Description

  The present invention relates to, for example, a group management control device, a group management control method, and a group management control system that perform group management control in accordance with the remaining power of a power storage device.

  Conventional cars have been supplied with power through a power cord in the hoistway and a tail cord connecting the car, and operated the equipment in the car (car lighting, air conditioner, etc.). However, when the car provides a long-haul service, the weight of the tail cord affects the movement of the car. For this reason, an elevator apparatus has been provided which eliminates the tail cord or reduces the power supply function to the car through the tail cord. In such an elevator apparatus, the equipment in the car is operated by the electric power supplied from the power storage device installed in the car. When the remaining amount of power in the power storage device decreases, the car stops on the power supply floor in the hoistway, and non-contact power supply is performed from the power supply device installed on the power supply floor to the power storage device.

  However, in an elevator system that performs group management control of a plurality of elevator devices, the remaining power of the power storage device differs for each unit. For this reason, unless appropriate group management control is performed, the remaining power of the power storage device is insufficient during the service, and the service cannot be provided to the user. A power storage device with a low remaining power must be fed with priority.

  Therefore, a technique disclosed in Patent Document 1 is known as a non-contact power supply system that has a plurality of units and supplies power to a battery installed in a car of each unit in a non-contact manner. Patent Document 1 states that “a value obtained by adding preliminary power set in advance to the required power predicted by the power prediction unit is compared with the battery power detected by the battery remaining power detection unit, and based on the comparison result. To control the allocation of additional calls to each unit ".

JP 2013-71804 A

  The non-contact power feeding system described in Patent Document 1 prohibits assignment of a new destination floor call to the relevant unit when the remaining power of the power storage device is lower than the required power amount predicted in advance from the call. Then, the car is moved to the power supply floor. In this system, the machine control device checks the remaining power of the power storage device and controls the operation of the car.

  When the devices and power storage devices in the car deteriorate, the power consumption of the devices increases, and the actual power consumption tends to increase more than the predicted power consumption predicted in advance. For this reason, conventionally, the predicted power consumption is predicted to be larger than the actual power consumption. For example, Patent Document 1 describes that standby power set in advance is added to the predicted required power.

  However, if the predicted power consumption is large, it is determined that the remaining amount of power is insufficient even if the power storage device has a sufficient amount of remaining power. Therefore, the number of times of power supply by moving the car to the power supply floor increases. For this reason, the operation rate (for example, service providing time × 100 / (service providing time + time required for power supply)) of the elevator apparatus in a predetermined period (for example, one month) is reduced.

  The present invention has been made in view of such a situation, and an object of the present invention is to dispatch a car while suppressing the influence of power feeding to a power storage device.

  The group management control device according to the present invention is configured such that the destination floor call is registered in the destination floor call registration device, whereby the unit control device that controls the operation of a plurality of cars moving on the hoistway for each unit from each unit. Used in the car based on the operation history of the car represented by the operation data received in the car and the remaining power of the power storage device represented by the remaining power data of the power storage device installed in the car The predicted power consumption predicted from the required power and the predicted power remaining amount of the power storage device are obtained, and the unit that is assigned the destination floor call is evaluated by comparing the predicted power consumption and the predicted power remaining amount for each unit. A comparison unit that calculates the assigned evaluation value for each unit, assigns a destination floor call to a unit that has a higher assigned evaluation value than the assigned evaluation value set for other units, and places the car on the unit controller Priority group And a performing Unit operation control unit of the operation control by the management.

According to the present invention, for example, even if there is an individual difference in the power remaining amount of the power storage device for each unit, when the destination floor call is registered, the predicted power consumption and the predicted power remaining amount are accurately determined for each unit. Therefore, the group evaluation control for giving priority to the car of the desired car is possible. As described above, since the remaining power of the power storage device is predicted every time a new destination floor call is generated, it is not necessary to predict the predicted power consumption excessively. And the frequency | count of electric power feeding to an electrical storage apparatus can be reduced, and an operation rate improves.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same function or configuration are denoted by the same reference numerals, and redundant description is omitted.

[First Embodiment]
First, the group management control system according to the first embodiment of the present invention will be described.
FIG. 1 is an explanatory diagram illustrating a schematic configuration example of a group management control system 1 according to the first embodiment.

  The group management control system 1 operates the three cars 2A to 2C of No. A to C, the power feeding devices 21A to 21C provided on a predetermined floor of the hoistway 20, and the operations of the three cars 2A to 2C. The number control devices 6A to 6C to be controlled, the group management control device 7, and the destination floor call registration device 8 are provided. The group management control device 7 is connected to machine control devices 6A to 6C and a destination floor call registration device 8.

First, the configuration of the car A of the A-unit will be described.
The car 2A can be raised and lowered in the ascending or descending direction in the hoistway 20 while balancing with a counterweight (not shown). The operation of the car 2A is controlled by the number control device 6A. The car 2A is equipped with a power receiving device 3A, a power storage device 4A, and a remaining power measuring device 5A. In FIG. 1, the car 2A is stopped so that the power receiving device 3A faces the power feeding device 21A. At this time, the power receiving device 3A is supplied with power from the power feeding device 21A and charges the power storage device 4A.

