[0026] The embodiments of the present application will be described below in combination with Figures 1 to 6

[0027] As Figure 1 ​As shown, according to the embodiment of the utility model, provide a kind of data communication converter 100 based on smart phone, including: master module 110, with USB interface and signal transmission interface, USB interface is suitable for being connected with smart phone 200 communication, to obtain the control instruction of smart phone 200;Isolation module 120, with signal transmission interface and controlled device 300 respectively communication connection, isolation module 120 carries out electrical isolation in the transmission process of control instruction to controlled device 300, and makes the equipment to master module 110 charges.

[0028] In this embodiment, the data communication converter based on smart phone 200 mainly includes master module 110 and isolation module 120. The master module 110 is equipped with a USB interface, which is used to communicate with the smart phone 200, so that the master module 110 can receive control instructions from the smart phone 200. The master module 110 is also provided with a signal transmission interface, which can transmit the control instructions received by the master module 110 to the isolation module 120, so that the isolation module 120 and the master module 110 can exchange data. The isolation module 120 has a dual role. First, it can be connected with the signal transmission interface to ensure that the control instructions sent by the master module 110 can be accurately transmitted to the controlled device 300. Second, the isolation module 120 provides electrical isolation during the transmission of the control instructions, which can ensure that there is no direct electrical connection between the master module 110 and the controlled device 300, thereby preventing electrical faults from spreading from one device to another. This greatly enhances the safety of the entire system and protects the master module 110 from the electrical interference or faults that may be generated by the controlled device 300. The controlled device 300 can charge the master module 110, so that the master module 110 can obtain power from the controlled device 300 to maintain its operation.

[0029] In this embodiment, the smart phone 200 communicates with the master module 110 through the USB interface and sends control instructions, which are then safely transmitted to the controlled device 300 through the isolation module 120. At the same time, the controlled device 300 can provide power to the master module 110, improving the safety and flexibility of the data communication converter based on smart phone 200 and improving the efficiency of device control.

[0030] Further, the master module 110 includes a processor 111 with a USB interface, a signal transmission interface, and an authentication interface. An authentication module 112 is connected with the authentication interface and is adapted to obtain information of the smart phone 200 to authenticate the smart phone 200.

[0031] In this embodiment, the main control module 110 mainly includes a processor 111 and an authentication module 112. The processor 111 is responsible for executing program instructions, processing data, and controlling the work of other modules. The smartphone 200 communicates with the main control module 110 through a USB cable, sends control instructions or receives data. The signal transmission interface is used to transmit the control instructions received by the processor 111 to the isolation module 120, and then control the controlled device 300. For example, data interaction can be carried out with the isolation module 120 in a wireless manner through UART. The authentication interface is used for communication with the authentication module 112, to ensure that only the smartphone 200 that has passed the authentication can interact with the main control module 110. Among them, the authentication module 112 verifies the identity of the connected smartphone 200. Based on the obtained information, the authentication module 112 will perform a series of verification processes to determine whether the smartphone is authorized to communicate with the main control module 110. If the smartphone 200 passes the authentication, the authentication module 112 will notify the main control module 110 to allow the smartphone 200 to perform further communication and control operations. If the authentication fails, the main control module 110 will refuse the control request of the smartphone to protect the security of the system.

[0032] Therefore, the main control module 110 not only can receive and process the control instructions of the smartphone, but also can ensure that these instructions come from the authenticated smartphone, thereby improving the security and reliability of the entire system.

[0033] As Figure 2As shown, the processor 111 is provided with several pins, among which, pin PA0-WKUP: indicates that the PA0 pin has a wake-up function. PA13 / JTMS / SWDIO: indicates that the PA13 pin can be used as JTAG test mode selection, serial wire debug data input / output. PB2 / BOOT1: indicates that the PB2 pin is used for boot mode selection. Power and ground: VDD and VSS pins are used to provide power supply and ground. For example, VDD_1 to VDD_4: indicate the power supply pins of the processor 111. VSS_1 to VSS_4: indicate the ground pins of the processor 111. NRST: reset pin, used to reset the processor 111. BOOT0: boot mode selection pin, used to select the boot mode of the processor 111. VBAT: backup battery input, used for real-time clock. OSC_IN / PD0 and OSC_OUT / PD1: external crystal oscillator input and output pins. PC14-OSC32_IN and PC15-OSC32_OUT: 32.768 kHz external crystal oscillator input and output pins, usually used for RTC. PA13 / JTMS / SWDIO and PA14 / JTCK / SWCLK: used for JTAG or SWD (serial wire debug) interface, used for debugging and programming the processor 111. PC13-TAMPER-RTC: has anti-tamper and RTC functions. PA8, PA9, PA10, PA11, PA12: these pins can have multiple functions, depending on the configuration of the processor 111.

