According to the problem that the power monitoring system is physically isolated from the Internet and the monitoring information is not easy to be transmitted outward

it proposes two-dimensional code recognition to realize unidirectional isolated transmission of power monitoring information.Using QR code as the key transmission carrier

it forms the alarm window information into a transmission queue

encoded

recognized and decoded one by one

and achieves information transmission in a secure and physically isolated environment.The experiment shows that the transmission system has high transmission stability and can meet the application requirements of transmitting power monitoring information externally.
