Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of circuit design, and particularly to a control circuit for realizing power-on triggering and automatic power-off locking. Background Technology

[0002] The current controller's internal power supply is typically switched on immediately when the external power is connected, making the controller susceptible to external interference and prone to malfunctions. Furthermore, the controller does not shut off its internal power after an action command is executed, resulting in high standby power consumption and significant heat generation, and it cannot completely prevent malfunctions during standby. Disconnecting the controller from the external power supply requires repeatedly switching it on and off, which is cumbersome. Utility Model Content

[0003] The purpose of this utility model is to provide a control circuit for realizing power-on triggering and automatic power-off locking, so as to solve the problem that the internal power connection of the existing controller will cause it to malfunction due to external interference; and the controller also has problems such as large standby power consumption, serious heat generation and inability to completely avoid malfunction during standby.

[0004] The technical solution of this utility model is as follows: This utility model provides a control circuit for realizing power-on triggering and automatic power-off locking, including: a logic OR sub-circuit, a level conversion sub-circuit, and a power switch sub-circuit;

[0005] Among them, the action command signal terminal A and the action completion feedback terminal B of the working circuit are connected to the input terminal of the logic OR sub-circuit. The output terminal of the logic OR sub-circuit is connected to the input terminal of the level conversion sub-circuit. The drain D of the N-channel field-effect transistor Q11 at the end of the level conversion sub-circuit is connected to the external power supply, and the source S is connected to the ground. The external power supply and the internal power supply of the controller are directly connected in series with the power switch sub-circuit. The source S of the P-channel field-effect transistor Q7 in the power switch sub-circuit is connected to the external power supply, and the drain D and the internal power supply are both connected to ground.

[0006] The control circuit is used to prevent the external power supply from being connected to the internal power supply after the external power supply is powered on, based on the field-effect transistor Q set in the power switch sub-circuit; when the action command signal terminal A outputs the action command signal, it outputs a high level through the logic OR sub-circuit, turns on the field-effect transistor Q11 in the level conversion sub-circuit, thereby turning on the field-effect transistor Q7 in the power switch sub-circuit, thereby connecting the external power supply and the internal power supply of the controller, and executing the command action.

[0007] The control circuit is also used to output a low level through the action completion feedback terminal B after the controller's instruction action is completed, and output a low level through the logic OR sub-circuit to disconnect the field-effect transistor Q11 in the level conversion sub-circuit, thereby disconnecting the field-effect transistor Q7 in the power switch sub-circuit, so that the power supply inside the controller is cut off.

[0008] Optionally, in the control circuit described above for implementing power-on triggering and automatic power-off locking, the logic or sub-circuit includes: diode D18 and diode D21;

[0009] After the action is completed, the feedback terminal B is connected to the positive terminal of diode D18, the action command signal terminal A is connected to the positive terminal of diode D21, and the negative terminals of diodes D18 and D21 are connected in parallel to the input terminal of the level conversion sub-circuit.

[0010] The control circuit is used to output an action command signal at the action command signal terminal A, that is, when the output is high level, it outputs a high level through the logic OR sub-circuit output terminal, turns on the field-effect transistors Q11 and Q7, thereby turning on the external power supply and the internal power supply; and after the action is completed and the action command signal is output at the feedback terminal B, the action command signal terminal A continues to output a high level to continuously turn on the external power supply and the internal power supply of the controller.

[0011] The control circuit is also used to output a low level through the logic OR sub-circuit output terminal when the feedback terminal B outputs a low level after the action is completed, thereby disconnecting the field-effect transistors Q11 and Q7 in the subsequent circuit, thus disconnecting the external power supply and the internal power supply, and causing the internal power supply of the controller to be de-energized.

[0012] Optionally, in the control circuit described above for realizing power-on triggering and automatic power-off locking, the level conversion sub-circuit includes: resistor R79, resistor R84, capacitor C47, Zener diode DZ7, and N-channel MOSFET Q11.

