Detailed Description
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 part is appropriately simplified or omitted.
Fig. 1 is a configuration diagram of an elevator system to which a battery diagnosis device for an elevator in embodiment 1 of the present invention is applied.
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 traction machine 4 is provided inside the machine room 3. The hoisting machine 3 is provided with a sheave 4. The diverting pulley 5 is arranged inside the machine room 3. The diverting pulley 5 is adjacent to the sheave 4. The main ropes 6 are wound around the sheave 4 and the return sheave 5.
The car 7 is disposed inside the hoistway 1. The car 7 is suspended on one side of the main rope 6. The counterweight 8 is disposed inside the hoistway 1. A counterweight 8 is suspended on the other side of the main rope 6.
The control device 9 is arranged inside the machine room 2. The monitoring device 10 is provided inside the machine room 2. The monitoring device 10 is electrically connected to the control device 9. The battery 11 is disposed inside the machine room 2. For example, the battery 11 may be provided inside the monitoring device 10. The battery 11 is electrically connected to the monitoring device 10. The battery 11 is provided as a backup power source for the monitoring apparatus 10. For example, the battery 11 is a nickel cadmium battery. The battery 11 is, for example, a nickel-hydrogen battery.
The information center apparatus 12 is disposed at a position away from a building where an elevator is disposed. The information center device 12 is installed in an elevator management company, for example.
The control device 9 performs overall control of the elevator. For example, when the operation mode of the elevator is the normal mode, the control device 9 moves the car 7 in response to a call of the elevator.
The monitoring device 10 monitors the state of the elevator. For example, when an abnormality of the elevator occurs when the operation mode of the elevator is the normal mode, the monitoring device 10 transmits information indicating the abnormality to the information center device 12. For example, when the power supply to the monitoring apparatus 10 is cut off due to a power failure or the like, the monitoring apparatus 10 transmits information indicating that the power supply is cut off to the information center apparatus 12. At this time, the monitoring device 10 operates using the electric power from the battery 11.
Next, the monitoring device 10 will be described with reference to fig. 2.
Fig. 2 is a block diagram of a monitoring device as an elevator battery diagnosis device according to embodiment 1.
As shown in fig. 2, the monitoring device 10 includes a switching unit 13, a monitoring unit 14, a measuring unit 15, a storage unit 16, a determination unit 17, and a control unit 18.
The switching unit 13 is provided to be able to switch the mode of the monitoring apparatus 10. Specifically, the switching unit 13 switches the mode of the monitoring device 10 between the normal mode and the battery degradation determination mode.
The monitoring unit 14 is provided to be able to change a monitoring target according to the mode of the monitoring apparatus 10. For example, when the mode of the monitoring device 10 is the normal mode, the monitoring unit 14 monitors the state of the elevator. For example, when the mode of the monitoring device 10 is the degradation determination mode, the monitoring unit 14 monitors the state of the battery 11.
The measurement unit 15 is provided to be able to measure the characteristics of the battery 11. For example, the measurement unit 15 applies an ac voltage having a frequency of 0Hz to several MHz to the battery 11 to measure the impedance of the battery 11.
The storage unit 16 is provided to be capable of storing information indicating the measurement result of the measurement unit 15. For example, when the measuring unit 15 measures the characteristics of the battery 11, the storage unit 16 stores the information of the measurement date and time of the characteristics in association with the information of the characteristics.
The determination unit 17 is provided to be able to determine the state of the battery 11 based on the measurement result of the measurement unit 15. For example, the determination unit 17 determines the state of the battery 11 based on the result of comparison between the measurement result of the measurement unit 15 and the reference stored in the storage unit 16. The determination unit 17 determines that the battery 11 is in the degraded state, for example, when determining that the battery 11 is expected to be degraded when 3 months have elapsed from the measurement date and time.
The control unit 18 is provided to be able to control the operation of the switching unit 13 and the operation of the measuring unit 15. For example, the control unit 18 switches the mode of the monitoring device 10 from the normal mode to the battery deterioration diagnosis mode by operating the switching unit 13 at a predetermined measurement time. For example, when the determination unit 17 determines that the battery 11 is not in the degraded state when the mode of the monitoring device 10 is the battery degradation determination mode, the actual load test of the monitoring device 10 is performed using the power from the battery 11.
In the actual load test, the monitoring device 10 operates using the electric power from the battery 11 in a manner simulating that the power supply to the monitoring device 10 is cut off due to a power failure or the like. In this state, the monitoring unit 14 transmits information indicating that the power supply is cut off to the information center apparatus 12 via a public line or the like. At this time, the monitoring unit 14 transmits information that can be distinguished from when the mode is the normal mode. The information center apparatus 12 transmits a confirmation signal indicating that the information indicating that the power supply is cut off is received. The monitoring unit 14 receives the confirmation signal.
Next, an outline of the operation of the work condition monitoring device 9 will be described with reference to fig. 3.
Fig. 3 is a flowchart for explaining an outline of an operation of a monitoring device as a battery diagnosis device for an elevator according to embodiment 1.
In step S1, the monitoring device 10 determines whether or not a condition for switching the operation mode from the normal mode to the battery degradation diagnosis mode is satisfied.
If it is determined in step S1 that the condition for switching the operation mode from the normal mode to the battery degradation diagnosis mode is not satisfied, the monitoring device 10 performs the operation of step S2. In step S2, the monitoring device 10 monitors the state of the elevator. Then, the monitoring device 10 performs the operation of step S1.
