Description

Technical Field

[0001] This application relates to the field of smart homes, and in particular to a smart dual-control switch and load circuit. Background Technology

[0002] A two-way switch is a device that allows users to control loads from different locations. A two-way switch includes an input terminal and two output terminals. The input terminal can be connected to either of the two output terminals. The switching state of the two-way switch can be changed by changing the output terminal connected to the input terminal.

[0003] A smart double-pole switch is a double-pole switch that can intelligently control the switch state. In addition to the input terminal and two output terminals, the smart double-pole switch also includes a load resistor and a control module. The load resistor is connected in series with the load connected to the smart double-pole switch. The control module can determine the state of the load based on the state of the load resistor, change the output terminal that is connected to the input terminal, control the switching state of the smart double-pole switch, and thus control the switching state of the load.

[0004] Although intelligent double-control switches with built-in load resistors can achieve intelligent control of the switch status, they cannot accurately monitor the circuit data of the loads connected to the intelligent double-control switch, resulting in low energy-saving efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide an intelligent dual-control switch that can accurately monitor the circuit data of the load while achieving intelligent control of the switch status, thereby improving energy efficiency.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] In a first aspect, this application provides an intelligent dual-control switch, which includes an input terminal, two output terminals, a switch module, a metering module, and a control module. One end of the switch module is connected to the input terminal, and the other end of the switch module is connected to either of the two output terminals. The metering module includes two sampling terminals, each of which is connected to an output terminal and receives sampling signals characterizing circuit data of the intelligent dual-control switch. The control module is connected to the metering module and the switch module. The control module can receive the sampling signals and generate corresponding control commands based on the sampling signals. The switch module can select either of the two output terminals to connect based on the control commands.

[0008] In some possible implementations, the circuit data includes the voltage at the output terminal, the current flowing through the output terminal, and the power at the output terminal.

[0009] In some possible implementations, the control module stores a threshold range for abnormal data. When the switch module is connected to an output terminal, if the circuit data is within the threshold range for abnormal data, the control module can generate a corresponding control command, and the switch module can switch to connect to another output terminal in response to the control command.

[0010] In some possible implementations, the intelligent dual-control switch also includes a signal transmission module, which is electrically connected to the control module and also communicatively connected to a fixed terminal. The signal transmission module can receive sampling signals and send them to the fixed terminal, enabling the fixed terminal to perform corresponding displays.

[0011] In some possible implementations, the intelligent dual-control switch can communicate with a mobile terminal through a signal transmission module. The signal transmission module can obtain the control commands sent by the mobile terminal and transmit the control commands to the control module. The control module responds to the control commands and controls the switch module to select either of the two output terminals for connection.

[0012] In some possible implementations, the switch module includes a switch control unit and a switching switch. The switching switch includes a control terminal and is electrically connected to the switch control unit via the control terminal. One end of the switching switch is connected to the input terminal. The switch control unit can control the switching switch to connect to either of the two output terminals in response to a control command.

[0013] In some possible implementations, the input terminal is connected to the live wire, the intelligent double-pole switch can be connected to another double-pole switch, and the two output terminals can be electrically connected to the two terminals of the double-pole switch.

[0014] In some possible implementations, the input terminal is connected to the load, the intelligent double-control switch can be connected to another double-control switch, and the two output terminals can be electrically connected to the two terminals of the double-control switch.

[0015] Secondly, this application also provides a load circuit, which includes a double-control switch, a load connected to the double-control switch, and the aforementioned intelligent double-control switch, wherein the double-control switch is also connected to the intelligent double-control switch.

[0016] In some possible implementations, the load circuit also includes a fixed terminal that is communicatively connected to at least one smart double-control switch. The fixed terminal is able to acquire the sampling signals of each smart double-control switch and determine the total power consumption based on the sampling signals.

[0017] The intelligent dual-control switch provided in this application collects circuit data through a metering module and sends the circuit data to the control module in the form of a sampling signal. The control module can switch the output terminal that is connected to the input terminal according to the circuit data, and accurately monitor the circuit data of the load while realizing intelligent control of the switch state, thereby improving energy-saving efficiency.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0023] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0024] like Figure 1As shown, this application provides an intelligent dual-control switch 100, which includes one input terminal, two output terminals, a switch module 11, a metering module 12, and a control module 13. One end of the switch module 11 is always connected to the input terminal, and the other end of the switch module 11 can be connected to one of the two output terminals. The metering module 12 includes two sampling terminals, each connected to one output terminal. The two sampling terminals can receive sampling signals from the output terminals they are connected to, and the sampling signals can characterize the circuit data of the intelligent dual-control switch 100. The control module 13 connects the metering module 12 and the switch module 11. The control module 13 can receive the sampling signals and generate corresponding control commands based on the sampling signals. The switch module 11 can select either of the two output terminals to connect according to the control commands, thereby changing the switching state of the intelligent dual-control switch 100.

