PoE++会用到哪里？它会变得普遍寻常吗？

我已经建立了一个客户机/服务器板来发送音频从一个建筑物到另一个建筑。音频传输每天大约20-25次。它用于发送语音页面到远程大楼中的扬声器。它已经使用了几个星期，效果很好。基本上，我所做的就是向远程建筑传输UDP。远程建筑是服务器，传输来自主楼的客户端，主楼的原始音频通过PIC上的ADC输入转换成数字信号。我的转换率是8千赫和音频听起来不错。数字信号在PIC上发送USAT（230400 BPS），并通过USRIO数据UR—K2模块转换为以太网。在远端，URR K2将以太网信号转换回PICUSAT接收到的RS232，并落到PIC DAC上。DAC的输出驱动一个放大器来驱动扬声器的放大器。我正在考虑设置一些东西来处理一个以上的远程建筑。例如，可能有三个需要被分页的远程建筑。我可以在主楼和每个远程建筑的服务器上安装三个客户。这是可行的，但是使用三个客户端意味着三个单独的硬件。这是最简单的答案吗？或者有一种方式，音频可以发送到三个不同的服务器在同一时间？我唯一能想到的解决方案是在主建筑上拥有服务器，在偏远建筑上拥有客户。如果我这样做的话，假设我必须从UDP转换到TCP，保持生存状态，这是正确的吗？我现有的硬件使用PIC16F1718来驱动UsRIO模块。我正在考虑删除UsRIO模块，并用PIC32做所有的事情。PIC32也会给我更多的RAM来缓冲链接两端的音频。 以上来自于百度翻译 以下为原文 I have built a client/server pair of boards to send audio from one building to another building. The audio transmissions occur about 20-25 times per day. It is used for sending a voice page to overhead speakers in the remote building. It has been in use for several weeks and it works fine. Basically all I am doing is an UDP transmission to the remote building. The remote building is the server and the transmission comes from the client at the main building.The originating audio at the main building is converted to a digital signal using an ADC input on the PIC. My conversion rate is 8 KHz and the audio sounds good. The digital signal is sent out the USART (230400 bps) on the PIC and is converted to Ethernet by a USRIO Data USR-K2 module. At the remote end, the USR-K2 converts the Ethernet signal back to RS232 which the PIC USART receives and drops onto the PIC DAC. The output from the DAC drives an opamp which drives the amplifier for the speakers.I am thinking about setting something up to handle more than one remote building. For instance, there could be three remote buildings that would need to be paged. I could setup three clients at the main building and a server at each of the remote buildings. This would work but using three clients means three separate pieces of hardware.Would this be the easiest answer? Or is there a way that the audio could be sent to three different servers at one time? The only solution I have been able to think of is the have the server at the main building and clients at the remote buildings. Am I correct in assuming that I would have to change from UDP to TCP with keep alive running if I do this?My existing hardware uses a PIC16F1718 to drive the USRIO modules. I am considering eliminating the USRIO modules and doing everything with a PIC32. The PIC32 would also give me more RAM for buffering the audio at each end of the link.

大家好，借贵宝地盖盖楼，呵呵。 本人写了大量的omap3 kernel的注释包括电源管理以及各个模块的核心实现以及驱动，现在想整理成书，各方面资料准备基本完成，开始写的话应该2个月左右能完场。感兴趣的请回复。盖楼到100就开始写。谢谢。
