Detailed Description

Embodiments of an object for implementing the present invention will be described with reference to the accompanying drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and repetitive description thereof will be appropriately simplified or omitted. The object of the present invention is not limited to the following embodiments, and modifications of any of the constituent elements of the embodiments or omission of any of the constituent elements of the embodiments can be made without departing from the spirit of the present invention.

Embodiment 1

Fig. 1 is a block diagram of a data acquisition system 1 according to embodiment 1.

The data acquisition system 1 is applied to a system including a plurality of elevators 2, for example. The elevator 2 is an example of a hoist. The data acquisition system 1 is a system that acquires information of a plurality of elevators such as the elevator 2 as information used for monitoring from a remote place or the like, for example. The data acquisition system 1 is, for example, a remote monitoring system or the like.

Each elevator 2 is applied to a building having a plurality of floors, for example. The plurality of elevators 2 may include elevators 2 applied to the same building. Each elevator 2 includes a car, not shown, for transporting a user between a plurality of floors, a hoisting machine, not shown, for driving the car, and the like. The car is provided with a door, not shown, which divides the interior and exterior of the car. A brake, not shown, for braking travel of the car is provided for the hoisting machine. The elevator 2 includes a plurality of locations. The plurality of portions of the elevator 2 include, for example, a hoisting machine, a door, a brake, and the like.

Each elevator 2 is provided with a control device 3. The control device 3 is a device that controls the operation of the elevator 2, such as car running. The control device 3 collects information from various locations and the like of the elevator 2 so that the operation of the elevator 2 can be controlled. The information collected here includes, for example, a measurement signal of a sensor or the like, a detection signal of a switch or the like, an image signal of an imaging device or the like, a sound signal of a microphone or the like, a control signal of an apparatus including these components, and the like. The sensor, the switch, the imaging device, the microphone, or the like is provided in, for example, the elevator 2 or an accessory device of the elevator 2 or a peripheral device, or the like.

Each elevator 2 is classified into any one of a plurality of groups set in advance. The plurality of groups are groups obtained by classifying the elevators 2 according to specifications, for example. The specification information of the elevator 2 includes information such as a model, a rated speed, and a transport capacity.

The data acquisition system 1 includes a plurality of remote monitoring devices 4 and a central management device 5.

Each remote monitoring device 4 corresponds to an arbitrary elevator 2. The remote monitoring device 4 is disposed in the same building as the building to which the corresponding elevator 2 is applied, for example. The remote monitoring device 4 is used to monitor the state of the corresponding elevator 2 from a remote place, and the like. The remote monitoring device 4 is connected to the control device 3 and the like so that the status information of the corresponding elevator 2 can be acquired. The remote monitoring device 4 stores the acquired status information of the elevator 2. The information stored here contains operation data indicating the operation state of the elevator 2. The remote monitoring device 4 may accumulate the operation data of the elevator 2 as the location data related to each location included in the elevator 2. The remote monitoring device 4 is connected to the central management device 5 through a communication network such as the internet or a telephone line network so as to be able to transmit information acquired by operation data or the like.

Each remote monitoring device 4 determines occurrence of an abnormality in the corresponding elevator 2 based on information acquired from the control device 3 or the like of the elevator 2. In this example, the abnormality occurring in the elevator 2 refers to an abnormal event among events occurring in the elevator 2. The abnormality of the elevator 2 contains, for example, symptoms and faults. The sign is, for example, an event in which the observed data deviates from a predetermined normal range. A fault is for example an event in which the operation of the elevator 2 creates some kind of obstacle. The failure may include a failure in which the elevator 2 can continue to operate, a failure in which the elevator can continue to operate under the conditions such as the accompanying traveling speed or traveling range, a failure in which the elevator cannot continue to operate, and the like. When it is determined that an abnormality has occurred, the remote monitoring device 4 stores information of the abnormality, for example. Alternatively, the remote monitoring device 4 may report the occurrence of the abnormality to the central management device 5 or the like, for example, when it is determined that the degree of emergency of the occurrence of the abnormality is high. The remote monitoring device 4 may determine occurrence of an abnormality in the corresponding elevator 2 as a site abnormality for each site included in the elevator 2.

