The modern data acquisition system gradually develops in the direction of strong real-time, multi-parameter, high-precision, and large-capacity. For this reason, this article has designed a kind of data acquisition system with strong real-time and can be stored in the database. The controller in this system is designed based on the LPC1769 chip and realizes multi-module plug-and-play expansion. The computer program is achieved by C# language, supported by Iocomp Component Library to build the UI interface, and completes the storage and management of large amounts of data by using SQLite Database. Data is transmitted between the computer and the controller according to the serial protocol. In order to improve the accuracy, the system also provides the ADC self-check function. The embedded data acquisition system can collect data in real time by the controller, and can provide comprehensive data with acquisition time as in the test. The storage of the data can be performed by the computer program, both the dynamic and static curve of the data can be displayed and the analysis of the data can be completed.
