Detailed Description
The invention is described with reference to the accompanying drawings. Duplicate descriptions are appropriately simplified or omitted. In the drawings, the same reference numerals denote the same or equivalent parts.
Fig. 1 is a diagram showing an example of an elevator apparatus according to embodiment 1. The elevator apparatus includes, for example, a car 1 and a counterweight 2. The car 1 moves up and down in the hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The car 1 and the counterweight 2 are suspended in the hoistway 3 by the main rope 4.
The main ropes 4 are wound around a drive sheave 6 of a hoisting machine 5. The car 1 moves in accordance with the rotation of the drive sheave 6. The control device 7 controls the rotation and stop of the drive sheave 6. That is, the car 1 is controlled by the control device 7.
The monitoring device 8 is connected to the control device 7 and communicates with the control device 7. The monitoring device 8 is a device for communicating with the outside via the network 9. For example, the monitoring apparatus 8 is connected to a remote information center 10 via a network 9. In an elevator apparatus, for example, a diagnostic operation is periodically performed. The monitoring device 8 transmits data acquired during the diagnostic operation to the information center 10 via the network 9.
The monitoring device 8 is supplied with electric power from, for example, a commercial power supply (not shown). The elevator apparatus further includes a secondary battery 11 as a backup power supply for the monitoring device 8. That is, electric power can be supplied from the secondary battery 11 to the monitoring device 8. For example, when the power supply to the monitoring device 8 is turned off due to a power failure, that is, when the power is no longer supplied from the commercial power supply to the monitoring device 8, the power from the secondary battery 11 is supplied to the monitoring device 8. The secondary battery 11 may be incorporated in the monitoring device 8.
In the example shown in fig. 1, the elevator apparatus further includes a thermometer 12 for measuring the temperature of the secondary battery 11. For example, the thermometer 12 is directly provided to the secondary battery 11. The thermometer 12 may be disposed inside a case that houses the secondary battery 11. Information on the temperature measured by the thermometer 12 is input to the monitoring device 8.
Fig. 2 is a diagram showing an example of functions of the monitoring device 8. As shown in fig. 2, the monitoring device 8 includes, for example, a storage unit 20, a charging unit 21, a selection unit 22, a temperature detection unit 23, a cycle calculation unit 24, a time detection unit 25, a lifetime calculation unit 26, a determination unit 27, and a communication unit 28. The charging unit 21 charges the secondary battery 11. While the monitoring device 8 is supplied with electric power from the commercial power supply, the secondary battery 11 is in a fully charged state in principle.
The storage unit 20 stores information necessary for control. For example, the storage unit 20 stores the 1 st and 2 nd arithmetic expressions. The 1 st and 2 nd arithmetic expressions are expressions for calculating the replacement cycle of the secondary battery 11. The 1 st operation formula is shown as [ equation 1]. The 2 nd operation formula is shown as [ equation 2].
[ numerical formula 1]
[ numerical formula 2]
Wherein,
Q 1 、Q 2 : capacity retention rate (%)
T: absolute temperature (K) of the environment of use
N p : working time (h)
A p 、-E R /R、A cyc 、-E cyc R: a constant.
The constant indicating the deterioration rate is determined as a constant in which the relationship between the deterioration coefficient and the temperature follows arrhenius' law, for example.
Fig. 3 is a diagram for explaining the cause of deterioration of the secondary battery. In most elevator installations, they are used in principle without a power supply interruption. In such an elevator apparatus, the power supply to the monitoring device is not disconnected in principle. Only trickle charging is performed for the secondary battery.
The deterioration of the secondary battery provided in the elevator apparatus is caused by the operating time. The 1 st operation expression is an expression for calculating the replacement cycle of the secondary battery based on the deterioration due to the operating time. In the 1 st operation formula, a value corresponding to deterioration due to an operating time is calculated, and the value is subtracted from 1 to calculate a ratio when the initial capacity of the secondary battery is 100% as a capacity maintenance rate Q 1 . The curve A shown in FIG. 3 shows the operating time N p Capacity retention Q calculated for 1 st expression of variable 1 Examples of (3).
On the other hand, in some elevator apparatuses, power supply is periodically or aperiodically cut off. In such an elevator apparatus, the power supply to the monitoring device is also turned off periodically or aperiodically. When the power supply to the monitoring device is turned off, power is supplied from the secondary battery to the monitoring device. Further, when the power supply to the monitoring device is turned on thereafter, the secondary battery is charged. In other words, in such an elevator apparatus, the secondary battery is repeatedly charged and discharged.
