具体实施方式Detailed ways
下面结合附图，对本发明的具体实施方式进行详细描述，但应当理解本发明的保护范围并不受具体实施方式的限制。The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
除非另有其它明确表示，否则在整个说明书和权利要求书中，术语“包括”或其变换如“包含”或“包括有”等等将被理解为包括所陈述的元件或组成部分，而并未排除其它元件或其它组成部分。Unless expressly stated otherwise, throughout the specification and claims, the term "comprises" or its variations such as "comprises" or "comprising" will be understood to include the stated elements or components, and to Other elements or other components are not excluded.
图1是根据本发明的一个实施方式的会场布置示意图。如图1所示，在典型的大型会场环境中，会场可以被分为多个区域。在图1所示的示例中，会场被分为4个区域，其中该4个区域的物理中心位置分别为中心位置A-D(在图中中心位置由圆圈表示，本领域技术人员应该理解，图中以圆圈示出中心位置是为了示意清楚，以便本领域技术人员能够理解本发明，实际中，中心位置可以由一组坐标表示)，根据会场的布置规划，每个区域中具有零个、一个或者多个语音播放终端(在图中以三角形表示)，在本发明中，虽然被命名为“语音播放终端”，但是该语音播放终端也可以具有接收话音的功能。同时，由于语音播放终端可以是一套随身携带设备，所以参会者可能会不定时的移动位置，如图所示，语音播放终端有可能从区域C移动到区域A(在图中由三角和箭头的组合表示)。为了顺利实现将话音从一个终端传输到另一个终端以实现一对一通话，可以设置一中央控制器(图中中央控制器以方框示出是为了本领域技术人员能够清楚识别中央控制器的示意性位置，本领域技术人员应该能够理解，实际中中央控制器不会占用如此大的面积)。例如如果区域A的语音播放终端希望将话音传输给区域C的语音播放终端，那么区域A的语音播放终端可以先将话音信息发送给中央控制器，然后中央控制器再将话音信息发送给区域C的语音播放终端。这样可以解决距离较远的终端之间话音传输的问题。例如会场要播放提前录播的重要讲话，或者需要实况转播重要讲话，那么以预先将讲话录音加载到中央控制器中，或者将外界信号接入中央控制器，然后再由中央控制器将相关话音传输到语音播放终端，由此实现将话音从一个终端发送到多个终端以实现听讲功能。Figure 1 is a schematic diagram of the venue layout according to an embodiment of the present invention. As shown in Figure 1, in a typical large-scale venue environment, the venue can be divided into multiple areas. In the example shown in Figure 1, the venue is divided into four areas, where the physical center positions of the four areas are center positions A-D respectively (the center position is represented by a circle in the figure. Those skilled in the art should understand that in the figure The central position is shown in a circle for clarity, so that those skilled in the art can understand the present invention. In practice, the central position can be represented by a set of coordinates). According to the layout plan of the venue, each area has zero, one or Multiple voice playback terminals (represented by triangles in the figure) are named "voice playback terminals" in the present invention, but the voice playback terminals may also have the function of receiving speech. At the same time, since the voice playback terminal can be a portable device, participants may move from time to time. As shown in the figure, the voice playback terminal may move from area C to area A (in the figure represented by triangles and combination of arrows). In order to smoothly transmit voice from one terminal to another terminal to achieve one-to-one communication, a central controller can be provided (the central controller is shown as a block in the figure so that those skilled in the art can clearly identify the central controller. (Those skilled in the art should be able to understand that the central controller will not occupy such a large area in practice). For example, if the voice playback terminal in area A wants to transmit voice to the voice playback terminal in area C, the voice playback terminal in area A can first send the voice information to the central controller, and then the central controller sends the voice information to area C. voice playback terminal. This can solve the problem of voice transmission between terminals that are far away. For example, if the venue wants to play an important speech that has been recorded in advance, or needs to broadcast an important speech live, the speech recording can be loaded into the central controller in advance, or external signals can be connected to the central controller, and then the central controller can transmit the relevant speech. Transmitted to the voice playback terminal, thereby enabling the voice to be sent from one terminal to multiple terminals to achieve the listening function.
