The technical solution of the present invention will be described in detail below with specific examples. These particular embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Referring to fig. 1, a control system according to an embodiment of the present invention may include a self-generating switch 1 and a receiving terminal 2, where a self-generating switch and a receiving terminal are illustrated in the figure, in an actual control system, the number of the self-generating switches and the number of the receiving terminals may be multiple, and meanwhile, transmission of a wireless signal may be implemented between the self-generating switch 1 and the receiving terminal 2, where the wireless signal may be, for example, bluetooth, radio frequency, Wifi, or the like.

Meanwhile, the following description of the control event may also be understood with reference to the above.

In the embodiment of the present invention, referring to fig. 2, the self-generating switch 1 includes a processor 108, a memory 107, a key 101, a generator 103, a reset component 102, a rectifying module 111, an energy storage module 105, a voltage output module 106, and a wireless communication module 109.

The electrical connection referred to hereinafter may include a direct electrical connection and also include an indirect electrical connection.

The generator 103 is capable of generating electricity when the button 101 is manipulated (e.g., pressed and/or rebounded), and generating electric energy, which can be used to directly or indirectly power the processor 108, the wireless communication module 109, the memory 107, and the like, wherein the processor 108, the wireless communication module 109, and the memory 107 can be separated or integrated, and further, if integrated, then: the power supply to the processor 108, the wireless communication module 109 and the memory 107 can be realized based on the same power supply terminal.

The generator 103 may include a moving part 1031 and a sensing part 1032.

The moving part 1031 may be understood as a component or a combination of components that can be driven by at least one of a button and a reset component to move, and the sensing part 1032 may be understood as a component or a combination of components that can act on the moving part 1031 to sense and generate electric energy when the moving part moves, and any structure that can generate electric energy based on the movement in the art may be used as an alternative to the embodiment of the present invention.

In a specific example, the generator 103 may include a permanent magnet portion, a magnetic conductive portion, and a coil portion, the coil portion may be disposed on the magnetic conductive portion, and the coil portion may generate an induced voltage when the permanent magnet portion and the magnetic conductive portion move relative to each other. The coil part can be regarded as the above mentioned induction part 1032, and the permanent magnet part or the magnetic conducting part can be regarded as the above mentioned movement part 1031, that is: in some examples, the permanent magnet part moves to directly and indirectly transmit with the key and the reset component, and in other examples, the magnetic conduction part moves to directly and indirectly transmit with the key and the reset component. It can be seen that the sensing part 1032 may or may not move with the moving part 1031.

The wireless communication module 109 and the memory 107 are electrically connected to the processor 108, the sensing portion 1032 of the generator 103 is electrically connected to the energy storage module 105 through the rectifying module 111, the energy storage module 105 is electrically connected to the wireless communication module 109, the processor 108 and the memory 107 (for example, connected to the wireless communication module 109, the processor 108 and a power supply terminal of the memory 107) through the voltage output module 106, the reset component 102 (for example, a torsion spring, a tension spring, etc.) can be in transmission with the movement portion 1031 of the generator 103, and the key 101 can also be in transmission with the movement portion 1031 of the generator directly or indirectly.

In some embodiments, the reset component 102 can be directly driven to the moving portion 1031, or in other embodiments, the reset component 102 can also be driven to a button or other component, so as to be indirectly driven to the moving portion 1031.

Referring to fig. 11, the switch control method includes:

s301: whether the key is pressed down or not;

if so, step S302 may be performed: the reset component deforms and generates a reset acting force for overcoming the deformation, and a moving part of the generator is directly or indirectly driven by the key, so that the generator generates a first induction voltage;

if not, the process returns to step S301 to continue to determine whether the pressing operation has occurred.

In some embodiments, step S302 may be followed by: s303: the rectifying module stores first electric energy corresponding to the first induction voltage in the energy storage module.

Referring to fig. 11, the switch control method may also include:

s304: whether the key has rebounded control action or not;

if so, step S305 may be performed: the reset component drives a moving part of the generator under the action of the reset action force, so that the generator generates a second induction voltage;

in some embodiments, step S305 may be followed by: s306: and the rectifying module stores second electric energy corresponding to the second induction voltage in the energy storage module.

In a specific example, only the first electrical energy may be stored and/or used, and only the second electrical energy may be stored and/or used.

After step S303 and/or step S306, it may include:

s307: the energy storage module transmits the stored electric energy to the voltage output module, and the voltage output module provides required voltage for the processor, the memory and the wireless communication module by using the received electric energy to electrify the processor, the memory and the wireless communication module;

s308: after the processor, the memory and the wireless communication module are powered on, the processor generates and sends a corresponding current control message to a receiving end through the wireless communication module;

wherein the current control packet records current control information and the current verification identifier, so that: and the receiving terminal verifies whether the relationship between the current verification identification in the current control message and the stored historical verification identification is matched with a preset transformation rule of the current verification identification, and executes a control event corresponding to the current control information when the relationship is matched with the transformation rule, wherein the historical verification identification is determined according to the verification identification recorded in a control message or a pairing message sent to the receiving terminal before the self-generating switch.

The current steering information characterizes at least one of: the self-generating switch; the self-generating switch receives the operated key currently; and the self-generating switch performs the currently received control action on the key.

Before, after, or simultaneously with generating and sending the corresponding current control message to the receiving end through the wireless communication module (i.e. before, after, or simultaneously with implementing step S308), the processor may further include:

s309: in the continuously generated control actions of one press and one rebound, reading a current verification identifier from the memory and updating the current verification identifier for at least one control action;

wherein, updating the current verification identifier may specifically include: converting and updating the current verification identifier from the first numerical value to a second numerical value by using a preset conversion rule; the first value is different from the second value.

It can be seen that, since the pressing operation and the rebounding operation are in a pair and continuous manner, rebounding usually occurs after pressing. Furthermore, in the above solution, the current verification identifier may be updated only after the pressing manipulation action occurs, or the current verification identifier may be updated only after the rebounding manipulation action occurs, or both the current verification identifier and the current verification identifier may be updated after the pressing manipulation action and the rebounding manipulation action occur.

Referring to fig. 11, the processing method may further include:

s310: and writing the updated current verification identifier back to the memory before the electric energy stored by the energy storage module is exhausted.

Corresponding to the above steps S301 to S310, the functions of the respective components in the self-generating switch can be understood with reference to the following.