[0013] The output of the logic or sub-circuit is connected to one end of resistor R84 and capacitor C47, the negative terminal of Zener diode D27, and the gate G of field-effect transistor Q11 via resistor R79; the other end of resistor R84 and capacitor C47, the positive terminal of Zener diode DZ7 and the source S of field-effect transistor Q11 are connected to ground, and the drain D of N-channel field-effect transistor Q11 is connected to an external power supply.

[0014] The power switch sub-circuit includes: a Zener diode DZ6 and a P-channel MOSFET Q7;

[0015] The negative terminal of Zener diode DZ6 and the source S of MOSFET Q7 are connected to the external power supply, the positive terminal of Zener diode DZ6 is connected to the gate G of MOSFET Q7, the drain D of MOSFET Q7 is connected to the internal power supply of the controller, and the drain D is connected to ground through current limiting resistor R86.

[0016] Optionally, in the control circuit described above for implementing power-on triggering and automatic power-off locking,

[0017] The control circuit connects the external power supply and the controller's internal power supply in the following way: When the logic OR sub-circuit outputs an action command signal at the action command signal terminal A, the level conversion sub-circuit converts the high level at its input terminal to the low level output at the drain D of the field-effect transistor Q11. This allows the external power supply to reach the drain D of the field-effect transistor Q11 through the Zener diode DZ6 of the power switch sub-circuit, and to conduct the path from the drain D and source S of the field-effect transistor Q11 to ground. This, in turn, conducts the path from the external power supply through the field-effect transistor Q7 and the internal power supply to ground, thus enabling the controller's internal power supply to be turned on and execute the command action. During the execution of the command action by the controller, the action completion feedback terminal B outputs a high level to maintain the controller's internal power supply on.

[0018] Optionally, the control circuit described above for realizing power-on triggering and automatic power-off locking further includes: a discharge circuit;

[0019] The discharge circuit is connected between the level conversion sub-circuit and the power switch sub-circuit. When the feedback terminal B outputs a low level after the action is completed, the field-effect transistor Q11 is turned off. The discharge circuit's capacitor discharge function causes the field-effect transistor Q7 to turn off after a delay, thereby delaying the disconnection of the controller's internal power supply from the external power supply after the controller's command action is completed.

[0020] Optionally, in the control circuit described above for realizing power-on triggering and automatic power-off locking, the discharge circuit includes: resistor R66, resistor R69, capacitor C38 and capacitor C39.

[0021] Among them, resistor R66 is connected between the external power supply and the drain D of field-effect transistor Q11, resistor R69 is connected between the drain D of field-effect transistor Q11 and the gate G of field-effect transistor Q7, and capacitors C38 and C39 are connected in parallel with Zener diode DZ6.

[0022] The beneficial effects of this utility model are as follows: This utility model provides a control circuit for realizing power-on triggering and automatic power-off locking. The scheme for realizing the power supply on and off of the controller using this control circuit is as follows: After the external power supply is powered on, the internal power supply of the controller will not be powered on immediately. Only after receiving the action command issued by the action command signal terminal A will the internal power supply of the controller be triggered to power on and execute the action command. When the controller detects that the action command has been executed, it sends a low level through the action execution completion feedback terminal B to automatically cut off the power to the internal power supply of the controller and lock the state after the action execution is completed. In addition, after the action execution completion feedback terminal B sends a low level to disconnect the field-effect transistor Q11 in the level conversion sub-circuit, the discharge process of capacitors C38 and C39 in the discharge circuit will delay the disconnection time of the field-effect transistor Q7 used to cut off the power to the internal power supply of the controller, thereby ensuring that the action command of the controller is reliably executed. After Q7 is disconnected, the internal power supply of the controller is locked to lock the state after the action execution is completed. The control circuit provided in this embodiment of the utility model automatically collects working instructions and status signals indicating the completion of actions to realize the connection and disconnection of the internal power supply of the controller. This effectively prevents malfunctions in the standby state of the controller and significantly reduces the standby power consumption of the controller. It eliminates the need for frequent external operation to disconnect and connect the power supply, making it convenient to operate. Furthermore, the control circuit has a simple product structure, high reliability, and low cost, thus it is highly practical, easy to promote and apply, and has significant practical value.

