Description

—种网络视频服务器 技术领域
本发明属于网络视频技术领域, 特别是涉及一种网络视频服务器。 背景技术
网络视频服务器是一种用于构建远程监控系统的设备, 被广泛用于安全监 控、交通监控、工业监控、家庭监控、视频会议和可视电话等众多领域。在视频 监控系统中,视频服务器起着核心的作用。人们使用视频服务器来组织管理每个 视频监控终端;对每个终端进行工作状态的控制;并且存储整个系统的视频和音 频图像。
在第一代和第二代的视频服务器的解决方案主要有两种, 一种是基于 PC架 构的视频服务器, 另一种是基于硬盘录像系统(DVR) 的方案。
基于 PC架构的视频服务器主要使用 PC板卡架构的视频压缩卡,根据不同的 需求可以录制到最多 64路图像, 但是厂家为了保证管理效果一般不会超过 16 路。软件方面一般采用 windows系统和应用程序。这样系统研发简单,软硬件厂 家可以分开研发, 系统架构快。但是也带来许多的问题:一是图像信号是用同轴 电缆来传, 音频信号要另外一路, 还有云台控制要另外一条电缆, 如果 16路那 会需要更多的电缆, 使布线和安装较为麻烦, 虽然最近有多芯电缆的方案, 但是 带来了其它的问题如各种信号干扰等;二是基于板卡的架构是多厂家配合,在软 硬件的稳定性上和操作系统的兼容性上总是会存在这样或那样的问题;三是这种 PC架构的本身的方案就是比较昂贵, 往往系统终端很便宜, 到视频服务器就把 整个系统的成本提升了。
第二种基于 DVR的方案也采用了类似 PC板卡的架构,不过把 PC主板部分更 改成嵌入式系统管理, 虽可降低内部存储器容量, 降低成本, 操作相对简单, 对 少量终端有一定的优势, 但是其布线和 PC架构并没有本质的差别; 而且, 虽然 使用了嵌入式系统性能比较稳定, 但是其研发周期相对较长, 技术门槛高。
随着网络技术的不断发展,现在视频监控已发展到了第三代, 即网络视频监 控系统。它的特点之一是图像和音频已经在摄像头终端处理成网络信号,意味着 视频服务器本身不必要对图像和音频进行处理,只要进行传输和存储。但是现有 的大部分的系统厂家在架构第三代网络摄像机系统时, 依然沿用了 PC的架构。 这样, 由于 PC架构的操作系统所带来的问题就不可避免, 而且这种网络视频服 务器的成本高, 体积大,耗电多, 噪声大, 必须用专用机房或地点, 而且部署也 很复杂。 发明内容
本发明的目的在于克服现有技术之不足,提供一种网络视频服务器,它采用 嵌入式的硬件架构, 并且使用 webserver进行管理,用基于浏览器操作界面,操 作终端不需要安装客户端软件,不需要安装驱动程序,可以实现随时随地监控和 查询的目的; 具有成本低, 体积小, 耗电少, 噪声小, 部署方便的特点。
本发明解决其技术问题所采用的技术方案是:一种网络视频服务器,它包括: 一个 CPU中央处理器,负责一切的数字和逻辑运算,控制和协调各部件的工 作;
一个 IDE/SATA硬盘接口, 用于挂载存储用的硬盘;
一个系统处理用的 SDRAM内存;
一个存储操作系统、 文件系统、 应用程序用的 FLASH存储器;
一个高速的以太网接口;
一个 IDE/SATA硬盘, 用于存储视频和音频文件;

具体实施方式
实施例一, 本发明的一种网络视频服务器, 如图 1所示, 它包括: 一个 CPU中央处理器 1, 负责一切的数字和逻辑运算, 控制和协调各部件的 工作;
一个 IDE/SATA硬盘接口 2, 用于挂载存储用的硬盘;
一个系统处理用的 SDRAM内存 3;
一个存储操作系统、 文件系统、 应用程序用的 FLASH存储器 4;
一个高速的以太网接口 5;
一个 IDE/SATA硬盘 6, 用于存储视频和音频文件;

