and S4, judging whether a data transmission safety event occurs or not based on a data transmission log of the data center, and performing data inspection on the data transmission channel so as to determine whether to close the data transmission channel.
The beneficial effects of the technical scheme are as follows: the data center operation control method of the multi-user scene authenticates the user terminal, designates a data transmission channel with the data center to the user terminal with successful authentication, adjusts the use authority of the user terminal to the data transmission channel, and realizes that different user terminals access the data center independently at the same time; the data buffer space is also called as a transfer station for data access, and is used for completely storing the data required by the user terminal, so that the efficiency of returning the data to the user terminal is improved, and the access occupation time of the user terminal to the data center is effectively shortened; when the data center is in an overload connection state, the user terminal is authenticated secondarily, the connection mode of the user terminal is changed, the connection bandwidth resource of the data center is effectively released, and the data interaction efficiency with the user terminal is improved; and when a data transmission security event occurs, data checking is carried out on the data transmission channel, whether the data transmission channel is closed or not is determined, the user terminal is prevented from stealing tampered data, and the data security of the data center is ensured.
Preferably, in step S1, after authenticating a plurality of user terminals requesting connection, corresponding data transmission channels are designated to all user terminals that are authenticated successfully based on a network connection state of a data center; based on the real-time data state of the data transmission channel, adjusting the use authority of the user terminal to the corresponding data transmission channel comprises the following steps:
respectively extracting terminal identity information from connection requests from a plurality of user terminals, comparing the terminal identity information with a preset terminal list, and if the terminal identity information exists in the preset terminal list, successfully authenticating the user terminals; otherwise, the authentication of the user terminal fails;
designating corresponding data transmission channels to all user terminals which are successfully authenticated based on available gateways subordinate to a data center;
acquiring the data transmission rate of each data transmission channel within a preset time length range, and if the data transmission rate is greater than or equal to a preset rate threshold value, keeping the use authority of the user terminal on the corresponding data transmission channel unchanged; if the data transmission rate is smaller than the preset rate threshold, suspending the use permission of the user terminal to the corresponding data transmission channel.
The beneficial effects of the technical scheme are as follows: when a terminal such as a smart phone held by a user needs to access the data center to acquire corresponding data from the data center, the terminal held by the user needs to be connected to the data center, at the moment, the terminal held by the user initiates a connection request to the data center, after the data center receives the connection request, terminal identity information is extracted from the connection request, the terminal identity information is compared with a preset terminal list of the data center, whether the terminal held by the user belongs to an authenticated terminal is judged, and all the terminals which are authenticated successfully are marked. And then, based on the available gateway of the network where the data center is located and the gateways which are accessed by all the terminals with successful authentication at present in the network, designating corresponding data transmission channels for all the terminals with successful authentication, wherein each terminal with successful authentication has the most preferred use authority for designating the corresponding data transmission channel, thus ensuring that the terminals with successful authentication have the condition of independently accessing the data center and avoiding the occurrence of access crosstalk with other terminals. In addition, taking the data transmission rate of each data transmission channel within the preset time length range as a reference, if the data transmission rate is greater than or equal to a preset rate threshold value, the data transmission channel is indicated to be always kept in an active working state, namely the use permission of the user terminal on the data transmission channel is required to be continuously maintained, and the continuous access of the user terminal to the data center is ensured; if the data transmission rate is smaller than the preset rate threshold, the data transmission channel is in an idle state, at the moment, the use authority of the user terminal to the corresponding data transmission channel is suspended, the use authority of other user terminals to the data transmission channel is given, and the circulation use efficiency of the data transmission channel among different user terminals can be improved.
Preferably, in step S2, based on the data acquisition request of the user terminal, a data cache space is called in the data center, and the data obtained by searching from the data center is stored in the data cache space; based on the use authority of the user terminal to the data transmission channel, transferring the data from the data buffer space to the data transmission channel, comprising:

splitting the data searched from the data center, and then respectively storing the split data into a called data cache space;
when the user terminal has the use authority of the corresponding data transmission channel, the data is transferred from the data buffer space to the data transmission channel, so that the data is sent to the user terminal.

The data center is internally preset with a plurality of data caching spaces, each data caching space is used for caching data copies corresponding to data searched and located from the data center, all the data copies are transferred to a data transmission channel and further sent to a user terminal after searching and locating of all the data are completed, and the data caching spaces serve as data transfer stations of the data center, so that the data copies are uniformly sent only after searching and locating of all the data are completed, and the situation that data sending is disordered due to simultaneous searching and locating of the data and sending is avoided. The size of each data buffer space is limited, the requirement of caching all data in the whole search and positioning process is not necessarily met, at least one data buffer space in an idle state is called in a data center based on the data size of the data expected to be acquired, the total space of all called data buffer spaces is not smaller than the data size, therefore, the whole buffer of all data is guaranteed, the data obtained from the data center are split, and then are respectively stored in the called data buffer spaces, so that the data can be quickly transferred from the data buffer spaces to a data transmission channel, and the sending speed of the data to a user terminal is improved.
Preferably, in step S3, based on the current connection state of the user terminal of the data center, it is determined whether the data center is in an overload connection state; and when the data center is in the overload connection state, after performing secondary authentication on all the user terminals, changing the connection mode of the data center and the user terminals, including:

when the overload connection state is in, performing secondary authentication on all user terminals, and identifying active user terminals existing in the user terminals; the active user terminal refers to a user terminal which performs data interaction with the data center in real time; and disconnecting the connection relation between the data center and the inactive user terminal.
The beneficial effects of the technical scheme are as follows: the number of the user terminals currently connected with the data center is excessive, and the data transmission bandwidth of the data center cannot ensure that all the user terminals are subjected to timely and efficient data transmission. And judging whether the data center is in an overload connection state or not by taking the number of the user terminals currently connected with the data center as a reference, further carrying out secondary authentication on all the user terminals, and timely disconnecting the connection relation between the data center and the inactive user terminals so as to effectively release the data transmission bandwidth originally occupied by the inactive user terminals.
Preferably, in step S4, based on the data transmission log of the data center, determining whether a data transmission security event occurs, and performing data inspection on the data transmission channel to determine whether to close the data transmission channel, includes:
extracting a process record for transmitting data to a user terminal from a data transmission log of a data center, analyzing the process record, and judging whether a security event of abnormal data transmission flow occurs or not; if yes, carrying out data sampling inspection on the corresponding data transmission channel, and judging whether the data transmission channel is illegally hijacked; if the data is hijacked illegally, the corresponding data transmission channel is closed.
The beneficial effects of the technical scheme are as follows: extracting a process record of sending data to a user terminal from a data transmission log of a data center, identifying a data flow change condition in the process of sending the data to the user terminal from the process record, judging a security event with abnormal data transmission flow if the data flow change condition indicates that the data transmission flow is overlarge for the user terminal, at the moment, carrying out data sampling inspection on a corresponding data transmission channel, analyzing whether an illegal code exists in an acquired data sample, if so, indicating that the data transmission channel is illegally hijacked, at the moment, closing the corresponding data transmission channel, avoiding the data center from being swept, and effectively improving the data security of the data center.
