Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of low-voltage electrical apparatus, and particularly relates to a cost control controller and electronic equipment. BACKGROUND
[0002] With the state vigorously advocating green products, people's attention to the power consumption problem of products is increasing, which makes low-power design a mainstream trend in product design.
[0003] Especially in the application of the external circuit breaker of the electric energy meter, since it is installed in the rear stage of the electric energy meter, the power consumption requirement of the circuit breaker is very high. Usually, the phase leakage current of the circuit breaker in the steady state is required to be less than 0.2 mA.
[0004] However, in order to meet the above requirements, most designs put forward higher standards for each module, especially the low-power requirement of the power supply, which directly leads to the relative increase of the overall cost. CONTENT OF THE UTILITY MODEL
[0005] The present application provides a cost control controller and electronic equipment, which can further reduce the power consumption of the cost control controller in the standby state, thereby reducing the overall energy consumption and prolonging the service life without increasing the cost.
[0006] In a first aspect, the present application provides a cost control controller, which comprises a power module and an execution module.
[0007] The power module is connected with an alternating current power supply, and the power module can rectify, filter and transform the alternating current signal generated by the alternating current power supply. The execution module is electrically connected with the power module.
[0008] The power module comprises a controllable control chip, the control chip has at least one control pin, the signal received by the control pin is a low-level signal, the control chip normally operates, and the signal received by the control pin is a high-level signal, and the control chip stops operating.
[0009] The power module adopts a controllable power supply scheme, and by controlling the shutdown of the control chip, the power module does not work in most time, thereby greatly reducing the power consumption problem caused by the control chip itself.
[0010] The execution module is responsible for executing corresponding operations according to the instructions of the fee control controller, such as controlling the on-off state of household appliances and the on-off state of factory electronic equipment. In addition, the fee control controller of the present application can also have an intelligent control function, which can automatically adjust the output of the power module according to the preset conditions to achieve the purpose of energy saving. For example, when it is detected that the corresponding control chip or main control module is in standby state, the fee control controller can automatically reduce the output power of the power module, thereby reducing the waste of electric energy.
[0011] Specifically, the power module in the fee control controller adopts a controllable control chip, which not only improves the energy efficiency of the fee control controller, but also enhances its safety.
[0012] The control chip is the core of the power module and is responsible for the operation control of the entire power module. The control chip has multiple pins, at least one of which is a control pin. The control pin is responsible for receiving external control signals. When the control pin receives a low-level signal, the control chip will execute its functions normally according to this signal instruction, maintaining the normal operating state of the power module. On the contrary, when the control pin receives a high-level signal, the control chip will recognize this signal as a stop running instruction and stop its operation immediately, thereby achieving the shutdown control of the power module. This design allows the operating state of the power module to be accurately controlled by external signals, improving the flexibility and safety of the power module.
[0013] In some examples, the alternating current signal is converted into a preset voltage after rectification, filtering and voltage transformation, and the preset voltage is connected to the execution module as the driving voltage of the execution module. The power module includes a transformer for changing the voltage.
[0014] By accurately controlling the turns ratio of the transformer, the alternating current signal can be stably converted into the required preset voltage. In addition, the transformer also has multiple protection mechanisms such as overcurrent and overvoltage to ensure that the power supply can be quickly cut off in abnormal conditions to protect the execution module from damage. This design not only improves the reliability and stability of the fee control controller, but also further enhances its ability to adapt to complex environments.
[0015] In some examples, the fee control controller further includes a main control module connected to the power module. The power module further includes a voltage stabilizer, and the preset voltage is converted into a control voltage after being stepped down by the voltage stabilizer, and the control voltage is used as the power voltage of the main control module.
[0016] The main control module is the core component of the fee control controller and is responsible for receiving and processing signals from the outside and controlling the power module and the execution module according to the preset logic algorithm. Through the connection with the power module, the main control module can obtain real-time power state information and adjust the control strategy according to these information to ensure the stable operation of the fee control controller.
[0017] The voltage stabilizer can further enhance the voltage adaptability of the fee control controller. In the case of a large preset voltage fluctuation, the voltage stabilizer can effectively stabilize it within a certain range, thereby providing a stable power supply voltage for the main control module. This not only improves the working stability of the main control module, but also prolongs its service life.
[0018] In some examples, the preset voltage is 12V voltage and the control voltage is 3.3V voltage.
[0019] Under such voltage configuration, the main control module can efficiently operate while maintaining low power consumption characteristics. The 12V voltage as the main power supply provides sufficient energy for the entire fee control controller, while the 3.3V voltage as the control voltage is used to drive the logic circuit inside the main control module. This voltage configuration not only optimizes energy utilization, but also ensures the stable operation of the main control module in complex environments. In addition, through fine voltage management, the overall power consumption of the fee control controller is further reduced, making it more in line with the development trend of low-power electronic devices.