The reset device 102 is configured to: if the button 101 is pressed, then: deformation occurs and a reset acting force overcoming the deformation is generated; if the button 101 generates a rebounding operation, then: the moving part 1031 of the generator 103 is driven by the restoring force.

The generator 103 is configured to: if the button 101 is pressed, then: the moving part 1031 of the generator 103 is directly or indirectly driven by the key 101 to generate a first induced voltage in the induction part 1032 of the generator 103, and when the key 101 performs a rebounding operation, the moving part 1031 of the generator 103 is driven by the reset member 102 to generate a second induced voltage in the generator,

the rectification module 111 is configured to: storing first electric energy corresponding to the first induction voltage and/or second electric energy corresponding to the second induction voltage in the energy storage module;

the energy storage module 105 is configured to: transmitting the stored electrical energy to the voltage output module 106;

the voltage output module 106 is configured to: the received power (first power and/or second power) is used for providing required voltage for the processor 108, the memory 107 and the wireless communication module 109 to power up;

the processor 108 is configured to:

after the processor 108, the memory 107 and the wireless communication module 109 are powered on, generating and sending a corresponding current control message to the receiving end 2 through the wireless communication module 109;

in the continuously generated one-press operation and one-rebound operation, for at least one operation, before, after, or at the same time of generating and sending a current control message to a receiving end through the wireless communication module, a current verification identifier is read from the memory, the current verification identifier is updated (for example, the current verification identifier is updated from a first numerical value to a second numerical value by a preset conversion rule), and the updated current verification identifier is written back to the memory before the electric energy stored in the energy storage module is exhausted.

Wherein, if from the power generation switch be equipped with reset unit, then: the pressing operation can be the operation of pressing a key, and the rebounding operation can be the operation of removing the pressing action force so as to rebound the key.

In some examples, in a message (e.g., a current control message or a pairing message), at least two of information characterizing a self-generating switch, information characterizing a key, and information characterizing a manipulation action may be configured as one piece of information integrated together, for example, a predefined character string may be configured corresponding to each manipulation action of each key, so that the character string is used as (or represents) the current manipulation information, and further, by reading the character string, a receiving end may learn what manipulation action occurs on which key.

In other examples, corresponding characters or character strings may be respectively configured for the information characterizing the self-generating switch, the information characterizing the key, and the information characterizing the manipulation action as the current manipulation information.

The information characterizing the spontaneous electric switch may be information characterizing which spontaneous electric switch it is, or may be information characterizing which type of spontaneous electric switch it is (for example, at least one of the model, lot, brand, etc. of the spontaneous electric switch).

In a specific example, the current control information may include a switch identifier, and then the switch identifier may be used to represent the self-generating switch, and the current control information may further include a key value, and then the key value is used to represent a key currently received by the self-generating switch and a control action currently received by the key in the self-generating switch.

In addition, the current operation information can be understood as information that the receiving end can determine the control event according to the current operation information, and further, if the information (or information representing the key and the operation action) representing the self-generating switch is not used for determining the control event, then: even if the message is written in the information, the information may not be regarded as the current manipulation information.

The verification mark can be any character or combination of characters which can be suitable for realizing verification, the current verification mark can be understood as being currently sent by the self-generating switch, and the historical verification mark can be understood as being stored by a receiving end before the self-generating switch sends the current verification mark.

In some examples, the historical verification identifier may be a current verification identifier that is sent to the receiving end (sent with the control message or the pairing message) and stored by the receiving end when the self-power switch has performed the last operation, or determined according to the current verification identifier, and in other examples, the historical verification identifier may also be a current verification identifier that is sent to the receiving end (sent with the control message or the pairing message) and stored by the receiving end when the self-power switch has performed the last specific operation (for example, a pressed operation or a rebounded operation) or determined according to the current verification identifier.

Since the verification identifier is a specific numerical value, it may also be described as a serial number, and further, in the example of the embodiment of the present invention, the description of the serial number may be regarded as the description of the verification identifier.

The wireless communication module 109 may be any circuit module capable of implementing wireless communication, and for example, may include at least one of the following: radio frequency module, bluetooth module, Wifi module etc..

Corresponding to the above steps S301 to S310, and the corresponding functions of the components of the self-generating switch, the receiving end may be configured to:

receiving a current control message;

the current control message is sent by the self-generating switch through the switch control method or the self-generating switch;

verifying whether the relationship of the current verification identification and the stored historical verification identification matches the transformation rule;

and executing the control event corresponding to the current control information when the relation is matched with the transformation rule.

If the relationship does not match the transformation rule, the corresponding packet (e.g., the current control packet) may be discarded; the discarding of the current control packet may be understood as not processing based on the current control packet, for example: and the control event corresponding to the current control message is not executed, and the information such as the historical verification identifier and the like is not updated and changed based on the current control message.

In the above scheme, the current verification identifier is introduced in the interaction process of the self-generating switch and the receiving end, so that the matching verification of the current verification identifier and the historical verification identifier can be used as the basis for executing the control event, the control event of copying the message is avoided, and the effect of preventing copying attack is realized. Meanwhile, through the matching verification that whether the current verification identification and the historical verification identification are matched with the transformation rule or not, a basis can be provided for filtering repeated messages.

The verification identification in the real message is changed, and the verification identification in the copied message is usually repeated, so that the copied message can be effectively verified through verification based on the historical verification identification and the transformation rule (wherein the relation between the verification identification and the historical verification identification is usually not matched with the transformation rule), further, the control action of the copied message is avoided, and the safety is guaranteed.

In addition, when the historical verification identifier is the past current verification identifier, it can be ensured that: the identification verification sources are all derived from the self-generating switch, so that the verification accuracy and safety can be effectively guaranteed.

In one embodiment, referring to fig. 3 and 4, the self-generating switch 1 further includes a polarity identification module 110; the polarity identification module 110 electrically connects the generator 103 (e.g., the sensing portion 1032 thereof) and the processor 108.

Before the processor reads the current verification identifier from the memory and updates the current verification identifier, the method further includes:

after the processor, the memory and the wireless communication module are powered on, the processor identifies the currently occurring control action of the key through the polarity identification module and determines that the currently occurring control action is a target control action (that is, the processor 108 is further configured to identify the currently occurring control action of the key through the polarity identification module 110 and determine that the currently occurring control action is a target control action), and the target control action is a designated control action selected from a pressing control action and a rebounding control action.

