The invention relates to a wireless intelligent temperature control maintenance system and method for long slope panel concrete. The system comprises a wireless temperature monitoring module, a computer, a wireless receiving module, an electromagnetic relay, a knife switch, an electric heater, a water tank, an electromagnetic flow valve, a water main, a maintenance flower pipe and a temperature probe. The computer receives temperature probe collected temperature data collected by the wireless temperature monitoring module through the wireless receiving module. Through systematic analysis and comparison, if the inner temperature of the concrete is higher than a certain numerical value of the surface temperature of the concrete, the system controls the electromagnetic relay to close and close the electromagnetic flow valve and start the electric heater to heat water for maintenance in the water tank. After the water temperature is raised to meet the demand, the electromagnetic flow valveis turned on and water is sprayed to the surface of the concrete through the water main and the maintenance flower pipe, so that the surface temperature of the concrete is further improved, and the purpose of wireless intelligent temperature control of the panel concrete is achieved.