The central management device 5 is a device for managing the status information of the elevator 2 acquired by the data acquisition system 1. Some or all of the functions of the central management device 5 are mounted on one or more server devices disposed at a site such as an information center, for example. The information center is a point where information of the elevators 2 monitored by the data acquisition system 1 is collected. Alternatively, part or all of the functions of the central management device 5 may be mounted on one or more server devices or the like disposed outside the information center. Some or all of the functions of the central management device 5 may be installed by a storage resource, a processing resource, or the like on the cloud service. The central management device 5 includes a specification information storage unit 6, a monitoring unit 7, an abnormality history storage unit 8, a report history storage unit 9, a priority setting unit 10, a collection unit 11, an operation data storage unit 12, and an analysis unit 13.

The specification information storage 6 stores information such as specifications of each elevator 2. The specification information storage 6 stores information of groups into which the elevators 2 are classified.

The monitoring unit 7 is a part having a function of acquiring abnormality information from each elevator 2. The monitor 7 includes a periodic monitor 14 and a report monitor 15.

The periodic monitoring unit 14 is a part having a function of periodically acquiring abnormality information stored in each remote monitoring device 4. The frequency of acquiring the abnormality information by the periodic monitoring unit 14 is, for example, once every month. The periodic monitoring unit 14 transmits an instruction to transmit the stored abnormality information to the remote monitoring device 4 at the timing of acquiring the abnormality information. The remote monitoring device 4 that received the instruction transmits the accumulated abnormality information to the central management device 5. Here, if there is no stored abnormality information, the remote monitoring device 4 that has received the command may transmit the information indicating that there is no abnormality information to the central management device 5. The abnormality information acquired from the plurality of elevators 2 by the periodic monitoring unit 14 is stored in the abnormality history storage unit 8.

The report monitor 15 is a part having a function of receiving a report indicating occurrence of an abnormality from each remote monitoring device 4 as the abnormality information. The report monitor 15 stores the abnormality information acquired from the plurality of elevators 2 by reporting in the report history storage 9.

The priority setting unit 10 is a unit having a function of setting priority based on abnormality information acquired from the plurality of elevators 2 by the monitoring unit 7. The priorities set by the priority setting unit 10 include group priorities set for each group into which each elevator 2 is classified. The priority setting unit 10 sets the group priority to be higher as the number of groups in which abnormality occurs increases. For example, the priority setting unit 10 refers to the information stored in the specification information storage unit 6, the abnormality history storage unit 8, or the report history storage unit 9, and counts the number of abnormalities occurring in the elevators 2 classified into groups for each group. The priority setting unit 10 sets the group priority of each group using a monotonically increasing function or the like for the counted number of abnormal occurrences.

The collection unit 11 is a part having a function of acquiring operation data stored in the remote monitoring device 4 corresponding to each elevator 2 from the remote monitoring device 4 according to the priority set by the priority setting unit 10. The operation data acquired by the collection unit 11 includes detailed information such as a change in the traveling speed of the car or time-series data of a change in the opening/closing position of the car. The collection unit 11 stores the operation data acquired from the plurality of elevators 2 in the operation data storage unit 12. The collection unit 11 obtains operation data at a frequency set in advance, for example. In this example, the collection unit 11 acquires operation data at a predetermined regular timing, for example.

The collection unit 11 selects a group to be the object of acquiring the operation data, for example, based on the group priority. The collection unit 11 is preset with a group threshold value related to the group priority. The collection unit 11 acquires operation data from the elevators 2 included in the group having the group priority higher than the group threshold. On the other hand, the collection unit 11 stops acquiring the operation data from the elevators 2 included in the group whose group priority is lower than the group threshold.

The analysis unit 13 is a part having a function of analyzing the state of the elevator 2 or the like based on the operation data stored in the operation data storage unit 12. The analysis unit 13 analyzes the stored operation data as, for example, big data. The analysis unit 13 calculates, for example, an appropriate time interval for the maintenance spot inspection work of each elevator 2. The analysis unit 13 detects, for example, a sign that abnormality is to occur in each elevator 2. The analysis unit 13 may perform these analyses for each group into which each elevator 2 is classified. The maintenance spot inspection work in each elevator 2 is performed using the result of the analysis performed by the analysis unit 13. The analysis performed by the analysis unit 13 is referred to by a maintenance person who performs maintenance spot inspection work, for example, by a terminal device such as a maintenance terminal. By the analysis unit 13, for example, the maintenance spot inspection operation can be performed efficiently, and the occurrence of abnormality such as a failure can be prevented.

Next, an example of the priority set in the data acquisition system 1 will be described with reference to fig. 2.