[0034] Further, the smart phone 200 is an Apple phone, and the authentication module 112 is an MFI authentication chip.

[0035] Since the smart phone 200 is an Apple phone, the authentication module 112 adopts MFI (Made for iPhone / iPod / iPad, referred to as MFI) authentication. MFI authentication is a kind of identification use permission of Apple company for external accessories produced by its authorized accessory manufacturers, aiming to ensure that these accessories are compatible with Apple products and meet Apple's quality standards. The authentication module 112 communicates with the main control module 110 through the authentication interface, obtains the information of the smart phone 200 to authenticate the smart phone 200, and ensures that only the authenticated device can interact with the converter, thereby ensuring the safety and reliability of the system.

[0036] The MFI authentication module 112 includes a 3959 circuit and an MFI343S00177 circuit, which are used for MFI authentication chips to ensure the compatibility of the iPhone phone with the communication converter. The processor 111 performs I2C data transmission with the MFI authentication chip to use the MFI authentication chip, and after authentication, iap2 communication can be established with the iPhone phone.

[0037] As Figure 3As shown, the authentication module 112 is provided with an authentication circuit diagram, in which two I2C interfaces are used for communication with the microprocessor. An I2C bus expander or isolator is used. The VSS and VCC pins are connected to ground and a 3.3V power supply, respectively, to power the chip. SDA and SCL are the data and clock lines of the I2C bus, connected to the 3.3V power supply through pull-up resistors R12 and R11 (2.2kΩ), respectively. These resistors ensure that the bus is high in the idle state. C13 is a decoupling capacitor used to stabilize the power supply voltage and reduce power supply noise. U4 may be an I2C EEPROM. The VSS and VDD pins are connected to ground and a 3.3V power supply, respectively, to power the device. The WP is a write protection pin connected to ground, allowing write operations to the device. The SCL and SDA pins are the clock and data lines of the I2C bus. The I2C bus is a two-wire serial communication protocol, with SDA and SCL used for data transmission and clock synchronization, respectively. Pull-up resistors are essential for the proper operation of the I2C bus, ensuring that the bus remains high when no device is driving it. Decoupling capacitors help filter out high-frequency noise on the power supply lines, providing a stable power supply for I2C devices.

[0038] The data communication converter not only receives and processes control instructions from the Apple iPhone, but also ensures that the instructions come from an authenticated device, while achieving electrical isolation during the transmission of control instructions, and allowing the controlled device 300 to charge the master module 110, thereby improving the safety, reliability and convenience of the entire system.

[0039] Further, the isolation module 120 includes a digital isolator 121 having a first signal end 1201 in communication with the signal transmission interface, and a transceiver 122 having a second signal end 1202 in communication with the digital isolator 121, the second signal end 1202 being adapted to output control instructions.

[0040] In this embodiment, the isolation module 120 mainly includes a digital isolator 121 and a transceiver 122. The digital isolator 121 transmits digital signals between different voltage domains while maintaining electrical isolation. The digital isolator 121 transmits signals through non-electrically conductive media such as light, electromagnetic field or electric field, thereby achieving isolation. The digital isolator 121 can isolate circuits between analog and digital signals to prevent mutual interference. The transceiver 122 is in communication with the digital isolator 121 and is responsible for converting the signals received by the digital isolator 121 into a format suitable for the controlled device 300 to receive. The transceiver 122 can convert signals and transmit them on communication lines. It usually includes a transmitter and a receiver, which are used to convert data between different signal formats.

[0041] The combination of the digital isolator 121 and the transceiver 122 not only improves the anti-interference ability of the system, but also ensures the reliability and stability of data transmission. The digital isolator 121 has high isolation voltage and strong anti-interference ability, and the transceiver 122 provides flexible signal conversion and transmission capability.

