If the specific posture changes, the directional indications will also change accordingly.

[0042] In addition, the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0043] In the prior art, an automated switch for a breeding door device has emerged, but this automatic switch for the breeding door is limited to the simple opening and closing of the door, and its functions are relatively single.

[0044] The present utility model provides a control circuit for a breeding door device.

[0045] Please refer to Figure 1 , in an embodiment of the present utility model, the breeding door device includes a door main body and a motor MT for driving the door main body to move. The control circuit for the breeding door device includes:

[0046] A trigger circuit 01, which is used to output a corresponding trigger signal when triggered by a user;

[0047] Light intensity detection circuit 02, which is used to detect the ambient light intensity and output a corresponding light detection signal;

[0048] Drive circuit 03, which is used to drive the motor MT;

[0049] Control circuit 04, which is respectively connected to the trigger circuit 01, the light intensity detection circuit 02 and the drive circuit 03;

[0050] Control circuit 04 is used to control the drive circuit 03 to drive the motor MT to drive the door body to open / close according to the light detection signal and the trigger signal.

[0051] It should be noted that during the day, the intensity of light such as infrared rays in the ambient light is relatively high, while at night, the intensity of light such as infrared rays in the ambient light is relatively low. In this embodiment, an ambient light intensity threshold can be set. When the intensity of the ambient light is higher than the ambient light intensity threshold, it is judged as day, and when the intensity of the ambient light is lower than the ambient light intensity threshold, it is judged as night. Taking raising chicks as an example, the door body can be controlled to open during the day and closed at night. Then the chicks can go out to forage during the day and return to the farm to rest at night. In this way, automatic breeding can be realized without manual control of the opening / closing of the breeding door device.

[0052] It should be noted that this embodiment includes a light control mode and a timing mode, and the user can select to enter different modes through the trigger circuit 01. In the light control mode, the light intensity detection circuit 02 detects the ambient light intensity and outputs a corresponding light detection signal. The control circuit 04 can judge whether it is day or night according to the light detection signal. For example, when the voltage of the light detection signal is greater than or equal to the preset voltage, it can be judged that the intensity of the ambient light is higher than the ambient light intensity threshold and is correspondingly judged as day, and the drive circuit 03 is controlled to drive the motor MT to drive the door body to open. When the voltage of the light detection signal is less than the preset voltage, it can be judged that the intensity of the ambient light is lower than the ambient light intensity threshold and is correspondingly judged as night, and the drive circuit 03 is controlled to drive the motor MT to drive the door body to close. In the timing mode, the user can input a timing opening signal or a timing closing signal through the trigger circuit 01. Among them, the timing opening signal includes a first preset time, and after the first preset time, the control circuit 04 can control the drive circuit 03 to drive the motor MT to drive the door body to open. The timing closing signal includes a second preset time, and after the second preset time, the control circuit 04 can control the drive circuit 03 to drive the motor MT to drive the door body to close. In this way, this embodiment includes a light control mode and a timing mode, which can realize the automatic opening / closing of the breeding door device when the user is out, facilitating the user's breeding control and solving the problem that the control of the existing automatic switch breeding door is relatively single.

[0053] Please refer toFigure 2 , in this embodiment, the control circuit 04 may include a control chip U4, an eighth capacitor C8, a ninth capacitor C9, a tenth capacitor C10, and a crystal oscillator YP. The crystal oscillator YP can generate a clock signal for timing. After a preset time, the control chip U4 can control the drive circuit 03 to drive the motor MT to drive the door body to open / close.

