China Szj-II Multi Parameter Drilling Instrumentation System

1.Application Areas:
SZJ-II Multi-parameter Drilling Instrumentation System is manufactured by JPIM for various drilling rigs, and is mainly used to measure and display variation of different engineering parameters during drilling process and assist drillers to monitor working status of drilling rig.
The system consists of sensors, Bus contacts, front-end driller's console (with PC104 built-in computer, touch-screen LCD display) and computer terminal in tool pusher's office.
2. Features:
1. Modularized structure and easy extension. Various parameters can be combined in accordance with requirement of customers;
2. Equipped with a built-in PC/104 industrial control computer, all the data can be acquired and processed in a reliable way.
3. Front-end monitor software can acquire and process 30 original parameters and 20 derivative parameters. Users can set up alarm threshold values of relevant parameters to realize acoustic and optical alarm.
4. Human-friendly design of monitor software can help drillers to switch between different display modes, such as analogue dial, digital display and curve display;
5. Wide TFT LCD touch screen, human-machine dialog operation and ideal visual effect.
6. Back-end monitoring software can perform real-time monitoring, acoustic and optical alarming and remote display; reports and curves of all the parameters can be displayed (in real time), saved and printed;
7. As all the composing parts of system are connected through CAN bus, it is easy to conduct field installation, adjustment and maintenance;
8. The system enjoys a wide range of working voltage, excellent stability, strong anti-jamming capacity and long-term trouble-free service.
