Description

Wireless control system and wireless control method for realizing power supply on-off operation of equipment

Technical Field

The present invention relates to the field of switch control technologies, and in particular, to a wireless control system and a wireless control method for implementing power supply on/off operation of a device.

Background

With the increasing warming of global climate, energy conservation and emission reduction become important in government work of various countries, especially in electrical appliances, electronic industries and the like closely related to daily life and production, the wave tip of the air inlet is pushed down, for example, in the market of europe and america, high efficiency and low power consumption become one of important factors which must be considered in the research and development process of electronic products, and the electronic products have market competitiveness.

The standby power consumption of various electronic devices becomes one of the important problems to be solved for energy conservation and emission reduction, however, many devices adopting wireless remote control technology, such as televisions, air conditioners, and the like, still have some problems and disadvantages in the use process. For example, as shown in fig. 1, when the device 80 is in a remote controllable state, i.e., when waiting for the command data signal S to be sent from the wireless remote controller 90 at the remote control end, the power switch in the device 80 must be in an open state, for example, the active standby watch circuit 810 therein needs to be powered on all the time, so that the power consumption in the standby state becomes an irrevocable problem. According to the test, if 1 watt standby power consumption is taken as an example, the power consumed by a common electric appliance for 1 year is close to 10 kilowatt hours. In addition, according to statistical data, the average standby energy consumption of urban families in China in 2009 reaches about 10%, which is equivalent to that each family uses 15-30W of Changming lantern. It follows that the amount of energy consumed by the existing large number of appliances for this space can reach an amazing level. Therefore, reducing the ubiquitous standby energy consumption of various electrical appliances becomes a major technical problem for building a social conservation and implementing an energy-saving, emission-reducing and environment-friendly strategy.

Although various zero power standby schemes have been proposed to address the standby power consumption problem, these schemes still suffer from a number of problems and require further improvement and sophistication. For example, since the control signal of the existing wireless switch remote control device needs to cover a certain range to achieve convenience in operation, accurate directional transmission cannot be used, and the loss ratio of the wireless energy transmission, reception and conversion process is large, so that the wireless energy transmission efficiency is not high, the ratio of the energy finally absorbed and utilized by the wireless switch device is very low, and most of the energy is radiated to the air and wasted. For another example, the existing wireless switch remote control device needs to consume large wireless energy, and even if the remote control end is powered by a high-price and large-capacity battery, the working life of the remote control device is greatly limited, and the cost is increased. For another example, if it is considered that a certain range of coverage of the remote control signal of the wireless switching device needs to be ensured, and particularly, accurate directional transmission is desired, higher requirements are put on the wireless switching remote control device (especially, two parts of a power amplifier and a transmitting antenna), while the requirements are difficult to be met by the existing common power amplifier and an onboard patch antenna, so that if the wireless switching device is applied, the volume of the remote control end needs to be increased, which brings many adverse effects on daily application, manufacturing cost and the like.

It should be noted that the foregoing description is provided to facilitate a better understanding of the invention and should not be construed as prior art only by virtue of the inclusion in this section or that all such problems or disadvantages noted therein are readily apparent.

Detailed Description

First, it should be noted that the structures, compositions, steps, features, advantages and the like of the wireless control system and the wireless control method for realizing the power supply on-off operation of the device of the present invention will be specifically described below by way of examples, however, all the descriptions are only for illustrative purposes and should not be construed as forming any limitation to the present invention. In this document, the technical terms "first", "second", etc. are used for distinguishing expression purposes only and are not intended to indicate their order, size, relative importance, etc., and the technical term "used" should not be construed as a limiting expression limited thereto, and the technical term "connected" and its derivatives mean that a specific component is directly and/or indirectly connected to another component, and the technical terms "transceiving antenna" and "transceiving antenna" are used for distinguishing expression purposes only, and they also have a function of transmitting and receiving wireless signals.

Furthermore, any single feature described or implicit in an embodiment or any single feature shown or implicit in the drawings or shown or implicit in the drawings, may still allow any combination or permutation to continue between the features (or their equivalents) without any technical barriers and thus further embodiments according to the invention should also be considered within the scope of this disclosure.

