Pumping Well Data Acquisition Control System and Its Method Based on Wireless Network

Abstract

The invention relates to an oil pumping well data acquisition control system based on a wireless network. The oil pumping well data acquisition control system comprises a configuration computer, an industrial Ethernet, a WIA wireless gateway, well head control units, and a data acquiring terminal. The configuration computer is connected with the WIA wireless gateway through the industrial Ethernet. The well head control units are arranged on oil pumping well heads and wirelessly communicates with the data acquiring terminal and the WIA wireless gateway. An oil pumping well data acquisition control method comprises: meters transmit regularly-acquired oil pumping well data to a well head control unit in the same oil pumping well where the meters are located, wherein the well head control unit transmits the oil pumping well data to the WIA wireless gateway in real time; the configuration computer receives, through the industrial Ethernet, network state information and real-time data of each oil pumping unit transmitted from the WIA wireless gateway. The well head control units RTU are all provided with wireless routing functions and achieve data communication by means of a multi-hop network when a barrier blocks a wireless signal or the wireless signal is not very well, thereby guaranteeing data reliability.

Description

technical field [0001] The invention relates to a pumping well data acquisition control system and a method thereof, in particular to a pumping well data acquisition control system and a method based on a WIA-PA industrial wireless network. Background technique [0002] In recent years, data acquisition, process control, parameter optimization, and management decision-making based on oil and gas field production sites such as well sites, stations, and depots have become increasingly important. Data fusion and data application are playing an increasingly important role. The Internet of Things in oil and gas production is an inevitable trend in the development of oil and gas field information construction. [0003] The Internet of Things system for oil and gas production uses sensing, radio frequency, communication and other technologies to conduct comprehensive perception of production objects such as oil and gas wells, metering rooms, oil and gas stations, and related gather...

Problems solved by technology

For production data acquisition and control systems, there are two directions: wired and wireless. The wired acquisition and control system is inconvenient in terms of construction and maintenance. However, the current wireless systems are mostly designed based on the Zigbee system, and the success rate of wireless communication is low. Ensure the timeliness and accuracy of monitoring data throughout the day
