Development of shale gas fracturing digital network control system based on programmable logic controller

摘要

This article proposed a novel fracture control system for shale gas fracturing truck used in the construction, blender, equipment vehicles connected by a PLC control network, each equipment is contacted with automatic remote control unit, the pressure to achieve through the network and treatment plant centralized control cracking operations, network control system uses ring industrial Ethernet connection. Each field blender, fracturing truck station data, parameters can be transmitted through the network in order to achieve data sharing and downloading function parameters pass each other. Meanwhile, An adaptive displacement control with hysteresis modeling for a fracturing truck is proposed in this paper, the ladder program has been used in the AB-PLC for displacement control, the result of experiment also show that the control system have improved the fracturing construction effect.
