Description

多协议互操作的通信设备及通信方法Multi-protocol interoperable communication device and communication method 技术领域Technical field
本发明涉及信息通信技术领域,尤其涉及一种多协议互操作的通信设备及通信方法。The present invention relates to the field of information communication technologies, and in particular, to a multi-protocol interworking communication device and a communication method.
背景技术Background technique
随着通信技术的迅速发展,出现了多种不同的通信协议,以满足不同的需求。例如,WiFi通信协议、蓝牙(Bluetooth)通信协议、ZigBee通信协议、第三/四代(3G/4G)通信协议和卫星通信协议等。上述协议的发展,虽然满足了人类多种需求,但是由于协议的多样化,一种通信协议的用户不能和另外一种通信协议的用户相互通信,也就是协议之间不具备互操作性。采用不同协议的各种设备之间不具备互操作性给人们的生活带来很多的困扰。例如:在应急救灾的过程当中,多个部门(包括医疗、警察、消防急救、部队、各个国家内部的慈善救援机构、国际救援和慈善机构等)由于不能相互通信,导致了各方不能协调一致地工作,降低了救援效率。With the rapid development of communication technology, a variety of different communication protocols have emerged to meet different needs. For example, a WiFi communication protocol, a Bluetooth communication protocol, a ZigBee communication protocol, a third/fourth generation (3G/4G) communication protocol, a satellite communication protocol, and the like. Although the development of the above-mentioned protocols satisfies the various needs of human beings, due to the diversification of protocols, users of one communication protocol cannot communicate with users of another communication protocol, that is, there is no interoperability between protocols. The lack of interoperability between devices using different protocols has caused many problems for people's lives. For example, in the process of emergency response, multiple departments (including medical, police, fire emergency, troops, charitable relief agencies within various countries, international relief and charities, etc.) cannot communicate with each other, resulting in inconsistencies Working in the ground reduces the efficiency of rescue.
为了解决通信系统之间不具有互操作性的问题,除了政府间加强协作,协调各国间的通信协议以外,人们采取各种技术手段,以尝试从根本上解决这个问题。从已公开的专利来看,所采取的技术手段主要有两类:In order to solve the problem of non-interoperability between communication systems, in addition to strengthening cooperation between governments and coordinating communication protocols between countries, people adopt various technical means to try to solve this problem fundamentally. From the perspective of published patents, there are two main technical means adopted:
第一类技术手段:The first type of technical means:
预先分配资源,采用不同协议的设备按照分配的资源,调节通信模式,达到具备互操作性的目的。此发明方法的专利代表例如为美国专利(专利号为US 8280364 B1),其全文引入本文作为参考。与该类方法相似的美国专利文献(标题为:Communication Assets Survey and Mapping Tool(通信资源监测和映射工具)公开号为US 20140310400 A1),其全文引入本文作为参考。然而,该类方案存在如下缺点:一方面,设备必须预留预先协调好的资源来与中心控制器通信。这对于新的设备来说,如果没有预留的资源,就无法加入到系统中。另一方面,所有的通信设备只是归类,同一类的设备可以相互通信,但是不同类的通信设备仍然无法通信,这不能从根本上解决互操作性的问题。 Pre-allocating resources, devices using different protocols adjust the communication mode according to the allocated resources, and achieve the purpose of interoperability. A patented representative of this method of the invention is, for example, U.S. Patent No. U.S. Patent No. 8,280,364, the entire disclosure of which is incorporated herein by reference. A U.S. patent document similar to this type of method (title: Communication Assets Survey and Mapping Tool) is disclosed in US Patent Application Publication No. US 20140310400 A1, which is incorporated herein in its entirety by reference. However, this type of solution has the following disadvantages: On the one hand, the device must reserve pre-harmonized resources to communicate with the central controller. For new devices, if there are no reserved resources, they cannot be added to the system. On the other hand, all communication devices are only classified, and devices of the same class can communicate with each other, but communication devices of different types are still unable to communicate, which cannot fundamentally solve the problem of interoperability.
