[0055] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0056] Example 1

[0057] This embodiment provides a method for transmitting kitchenware information based on visible light communication, wherein the kitchenware includes an indicator light, Figure 1 , the kitchenware information transmission methods include:

[0058] S11. In the information transmission mode, a character string to be sent is generated according to the information to be transmitted and a preset character string format.

[0059] S12. Convert the character string to be sent into binary code according to a preset character set.

[0060] S13, controlling the on and off of the indicator light according to the preset modulation rule and binary code.

[0061] The indicator light can be a commonly found indicator light in kitchenware (such as a power indicator light). By adding a light modulation software code, the kitchenware can modulate the information to be transmitted onto the indicator light in a specific mode, so that a certain indicator light turns on and off quickly or changes brightness quickly according to the modulation rules, so that the relevant information is cyclically output in the form of visible light, and the relevant information is parsed and presented in plain text by the light receiving device. The frequency range of on and off or brightness change is 120Hz (Hertz) to 115200Hz, and the data transmission speed is 120bps (bits per second) to 115200bps, which is a flickering frequency that is invisible to the naked eye.

[0062] The information that needs to be transmitted may include but is not limited to: anti-counterfeiting information, fault record information, factory date information, etc.

[0063] The light receiving device can be used as Figure 2 The short-distance visible light communication circuit shown in the figure comprises: a photoelectric conversion module 1 , a bias voltage module 2 and a comparison shaping module 3 .

[0064] The photoelectric conversion module 1 is used to convert the received light intensity signal into a voltage signal Uin, and output the voltage signal Uin to the input end of the bias voltage module 2 and the first input end of the comparison shaping module 3 respectively.

[0065] The bias voltage module 2 is used to filter the voltage signal Uin to obtain a DC bias voltage DCbias, and output the DC bias voltage DCbias to the second input terminal of the comparison shaping module 3. The DC bias voltage DCbias is between the peak value and the valley value of the voltage signal Uin.

[0066] The comparison and shaping module 3 is used to compare the voltage signal Uin with the DC bias voltage DCbias, and generate a communication signal Out according to the comparison result.

[0067] The bias voltage module 2 may use a low-pass filter circuit to filter out the DC component of the voltage signal Uin, namely, the DC bias voltage DCbias.

[0068] The communication signal Out generated by the comparison shaping module 3 is directly input into the digital input port of the MCU (micro control unit) for analysis. The MCU can display the analyzed information on the display screen for maintenance personnel to view.

[0069] The DC bias voltage DCbias is within a preset range of the median of the peak and valley values. Since the comparator output inversion requires the input inversion to reach a certain value, this value is generally very small, such as 10mV (millivolts). Therefore, the closer the DC bias voltage DCbias is to the median of the peak and valley values ​​of the voltage signal Uin, the more sensitive the circuit can be. In this case, the bit of the data can be encoded according to the duration of the voltage signal Uin level.

[0070] The photoelectric conversion module 1 includes: a photoelectric receiving diode D1 and a first resistor R1. The cathode of the photoelectric receiving diode D1 is electrically connected to the power supply voltage, the anode of the photoelectric receiving diode D1 is electrically connected to the first end of the first resistor R1, and the second end of the first resistor R1 is grounded. The anode of the photoelectric receiving diode D1 outputs a voltage signal Uin.

[0071] The bias voltage module 2 includes: a second resistor R2 and a first capacitor C1. The first end of the second resistor R2 receives the voltage signal Uin, the second end of the second resistor R2 is electrically connected to the first end of the first capacitor C1, and the second end of the first capacitor C1 is grounded. The second end of the second resistor R2 outputs a DC bias voltage DCbias. Among them, the second resistor R2 and the first capacitor C1 form a low-pass filter circuit, which will extract the DC component of the voltage signal Uin at both ends of the first resistor R1, that is, the DC bias voltage DCbias, at both ends of the first capacitor C1. The stable value of DCbias is between the peak value and the valley value of Uin. Using the DC bias voltage DCbias as an input of the comparison shaping module 3 can realize automatic adjustment of the DC bias voltage with the ambient light and the emission light intensity.

[0072] The comparison shaping module 3 includes: a comparator CMP and a third resistor R3. The inverting input terminal of the comparator CMP is used as the first input terminal of the comparison shaping module 3, and the non-inverting input terminal of the comparator CMP is used as the second input terminal of the comparison shaping module 3. The first end of the third resistor R3 is electrically connected to the power supply voltage, and the second end of the third resistor R3 is electrically connected to the output terminal of the comparator CMP. The output terminal of the comparator CMP outputs the communication signal Out.

[0073] The string format, character set, and modulation rules can be set according to actual needs.

[0074] This embodiment generates a character string to be sent according to information and a preset character string format, converts the character string to be sent into a binary code according to a preset character set, controls the on and off of the indicator light according to a preset modulation rule and the binary code, utilizes the indicator light of the kitchenware itself as a visible light source, and outputs the information to be transmitted based on visible light communication. No hardware needs to be added to the kitchenware, and compared with the wired transmission method, the operation is simplified; compared with the method in which the indicator light directly transmits information to the human eye, the information transmission speed is fast, the amount of information that can be transmitted is greatly increased, and the content that can be consulted is rich.

[0075] In specific implementation, the string format is: header code + information + LCR check string + tail code.