The invention firstly provides a wireless control system which can be used for realizing the power supply on-off operation of equipment. In general, a wireless control system according to the present invention may comprise two parts, namely a wireless switching device and a wireless remote control device adapted for use therewith. The general operating principle of the passive standby mode in one example of the present wireless control system is shown in fig. 2 only in a schematic way. Referring to fig. 2, the controlled standby device 80 is provided with a wireless switch device a according to the system of the present invention, for example, the wireless switch device a may be embedded in the device 80, while a wireless remote controller 90, which can be used as a wireless remote controller in the present invention, can be embedded with a wireless switching remote controller B, which is generally small in size and low in power consumption, the wireless switching remote control B, which is matched to the above-mentioned wireless switching device a, can send out, for example, a wireless switching signal S' (or called wireless energy signal) which is usually of low power to remotely control the wireless switching device a, for switching on and off the power supply 70 (which may take the form of a battery, ac power source, dc power source, etc.) to one, some or all of the device functional modules in the device 80, one such device functional module has been exemplarily labeled in fig. 2 with reference numeral 820.

Specifically, as shown in fig. 2, when the device 80 is required to start operating, for example, the wireless remote controller 90 is operated to send out a wireless switch signal S 'required to turn on the power supply 70 through the wireless switch remote control device B, and the wireless switch device a is operated to turn on the power supply of the device 80 after receiving the wireless switch signal S', and the composition, operation mode, and the like of the wireless switch device a will be described in more detail below. After the controlled device 80 and the controlled power supply 70 are powered on by the wireless switch device a, the wireless remote controller 90 can be used to continuously send various command data signals S to the device 80 to remotely control the device 80 to perform various possible operations, and such command data signals S may be the same or different under different application environments (such as facing different types of devices). Similarly, in the case where the apparatus 80 needs to stop operating (such as work is already completed, emergency stop or pause is needed, etc.), the wireless remote controller 90 may be operated to cause the wireless switch remote control device B to send out a corresponding wireless switch signal S' to instruct the wireless switch device a to operate to cut off the current power supply of the power supply 70 to the apparatus 80, so as to completely realize the zero-power standby of the apparatus 80.

Continuing with fig. 3 and 4, the wireless switching device in the system according to the invention will now be described in detail by way of the embodiments shown in these two figures.

Referring to fig. 3, there is illustrated in a schematic manner the general construction of a first embodiment of a wireless switching device in the system of the present invention. In this embodiment, the wireless switching device 100 may include a transceiver antenna 10, a passive wake-up module 20, a control module 30, an environmental energy collection and storage unit 40, and a controlled module 50, and the power supply 70 shown in fig. 3 may employ, for example, a battery or a dc power source to supply power to the apparatus 80.

Specifically, the transceiving antenna 10 is configured to receive and transmit wireless signals, i.e. it can not only receive wireless signals such as wireless energy signals, command data signals, etc., which are typically transmitted by a user operating a wireless remote control 90 located at a remote control end as shown in fig. 2, but also transmit signals (such as operation feedback signals, etc.) to be transmitted to the outside, which are received by the wireless remote control 90.

For the passive wake-up module 20, it is connected to the transceiving antenna 10 for recovering the pulse signal from the wireless energy signal received by the transceiving antenna 10, and using the pulse signal to switch on the above-mentioned environmental energy collecting and storing unit 40 to power the control module 30, which will be described in detail later. Because the pulse signal is a discrete signal which has the characteristics of repeated change and the like different from a common level signal, the scheme of the invention adopts a pulse signal mode which can be different from other modes such as a direct current signal and the like, thereby being capable of more fully meeting various practical requirements which may exist in different application occasions. The pulse signal may be continuously supplied or supplied only within a preset time range as required in a specific application, and specific parameters (such as width, amplitude, etc.) of the pulse signal may also be flexibly set according to specific application requirements, for example, the pulse signal may be controlled to maintain an electrical connection state between the control module 30 and a power supply source supplying power to the device 80 before a disconnection operation is not performed between the device and the power supply 70.