Fig. 2 is a diagram showing an example of priorities set in the data acquisition system 1 according to embodiment 1.

The abnormality information of the elevator 2 for priority setting is counted for each group based on the information stored in the abnormality history storage unit 8 or the report history storage unit 9. Unique group IDs (IDs) are assigned to the respective groups. Here, the group IDs are sequentially given from 1 up to an integer N representing the total number of groups. Each group is classified according to specification information such as model, rated speed, and transport capacity. The priority setting unit 10 compares the number of abnormal occurrences, the occurrence rate of abnormal occurrences, and the like with a preset threshold value for each group. The priority setting unit 10 sets a group priority "high" for a group in which abnormality occurs more than a threshold. The priority setting unit 10 sets a group priority "low" for a group whose occurrence of an abnormality is equal to or lower than a threshold.

The group threshold is set between group priority "high" and group priority "low". That is, the collection unit 11 acquires operation data from the elevators 2 included in the group having the "high" group priority. Here, the group may include the elevator 2 in which no abnormality has occurred. On the other hand, the collection unit 11 stops acquiring operation data from the elevator 2 included in the group having the "low" group priority.

The priority setting in the priority setting unit 10 is performed, for example, before the timing of acquiring the operation data. The priority setting in the priority setting unit 10 may be performed, for example, at the timing when the monitoring unit 7 acquires the abnormality information from the elevator 2.

Next, an operation example of the data acquisition system 1 will be described with reference to fig. 3.

Fig. 3 is a flowchart showing an example of the operation of the data acquisition system 1 according to embodiment 1.

In step S11, the collection unit 11 determines whether or not it is time to acquire operation data. If the determination result is no, the process of the data acquisition system 1 proceeds to step S11 again. If the determination result is yes, the process of the data acquisition system 1 proceeds to step S12.

In step S12, the collection unit 11 sets a group whose group ID is 1 as a processing target. Then, the processing of the data acquisition system 1 advances to step S13.

In step S13, the collection unit 11 determines whether or not the group priority set for the group to be processed is equal to or greater than the group threshold. If the determination result is yes, the process of the data acquisition system 1 proceeds to step S14. If the determination result is no, the process of the data acquisition system 1 advances to step S15.

In step S14, the collection unit 11 acquires operation data from the elevators 2 included in the group to be processed. The collection unit 11 sequentially transmits, for example, an instruction requesting transmission of operation data to the remote monitoring devices 4 of the elevators 2 included in the group. The collection unit 11 obtains operation data of the elevator 2 corresponding to the remote monitoring device 4 from the remote monitoring device 4 that received the instruction. Then, the processing of the data acquisition system 1 advances to step S15.

In step S15, the collection unit 11 determines whether or not the group ID of the group to be processed reaches an integer N, which is the total number of groups. If the determination result is no, the process of the data acquisition system 1 proceeds to step S16. If the determination result is yes, the data acquisition processing in the data acquisition system 1 ends.

In step S16, the collection unit 11 adds 1 to the group ID of the current processing target group. The collection unit 11 sets a group to which a group ID obtained by adding 1 is added as the next processing target. Then, the processing of the data acquisition system 1 advances to step S13.

As described above, the data acquisition system 1 according to embodiment 1 includes the monitor 7 and the collection unit 11. In the data acquisition system 1, each elevator 2 is classified into at least one set in advance. The monitoring unit 7 obtains abnormality information from each elevator 2. The collection unit 11 obtains operation data indicating the operation status of each elevator 2 more preferentially from the elevators 2 included in the group having higher group priority. The group priority is set based on the abnormality information acquired by the monitor 7.

According to this configuration, the acquisition of the operation data is controlled in accordance with the priority set such as the group priority, and thus, the acquisition of unnecessary operation data can be suppressed. Therefore, the shortage of communication capacity due to the data acquired from the elevator 2 can be suppressed. This can suppress an increase in communication cost and the like associated with an increase in communication traffic. Further, by suppressing the traffic volume, the proportion of the communication path occupied by the communication of the operation data can be suppressed. Further, since the capacity itself of the collected data can be suppressed, the storage capacity of the operation data storage unit 12 or the like that stores the operation data can also be suppressed. In addition, the occurrence of an abnormality or the like differs depending on the group classified based on the specification or the like of the elevator 2. The data acquisition system 1 restricts acquisition of operation data for each group based on abnormality information for each group. Thus, the data acquisition system 1 can control the acquisition of the operation data even for an elevator 2 whose occurrence of an abnormal situation is unknown, such as a newly installed elevator 2, based on the occurrence of the abnormal situation of the same type of elevator 2.

