According to the selection of the resistance value of the voltage divider, the maximum voltage of the generator needs to reach U=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 this requirement.

In the embodiment of the present invention, only the push-down identification part can be used, and only the rebound identification part can be used. For example, if the time for the self-generating wireless switch to transmit a message is very short, the transmission will be completed soon after each press. When the power is exhausted, the switch may only need one recognition part (for example, a push-down recognition part or a rebound recognition part). For example: when there is only one push-down identification part, a high level is generated when the switch is pressed down, and the processor recognizes that it is a press-down. When the switch rebounds, the processor cannot detect the high level, which can also be considered as a rebound at this time.

However, for some self-generating wireless switches (such as self-generating wireless switches with Bluetooth modules in the wireless communication module), due to the long duration of each transmission, it is possible that when the user releases the switch, the pressed message has not yet been sent. At this moment, the processor is still in the working state. If there is no rebound identification part to output a high level, the processor has no way of knowing that the switch has rebounded. Therefore, two independent identification parts are needed to identify the pressing and rebounding, so that the processor detects that the corresponding IO port has a high level or a positive pulse, and then it is considered that the corresponding pressing or rebounding has occurred. It can be seen that in this scheme, it is not only possible to detect the IO port of polarity recognition at the moment of "power on" to judge whether it is a push-down or a rebound.

In one of the implementation manners, please refer to FIG. 5 , the memory 107 includes a first memory 1071 for storing programs, and a second memory 1072 for storing current key information and/or current verification identification, the current The verification identification is used as the verification basis for the message sent by the self-generating wireless switch; the current verification identification is updated and stored in the second memory 1072; the second memory 1072 and the first memory 1071 storing programs It is a different memory, and the second memory 1072 is a memory that does not lose data after power failure.

Wherein, the current verification ID updated and stored in the second memory 1072 is the same as the current verification ID recorded in the current control message.

In a further solution, the second memory 1072 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 10 ms, The energy consumed does not exceed 300uJ. For example, the second memory 1072 includes Flash memory and/or ferroelectric memory.

In addition, the second memory 1072 also stores current key information, and the current key information represents the key that was pressed last time on the self-generating wireless switch.

Wherein, the second memory 1072 may not select conventional FLASH, this is because conventional FALSH must be erased (written) in units of sectors, resulting in too much power required for writing, and the generator may not be able to support . On the contrary, when selecting memory such as EEPROM, ferroelectric memory, etc., it can effectively avoid the situation that the power of the generator is difficult to support.

In a specific example, the second memory 1072 may use a 24C02 and be connected to the processor through an IIC bus. Taking FIG. 8 as an example, the power supply (VDD-EE) of the second memory 1072 is isolated from the power supply VDD of the processor through the diode D71, so that when necessary, such as when burning data into the EEPROM in the production stage, the processor 108 is In the unpowered state, the IIC communication between the EEPROM and the programming tool is not affected by the IIC pin of the processing unit.

Among them, it is specially used for storing: (1) current verification identification; (2) current key information.

When working, when the switch is pressed, the verification identification can be read from the second memory first, and then updated (such as self-increment operation), the updated current verification identification is filled in the message and sent, and then the self-updated The current verification identification of the device is rewritten back to the second memory, after which the power will be exhausted, and both the processor and the memory will "power down" and crash.

When the switch is pressed and/or rebounded, it will send the current button information (representing which button is pressed & released), but due to the structural limitation of the self-generating wireless switch, although the generator will generate electricity when the switch is released, it will be used Since the micro switch for detecting the key position has been released, it is impossible to identify which key is acting. Therefore, two memories are used. When the switch is pressed, the current key information at this time is written into the second memory; When flipping, although the current key information cannot be read from the state of the micro switch, the previous key information can be read from the second memory as the current key information, so that the message when rebounding also carries the key value. As a result, the probability that the controlled device can receive the message is doubled, and the reliability is improved.

In addition, please refer to FIG. 9 , the SCL terminal of the second memory 1072 can be connected to the VDD-EE of the processor through the resistor R72, and the SDA terminal of the second memory 1072 can be connected to the VDD-EE of the processor through the resistor R71.

Regarding the processing of the current verification identifier, when the processor sends the current control message (for example, the first control information) to the controlled device, it may cause the controlled device to verify the current Whether the relationship between the verification identifier and the stored historical verification identifier matches the preset conversion rule of the current verification identifier, and when the relationship matches the conversion rule, execute the control event corresponding to the current control message, so The historical verification identifier is determined according to the verification identifier recorded in the control message (for example, first control information) previously sent by the self-generating wireless switch to the controlled device.