As an exemplary case, the passive wake-up module 20 may be configured to have a wireless energy receiving and converting unit 210, a first switch driving unit 220, and a switch 230. The first switch driving unit 220 is an optional configuration, and in practical applications, whether the first switch driving unit 220 needs to be used or not can be selectively determined according to specific operating conditions of the switch 230. If the first switch driving unit 220 is used, one end thereof may be connected to the wireless energy receiving and converting unit 210 as shown in fig. 3, and the other end thereof may be connected to a control end of the switch 230 (e.g., using a monostable switch, etc.) for outputting a driving signal matched to the switch.

As shown in fig. 3, one end of the wireless energy receiving and converting unit 210 is connected to the transmitting and receiving antenna 10, and the other end is connected to the switch 230 or the first switch driving unit 220 (if selected), and the wireless energy receiving and converting unit 210 is used to receive wireless energy and convert it into a pulse signal. The first switch driving unit 220 can be powered by the pulse signal generated by the conversion of the wireless energy receiving and converting unit 210 and the electric energy provided by the environmental energy collecting and storing unit 40 before and after the switch 230 enters the closed state, which are schematically indicated by the reference numerals a and d in fig. 3.

As will be appreciated by those skilled in the art, the switch 230 may be implemented by any suitable component, unit or module, such as a monostable switch, and may have its control terminal connected to the wireless energy receiving and converting unit 210, or alternatively to the first switch driving unit 220, and the other two terminals of the switch 230 are connected to the environmental energy collecting and storing unit 40 and the control module 30, respectively. When the control terminal of the switch 230 receives the pulse signal generated by the conversion of the wireless energy receiving and converting unit 210, it will enter a closed state to connect the electrical connection between the environmental energy collecting and storing unit 40 and the control module 30, so that the latter can be supplied with electric energy.

The environmental energy collection and storage unit 40 is configured to collect and store environmental energy (e.g., light energy, wind energy, heat energy, vibrational energy, chemical energy, etc.) to convert such environmental energy into electrical energy for output. As shown in fig. 3, in the wireless switch device 100, the output terminal of the environmental energy collecting and storing unit 40 is connected to the switch 230, and when the switch 230 is in a closed state, the electric energy output from the environmental energy collecting and storing unit 40 can be supplied to the control module 30 via the connection line a to start the operation thereof. It should be appreciated that the present invention allows the ambient energy collection and storage unit 40 to utilize ambient energy in any form including, but not limited to, any one or any combination of wind, thermal, light, chemical, vibrational energy, etc.

The control module 30 is configured to perform demodulation processing according to the command data signal received by the transceiving antenna 10, so as to generate and output a control signal matched with the controlled module 50, and may also be configured to generate a feedback signal (for example, a signal for outputting to the passive wake-up module 20 to disconnect the current power supply to the control module 30) according to the execution result of some or all of the control signals, and the like, for example, and may transmit such a feedback signal to the outside through the transceiving antenna 10 when required by an application, so that the wireless remote control 90 may receive and obtain corresponding information therefrom.

As an example case, the control module 30 may be configured to have a signal demodulation unit 310, a decoding and control unit 320, and a second switch driving unit 330. The second switch driving unit 330 is an optional configuration, and in practical applications, whether the second switch driving unit 330 is needed or not can be selectively determined according to specific configuration conditions of the controlled module 50. If a second switch driving unit 330 is used, it may be connected at one end to the decoding and control unit 320 and at the other end to the controlled module 50 as shown in fig. 3, for outputting a driving signal matched to the controlled module 50. The second switch driving unit 330 receives the unified power from the environmental energy collecting and storing unit 40 to the whole control module 30 before the controlled module 50 enters the closed state, and receives the exclusive power from the power source 70 to the second switch driving unit 330 after the controlled module 50 enters the closed state, which is indicated by the connection line c in fig. 3.

The signal demodulation unit 310 is configured to receive the modulated command data signal and convert it into a digital signal after the switch 230 of the passive wake-up module 20 enters a closed state. The decoding and control unit 320 has one end connected to the signal demodulation unit 310, the other end connected to the controlled module 50 or the second switch driving unit 330 that has been selected to be configured, and another end connected to the switch 230 or the first switch driving unit 220 in the passive wake-up module 20 (if selected), when the switch 230 has been turned to the closed state and the signal demodulation unit 310 converts a digital signal, the decoding and control unit 320 decodes the digital signal to generate a specific instruction data signal.

