Abstract
Description
Technical Field
[0001] The present invention relates to the field of communication circuits, and more specifically, to a hub communication transparent transmission circuit and device that can be instantaneously configured based on a USB interface and is compatible with multiple devices. Background Art
[0002] In the context of current technological development, with the rapid development of fields such as the Internet of Things (IoT), industrial automation, smart home, and cloud computing, communication and interconnection between devices have become an essential and crucial link in building an efficient and intelligent system. However, although this trend has greatly promoted technological integration and innovation, the interface differences and protocol incompatibility issues among different devices have become increasingly prominent, becoming a major obstacle restricting the overall performance improvement of the system and efficient data processing.
[0003] Specifically, there are numerous devices on the market with different brands and models, which are often developed based on different technical standards and design concepts, resulting in a variety of interface types. From traditional serial interfaces (such as RS-232, RS-485) to modern USB, Ethernet, Wi-Fi, Bluetooth, and even more advanced wireless communication technologies such as LoRa and NB-IoT, each interface has its specific application scenarios and advantages, but at the same time, it also increases the complexity of direct communication between devices. In addition, even devices using the same interface may not be able to directly exchange data because they follow different communication protocols (such as Modbus, Profinet, OPC UA, etc.), which further exacerbates the data island phenomenon.
[0004] This inconsistency in interfaces and protocols not only increases the difficulty and cost of device access to the system but also limits the real-time, accurate, and complete nature of data. For systems that need to process data from multiple sources (such as intelligent manufacturing factories, smart city management systems, etc.), seamless integration and efficient processing of data between different devices become particularly crucial. However, due to the above-mentioned obstacles, data may face problems such as delay, loss, and format mismatch during transmission, seriously affecting the decision-making efficiency and response speed of the system.
[0005] Therefore, developing a solution that can achieve efficient communication and data interaction between devices across interfaces and protocols has become an urgent need in the current technical field. This solution needs to be able to automatically identify and adapt to the interfaces and protocols of different devices, achieve unified format conversion and efficient transmission of data, and at the same time ensure the security, integrity, and real-time nature of data. Through such technological innovation, the barriers between devices can be effectively broken, promoting the deep integration and application of data resources, and providing strong support for building a more intelligent and collaborative system. Summary of the Invention
[0006] The present invention aims to overcome at least one defect in the prior art, and provides a hub communication transparent transmission circuit and device based on USB interface instant configuration and compatible with multiple devices, which are used to solve the problems of delay, loss, and format mismatch encountered in the data transmission process between different devices.
[0007] The technical solution adopted by the present invention is a hub communication transparent transmission circuit based on USB interface instant configuration and compatible with multiple devices, including:
[0008] A USB interface integration module, which is used to realize the data integration and conversion of multiple devices;
[0009] A USB module, which is connected to the USB interface integration module and is used to realize the configuration of multiple devices and upload data;
[0010] Multiple device interface terminals, which are used to connect with multiple devices and receive data;
[0011] A storage module, which is connected to the USB interface integration module and is used to store the running control program and data;
[0012] A power supply module, which is connected to the USB interface integration module and is used to supply power to each of the above modules;
[0013] It further includes multiple data board interface corresponding to the number of device interface terminals. Each data board interface includes a separately arranged input end and output end. The input end is connected to the device interface terminal and is used to receive the uploaded data, and the output end is connected to the USB interface integration module and is used to output the uploaded data to the USB interface integration module. By introducing the same number of device interface terminals and data board interfaces, and each interface includes a separately arranged input end and output end, the data board interface has flexibility and scalability. The hub can flexibly configure the data board to adapt to the access of multiple numbers and types of devices, broaden the applicable range of the hub, and improve the compatibility of the devices. Additionally, as one of the core components of the hub, the USB module is not only responsible for realizing the configuration management of multiple devices, but also responsible for uploading device data to the USB interface integration module. Through the instant configuration function, the administrator can flexibly set the parameters and communication protocols of the devices to ensure seamless docking between the devices.
[0014] To make the voltage input from the data board interface to the USB interface integration module a fixed voltage, each data board interface includes an input terminal and several output terminals, and also includes a voltage conversion module. After several output terminals are connected to the voltage conversion module and then to the USB interface integration module, different output terminals correspond to different input voltages. Different input voltages are input to the input terminal of the data board interface, output from the corresponding output terminal to the voltage conversion module, converted into a fixed voltage, and then input to the USB interface integration module to ensure the normal operation of the USB interface integration module.