图2是根据本发明的一个实施方式的会场布置示意图。图2所示的会场布置与图1所示的会场布置类似，区别在于图2中区域A-D为不规则划分，具体而言，区域A面积最大，区域B和D中等面积且面积相等，区域C面积最小，如此进行划分的主要原因是区域A和C之间存在一信号屏蔽，信号屏蔽的具体原因可以有多种，例如该处存在遮挡信号的物理实体，或者例如该处存在较多信号干扰等等，在区域A和C之间存在信号屏蔽的条件下，需要中央控制器，以便区域A的语音播放终端能够将话音传输给区域C的语音播放终端。本领域技术人员应该理解，区域的划分应该是灵活自由的，甚至中央控制器不必设置在会场正中心，例如可以划分多于4个的区域，例如可以每个区域的边界形状为五边形、六边形或者多边形等等，优选将会场划分为多个正方形、等边五边形、等边六边形、圆形的区域。Figure 2 is a schematic diagram of the venue layout according to an embodiment of the present invention. The venue layout shown in Figure 2 is similar to the venue layout shown in Figure 1. The difference is that areas A-D in Figure 2 are irregularly divided. Specifically, area A has the largest area, areas B and D are medium and equal in area, and area C The area is the smallest. The main reason for such division is that there is a signal shielding between areas A and C. The specific reasons for signal shielding can be many, such as there is a physical entity blocking the signal there, or there is a lot of signal interference there. Etc., under the condition that there is signal shielding between areas A and C, a central controller is needed so that the voice playback terminal in area A can transmit voice to the voice playback terminal in area C. Those skilled in the art should understand that the division of areas should be flexible and free, and the central controller does not even need to be set in the center of the venue. For example, more than four areas can be divided. For example, the boundary shape of each area can be a pentagon, Hexagons or polygons, etc., preferably divide the venue into multiple square, equilateral pentagon, equilateral hexagon, or circular areas.
图3是根据本发明的一个实施方式的会场布置示意图。在图3的示例中，其基本布置与图1和2中的示例类似，但是图3的示例中，由于会场的某些特殊要求，会场中布置有一些禁止区域，在禁止区域中，不允许布置语音播放终端。在实现该套系统的过程中，需要考虑几个问题，首先是如何较为简便和低开销的实现信号的传输；其次由于语音播放终端可能在会议过程中移动位置，因此在语音播放终端移动位置时，如何更新其所在区域；此外是如何合理分配资源以保证传输速度。Figure 3 is a schematic diagram of the venue layout according to an embodiment of the present invention. In the example of Figure 3, the basic layout is similar to the examples in Figures 1 and 2. However, in the example of Figure 3, due to some special requirements of the venue, there are some prohibited areas arranged in the venue. In the prohibited areas, no Arrange voice playback terminals. In the process of implementing this system, several issues need to be considered.