The deterioration of the secondary battery provided in such an elevator apparatus is caused by the operation time and charging/discharging. The 2 nd operation expression is an expression for calculating the replacement cycle of the secondary battery based on the deterioration due to the operating time and the deterioration due to charge and discharge. The 2 nd operation expression shows that deterioration due to operating time progresses independently of deterioration due to charge and discharge, and the sum of these corresponds to the capacity deterioration of the secondary battery. That is, in the 2 nd operation formula, the score is calculatedThe value corresponding to the deterioration due to the operation time and the value corresponding to the deterioration due to the charge and discharge are calculated independently of each other, and the sum of these values is subtracted from 1 to calculate the ratio when the initial capacity of the secondary battery is 100%, as the capacity maintenance rate Q 2 . The curve B shown in FIG. 3 shows the operating time N p Capacity retention Q calculated for the 2 nd expression of the variable 2 Examples of (3). In fig. 3, a curve a and a curve B are obtained by substituting a specific value into the temperature T.
In the 1 st and 2 nd operational expressions, A p Is a constant representing the deterioration due to the operating time. Likewise, -E R the/R is a constant representing the energy of degradation due to the operating time. A. The cyc Is a constant indicating deterioration due to charge and discharge. -E cyc The term,/R, is a constant representing the energy of deterioration due to charge and discharge.
Hereinafter, the functions of the elevator apparatus will be described with reference to fig. 4. Fig. 4 is a flowchart showing an operation example of the elevator apparatus according to embodiment 1.
In the example shown in the present embodiment, the storage unit 20 stores in advance on/off information of the power supply to the monitoring device 8. As described above, there are an elevator apparatus in which the power supply to the monitoring apparatus is basically disconnected and an elevator apparatus in which the power supply to the monitoring apparatus is periodically or aperiodically disconnected. The storage unit 20 stores information indicating which type of monitoring device 8 provided in the elevator apparatus corresponds to as on/off information. For example, if the power supply of the monitoring apparatus 8 is not turned off in principle, the information C1 is stored in the storage unit 20 as on/off information in advance. If the power of the monitoring device 8 is likely to be turned off, the information C2 is stored in the storage unit 20 as on/off information.
In the monitoring device 8, the selection unit 22 acquires the on/off information stored in the storage unit 20 (S101). The selection unit 22 selects one of the 1 st or 2 nd arithmetic expressions based on the on/off information acquired in S101 (S102). For example, if the information C1 is stored in the storage unit 20, the selection unit 22 selects the 1 st operation expression in S102. If the information C2 is stored in the storage unit 20, the selection unit 22 selects the 2 nd arithmetic expression in S102.
Next, the temperature detector 23 detects the temperature of the secondary battery 11 (S103). As described above, the information of the temperature measured by the thermometer 12 is input to the monitoring device 8. The temperature detector 23 detects the temperature of the secondary battery 11 based on the information input from the thermometer 12.
Next, the cycle calculator 24 calculates a replacement cycle of the secondary battery 11 (S104). The cycle calculator 24 performs the calculation in S104 based on the calculation formula selected by the selector 22 in S102 and the temperature detected by the temperature detector 23 in S103. For example, if the selection unit 22 selects the 1 st arithmetic expression in S102, the cycle calculation unit 24 calculates the replacement cycle of the secondary battery 11 using the 1 st arithmetic expression.
For example, the capacity maintenance rate Q at which the lifetime of the secondary battery 11 is determined to expire is set in advance 1 The value of (c). In FIG. 3, the capacity maintenance rate Q 1 The value of (d) is noted as the threshold. For example, the threshold value is set according to a capacity that allows the monitoring device 8 to report to the information center 10 for a predetermined time or longer at the time of power failure. The predetermined time is, for example, 30 minutes, and the threshold value is set to, for example, 27%. Capacity maintenance rate Q for determining expiration of life of secondary battery 11 1 The value of (c) is not limited to the above example.
By the capacity maintenance rate Q that will determine the expiration of the life of the secondary battery 11 1 By substituting the value of (1) and the temperature T of the environment into the formula 1, the operating time N as the lifetime in the environment can be calculated p I.e. the replacement cycle. The temperature T can be obtained from the temperature detected by the temperature detector 23. For example, the temperature detected by the temperature detector 23 is [ ° c]The temperature T can be obtained by adding 273.15 to the average value of (2).
