In the invention, the software function carrier of the visitor request input part can be mobile phone app, applet or H5 page, and the prior registration mode of the visitor comprises but is not limited to autonomous code scanning registration, manager registration and the like.
In the step 1 of the invention, the visitor has no knowledge about the park or community as the interviewee, so that the interviewee is verified by the owner after sending the access request, and the interviewee is corrected when the access request is problematic, thereby ensuring the correct access request and simultaneously playing the role of reminding the interviewee.
And 2, the server acquires the related access control equipment number and public key information thereof based on the visitor information, encrypts the visitor information by using the public key information and the visitor passing instruction, and converts the visitor information into binary codes to obtain a first optical sequence.
The step 2 comprises the following steps:
Step 2.1, inquiring the number of the access control equipment in an owner information association table preset by a server by taking the owner information as a retrieval element, and searching corresponding public key information in the preset access control equipment association table based on the number of the access control equipment;
Step 2.2, after primary encryption is carried out on the visitor information by using the public key information, secondary encryption is carried out on the visitor information through a visitor passing instruction, and an encrypted visitor sequence is obtained;
And 2.3, converting the encrypted visitor sequence into binary codes to obtain a first light sequence.
In the step 2.2 of the invention, the encryption algorithm of the primary encryption is a hash algorithm, and a hash value is obtained; the secondary encryption is to divide the hash value by the guest pass instruction. Here, the guest instruction is generally a decimal sequence, and the hash value obtained by hash calculation is a hexadecimal sequence, and the hexadecimal sequence needs to be converted into decimal in the process of secondary encryption and then divided.
In step 2.3 of the present invention, the encrypted guest sequence is a decimal sequence, which then needs to be converted into a binary sequence, thereby facilitating the emission of an optical signal.
And step 3, the server sends the visitor information to the corresponding access control equipment to update a visitor information list preset in the access control equipment, and sends the access control equipment number and the first optical sequence to the visitor terminal.
In step 3 of the invention, each access control device stores a corresponding visitor information list for storing all visitor information of the access control device, and after receiving the visitor information in the server, the access control device stores the visitor information in the visitor information list.

and 5.5, judging whether the current time is within the access time or not based on the consistent visitor information in the visitor information list, if so, releasing, otherwise, not releasing.
In step 5.1 of the present invention, each optical sequence sent by the mobile phone end needs to follow a set of optical communication protocol, so as to increase fault tolerance and environmental light interference resistance. Protocol rules: the long light of Ams is sent to represent the initial signal, then binary data bits are sent, the lamp Bms is turned off by default before each data bit is sent, and then if the lamp Cms is turned on, binary '0' is sent; if the light Dms is on, a binary "1" is sent, and then one parity bit is sent after the E-bit data bit is sent. Each 4-bit binary number corresponds to one-bit decimal number, and in total, E-bit binary data is transmitted, and then the E/4-bit decimal password is corresponding. A. B, C, D, E parameters can be freely configured to meet different requirements, and the invention is not limited and only provides protocol rules.
In step 5.2 of the present invention, the first optical sequence and the second optical sequence are multiplied to obtain the visitor information encrypted by the public key information.
In step 5.3 of the invention, the private key information is private key information of the access control equipment, the visitor information in the visitor information list is sent by the server, and the private key information carries out hash calculation on the visitor information in the visitor information list to obtain a hash value, namely the visitor information encrypted by the private key; since there are a plurality of guest information in the guest information list, a plurality of hash values are obtained.
In step 5.4 of the present invention, the visitor information encrypted by the public key information is compared with the hash value in the visitor list, and if the hash value is consistent, it is indicated that the visitor information of the visitor exists in the access control device.
In step 5.5 of the invention, the time of receiving the optical signal is taken as the current access time, and whether the current access time is within the preset access time is judged, if yes, the access requirement is met, and the gate inhibition equipment is opened and released.
