Abstract

The objective of the invention is to solve the problem that even if processed resources are few, few data can be processed in a time delayed manner, e.g., when emergent sending or non-emergent sendingwhich is performed about emergent states of an elevator is suitable for different module structures. According to the invention, data is sent to a calling center from an elevator; at least one of a first module and a second module is used for processing data; an emergent state and a non-emergent state can be set; in a starting section of the non-emergent state, for the non-emergent setting, the first module and the second module are used for processing data; in the starting section of the emergent state, for the emergent setting, the first module is not used and the second module is used forprocessing the data; then, in the section suitable for the emergent setting, even if the emergent state is converted to be non-emergent state in the middle process, the method is continuously suitablefor emergent setting until the section is finished.

Description

technical field [0001] The present invention relates to a technique for switching a data communication method according to a situation. This concerns, for example, the transmission of data relating to the emergency state of the elevator when transmitting data between the elevator control unit and the call center. Background technique [0002] In order to maintain a plurality of elevators located in a long distance, relevant data is periodically collected on the elevator side, and the data is sent to a management department such as a call center for analysis and maintenance. The data can be, for example, detection data of various sensors, data generated by the device itself, voice input by elevator users and other data. The data is collected by the control unit, which is a small processor inside each elevator, and sent to the call center via WAN (wide-area network: Wide Area Network). [0003] In most cases, wireless technologies such as LTE (Long-Term-Evolution: Long-Term ...
