背景技术Background technique
随着工业电子设备对数据交换速度的要求越来越高，越来越多的工业设备也开始As industrial electronic equipment has higher and higher requirements for data exchange speed, more and more industrial equipment has also begun to
使用 USB 接口，对通讯的可靠性要求也越来越高。 但现有的 USB 通讯电路对抗运行环境干扰的能力差，极易受到工业环境中的静电与电磁波干扰，而且由于工业环境的复杂性，主机端和设备端接口电平可能不同，连接后可能使两侧的设备都无法正常工作，并且任一侧的干扰会沿着 USB 接口传递到主机 / 设备端，容易对整个系统造成严重损坏，目前在国内外广泛使用的电源与信号隔离保护装置主要分为三种 ：光电隔离式，变压器隔离式，电容隔离式。With the USB interface, the requirements for the reliability of the communication are getting higher and higher. However, the existing USB communication circuit has poor ability to resist the interference of the operating environment, and is extremely susceptible to static electricity and electromagnetic wave interference in the industrial environment. Moreover, due to the complexity of the industrial environment, the interface levels of the host end and the device end may be different. The equipment on both sides cannot work normally, and the interference on either side will be transmitted to the host/device side along the USB interface, which will easily cause serious damage to the entire system. The power supply and signal isolation protection devices widely used at home and abroad are mainly divided into There are three types: photoelectric isolation, transformer isolation, and capacitive isolation.
目前，国外有几家半导体公司对于 USB2.0 信号的隔离提供了解决方案，但是售价高昂，方案设计复杂，极难推广到实际应用。 而且，随着 USB3.0对传输速度进行了大幅提升，它基于全双工数据传输协议，理论传输速率高达5Gbps(即625MB/秒)，实际数据传输速率也将高达3.2Gbps (即400MB/秒)，相比USB2.0时代有了将近10倍的提升，而现在最新的USB3.1 Gen2标准又将传输速率提升到了10Gbps，因此数据的传输距离遇到了前所未有的挑战。At present, several foreign semiconductor companies have provided solutions for the isolation of USB2.0 signals, but the price is high, the design of the scheme is complicated, and it is extremely difficult to promote it to practical applications. Moreover, with USB3.0 greatly improving the transmission speed, it is based on the full-duplex data transmission protocol, the theoretical transmission rate is as high as 5Gbps (ie 625MB/s), and the actual data transmission rate will also be as high as 3.2Gbps (ie 400MB/s ), compared with the USB2.0 era, it has been improved by nearly 10 times, and now the latest USB3.1 Gen2 standard has increased the transmission rate to 10Gbps, so the data transmission distance has encountered unprecedented challenges.
如中国专利申请号201410572419.4，提供一种全速 USB3.0 接口隔离保护装置，这种装置的变压器隔离相比光电隔离，虽然传输速度提升到了5Gbps，但是由于采用了电感元件，存在着电压互感耦合的风险，并不能完全的实现医疗领域要求的安全隔离度。For example, Chinese patent application number 201410572419.4 provides a full-speed USB3.0 interface isolation protection device. Compared with photoelectric isolation, the transformer isolation of this device has a transmission speed of 5Gbps, but due to the use of inductive components, there is a problem of voltage mutual inductance coupling. Risk, and cannot fully realize the safety isolation required by the medical field.
在医疗领域往往因为安全考虑，需要将测量设备与计算机之间进行4000V的电气隔离，以往USB2.0、USB3.0还可以采用一些变压器进行耦合隔离，但是随着传输速率提升到了5Gbps~10Gbps，采用传统的变压器耦合隔离方案已无法适应5Gbps~10Gbps的传输，而且变压器耦合在电气隔离上面还是存在一定缺陷，电气隔离不如光电耦合方式和微波耦合方式，光电耦合方式和微波耦合方式这两种方式都可以实现电气的完全隔离，但是光电耦合方式速率较慢，一般只能在12Mbps。在微波通信领域，频率范围在30-300GHz频段内，波长短于超高频(SHF)的电磁波信号，我称之为极高频 EHF (Extremely High Frequency) ，波长由1mm到10mm，主要应用于气象雷达、空间通信、射电天文等方面。In the medical field, due to safety considerations, 4000V electrical isolation between the measuring device and the computer is required. In the past, USB2.0 and USB3.0 can use some transformers for coupling isolation, but as the transmission rate increases to 5Gbps~10Gbps, The traditional transformer coupling isolation scheme can no longer adapt to the transmission of 5Gbps~10Gbps, and the transformer coupling still has some defects in the electrical isolation. The electrical isolation is not as good as the photoelectric coupling method and the microwave coupling method. The photoelectric coupling method and the microwave coupling method Both can achieve complete electrical isolation, but the speed of photoelectric coupling is relatively slow, generally only 12Mbps. In the field of microwave communication, the frequency range is in the 30-300GHz frequency band, and the wavelength is shorter than the SHF electromagnetic wave signal. I call it EHF (Extremely High Frequency), and the wavelength is from 1mm to 10mm. It is mainly used in Weather radar, space communication, radio astronomy, etc.

