Automatic control system of fracturing truck

Abstract

The invention discloses an automatic control system of a fracturing truck. The automatic control system comprises a host computer, a programmable logic controller, a data acquisition system and a control actuator. The data acquisition system includes a pressure collector and a discharge collector; the control actuator comprises a frequency converter and an actuator motor; the output of the pressure collector and the output of the discharge collector are connected with a data processing unit; the data processing unit is connected with the programmable logic controller; the output of the programmable logic controller is connected with the frequency converter; and the programmable logic controller is connected to the host computer through a line. The beneficial effects of the invention are that: the local monitoring and the remote monitoring are realized; the operator can timely and accurately monitor the real-time working condition data and adjust the running state; the operator at the remote control computer can simultaneously monitor multiple fracturing trucks; the difficulty of monitoring is reduced and the monitoring efficiency is enhanced; the parameter can be set, so that the fracturing pump can operate in the automatic and stable manner; and the advantages of the convenient control, centralized monitoring data, and far control distance are realized.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling equipment, in particular to an automatic control system for a fracturing vehicle. Background technique [0002] At present, the fracturing pumps of the existing fracturing trucks have the problems of untimely and incomplete collection of production data and imperfect automatic control functions. The transmission distance of the existing control system is short, the transmission data is small, and the on-site working conditions cannot be observed and monitored in time. Although each fracturing vehicle has a corresponding status and fault indicator instrument, it can only be read by front-line operators. Data monitoring , Collection workload is heavy. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide an automatic control system for fracturing vehicles that can monitor working condition data in time and ...
