The state data is data representing the operation state of the elevator 2.

The data acquisition system 1 includes a plurality of remote monitoring devices 13 and a data acquisition device 14.

Each of the plurality of remote monitoring devices 13 is an example of a storage device. Each of the plurality of remote monitoring devices 13 corresponds to each of the plurality of elevators 2. Each of the plurality of remote monitoring devices 13 is provided, for example, in a management room of the building 3 where the corresponding elevator 2 is provided. Each of the plurality of remote monitoring devices 13 includes a first storage unit 131, a generation unit 132, a second storage unit 133, and a transmission unit 134.

The first storage unit 131 is connected to the control panel 11 so as to receive the state data. The 1st memory | storage part 131 is comprised so that it can memorize | store while updating driving | operation data with the received status data. The operation data is data representing the operation state of the elevator 2. Here, the driving state includes, for example, driving history and information on abnormality or modulation. Modulation is a change before it becomes abnormal.

The generation unit 132 is connected to the first storage unit 131 so that operation data can be acquired. The generation unit 132 is configured to be able to generate reproduction data from the operation data at the reporting period switching time. The reporting period is a period in which the history of operation of the elevator 2 and abnormality or modulation are reported to the administrator of the elevator 2 and the like.

The data acquisition unit 141 is connected to each of the plurality of remote monitoring devices 13 through the communication line 15 so that the reproduction data can be received based on the data acquisition table. The data acquisition table is a table that associates a reporting period and a data acquisition time for each of the plurality of elevators 2. The data acquisition time is a time at which each of the remote monitoring devices 13 corresponding to each of the plurality of elevators 2 and the data acquisition unit 141 perform data communication. As the data acquisition time, different times are set for each of the plurality of elevators 2. The data acquisition unit 141 is configured to reproduce the operation data at the reporting period switching time based on the acquired data.

The operation data storage unit 142 is configured to store operation data.

The report data generation unit 143 is connected to the operation data storage unit 142 so that the operation data can be acquired. The report data generation unit 143 is configured to generate report data based on the acquired operation data. The report data includes a history of operation of the elevator 2 during the report period and an abnormality or modulation.

During operation of the elevator 2, the control panel 11 activates the hoisting machine 9. The main rope 10 is driven by the hoisting machine 9 and moves. The car 7 and the balance weight 8 move up and down following the movement of the main rope 10 along a guide rail (not shown). The car 7 stops on the floor where the hall 5 is provided. The landing door 6 opens in conjunction with the car door 12. A user of the elevator 2 gets on or off the car 7 from the landing 5.

The control panel 11 stores the operation data while updating it. At the reporting period switching time, the control panel 11 generates reproduction data. The data acquisition device 14 acquires reproduction data from each of the plurality of elevators 2 at different times based on the data acquisition table. The data acquisition device 14 reproduces the operation data from the reproduction data. The data acquisition device 14 generates report data from the reproduced operation data.

Next, an example of the data acquisition table will be described with reference to FIG.
FIG. 2 is a diagram illustrating an example of a data acquisition table according to the first embodiment.

The data acquisition table is stored in the data acquisition unit 141.

The data acquisition table associates, for example, a reporting period, report data generation time, and data acquisition time for each of the plurality of elevators 2. The report data generation time is the time when the report data is generated from the operation data reproduced by the data acquisition device 14. The end time of the reporting period is the start time of the next reporting period. Here, 24:00 on one day is the same time as 0:00 on the next day. The reporting period in which the data acquisition table is associated with each of the plurality of elevators 2 is the same as that of the generation unit 132 of the remote monitoring device 13 corresponding to each elevator 2.

In this example, the reporting period of the elevator E1 is from 0:00 on the first day of every month until 24:00 on the last day of the month. The end time of the reporting period of the elevator E1 is 24:00 on the last day of every month. The report data generation time of the elevator E1 is 12:00 on the 15th of the following month. The data acquisition time of the elevator E1 is 0:30 on the 5th of the following month.

