The invention relates to a coal mine safety information mobile verification terminal based on a PBFT technology. The terminal is provided with a controller, a receiving and sending module, a positioning module, a display module, a random number module and a signature module. After the receiving and sending module receives safety information, the positioning module immediately generates position information of a verifier at the moment, the received safety information and the position information generated by the positioning module are displayed through the display module, the verifier confirmsthe safety and position information and signs after the information meets the safety specification, and otherwise signature rejection is conducted through the signature module. And at the moment, thecontroller generates a random number through the random number module, packages the random number with the received security information and signature information, determines the next information verification terminal according to the generated random number, and sends the packaged information. The terminal adopts a PBFT consensus algorithm at the bottom layer of a block chain to improve the accuracy and reliability in the coal mine safety information transmission process, meanwhile, a random number sending mode also reduces the possibility of concealing the safety information, and due to theportability and low cost of the terminal, the large-scale underground use of the terminal becomes possible.
Description
technical field [0001] The invention relates to a coal mine safety information mobile verification terminal based on the PBFT consensus algorithm at the bottom of the block chain, and is an information verification terminal based on information verification signatures and random numbers to determine transmission. [0002] technical background [0003] Coal mine underground safety information includes massive information data such as equipment operating parameters, environmental parameters, and underground personnel information. At present, the collection, recording and uploading of safety information are mainly done through sensors and relevant underground personnel. However, due to the negligence of the detection personnel and the lack of verification during the information uploading process, errors may occur during the information collection process, and relevant personnel will conceal them, etc. A series of problems have laid hidden dangers for the occurrence of safety acc...
