Introduction to weak current integrated system, how to achieve weak current system integration?

Hello, the integration of weak current system is mainly done through software, and the structure can be seen in the figure below

The architecture of the integration platform can be divided into:

1. Underlying equipment and support network - device layer and interface layer.

This layer is composed of the drivers of control, subsystem or equipment included in the IBMS system and the related integrated wiring, communication and computer network systems, and this layer mainly completes the real-time information collection and processing of the field control equipment of the subsystem. Since each subsystem may use different communication protocols and data formats, the driver system at this layer should complete the conversion of different protocols and data formats. That is, the different communication protocols and data information formats of each subsystem are converted into the mega protocols and formats recognized by the upper layer (core decision-making layer), and the information processed by the core layer is converted into the protocols and formats recognized by the corresponding subsystems.

Complete the control and management of each subsystem. This layer actually acts as a communication gateway, which can also be called a communication gateway.

2. Core decision-making - management and service level.

This layer is a key part of the whole system, is the "nerve center" of the whole system, and the main work it completes is:

1) Complete the processing of the information of each subsystem input by the bottom layer according to the internal logical system, send the processed results to the corresponding database, and notify the upper layer to display it in an intuitive way. At the same time, it accepts the request information sent by the upper layer (GUI) authorized operator or the control information of the system to process these information accordingly, and notifies the driver layer of the result, and the driver layer notifies the corresponding subsystem to complete the corresponding action.

2) Accept the request information of the information comprehensive management issued by the upper layer (GUI) authorized operator, complete the comprehensive processing of the requested information as required, and return the result to the GUI layer for its display and output.

3) Complete the linkage function processing of each subsystem, and the occurrence of an event will not only cause the reaction of the subsystem to which the event belongs, but also cause other subsystems associated with it to take corresponding actions. This linkage is decided by the core layer.

4) Provide standard API interface for the lower and upper layers, and standard ODBC interface for the database system to complete the internal communication with all parts of the system.

3. Human-computer interaction - application layer.

This layer is a window for human-machine dialogue, on the one hand, the information processed by the core layer is displayed on the computer screen in a clear and intuitive way, providing users with real-time monitoring and control of all on-site information of the entire building. On the other hand, through this layer interface, users can complete the function configuration and setting of the subsystem according to the pre-design, complete the linkage setting and comprehensive management of the system. The user interface layer can support web technology, browse all information in the Internet intranet environment through a browser, and complete the remote control and management of the system through authorization.

Weak current system, system integration, intelligent building three connection and difference explanation.

To put it simply, it should be that many subsystems in weak current projects can be done.

Weak current system integration is a general term, and weak current system integration includes security system integration;

Security system integration is a branch part of weak current system integration.

The integration of weak current system is the integration of various subsystems, and security is the integration of civil air defense (security personnel), physical defense (doors, fences, fences), and technical defense (technical prevention).

The security system is a part of the subsystem in the weak current system.

The so-called system integration (SI, system integration) is to integrate the separated devices (such as personal computers), functions and information into an interrelated, unified and coordinated system through a structured integrated wiring system and computer network technology, so that resources can be fully shared and centralized, efficient and convenient management can be realized. System integration should adopt a variety of integration technologies such as function integration, network integration, and software interface integration. The key to system integration is to address the interconnectivity and interoperability between systems, and it is a multi-vendor, multi-protocol, and application-oriented architecture.

This needs to solve all the integration-oriented problems related to subsystems, such as interfaces, protocols, system platforms, and application software between various devices and subsystems, such as subsystems, building environment, construction coordination, organization management, and staffing.

There are two main types of weak current in intelligent buildings, one is the safety voltage level and control voltage and other low-voltage electric energy stipulated by the state, which are divided into AC and DC, AC 36V or less, DC 24V or less, such as 24V DC control power supply, or emergency lighting backup power supply. The other type is information sources containing voice, images, data and other information, such as **, television, computer information. People are accustomed to calling the technology of weak current as weak current technology.

Weak current system, system integration, intelligent building three connection and difference explanation.

To put it simply, weak current integrated equipment is a general term for systems below 220 volts, including network, **, cable TV, home defense, monitoring, access control, intercom, garage barrier, perimeter, patrol, elevator control, fire protection, BA system, etc., and now it has also added the Internet of Things system, such as smart home networking equipment, etc., I hope to help you, I wish you happiness.
