[0023] The invention provides an intelligent switch.

[0024] Please refer to Figure 1 In this embodiment, the smart switch is used to connect at least one electrical device to a power source, and includes a communication module 100, a display module 200, an electricity metering module 300, and a control module 400 connected to the communication module 100, the display module 200 and the electricity metering module 300; the electricity metering module 300 is used to obtain the electricity consumption parameters of the electrical device and send the electricity consumption parameters to the control module 400; the control module 400 includes a storage unit and a calculation unit, the storage unit is used to store the target characteristic parameters of the electrical device, the calculation unit is used to obtain the real-time characteristic parameters of the electrical device connected to the smart switch according to the electricity consumption parameters, and compare the real-time electricity consumption parameters with the target parameters in the storage unit to obtain the type of the electrical device connected to the smart switch; the control module 400 sends the type of the electrical device to the display module 200 for display; the communication module 100 is used to send the working status information of the smart switch to the terminal device and obtain the control instructions sent by the terminal device, and send the control instructions to the control module 400 to control the on-off state of the smart switch.

[0025] It is understandable that all electrical equipment has its own unique impedance, inductive reactance, capacitive reactance, and resistance to ground, which manifests itself as current waves, phase angles, voltage fluctuations, harmonic feedback, and ground current during use. For example, after the control circuit of a refrigerator has been running for a period of time, the compressor will definitely run. If it does not run for a long time, the refrigerator is likely to be broken. After the compressor has been running for a period of time, it will definitely stop. If it does not stop for a long time, the refrigerator door may not be closed. Specifically, the instantaneous power, power factor, and capacitive and inductive loads can be determined through the real-time voltage and current curves. The power change of the electrical equipment can be determined by taking the differential, and the power can be collected by taking the integral. Through this information combined with several types of electrical equipment commonly used in the home, the equipment in use can be determined. These target characteristic parameters of the electrical equipment are stored in the storage unit. When the calculation unit analyzes the real-time characteristic parameters of the electrical equipment actually electrically connected to the smart switch based on the power consumption parameters obtained by the power metering module 300, the type of the electrical equipment electrically connected to the smart switch can be obtained by comparing it with the target characteristic parameters, and it can be displayed on the display module 200. Furthermore, the terminal device can know the operating status of the electrical equipment and control it at any time. Of course, the user can also reasonably arrange the power consumption time according to the power consumption of the electrical equipment, so as to achieve the purpose of saving electricity.

[0026] In the technical solution proposed by the present invention, by comparing the real-time characteristic parameters of the electric device connected to the smart switch with the target characteristic parameters stored in the storage unit, the type of the electric device connected to the smart switch can be obtained, and then displayed on the display module 200, so that the user can know the electric device controlled by the smart switch, which is convenient to use. In addition, the smart switch is provided with a communication module 100, which can exchange data with the terminal device, and the terminal device can remotely obtain the working status information of the smart switch, and can also remotely control the on and off status of the smart switch, which is convenient to use.

[0027] Among them, the communication module 100 can be a WiFi communication module, a ZigBee communication module, etc.; the terminal device can be a mobile phone, a tablet computer, a desktop computer, a smart wearable device, etc.; the working status information includes the on and off status of the smart switch, power consumption parameters and at least one of the types of power-consuming devices electrically connected to the smart switch.

[0028] Preferably, the control module 400 transmits the power consumption parameters to the display module 200 for display. The power consumption parameters such as real-time energy consumption statistics, cumulative energy consumption statistics, voltage, current and power measured by the power metering module 300 are also displayed on the display module 200, so that the user can intuitively obtain the power consumption of the power-consuming equipment corresponding to the smart switch, which promotes the user to save energy.

[0029] In one embodiment of the present invention, the control module 400 includes a normal working mode and an away working mode stored in a storage unit. When the user selects the away working mode, the control module 400 cuts off or connects the power supply of the electrical device from time to time. Specifically, an operation button for mode switching is set on the display module 200, and the user selects different working modes of the switch by controlling the operation button. Of course, the working mode of the switch can also be selected through the terminal. When the smart switch is in the away working mode, the electrical device will be turned on or off from time to time to create a scene where someone is at home, so as to achieve the purpose of active anti-theft, which is simple and efficient. For example, when the smart switch is connected to a table lamp and a TV, when the smart switch is connected to the power supply, the table lamp and the TV are turned on. In addition, when the user selects the away working mode, if the smart switch is turned on by mechanical triggering, such as a button is operated or a button on the display module 200 is manually operated, the control module 400 sends an alarm message to the terminal device.

[0030] In another embodiment of the present invention, the smart switch further includes a timing module connected to the control module 400, which is used to set the automatic shutdown time. The control module 400 controls to cut off the power supply of the already electrically connected electrical device according to the automatic shutdown time. The user can control the working time period of the electrical device connected to the smart switch according to actual needs, so as to achieve a better experience effect.

[0031] Preferably, the intelligent switch further comprises an output current limiting protection circuit, an output overvoltage protection circuit and an output short circuit protection circuit connected to the electrical equipment, and the output current limiting protection circuit, the output overvoltage protection circuit and the output short circuit protection circuit are respectively connected to the control module 400. When the output signal of the power supply exceeds the rated current, the rated voltage or a short circuit fault occurs, a signal for controlling the intelligent switch to be disconnected is sent to the control module 400, thereby stopping the output of electrical energy.

[0032] Preferably, the smart switch further includes a photosensitive sensor connected to the display module 200. When the indoor light is dim, the photosensitive sensor sends a signal to the display module 200 to control the display module 200 to light up, and the display module 200 acts as a night light. Of course, an LED light can also be set on the smart switch, and the photosensitive sensor is connected to the LED light to illuminate the user by lighting the LED light.

[0033] Preferably, the smart switch also includes a voice recognition module connected to the control module 400, and the control module 400 is used to cut off or connect the power supply of the electrical device according to the control instruction obtained by the voice recognition module. The user can control the smart switch by voice, and the smart switch is more intelligent.

[0034] The present invention also proposes an intelligent switch control system, which includes a host computer control device and an intelligent switch as described above, wherein the number of intelligent switches is at least one, and the intelligent switch and the host computer control device perform data exchange through a communication module 100, and the host computer control device is used to obtain a control instruction of a preset intelligent switch sent by a terminal device, and send the control instruction to the preset intelligent switch to control the on / off state of the preset intelligent switch. The specific structure of the intelligent switch refers to the above embodiment, and since the present intelligent switch control system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0035] Preferably, the host computer control device includes a touch panel, on which the working status information of all the intelligent switches in the intelligent switch control system is displayed or hidden, and the touch panel is provided with a control button for controlling the intelligent switches. For example, the intelligent switch control system includes a first switch, a second switch and a third switch, and the working status information of the first, second and third switches can be displayed on the host computer control device, and the user can also choose to hide some of the switches to avoid misoperation. It is understandable that the host computer control device can be any intelligent switch in the intelligent switch control system, that is, one of the intelligent switches among several intelligent switches is the main control switch; it can also be a handheld device such as a remote control.

[0036] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