In an alternative scenario, the decoding and control unit 320 may be arranged to perform the following operations on the resulting digital signal: firstly, decoding the digital signal to generate a corresponding instruction data signal (for example, usually demodulating an identification code, a control code and a check code carried in the digital signal), and then, performing data transmission correctness check on the obtained instruction data signal so as to confirm that no error exists in the transmission process; secondly, it is determined whether the obtained command data signal is sent to the wireless switching device, and if yes, a corresponding control signal is output according to the command data signal, and such control signal can be used for being transmitted to the controlled module 50 to complete a corresponding control operation.

With continued reference to fig. 3, the controlled module 50 may employ any suitable components or units, such as monostable switches, bistable switches, and the like. For the monostable switch, various types of NPN transistors, MOS transistors and the like can be adopted, and for the bistable switch, for example, DS1E-ML-DC1.5V and DS1E-ML2-DC1.5V and the like of the DS series of Panasonic can be adopted. When the controlled module 50 employs a monostable switch, the device 80 usually needs to output a signal to the monostable switch or a second switch driving unit (if selected) in the control module after being powered to maintain the on state of its own power supply line, and when the controlled module 50 employs a bistable switch, the device 80 usually does not need to output any control signal to the bi-monostable switch or the second switch driving unit described above after being powered, because the bistable switch can maintain a high-impedance output state at this time, and the power supply line will automatically maintain the on state. It should be noted, of course, that the various types of switching components, devices or modules, etc. referred to throughout this document are also permissible to be various other types of monostable switches, bistable switches, etc., such as magnetic switches, micromechanical (MEMS) switches, MOS switches, etc.

As shown in fig. 3, the controlled module 50 has an input terminal connected to the control module 30 for receiving the control signal, and other output terminals connected to the power source 70 and the device 80, respectively, so that the power line between the device 80 and the power source 70 can be switched on or off according to the control signal. Wherein, the device 80 can be connected to the input end of the controlled module 50 or the second switch driving unit 330 (if selected), when the controlled module 50 is, for example, in the form of a controlled switch (such as a monostable switch, a bistable switch, etc.) and is closed, the device 80 is powered by turning on the power supply 70, and then the control module 30 can output a control signal to the controlled module 50 or the second switch driving unit 330 (if selected) to control the power supply on-off operation as required.

Having described the general composition of the wireless switching device 100 shown in fig. 3, the following description will proceed to exemplarily describe the basic operation thereof. First, the transmitting/receiving antenna 10 waits for the reception of wireless signals including wireless energy signals. If the transceiver antenna 10 receives a wireless energy signal sent from, for example, the wireless remote controller 90 (which may be provided with the wireless switch remote control device B) shown in fig. 2, the wireless energy receiving and converting unit 210 in the passive wake-up module 20 converts the wireless energy signal into a pulse signal, and the pulse signal can directly (or after performing, for example, signal amplification processing via the optional first switch driving unit 220) drive the switch 230 to enter the closed state. When the switch 230 in the passive wake-up module 20 enters the closed state, the environmental energy collection and storage unit 40 can start to supply power to the control module 30 through the connection line b via the switch 230, the signal demodulation unit 310 in the control module 30 starts to convert the command data signal received from the transceiver antenna 10 into a digital signal, the decoding and control unit 320 receives the digital signal and decodes a specific command data signal therefrom, and can output a corresponding control signal according to the command data signal, and the control signal can directly (or after performing, for example, signal amplification processing via the optional second switch driving unit 330) drive the controlled module 50 to enter the closed state. Thereby, the power supply 70 may supply power (if selected) to the second switch driving unit 330 through the controlled module 50 via the connection line c. If the controlled module 50 employs a monostable switch, the device 80 may output a valid signal to maintain the controlled module 50 in a closed state, and if the controlled module 50 employs a bistable switch, the device 80 may output a high impedance state. To this end, the wireless remote controller 90 may stop sending the wireless energy signal, so that the switch 230 in the passive wake-up module 20 is turned off, and the environmental energy collection and storage unit 40 thereby stops supplying power to the control module 30; when the device 80 needs to be shut down, such as when it is done, a disconnect command may be sent from the wireless remote control 90 to disconnect the power supply 70, thereby causing the device 80 to return to a zero power consumption standby state (i.e., a passive standby state). Of course, in some applications, it is also possible to actively output a signal from the device 80 to the controlled module 50 or the second switch driving unit 330 (if selected) to disconnect the power supply, thereby returning itself to the zero power consumption standby state. In the above process, the transceiving antenna 10 may transmit wireless signals according to the application requirement, and any suitable information, such as control execution condition, control result feedback, etc., may be included in the wireless signals, which may be received by the wireless remote control device in the system of the present invention.