It can be seen that in the above scheme, a scheme of "the transformation of the authentication identity occurs only after one complete press and rebound" is implemented.

Because there is a possibility of packet loss in wireless communication, if the data packet sent by pressing (i.e., the data packet of the control message sent after pressing) is lost, the data packet sent by rebounding (i.e., the data packet of the control message sent after rebounding) can be used as a remedy, and the receiving end can still perform a response action after receiving the rebounded data packet.

For this, the receiving end may determine whether to execute the control event by combining the verification identifier and the control action represented by the control packet, for example: the receiving end can judge according to the serial number (namely, the verification identification), and if the data packet is pressed (namely, the current control information is the pressing control information), certain response is carried out, so that a corresponding control event is executed; if the data packet is a rebound data packet (namely, the current control information is the rebound control information), the corresponding control event is executed only in response to the condition that the pressed data packet with the same sequence number (namely, the verification identifier) is not received before.

As can be seen, if the control events corresponding to the press and the rebound are the same, then: the scheme of 'the conversion of the verification identification only occurs after one complete press and rebound' can help to avoid the data packet loss from influencing the execution of the control event, and ensure that the corresponding control event can be executed effectively.

Meanwhile, after the receiving end is configured reasonably, it is also helpful to avoid the control message pointing to the same control event from being executed repeatedly, for example: when a lamp is controlled by a self-generating switch (i.e. the receiver is a lamp or a connected lamp), if the control event is: the lamp state is reversed, then: if both the press and the rebound will respond, the light is turned on when the press is made and then turned off after the rebound. The reasonable configuration can be, for example: if the self-generating switch changes the current verification identifier on time, then: the receiving end can update and write the current verification identification in the control message as a new historical verification identification when receiving the control message.

When the effects can be realized, even if the control events corresponding to press and rebound in some receiving ends are different, the realization of different control events can be ensured after the receiving ends are reasonably configured. The reasonable configuration can be, for example: if the self-generating switch changes the current verification identifier on time, then: the receiving end can write the verification identifier in the control message when receiving the rebounded control message as a new historical verification identifier.

Therefore, the same set of updating conditions of the verification identifier (namely, the current verification identifier is changed when the currently generated operation is the target operation and control action) is adopted, so that the requirements of pressing and rebounding the receiving end corresponding to the same control event can be met, and the requirements of pressing and rebounding the receiving end corresponding to different control events can also be met. Furthermore, the compatibility of the self-generating switch to various possible control requirements is effectively guaranteed, and the control diversity of the control system is improved.

In addition, the scheme of 'the change of the verification identifier only occurs after one complete press and rebound' can also play a role in saving electric energy. For example: if the sequence number is updated only at the time of the rebound (i.e. the current authentication identity), then: when the serial number is pressed down, the serial number (namely the current verification identifier) does not need to be updated, and particularly, the energy consumption for writing the updated serial number into a memory can be saved.

Moreover, when the sequence numbers (namely the current verification identifiers) corresponding to the pressed control actions and the rebounded control actions are the same, the receiving end can be simpler when the message is deduplicated according to the sequence numbers.

In a further example, the target manipulation motion is a rebound manipulation motion, and in other examples, the target manipulation motion may also be a press manipulation motion.

When a user presses a key of the self-generating switch, feedback of a control effect is generally expected to be immediately obtained. Furthermore, if the sequence number is updated only in the case of a rebound (i.e. the target actuation is a rebound actuation), all the power during the depression can be used for other tasks, in particular for transmitting signals, without the expenditure of power for updating the sequence number.

In one embodiment, please refer to fig. 3, the self-generating switch 1 further includes a key identification module 110, and the key identification module 110 is electrically connected to the processor;

referring to fig. 12, before the processor generates the current control packet, the method further includes:

s311: the processor reads a switch identification characterizing the self-generating switch from the memory;

s312: whether the current control action is a pressing control action or not;

if the determination result in step S312 is yes, step S313 may be implemented: the processor acquires current key information through the key identification module and updates the current key information in the memory;

if the determination result in step S312 is negative, step S314 may be implemented: whether the current control action is a rebounding control action or not;

if the determination result in step S314 is yes, step S315 may be implemented: the processor acquires the stored current key information from the memory;

if the determination result in step S314 is no, the process may return to step S312.

And based on the switch identification and the control action information, the current control information is determined based on the switch identification, the control action information and the acquired current key information.

Correspondingly, before generating the current control message, the processor 108 may be further configured to:

reading a switch identification characterizing the self-generating switch from the memory;

if the current operation is the operation of pressing down: acquiring current key information through the key identification module, and updating the current key information in the memory;

if the current operation is the springback operation, then: obtaining the stored current key information from the memory;

the current control information is determined based on the switch identifier, the currently generated control action, and the obtained current key information, for example, the switch identifier may be written into the current control packet, or a key value may be determined based on the control action and the current key information, and the key value may be written into the current control packet.

In a further example, referring to fig. 4, the key identification module 110 may include microswitches 1101, the number of the microswitches 1101 and the keys 101 may be one as shown in fig. 2, or may be multiple as shown in fig. 3 and 4, each of the microswitches 1101 and each of the keys 101 are in one-to-one correspondence, the microswitches 1101 may be activated when the corresponding key is pressed, and further feed back a signal to the processor 108, at this time, the processor 108 may read the fed back signal to determine key information representing the key, so as to learn which key the key currently pressed is.

In one embodiment, referring to fig. 4 and 6, the polarity identification module 112 includes a press identification portion 1121 and a rebound identification portion 1122; the press recognition unit 1121 electrically connects the sensing unit 1032 of the generator 103 and the processor 108, respectively, and the springback recognition unit 1122 electrically connects the sensing unit 1032 of the generator 103 and the processor 108, respectively.

The processor identifies the current operation action of the key through the polarity identification module, and the operation action comprises the following steps:

if the processor receives the designated signal sent by the press identification part, determining the currently generated control action as a press control action; wherein the press-down recognizing section transmits the designation signal to the processor only when the generator generates the first induced voltage;

and if the processor receives the designated signal sent by the springback recognition part, determining the current generated control action as a pressing control action, wherein the springback recognition part sends the designated signal to the processor only when the generator generates the second induced voltage.

