Drilling machine electric control system power point temperature rise stepped grading automatic early warning method

Abstract

The invention discloses a drilling machine electric control system power point temperature rise stepped grading automatic early warning method. The drilling machine electric control system power point temperature rise stepped grading automatic early warning method comprises the following steps that (1), it is determined that a drilling machine system is ready; (2), the drilling machine system is started to operate; (3), temperature rise detection is started; (4), based on the normal temperature rise, the accumulated temperature rise and the temperature rise rate is calculated through the detection of the operation temperature rise; (5), the obtained accumulated temperature rise is compared with a set temperature rise step; (6), if the obtained accumulated temperature rise enters a set temperature rise step; (7), whether the temperature rise rate is greater than a corresponding set value or not is compared; (8), if the temperature rise rate is greater than the corresponding set value, the step (9) is executed; (9), the obtained accumulated temperature rise enters a set temperature rise step; and (10), early warning is completed. According to the drilling machine electric control system power point temperature rise stepped grading automatic early warning method, the problems of simple design, low automation level and low precision of a fire early warning device of an existing petroleum drilling machine electric control system are solved.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a method for automatic early warning of temperature rise at a power point of a drilling rig electric control system in steps and grades. Background technique [0002] Oil drilling is one of the core projects of the oil industry, and its technical equipment level reflects the comprehensive development level of the oil industry to a certain extent. The degree of automation and intelligence of the electronic control system of oil drilling rigs is on the rise. Electricity, as the production and life of modern oilfields, not only brings high efficiency and convenience to human beings, but also the harm caused by fires caused by improper use of electric energy is very alarming. Therefore, as the electronic control room, which is an important part of the oil drilling rig, the importance of early warning of heating failure or fire symptoms (that is, the temperature rise of ke...
