The system can test eight products parallelly. It reduces the test cost and improves work efficiency. The paper also gives the hardware structure and software flow diagr am of the system. The application in the gyro test is also introduced briefly. Key words:communication prot;data acquisition; gyro; test With the development of computer technology and the digital measuring instrument, usually by computer and measuring instruments to communicate with each other in real-time data collection and use of computer powerful computing capability to conduct the analysis of the data processing. Particularly in the large volume of data, measuring the length of time occasions, such as the Gyro-tilt test, using computer for automatic control of measuring instruments, automatic data acquisition and analysis it is particularly important, can save a lot of manpower and material resources to improve work efficiency, reduce costs , The conventional method of testing is usually a measuring instrument at the same time can only test a product, namely a computer and a measuring instrument test system can only be composed of serial testing. To test multiple products at the same time, they need multiple systems, testing products in large volume, low efficiency, such as the composition of several sets of test system, an increase of cost. First on a machine with a PC and a measuring instrument consisting of 8-way data collection and analysis system, which can carry out multiple sets of product testing, at no additional cost on the basis of a computer give full play to the advantages of automatic test, Improve work efficiency. 1 Principle The system hardware and software system. A PC through a RS232 port and a measuring instrument connected, PC-parall
