Local and remote control panel of soft starter of hydraulic pressure station

Abstract

The invention discloses a local and remote control panel of a soft starter of a hydraulic pressure station. The internal structure of the DSP control panel comprises a main control CPU, and the main control CPU is correspondingly connected with a power supply module PWR, a communication module CANopen, an input module IN, an output module OUT and a JTAG interface. The local and remote control panel achieves local / remote control and state display of the soft starter, supports the C and assembly mixing programming, and brings convenience to logic changes and function extension; the local and remote control panel is small and exquisite in size, simple in structure, easy to install and maintain, good in integration with a traditional hydraulic pressure station control part, long in service life, high in expansibility, simple in communication, good in protective performance and free of additional data acquisition cards, signals are isolated, the heat value of the local and remote control panel is low, the local and remote control panel can stably run in an explosion-proof box body, and a cooling system does not need to be additionally arranged.

Description

technical field [0001] The invention belongs to the technical field of electric control, and is used for realizing local and remote start-stop control and state display of a soft starter of a hydraulic station of an offshore oil drilling platform, and in particular relates to a local remote control board of a soft starter of a hydraulic station. Background technique [0002] The offshore oil drilling platform has a compact structure and a variety of equipment, among which the new automation equipment mainly adopts the electronically controlled hydraulic solution. To achieve precise control, there are strict requirements on the hydraulic source. Due to the different working content and working conditions of each equipment, it is necessary to equip a special hydraulic station for specific equipment. The operation mode of the equipment is generally remote centralized control, so there is a certain distance between the hydraulic station and the control room; thirdly, because the...