The current control message represents at least one of the following: the self-generating wireless switch; the key currently controlled by the self-generating wireless switch; the control action currently received by the key in the self-generating wireless switch.

Before, after or at the same time as generating and sending the corresponding current control message to the controlled device through the wireless communication module, the processor may further include:

During a press-down manipulation action and a rebound manipulation action that occur continuously, for at least one of the manipulation actions, the current verification identification is read from the memory, and the current verification identification is changed from the first The numerical transformation is updated to a second numerical value;

Wherein, the first numerical value is different from the second numerical value.

It can be seen that since the control action of pressing down and the control action of rebounding are paired and continuous, furthermore, after pressing down, rebounding will usually inevitably occur. Furthermore, in the above solution, the current verification mark can be updated only after the manipulation action of pressing occurs, or the current verification mark can be updated only after the manipulation action of rebound occurs, or can be updated after the manipulation action of pressing The current verification mark is updated after the rebound manipulation action.

In addition, the processor may also write the updated current verification identifier back to the memory before the energy stored in the energy storage module is exhausted.

In one push-down manipulation action and one rebound manipulation action that occur continuously, for at least one of the manipulation actions, before and after the current control message is generated and sent to the controlled device through the first wireless communication module Or at the same time, read the current verification identification from the memory, and update the current verification identification from the first value to the second value according to the preset conversion rule, and before the electric energy stored in the energy storage module is exhausted, Writing the updated current verification identifier back to the memory, wherein the first value is different from the second value.

The verification mark can be any character or combination of characters that is suitable for verification. The current verification mark can be understood as being issued by the self-generating wireless switch. Correspondingly, the historical verification mark can be understood as the The controlled device has been stored before the wireless switch is issued.

In some examples, the historical verification identification can be the current verification identification sent to the controlled device and stored by the controlled device when the self-generating wireless switch last operated, or determined according to it. In other partial examples, the historical verification identification can also be It may be the current verification identifier sent to the controlled device and stored by the controlled device when a specific manipulation action (such as a push-down manipulation action or a rebound manipulation action) occurred last time from the self-generating wireless switch, or determined based on it.

After receiving the current control message, the controlled device can verify whether the relationship between the current verification ID and the stored historical verification ID matches the conversion rule; and when the relationship matches the conversion rule, execute the The control event corresponding to the current control message.

If the relationship does not match the conversion rule, the corresponding message (such as the current control message) may be discarded; wherein, the discarding of the current control message can be understood as not processing based on the current control message, for example : Do not execute the control event corresponding to the current control message, and do not update and change information such as historical verification identifiers based on the current control message.

In the above scheme, by introducing the current verification identification in the interaction process between the self-generating wireless switch and the controlled device, the matching verification between the current verification identification and the historical verification identification can be used as the basis for executing the control event, and the execution of the control event of copying the message is avoided. The effect of anti-copy attack is realized. At the same time, through the matching verification of whether the current verification identifier and the historical verification identifier match the transformation rule, it can also provide a basis for filtering out duplicate messages.

Among them, the verification identifier in the real message (that is, the control information) is transformed, and the verification identifier in the copied message is usually repeated, and then, through verification based on historical verification identifiers and transformation rules, the duplicated message can be effectively verified (The relationship between the verification identifier and the historical verification identifier usually does not match the transformation rule), thereby avoiding the execution of the control action of copying the message and ensuring security.

In addition, when the historical verification mark is the current verification mark in the past, it can be guaranteed that the source of the verification mark comes from the self-generating wireless switch, thereby effectively guaranteeing the accuracy and security of the verification.

Due to the possibility of packet loss in wireless communication, if the data packet sent by the button (that is, the data packet of the control message sent after the button is pressed) is lost, the data packet sent by the rebound (that is, the rebound The data packet of the control message sent later) can be used as a remedy, and the controlled device can still respond after receiving the rebound data packet.

For this, the controlled device can judge whether to execute the control event based on the verification mark and the manipulation action represented by the control message. For example, the controlled device can judge according to the serial number (that is, the verification mark), if it is pressed The data packet (that is, the current control message is a pressed control message), must respond to execute the corresponding control event; if it is a rebound data packet (that is, the current control message is a rebound control message), Then only when the pressed data packet of the same serial number (ie, the verification identifier) has not been received before, the corresponding control event is executed in response.

It can be seen that if the control events corresponding to the press and the rebound are the same, the scheme of "only after a complete press and rebound occurs the change of the verification mark" can help to avoid the loss of data packets and affect the control event. Execution ensures that the corresponding control events can be effectively executed.

