Host computer with intelligent bus interface and security system

Abstract

The invention discloses a host computer with an intelligent bus interface, and aims at providing a host computer capable of making different devices of different types, different protocols, different addresses and different baud rates simultaneously share one bus interface to be communicated with the host computer, and the host computer comprises a bus interface which is connected with devices through a bus, and the host computer with the intelligent bus interface also comprises a bus management module which is connected with the bus interface and a device management module which is connected with the bus interface and the bus management module, wherein the occupation of the bus is gradually allocated to each device according to time slices, a parameter of the bus is adjusted to the parameter which is consistent with the device when each device acquires the bus occupation, and a communication starting instruction is transmitted; and the device management module receives the communication starting instruction and notifies the host computer to utilize a protocol corresponding to the device acquiring the occupation to be communicated with the device according to the communication starting instruction. The invention also discloses a security system. The host computer with the intelligent bus interface can be used for the security system.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a bus interface of a security system. Background technique [0002] With the development of digital technology and the increasingly widespread application of communication technology, a current security system is often composed of multiple types of devices, and the host and devices are connected to each other through various buses and bus interfaces. See image 3 , the figure reveals the principle of the existing security system. The host is provided with bus interface A and bus interface B. Bus interface A connects several class A devices through bus A, such as class A device 1 to class A device N, and bus interface B Several class B devices, such as class B device 1 to class B device M, are connected through the bus B. [0003] In the existing technology, the same bus and bus interface of the host can generally only be connected to the same type of equipment, and the bus con...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the problem that the same bus and bus interface of the host in the prior art can only be connected to the same type of equipment, the bus connected between the equipment and the host can only use the same protocol and baud rate communication, different types and different protocols 1. Devices with different baud rates cannot share the same bus and bus interface to communicate with the host at the same time. There are technical problems such as high bus resource occupancy, difficult construction, and high cost. A host and security system with an intelligent bus interface is provided.