图3是根据本发明的一个实施方式的方法流程图。如图所示，本发明的语音设备的操作方法包括如下步骤：Figure 3 is a method flow chart according to an embodiment of the present invention. As shown in the figure, the operating method of the voice device of the present invention includes the following steps:
步骤1：在设备初始配置阶段，语音播放终端A向中央控制器发送注册信息A，其中，注册信息A中包括语音播放终端A的个体标识符A以及语音播放终端A的位置信息A，其中，语音播放终端A与中心位置A之间的距离小于距离门限值A；在一个示例中，设备初始配置阶段是指语音播放终端与中央控制器均上电开始调试，但是会议尚未开始的阶段；一般而言在该阶段，用户首先需要将语音播放终端与中央控制器建立基本的通信连接，并进行必要的语音清晰度的调试，在该阶段没有会议信息的传输，每个区域内的语音播放终端均会向中央控制器发送注册信息；在一个示例中，语音播放终端A的个体标识符A可以是设备初始化配置的一个标识符，例如某会议组织者购买了一套一台中央控制器和1000台语音播放终端的语音设备，则在初始化配置设备时，语音播放终端A可以被分配有0-999中的任一一个自然数的个体标识符A；在一个示例中，初始化配置需要管理员权限，例如如果该会议组织者随后又更新了设备，加构了1000台语音播放终端，那么该会议组织者可以要求硬件提供商派工程师帮助更新和重新配置系统，该工程师可以被赋予管理员权限；在一个示例中，语音播放终端A的位置信息A可以指语音播放终端A的坐标信息，在一个示例中，语音播放终端A与中心位置A之间的距离可以通过简单的三角函数方法求得；在一个示例中，作为一个原则，距离门限值主要由区域的几何形状决定，由于会场具体布置不明确，本发明无法给出一个具体数值或者一种具体算法，但是本领域技术人员一旦明确会场具体布置情况，能够通过本发明的公开内容结合基本的数学计算得到距离门限值；Step 1: In the initial configuration stage of the device, the voice playback terminal A sends registration information A to the central controller, where the registration information A includes the individual identifier A of the voice playback terminal A and the location information A of the voice playback terminal A, where, The distance between the voice playback terminal A and the central location A is less than the distance threshold value A; in one example, the initial configuration stage of the equipment refers to the stage where both the voice playback terminal and the central controller are powered on and start debugging, but the conference has not yet started; Generally speaking, at this stage, the user first needs to establish a basic communication connection between the voice playback terminal and the central controller, and perform necessary voice clarity debugging. There is no transmission of conference information at this stage, and the voice playback in each area All terminals will send registration information to the central controller; in one example, the individual identifier A of the voice playback terminal A can be an identifier of the initial configuration of the device. For example, a conference organizer purchased a set of a central controller and For a voice device with 1,000 voice playback terminals, when initializing the configuration of the device, the voice playback terminal A can be assigned an individual identifier A of any natural number from 0 to 999; in one example, the initial configuration requires an administrator Permissions. For example, if the conference organizer subsequently updates the device and adds 1,000 voice playback terminals, the conference organizer can ask the hardware provider to send an engineer to help update and reconfigure the system, and the engineer can be given administrator rights. ; In one example, the location information A of the voice playback terminal A may refer to the coordinate information of the voice playback terminal A. In one example, the distance between the voice playback terminal A and the center position A can be obtained by a simple trigonometric function method. ; In one example, as a principle, the distance threshold value is mainly determined by the geometric shape of the area. Since the specific layout of the venue is unclear, the present invention cannot give a specific value or a specific algorithm, but once it is clear to those skilled in the art For the specific layout of the venue, the distance threshold can be obtained through the disclosure of the present invention combined with basic mathematical calculations;
步骤2：在接收到注册信息A之后，中央控制器确定语音播放终端A与中心位置A之间的距离小于距离门限值A；Step 2: After receiving the registration information A, the central controller determines that the distance between the voice playback terminal A and the central location A is less than the distance threshold A;