Further, the group priority is set to be higher as the number of groups in which abnormality occurs increases.

According to this configuration, since the operation data is obtained with emphasis on the group in which the occurrence of abnormality is large, the accuracy of analysis based on the operation data for the elevators 2 included in the group is further improved. Therefore, maintenance spot inspection work can be more efficiently performed for these elevators 2, and occurrence of abnormality such as failure can be more effectively prevented. The data acquisition system 1 can also be configured to acquire operation data with emphasis on the elevator 2 in which no abnormality has occurred, based on the situation in which an abnormality has occurred in the same type of elevator 2.

The collection unit 11 also stops acquiring operation data from the elevators 2 included in the group having the group priority lower than the preset group threshold.

With this configuration, the data acquisition system 1 can more concentrate communication resources, storage resources, and the like on acquiring operation data from the elevator 2 included in the group to which the higher priority is set.

The collecting unit 11 may acquire the operation data from the elevators 2 included in the group whose group priority is set to be higher at a higher frequency. For example, the collection unit 11 may acquire the operation data for a group having a group priority "high" at a higher frequency than a group having a group priority "low". In this example, the collection unit 11 obtains operation data from the elevators 2 included in the group having the "high" group priority every day. On the other hand, the collection unit 11 acquires operation data every ten days from the elevators 2 included in the group having the "low" group priority. The group priority and the frequency of acquiring the operation data corresponding thereto may be three or more levels, or may be continuous values.

The priority setting unit 10 may set the group priority according to whether or not an abnormality has occurred for each group. At this time, the priority setting unit 10 sets a group priority "high" for the group determined to be "abnormal". On the other hand, the priority setting unit 10 sets a group priority "low" for a group determined to be "no abnormality". The priority setting unit 10 may set a criterion such as a threshold value for the degree of severity of the abnormality determined to be abnormal. For example, the priority setting unit 10 may set the group priority according to whether or not an abnormality occurs in each group, which makes it impossible to continue operation.

The data acquisition system 1 may be applied to acquiring operation data from an elevator such as an escalator.

Next, an example of a hardware configuration of the data acquisition system 1 will be described with reference to fig. 4.

Fig. 4 is a hardware configuration diagram of a main part of the data acquisition system 1 according to embodiment 1.

Each function of the processing in the data acquisition system 1 can be realized by a processing circuit. The processing circuit is provided with at least one processor 100a and at least one memory 100b. The processing circuit may include the processor 100a, the memory 100b, and at least one dedicated hardware 200, or the processing circuit may include at least one dedicated hardware 200 instead of the processor 100a and the memory 100b.

In the case where the processing circuit includes the processor 100a and the memory 100b, each function of the data acquisition system 1 is realized by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. The program is stored in the memory 100b. The processor 100a reads out and executes a program stored in the memory 100b to realize the functions of the data acquisition system 1.

The processor 100a is also called a CPU (Central Processing Unit: central processing unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The Memory 100b is constituted by a nonvolatile or volatile semiconductor Memory such as RAM (Random Access Memory: random access Memory), ROM (Read Only Memory), flash Memory, EPROM (Erasable Programmable Read Only Memory: erasable programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory: electrically erasable programmable Read Only Memory), or the like.

In the case of a processing circuit provided with dedicated hardware 200, the processing circuit is implemented, for example, by a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit: application specific integrated circuit), an FPGA (Field Programmable Gate Array: field programmable gate array), or a combination thereof.

Each function of the processing in the data acquisition system 1 can be realized by a processing circuit. Alternatively, the functions of the data acquisition system 1 may be realized by a processing circuit. The functions of the data acquisition system 1 may be implemented in part by dedicated hardware 200, and in other parts by software or firmware. In this way, the processing circuit realizes the respective functions of the data acquisition system 1 by dedicated hardware 200, software, firmware, or a combination thereof.

Embodiment 2

In embodiment 2, differences from the example disclosed in embodiment 1 will be described in particular detail. As for the features not described in embodiment 2, any features of the examples disclosed in embodiment 1 may be employed.

The specification information storage unit 6 of embodiment 2 stores information on the locations included in each elevator 2.

