  • step S011 the second response unit 43 posts a message to the interface indicating that the part is not in stock and including the estimated delivery time of the part.
  • step S010 After the operation of step S010 or step S011 is performed, the operation of step S012 is performed.
  • step S012 the first response unit 36 posts a message to the interface inquiring of the third response unit 53 about the third information, which is the contract information.
  • step S013 the third response unit 53 posts a message including the contract information as the third information to the interface.
  • the third response unit 53 posts a message including the contract expiration date for the elevator.
  • step S014 the first response unit 36 posts a message to the interface indicating instructions for the necessary maintenance work to the maintenance personnel based on the response message from the second response unit 43, the response message from the third response unit 53, and the work instruction information. Specifically, if the contract deadline is after the estimated delivery date, the first response unit 36 posts a message to the interface indicating instructions to replace parts that need to be replaced.
  • step S015 the operation of step S015 is performed.
  • the maintenance staff posts a message to the interface via the maintenance account AM to the effect that the maintenance work has been completed. That is, the access unit 23 receives input from the maintenance staff via the input unit 22 to the interface regarding the completion of the maintenance work. The input is reflected in the interface.
  • the message to the effect that the maintenance work has been completed may also include the contents of the final response.
  • step S016 the first response unit 36 notifies the outside of the content of the final response based on the content of the response.
  • the report creation unit 33 creates information for the work report.
  • the maintenance system 10 includes an interface unit 31, an access unit 23, a first response unit 36, and a second response unit 43.
  • the first response unit 36 posts a message to the interface inquiring of at least a part of the second information to the second response unit 43.
  • the second response unit 43 posts a message indicating the inquired content to the interface.
  • the first response unit 36 posts a message indicating maintenance work to the interface using at least a part of the second information posted to the interface by the second response unit 43.
  • the maintenance staff can read these exchanges in the interface. Therefore, the maintenance staff can know how and on what second information the maintenance work instruction was given. That is, the maintenance staff can easily know the relevance of the information provided.
  • the first response unit 36 and the second response unit 43 are realized by devices rather than people. In other words, responses to inquiries that have traditionally been performed by human operators can now be realized by devices. This makes it possible to reduce the resources required to respond to such inquiries. Furthermore, since maintenance work instructions can be issued regardless of the operator's own ability, it is possible to prevent errors in judgment and omissions due to lack of experience and resources of maintenance personnel and operators.
  • the second information is parts management information. If the inquired part is not in stock, the second response unit 43 posts a message to the interface to the effect that the part is not in stock and the estimated delivery date of the part. This makes it possible to reduce the process of inquiring about the estimated delivery date when the part is not in stock.
  • the maintenance system 10 further includes a third response unit 53.
  • the third response unit 53 posts a message indicating third information related to the contract details.
  • a work plan needs to be made based on the contract details of the elevator in question.
  • the first response unit 36 also posts a message to the interface indicating an instruction to replace the part based on the estimated delivery date included in the second information and the contract expiration date included in the third information. This makes it possible to prevent, for example, entering into a work plan with the contractor to replace the part after the contract expiration date.
  • the maintenance system 10 further includes a fourth response unit 63.
  • the fourth response unit 63 posts a message of the fourth information, which is information about the site. This allows workers to easily learn information about the site where maintenance work is being performed.
  • the fourth information also includes at least some of the comments left by maintenance personnel during previous elevator maintenance work.
  • the maintenance personnel performing the current maintenance work can easily see those comments.
  • the maintenance work can be carried out more efficiently, the cause of a malfunction can be discovered early, the equipment can be diagnosed with greater accuracy, and other benefits can be obtained.
  • the fourth response unit 63 also posts different information depending on the time period of the posting. For example, when posting in the first time period, information about entering the site in the second time period is unnecessary and potentially misleading, which is redundant information.
  • the fourth response unit 63 can suppress the posting of redundant information. As a result, the maintenance personnel can efficiently carry out maintenance work.
  • the maintenance system 10 also includes a report creation unit 33.
  • An important element of maintenance work is that the maintenance worker performs the work correctly on-site based on appropriate judgment.
  • a work report is a document in which it is important that such elements are properly recorded.
  • the report creation unit 33 reflects the message in the work report using a device, thereby preventing mistakes such as omissions in the work report. It is also possible to reduce the amount of work that the maintenance worker has to do to write up the work report.
  • the departments that update and manage the work instruction information, second information, third information, and fourth information may be separate.
  • the task of updating information is prevented from being concentrated in one department, and maintenance of each piece of information can be performed frequently.
  • the amount of learning required for each model can be reduced.
