IC Substrate - What is carrier control board?

Carrier control board refers to the control of a device through a carrier wave. Power Line Communication, also known as PLC, is the abbreviation for Power Line Communication in English. Power carrier communication is a unique communication method in the power system, which refers to the technology of using existing power lines to transmit analog or digital signals at high speed through carrier communication. The biggest feature is that there is no need to rebuild the network, as long as there are wires, data transmission and control can be carried out.

The advantages of the carrier control board

There are many advantages to applying power carrier wave in intelligent network home appliance control:

(1) Can utilize existing power lines to form a network

(2) Because there is no need to re-lay the net, it can save financial, material, and human resources

(3) Stable and reliable, easy to implement

(4) At present, there are multiple types of power carrier chips on the market that can be selectively selected

Architecture of Power Carrier Communication Network

Power line carrier communication is a communication method that uses power lines for information transmission, so using power lines can form a communication network for home environments. The power carrier communication network generally adopts a master-slave control mode. In the figure, there is one master CPU in the upper layer and several slave CPUs in the lower layer. The main control CPU issues instructions to each slave CPU to coordinate work, and only one CPU can use power line resources at the same time. The main control CPU is connected to the gateway or home server, and the intelligent circuit is controlled by the CPU.

Application fields of the carrier control board

1. The smart home control network can be implemented using power line carrier technology. The principle is to integrate power line carrier technology and embed it into various electrical appliances, and use the existing power line in the home as the carrier communication medium to achieve communication and control between smart devices. The interconnection and interaction of smart appliances in the smart home control network will bring you a high-quality life experience and enjoyment:

1) Always check the status of all electrical appliances

2) Centralized control of all smart electrical devices in the home with any switch

3) Group on/off designated electrical appliances, such as scene lights, etc

4) Always keep track of household security situations, such as theft prevention, fire alarm, gas leak detection, etc

5) Remote control of household appliances through the internet or telephone

2. The Remote Automatic Meter Reading (AMR) system is one of the important applications of intelligent control networks. It can enable power suppliers to improve service quality while reducing management costs; And provide users with the opportunity to fully utilize various electricity consumption plans (such as time of use electricity prices) to save costs and enjoy various conveniences. System functional characteristics

1) Remote automatic meter reading

2) Remote control of electricity meter opening and closing

3) Real-time query of user electricity consumption

4) Meter usage group reading or individual selection reading

5) Can be integrated with the billing system

3. The remote street lamp monitoring system utilizes power carrier technology to connect the street lamp lighting system to an intelligent lighting system through existing power lines. This system can save electricity while ensuring road safety, extend the lifespan of lighting fixtures, and reduce operating and maintenance costs. System functional characteristics

1) 24/7 automatic monitoring

2) The monitoring range can reach several kilometers

3) After adding the automatic routing function, the monitoring range doubles

4) Single lamp status detection: voltage, current, switch, temperature, etc

5) Automatic reporting of single lamp fault status for energy-saving control of the lighting system

A carrier control board through a power carrier remote control system is beneficial for improving the safety and reliability of the power system.