Here, the definition of the words and phrases related to the power storage devices 4A to 4C will be described with reference to FIG.
FIG. 2 is an explanatory diagram illustrating an example of the storage capacity of the power storage device 4A.
In the present embodiment, the storage capacity of power storage device 4A represents the amount of power that can be stored. The power storage device 4A is not deteriorated, and the current power storage capacity of the power storage device 4A is 100%, which is the same as the initial value of the new power storage device 4A. That is, when the power storage device 4A is fully charged, the remaining amount of power is the same as the power storage capacity. Then, by receiving power supply from the power storage device 4A, devices used in the car 2A (destination floor button lamp, air conditioner, in-car lighting, doors, etc.) operate, and power is consumed by the devices. For example, if a destination floor call from the 1st floor to the 10th floor is registered and the car 2A is operated, “power consumption by opening and closing the door on the 1st floor”, “movement of 9 floors from the 1st floor to the 10th floor” The total amount of “power consumption for the device” and “power consumption by opening and closing the door on the 10th floor” is the power consumption of the device. After the power storage device 4A is fully charged, the car 2A is operated, and the device consumes the power supplied from the power storage device 4A, so that the remaining power of the power storage device 4A is reduced by the amount of power consumed by the device.

  For this reason, the comparison part 11 estimates the power consumption of the apparatus in the case of assigning a destination floor call to No. A machine before the operation of the car 2A. This predicted power consumption of the device is referred to as predicted power consumption. Further, the comparison unit 11 predicts a value obtained by subtracting the predicted power consumption from the current power remaining amount as the predicted power remaining amount. If the predicted power remaining amount is positive, the car 2A can be operated, but if the predicted power remaining amount is negative, the car 2A cannot be operated, and the power storage device 4A needs to be charged. Even if the predicted remaining power level is positive, if the charging threshold value th1 (for example, 20% of the storage capacity) or less, the remaining power level may be insufficient during the operation, so the power storage device 4A is charged. Necessary. If the power storage device 4A needs to be charged, the number machine operation control unit 12 controls the operation so that the car 2A is moved to the power supply floor and power is supplied from the power supply device 21A to the power storage device 4A through the power reception device 3A.

Returning again to the description of FIG.
The remaining power measurement device 5A measures the remaining power of the power storage device 4A, and transmits remaining power data to the machine control device 6A. The remaining power measurement device 5A also measures the time until the power storage device 4A is fully charged, and can include the measurement time in the remaining power data and transmit it to the machine control device 6A. The remaining power measuring device 5A may be installed in the machine control device 6A.

  The unit control device 6A includes an operation data transmission unit 9A and a remaining power data transmission unit 10A. The number control device 6A controls the operation of the car 2A that is number A.

  The operation data transmission unit 9A includes operation data of the car 2A (for example, information on the position of the car 2A, door open / closed state, door sensor ON / OFF, power consumption of the air conditioner, etc.). Send to. The timing at which the operation data transmitting unit 9A transmits the operation data to the group management control device 7 is, for example, when the destination floor call is registered in the destination floor call registration device 8, and the group control control device 7 to the machine control device 6A. The transmission of operation data is started by a transmission instruction given to.

  The remaining power data transmitter 10 </ b> A transmits the remaining power data of the power storage device 4 </ b> A received from the remaining power measuring device 5 </ b> A to the group management control device 7. The timing at which the remaining power data transmission unit 10A transmits the remaining power data to the group management control device 7 is, for example, when the destination floor call is registered in the destination floor call registration device 8, and from the group management control device 7. Transmission of the remaining power data is started by a transmission instruction given to the machine control device 6A.

  In addition, about the B machine and C machine provided in the same hoistway 20 as the A machine, it is comprised similarly to the A machine. The car B 2B has a power receiving device 3B, a power storage device 4B, and a remaining power measuring device 5B. The car C of the C car 2C has a power receiving device 3C, a power storage device 4C, and a remaining power measurement. A device 5C is mounted. The power receiving device 3B of Unit B charges the power storage device 4B with the power supplied from the power supply device 21B, and the power receiving device 3C of the Unit C charges the power storage device 4C with the power supplied from the power supply device 21C.

  As with the Unit A control device 6A, the Unit B control device 6B includes an operation data transmission unit 9B and a remaining power data transmission unit 10B, and the Unit C control device 6C includes an operation data transmission unit 9C. And a remaining power data transmission unit 10C. When the destination floor call is registered in the destination floor call registration device 8, the operation data transmission unit 9B transmits the operation data of the car 2B to the group management control device 7, and the remaining electric power data transmission unit 10B The remaining power data of the power storage device 4B is transmitted to the group management control device 7. Similarly, when the destination floor call is registered in the destination floor call registration device 8, the operation data transmission unit 9C transmits the operation data of the car 2C to the group management control device 7, and the remaining power data transmission unit 10C Then, the remaining power data of the power storage device 4C is transmitted to the group management control device 7.

