[0039] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0040] It should be noted that the Bluetooth electro-optical conversion device can be understood as a kind of Bluetooth optical head.

[0041] In the related art, a Bluetooth optical head is used to dock with the optical communication port of any one of a power meter, a heat meter, a water meter, a gas meter, etc. to perform data exchange. Specifically, the Bluetooth optical head is provided with a Bluetooth communication function, and the terminal device is also provided with a Bluetooth communication function. The Bluetooth optical head is Bluetooth communication-connected to the terminal device, so that parameter configuration and data reading management and storage can be performed on the meter end.

[0042] It can be seen that the Bluetooth optical head in the related art must be Bluetooth-connected to the terminal device to perform data transmission, and the data transmitted by the meter end is sent to the terminal device to complete the reading. That is, the Bluetooth optical head in the related art cannot be used alone. After analysis, it is found that the reason why the Bluetooth optical head in the related art cannot be used alone is that it does not have a data storage function.

[0043] Furthermore, through research, it is found that: the functions realized by the Bluetooth optical head in the related art based on simple basic communication functions are limited, and the local control performance of the Bluetooth optical head needs to be improved. When facing the meter ends in various countries, the Bluetooth optical head in the related art cannot meet the configuration requirements of different communication port parameters, its compatibility needs to be improved, and the configuration operation process needs to be simplified.

[0044] Please refer to Figure 1a , this embodiment of the specification provides a Bluetooth electro-optical conversion device 100, which includes a control module 110, a data storage module 120, a button input module 130, a power supply processing module 140, a Bluetooth communication module 150, and an interface display module 160 that are respectively connected to the control module 110.

[0045] The power processing module 140 supplies electrical energy to the data storage module 120, the Bluetooth communication module 150, and the interface display module 160 respectively. The Bluetooth electro-optical conversion device 100 is connected to the terminal device 200 through the Bluetooth communication module 150. The data storage module 120 receives the data read from the meter and stores it locally; when the Bluetooth electro-optical conversion device 100 is connected to the terminal device 200, the stored meter reading data is transmitted to the terminal device 200 through the Bluetooth communication module 150. The button input module 130 receives the function configuration signal and sets the Bluetooth electro-optical conversion device 100 to the state corresponding to the function configuration signal. The interface display module 160 is used to display the working state and parameter configuration state of the Bluetooth electro-optical conversion device 100.

[0046] Among them, the control module 110 can be understood as the MCU control center module, which is used to control the operation of the entire Bluetooth electro-optical conversion device 100. After the power processing module 140 performs secondary step-down and filtering processing on the power supply, it then supplies the working power of each module such as the data storage module 120, the Bluetooth communication module 150, and the interface display module 160.

[0047] Since the Bluetooth optical head in the related technology does not have a data storage function, the Bluetooth optical head must be communicatively connected to the terminal device. Therefore, the Bluetooth optical head in the related technology cannot be used alone. In this embodiment, the data storage module 120 is provided for the Bluetooth electro-optical conversion device 100, and the data storage module 120 can receive and locally store the data read from the meter. Thus, it can be used alone when the Bluetooth electro-optical conversion device 100 is not communicatively connected to the terminal device 200.

[0048] It should be noted that the Bluetooth electro-optical conversion device 100 can not only be used alone without being communicatively connected to the terminal device 200, but also transmit the stored meter reading data to the terminal device 200 when it is connected to the terminal device 200 through the Bluetooth communication module 150.

[0049] Please refer to Figure 1b , Figure 1b The circuit schematic diagram of the Bluetooth communication module 150 is shown, including the antenna ANT1, the chip U6, and the peripheral circuit of the chip U6, where the chip U6 is the Tuoda chip TD5322A. Exemplarily, please continue to refer to Figure 1b, when receiving data transmission using the Bluetooth communication module 150, the antenna ANT1 receives the data signal transmitted by the terminal device 200, and inputs it into the chip U6 through the 4th pin of the chip U6 via the capacitive matching network for processing. The processed data signal is output from the 8th pin of the chip U6 and transmitted to the corresponding input port of the MCU chip in the control module 110 via the network port; when sending data transmission using the Bluetooth communication module 150, the chip U6 receives the data signal sent from the corresponding output port of the MCU chip in the control module 110 through the 7th pin, and the chip U6 processes the data signal. The processed data signal is transmitted to the terminal device 200 through the antenna ANT1 via the 4th pin of the chip U6.