所述一种对USB3.0微波发送端和USB3.0微波接收端之间微波通信的自动协商方法，是指通过单片机编程技术和制定相关的通信规则来解决在使用微波传输USB3.0数据过程中因USB3.0微波发送端和USB3.0微波接收端相互分离、计算机开关机及重启后USB3.0终端设备重新计算机主机建立正确通信链接的方法。The described automatic negotiation method for microwave communication between the USB3.0 microwave sending end and the USB3.0 microwave receiving end refers to solving the problem of using microwave to transmit USB3. Because the USB3.0 microwave transmitting end and the USB3.0 microwave receiving end are separated from each other, the USB3.0 terminal equipment and the computer host are re-established to establish a correct communication link after the computer is switched on and off and restarted.
USB3.0微波通信是一个全双工双向通信，如果因USB3.0微波发送端和USB3.0微波接收端相互分离，计算机主机与远端USB3.0微波接收端的USB3.0 HUB主控芯片需要重新建立连接，此时双方会重新发起低速LFPS信号进行握手连接，从而确定连接状态，但此时如果USB3.0微波接收端的USB3.0 HUB主控芯片还未退出超高速链接状态， USB3.0微波发送端连接的USB3.0主控制器收到的不是LFPS数据信号，而是超高速数据包，这样就会导致协商失败，导致计算机连接此USB3.0微波发送端的USB3.0主控制器端口死机，从而无法识别USB3.0微波接收端的USB3.0 HUB主控芯片及外接USB3.0终端设备。 USB3.0 microwave communication is a full-duplex two-way communication. If the USB3.0 microwave transmitter and USB3.0 microwave receiver are separated from each other, the host computer and the USB3.0 HUB master chip of the remote USB3.0 microwave receiver need to Re-establish the connection. At this time, the two parties will re-initiate the low-speed LFPS signal for handshake connection to determine the connection status. But at this time, if the USB3.0 HUB main control chip at the USB3.0 microwave receiving end The USB3.0 host controller connected to the microwave transmitter does not receive the LFPS data signal, but the ultra-high-speed data packet, which will cause the negotiation to fail, causing the computer to connect to the USB3.0 host controller port of the USB3.0 microwave transmitter Crash, thus unable to recognize the USB3.0 HUB main control chip of the USB3.0 microwave receiving end and the external USB3.0 terminal equipment.
USB3.0微波发送端和USB3.0微波接收端在通信过程中往往会遇到计算机主机关机、重启、计算机主机关机了很长时间后重新开机，这样就会面临严峻的问题：当计算机主机重新进入操作系统后，经常会出现USB3.0微波发送端和USB3.0微波接收端与当计算机主机连接失败，计算机主机有可能会提示USB3.0设备合规但是无法链接、或是根本没有链接动作，导致这个问题的原因是在计算机主机退出系统后，USB3.0微波发送端和USB3.0微波接收端的通信状态并未进入LFPS协商状态，而一直处于正常的超高速链接状态，当计算机主机重新进入系统后，计算机主机的USB3.0主控制器本应该与USB3.0微波接收端是一个低速率通信模式，但实际计算机主机的USB3.0主控制器首先收到的是USB3.0微波发送端发送过来的超高速数据包，从而导致两者的协商失败，从而计算机主机无法找到USB3.0主控制器外接的所有USB3.0终端设备。USB3.0 microwave transmitting end and USB3.0 microwave receiving end often encounter computer host shutting down, restarting, computer host shutting down for a long time and then restarting in the communication process, which will face severe problems: when the computer host restarts After entering the operating system, it often occurs that the USB3.0 microwave transmitter and USB3.0 microwave receiver fail to connect to the host computer, and the host computer may prompt that the USB3.0 device is compliant but cannot be connected, or there is no link action at all. , the cause of this problem is that after the host computer exits the system, the communication status of the USB3.0 microwave transmitter and USB3.0 microwave receiver has not entered the LFPS negotiation state, but has been in the normal ultra-high-speed link state. When the host computer restarts After entering the system, the USB3.0 main controller of the host computer should be in a low-speed communication mode with the USB3.0 microwave receiving end, but the USB3.0 main controller of the actual computer host first receives the USB3.0 microwave sending end. The ultra-high-speed data packets sent from the end, resulting in the failure of the negotiation between the two, so that the host computer cannot find all the USB3.0 terminal devices externally connected to the USB3.0 host controller.