[0020] In some examples, the fee control controller further comprises a voltage detection module connected with the alternating current power supply. The alternating current signal is converted into a first voltage after rectification, voltage division and voltage stabilization by the voltage detection module. The first voltage drives the voltage detection module to be in a conducting state after passing through at least one resistor, and forms a low-level signal at the corresponding position.
[0021] The voltage detection module does not receive the alternating current signal, and the voltage detection module is in a cut-off state and forms a high-level signal at the corresponding position. Alternatively, the alternating current signal is converted into a second voltage after rectification and voltage division by the voltage detection module. The second voltage drives the voltage detection module to be in a cut-off state after passing through at least one resistor, and forms a high-level signal at the corresponding position.
[0022] The low-level signal and the high-level signal are transmitted directly or indirectly to the control pin.
[0023] After the voltage detection module is connected with the alternating current power supply, the alternating current signal will first pass through the voltage detection module for a series of processing, including rectification, voltage division and voltage stabilization, and finally be converted into a stable direct current voltage, i.e. the first voltage. The first voltage will then pass through at least one resistor, and the resistor will reduce the voltage value in order to drive the voltage detection module to enter the conducting state. When the voltage detection module is in the conducting state, a low-level signal will be formed at the corresponding position of the circuit. When the control pin receives the low-level signal as described above, the control chip will normally execute its functions according to this signal instruction, maintaining the normal operating state of the power supply module.
[0024] When the voltage detection module does not receive an alternating current signal, it will be in an off state, at which time a high level signal will be formed at the corresponding position of the circuit. In addition, after the alternating current signal passes through the rectification and voltage division of the voltage detection module, it will be converted into another direct current voltage, i.e. a second voltage. This second voltage will also pass through at least one resistor, and the role of the resistor is still to reduce the voltage value to ensure that the voltage detection module remains in an off state. In the off state, a high level signal will be formed at the corresponding position of the circuit.
[0025] When the control pin receives a high level signal, the control chip will recognize this signal as an instruction to stop running, and will stop running immediately, thereby achieving the control of turning off the power module. The high level signal can be used as a digital signal basis for the single-chip microcomputer in the fee control controller to judge whether there is an alternating current power supply.
[0026] In some examples, the voltage detection module includes a rectifier diode, at least two resistors, at least two voltage stabilizing tubes, a capacitor and a triode connected to each other. The voltage stabilizing tube close to the rectifier diode is a first voltage stabilizing tube, the constant voltage of the first voltage stabilizing tube is a threshold voltage, and the threshold voltage is 120V. When the alternating current voltage is greater than 120V, it is a usable power supply.
[0027] When the alternating current voltage is lower than 120V, the voltage detection module determines that the voltage does not meet the working requirements of the fee control controller, and thus does not supply power to the subsequent circuit, effectively preventing equipment abnormalities or damage caused by low voltage. In addition, the resistors, capacitors and other elements in the voltage detection module are carefully selected and arranged, further optimizing the anti-interference performance and stability of the circuit, ensuring that the voltage detection and judgment functions can be accurately and reliably completed under various voltage fluctuations. This design not only improves the overall performance of the fee control controller, but also provides users with a more secure and stable power experience.
[0028] In some examples, the preset voltage is transmitted to at least two resistors, and the preset voltage is divided by voltage division. One of the resistors is connected in parallel with at least one resistor and at least one capacitor to form a filter network. The preset voltage after voltage division can be converted into a stable voltage analog signal through the filter network, and the voltage analog signal can be directly or indirectly transmitted to the single-chip microcomputer of the fee control controller.
[0029] The design of the filter network effectively eliminates high-frequency noise and interference in the voltage signal, improving the purity and stability of the voltage analog signal. After receiving the stable voltage analog signal, the single-chip microcomputer can more accurately judge the current voltage state, thereby achieving precise control of the fee control controller. In addition, by adjusting the parameters of the resistors and capacitors, the filtering effect can be further optimized to adapt to the needs of different application scenarios. This design not only improves the performance of the fee control controller, but also enhances its adaptability to complex voltage environments, providing users with a more reliable and stable power management solution.
[0030] In some examples, the execution module includes a drive core and a DC motor, the drive core is connected with the control chip, when the signal received by the control pin is a low-level signal, at least two pins in the drive core are low-level, and the DC motor stops running, and the drive core is in a sleep mode.
[0031] When the signal received by the control pin is a high-level signal, the corresponding pin in the drive core is activated, and the DC motor starts running. This design enables the fee control controller to accurately control the start and stop of the DC motor according to the instructions of the control chip, thereby realizing precise management of the power load. In addition, through the low-level control of the drive core, the DC motor can quickly enter the sleep mode when it does not need to run, effectively reducing energy consumption and prolonging the service life of the fee control controller. This intelligent power management method not only improves the performance of the fee control controller, but also brings users a more energy-saving and environmentally friendly power usage experience.
[0032] In some examples, the fee control controller further includes a main control module and a display module, the main control module is a single-chip microcomputer, and the display module includes a dual-color indicator light arranged on the single-chip microcomputer, different indication states of the dual-color indicator light correspond to different working states of the fee control controller.
