Abstract: A data acquisition system based on LPC2214 microcontroller is designed. The system has strong real-time performance, high sampling precision, small volume, large storage capacity, strong versatility and flexible communication mode. The data acquisition system is an important part of the industrial measurement and control system and intelligent instrumentation, and the traditional data acquisition system based on the single task sequence mechanism is difficult to meet the requirements of high stability and real-time requirements. Therefore, this paper designs an embedded wireless data acquisition system based on LPC2214 single-chip microcomputer. The system block diagram is shown in Figure 1. The system relies on the existing GRPS wireless network, with simple networking, reliable performance and low operating cost. It is especially suitable for occasions where the collection points are widely distributed, the number is large, the distance is long, the place is remote, and unattended.