For a better understanding of the invention, another embodiment of a wireless switching device 200 in a system according to the invention is also shown in fig. 4. To avoid repetition, the embodiment of fig. 4, wherein the same or similar elements as in the embodiment of fig. 3 discussed above are described in great detail above and therefore reference is made directly to the detailed description of the corresponding parts, and therefore not repeated herein, unless otherwise specified.

First, in the wireless switch device 200 shown in fig. 4, the power source 70 may be an AC power source, and the wireless switch device 200 includes a transceiver antenna 10, a passive wake-up module 20, a control module 30, an environmental energy collecting and storing unit 40, and a controlled module 50, and an AC/DC unit 60 is additionally provided therein.

In this wireless switching device 200, the AC/DC unit 60 is an optional configuration, and it may be used simultaneously with the second switch driving unit 330 in the control module 30, for example. The AC/DC unit 60 is connected to the controlled module 50 and the device 80 at one end, and connected to the second switch driving unit 330 in the control module 30 at the other end, and is used to convert the power source 70 (e.g., performing transformation rectification processing, etc.) into a power source form suitable for the second switch driving unit 330 in the control module 30, so that power can be supplied to the second switch driving unit 330 in the control module 30 through the connection line e via the AC/DC unit 60 after the controlled module 50 enters the closed state.

With continued reference to fig. 2 and 5, a wireless remote control device is further provided in the wireless control system of the present invention for cooperating with the wireless switch device. In practical applications, the wireless remote control device may be implemented by using any suitable components, units, modules or devices, such as an electronic chip, a processor, etc., for example, fig. 5 illustrates an example of a wireless remote control device.

As shown in fig. 5, the wireless remote control device (also referred to herein as a wireless remote control) 90 may include a transmitting and receiving antenna 91, a remote control module 92, and a remote control module 92. The transmitting and receiving antenna 91 is used for transmitting and receiving wireless signals, which may include, but are not limited to, wireless energy signals, command data signals, and the like, for example, the transmitting and receiving antenna 91 may receive an outward transmission signal from the transmitting and receiving antenna 10. The remote control module 92 is connected to the transceiver antenna 91, and is used to receive user input operations, for example, the user can operate keys, a display device and/or network input to communicate his/her manipulation intention to the remote control module 92, which can perform corresponding processing according to the user input operations, so as to transmit corresponding wireless signals through the transceiver antenna 91. The remote control module 92 may also process a wireless signal received by the transmitting/receiving antenna 91 (e.g., an operation feedback result signal corresponding to a command data signal from the wireless remote control device 90 transmitted by the transmitting/receiving antenna 10).

By way of further illustration, the remote control module 92 may optionally be configured to have a signal modulation and demodulation unit 921, a codec and control unit 922, and a human-machine interaction unit 923, which may receive input operation information of a user (e.g., various possible control commands to switch on between the device 80 and the power supply 70, switch off between the device 80 and the power supply 70, etc.) in any one or more of a key, a display device, a network interaction, etc.

The signal modem 921 is disposed between the transmitting and receiving antenna 91 and the codec and control unit 922, and is configured to perform wireless modulation processing on the command data signal to be transmitted to the outside, and also to convert the wireless signal received from the transmitting and receiving antenna 91 into a digital signal and then supply the digital signal to the codec and control unit 922 for processing.