The monitoring unit 7 obtains the site abnormality information of each site included in the elevator 2 from each elevator 2. The site abnormality information is included in abnormality information or the like acquired from each elevator 2 by the periodic monitoring unit 14. The site abnormality information is included in report information or the like received by the report monitor 15 from each remote monitoring device 4.

The priority setting unit 10 sets priority based on the abnormality information of the part obtained by the monitoring unit 7 from the plurality of elevators 2. The priority set by the priority setting unit 10 includes a site priority set for each site included in at least one of the elevators 2. The priority setting unit 10 sets the site priority to be higher as the number of sites in which abnormality occurs increases. For example, the priority setting unit 10 refers to the information stored in the specification information storage unit 6, the abnormality history storage unit 8, or the report history storage unit 9, and counts the number of abnormalities occurring in each elevator 2 for each location. The priority setting unit 10 sets the part priority of each part by using a monotonically increasing function or the like for the counted number of abnormal occurrences.

The collection unit 11 obtains the location data of each location stored in the remote monitoring device 4 from the remote monitoring device 4 corresponding to each elevator 2 according to the priority set by the priority setting unit 10. The collecting unit 11 stores the position data acquired from the plurality of elevators 2 in the operation data storage unit 12. The collection unit 11 acquires the location data at a frequency set in advance, for example.

The collection unit 11 selects a site to be a target of acquiring site data, for example, based on the site priority. The collection unit 11 is provided with a site threshold value related to a site priority in advance. The collection unit 11 acquires, from each elevator 2, location data relating to a location having a location priority higher than a location threshold. On the other hand, the collection unit 11 stops acquiring the location data on the locations having the location priority lower than the location threshold value from each of the elevators 2.

The analysis unit 13 analyzes the state and the like of each location of the elevator 2 based on the location data stored in the operation data storage unit 12. The analysis unit 13 analyzes the accumulated site data as, for example, big data.

Fig. 5 is a diagram showing an example of priorities set in the data acquisition system 1 according to embodiment 2.

The abnormality information of the elevator 2 for priority setting is counted for each location based on the information stored in the abnormality history storage unit 8 or the report history storage unit 9. Each site is assigned a unique site ID. Here, the site ID is given sequentially from 1 to an integer n indicating the total number of types of sites. The plurality of locations include, for example, a hoisting machine, a brake, a door, and the like. The plurality of sites may be sites higher than or lower than the sites containing them. The priority setting unit 10 compares the number of abnormal occurrences, the occurrence rate of abnormal occurrences, and the like with a preset threshold value for each part. The priority setting unit 10 sets a part priority "high" for a part where abnormality occurs more than a threshold value. The priority setting unit 10 sets a part priority "low" for a part where the abnormality occurs below the threshold.

The site threshold is set between a site priority "high" and a site priority "low". That is, the collection unit 11 acquires the location data on the location with the "high" location priority from each elevator 2. In this case, information may be acquired from the elevator 2 in which no abnormality has occurred at the location. On the other hand, the collection unit 11 stops acquiring the part data concerning the part of which the part priority is "low".

The priority setting in the priority setting unit 10 is performed, for example, before the timing of acquiring the site data. The priority setting in the priority setting unit 10 may be performed, for example, at the timing when the monitoring unit 7 acquires the site abnormality information from the elevator 2.

Next, an operation example of the data acquisition system 1 will be described with reference to fig. 6.

Fig. 6 is a flowchart showing an example of the operation of the data acquisition system 1 according to embodiment 2.

In step S21, the collection unit 11 determines whether or not it is a timing to acquire the part data. If the determination result is no, the process of the data acquisition system 1 proceeds to step S21 again. If the determination result is yes, the process of the data acquisition system 1 proceeds to step S22.

In step S22, the collection unit 11 sets a portion having a portion ID of 1 as a processing target. Then, the processing of the data acquisition system 1 advances to step S23.

In step S23, the collection unit 11 determines whether or not the site priority set for the site to be processed is equal to or greater than the site threshold. If the determination result is yes, the process of the data acquisition system 1 proceeds to step S24. If the determination result is no, the process of the data acquisition system 1 advances to step S25.

In step S24, the collecting unit 11 acquires, from each of the elevators 2, location data related to the location to be processed. The collection unit 11 sequentially transmits, for example, a command requesting transmission of the location data of the location to the remote monitoring device 4 of the elevator 2 including the location. The collection unit 11 acquires the site data of the site from the remote monitoring device 4 that received the instruction. Then, the processing of the data acquisition system 1 advances to step S25.

