Access control device, user terminal, background system and method for the access control device

Abstract

The invention discloses a door access control device using background system services, a user terminal having visual intercom function, and a background system and control method serving for the door access control device and the user terminal, and is intended to solve the problem that visual intercom implementation between a door access control device and a user terminal has problems with functionality, timeliness, scale and development cost. The background system controls a user terminal to visually intercom with the door access control device through a master control module, a message processing module and a signal processing module, and controls unlocking of the door access control device, and visual intercom may also be provided between user terminals through the background system. The main design idea of the invention lies in the background system, call login is allowed only when an accessed door access control device to make calling and a user terminal need to make correspondence, and call connections are decreased. Therefore, more concurrent call connections can be handled at the same time, equipment and network investment operation costs are greatly decreased, and the amount of users can be quickly increased on a large scale.

Description

technical field [0001] The invention relates to a building / community / residential access control device system, in particular to an access control device system with a visual intercom function. Background technique [0002] The current residential / building / residential video intercom access control systems basically use wired connections to provide each household with wired access to the network or analog video and audio signals, and then provide each household with a dedicated video intercom device / control device. The disadvantage of this kind of system is that the equipment and lines must be designed and installed during the planning and construction of the building, and the equipment and lines after use in the later period are aging and damaged. The home access equipment seems to be outdated and not easy to use because it cannot keep up with the progress of the times. However, if these devices and related lines are replaced, community residents and property companies are ...

Problems solved by technology

Another example is the solution of 201510414957.5, which involves intercom-capable access control and mobile terminals, as well as the background system, but it does not implement the visual intercom function, and the background system also has many restrictions

Another example is 201410744548.7, which only enables the user to use the mobile terminal to call the access control device for visual intercom function, but cannot call the user's mobile terminal through the access control device

[0004] In short, the above-mentioned solutions have a series of problems such as incomplete functions, complicated implementation, high cost, inconvenient use, and high daily expenses. Of course, the most important thing is that they have not considered how to solve them when the scale of users and access control equipment is large. Background system performance, load capacity, equipment investment and operating costs