The elevator E2 reporting period is from 0:00 on the first day of every month until 24:00 on the last day of the month. The report data generation time of the elevator E2 is 12:00 on the 20th of the following month. The data acquisition time of the elevator E2 is 3:00 on the 10th of the next month.

The reporting period of the elevator E3 is from 0:00 on the first day of every month until 24:00 on the last day of the month. The report data generation time of the elevator E3 is 12:00 on the 20th of the following month. The data acquisition time of the elevator E3 is 4:45 on the 15th of the next month.

The reporting periods of the elevator E1, the elevator E2, and the elevator E3 are the same. The data acquisition times of the elevator E1, the elevator E2, and the elevator E3 are different from each other.

Next, functions of the data acquisition system 1 will be described with reference to FIG.
FIG. 3 is a diagram illustrating an example of data in the data acquisition system according to the first embodiment.
In FIG. 3, the case where the March report data is generated for the elevator E <b> 2 in FIG. 2 will be described as an example.

The operation data D1 includes history data Da and measurement data Db. The history data Da is data to which an element associated with time is added by updating. The element of the history data Da is, for example, a code representing the time associated with the time when the abnormality or modulation event occurs. In FIG. 3, only the date is displayed among the times associated with the element. The measurement data Db is data in which the value of the element changes due to the update. The elements of the measurement data Db are, for example, the number of activations of the hoisting machine 9, the accumulated traveling time of the car 7, or the number of times of opening and closing the car door 12. In FIG. 3, the number of activations is displayed as an example of a part of the elements of the measurement data Db.

When receiving state data representing an abnormality or modulation event, the first storage unit 131 adds a code representing the event as an element of the history data Da in association with the time at which the event occurred. The first storage unit 131 continues to store added elements within the storage capacity range. When the storage capacity is insufficient, the first storage unit 131 deletes elements associated with old times. The first storage unit 131 has a sufficient storage capacity because, for example, elements are not deleted for at least two months. That is, the first storage unit 131 stores history data Da including information before March.

When receiving the state data representing the start-up of the hoisting machine 9, the first storage unit 131 adds 1 to the value of the element of the measurement data Db representing the number of times the hoisting machine 9 is activated. The first storage unit 131 stores, for example, the number of activations accumulated for at least two months or more as one value of elements of the measurement data Db. That is, the first storage unit 131 stores measurement data Db including information before March.

The generation unit 132 of the remote monitoring device 13 acquires the operation data D1 from the first storage unit 131 at 0:00 on March 1st. 0:00 on March 1 is the end time of the February reporting period and the start time of the March reporting period. The generation unit 132 generates reproduction data D2 by copying the acquired operation data D1. The reproduction data D2 generated by the generation unit 132 is the same as the operation data D1 at 0:00 on March 1. That is, the reproduction data D2 includes history data Da and measurement data Db. The generation unit 132 transmits the reproduction data D2 to the second storage unit 133.

The second storage unit 133 stores reproduction data D2. The second storage unit 133 updates the stored reproduction data D2 by overwriting with the reproduction data D2 received from the generation unit 132. During the March reporting period, the second storage unit 133 stores reproduction data D2 that is the same as the operation data D1 at 0:00 on March 1.

The data acquisition unit 141 of the data acquisition device 14 transmits a data request signal to the remote monitoring device 13 corresponding to the elevator E2 at 3:00 on March 10th. 3:00 on March 10 is the data acquisition time associated with the elevator E2 by the data acquisition table.

When receiving the data request signal, the transmission unit 134 of the remote monitoring device 13 acquires the reproduction data D2 from the second storage unit 133. The transmission unit 134 transmits the reproduction data D2 to the data acquisition unit 141.

The data acquisition unit 141 reproduces the operation data D1 at 0:00 on March 1 by copying the acquired reproduction data D2. The data acquisition unit 141 transmits the reproduced operation data D1 to the operation data storage unit 142.

The operation data storage unit 142 stores the operation data D1 at the end time of the received report period in February.

Similarly, in April, the data acquisition device 14 reproduces the operation data D1 at 0:00 on April 1 with the reproduction data D2 acquired at 3:00 on April 10. 0:00 on April 1 is the end time of the March report period and the start time of the April report period. 3:00 on April 10 is the data acquisition time associated with the elevator E2 by the data acquisition table.

