背景技术Background technique
目前，大多数的测距方法是采用激光、电磁波(包括红外、蓝牙)和超声波进行测距，在测距方面，光波和电磁波在空气中传播的速度很快，接近30公里每秒，因此，很小的误差比如0.1秒的误差都将导致30000m的距离误差，不适合在中小距离范围内实现精确测距，另外，测距定位技术在多通道无线音响领域的应用，特别是在家庭影院中的应用更是寥寥无几，大多数无线音响都是按照厂家的出厂要求设置好的固定声道对应音响进行安装使用，这样往往致使音箱通道的匹配过于机械化，甚至不够合理。At present, most ranging methods use laser, electromagnetic waves (including infrared, bluetooth) and ultrasonic waves for ranging. In terms of ranging, light waves and electromagnetic waves travel very fast in the air, close to 30 kilometers per second. Therefore, A very small error such as an error of 0.1 second will lead to a distance error of 30000m, which is not suitable for accurate ranging in the small and medium distance range. In addition, the application of ranging positioning technology in the field of multi-channel wireless audio, especially in home theaters There are very few applications, and most wireless speakers are installed and used according to the manufacturer's factory requirements for fixed channel corresponding speakers, which often leads to too mechanized and even unreasonable matching of speaker channels.

本发明的多通道无线音响系统可以是5.1声道无线音响系统，也可以7.1声道无线音响系统或者其它多声道无线音响系统，下面本发明仅以7.1声道无线音响系统作为阐述的例子，7.1声道无线音响系统的音箱分布如图2所示，它包括一个中置主机音箱、两个前置分机音箱、两个中置分机音箱和两个后置分机音箱(环绕声音箱)，以及一个低音音箱(图中省略)。其中，所述的前、中、后置共6个分机音箱是无线的，中置主机音箱和低音音箱是有线的，中置主机音箱作为无线音响系统的发送端载体音箱，其它6个无线分机音箱是接收端载体音箱。The multi-channel wireless audio system of the present invention can be a 5.1-channel wireless audio system, or a 7.1-channel wireless audio system or other multi-channel wireless audio systems. The present invention only uses the 7.1-channel wireless audio system as an example for illustration below. The speaker distribution of the 7.1-channel wireless audio system is shown in Figure 2, which includes a central host speaker, two front extension speakers, two center extension speakers and two rear extension speakers (surround speakers), and A subwoofer (omitted in figure). Among them, the 6 extension speakers in the front, middle and rear are wireless, the central host speaker and subwoofer are wired, the central host speaker is used as the transmitting end carrier speaker of the wireless audio system, and the other 6 wireless extensions The speaker is the receiver carrier speaker.
如图1所示，本发明的多通道无线音响系统的音箱通道匹配方法包括：As shown in Figure 1, the speaker channel matching method of the multi-channel wireless audio system of the present invention comprises:
一、启动主机音箱，顺序接通每一个分机音箱，利用唯一的编码信息分别对每一个分机音箱与主机音箱之间进行配对，多通道无线音响系统中各音箱需要进行编码配对之后才能实现发送端和接收端之间一对一的工作。1. Start the host speaker, connect each extension speaker in sequence, and use the unique coding information to pair each extension speaker with the main speaker. In a multi-channel wireless audio system, each speaker needs to be coded and paired to realize the sending end. One-to-one work with the receiving end.
11)首先，定义多通道无线音响系统中实现主机音箱和各分机音箱之间进行通讯的唯一的机组码信息，以及为多通道无线音响系统中的各分机音箱分别定义唯一的机器码信息。其中，机组码信息是主机音箱出厂时由厂家设置好保存在MCU存储器中的系统配对码，它将用于多通道无线音响系统内的识别与配对，也即不同的多通道无线音响系统的机组码信息不一样，只有机组码信息相同的主机音箱与分机音箱之间才能进行通讯。机器码信息一般也是各分机音箱出厂时由厂家设置好保存在MCU存储器中的接收端认证码，它将用于发送端(主机音箱)对发送端(分机音箱)的身份识别(ID识别)和控制，也即当主机音箱的控制命令中附有机器码信息的分机音箱才会连通。11) First, define the unique unit code information for communication between the host speaker and each extension speaker in the multi-channel wireless audio system, and define unique machine code information for each extension speaker in the multi-channel wireless audio system. Among them, the unit code information is the system pairing code set by the manufacturer and stored in the MCU memory when the host speaker leaves the factory. It will be used for identification and pairing in the multi-channel wireless audio system, that is, the unit of different multi-channel wireless audio systems. The code information is different, only the host speaker and the extension speaker with the same code information can communicate. The machine code information is generally the receiving end authentication code set and stored in the MCU memory by the manufacturer when each extension speaker leaves the factory. It will be used for the identification (ID identification) and Control, that is, the extension speaker will be connected only when the control command of the host speaker has machine code information attached.
