Claim 9:
10. The electric heating thermal management system for the oil and gas transportation pipeline based on renewable energy and CO2 energy storage according to claim 1, wherein the early warning device has an intelligent mode and an artificial mode; the intelligent mode: when data values fed back by a temperature sensor and a pressure sensor reach a preset temperature threshold and a preset pressure threshold, an intelligent command control device energizes the electric tracing bands so that oil and gas temperature in the oil and gas transportation pipeline is always kept above the critical temperature for formation of the solid matters; the artificial mode: the early warning device transmits a signal to the remote operation device; and a field operator instructs the control device to set different parameters to energize the electric tracing bands at different positions, controls the heating temperature, and combines with an inhibitor to jointly act when necessary to ensure the safe and effective operation of the transportation pipeline on the premise of low cost.