At the same time, after a reasonable configuration of the controlled device, it can also help to avoid repeated execution of the control message pointing to the same control event, for example: using a self-generating wireless switch to control a light (that is, the receiver is a light or connected light ), if the controlled control event is: the inversion of the light state, then: if both the press and the rebound respond, the light is turned on when the press is pressed, and then the light will be turned off after the rebound. The reasonable configuration can be, for example: if the self-generating wireless switch is pressed to change the current verification mark, then: the controlled device can update and write the current verification mark in it when receiving the current control message, as a new historical verification logo.

While achieving the above effects, even if the control events corresponding to the press and rebound in some controlled devices are different, after the controlled devices are reasonably configured, the realization of different control events can also be guaranteed. The reasonable configuration can be, for example: if the self-generating wireless switch changes the current verification mark when it is pressed down, then: the controlled device can only write the verification mark in it when it receives the current control message at the time of rebound, as a new History verification ID.

It can be seen that using the same set of update conditions for the verification mark (that is, changing the current verification mark only when the current manipulation is the target manipulation action) can not only meet the needs of the controlled device that the press and rebound correspond to the same control event, but also It can take into account the needs of controlled devices corresponding to different control events for pressing and rebounding. Furthermore, the compatibility of the self-generating wireless switch to various possible control requirements is effectively guaranteed, thereby improving the diversity of control realized by the control system.

In addition, the scheme of "the change of the verification mark occurs only after a complete press and rebound" can also save power. For example: if the serial number (that is, the current verification mark) is only updated when it rebounds, then: there is no need to update the serial number (that is, the current verification mark) when the button is pressed, especially saving the need to write the updated serial number energy consumption in memory.

In addition, when the serial numbers (ie, the current verification ID) corresponding to the manipulation action of pressing down and the manipulation action of rebounding are the same, it can also make it easier for the controlled device to deduplicate messages according to the serial number.

When the user presses the button of the self-generating wireless switch, he usually wants to get immediate feedback on the effect of the control. Furthermore, if the serial number is updated only when rebounding (that is, the target manipulation action is the manipulation action of rebounding), then all the electric energy when pressing down can be used for other tasks, especially sending signals, without spending power to update the serial number.

In one of the implementation manners, please refer to FIG. 5 and FIG. 6, the rectification module 111 includes a first rectification part 1111 and a second rectification part 1112; the first rectification part 1111 is electrically connected to the induction part 1032 and the energy storage module 105 , and the second rectification part 1112 is electrically connected to the induction part 1032 of the generator 103 and the energy storage module 105 .

In this way, when the generator is pressed down and reset, electric energy can be transmitted to the energy storage module 105 through the rectification device, so that signals can be sent when the wireless switch is pressed down and reset.

In one of the implementation manners, please refer to FIG. 10 , the voltage output module 106 may include: a controller 1061, an energy storage capacitor C61, and a freewheeling unit (for example, including a freewheeling inductor L61);

In one of the implementation manners, a method of sending packets and scanning and receiving data packets when using Bluetooth for communication will be described below.

Wherein, the controlled device receives the data packet according to the preset wake-up sleep cycle (it can also be understood as controlling the wake-up and sleep of the data packet receiving function of the controlled device according to the wake-up sleep cycle), in a specific example, the controlled The device itself can wake up and sleep according to the wake-up-sleep cycle. The wake-up-sleep cycle includes alternate wake-up periods and sleep periods, that is, after the wake-up period passes, it enters the sleep period, and after the sleep period passes, it enters the wake-up period, and the cycle repeats. . And the controlled device only receives data packets during the wake-up period.

In Fig. 11, the waveform of receiving and scanning is the schematic waveform of the controlled device receiving the scanning data packet, wherein the wake-up period can be represented as Ton, the sleep period can be represented as Toff, and the waveform of sending the packet is the schematic waveform of the data packet sent by the self-generating switch. The raised waveform is the sending period which can be regarded as a data packet.

When the processor sends the corresponding current control message to the controlled device through the first wireless communication module, it is specifically used for:

N groups of data packets are broadcast to the outside in sequence through Bluetooth, so that: the controlled device captures at least one data packet during the wake-up period, wherein each group of data packets includes a plurality of data packets, and each data packet contains the The current control message; the broadcast interval of adjacent data packets in the N groups of data packets is matched with the wake-up and sleep cycle of the controlled device, wherein, N≥2.

Correspondingly, in the controlled device, during the wake-up period, at least one data packet in the N groups of data packets sent by the self-generating wireless switch can be captured through Bluetooth, and the N groups of data packets are the self-generating wireless switches. The switch broadcasts to the outside world sequentially through Bluetooth, and each data packet contains the current control message; the broadcast interval between two adjacent data packets in the N groups of data packets matches the wake-up and sleep cycle of the controlled device, Among them, N≥2.

