A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of radio-frequency identification signals, and indicative of proximity sensing at the module. A central computer accumulates the data produced or received and relayed by each module for analyzing inventory, pricing and customer responses to transmit through the adaptive network signals representative of information to be displayed at selectively-addresses modules in response to computer analyses of the data accumulated from modules forming an adaptive network.

The invention relates to an environment self-adaptation sensing wireless communication channel estimation and signal reconstruction method based on optimal recovery measurement induced by machine learning. The environment self-adaptation sensing wireless communication channel estimation and signal reconstruction method comprises steps that by using base station storage equipment, pilot frequency signals of time-space proximity, channel state information, and recovery measurement information are stored; a receiving end is used to receive the pilot frequency signals transmitted by a transmittingend, and by combining with the base station storage information, the machine learning method is adopted to realize the environment self-adaption sensing channel state and determine the optimal recovery measurement; the channel state information and the optimal recovery measurement are adopted to realize anti-interference, denoising transmission signal reconstruction. Based on the effective information stored on the communication base station and the machine learning principle, fast, effective learning, estimation, and elimination of influences of complicated noises on the wireless communication system can be realized, and therefore the robust estimation and the signal reconstruction of the wireless communication channels are realized in the same time or in shorter time by adopting the self-adaption way.

The present invention relates to an adaptive perception block chain hybrid consensus mechanism architecture and a method thereof. The architecture is a multi-chain system composed of a plurality of block chains, including a main chain and several remaining functional side chains. The purpose of the main chain is to record all the operational behaviors in the multi-chain system. The purpose of the functional side chains is to record the data resources corresponding to the needs. Different functional side chains record different data resources. There is a group of consensus mechanisms between the main chain and the functional side chain, called the consensus mechanism group, each type of consensus mechanism in the group is different, and can be added and deleted. When the main chain receives a certain functional operation, it will select the consensus mechanism corresponding to the function from the consensus mechanism group through the adaptive perception module in the multi-chain system to execute, and the selected consensus mechanism will generate blocks. At the same time, the data resources involved in the function are recorded on the corresponding function side chain. If there is a new demand, you only need to add the consensus mechanism corresponding to the demand to the consensus mechanism group, and add several functional side chains to bind with the consensus mechanism, so that when the main chain receives the functional operation corresponding to the demand, it can Correctly choose the corresponding consensus mechanism and functional side chain.
