【Abstract】 A personal computer often takes a one-to-one mode to build a data acquisition system.Single serial computer can only acquire one sensor’s data at a time. How to design a distributing multitask data acquisition system of the personal computer? According to the experience in designing a vehicle navigation system, the authors introduced the technology of collecting the data sent by the HMR3300 magnetic sensor and the GPS receiver.It provides a complete solution of the data acquisition system.更多还原
