the server comprises a control module and a storage module; the control module is used for setting part of the plurality of user nodes as user relay nodes according to the historical data transmission records of the user nodes and the size of the storage space of the user nodes; the control module is also used for judging whether a power failure event occurs in advance according to the real-time data transmission rate of the user node connected with the control module and the content of the data, and sending an emergency power failure warning to the user node in the corresponding area when the power failure event is determined to be an emergency power failure event;
the storage module is used for storing the data information sent by the user node and the service information of all the user nodes connected with the user node;
the user node comprises a detection module, a communication module and a cache unit; the communication module is used for converting a communication protocol and executing communication with other user nodes and servers; the detection module is used for receiving the data sent by the communication module and executing data acquisition, and is also used for detecting the signal of an alternating current power supply at the front end of the user node and judging whether a power failure event occurs or not;
the cache unit is used for storing data, and when the power failure signal sent by the detection module is received, the cache unit stores the data;
when the power failure warning sent by the server is the emergency power failure warning with the highest priority, the user node receiving the emergency power failure warning executes the acquisition and storage of user node data, and when a detection module in the user node does not receive the emergency power failure warning, the detection module in the user node triggers the detection module to execute the data acquisition and store the data in a cache unit after detecting a power failure event; and when the data of the cache unit is close to a preset alarm value, sending an inquiry to the peripheral user nodes, when the user relay node responses, executing data transmission and forwarding, receiving the data by the user relay node, and sending the data to the server by the user relay node.
2. The system of claim 1, wherein when the detection module in the user node does not receive the emergency power-down warning, the detection module in the user node triggers the detection module to perform data acquisition and store the data in the cache unit after detecting the power-down event;
the method comprises the steps of detecting an alternating current power supply signal at the front end, judging whether a power failure event occurs or not, specifically, sampling input voltage of a power supply network, wherein the sampling of the input voltage is to execute periodic sampling, and when the sampled value meets a threshold value set by power failure expectation, triggering a backup power supply in a user node to start.
3. The system according to any one of claims 1-2, wherein the communication module of the user node further comprises that the user node receives configuration information sent by the server, and when the configuration information includes a user node configured as a user relay node and indicated as an active state, the user node set as the user relay node sends a broadcast message to the user nodes in the neighboring area through its own communication module, and receives data sent by the neighboring user nodes.
4. The system as claimed in claim 3, wherein the broadcast message includes information set as identification information of the user relay node and a size of the storage space.
5. The system of claim 4, wherein when the storage space of the buffer unit in the user node transmitting the power down event is insufficient, the broadcast message of the adjacent user relay node is received through the communication module, and the data transmission link is established.
6. The system as claimed in claim 5, wherein the transmission data of the neighboring user node includes user ID information and breakpoint information of the neighboring user node.
7. The system of claim 6, wherein when the emergency power down warning is determined, the user relay node immediately forwards the data of the user node with the power down event to the server after completely receiving and storing the data of the user node with the impending power down event, and when the server returns to parse right, the user relay node notifies the user node with the impending power down event to perform self-destruction of data.
8. The system according to claim 7, wherein when the device corresponding to the user node is identified by the scan code and the third party user performs the scan access, the communication module in the user node sends a prompt message to the user terminal device matched with the device of the user node.
9. The system as claimed in claim 8, wherein the user terminal device may be a mobile phone or a console with a large screen.