[0050] Furthermore, the Bluetooth electro-optical conversion device 100 is further provided with a key input module 130 and an interface display module 160. The user can operate the key input module 130 to receive a function configuration signal, and set the Bluetooth electro-optical conversion device 100 to be in a state corresponding to the function configuration signal through the function configuration signal.

[0051] Please refer to Figure 1c , Figure 1c shown is the circuit schematic diagram of the key input module 130. Specifically, the key input module 130 receives the data signal sent from the corresponding output port of the MCU chip in the control module 110 through the network port, and controls the on-off of the switch in the control circuit to complete different functions of the Bluetooth electro-optical conversion device 100 respectively. Exemplarily, KEY1, KEY3, and POWER_KEY are three network ports of the key input module 130, which are controlled by the data signal sent from the corresponding output port of the MCU chip in the control module 110. When receiving the data signal sent from the corresponding output port of the MCU chip in the control module 110, KEY1 controls the switch SW1 in the key input module 130, KEY2 controls the switch SW2 in the key input module 130, and POWER_KEY controls the switch SW3 in the key input module 130. Different functions of the Bluetooth electro-optical conversion device 100 are controlled by controlling the on-off of the switch. Among them, different functions can be manifested by different states during the normal operation of the Bluetooth electro-optical conversion device 100, such as: shutdown, menu selection, confirmation, return, etc.

[0052] During the process of setting the Bluetooth electro-optical conversion device 100 through the key input module 130, the interface display module 160 simultaneously displays the working state and parameter configuration state of the Bluetooth electro-optical conversion device 100 to visually show the configuration state to the user and simplify the product operation process. Please refer to Figure 1d , Figure 1d shown is the circuit schematic diagram of the interface display module 160.

[0053] It should be noted that the button input module 130 can improve the local control performance of the Bluetooth electro-optical conversion device 100. Further, by using the button input module 130 and the interface display module 160 in cooperation, the configuration of the Bluetooth electro-optical conversion device 100 is realized, and the configuration process no longer needs to rely on a terminal device.

[0054] Please refer to Figure 1e , Figure 1e shown is the circuit schematic diagram of the control module 110, where the control module 110 includes an MCU chip and its peripheral circuits. Optionally, the MCU chip in the control module 110 uses a CH583M chip. Specifically, the CH583M chip is a 32-bit RISC microcontroller integrating BLE wireless communication. It integrates rich peripheral resources such as a 2Mbps low-power Bluetooth BLE communication module, 2 full-speed USB host and device controllers and transceivers, 2 SPIs, 4 serial ports, an ADC, a touch button detection module, an RTC, etc.

[0055] It should be noted that the terminal device can be any one of a mobile terminal, a computer device, and a wearable device.

[0056] In the above embodiments, by setting a data storage module for the Bluetooth electro-optical conversion device, the data storage module can receive and store the data read from the meter and perform local storage. Thus, it can be used alone when the Bluetooth electro-optical conversion device is not communicatively connected to the terminal device. Further, the Bluetooth electro-optical conversion device is also provided with a button input module and an interface display module. Not only can the button input module improve the local control performance of the Bluetooth electro-optical conversion device; but also by using the button input module and the interface display module in cooperation, the configuration of the Bluetooth electro-optical conversion device is realized, simplifying the product configuration process and improving the product operability.

[0057] In some embodiments, please refer to Figure 2a , the Bluetooth electro-optical conversion device 100 further includes an infrared transceiver module 210 connected to the control module 110. The Bluetooth electro-optical conversion device 100 is connected to the meter end 300 through the infrared transceiver module 210.

[0058] In some cases, the meter end 300 is provided with an infrared transceiver function, and the remote data transmission and communication functions are realized through this infrared transceiver function. Therefore, in order to better interact with the meter end 300 for data, the Bluetooth electro-optical conversion device 100 further includes an infrared transceiver module 210, and the infrared transceiver module 210 is connected to the control module 110.

