Referring to fig. 1, a flow chart of a method for safely uploading and storing operation data of an internet of things terminal according to an embodiment of the present invention is shown. The method for safely uploading and storing the operation data of the Internet of things terminal comprises the following steps:
step S1, acquiring working state information of all gateway nodes in the Internet of things, and screening all gateway nodes in an available state based on the working state information; based on the position information of the Internet of things terminal in the Internet of things, constructing a communication channel between the Internet of things terminal and one of the gateway nodes in an available state;

Step S4, verifying the data packet received by the data storage terminal in the allowed connection period, and judging whether the data packet meets the preset data state condition; when the data packet meets the preset data state condition, the data packet is stored in the data storage terminal; and when the data packet does not meet the preset data state condition, discarding the data packet and returning a notification message to the Internet of things terminal.
From the above, it can be seen that the method for safely uploading and storing the operation data of the internet of things terminal constructs a communication channel between the internet of things terminal and one gateway node based on the working state of the gateway node in the internet of things and the position information of the internet of things terminal, and ensures the optimized data transmission between the internet of things terminal and the gateway node; the method comprises the steps that an internet of things terminal is subjected to data sampling detection processing to generate a data identification record, and when the internet of things terminal needs to upload data, a data packet to be uploaded is generated based on the data identification record, so that the data reliability of the data packet to be uploaded is ensured; determining an allowable connection time period between the Internet of things terminal and the data storage terminal based on a data receiving log of the data storage terminal, and distributing a specific time period for the Internet of things terminal to upload data to the data storage terminal so as to avoid interference or interruption of data uploading; and the received data packet is also subjected to verification processing, so that whether the data packet is directly stored or the internet of things terminal is informed to upload data again is determined, and the reliability and the safety of data uploading and storage of the internet of things terminal are ensured.
Preferably, in the step S1, working state information of all gateway nodes in the internet of things is obtained, and all gateway nodes in an available state are screened based on the working state information; based on the position information of the Internet of things terminal in the Internet of things, a communication channel between the Internet of things terminal and one of the gateway nodes in an available state is constructed, and the method comprises the following steps:
acquiring respective terminal connection load information of all gateway nodes in the Internet of things; the terminal connection load information comprises the number of the current connected internet of things terminals of each gateway node and the uplink data stream state information of each connected internet of things terminal; based on the terminal connection load information, determining average data flow and peak data flow received by each gateway node in a future preset time range; based on the average data flow and the peak data flow, judging whether the gateway node is in an overload data receiving state; if yes, determining that the gateway node is not in an available state; if not, determining that the gateway node is in an available state;
and determining the gateway node in the available state, which has the shortest communication link with the Internet of things terminal, based on the network address information of the Internet of things terminal and all the gateway nodes in the available state in the Internet of things, and constructing a communication channel between the Internet of things terminal and the gateway node in the available state.
In the technical scheme, a plurality of internet of things terminals and a data storage terminal are arranged in the internet of things; the internet of things terminal can be, but is not limited to, a sensing device, and corresponding detection data can be generated when the internet of things terminal senses and detects; the data storage terminal is used as data storage equipment of the Internet of things and is used for receiving detection data uploaded by all the Internet of things terminals, so that the detection data can be conveniently processed in a centralized mode. Meanwhile, the Internet of things also comprises a plurality of gateway nodes, and each gateway node can be used as a data transmission intermediate node between the Internet of things terminal and the data storage terminal, so that the detection data generated by the Internet of things terminal can be ensured to be accurately uploaded to the data storage terminal. When the Internet of things terminal is connected with the data storage terminal, the Internet of things terminal and one of the gateway nodes form a corresponding communication channel, and the gateway nodes and the data storage terminal form a corresponding communication channel, so that the oriented data uploading of the Internet of things terminal to the data storage terminal is realized. In the running process of the internet of things, the gateway nodes are correspondingly connected with the internet of things terminal, namely, not all gateway nodes are in an idle state which is not connected with the internet of things terminal, a certain upper limit of data receiving load exists on data uploaded by each gateway node to the internet of things terminal, when the gateway nodes are simultaneously connected with a plurality of internet of things terminals and/or data flow uploaded by the internet of things terminal to the gateway nodes is overlarge, the gateway nodes are possibly in an overload data receiving state, and if the gateway nodes are connected with another internet of things terminal at the moment, the data uploaded by the other internet of things terminal cannot be transferred to the data storage terminal in time and quickly by the gateway nodes. For this reason, the number of the internet of things terminals respectively connected with all gateway nodes in the internet of things and the uplink data flow state information of each connected internet of things terminal (namely, the data flow state information uploaded to the gateway node by the internet of things terminal currently connected with each gateway node) are obtained, so that the average data flow and the peak data flow received by each gateway node in a future preset time range are estimated and determined, and when the average data flow received by the gateway node from the internet of things terminal in the future preset time range is greater than or equal to a first preset data flow threshold value or the peak data flow is greater than or equal to a second preset data flow threshold value, the gateway node is determined to be in an overload data receiving state, namely, the gateway node is not in an available state; otherwise, it is determined that the gateway node is not in an overload data receiving state, i.e. the gateway node is in an available state. And determining the gateway node in the available state with the Internet of things terminal on the basis of the network address information of the Internet of things terminal and all the gateway nodes in the available state in the Internet of things, so as to construct a communication channel between the Internet of things terminal and the gateway node in the available state with the Internet of things terminal with the shortest communication link, improve the data transmission efficiency between the Internet of things terminal and the gateway node, and reduce the transmission delay of uploading data to the gateway node by the Internet of things terminal.
Preferably, in the step S2, a data sampling detection process is performed on the internet of things terminal, so as to generate a corresponding data identification record; generating live information based on the data of the Internet of things terminal, and judging whether the Internet of things terminal needs to perform data uploading operation or not; when the internet of things terminal needs to perform data uploading operation, generating a data packet to be uploaded based on the data identification record, including:
periodically sampling a data stream generated by the Internet of things terminal to obtain a plurality of data samples; detecting the data content of each data sample, and judging whether the data sample has data messy codes or not; generating a corresponding data identification record based on respective sampling time and data messy code existence conditions of the data sample;
acquiring real-time generated data quantity of the Internet of things terminal, and judging that the Internet of things terminal needs to perform data uploading operation if the real-time generated data quantity is larger than or equal to a preset data quantity threshold value; otherwise, judging that the Internet of things terminal does not need to carry out data uploading operation;
when the internet of things terminal needs to carry out data uploading operation, determining the respective sampling time of all data samples without data messy codes from the data identification record; and carrying out data picking processing on the data stream generated by the Internet of things terminal based on all sampling time determined from the data identification record, and converting the picked data into a data packet to be uploaded.
In the technical scheme, the Internet of things terminal can continuously generate corresponding detection data in the sensing detection process, when the Internet of things terminal has faults in the sensing detection process, the generated detection data can have the problems of data messy codes and the like, and the search data belong to error detection data and do not need to be uploaded to the data storage terminal.