[0042] By realizing the isolation between different parts of the circuit, electromagnetic interference, electromagnetic pulses and other adverse factors are effectively avoided, providing a strong guarantee for the stable operation of the circuit.

[0043] The isolation module 120 realizes electrical isolation and signal transmission between the main control module 110 and the controlled device 300 through the cooperative work of the digital isolator 121 and the transceiver 122, ensuring the safety and stability of the entire data communication converter.

[0044] Further, the transceiver 122 is an RS-422 transceiver 122, and the signal transmission interface is a URAT interface.

[0045] The transceiver 122 in the isolation module 120 adopts the RS-422 standard, which can realize long-distance and high-rate data transmission. Among them, the RS-422 transceiver 122 converts the signal transmitted by the digital isolator 121 into a differential signal, which is transmitted through a balanced twisted pair line, and has good anti-interference ability and long-distance transmission characteristics.

[0046] The URAT interface is a universal asynchronous receive-transmit serial port, which is used to realize serial transmission of data. The URAT interface converts the parallel data of the main control module 110 into a serial data stream, which is transmitted to the controlled device 300 through the digital isolator 121 and the RS-422 transceiver 122. The isolation module 120 using the RS-422 transceiver 122 can provide high-speed and long-distance data transmission while maintaining the integrity of the signal and the stability of the system. The RS-422 standard allows multiple receiving nodes to be connected on the same transmission line, with a maximum of 10 nodes, which makes it very useful in application scenarios that require multipoint communication.

[0047] The isolation module 120 realizes electrical isolation and signal transmission between the main control module 110 and the controlled device 300 through the combination of the digital isolator 121 and the RS-422 transceiver 122, ensuring the safety and reliability of the data communication converter. At the same time, the URAT interface as the starting point of signal transmission completes the serialization process of data, providing a foundation for subsequent isolation and transmission.

[0048] The lighting end of the iPhone transmits USB signals to the processor 111 through the USB interface. The USB signals are output as UART signals by the processor 111 and transmitted to the RS-422 transceiver 122 under the action of the digital isolator 121. The RS-422 transceiver 122 converts the UART signals into 422 signals under a 5V working voltage. Conversely, the RS-422 transceiver 122 converts 422 signals into UART signals and transmits the data back to the processor 111 through the digital isolator 121. The UART signals are output as USB signals by the processor 111 and connected to the lighting end of the iPhone through the USB interface to realize data communication. Thus, data transmission between the lighting end of the iPhone and the RS-422 transceiver 122 is realized.

[0049] Further, the isolation module 120 further comprises an optoelectronic coupler 123, which is electrically connected to the processor 111.

[0050] In this embodiment, the optoelectronic coupler 123 is a semiconductor optoelectronic device that transmits electrical signals through electro-optical-electro conversion. In the isolation module 120, the optoelectronic coupler 123 is electrically connected to the processor 111 to realize electrical isolation between the input and output circuits. Such isolation is crucial for protecting sensitive circuits, preventing high-voltage spikes, and eliminating electrical noise in signals.

[0051] The working principle of the optoelectronic coupler 123 is based on the photoelectric effect and the characteristics of PN junctions. When current passes through a light-emitting diode (LED), the LED emits light signals that are received by a photosensitive element (such as a photosensitive triode) packaged in the same housing and converted into electrical signals. Since the input and output ends transmit signals through light signals, the two parts are completely electrically isolated, with no feedback and interference of electrical signals, thereby providing stable performance and strong anti-interference ability.

