Embodiment 1

[0027] Embodiment 1, the present invention is a grain supervision method based on blockchain and the Internet of Things, which is characterized in that it includes a supervisory platform, a gateway, a grain situation monitoring system, and a blockchain, and the supervisory platform is used to display information. The gateway is connected to the monitoring platform, the grain monitoring system is connected to the gateway, the block chain is connected to the gateway and the grain monitoring system, and various smart devices installed in the reservoir area are connected to the gateway. The equipment is used to collect monitoring information of various storage areas. The monitoring information includes information on the entry and exit of the grain depot, information on the illegal travel trajectory of vehicles, records of the opening and closing of the granary door, the quantity information of the grain in the warehouse, and the grain situation information of the granary, etc. Mon...

Embodiment 2

[0036] Embodiment 2. On the basis of Embodiment 1, both the gateway and the monitoring platform are registered in the block chain. At the same time, various smart devices need to be registered in the device authentication module of the gateway to become legal devices. The registration information includes the firmware ID and device type of each smart device. The gateway generates a smart device key based on the information, and then configures the smart device key to each corresponding smart device. The smart device key is used for each smart device. Identity authentication and data encryption between devices and gateway data transmission, only legitimate smart devices can report data to the gateway;

[0037] The registration of the gateway is to generate the gateway asymmetric key of the blockchain node in the gateway, and at the same time generate the gateway public key and register on the blockchain, generate the gateway blockchain certificate, and the blockchain authorizes ...

Embodiment 3

[0041] Embodiment 3, on the basis of Embodiment 2, the information of entering and leaving the warehouse includes the information of the grain households, which is filled in by the grain households, the quality inspection information of the grains is obtained by the quality inspection equipment, and the information of the weighbridge is obtained by the weighbridge equipment;

[0042] The illegal track of the vehicle uses RFID technology to record the reading and writing of the magnetic electronic tag through the reader device, and the gateway obtains the record from the reader device. Specifically, the vehicle entering the warehouse area is labeled with a magnetic electronic label by the labeling machine. Tag, if the vehicle passes the place that should not be passed, the data will be read by the reader and an alarm message will be sent, and the magnetic electronic tag record read by the reader will be reported to the gateway through the tcp protocol;

[0043] The quantity info...

Abstract

The invention relates to a grain supervision method based on a blockchain and Internet-of-things. The problems that in the prior art, grain storage data is difficult to collect, prone to tampering, incapable of tracing and the like in the collecting, storing and using process are effectively solved. According to the method, the system comprises a supervision platform, a gateway, a grain conditionmonitoring system and the blockchain, the gateway is connected with the supervision platform, the grain condition monitoring system is connected with the gateway, and the blockchain is connected withthe gateway and the grain condition monitoring system; wherein the gateway is provided with industrial acquisition and control interfaces of DI, DO, AI, RS485 and RS232, supports a 4G / NBIot communication mode, an Ethernet communication mode, a Wi-Fi communication mode, a Modbus TCP communication mode and a Modbus RTU communication mode, and reports information to a supervision platform through a TCP / UDP protocol; according to the method, a supervision platform user can check and analyze the detected and collected data, and timely discover the problems of the grain depot and the grains.

Description

technical field [0001] The invention relates to the field of blockchain technology and grain supervision technology, in particular to a grain supervision method based on blockchain and Internet of Things. Background technique [0002] Food is a major issue related to the national economy and people's livelihood, and food security is extremely critical. With the development of modern informatization, grain purchase, warehousing, storage, delivery, processing and other links are all changing to digitization, informatization, and intelligence. Up to now, modern information-based Internet of Things means have been more applied to the grain logistics industry to achieve the purpose of supervising grain quality deterioration, reducing grain loss, loss, and preventing grain pollution. Good quality, safe storage, and prevent major grain storage accidents. However, to achieve completely transparent traceability and unalterable key operating data in each link, it is still unable to ...