[0015] The input terminal and the output terminal adopt the PZ254V pin header structure, the device interface terminal adopts the WJ15EDGRC pluggable wiring terminal, the output terminal includes two, corresponding to the 5V and 3V input voltages respectively, and the voltage conversion module is the TXS0108EPWR chip.
[0016] To efficiently and stably transmit the data received from the device interface terminal, the hub communication transparent transmission circuit based on USB interface instant configuration and compatible with multiple devices also includes multiple data processing boards for processing multiple different devices. The data processing boards are respectively connected to the input terminal and the output terminal of the data board interface. The input terminal receives the uploaded data, and after being processed by the corresponding data processing board, it is output to the USB interface integration module. The input terminal serves as the entry point of the data stream and is responsible for receiving the uploaded data from external devices or systems. These data are then guided to the corresponding data processing boards through a high-speed and low-latency internal transmission path for a series of complex data processing operations including but not limited to data parsing, encoding, encryption, compression, or any specific algorithm processing. The processed data is transmitted to the output terminal for further transmission or storage. The USB interface integration module outputs the processed data to the external storage module efficiently and stably in the standard USB protocol format and performs data integration and conversion.
[0017] To ensure the integrity and security of data transmission, the data processing board is connected to the input terminal and the output terminal of the data board interface through a pluggable cable. The cable is designed with docking terminals that can match and firmly connect the input terminal and the output terminal of the data board interface, which not only simplifies the installation and maintenance process but also significantly improves the stability and efficiency of data transmission. The pluggable cable is made of high-reliability materials and has characteristics such as wear resistance and strong anti-interference ability, ensuring the integrity and security during data transmission. In addition, this design allows for the quick replacement or upgrade of the data processing board without interrupting the operation of other parts of the system, greatly enhancing the flexibility and scalability of the system.
[0018] To improve the transmission efficiency and flexibility of data from the device interface terminals to the USB interface integration module, which includes four device interface terminals, the USB interface integration module uses the FT4232HL chip. The four data board interfaces corresponding to the four device interface terminals are connected to the UART1, UART2, UART3, and UART4 interfaces of the FT4232HL chip. The FT4232HL chip, as a communication interface chip integrating multiple universal asynchronous receiver / transmitters, each of its UART interfaces has independent communication capabilities, supports full-duplex or half-duplex communication modes, and can be configured with different baud rates and communication protocols as needed. In the present invention, the UART1, UART2, UART3, and UART4 interfaces of the FT4232HL chip independently receive data streams from their respective corresponding data board interfaces, realizing the ability of multi-channel parallel data processing and greatly improving the efficiency and flexibility of data communication.
[0019] To ensure the normal operation of the USB interface integration module, the hub communication transparent transmission circuit based on USB interface instant configuration and compatible with multiple devices further includes a watchdog module, and the power supply module further includes a reset module. The watchdog module and the reset module are connected to the USB interface integration module to monitor the operation of the USB interface integration module and reset the USB interface integration module in case of errors.
[0020] To visually display the usage situation of the system and the device access situation, the present invention provides a hub communication transparent transmission device based on USB interface instant configuration and compatible with multiple devices, including a housing, the above-mentioned hub communication transparent transmission circuit based on USB interface instant configuration and compatible with multiple devices, device indicators, and USB indicators. The hub communication transparent transmission circuit is installed inside the housing, and the device indicators and USB indicators are exposed outside the housing and connected to the USB interface integration module to indicate the connection situation of the devices. The USB module and the device interface terminals are also partially exposed outside the housing, and a fixing bracket for the data processing board is provided inside the housing. When a device is connected to the system, the corresponding device indicator lights up, indicating that a device is connected. When the system is running, the USB indicator lights up, indicating that the system is operating.
[0021] The housing is in the shape of a rectangular box. The USB module, device indicators, and USB indicators are set on one side of the housing, and the device interface terminals are set on the other side. And each device interface terminal and its corresponding device indicator are arranged in the same order. The fixing bracket is set above the hub communication transparent transmission circuit.
[0022] To facilitate the installation and disassembly of the system, an installation bracket is provided on one side of the housing, and a detachable cover plate is provided on the other side. When the system fails or needs to be repaired, the cover plate can be opened for inspection and repair.