The codec and control unit 922 is disposed between the signal modem unit 921 and the human-computer interaction unit 923, and is configured to process the user input operation information received from the human-computer interaction unit 923 into a corresponding instruction data signal, and then provide the instruction data signal to the signal modem unit 921, and may also decode the digital signal generated by the signal modem unit 921 through conversion to obtain specific information, where such information may be displayed through the human-computer interaction unit 923 in any suitable manner (such as screen text, sound, light, and the like), so as to facilitate practical application, for example, enable a user to know a feedback result corresponding to a previous input operation thereof.

The wireless switching device according to the invention has been described above exemplarily by combining two different embodiments shown in fig. 3 and 4. It will be appreciated that when the device 80 is in the standby remote controlled state, the physical connection between its interior and the power supply 70 for supplying electrical energy is broken, and the device 80 is now in a completely power-free state, thus ensuring that the current standby power consumption of the overall system, including the wireless switching device, is zero. According to statistics, the generated energy of the whole three gorges can be offset only by the energy consumed by various national household appliances in standby mode every year, so that the popularization and the application of the scheme of the invention can save considerable energy consumption expenditure, and therefore, huge social and economic benefits can be generated.

Furthermore, as mentioned above, when the device 80 is in the passive standby state, the wireless energy signal received by the

wireless switch device

100 or 200 from the wireless remote control device 90 is only used to control the on/off of the switch 230 in the passive wake-up module 20 (i.e. to control when the power supply 70 supplies power to the control module 30), for example, a monostable switch built by an NPN tube is used as the switch 230, only a voltage of 0.7 volts and a current in the order of microamperes are required to drive the NPN tube closed, if conventional germanium transistors are used, only 0.3 volts and microampere levels of current are required, although many types of switches with lower power consumption are available for use with the present invention, therefore, the wireless switch device can work only with low radio frequency energy consumption and can use accurate directional transmission, therefore, a large amount of wireless energy is saved, and the waste caused by the radiation of a large amount of wireless energy to the air is avoided. It will be appreciated that even if a conventional size 5 battery, for example, is used in a wireless switch remote control unit which cooperates with the present wireless switch unit, the battery will have a desirable operating life, thereby not only facilitating the application, but also being capable of saving considerable operating costs in the case of large-scale applications. Meanwhile, the radio frequency energy consumption of the wireless switch remote control device can be effectively reduced, so that parts of a transmitting power amplifier, a transmitting antenna and the like of the wireless switch remote control device can obtain larger design space, and the miniaturization, integration and low cost can be realized more conveniently, so that the practicability of the whole system is obviously enhanced.

If the wireless switch device in various existing wireless control systems is compared with the device of the invention, the following common characteristics of the existing wireless control systems can be found: all the energy consumption required for implementing decoding and control, including before the power supply line between the controlled power supply and the controlled standby device is switched on, needs to be provided by the wireless energy transmitted by the existing wireless remote control. Because the control signal of the wireless remote control device covers a certain range to realize the convenience in operation, the loss of the wireless energy transmission, reception and conversion process is larger, and finally, the proportion of the wireless energy which can be effectively absorbed and utilized to the total transmitted wireless energy is very low. Assuming that a certain wireless switch device needs 10 milliwatts of power for each decoding and control operation, if all the wireless energy transmitted by the wireless remote control device is provided, because the transmission efficiency of the wireless energy is not high, the wireless remote control device may need to use 10 to 100 times of transmission power, i.e. 0.1 to 1 watt of wireless transmission power, so a high-price and large-capacity battery is usually needed, however, most of the transmitted wireless energy is still radiated to the air and wasted. The above situations cause the defects and shortcomings of the existing wireless remote control device in aspects such as battery service life, use cost, space volume optimization, component improvement, realization of accurate directional transmission and the like.