In step S25, the collection unit 11 determines whether or not the part ID of the part to be processed has reached an integer n, which is the total number of types of parts. If the determination result is no, the process of the data acquisition system 1 proceeds to step S26. If the determination result is yes, the data acquisition processing in the data acquisition system 1 ends.

In step S26, the collection unit 11 adds 1 to the part ID of the current processing target part. The collection unit 11 sets the portion to which the portion ID obtained by adding 1 is added as the next processing target. Then, the processing of the data acquisition system 1 advances to step S23.

As described above, the data processing system according to embodiment 2 includes the monitor unit 7 and the collection unit 11. The monitoring unit 7 obtains site abnormality information for each site included in at least one of the elevators 2. The collection unit 11 obtains the site data related to each site more preferentially from the site with higher site priority. The site priority is set based on the site abnormality information acquired by the monitor 7.

According to this configuration, the location where the operation data is acquired is controlled based on the priority set such as the location priority, and thus, useless acquisition of the operation data can be suppressed. Therefore, the shortage of communication capacity due to the data acquired from the elevator 2 can be suppressed. This can suppress an increase in communication cost and the like associated with an increase in communication traffic. Further, by suppressing the traffic volume, the proportion of the communication path occupied by the communication of the operation data can be suppressed. Further, since the capacity itself of the collected data can be suppressed, the storage capacity of the operation data storage unit 12 or the like that stores the operation data can also be suppressed. In addition, the situation such as occurrence of a site abnormality differs for each site of the elevator 2. The data acquisition system 1 restricts acquisition of the part data in the operation data based on the part abnormality information of each part. Thus, the data acquisition system 1 can control the acquisition of the location data in accordance with the situation of the occurrence of the abnormality of the location of the other elevator 2 even for the elevator 2 where the situation of the occurrence of the abnormality of each location of the newly installed elevator 2 is unknown, for example.

The site priority is set so that the more sites that are abnormal, the higher the site priority.

According to this configuration, since the site data is obtained with emphasis on the sites where the occurrence of the abnormality is large, the accuracy of analysis for these sites is further improved. Therefore, the maintenance spot inspection work can be more efficiently performed for the elevator 2 including these portions, and the occurrence of abnormality such as a failure can be more effectively prevented. The data acquisition system 1 can also be configured to be capable of acquiring operation data concerning a necessary location with respect to an elevator 2 in which no abnormality has occurred, based on a situation in which a location abnormality has occurred in another elevator 2.

The collection unit 11 also stops acquiring the part data of the part whose part priority is lower than the part threshold set in advance.

With this configuration, the data acquisition system 1 can concentrate communication resources, storage resources, and the like on acquisition of location data related to a location for which a higher priority is set.

The collection unit 11 may acquire the part data of the part whose part priority is set to be higher at a higher frequency. For example, the collection unit 11 may acquire the part data for a part having a part priority "high" with a frequency higher than that of a part having a part priority "low". In this example, the collection unit 11 acquires the site data of the site having the site priority "high" every day. On the other hand, the collection unit 11 acquires the site data of the site having the site priority "low" every ten days. The site priority and the frequency of acquiring the site data corresponding thereto may be three or more levels, or may be continuous values.

The priority setting unit 10 may set the site priority according to whether or not abnormality occurs in each site. At this time, the priority setting unit 10 sets a part priority "high" for the part determined to be "abnormal". On the other hand, the priority setting unit 10 sets a part priority "low" for a part determined to be "no abnormality". The priority setting unit 10 may set a criterion such as a threshold value for the degree of severity of the abnormality determined to be abnormal. For example, the priority setting unit 10 may set the site priority according to whether or not abnormality occurs in each site, which makes it impossible to continue operation.

The collection unit 11 may control the acquisition of the operation data by combining the group priority and the site priority. For example, the acquisition unit selects a group that preferentially acquires the operation data according to the group priority. The acquisition unit preferentially acquires data from the part data of the part, which is prioritized according to the part priority, among the operation data of the elevators 2 included in the selected group. In this case, the collection unit 11 may stop acquiring the location data for the elevators 2 included in the group not selected according to the group priority regardless of the location priority.

In this way, by screening the elevator 2 that acquires the location data according to the group priority, the amount of the acquired operation data can be further suppressed. This can further suppress the acquisition of unnecessary operation data.

Industrial applicability

The data acquisition system of the present invention can be applied to acquiring operation data from a plurality of elevators.