At the report data generation time of the elevator E2, the report data generation unit 143 acquires the operation data D1 at the end time of the February report period and the operation data D1 at the end time of the March report period from the operation data storage unit 142. . The report data generation unit 143 generates report data D3 based on the acquired operation data D1.

The report data generation unit 143 extracts elements that are not included in the history data Da at the end time of the February report period and are included in the history data Da at the end time of the March report period. In this example, the report data generation unit 143 extracts an element representing the event B that occurred on March 2 and an element representing the event C that occurred on March 12. The report data generation unit 143 sets the extracted element as the history data Da of the report data D3.

The report data generation unit 143 calculates a difference between the element value of the measurement data Db at the end time of the February report period and the element value of the measurement data Db at the end time of the March report period. In this example, the report data generation unit 143 calculates the difference between the number of activations of 30000 at 0:00 on March 1 and the number of activations of 31000 at 0:00 on April 1 as 1000. The report data generation unit 143 sets the calculated value as the element value of the measurement data Db of the report data D3.

Next, the operation of the remote monitoring device 13 will be described with reference to FIG.
FIG. 4 is a flowchart showing an example of the operation of the remote monitoring apparatus according to the first embodiment.

In step S101, the first storage unit 131 updates the stored operation data based on the received state data. Thereafter, the operation of the remote monitoring device 13 proceeds to step S102.

In step S102, the generation unit 132 determines whether the current time is the reporting period switching time. If the determination result is Yes, the operation of the remote monitoring device 13 proceeds to step S103. When the determination result is No, the operation of the remote monitoring device 13 proceeds to step S104.

In step S103, the generation unit 132 generates reproduction data. Thereafter, the second storage unit 133 updates the stored reproduction data based on the reproduction data received from the generation unit 132. Thereafter, the operation of the remote monitoring device 13 proceeds to step S104.

In step S104, the transmission unit 134 determines whether a data request signal has been received. When the determination result is No, the operation of the remote monitoring device 13 proceeds to step S101. If the determination result is Yes, the operation of the remote monitoring device 13 proceeds to step S105.

In step S105, the transmission unit 134 transmits the reproduction data to the data acquisition device 14. Thereafter, the operation of the remote monitoring device 13 proceeds to step S101.

Next, the operation of the data acquisition device 14 will be described with reference to FIG.
FIG. 5 is a flowchart illustrating an example of the operation of the data acquisition apparatus according to the first embodiment.

In step S201, the data acquisition unit 141 selects one elevator 2 from the unselected list. The unselected list is a list of elevators 2 that are not yet selected. Thereafter, the data acquisition unit 141 removes the selected elevator 2 from the unselected list. Thereafter, the operation of the data acquisition device 14 proceeds to step S202.

In step S202, the data acquisition unit 141 determines whether the current time is the data acquisition time of the selected elevator 2 based on the data acquisition table. If the determination result is Yes, the operation of the data acquisition device 14 proceeds to step S203. If the determination result is No, the operation of the data acquisition device 14 proceeds to step S205.

In step S203, the data acquisition unit 141 transmits a data request signal to the remote monitoring device 13 corresponding to the selected elevator 2. Thereafter, the data acquisition unit 141 waits until the reproduction data is received from the remote monitoring device 13. Thereafter, the operation of the data acquisition device 14 proceeds to step S204.

In step S204, the data acquisition unit 141 reproduces the operation data at the switching time of the reporting period of the selected elevator 2 based on the received reproduction data. Thereafter, the operation data storage unit 142 stores the operation data reproduced by the data acquisition unit 141. Thereafter, the operation of the data acquisition device 14 proceeds to step S205.

In step S205, the report data generation unit 143 determines whether the current time is the report data generation time of the selected elevator 2 based on the data acquisition table. If the determination result is Yes, the operation of the data acquisition device 14 proceeds to step S206. If the determination result is No, the operation of the data acquisition device 14 proceeds to step S207.

