Methods: Using signal detecting and data processing techniques, this monitor with a graphic liquid crystal display (LCD) and a single-chip microprocessor 8Xc196Kc can dynamically measure electrocardiogram(ECG), breath wave, blood pressure (BP), breath frequency (BF), heart rate (HR) and body temperature (BT) in real-time. Results: This monitor can dynamically display the ECG, breath wave and other parameters in real time. It can also provide a 24h trend graph for each measured parameter and exchange data, through the serial communication interface (RS232), with the PC or hand-held PC (HPC). Conclusions: This portable monitoring system has a man-machine interface friendly. It is capable of performing continuous monitoring and also used as terminal of a central monitoring system or a tele-monitoring system.展开更多

The draw-out power coil can induce voltage from the transmission line, using single-chip microcomputer to analog and output PMW wave to control the charging module, provides a stable 3.4 V DC voltage to the load, and solve the problem of easy saturating of core. The power supply based on this kind of draw-out power coil has undergone the overall testing, and it is verified-showing that it can properly work in a non-saturated status within the current range of 50 - 1000 A, and provide a stable output. The equipment also design protection circuit to improve the reliability to avid the impacts of the impulse current or short-circuit current. It effectively solves the problem of power supply for On-line Monitoring System of Transmission.展开更多
