A New Remote Monitoring System Application in Laser Power Based on LabVIEW

MATEC Web of Conferences, Jan 2016

In this paper, a new remote monitoring system based on LabVIEW was proposed to measure laser power automatically and remotely. This system consists of four basic components: an DH-JG2 optical power meter, a NI-USB 6008 data acquisition card, a personal computer (PC), and HP laserJet 1020 Plus printer. Since power output of laser is generally so unstable that abnormal work situation could not retroaction to inspectors right away, new system was designed to solve this problem. The detection system realized function of remote control by TCP protocol and mobile phone. Laser power curve that is measured by detection system demonstrated that the design has a good performance in real-time detection and operability.

A New Remote Monitoring System Application in Laser Power Based on LabVIEW

MATEC Web of Conferences A New Remote Monitoring System Application in Laser Power Based on LabVIEW 0 Fuzhou , 350007 , China 1 Gaoqiang Liu , Weilin Wu, Mingyu Liu, Kun Zhang and Guannan Chen 2 Key Laboratory of Optoelectronic Science and Technology for Medicine, Ministry of Education In this paper, a new remote monitoring system based on LabVIEW was proposed to measure laser power automatically and remotely. This system consists of four basic components: an DH-JG2 optical power meter, a NI-USB 6008 data acquisition card, a personal computer (PC), and HP laserJet 1020 Plus printer. Since power output of laser is generally so unstable that abnormal work situation could not retroaction to inspectors right away, new system was designed to solve this problem. The detection system realized function of remote control by TCP protocol and mobile phone. Laser power curve that is measured by detection system demonstrated that the design has a good performance in real-time detection and operability. 1 Introduction Laser is the important component of technologies in the field of communication, manufacturing, as well as optical experiment because of its characteristics including high brightness, good monocolor, good coherence as well as good direction. However, as far application, one of the main problems is that its output power is not stable and the laser is easy to be destroyed because of transient circuit and voltage peak[ 1 ]. Lots of power meters were invented for measurement in the process of laser manufacture last decades. With the rapid development of the computer technology, manual operation desktop machines have the disadvantages of low efficiency, inconvenient data analysis and storage in the quality of laser testing[ 2 ]. Therefore, software-based automated testing system design is imperative. Measurement system of laser power in VC++[ 3 ], the software of optical power measurement and calibration and instrument control system based on LabVIEW have overcame the lack of the manual operation desktop machines, but they remains to be more automatical, and errors in the testing process can’t be managed when failed in working in time[ 4 ]. With the rapid development of the computer technology and the software technology, there are more and more kinds of software development platforms and instrument functions which can be achieved by computers and related software NI-LabVIEW[ 5 ]. LabVIEW produced by National Instruments is the most widely used as virtual instrumentation system. It has the development and debugging tools of traditional programming language. The greatest feature of LabVIEW is the graphical programming language, which is easy to grasp, understand develop a friendly, realistic user interface. Furthermore, it has the powerful signal processing ability, and integrates almost all of the features of hardware communications such as data acquisition card. Virtual instrument is an individual computer testing equipment that has a virtual instrument panel. It brings a revolutionary change in the field of automatic testing system. To a testing platform, LabVIEW includes the storage functions of data collection, processing and analysis. To meet the needs of various practical applications toolbox, it can use dynamic link (DLL) technology to users of the virtual instrument software to link to them. use links embedded object (OLE) technology will be embedded in other virtual instruments. LabVIEW offers a numbers of source-level instrument drivers, including DAQ, GPIB, PXI, VXI, RS232 as well as USB, users can choose their own hardware drivers according their own needs[ 6 ]. In this paper, a remote monitoring system in laser power based on Labview was designed and implemented. The system used optical power meter DH-JG2 as monitoring laser power component produced by DaHeng. NI-USB 6008 data acquisition card was utilized to collect the power data from power meter. A electrical energy supply system HSPY_36_03 produced by HSPY was employed for turning on or off the laser, Also HP laserJet 1020 Plus as the output device of the test report. Besides, using the real time software LabVIEW displayed and analyzed the power data, and a mobile phone was used to remotely monitor. 2 System composition System design framework is shown in fig. 1, from which we can see the system consisting of Laser, power meter, data acquisition card, printer, PC machine, electrical energy supply system as well as mobile phone. In which, DH-JG2 is the power meter, responsible for collecting the actual laser power data, and outputting voltage signals. And the USB 6008 is a data acquisition card produced by NI(National Instrument), can collect voltage signals from DH-JG2, convert the signals into digital signals and send the digital signals to the PC machine by USB bus[ 7 ]. On the one hand, PC machine displays and analyses the power data, and generates a test report and sends it to the HP laserJet 1020 plus and then the repor (...truncated)