[0023] The accompanying drawings are provided to further illustrate the technical solution of this utility model and constitute a part of the specification. They are used together with the embodiments of this application to explain the technical solution of this utility model and do not constitute a limitation on the technical solution of this utility model.

[0024] Figure 1 This is a schematic diagram of an automatic switching circuit for timing control and real-time control of a brake, provided as an embodiment of the present invention. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0026] As explained in the background section, existing controllers suffer from problems due to their internal power supply configuration and the fact that they do not shut off power after an action command is completed. To address these issues, this invention provides a control circuit for implementing power-on triggering and automatic power-off locking.

[0027] The present invention provides the following specific embodiments, which can be combined with each other. For the same or similar concepts or processes, they will not be described again in some embodiments.

[0028] Figure 1 This is a schematic diagram of an automatic switching circuit for timing control and real-time control of a brake, provided as an embodiment of the present invention. This embodiment addresses the problems existing in the existing control logic of the controller by redesigning the controller's power-on circuit to meet the logic control effects achieved by fulfilling the internal power-on and power-off requirements of the controller.

[0029] Reference Figure 1 As shown, the control circuit for realizing power-on triggering and automatic power-off locking provided in this embodiment of the utility model mainly includes: a logic OR sub-circuit, a level conversion sub-circuit, and a power switch sub-circuit.

[0030] In this embodiment of the invention, the action command signal terminal A and the action completion feedback terminal B of the working circuit are connected to the input terminal of the logic OR sub-circuit. The output terminal of the logic OR sub-circuit is connected to the input terminal of the level conversion sub-circuit. The drain D of the N-channel field-effect transistor Q11 at the end of the level conversion sub-circuit is connected to the external power supply, and the source S is connected to the ground. The external power supply and the internal power supply of the controller are directly connected in series with a power switch sub-circuit. The source S of the P-channel field-effect transistor Q7 in the power switch sub-circuit is connected to the external power supply, and the drain D and the internal power supply are both connected to ground.

[0031] Based on the structure of each sub-circuit in the control circuit provided by this utility model, the working principle of the control circuit includes:

[0032] After the external power supply is powered on, the field-effect transistor Q set in the power switch sub-circuit does not connect the external power supply and the internal power supply.

[0033] When the action command signal terminal A outputs the action command signal, it outputs a high level through the logic OR sub-circuit, turns on the field-effect transistor Q11 in the level conversion sub-circuit, and thus turns on the field-effect transistor Q7 in the power switch sub-circuit, thereby connecting the external power supply and the internal power supply of the controller, and executing the command action.

[0034] After the controller completes its command action, it outputs a low level through the action completion feedback terminal B, which in turn outputs a low level through the logic OR sub-circuit, turning off the field-effect transistor Q11 in the level conversion sub-circuit, thereby disconnecting the field-effect transistor Q7 in the power switch sub-circuit, thus de-energizing the controller's internal power supply.

[0035] In one implementation of this utility model embodiment, such as Figure 1 As shown, the logic OR sub-circuit in the control circuit provided by this utility model includes diode D18 and diode D21.

[0036] After the action is completed, feedback terminal B is connected to the positive terminal of diode D18, action command signal terminal A is connected to the positive terminal of diode D21, and the negative terminals of diodes D18 and D21 are connected in parallel to the input terminal of the level conversion sub-circuit.

