Problems solved by technology
Once the water conservancy early warning is delayed or illegal personnel maliciously tamper with the early warning data of each station to cause false early warning, it will threaten the safety of water conservancy public infrastructure and bring unnecessary personal and property losses to the government and the public.
[0003] The technical problem to be solved by the present invention is that the existing water conservancy early warning system lacks anti-replay and anti-tampering mechanisms, and the time delay of broadcast early warning is relatively long

The invention provides an intelligent water conservancy wireless early warning system based on a ZigBee technology, which comprises a three-layer topological tree network structure consisting of a coordinator, a plurality of routers and a plurality of water conservancy early warning terminals, and further comprises a management center, the coordinator is located at the topmost layer of the network structure, a CC2538 chip is adopted in the hardware design of the coordinator, and the coordinator is responsible for ECC encryption and decryption of early warning data frames, receiving early warning information uploaded by a water conservancy early warning terminal, broadcasting the early warning information in the whole network and regularly updating an ECC encryption and decryption key in the whole network; and the router is located at the middle level of the network, and is used for data forwarding, CC2591-based wireless transmitting power amplification and ECC-based data encryption and decryption functions, and supporting key data table maintenance of ECC encryption and decryption public and private key pairs of the water conservancy early warning nodes. Based on hardware CC2538 chips, CC2591 chips, a secret key matching mechanism, a frame number mechanism and a Zstack protocol stack design, the intelligent water conservancy wireless early warning system capable of meeting the requirements for network data replay prevention, data tampering prevention and low time delay is achieved.
Description
technical field [0001] The invention belongs to the technical field of ecological hydrology, and in particular relates to an intelligent water conservancy wireless early warning system based on ZigBee technology. Background technique [0002] Water conservancy early warning is the top priority of flood control forecast and early warning and disaster reduction work. In recent years, the frequency of water conservancy natural disasters such as urban waterlogging, reservoir bursting, and spring icing has increased year by year. The existing water conservancy early warning system still relies heavily on the aggregation of data from various monitoring stations to the monitoring center for early warning decision-making. Data security protection mechanisms such as storage and anti-tampering. Once the early warning of water conservancy is delayed or illegal personnel maliciously tamper with the early warning data of each station to cause false early warning, it will threaten the s...
