Abstract: This paper mainly in combination with RFID to construct a set of power system equipment remote control, first on the tags reader received after the use of Visual Basic to determine the signal and transmits the signal via the RS232 cable to the control circuit 8051 to control the instrument power switch. The topic written in Visual Basic RFID, using features such as: personnel control systems, access control systems are derived from the time of access control systems, many instrument control systems, and use the records stored in the form of the function, the other circuit is transmit signals to Visual Basic 8051, then by 8051 to control the instrument power switch.

Abstract: Undertake the study of the topic home monitoring system, the wisdom of building the health care environment monitoring and automation control systems, sensor signal is transmitted through ZigBee wireless technology and NI data acquisition card to do transfer cable transmission technology. In addition, an infrared remote control technology for automation and control for air conditioning. Improvements in the system developed sensors were temperature, humidity, carbon monoxide, illumination, and sensor signal transmission through wireless technology and cable transmission technology, to the terminal for processing, record, query and other features, then the terminal through RS -232 assigned for IR control module control packets, and output through PPM IR code to the IR receiver, and thus control of indoor air conditioning.

Abstract: For factory automation, devices and machine make a lot of space has become crowded and full of workers makes the operation of the pipeline space is limited, the problem of accidents become more frequent as the frequency will gradually floating surface have to seriously. The combination of embedded systems based on ZigBee technology to enhance the quality of research objectives of industrial safety, in addition to the general control inherent in using the system outside the ZigBee wireless technology to a remote control. Industrial application platform measurements have the thickness of the degree of screening, vibration sensor, weight classification, current sensing, energy monitoring, load switching, temperature monitoring, and carbon dioxide concentration. From the existing literature found in this study combined with embedded ZigBee for industrial real-time measurement system is an innovative technology. In this study, in addition to the discussion platform, the data for statistical measurement and analysis are also discussed in detail, through wired and wireless synchronization of the system measurement and monitoring, will be able to reach a real-time and can improve the safety of plant safety monitoring.

Abstract: This system was composed of independently developed ECG Signal Acquisition Model, DAQ Signal Acquisition Card, and the LabVIEW Graphics System. Regarding the ECG Signal Acquisition Model, this system uses the TL082 Operational Amplifier to realize the amplification, and uses the Filter Circuits along with the ISO122 to isolate IC. Regarding the ECG oscillogram display and ECG Signal Acquisition, the LabVIEW Graphics System developed by the American company “National Instruments” (NI) was adopted. Also, the LabVIEW system and the DAQ signal acquisition card of the Data Acquisition Package developed by the NI Company was adopted as well.The DAQ signal acquisition card can engage in A/D, DI/O, number counting and time counting applications. At last, it can use the TCP/IP Protocol to send the ECG waveform data by the internet to the computers with remote surveillance monitors. The remote surveillance computers can be installed in the hospital. Professional doctors in the hospital can observe the patient’s ECG waveform data and statistics, and engage in the job of remote care.
