Embodiment Construction

[0037] With the increase of service life, the security equipment is getting old gradually, and it is facing replacement, upgrade and expansion. However, in the past wired deployment method, the equipment was installed by burying the transmission line underground or embedded in the wall, which made it difficult to locate the fault location of the line. It is usually not advisable to slot and break the wall, and it is very difficult to remove and replace. As the society pays more attention to security, the existing security system needs to be expanded to more defense zone access control, but either because the original line pipe cannot be expanded to add new transmission lines, or because the existing control board or interface board wired interface is full. However, it cannot be expanded, which makes it difficult to upgrade and expand the security system, and can only maintain the status quo for a long time.

[0038] In order to reduce the wiring cost of the security system, sh...

Abstract

The invention discloses a multi-protocol switching method for a security system, which comprises a multi-protocol platform training process and a multi-protocol platform working process. As for an unknown target protocol, a training process is firstly carried out on all multi-protocol platforms in the security system, and after the training is finished, the working process is carried out based on a state finally saved in the training process. The multi-protocol conversion device provided by the invention comprises a multi-protocol input / output port, a central processing unit, an RAM, a crystal oscillator circuit, an ROM, a level conversion circuit and a key. When the method and the device of the invention are adopted, inner components of the system do not need to be changed, multi-protocol switching can be realized, and meanwhile, a wireless mode is adopted for communication, and the beauty of the overall security system layout is improved, and the system can be maintained.

Description

technical field [0001] The invention relates to a multi-protocol switching method and a multi-protocol conversion device of a security system, which realize multi-protocol switching in a microsystem. Background technique [0002] Communication protocol (protocol) refers to the rules and agreements that both entities must follow to complete communication or services. Multiple data communication systems in different geographical locations interconnected through communication channels and devices must have a common language, which is a communication protocol, in order to enable them to work together to achieve information exchange and resource sharing. The protocol defines the format used by the data unit, the information and meaning that the information unit should contain, the connection method, and the timing of information sending and receiving, so as to ensure that the data in the network is smoothly transmitted to a certain place. [0003] Security plays an increasingly ...