[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0024] The data board interface has flexibility and scalability. The present invention introduces a plurality of data board interfaces corresponding to the number of device interface terminals, and each interface includes a separately arranged input end and an output end. This design enables the hub to flexibly configure data boards according to actual needs to adapt to the access of devices with different numbers and types. Through the design of the USB interface integration module and multiple device interface terminals, data integration and conversion of various different types of devices are achieved. This means that regardless of the interface or protocol of the devices, as long as they can be connected to the device interface terminals through appropriate adapters or conversion cables, they can all be recognized by the hub and accessed into the system. By combining different chips into various modules, the type of USB device connected to the system can be recognized, and the communication protocol and parameter settings can be adjusted to the optimal state, ensuring that each device can obtain the best data transmission effect and reducing the risk of data transmission errors or interruptions caused by improper configuration; through the four channels of the data board interface connecting the USB interface integration module, multi-channel parallel processing is achieved. Even when multiple devices are connected simultaneously, it can ensure that there is no interference between channels, and each channel can independently and efficiently complete the data transmission task, greatly improving the reliability of data transmission. By optimizing the transmission path, stable transmission of USB signals over a longer distance is achieved. For application scenarios that require spanning a large space or a complex environment, the system can ensure the effective coverage and high-quality transmission of USB signals, realizing stable transmission of long-distance data. This design greatly broadens the applicable range of the hub and improves the compatibility of devices. The USB module, as one of the core components of the hub, is not only responsible for implementing the configuration management of various devices but also for uploading device data to the USB interface integration module. Through the instant configuration function, the administrator can flexibly set the parameters and communication protocols of the devices to ensure seamless docking between devices.
[0025] In summary, through the integrated USB interface design, flexible data board interface configuration, and intelligent data processing functions, the technical solution effectively solves the problems of interface incompatibility and data transmission obstacles in the communication and interconnection of existing devices. It not only improves the compatibility of devices and the flexibility of the system but also realizes efficient data transmission and intelligent processing, providing strong support for building a more intelligent and collaborative system.

The USB interface integration module is also connected to the watchdog module and the reset module of the power module. The watchdog module is used to monitor the operation of the USB interface integration module. When the watchdog module detects that the USB interface integration module runs erratically, the reset module will reset the USB interface integration module. The USB interface integration module is connected to the LED indicator light.

The number of device interface terminals is the same as that of the data board interface.
[0041] As Figure 2 shown in the figure, this embodiment also provides a hub communication transparent transmission based on USB interface instant configuration and compatible with multiple devices, including a housing 100. The interior of the housing 100 is configured with the above-mentioned USB interface integration module, USB module, data board interface and storage module. The exterior of the housing 100 is provided with a USB indicator light and device indicator lights.

The USB module and the device interface terminals are also partially exposed outside the housing. A fixed bracket for the data processing board card is provided inside the housing 100.
[0042] As Figure 3 shown in the figure, the storage module of this embodiment is composed of a chip M93C56 - RMN6TP. M93C56 - RMN6TP is a semiconductor of STMicroelectronics and is used to store the allowed control programs and data.
[0043] As Figure 4As shown, the USB interface integration module of this embodiment is composed of an FT4232HL chip. The FT4232HL is a highly integrated USB-to-serial converter with four interfaces, and each interface can be independently configured as an asynchronous or synchronous, serial or parallel FIFO interface. These interfaces are based on USB 2.0 High Speed (480 Mb / s) technology and support high-speed data transmission.
[0044] As Figure 5 shown, the four UART interfaces of the FT4232HL USB interface integration module of this embodiment are UART1, UART2, UART3, and UART4 respectively. Each interface can be configured with different serial communication protocols. Two of the interfaces can be configured as UART, JTAG, SPI, I2C, or a bit response mode serial port with an independent baud rate generator, and the other two interfaces have UART functions or bit response functions.
