Design And Implementation Of Master Control Station In The Deepsea Hydraulic Pressure Flying Lead Test System

With the scarcity of land resources and the growing demand of energy, people gradually focus on rich products in the sea. For there’re extremely rich resources in the ocean, all the world rush to start the exploration and development of marine resources. Unlike land petroleum exploitation, offshore oil exploitation promote a combined system with electric control and hydraulic control. This system is composed of underwater produce facilities and ground control stations. The underwater facilities are connected by hydraulic pipeline and electric hydraulic head. The ground stations are responsible for providing UI interface and logic control. This paper design a set of master control station for the deep-sea electro-hydraulic head testing system. It is based on a series of technologies such as power line carrier transmission, data acquisition sensors, error rate calibration, long-distance real-time transmission control and UI interface. This station can provide power supply, logic control and data acquisition for the testing system.In this paper, a master station design scheme is adopted which integrates proximal power cabinet, distal power cabinet and PC monitoring interface. The control station can collect and transmit voltage value, current value and hydraulic pressure. Also it can control 500 VAC and the state of electromagnetic valve(on and off). Additionally, it can make a real-time error rate test and design monitoring system on PC.The main work in this paper is: peripheral module hardware design of master station, hardware and software design of proximal power cabinet and distal power cabinet, PC monitoring software design and system debugging.As for hardware of master station, there is uninterruptible power supply(UPS), Vicor power module V300C24E150BG3, KQ130485 F, pressure, voltage and current sensors and two kinds of transformer which transform AC220 V to AC500 V and AC500 V to AC220 V.As for hardware of proximal power cabinet, STM32 is as central processor and the software system is responsible for communicating with PC monitoring software and distal power cabinet.The hardware of distal power cabinet need two STM32 as central processor. The reason for this is that there are more remote mounted sensors which lead to more AD transformer. The software is designed to complete data collection from sensors, send those data according to control command and control relay action.And for the last part—system debugging, it first makes a separate hardware and software debugging for proximal electric cabinet system, distal power cabinet system and PC monitoring software. Then master control system testing is made in the laboratory environment. It should complete the sensor data transceiver, relay control and error rate test. Finally, it completes the alignment of the entire deep-sea electro-hydraulic head testing system.At the end of the paper, the problems happened during the project and solutions are summarized and the deficiencies of this system are also analyzed. Also the future trend and characteristics of the deep-sea test system design and implementation is prospected and finally some suggestions on how to further improve this topic are given.