[0052] As Figure 4As shown, the isolation module 120 is equipped with a power module, which can be used to protect the processor 111 from high voltage or current surges. The power module provides two voltage outputs: VIA and VOB. These two voltages are used for different circuit parts. CURX and MCUTX represent the receive and transmit pins of the processor 111, respectively, for serial communication. C19 is a decoupling capacitor used to stabilize the voltage of the MCUTX pin. Isolation chip U4, SP3400 is a four-channel digital isolator 121 used to provide electrical isolation between different circuits while allowing digital signals to pass through. The VCC pin provides power for the isolator, and the GND pin is grounded. The A, B, C, D pins are input terminals, corresponding to the Y, Z, W, X pins on the other side of the isolator as output terminals. R15, R23, R32, R34, R35 are current limiting resistors used to protect the circuit and control the current. C17 is a decoupling capacitor used to stabilize the power pin of the isolation chip. Optocoupler U2, HCPL-316J is a high-speed optocoupler used to provide electrical isolation between circuits. The input side of the optocoupler is the LED part, connected to the output of the isolation chip through resistors R13, R18, R20, R21. The output side is the phototransistor part, connected to the ground through resistors R17, R22, forming a current loop. Filter F1, 22uH is an inductive filter used to suppress electromagnetic interference and protect the circuit from high-frequency noise. Connector PG is a programming or debugging interface used to connect with external devices. D2 is a transient voltage suppression diode TVS used to protect the circuit from voltage spikes.

[0053] Overall, the isolation part containing the digital isolator 121 and the optocoupler is used to provide electrical isolation between the processor 111 and external circuits while allowing digital signals to pass through. This design can improve the safety and reliability of the system, preventing damage to the processor 111 caused by high voltage or current.

[0054] As Figure 5As shown, the main control module 110 is equipped with a power management circuit, which converts the input voltage to a stable output voltage and provides the required voltage for different devices. Among them, F1 is a self-resetting fuse for overcurrent protection. When the current exceeds the set value, F1 will disconnect the circuit to protect the subsequent circuit from damage. Voltage regulator U2, DS90C282 is a low dropout linear regulator LDO that converts the input voltage VIN to a stable 3.3V output voltage VOUT. The EN pin is used to enable or disable the regulator. When the EN pin is grounded, the regulator is enabled; when the EN pin is floating or connected to a high level, the regulator is disabled. C6 and C7 are bypass capacitors that reduce power supply noise and ensure the stability of the output voltage. C8 is an output capacitor that further smooths the output voltage and reduces ripple. TP_PV3 is a test point for measuring the output voltage of the regulator, facilitating debugging and testing. P1 is an I2C interface for communication with the processor 111. I2C is a commonly used serial communication protocol for connecting multiple devices. R9 and R10 are pull-up resistors that ensure the I2C bus is at a high level when idle. SW1 is a switch that controls the on-off of the circuit. When SW1 is closed, the circuit is on; when SW1 is open, the circuit is off. Connector Header 4 is a 4-pin connector for connecting external devices or circuits. +3.3V and GND provide 3.3V power and ground, respectively. R8 is a current-limiting resistor that limits the current flowing through SW1, protecting the switch and circuit. The input voltage is converted to a stable 3.3V output by the regulator, and communication with external devices is achieved through the I2C interface. At the same time, the circuit also contains overcurrent protection and switch control functions, ensuring the safety and flexibility of the circuit.

[0055] The isolation module 120 includes digital isolation circuit, optoelectronic coupling circuit, not only can effectively isolate power, also makes the signal without modulation and demodulation can transmit signal. Power module mainly for DS8562 power conversion circuit, can convert 5V voltage to 3.3V voltage, to each part of the circuit power supply.

[0056] The converter circuit works as follows: under the action of the DS8562 power conversion chip, 5V power is converted into 3.3V power, thereby supplying power to the processor 111 and the MFI authentication module 112. The processor 111 performs I2C data transmission with the MFI authentication chip, so as to authenticate the MFI authentication chip, and after authentication, iap2 communication can be established with the iphone mobile phone. The lighting end of the iphone mobile phone transmits usb signals to the processor 111 through the USB interface, the usb signals are output as UART signals by the processor 111, and under the action of the digital isolator 121, the UART signals are transmitted to the RS-422 transceiver 122. The RS-422 transceiver 122 converts the UART signals into 422 signals under the action of a 5V working voltage. Conversely, under the action of the RS-422 transceiver 122, the 422 signals are converted into UART signals and transmitted back to the processor 111 through the digital isolator 121. The UART signals are output as usb signals by the processor 111, and are connected with the lighting end of the iphone mobile phone through the USB interface to realize data communication. In this way, data transmission between the lighting end of the iphone mobile phone and the RS-422 transceiver 122 is realized.
