Oil well load monitoring system

Abstract

An oil well load monitoring system belongs to the field of monitoring equipment. The oil well load monitoring system is characterized by comprising terminal nodes, a routing node, a coordinator node, a PC host and a terminal server; the terminal nodes and the routing node are connected through a wireless signal, the routing node and the coordinator node are connected, a coordinator and the PC host are connected, the PC host and the terminal server are connected, and the terminal nodes are disposed at various oil wells; and each terminal node comprises a sensor module, a processor module, a wireless transmission module, a power supply module, a digital-to-analog conversion circuit and an indication lamp, wherein the sensor module, the wireless transmission module, the power supply module, the digital-to-analog conversion circuit and the indication lamp are connected with the processor module. A controllable signal gain adjustment function is achieved, and the oil well load monitoring system has the advantages of flexible communication, fast networking, low power consumption, less investment cost and the like. On-line monitoring for a well head oil pressure is achieved, a traditional passive mode relying on experiences and manual inspection tour is converted into intelligent management, and the oil well load monitoring system has great popularization value.

Description

technical field [0001] The invention belongs to the field of monitoring equipment, in particular to an oil well load monitoring system. Background technique [0002] During the oil extraction process of the pumping unit, the sucker rod has to bear the gravity of the liquid column, the inertial load, the frictional force, etc. along the axial direction of tensile or tension-compression alternating loads. If these loads exceed the bearing range of the sucker rod, the sucker rod It is easy to break off and fail, which will greatly increase the production difficulty of the oil well, and then affect the production schedule. The existing monitoring system needs to collect signals through a large number of wirings, which is difficult to implement in places with poor ground environment, and it is not convenient for network control. When the scale of oil wells is expanded or reduced, the monitoring system cannot be timely Adjustment. Contents of the invention [0003] The present...
