Capacitive touch screens work by using the current sensing of the human body. When the finger touches the screen, due to the human body electric field and the surface of the touch screen to form a coupling capacitance, for high-frequency current, capacitance is a direct conductor, so the finger from the point of contact to suck away a very small current. This current flows from the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners of the controller through the precise calculation of the ratio of these four currents, the location of the touch point.
Capacitive touch screen is not only widely used in consumer electronic devices, but also in some industrial areas, such as mining equipment, plays an important role.
Application and function of capacitive touch screen in mining equipment?
Control and operation interface:
Capacitive touch screen as the control and operation interface of mining equipment provides intuitive and efficient operation. The operator can directly control the various functions of the equipment through the touch screen, such as starting, stopping, and adjusting parameters.
Part of the safety system:
Capacitive touchscreens can be integrated with the equipment's safety system so that when the equipment detects a potential safety risk, the display can show a warning message prompting the operator to take appropriate safety measures via the touchscreen.
How can capacitive touchscreens improve the efficiency and safety of mining equipment?
Improve operational efficiency:
Capacitive touchscreens provide an intuitive graphical interface that makes operation easier and faster. Compared to traditional mechanical buttons and switches, capacitive touchscreens can significantly reduce operating time and the potential for misuse.
Enhanced Data Visualisation:
Through the data graphs and real-time monitoring screen displayed on the monitor, operators can have a clearer understanding of the operation of the equipment and the progress of the mine, so as to use the touch screen to make more reasonable scheduling and decision-making.
Benefits of Capacitive Touch Screens：
Durability:
Capacitive touchscreens typically have high durability and are able to withstand the harsh environments of mining sites, such as dust and vibration.
High sensitivity:
Capacitive touchscreens are highly sensitive and can be easily operated by the operator, even when wearing gloves.
Easy maintenance:
Since the structure of capacitive touch screen is relatively simple, it is easier to maintain and replace.
Specific application scenarios：
Mining machine cockpit:
In the cockpit of mining machines, capacitive touch panels can be used as the main control and information display interface, providing various operational functions of the equipment and real-time monitoring data.
Mobile mining equipment:
For mobile mining equipment, such as excavators, loaders, etc., capacitive touch panels can be used to display the equipment's operating status, operational efficiency and navigation information.
Mining Monitoring System:
In the mining monitoring system, capacitive touch screen can be used as the central console to display the real-time monitoring screen, alarm information and data analysis results in the mining area.
