Weak current system problem, what is weak current system

Building Intelligence 5a Technology:

OA: Office Automation System.

CA: Communication Automation System.

FA: Fire and Security Monitoring Automation System.

MA: Information Processing Automation System.

BA: Building automation control system.

The content is copied from other people's hehe, typing is too slow:

The building automation system consists of the following components:

Monitoring of the operation and management of construction equipment, including:

1) HVAC system monitoring (HVAC);

2) Water supply and drainage system monitoring;

3) Power supply and distribution and lighting system monitoring.

Fire alarm and fire linkage control, elevator operation control.

Public safety technical precautions, including:

1. TV monitoring system;

2. Anti-theft alarm system;

3. Entrance and exit control and access control system;

4. Security personnel inspection system;

5. Integrated garage management system;

6. All kinds of important warehouse prevention facilities;

7. Security broadcast information system.

Many electromechanical devices are intrinsically interconnected, so perfect automation management is required. Establish a mechanical and electrical equipment management system to achieve comprehensive management, scheduling, monitoring, operation and control of mechanical and electrical equipment.

Functions of the building automation system:

Develop strategies for the management, scheduling, operation and control of the system;

access to data and control parameters;

operation of management, scheduling, monitoring and control systems;

Display the data, images and curves of the system operation;

Printing of various reports;

Analyze the history and trend of the system operation;

Calculate the running time of the equipment, carry out equipment maintenance, maintenance management, etc.

Hospitals, schools, shopping malls, prisons.

The span is relatively large, and each category is purchased one. It's best to ask separately.

Weak current system.

Electric power applications can be divided into two categories: strong current and weak current according to the strength of power transmission. The electricity consumption of buildings and building complexes generally refers to the strong electricity of AC 220V50Hz and above. It mainly provides people with electricity energy and converts electrical energy into other energy sources, such as electricity for air conditioning, lighting, power and so on.

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.

It can be seen that the basic meaning of weak current technology of intelligent buildings is still weak current technology in the original sense. However, with the rapid development of modern weak current high-tech, weak current technology in intelligent buildings is more and more widely used. Such as intelligent fire protection system, monitoring system, computer network, building automation, intelligent broadcasting and so on.

The degree of application of weak current technology determines the degree of intelligence of intelligent buildings.

Weak current system - weak current system engineering.

In general, weak current system engineering refers to the second type of application. Mainly include: 1. TV signal engineering, such as TV monitoring system, cable TV.

2. Communication engineering, such as **. 3. Intelligent fire protection engineering. 4. Sound reinforcement and sound engineering, such as the background of the community, the background of the building.

5. Integrated wiring engineering, mainly used for computer networks. With the rapid development of computer technology, the rapid and powerful software and hardware functions, and the perfect combination of various weak current system engineering and computer technology, the various classifications in the past are no longer as clear as before. The integration of various projects is system integration.

It is not difficult to set up an intelligent company, but it is more troublesome to undertake the qualifications required for the project.

The design and construction qualifications of intelligent weak current are graded, and the registered capital and personnel requirements required for each level are different; Projects with different investment amounts or project nature have certain requirements for the qualifications of bidders.

At present, there are professional qualification requirements for first-level and second-level constructors (mechanical and electrical majors).

Regulatory departments: computer information system integration is under the management of the Industry and Information Technology Commission, intelligent qualifications are under the management of the Construction Commission, security is under the management of the Public Security Bureau, satellites are under the management of the Audio and Video Department, intercom is under the management of the Non-management Bureau, and lightning protection and grounding are ......under the management of the Meteorological Bureau

Funds don't use a lot, hundreds of thousands of you can register one, but this qualification is more difficult to get, you can borrow the qualifications of other companies, pay a certain fee, the lowest is the secondary qualification, that is, the security qualification, and then the construction also has a qualification difference, generally speaking, as long as there is a secondary qualification can do some small projects, as for professional engineers are not needed, at most you need one.

First, the second level of the construction engineer (mechanical and electrical installation), generally speaking, the weak current intelligent to participate in the bidding is the real estate project and the first project, the large is evaluated by the expert group, as for the supervision, the public security bureau is supervised, because it involves security, the weak current is more special, all belong to Party A's direct contracting, there is no classification, now the market is not very standardized, many still need to be improved, because many acceptance of weak current are thrown items, there are also some more important projects that need third-party testing, say more, hehe! There are a lot of things that you need to explore, it doesn't matter if you give the score or not, I have been working in an intelligent company with double A qualification for three years (once).

1. The materials caused by the inattentive on-site investigation are insufficient.

2. Construction non-compliance caused by personnel management errors.

3. The interface is not tightly bandaged, which causes problems in equipment communication.

1. The line is not working, resulting in the equipment not responding.

2. The product quality and product stability are not good.

3. It is recommended to use Jiazhixing's products, such as smart homes, smart hotels, smart communities, etc.
