Description

Technical Field

[0001] The present application relates to the field of wireless communication control, and in particular to a self-powered device, and a wireless control system and method based on the self-powered device. Background Art

[0002] Traditional wiring power supply is limited by the environment and location, while battery power supply is limited by reliability and lifespan, and neither is an environmentally friendly solution. Wireless devices with self-powered functions do not need to be connected to the circuit via cables or have built-in batteries. Instead, they convert mechanical energy into electrical energy by pressing the switch device to power the communication module inside the wireless switch. Therefore, they are widely used in the switch device control of electrical appliances.

[0003] Since the energy generated by self-powered wireless devices is small, it is only enough to transmit signals of tens of milliseconds (less than 50 milliseconds) for the communication circuit, and it does not have the ability to receive and process signals. Compared with Sub-2.4GHz (i.e. wireless communication in the frequency band below 2.4GHz), Sub-1GHz (i.e. wireless communication in the frequency band below 1GHz) uses lower transmission power to achieve the same connection distance. This makes Sub-1GHz very suitable for the application of self-powered wireless devices. At the same time, the Sub-1GHz band has the advantages of long distance and stronger penetration. Therefore, self-powered wireless devices are basically based on communication in the Sub-1GHz band.

[0004] However, the mainstream in the fields of smart home and commercial lighting is mainly based on 2.4GHz frequency band technology. Wi-Fi, Mesh, Beacon, etc., while devices based on the Sub-1GHz band need to use Sub-1GHz controllers and related modules or embed related chips to communicate with mainstream communication protocols, and cannot directly access the Bluetooth network. The configuration process of Bluetooth devices takes a long time and requires continuous signal reception, but self-powered devices cannot meet this requirement. This significantly increases the difficulty of access and the overall cost of the product, which also limits the application of self-powered wireless devices (such as: self-powered wireless switches, self-powered sensors, etc.) in smart homes and commercial lighting.

DETAILED DESCRIPTION

[0056] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0058] like Figure 1-Figure 4 As shown, the present application provides a self-powered device, including: a driving component 1 (such as a button), an energy collection and power generation module 4, a power management module 51 ( Figure 4 The solid line box in the upper part is the power management module 51 circuit) and the RF transmission module 52 ( Figure 4 The solid line box in the lower half is the circuit of the radio frequency transmission module 52). The power management module 51 and the radio frequency transmission module 52 are both accommodated in a printed circuit board assembly 5 (Print Circuit Board Assembly, PCBA).

[0059] The driving component 1 is connected to the energy collection and power generation module 4, and the driving component 1 is used to transmit the pressure applied to the driving component 1 to the energy collection and power generation module 4. For example, by pressing a button, the pressure is transmitted to the energy collection and power generation module 4, driving the energy collection and power generation module 4 to generate current.

[0060] The energy collection and power generation module 4 is used to generate electric energy according to the pressure on the driving component 1. The driving component 1 is arranged above the energy collection and power generation module 4; the energy collection and power generation module 4 includes: an internal power generation device (micro generator), pressing the driving component 1, driving the internal power generation device (micro generator) to complete the conversion of mechanical energy into electric energy, and the generator can generate electric energy, and its principle is: the action of external mechanical force drives the magnet group (magnetic field) to move up and down and continuously cut the magnetic flux lines, and the conductor coil generates an induced electromotive force.

[0061] The power management module 51 is electrically connected to the energy collection and power generation module 4 and the radio frequency transmission module 52 respectively; the power management module 51 is used to receive the electric energy and supply power to the radio frequency transmission module 52.

[0062] The radio frequency transmitting module 52 is used to transmit signal instructions; the radio frequency transmitting module 52 is a Bluetooth beacon device operating in the 2.4G frequency band; the signal instructions are used to control the electric device to access the Bluetooth network.

[0063] In another exemplary embodiment of the present application, the signal instruction is a 2.4G Bluetooth signal; the signal instruction includes: address, user information, key (encryption information) and key value. Among them, the address is a media access control (MAC) address, the user information is represented by a process identifier (PID), and the signal instruction contains information about the self-powered device.

[0064] In another exemplary embodiment of the present application, the sending time of the signal instruction is between 60ms-200ms.

[0065] In another exemplary embodiment of the present application, Figure 4 As shown, the process of the power management module 51 receiving the electric energy and supplying power to the RF transmitting module 52 specifically includes: the power management module 51 receives the alternating current generated by the energy collection and power generation module 4, and rectifies the alternating current ( Figure 4 The dotted box on the left side of the upper half is a rectifier circuit, which is rectified by a Schottky diode to obtain direct current, store the direct current, and transform the direct current to power the RF transmitter module 52 ( Figure 4 The dotted box on the right side of the upper part is the energy storage and voltage reduction circuit. The 2.4G Bluetooth power supply voltage is 1.2V-3.6V.

