Problems solved by technology
[0002] In heating and other fields, heating companies generally install room temperature controllers in users' homes in order to count the actual heating effect. Room temperature controllers generally have two power supply methods: battery power supply, single live wire power supply, and single live wire power supply because they can replace mechanical switches. , can be well installed in the original 86 box position, so the room temperature controller powered by single live wire has gradually become popular, but the room temperature controller powered by single live wire has a disadvantage, when the user's lamps are dual-controlled, it cannot be used. cost of the room temperature controller instead of
[0003] In the prior art, the double control of the room temperature controller to the user's electrical appliances is generally realized by means of inverters and other methods. In this method, when the lights are turned off, when the power is turned on again after a power failure, the user's electrical appliances or lights have a 50% probability It will always be on, causing waste and poor user experience

Embodiment Construction
[0041] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0042] Such as figure 1 with 3 As shown, a dual-control control circuit is used to perform dual-control control on the first electrical appliance 10, which is characterized in that it includes:
[0043] The first single-chip microcomputer 50 has a first switch pin KEY1, a first power-on pin AC1, a second power-on pin AC2, and a first control pin IN1;
[0044] The first electrical appliance 10, which includes a first electrical appliance body 11 and a first relay 12 for controlling the switch of the first electrical appliance, the first relay has a first control terminal electrically connected to the first control pin IN1;
[0045] The first power supply circuit 20 includes a first single-pole double-throw switch SPDT1, a diode D1, and a diode D2. The first single-pole double-throw switch has a first terminal K1 and a second terminal K2; the ...

The invention discloses a double-control control circuit and a control method. The circuit comprises a single-chip microcomputer, a first power supply circuit comprising a first single-pole double-throw switch SPDT1, a diode D1 and a diode D2, a first t power-on detection circuit and a second t power-on detection circuit, wherein the first single-pole double-throw switch comprises a first terminalK1 and a second terminal K2, the first terminal is electrically connected with one end of a first relay through the diode D1, the second terminal is electrically connected with one end of a second relay through the diode D2, the other end of the first relay is grounded, the first power-on detection circuit is used for detecting the power-on condition of the first terminal, and the second power-ondetection circuit is used for detecting the power-on condition of the second terminal. The double-control detection circuit is advantaged in that the double-control detection circuit is low in cost,can achieve a real double-control function in cooperation with a control method, cannot cause a problem that a user lamp is normally on after power failure, adapts to an installation site, and is convenient to maintain.
