When the maximum value exceeds the preset threshold, the control unit controls the alarm to sound an abnormal alarm, close all valves in time, and carry out maintenance.

[0052] The working principle and beneficial effects of the above technical solution are as follows: Working principle: On the basis of Example 2, a vibration control and abnormal alarm module is added. This module detects the key parameters of compressed air in the system in real time through a variety of sensors, including density, pressure, air pressure, flow rate, temperature, etc.; these sensors transmit data to the control unit, and the control unit regularly collects and processes these data at set time intervals. Calculation module one and calculation module two respectively calculate the exergy loss assessment value in the cylinder barrel and other exergy loss abnormal assessment values ​​when the compressed air drives the piston to vibrate based on specific formulas. The comparison and judgment module compares the calculated abnormal assessment value with the preset threshold range to determine whether the system is in a normal state.

[0053] When the system parameters are normal, the alarm will not be activated. If the abnormal evaluation value is lower than the minimum value of the preset threshold, the control unit will increase the input pressure of the intake pipe 33 until it reaches the preset threshold. If the abnormal evaluation value exceeds the maximum value of the preset threshold, the control unit will trigger the alarm to alarm abnormality and close all valves to ensure system safety and facilitate maintenance.

[0054] Beneficial effects: Real-time monitoring and early warning: Through real-time monitoring of key parameters of the compressed air system through density sensors, pressure sensors, air pressure sensors, flow rate sensors and temperature sensors, potential problems can be discovered and warned in time, improving the stability and safety of the system.

[0055] Accurate assessment and control: The calculation module calculates the exergy loss assessment value and abnormal assessment value based on precise formulas, providing data support for the precise control of the system. By comparing the judgment module with the preset threshold, it can achieve an accurate assessment of the system status and take corresponding control measures.

[0056] Automatic control: The control unit can centrally control and process data, and perform regular inspections and evaluations at set time intervals, thus realizing automatic control of the system. This reduces the frequency of manual intervention and improves work efficiency and system reliability.

[0057] Fast response to faults: When the system is abnormal, the alarm can sound an alarm in time and close all valves to prevent the fault from expanding. This helps to quickly locate the fault point, shorten maintenance time and reduce maintenance costs.

[0058] Improve energy efficiency: Through real-time monitoring and precise control of system parameters, the use efficiency of compressed air can be optimized, energy waste can be reduced, and overall energy efficiency can be improved.