第二类技术手段:The second type of technical means:
第二类技术手段比第一类技术手段更进一步。第二类技术手段不对现有的通信设备做任何要求。它是通过一个第三类设备和自己对应的接口模块相互通信。第三类设备之间形成一个新网络,数据通过这个新的网络交互,间接地满足互操作性的问题。其中,第三类设备网络的实现有两种方法。第一种方法是通过另外一个共有频段形成一个新的网络。例如:美国专利(专利号为:US7508840 B2),其全文引入本文作为参考。第二种方法例如:美国专利(专利号为:US6185205 B1),其全文引入本文作为参考。第二种方法主要是改变数据的格式,将从不同协议中采集的数据按照另外新的协议重新格式化,以满足数据之间的兼容性。然而,上述第二种方法虽然通过统一数据格式的方式满足了不同协议之间的互操作性,但是系统比较复杂,需要一个第三类的协议来间接满足互操作性,而且所采用设备的体积庞大,耗电多,不便于携带,适用性差,无法满足应急救援等场合的应用。The second type of technical means goes further than the first type of technical means. The second type of technical means does not impose any requirements on existing communication equipment. It communicates with each other through a third type of device and its own corresponding interface module. A new network is formed between the third type of devices, and data interacts indirectly through this new network to meet interoperability problems. Among them, there are two methods for implementing the third type of device network. The first method is to form a new network through another common frequency band. For example: U.S. Patent (Patent No.: U.S. Patent No. 7,508, 840 B2), which is incorporated herein by reference in its entirety. A second method is described, for example, in U.S. Patent No. US Pat. No. 6,158,205, the entire disclosure of which is incorporated herein by reference. The second method is mainly to change the format of the data, and the data collected from different protocols is reformatted according to another new protocol to meet the compatibility between the data. However, although the above second method satisfies the interoperability between different protocols by means of a unified data format, the system is relatively complicated, and a third type of protocol is needed to indirectly satisfy the interoperability, and the volume of the device used. It is huge, consumes a lot of electricity, is not easy to carry, has poor applicability, and cannot meet the application of emergency rescue and other occasions.

为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。此外,在本文中,对一些常规的公知结构或实现细节不再详细描述,以避免使本发明技术方案的实质模糊不清。The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. In addition, some conventional well-known structures or implementation details are not described in detail herein to avoid obscuring the nature of the invention.
图1为本发明一种实施方式的多协议互操作的通信设备功能模块结构示意图。FIG. 1 is a schematic structural diagram of a function module of a multi-protocol interoperation communication device according to an embodiment of the present invention.
如图1所示:多协议互操作的通信设备可以包括:第一接口组件100、第二接口组件200和微控制器300。其中:As shown in FIG. 1, the multi-protocol interoperable communication device may include: a first interface component 100, a second interface component 200, and a microcontroller 300. among them:
第一接口组件100可以为采用标准通信协议的信息提供信息传输的接 口。The first interface component 100 can provide information transmission for information using standard communication protocols. mouth.
在本实施方式中,第一接口组件100支持现有的标准通信协议。现有的标准通信协议例如可以是WiFi通信协议、3G通信协议、4G通信协议、ZigBee通信协议、LAN通信协议、蓝牙通信协议、固定电话通信协议和卫星通信协议等。在实际应用中,特别是应急救援的过程中,本实施方式可以为多个国家的多个部门提供方便。参与救援的这些部门可以采用各自的标准通信协议。对应用于不同的标准通信协议,第一接口组件100可以包括一个或者多个以下接口:WiFi接口、3G接口、4G接口(也可以是以后开发出的5G接口)、ZigBee接口、LAN接口(图中未标注)、蓝牙接口、固定电话接口(图中未标注)和卫星通信接口(图中未标注)等。需要说明的是,图中并未列出所有的接口,本领域的技术人员可以理解,第一接口组件100中还可以拓展出更多接口,本申请对拓展的接口的数量不作限制;并且,拓展出的接口还可以包括上文中未提及的以及未来开发的其他类别的接口,本申请在此方面没有限制。上述接口均可以采用现有的国际标准用于支持对应的协议的通信。这些接口模块相互独立,在采用相应的协议通信时,互相不干扰。基于特定协议的信息传输通道的配置方法为现有技术,在此不再赘述。由此,本实施方式通过设置多个与不同标准协议相匹配的接口,使得该设备与其它通信设备能够自由通信,增强了产品的实用性。In the present embodiment, the first interface component 100 supports existing standard communication protocols. The existing standard communication protocols may be, for example, a WiFi communication protocol, a 3G communication protocol, a 4G communication protocol, a ZigBee communication protocol, a LAN communication protocol, a Bluetooth communication protocol, a fixed telephone communication protocol, and a satellite communication protocol. In practical applications, especially in the process of emergency rescue, the present embodiment can provide convenience for multiple departments in multiple countries. These departments involved in the rescue can use their own standard communication protocols. For application to different standard communication protocols, the first interface component 100 may include one or more of the following interfaces: a WiFi interface, a 3G interface, a 4G interface (which may also be a 5G interface developed in the future), a ZigBee interface, and a LAN interface (Figure Not marked in the), Bluetooth interface, fixed telephone interface (not shown) and satellite communication interface (not shown). It should be noted that all the interfaces are not listed in the figure. It can be understood by those skilled in the art that more interfaces can be extended in the first interface component 100, and the number of extended interfaces is not limited in this application; The expanded interface may also include other types of interfaces not mentioned above and developed in the future, and the application is not limited in this respect. All of the above interfaces can use existing international standards to support communication of the corresponding protocol. These interface modules are independent of each other and do not interfere with each other when communicating using the corresponding protocol. The configuration method of the information transmission channel based on the specific protocol is the prior art, and details are not described herein again. Thus, the present embodiment enhances the practicability of the product by providing a plurality of interfaces that match different standard protocols, so that the device can communicate freely with other communication devices.