[0033] When the fee control controller is in a normal working state, the dual-color indicator light displays green, and when the fee control controller fails or needs maintenance, the dual-color indicator light turns red. This intuitive display method facilitates users to quickly understand the running state of the fee control controller. The main control module, as the core of the fee control controller, is responsible for receiving and processing signals from the outside and controlling the work of each module according to the preset program logic. By using a single-chip microcomputer as the main control module, not only the intelligent degree of the fee control controller is improved, but also the running of the fee control controller is more stable and reliable. In addition, the design of the display module also fully considers the user experience, so that users can easily master the state of the fee control controller, and thus take corresponding measures in time.
[0034] In a second aspect, the application provides an electronic device including the fee control controller and the functional components as described above, and the functional components are electrically connected with the fee control controller.
[0035] The electronic device of the application integrates the fee control controller and various functional components as described above. These functional components are electrically connected with the fee control controller and cooperate to realize intelligent control and energy-saving management of the electronic device. For example, in a smart home system, the electronic device can serve as a central controller to intelligently schedule and manage the power consumption of various electrical devices in the home through the fee control controller, thereby achieving the purpose of energy saving and emission reduction.

[0045] In order to make the technical solutions in the application or the prior art clearer, the accompanying drawings needed to be used in the examples or the prior art description will be briefly introduced as follows. Obviously, the accompanying drawings in the following description are only some examples of the application, and other accompanying drawings can be obtained by those skilled in the art without any creative effort on the basis of these accompanying drawings.
[0046] In order to solve the above technical problems, please refer to Figures 1-6 The first aspect of the application proposes a fee control controller, which can further reduce the power consumption of the fee control controller in the standby state, so that the overall energy consumption can be reduced and the service life can be prolonged without increasing the cost.
[0047] As Figure 1As shown, the fee control controller involved in the present application has multiple key components, including but not limited to power module 100, execution module 200, main control module 300, voltage detection module 400, display module 500, and fee control and feedback module 600.
[0048] Among these modules, the power module 100 is responsible for converting alternating current signals into stable direct current 12V and 3.3V voltages to provide necessary power support for the entire system. The execution module 200 is mainly composed of motor drives, responsible for converting the instructions of the main control module 300 into actual physical actions, such as driving a 12V DC motor for precise control. The main control module 300 serves as the central nervous system of the entire system, intelligently determining whether to drive the execution mechanism in the execution module 200 to perform corresponding actions according to the current working mode and signals from the fee control and voltage detection module 400. The voltage detection module 400 is responsible for monitoring the presence of the input alternating current signal and the real-time voltage value of the DC 12V voltage, ensuring that the system operates within a safe voltage range. The display module 500 usually includes a dual-color LED indicator light that can display different colors according to the current state of the system, providing intuitive status indication for the operator. Finally, the fee control and feedback module 600 not only includes the processing of alternating 220V level signals, but also includes feedback signals on whether the output side of the product has successfully closed after closing, ensuring the reliability and safety of the entire system.
[0049] The fee control and feedback module 600 includes alternating 220V level signals, and the feedback is a reaction to whether the output side of the product has successfully closed after closing. The fee control and feedback module 600 can receive fee control signals from the power grid and control the execution module 200 to perform corresponding actions such as closing or opening according to the signal content. At the same time, the fee control and feedback module 600 can also monitor the state of the output side of the product in real time to ensure the successful execution of the fee control operation. Once it is detected that the fee control operation has failed to be successfully executed, such as the output side has not successfully closed after closing, the system will immediately issue an alarm and take appropriate remedial measures to ensure the safe and stable operation of the power grid. This design not only improves the accuracy of fee control operation, but also provides users with a more reliable and safe electricity experience.
[0050] Referring to Figure 1 and Figure 2 In some examples, the present application provides a fee control controller, which includes a power module 100 and an execution module 200.
[0051] The power module 100 is connected to an alternating current power source, and the power module 100 can rectify, filter and transform the alternating current signals generated by the alternating current power source. The execution module 200 is electrically connected to the power module 100.
[0052] The power module 100 comprises a controllable control chip, and the control chip has at least one control pin.
[0053] The power module 100 adopts a controllable power supply scheme, and by controlling the shutdown of the control chip, the power module 100 is not working most of the time, thereby greatly reducing the power consumption problem caused by the control chip itself.
[0054] The execution module 200 is responsible for executing corresponding operations according to the instructions of the fee control controller, such as controlling the on-off state of household appliances and the on-off state of factory electronic equipment. In addition, the fee control controller of the present application can also have an intelligent control function, which can automatically adjust the output of the power module 100 according to the preset conditions to achieve the purpose of energy saving. For example, when it is detected that the corresponding control chip or master control module is in standby state, the fee control controller can automatically reduce the output power of the power module 100, thereby reducing the waste of electric energy.