In step S206, the report data generation unit 143 generates report data. Thereafter, the operation of the data acquisition device 14 proceeds to step S207.

In step S207, the data acquisition unit 141 determines whether all the elevators 2 have been selected based on, for example, whether the unselected list is empty. If the determination result is No, the operation of the data acquisition device 14 proceeds to step S201. If the determination result is Yes, the operation of the data acquisition device 14 proceeds to step S208.

In step S208, the report data generation unit 143 resets the unselected list by returning all elevators 2 to the unselected list based on, for example, the data acquisition table. Thereafter, the operation of the data acquisition device 14 proceeds to step S201.

As described above, the data acquisition system 1 according to the first embodiment includes the plurality of remote monitoring devices 13 and the data acquisition device 14. Each of the plurality of remote monitoring devices 13 stores the operation data of the corresponding elevator 2 while updating it. Each of the plurality of remote monitoring devices 13 stores reproduction data. The reproduction data is data for reproducing the operation data at the switching time of the reporting period after the switching time. The data acquisition device 14 acquires reproduction data from each of the plurality of remote monitoring devices 13 at different times after the switching time.

The data for reproduction is generated by each of the plurality of remote monitoring devices 13 at the same time without communication with the data acquisition device 14. On the other hand, the communication of the reproduction data is performed at different times for each of the plurality of remote monitoring devices 13. Thereby, the data acquisition device 14 can distribute communication for obtaining operation data in the same report period at different times for each of the plurality of remote monitoring devices 13. The data acquisition system 1 does not need to communicate at the same time to obtain operation data at the same time. For this reason, the data acquisition system 1 can obtain operation data at the same time without adding a communication device to perform communication at the same time.

Reproduction data is generated without communication with the data acquisition device 14. Thereby, the data acquisition device 14 can obtain the operation data at the designated time regardless of the communication status.

Further, each of the plurality of remote monitoring devices 13 stores the operation data at the switching time as reproduction data.

The second storage unit 133 stores the same reproduction data as the operation data at the switching time. As a result, the data acquisition unit 141 can easily reproduce the operation data by copying, for example.

The control panel 11 may function as a storage device instead of the remote monitoring device 13 or in cooperation with the remote monitoring device 13. The storage device may be provided separately from the control panel 11 and the remote monitoring device 13.

Some or all of the plurality of elevators 2 may be provided in the same building 3.

The report period, data acquisition time, and report data generation time stored in the remote monitoring device 13 and the data acquisition device 14 may be changed by a remote signal or a direct operation by a maintenance person or the like.

The reporting period of a part of the plurality of elevators 2 may be different from the other part of the plurality of elevators 2. The reporting period may be a period longer than one month or a shorter period.

* Report data may be generated by operations of maintenance personnel. The report data generation time may be the same for some or all of the plurality of elevators 2.

Next, an example of the hardware configuration of the data acquisition system 1 will be described with reference to FIG.
FIG. 6 is a diagram illustrating a hardware configuration of a main part of the data acquisition system according to the first embodiment.

Each function of the data acquisition system 1 can be realized by a processing circuit. The processing circuit includes at least one processor 1b and at least one memory 1c. The processing circuit may include at least one dedicated hardware 1a together with or in place of the processor 1b and the memory 1c.

When the processing circuit includes the processor 1b and the memory 1c, each function of the data acquisition system 1 is realized by software, firmware, or a combination of software and firmware. At least one of software and firmware is described as a program. The program is stored in the memory 1c. The processor 1b implements each function of the data acquisition system 1 by reading and executing a program stored in the memory 1c.

The processor 1b is also referred to as a CPU (Central Processing Unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, and a DSP. The memory 1c includes, for example, a nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, and an EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, and a DVD.

When the processing circuit includes dedicated hardware 1a, the processing circuit is realized by, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

Each function of the data acquisition system 1 can be realized by a processing circuit. Or each function of the data acquisition system 1 can also be implement | achieved by a processing circuit collectively. A part of each function of the data acquisition system 1 may be realized by the dedicated hardware 1a, and the other part may be realized by software or firmware. In this way, the processing circuit realizes each function of the data acquisition system 1 with the hardware 1a, software, firmware, or a combination thereof.