本发明在此约定一种用于USB3.0微波发送端和USB3.0微波接收端之间微波通信的自动协商方法，如下1-6项所示。The present invention specifies an automatic negotiation method for microwave communication between a USB3.0 microwave sending end and a USB3.0 microwave receiving end, as shown in items 1-6 below.
1.不管任何时候，USB3.0微波发送端的微波信号接收机总是先于USB3.0微波接收端的微波信号接收机收到微波信号；USB3.0微波发送端的微波信号接收机在连接中断后,MCU控制单元发输出控制指令使USB3.0微波发送端的微波信号发送机一直处于禁止发射状态，USB3.0微波接收端的微波信号接收机收不到微波信号后输出一个低电平状态指示信号Receive Ready到接收端MCU控制单元的RX_RDY输入引脚，MCU控制单元发输出控制指令使USB3.0 HUB主控芯片上行接口链路断开，USB3.0 HUB主控芯片进入待机状态，保证USB3.0HUB主控芯片不会发送超高速数据包出来，但USB3.0微波接收端的微波信号发送机一直处于发射状态。1. At any time, the microwave signal receiver at the USB3.0 microwave sending end always receives the microwave signal before the microwave signal receiver at the USB3.0 microwave receiving end; after the connection is interrupted, the microwave signal receiver at the USB3.0 microwave sending end The MCU control unit sends an output control command so that the microwave signal transmitter at the USB3.0 microwave transmitting end is always in the state of prohibiting transmission, and the microwave signal receiver at the USB3.0 microwave receiving end fails to receive the microwave signal and outputs a low-level status indicating signal Receive Ready To the RX_RDY input pin of the MCU control unit at the receiving end, the MCU control unit sends an output control command to disconnect the uplink interface link of the USB3.0 HUB main control chip, and the USB3.0 HUB main control chip enters the standby state to ensure that the USB3.0 HUB main control chip The control chip will not send out ultra-high-speed data packets, but the microwave signal transmitter at the USB3.0 microwave receiving end is always in the transmitting state.
2.USB3.0微波发送端和USB3.0微波接收端分离开后，两者的物理连接侦测电路发出控制信号，使USB3.0微波发送端和USB3.0微波接收端都处于掉电状态，MCU控制单元根据侦测电路的输出信号发输出控制指令使USB3.0微波发送端USB3.0上行接口与计算机主机的USB3.0主控制器链路连接中断。2.

After the USB3.0 microwave transmitter and USB3.0 microwave receiver are separated, the physical connection detection circuit of the two sends out a control signal, so that both the USB3.0 microwave transmitter and USB3.0 microwave receiver are in a power-off state , the MCU control unit sends an output control command according to the output signal of the detection circuit to interrupt the link connection between the USB3.0 uplink interface 11 of the USB3.0 microwave transmitting end and the USB3.0 main controller 1 of the computer host.
3. 当USB3.0微波发送端和USB3.0微波接收端重新建立物理连接后，两者的物理连接侦测电路发出控制信号，使USB3.0微波发送端和USB3.0微波接收端都处于上电状态，USB3.0微波发送端的微波信号接收机132收到USB3.0微波接收端发过来的微波信号，微波信号接收机132发出一个状态指示信号Receive Ready到发送端MCU控制单元14的RX_RDY输入引脚1415，MCU控制单元14发出控制信号使能USB3.0微波发送端的微波信号发送机131，USB3.0微波发送端的微波信号发送机131向USB3.0微波接收端发送链路初始化信号，USB3.0微波接收端的微波信号接收机232收到微波信号后输出一个高电平状态指示信号Receive Ready到接收端MCU控制单元的RX_RDY输入引脚2415，MCU控制单元24向USB3.0HUB主控芯片22发出VBUS_DET使能信号，从而USB3.0 HUB主控芯22片进入在线连接状态，当USB3.0 HUB主控芯片22收到计算机主机USB3.0主控芯片1发送来的LFPS协商信号后，会向计算机主机USB3.0主控芯片1返回相应LFPS协商信号，直至链路连接成功。3. When the USB3.0 microwave transmitter and the USB3.0 microwave receiver re-establish the physical connection, the physical connection detection circuit of the two sends out a control signal, so that both the USB3.0 microwave transmitter and the USB3.0 microwave receiver are in the In the power-on state, the microwave signal receiver 132 of the USB3.0 microwave transmitting end receives the microwave signal sent by the USB3.0 microwave receiving end, and the microwave signal receiver 132 sends a status indication signal Receive Ready to the RX_RDY of the MCU control unit 14 of the transmitting end The input pin 1415, the MCU control unit 14 sends a control signal to enable the microwave signal transmitter 131 of the USB3.0 microwave sending end, and the microwave signal transmitter 131 of the USB3.0 microwave sending end sends a link initialization signal to the USB3.0 microwave receiving end, The microwave signal receiver 232 of the USB3.0 microwave receiving end outputs a high-level status indicator signal Receive Ready to the RX_RDY input pin 2415 of the MCU control unit at the receiving end after receiving the microwave signal, and the MCU control unit 24 sends a signal to the USB3.0HUB main control chip 22 sends a VBUS_DET enable signal, so that 22 USB3.0 HUB main control chips enter the online connection state.

