In this example, the collection unit 11 acquires the part data of the parts with the part priority of "high” every day. On the other hand, the collection unit 11 acquires the part data of the parts with the part priority "low” every ten days. Note that the part priority and the frequency of acquiring part data corresponding thereto may be three or more stages, or may be continuous values.
- the priority setting unit 10 may set the part priority based on the presence or absence of occurrence of abnormality for each part. At this time, the priority setting unit 10 sets the region priority “high” for the region determined to be “abnormal”. On the other hand, the priority setting unit 10 sets the part priority "low” for the part determined as "no abnormality”. Also, the priority setting unit 10 may set a criterion such as a threshold for the severity of an abnormality for determining that an abnormality has occurred. For example, the priority setting unit 10 may set the part priority based on whether or not an abnormality that makes it impossible to continue operation has occurred for each part.
- the collection unit 11 may combine the group priority and the part priority to control the acquisition of the driving data. For example, the acquisition unit selects a group from which driving data is to be acquired preferentially based on group priority. The acquisition unit preferentially acquires the part data of the part prioritized based on the part priority among the operation data of the elevators 2 included in the selected group. At this time, the collection unit 11 may stop acquiring part data for the elevators 2 included in the groups that were not selected based on the group priority, regardless of the part priority.
- the data acquisition system according to the present disclosure can be applied to acquire operation data from multiple elevators.