Correspondingly, when the processor 108 identifies the current operation control action of the key through the polarity identification module, it is specifically configured to:

if receiving the designated signal sent by the pressing identification part 1121, determining the currently generated control action as the pressing control action; wherein the pressing identification portion 1121 transmits the designation signal to the processor 108 only when the generator 103 generates the first induced voltage;

when receiving the designation signal from the springback recognition unit 1122, the springback recognition unit 1122 determines the currently generated manipulation operation as a pressing manipulation operation, wherein the designation signal is transmitted to the processor 108 only when the generator 103 generates the second induced voltage.

The specific signal may be, for example, any one of the following: high level signal, high pulse signal, low level signal, low pulse signal.

The pulse signal generated by the sensing portion at the time of the next pressing and the pulse signal generated by the sensing portion at the time of the rebounding can be understood by referring to the waveforms shown in fig. 7. In fig. 7, the abscissa represents time, and the ordinate represents voltage.

For further example, referring to fig. 6, the pressing identification portion 1121 may include: pressing the identification first diode D21, pressing the identification second diode D22, pressing the identification first resistor R21, pressing the identification second resistor R22, and pressing the identification capacitor C21;

the positive electrode of the pressed identification first diode D21 is electrically connected to the first output terminal of the sensing portion, the negative electrode of the pressed identification first diode D21 is electrically connected to the first terminal of the pressed identification capacitor C21, the first terminal of the pressed identification first resistor R21 is pressed, the second terminal of the pressed identification capacitor C21 is grounded, the first terminal of the pressed identification second resistor R22 and the negative electrode of the pressed identification second diode D22 are electrically connected to the first receiving terminal (e.g., I/O port) of the processor 108, and the positive electrode of the pressed identification second diode D22 and the second terminal of the pressed identification second resistor R22 are grounded.

For further example, referring to fig. 6, the springback recognition unit 1122 may include: a rebound recognition first diode D23, a rebound recognition second diode D24, a rebound recognition first resistor R23, a rebound recognition second resistor R24, and a rebound recognition capacitor C22;

the positive electrode of the springback identification first diode D23 is electrically connected with the second output end of the sensing part, the negative electrode of the springback identification first diode D23 is electrically connected with the first end of the springback identification capacitor C22 and the first end of the springback identification first resistor R23, the second end of the springback identification capacitor C22 is grounded, the first end of the springback identification second resistor R24 and the negative electrode of the springback identification second diode D24 are electrically connected with the second receiving end (such as an I/O port) of the processor 108, the positive electrode of the springback identification second diode D24 and the second end of the springback identification second resistor R24 are grounded.

When the generator is pressed down or rebounded, the output end can respectively generate a positive pulse. The energy storage capacitor corresponding to the positive pulse (i.e. pressing the identification capacitor C21 or the rebound identification capacitor C22) is charged, and a positive pulse is output to the receiving end of the processor. And the capacitor of the negative pulse of the generator cannot be charged, and simultaneously, because of the existence of the diode, the electricity of the capacitor corresponding to the positive pulse cannot flow to the capacitor corresponding to the negative pulse, so that the capacitor corresponding to the negative pulse cannot output a pulse signal or a high-level signal to the processor. The processor can detect the level generated by the voltage division of the resistors so as to perform corresponding actions.

The press-down recognition diode D21 and the rebound recognition diode D23 may be isolated diodes, for example, the type RB551V diode may be used. The press-down recognition second diode D22 and the rebound recognition second diode D24 may be implemented as a zener diode, for example, a zener diode of 3.3V, and specifically, a zener diode of MMSZ5226BS may be selected, which has a maximum power consumption of 200mW and a reverse leakage current of 25 uA.

According to the selection of the resistance value of the divided voltage, the maximum voltage of the generator needs to reach 3.5 × 5/2 × 8.75V to reach the maximum withstand voltage of the IO port of 3.5V, and the generator can usually meet the requirement.

In the embodiment of the present invention, only the pressing identification portion may be adopted, or only the rebounding identification portion may be adopted, for example, if the time for transmitting the message from the power switch is short, and the message is sent out and the power is consumed soon after each pressing, the switch may only need one identification portion (for example, the pressing identification portion or the rebounding identification portion). Such as: when only one pressing identification part is pressed, the switch generates a high level when being pressed, and the processor identifies that the pressing is performed. When the switch rebounds, the processor does not detect the high level, which may also be referred to as a rebound.

However, for a part of the self-generating switches (for example, the self-generating switch of the bluetooth module is used as the wireless communication module), because each transmission duration is long, when the user releases the switch, the pressed message is not yet transmitted, and at this time, the processor is still in a working state, and if no rebound recognition part outputs a high level, the processor cannot know that the switch rebounds. Therefore, two independent identification parts are required to identify the press-down and the rebound, so that when the processor detects that the corresponding IO port has a high level or a positive pulse, the corresponding press-down or rebound is considered to have occurred. Therefore, in the scheme, the IO port identified by the polarity can be detected not only at the power-on moment but also at the rebound moment to judge whether the IO port is pressed down.

In one embodiment, referring to fig. 4, the memory 107 includes a first memory 1071 and a second memory 1072, the current authentication identifier update is stored in the first memory 1071; the first memory 1071 and the second memory 1072 storing programs are different memories, and the first memory 1071 is a memory which does not lose data after power failure.

The current verification identifier updated and stored in the first memory 1071 is the same as the current verification identifier recorded in the current manipulation message.

In a further embodiment, the first memory 1071 is a memory capable of erasing, writing, and reading data in units of one or more bytes, wherein the writing and reading time of a single byte does not exceed 10ms, and the consumed energy does not exceed 300 uJ. The first memory 1071 includes, for example, a Flash memory and/or a ferroelectric memory.

In addition, the first memory also stores current key information, and the current key information represents the key which is pressed by the self-generating switch for the last time; and the key represented by the current key information is the same as the key represented by the current control information.

The first memory 1071 may not select the conventional FLASH, because the conventional false sh must be erased (written) in units of sectors, which causes too much power to be written and the generator may not be able to support it. On the contrary, when the memories such as the EEPROM, the ferroelectric memory and the like are selected, the situation that the electric quantity of the generator is difficult to support can be effectively avoided.

