The monitoring system comprises an Internet of Things node and a plurality ofradio frequency energy modules, wherein the Internet of Things node comprises an acquisition node used for acquiring environmental data, a relay node and an aggregation node; the acquisition node isconnected with the relay node and transmits node data to the relay node according to the data transmission probability of the acquisition node, and the relay node is connected with the aggregation node and transmits node data to the aggregation node according to the data transmission probability of the relay node; each radio frequency energy module is used for collecting energy and sending corresponding energy to surrounding collection nodes and relay nodes through radio frequency signals generated through radio frequency beam forming based on the sending power of the energy. According to theinvention, the node data can be fairly collected and the charging amount can be reasonably distributed based on the local information of the nodes, the node energy utilization efficiency can be improved, and the method can be applied to the rechargeable Internet of Things with a large network scale, a wide coverage range and a poor deployment environment.

Description

technical field [0001] The invention relates to the technical field of communication protection, in particular to a monitoring system and a distributed protocol for large-scale rechargeable Internet of Things. Background technique [0002] The IoT monitoring system requires the ability to receive monitoring data from each IoT node in a timely manner, which often involves node power issues. Due to the small size of IoT nodes and limited power capacity, regular replacement of node batteries is a mainstream solution in the industry. However, future communication equipment has the characteristics of high-speed transmission, massive connections, and huge energy consumption. It is impractical to replace node batteries on a large scale and frequently. Therefore, charging nodes has become an important technical means to solve this problem. [0003] At present, the way of using solar energy harvesting technology to charge nodes is widely used, but the energy of this technology is u...

Problems solved by technology

[0004] However, the existing rechargeable IoT monitoring system based on radio frequency beamforming technology has the following problems: In terms of charging strategy, the current technology ignores the impact of nonlinear radio frequency energy conversion process and time-varying channel on energy and data transmission, It reduces the accuracy of charging decisions and affects the charging effect of nodes; in terms of data collection, most current technologies use single-hop networks, which lack the combination of routing selection and link scheduling with multi-hop networks, and cannot improve node energy and reduce node energy. In terms of network scale, current technologies mostly consider charging based on a single radio frequency energy, and the radio frequency energy needs to be connected to the main power grid, which limits the network scale, coverage and deployment environment of the Internet of Things