[0055] Specifically, the power module 100 in the fee control controller adopts a controllable control chip, which not only improves the energy efficiency of the fee control controller, but also enhances its safety.
[0056] The control chip is the core of the power module 100 and is responsible for the operation control of the entire power module 100. The control chip is designed with multiple pins, at least one of which is a control pin. The control pin is responsible for receiving external control signals. When the signal received by the control pin is a low-level signal, the control chip will normally execute its functions according to this signal instruction, maintaining the normal operation state of the power module 100. On the contrary, when the signal received by the control pin is a high-level signal, the control chip will recognize this signal as a stop running instruction, and then stop its running, thereby realizing the shutdown control of the power module 100. This design makes the running state of the power module 100 can be accurately controlled by external signals, improving the flexibility and safety of the power module 100.
[0057] And when the control chip receives a high-level signal, it can stop running immediately, thereby effectively avoiding the safety hazards such as circuit short circuit or overload caused by power failure and the like. At the same time, this controllable design also makes the fee control controller can further reduce the power consumption in standby state, prolong the service life.
[0058] In summary, the power control controller provided by the application realizes intelligent control of load devices such as household appliances by adopting the combination design of the power module 100 and the execution module 200 and the technical means of the controllable control chip, and achieves the purposes of energy saving, safety, and high efficiency.
[0059] Specifically, the control chip can be an alternating current-direct current (AC-DC) chip. The AC-DC chip can convert the input alternating voltage into stable direct current voltage to provide reliable power supply for the power control controller. By adopting the AC-DC chip as the control chip, the circuit design is simplified, the cost is reduced, and the overall efficiency and stability of the power control controller are improved. In addition, the AC-DC chip has a wide input voltage range, high efficiency, low standby power consumption, and multiple protection functions such as overvoltage and overcurrent, ensuring the safe and stable operation of the power control controller under various complex working conditions. By integrating the AC-DC chip, the power control controller of the application exhibits excellent performance and reliability in power management, providing users with a more convenient and efficient power use experience. The controllable control chip can have lower energy consumption.
[0060] The power module 100 of the application adopts a controllable power supply scheme, which controls the shutdown of the AC-DC chip to realize that the power module 100 does not work most of the time, thereby greatly reducing the power consumption problem caused by the AC-DC module itself. Such a setting can correspond to the main control module 300 adopting a low-power MCU scheme, i.e., a microcontroller unit, to further reduce the power consumption of the entire system. The voltage detection module 400 is used to detect the presence or absence of the input alternating signal and the voltage value of the DC 12V voltage, to ensure that the system works within the appropriate voltage range. The execution module 200 is mainly used for motor driving and 12V direct current motor to execute power control and other operations.
[0061] In some examples, the alternating signal is converted into a preset voltage after rectification, filtering, and voltage transformation, and the preset voltage is connected to the execution module 200 and used as the driving voltage of the execution module. The power module 100 includes a transformer for changing the voltage.
[0062] By accurately controlling the turns ratio of the transformer, the alternating signal can be stably converted into the required preset voltage. In addition, the transformer also has multiple protection mechanisms such as overcurrent and overvoltage, which can quickly cut off the power supply in abnormal conditions to protect the execution module 200 from damage. Such a design not only improves the reliability and stability of the power control controller, but also further enhances its ability to adapt to complex environments.
[0063] Reference Figure 2, which shows the detailed circuit structure of the power module 100 involved in this patent application. Based on the description of the drawings, the AC signal first undergoes a series of processing procedures, including rectification and filtering, and then is converted into stable DC 12V voltage through the action of components such as ACDC chip and transformer. The DC 12V voltage is used to drive the DC motor, i.e. as the power source of the actuator.
[0064] In addition, the 12V voltage will also be further processed by the voltage stabilizer to obtain a stable voltage of 3.3V. This 3.3V voltage can be used as the power supply of the main controller, ensuring the stable operation of the main controller.
[0065] In the present power module 100, the ACDC chip U1 has an important shut-off function. Its 2nd pin is a control pin, when the control pin is at low level, the chip will normally operate; when the control pin is at high level, the chip will be turned off and stop working. In order to realize the control of the ACDC chip U1, the entire module can be connected to the single-chip microcomputer through the resistor R24 in the power module 100, so that the single-chip microcomputer can control the opening and closing of the ACDC chip U1.
[0066] In some examples, the fee control controller further includes a main control module 300 connected with the power module 100, and the power module 100 further includes a voltage stabilizer, the preset voltage is converted into a control voltage after being stepped down by the voltage stabilizer, and the control voltage is used as the power voltage of the main control module 300.
[0067] The main control module 300 is the core component of the fee control controller, responsible for receiving and processing signals from the outside, and controlling the power module 100 and the execution module 200 according to the preset logic algorithm. Through the connection with the power module 100, the main control module 300 can obtain real-time power state information, and adjust the control strategy according to these information, to ensure the stable operation of the fee control controller.