4. 在采用外部电源供电时，如果USB3.0微波发送端与计算机主机USB3.0主控芯片1的数据线拔除后，USB3.0微波发送端的MCU控制单元14向供电单元18发出指令，使发送端的微波信号发送机131处于禁止发射状态，同时切断USB3.0微波接收端的电源，减少电源消耗；当连接计算机主机的数据线重新连接好，并且计算机主机处于开机状态，USB3.0端口供电正常的情况下，USB3.0微波发送端的MCU控制单元14向供电单元18发出指令，恢复USB3.0微波接收端的电源供应，USB3.0微波接收端的微波信号发送机232发出链路初始化信号。4. When the external power supply is used, if the data line between the USB3.0 microwave transmitting end and the USB3.0 main control chip 1 of the host computer is unplugged, the MCU control unit 14 of the USB3.0 microwave transmitting end sends an instruction to the power supply unit 18, so that The microwave signal transmitter 131 at the transmitting end is in the state of prohibiting transmission, and at the same time cut off the power supply of the USB3.0 microwave receiving end to reduce power consumption; when the data cable connected to the host computer is reconnected, and the host computer is turned on, the power supply of the USB3.0 port is normal In this case, the MCU control unit 14 of the USB3.0 microwave transmitting end sends an instruction to the power supply unit 18 to restore the power supply of the USB3.0 microwave receiving end, and the microwave signal transmitter 232 of the USB3.0 microwave receiving end sends out a link initialization signal.
5. 如果USB3.0微波接收端的USB3.0终端设备工作不正常，计算机主机可以通过管理接口16向发送端的MCU控制单元14发出指令，发送端的MCU控制单元14通过侦测电路17的光耦电路将指令传递到接收端的MCU控制单元24的D_Com_RX输入引脚2422，进一步地，接收端的MCU控制单元24通过电源管理PM_OUT信号输出引脚2818向接收端的供电单元28发出端口电源状态检测指令，如果不存在电流过载情况，则发出端口电源重启指令，从而使USB3.0终端设备进行冷启动。5. If the USB3.0 terminal device at the USB3.0 microwave receiving end does not work normally, the host computer can issue instructions to the MCU control unit 14 at the sending end through the management interface 16, and the MCU control unit 14 at the sending end passes through the optocoupler circuit of the detection circuit 17 The instruction is delivered to the D_Com_RX input pin 2422 of the MCU control unit 24 of the receiving end. Further, the MCU control unit 24 of the receiving end sends a port power state detection instruction to the power supply unit 28 of the receiving end through the power management PM_OUT signal output pin 2818. If not If there is a current overload situation, a port power restart command is issued, so that the USB3.0 terminal device performs a cold start.
6. 在微波发射芯片在输入信号检测超时和微波接收芯片在输入微波信号检测超时这两种情况下，芯片都会进入待机状态，如果微波发射芯片输入信号重新被检测到，则会立即退出待机进入激活状态；如果微波接收芯片输入微波信号重新被检测到，则会立即退出待机进入激活状态。6. In the two cases of the microwave transmitting chip’s input signal detection timeout and the microwave receiving chip’s input microwave signal detection timeout, the chip will enter the standby state. If the input signal of the microwave transmitting chip is detected again, it will immediately exit the standby mode and enter Active state; if the input microwave signal of the microwave receiving chip is detected again, it will immediately exit the standby state and enter the active state.
