Water heater remote control system

The invention provides a water heater remote control system. The water heater remote control system comprises a receiving end carrier module, a receiving end signal resolution chip, a voltage control circuit, a power line carrier module, a central control chip, a transformer, a communication module and a network background. The power line carrier module and the transformer are connected with the power input of a household power supply. The transformer is connected with the central control chip, reduces the voltage of the household power supply to 5V and transmits the voltage to the central control chip. The central control chip is connected with and controls the power line carrier module. The water heater remote control system is low in mounting cost; a user just needs to conduct proper transformation or additional mounting on an existing electric power line and an existing household appliance without completely replacing a water heater, and therefore the problem of high replacement cost does not exist; internal control signals are transmitted in a power line carrier mode, and the problem of communication conflicts is effectively avoided; a user achieves control through short messages; as long as the user is not an illiterate and can use the basic functions of a mobile phone, the user can complete control well; accordingly, the situation that it is hard for most of middle-aged and aged people to learn to use applications (APP) is effectively avoided.
