A data acquisition and control system for a safety valve test bench with high pressure and large flow rate, was developed based on the host-slave architecture, which takes an Industrial Personal Computer (IPC) as host computer and a Programmable Automatic Controller (PAC) as salve computer. The hardware architecture and software design of this system were introduced in detail. This system was verified by the experiment, and the results indicate that it can fulfill the requirement of data acquisition and control with high speed and long distance. This study can provide reference for many automation control fields.

This paper introduces a data transmission circuit used to transmit signals over thousands of meters in borehole; meanwhile, a control system that is equipped with the circuit is also presented here. This set of equipment has many advantages over previous systems-smaller size, less cost, longer communication distance and friendlier user interface. The design of hardware in the system consists of LVDS transceiver circuit, USB port circuit based on high speed MCU C8051F321, automatic power-on circuit based on relay TQ201 and acquisition circuit based on 24-bit analog-to-digital converter LTC2492. The software is based on both C language and VC++6.0. Finally, it accomplishes a kind of data transmission circuit and control system in borehole which delivers the data from thousands of meters away.

The structure and characteristics of test signals of the experimental device for cutter head in shield machine are analyzed. Based upon this analysis, Profibus-based control system is designed. With the use of a distributed I / O station on-site analog signal, the problems of anti-interference for long-distance transmission of signals are resolved, and high-speed transmission for sensor signals and control signals are realized.
