An air compressor’s main function is to convert power into potential energy stored in pressurized air. The compression creates energy which can be utilized to power a variety of industrial application tools and instruments. Compared to using a centralized power source, air compressors are much more sustainable, smaller in size and do not require a massive motor to run. They’re also highly portable, quieter and more durable.
Requirements
- To monitor air compressor related parameters remotely and locally.
- The parameters which include as listed below:
- Temperature
- Vibration
- Run/Trip and Standby/Duty status
- Air pressure
- Air Dewpoint
- Air Flow Rate
- Totalizer (Daily, Yesterday, and Cumulative Total)
- To control air compressor to run based on setpoint settings
- Fail changeover as well as assist control when one air compressor cannot achieve desired pressure
- Daily report and alarm email and SMS notification
- Data logging
Solution
- The system was provided with public IP for remote monitoring as well remote control.
- To fulfil the monitoring and control needs of the plant, the following instruments are installed:
- Pitot tube air flow meter
- Dew meter
- Temperature sensor
- All the parameters are shown in the HMI.
- Program of auto changeover (Daily/Weekly/Monthly) is deployed.
- Program of standby and assist sequencing is deployed (based on setpoints).
- The system also can run manually when needed. System selector between Auto and Manual is provided.
- Daily report is being sent daily (settable).
- Phone number and email address settings provided for alarm SMS and email notification.
- Data logging is categorized into two parts: Totalizer and parameters.
Conclusions
- The overall system is working in good condition. The daily report SMS and alarm SMS helps the user the act promptly.
- The system can be monitored remotely and any time.
