Therefore, a communication method needs to be designed to coordinate thousands of intelligent terminals in an intelligent cell and realize cell biometric management without a high-performance server and a trawl.
Therefore, the technical problem actually solved by the present invention is how to adjust the communication process of the comparison of the biometric data.
As an illustrative example in the present embodiment, as shown in fig. 1, a communication method with a large-capacity biometric smart cell provides a central host, a plurality of partition hosts connected with the central host in a tree form, and a plurality of smart terminals connected with the partition hosts in a tree form, and the central host, the partition hosts, and the smart terminals all have independent storage devices and comparison devices; the communication method comprises the following steps:
step S1: acquiring biological characteristic data through a central host, a partition host or an intelligent terminal;
the central host is a first-level device, the partition host is a next-level device of the central host, namely a second-level device, and the intelligent terminal is a next-level device of the partition host, namely a third-level device.
The central host, the partition host and the intelligent terminal all store part of biological identification data.
Step S21: when the central host acquires the biological characteristic data, broadcasting the biological characteristic data, and completing characteristic comparison through the corresponding intelligent terminal;

In the communication method in this embodiment, through the central host, the partition host, and the intelligent terminal, which are arranged in a multi-layer hierarchical manner, and the central host, the partition host, and the intelligent terminal are set to be capable of acquiring and comparing biometric data, the comparison process is completed through the corresponding intelligent terminal device, and the storage of the biometric data is dispersed to the central host, the partition host, or the intelligent terminal, so that the storage pressure on the biometric data is reduced, the application cost is reduced, and the device to which the communication method is applied can operate without depending on a high-performance device.

completing feature comparison through the intelligent terminal and sending comparison result information;
and receiving the comparison result information by the central host computer and judging whether the biological characteristics are successfully compared.
When the central host computer is used for carrying out biological identification, biological characteristics enter through a biological identification processing program inlet and generate biological characteristic data, the biological characteristic data are broadcasted and sent to all intelligent terminals, the intelligent terminals finish comparison, if the intelligent terminals which store the biological characteristic data respond, the comparison is successful, before the intelligent terminals finish the characteristic comparison, a waiting timer is set, whether comparison result information is successful or not is judged through the waiting timer, if the identification is successful, the entrance guard opening operation is executed, if the identification is unsuccessful, the comparison is regarded as unsuccessful, and the operation is ended.
The waiting timer is set for the purpose of retransmitting data by the intelligent terminal under the current condition that the comparison information result is unsuccessful or fails in data transmission, if the central host waits for the response of the intelligent terminal after the transmission is finished and does not respond within the specified time, the comparison is judged to fail and the biological characteristic data of the user does not pass.

When the partition host is used for biological identification, biological characteristics enter through a biological identification processing program inlet, biological characteristic data is generated, and the biological characteristic data is broadcasted.
If the biological characteristic data is the biological characteristic data of the local partition host, the partition host broadcasts the biological characteristic data to each intelligent terminal in communication connection with the partition host.
If the biological characteristic data is not the biological characteristic data of the local machine of the partition host, the partition host uploads the biological characteristic data to the central host, the host broadcasts the biological characteristic data to each intelligent terminal, and the intelligent terminals complete comparison to enable the intelligent terminals storing the biological characteristic data to respond.
In addition, in the current step, broadcast data of the biological identification characteristics of the central host computer is not processed and is transmitted to each intelligent terminal connected with the partition host computer, and the successful response data of the intelligent terminal is superimposed with the serial number of the partition host computer and is transmitted to the central host computer.