[0068] The voltage stabilizer can further enhance the voltage adaptability of the fee control controller. In the case of large fluctuations in the preset voltage, the voltage stabilizer can effectively stabilize it within a certain range, thereby providing stable power voltage for the main control module 300. This not only improves the working stability of the main control module 300, but also prolongs its service life.
[0069] In addition, the main control module 300 also has various protection functions, such as overcurrent protection, overvoltage protection, short circuit protection, etc. In the event of abnormal conditions, the main control module 300 can quickly respond and take appropriate protective measures to prevent the fee control controller from being damaged. The implementation of these protection functions further improves the reliability and safety of the fee control controller.
[0070] The above-mentioned main control module 300 adopts a low-power MCU scheme. The selection of the MCU scheme is based on its ultra-low power consumption characteristics, especially in standby mode, its power consumption is extremely low, which can greatly prolong the standby time of the product. In addition, the MCU also has high-performance processing capability, which can quickly respond to various instructions of the system, ensuring the real-time and stability of the system. By adopting such a MCU scheme, the main control module 300 of the present application can maximize the reduction of power consumption while ensuring performance, thereby meeting the requirements of low-power design. In actual application, the MCU scheme has been widely verified and applied, and its stability and reliability have been recognized by users. Therefore, the use of such a MCU scheme can better realize the low-power fee control controller.
[0071] In some examples, the preset voltage is a 12V voltage, and the control voltage is a 3.3V voltage.
[0072] Under such a voltage configuration, the main control module 300 can efficiently operate while maintaining low power consumption characteristics. The 12V voltage as the main power source provides sufficient energy for the entire fee control controller, and the 3.3V voltage as the control voltage is used to drive the logic circuit inside the main control module 300. Such a voltage configuration not only optimizes energy utilization, but also ensures the stable operation of the main control module 300 in complex environments. In addition, through fine voltage management, the overall power consumption of the fee control controller is further reduced, making it more in line with the development trend of low-power electronic devices.
[0073] In some examples, the fee control controller further comprises a voltage detection module 400 connected with the alternating current power supply, and the alternating current signal is converted into a first voltage after rectification, voltage division and voltage stabilization by the voltage detection module 400. The first voltage drives the voltage detection module 400 to be in a conducting state after passing through at least one resistor, and forms a low-level signal at the corresponding position.
[0074] The voltage detection module 400 does not receive the alternating current signal, and the voltage detection module 400 is in a cut-off state and forms a high-level signal at the corresponding position. Alternatively, the alternating current signal is converted into a second voltage after rectification and voltage division by the voltage detection module 400. The second voltage drives the voltage detection module 400 to be in a cut-off state after passing through at least one resistor, and forms a high-level signal at the corresponding position, which can be used as a digital basis for whether the single-chip microcomputer in the fee control controller exists alternating current power supply.
[0075] The low-level signal and the high-level signal are directly or indirectly transmitted to the control pin.
[0076] The voltage detection module 400 is connected to the AC power supply, the AC signal will first pass through the voltage detection module 400 for a series of processing, including rectification, voltage division and voltage stabilization, and finally converted into a stable DC voltage, that is, the first voltage. The first voltage will then pass through at least one resistor, the role of the resistor is to reduce the voltage value, in order to drive the voltage detection module 400 into the conduction state. When the voltage detection module 400 is in the conduction state, a low-level signal will be formed at the corresponding position of the circuit. When the control pin receives the above-mentioned low-level signal, the control chip will execute its function according to the signal instruction, and maintain the normal operation state of the power supply module 100.
[0077] When the voltage detection module 400 does not receive the AC signal, it will be in the off state, at which time a high-level signal will be formed at the corresponding position of the circuit. In addition, after the AC signal passes through the rectification and voltage division of the voltage detection module 400, it will be converted into another DC voltage, that is, the second voltage. This second voltage will also pass through at least one resistor, and the role of the resistor is still to reduce the voltage value to ensure that the voltage detection module 400 remains in the off state. In the off state, a high-level signal will be formed at the corresponding position of the circuit.
[0078] When the control pin receives a high-level signal, the control chip will recognize this signal as a stop running instruction, and then stop its running, thereby realizing the shutdown control of the power supply module 100. The high-level signal can be used as a digital signal basis for the single-chip microcomputer in the fee control controller to judge whether there is an AC power supply.
[0079] These low-level signals and high-level signals can be directly or indirectly transmitted to the control pin, thereby realizing the control and signal processing of the fee control controller.
[0080] The control chip on the fee control controller can receive low-level signals and high-level signals from the voltage detection module 400. The control chip has a built-in logic judgment circuit that can identify whether the fee control controller is connected to an effective AC power supply. When a low-level signal is identified, it indicates that the AC power supply is normally powered, and at this time the control chip will send a working instruction to the core single-chip microcomputer of the fee control controller. Conversely, if a high-level signal is identified, it indicates that the AC power supply is disconnected or abnormal, and the control chip will immediately send a power-off protection or low-power standby mode instruction to the single-chip microcomputer.