The same applies to the case where the selection unit 22 selects the 2 nd operation expression in S102. That is, if the selection unit 22 selects the 2 nd arithmetic expression in S102, the cycle calculation unit 24 calculates the replacement cycle of the secondary battery 11 using the 2 nd arithmetic expression. For example, in advanceThe capacity maintenance rate Q for determining the expiration of the life of the secondary battery 11 is set first 2 Value (threshold value) of (c). For example, the threshold value is set to 27%. By the capacity maintenance rate Q that will determine the expiration of the life of the secondary battery 11 2 The operating time N as the life under the operating environment can be calculated by substituting the value of (2) and the temperature T of the operating environment into the arithmetic expression p I.e. the replacement cycle.
Next, the time detector 25 detects the operating time of the secondary battery 11 (S105). For example, the time detector 25 detects the elapsed time from the mounting of the secondary battery 11 to the present as the operating time.
Next, the life calculation unit 26 calculates the remaining life of the secondary battery 11 (S106). The life calculation unit 26 performs the calculation of S106 based on the replacement cycle of the secondary battery 11 calculated by the cycle calculation unit 24 and the actual operating time of the secondary battery 11 detected by the time detection unit 25. For example, the life calculation unit 26 can obtain the remaining life of the secondary battery 11 by subtracting the operating time detected in S105 from the replacement cycle calculated in S104.
Next, the determination unit 27 determines whether or not the remaining life of the secondary battery 11 calculated by the life calculation unit 26 is lower than a reference value (S107). If it is determined as yes in S107, the communication unit 28 transmits a signal indicating that the replacement timing of the secondary battery 11 is approaching to the information center 10 (S108). If it is determined as no in S107, the monitoring device 8 ends the process.
In the example shown in the present embodiment, a signal corresponding to the remaining life of the secondary battery 11 can be transmitted from the communication unit 28 based on the replacement cycle calculated by the cycle calculation unit 24 and the operating time detected by the time detection unit 25. For example, a plurality of signals corresponding to the remaining life of the secondary battery 11 may be transmitted from the communication unit 28 to the information center 10 by setting the reference value to be compared with the remaining life to a plurality of levels. For example, if the 1 st reference value is set to 90 days, the 1 st signal indicating replacement can be transmitted to the information center 103 months before the lifetime of the secondary battery 11 is determined to have expired. Further, if the 2 nd reference value is set to 30 days, the 2 nd signal indicating replacement can be transmitted to the information center 102 months after the 1 st signal is transmitted.
In the example shown in the present embodiment, the selection unit 22 selects one of the 1 st or 2 nd arithmetic expressions based on the on/off information stored in the storage unit 20. Then, the replacement cycle of the secondary battery 11 is calculated based on the operation formula selected by the selection unit 22. In the example shown in the present embodiment, the replacement cycle of the secondary battery 11 can be known more accurately. Further, inventory management of the secondary battery 11 becomes easy, and the burden of replacement work by a maintenance worker can be reduced.
Fig. 5 is a diagram showing an example of another function of the monitoring device 8. Fig. 6 is a flowchart showing another operation example of the elevator apparatus. In the example shown in fig. 5, the monitoring device 8 includes a count detection unit 29 and a registration unit 30 in addition to the functions shown in fig. 2.
The number-of-times detecting unit 29 detects the number of times of turning on/off the power supply to the monitoring device 8 (S201). The registration unit 30 registers the on/off information of the power supply to the monitoring device 8 in the storage unit 20 based on the number of times of on/off detected by the number-of-times detection unit 29 (S202). For example, if the number of times of on/off detected by the number-of-times detecting unit 29 is 0 times, the registering unit 30 registers the information C1 as on/off information in the storage unit 20. If the number of times of on/off detection by the number-of-times detection unit 29 is 1 or more, the registration unit 30 registers the information C2 as on/off information in the storage unit 20.
As another example, if the number of times of on/off detected by the number-of-times detecting unit 29 in the last year is equal to or less than a specific number of times, the registering unit 30 may register the information C1 as on/off information in the storage unit 20. In this case, when the number of times of on/off detected by the number-of-times detecting unit 29 in the last year exceeds the above-described specific number of times, the registering unit 30 registers the information C2 as on/off information in the storage unit 20.
Fig. 7 is a diagram showing an example of a life curve corresponding to the type of the secondary battery. Some elevator apparatuses include a Ni — Cd battery as a backup power source for a monitoring device. As another example, a Ni-MH battery can be used as a backup power supply for the monitoring device.
