Abstract
To solve the problems of centralization, tampering, incomplete storage, and privacy of fire fighting equipment traceability system, this paper proposes a fire fighting equipment information traceability system based on blockchain. The system is developed on the Fabric blockchain platform of Hyperledger. The system environment is equipped with three organizations: manufacturer, dealer, and consumers, and the query request is initiated with the traceability function of fire fighting equipment in the chaincode. Finally, through the certificate authentication user account can realize the fire fighting equipment information inquiry, and the query response time average value is 19.5 ms. The characteristics of blockchain are difficult to tamper with, timestamp and transaction traceability, which can be well applied to the traceability system of fire fighting equipment, which makes the traceability function of the system more perfect, and consumers can get all traceability information, including production information, logistics information and usage information of fire fighting equipment.
Highlights
In today's fire protection field, due to the opacity of the maintenance of fire fighting equipment, it is difficult to trace the responsibility according to the state of fire fighting equipment after the accident [1]
Consumers use organized certified user accounts to log on to blockchain fire fighting equipment anticounterfeiting traceability platform, input fire fighting equipment traceability code, You can jump to the fire equipment traceability information display interface, fire equipment from production to use each stage of traceability information
Is an example of a "carbon dioxide fire extinguisher" for fire fighting equipment, Assuming the carbon dioxide fire extinguisher's traceability code is 0000001, As shown in Figure 7, the query request equipment _id=0000001 is initiated in the browser, You can get traceability information, The data are shown in Figure 7, It can be seen that the traceability code of fire fighting equipment in the query result is consistent with the input traceability code of fire fighting equipment
Summary
In today's fire protection field, due to the opacity of the maintenance of fire fighting equipment, it is difficult to trace the responsibility according to the state of fire fighting equipment after the accident [1]. To solve the problem of traceability of fire fighting equipment, the industry has adopted the method of deploying a supervision system. This kind of information record for fire fighting equipment adopts C/S, B/S mixed architecture design, and the deployer of the system is the central fire protection product supervision organization [2]. Blockchain technology is combined with modern fire control, and the distributed decentralized system scheme is adopted, which fundamentally ensures the data can not be tampered with and avoids the malicious tampering of fire equipment information by third parties to maintain their interests. Can effectively solve fire safety system information sharing, data security, and other issues
