The touch screen connects with computer or other electronic devices through USB interface to realise data transmission and command reception. This kind of touch screen device is widely used in industrial control, advertising, intelligent home appliances, robotics and other fields, and is favoured by users for its plug-and-play, easy operation and stable performance.
Working principle:
The working principle of USB interface touch screen mainly involves USB HID (Human Interface Device) protocol and touch screen technology. The computer identifies the touch screen device through the USB interface and loads the corresponding driver. The driver follows the USB HID protocol and communicates with the touch screen device to obtain information such as touch position and gesture, and transmits it to the operating system. The operating system processes the data received and realises the interaction between the user and the device.
The technical characteristics of the touch screen USB interface:
1. Plug and play: the USB interface touch screen supports hot plug and play, the user does not need to shut down the computer to connect the device to the computer, greatly improving work efficiency.
2. fast transmission speed: the USB interface has a high data transmission rate, to meet the requirements of real-time and accuracy of touch screen equipment.
3. Strong compatibility: USB interface is a widely used standard interface, has good compatibility, can connect a variety of operating systems and devices.
4. good stability: USB interface touch screen in the process of data transmission and command reception shows good stability, to ensure the smoothness and accuracy of user operation.
Application Scenario:
1. industrial control: in the field of industrial automation, USB interface touch screen as a human-computer interaction interface, to achieve the remote control and monitoring of production equipment.
2. Advertising: In the advertising industry, USB interface touch screen can be used to make interactive advertising machine to improve the fun and attraction of advertising.
3. Intelligent home appliances: With the development of smart home, USB interface touch screen is widely used in refrigerators, washing machines and other home appliances to achieve intelligent control and operation.
4. Robotics: In the field of robotics, the USB interface touch screen is used as the control panel of the robot, providing an intuitive and convenient operation.
When choosing a USB interface touch screen, users need to make comprehensive considerations based on their actual needs and budget. Here are some selection suggestions:
1. Consider the touch technology: resistive touch screen, capacitive touch screen and other different touch technologies have different characteristics and scope of application, users need to choose according to the actual needs.
2. Focus on interface compatibility: Ensure that the touch screen device is compatible with the interface of the computer or other electronic devices.
3. Consider the performance and stability: choose stable performance, high reliability of the touch screen equipment to ensure long-term use of the effect.