In a specific example, the first memory 1071 may be coupled to the processor through an IIC bus using 24C 02. Taking fig. 8 as an example, the power supply (VDD-EE) of the first memory 1071 is isolated from the processor's power supply VDD by diode D71 so that the processor 108 is in an unpowered state when necessary, such as when burning data into an EEPROM during a production phase, so that the IIC communication between the EEPROM and the burning tool is not affected by the IIC pin of the processing unit.

Wherein, for storing in particular: (1) a current authentication identity; (2) current key press information.

When the switch is pressed down during working, the verification identifier can be read from the first memory, then updating (such as self-increasing operation) is carried out, the updated current verification identifier is filled in a message to be sent, then the self-updated current verification identifier is written back to the first memory again, then the electric quantity is exhausted, and the processor and the memory are powered off and halted.

The switch sends current key information (representing which key is pressed and released) when being pressed and/or rebounded, but due to the structural limitation of the self-generating switch, although the generator generates electricity when the switch is released, the micro switch for detecting key positions is already released, and which key is pressed to act cannot be identified, so that a first memory (namely two memories are adopted) is arranged, and the current key information at the moment is written into the first memory when the switch is pressed; during rebound, although the current key information cannot be read from the state of the microswitch, the previous key information can be read from the first memory as the current key information, so that the message during rebound also carries a key value, thereby doubling the probability that a receiving end can receive the message and improving the reliability.

In addition, the SCL terminal of the first memory 1071 may be connected to the VDD-EE of the processor via a resistor R72, and the SDA terminal of the first memory 1071 may be connected to the VDD-EE of the processor via a resistor R71.

In one embodiment, referring to fig. 4 and fig. 5, the rectifying module 111 includes a first rectifying portion 1111 and a second rectifying portion 1112; the first rectifying part 1111 is electrically connected to the induction part 1032 of the generator 103 and the energy storage module 105, and the second rectifying part 1112 is electrically connected to the induction part 1032 of the generator 103 and the energy storage module 105.

The rectifier module stores first electric energy corresponding to the first induction voltage and second electric energy corresponding to the second induction voltage in the energy storage module, and the rectifier module comprises:

the first rectifying part rectifies the first induction voltage and stores corresponding first electric energy in the energy storage module;

the second rectifying part rectifies the second induction voltage and stores corresponding second electric energy in the energy storage module.

Correspondingly, the rectifying module 111 is used for storing the first electric energy corresponding to the first induced voltage and the second electric energy corresponding to the second induced voltage in the energy storage module, and is specifically configured to:

the first rectifying part 1111 rectifies the first induced voltage and stores corresponding first electric energy in the energy storage module;

the second rectifying unit 1112 rectifies the second induced voltage and stores corresponding second electric energy in the energy storage module.

For further example, referring to fig. 5, the first rectifying unit 1111 includes a first rectifying diode D11, a second rectifying diode D12 and a first rectifying resistor R11, and the second rectifying unit 1112 includes a third rectifying diode D13, a fourth rectifying diode D14 and a first rectifying resistor R12.

The cathode of the first rectifying diode D11 and the cathode of the second rectifying diode D12 can be respectively and electrically connected to the first output end and the second output end of the induction part, the anode of the first rectifying diode D11 and the anode of the second rectifying diode D12 can be grounded, and can be connected to the first end of the first rectifying resistor R11, and the second end of the first rectifying resistor R11 is connected to the second output end;

the anode of the third rectifying diode D13 and the anode of the fourth rectifying diode D14 can be respectively electrically connected to the first output terminal and the second output terminal of the sensing portion, the cathode of the third rectifying diode D13 and the cathode of the fourth rectifying diode D14 can be grounded, and can be connected to the first terminal of the second rectifying resistor R12, and the second terminal of the second rectifying resistor R12 is connected to the first output terminal.

In the above scheme, the third rectifier diode D13 and the fourth rectifier diode D14 constitute a positive pulse rectifier, and the first rectifier diode D11 and the second rectifier diode D12 constitute a negative pulse rectifier. Therefore, when the generator is pressed down and reset, the electric energy can be transmitted to the energy storage module 105 through the rectifying device, and signals can be sent when the wireless switch is pressed down and reset.

In one embodiment, the voltage output module 106 may include: the controller 1061, the energy storage capacitor C61 and the freewheeling unit (for example, including the freewheeling inductor L61);

the input side of the controller 1061 is electrically connected to the energy storage module, meanwhile, the enable end of the controller 1061 may be connected to the energy storage module and a first end of a capacitor C62, a second end of the capacitor C62 may be grounded, the output side of the controller 1061 is electrically connected to a first end of the freewheeling unit (e.g., a freewheeling inductor L61), a second end of the freewheeling unit (e.g., a freewheeling inductor L61) is electrically connected to at least one of the processor and the wireless communication module memory directly or indirectly, and the energy storage capacitor C61 is electrically connected between the second end of the freewheeling unit (e.g., a freewheeling inductor L61) and ground; the controller 1061 is configured to control on and off between an input side and an output side thereof, and adjust a voltage output through the freewheel unit and the energy storage capacitor by adjusting a switching frequency of the on and off and a time period of the on or off.

The voltage output module 106 may further include a first feedback resistor R61 and a second feedback resistor R62 for detecting the output voltage and feeding the output voltage back to the controller 1061.

The controller 1061 may be integrated with a PWM generating unit, which adjusts the width or frequency of the output pulse according to the feedback voltage, controls an internal or external switching tube, and intermittently charges the output inductor to achieve the purpose of voltage stabilization.

In some examples, a resistor R63 may be disposed between the output terminal of the energy storage module and the output terminal of the voltage output module (i.e., the VDD terminal and the VIN terminal), and a capacitor C63 and a zener diode D61 may be disposed between the VIN terminal and ground in parallel.

In one embodiment, the transformation rule includes at least one of:

accumulating a first reference value on the basis of said first value to obtain said second value;

subtracting a second reference value from the first value to obtain a second value;

multiplying a third reference value by the first value to obtain the second value;

dividing the first value by a fourth reference value to obtain the second value.

The accumulation, subtraction, multiplication, division and the like can be calculated by adopting decimal calculation and can also be calculated by adopting binary system or other binary systems. The first, second, third and fourth reference values may be fixed values or variable values, and their signs are usually the same and are not zero, e.g. positive numbers.

