The TTL communication standard is single-point communication, and can only communicate with another device at a time, so that the TTL communication standard is suitable for a scene of data transmission between two devices. Therefore, according to different applicable scenes, RS-485 or TTL is selected to be used, and factors such as the distance of communication, the number of devices, the data transmission speed, the signal quality and the like need to be considered.
Further, in a preferred embodiment of the present application, the time control that the elevator reaches the entrance is achieved by setting a timer, the timer can stop at different floor positions according to the difference of the distance between the entrance guard position and the elevator position, and the problem is that the elevator operates according to the distance matched with the timer, so that the elevator can change the time according to the entrance of the visitor better, and the elevator operation is efficient.
Under the condition that time is abundant and has preparation, the visitor can enter through the two-dimensional code, the mode of two-dimensional code can ensure that the visitor can sweep the code to visit at the time quantum that wants to visit, even if resident family is not at home or when resident family is inconvenient to answer by talkback, the visitor also can obtain the chance of entering through the mode of sweeping the code, is applicable to more scenes, satisfies the demand of more resident and visitor.

when the two-dimension code is in a valid state, the entrance guard system exchanges the token in the two-dimension code, wherein the token exchange is actually a token exchange, and the token exchange refers to that in an identity verification mechanism in a network, a user needs to verify the identity of the user through valid information, and an identity verification server generates a token (also called an access token) so that the user can perform subsequent operations on the server. When the user provides a token in the following request, the cloud server uses the token to verify the identity of the user, and determines whether the user has permission to execute the operation required by the request according to the token. And then, after exchanging according to the token, checking, and transmitting the information to a cloud server for checking. The token exchange mechanism can effectively protect sensitive information and resources of users and provide a safer identity verification method. And visitor information for access application is cached in the cloud server, the information obtained by the token exchange is compared with the information cached in the cloud server, and the visiting time and whether the cloud server has the door opening authority are checked.
When the verification result in the cloud server is that the cloud server has the door opening right, the cloud server sends a cloud server door opening instruction to the access control system. And the cloud server returns the door opening instruction and the floor information. The entrance guard system executes a cloud server door opening instruction to open a door, and meanwhile, the entrance guard system is combined with a ladder control through a ladder control adapter to transmit floor information to the ladder control, the ladder control receives information, and an elevator execution operation instruction is selected nearby to form entrance guard and ladder control linkage control.

the cloud end sends a cloud end door opening instruction to the visitor, and corresponding floor information and visitor arrival time are extracted.
5. The access control and elevator control linkage control method based on visitor response of claim 1 is characterized in that the cloud door opening command is sent and simultaneously floor information and accurate time for taking an elevator are returned to an access control system.
6. The entrance guard and ladder control linkage control method based on visitor response is characterized by comprising the following steps:
establishing an audio and video channel through dialing, and initiating audio and video signal connection with a resident terminal; judging the identity information of the visitor by switching on the audio and video;
issuing a remote door opening instruction, and sending floor information and the expected arrival time of the elevator;
and analyzing the remote door opening command, analyzing and obtaining a specific execution command through the protocol adapter, and controlling the door access to open and pass through the execution command through electric signal transmission and controlling the elevator to run and issue in a linkage mode.
7. The entrance guard and ladder control linkage control method based on visitor response according to claim 6, wherein in the step of establishing an audio/video channel through dialing, corresponding calling numbers are set in corresponding floor rooms.
8. The visitor response-based access control and elevator control linkage control method according to claim 6, wherein time control is achieved by setting a timer, so that an elevator can arrive on time.
9. An access control and ladder control linkage control system based on visitor response is characterized in that the access control and ladder control linkage control method based on visitor response is applied to any one of claims 1-8, and comprises a visitor terminal, an access control system, a ladder control system, a cloud server and a resident terminal;
the visitor terminal is used for showing the visitor two-dimensional code to perform identification verification and dialing operation;
the access control system is used for identifying visitor information, uploading visitor two-dimensional code tokens to the cloud, exchanging information, checking door opening permission and establishing an audio/video channel through calling; the access control system is provided with a ladder control protocol adapter for analyzing the standard configuration file;
the ladder control system is used for responding to the execution instruction and linking the entrance guard ladder control;
the cloud server is used for responding to and sending out signals, generating tokens, storing information and checking the door opening authority; the cloud server generates a standard configuration file through a protocol adaptation engine;
the resident terminal is used for sending visitor data acquisition invitation and sharing visitor two-dimensional codes, responding to a call request and sending a remote door opening instruction.
10. The access control and ladder control linkage control system based on visitor response according to claim 9, wherein the standard configuration file performs data analysis tasks according to adaptation rules through a ladder control protocol adapter to realize linkage control; the electric signal transmission is communicated and transmitted through a 485TTL serial port, so that entrance guard ladder control linkage is realized.
