Contrary to the problem that automobile switches have various kinds and large differences in the structure and performance so that traditional testing methods have been unable to meet the testing requirements of high performance switches, the paper designs a new detection system used to detect the functions of general auto switches which applies the developing environment LabVIEW based on virtual instrument technology and adopts the technology of embedded observe and control system. Using PC as the host computer, the system adopts the LabVIEW8.5 to compile a real-time monitoring system with good human-computer interface; S3C2440-ARM9 processor is used as the main controller of observe and control system in the inferior computer which collects output current signal when the circuit is conducted after switch is pressed. After the coding process of LwIP software protocol and the drive of Ethernet controller DM9000, the signal is transmitted to PC through Ethernet interface. Compared with conventional testing measures, this system greatly improves the real-time performance as well as working efficiency of detecting switch functions and reduces the corresponding human and material resources.

Accurate detection of the direction of hydraulic fracturing cracks in the oil field is one of the crucial factors in rational exploitation of the remaining oil and enhanced oil recovery. In this paper, using the potential and the potential gradient test methods and virtual instrument technology, we design and develop an intelligent borehole-surface electrical method multi-parameters detection system (BEMDS), which can achieve multi-channel, multi-parameter and high-precision borehole-surface electrical method data acquisition. Joint programming technology of Labview and Matlab gains the simultaneously measurement of the parameters of resistivity and induced polarization. As a result, the drawbacks of the original instrument that measuring single parameters and cannot mutually authenticate has been overcome.