[0066] In another exemplary embodiment of the present application, Figure 1 As shown, the self-powered device further includes: a housing 2 ; the housing 2 is used to accommodate the energy collection and power generation module 4 , the power management module 51 and the radio frequency transmission module 52 .

[0067] In another exemplary embodiment of the present application, the housing 2 includes: a cover 21 and a bottom shell 22; the bottom shell 22 is closed on three sides. The cover 21 is detachably arranged on the upper part of the bottom shell 22; the driving component 1 is fixed on the upper part of the bottom shell 22, and the cover 21 is used to install the driving component 1 and enable the driving component 1 to be movably buckled on the cover 21.

[0068] The energy collection and power generation module 4 , the power management module 51 and the radio frequency transmission module 52 are integrated in the cavity of the bottom shell 22 .

[0069] In another exemplary embodiment of the present application, Figure 1 As shown, the self-powered device also includes: a waterproof silicone layer 3 (eg, a waterproof silicone pad) and a conductive lever 6.

[0070] The waterproof silicone layer 3 is disposed between the cover 21 and the energy collection and power generation module 4 , and the waterproof silicone layer 3 is used for waterproofing, conducting pressure, and reducing noise.

[0071] One end of the conductive lever 6 is fixedly connected to the electric energy triggering end of the energy collection and power generation module 4, and the other end of the conductive lever 6 extends outward; the pressure applied on the driving component 1 passes through the waterproof silicone layer 3 and acts on the conductive lever 6, and the conductive lever 6 drives the energy collection and power generation module 4 to generate electric energy. In this embodiment, by pressing the driving component 1 (button), the pressure passes through the waterproof silicone layer 3 and acts on the conductive lever 6, thereby driving the energy collection module to generate electric energy.

[0072] By applying pressure to the driving component 1, the pressure is transmitted to the top of the energy collection and power generation module 4 through the waterproof silicone layer 3. The energy collection and power generation module 4 generates AC power after being stressed and sends it to the power management module 51; the power management module 51 converts the AC power into DC power and stores the electric energy, and after voltage transformation, supplies power to the RF transmission module 52. The RF transmission module 52 is powered on and starts to transmit signal instructions.

[0073] In another exemplary embodiment of the present application, Figure 5 As shown, the driving component 1 (button) includes: a pressing end 11, a magnetic conductive sheet and a tongue core; the magnetic conductive sheet is fixedly connected to the pressing end 11, and the tongue core is used to cut the magnetic flux lines.

[0074] Figure 5 The working states shown are from top to bottom, A: in the initial state, the magnetic sheet and the tongue core are attracted; B: in the initial stage of pressing, the pressing end 11 drives the magnetic sheet to lift upward, and due to the action of the magnetic force, the magnetic sheet and the tongue core continue to be attracted, and the tongue core is deformed; C: in the later stage of pressing, the magnetic sheet and the tongue core are continuously pressed by external force and reach a critical value, disengage from the attraction, and rebound and vibrate at high speed; in this process, the tongue core cuts the magnetic lines of force, driving the energy collection and power generation module 4 to generate electricity; D: after the pressing is released, under the influence of the magnetic force, the magnetic sheet and the tongue core are attracted (restoring the initial state).

[0075] The principle of power generation of the energy collection and power generation module 4 is as follows: the external mechanical force drives the magnet group (magnetic field) to move up and down and continuously cut the magnetic flux lines, and the conductor coil generates an induced electromotive force.

[0076] This application can use self-powered devices to embed many devices with RF receiving modules, such as lighting, curtain control, electrical equipment, etc.

[0077] The RF receiving module has a built-in low-power 32-bit central processing unit (CPU), which can also serve as an application microcontroller (processor) and support low-power Bluetooth connection. It is used to perform signal processing on the data carried by the signal after receiving the signal instruction and confirm whether the signal instruction is a valid signal.

[0078] When the 2.4G self-powered device sends a valid signal, the RF receiving module with Bluetooth support and processor receives the data, parses the data and confirms the data. The process of receiving, parsing and confirming the data by the RF receiving module requires the following conditions: 1. The RF receiving module has the same transceiver protocol as the RF transmitting module 52; 2. The RF receiving module needs to learn the MAC (address), PID (user information) and key (encrypted information) transmitted by the RF transmitting module 52. The above three elements are used for identification, verification and verification of the RF receiving module; 3. The self-powered device is paired with the RF receiving module.