第二接口组件200可以为采用自定义的非标准化通信协议的信息提供信息传输的接口。The second interface component 200 can provide an interface for information transfer using information of a custom, non-standardized communication protocol.
为了将一些非标准化的协议纳入通信系统之中,或者为了满足未来新的通信协议的需求,本实施方式还设置了基于软件无线电(Software Defined Radio:SDR)技术的第二接口组件200。第二接口组件200可以包括一个或者多个无线电接口(SDR接口,例如:SDR-1接口和SDR-N接口等,其中,N为自然数)。这些SDR接口可以是基于不同的无线电波段(例如中、低频率波段)进行自定义通信协议的无线电接口。由此,本实施方式根据不同的无线电波段自定义通信协议,使得协议程序简单、规范、方便扩展、可靠性强。In order to incorporate some non-standardized protocols into the communication system, or to meet the requirements of future new communication protocols, the present embodiment also provides a second interface component 200 based on Software Defined Radio (SDR) technology. The second interface component 200 can include one or more radio interfaces (SDR interfaces, such as SDR-1 interfaces and SDR-N interfaces, etc., where N is a natural number). These SDR interfaces may be radio interfaces that make custom communication protocols based on different radio bands (eg, medium and low frequency bands). Therefore, the present embodiment customizes the communication protocol according to different radio bands, so that the protocol program is simple, standardized, convenient to expand, and highly reliable.
微控制器300包括虚拟交换模块,为采用不同通信协议的信息提供交互。其中,微控制器300是必须具备可虚拟化技术的控制器。微控制器可以基于 虚拟化技术虚拟化出虚拟系统中的各个功能组件。Microcontroller 300 includes a virtual switching module that provides interaction for information that employs different communication protocols. Among them, the microcontroller 300 is a controller that must have a virtualization technology. The microcontroller can be based on Virtualization technology virtualizes the various functional components in a virtual system.
图2为图1中的微控制器构建多个虚拟器组成的虚拟系统的框架示意图。如图2所示,该虚拟系统包括服务应用层、操作系统层、管理层和硬件层。其中:服务应用层包括7个服务应用(APP)(服务应用1-服务应用7)。操作系统层包括对应于各个服务应用的7个操作系统(OS)(操作系统1-操作系统7)。需要说明的是,上述操作系统可以是同一种类型的操作系统,也可以是不同类型的,或者是其中有部分操作系统是相同类型的,本申请在此方面没有限制。管理层包括管理程序(secure hypervisor)。硬件层包括中央处理器(例如MIPS M-class CPU)。上述各层的实现是基于微控制器300。2 is a schematic diagram of a framework of a virtual system composed of a plurality of virtual devices in the microcontroller of FIG. 1. As shown in FIG. 2, the virtual system includes a service application layer, an operating system layer, a management layer, and a hardware layer. The service application layer includes seven service applications (APPs) (service applications 1 - service applications 7). The operating system layer includes seven operating systems (OS) (Operating System 1 - Operating System 7) corresponding to respective service applications. It should be noted that the foregoing operating systems may be the same type of operating system, different types, or some of the operating systems are of the same type, and the application is not limited in this respect. The management includes a secure hypervisor. The hardware layer includes a central processing unit (such as a MIPS M-class CPU). The implementation of each of the above layers is based on the microcontroller 300.
在本实施方式中,微控制器300可以采用Imagination Technologies公司的型号为MIPS M5150的微控制器。该公司的MIPS M系列微控制器是世界上最早实现虚拟技术的。M系列支持Hardware Virtualization,目前为止可以支持多个(例如7个)虚拟操作系统。In the present embodiment, the microcontroller 300 can be a microcontroller of the MIPS M5150 model from Imagination Technologies. The company's MIPS M-series microcontrollers are the world's first to implement virtual technology. The M Series supports Hardware Virtualization and has so far supported multiple (for example, seven) virtual operating systems.
