The intelligentization of weak currents in construction projects can effectively improve the operation quality of weak electrical equipment. Thanks to the development of intelligent technologies, various weak electrical infrastructures in the district have been gradually established, and a sound and complete intelligent service has been formed, in order to ensure the intelligentization of weak electrical power. It is necessary to strengthen the management of intelligent construction of weak currents, operation and maintenance of the later period, and then to improve the level of intelligentization of weak electricity as a whole.
The connotation of a weak electricity intelligence
Weak compared to strong electricity mainly refers to the safe voltage within the scope of control and control of the State Grid, and low voltage electrical energy, the specific standard is usually: DC is less than 24V, AC is less than 36V. With the development of modern intelligent technologies, weak currents are gradually becoming more intelligent and advanced, including: communications automation, building automation, fire automation, and security automation. The actual application to the construction engineering system includes: fire fighting systems, communication systems, etc. Intelligentization of weak currents is the result of continuous development of modern automation and intelligent technologies. It can gradually promote the intelligent construction of electrical systems for construction projects and improve the intelligent level of construction projects.
Design and application of intelligent design for weak engineering in II
1. Survey on the needs of intelligent weak currents. The intelligent construction of weak currents cannot be achieved in one step. It requires a concrete and systematic process. It needs to be gradually implemented according to the characteristics, functions, objective needs, and capital input of the buildings. Before the actual construction of smart electricity, it is necessary to do a good job of investigating and analyzing the internal demand of the entire power system. In this case, it is necessary to inquire the electricity customers, and the need for the use of weak electricity in the future. Scientific planning and active construction will create an economical, advanced, and scientific weak and intelligent system, and play an advanced role in smart technology.
2, intelligent design. According to the previous investigation of the demand for intelligent weak currents and the development of intelligent equipment and technology in the market environment, it is necessary to have qualified technical personnel responsible for intelligent design. The key to the intelligent design of weak current systems is from several Key points to start: Suitability of the system structure, the scientific distribution of lines, the rational distribution of equipment, etc., each link must be matched with professional, specialized designers to focus on analysis, design, to strengthen coordination and collaboration between all links Communication, at the same time, we must also carry out weak-current intelligent design according to structural characteristics of construction projects, customer service requirements, etc., and must clearly define the conditions required for each link design and system operation, and coordinate and communicate with common designers. The conditions for system operation correspond to the rational design of weak-current intelligent drawings.
3, the application of weak intelligence. (1) The television signal distribution system's intelligentization of television signal distribution system is mainly reflected in the use of micro-television reception systems, improving the quality of television signal reception, and not subject to the constraints and influence of regional terrain conditions, landform conditions, etc. The signal strength is strong.
(2) In the intelligent building engineering of the security system, monitoring and management of the security system are indispensable. The so-called monitoring system is generally based on the installation of cameras and related monitoring facilities to monitor the security of a building community and a residential area as a whole. Scientific characteristics. The system can deliver clear pictures, and it can perform all-weather automated monitoring of the community and dynamically grasp all information within the community, thus providing evidence for the emergence of security issues.
(3) The development of the intelligent technology of fire intelligent systems promotes the automation and intelligence of fire alarm systems in construction projects. The automatic fire monitoring equipment is assigned to the fire control headquarters according to the specific regulations, and the interior of the community is fully automated and monitored. Supervision, specific intelligent equipment is: Smoke detectors are generally allocated in the public space corridors, leisure platforms and other locations. The underground garage is usually equipped with a temperature detector to make use of the automatic sensing and monitoring functions of the detector. At the same time, the automatic alarm equipment is installed inside the building space, and the gas detection equipment is also installed inside the residential building. These intelligent sensor devices usually have sensitive sensing effects and can automatically sense changes in the outside temperature, smoke, etc., thereby promptly issuing alarm signals to realize the automation and intelligence of fire fighting.
(4) The license plate recognition system is equipped with an automatic identification device at the entrance of the cell, enters the license plate number, access time, etc. of the vehicle inside the cell, and establishes the relationship between the automatic identification device and the barrier machine so as to achieve the interior of the cell. Automated identification of vehicle license plates enables automatic alerting and the closing of community gates when an external vehicle enters. This saves time for card swipes and eliminates the need for card recharging.
