after the access control terminal accesses the network, the unique identifier of the access control terminal is bound to a background server, and communication connection between the access control terminal and the background server is established; then, the background server issues configuration items representing the opening states of mask detection, temperature detection and health code detection to the entrance guard terminal; each detection mode has a corresponding configuration item for determining the operating state of the different detection modes.
S105: and the access control terminal controls the opening or closing of the corresponding detection mode according to the configuration item, collects the characteristic information required by the detection mode in the opening state and carries out pass verification.
And after receiving the configuration information sent by the background server, the access control terminal controls the opening or closing of the corresponding detection mode according to each configuration item, collects the characteristic information required by the detection mode in the opening state and carries out pass verification. If three switches of gauze mask detection, temperature detection, health code detection all are in the on-state, then before carrying out the operation of opening the door, except conventional authentication, need detect these three conditions respectively, just can open the door after the three all satisfies preset condition.
In this embodiment, the entrance guard terminal and the mobile terminal interact with each other in a two-dimensional code manner, network configuration of the entrance guard terminal is completed and the entrance guard terminal is accessed to the background server, the background server issues different detection manners to the entrance guard terminal in a configuration item manner, and the entrance guard terminal can be applied to different use scenes by flexibly combining and configuring the detection manners of the entrance guard machine in the manner, so that various requirements are met. According to the scheme, the network configuration information of the access control terminal can be modified only through the mobile terminal, so that even if an engineering password is leaked, the network configuration of the access control machine can be checked only and cannot be modified, and the safety of the access control machine can be guaranteed.

S204: judging whether the acquired human body temperature is within a preset normal range, if so, comparing the human face characteristics with human face characteristic data stored locally in the access control terminal, and if matching is successful, entering the next step;
in a specific example, the background server issues a preset face recognition threshold value to the access control system, the access control system compares the face features with face feature data locally stored in the access control terminal, and if the matching degree between the face features and the face feature data is greater than the face recognition threshold value, the matching is considered to be successful;
s205: and acquiring the health code corresponding to the successfully compared face feature data from the background server, executing door opening operation if the health code is a green code, and ending the process and waiting for next frame data if the health code is not the green code.

It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
