Problems solved by technology
However, for those who work on the move, such as suppliers, business salesmen, etc., it is impossible to determine the time to go home, so it is useless to start the cooking function of the rice cooker at regular intervals, because when the meal is ready, it may be cold and the person has not returned home, which is a waste of time

The invention discloses an electronic remote random controller, and belongs to an electronic device capable of controlling a power supply of an electrical appliance to be switched on / off through a ringing signal of a mobile phone or a table phone. The electronic remoter random controller mainly comprises a phone receiver for leading in a telephone signal, an integral sampler, a comparative judgment device and a changeover controller which are sequentially cascaded with one another. A direct-current working power supply is formed by cascading a transformer in which 220V alternating current is led with a rectification filtering voltage stabilizing circuit; the electrical appliance and a normally-open contact of a relay J2 are connected in series with each other in a transformer primary coil loop; and the integral sampler is formed by an operational amplifier. When the electronic remote random controller is used, the ringing signal is generated by the mobile phone or the table phone; a control signal is transmitted when the ringing signal is determined to be a work instruction through sampling and comparative judgment; and the power supply of the electrical appliance is controlled to be switched on / off through the relay. The electronic remote random controller has the characteristics that the controller is novel in design, convenient and practical, has a simple structure, and the like.
Description
technical field [0001] The invention relates to a remote controller for starting and stopping a power supply of an electric appliance, in particular to an electronic device for controlling the starting and stopping of the power supply of a home or office or industrial electric appliance through the ringing signal of a mobile phone or a landline. Background technique [0002] In industrial and household electrical appliances, there are several devices that need to be operated and controlled remotely. Through such operation and control, the efficiency can be improved, energy can be saved, and safety can be enhanced. Below, we take the rice cooker as an example to illustrate. The rice cooker can cook rice, steam vegetables, and cook soup, and has an automatic trip function for dry pots, so it is a very good household appliance. In addition, some of them now have time control, and the technical content has been further improved. However, for those who are in the work flow, suc...
