Design of portable system for field sensor in-situ data acquisition

Aiming at portable and efficient requirements for data acquisition system in geology inspection field, a set of portable system for field sensor in-situ data acquisition is designed. The overall design idea, hardware and software platform architecture and redization scheme of all the system components are introduced in detail. The designed system has the advantages of miniaturization, in-situ, lower power consumption, mobile and strong commonality, which are in favor of in-situ measurement and inspection periodically. The system can automatically save information of time, temperature, humidity, parameters of sampling point, sensor type, sampling data, and so on, and parameters configuration acquisition system and off-line management of sampling datas by data management system running in PC. The system is reliable, portable, man-machine harmony, a large amount of data storage, high cost-effective, good performance of movement is suitable for all the conventional sensors, and can meet the needs of parameter measurements in the field inspection fields.