[0081] In addition, the control chip can also set up a fault self-diagnosis structure as needed, so as to be able to monitor the working state of the voltage detection module 400 in real time. Once it finds that the voltage detection module 400 is faulty, such as abnormal or unstable output signal, the control chip will immediately trigger the alarm mechanism and try to start the backup power supply or execute the safety shutdown program, to ensure the stable operation of the fee control controller and the connected devices.
[0082] Referring to Figure 3 , the voltage detection module 400 is shown, in which, in the process of the AC signal A-phase voltage, first rectification operation is performed by diode VD9, and then a series of resistors and voltage stabilizing tubes, including resistors R14 and R16 and voltage stabilizing tubes VD10 and VD11, are used to obtain a stable voltage value VA. The obtained VA voltage is further driven by resistors R20 and R21, and is finally used to drive triode VT3.
[0083] The capacitor C19 in the drawing plays a filtering role. Specifically, the main function of the capacitor C19 in the circuit is to convert the pulsating direct current after the rectifier treatment into a more smooth and stable direct current signal. In this process, VD11 plays a voltage detection role, and VD11 is a voltage stabilizing diode with a voltage stabilizing value of 120V. When the voltage of the AC power supply exceeds 120V, we can consider that the power supply is available, because it indicates that the voltage of the power supply is sufficient.
[0084] Specifically, when the AC power supply is input into the circuit, the triode VT3 will be in a conducting state, and at this time the level on the AC_ON signal line will become low. Conversely, if the AC power supply disappears, i.e. there is no input voltage, the triode VT3 will be cut off, and the level on the AC_ON signal line will become high. This digital signal is then transmitted to the single-chip microcomputer, which judges the state of the power supply through this digital quantity.
[0085] In another part of the circuit, resistors R10 and R51 jointly act on the voltage of 12V, and through their voltage division, a specific voltage value can be obtained. This voltage value is processed by a filter network composed of resistor R15 and capacitor C13 to form a stable voltage signal POWER_ADC. This analog signal is then transmitted to the single-chip microcomputer, which further judges the stability and quality of the power supply through this analog quantity.
[0086] Referring to Figure 3 , the voltage detection module 400 includes a rectifier diode, at least two resistors, at least two voltage stabilizing tubes, a capacitor, and a triode, the rectifier diode is used to rectify an AC signal, the at least two resistors are used to divide the voltage of the rectified AC signal, the voltage stabilizing tubes are used to stabilize the received voltage signal, the capacitor is connected in parallel with one of the voltage stabilizing tubes and filters the received voltage signal, and the triode is turned on and off according to the voltage detection module 400.
[0087] The rectifier diode converts the alternating signal into a direct current signal, providing a stable voltage basis for the subsequent circuit. The voltage dividing network composed of at least two resistors ensures that alternating signals of different voltage levels can be appropriately reduced to a level suitable for subsequent circuit processing. The voltage stabilizing tube further stabilizes these voltage signals after voltage division, preventing voltage fluctuations from adversely affecting the cost control controller.
[0088] The parallel combination of capacitors and voltage stabilizing tubes not only helps to smooth voltage fluctuations and reduce noise interference, but also enhances the anti-interference ability of the circuit. The triode, as the core switching element of the voltage detection module 400, its on-off state directly reflects the working state of the voltage detection module 400. When the input voltage reaches the preset threshold, the triode is turned on or off, thereby sending the corresponding level signal to the control chip, triggering subsequent logic judgment and action instructions.
[0089] This design of voltage detection module 400 not only has simple structure and low cost, but also has high reliability and stability, which can meet the working requirements of the cost control controller in various complex environments.
[0090] In some examples, the voltage detection module 400 includes a rectifier diode, at least two resistors, at least two voltage stabilizing tubes, a capacitor, and a triode connected to each other. The voltage stabilizing tube close to the rectifier diode is the first voltage stabilizing tube, the constant voltage of the first voltage stabilizing tube is the threshold voltage, and the threshold voltage is 120V. When the alternating voltage is greater than 120V, it is a usable power supply.
[0091] When the alternating voltage is lower than 120V, the voltage detection module 400 determines that the voltage does not meet the working requirements of the cost control controller, and thus does not supply power to the subsequent circuit, effectively preventing equipment abnormalities or damage caused by low voltage. In addition, the resistors, capacitors and other elements in the voltage detection module 400 are carefully selected and arranged, further optimizing the anti-interference performance and stability of the circuit, ensuring that the voltage detection and judgment functions can be accurately and reliably completed under various voltage fluctuations. This design not only improves the overall performance of the cost control controller, but also provides users with a safer and more stable power experience.
[0092] In some examples, the preset voltage is transmitted to at least two resistors, and the preset voltage is divided by the at least two resistors. One of the resistors is connected in parallel with at least one resistor and at least one capacitor to form a filter network. The divided preset voltage can be converted into a stable voltage analog signal through the filter network. The voltage analog signal can be directly or indirectly transmitted to the single-chip microcomputer of the cost control controller.
