Embodiment 1

[0078] Embodiment 1: Data backup scheme

[0079] Figure 7 is a schematic diagram of implementing a data backup solution according to an embodiment of the present invention, such as Figure 7 Shown:

[0080] Assume that device A and device B are in normal operation, that is, the devices are powered by power lines and use Ethernet to transmit data; network message, then A device sends a detection message, which requires B device to respond and respond. The transmission link fails or is disconnected. At this time, device A and device B cannot receive each other's data. At the same time, device B also performs the same detection operation. The data switching control module transfers the data according to the data backup protection rules. The link is switched from E to F. After the data link is switched, device A and device B first perform a communication handshake to confirm the status before and after the switch. If the status of devices A and B is confirmed to have switched ...

Embodiment 2

[0082] Embodiment 2: Power backup scheme

[0083] Figure 8 is a schematic diagram of implementing a power backup solution according to an embodiment of the present invention, such as Figure 8 Shown:

[0084] Assume that during the normal operation of equipment A and equipment B, there is a problem with the power supply of equipment B, such as power failure or low voltage (there is a detection circuit in the power module, the voltage is normal in a certain range, and the voltage exceeds the range Alarm), the power supply module has the function of detecting the power supply of the equipment, if it is detected that the power supplied by C to the equipment exceeds the normal range, it will send an alarm message to the data processing module; the alarm signal controls the power switch at the same time, switches the power supply, and equipment B The power supply of the power supply module in the center will be switched from the power provided by C to the power provided by D. T...

Embodiment 3

[0085] Embodiment 3: Simultaneous backup scheme of power supply and data

[0086] Figure 9 is a schematic diagram of a simultaneous power and data backup solution according to an embodiment of the present invention, as shown in Figure 9 As shown: the present invention can realize switching backup protection of data and power of the equipment at the same time, that is, the comprehensive backup scheme of Embodiment 1 and Embodiment 2.

Abstract

The present invention discloses a method, an apparatus and a system for backup of a link and a power supply. The method comprises the steps of: monitoring whether a POE (Power over Ethernet) transmission link between two devices is normal; in the case of monitoring that the POE transmission link is abnormal, switching the POE transmission link to a BPL (Broadband over Power Lines) communication link; and transmitting data between the two devices through the BPL communication link, thereby achieving backup of a data communication link. At the same time, in the case that a power supply of a power line is abnormal, the method executes the step of switching to a POE power supply mode, thereby achieving backup of the power supply. The method, the apparatus and the system of the present invention solve the problem that a traditional backup protection scheme does not facilitate cost saving and energy saving in the correlation technology, as a traditional backup protection system needs two sets of equipment and the system in the present invention only needs one set of equipment to achieve a backup function, cost is saved; in addition, the system is beneficial to energy saving and environmental protection; and the system is easy to implement and does not need to erect base facilities such as lines again, thereby saving cost.

Description

technical field [0001] The invention relates to the communication field, in particular to a link backup and power backup method, device and system. Background technique [0002] With the rapid development of communication technology, broadband power line communication has been widely used. It utilizes the existing power network and uses power line as a new type of information transmission medium to realize signal transmission. The application of Ethernet transmission has been quite mature, and Ethernet can provide power while transmitting signals, and it has also been developed and applied in recent years, that is, the active Ethernet technology POE (PoweroverEthernet). [0003] The power line broadband technology BPL (Broadband over powerlines) is a technology that allows Internet data to be transmitted on the power line, which can effectively reduce wiring costs. People often refer to BPL as power line communication PLC. [0004] POE refers to the connection between some...
