A system for providing powerline communication over flexible mesh for circuit design used in biometric monitoring is disclosed. In particular, the system provides for the transmission of power and data over the same circuit infrastructure, and integrates the ability to transfer data over an infrastructure that also transmits power. Notably, the system facilitates the integration of data over power in flexible systems, such as systems incorporating flexible mesh sensors and flexible geometric systems. The dual use of power infrastructure reduces weight and increases flexibility and potential sensor density. The systems use of data over power significantly reduces or eliminates the needs for a standalone data bus, thereby reducing the design complexity of the circuit.

A photovoltaic system and a communication method therefor. The communication method includes: each slave sends a report signal to a host, and monitors a response signal of the host; and if the at least one slave receives the response signal, the corresponding slave executes a corresponding action on the basis of the response signal. Therefore, communication between the host and each slave is achieved in a mode that each slave actively sends the report signal, the host is prevented from adopting a roll call query mode, and occupation of bus resources by the host is reduced.