Taking the accumulated first reference value as an example, the first reference value used for accumulation may be a positive number that varies within a certain range, and further for example, the accumulated value may vary regularly, for example: if the cycle changes from accumulation 1, accumulation 2, and accumulation 3, then: the k-th transformation is realized by accumulating 1, the k + 1-th transformation is realized by accumulating 2, the k + 2-th transformation is realized by accumulating 3, and the k + 3-th transformation is realized by accumulating 1 again.

Corresponding to the above various cases, there are:

if the transformation rule is: accumulating a first reference value on the basis of said first value to obtain said second value, then: when the receiving end verifies whether the current verification identification is matched with the historical verification identification, the receiving end can verify whether the current verification identification is larger than the historical verification identification, or: verifying whether the current verification identifier is larger than the historical verification identifier or not, wherein the difference value of the current verification identifier and the historical verification identifier is matched with the first reference value;

if the transformation rule is: subtracting a second reference value from the first value to obtain a second value; then: when the receiving end verifies whether the current verification identification is matched with the historical verification identification, the receiving end can verify whether the current verification identification is smaller than the historical verification identification, or: verifying whether the current verification identifier is smaller than the historical verification identifier, and the difference between the current verification identifier and the historical verification identifier is matched with the second reference value;

if the transformation rule is: multiplying a third reference value by the first value to obtain the second value; then: when the receiving end verifies whether the current verification identification is matched with the historical verification identification, the receiving end can verify whether the current verification identification is larger than the historical verification identification, or: verifying whether the current verification identifier is larger than the historical verification identifier, wherein the ratio of the current verification identifier to the historical verification identifier is matched with the third reference value;

if the transformation rule is: dividing said first value by a fourth reference value to obtain said second value; then: when the receiving end verifies whether the current verification identification is matched with the historical verification identification, the receiving end can verify whether the current verification identification is smaller than the historical verification identification, or: and verifying whether the current verification identification is smaller than the historical verification identification or not, wherein the ratio of the current verification identification to the historical verification identification is matched with the fourth reference value.

In the above scheme, by comparing the difference value with the first numerical value and the second numerical value and comparing the ratio value with the third numerical value and the fourth numerical value, it can be verified whether the comparison between the current verification identifier and the historical verification identifier is larger or smaller, and the amplitude of the change can be verified, so that an attacker can perform exhaustive attack by using the numerical value larger (or smaller) than the current numerical value, and the security is further improved.

The difference value is matched with the first reference value and the second reference value, which can be understood as the same value, or the difference value is smaller than a certain threshold value, and the ratio value is matched with the third reference value and the fourth reference value, which can be understood as the same value, or the difference value is smaller than a certain threshold value.

Referring to fig. 13, in an example, the self-generating switch carries a serial number (i.e., a verification flag), the serial number increases (or decreases) by itself each time the switch is pressed, and the serial number increases by itself only once after a complete press + rebound operation; the representation carried in the message is information of pressing/bouncing (it can be understood that the control information can represent the control action).

Specifically, the self-generating switch rebounds after being pressed down each time, and the generator operates to generate electricity when being pressed down and rebounded, so that power is supplied to a back-end circuit (such as a processor, a wireless communication module, a memory and the like). The back-end circuit can identify whether the control action is pressing or rebounding through the polarity identification module.

If it is a push manipulation, the serial number (i.e. the stored authentication identifier) is read from the memory, then the serial number is incremented (which may be understood as the transformation), then the key information is read, and a control message is generated (which may correspond to step S308). Then, the serial number and the key information are written back to the memory, and can be used for reading during the rebound, and then the message is sent (which may correspond to steps S310 and S313). The order of writing back the memory and sending the message can be interchanged.

If the control is the rebound control, the serial number is directly read from the memory without self-increment (namely, the conversion is not needed to be implemented), and the key information is also directly read from the memory (rather than reading the feedback signal of the microswitch).

In one embodiment, the current control packet further includes signature information, where the signature information is calculated based on a first key and changes with a change of the current verification identifier;

the signature information can be verified by the receiving end through a second key, and the first key is matched with the second key.

The key can be fixed and unchangeable, and can also be refreshed and changed by a certain method, and the self-generating switch and the receiving terminal are resynchronized after the refreshing and changing. For example: the key may vary based on a function value with time as an argument, the functional relationship corresponding to the first key being adapted to the functional relationship corresponding to the second key.

In a specific example, the key may be a secret string of data, wherein the signature information may be calculated by a predetermined algorithm (e.g., AES algorithm) after combining the plaintext and the key. The plaintext may, for example, control at least part of the content of the message, which may contain the authentication identifier but no signature.

For example: in the self-generating switch, the processor can encrypt the contents of the fields except the signature field in the payload part of the current control message to be sent by using the first secret key to obtain signature information, the receiving end can encrypt the contents of the fields except the signature field in the payload part of the received current control message by using the second secret key to obtain the signature information, and the receiving end can verify the signature information recorded in the current control message by using the calculated signature information.

In addition, the first key and the second key may be the same, and in other examples, the two keys may also be different.

The anti-counterfeiting function can be realized through the signature information, and the safety is guaranteed.

To facilitate the description of the role of signature information and authentication indicia (e.g., serial number), several concepts are first cleared as follows:

copy attack:

it can be understood that: an attacker first captures a message of a legal switch and then sends the message out without any change. By verifying the use of the identification, it is possible to effectively protect against copying attacks, such as: the receiving end stores the serial number (i.e. the verification identifier) of the last received message, and after receiving a new message, the receiving end continues to check the serial number even if the verification signature information is legal: the disallowed sequence number is the sequence number that has been received before the press or bounce, but is a sequence number that is larger than before and falls within a window (all, or a sliding window that is large enough).

Forgery attack:

it can be understood that: the attacker can operate a real device (e.g., an autonomous switch) that can issue a control message and then actively add 1 to the serial number (if the serial number is plaintext) to reconstruct the message.

Through the signature information, forgery attacks can be effectively prevented, and the signature information is calculated by the key according to the previous message content (if the serial number is plaintext). The self-generating switch is encrypted by a key, the receiving end calculates once by the key, and if the key is obtained, the message of the transmitting end is considered to be legal.