由于第三代网络摄像机的特点是图像和音频已经在摄像头终端处理成网络 信号,因而,第三代网络视频服务器就可以只承担着视频和音频的文件的存储和 回放的任务。 硬件性能要求有足够的网络带宽和硬盘存储速度即可。
参见图 2所示,本发明的网络视频服务器,使用在视频监控系统中,作为基 本的组网方案,网络视频服务器 10通过以太网接口即 RJ45接口与路由器和交换 机 11相连接, 路由器和交换机 11接入 INTERNET互联网 12, 外部网络摄像机终 端 13 (若干个)通过 RJ45接口和路由器和交换机 11连接, 把网络监控信号通 过网络传输到网络视频服务器 10, 同时接收和响应视频服务器 10的各种请求指 令。
本发明的网络视频服务器, 系统内置了以太网交换电路(图中未示出), 以 太网交换电路与中央处理器相连接。图 3为本发明的网络视频服务器的扩展组网 方式, 由于有了以太网交换电路,利用以太网交换电路提供的四个外部以太网接 口, 网络视频服务器 10可以向上连接以太网交换机 11, 同时还可以连接其它的 网络设备 14如 PC机、另外的交换机、网络摄像机等,保证以太网中继交换功能 的实现, 适合复杂的网络拓扑。
本发明的网络视频服务器, 还可包括音频接口 (AC97或 1¾接口)、 USB接 口、 PCI接口、 I2C接口、 VGA接口、 串口等, 以便扩展其它功能。 扩展了 USB 总线接口电路以便外接其它的 USB设备;扩展了串口电路用于系统调试;扩展了 1 电路以便外接 C设备; 扩展了音频接口 (AC97或 1¾接口) 以便输出和输 入音频信号; 扩展了 PCI总线以便外接其他的 PCI设备; 扩展了 PCMCIA接口以 便外接 PCMCIA接口设备; 另外具备通用 I/O用于外接 I/O设备。
本发明的网络视频服务器,通常采用 S0C系统集成芯片来实现硬件架构, S0C 系统集成芯片可以是单颗 SOC (system on chip); 也可以是由各种芯片组成的芯 片模组, 如 S0C芯片中集成有 USB总线接口、 串口电路、音频接口、 PCI总线接 口等。参见图 7所示, 本实施例的 S0C系统集成芯片 100, 分别集成了 CPU中央 处理器 1、 IDE/SATA硬盘接口 21, 以太网 MAC电路 511、 USB总线接口、 串口电 路、音频接口(AC97或 1¾接口)、 PCI总线、 I2C电路、 PCMCIA接口、通用 I/O、 VGA/LCD控制器、 SDRAM控制器、 FLASH控制器, 并分别通过系统总线相连接。 SDRAM控制器与 SDRAM内存 3相连接; FLASH控制器与 FLASH存储器 4相连接; 1¾接口电路与实时时钟电路 31相连接, 由于要保证视频服务器运行的时钟准 确,在断电一段时间恢复后要保证时间准确, 所以必须有外接的时间信号源,虽 然可以采用国际通行的时间服务器方案,但是考虑到如果断电时找不到时间服务 器,而这时候又有录制要求, 因此系统有个可以断电运行的时钟源是必须的, 因 而利用了系统上的 1 总线, 挂载了 1¾总线接口传输的实时时钟芯片, 并且实 时时钟电路 31上连接后备电源(图中未示出),使用小型电池来保证在断电时时 钟的正常运行; 通用 I/O与 LED指示器相连接; IDE/SATA硬盘接口 2采用集成 在 S0C系统集成芯片 100内的 IDE/SATA硬盘接口电路 21 , IDE/SATA硬盘接口电 路 21与 IDE/SATA硬盘 6相连接, 硬盘 6通过 S0C芯片 100上的硬盘接口电路 21和 S0C芯片 100的系统总线连接来接收要存储信号, 这种硬盘接口构架方式 的特点是硬盘 6直接挂接在芯片上,和芯片 DMA控制器结合传输速度快,电路简 洁;本发明的网络视频服务器是采用以太网接口 5实现网络信号传输,在网络信 号传输介质上, 目前主要有以太网的 RJ45, 无线, 光纤三种, 有线接口协议规 范遵循 IEEE802. 