[0059] Among them, the infrared transceiver module 210 may include an infrared receiving unit and an infrared transmitting unit. The infrared receiving unit may be configured to receive the infrared optical signal emitted from the meter end, and convert the infrared optical signal into an electrical signal and input it to the control module 110. The infrared transmitting unit may be configured to convert the electrical signal input by the control module 110 into an infrared optical signal and transmit it to the optical and electrical interface end of the meter end. Please refer to Figure 2b , Figure 2b The circuit schematic diagram of the infrared receiving unit is shown as Figure 2c The circuit schematic diagram of the infrared transmitting unit is shown as, including: light-emitting diode D9, photosensitive triode Q8, infrared chip U5 and the peripheral circuit of infrared chip U5. Preferably, the infrared chip U5 is an AIP74LVC1G logic signal processing gate circuit chip.

[0060] Exemplarily, when using the infrared receiving unit for receiving data transmission, please continue to refer to Figure 2a , the photosensitive triode Q8 receives the data signal transmitted from the meter end 300, inputs it to the second pin of the infrared chip U5, and after being processed by the infrared chip U5 for the data signal, it is output from the fourth pin of the infrared chip U5 and the data signal is transmitted to the MCU chip in the control module 110; when using the infrared transmitting unit for transmitting data transmission, please continue to refer to Figure 2b , the infrared chip U5 receives the data signal transmitted from the corresponding output port of the MCU chip in the control module 110 through the second pin, and the infrared chip U5 processes the data signal. The processed data signal controls the operation of the light-emitting diode D9 through the fourth pin of the infrared chip U5, and converts the electrical signal transmitted from the corresponding output port of the MCU chip in the control module 110 into an infrared optical signal and transmits it to the meter end 300. Optionally, a triode and a pull-down resistor, such as triode Q3 and resistor R8, can be added to the peripheral circuit, which can effectively improve the system operation speed and make the performance of the Bluetooth electro-optical conversion device 100 better.

[0061] It should be noted that the meter end 300 may be any one of an electric energy meter, a heat meter, a water meter, a gas meter, etc.

[0062] In some embodiments, the control module is provided with a first serial interface. The Bluetooth communication module is connected to the control module through the first serial interface.

[0063] Specifically, in order to improve the data transmission efficiency and reliability, the Bluetooth communication module 150 is connected to the control module 110 by using a serial interface. Therefore, the control module 110 is provided with a first serial interface, and is connected to the control module 110 through the first serial interface via the Bluetooth communication module 150.

[0064] In some embodiments, the control module is further provided with a second serial interface. The infrared transceiver module is connected to the control module through the second serial interface.

[0065] Specifically, in order to improve data transmission efficiency and reliability, the infrared transceiver module 210 is connected to the control module 110 using a serial interface. Therefore, the control module 110 is provided with a second serial interface, and the infrared transceiver module 210 is connected to the second serial interface of the control module 110.

[0066] In some embodiments, the infrared transceiver module receives an infrared signal emitted by the meter end and converts it into a first electrical signal, and transmits the first electrical signal to the control module through the second serial interface. The control module transmits the first electrical signal after protocol conversion to the Bluetooth communication module through the first serial interface.

[0067] Specifically, the meter end 300 has an infrared transceiver function and emits an infrared signal. The infrared transceiver module 210 receives the infrared signal. The infrared transceiver module 210 converts the infrared signal into a first electrical signal. Since the infrared transceiver module 210 is connected to the second serial interface of the control module 110, the infrared transceiver module 210 transmits the first electrical signal to the control module 110 through the second serial interface. The control module 110 performs protocol conversion to obtain the first electrical signal after protocol conversion. The control module 110 transmits the first electrical signal after protocol conversion to the Bluetooth communication module 150 through the first serial interface.

[0068] In some embodiments, the control module receives a second electrical signal output by the Bluetooth communication module through the first serial interface. The control module transmits the second electrical signal after protocol conversion to the infrared transceiver module through the second serial interface.

