What does light current engineering do?
Light current engineering work content: communication, network, parking lot, monitoring, alarm access control, patrol inspection, access control attendance, public broadcasting, etc.
System integration is a highly technical system engineering. To truly integrate a building light current system, not only the current engineering company is required to compare the functions, technical parameters, construction, installation, and debugging of each light current system product. In-depth mastery, but also a more comprehensive understanding of the building's water supply and drainage system, power supply and distribution system, ventilation and air conditioning system, lighting system, elevator system and so on.
At the same time, because the building light current system involves many modern high-tech technologies with high technical content, such as communication, computer system, control and display, etc., the update and development are very fast. Therefore, in the specific implementation process of system integration, there are many technical details. The solution also requires the support and cooperation of various professional and technical personnel.
Light current engineering smart building electrical technology still includes two categories: strong current and weak current. The electricity consumption of buildings and buildings generally refers to strong electricity of 220v50hz and above. It mainly provides electric energy to people, such as electric drive motor, lighting and so on.
There are two main types of weak electricity in smart buildings. One is low-voltage electricity such as the state-regulated safety voltage level, which is under the jurisdiction of the National Communication Security Committee and the control voltage. There are AC and DC points, such as 24v DC control power supply, or emergency lighting backup power supply. The other type is information sources that contain information such as voice, video, and data, such as information from monitors, TVs, computers, and intercoms.
People are accustomed to referring to the weak current technology as weak current technology. It can be seen that the basic meaning of weak current technology in smart buildings is still the weak current technology in the original sense. However, with the rapid development of modern weak current technology, the application of weak current technology in smart buildings is becoming more and more extensive.
The degree of application of weak current technology determines the degree of intelligence of smart buildings.
Commonly used building weak current engineering systems mainly include the following:

Electric power applications can be divided into two categories according to the strength of power transmission power: strong electricity and weak electricity. The electricity consumption of buildings and building complexes generally refers to strong electricity with AC 220V50Hz and above. It mainly provides electric energy to people and converts electric energy into other energy sources, such as air conditioning electricity, lighting electricity, power electricity and so on.
There are two main types of weak electricity in intelligent buildings. One is low-voltage electrical energy such as the safety voltage level and control voltage stipulated by the state. It is divided into AC and DC. Lamp backup power. The other type is information sources that carry information such as voice, image, data, etc., such as telephone, television, computer information.
Identification of strong electricity
1. Strong electricity is not equal to power consumption. A lot of strong electricity is used for power, such as motors, air conditioners and elevators, but it is also used to power computers, TVs and other equipment. For another example, the power of an electric vehicle is a 12V battery, which cannot be called strong electricity.
2. It cannot be demarcated by frequency or AC and DC. For example, 800KV DC transmission must belong to strong electricity.
3. It cannot be demarcated by the magnitude of the current. The working current of many high-voltage devices can be very small, but the communication power supply is low-voltage and high-current.
The difference between strong electricity and weak point
Strong electricity and weak electricity are relative concepts. Conceptually, the main difference is the difference in use, and the relationship between the two cannot be simply defined by the size of the voltage (if you have to specify the voltage to distinguish, then the 36V (human body safety voltage) ) above is classified as strong electricity, and below 36V (human body safety voltage) is classified as weak electricity.), both are related and different. The general principle of distinction is: the processing object of strong electricity is energy (electricity), which is characterized by voltage High, large current, high power and low frequency, the main consideration is to reduce loss and improve efficiency. The processing object of weak current is mainly information, that is, the transmission and control of information, which is characterized by low voltage, small current, low power and frequency. The main consideration is the effect of information transmission, such as the fidelity, speed, breadth and reliability of information transmission. They roughly differ as follows:
(1) The AC frequency is different
The frequency of strong electricity is generally 50Hz (Hz), which is called "power frequency", which means the frequency of industrial electricity: the frequency of weak electricity is often high frequency or ultra-high frequency, measured in KHz (kilohertz) and MHz (megahertz).
(2) Different transmission methods
The strong electricity is transmitted by transmission lines, and the weak electricity transmission is divided into wired and wireless. Radio transmits by electromagnetic waves.
(3) The power, voltage and current are different
Strong electric power is measured in KW (kilowatt), MW (megawatt), voltage is in V (volt), KV (kilovolt), current is in A (ampere), kA (kiloampere); weak current power is in W (watt) , mW (milliwatt) meter, voltage in V (volt), mV (millivolt), current in mA (milliampere), uA (microampere), so its circuit can be composed of printed circuits or integrated circuits.
There are also high-frequency (hundreds of KHz) and intermediate-frequency equipment in strong electricity, but the voltage is higher and the current is also larger. Due to the development of modern technology, weak electricity has penetrated into the field of strong electricity, such as power electronic devices, wireless remote control, etc., but these can only be regarded as the weak electricity control part of strong electricity, which is different from the controlled strong electricity.
According to the fundamental principle of weak electricity conduction signal and strong electricity conduction electric energy, we can easily distinguish strong electricity from weak electricity. For example, although electric shavers, flashlights, etc. only use two dry batteries (3V), we cannot consider them to be weak currents because the voltage and current of the electrical appliances are small, because they conduct electricity instead of signals, so they should belong to the strong current category. .
From the above description, the relationship between the four can be roughly explained as follows:
High voltage must include strong electricity, and strong electricity does not necessarily belong to high voltage;
Low voltage must include weak current, and weak current must belong to low voltage;
Low voltage is not necessarily strong electricity, and strong electricity is not necessarily low voltage.