[0093] The design of the filter network effectively eliminates high-frequency noise and interference in the voltage signal, improving the purity and stability of the voltage analog signal. After receiving the stable voltage analog signal, the single-chip microcomputer can more accurately determine the current voltage state, thereby achieving precise control of the feed control controller. In addition, by adjusting the parameters of resistance and capacitance, the filtering effect can be further optimized to adapt to the needs of different application scenarios. This design not only improves the performance of the feed control controller, but also enhances its adaptability to complex voltage environments, providing users with a more reliable and stable power management solution.
[0094] In some examples, the execution module 200 includes a drive core and a DC motor, the drive core is connected with the control chip, when the signal received by the control pin is a low-level signal, at least two pins in the drive core are low-level, and the DC motor stops running, and the drive core is in sleep mode.
[0095] When the signal received by the control pin is a high-level signal, the corresponding pin in the drive core will be activated, and the DC motor will start running. This design enables the feed control controller to accurately control the start and stop of the DC motor according to the instructions of the control chip, thereby achieving precise management of the power load. In addition, through the low-level control of the drive core, the DC motor can quickly enter sleep mode when it does not need to run, effectively reducing energy consumption and prolonging the service life of the feed control controller. This intelligent power management method not only improves the performance of the feed control controller, but also provides users with a more energy-saving and environmentally friendly power usage experience.
[0096] Referring to Figure 4 , the detailed composition of the execution module 200 is shown, which includes the motor drive core U4 and the DC motor J1.
[0097] When the input ends IN1 and IN2 are both in a low-level state, i.e., no driving signal is provided to the motor, the motor drive core U4 will automatically enter a super-low-power sleep mode. In this mode, the current consumption of the chip will be greatly reduced, with a specific value less than 100 nanoamperes (nA), thereby effectively saving energy.
[0098] When IN1 or IN2 receives a high-level signal, the motor drive core U4 is activated, and the DC motor J1 starts running. This design not only achieves precise control of the DC motor, but also significantly reduces energy consumption in the non-working state. Figure 4 The execution module 200 in demonstrates the efficient cooperation between the motor drive core U4 and the DC motor J1, providing a stable and energy-saving power drive solution for the feed control controller. Through the optimization of circuit design, the overall performance of the feed control controller and the user's experience are further improved.
[0099] Referring to Figure 5In some examples, the fee control controller further comprises a master module 300 and a display module 500. The master module 300 is a single-chip microcomputer, and the display module 500 comprises a dual-color indicator light arranged on the single-chip microcomputer. Different indicator states of the dual-color indicator light correspond to different working states of the fee control controller. The dual-color indicator light can be composed of two integrated light-emitting diodes. The two light-emitting diodes can be connected to the LED_R interface and the LED_R interface on the level machine, respectively, and can be independently controlled.
[0100] When the fee control controller is in a normal working state, the dual-color indicator light displays green. When the fee control controller fails or needs maintenance, the dual-color indicator light turns red. This intuitive display method allows users to quickly understand the running state of the fee control controller. The master module 300, as the core of the fee control controller, is responsible for receiving and processing signals from the outside and controlling the work of each module according to the preset program logic. By using a single-chip microcomputer as the master module 300, the intelligence level of the fee control controller is improved, and the operation of the fee control controller is more stable and reliable. In addition, the design of the display module 500 also fully considers the user experience, so that users can easily master the state of the fee control controller and take corresponding measures in a timely manner.
[0101] The display module 500 can also be provided with a display screen, and the dual-color indicator light can be replaced by other types of indicator lights, such as two independent variable-color indicator lights, three-color indicator lights, digital displays, liquid crystal displays, etc.
[0102] These diversified display methods not only provide more abundant state information, but also meet the individual needs of different users. For example, the digital display can accurately display various parameters of the fee control controller, such as the remaining power and the power factor, so that users have a more comprehensive understanding of the running state of the fee control controller. The liquid crystal display can display information in a graphical manner, making the state display more intuitive and easy to understand. In addition, the two independent variable-color indicator lights or the three-color indicator lights can represent different states of the fee control controller, such as normal working, pre-warning, and failure, through different color combinations, further improving the user experience. These designs make the fee control controller more intelligent and user-friendly, greatly facilitating the use of users.
[0103] Reference Figure 4 and Figure 5 Some circuits are provided with a structure of two capacitors in parallel. The parallel connection of capacitors mainly has the following effects:
[0104] One, increase the total equivalent capacitance. When capacitors are connected in parallel, their total equivalent capacitance is equal to the sum of their individual capacitances. This means that by connecting in parallel, the amount of charge storage in the circuit can be significantly increased, thus meeting the needs of some circuits that require large capacitance capacity, such as filter circuits and power supply circuits of electronic devices.