[0054] The present utility model may include a light control mode and a timing mode. The user can select to enter different modes through the trigger circuit 01. In the light control mode, the light intensity detection circuit 02 detects the ambient light intensity and outputs a corresponding light detection signal. The control circuit 04 can determine whether it is day or night according to the light detection signal. For example, when the voltage of the light detection signal is greater than or equal to the preset voltage, it can be determined that the intensity of the ambient light is higher than the ambient light intensity threshold, and it is correspondingly determined as day, and the drive circuit 03 is controlled to drive the motor MT to drive the door body to open. When the voltage of the light detection signal is less than the preset voltage, it can be determined that the intensity of the ambient light is lower than the ambient light intensity threshold, and it is correspondingly determined as night, and the drive circuit 03 is controlled to drive the motor MT to drive the door body to close. In the timing mode, the user can input a timing open signal or a timing close signal through the trigger circuit 01. Among them, the timing open signal includes a first preset time. After the first preset time, the control circuit 04 can control the drive circuit 03 to drive the motor MT to drive the door body to open. The timing close signal includes a second preset time. After the second preset time, the control circuit 04 can control the drive circuit 03 to drive the motor MT to drive the door body to close. In this way, the present utility model includes a light control mode and a timing mode, which can realize the automatic opening / closing of the breeding door device when the user goes out, facilitating the user's breeding control and solving the problem of the relatively single control of the existing automatic switch breeding door.

[0055] Please refer to Figure 2 , in an embodiment of the present utility model, the trigger circuit 01 includes:

[0056] A first key circuit, the first end of the first key circuit is connected to the control circuit 04, and the second end of the first key circuit is grounded;

[0057] The first key circuit is used to output a light detection enable control signal or a light detection disable control signal when triggered by the user;

[0058] A second key circuit, the first end of the second key circuit is connected to the control circuit 04, and the second end of the second key circuit is grounded;

[0059] The second key circuit is used to output a timing open control signal or a timing close control signal when triggered by the user;

[0060] Among them, the trigger signals include a light detection start control signal, a light detection stop control signal, a timed door opening control signal, and a timed door closing control signal.

[0061] In this embodiment, the first button circuit is specifically the first button K1, and the second button circuit is specifically the second button K2. In this embodiment, when the first button K1 or the second button K2 is pressed by the user, a low level is input to the control circuit.

[0062] In this embodiment, the trigger logic of the first button K1 and the second button K2 can be set. For example, it can be set that when the first button K1 is long-pressed by the user, a light detection start control signal is output. When the first button K1 is short-pressed by the user, a light detection stop control signal is output. Another example, it can be set that when the second button K2 is long-pressed by the user once, a timed door opening control signal is output, specifically: long-pressing once enters the setting of timed door opening, with a half-hour period, and each short-press increases the timed door opening time by half an hour until the timed time is automatically locked when there is no operation within the preset time. At this time, the control circuit 04 can obtain this timed time, which is the timed door opening control signal. When the second button K2 is long-pressed by the user twice, a timed door closing control signal is output, specifically: long-pressing twice enters the setting of timed door closing, with a half-hour period, and each short-press increases the timed door closing time by half an hour until the timed time is automatically locked when there is no operation within the preset time. At this time, the control circuit 04 can obtain this timed time, which is the timed door closing control signal. It can be understood that the interval period of the timed time can be set according to specific situations, for example, it can be ten minutes, twenty minutes, etc. Similarly, the time interval of the long-press can also be set according to specific situations, for example, pressing for a time greater than or equal to 3 seconds is a long-press, and less than that is a short-press.

[0063] It should be noted that the control circuit of the breeding door device may further include a prompting circuit for prompting the user about the trigger status of the control circuit of the breeding door device, specifically, it can prompt the light control mode or the timed mode, the remaining timed time, etc. For example, the prompting circuit can include an electronic digital tube for display.

[0064] In this embodiment, when the user triggers the output light detection start control signal, the light control mode is entered. In the light control mode, the light intensity detection circuit 02 detects the ambient light intensity and outputs a corresponding light detection signal. The control circuit 04 can determine whether it is day or night based on the light detection signal. When the user triggers the output timed door opening control signal or the timed door closing control signal, the timed mode is entered. It should be noted that the priority of the timed mode can be set higher than that of the light control mode, that is, in the timed mode, the drive circuit is no longer controlled according to the light detection signal. At this time, the control circuit 04 obtains the first preset time for opening the door according to the timed door opening control signal, starts timing, and controls the drive circuit 03 to drive the motor MT to drive the door body to open after the first preset time. Alternatively, the control circuit 04 obtains the second preset time for closing the door according to the timed door closing control signal, starts timing, and controls the drive circuit 03 to drive the motor MT to drive the door body to close after the second preset time.