When using the authentication identification (e.g., serial number) and signature information, it may be possible, for example:

in the pairing process, the receiving end and the self-generating switch synchronize serial numbers; the sequence number is not verified in the pairing process, and the signature information can be selected to be verified still, namely the pairing process only considers forgery prevention and does not consider copy prevention. Of course, the signature information can be verified;

during normal operation, on one hand, signature information is verified, and on the other hand, the serial number is verified, and only the verification result is allowed to be larger (or smaller) than the previous serial number. If further stringent verification is required, the sequence number is required to be larger than the previous sequence number and to fall within a window (which may be embodied, for example, as the first, second, third, fourth reference values mentioned above). Window-based verification may have an effect on exhaustive attacks, such as: an attacker can perform an exhaustive attack with a sequence number that is larger than the current sequence number if no window is required.

In one embodiment, the authentication identifier (e.g., sequence number) itself is also converted before transmission, and an attacker cannot obtain the current sequence number. And further: the current verification identifier recorded in the current control message is a converted current verification identifier, wherein the conversion mode is a first data conversion mode, namely: the current verification identifier recorded in the current control message is the current verification identifier converted by the first data conversion mode;

the current verification identifier verified by the receiving end is obtained by reversely converting the converted current verification identifier, wherein the reverse conversion mode is a second data conversion mode, and the first data conversion mode and the second data conversion mode are opposite data conversion modes, that is: the current verification mark verified by the receiving end is obtained by carrying out reverse conversion on the converted current verification mark in a second data conversion mode.

The first data conversion method and the second data conversion method are opposite conversion methods, and no matter which conversion method is adopted, the scope of the embodiment of the invention is not deviated.

In a specific example, referring to fig. 17, the receiving end may check the duplicate according to the "ID-serial number"; where the ID is understood to be the device-manufacturer ID (corresponding to the device-manufacturer ID in fig. 15 and 16), the serial number of the message is stored after the message is received for the specific ID. After receiving the message with the same ID next time, comparing the serial number (namely the current verification identifier) with the previous one, and if the serial number is the same as the historical value (namely the historical verification identifier), considering that the message is a repeated message and discarding the repeated message; if the message is newer than the historical value, the message is considered as a new message, and subsequent processing is carried out.

Specifically, after receiving the message, the basic message validity judgment is firstly made according to the message format. Then, extracting the serial number; comparing the serial number with the historical value (i.e. comparing the current verification identifier with the past verification identifier for verification); if the sequence number is larger than the historical value, executing corresponding control action (namely control event), and writing a new sequence number into the historical value for standby; if not, then the duplicate sequence number is considered and discarded.

In one embodiment, the current control packet is sent from the power generation switch through bluetooth, and the wireless communication module is a bluetooth module, and a packet sending and data packet scanning and receiving manner in bluetooth communication will be described below.

In a specific example, the receiving end itself may be awakened and dormant according to the wakeup sleep cycle, and the wakeup sleep cycle includes an alternate wakeup time interval and a sleep time interval, that is: and the receiving end enters the dormancy period after the wakeup period, the dormancy period enters the wakeup period after the dormancy period, the cycle is repeated, and the receiving end receives the data packet only in the wakeup period.

In fig. 14, the waveform of the receiving scan is a schematic waveform of the receiving scan data packet at the receiving end, wherein the wakeup period can be characterized as Ton, the sleep period can be characterized as Toff, and the waveform of the sending packet is a schematic waveform of the sending data packet from the power switch, wherein the convex waveform is a sending period that can be regarded as one data packet.

In step S308, sending the corresponding current control packet to the receiving end through the wireless communication module specifically includes:

broadcast N group data packet outwards in proper order through the bluetooth to make: the receiving end captures at least one data packet in an awakening time period, wherein each group of data packets comprises a plurality of data packets, and each data packet comprises the current control message; and the broadcast interval of the adjacent data packets in the N groups of data packets is matched with the awakening sleep period of the receiving end, wherein N is more than or equal to 2.

Correspondingly, when the processor sends the corresponding current control message to the receiving end through the wireless communication module, the processor is specifically configured to:

Correspondingly, the receiving end may specifically be configured to:

capturing at least one data packet in N groups of data packets sent by the self-generating switch in the awakening period through Bluetooth, wherein the N groups of data packets are broadcast to the outside sequentially through the Bluetooth by the self-generating switch, and each data packet contains the current control message; the total broadcast duration of the N groups of data packets and the broadcast interval of two adjacent data packets are matched with the awakening sleep period of the receiving end, wherein N is more than or equal to 2.

Wherein a broadcast interval is understood to be: the interval between the broadcast start times of two adjacent groups of data packets can also be regarded as the broadcast period of each group of data packets, and each broadcast period only sends one group of data packets.

The duration of the awakening time interval is greater than or equal to the broadcasting interval of two adjacent data packets;

the duration of the sleep period is less than or equal to N-1 times the broadcast interval.

Through the scheme, the data packet can be received by the receiving end in the awakening time period no matter when the data packet is sent out by the self-generating switch in the data packet receiving and sending process.

In the case that the wake-up period Ton is within the large transmission period, there should be at least 1 packet in the window of the wake-up period Ton, i.e. the wake-up periods Ton cannot all fall within the broadcast interval (e.g. 20mS), and the wake-up period Ton is greater than or equal to the broadcast interval (e.g. 20 mS).

At the same time, it is ensured that at least one packet falls outside the window of the sleep period Toff, which is guaranteed to be less than or equal to the broadcast interval (N-1), for example less than or equal to 20mS (N-1), taking into account the time duration (for example 1mS) for which the packet itself is to be used.

In a specific example, the specified packet sending interval duration (i.e. the formed broadcast interval) may be selected to be 20 mS;

the wake-up sleep cycle of the receiving end can be 100 mS;

the duty cycle may be 20%,

correspondingly, the wake-up period Ton is 20mS and the sleep period Toff is 80 mS.

Under the above parameters, if the autonomous switch can send 5 groups of data packets, the receiving end can scan at least 1 group of data packets. If the transmitting end can send 10 groups of data packets, the receiving end can scan at least 2 groups of data packets.

In another specific example, if N is 5, the awake period Ton may be specifically 25mS, the sleep period Toff may be specifically 75mS, and further, the corresponding duty ratio is 25%, and the receiving end may scan at least 1 group of data packets and leave a certain margin.

In another specific example, the awake sleep cycle may be 125mS, the awake period Ton may be 25mS, and the sleep period may be 100mS, correspondingly, if the packet sending interval is 20mS, then: 20mS (N-1) is greater than or equal to 100mS, and N is greater than or equal to 6 (namely, at least 6 groups of data packets need to be sent), wherein when N is 6, at least one group of data packets is scanned in the awakening period.