[0076] The header code and the tail code can both be one byte, containing 8 bits. For example, the header code can be "\f" and the tail code can be "\b". The header code and the tail code can both be selected from ASCII control characters, but cannot be control characters such as "\n", "\r", and "\t". The information string is valid only when the LCR (longitudinal redundancy check) check passes.

[0077] The information may include a data string and a command string. The command string at least includes a screen clearing instruction. For example, the information string of the screen clearing instruction is set to "-ClearScreen". The command string may generally not be displayed.

[0078] In a specific implementation, the character set includes at least one of the ASCII character set and the GB2312 character set.

[0079] In a specific implementation, the modulation rule includes at least one of Morse coding rule, Manchester coding rule and user-defined coding rule.

[0080] Among them, in the custom coding rule, the bits of the binary code are encoded according to the duration of a single on-off state, and the single on-off state includes a single light-on state and a single light-off state.

[0081] When implementing it, refer to Figure 3 , custom encoding rules include:

[0082] The duration of a single on-off state is 1 unit time (T), and the corresponding bit is "0".

[0083] The duration of a single on-off state is 2 unit durations (2T), and the corresponding bit is "1".

[0084] Among them, 2T off and 2T on both represent "1", and 1T off and 1T on both represent "0".

[0085] In such Figure 2 and Figure 3 In the example, since the duration of a single on-off state of the light intensity signal is 1 unit time, the corresponding bit is "0", and the duration of a single on-off state is 2 unit time, the corresponding bit is "1", the maximum value DCmax and the minimum value DCmin of the DC component of the voltage signal Uin can be obtained by measuring the data by transmitting specific data with specific encoding.

[0086] When the received light intensity signal represents "1010" binary data and uses a high level encoding bit "1" of 2 unit duration, the maximum value DCmax of the DC component of the voltage signal Uin is expressed by the following formula:

[0087] DCmax=(2*peak value+valley value) / 3=(peak value+valley value) / 2+(peak value-valley value) / 6.

[0088] When the received light intensity signal represents "1010" binary data and uses a valley encoding bit "1" of 2 unit duration, the minimum value DCmin of the DC component of the voltage signal Uin is expressed by the following formula:

[0089] DCmin=(peak value+2*valley value) / 3=(peak value+valley value) / 2-(peak value-valley value) / 6.

[0090] During specific implementation, the kitchenware information transmission method further includes:

[0091] In the information transmission mode, when the custom coding rules are adopted, when there is no binary code that needs to be transmitted, the control indicator light continuously outputs the "start / stop" position.

[0092] Custom encoding rules also include:

[0093] The duration of a single on / off state is 4 unit durations (4T), and the corresponding bit is the "start / stop" bit.

[0094] As long as there is no content to be sent, the "start / stop" bit is always sent to ensure that the DC bias voltage is always close to the middle of the high level (peak value of Uin) and the low level (valley value of Uin). At the same time, the receiving end software can also reset the next reception according to the "start / stop" bit.

[0095] When implementing it, refer to Figure 4 , the kitchenware information transmission method also includes:

[0096] S21. Obtaining key input information of kitchenware.

[0097] S22: When the key input information meets the preset transfer mode entry condition, switch to the information transfer mode.

[0098] S23: When the key input information meets the preset transfer mode switching condition, switch out of the information transfer mode.

[0099] Among them, the transfer mode cut-in condition and the transfer mode cut-out condition can be set according to actual needs.

[0100] During specific implementation, the kitchenware information transmission method further includes:

[0101] In the information transmission mode, the information to be transmitted is determined according to the key input information and the preset correspondence between the key and the information item.

[0102] Among them, the corresponding relationship between the buttons and the information items can be set according to actual needs.

[0103] Example 2

[0105] The character string generation module 11 is used to generate a character string to be sent according to the information to be transmitted and a preset character string format in the information transmission mode.

[0106] The binary conversion module 12 is used to convert the character string to be sent into binary code according to a preset character set.

[0107] The indicator light output module 13 is used to control the on and off of the indicator light according to a preset modulation rule and a binary code.

[0108] The indicator light can be a commonly found indicator light in kitchenware (such as a power indicator light). By adding a light modulation software code, the kitchenware can modulate the information to be transmitted onto the indicator light in a specific mode, so that a certain indicator light turns on and off quickly or changes brightness quickly according to the modulation rules, so that the relevant information is cyclically output in the form of visible light, and the relevant information is parsed and presented in plain text by the light receiving device.

The DC bias voltage DCbias is between the peak value and the valley value of the voltage signal Uin.

[0113] The comparison and shaping module 3 is used to compare the voltage signal Uin with the DC bias voltage DCbias, and generate a communication signal Out according to the comparison result.

[0114] The bias voltage module 2 may use a low-pass filter circuit to filter out the DC component of the voltage signal Uin, namely, the DC bias voltage DCbias.

[0115] The communication signal Out generated by the comparison shaping module 3 is directly input into the digital input port of the MCU (micro control unit) for analysis. The MCU can display the analyzed information on the display screen for maintenance personnel to view.

[0116] The DC bias voltage DCbias is within a preset range of the median of the peak and valley values.

Therefore, the closer the DC bias voltage DCbias is to the median of the peak and valley values ​​of the voltage signal Uin, the more sensitive the circuit can be. In this case, the bit of the data can be encoded according to the duration of the voltage signal Uin level.

The output terminal of the comparator CMP outputs the communication signal Out.

[0120] The string format, character set, and modulation rules can be set according to actual needs.