[0079] An embodiment of the present application also provides a wireless control system based on a self-powered device, which is used to control the power-consuming device to access the Bluetooth network according to the signal instructions transmitted by the radio frequency transmitting module 52 of the self-powered device; the self-powered wireless control system includes: a radio frequency receiving module and a processor.

[0080] The RF receiving module matches the self-powered device; the RF receiving module and the RF transmitting module 52 of the self-powered device use the same transceiver protocol; the RF receiving module supports Bluetooth function. Among them, the RF receiving module and the RF transmitting module 52 of the self-powered device use a 2.4GHz frequency band transceiver protocol.

[0081] The processor is respectively connected to the RF transmitting module 52 and the RF receiving module for communication; the processor is used to send a pairing instruction to the RF receiving module and a clearing instruction to the RF transmitting module 52 .

[0082] The radio frequency receiving module performs the following operations based on the pairing instruction.

[0083] Receive a signal instruction; determine whether the signal instruction is a valid signal; the valid signal is that the signal instruction adopts the transceiver protocol of the radio frequency transmitting module 52, and the signal instruction includes an address, user information and a key; the address, the user information and the key are used to identify the self-powered device.

[0084] If the signal instruction is a valid signal, it is determined whether the signal instruction is a signal instruction recognized for the first time; if the signal instruction is a signal instruction recognized for the first time, the radio frequency receiving module stores the signal instruction; if the signal instruction is a signal instruction recognized again, the radio frequency receiving module controls the power-consuming device to access the Bluetooth network according to the signal instruction.

[0085] If the signal instruction is an invalid signal, the RF receiving module does not take any action.

[0086] The RF transmitting module 52 deletes the signal instruction stored in the RF transmitting module 52 based on the clear code instruction.

[0087] In another exemplary embodiment of the present application, a function key is provided on the radio frequency receiving module; the function key is communicatively connected to the processor; and the function key is used to send the pressure time applied on the function key to the processor.

[0088] The process of the processor sending a pairing instruction to the radio frequency receiving module and sending a clearing instruction to the radio frequency transmitting module 52 specifically includes:

[0089] It is determined whether the pressure time applied to the function key is in the pairing time or the clearing time.

[0090] If the pressure time applied to the function key is within the pairing time, a pairing instruction is sent to the radio frequency receiving module.

[0091] If the pressure time applied to the function key is within the code clearing time, a code clearing instruction is sent to the radio frequency transmitting module 52 .

[0092] Furthermore, pressing and holding the function key with the RF receiving module puts the RF receiving module into a learning (pairing) state, or you can also click on the RF learning window through the application processing platform (Application, APP) to enter the learning (pairing) state; at this time, press the self-powered device, the RF transmitting module 52 sends an instruction, and the RF receiving module has learned and stored it in the corresponding device; when the self-powered device is triggered again, the RF receiving module can accurately identify the signal instruction; similarly, pressing and holding the function key with the RF receiving module can clear the information stored in the RF transmitting module 52 (which can be distinguished by time, such as: pairing 3 to 4 seconds, clearing code 6 to 8 seconds, etc.) or you can also click on the RF transmitting module 52 information clearing window through the APP to enter the deletion (clearing code) state.

[0093] like Figure 6 As shown, the overall workflow of the wireless control system based on the self-powered device in the above embodiment is as follows:

[0094] Step 1: drive the energy collection and power generation module 4 to generate electricity through external force.

[0095] Step 2: The radio frequency transmission module 52 starts to generate and send a signal instruction.

[0096] Step 3: After the signal instruction is sent successfully, the RF receiving module (RF module) obtains the signal instruction.

[0097] Step 4: Determine whether the signal instruction is valid.

[0098] Step 5: If it is a valid signal, the corresponding electrical equipment (relay) is driven to work; if it is an invalid signal, no action is taken.

[0099] In the step 4, determining whether the signal instruction is valid, the determination principle is:

[0100] To confirm a valid signal, the four elements of information, MAC (address), PID (user information), key (encryption information), and key value, must first be stored (learned) in the microcontroller.

[0101] Furthermore, relays are used to control the operation of electrical appliances. (Solutions such as thyristors and MOS tubes (Metal-Oxide-Semiconductor, Metal-Oxide Semiconductor Field Effect Transistors) can be used to control the operation of electrical appliances). When the RF receiving module receives a valid signal, it issues a control instruction, and the control instruction output can be a high or low level, a pulse (usually a periodic, short-term electrical signal), or a pulse width modulation (PWM) signal. It is used for the needs of different electrical appliances. Such as: smart lamps, smart sockets, smart curtains, dimmers and other smart devices.