12)启动主机音箱和各分机音箱，主机音箱向其周围的分机音箱发送所在多通道无线音响系统的机组码信息。此步骤相当于一个初始化的步骤，确定同一多通道无线音响系统中的所有音箱。12) Start the host speaker and each extension speaker, and the host speaker sends the unit code information of the multi-channel wireless audio system where it is located to the surrounding extension speakers. This step is equivalent to an initialization step, identifying all speakers in the same multi-channel wireless audio system.
13)各分机音箱根据接收到的机组码信息判断自己是否处在该多通道无线音响系统，如果机组码信息相同，则向主机音箱发送其机器码信息；如果机组码信息不相同，则发送非同一多通道无线音响系统的响应信号，或者直接不响应。此步骤相当于在主机音箱中注册个各分机音的机器码信息，以便于后续的命令控制和信号传输。13) Each extension speaker judges whether it is in the multi-channel wireless audio system according to the received unit code information. If the unit code information is the same, it sends its machine code information to the host speaker; if the unit code information is different, it sends a non-identical Response signal of the same multi-channel wireless sound system, or simply not responding. This step is equivalent to registering the machine code information of each extension tone in the host speaker to facilitate subsequent command control and signal transmission.
14)主机音箱接收并保存每一个分机音箱的机器码信息。14) The host speaker receives and saves the machine code information of each extension speaker.
15)主机音箱对比接收到的各分机音箱反馈的机器码信息的个数与所在多通道无线音响系统的分机音箱的条数，如果一致，则断开连接；如果不一致，提示多通道无线音响系统出现故障，并断开连接。此步骤用于检验多通道无线音响系统中的各分机音箱是否正常工作，如果都正常工作，则主机音箱会受到所有的分机音箱的机器码信息15) The host speaker compares the number of machine code information received by each extension speaker with the number of extension speakers in the multi-channel wireless audio system. If they are consistent, disconnect the connection; if they are inconsistent, prompt the multi-channel wireless audio system Failed and disconnected. This step is used to check whether the extension speakers in the multi-channel wireless audio system work normally. If they all work normally, the main speaker will receive the machine code information of all the extension speakers.
二、依次测量各分机音箱相对于主机音箱的距离和位置，对每一分机音箱进行定位2. Measure the distance and position of each extension speaker relative to the host speaker in turn, and locate each extension speaker
21)主机音箱对接收到的机器码信息进行顺序排序。21) The host speaker sorts the received machine code information sequentially.
22)根据机器码信息逐个接通每一个分机音箱，测量各分机音箱相对于主机音箱的距离和位置，对每一分机音箱进行定位。22) Connect each extension speaker one by one according to the machine code information, measure the distance and position of each extension speaker relative to the host speaker, and locate each extension speaker.
下面仅以测试其中一个分机音箱的距离信息和位置信息为例作说明，其它的雷同。The following only takes the distance information and position information of one extension speaker as an example for illustration, and the others are the same.
首先，在主机音箱的左右两侧分别设置一个咪头，两咪头向背放置，轴线成180度，咪头设计在主机音箱箱体管道的内测，接收面指向箱体外部，即与空气直接接触，利于收集外表的声波。First of all, set a microphone on the left and right sides of the host speaker, and place the two microphones facing the back, with the axis at 180 degrees. Contact is good for collecting sound waves from the surface.
然后，由主机音箱向其中一个机器码信息的分机音箱发送一个距离测试命令。Then, the master speaker sends a distance test command to one of the extension speakers of the machine code information.
接着，该分机音箱根据接收并响应距离测试命令，并发出一定频率的声音信号，声音信号最佳为中频或者低频的声波信号。Then, the speaker of the extension unit sends out a sound signal of a certain frequency according to receiving and responding to the distance test command, and the sound signal is preferably a sound wave signal of a medium frequency or a low frequency.
最后，主机音箱根据左右两侧的咪头采集到的声音信号的音量大小判断该分机音箱相对于主机音箱的左、右位置，主机音箱根据咪头采集该声音信号所用的时间计算该分机音箱相对于主机音箱的距离，从而确定其相对于主机音箱的前、中或后的位置。Finally, the host speaker judges the left and right positions of the extension speaker relative to the host speaker based on the volume of the sound signals collected by the microphones on the left and right sides, and the host speaker calculates the relative position of the extension speaker based on the time it takes for the microphone to collect the sound signal. The distance from the main speaker to determine its front, middle or rear position relative to the main speaker.
