Oil field Internet of Things system communication method

Abstract

The invention discloses an oil field Internet of things system communication method, which is compatible with the conventional oil field monitoring scheme and meanwhile has a wide expand space and a flexible protocol upgrading mode. The method comprises the steps that: 1) a sender packages a communication frame, wherein the communication frame consists of a packet header identification section, a packet length data section, a packet type section, a packet body section and a packet tail verification section, the packet body section comprises a plurality of sub packets, the data length and the data type of each sub packet of the packet body section are variable, and the packet type section comprises an oil field company code, a manufacturer code, a version number, a communication type code, and identification codes and packet serial numbers of the packet type section and a target device; and 2) a receiver receives the communication frame, analyzes data of the packet header identification section, the packet length data section, the packet type section, the packet body section and the packet tail verification section, and processes correspondingly. The method can meet the communication requirements of different levels, and thus the communication is relatively safe and reliable, and meanwhile, the variable data combination can be used for improving the flexibility and the adaptability of the method, and other corresponding industry applications can be expanded.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a communication method for an oilfield Internet of Things system. Background technique [0002] Communication protocol is an important and essential component in modern automation systems. As part of the system software, it cooperates with the hardware part to complete the transmission of system information and ensure the integrity, reliability and flexibility of information. [0003] Before the present invention, the protocols of the oilfield measurement and control systems made by various manufacturers were different, and data sharing could not be realized with each other, which often resulted in the need to install several sets of different application software in the same factory area and the same background. As a result, the collected data is scattered and the output format is not uniform, which increases the complexity of the user's use; at the same time, due to the incomp...

Problems solved by technology

As a result, the collected data is scattered and the output format is not uniform, which increases the complexity of the user's use; at the same time, due to the incompatibility of communication modes and protocols, different software must be equipped with specified hardware, which makes the user's terminal selection very difficult. Due to the shackles of the system, it is impossible to select the most cost-effective solution; each protocol is oriented to a limited measurement and control direction, and cannot be flexibly expanded to other related fields, so that a system is equipped with a protocol without continuity and inheritance, resulting in a lot of repetitive work
