What does the weak current system include?

With the continuous development of computer software and hardware technology and the perfect combination with various weak current system engineering, many previous classifications have become unclear. Take the weak current system as an example, many people are not clear about its classification, so what does the weak current system include? What are the problems with the weak current system? Let's take a look! What does the weak current system include?

Weak current, also known as weak current technology, has the characteristics of small current and voltage and is mainly divided into two categories. One is the electric energy that conforms to the national safe voltage, such as alternating current below 36 volts and direct current below 24 volts; Another kind of data source includes voice and image, such as computer network system, video conference system, burglar alarm system, building automation system, etc.

Composition of weak current system

Generally speaking, weak current systems are composed of different systems on different occasions. For example, the weak current system in the hotel consists of an automatic fire rescue system, a monitoring video system and a central air conditioning system. The wireless city weak current system consists of management garage, access control system and the above management system. Therefore, the weak current system will be different for different occasions. The article refers to the weak current system in public places, and its composition can be divided according to functions, including safety prevention system and automatic control system.

1, security system

Indoor part: an indoor safety protection system composed of several subsystems, which can not only ensure the indoor safety of public places, but also transmit indoor related information to the designated dispatching command center. Usually, indoor security system consists of door and window management system, emergency rescue system, fire alarm system and indoor monitoring system. Outdoor part: the outdoor security system is mainly to protect the surrounding safety of public places and monitor all monitoring facilities in the whole public place. It usually consists of security patrol system, infrared alarm system and outdoor monitoring system.

2. Automatic control system

In public places, not only indoor and outdoor security systems are needed, but also multiple automatic control systems are needed to provide automatic control for major equipment systems. Generally speaking, automatic control systems are widely used in public places, mainly lighting systems, fire safety systems, broadcasting systems, power supply systems and drainage systems.

What are the problems with the weak current system?

1, the management and maintenance of weak current system lacks scientific systematicness.

At present, our country adopts traditional management methods for weak current management and maintenance, which divide the weak current system into separate systems for management and maintenance, lacking scientific systematicness.

2. Defects in equipment and materials.

Secondly, the material shortage of weak current system construction mainly depends on two aspects. One is that the weak current construction materials are unqualified, mostly because manufacturers shoddy for profit, which seriously affects the construction quality of weak current system; The other is that all building materials have not been tested before entering the construction site, which leads to the use of unqualified products, thus making the produced weak current system products unable to meet the standards.

3. There are few management and maintenance personnel.

Although China's weak current technology has developed rapidly, it is often impossible to detect the debugging problems of weak current system engineering due to the lack of relevant management and maintenance personnel, which leads to frequent problems after the weak current system is put into use. Thus limiting the normal operation of the weak current system.

4. Lack of acceptance

As we all know, every project needs to be completed and accepted, and so does the building weak current system project. Therefore, when organizing and debugging the weak current system engineering of buildings, it is often encountered that the inspection is not in place, which makes some problems still exist after the construction project is put into use. Insufficient acceptance of weak current system engineering in intelligent building will limit the function of the building.

Solution measures

1, strictly control the quality of materials.

The equipment and materials needed for the whole system construction must be strictly controlled. First of all, there must be the production certificate of the materials used, including the confirmation of the product name, production specifications, production date and other information of the whole material equipment. Secondly, carefully check the verification and inspection records of equipment and materials, including on-site inspection of packaging, appearance and functionality in accordance with state regulations. If the on-site inspection conditions are not available, the manufacturer may be required to issue inspection results after inspection of equipment and materials, or the results after inspection may be required in accordance with state regulations. Finally, check whether the specifications of materials and equipment meet the requirements of construction specifications, check whether the imported goods have inspection and verification records, and also have document descriptions of the assembly, installation, operation and maintenance of equipment and materials to ensure the construction quality of the project.

2. Do a good job in the unified deployment of subsystem construction time and documents.

The whole system is composed of different subsystems, and the construction time of subsystems is different, so it needs to be deployed and coordinated in the whole construction process. Mainly according to the requirements of construction, design the specific construction site plan, including the construction time and location of each subsystem and the construction scheme of the overlapping part of each subsystem. In the later planning revision, we should improve our practice on the basis of not violating the overall planning. The construction of system engineering is huge and complex, and an integrated system is needed to record the responsible personnel, handover time and handover personnel of each subsystem in a unified way, so as to achieve orderly management, facilitate inquiry and facilitate decentralization of responsibilities.

3. Construction quality verification

The construction scope of weak current system is very wide, including many fields, and it needs to be finally verified by professional units or individuals to test whether it has safe and effective use effect. The first is the verification after the completion of each subsystem construction. Finally, there must be the final signature of the preparation engineer. Without signature, the next project construction can never continue. Secondly, we must carefully check the overlapping parts of the project to avoid omission, duplication and confusion. Finally, when the project is completed, the design of the whole weak current system must be strictly tested and verified according to the national regulations or the specific requirements of related majors.