[0065] Please refer to Figure 2 , in an embodiment of the present utility model, the control circuit of the breeding door device further includes an indicator light circuit 05, and the indicator light circuit 05 is connected to the control circuit 04;

[0066] The control circuit 04 is configured to control the operation of the indicator light circuit 05 according to the timed door opening control signal or the timed door closing control signal output by the second button circuit.

[0067] Among them, the indicator light circuit 05 includes a green light-emitting diode GL1, a red light-emitting diode RL1, a fifth resistor R5 and a sixth resistor R6; one end of the fifth resistor R5 is connected to the control circuit 04; the other end of the fifth resistor R5 is connected to the positive electrode of the green light-emitting diode GL1; one end of the sixth resistor R6 is connected to the control circuit 04; the other end of the sixth resistor R6 is connected to the positive electrode of the red light-emitting diode RL1; the negative electrodes of the green light-emitting diode GL1 and the red light-emitting diode RL1 are grounded.

[0068] In this embodiment, when the second button circuit outputs a timed door opening control signal, the control circuit 04 controls the green light-emitting diode GL1 to light up and the red light-emitting diode RL1 to go out. When the second button circuit outputs a timed door closing control signal, the control circuit 04 controls the red light-emitting diode RL1 to light up and the green light-emitting diode GL1 to go out. It can be understood that when setting the timed door opening by pressing and holding for a long time once, the green light-emitting diode GL1 can blink until the timed time is locked, that is, after the setting is completed, the green light-emitting diode GL1 remains constantly on. Similarly, when in the timed door closing setting state, the red light-emitting diode RL1 can blink until the timed time is locked, that is, after the setting is completed, the red light-emitting diode RL1 remains constantly on. In this way, this embodiment can effectively prompt the user of the current timed setting state of the control circuit of the breeding door device.

[0069] Please refer to Figure 2 In an embodiment of the present utility model, the light intensity detection circuit 02 includes a photosensitive diode CDS1 and a first resistor R1. One end of the photosensitive diode CDS1 is connected to the power input terminal of the light intensity detection circuit 02. The other end of the photosensitive diode CDS1 and one end of the first resistor R1 are connected to the control circuit 04, and the other end of the first resistor R1 is grounded.

[0070] In this embodiment, when the ambient light intensity is different, the voltage output by the photosensitive diode CDS1 is also different. The control circuit 04 can judge the current ambient light intensity according to the voltage output by the photosensitive diode CDS1, and then judge whether the current time is during the day or at night, so as to realize the opening / closing control of the door body.

[0071] Please refer to Figure 3 In an embodiment of the present utility model, the drive circuit 03 includes a first voltage regulator chip U1, a drive chip U2, a first triode Q1, a first PMOS transistor P1 and a second resistor R2;

[0072] Among them, the source electrode of the first PMOS transistor P1 and one end of the second resistor R2 are connected to the power input terminal of the drive circuit 03; the gate electrode of the first PMOS transistor P1 and the collector electrode of the first triode Q1 are connected to the other end of the second resistor R2; the base electrode of the first triode Q1 is connected to the control circuit 04; the emitter electrode of the first triode Q1 and the GND pin of the first voltage regulator chip U1 are grounded; the VIN pin of the first voltage regulator chip U1 is connected to the drain electrode of the first PMOS transistor P1; the VOUT pin of the first voltage regulator chip U1 is connected to the VDD pin of the drive chip U2; the INA pin of the drive chip U2 and the INB pin of the drive chip U2 are respectively connected to the control circuit 04; the OUTA pin of the drive chip U2 is connected to the first end of the motor MT; the OUTB pin of the drive chip U2 is connected to the second end of the motor MT.

