Embodiment 1

[0036] Please refer to figure 1 , figure 2 and image 3 , the present invention provides a data transmission and communication method based on the Internet of Things, which is suitable for data transmission and communication of Internet of Things devices.

[0037] Such as image 3 As shown, the method may include the following steps:

[0038] S1: Preset a table of key-value pairs, which records the correspondence between custom field codes and communication data names.

[0039] The key-value pair table, also known as key-value table, is referred to as kv table in this embodiment. The kv table includes custom field codes and corresponding communication data names and descriptions. Among them, all field codes are not repeated, and all communication data that needs to be involved in device transmission are defined in the table; at the same time, it supports custom expansion of the content of the table according to the needs of device data transmission. Through the key-valu...

[0043] Table I

[0044] S2: The first Internet of Things device generates a communication message according to the key-value pair table, and sends it to the second Internet of Things device, the communication message includes a packet header and a data packet, and the packet header includes a message type, so The above data packet includes communication data and message sequence number.

[0045] Specifically, when the first Internet of Things device and the second Internet of Things device have communication transmission requirements, the first Internet of Things device will generate a specific communication message according to the definition in the kv table. In this embodiment, the generated communication message at least includes: a packet header and a data packet body (that is, a data packet). Wherein, the message category is recorded in the packet header; the data packet includes communication data and message serial number; and, the data format o...

Embodiment 2

[0058] This embodiment further expands on the basis of the first embodiment, and provides a data transmission method between IoT devices. The device refers to the Internet of Things device; the two ends of the communication docking can be between the client and the server, such as the lower computer device and the server, or the lower computer device and the upper computer device. The network used can be 2G, 3G, 4G, 5G, Wi-Fi, wired network, etc.

[0059] First, develop a data transfer protocol (HIOTP). Such as figure 2 As shown, the protocol does not depend on the specific physical communication method, and is further encapsulated on the UDP or TCP protocol. It is a data exchange protocol at the application layer. This protocol is especially suitable for information transmission of short text messages (such as voltage, current, etc.).

[0060] The data transfer protocol consists of two parts:

[0061] (1) Set the kv table in advance. For the kv table, refer to the descri...

Abstract

The invention provides a data transmission communication method and system based on the Internet of Things, and the method comprises the steps: presetting a key value pair table which records a corresponding relation between a custom field and a communication data name; enabling the first Internet-of-Things equipment to generate a communication message according to the key value pair table and send the communication message to the second Internet-of-Things equipment, wherein the communication message comprises a packet header and a data packet, the packet header comprises a message category, and the data packet comprises communication data and a message serial number; enabling the second Internet-of-Things equipment to analyze the communication message according to the key value pair table; enabling the second Internet-of-Things equipment to generate a response message according to the analysis result and the key value pair table, and send the response message to the first Internet-of-Things equipment, wherein the message category in the packet header of the response message is response, and the message serial number in the data packet is consistent with the message serial number in the received communication message; enabling the message serial numbers in the communication messages to increase progressively according to the generation sequence of the communication messages. According to the invention, the docking work of the Internet-of-Things equipment can be unified, the docking complexity and the docking cost are reduced, and the docking efficiency is improved.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a data transmission communication method and system based on the Internet of Things. Background technique [0002] With the advancement of the times and the development of science and technology, 2G, 3G, 4G, and 5G communications are more and more widely used in the Internet of Things. In the era of the Internet of Things, connected IoT devices emerge in endlessly, but there is no unified standard. Therefore, when the Internet of Things devices are connected, they have to adapt to various collection element data, which is complicated, heavy workload and low efficiency; [0003] Therefore, it is necessary to provide a new transmission docking method, which can reduce the complexity and cost of docking and improve the docking efficiency by unifying the docking work of IoT devices. Contents of the invention [0004] The technical problem to be solved by the present inventio...
