Applications of IoT Systems in Smart Buildings

A smart building refers to a modern building form that undergoes a comprehensive upgrade in operations, management, and services with the support of digital and intelligent technologies. Among them, the Building Automation System (BAS) is a crucial core. It integrates numerous decentralized equipment systems within the building, such as HVAC (Heating, Ventilation, and Air Conditioning), water supply and drainage, power supply and distribution, elevators, and heating, into a single system platform. This system enables centralized monitoring, management, and decentralized control over the operation, safety status, energy usage, and energy-saving management of each equipment.

In this context, WideIOT provides an IoT solution for connecting PLCs (Programmable Logic Controllers) in smart building control systems. By integrating industrial smart gateways into PLCs, it realizes functions such as data collection, remote monitoring, remote management, operation and maintenance management, and data analysis, offering reliable assistance for enhancing the management level and digitalization degree of smart buildings.

1. Water Supply and Drainage System:
   The water supply and drainage system is an indispensable and vital component of any building, encompassing water supply systems, drainage systems, and fire protection water systems. By integrating WideIOT's industrial smart gateways, real-time monitoring of water tank levels, pump operating statuses, and supply/drainage flow and pressure can be achieved. Automatic alarms can be triggered in case of abnormalities, enabling timely measures to be taken for management and control, ensuring the safe and stable water supply for building residents.

2. Lighting System:
   The PLC-controlled lighting system can automatically switch on and off at different times to meet the lighting environment requirements. By integrating industrial smart gateways, data such as switch statuses, switch times, and energy consumption can be collected and centralized in the smart building platform. This enables real-time monitoring of the lighting systems on each floor, quick identification of faulty equipment, and the formulation of scientific and reasonable energy-saving strategies to achieve intelligent lighting.

3. Air Conditioning System:
   Equipment such as air conditioning units, fresh air units, and variable air volume units are also significant energy consumers in buildings. By continuously collecting and monitoring the operating conditions of air conditioners, including return air temperature, return air humidity, and the operating statuses of compressors and dehumidifiers, the air conditioning operating strategy can be reasonably adjusted, and operation and maintenance plans can be arranged appropriately. This not only ensures the safe and efficient operation of the equipment but also achieves energy conservation, cost reduction, and improved energy efficiency.