The curve A1 shown in fig. 7 is an example of a curve represented by the 1 st expression in the case where a Ni — Cd battery is used as the secondary battery 11. The curve B1 is an example of a curve represented by the 2 nd arithmetic expression in the case where a Ni — Cd battery is used as the secondary battery 11. TH1 represents a threshold corresponding to the Ni — Cd battery. Similarly, curve A2 is an example of a curve represented by the expression 1 when a Ni-MH battery is used as the secondary battery 11. Curve B2 is an example of a curve represented by the formula 2 in the case where a Ni-MH battery is used as the secondary battery 11. TH2 represents a threshold value corresponding to the Ni-MH battery.
For example, a plurality of sets of 1 st and 2 nd arithmetic expressions corresponding to the types of the secondary batteries 11 may be stored in the storage unit 20 in advance. In this case, the storage unit 20 stores information indicating the type of the secondary battery 11 used. In S102, the selection unit 22 may select 1 operation expression from the plurality of operation expressions stored in the storage unit 20 based on the on/off information stored in the storage unit 20 and the information indicating the type of the secondary battery 11. For example, when the storage unit 20 stores information indicating a Ni-MH battery as information indicating the type of the secondary battery 11 and information C1 as on/off information, the selection unit 22 selects the 1 st expression corresponding to the curve A2 in S102.
In embodiment 1, an example in which a plurality of arithmetic expressions for calculating the replacement cycle of the secondary battery 11 are stored in the storage unit 20 is described. In the present embodiment, an example in which 1 operational expression is stored in the storage unit 20 will be described. In this embodiment, a difference from the example disclosed in embodiment 1 will be described in detail.
Fig. 8 is a diagram showing an example of functions of the monitoring device 8. In the example shown in the present embodiment, the monitoring device 8 includes, for example, a storage unit 20, a charging unit 21, a temperature detection unit 23, a cycle calculation unit 24, a time detection unit 25, a lifetime calculation unit 26, a determination unit 27, and a communication unit 28.
The storage unit 20 stores the 3 rd operation formula. The 3 rd arithmetic expression is an expression for calculating the replacement cycle of the secondary battery 11. The 3 rd operation formula is shown as [ equation 3].
[ numerical formula 3]
Wherein Q is 3 The capacity maintenance rate (%) is D, and the number of times of turning on/off the power supply to the monitoring device 8 is D. For example, the number of on/off times is represented by the number of times the power supply is switched from on to off during a year. The number of on/off times may also be the number of times the power supply is switched from off to on during a year. Note that the 1 st expression shown in embodiment 1 corresponds to a case where the value of D is 0 in the 3 rd expression. The 2 nd expression corresponds to the case where the value of D is 365 in the 3 rd expression.
Hereinafter, the functions of the elevator apparatus will be described with reference to fig. 9. Fig. 9 is a flowchart showing an operation example of an elevator apparatus according to embodiment 2.
In the example shown in the present embodiment, the number of times of turning on/off the power supply to the monitoring device 8 is stored in advance as on/off information in the storage unit 20. For example, if it is predicted that the power supply to the monitoring apparatus 8 is turned off once a day, information showing "365 times" is stored as on/off information in the storage unit 20. If it is predicted that the power supply to the monitoring apparatus 8 is turned off once a week, information showing "52 times" is stored as on/off information in the storage section 20.
In the monitoring device 8, the temperature detection unit 23 detects the temperature of the secondary battery 11 (S301). The processing shown in S301 is the same as the processing shown in S103.
Next, the cycle calculating unit 24 acquires the on/off information stored in the storage unit 20 (S302). Further, the cycle calculator 24 calculates a replacement cycle of the secondary battery 11 (S303). The cycle calculator 24 calculates S303 using the 3 rd calculation expression based on the on/off information acquired in S302 and the temperature detected by the temperature detector 23 in S301.
Similarly to the example shown in embodiment 1, the capacity maintenance rate Q for determining the expiration of the life of the secondary battery 11 is set in advance 3 The value of (c). By the capacity maintenance rate Q that will determine the expiration of the life of the secondary battery 11 3 By substituting the value of (3), the temperature T of the environment and the number of times of ON/OFF (ON/OFF information) into the formula (3), the operating time N as the lifetime in the environment can be calculated p I.e. the replacement cycle.
The processing shown in S304 to S307 of fig. 9 is the same as the processing shown in S105 to S108 of fig. 4. For example, the time detector 25 detects the operating time of the secondary battery 11 (S304). Next, the life calculation unit 26 calculates the remaining life of the secondary battery 11 (S305). For example, the life calculation unit 26 performs the calculation of S305 based on the replacement cycle of the secondary battery 11 calculated by the cycle calculation unit 24 and the actual operating time of the secondary battery 11 detected by the time detection unit 25.