步骤3：在确定语音播放终端A与中心位置A之间的距离小于距离门限值A之后(在图1-3的示例中，可以认为语音播放终端A位于区域A)，中央控制器向语音播放终端A发送传输资源配置信息A，其中，传输资源配置信息A包括对于传输资源的指示A、语音播放终端A的个体标识符A以及群组标志A，其中，对于传输资源的指示A指示的资源A具有第一大小，其中，第一大小是由中央控制器基于在设备初始配置阶段接收到的第一类注册信息的数量来确定的，其中，发送第一类注册信息的语音播放终端与中心位置A之间的距离均小于距离门限值。在一个示例中，传输资源配置信息A中包括的语音播放终端A的个体标识符A是为了使得语音播放终端A能够明确该信息传输资源配置信息A是发送给自己的信息；在一个示例中，群组标志A是为了接下来的组播或者广播传输配置的标识符；在一个示例中，设备初始配置阶段可以被配置为10分钟，在该段时间之内，中央控制器监听会场内所有语音播放终端发送的注册信息，并基于语音播放终端的位置来将语音播放终端分组并统计某类注册信息的数量；在一个最简单的算法示例中，在一个传输周期内，假定中央控制器总共可以分配10000时频资源单位的资源，假定在设备初始配置阶段，中央控制器接收到区域A中300个设备的注册信息，中央控制器接收到区域B中400个设备的注册信息，中央控制器接收到区域C中300个设备的注册信息，那么中央控制器给区域A中的语音播放终端分配3000时频资源单位的资源；在更复杂的算法中，分配资源的数量除了考虑注册信息数量之外，还可以考虑各个语音播放终端的优先级，例如在区域A中就坐的可能都是需要发言的参会者，所以可以给该区域的语音播放终端设置更高优先级，高优先级的区域可以具有较大的权重数值，例如在一个示例中，如前面简单算法所示，最终计算给区域A中的语音播放终端分配3000时频资源单位(如果使用OFDM传输模式，则时频资源单位可以具有若干子载波以及若干OFDM符号)的资源，但是区域A可能具有高优先级，权重系数是1.2，那么根据较为复杂的算法，应该给区域A中的语音播放终端分配3600(3000*1.2)时频资源单位的资源；在一个示例中，传输资源配置信息A可以携带区域A内所有终端的个体标识符，从而使得区域A之内的语音播放终端可以了解区域A内的所有语音播放终端；Step 3: After determining that the distance between the voice playback terminal A and the central location A is less than the distance threshold value A (in the example of Figure 1-3, the voice playback terminal A can be considered to be located in area A), the central controller Playback terminal A sends transmission resource configuration information A, where transmission resource configuration information A includes an indication A for transmission resources, an individual identifier A and a group identifier A for voice playback terminal A, where the indication A for transmission resources indicates Resource A has a first size, where the first size is determined by the central controller based on the number of first-type registration information received during the initial configuration phase of the device, where the voice playback terminal sending the first-type registration information is The distances between center positions A are all less than the distance threshold. In one example, the individual identifier A of the voice playback terminal A included in the transmission resource configuration information A is to enable the voice playback terminal A to make it clear that the information transmission resource configuration information A is information sent to itself; in one example, Group flag A is an identifier configured for subsequent multicast or broadcast transmission; in one example, the initial configuration phase of the device can be configured for 10 minutes. During this period, the central controller monitors all voices in the venue. Play the registration information sent by the terminal, and group the voice playing terminals based on the location of the voice playing terminal and count the number of certain types of registration information; in the simplest algorithm example, within a transmission cycle, it is assumed that the central controller can Allocate 10,000 time-frequency resource units. Assume that during the initial configuration phase of the device, the central controller receives the registration information of 300 devices in area A, the central controller receives the registration information of 400 devices in area B, and the central controller receives to the registration information of 300 devices in area C, then the central controller allocates 3000 time-frequency resource units to the voice playback terminals in area A; in a more complex algorithm, the number of allocated resources not only takes into account the number of registration information , you can also consider the priority of each voice playback terminal. For example, those sitting in area A may be participants who need to speak, so you can set a higher priority for the voice playback terminals in this area. High-priority areas can has a larger weight value. For example, in one example, as shown in the previous simple algorithm, the final calculation is to allocate 3000 time-frequency resource units to the voice playback terminal in area A (if the OFDM transmission mode is used, the time-frequency resource unit can have resources of several subcarriers and several OFDM symbols), but area A may have high priority and the weight coefficient is 1.2. Then according to a more complex algorithm, the voice playback terminal in area A should be allocated 3600 (3000*1.2) time frequency Resources of resource units; in one example, transmission resource configuration information A can carry individual identifiers of all terminals in area A, so that voice playback terminals in area A can learn about all voice playback terminals in area A;