[0105] Two, improve the stability of the circuit. In power supply circuits, parallel connection of capacitors helps to reduce the internal resistance of the power supply, thus providing more stable voltage output. In filter circuits, parallel connection of capacitors can smooth the output waveform of the power supply, further reducing noise and interference, and improving the overall stability of the circuit.
[0106] Three, reduce the voltage of the equivalent capacitor. When capacitors are connected in parallel, the voltage will be distributed among the individual capacitors, thus reducing the voltage bearing value of each capacitor. This helps to avoid capacitor breakdown or damage caused by excessive voltage, improving the safety of the circuit.
[0107] Four, improve the power factor. In AC circuits, parallel connection of capacitors can compensate for the phase difference of current caused by inductive load, thus improving the power factor of the circuit. This not only helps to reduce line loss, but also improves power quality and overall efficiency of the circuit.
[0108] Five, adjust the frequency response of the circuit. Parallel connection of capacitors can also change the resonant frequency of the circuit, thus adjusting the frequency response of the circuit. This is particularly useful in the design of amplifiers and filter circuits, and can meet the needs of different application scenarios for frequency characteristics.
[0109] Six, adapt to different types of signals. In circuits that need to process high and low frequency signals at the same time, parallel connection of different types of capacitors can take advantage of their respective advantages. For example, small capacity capacitors are easy to pass high frequency signals, while large capacity capacitors are easy to pass low frequency signals. Therefore, by reasonably matching different types of capacitors in parallel, we can better adapt to the needs of complex signal environments.
[0110] In summary, parallel connection of two capacitors in a circuit plays multiple roles, including increasing capacitance, improving circuit stability, reducing voltage, improving power factor, adjusting frequency response, and adapting to different types of signals. These effects collectively improve the performance and reliability of the circuit.
[0111] Reference Figure 6 , shows the specific flowchart of reducing power consumption in the present application, which details the steps and logic of the entire power consumption reduction process.
[0112] At the output end of the ACDC module, two large capacitors C6 and C7 are placed (as shown in Figure 1As shown in the figure, these capacitors play an important role in the circuit. However, the AC-DC chip itself also consumes a certain amount of power, which leads to very low overall conversion efficiency in low load conditions.
[0113] In view of this, a single-chip microcomputer with ultra-low power consumption is used to solve this problem. In normal operation mode, the single-chip microcomputer mainly works in low-power mode, so that when the motor does not need to be driven, the system can rely on the energy stored in capacitors C6 and C7 to maintain normal operation.
[0114] In addition, when it is detected that the input end of the product has no voltage, the product will stop performing any other operations until the power input end is detected to have voltage again.
[0115] In order to ensure that the main controller can continue to run, a detection mechanism is designed to monitor whether the 12V voltage is lower than 6V. Once it is detected that the voltage is lower than 6V, the system will immediately start the ACDC chip to charge capacitors C6 and C7, ensuring that the main controller is always in operation. In this design, the energy stored in capacitors C6 and C7 is sufficient to ensure that the product can run for more than 60 seconds without external power supply.
[0116] When it is detected that the need for the fee control signal is inconsistent with the current state of the product, the system will drive the motor to meet the state indicated by the fee control signal. In the process of driving the motor, the ACDC chip will remain open to ensure that sufficient energy is provided to drive the motor.
[0117] In this way, the main power consumption of the product in normal operation mainly comes from the power consumption of the single-chip microcomputer. The overall running current can be controlled below 0.2mA, thereby meeting the design requirements of low power consumption of the product.
[0118] In a second aspect, the application provides an electronic device comprising the fee control controller and the functional components as described above, and the functional components are electrically connected to the fee control controller.
[0119] The electronic device of the present application integrates the above-mentioned fee control controller and various functional components. These functional components are electrically connected to the fee control controller and cooperate to realize intelligent control and energy management of the electronic device. For example, in a smart home system, the electronic device can serve as a central controller to intelligently schedule and manage the power consumption of various electrical appliances in the home through the fee control controller, thereby achieving the purpose of energy saving and emission reduction.
[0120] In addition, the electronic device also has high scalability and flexibility. Users can freely select and combine different functional components according to actual needs to meet individualized use requirements. This design not only improves the practicality of the electronic device, but also brings users a more convenient and intelligent life experience.
[0121] It is worth mentioning that the electronic device provided by the present application performs well in energy saving. Through the intelligent control function of the fee control controller, the electronic device can monitor and analyze the power consumption of each load device in real time, and automatically adjust the output of the power module 100 according to the preset strategy to achieve the best energy saving effect. At the same time, the electronic device also has multiple safety protection mechanisms such as overvoltage protection and overcurrent protection, to ensure that the normal operation and use safety of the device are not affected while saving energy.
[0122] In summary, the electronic device provided by the present application realizes intelligent control and energy saving management of load devices by integrating a fee control controller and multiple functional components. The electronic device not only has high scalability and flexibility, but also performs well in energy saving, bringing users a more convenient, intelligent and environmentally friendly life experience.
