Low power consumption transmission system and method for oil field data collection

Abstract

The invention discloses a low power consumption transmission system and method for oil field data collection. The method comprises the following steps: initializing a Lora terminal and a Lora concentrator; sending, by the Lora terminal, a network access request to the Lora concentrator; judging, by the Lora concentrator, whether the Lora terminal is a new node or an old node; if the Lora terminalis the new node, performing network access authentication on the Lora terminal, registering the Lora terminal in a network route established by the Lora concentrator, and performing networking after the network access authentication is successful; if the Lora terminal is the old node, registering the Lora terminal in the network route established by the Lora concentrator, and performing networking; performing, by the Lora concentrator, time synchronization, and distributing time slices through the Lora terminal, and then entering a sleep state; and obtaining, by the Lora terminal, the time slices, entering the sleep state and periodically waking up to report uplink data. According to the low power consumption transmission system and method disclosed by the invention, the collection, transmission and processing of oil field data are achieved by a wireless sensor network of a component of the Lora concentrator and the Lora terminal, the low power consumption transmission system and method are suitable for the application demands of numerous oil field points and large distance, the node power consumption is reduced, and the networking, deployment and maintenance costs are reduced.

Description

technical field [0001] The invention relates to the technical field of oilfield data acquisition, in particular to a low-power transmission system and method for oilfield data acquisition. Background technique [0002] The Internet of Things is a combination of sensor networks and the Internet, in which the sensor network is used for data collection, human-computer interaction and short-distance data transmission, and the Internet is used for long-distance data transmission and data services. The Internet of Things can be applied to different industries, and each industry has its own unique data content. There is no unified standard for the self-contained Internet of Things application systems in different industries, forming various information islands, and it is impossible to carry out efficient data sharing and data exchange. Data processing wastes a lot of server and energy resources. [0003] The existing oilfield automation data acquisition and transmission scheme is ...
