The transmission rate of this circuit can reach at least 32kbit/s. If the carrier is higher, the speed can be faster. For the sake of simplicity, the key switch we use does not have a noise reduction function, and can be implemented in software if desired. U1 is a PIC microcontroller with several peripherals and a PWM module. It should be noted that this circuit can only be used in low voltage and low voltage environments, and cannot be connected to high voltage. For industrial control environment wired communication equipment and wireless communication equipment. Wired communication equipment mainly introduces serial equipment communication for industrial field, professional bus-type communication, industrial Ethernet communication and conversion equipment between various communication protocols, including routers, switches, modems and other equipment.

How to communicate data on weak wires
If network communication is to be carried out using existing indoor wiring lines, the power line carrier is generally used to transmit data on the strong electric line. Now come up with a simpler, cheaper and more reliable way, as long as several discrete devices and two ICs communicate via weak current circuits (such as telephone lines).
