Ventilation monitoring and control system for high rise historical buildings

Adequate ventilation system and difficulty in operating/maintain ventilators at higher levels in temples and high rise historical buildings is a major problem. In this regard a wireless sensor actuator network based ventilation monitoring and control system is developed for temples and high rise historical buildings. Sensor array modules are implemented successfully. ZigBee communication module for transmitting real-time data to the control room is being used. Machine-to-machine communication of the exhaust fans and the control Apps with PC (personal computer) was successfully carried out. Developed system is capable of online monitoring of exhaust fans running information parameters such as air flow, vibration, rpm (revolutions per minute), and load. The system is also capable of ventilation control for good indoor air quality based on real-time monitoring of environmental parameters like as CO₂, temperature and relative humidity. A graphical user interface (GUI) for monitoring and control ventilation with the exhaust system was developed. Exhaust fans real-time information and environmental parameters values are displayed on the GUI developed using Visual Studio C# language. Calibration of the sensor module and exhaust system has been implemented successfully and they assure that the desired accuracy is sustained after a time interval. Developed system is of low cost, energy efficient, easy to operate with high accuracy.