The group management control device 7 includes a comparison unit 11, a number machine operation control unit 12, and a power consumption table T1.
The power consumption table T <b> 1 is a table that stores the operation data for each unit transmitted from the unit control devices 6 </ b> A to 6 </ b> C and the remaining power of the power storage device represented by the remaining power data of the power storage device. In the power consumption table T1, the operation history represented by the operation data for each unit and the required power of the device are stored. For example, in the power consumption table T1, changes in the remaining amount of power when the car 2A moves from the first floor to the tenth floor are stored as an operation history representing a collection of operation data managed in history. A detailed configuration example of the power consumption table T1 is shown in FIG.

  The comparison unit 11 registers the destination floor call in the destination floor call registration device 8 so that the cars 2A to 2C are based on the operation history of the cars 2A to 2C and the remaining power of the power storage devices 4A to 4C. The predicted consumption power amount predicted from the required power of the equipment used in the process and the predicted power remaining amount of the power storage devices 4A to 4C are obtained. The operation histories of the cars 2A to 2C are represented by the operation data of the cars 2A to 2C received for each car from the car control devices 6A to 6C. The remaining electric power of power storage devices 4A to 4C is represented by the remaining power data of power storage devices 4A to 4C. Further, the comparison unit 11 refers to the power consumption table T1 and predicts the power consumption necessary for moving the cars 2A to 2C based on the operation history and the change in the remaining power for each unit. Then, the estimated power remaining amount of the power storage devices 4A to 4C is obtained, and the allocation evaluation value for evaluating the unit to which the destination floor call is allocated by comparing the predicted consumption power amount and the predicted power remaining amount for each unit is determined for each unit. To calculate. And the comparison part 11 sets a high allocation evaluation value with respect to the number machine with much consumption prediction electric energy of an apparatus by deterioration of an apparatus progressing. The assigned evaluation value is a value calculated based on, for example, the operation status of the cars 2A to 2C, the progress of deterioration of the equipment, etc., and if the assigned evaluation value is high, the destination floor call is preferentially assigned, Be dispatched.

  The number machine operation control unit 12 assigns a destination floor call to a number machine having an assigned evaluation value higher than an assigned evaluation value set for another number machine. For example, when the destination floor call is assigned to No. A, the No. operation control unit 12 performs the operation control by group management in which the car 2A of the No. car assigned the destination floor call is preferentially allocated to the No. control device 6A. . However, since the predicted power remaining amount of the power storage device 4B is smaller than that of the power storage device 4A, for example, the allocation evaluation value of Unit A is calculated as “3” and the allocation evaluation value of Unit B is calculated as “2”. If the elevator car 2B of Unit B is near the landing floor where the destination floor call is registered, the assigned evaluation value of Unit B may be set to “4”. Thus, the allocation evaluation value is a relative value used for allocating a destination floor call to each unit. In this case, the numbering machine operation control unit 12 performs control to give priority to the car 2B.

  In addition, the unit operation control unit 12 performs operation control to give priority to the car of the unit having a large amount of predicted power consumption of the device due to the deterioration of the device. In this case, the comparison unit 11 sets a high allocation evaluation value for a unit having a large amount of predicted power consumption of the device. For example, the allocation evaluation value of Unit B may be set to “4” even when the predicted power consumption of the equipment used in the Car 2B of the Unit B is large. Also in this case, the car operation control unit 12 controls the car 2B to give priority to dispatch. For this reason, it becomes easy to dispatch a car provided with a device with a large amount of predicted power consumption due to deterioration.

  Note that if the predicted remaining power level of the power storage device is equal to or less than the charging threshold th1, the comparison unit 11 sets a lower allocation evaluation value (eg, “1”). For this reason, the unit operation control unit 12 moves the car of the unit whose allocation evaluation value is low and the predicted remaining power is equal to or less than the charging threshold th1 to the power supply floor where the power supply device is installed, and the hoistway Control is performed to supply power to the power storage device in a non-contact manner from the power supply device provided at 20.

  For example, the unit operation control unit 12 allocates a destination floor call to the unit having the highest allocation evaluation value. Here, when the passenger registers the destination floor call by operating the destination floor call registration device 8 installed on the landing floor, the number machine operation control unit 12 acquires the call registration data from the destination floor call registration device 8. When the unit operation control unit 12 acquires the call registration data, the unit operation control unit 12 allocates a destination floor call to one of the units based on the allocation evaluation value of each unit. And the number machine operation control part 12 performs control which preferentially dispatches the car from which waiting time becomes the shortest among the cars 2A-2C which perform allocation with the present electric power remaining amount.

  For example, it is assumed that the car 2A is preferentially dispatched. In this case, the number machine operation control unit 12 outputs a number machine assignment signal to the number machine control device 6A of the number A machine to which the destination floor call is assigned. The number controller 6A to which the number assignment signal is input performs control to move the car 2A to the boarding floor where the destination floor call is registered in accordance with the assigned destination floor call.

  Thus, when the unit operation control unit 12 assigns a destination floor call to a unit, the comparison unit 11 uses the operation history and the remaining power for each unit in advance, and the current predicted power consumption. The allocation evaluation value calculated by comparing with the remaining power is used. For this reason, it is possible to perform operation control for preferentially allocating the cars to be allocated based on the accurate remaining power of the power storage devices 4A to 4C having individual differences.