3x, 无线部分遵循 IEEE802. llx, 而对于以太网线 RJ45接口, 分别可以采用光纤接口、 802. 1 无线射频接口电路来替换, 本实施例的以太网 接口 5为集成在 S0C系统集成芯片 100内的以太网 MAC接口电路 511和与 MAC 接口电路相连接的以太网 PHY电路芯片 512,在大多数有网络应用功能的 S0C芯 片都集成以太网 MAC (介质访问控制—— medium access control) 电路, 这时 候我们只要外接一个以太网 phy (物理层设备 Physical Layer Device, PHY)芯片, 监控信号就可以通过芯片的以太网接口接入相应的以太网系统,这种网络接口的 架构方式由于以太网的 MAC层电路直接集成在芯片内部, 和系统的总线相联系, 传输速度最快, 外部只要有一 PHY芯片就可以了, 成本低廉。
本发明的网络视频服务器的软件架构包括操作系统和软件,其中,操作系统 采用了流行的 linux嵌入式操作系统,网络功能强大,内置主流的各种网络协议, 并且软件资源丰富,在此操作系统下许多硬件的驱动程序不需要重新编写,移植 或直接使用既可; 使用 linux操作系统视频服务器的架构简单, 网页编写简单, 利用现有的 PC— linux相应的技术就可以实现,实现和 PC架构视频服务器相应的 性能; 如果采用其他类型的操作系统,也可以达到相应的效果, 但是研发的速度 和易用性不如用 linux。
其软件构成参见图 4所示, 包括:
作为软件核心和基础的 Embeded OS嵌入式操作系统; 用于各种总线接口和硬件电路的 Driver驱动程序;
用于全部应用程序的协议的 TCP/IP基本网络协议和 RTP/RTCP扩展协议; 用于提供外部对视频服务器的服务的 webserver网络服务程序;
作为诸多小型应用程序的集合的 configure配置程序;
实现数据及指令发送的 SendData发送程序;
实现数据及指令接收的 ReceiveData接收程序;
便于访问者可以用普通 PC通过浏览器进行访问视频服务器中的内容的 HTML 访问的网页界面程序。
使用过程中, 外部网络监控信号通过以太网芯片 512上的 RJ45接口把指令 由以太网传输到 S0C芯片 100内部,通过 S0C系统总线传输到系统的应用程序中, 经过系统应用程序处理后把监控信号通过系统中的 IDE/SATA接口 21存入外部的 硬盘 6。
参见图 5所示,本发明的网络视频服务器,在数据接收时:从摄像机列表中 读取摄像机地址信息; 连接摄像机; 请求视频数据; 接收数据; 接收失败时返回 重新连接摄像机; 接收成功时将数据写入硬功夫盘; 返回继续接收数据。
参见图 6所示, 本发明的网络视频服务器, 在数据发送时: 监视连接请求; 验证用户是否合法; 不合法拒绝连接; 合法接受连接; 接受发送数据指令; 根据 指令要求发送数据。
实施例二, 参见图 8所示,本发明的一种网络视频服务器,与实施例一的不 同之处在于, S0C系统集成芯片 100内没有集成硬盘接口电路,此时可以利用 S0C 系统集成芯片 100内的 PCI总线接口 221来实现与 IDE/SATA硬盘 6的连接。 在 这种硬盘接口架构中, IDE/SATA硬盘接口 2为集成在 S0C系统集成芯片内的 PCI 接口电路 221 和与 PCI接口电路相连接的 IDE/SATA转 PCI 电路芯片 222, IDE/SATA转 PCI电路芯片 222与 IDE/SATA硬盘 6相连接, PCI接口电路 221在 S0C系统集成芯片 100内通过系统总线与 CPU中央处理器 1相连接, 监控信号通 过 IDE/SATA转 PCI电路芯片 222传输到硬盘 6里面, 这种硬盘接口架构比起实 施例一的电路多用了一颗桥接芯片 222, 传输速度和实施例一方案相当。