[0025] With the above settings, the metering module 12 used for sampling is integrated into the intelligent dual-control switch 100, which can accurately monitor the circuit data of the load while realizing intelligent control of the switch status, thereby improving energy efficiency.

[0026] In some possible implementations, the control module 13 includes a microcontroller unit (MCU) with a built-in analog-to-digital converter (ADC) used to convert the sampled signal into a digital signal. The metering module 12 includes a current detection unit and a voltage detection unit. The current detection unit can be either a current transformer or a Hall sensor, and the voltage detection unit can be either a voltage divider detection unit or a differential amplifier. The sampled signal received by the metering module 12 can characterize the circuit data measured by the current and voltage detection units. After receiving the sampled signal, the control module 13 converts the sampled signal into a digital signal using the ADC.

[0027] In some possible implementations, the two sampling terminals are defined as the first sampling terminal and the second sampling terminal, and the two output terminals are defined as the first output terminal and the second output terminal. The first sampling terminal is connected to the first output terminal, and the second sampling terminal is connected to the second output terminal.

[0028] If the input terminal is connected to the first output terminal, the first sampling terminal can receive the sampling signal at the first output terminal and send the sampling signal to the control module 13; if the input terminal is connected to the second output terminal, the second sampling terminal can receive the sampling signal at the second output terminal and send the sampling signal to the control module 13. The control module 13 stores a threshold range for abnormal data. When the switch module 11 is connected to one output terminal, if the circuit data is within the threshold range for abnormal data, the control module 13 can generate a corresponding control command, and the switch module 11 can switch to connect to the other output terminal in response to the control command.

[0029] Specifically, the circuit data includes the output voltage, the current flowing through the output, and the output power. If the circuit data is within the threshold range of abnormal data, the following abnormal operating states of the load can be obtained based on the abnormal circuit data: if the output voltage is too high, the load is in an overvoltage state; if the output voltage is too low, the load is in an undervoltage state; if the current flowing through the output is too high, the load is in a short-circuit state; if the current flowing through the output is too low, the load is in an undercurrent state; if the output power is too high, the load is in an overload state; if the output power is too low, the load is in an underload state.

[0030] Since the control module 13 can always receive sampling signals and monitor changes in circuit data, the intelligent double-control switch 100 can statistically analyze the power consumption of the load based on changes in the switching state of the intelligent double-control switch 100 and changes in circuit data.

[0031] By monitoring the circuit data of the load, it is possible not only to determine whether the load is in an abnormal working state and thus change the switching state of the intelligent double-control switch 100, but also to accurately calculate the power consumption of the load based on the circuit data, thereby improving energy efficiency.

[0032] In some possible implementations, the intelligent dual-control switch 100 can interact with a fixed terminal. The intelligent dual-control switch 100 also includes a signal transmission module 14, which is electrically connected to the control module 13 and also communicatively connected to the fixed terminal. This communication connection can be either wired or wireless. When the communication connection is wired, the signal transmission module 14 serves as a communication interface, connected to the fixed terminal via a signal line. When the communication connection is wireless, the signal transmission module can be any one of a Wi-Fi module, Bluetooth module, or Zigbee module. The signal transmission module 14 can receive sampling signals and send them to the fixed terminal, which can then respond to the sampling signals with corresponding displays.

[0033] For example, the fixed terminal can be a control panel. The control panel can receive and respond to sampling signals, process and store the circuit data represented by the sampling signals, including power consumption, and display the stored circuit data by operating the control panel, thus realizing the visualization of the circuit data and facilitating the monitoring of the load connected to the intelligent double-control switch 100. The control panel can also remotely control the intelligent double-control switch 100, facilitating the switching of the intelligent double-control switch 100's on / off state.

[0034] In some possible implementations, the intelligent dual-control switch 100 can interact with a mobile terminal. The intelligent dual-control switch 100 also includes a signal transmission module 14, which is wirelessly connected to the mobile terminal. The signal transmission module 14 can be any one of a Wi-Fi module, a Bluetooth module, or a Zigbee module. The signal transmission module 14 can receive sampling signals and send them to the mobile terminal, which can then respond to the sampling signals by performing corresponding displays.

