In an optional embodiment of the present invention, the information processing method of the internet of things device may further include:
and step 14, converting the JSON format data of the cloud platform server into binary data, and sending the binary data to the Internet of things equipment.
The following describes a specific implementation of the above method with reference to fig. 2, fig. 3, fig. 4, and fig. 5:
as shown in fig. 2, S1: the internet of things cloud platform defines a resource model of a product, and the data format of the resource model after definition comprises the name of the product (the name of equipment), the id number of the product (the id number of the equipment), the name of a contained function point, the type value of the function point and the like;
s2: a monitoring unit of the cloud platform receives write-in information of the Internet of things equipment, wherein the write-in information comprises basic equipment information and function points; the monitoring unit can be arranged in the resource model processing device or can be an independent module of the cloud platform;
s3: the data conversion center processes the written information, if the format of the written information accords with the data format of the resource model, the written information is forwarded to the equipment or the platform side, and if the format of the written information does not accord with the data format of the resource model, error information is returned; the data conversion center can be arranged in the resource model processing device, and is a part of a processing module in the resource model processing device or is a processing module; the data engine identifies and distributes the written information;
s4: the equipment side receives the information and issues a relevant instruction to the equipment; the platform side receives the information and feeds the information back to the user;
in the embodiment, all the data transferred between the internet of things equipment and the internet of things cloud platform need to be subjected to standardized format conversion through the resource model;
the data format of the resource model is divided into binary data and JSON data, wherein the binary data is mainly on the device side, and the JSON data is mainly on the platform side;
the function points comprise three types of basic function points (common function points and fault function points), combined function points and fixed function points;
wherein the failed function point is a function point having some determined failure of the device at a fixed location of the data; in the prior processing of the fault function point, each time a platform issues a command for inquiring fault to the equipment, the information of the fault point is needed, and the return is the reason of the fault.
The advantage of this is that under the condition of large data volume, the flow of the platform can be compressed, and the efficiency of platform processing is improved.
Furthermore, the combined function point is a function point which combines a plurality of independent function points for reporting or issuing, the plurality of function points are combined into one function point according to the nesting principle, the equipment issues the combined function point to support one-time issuing, and compared with the prior art that a plurality of function points are issued in sequence, the efficiency is greatly improved;
the combined function point realizes the combined uploading and combined issuing of a plurality of pieces of data, the combined uploading and combined issuing means that a plurality of pieces of function point data which need to be uploaded or issued are combined into one piece of data after being subjected to standardized conversion according to a specified protocol specification, and the combined data is encapsulated to carry basic equipment information which is used for specifying the flow direction of the data or specifying the source of the data; the data can be converted into a format and stably run according to the protocol specification in the circulation process.
For example, when a plurality of function points need to be reported, the number of reports increases the concurrency, which may cause channel blocking, message delay, and increase the server pressure. The combined reporting reduces the reporting times, and the reporting of all the function points can be completed once, so that the risk is avoided; for example, when three function points of a device report data to a platform, three pieces of data are often required to be reported: 1) data of the bootean type; 2) string type data; 3) number type data.
By adopting the mapping method in the embodiment of the invention, the three pieces of data can be combined into one piece for reporting. Specifically, three pieces of data may be merged into one flow for reporting as shown in fig. 3, the three pieces of functional point data are subjected to standardized conversion and merged into one piece of data, the data are packaged to carry basic information of the device, the cloud platform receives the data and identifies whether the data conform to a resource model data format, and if so, the written information is identified and distributed.
Furthermore, the fixed reporting function point is configured by the user according to the requirement, and can report real-time data of the device through the fixed reporting function point, thereby enhancing the real-time performance, reducing the data flow and improving the system efficiency; at present, equipment of each Internet of things platform does not support the attribute of the function;
