In the building automation management system (BAS), touch screen as the core equipment of human-machine interaction (HMI) can significantly improve the system's ease of use, management efficiency and response speed. The following is an analysis of its specific application scenarios and advantages:
1. Typical application scenarios of touch screen in building automation
(1) Central monitoring room
Function: Integrated display of real-time data of HVAC, lighting, security, energy management and other subsystems to support global control.
Advantage: Quickly locate problems and reduce operation complexity through visualization interface (e.g. floor plan, dynamic flow chart).
(2) Public area (lobby, elevator hall)
Function: for visitors or property staff to query building information (e.g. navigation, meeting room booking), adjust environmental parameters (e.g. air conditioning temperature).
Advantage: no need for professional training, intuitive operation to enhance the user experience.
(3) Equipment room (e.g. air conditioning room, power distribution room)
Function: On-site debugging or maintenance of equipment, view real-time operating parameters (such as pump pressure, energy consumption curve).
Advantage: Replaces the traditional button panel, saves space and supports remote diagnosis.
(4) Conference room/intelligent office
Function: One button to control lighting, curtains, projector and other equipment, preset scene modes (e.g. “meeting mode”).
Advantage: Simplify the cooperative operation of multiple devices and improve office efficiency.
(5) Energy Management Station
Functions: visualization of energy consumption data, support for time-phased strategy adjustment (e.g. optimization of peak and valley tariffs).
Advantage: Assist energy-saving decision-making through chart analysis.
2. Core advantages of the touch screen
(1) Intuitive operation
The graphical interface (GUI) replaces complex menus or physical buttons, reducing the rate of misoperation, especially suitable for non-technical personnel.
(2) Space and cost optimization
Integrate the functions of multiple traditional control panels to reduce the number of hardware and lower installation and maintenance costs.
(3) Real-time interaction and feedback
Dynamically updates data (e.g. temperature changes, alarm status) and supports quick response (e.g. acknowledging fire alarms).
(4) Enhanced user experience and satisfaction
Self-service: visitors can query and navigate through the touch screen in the public area, and the touch screen allows customers to interact intuitively, enhancing their sense of experience.
Interaction friendliness: the touch screen can support gesture operation: drag and drop, zoom and other gesture operations are more in line with modern habits of use, reducing training costs.
(5) Enhanced Security
Identity authentication (fingerprint, password) can be integrated to limit the rights of different users (e.g. only allow engineers to modify parameters).
3. Actual Case References
(1) Intelligent Building: CapitaGreen Building in Singapore adopts the touch screen central control system to reduce energy consumption by 30%.
(2) Hospital buildings: Charité Hospital in Germany unified management of the ward environment through the touch screen to enhance patient comfort.
Touch screen in building automation is not only an interactive tool, but also a key node to optimize the management process and reduce operation and maintenance costs. With the development of IoT and AI technology, its role will be gradually upgraded from “control terminal” to “intelligent decision-making terminal”.
