Description

Wireless switch device, equipment system and power supply on-off operation control method

Technical Field

The present invention relates to the field of switch control technology, and in particular, to a wireless switch device, an apparatus system, and an apparatus power supply on-off operation control method.

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 existing large numbers of electrical 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, etc. of the wireless switchgear, the apparatus system, and the apparatus power supply on-off operation control method of the present invention will be specifically described below by way of examples, however, all the descriptions are for illustrative purposes only, and they should not be construed as forming any limitation to the present invention. In this document, the technical term "connect" and its derivatives mean that a specific component is directly and/or indirectly connected to another component, the technical terms "first" and "second" are used for distinguishing expression purposes only and are not intended to indicate their order, size, relative importance and the like, and the technical term "used" should not be construed as a limiting expression only thereto.

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.

Referring initially to fig. 2, the general operating principle of an example of the apparatus of the present invention in a passive standby mode is schematically illustrated. As shown in fig. 2, the controlled standby device 80 is provided with a wireless switching device a according to the present invention, which may be embedded inside the device 80, for example, and a wireless remote control B, which is usually small in size and low in power consumption, may be embedded in a wireless remote controller 90 as a remote control end, and the wireless remote control B is matched with the wireless switching device a and may transmit a wireless switching signal S' (or referred to as a wireless energy signal) with usually low power to remotely control the wireless switching device a, for example, so as to switch on or off the power supply 70 (which may be in the form of a battery, an ac power supply, a dc power supply, or the like) to some, or all of the device function modules in the device 80, and one such device function module is exemplarily indicated by reference numeral 820 in fig. 2.

Specifically, 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 source 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.

Referring next to fig. 3 and 4, the wireless switch device of the present invention can be better understood by describing the embodiments shown in the two figures.

In fig. 3, the general construction of the first embodiment of the present wireless switching device is shown, in which the wireless switching device 100 may comprise a receiving 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 supply for supplying electric power to the apparatus 80.

Specifically, the receiving antenna 10 is configured to receive wireless signals, such as wireless power signals, command data signals, etc., which are typically transmitted by a user operating a wireless remote control 90, such as that shown in fig. 2, located at a remote control end. The passive wake-up module 20 is connected to the receiving antenna 10 for recovering the pulse signal from the wireless energy signal received by the receiving antenna 10, and the pulse signal is used 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. In a specific application, the pulse signal can be continuously supplied or supplied only within a preset time range according to needs, and specific parameters (such as width, amplitude and the like) of the pulse signal also allow flexible setting according to specific application requirements.

As an alternative, 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 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.

For the switch 230, it may be implemented by any suitable device, unit or module, such as a monostable switch, and its control terminal may be connected to the wireless energy receiving and converting unit 210, or alternatively, 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 a component of the wireless switching device 100 and 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 based on the command data signal received by the receiving antenna 10, so as to generate and output a control signal matched with the controlled module 50. Merely as an exemplary case, the control module 30 may be provided 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 application, whether the second switch driving unit 330 needs to be used or not can be determined according to the specific configuration 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), and after the switch 230 has been turned into a 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, etc. For the monostable switch, various 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 of the DS series of Panasonic company 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 the 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 after being powered, because the bistable switch can maintain the 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 an input terminal 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 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 made the above description of the example of fig. 3 aware of the general composition of the wireless switching device 100, the basic operating principles thereof will be described further below. First, the receiving antenna 10 waits for receiving wireless signals including wireless energy signals. If the receiving 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 receiving 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.

By way of further illustration, another embodiment of the present wireless switching device, a wireless switching device 200, is also schematically illustrated in fig. 4. To avoid repetition, the embodiments in fig. 4, which are the same as or similar to the embodiments in fig. 3 discussed above, may be referred to directly in the detailed description of the corresponding parts, unless otherwise specified, and are not repeated herein.

In the wireless switching device 200 shown in fig. 4, in which the power supply 70 may adopt an alternating current power supply, the wireless switching device 200 additionally includes an AC/DC unit 60 in addition to the receiving antenna 10, the passive wake-up module 20, the control module 30, the environmental energy collecting and storing unit 40 and the controlled module 50.

The AC/DC unit 60 is an optional configuration in the wireless switching device 200, and 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.

The wireless switching device according to the invention has been described above exemplarily by means of 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, thereby 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.