Next, a hardware configuration of the computer C configuring each device of the group management control system 1 will be described.
FIG. 3 is a block diagram illustrating a hardware configuration example of the computer C. For example, the machine control devices 6A to 6C and the group management control device 7 are configured by a computer C.

  The computer C is hardware used as a so-called computer. The computer C includes a CPU (Central Processing Unit) C1, a ROM (Read Only Memory) C2, and a RAM (Random Access Memory) C3 connected to the bus C4. Furthermore, the computer C includes a nonvolatile storage C5 and a network interface C6.

  The CPU C1 reads out the program code of software that implements each function according to the present embodiment from the ROM C2, and executes it. In the RAM C3, variables, parameters and the like generated during the arithmetic processing are temporarily written. The CPU C1 realizes the functions of the operation data transmitters 9A to 9C, the remaining power data transmitters 10A to 10C of the unit control devices 6A to 6C, and the comparison unit 11 and the unit operation control unit 12 of the group management controller 7. Is done.

  As the nonvolatile storage C5, for example, an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory, or the like is used. It is done. In the nonvolatile storage C5, in addition to the OS (Operating System) and various parameters, a program for causing the computer C to function is recorded. The ROM C2 and the non-volatile storage C5 record programs and data necessary for the operation of the CPU C1, and are computer-readable non-transitory recording media storing programs executed by the computer C. Used as an example. For this reason, this program is permanently stored in the ROM C2 and the non-volatile storage C5. The power consumption table T1 is stored in the RAM C3 or the non-volatile storage C5 provided in the group management control device 7, and can be appropriately read out by the comparison unit 11.

  For example, a network interface card (NIC) or the like is used as the network interface C6, and various types of data can be transmitted and received between devices via a LAN (local area network) connected to a terminal, a dedicated line, or the like. is there. For example, the number control devices 6A to 6C receive the remaining power data from the cars 2A to 2C through the network interface C6, and transmit the remaining power data and operation data to the group management control device 7. Then, the unit assignment signal is received from the group management control device 7 through the network interface C6.

  FIG. 4 is an explanatory diagram of the power consumption table T1. In the power consumption table T1, changes in operation history and remaining power are managed for each unit.

  Comparing section 11 requires the required power for each unit determined from the amount of power (power consumption) consumed by power storage devices 4A to 4C when the cars 2A to 2C are operated based on changes in the operation history and the remaining power. Are stored in the power consumption table T1. However, in the power consumption table T1 shown in FIG. 4, it is assumed that the necessary power based on the operation history of the Unit A and Unit B and the change in the remaining amount of power is stored.

  For example, the data No. of the power consumption table T1. 1, data no. 2 represents a past performance value indicating a change in the remaining amount of power in the assigned destination floor call. Data No. 3 represents a current predicted value indicating a change in the remaining electric power for each unit predicted for a newly registered destination floor call.

  Looking at Unit A, data no. 1 indicates that the remaining electric power of the power storage device 4A changes from 100% to 90% due to the operation of the car 2A from the first floor to the tenth floor. Data No. 2 also shows that the remaining amount of power of the power storage device 4A changes by 10%.

  Looking at Unit B, data no. 1 indicates that the remaining electric power of the power storage device 4B changes from 100% to 80% due to the operation of the car 2B from the first floor to the tenth floor. Data No. 2 also shows that the remaining amount of power of the power storage device 4B changes by 20%. For this reason, since the equipment used in the car 2B is more deteriorated than the equipment used in the car 2A, the power consumption of the equipment is large and the remaining power of the power storage device 4B is low. It can be seen that it decreases faster than the power storage device 4A. Although not shown, the operation history of Unit C and the change in the remaining power are also stored in the power consumption table T1.

  The comparison unit 11 refers to the power consumption table T1, calculates the power required when the cars 2A and 2B move a predetermined floor, based on the operation history and the change in the remaining power, and uses the power consumption table T1. To store. For example, in Unit A, the required power for the car 2A to operate from the first floor to the tenth floor is 10% of the full charge (100%) of the power storage device 4A. In Unit B, the necessary power for the car 2B to operate from the first floor to the tenth floor is 20% of the full charge (100%) of the power storage device 4B. And the comparison part 11 calculates | requires consumption prediction electric energy and prediction electric power residual amount for every unit, and calculates | requires allocation evaluation value.

  The unit operation control unit 12 allocates a destination floor call to a unit having a high allocation evaluation value. For example, data No. As shown in FIG. 3, the power remaining amount of each power storage device when a destination floor call that operates from the first floor to the 20th floor is assigned is considered. In Unit A, the current remaining power level is 50%, and the predicted remaining power level after service completion changes to 30%, whereas in Unit B, the current remaining power level is 50%, after service completion. It is shown that the predicted power remaining amount changes to 10%. For example, if allocation is impossible when the predicted remaining power level after service completion is 20% or less, the car 2B of Unit B is operated from the first floor to the 20th floor with a remaining power level of 50%. I can't. In this case, since the comparison evaluation unit 11 sets the allocation evaluation value of Unit B to the lowest value, the unit operation control unit 12 excludes the car 2B from the allocation target of the destination floor call. And the No. machine operation control part 12 performs control which moves the passenger car 2B with a low allocation evaluation value to an electric power feeding floor, and supplies electric power to the electrical storage apparatus 4B.