Next, the determination unit 27 determines whether or not the remaining life of the secondary battery 11 calculated by the life calculation unit 26 is lower than a reference value (S306). If it is determined as yes in S306, the communication unit 28 transmits a signal indicating that the replacement timing of the secondary battery 11 is approaching to the information center 10 (S307). If it is determined as no in S306, the monitoring device 8 ends the process.
In the example shown in the present embodiment, a signal corresponding to the remaining life of the secondary battery 11 can be transmitted from the communication unit 28 based on the replacement cycle calculated by the cycle calculation unit 24 and the operating time detected by the time detection unit 25. The reference value to be compared with the remaining life may be set to a plurality of levels, and a plurality of signals corresponding to the remaining life of the secondary battery 11 may be transmitted from the communication unit 28 to the information center 10.
In the example shown in embodiment 2, the cycle calculation unit 24 also calculates the replacement cycle of the secondary battery 11 based on the on/off information stored in the storage unit 20. Therefore, the replacement cycle of the secondary battery 11 can be known more accurately. Further, inventory management of the secondary battery 11 becomes easy, and the burden of replacement work by a maintenance worker can be reduced.
Fig. 10 is a diagram showing an example of another function of the monitoring device 8. In the example shown in fig. 10, the monitoring device 8 includes a count detection unit 29 and a registration unit 30 in addition to the functions shown in fig. 8. The elevator apparatus performs the same operation as the operation shown in fig. 6, for example.
The number-of-times detecting unit 29 detects the number of times of turning on/off the power supply to the monitoring device 8 (S201). The registration unit 30 registers the on/off information of the power supply to the monitoring device 8 in the storage unit 20 based on the number of times of on/off detected by the number-of-times detection unit 29 (S202). For example, the registration unit 30 registers the number of times of on/off detected by the number-of-times detection unit 29 during the last year in the storage unit 20 as on/off information. In this case, in S302, the cycle calculator 24 acquires the on/off information registered in the storage unit 20 by the registration unit 30.
As described above, the 1 st expression shown in embodiment 1 corresponds to the case where the value of D is 0 in the 3 rd expression. The 2 nd expression corresponds to the case where the value of D is 365 in the 3 rd expression. In the example shown in embodiment 1, in order to grasp the replacement cycle of the secondary battery 11 more accurately, 3 or more working expressions obtained by substituting different values for D in the 3 rd working expression may be stored in the storage unit 20 in advance.
For example, when 3 arithmetic expressions are used, in addition to the above-described 1 st and 2 nd arithmetic expressions, the 4 th arithmetic expression in which the value of D in the 3 rd arithmetic expression is 183 (≈ 365/2) may be stored in the storage unit 20 in advance. When 4 arithmetic expressions are used, in addition to the 1 st and 2 nd arithmetic expressions described above, a 5 th arithmetic expression in which the value of D in the 3 rd arithmetic expression is 122 (≈ 365/3) and a 6 th arithmetic expression in which the value of D in the 3 rd arithmetic expression is 244 may be stored in the storage unit 20 in advance.
For example, the registration unit 30 registers the number of times of on/off detected by the number-of-times detection unit 29 during the last year in the storage unit 20 as on/off information. Then, the selection unit 22 selects the optimum 1 expression from the plurality of expressions stored in the storage unit 20 based on the on/off information stored in the storage unit 20. For example, if the storage unit 20 stores the 4 arithmetic expressions described above, and if information indicating "250 times" is stored as the on/off information in the storage unit 20, the selection unit 22 selects the 6 th arithmetic expression in S102.
In the present embodiment, each of the parts indicated by reference numerals 20 to 30 shows a function of the monitoring device 8. Fig. 11 is a diagram showing an example of hardware resources of the monitoring apparatus 8. The monitoring device 8 includes, as hardware resources, a processing circuit 40 including a processor 41 and a memory 42, for example. The function of the storage unit 20 is realized by the memory 42. The monitoring device 8 realizes the functions of the respective sections shown by reference numerals 21 to 30 by executing the program stored in the memory 42 by the processor 41.
Fig. 12 is a diagram showing another example of the hardware resources of the monitoring apparatus 8. In the example shown in fig. 12, the monitoring device 8 includes a processing circuit 40 including, for example, a processor 41, a memory 42, and dedicated hardware 43. Fig. 12 shows an example in which a part of the functions of the monitoring apparatus 8 is realized by dedicated hardware 43. All the functions of the monitoring apparatus 8 may be realized by the dedicated hardware 43.
