Application of industrial monitor in outdoor query

With the rapid development of electronization and informatization, various electronic information service systems have sprung up in various information gathering points in the city. City communication and self-service information inquiry systems more need to set up self-service electronic service systems outdoors to meet the needs of daily life and ordinary people. With the rapid development of informatization, the market demand for more outdoor and semi-outdoor query terminals is rapidly expanding.

The self-service inquiry terminal completely serving the outdoors has strict requirements on the terminal equipment due to the characteristics of the use environment and users. In the part of computer and related external equipment, it must be able to withstand the change of high and low temperature, withstand malicious damage, and at the same time, it must be able to achieve the lowest maintenance cost.

The business characteristics of outdoor inquiries and services, and the use and safety considerations of completely unknown people make the selection of touch screens for outdoor service terminals more demanding. With the current technology, the best choices for touch screens suitable for financial services are capacitive sensing touch screens, infrared touch screens, five-proof surface acoustic wave screens and anti-riot surface acoustic wave screens. Other devices that are completely used indoors and in places with security intervention also use the five-wire resistive touch screen solution.

Capacitive Sensing Touch Screen

Capacitive sensing touch screen is currently the only touch product that can fully realize waterproof, dustproof and pollution-proof after achieving anti-scratch and anti-riot performance. It can be used in outdoor and semi-outdoor special environment applications, and basically meets all the needs of automatic service in the early stage when it cannot be used except wearing gloves.

Infrared Touch Screen

Infrared touch screen is also the most widely used product in outdoor self-service. Infrared products have better performance than capacitive screens in terms of scratch resistance and anti-riot performance; but in terms of complete waterproof and dustproof performance, their performance is weaker than capacitance and resistance products. Because of heavy rain or a large amount of pollution accumulation, it will still affect the normal operation of the infrared screen. However, the system resumes operation as soon as the contamination is cleared.

Five-proof Surface Acoustic Wave Touch Screen

Five-proof surface acoustic wave touch screen, the world’s first five-level protection surface acoustic wave touch screen. Due to the technical characteristics of surface acoustic wave touch screens, the protection against dust and water and pollution is the weakest. The protective system established with the original ABS plastic mold structure, the protective mold is sealed by special waveguide material, and the liquid can be completely soaked for 100 hours without intrusion, effectively preventing the impact of liquid and dust accumulation on the touch screen, making the touch Applications can be resumed immediately after the screen is cleaned. However, the protection of the five-proof screen is a container-type protection method. When it rains or a large amount of pollution gathers, the normal operation of the touch screen will still be affected.

Anti-vandal Surface Acoustic Wave Screen

The anti-vandal surface acoustic wave screen is also a widely used product in outdoor self-service. This product is superior to capacitive screens in terms of anti-scratch and anti-riot performance; however, it is obviously weaker than capacitive and resistive products in terms of complete waterproof and dustproof performance. Device manufacturers can adopt a dust-proof strip sealing method to achieve moderate dust-proof and slight waterproof functions of the screen.
