The Study On Environment Experament Parameter Test Technique Based On Computer Network

With the improving of test technique, the multiple environment experiment parameter test technique has permeated in environment experiment. It is request that all test systems for vary parameters measurement could exchange data, communicate and be integrated. It is implemented that the integrated system can deal with vary parameters together, display by multiple real time and data confusion.the development of computer network technique introduces the new method and approach of environment experiment parameters multiple test.First the characteristic and request of environment experiment parameters test is introduced in this thesis. The thesis analyzes and compares two popular network modes behavioral between client/server and brower/server based on abave discuss.the new system structure of network test system that integrates advantages both modes and suit for environment experiment parameters test specification is designed in the thesis.Then the specific implementing scheme is determined according to present status and development of environment experiment parameters test technique.this thesis presents concrete structure and composition of network environment experiment parameters test system and describes sub-system parameter test principle, hardware construction and software programming in detail. They include temperature test system, stress and strain test system and displacement test system.In the procedure of software programming the multithreading programming technique, Winsock technique, Web database technique, ASP technique and AxtiveX technique have been aopted. The system can perform parallel multitask of data acquisition, network communication and data broadcast in test server. The operational principle and implementation of key technique bave been discussed in detail.Fanilly the functions of the designed system to improve are discussed in thesis.
