TL;DR: The practice shows that this scheme can not only effectively play performance of ordinary data acquisition card, but also reduce greatly program development time and beautify interface through LabVIEW which has powerfully visual human-machine interface editor and graphical programming function.
Abstract: Based on LabVIEW, this paper presents a design scheme of data acquisition, which it proposes using computer and ordinary data collection card as the main hardware and LabVIEW as software development platform, thus constructs the virtual instrument system for signal acquisition. The system can realize synchronous data acquisition of single channel or multi-channel signal, as well as real-time display and preservation. The practice shows that this scheme can not only effectively play performance of ordinary data acquisition card, but also reduce greatly program development time and beautify interface through LabVIEW which has powerfully visual human-machine interface editor and graphical programming function.

TL;DR: According to Dynamic Link Library (DLL), the common motion card was successfully run on Labview virtual platform, which can graphically compile program and indicated that each axis has three motion models of automatic, manual and return-to-zero, which could switch mutually at any time.
Abstract: According to Dynamic Link Library (DLL), the common motion card was successfully run on Labview virtual platform, which can graphically compile program. Based on Labview8.6 platform, Leadtech SMC-6480 control card and Yaskawa SJME-02AMA41 servo motor were used as the hardware to realize multi-axes motion control. The results indicated that each axis has three motion models of automatic, manual and return-to-zero, which can switch mutually at any time.

TL;DR: In this paper, a thermometer that uses infrared sensors to detect temperature without contact is designed, which can achieve noncontact measurement, place the thermometer in the forehead for a few seconds to get the body temperature, to alarm once the set value is exceeded.
Abstract: Due to the disadvantages of traditional mercury thermometers, such as longer measurement time and necessity of contact with the human body, a thermometer that uses infrared sensors to detect temperature without contact is designed. The Infrared temperature sensor MLX90614 is designed to collect human or object temperature by the SCM to process the temperature into the LCD display and alarm when over-temperature. Using software design to complete the control of the system. The smart thermometer can achieve non-contact measurement, place the thermometer in the forehead for a few seconds to get the body temperature, to alarm once the set value is exceeded. The design temperature range is 0-55 °C, and temperature resolution is 0.1 °C.

TL;DR: A method for HVCBs mechanical fault diagnosis utilizing variational mode decomposition (VMD) based on improved time segment energy entropy (ITSEE) and a new hybrid classifier model combined of one-class support vector machine (OCSVM) and probabilistic neural network (PNN) is proposed.
Abstract: In mechanical fault diagnosis of the high voltage circuit breakers (HVCBs), it is often expected that the fault type should be confirmed in time to avoid delaying the best time for mechanical fault diagnosis. The traditional diagnosis method of HVBC is not so profound for the identification of slight faults and does not consider the impact of the recall rate of fault samples on the fault diagnosis results. In this paper, we propose a method for HVCBs mechanical fault diagnosis utilizing variational mode decomposition (VMD) based on improved time segment energy entropy (ITSEE) and a new hybrid classifier. Firstly, the signal is decomposed into $K$ intrinsic mode functions (IMFs) via VMD to establish a component matrix. Secondly, the ITSEE method is used to calculate the energy entropy of the matrix in time domain and frequency domain, so as to better extract the features of slight fault types. Finally, an optimal hybrid classifier model combined of one-class support vector machine (OCSVM) and probabilistic neural network (PNN) is used to identify four types of vibration signals of HVCBs. The experimental results show that the accuracy of unknown samples is 98.75%, and the recall of fault type is 100%. The experimental results show the effectiveness of the method and have important application value for the diagnosis of HVBCs.

TL;DR: The results showed that the proposed wireless testing system for concrete rigidity based on virtual instrument had reasonable design, compact structure, complete functions, convenient operation and high accuracy.
Abstract: Concrete road constitute a high proportion of trunk highways and branch lines in China. As an evaluation index of concrete road quality, concrete rigidity has become an important performance parameter. Consequently, testing the concrete rigidity of concrete road is absolutely necessary during the road construction and acceptance in order to assure the quality and durablity of road. A wireless testing system for concrete rigidity based on virtual instrument was proposed in this paper. C8051F040 and wireless transceiver module nRF905 were used to build the wireless data transmission system hardware platform of lower computer. LabVIEW was used as the system's development platform of upper computer, meanwhile, NRF905 and Atmega16 were combined to receive concrete rigidity data from lower computer through the wireless communication. The results showed that this system had reasonable design, compact structure, complete functions, convenient operation and high accuracy.
