Summary of the Invention

[0003] An automatic energy-saving controller for incubator lamps for breeding is provided to overcome the deficiencies of the prior art. It can not only solve the technical problem of poor timeliness caused by untimely manual adjustment and setting of temperature, but also solve the technical problem of energy waste caused by the inability to turn on and off the incubator lamp in time.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions. An automatic energy-saving controller for incubator lamps for breeding includes a temperature controller, which includes a single-chip microcomputer controller and a plastic shell. The single-chip microcomputer controller mainly consists of a CPU control circuit, a display circuit, a temperature detection circuit, a key circuit, a microwave radar sensor circuit, a thyristor output circuit, and a power conversion circuit.

[0005] The CPU control circuit is the core part of the system, receiving signals from various sensors and processing them, and at the same time sending control signals to the thyristor output circuit and the display circuit.

[0006] The display circuit is used to display parameters such as measured temperature, set temperature, and entry time, and uses digital tubes.

[0007] The temperature detection circuit is used to control and adjust the heating or stopping of the incubator lamp, and includes a temperature sensor, which uses a thermistor to measure temperature.

[0008] The key circuit is used to operate the temperature controller.

[0009] The microwave radar sensor circuit uses microwave radar induction to detect whether there are animals in the pen and when the animals enter the pen, and transmits the signal to the CPU control circuit, including a microwave radar sensor.

[0010] The thyristor output circuit uses a thyristor for output control to control the heating or stopping of the incubator lamp, and includes a solid-state relay.

[0011] The power conversion circuit is used to convert alternating current 220V into direct current 5V.

[0012] Further, the output end of the power conversion circuit is electrically connected to the input end of the CPU control circuit respectively, the output ends of the microwave radar sensor circuit, the temperature detection circuit, and the key circuit are electrically connected to the input end of the CPU control circuit respectively, the input end of the display circuit is electrically connected to the output end of the CPU control circuit, and the input end of the thyristor output circuit is electrically connected to the output end of the CPU control circuit.

[0013] Preferably, the digital tube of the display circuit is replaced with an LCD screen.

[0014] Further, the key circuit includes three keys, namely the power on / off key for controlling the thermostat host, the up / down adjustment key, and the intelligent switching key.

[0015] Further, the single-chip microcomputer controller further includes an infrared remote control circuit for remotely controlling the turning on and off of the heat preservation lamp by a remote controller.

[0016] Further, the infrared remote control circuit is signal-connected to the CPU control circuit.

[0017] A method for realizing an automatic energy-saving controller for a breeding heat preservation lamp is as follows:

[0018] S1: The single-chip microcomputer controller is divided into two control modes, namely the manual mode and the intelligent mode, and can be switched between the two modes through the keys on the controller;

[0019] S2: When switched to the manual mode, in this mode, it is necessary to manually set the environmental temperature value that you want to achieve. The thermostat detects the environmental temperature and compares it with the environmental temperature value that you want to achieve, controls the heating and stopping of the heat preservation lamp. The microwave radar constantly detects whether there are animals in the pen. If it detects the presence, the controller works normally. If not, the heat preservation lamp is turned off;

[0020] S3: When switched to the intelligent mode, in this mode, the user first sets the cycle days between entering the pen and leaving the pen according to the actual situation of the breeding animals, and can set the environmental temperature when entering the pen and the environmental temperature when leaving the pen. The thermostat intelligently identifies the animals entering the pen through the microwave radar sensor and records the time, and starts to execute the internal algorithm to accurately adjust the environmental temperature; when the cycle ends, if the microwave radar sensor does not detect animals in the pen for 2 consecutive hours, it is considered that the animals have left the pen, and the heat preservation lamp is automatically turned off. After the animals entering the pen are identified again, the cycle of controlling the temperature will start again.

[0021] Further, the internal algorithm in S3 is specifically as follows:

[0022] Set the desired ambient temperature T1 when the animals enter the pen, the desired ambient temperature when they leave the pen is T2, the cycle days is D, and the cumulative time T3 is counted from when the microwave radar detects the animals entering the pen. The final ambient temperature T obtained currently is T = T1 - (T1 - T2) / (D * 24) × T3.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] The present invention uses a microwave radar to sense whether there are animals in the pen and automatically controls the brightness of the heat preservation lamp according to the entry time, making the temperature curve in the breeding process more suitable for the growth or reproduction of animals, thereby improving the breeding efficiency and saving electric energy.