[0037] This logic OR sub-circuit implements a logic OR function. When the action command signal terminal A outputs an action command signal, it briefly outputs a high level. Subsequently, based on circuit control requirements, the action completion feedback terminal B continuously outputs a high level after the action command signal terminal A outputs the action command signal. At this time, the action command signal terminal A outputs a low level, and the logic OR sub-circuit continuously outputs a high level to maintain the internal power supply of the controller to execute the command action. After the controller completes the command action, the action completion feedback terminal B outputs a low level, and the logic OR sub-circuit outputs a low level to cut off the external power supply and the internal power supply of the controller.

[0038] Accordingly, the specific working mode of the control circuit provided by this utility model is as follows:

[0039] When the action command signal is output at the action command signal terminal A, i.e., when the output is high, the logic OR sub-circuit output terminal outputs a high level, turning on the field-effect transistors Q11 and Q7, thereby turning on the external power supply and the internal power supply; and when the action is completed, the feedback terminal B continuously outputs a high level during the process of the internal power supply of the controller being turned on and the action being executed, so as to continuously turn on the external power supply and the internal power supply of the controller.

[0040] When the feedback terminal B outputs a low level after the action is completed, a low level is output through the logic OR sub-circuit output terminal, disconnecting the field-effect transistors Q11 and Q7 in the subsequent circuit, thereby disconnecting the external power supply and the internal power supply, and causing the controller to power off.

[0041] In one implementation of this utility model embodiment, such as Figure 1 As shown, the level conversion sub-circuit includes: resistor R79, resistor R84, capacitor C47, Zener diode DZ7, and N-channel MOSFET Q11. The output of the above logic OR sub-circuit is connected via resistor R79 to one end of resistor R84 and capacitor C47, the cathode of Zener diode D27, and the gate G of MOSFET Q11. The other ends of resistor R84 and capacitor C47, the anode of Zener diode DZ7, and the source S of MOSFET Q11 are connected to ground, and the drain D of N-channel MOSFET Q11 is connected to an external power supply.

[0042] In addition, such as Figure 1As shown, the power switch sub-circuit includes a Zener diode DZ6 and a P-channel MOSFET Q7. The cathode of the Zener diode DZ6 and the source S of the MOSFET Q7 are connected to an external power supply, the anode of the Zener diode DZ6 is connected to the gate G of the MOSFET Q7, and the drain D of the MOSFET Q7 is connected to the internal power supply of the controller. The drain D is also connected to ground via a current-limiting resistor R86.

[0043] It should be noted that in this embodiment of the invention, the Zener diode DZ6 has a Zener voltage value based on the V of the P-channel MOSFET Q7. GS Designed, for example, the V of the P-channel MOSFET Q7 GS The voltage regulation value of the Zener diode DZ6 can be designed from 10V to 16V, with a range of 8V to 20V.

[0044] In this implementation, the control circuit connects the external power supply and the controller's internal power supply as follows: When the logic or sub-circuit outputs an action command signal at the action command signal terminal A, the level conversion sub-circuit converts the high level at its input terminal to the low level output at the drain D of the field-effect transistor Q11. This allows the external power supply to reach the drain D of the field-effect transistor Q11 through the Zener diode DZ6 of the power switch sub-circuit, and to conduct the path from the drain D and source S of the field-effect transistor Q11 to ground. This, in turn, conducts the path from the external power supply through the field-effect transistor Q7 and the internal power supply to ground, thus enabling the controller's internal power supply to be turned on and the command action to be executed. During the execution of the command action by the controller, the action completion feedback terminal B outputs a high level to maintain the controller's internal power supply on.

[0045] Furthermore, the control circuit provided in this embodiment of the present invention may further include: a discharge circuit; the discharge circuit is connected between the level conversion sub-circuit and the power switch sub-circuit, and is used to delay the disconnection of the field-effect transistor Q7 by the capacitor discharge function of the discharge circuit after the field-effect transistor Q11 is turned off when the feedback terminal B outputs a low level after the action is completed. This delays the disconnection of the internal power supply and the external power supply of the controller after the controller command action is completed.