  For the allocation of destination floor calls, priority is given to, for example, a machine that can handle a new destination floor call with a remaining amount of power and that has the shortest waiting time for passengers who have registered the destination floor call. For example, since the assigned evaluation value of the machine waiting on the floor close to the landing floor where the destination floor call is registered becomes high, the destination floor call is assigned to this machine.

FIG. 5 is a flowchart illustrating an example of the number assignment process.
First, the destination floor call registration device 8 determines whether a new destination floor call is registered by the passenger (S1). If a new destination floor call is not registered (NO in S1), this process is terminated, and this process is started again after a predetermined time. When a new destination floor call is registered (YES in S1), the destination floor call is transmitted to the group management control device 7.

  Next, the comparison unit 11 initializes a variable n representing the number machine with “1” (S2). In addition, “1” of the variable n represents Unit A, “2” represents Unit B, and “3” represents Unit C. When “1” is set to the variable n in step S2, the subsequent processing is processing related to the No. A machine.

  Next, the comparison unit 11 calculates the power consumption (predicted power consumption) of the car 2n based on the assigned destination floor call in the n-th car (S3). Assigned means a state in which a destination floor call is assigned to Unit A with respect to a destination floor call previously registered by another passenger different from the passenger who newly registered the destination floor call. The car 2n represents one of the cars 2A to 2C. If the variable n is “1”, the car 2A, “2” represents the car 2B, and “3” represents the car 2C. Next, the comparison unit 11 calculates the remaining power (predicted remaining power) of the car 2n after the service is completed by the assigned destination floor call in the n-th car (S4). For example, in steps S3 and S4, the amount of power consumed and the amount of power remaining by the assigned destination floor call in the car 2A of the No. A car are obtained.

  Next, the comparison unit 11 calculates the power consumption (predicted power consumption) when the newly registered destination floor call is assigned to the n-th unit (S5), and the remaining power ( (Predicted remaining power) is calculated (S6). For example, in steps S5 and S6, the amount of power consumed and the amount of remaining power are obtained by a newly registered destination floor call in the car 2A of the A-unit.

  Next, the comparison unit 11 calculates the waiting time of the n-th unit for the newly registered destination floor call (S7). For example, if the car 2A of Unit A is waiting near the floor where the destination floor call is newly registered, the waiting time will be calculated less, but if it is moving to a distant floor, it will wait A lot of time is calculated.

  Then, the comparison unit 11 calculates the allocation evaluation value of the n-th unit based on the power consumption amount and remaining power of the n-th unit calculated in steps S5 and S6 and the waiting time calculated in step S7. (S8). Allocation evaluation value is a value assigned to each unit that is referenced when selecting a unit to which a destination floor call is allocated. As described above, a high allocation evaluation value is assigned to a unit having a large amount of predicted power consumption of the device. Therefore, a destination floor call is assigned in preference to a machine having a high assignment evaluation value.

  Next, the comparison unit 11 adds “1” to the variable n (S9). In the description so far, since “1” has been set to the variable n, when the variable n is set to “2”, in the following description, the processing related to Unit B is performed.

  Next, the comparison unit 11 determines whether or not the variable n exceeds a fixed value Nmax (S10). The fixed value Nmax is, for example, the number of all the machines, and “3” is set in the present embodiment. An arbitrary value is set to the fixed value Nmax in accordance with the number of units that can be managed by the group management control device 7.

  In the above description, since “2” of the variable n is smaller than “3” of the fixed value Nmax (NO in S10), the process proceeds to step S3. Then, the comparison unit 11 calculates the power consumption by the assigned destination floor call in Unit B and the remaining power after service completion (S3, S4), and the power consumption when a new destination floor call is assigned. And the remaining electric power after service completion is calculated (S5, S6). Then, the comparison unit 11 calculates the waiting time (S7), calculates the allocation evaluation value (S8), adds "1" to the variable n (S9), and sets the variable n to "3".

  Even if the variable n is set to “3”, since it does not exceed the fixed value Nmax (NO in S10), the process proceeds to step S3, and the processing from steps S3 to S7 in Unit C is performed to calculate the allocation evaluation value ( S8). Then, the comparison unit 11 adds “1” to the variable n (S9), and sets the variable n to “4”. Since the variable n “4” exceeds the fixed value Nmax “3” (YES in S10), the process proceeds to step S11.

  And the number machine operation control part 12 allocates a destination floor call to the number machine with a high allocation evaluation value (S11). A unit having a high allocation evaluation value is selected that can cope with a destination floor call in which the predicted remaining power is newly registered and has the shortest waiting time. Then, this process ends.

  The group management control device 7 according to the first embodiment described above has the operation data and the remaining power transmitted from the machine control devices 6A to 6C at the timing when the destination floor call is registered in the destination floor call registration device 8. Receive quantity data. Then, the comparison unit 11 of the group management control device 7 compares the predicted consumption power amount and the remaining power amount for each unit, calculated using the operation history for each unit and the change in the remaining power amount, and assigns the evaluation value. Calculate The unit operation control unit 12 can control the operation by giving priority to the unit having a high allocation evaluation value calculated by the comparison unit 11.

