技术领域
本申请涉及监控领域，特别涉及一种摄像机状态获取方法、摄像机及摄像机系统。
背景技术
当前，在小区、街道等人员活动密集区域安装监控设备已经成为保障人民群众安全、震慑不法分子的重要手段。
在实际应用中，为了便于后续安装监控设备，小区、街道等在施工建造的过程中就会在地下埋设监控网线，监控设备安装之后即可通过地下埋设的监控网线实时上传监控视频。然而，一些建成时间较早的小区、街道，以及农村等偏远区域的地下并没有预先埋设监控网线，因此，若要在这些地方安装监控设备就要涉及到线路改造，其成本较高。为了降低成本，在上述一些建成时间较早的小区、街道，以及农村等偏远区域中，通常可以利用带有存储功能的摄像机来实现监控，带有存储功能的摄像机不需要通过监控网线实时上传拍摄的监控视频，而是将其存储起来，技术人员可以在需要获取监控视频时，再对监控视频进行提取。在实际应用中，为了保证监控可靠，技术人员需要定期检测上述摄像机的状态，如检测摄像机的摄像组件是否正常工作，存储组件是否损坏等。
相关技术中，上述摄像机中可以安装无线网卡，该无线网卡可以广播无线信号，技术人员检测摄像机状态时，可以通过该无线网卡广播的无线信号与摄像机建立通信连接，以访问摄像机，获取摄像机的状态。
由于无线网卡广播的无线信号传输距离有限，因此，技术人员在检测摄像机状态时，需要到每一台摄像机附近进行操作，维护成本较高。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
图1是本申请实施例提供的一种摄像机系统，如图1所示，该摄像机系统可以包括一个第一摄像机110和至少一个第二摄像机120。第一摄像机110和第二摄像机120可以均为带有存储功能的摄像机，也即是，第一摄像机110和第二摄像机120中均可以设置有存储组件，例如，该存储组件可以为存储卡或硬盘等。
在图1所示的摄像机系统中，第一摄像机110和每一个第二摄像机120之间均可以通过第一无线网络建立有通信连接，此外，第一摄像机110和云端服务器S之间还可以通过第二无线网络建立有通信连接，其中，第一无线网络可以为无线局域网，第二无线网络可以为无线广域网。在实际应用中，第一摄像机110可以通过与第二摄像机120间的通信连接获取第二摄像机120的状态信息，并将该状态信息通过与云端服务器S间的通信连接发送至云端服务器S中。这样，技术人员通过访问云端服务器S就可以获取摄像机系统中的摄像机的状态信息，从而降低了对摄像机的维护成本，此外，由于不同的摄像机系统中的第一摄像机110可以向同一云端服务器S发送摄像机的状态信息，因此，本申请实施例可以针对多个摄像机系统部署一台云端服务器S，这样可以降低硬件部署成本，从而降低摄像机的维护成本。
需要说明的是，在实际应用中，技术人员可以在小区、村庄等区域中架设一台或多台同时带有广域网通信功能和局域网通信功能的摄像机作为上述第一摄像机110，并在该区域中架设多台具有局域网通信功能的摄像机作为上述第二摄像机120。其中，第一摄像机110被配置为能够广播自身的网络信息，而第二摄像机120被配置为能够通过响应上述网络信息从而加入第一摄像机110所在的第一无线网络，或者，第二摄像机120被配置为能够广播请求加入网络信息，而第一摄像机110被配置为能够通过响应上述请求加入网络信息而允许第二摄像机120加入第一摄像机110所在的第一无线网络。在实际应用中， 每一第二摄像机120均可以加入一个第一摄像机110所在的第一无线网络，以与该第一摄像机110组成如图1所示的摄像机系统。
当然，在实际应用中，上述区域中架设的所有摄像机可以均为同时带有广域网通信功能和局域网通信功能的摄像机，在这种情况下，云端服务器可以向上述任一个或多个摄像机发送激活指令，并将接收到激活指令的摄像机作为第一摄像机110，而其他的摄像机作为第二摄像机120。与上文叙述同理地，该第一摄像机110被配置为能够广播自身的网络信息，而第二摄像机120被配置为能够通过响应上述网络信息从而加入第一摄像机110所在的第一无线网络，或者，第二摄像机120被配置为能够广播请求加入网络信息，而第一摄像机110被配置为能够通过响应上述请求加入网络信息而允许第二摄像机120加入第一摄像机110所在的第一无线网络。在实际应用中，每一第二摄像机120均可以加入一个第一摄像机110所在的第一无线网络，以与该第一摄像机110组成如图1所示的摄像机系统。
图2是本申请实施例提供的一种第二摄像机120的结构框图，如图2所示，该第二摄像机120可以包括摄像组件1201、存储组件1202、摄像机处理器1203和局域网通信组件1204。其中，摄像机处理器1203与摄像组件1201、存储组件1202和局域网通信组件1204分别相连，摄像组件1201与存储组件1202相连。上述摄像组件1201用于拍摄监控视频；存储组件1202用于存储摄像组件1201拍摄的监控视频；摄像机处理器1203用于获取第二摄像机120的状态信息，如摄像组件1201的工作状态、存储组件1202的工作状态和监控视频拍摄时长等；摄像机处理器1203还用于将第二摄像机120的状态信息发送至局域网通信组件1204中；第二摄像机120可以利用局域网通信组件1204与第一摄像机110通过第一无线网络建立通信连接，并通过局域网通信组件1204接收第一摄像机110下发的状态获取指令，以及通过局域网通信组件1204将第二摄像机120的状态信息发送至第一摄像机110中。