[0035] For example, the mobile terminal can receive and respond to sampling signals, process and store the circuit data represented by the sampling signals, including power consumption, and display the stored circuit data by operating the mobile terminal, thereby visualizing the circuit data and facilitating monitoring of the load connected to the intelligent double-control switch 100. The mobile terminal can also remotely control the intelligent double-control switch 100, facilitating switching the on / off state of the intelligent double-control switch 100.

[0036] like Figure 2 As shown, in some possible implementations, the switch module 11 includes a switch control unit 111 and a switch 112. The switch 112 includes a control terminal and is electrically connected to the switch control unit 111 through the control terminal. One end of the switch 112 is connected to the input terminal. The switch control unit 111 is connected to the control module 13. The switch control unit 111 can respond to the control command sent by the control module 13 and control the switch 112 to connect to either of the two output terminals, thereby realizing the control of the intelligent dual-control switch 100.

[0037] like Figure 3 As shown, in some possible implementations, the intelligent double-pole switch 100 can be connected to another double-pole switch 200. The double-pole switch 200 includes two terminals and a common terminal, with one of the two terminals connected to the common terminal. The input terminal of the intelligent double-pole switch 100 is connected to the live wire, the first output terminal of the intelligent double-pole switch 100 is electrically connected to one terminal of the double-pole switch 200, and the second output terminal of the intelligent double-pole switch 100 is electrically connected to the other terminal of the double-pole switch 200.

[0038] like Figure 4 As shown, in some possible implementations, the input terminal of the intelligent double-control switch 100 is electrically connected to the load 300, the intelligent double-control switch 100 can be connected to another double-control switch 200, the first output terminal of the intelligent double-control switch 100 is electrically connected to one terminal of the double-control switch 200, the second output terminal of the intelligent double-control switch 100 is electrically connected to the other terminal of the double-control switch, one end of the common terminal of the double-control switch 200 is connected to one of the two terminals of the double-control switch 200, and the other end of the common terminal of the double-control switch 200 is electrically connected to the live wire.

[0039] This application also provides, as follows: Figure 3 The load circuit shown includes, in addition to the aforementioned intelligent double-control switch 100, a double-control switch 200 and a load 300. The intelligent double-control switch 100 and the double-control switch 200 are connected in series, and one of the intelligent double-control switches 100 and 200 is connected in series with the load 300.

[0040] Specifically, the double-pole switch 200 includes two terminals and a common terminal. One of the two terminals of the double-pole switch 200 is connected to the common terminal. One terminal of the double-pole switch 200 is electrically connected to the first output terminal of the intelligent double-pole switch 100, and the other terminal of the double-pole switch 200 is electrically connected to the second output terminal of the intelligent double-pole switch 100. The common terminal of the double-pole switch 200 is electrically connected to the load 300. The input terminal of the intelligent double-pole switch 100 is electrically connected to the live wire.

[0041] like Figure 4 As shown, in some possible implementations, the load circuit includes, in addition to the aforementioned intelligent double-control switch 100, a double-control switch 200 and a load 300. The double-control switch 200 includes two terminals and a common terminal. One of the two terminals of the double-control switch 200 is connected to the common terminal. The common terminal of the double-control switch 200 is electrically connected to the live wire. One terminal of the double-control switch 200 is electrically connected to the first output terminal of the intelligent double-control switch 100, and the other terminal of the double-control switch 200 is electrically connected to the second output terminal of the intelligent double-control switch 100. The input terminal of the intelligent double-control switch 100 is electrically connected to the load 300.

[0042] When the load circuit is on, if an abnormality occurs in the load circuit, such as a short circuit, the intelligent double-control switch 100 can respond to the abnormality and switch the output terminal of the intelligent double-control switch 100 connected to the input terminal of the intelligent double-control switch 100 to cut off the load circuit and thus protect the load circuit.

[0043] In some possible implementations, the load circuit also includes a fixed terminal 400, which is communicatively connected to at least one smart double-control switch 100. The fixed terminal 400 is able to acquire the sampling signals of each smart double-control switch 100 and determine the total power consumption based on the sampling signals.

[0044] By monitoring the circuit data of the load, the power consumption of the load can be accurately calculated based on the circuit data, thereby improving energy efficiency.
