The invention relates to the technical field of intelligent building elevator control, in particular to an off-line elevator calling control method based on edge service, comprising an elevator control system with cloud center service and local edge service, the off-line elevator calling control method comprises the following steps: S1, a user initiates an elevator calling request, s2, when the elevator control system is disconnected from the cloud center service, the working mode is switched to an offline mode; s3, the elevator control system carries out local right judgment; s4, the elevator control system inquires the authority information through the local edge service and verifies whether the user has the authority to access the target floor in combination with the floor information of the local database, and S5, the elevator control system determines the elevator calling type according to the elevator calling request and finally executes the elevator calling operation according to the elevator calling type. According to the invention, when the central service is not available, elevator operation such as elevator calling can still be completed, and normal use of the elevator system is ensured.

The application discloses an information processing method and device, electronic equipment and a computer readable medium, and relates to the technical field of mobile terminals. The method comprises the following steps: acquiring to-be-queried content and a plurality of first key information corresponding to the to-be-queried content; acquiring a historical query record, wherein the historical query record comprises at least one historical query content, each historical query content is corresponding to at least one second key information and a historical query result corresponding to the second key information; in the historical query record, finding the second key information matched with the first key information as target key information; and querying the reply content corresponding to the to-be-queried content based on the historical query result corresponding to the target key information and other key information. Therefore, the application can find the query result corresponding to part of the key information of the to-be-queried content in the historical query record, can reduce the query of part of the key information, and improves the query efficiency.