Among them, the broadcast interval can be understood as: the interval between the start broadcasting times of two adjacent groups of data packets, which can also be regarded as the broadcast cycle of each group of data packets, and only one group of data packets is sent in each broadcast cycle.

The duration of the wake-up period is greater than or equal to the broadcast 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 above solutions, it can help to ensure that during the process of sending and receiving data packets, no matter when the self-generating wireless switch sends data packets, the controlled device can receive the data packets during the wake-up period.

In the case that the wake-up period Ton is within the large cycle of sending packets, there must be at least 1 packet in the window of the wake-up period Ton, that is, it is impossible for the wake-up period Ton to fall within the broadcast interval (for example, 20mS), and the wake-up period Ton is greater than or equal to Broadcast interval (eg 20mS)

At the same time, it is also guaranteed that at least one packet falls outside the Toff window of the dormant period. Considering that the sending of the packet itself takes a certain period of time (for example, 1mS), the Toff of the dormant period must be guaranteed to be less than or equal to the broadcast interval * (N-1), for example, less than Or equal to 20mS*(N-1).

In a specific example, the specified packet sending interval (that is, the broadcast interval formed) can be selected as 20mS;

The wake-up sleep cycle of the controlled device can be 100mS;

The duty cycle can be 20%,

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

Under the above parameters, if the transmitter (that is, the self-generating wireless switch) can send 5 sets of data packets, the controlled device (ie, the controlled device) can scan at least 1 set of data packets. If the transmitter can send 10 sets of data packets, the controlled device can scan at least 2 sets of data packets.

In another specific example, if N=5, the wake-up period Ton can be specifically 25mS, the sleep period Toff can be specifically 75mS, and the corresponding duty cycle is 25%, and the controlled device can scan at least one group data packets, and leave a certain margin.

In another specific example, the wake-up sleep period can be 125mS, the wake-up period Ton can be specifically 25mS, and the sleep period can be specifically 100mS. Correspondingly, if the packet sending interval is 20mS, then: 20mS*(N-1) needs to be greater than or It is equal to 100 mS, furthermore, N≥6 (that is, at least 6 groups of data packets need to be sent), wherein, when N=6, at least one group of data packets is scanned within the wake-up period.

In a further example, multiple data packets in the same group are sent through at least two of the following channels:

2.402GHz; 2.428GHz; 2.480GHz.

Correspondingly, when the processor 108 sequentially broadcasts N groups of data packets through the Bluetooth module, it is specifically used for:

After starting to send a group of data packets, time the broadcast interval, and send another corresponding group of data packets when the timing reaches the specified packet sending interval.

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

In a specific example, the signal transmitted by the first wireless communication module is a bluetooth signal, for example, 2.4GHZ may be used as the carrier frequency, and data packets are respectively transmitted through a designated bluetooth channel. Specifically, the self-generating Bluetooth switch uses Bluetooth low energy technology to transmit data in 40 2-MHz channels. Advantageously, the data is transmitted on a broadcast channel. The frequencies of the three broadcast channels are: 2.402GHz for channel 37; 2.428GHz for channel 38; 2.480GHz for channel 39.

Among them, more than one packet of signal will be sent each time it is pressed, for example, 3-10 packets of data can be sent. The processor may be integrated with the timing module mentioned above, and the timing module is used for delay in the sending interval.

In one example, the packet sending interval can be 20mS, specifically, it can fluctuate randomly within the range of 20mS±5mS (that is, the specified packet sending interval can be within the range of 15 milliseconds to 25 milliseconds), so as to reduce the difference The probability of a packet sent by the switch colliding in the air.

In one of the implementation manners, the self-generating wireless switch further includes a light-emitting module 115 and a light-transmitting part 116, the light-emitting module 115 is connected to the circuit board 114, and the light-emitting module 115 is arranged on the light-transmitting part 116. part 116 inside; the light emitting module 115 is configured to emit light when the wireless switch button 101 is pressed and/or rebounded (for example, it can emit light or flash when any button is fully pressed, and can also be used when the corresponding button is fully pressed. only light up or flash when pressed), and transmit light to the outside through the light-transmitting part, which can be specifically realized through the corresponding configuration of the circuit.

The light-transmitting portion 116 can be, for example, a light-guiding rod.

For example: the light-emitting module 115 includes a light-emitting diode, the positive pole of the light-emitting diode is connected to the positive pole of the energy storage module, and the negative pole of the light-emitting diode is connected to the negative pole of the energy storage module through a switch tube; wherein, the switch tube The control end of the control terminal is connected to the processor, or: the switch tube is a switch tube integrated in the processor.
