Traceability anti-channel conflict system and method based on Internet of Things and block chain

Abstract

The invention discloses a traceability anti-channel conflict system and method based on the Internet of Things and a block chain. The system comprises an SAAS service module, a block chain alliance chain platform and a traceability terminal device. The traceability terminal device is internally provided with a GPS antenna, a GSM antenna, a GSM module, a GPS positioning module, an MCU module, a charging management module, a battery module, an activation trigger switch, an RFID tag, an NFC tag and a two-dimensional code identification module. The GPS antenna and the GMS antenna are respectivelyconnected with the GSM module and the GPS positioning module; the MCU module is connected with the GSM module, the GPS positioning module, the charging management module, the activation trigger switch, the RFID tag, the NFC tag and the two-dimensional code identification module, and the charging management module is connected with the battery module. According to the invention, through the uniqueidentification of the traceability device for the product, one object and one code can be truly realized, one-to-one correspondence between physical world commodities and the system is realized, collection of track data of the commodities from delivery to use is realized, and channel conflict sales is prevented.

Description

technical field [0001] The invention belongs to the field of food safety supervision, and in particular relates to a system and method for traceability and anti-false goods based on the Internet of Things and blockchain. Background technique [0002] Food traceability has gone through years of development. Based on RFID and QR codes, a variety of traceability solutions have been formed to break through the upstream and downstream information barriers. However, there are still three problems in general: First, from the perspective of the overall structure, the traditional traceability The schemes are all centralized storage models, which have disadvantages such as easy data tampering and opaque information; secondly, from the perspective of data carriers, purely using RFID solutions, consumers need to use special equipment for traceability inquiries, which is inconvenient. The QR code solution is convenient for consumers to inquire, but it is very easy to be forged, that is, ...

[0002] Food traceability has gone through years of development. Based on RFID and QR codes, a variety of traceability solutions have been formed to break through the upstream and downstream information barriers. However, there are still three problems in general: First, from the perspective of the overall structure, the traditional traceability The schemes are all centralized storage models, which have disadvantages such as easy data tampering and opaque information; second, from the perspective of data carriers, purely using RFID solutions, consumers need to use special equipment for traceability inquiries, which is inconvenient

The QR code solution is convenient for consumers to inquire, but it is very easy to be forged, that is, it is difficult to correspond between physical goods and digital assets; the third is that the existing traceability solutions cannot solve the problem of goods fleeing
