Paper Abstract

This paper presents an electropneumatical system computer assisted for compensate the sag of an optoelectronical detector. This system is used for compensate the sag of a frame of an optoelectronical detector during the fabrication. For push-up group we use pneumatically servocylinders which allowed a very precise control of the sag through force. Each servo cylinder includes a proportional pressure regulator for regulating the pressure proportional to a specified electrical nominal value. The system is controlling by a PC with 2 acquisition board, one of them for monitoring the force of the transducer and the other board for controlling the pressure of the gas in servo cylinders. The software subsystem for developing the tuning numerical algorithm contents WIN 98 operating system, TestPoint rapid application development platform for data acquisition and graphic user software and Delphi rapid application developing platform for real time control algorithm module.
