The Special-Purpose Test Adapter Design In Surveying System

The surveying system need to simultaneously complete integrative testing and control task of three set of product, shorten much product technology preparing time and improve effect. design the Special-purpose testing adapter in the article, the equipment is a measure key parts of the surveying system, direct connected with product control system, can automatically test of the product. Aims at the special-purpose adapter in the article, according to the demand for product testing, complete analysising the specific test signal of the surveying system test special-purpose adapter, signal characteristics of the test for independence into the functional test modules, make full use of programmable component integration advantages, make use of programmable component and PC104 bus technology to complete the hardware circuit design, including the counting circuit, data acquisition circuit and control output circuit, power module, and other functions, in the design mainly uses the hardware description language,the programmable component program to realize the electric circuit control. The system through the test confirmation, have designed to meet the technical requirements, the design product special-purpose test adapter has realized the product test demand, may complete the test task completely.
