firstly, issuing demand information through a material acquisition party, carrying out hash operation to obtain a hash value D1, executing intelligent contract deployment uplink, recording deployment contract addresses, generating material demand codes, wherein the obtained hash value can be used for obtaining detailed material demand information on an IPFS, automatically matching adjacent intermediate mechanisms by calling a database according to the demand information, transmitting the demand information to the mechanisms, and obtaining emergency materials in a mode of issuing recruitment information and/or initiating purchasing after verifying that the materials are identified;
when emergency materials are acquired through a recruitment mode: after a donor browses the issued related demand information and confirms donation, carrying out hash operation on the donation information of D1 and the donor to obtain a hash value, executing contracts, deploying a link, recording a deployment contract address D2, generating a recruitment information code, and automatically executing contracts to generate a donation certificate after being checked and accepted by an intermediate mechanism logistics;
when emergency materials are obtained through a purchasing mode: performing hash operation according to inventory feedback and D1 to generate a hash value, executing an intelligent contract, deploying a uplink, recording a deployment contract address D3, and generating a purchase information code;
the setting unit is used for setting an anti-counterfeiting identification code corresponding to the target emergency material after the target emergency material passes through the detection unit;
the generation unit is used for generating a logistics route reaching the emergency area according to the starting site of the target emergency material and storing the logistics route in the blockchain;
a confirmation unit configured to execute conveyance based on the originating station after confirming a traffic state of each logistics node associated with the logistics route;
the tracking unit is used for tracking the passing state of the logistics node in real time or automatically updating the logistics route according to traffic road conditions and/or weather conditions.
10. A blockchain-based emergency material management device comprising a processor, a memory, and a computer program stored in the memory, the computer program being executable by the processor to implement a blockchain-based emergency material management method as in any of claims 1 to 8.
