the box sealing state information comprises bin sealing position data and grain quantity data, and the grain quantity is acquired by a weighing sensor;
the multifunctional gateway of the internet of things receives original sealing position data and original quantity data sent by sensor equipment for container sealing inspection through a switchable RS232/485 interface, filters noise of signals and transmits the filtered signals to an embedded industrial control mainboard; after the industrial control main board receives the data, according to the configuration condition of the webservice service program running on the main board, original sealing position data and original quantity data sent by the sensor equipment for container sealing inspection are converted into sealing position data and grain quantity data in a preset protocol format and sent to the cloud platform.
9. The container grain box sealing inspection code-assigning block chain data collection system of claim 6,
the cloud platform generates a box sealing inspection state tracing code of each bin according to a box sealing inspection identification code compiling rule and according to box sealing state information and state information of intelligent lock equipment, and the method comprises the following steps:
generating fields of all box sealing inspection state tracing codes which are in accordance with the box sealing inspection identification code compiling rules according to the box sealing state information and the state information of the intelligent lock equipment by taking the container as a unit;
the field of the box sealing inspection state tracing code comprises: a sealing inspection state identification code, a container number, a lead sealing number, container sealing time, cargo space ex-warehouse time, cargo space in-warehouse time, grain properties, a service number, quantity, a variety code, a production place code, a production year and a grade code;
wherein, the container sealing inspection state identification code is a unique identifier of the container grain in the container sealing process;
the lead seal number is the lead seal number of the seal box after the container is filled.
10. The container sealing inspection assigning code block chain data acquisition system of claim 6, further comprising:
an intelligent lock;
after the box sealing inspection is finished, an intelligent lock is additionally arranged for each container or each bin;
the read-write module of the intelligent lock periodically detects whether an access card approaches;
when the forced unlocking is judged, starting an alarm program;
and the NB-IoT module of the intelligent lock sends the state information of the intelligent lock equipment and the timestamp information of the intelligent lock equipment to the cloud platform.