在实际应用中，局域网通信组件1204可以通过UART(Universal  Asynchronous Receiver/Transmitter，通用异步收发传输器)接口、USB(Universal Serial Bus，通用串行总线)接口、SPI(Serial Peripheral Interface，串行外设)接口或I2C(Inter－Integrated Circuit，两线式串行总线)接口等与摄像机处理器1203连接，也即是，局域网通信组件1204可以可拆卸地设置于第二摄像机120中，并可以支持热插拔，因此，当局域网通信组件1204出现故障时可以方便地对其进行更换。
在本申请的一个实施例中，上述局域网通信组件1204可以为LORA(Long Range，长距离)通信组件，上述第一无线网络可以为LORA通信网络。由于LORA通信信号传输距离较长(通常可为几千米左右)，因此，一个摄像机系统可以覆盖一个小区或一个村庄中架设的所有摄像机，这样，一方面，可以尽量少地部署第一摄像机，由于第一摄像机除了具有局域网通信功能外，还需要具有广域网通信功能，其相较于只具有局域网通信功能的第二摄像机而言成本较低，因此，少部署第一摄像机可以降低摄像机系统的部署成本，另一方面，由于LORA通信信号传输距离较长，因此，在摄像机系统中可以不需要部署中继设备，这也能降低摄像机系统的部署成本。当然，在实际应用中，上述局域网通信组件1204还可以为其他类型的通信组件，上述第一无线网络也可以为其他类型的通信网络，本申请实施例对此不作具体限定。
下面，本申请实施例仅以局域网通信组件1204为LORA通信组件为例进行说明。如图3所示，该LORA通信组件可以包括依次连接的LORA收发芯片12、切换芯片13和天线14。其中，天线14用于接收或发射LORA通信信号；切换芯片13用于切换LORA通信组件的通信状态，其中，该通信状态可以为发射状态或接收状态；LORA收发芯片12用于对天线14接收到的LORA通信信号转化的电信号进行处理，并用于生成电信号以使天线14将该生成的电信号转化为LORA通信信号发射出去。在实际应用中，该LORA通信组件还可以包括通信处理器11，该通信处理器11可以与摄像机处理器1203和LORA收发芯片12分别连接，其用于分别与摄像机处理器1203和LORA收发 芯片12进行通信。
在实际应用中，通信处理器11可以为单片机，当其为单片机时，其可以通过SPI接口、DIO(Digital Input and Output；数字输入输出)接口和RST(Intel Rapid Storage Technology，英特尔快速存储)接口与LORA收发芯片12连接。通信处理器11可以通过SPI接口驱动该LORA收发芯片12，可以通过DIO接口响应LORA收发芯片12的通信事件，可以通过RST接口对LORA收发芯片12进行复位。
图4是本申请实施例提供的一种第一摄像机110的结构框图，如图4所示，该第一摄像机110可以包括摄像组件1101、存储组件1102、摄像机处理器1103、局域网通信组件1104和移动数据通信组件1105。其中，摄像机处理器1103与摄像组件1101、存储组件1102、局域网通信组件1104和移动数据通信组件1105分别相连，摄像组件1101与存储组件1102相连。第一摄像机110中的摄像组件1101、存储组件1102的用途、结构等与上文叙述的第二摄像机120中摄像组件1201、存储组件1202的用途结构同理。
第一摄像机110可以利用局域网通信组件1104和第二摄像机120通过第一无线网络建立通信连接，可以通过局域网通信组件1104接收第二摄像机120发送的状态信息，也可以通过局域网通信组件1104向第二摄像机下发状态获取指令。需要说明的是，局域网通信组件1104的结构与上文所述的局域网通信组件1204的结构同理，也即是，局域网通信组件1104也可以为LORA通信组件。
摄像机处理器1103用于获取第一摄像机110的状态信息，摄像机处理器1103还用于获取第一摄像机110通过局域网通信组件1104接收到的第二摄像机120的状态信息，摄像机处理器1103还可以将第一摄像机110和第二摄像机120的状态信息发送至移动数据通信组件1105中。
第一摄像机110可以利用移动数据通信组件1105与云端服务器S通过第二无线网络建立通信连接，第一摄像机110可以通过移动数据通信组件1105 将第一摄像机110和第二摄像机120的状态信息发送至云端服务器S中，其中，该第二无线网络可以为移动通信网络。
在本申请的一个实施例中，该移动数据通信组件1105可以为4G(the 4th Generation mobile communication，第四代移动通信技术)通信组件、3G(the 3th Generation mobile communication，第三代移动通信技术)通信组件等，本申请实施例对此不做具体限定。
