在线式UPS因具有零切换时间、供电时间长、供电质量高等优点,在对交流供电的可靠性以及供电质量要求高的场合得到了广泛应用。在线式UPS的稳定性对于用电设备的可靠运行具有重要意义,因此需要对在线式UPS运行状态进行监控。监控系统采用了TMS320F28335型号的DSP处理器并结合变压电路与模拟温度传感器实现对UPS电压、温度等运行状态信息的采集。最终经由以太网络将数据传输至上位机,利用上位机中编写的监控软件实现了对UPS运行状态的实时监控。
Because of the advantages of zero switching time, long power supply time and high power supply quality, on-line UPS has been widely used in applications where the reliability of AC power supply and power supply quality are high. The stability of the on-line UPS is of great importance to the reliable operation of the electrical equipment and therefore requires the monitoring of the on-line UPS operating status. Monitoring system uses a DSP processor TMS320F28335 models and combined with transformer circuit and analog temperature sensor to achieve UPS voltage, temperature and other operational status information collection. Finally, the data is transmitted to the host computer via the Ethernet. The monitoring software written in the host computer realizes the real-time monitoring of the UPS running status.
