From a business perspective, voice services and emergency services are important services, and the reliability requirements are very high. Even if the system is powered off, voice services and emergency services must be able to work normally for a certain period of time to ensure security monitoring in the home. When a user has an emergency, they can get help in time by phone.

The independent power supply is used for power supply. The independent power supply is more reliable than the user's home. Even when the local power supply in the user's home is powered off, the head end equipment can also be powered. The head end equipment passes the voltage of the independent power supply. Transforming produces a remote supply voltage, which is DC or 氐 frequency AC. The head end device couples the generated remote power supply voltage to the coaxial cable of the coaxial network for transmission, so that the terminal device of the coaxial network acquires the remote power supply voltage as the power supply voltage of the terminal device, and supplies power to the terminal device.
在同轴网络中, 终端设备获取耦合于同轴电缆上的远程供电电压, 该远程供电电压; 终端设备获取远程供电电压后, 将远程供电电压作为 供电电源。  In the coaxial network, the terminal device acquires a remote power supply voltage coupled to the coaxial cable, and the remote power supply voltage; after the terminal device acquires the remote power supply voltage, the remote power supply voltage is used as the power supply.

The remote power supply voltage is used as a power supply to supply power to the terminal device, thereby realizing power supply to the terminal device by using a stable power source in the head end device. In the coaxial network, in the process of supplying power to the terminal device through the remote power supply voltage in the coaxial cable, in order to enable the terminal device to implement the service, the method further includes:
头端设备产生数据信号, 并通过所述同轴网络发送所述数据信号。 所述业务, 包括作为重要业务的语音业务和紧急业务, 以及作为非 重要业务的数据业务和视频业务。  The headend device generates a data signal and transmits the data signal over the coaxial network. The services include voice services and emergency services as important services, and data services and video services as non-essential services.
其中, 在同轴网络的同轴电缆中, 实现业务的数据信号, 一般为 5 兆赫兹(MegaHertz, 以下简称 MHz )到 1吉赫兹( GigaHertz, 以下简 称 GHz ) 的模拟信号。 实际应用时, 头端设备产生远程供电电压和数据信号, 并通过同轴 网络中的同轴电缆进行传输; 其中远程供电电压为直流电或低频交流 电, 数据信号为高频电信号; 通过终端设备对同轴电缆中的远程供电电 压和数据信号进行滤波, 分别获取远程供电电压和数据信号; Among them, in the coaxial cable of the coaxial network, the data signal for realizing the service is generally an analog signal of 5 megahertz (MegaHertz, hereinafter referred to as MHz) to 1 GHz (Gigahertz, hereinafter referred to as GHz). In practical applications, the head end equipment generates remote power supply voltage and data signals, and transmits them through a coaxial cable in a coaxial network; wherein the remote power supply voltage is direct current or low frequency alternating current, and the data signal is a high frequency electrical signal; The remote power supply voltage and the data signal in the coaxial cable are filtered to obtain the remote power supply voltage and the data signal respectively;
在终端设备获取远程供电电压时, 该远程供电电压的电压值较高, 无法直接进行使用; 故在终端设备中, 需要对作为供电电源的远程供电 电压进行变压, 以使远程供电电压适用于终端设备, 进而对终端设备进 行供电。  When the terminal device obtains the remote power supply voltage, the voltage value of the remote power supply voltage is high and cannot be directly used; therefore, in the terminal device, the remote power supply voltage as the power supply source needs to be transformed so that the remote power supply voltage is suitable for The terminal device, in turn, supplies power to the terminal device.
终端设备获取数据信号后, 在解析后实现对应的业务。 举例来说, 头端设备通过同轴电缆发送的数据信号, 包括需要终端设备执行视频业 务所需要的数据; 终端设备通过直流滤波获取同轴网络中的数据信号, 对该数据信号进行解析后执行视频业务。  After the terminal device obtains the data signal, the corresponding service is implemented after parsing. For example, the data signal sent by the head end device through the coaxial cable includes data required for the terminal device to perform video service; the terminal device acquires the data signal in the coaxial network by DC filtering, and parses the data signal to execute Video business.
头端设备通过在同轴网络中的同轴电缆上耦合的远程供电电压对 终端设备进行供电时, 通过同轴电缆传输数据信号, 使终端设备在实现 业务, 从而在终端设备在远程供电的情况下保证业务实现的可靠性。 对于设置于用户家中的终端设备, 因可能同时执行多个业务, 从而 消耗较大的电能, 当同轴网络中同时对多个终端设备进行远程供电时, 会造成头端设备的功率消耗过大, 从而损坏头端设备; 为避免上述问题, 可选的, 在所述将所述远程供电电压作为所述终端设备的供电电源为所 述终端设备供电之前, 还包括:  When the head end device supplies power to the terminal device through a remote power supply voltage coupled on the coaxial cable in the coaxial network, the data signal is transmitted through the coaxial cable, so that the terminal device realizes the service, and thus the terminal device is remotely powered. The reliability of the business implementation is guaranteed. For a terminal device installed in a user's home, it is possible to perform a plurality of services at the same time, thereby consuming a large amount of power. When the plurality of terminal devices are simultaneously powered remotely in the coaxial network, the power consumption of the head end device is excessive.

