Uninterruptible Power System (UPS) is a kind of power protection equipment which contains energy storage device, with inverter as the main unit, capable of stabilising voltage and frequency output.UPS system is mainly composed of several parts, such as battery pack, rectifier, inverter and static switch, etc. When the external power (utility power) is normal, UPS system converts AC power to DC power through rectifier and charges the battery; when the external power is interrupted, the battery converts DC power to AC power through inverter. When the external power supply (utility) is normal, the UPS system through the rectifier will be converted to DC power and charge the battery; when the external power supply is interrupted, the battery through the inverter will be converted to AC power, to provide uninterrupted power supply for the loads.The UPS system is widely used in the fields of computer security, transportation, aerospace, medical, industrial control, etc., to ensure that the key equipments can still operate normally when the power fails. UPS systems are widely used in computer security, transportation, aerospace, medical, industrial control and other fields to ensure that critical equipment can still operate normally when power fails.
The application of touch display in UPS system is mainly reflected in the following aspects:
1. Status monitoring and display: through the display, users can intuitively view the various parameters and status of the UPS system, such as input and output voltages, load percentage, battery capacity, utility status and so on. Users can manage this information in real time through the touch screen to help users quickly understand the operation of the UPS system.
2. Fault alarm and diagnosis: When the UPS system failure, the touch screen display can show fault information, including faulty parts or devices, to help users quickly locate the problem. At the same time, some advanced UPS systems also have a ‘black box’ function, can record the key parameters and waveforms before and after the event, to provide detailed data for failure analysis.
3. Maintenance and management: touch screen also provides UPS system maintenance and management functions, such as battery testing, life prediction, system self-test. These functions help users find potential problems in time and take appropriate measures to ensure the long-term stable operation of the UPS system.
Advantages of the touch screen in the UPS system:
1. intuitive and easy to use: touch screen interface is friendly, easy to operate, users can quickly get started without professional training.
2. real-time monitoring: touch screen can display the real-time UPS system parameters and status, to help users master the system operation at any time.
3. Enhanced interactivity: touch screen using an intuitive graphical user interface (GUI), the user can touch the screen icons, buttons and other controls for operation, without the need for complex keyboard input or menu navigation.
Touch display application in the UPS system challenges:
1. Complex environment adaptability: UPS systems may be deployed in a variety of complex environments, such as high temperature, high humidity, dusty, etc., which puts higher requirements on the durability and stability of the touch screen.
2. Touch accuracy and response speed: In some occasions that require high operating accuracy and response speed, the performance of the touch screen may become a limiting factor, for example, we all know that there is an electrical capacity of water, and the capacitive touch screen may have the risk of false touch in an environment with water.
Solution:
1. Enhance the environmental adaptability: adopt high protection level touch screen and housing materials to improve the adaptability of the UPS system to complex environments. At the same time, strengthen the heat dissipation and dustproof design to ensure long-term stable operation of the system.
2. Optimise touch performance: Choose high-performance touch screen hardware and optimised software algorithms to improve touch accuracy and response speed. Add anti-false touch and gesture recognition functions at the software level to enhance user experience.
