Description

technical field [0001] The present invention relates to a device using power as a communication device, in particular to a device using a magnetic field waveform as a transmission signal. Background technique [0002] Existing home appliance communication systems, such as cable television, computers, local telephones, etc., are divided into "wired connection" and "wireless connection" in order to connect remote signals. [0003] The existing wired connection method mainly uses cables to extend the connection, and then cooperates with signal improvement devices such as boosters to improve the receiving quality. However, using wired optical fiber cables for transmission is expensive and expensive. It is bound to be passed on to consumers, so this is why consumers still have to bear the cost of receiving expensive wired communications.

[0003] The existing wired connection method mainly uses cables to extend the connection, and then cooperates with signal improvement devices such as boosters to improve the quality of receiving signals. However, using wired optical fiber cables for transmission is expensive and expensive. It is bound to be passed on to consumers, so this is why consumers still have to pay for expensive wired communication reception fees

[0004] The existing wireless connection method mainly uses the power line for carrier transmission, but it is limited to a limited area of ​​a power supply meter, that is, within the area of ​​the power supply meter, signals can be made wirelessly Transmission / reception enables information exchange between hardware and hardware. However, because the meter has a built-in transformer, the coupling coil of the transformer will block the carrier signal. Therefore, when the signal reaches the coupling coil, it will be blocked immediately. Therefore, wireless communication The use is limited to a fixed area within the power supply meter, and can no longer be transmitted outside the power supply meter, so the use efficiency of wireless communication is low

[0005] Therefore, the existing wired communication method has the disadvantage of high cost, while the existing wireless communication method is limited by the barrier factor of the transformer supplying the ammeter, and the transmission range is limited. the solution