[0102] Furthermore, the wireless control system based on the self-powered device is provided with an Over-the-Air (OTA) upgrade mechanism to ensure the flexibility and maintainability of the system, allowing the software of the RF receiving module to be updated remotely, enhancing system functions or repairing potential problems. After the OTA upgrade, all devices (electrical appliances) that could not be controlled by the self-powered device before can be controlled, that is, all old devices can be controlled.

[0103] In summary, the control of the electric device accessing the Bluetooth network in this application includes the transmission process and the reception process:

[0104] like Figure 7 As shown, the transmitting process is to press the switch of the self-powered device (driving component 1), generate electric energy, store energy, and the radio frequency transmitting module 52 is powered on to start and send a signal.

[0105] like Figure 8As shown, the receiving process is that the RF receiving module (RF module) receives the signal, confirms the valid signal, and the self-powered device drives the device to access the Bluetooth network.

[0106] For traditional self-powered wireless devices, the wireless receiving controller needs to have two protocols for the Sub-1GHz + 2.4GHz frequency bands, and the RF module is based on the Sub-1GHz chip combination, which requires more wireless receiving controllers, modules, and chips. This increases the complexity of the solution and increases the cost; therefore, the present application provides a system that directly accesses the Bluetooth network, that is, based on Bluetooth beacon technology. The specific RF transmission module 52 (kinetic switch) emits a Bluetooth 2.4G signal, including four elements: MAC (address), PID (user information), key (encrypted information) and key value. The RF receiving module (Bluetooth module) receives the signal - the processor (main controller) issues an instruction - controls the relay to access the Bluetooth network, which greatly improves the access efficiency and reduces the equipment cost and development cost. Because the relay directly accesses the Bluetooth network, no more wireless receiving controllers, modules, and chips are required. The firmware based on the mainstream 2.4GHz frequency band communication protocol can be directly included in the relevant equipment without any changes to the hardware. It can also enable millions, tens of millions or even hundreds of millions of devices to communicate directly with the self-powered wireless control system through OTA. This will undoubtedly make the self-powered wireless control system have more application scenarios and bring many benefits to consumers, society and the environment.

[0107] It should be noted that Beacon is a broadcast communication protocol based on the Bluetooth Low Energy protocol. A Beacon device is a low-power Bluetooth slave device that has this protocol. It is usually placed in a fixed position indoors and broadcasts a data packet to the surrounding area at regular intervals. When scanning as an independent Bluetooth host, it will receive the data packets broadcast by Beacon at intervals.

[0108] The relationship between the self-powered device and the RF receiving module based on Bluetooth Beacon technology is: Beacon is a broadcast communication protocol. When the driving component 1 of the self-powered device is pressed, the RF transmitting module 52 sends out a broadcast signal, which is received and identified and confirmed by the RF receiving module with Bluetooth support and processor, and is used to control electrical equipment or other equipment.

[0109] Based on the same inventive concept, the embodiment of the present application also provides a wireless control method based on a self-powered device using a wireless control system based on a self-powered device. The implementation solution provided by the method to solve the problem is similar to the implementation solution recorded in the above system, so the specific limitations in one or more embodiments of the wireless control method based on a self-powered device provided below can refer to the limitations of the wireless control system based on a self-powered device above, and will not be repeated here.

[0110] In an exemplary embodiment, a wireless control method based on a self-powered device is provided, comprising:

[0111] The processor sends a pairing instruction to the radio frequency receiving module and a clearing instruction to the radio frequency transmitting module 52 .

[0112] The signal instruction is received by the radio frequency receiving module; the signal instruction is a signal instruction transmitted by the radio frequency transmitting module 52 of the self-powered device.

[0113] Determine whether the signal instruction is a valid signal; the valid signal is that the signal instruction adopts the transceiver protocol of the radio frequency transmitting module 52, and the signal instruction includes an address, user information and a key; the address, the user information and the key are used to identify the self-powered device.

[0114] If the signal instruction is a valid signal, it is determined whether the signal instruction is a signal instruction recognized for the first time; if the signal instruction is a signal instruction recognized for the first time, the radio frequency receiving module stores the signal instruction; if the signal instruction is a signal instruction recognized again, the radio frequency receiving module controls the power-consuming device to access the Bluetooth network according to the signal instruction.

[0115] If the signal instruction is an invalid signal, the RF receiving module does not take any action.

[0116] The RF transmitting module 52 deletes the signal instruction stored in the RF transmitting module 52 based on the clear code instruction.

[0117] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The description of the above embodiments is only used to help understand the method and core ideas of this application. At the same time, for those skilled in the art, according to the ideas of this application, there will be changes in the specific implementation methods and application scope.
