The weak electricity relative to the strong electricity mainly refers to the safety voltage within the control and control range of the national grid, and the low voltage electric energy. The specific standards are usually : the direct current is lower than 24V , and the alternating current is less than 36V . With the development of modern intelligent technology, the weak electricity is gradually becoming intelligent and advanced, including : communication automation, building automation, fire automation and security automation. Practical applications in construction engineering systems include : fire protection systems, communication systems, etc. The weak electricity intelligence is the result of the continuous development of modern automation and intelligent technology. It can gradually promote the intelligent construction of building engineering electrical systems and improve the intelligent level of construction engineering operations.
1. Survey of weak electricity intelligence needs. The construction of weak electricity intelligence cannot be completed in one step, and a specific and systematic process is needed. It needs to be gradually implemented according to the characteristics, functions, objective needs, and capital investment of the building. Before the actual construction of weak electricity intelligence, it is necessary to conduct a survey and analyze the internal demand of the entire power system. In this case, it is necessary to inquire about the use of electricity customers and the need for weak electricity use in the future. Scientific planning and active construction will create an economical, advanced and scientific weak electric intelligent system, and play the advanced role of intelligent technology.
2 , intelligent design. According to the investigation of the early-stage weak electrical intelligence requirements and the development of intelligent equipment and technology in the market environment, it is necessary to have qualified technicians to be responsible for intelligent design. The most important key to the intelligent design of weak current systems is to Key points : suitable system structure, scientific route distribution, rational distribution of equipment, etc. Each link needs to be equipped with professional and specialized designers to focus on analysis and design, and coordination and cooperation between each link should be strengthened. Communication, at the same time, according to the structural characteristics of the construction project, customer service needs, etc., to carry out the intelligent design of weak electricity, to clearly define the conditions required for each link design, system operation, etc., to coordinate and communicate with the common designers. The conditions for the operation of the system correspond to the rational design of weak electrical intelligent drawings.
3. Application of weak electricity intelligence.
(1) The intelligentization of the TV signal distribution system of the TV signal distribution system is mainly embodied in the application of the micro-television receiving system to improve the reception quality of the television signal, and is not subject to the constraints and influences of the terrain and geomorphic conditions, and the signal strength is strong.
(2) The monitoring and management of the security system is indispensable in the intelligent construction of the security system. The so-called monitoring system generally monitors the safety of a building community and a community by installing cameras and related monitoring facilities. , scientific and other characteristics. The system can transmit clear pictures, and can automatically monitor the community around the clock, dynamically grasp all the information inside the community, and provide evidence for the emergence of security problems.
(3) The development of intelligent technology of fire-fighting intelligent system promotes the automation and intelligence of the fire-fighting alarm system in construction engineering. According to the specific specifications, the automatic fire monitoring equipment is equipped in the fire control command department to fully auto-monitor the interior of the community. Supervision, the specific intelligent equipment is : smoke detectors, generally located in the building public space corridor, slow platform and other locations. The underground garage is usually equipped with a temperature detector to take advantage of the detector's automated sensing and monitoring functions. At the same time, the automatic alarm device is installed inside the building space, and the gas detection device is also installed inside the residential building. These intelligent sensing devices usually have more sensitive sensing effects, and can automatically sense changes in external temperature, smoke, etc., so as to issue alarm signals in time to realize automation and intelligence of fire protection.
(4) The license plate recognition system is equipped with an automatic identification instrument at the door of the community, inputting the license plate number, entry and exit time of the vehicle inside the community, and establishing the relationship between the automatic identification instrument and the railing machine, so as to achieve the internal The automatic identification of the vehicle license plate can automatically issue an alarm and close the cell door when an external vehicle enters, thus saving the card time and eliminating the trouble of card recharge.