实施例五, 参见图 11所示, 本发明的一种网络视频服务器, 与实施例一的 不同之处在于, S0C系统集成芯片 100内没有集成以太网 MAC接口电路, 此时可 以利用 S0C系统集成芯片 100内的 PCI总线接口 551来实现与外部以太网系统的 连接,在这种以太网接口 5架构中, 以太网接口 5为集成在 S0C系统集成芯片内 的 PCI接口电路 551和与 PCI接口电路相连接的 PCI接口的以太网电路芯片 552, PCI接口的以太网电路芯片 552与外部以太网系统 7相连接, PCI接口电路 551 在 S0C系统集成芯片 100内通过系统总线与 CPU中央处理器 1相连接,监控信号 通过 PCI接口的以太网电路芯片 552接入外部的以太网系统 7,这种以太网接口 架构比起实施例一的电路多用了一颗桥接芯片 552, 由于 PCI接口的以太网芯片 552在 PC里大量使用, 因此方案的选择多, 而且软件的驱动程序直接可以从 PC 移植过来。
对于无线和光纤传输来说,上述的以太网接口 5都有相应的无线芯片或等效 电路可以替换。 实施例六, 参见图 12所示, 本发明的一种网络视 服务器, 与实施例一的 不同之处在于, S0C系统集成芯片 100内没有集成以太网 MAC接口电路, 此时可 以利用 S0C系统集成芯片 100内的 PCMCIA接口电路 561来实现与外部以太网系 统 7的连接,在这种以太网接口 5架构中, 以太网接口 5为集成在 S0C系统集成 芯片内的 PCMCIA接口电路 561和与 PCMCIA接口电路相连接的 PCMCIA接口的以 太网电路芯片 562, PCMCIA接口的以太网电路芯片 562与外部以太网系统 7相连 接, PCMCIA接口电路 561在 S0C系统集成芯片 100内通过系统总线与 CPU中央 处理器 1相连接, 监控信号通过 PCMCIA接口的以太网电路芯片 562接入外部的 以太网系统 7, 这种以太网接口架构, 由于 PCMCIA接口的以太网网卡 562不论 有线还是无线在笔记本电脑里已经大量应用,作为一种便携式设备它的特点是省 电, 并且也有大量的软硬件资源可以利用。
对于无线和光纤传输来说,上述的以太网接口 5都有相应的无线芯片或等效 电路可以替换。
实施例七, 参见图 13所示, 本发明的一种网络视频服务器, 与实施例一的 不同之处在于, S0C系统集成芯片 100内没有集成以太网 MAC接口电路, 此时可 以利用 S0C系统集成芯片 100内的 USB接口电路 571来实现与外部以太网系统 7 的连接,在这种以太网接口 5架构中, 以太网接口 5为集成在 S0C系统集成芯片 内的 USB接口电路 571和与 USB接口电路相连接的 USB接口的以太网电路芯片 572, USB接口的以太网电路芯片 572与外部以太网系统 7相连接, USB接口电路 571在 S0C系统集成芯片 100内通过系统总线与 CPU中央处理器 1相连接,监控 信号通过 USB接口的以太网电路芯片 572接入外部的以太网系统 7,作为一个新 的设备 USB接口以太网卡 572已经在市场上大量应用,不论有线还是无线我们都 可以有大量资源可以利用。

上述实施例仅用来进一步说明本发明的网络视频服务器,但本发明并不局限 于实施例,凡是依据本发明的技术实质对以上实施例所作的任何简单修改、等同 变化与修饰, 均落入本发明技术方案的保护范围内。
