Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, the present invention provides a photosensitive induction control circuit, which includes a light detection circuit 1, an induction circuit 2, a main control circuit 3, a control signal transmitting circuit 4 and at least one relay circuit 5.
The main control circuit 3 is connected to the light detecting circuit 1 to receive the detection signal. Specifically, the light detection circuit 1 is configured to generate a detection signal representing the intensity of light according to the intensity of light in the environment, and it can be understood that the current day and night condition can be determined according to the detection signal.
The main control circuit 3 is connected with the sensing circuit 2 to receive the sensing signal thereof. Specifically, the sensing circuit 2 is used for sensing whether a person is in an action range of the sensing circuit and generating a sensing signal which can represent the presence or absence of the person.
The main control circuit 3 is connected with the control signal transmitting circuit 4 so as to transmit a control signal capable of controlling the electric appliance to be turned on or turned off through the control signal transmitting circuit 4 according to the detection signal and the induction signal. Specifically, the control signal can control the on or off of various types of electrical appliances (such as an air conditioner, an exhaust fan and the like); take the example of a photosensitive induction type control circuit controlling the air conditioner in a room; the main control circuit 3 determines whether to control the air conditioner to be turned on or off (turned on when someone exists and turned off when no one exists) according to the received sensing signal; when no person is detected in the room through the induction signal, the fact that the user possibly leaves the room in a short time is considered, if the air conditioner is immediately turned off, the temperature of the user when the user returns to the room is possibly deviated from the comfortable temperature range of the human body, and in order to improve user experience, when no person is detected in the confirmation room, a control signal capable of controlling the air conditioner to be turned off can be sent out after a period of time is delayed; because the sunlight density in the daytime is high, the temperature is relatively high at night, and the temperature rises quickly, the current day and night condition can be judged by the main control circuit 3 according to the received detection signal, and the set delay time in the daytime is longer than the set delay time in the evening.
The main control circuit 3 is connected to each relay circuit 5 to receive control instructions from other control devices via the relay circuit 5. Specifically, for some application scenes with large area, because the transmission signal action range of some control devices is limited, the risk that relatively distant electric appliances cannot be controlled exists, the relay circuit 5 correspondingly processes and transmits the control instruction to the main control circuit 5 after receiving the control instruction sent by other control devices, and the main control circuit 5 transmits the control instruction through the control signal transmitting circuit 4, which is equivalent to adding the transmission signal action range of the control signal transmitting circuit 4 to the control devices, even if the control instruction realizes the expansion of the control range; the arrangement of a plurality of relay circuits 5 can expand the range of receiving control commands; in addition, the control device may be a device including the photosensitive inductive control circuit provided by the embodiment of the present invention, or a control device such as a remote controller.

Referring to fig. 2, the light detecting circuit 1 operates as follows: based on that the resistance of the first photo-resistor R3 changes with the light intensity of the environment where the first photo-resistor R3 is located, the voltage division ratio between the second resistor R2 and the first photo-resistor R3 changes accordingly, and therefore the light intensity of the environment can be represented by detecting the voltage (i.e., the detection signal) at the first end of the first photo-resistor R3.
