The technology of data acquisition is the important branch of information science, it not merely employs in intelligent instrument, and in modern industrial production, military science is used widely, no matter proceeding control, condition monitoring, or failure diagnosis, quality detection, all due to data collecting systems. Because one-chip c

omputer powerful and antijamming capability strong and reliability high and flexibility fine developing advantaging such as being easy, have made on the basis of the one-chip computer is a central data collecting system is widely used in a lot of fieldsed. What the data collecting system based on one-chip computer usually adopts is two kinds of methods to realize data acquisition: One kind is to make the collecting part of the data into the plate card to insert in the computer expansion slot and realize data acquisition, namely A/ D switching device is connected with bus interface of the computer directly. Such way based on system integration data collecting system of the computer, can shorten lead time, thus accelerate the job schedule, but the configuration of hardware lacks flexibility, non- portable and using whenever and wherever possible. Another method is to make the collecting part of the data into the independent system, there are one`s own microprocessors, the computer passes serial port and data acquisition unit communication, thus realize data acquisition. The transmission over radio demonstrates very great flexibility in the treatment after data acquisition, save the intricate circuit, can realize easily many people share in real time, so we must launch the continuous data after test out in order to let more persons utilize. Test machine format transmission to want, design one can to carry on wireless emissive...