In a further example, the plurality of data packets in the same group are transmitted via at least two of the following channels:

2.402GHz；2.428GHz；2.480GHz。

wherein, the treater passes through bluetooth module is external broadcast N group data packet in proper order specifically includes:

the processor counts the time of the broadcast interval after starting to send a group of data packets, and sends out another group of corresponding data packets when the counted time reaches the specified packet sending interval time length;

correspondingly, when the processor 108 sequentially broadcasts the N groups of packets to the outside through the bluetooth module, the processor is specifically configured to:

after a group of data packets are started to be sent, the time of the broadcast interval is timed, and when the time reaches the specified time length of the packet sending interval, another group of corresponding data packets are sent out.

The above timing function can be realized by adopting a timing module integrated in the processor.

In a specific example, the signals transmitted by the wireless communication module are bluetooth signals, for example, 2.4GHZ can be used as a carrier frequency, and the data packets are transmitted through a designated bluetooth channel. Specifically, the self-generating bluetooth switch transmits data in 40 2-MHz channels using bluetooth low energy technology. Preferably, the data is transmitted in a broadcast channel. The frequency points of the three broadcast frequency channels are respectively: the 37 channel is 2.402 GHz; the 38 channel is 2.428 GHz; the 39 channel is 2.480 GHz.

Wherein more than one packet of signals will be sent per press, e.g. 3-10 packets of data may be sent. The processor may be integrated with the above mentioned timing module, and the timing module is used for delaying in the transmission interval.

In one example, the packet interval duration may be 20mS, and may specifically fluctuate randomly within a range of 20mS ± 5mS (i.e., the specified packet interval duration may be in an interval range of 15 mS to 25 mS), so as to reduce the probability that transmitted packets of different switches collide over the air.

the payload part further includes a Frame Header control field (corresponding to "Frame Header" shown in the figure) including:

a switch identification indication field (corresponding to "ID type" shown in the figure) for describing with 1 bit whether or not the payload section describes the switch; for example: taking fig. 15 as an example, if the field is 0, it indicates that the payload portion does not additionally include Source ID (i.e., switch ID); taking fig. 16 as an example, if the field is 1, it indicates that the payload portion additionally includes a Source ID (i.e., a switch identifier) of 4 bytes, and the above design can be used to solve the problem that the upper layer application of the iOS device cannot obtain the MAC of the packet.

The payload section further includes:

The following will specifically exemplify a procedure for executing a control event by the receiving end.

In one embodiment, the receiving end may be a wall switch, and the control event includes at least one of the following:

the wall switch is turned off;

the wall switch is turned on;

turning off a designated function of the wall switch;

turning on a designated function of the wall switch;

and sending out a specified signal to the outside.

For other receivers that function similarly to wall switches, the control event can be understood with reference to the above example.

Regardless of the receiving end, the control event may include at least one of the following:

switching the on-off state of the receiving end, wherein the on-off state refers to that the receiving end is opened or closed;

and changing the working parameters of the receiving end.

In one embodiment, the process of executing the control event may be, for example:

detecting whether predefined state switching operation and parameter change operation occur or not according to the current operation information, or: detecting whether the state switching operation and the parameter change operation occur according to the current operation information and the previously received operation information;

if the state switching operation occurs, switching the on-off state of the receiving end;

if the parameter change operation occurs, changing the working parameters of the receiving end;

the state switching manipulation is distinct from the parameter change manipulation.

In a further example, the state switching operation is: the pressing time of the corresponding key is longer than the specified time, and the parameter change control is as follows: the pressing duration of the corresponding key is longer than the designated duration. In other examples, the state switching operation may also be: the pressing duration of the corresponding key is longer than the specified duration, and the parameter change control is as follows: the pressing time length of the corresponding key is shorter than the designated time length.

In the above scheme, if the receiver is a lamp, then: in one example, for a key press, a short press (released immediately after pressing) may implement a basic ON/OFF toggle command, such as turning the light ON and OFF, and a long press may implement dimming (e.g., adjusting the brightness of the light).

if the current control information is the control information starting to change, starting to change the working parameters of the receiving end;

if the current control information is control information which stops changing, the working parameters of the receiving end are stopped changing;

the start change control information and the stop change control information represent different keys and/or different control actions.

In a further example, the start change manipulation information represents a manipulation action of a corresponding key being pressed; the stop change control information represents the control action corresponding to the rebounding of the key. In other examples, the start change manipulation information and the stop change manipulation information may represent manipulation actions of different keys, or may represent manipulation actions of pressing different times.

In one embodiment, for the same key of the same switch, if the corresponding pressing control information and the corresponding rebounding control information correspond to different control events, then:

the historical verification identification stored in the receiving end is determined according to the verification identification recorded in the control message generated by the appointed control action; the appointed control action is used as the control action of pressing down the key or the control action of rebounding the key. For example: the receiving end may only store the current verification identifier therein as the historical verification identifier when receiving the control packet generated by the pressing operation, for example: the receiving end can only store the current verification identifier as the historical verification identifier when receiving the control message generated by the rebounded control action.

The receiving end of the above adjustable operating parameter may be, for example, any one of the following: lamps, fans, automatic curtains. But not limited to this, any receiving end having the requirement of adjusting the working parameters can be used as an optional scheme.

Referring to fig. 18, if the receiving end is a lamp, an example of a scheme for dimming the lamp is as follows: wherein mainly realized starting to adjust luminance when pressing the button, stopped adjusting luminance when kick-backing. At this time, the sequence number can be used for duplication checking of multi-packet data transmitted at the time of pressing and rebounding.

Specifically, after receiving the control message, first making a basic message validity judgment according to the message format, and then extracting the serial number therein; comparing the serial number with the historical value (i.e. comparing the current verification identifier with the historical verification identifier for verification); if not, the repeated sequence number is considered and discarded. If the current value is greater than the historical value and the message is a message for pressing the control, dimming is started; if the current value is greater than the historical value and is a message for rebounding control, dimming is stopped; and a new serial number is written into the history value for standby. This process may correspond to the processing procedure described above for the start change handling information, the stop change handling information.

In another example, for the same key, a short press (immediately released after pressing) implements a basic ON/OFF toggle command, and a long press implements dimming. This process may correspond to the process described above for the state switching manipulation information and the parameter change manipulation information.
