generating, by a server, setting information, which comprises route information and open factor information, wherein the route information is configured to indicate a path of a secure conveying device, and wherein the open factor information is configured to indicate a condition for opening the secure conveying device;

transmitting, by the server, the open factor information to the secure conveying device, wherein the open factor information comprises a time factor, a position factor, and an authorization verification factor;

receiving, by the secure conveying device, the open factor information; setting, by the secure conveying device, an open time based on the time factor; setting, by the secure conveying device, an open position based on the position factor; and setting, by the secure conveying device, an open authorization condition based on the authorization verification factor;

positioning, by the server, the secure conveying device continuously; determining, by the server, continuously whether the path of the secure conveying device conforms to the route information; transmitting, by the server in response to the path of the secure conveying device not conforming to the route information, locking information to the secure conveying device; receiving, by the secure conveying device, the locking information; and locking, by the secure conveying device, the secure conveying device;

determining, by the secure conveying device, continuously whether a distance between the secure conveying device and an accompanying person conforms to a predetermined range; and locking, by the secure conveying device in response to the distance not conforming to the predetermined range, the secure conveying device;

receiving, by the secure conveying device, authorization information, in response to the server determining no occurrence of the path of the secure conveying device not conforming to the route information and the secure conveying device determining no occurrence of the distance between the secure conveying device and the accompanying person not conforming to the predetermined range; verifying, by the secure conveying device, the authorization information; determining, by the secure conveying device, whether position information of the secure conveying device at a time of receiving the authorization information conforms to the position factor; and determining, by the secure conveying device, whether the time of receiving the authorization information conforms to the time factor, wherein the authorization information comprises at least two pieces of authorization sub-information;

performing, by the secure conveying device, an open operation, after determining that the at least two pieces of authorization sub-information pass verification, the position information of the secure conveying device at the time of receiving the authorization information conforms to the position factor, and the time of receiving the authorization information conforms to the time factor; otherwise, locking, by the secure conveying device, the secure conveying device; and

receiving, by the secure conveying device before performing the open operation, connection request information from a to-be-connected device; and determining, by the secure conveying device, record information, wherein the record information comprises a time of receiving the connection request information, position information of the secure conveying device at the time of receiving the connection request information, and identification information of the to-be-connected device.