Embodiment 2. FIG.
In the second embodiment, differences from the example disclosed in the first embodiment will be described in detail. For features not described in the second embodiment, any of the features disclosed in the first embodiment may be adopted.

FIG. 7 is a diagram illustrating an example of data in the data acquisition system according to the second embodiment.
In FIG. 7, a case where the March report data is generated for the elevator E <b> 2 in FIG. 2 will be described as an example.

The transmission unit 134 of the remote monitoring device 13 is connected to the first storage unit 131 so that operation data can be acquired. The transmission unit 134 is connected to the second storage unit 133 so that the reproduction data can be acquired. The transmission unit 134 is connected to the data acquisition device 14 through the communication line 15 so that the operation data and the reproduction data can be transmitted.

The data acquisition unit 141 of the data acquisition device 14 is connected to each of the plurality of remote monitoring devices 13 through the communication line 15 so that the operation data and the reproduction data can be received based on the data acquisition table.

The generation unit 132 of the remote monitoring device 13 acquires the measurement data Db of the operation data D1 from the first storage unit 131 at 0:00 on March 1st. 0:00 on March 1 is the end time of the February reporting period and the start time of the March reporting period. The generation unit 132 generates reproduction data D2 by copying the acquired measurement data Db. The reproduction data D2 generated by the generation unit 132 is the same as the measurement data Db of the operation data D1 at 0:00 on March 1. The generation unit 132 transmits the reproduction data D2 to the second storage unit 133.

The second storage unit 133 stores reproduction data D2. The second storage unit 133 updates the stored reproduction data D2 by overwriting with the reproduction data D2 received from the generation unit 132. During the March reporting period, the second storage unit 133 stores reproduction data D2 that is the same as the measurement data Db of the operation data D1 at 0:00 on March 1.

When receiving the data request signal, the transmission unit 134 of the remote monitoring device 13 acquires the reproduction data D2 from the second storage unit 133. The transmission unit 134 transmits the operation data D1 and the reproduction data D2 to the data acquisition unit 141.

The data acquisition unit 141 extracts elements associated with the time before 0:00 on March 1 from the history data Da of the acquired operation data D1. The data acquisition unit 141 generates history data Da based on the extracted elements. The data acquisition unit 141 generates measurement data Db by copying the acquired reproduction data D2. The data acquisition unit 141 reproduces the operation data D1 at 0:00 on March 1 with the generated history data Da and measurement data Db. The data acquisition unit 141 transmits the reproduced operation data D1 to the operation data storage unit 142.

As described above, each of the plurality of remote monitoring devices 13 according to the second embodiment stores measurement data and history data as operation data. In the measurement data, the value of the element changes by updating. The history data is added with an element associated with the time by updating. Each of the plurality of remote monitoring devices 13 stores the measurement data at the reporting period switching time as reproduction data.

The second storage unit 133 stores the same measurement data as the operation data at the switching time. Thereby, the data acquisition unit 141 can easily reproduce the measurement data of the operation data by copying, for example. The elements of the history data are associated with the time. For this reason, the data acquisition unit 141 can reproduce the operation data at the switching time from the operation data at the current time. Therefore, the reproduction data can be composed only of data for reproducing the measurement data. Thereby, the storage capacity required for the second storage unit 133 is reduced.

The function of the data acquisition system 1 will be described with reference to FIG.
FIG. 8 is a diagram illustrating an example of data in the data acquisition system according to the third embodiment.
In FIG. 8, a case where report data for March is generated for the elevator E2 in FIG. 2 will be described as an example.

The generation unit 132 of the remote monitoring device 13 is connected to the control panel 11 so as to receive the state data. The generation unit 132 is connected to the second storage unit 133 so that the reproduction data can be updated with the received state data.

The generation unit 132 resets the reproduction data at 0:00 on March 1. The generation unit 132 resets the history data of the reproduction data by emptying the element. The generation unit 132 resets the measurement data of the reproduction data by setting the value of the element to 0, for example. 0:00 on March 1 is the end time of the February reporting period and the start time of the March reporting period.