It should also be noted that in many areas, such as home homes, office buildings, factory buildings, etc., the wireless switching devices in the system of the present invention will not, or substantially will not, accidentally turn on power and equipment from outside interference. This is because the amplitude of the pulse signal recovered by the wireless energy receiving and converting unit in the wireless switch device is usually required to reach a certain level (for example, above 0.1 volt), and it is only possible to wake up the power supply to supply power to the control module in the wireless switch device, which is completely difficult to reach by the remote control signal. After a lot of practical tests, even if the mobile phone in the call state (or the networking state) is 0.1 meter away from the wireless switch device, the wireless switch device cannot recover the direct current of more than 0.1 volt at this time. In practical application, the wireless energy receiving and converting unit in the wireless switch device can be set to only absorb and process wireless energy signals within a certain frequency range according to different application requirements. In addition, since different appliances are often placed in different rooms, directions and heights, for example, the chance of placing two or more televisions (or refrigerators, air conditioners, etc.) in the same room, in the same direction and at the same height at the same time is very small, if it is noticed a little, the chance of waking up multiple devices simultaneously to decode is quite low in practical use and can be avoided at all.

According to the design idea of the invention, another technical scheme is provided, namely, a wireless control method for realizing the power supply on-off operation of equipment is provided. An example of the method of the present invention is given in fig. 6 for illustrative purposes. As shown in fig. 6, the wireless control method may include the steps of:

first, in step S11, a wireless control system designed according to the present invention for performing power on/off operation of a device may be provided, and a wireless switch device may be disposed between the device and a power source, for example, the wireless switch device may be directly integrated into the device, or may be used as an external device to be connected to both the device and the power source.

Then, in step S12, a wireless signal transmitted from a wireless remote control device in the wireless control system can be received by using a transmitting/receiving antenna in the wireless switch device, such wireless signals may include but are not limited to wireless energy signals, command data signals and the like, so that, in a subsequent step S13, the wireless energy signal therein can be used to generate the pulse signal as described above, and the pulse signal may be used to power a passive wake-up module in the wireless switching device, the latter will cause the power supply between the environmental energy collection and storage unit and the control module in the wireless switch device to be connected once the wireless switch device is powered on, the foregoing has been a description of the wireless switching device and its components in greater detail so that reference is made to the detailed description of the various parts thereof.

As shown in fig. 6, in the next step S14, the wireless switch device may be used to demodulate the command data signal received from its transmitting/receiving antenna to generate a specific control signal, and then the corresponding on or off operation between the power supply and the device may be performed according to such control signal.

The above is only an exemplary illustration of the radio control of the invention, it being understood that it fully allows a flexible application of the method of the invention according to the actual situation, without prejudice to the gist of the invention, so as to be able to better satisfy the various requirements which may be different.

For example, in step S12, the wireless switching device/wireless remote controller used may be constituted by only the wireless switching remote controller as described above and only needs to transmit a wireless energy signal to generate the pulse signal in the wireless switching device, but may have a function of transmitting a plurality of signals such as a wireless energy signal and a command data signal.

As another example, in the above step S14, a signal may be sent from the device to the wireless switch device after the device and the power supply are turned on, so that the controlled module in the wireless switch device may keep performing the turn-on operation between the device and the power supply.

For another example, as an optional case, in the above step S14, in a case where the device needs to stop operating, for example, an instruction data signal may be sent to the wireless switch device through the wireless switch device/wireless remote controller, for example, so as to cause the controlled module in the wireless switch device to perform an operation of disconnecting the device from the power source, so that the device is in the passive standby state, or the above process may also be implemented by sending a signal from the device to the wireless switch device to return the device to the passive standby state. With regard to the above alternative specific control modes, the method of the invention allows flexible setting selection according to different application occasions so as to better meet various actual requirements.

It should be understood that devices referred to throughout this document may include, but are not limited to, various types of electronic devices, devices in which such electronic devices are integrated, and the like, such as numerous types of electromechanical devices and the like that may be used in a home, office, business, or manufacturing, and the like. By applying the technical scheme of the invention, the power supply on-off connection of the devices can be effectively controlled, and especially, standby electric energy which is consumed by a large amount of air due to the adoption of the prior art can be saved, so that the invention has quite obvious technical advantages and can generate extremely considerable benefits.

The wireless control system and the wireless control method for implementing power supply on/off operation of the device according to the present invention have been explained in detail by way of examples only, and these examples are only for illustrating the principles of the present invention and the embodiments thereof, and are not to be construed as limiting the present invention, and various modifications and improvements can be made by those skilled in the art without departing from the spirit and scope of the present invention.