When it is determined in step S1 that the condition for switching the operation mode from the normal mode to the battery degradation diagnosis mode is satisfied, the monitoring device 10 performs the operation of step S3. The conditions for switching the modes include, for example, a preset measurement time, and the monitoring device 10 detecting or notifying the abnormality of the elevator or the power supply. In step S3, the monitoring device 10 switches the operation mode from the normal mode to the battery deterioration diagnosis mode, and then determines whether or not the battery 11 is in a deteriorated state.
If it is determined in step S3 that battery 11 is not in a deteriorated state, monitoring device 10 performs the operation of step S4. In step S4, the monitoring device 10 performs an actual load test of the monitoring device 10 using the electric power from the battery 11. Then, the monitoring device 10 performs the operation of step S1.
When it is determined in step S3 that battery 11 is in a deteriorated state, monitoring device 10 performs the operation of step S5. In step S5, the monitoring device 10 transmits information indicating that the battery 11 is in a degraded state to the outside. Then, the monitoring device 10 performs the operation of step S1.
According to embodiment 1 described above, the actual load test of the monitoring device 10 is performed when the battery 11 is not in a deteriorated state. Therefore, useless attempts to monitor the actual load test of the apparatus 10 can be prevented.
When the battery 11 is in the degraded state, a signal indicating that the battery 11 is in the degraded state is transmitted to the outside. Therefore, it is possible to replace the battery 11 at an appropriate timing suitable for the life. As a result, the maintenance work time of the battery 11 can be shortened. Further, the cost for replacing the battery 11 can be reduced.
In addition, the state of the battery 11 is determined based on the characteristics of the battery 11. Therefore, the deterioration state of the battery 11 can be determined more accurately.
The discharge curve when a load is applied to the battery 11 may be used as the characteristic of the battery 11. In this case, the deterioration state of the battery 11 can be determined more accurately.
Further, information on the date and time of measurement of the characteristics of the battery 11 is stored in association with the information on the characteristics. Therefore, the change over time in the characteristics of the battery 11 can be grasped. As a result, the life and replacement timing of the battery 11 can be estimated.
Further, information on the date and time of measurement of the characteristics of the battery 11, information on the characteristics, and information on the region where the battery 11 is installed may be stored in association with each other. In this case, the change over time in the characteristics of the battery 11 can be analyzed for each similar region. As a result, the reference for determining the state of the battery 11 can be set according to the environment in which the battery 11 is installed.
The criterion for determining the state of the battery 11 may be updated based on the characteristics measured by the measurement unit 15. For example, when the impedance of the battery 11 is measured, a curve of the impedance with respect to the change with time is used as a reference. If the reference is updated based on the measurement result of the measurement unit 15, the deterioration state of the battery 11 can be determined more accurately.
The battery diagnosis device having the functions of the switching unit 13, the monitoring unit 14, the measuring unit 15, the storage unit 16, the determining unit 17, and the control unit 18 may be provided separately from the monitoring device 10. In this case, too, it is possible to prevent useless attempts to actually test the load of the monitoring apparatus 10.
In addition, the function of the switching unit 13 may be realized by using a physical switch. In this case, when the worker performs the maintenance operation, the operation mode of the monitoring device 10 can be switched between the normal mode and the battery degradation diagnosis mode.
The operation mode of the monitoring device 10 may be switched based on the diagnosis command information from the information center device 12. In this case, the deterioration state of the battery 11 can be determined finely as needed.
The monitoring device 10 according to embodiment 1 may be applied to an elevator without the machine room 2. In this case, too, it is possible to prevent useless attempts to actually test the load of the monitoring apparatus 10.
Next, an example of a main part of the monitoring device 10 will be described with reference to fig. 4.
Fig. 4 is a hardware configuration diagram of a main part of a monitoring device of an elevator battery diagnosis device according to embodiment 1.

For example, the processing circuit is provided with at least one processor 19a and at least one memory 19 b. For example, the processing circuitry is provided with at least one dedicated hardware 20.
In the case where the processing circuit includes at least one processor 19a and at least one memory 19b, the functions of the main portion of the monitoring apparatus 10 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 19 b. The at least one processor 19a realizes the respective functions of the monitoring apparatus 10 by reading out and executing programs stored in the at least one memory 19 b. The at least one processor 19a is also referred to as a cpu (central Processing unit), a central Processing unit, a Processing unit, an arithmetic unit, a microprocessor, a microcomputer, and a DSP. For example, the at least one Memory 19b 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 CD (compact Disk), a mini Disk (mini disc), a DVD (Digital Versatile Disk), or the like.
In the case where the processing circuit includes at least one dedicated hardware 20, 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, the respective functions of the main part of the monitoring apparatus 10 may be realized by the processing circuit, respectively. For example, the functions of the main part of the monitoring apparatus 10 may be realized by the processing circuit in a unified manner.
The functions of the monitoring apparatus 10 may be partially implemented by dedicated hardware 20, and the other parts may be implemented by software or firmware. For example, the function of the determination unit 17 may be realized by a processing circuit as dedicated hardware 20, and the function other than the function of the determination unit 17 may be realized by at least one processor 19a reading and executing a program stored in at least one memory 19 b.
In this way, the processing circuit implements the functions of the main portion of the monitoring apparatus 10 using hardware 20, software, firmware, or a combination thereof.
Although not shown, the functions of the main portion of the control device 9 can be realized by a processing circuit equivalent to the processing circuit that realizes the functions of the main portion of the monitoring device 10.