When receiving the state data representing an abnormality or modulation event, the generation unit 132 adds a code representing the event as an element of the history data Da of the reproduction data D2 in association with the time when the event occurred. When receiving the state data indicating the activation of the hoisting machine 9, the generating unit 132 adds 1 to the value of the element of the measurement data Db of the reproduction data D2 representing the number of activations of the hoisting machine 9. The generation unit 132 generates reproduction data D2 based on the history data Da and the measurement data Db. The generation unit 132 transmits the reproduction data D2 to the second storage unit 133.

The second storage unit 133 stores reproduction data D2. The second storage unit 133 updates the stored reproduction data D2 by overwriting with the reproduction data D2 received from the generation unit 132. During the March reporting period, the second storage unit 133 stores the reproduction data D2 while updating the reproduction data D2 with the same change as the operation data D1, with 0:00 on March 1 as a base point. That is, the reproduction data D2 represents the difference between the operation data at 0:00 on March 1 and the operation data at the current time.

The data acquisition unit 141 reproduces the operation data D1 at 0:00 on March 1 by pulling back the difference represented by the reproduction data D2 from the operation data D1. The data acquisition unit 141 pulls back the history data Da by extracting elements included in the history data Da of the operation data D1 and not included in the history data Da of the reproduction data D2. In this example, the data acquisition unit 141 extracts an element representing an event A that occurred on February 25 and an element representing an event that occurred at an earlier time. The data acquisition unit 141 pulls back the measurement data Db by subtracting the element value of the measurement data Db of the reproduction data D2 from the element value of the measurement data Db of the operation data D1. In this example, the data acquisition unit 141 subtracts the number of activations 300 times in the reproduction data D2 from the number of activations 30300 in the operation data D1, and returns the measurement data Db to 30000 times. The data acquisition unit 141 transmits the reproduced operation data D1 to the operation data storage unit 142.

At the data acquisition time in this example, the history data Da of the operation data D1 has an element representing the event B that occurred on March 2. The history data Da of the reproduction data D2 has an element that represents an event B that occurred on March 2, and an element that represents an event that occurred at a time earlier than that. As described above, the number of elements of the history data Da of the reproduction data D2 is smaller than the number of elements of the history data Da of the operation data D1. In other words, the reproduction data D2, which is difference data, has fewer elements than the operation data D1 in which the storage capacity needs to be secured.

In the data acquisition time of this example, the value of the element indicating the number of activations of the measurement data Db of the operation data D1 is 30300 times. 30300 is an information amount of 15 bits or more as an unsigned integer. The value of the element indicating the number of activations of the measurement data Db of the reproduction data D2 is 300 times. 300 is an information amount of 9 bits or more as an unsigned integer. As described above, the number of bits necessary for expressing the measurement data Db of the reproduction data D2 is smaller than the number of bits required for expressing the measurement data Db of the operation data D1. In other words, the reproduction data D2, which is difference data, has fewer bits than the operation data D1 in which the storage capacity needs to be secured.

Thereafter, the generation unit 132 generates reproduction data based on the received state data. Thereafter, the second storage unit 133 updates the stored reproduction data based on the reproduction data received from the generation unit 132. Thereafter, the operation of the remote monitoring device 13 proceeds to step S302.

In step S302, the generation unit 132 determines whether the current time is the reporting period switching time. If the determination result is Yes, the operation of the remote monitoring device 13 proceeds to step S303. When the determination result is No, the operation of the remote monitoring device 13 proceeds to step S304.

In step S303, the generation unit 132 resets the reproduction data. Thereafter, the operation of the remote monitoring device 13 proceeds to step S304.

In step S304, the transmission unit 134 determines whether a data request signal has been received. When the determination result is No, the operation of the remote monitoring device 13 proceeds to step S301. If the determination result is Yes, the operation of the remote monitoring device 13 proceeds to step S305.

In step S305, the transmission unit 134 transmits the operation data and the reproduction data to the data acquisition device 14. Thereafter, the operation of the remote monitoring device 13 proceeds to step S301.
