device 10. Then, the control device 11 performs the operation of step S19. In step S19, the control device 11 transmits information indicating the measurement result of the diagnostic device 10 to the information center device 13. Then, the control device 11 performs the operation of step S11.
According to embodiment 1 described above, when the operation mode of the elevator is the normal mode, the control device 11 switches the operation mode of the elevator to the self-diagnosis mode in response to the self-diagnosis request signal from the outside. At this time, the control device 11 operates the diagnostic device 10 and transmits a signal indicating the diagnostic result of the diagnostic device 10 in the self-diagnosis mode to the outside. Therefore, the state of the elevator can be notified to the outside such as the operator 16 as soon as possible.
Then, the operator 16 confirms the measurement result of the diagnostic apparatus 10 using the portable terminal 17. Therefore, the cause of the problem of the elevator can be studied before going to the building where the elevator is provided. As a result, the time for solving the problem can be significantly shortened.
Then, the control device 11 operates the diagnostic device 10 while moving the car 7. Therefore, the problematic part of the elevator can be estimated more accurately.
For example, the diagnostic device 10 measures acceleration or sound volume. Therefore, the cause of the elevator problem can be estimated more accurately.
When a load is generated in the car 7 or when a call of the elevator is registered, the control device 11 does not switch the operation mode of the elevator to the self-diagnosis mode. Therefore, the self-diagnosis of the elevator can be prevented from being performed in a state where the user is using the elevator.
In addition, the owner terminal 15 may be a general terminal such as a personal computer, a smart phone, or the like. In this case, the owner terminal 15 may be provided with application software for self-diagnosis of the elevator and may transmit and receive signals to and from the control device 11.
Next, an example of the control device 11 will be described with reference to fig. 4.
Fig. 4 is a hardware configuration diagram of a control device of an elevator system according to embodiment 1.
The respective functions of the control device 11 can be realized by a processing circuit. For example, the processing circuitry has at least one processor 18a and at least one memory 18 b. For example, the processing circuit has at least one dedicated hardware 19.
In the case of a processing circuit having at least one processor 18a and at least one memory 18b, the functions of the control device 11 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. At least one of the software and firmware is stored in the at least one memory 18 b. The at least one processor 18a realizes the respective functions of the control device 11 by reading out and executing programs stored in the at least one memory 18 b. The at least one processor 18a 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 18b 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 the processing circuit has at least one dedicated hardware 19, 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, each function of the control device 11 is realized by each processing circuit. For example, the respective functions of the control device 11 are collectively realized by a processing circuit.
The functions of the control device 11 may be partly implemented by dedicated hardware 19 and partly implemented by software or firmware. For example, the function of switching the operation mode of the elevator is realized by a processing circuit as the dedicated hardware 19, and the function other than the function of switching the operation mode of the elevator is realized by reading out and executing a program stored in the at least one memory 18b by the at least one processor 18 a.
In this way, the processing circuitry can implement the functions of the control device 11 by hardware 19, software, firmware, or a combination thereof.