[0046] In specific implementation, such as Figure 1 As shown, the discharge circuit includes: resistor R66, resistor R69, capacitor C38, and capacitor C39; wherein, resistor R66 is connected between the external power supply and the drain D of field-effect transistor Q11, resistor R69 is connected between the drain D of field-effect transistor Q11 and the gate G of field-effect transistor Q7, and capacitors C38 and C39 are connected in parallel with Zener diode DZ6.

[0047] The control circuit provided in this embodiment of the utility model disconnects the internal power supply from the external power supply by setting a field-effect transistor Q7. It collects whether there is a working command and only connects the internal power supply of the controller to the external power supply when there is a working command to execute the working command. After the working command is detected to be executed, the internal power supply of the controller is disconnected from the external power supply through a capacitor delay, which significantly reduces the standby power consumption of the controller and reduces the risk of controller malfunction, and can be adapted to different occasions.

[0048] This utility model embodiment provides a control circuit for implementing power-on triggering and automatic power-off locking. The scheme for controlling the internal power supply of the controller using this control circuit is as follows: after the external power supply is powered on, the controller's internal power supply will not be powered on immediately. Only after receiving an action command issued by the action command signal terminal A will the controller's internal power supply be triggered to power on and execute the action command. When the controller detects that the action command has been executed, it sends a low level through the action completion feedback terminal B to automatically power off the controller's internal power supply, locking the state after the action execution is completed. Furthermore, after the action completion feedback terminal B sends a low level, causing the field-effect transistor Q11 in the level conversion sub-circuit to disconnect, the discharge process of capacitors C38 and C39 in the discharge circuit will delay the disconnection time of the field-effect transistor Q7, which is used to cut off the power supply to the controller's internal power supply. This ensures that the controller's action command is reliably executed, and after Q7 disconnects, the controller's internal power supply is locked, locking the state after the action execution is completed. The control circuit provided in this embodiment of the utility model automatically collects working instructions and status signals indicating the completion of actions to realize the connection and disconnection of the internal power supply of the controller. This effectively prevents malfunctions in the standby state of the controller and significantly reduces the standby power consumption of the controller. It eliminates the need for frequent external operation to disconnect and connect the power supply, making it convenient to operate. Furthermore, the control circuit has a simple product structure, high reliability, and low cost, thus it is highly practical, easy to promote and apply, and has significant practical value.

[0049] The following is an illustrative description of the implementation method of the control circuit for power-on triggering and automatic power-off locking provided by the present invention through an implementation example.

[0050] See Figure 1 As shown, the circuit structure of the control circuit provided in this embodiment is the same as that in the above embodiments, and therefore will not be described again here. The working principle of this control circuit is as follows:

[0051] +28V is the external power supply, and +28V1 is the internal power supply of the controller. Terminal A is the input of the action command signal, and terminal B is the flag input terminal after the action is completed (a low level indicates that the action is completed). After the external power supply is powered on, the internal +28V1 will not be immediately connected to the external power supply +28V. Instead, when the action command is received from terminal A, Q11 is turned on, and then Q7 is turned on, the controller is powered on internally, and the action command is executed.

[0052] After the action command is executed, terminal B outputs a low level, Q11 disconnects, and then Q7 disconnects after a delay, disconnecting the controller's internal power supply from the external +28V power supply, thus de-energizing the controller. By using parallel capacitors C38 and C39 to set the delay between Q11 disconnecting and Q7 disconnecting, reliable execution of the action command is ensured. After Q7 disconnects, the controller's internal power is de-energized, locking the action execution completed state. This control circuit significantly reduces the controller's standby power consumption and the risk of malfunction, eliminating the need for repeated external power switching and simplifying operation.

[0053] Although the embodiments disclosed in this utility model are as described above, the content is only for the purpose of facilitating understanding of this utility model and is not intended to limit this utility model. Any person skilled in the art to which this utility model pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this utility model, but the patent protection scope of this utility model shall still be determined by the scope defined in the appended claims.