  Here, the required power shown in the power consumption table T1 is calculated for each unit based on the latest operation history and the change in the remaining power. Each time the destination floor call is registered, the comparison unit 11 accurately predicts the predicted power consumption in the operation for a certain floor by using this necessary power, and also predicts the predicted power remaining amount. For this reason, it is not necessary to add further reserve power to the predicted power consumption as in the conventional case. And even if there is an individual difference in increase / decrease in power consumption for each unit, the unit operation control unit 12 is a desirable unit for assigning a destination floor call based on accurate information at the time when the destination floor call is registered. Control that is offset is possible.

  Further, when the predicted consumption power amount and the predicted remaining power level are accurately predicted by the comparison unit 11, the unit operation control unit 12 continues the operation of the car until the remaining power level becomes equal to or less than the charging threshold th1. Can do. For this reason, the operation rate in the predetermined period for every number machine can be raised.

  Moreover, the comparison part 11 sets the lowest allocation evaluation value with respect to the car number of the car provided with the power storage device whose remaining power is equal to or less than the charging threshold th1. And the number machine operation control part 12 moves a passenger car to an electric power feeding floor, after prohibiting allocation of the new destination floor call to the said number machine. For this reason, it is possible to continue the service with the remaining units except for the unit that is being fed, from the assignment of the destination floor call.

  In addition, the deterioration of the device can be further advanced by performing a control to give priority to a car having a large amount of power consumption of the device due to the progress of the deterioration of the device. For this reason, the replacement timing of equipment that has deteriorated can be made different from the replacement timing of equipment used in other cars, and services are provided by stopping multiple equipment at the same time for equipment replacement. The situation that can not be done is avoided.

  If the equipment used in the car deteriorates, the predicted power consumption of the power storage device increases. Therefore, if the predicted power consumption of the power storage device is large in spite of normal use, the unit operation control unit 12 The device replacement instruction information may be transmitted to a monitoring center (not shown). The monitoring center that has received the replacement instruction information, for example, presents an instruction to the operator to replace the device with a new one during regular maintenance. A device replaced with a new one consumes less power than a deteriorated device. For this reason, the power consumption of the power storage device that supplies power to the device can be suppressed, and the number of times of power feeding to the power storage device within a predetermined period (for example, one month) can be reduced.

  Further, the power supply device may contact the power reception device to supply power. Even in this case, the power receiving device can charge the power storage device with the power supplied from the power feeding device.

[Second Embodiment]
Next, a group management control system according to the second embodiment of the present invention will be described. In this group management control system, operation control that is offset by a specific unit is performed so that the replacement times of the power storage devices that are predicted to deteriorate are not overlapped by a plurality of units.

  FIG. 6 is an explanatory diagram illustrating a schematic configuration example of the group management control system 1A according to the second embodiment.

  The method in which the machine operation control unit 12 controls the operation of each machine is not limited to the method shown in the first embodiment. For example, in order to replace the power storage devices installed in a plurality of units at the same time, there has been a demand to avoid that a plurality of units stop at the same time and the number of serviceable units decreases. Therefore, in the second embodiment, deterioration of the power storage devices 4A to 4C is predicted in advance, and the prediction result is used for group management control.

  The group management control device 7 included in the group management control system 1A includes a deterioration prediction unit 13 in addition to the comparison unit 11 and the number machine operation control unit 12 according to the first embodiment. The group management control device 7 includes a power consumption table T2.

  The deterioration prediction unit 13 predicts the progress of deterioration of the power storage devices 4A to 4C for each unit based on the change in the operation history and the remaining power. Here, the deterioration prediction unit 13 predicts the deterioration of the power storage devices 4A to 4C using, for example, the voltage of the power storage devices 4A to 4C, the predicted power consumption, the time required for charging and discharging, and the like. When the power storage devices 4A to 4C are viewed as capacitors, the electrostatic energy E that can be stored in the capacitors is calculated by the following equation (1) using the capacitor capacity C and the voltage V of the capacitors.

E = (1/2) CV ² [J] (1)

  In general, the progress of deterioration of a power storage device is represented by a decrease in the capacity C of a usable capacitor. When the voltage for charging the power storage device is constant, the electrostatic energy E decreases as the capacitance C of the capacitor decreases, so the time required for charging and discharging the power storage device decreases. For this reason, the comparison unit 11 can compare the progress of deterioration of the power storage devices 4A to 4C of each unit based on the time required for charging and discharging the power storage devices. As described above, the time required for charging / discharging can be obtained from the measurement time by the remaining power measuring devices 5A to 5C. For example, the comparison unit 11 determines the progress of deterioration for each power storage device by confirming the predicted power consumption, the voltage decrease with respect to the discharge time, and the voltage increase with respect to the charge time. For example, if the voltage when fully charging a currently used power storage device is low and the charge / discharge time is short with respect to the voltage and charge / discharge time when a new power storage device is fully charged, this power storage device It is determined that the deterioration of is progressing. Then, comparison unit 11 calculates a degradation evaluation value indicating the progress of degradation for each of power storage devices 4A to 4C. The deterioration evaluation value is set to a smaller value as the deterioration of the power storage device proceeds.

