Considering the requirement of the multi-parameter-combined environment testing device, a kind of multi-parameter measure and control system based on wireless communication technology was studied in this paper. First, the overall structure of the multi-parameter measure and control system based on wireless communication in combined environment device was put forward, which was made up of six control subsystems: a host computer, the centrifuge and dynamic balance system, the vibration and rectification system, the temperature system, the air pressure system and the sound pressure system. Then, the communication protocol and hardware structure of the multi-computer communication system based on wireless transmission were mainly studied. And software design technology of multi-parameter measure and control system was studied in succession. Finally, the five-parameter-combined environment testing was carried out. The experimental results show that the measure and control tasks of the combined environment testing can be well finished by the multi-parameter measure and control system.

In deep wells and ultra-deep wells the complex geological conditions often result in serious casing wear. In order to obtain the wear efficiency which is used to compute the wear depth of downhole casing, the ring block drillpipe casing wear tester is developed. The measure and control system which include the measure circuits of contact forces between casing and drillpipe samples, the measure circuits of the friction forces are main component of wear tester. It is very important to design the measure and control system of tester. The paper also develops the calibration method of the loads sensors used to measure the contact and friction force. The wear tester can accurately measure the wear efficiency and the friction coefficient needed by casing wear prediction.

Welding quality control is critical for welding manufacturing. However, the factors that affect welding quality exist in the whole welding process. Whole process welding quality control is a technology control process that can control the welding quality from choice of the welding material, stability of the welding process and quality assurance after welding. In this paper, a quality measure and control system is developed. The system is consisted of three modules: Technology property evaluation and welding material choice module is based on Analysator Hannover. This module can evaluate three type of welding material: electrode, solid welding wire and flux-cored wire. The welding process stability evaluation module can collect electrical and light spectral signal for disturbance factors diagnosis during the welding. The metallurgical structure and property forecasting module call the CCT diagram data base for predicting he metallurgical structure and mechanical property of the weld affected zone and weld metal. For stainless steel, a predicting method based on Schaeffer is also provided in this module.