[0045] As Figure 6 shown, the USB module of this embodiment includes components such as a USB connector USB-226-BRW, a TVS diode SP0503BAHTG, and a diode LED. The USB-226-BRW is connected to the SP0503BAHTG and the LED lamp components. The SP0503BAHTG is a surface-mounted array series for suppressing ESD and other transient overvoltage events to meet international electrical compatibility. These components can help protect sensitive digital or analog input circuits on data, signal, or control lines with a voltage level up to 5 VDC; the LED lamp is used to indicate the access situation of the USB module by the user. When the USB module is connected to the USB interface integration module, the USB indicator light outside the housing 100 lights up. In addition, as one of the core components of the hub, the USB module is not only responsible for implementing the configuration management of multiple devices but also for uploading device data to the USB interface integration module. Through the instant configuration function, the administrator can flexibly set the parameters and communication protocols of the devices to ensure seamless docking between devices.
[0046] As Figure 7As shown in the figure, the voltage conversion module of this embodiment is composed of the chip TXS0108EPWR. The data board interface is connected to TXS0108EPWR and then integrated with the USB interface module. TXS0108EPWR is an 8-bit non-inverting converter chip with two independent configurable power rails; Port A is used to track the power supply voltage of the VCCA pin, and the VCCA pin accepts a power supply voltage of 1.2 to 3.6V. Port B is used to track the power supply voltage of the VCCB pin, and the VCCB pin accepts any power supply voltage between 1.65V and 5.5V. The VCCA and VCCB pins allow low-voltage bi-directional conversion of 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. Different input voltages are input to the input end of the data board interface, output from the corresponding output end to the voltage conversion module, converted into a fixed voltage, and then input to the USB interface integration module to ensure the normal operation of the USB interface integration module.
[0047] As Figure 8 shown in the figure, the data board interface of this embodiment includes an input end and two output ends. Both the input end and the output end are composed of the PZ254V pin header structure. The output ends correspond to the 5V and 3V input voltages respectively. The input end is connected to the device interface terminal, and the output end is connected to the voltage conversion module. After the voltage is converted by the voltage conversion module, it is connected to the USB interface integration module. Data is transmitted from the device interface terminal to the USB interface integration module to complete the data integration and conversion of multiple devices.
[0048] Additionally, this embodiment further includes multiple data processing boards (not labeled in the figure) for processing multiple different devices. The data processing boards are respectively connected to the input end and the output end of the data board interface. The input end receives the uploaded data, and after being processed by the corresponding data processing board, it is then output to the USB interface integration module. The input end serves as the entry point of the data stream and is responsible for receiving the uploaded data from external devices or systems. These data are then guided to the corresponding data processing boards through high-speed and low-latency internal transmission paths for a series of complex data processing operations including but not limited to data parsing, encoding, encryption, compression, or any specific algorithm processing. The processed data is transmitted to the output end and is ready for the next step of transmission or storage. The USB interface integration module efficiently and stably outputs the processed data to the external storage module in the standard USB protocol format and also performs data integration and conversion. To ensure the integrity and security of data transmission, the data processing board is connected to the input end and the output end of the data board interface through a pluggable cable. This cable is designed with docking terminals that can match and firmly connect the input end and the output end of the data board interface, not only simplifying the installation and maintenance processes but also significantly enhancing the stability and efficiency of data transmission. The pluggable cable is made of high-reliability materials and has characteristics such as wear resistance and strong anti-interference ability, ensuring the integrity and security during the data transmission process. In addition, this design allows for the quick replacement or upgrade of the data processing board without interrupting the operation of other parts of the system, greatly enhancing the flexibility and scalability of the system.
[0049] As Figure 9 shown, the device interface terminals of this embodiment adopt WJ15EDGRC pluggable wiring terminals. The 4 pins of the WJ15EDGRC pluggable wiring terminals are connected to the 4 pins of PZ254V at the input end of the data board interface. The number of device interface terminals corresponds to the data board interface. Through the same number of device interface terminals and data board interfaces, and each interface includes separately set input and output ends, the data board interface has flexibility and scalability. The hub can flexibly configure the data board to adapt to the access of multiple numbers and types of devices, broadening the applicable range of the hub and improving the device compatibility.
[0050] As Figure 10 shown, this embodiment has 4 device indicators, which respectively correspond to different channels. When the device is connected to the USB interface integration module through modules such as device interface terminals, when the accessed pin is UART_TX, the indicator is green, and when the accessed pin is UART_RX, the indicator is red, which is used to indicate the access situation of the user device.
[0051] As Figure 11As shown, the system indicator light of this embodiment is used to indicate the operation status of the user system and visually feedback to the user with green and red lights.