  The unit operation control unit 12 gives priority to a car having a power storage device that is predicted to be deteriorated by the deterioration prediction unit 13, so that the replacement times of the power storage devices 4A to 4C are a plurality of units. Perform group management control that is offset so that they do not overlap. By such operation control, the number machine operation control unit 12 prevents the replacement timings of the power storage devices 4A to 4C from overlapping each other.

FIG. 7 is an explanatory diagram of the power consumption table T2. In the power consumption table T2, the operation history and the remaining power amount managed by the comparison unit 11 are stored. The power consumption table T2 is stored in the RAM C3 or the non-volatile storage C5 provided in the group management control device 7, and can be read as appropriate by the comparison unit 11.
FIG. 8 is an explanatory diagram illustrating an example of the storage capacities of the power storage devices 4A to 4C.

  The power consumption table T2 manages the operation history and the change in the remaining power for each unit. In the power consumption table T2, the remaining amount of power and the required power are represented by a power amount [Wh]. The electric energy [Wh] is a value obtained by converting the electrostatic energy E [J] of the capacitor used in the power storage device.

  And the average power consumption of the apparatus used for every car is updated at the timing which supplies electric power to each power storage device. For example, when a destination floor call from the first floor to the tenth floor is registered, “power consumption due to door opening / closing on the first floor” + “power consumption required for movement of the ninth floor from the first floor to the tenth floor” + “Power consumption due to door opening / closing on the 10th floor” is the predicted power consumption predicted by the comparison unit 11.

  Also, consider a case where a destination floor call from the 6th floor to the 10th floor is newly registered in a situation where a destination floor call from the 1st floor to the 6th floor is registered. In this case, “power consumption by opening / closing the door on the first floor” + “power consumption for moving the fifth floor from the first floor to the sixth floor” + “power consumption by opening / closing the door on the sixth floor” + “6th floor Power consumption required for the movement of the fourth floor from the first floor to the 10th floor ”+“ power consumption due to door opening / closing on the 10th floor ”is the predicted power consumption predicted by the comparison unit 11. And the required power which put together the average power consumption of each apparatus in various driving | running states estimated by the comparison part 11 is stored in the power consumption table T2.

  As described above, the power storage capacities of the power storage devices 4A to 4C change as the capacitors deteriorate. That is, the power storage devices 4A to 4C are deteriorated by repeating charge and discharge. For example, when the power storage capacity of the power storage device 4C of Unit C is 100% of the initial value, when the power storage device 4C is fully charged, the remaining power becomes 100 Wh. However, when the deterioration of the power storage device 4A of Unit A progresses and the power storage capacity of the power storage device 4A is 80% of the initial value, the remaining amount of power becomes 100 Wh × 0.8 = 80 Wh even when the power storage device 4A is fully charged. It must be. Similarly, when the deterioration of the power storage device 4B of Unit B progresses and the power storage capacity of the power storage device 4B is 70% of the initial value, the remaining power is 100 Wh × 0.7 = 70 Wh even when the power storage device 4B is fully charged. It can only be.

  Depending on the progress of deterioration of devices used in the cars 2A to 2C, individual differences of devices, etc., the required power differs even for the same floor. For example, in Unit A, the required power for moving the 10th floor is 9 Wh, in Unit B, 11 Wh, and in Unit C, 10 Wh.

  Therefore, as shown in FIG. 7, if the state of charge is full, the remaining power of the power storage device 4A is reduced from 80 Wh to 71 Wh for the operation from the first floor to the tenth floor by the car 2A of Unit A. Shown to change. Similarly, in Unit B, the remaining power of the power storage device 4B changes from 70 Wh to 59 Wh, and in Unit C, the remaining power of the power storage device 4C changes from 100 Wh to 90 Wh.

  When the state of charge is 3/4 of the storage capacity, the remaining amounts of power of the storage devices 4A, 4B, and 4C are 60 Wh, 52.5 Wh, and 75 Wh, respectively, with respect to the fully charged storage capacity. Then, when the cars 2A to 2C of each unit are operated from the 1st floor to the 10th floor, the respective remaining electric power changes to 51 Wh, 41.5 Wh, and 65 Wh.

  When the state of charge is half of the storage capacity, the remaining power of the power storage devices 4A, 4B, and 4C is 40 Wh, 35 Wh, and 50 Wh, respectively, with respect to the fully charged storage capacity. And when the cars 2A to 2C of each unit operate from the first floor to the 20th floor, 18Wh, 22Wh, which doubles the power required when the cars 2A to 2C operate from the first floor to the 10th floor, 20 Wh is required power. For this reason, the remaining electric power of the power storage devices 4A, 4B, and 4C changes to 22 Wh, 13 Wh, and 30 Wh. For example, if the remaining power after operation is less than 20% (20Wh) of the initial storage capacity, if assignment is not possible, assign it to the destination floor call that operates from the first floor to the 20th floor. I can't. For this reason, No. A or No. C is assigned to a destination floor call that operates from the first floor to the 20th floor.