继续参考图1和图2,在本实施方式中,上述虚拟交换模块可以包括多个对应于不同协议的虚拟器(例如可以是WiFi虚拟器、3G/4G虚拟器、以后开发出的5G虚拟器、ZigBee虚拟器、LAN虚拟器、蓝牙虚拟器、固定电话虚拟器和卫星通信虚拟器等)。每个虚拟器具有特定的ID(这些虚拟器的ID号用于标识虚拟器,每个ID号不相同)。在具体通信连接时,各个接口与其适配的虚拟器相连接。例如:WiFi接口与WiFi虚拟器连接,3G/4G接口与3G/4G虚拟器相连接,ZigBee接口与ZigBee虚拟器相连接,LAN接口与LAN虚拟器相连接,蓝牙接口与蓝牙虚拟器相连接,固定电话接口(图中未标注)与固定电话虚拟器(图中未标注)相连接,卫星通信接口(图中未标注)与卫星通信虚拟器(图中未标注)相连接。With reference to FIG. 1 and FIG. 2, in the embodiment, the virtual switching module may include multiple virtual devices corresponding to different protocols (for example, may be a WiFi virtual machine, a 3G/4G virtual device, or a 5G virtual device developed later). , ZigBee virtual machine, LAN virtual machine, Bluetooth virtual machine, fixed telephone virtual machine and satellite communication virtual machine, etc.). Each virtual machine has a specific ID (the ID numbers of these virtual machines are used to identify the virtual machines, and each ID number is not the same). When a specific communication connection is made, each interface is connected to its adapted virtual machine. For example, the WiFi interface is connected to the WiFi virtual device, the 3G/4G interface is connected to the 3G/4G virtual device, the ZigBee interface is connected to the ZigBee virtual device, the LAN interface is connected to the LAN virtual device, and the Bluetooth interface is connected to the Bluetooth virtual device. The fixed telephone interface (not shown) is connected to the fixed telephone virtual machine (not shown), and the satellite communication interface (not shown) is connected to the satellite communication virtual unit (not shown).
在本实施方式中,通信设备还包括虚拟路由器。虚拟路由器用于提供虚拟器之间进行信息交互的传输路径,使得与具有不同ID的虚拟器分别对应的采用不同通信协议的信息根据虚拟路由器确定的传输路径进行交互。In this embodiment, the communication device further includes a virtual router. The virtual router is configured to provide a transmission path for information interaction between the virtual devices, so that information corresponding to the different communication protocols corresponding to the virtual devices having different IDs is exchanged according to the transmission path determined by the virtual router.
在本实施方式的微控制器支持的虚拟系统中,每一个虚拟系统和一种接口通信协议相连接,完成一个系统支持多种通信协议的目的。各个虚拟器内部的信息交换可以通过成熟的虚拟交换(Virtual Switch)技术来实现。例如开源软件Open vSwitch即可实现数据交换的目的。数据的交换也可以通过开 发新的路由协议来实现。In the virtual system supported by the microcontroller of the present embodiment, each virtual system is connected with an interface communication protocol to complete the purpose of supporting multiple communication protocols in one system. The information exchange inside each virtual machine can be realized by the mature Virtual Switch technology. For example, the open source software Open vSwitch can achieve the purpose of data exchange. Data exchange can also be opened A new routing protocol is implemented.
在本实施方式中,虚拟层路由器可以采用管理程序(Secure Hypervisor)中数据交换技术实现。Hypervisor可以协调硬件资源(例如微控制器)对虚拟器的访问,以及各个虚拟机之间的防护。在硬件资源启动时,它会加载所有虚拟机客户端的操作系统,同时为虚拟机分配内存、磁盘和网络等。In this embodiment, the virtual layer router can be implemented by using a data exchange technology in a hypervisor (Secure Hypervisor). The Hypervisor coordinates the access of virtual resources (such as microcontrollers) to virtual machines and the protection between individual virtual machines. When the hardware resource starts, it loads the operating system of all virtual machine clients, while allocating memory, disk, network, etc. to the virtual machine.