其中，各分机音箱的距离测试和位置确定的步骤具体如下，如图3所示，Among them, the steps of the distance test and position determination of the speakers of each extension are as follows, as shown in Figure 3,
多通道无线音响系统的主机音箱(发送端)与各分机音箱(接收端)完成配对后，开始接通第一个分机音箱(接收端)的接收通道，给其一个要求产生声波信号的控制命令，同时启动定时器，声波信号控制命令经主机音箱发送出去，这段时间记录为T1；第一个分机音箱(接收端)接收到无线控制信号，这段时间记录为T2；分机音箱(接收端)控制DA输出音频信号，经分机音箱(接收端)的喇叭播放出去，这段时间记录为T3；咪头接收到来自分机音箱(接收端)发出的声音信号，这段时间记录为T4(由于两个)；分机音箱向主机音箱发出中断命令，同时关闭定时器，这段时间记录为T5，其中，定时器的整个定时时间总量为Ts，最后计算出来的发送端和接收端两点之间的时间T4，T4将用来计算主机音箱(发送端)与各分机音箱(接收端)之间的实际距离。After the host speaker (transmitter) of the multi-channel wireless audio system is paired with each extension speaker (receiver), start connecting the receiving channel of the first extension speaker (receiver), and give it a control command to generate a sound wave signal , and start the timer at the same time, the sound wave signal control command is sent out through the host speaker, and this time is recorded as T1; the first extension speaker (receiving end) receives the wireless control signal, and this time is recorded as T2; the extension speaker (receiving end) ) to control the DA to output audio signals, and play them through the speaker of the extension speaker (receiving end). This period of time is recorded as T3; the microphone receives the sound signal from the extension speaker (receiving end), and this period of time is recorded as T4 (due to Two); the extension speaker sends an interrupt command to the host speaker, and at the same time closes the timer. This period of time is recorded as T5, wherein the total timing time of the timer is Ts, and the final calculated difference between the two points of the sending end and the receiving end is Ts. The time T4 between, T4 will be used to calculate the actual distance between the host speaker (sending end) and each extension speaker (receiving end).
由于主机音箱上的两个咪头同时会接收来自分机音箱(接收端)发出的声音信号，本发明采用优先接收处理方式，主机音箱(发送端)只响应两个咪头中优先接收到声音信号并产生中断信号的一个。Because the two microphones on the main speaker can receive the sound signal from the extension speaker (receiving end) at the same time, the present invention adopts a priority receiving processing method, and the main speaker (sending end) only responds to the sound signal received preferentially from the two microphones. and generate one of the interrupt signals.
两个咪头接收到来自接收端(分机音箱)发出的声音信号后，经过处理分两路进行音量检测，咪头1的音量数据记录为V1，咪头2的音量数据记录为V2，最后计算出来的两个咪头的音量数据，将用来判断接收端(分机音箱)与发送端(主机音箱)所处的相对左右位置。After the two microphones receive the sound signal from the receiving end (extension speaker), they are processed and divided into two channels for volume detection. The volume data of microphone 1 is recorded as V1, and the volume data of microphone 2 is recorded as V2, and finally calculated The volume data of the two microphones will be used to judge the relative left and right positions of the receiving end (extension speaker) and the sending end (main speaker).
其中，主机音箱与该分机音箱两点之间的距离D＝340*T4米，T4＝Ts-(T5+T3+T2+T1)，两个咪头接收到的声音音量之差V＝V1-V2，当V大于0时，接收端与发送端的相对位置为左；当V小于0时，接收端与发送端的相对位置为右。综合测距和音量数据，首先通过判断音量大小得出相对左右位置信息，然后通过测距数据得出前、中、后相对位置信息，最终得出6个接收端(分机音箱)所属的声道信息。Among them, the distance between the two points of the host speaker and the extension speaker is D=340*T4 meters, T4=Ts-(T5+T3+T2+T1), the difference in the sound volume received by the two microphones is V=V1- V2, when V is greater than 0, the relative position of the receiving end and the sending end is left; when V is less than 0, the relative position of the receiving end and the sending end is right. Integrating the distance measurement and volume data, first obtain the relative left and right position information by judging the volume, then obtain the relative position information of the front, middle and rear through the distance measurement data, and finally obtain the channel information to which the 6 receivers (extension speakers) belong .
23)判断是否完成所有的机器码信息的分机音箱的定位，如果是，结束程序，否则，继续执行步骤21)，直至所有的分机音箱的定位完毕。23) Judging whether the positioning of all the extension speakers of the machine code information is completed, if yes, end the program, otherwise, continue to perform step 21) until the positioning of all extension speakers is completed.
三、根据每一个分机音箱的定位信息和机器码为其匹配适当的输出通道。3. Match the appropriate output channel for each extension speaker according to its positioning information and machine code.

3)按照分机音箱(接收端)机器码顺序接通第一个分机音箱(接收端)，经主机音箱(发送端)发出一个距离测试命令(产生声音命令)；3) Connect the first extension speaker (receiver) according to the machine code sequence of the extension speaker (receiving end), and send a distance test command (generate a sound command) through the host speaker (sending end);
4)分机音箱接收到无线信号后，经过处理发出一定频率的声音信号；4) After the extension speaker receives the wireless signal, it sends out a sound signal of a certain frequency after processing;