  FIG. 9 is a flowchart illustrating an example of the bias control according to the deterioration evaluation value of the power storage device. The process shown in FIG. 9 is a process in which the unit operation control unit 12 determines whether or not charging is necessary for the power storage device of the unit having the lowest allocation evaluation value after the destination floor call is assigned to the unit by the process shown in FIG. It is. Here, the process is performed for the power storage device 4B of Unit B from the power consumption table T2 of FIG.

  First, the number machine operation control unit 12 determines whether the predicted remaining power level of the power storage device 4B is equal to or less than the charging threshold th1 (see FIG. 2) based on the remaining power data (S11). If the predicted remaining power exceeds the charging threshold th1 (NO in S11), charging of the power storage device 4B is unnecessary, and thus this process is terminated.

  If the predicted remaining power is equal to or less than the charging threshold th1 (YES in S11), the car operation control unit 12 performs control to move the car 2B including the power storage device 4B to the power supply floor (S12). When the car 2B stops on the power supply floor, charging of the power storage device 4B via the power receiving device 3B by the power supply device 21B is started. At this time, the remaining power measurement device 5B starts measuring the charging time until the voltage of the power storage device 4B is E [V], that is, fully charged (S13).

  During charging of the power storage device 4B, the comparison unit 11 of the group management control device 7 opens and closes the car door when the car 2B moves based on the operation history from the previous power supply to the power storage device 4B to the current power supply. The average power consumption at the time of standby and standby is calculated, and the average power consumption is collected as necessary power, and the power consumption table T2 is updated (S14). By this process, for example, the required power in the column of the state of charge in the power consumption table T2 is updated.

  When the charging of the power storage device 4B is completed, the remaining power measurement device 5B ends the measurement of the charging time (S15). At this time, the voltage of the power storage device 4B is E [V], that is, the battery is fully charged.

  Next, the comparison unit 11 of the group management control device 7 determines the power storage device based on the operation history from the previous power supply to the current power supply device 4B to the current power supply, the power consumption, the energization time and the charge time in each operation state. A deterioration evaluation value of 4B is calculated (S16). The deterioration evaluation value is obtained from, for example, the time until the voltage of the power storage device 4B at the time of power feeding returns to the voltage value at full charge. For example, if the power storage device 4B is not fully degraded, it is evaluated that the power storage device 4B is fully degraded when it is fully charged in 60 seconds, even though the battery is fully charged in 100 seconds. The deterioration evaluation value is set to such a small value that the deterioration of the power storage device 4B proceeds. For example, “5” when the storage capacity of the power storage device 4B is 100% of the initial value, “3” when it is 80% of the initial value, and “1” when it is 60% of the initial value. Is a degradation evaluation value.

  Next, the number machine operation control part 12 judges whether the deterioration evaluation value of the electrical storage apparatus 4B is below a deterioration threshold value (for example, "1") (S17). For example, when the deterioration evaluation value of the power storage device 4B is “2” and is not equal to or less than the deterioration threshold (NO in S17), the deterioration of the power storage device 4B has not progressed, and the offset control of the car 2B is not necessary yet. Therefore, this process ends.

  On the other hand, when the degradation evaluation value of power storage device 4B is “1” and is equal to or less than the degradation threshold (YES in S17), it is necessary to use this power storage device 4B as much as possible to advance the replacement timing of power storage device 4B. . For this reason, an allocation priority flag used for preferentially allocating the destination floor call is set (S18). Units for which the allocation priority flag has been set are subject to offset control. Then, the assigned evaluation value of this car is set high, and the car of this car is easily assigned with priority. Thereafter, this process is terminated.

  When the progress of the deterioration of the power storage device is different among a plurality of units, the unit operation control unit 12 is connected to the car of the car in which the power storage device that is predicted to have the most deterioration is installed, and then the deterioration Group management control is performed in which priority is given to the other car in which another power storage device that is predicted to be installed is installed. For example, the car 2B having the most deteriorated power storage device 4B and the car 2A having the next deteriorated power storage device 4A are controlled to be offset so that, for example, the car 2B Group management control can be performed with priority only on the car 2A. In this case, the deterioration can be advanced not only in the power storage device 4B in which the deterioration has progressed but also in the power storage device 4A. However, as for the power storage device 4A, in order to make the replacement time different from that of the power storage device 4B, the car 2A and the car 2C equipped with the power storage device 4C that has not deteriorated are appropriately subject to group management control. Treat as. Thereby, only the progress of the deterioration of the power storage device 4B is accelerated, and it becomes possible to preferentially replace only the power storage device 4B at the replacement time.

  In the group management control system 1A according to the second embodiment described above, when there are a plurality of assignable units, priority is given to the unit having the power storage device in which the deterioration is most advanced among the power storage devices 4A to 4C. And control to dispatch. Such deviation control can further accelerate the progress of the deterioration of the power storage device in which the deterioration has progressed. In the maintenance replacement period, it is possible to preferentially replace only the power storage device that has deteriorated. For this reason, it is possible to avoid a situation in which the operating rate is lowered by simultaneously replacing the power storage devices of a plurality of units at the maintenance replacement time.

  In addition, since the unit operation control unit 12 can accurately grasp the power storage device in which deterioration has progressed, operation control of the cars 2A to 2C is performed so that the progress of deterioration of the power storage device can be controlled. It becomes possible to do.
