The invention provides a circuit capable of changing a load operation function in a temporary outage mode. The circuit comprises an outage detection circuit, wherein the input end of the outage detection circuit is connected with a power source, and the electric power of the outage detection circuit is supplied by the power source. The output end of the outage detection circuit is connected with a micro controller unit (MCU), and then the MCU is connected with at least one load driving circuit. A load electric appliance is mounted on the load driving circuit. A switch is arranged between the outage detection circuit and the power source in a parallel connection mode. A program controlling the load electric appliance is set in the MCU. When the circuit is used, the switch can be turned on / off temporarily so that the power source can restore power supply immediately after a temporary outage; the outage detection circuit detects a signal of the temporary outage of the power source and transmits the signal to the MCU; the MCU controls the load electric appliance to achieve another operation function by means of controlling the program of the load appliance according to the signal.
Description
technical field [0001] The invention relates to a circuit for changing load operation function by means of temporary power-off, in particular to a circuit for controlling the function of load by means of temporary power-off. Background technique [0002] Traditionally, electrical appliances with a remote control are equipped with a remote control signal receiving circuit, so that the electrical appliance can receive the remote control signal from the remote control, and convert the remote control signal into a remote control function. [0003] Although it is convenient to use the remote control to control the electrical appliances, the remote control is easy to lose, and the battery needs to be disassembled, which in turn leads to the inconvenience of controlling the electrical appliances by the remote control. Contents of the invention [0004] In view of the shortcomings of the prior art, the inventor researched a solution to the above-mentioned shortcomings, and develop...