As described above, it can be understood that, when the device 80 is in the passive standby state, the wireless energy signal received by the

wireless switching device

100 or 200 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, and only a voltage of 0.7 v and a current of microampere are required to drive the NPN tube to close, and only a voltage of 0.3 v and a current of microampere are required if a conventional germanium tube is used, and of course, many types of switches with lower power consumption are available for the present invention to choose, so that the wireless switching device only needs low rf power consumption to operate, and can use precise directional transmission, thereby saving a large amount of wireless energy, and avoiding a large amount of wireless energy being radiated to the air and wasted. 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 achieve the desired operating life, thereby not only facilitating application, but also in the case of large-scale applications, at all, allowing considerable savings in operating costs. 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.

Comparing the existing various wireless switch devices with the present invention, it can be found that the common characteristics of these wireless switch devices are: 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, 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, due to the low transmission efficiency of wireless energy, and therefore, a high-price and large-capacity battery is usually needed, however, most of the transmitted wireless energy is wasted when being radiated into the air. 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 device according to the present invention does not, or substantially does not, accidentally switch on the power supply and the equipment due to external 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 distance between the mobile phone in the call state (or the networking state) and the wireless switch device is 0.1 meter, the wireless switch device cannot recover the direct current of more than 0.1 volt at the moment. 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, the probability 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, and therefore if some attention is paid to this, the probability of waking up multiple devices simultaneously to decode is quite low in practical applications and can be avoided at all.

According to the design concept of the invention, the invention also provides a method for controlling the power supply on-off operation of the equipment. An overview of an exemplary process flow of the method of the present invention is given in fig. 5. As shown in fig. 5, the device power supply on-off operation control method may include the steps of:

first, in step S11, the wireless switch device provided according to the present invention may be disposed between the device and the 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.

Next, in step S12, a receiving antenna in the wireless switch device may be used to receive a wireless signal from the outside, such a wireless signal may include, but is not limited to, a wireless energy signal, a command data signal, etc., so that in the following step S13, the wireless energy signal therein may be used to generate a pulse signal as described above, and the pulse signal may be used to power a passive wake-up module in the wireless switch device, and the latter, once powered, will cause the environmental energy collection and storage unit and the control module in the wireless switch device to be powered on.

Then, in step S14, the command data signal received from the receiving antenna may be demodulated using the wireless switching device to generate a specific control signal, and then the on operation or the off operation between the corresponding power supply and the device may be performed according to such a control signal.

The above is only an exemplary description of the present device power supply on-off operation control method, and it should be understood that it is entirely permissible to flexibly apply the present method according to practical situations so as to be able to better satisfy various possible different requirements without departing from the gist of the present invention.

For example, in step S12, a wireless remote controller matched with the wireless switch device may be provided, and the wireless remote controller is operated to transmit wireless signals such as wireless energy signals and command data signals. For example, such a wireless remote control may be configured only by the wireless switching remote control device as described above, and may generate the pulse signal in the wireless switching device by only transmitting the wireless energy signal, or may have a function of transmitting a plurality of signals such as the wireless energy signal and the command data signal. In addition, in some applications, the wireless switch device may be configured to receive wireless signals automatically transmitted by some devices, apparatuses, systems, etc. periodically or aperiodically, so as to implement automatic operation of the controlled apparatus periodically or aperiodically.

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

For another example, in an optional situation, in the above step S14, in a situation where the device needs to stop operating, for example, an instruction data signal may be sent to the wireless switch device through a wireless remote controller or the like, so as to cause the controlled module in the wireless switch device to perform an operation of disconnecting the device from the power supply, so as to cause the device to be 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.

In addition, the present invention provides a device, in which a wireless switch device, such as that exemplarily described above, can be provided so that the power supply on-off state between the device and the power supply can be controlled by the wireless switch device, thereby better solving the problems of the prior art, such as mentioned above, and achieving the outstanding technical advantages of the present invention over the prior art, discussed above, and achieving significant benefits. It should be understood that devices in accordance with the present invention 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 facility, and the like.

Generally, the wireless remote controller in the equipment system of the present invention can be realized by installing the above wireless switch remote controller in various existing wireless remote controllers. Of course, in some application occasions, the wireless remote controller in the equipment system may also be implemented only by the wireless switch remote control device, that is, the wireless remote controller is only used for sending a wireless switch signal (i.e., a wireless energy signal) to control the power supply on-off operation of the power supply to the equipment at this time, and for other operations of the equipment, the wireless remote control device may continue to use the common existing wireless remote control device to send a corresponding instruction data signal to the equipment, and the above implementation manners are all allowed by the present invention.
