Siemens PLC-Based Fan Unloading Pressure Monitoring and Alarm System Solution

In the production and conveying process of powdered raw materials, monitoring the pressure in the conveying pipeline at the fan outlet is of utmost importance.

 If the pressure exceeds the control range, it may lead to blockages in the conveying pipeline, and in severe cases, halt production. Conversely, if the pressure is too low, subsequent operations may not proceed normally.

A Siemens PLC-based fan can achieve stable pressure control and intelligent alarms.

 Users can set different trigger conditions in the PLC programming software according to their actual needs, such as changes in input signal status or a value exceeding a set threshold. When these trigger conditions are met, the PLC will activate corresponding alarms. At this point, the WideIOT Industrial Smart Gateway can capture these alarm data and upload them to the monitoring center cloud platform, enabling alarm notifications through various channels such as the platform, WeChat, SMS, and email. This helps enterprises stay informed about the outlet pressure at all times and strictly manage and control it.

Implemented Functionalities:

1. Real-time Monitoring: By utilizing pressure sensors and PLC data acquisition, the system continuously monitors the fan unloading pressure and transmits the data to the cloud platform or an upper computer for visualization.

2. Data Communication: The Industrial Smart Gateway provides multiple internet connectivity options, including 5G, 4G, WIFI, and Ethernet, ensuring reliable data transmission and real-time communication.

3. Over-limit Alarms: When the pressure exceeds the set threshold, the system triggers an alarm device to automatically generate alarms, displaying the alarm information through various methods.

4. Remote Monitoring: Through internet-enabled devices, real-time pressure data and alarm information are transmitted to a remote monitoring center, enabling remote monitoring and management.

5. Remote Maintenance: By utilizing device maintenance express lines, the system allows for remote programming, debugging, and uploading/downloading of PLC programs, enhancing operational efficiency.