Three intelligent building weak current system design
In the intelligent building weak current system, integrated wiring is a very important part. Intelligent building computer network system and modern communication are all realized through integrated wiring. In the intelligent building weak electronic system public broadcasting paging system, security system, multimedia In systems such as conference systems, integrated cabling also plays an important role.
(1) Public broadcasting paging system. The public broadcasting system is mainly responsible for delivering some news information, entertainment information, and emergency information for people. The public broadcasting paging system is an indispensable part of intelligent architecture. When designing a public broadcasting paging system, it must ensure that it has two basic functions of emergency broadcasting and playing music for people. Among the many functions of the public broadcasting paging system, the emergency broadcasting function is the most important one when it comes to emergency situations. At that time, the emergency broadcast master controller can promptly trigger and activate the emergency broadcast function of each sub-district to let people know their own environmental conditions. If a disaster occurs, they can guide people to self-rescue, thereby reducing the number of casualties. In daily work, each section of the public address paging system can operate independently. If there is no broadcast information, some music can be played for people to make people feel happy.
(2) Security system. In an intelligent building, the security system is an important part of the weak current system. The security system consists mainly of anti-theft alarm systems, monitoring systems, access control systems, and electronic patrol systems. The most important of these systems is monitoring. The main function of the system and the monitoring system is to monitor the surrounding environment of the building, main internal passages, building elevators, offices, etc. If a theft or the like occurs in the building, the monitoring system can provide video effects to the department, which effectively Reduce the incidence of theft. Because different buildings have different features, therefore, in the design of building safety precautions system, we should choose a reasonable camera according to the actual situation, so as to give full play to the function of the camera. At the same time, in order to ensure the practicality and accuracy of system recording, a digital hard disk recorder can be selected. This recorder can record 24 hours without interruption, and also has the functions of displaying and playing back. Anti-theft alarm system has a very important role in the internal security of buildings. It can provide timely and effective safety information for people. In the weak design of intelligent buildings, the design of the anti-theft alarm system can be implemented by the wall infrared radiation, so that theft occurs. After the alarm can be issued in a timely manner.
(3) conference system design. With the rapid development of society and economy, people’s communication methods have also undergone tremendous changes. At the same time, many conference facilities are also moving towards the direction of networking, high efficiency, convenience, and multimedia. In intelligent building weak current systems, conferences The system is becoming more and more important. There are many conference systems, multimedia video systems are installed, and the pronunciation system is recalled hand in hand. This greatly satisfies people's needs. In the design of the conference system, the designer must reasonably design the sound reinforcement system according to the conference environment. Only in this way can the normal operation of the conference system be guaranteed. Under normal circumstances, when designing a sound reinforcement system, it is necessary to conduct sound reinforcement and sound reinforcement. At the same time, the designer must carefully analyze sound absorption, diffusion, and reflection to ensure soundness of the sound reinforcement system. In recent years, more and more conference systems have added multimedia video systems. Multimedia video systems are mainly composed of electronic whiteboards, physical display stations, and video conversion devices. Designers must design audiovisual videos when designing multimedia video systems. The positions of the outlets, conference tables, etc. are comprehensively considered to ensure the smooth implementation of the two-way exchange of the network video conference.
(4) Precautions for the design of weak systems for intelligent buildings. The design of intelligent building weak current system is a systematic task. At present, China still has many problems in the design of weak systems for intelligent buildings. On the one hand, it lacks scientific configuration when designing weak building systems for intelligent buildings, and on the other hand, it is the selected technology. It is impossible to meet relevant standards. To effectively improve the design quality of weak building systems for intelligent buildings, designers must pay attention to the principles of advanced technology, economical efficiency, seeking truth from facts, and stability in the design of weak electrical systems. Only in this way can the use of weak building systems for intelligent buildings be extended. Lifespan can give full play to the function of intelligent building weak current system.
Four conclusions
The weak current system design of intelligent buildings is a complex project involving a wide range of areas and relatively high technical requirements. Therefore, the designers proceed from the actual situation, carefully analyze the influencing factors, do a good job in design preparation, and design scientifically and rationally. Smart building weak current system.