[0035] Embodiment 1

[0036] As Figures 1 to 8As shown in the figure, an automatic energy-saving controller for a breeding heat preservation lamp includes a temperature controller. The temperature controller includes a single-chip microcomputer controller and a plastic shell. The single-chip microcomputer controller mainly consists of a CPU control circuit, a display circuit, a temperature detection circuit, a key circuit, a microwave radar sensor circuit, a thyristor output circuit, a power conversion circuit, and an infrared remote control circuit. The power conversion circuit is used to convert AC 220V into DC 5V and then supply it to the CPU control circuit. The CPU control circuit is the core part of the system, receiving signals from various sensors and processing them, and at the same time sending control signals to the thyristor output circuit and the display circuit. The display circuit is used to display parameters such as the measured temperature, set temperature, and entry time, using a digital tube or an LCD screen. The temperature detection circuit is used to control and adjust the heating or stopping of the heat preservation lamp, including a temperature sensor, and the temperature sensor uses a thermistor to measure temperature. The key circuit includes three keys, namely the power on / off key for controlling the main unit of the temperature controller, the up / down adjustment key, and the intelligent switching key, which are used to operate the switch and mode switching of the temperature controller. The microwave radar sensor circuit uses microwave radar induction to detect whether there are animals in the pen and when the animals enter the pen, and transmits the signal to the CPU control circuit, including a microwave radar sensor. The thyristor output circuit uses a thyristor for output control to control the heating or stopping of the heat preservation lamp, including a solid-state relay. The single-chip microcomputer controller also includes an infrared remote control circuit for controlling the opening and closing of the heat preservation lamp by a remote control.

[0037] Specifically, the output end of the power conversion circuit is electrically connected to the input end of the CPU control circuit respectively. The output ends of the microwave radar sensor circuit, the temperature detection circuit, and the key circuit are electrically connected to the input end of the CPU control circuit respectively. The input end of the display circuit is electrically connected to the output end of the CPU control circuit. The input end of the thyristor output circuit is electrically connected to the output end of the CPU control circuit. The infrared remote control circuit is signal-connected to the CPU control circuit.

[0038] The implementation method of the above-mentioned automatic energy-saving controller for a breeding heat preservation lamp is an automatic recognition and adjustment method for breeding temperature based on microwave radar induction technology, which is specifically as follows:

[0039] S1: The single-chip microcomputer controller is divided into two control modes: manual mode and intelligent mode, and can be switched between the two modes through the keys in the controller.

[0040] S2: When switched to the manual mode, in this mode, it is necessary to manually set the environmental temperature value that you want to reach. The temperature controller detects the environmental temperature and compares it with the environmental temperature value that you want to reach, and controls the heating and stopping of the heat preservation lamp. The microwave radar constantly detects whether there are animals in the pen. If it detects that there are animals, the controller works normally. If there are no animals, the heat preservation lamp is turned off to avoid wasting energy.

[0041] S3: When switching to the intelligent mode, in this mode, the user first sets the cycle days between the entry and exit of the breeding animals according to the actual situation of the animals, and can set the environmental temperature desired at the time of entry and the environmental temperature desired at the time of exit. The thermostat uses a microwave radar to intelligently identify the entry of animals and records the time, and then starts to execute the internal algorithm to accurately adjust the environmental temperature. When the cycle ends, if the microwave radar fails to identify any animals in the pen for 2 consecutive hours, it is considered that the animals have exited the pen, and the heating lamp will be automatically turned off. After the animals are identified as entering the pen again, the cycle of controlling the temperature will start again.

[0042] The relevant algorithm for the intelligent mode is as follows:

[0043] Set the environmental temperature T1 desired at the time of entry, the environmental temperature T2 desired at the time of exit, the cycle days as D, and the cumulative time T3 from when the microwave radar identifies the entry of animals. The final environmental temperature T obtained currently is T = T1 - (T1 - T2) / (D * 24) × T3.