[0069] Specifically, the Bluetooth communication 150 module is connected to the first serial interface of the control module 110. The Bluetooth communication module 150 transmits a second electrical signal to the control module 110 through the first serial interface. The control module 110 receives the second electrical signal and performs protocol conversion on the second electrical signal to obtain the second electrical signal after protocol conversion. Since the infrared transceiver module 210 is connected to the second serial interface of the control module 110, the control module 110 transmits the second electrical signal after protocol conversion to the infrared transceiver module 210 through the second serial interface.

[0070] In some embodiments, the data storage module communicates with the control module using the SPI method. Among them, SPI (Serial Peripheral Interface) is a synchronous serial communication interface used to transmit data between digital systems. Since SPI communication is synchronous and data transmission is directly completed at the hardware level, SPI can achieve a relatively high data transmission rate. Therefore, the data storage module 120 can communicate with the control module 110 using the SPI method.

[0071] Exemplarily, please refer to Figure 3 , the data storage module 120 may adopt the circuit schematic diagram shown Figure 3 . Among them, the data storage module 120 includes a storage chip U13 and its peripheral circuit. Optionally, the storage chip U13 adopts a W25Q128JVSIQ chip. The W25Q128JVSIQ chip is a 128M-bit serial NOR flash memory chip, which has characteristics such as large capacity, high-speed read and write, SPI interface communication, and low power consumption, and can be applied to this embodiment to complete the data storage function. The data storage module can be understood as an application memory. The control module can be understood as an MCU control center. The application memory is connected to the MCU control center, and data storage is performed through the application memory, so as to achieve local management. Furthermore, the Bluetooth optical head can operate independently without connecting to a terminal device.

[0072] Among them, whether to perform data storage is selective. If the data storage function of the Bluetooth electro-optical conversion device 100 is required, it can be implemented through the data storage module 120. Specifically, pins 5, 6, 1, and 2 of the storage chip U13 constitute a communication port for realizing SPI communication connection with the MCU chip in the control module 110, and selectively process whether to store data. Exemplarily, if it is selected to store data, after the data signal sent by the terminal device 200 is processed by the Bluetooth communication module 150 and input into the MCU chip in the control module 110, the MCU chip will also control the data storage module 120 to store data through the SPI communication port of the MCU chip, and store the data into the data storage module.

[0073] In some embodiments, please refer to Figure 4 , the key input module 130 is provided with three keys.

[0074] In some embodiments, the interface display module displays at least one of communication status information and power supply status information. Specifically, please refer to Figure 5 , the Bluetooth electro-optical conversion device 100 is provided with an interface display module 160. The interface display module 160 can display communication status information or power supply status information. In this embodiment, by setting the interface display module 160, a data interaction interface is realized, so that the communication status, parameter configuration of the Bluetooth optical head, and battery power can be intuitively displayed.

[0075] In some embodiments, please refer to Figure 6 , the Bluetooth electro-optical conversion device 100 is provided with a display screen 510, a first key 520, a second key 530, and a third key 540.

[0076] Among them, the first button 520, the second button 530, and the third button 540 are respectively used to control the Bluetooth electro-optical conversion device 100 to perform local operations and maintain or switch the working state of the Bluetooth electro-optical conversion device 100. Exemplarily, in cooperation with the interface display module, the first button 520 can be used as a menu and selection button. Long pressing it switches to the menu tab interface, and short pressing it switches different function options of the Bluetooth electro-optical conversion device 100. Optionally, its function options may include: switching the read data state and the write data state; switching the data storage state and the non-storage state. The second button 530 can be used as a spare button to control the Bluetooth electro-optical conversion device 100 to implement other functions. Optionally, other functions of the Bluetooth electro-optical conversion device 100 include but are not limited to operations such as reset, refresh, and returning to the main interface. The third button 540 can be used as a power and confirmation button. Long pressing it controls the Bluetooth electro-optical conversion device 100 to switch the operating state or the off state, and short pressing it controls the Bluetooth electro-optical conversion device 100 to confirm the switch to the function state currently displayed on the display screen.

[0077] In this embodiment, by connecting the display screen and the independent buttons to the control module 110, local operations can be performed through the Bluetooth electro-optical conversion device 100, and the functions of the Bluetooth electro-optical conversion device 100 can be diversified.

[0078] In some embodiments, the power supply of the power processing module comes from a USB port or a battery. The power processing module includes a secondary buck module and a filtering module.