此外,虚拟技术是一个常规的技术。虚拟技术主要用于实现一个硬件平台下多个系统的运行。该技术主要在常规的计算机上实现。例如采用Windows系统的计算机中实现的Linux模拟环境就是一种虚拟技术。再例如云计算也大量采用虚拟技术。通常计算机可以实现很强的计算的功能,但不具有很强的通信能力。另外,计算机体积太大,不方便用于接通电话等需要小巧、灵活的通信设备(例如智能手机)的需求。因此,目前人们还没有在常规的计算机中利用虚拟技术解决通信的技术方案。本实施方式通过使用虚拟技术实现微处理器300代替庞大的服务器,不仅满足不同协议之间的互操作性,而且可以设计成体积小、硬件结构简单、重量轻、耗电少、可以仅仅靠普通的电池支持其供电的设备(例如智能手机),便于个人携带,特别适合应急、救援等场合应用。In addition, virtual technology is a conventional technology. Virtual technology is mainly used to implement the operation of multiple systems under one hardware platform. This technology is mainly implemented on a conventional computer. For example, the Linux simulation environment implemented in a computer using a Windows system is a virtual technology. For example, cloud computing also uses a large number of virtual technologies. Usually computers can achieve very powerful computing functions, but they do not have strong communication capabilities. In addition, the computer is too large to be used for the need to connect a telephone, such as a small, flexible communication device (such as a smart phone). Therefore, at present, there is no technical solution for utilizing virtual technology to solve communication in a conventional computer. By using the virtual technology to implement the microprocessor 300 instead of the huge server, the embodiment not only satisfies the interoperability between different protocols, but also can be designed to be small in size, simple in hardware structure, light in weight, low in power consumption, and can be used only by ordinary The battery supports the device that it supplies (such as a smart phone), which is convenient for individuals to carry, and is especially suitable for emergency, rescue and other occasions.
图3为本发明另一种实施方式的针对多协议的通信设备功能模块结构示意图。如图3所示,本实施方式在图1实施方式的基础上增加了多波段天线400、无线电收发机500和FPGA(现场可编程门阵列:Field Programmable Gate Array)600。其中,多波段天线400可以与无线电收发机500连接,FPGA 600可以分别与无线电收发机500和第二接口组件200连接。FIG. 3 is a schematic structural diagram of a function module of a communication device for multiple protocols according to another embodiment of the present invention. As shown in FIG. 3, in the present embodiment, a multi-band antenna 400, a radio transceiver 500, and an FPGA (Field Programmable Gate Array) 600 are added to the embodiment of FIG. Wherein, the multi-band antenna 400 can be connected to the transceiver 500, and the FPGA 600 can be connected to the transceiver 500 and the second interface component 200, respectively.
在本实施方式中,通过FPGA 600可以对自定义通信协议进行软件更新。无线电收发机500可以接收或者发射多个波段的无线电的信号。In the present embodiment, the software communication can be performed by the FPGA 600 on the custom communication protocol. The transceiver 500 can receive or transmit signals of radios of multiple bands.
在本实施方式中,软件无线技术可以采用成熟的技术来实现。其中一个常用的技术是FPGA。FPGA可以让开发者快速的进行功能设计、编制软件以及下载软件到FPGA中运行,并可实现反复修改和下载。以Xilinx FPGA模块为例,通过CPLD(Complex Programmable Logic Device:复杂可编程逻辑器件)XC95288X可实现软件的远程或者本地更新。以FPGA实现SDR的技术也很成熟,例如美国专利申请(Software Defined Radio(软件无线电),公开号:US20040242261A1)公开了通过FPGA实现SDR的示例,其全文引 入本文作为参考。具体客户端可以将一些常用软件模块保存在数据库中(可以是云服务器内)。在应用时,在数据库中下载更新。该部分内容可以参考例如中国专利申请号201310452351.1的专利文献公开的内容,其全文引入本文作为参考。由此,本实施方式通过FPGA对自定义的通信协议进行软件更新,便于设计成功能强大、耗电少、操作简单、体积小的通信产品。In this embodiment, the software wireless technology can be implemented using mature technology. One common technique is FPGA. FPGAs allow developers to quickly design functions, program software, and download software to run in FPGAs, with repeated modifications and downloads. Taking the Xilinx FPGA module as an example, remote or local update of software can be realized by CPLD (Complex Programmable Logic Device) XC95288X. The technology for implementing SDR in an FPGA is also very mature. For example, the US Patent Application (Software Defined Radio, Publication No. US20040242261A1) discloses an example of implementing SDR through an FPGA. This article is incorporated herein by reference. Specific clients can save some common software modules in the database (which can be in the cloud server). When applied, download updates in the database.

An example of ZigBee, Bluetooth, and WiFi exchanging data through a virtual machine's Shared File System Service is shown in this example.
首先,可以为采用标准通信协议的信息提供信息传输的接口。本实施方式中示出的是采用ZigBee、蓝牙、WiFi等标准通信协议的信息传输提供的ZigBee接口、蓝牙接口和WiFi接口。为了使本领域技术人员能够更好地理解本发明的实质,在本实施方式中并未示出与自定义协议相关的接口。 First, an interface for information transmission can be provided for information using standard communication protocols.