[0073] In this embodiment, the control circuit 04 outputs control signals through the INA pin and the INB pin to control the forward and reverse rotation of the motor MT, corresponding to controlling the opening and closing of the door body. Among them, the control circuit 04 outputs a control signal through the EN pin. When the control signal is at a low level, the first triode Q1 is turned off, then the first PMOS transistor P1 is turned on. At this time, the first voltage regulator chip U1 inputs power, stabilizes the power supply and then outputs it to the drive chip U2. The drive chip U2 outputs a drive current to drive the motor MT to work, and drives the motor MT to rotate forward or reverse according to the signals of the INA pin and the INB pin. When the control signal is at a high level, the first triode Q1 is turned on, then the first PMOS transistor P1 is turned off. At this time, the first voltage regulator chip U1 cannot input power, and the drive motor MT stops working. Among them, the first voltage regulator chip U1 can be an LDO (Low Dropout Regulator) chip. In this way, this embodiment can drive the motor MT to drive the door body to work by controlling the drive circuit 03, and the first voltage regulator chip U1 is used for voltage regulation, and the stability of the drive circuit 03 is high.

[0074] Please refer to Figure 3 , in an embodiment of the present invention, the drive circuit 03 further includes a third resistor R3, a fourth resistor R4 and a first capacitor C1; one end of the third resistor R3, one end of the fourth resistor R4, the PGND pin and the AGND pin of the drive chip U2 are connected; the other end of the third resistor R3, the other end of the first capacitor C1 are connected to the control circuit 04; the other end of the first capacitor C1 and the other end of the fourth resistor R4 are grounded.

[0075] In this embodiment, the circuit composed of the third resistor R3, the fourth resistor R4 and the first capacitor C1 can detect whether the working state of the motor MT is abnormal. For example, when raising chicks, when the door body closes and clips a chick, the rotation of the motor MT is abnormal. Then, in order to drive the motor MT, the drive chip U2 needs to increase the drive current, and at this time the drive circuit is abnormal. The control circuit 04 can detect this abnormal situation through the circuit composed of the third resistor R3, the fourth resistor R4 and the first capacitor C1. At this time, a forward rotation signal can be output through the INA pin to control the door body to open completely and then close again to prevent the chick from being injured. In this way, this embodiment can prevent animals from being injured when entering and leaving the door.

[0076] Please refer to Figure 4 , in an embodiment of the present invention, the control circuit of the breeding door device further includes a battery BAT, a first diode D1, a second voltage regulator chip U3, a second capacitor C2 and a third capacitor C3;

[0077] Among them, the positive electrode of the battery BAT is connected to the positive electrode of the first diode D1; the negative electrode of the first diode D1 and one end of the second capacitor C2 are connected to the VIN pin of the second voltage regulator chip U3; the VOUT pin of the second voltage regulator chip U3, one end of the third capacitor C3, and the power input terminal of the control circuit 04 are connected to the power input terminal of the light intensity detection circuit 02; the GND pin of the second voltage regulator chip U3 and the other end of the second capacitor C2 are grounded together with the other end of the third capacitor C3.

[0078] In this embodiment, the battery BAT can output power. The diode can prevent the subsequent circuit from being damaged by reverse current. The second voltage regulator chip U3 can regulate the voltage output by the battery BAT and then output it to the control circuit 04 and the light intensity detection circuit 02. Among them, the second capacitor C2 and the third capacitor C3 can be used for filtering and voltage regulation. In this way, in this embodiment, the voltage of the input power supply of the control circuit 04 and the light intensity detection circuit 02 is relatively stable, which can protect the normal operation of the circuit.

[0079] Please refer to Figure 3 , in an embodiment of the present invention, the drive circuit 03 further includes a fourth capacitor C4, a fifth capacitor C5, a sixth capacitor C6, a seventh capacitor C7, and a seventh resistor R7;

[0080] Among them, one end of the fourth capacitor C4 is connected to the first end of the motor MT; the other end of the fourth capacitor C4 is connected to the second end of the motor MT; one end of the fifth capacitor C5 and one end of the sixth capacitor C6 are connected to the VOUT pin of the first voltage regulator chip U1; one end of the seventh capacitor C7 is connected to the VIN pin of the first voltage regulator chip U1; the other end of the fifth capacitor C5, the other end of the sixth capacitor C6, and the other end of the seventh capacitor C7 are grounded; one end of the seventh resistor R7 is connected to the control circuit 04; the other end of the seventh resistor R7 is connected to the base of the first triode Q1.

[0081] In this embodiment, the seventh resistor R7 can be used for current limiting and voltage division.
