and when the network signal is not greater than the transmission signal threshold, the data encryption module transmits the encrypted water quality data to the data temporary storage module, and when the network signal is greater than the transmission signal threshold, the data temporary storage module retransmits the encrypted water quality data to the remote processing center.
