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

The problem of signal attenuation that carrier control boards experience over long distances can be solved in a number of ways:

Signal attenuator is a good way to solve the signal attenuation of carrier control board. The power line broadband carrier signal attenuator can separate the current from the signal and process the signal with appropriate attenuation, which can ensure the normal power supply of the power line and control the signal in transmission. In this way, all the electrical appliances in the house can work stably and the signal transmission is more reliable.

Advanced signal coupling technology can also greatly reduce signal attenuation. By communicating in different frequency bands of the power system, frequency selective coupling technology can avoid interference with the power system. This technology can flexibly adjust the signal transmission path according to the actual demand and improve the reliability of transmission.

Optimizing the design of the carrier control board and related equipment is also the key to solving signal attenuation. For example, by improving the circuit design and adopting phase-locked loop frequency synthesis technology, the stability of the signal can be significantly improved. In addition, optimizing the impedance matching of the transmission line and reducing unnecessary signal reflection can also effectively reduce signal attenuation and improve transmission quality.

For long-distance transmission, the use of relay devices is a good choice. The relay device can enhance the signal strength between different nodes and extend the transmission distance of the signal. The signal is re-amplified and processed by additional devices on the power line to ensure that subsequent nodes can receive the data accurately. This method is particularly suitable for scenarios that require high signal quality and can significantly improve system performance.

Choosing the right type of power line is also important when designing a carrier control system. The use of single- or dual-core DC power lines can improve signal transmission performance and reduce attenuation problems caused by line characteristics. Properly configuring the line ensures smooth current and signal transmission and optimizes overall performance, resulting in more reliable long-distance transmission.

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