Pneumatic control fault diagnosis system of drilling machine driller room

Abstract

The invention relates to a pneumatic control fault diagnosis system of a drilling machine driller room. The system is composed of a data acquisition unit, a data processing and diagnostic unit, and a data display unit. The data acquisition unit consists of control assemblies like a gas control valve, an electronic control valve, and pressure sensors; and the data processing and diagnostic unit includes an analog input module and a programmable logic device. The pressure sensors are installed at input terminals and output terminals of the gas control valve and the electronic control valve. The data processing and diagnostic unit sends an electric signal provided by the data acquisition unit to the analog input module; and the programmable logic device carries out a logic analysis on the collected data and makes a judgment on the system equipment working state and the fault position, thereby providing data for the fault diagnosis. According to the invention, the pneumatic control fault diagnosis system can detect and display a working state of gas circuit control of a driller room timely; and when a fault occurs, a fault type and a fault point can be determined and reported timely, so that the operation and maintenance staff can solve the fault problem timely and efficiently.

Description

technical field [0001] The invention relates to oil drilling equipment, in particular to an air control fault diagnosis system for the driller's room of the drilling rig. Background technique [0002] As the drilling rig control center, the driller's control room is the core component of the oil drilling rig. The driller directs the drilling operations of the entire oil well site in the driller's control room. With the advancement of technology, the structure of the equipment in the driller's control room is becoming more and more complex, the functions are becoming more and more perfect, and the degree of automation is getting higher and higher. In the process of operation, due to many unavoidable factors, various failures of equipment will occur, which will affect its set functions and even cause serious catastrophic accidents. Even accidents in routine production can cause huge economic losses due to abnormal operation of the production process or damage to machinery an...