At this time, the terminal device performs important services and non-essential services, and the non-essential services include: data services and video services, where the important services include: voice services and emergency services. When the local power supply in the user's home is powered off, the terminal device cannot detect the local power supply voltage, then switches the remote power supply voltage obtained by the terminal device, and supplies power to the terminal device by transforming the remote power supply voltage. When the terminal device performs the power supply between the remote power supply and the local power supply, the terminal device is preferably powered by the local power supply when the local power supply of the user's home is normal. When the local power supply in the user's home is powered off, the head is passed. The terminal device performs remote power supply, thereby reducing the power consumption of the head end device, avoiding the damage of the head end device, and improving the reliability of the terminal device service execution in the coaxial network.
当同轴网络中存在多个终端设备时, 为进一步降低终端设备在通 过头端设备远程供电时功率消耗, 可选的, 在所述切换使用所述远程 供电电压之后, 还包括: When there are multiple terminal devices in the coaxial network, in order to further reduce power consumption when the terminal device is remotely powered by the head end device, optionally, after the switching uses the remote power supply voltage, the method further includes:

在用户家中的本地供电电源断电后, 终端设备切换使用头端设备所 提供的远程供电电压, 经过变压后对终端设备进行供电; 此时, 终端设 备继续获取同轴网络的同轴电缆中所传输的数据信号, 并进行解析; 在 通过解析后的数据信号执行相关的业务时, 因处于远程供电的状态, 终 端设备放弃执行非重要业务, 执行重要业务, 从而减少了终端设备的所 消耗的功率, 继而降低了头端设备的功率消耗, 避免了头端设备因功率 消耗过大而造成的损坏, 提升了终端设备在用户家中断电的情况下语音 业务和紧急业务等重要业务执行的可靠性。 与上述一种同轴网络的远程供电方法相对应, 本发明还提供了一种 头端设备, 如图 2所示, 包括:  After the local power supply in the user's home is powered off, the terminal device switches to use the remote power supply voltage provided by the head end device, and after the voltage transformation, powers the terminal device; at this time, the terminal device continues to acquire the coaxial cable of the coaxial network. The transmitted data signal is parsed; when the related data is executed by the parsed data signal, the terminal device abandons the execution of the non-essential service and performs the important service due to the remote power supply state, thereby reducing the consumption of the terminal device. The power, which in turn reduces the power consumption of the head end equipment, avoids the damage caused by the excessive power consumption of the head end equipment, and improves the execution of important services such as voice service and emergency service when the terminal equipment is interrupted by the user's home. reliability.
