Touch control machines, commonly known as touch inquiry all-in-one machines, are currently the most concentrated touch inquiry device for touch screen applications in China's IT industry. The all-in-one touch query machine, which entered China's information service industry in the 1990s, has experienced a decade of development and has become a leader in informatization construction. With the rapid development of electronic and informatization of the Chinese government, various electronic information service systems have sprung up at various information gathering points in the city, serving various application places such as shopping malls, airports, stations, exhibitions, and government affairs. It has played an increasingly important role in China's informatization construction and services.
The touch query all-in-one machine is an integrated system that uses a touch screen as a user interface. Through the organic combination of hardware configuration and application software, it realizes information publishing, information query, and information sharing. After the addition of functional devices such as card readers, micro printers, passbook printers, telephone equipment, and bar code equipment, a touch query terminal serving all walks of life will be formed.
The touch query all-in-one machine uses the touch screen as the only interface and operation layer for customers, making the touch screen the soul product of the touch and query all-in-one machine. The choice and configuration of the touch screen in principle and quality directly determines the overall life, stability, purchase cost and maintenance cost of the touch query all-in-one machine.
Deși există piețe de aplicații și grupuri de clienți nelimitate pentru interogarea tactilă, toate-într-un-o singură mașină, caracteristicile aplicațiilor sale au toate următoarele două categorii:
1. Populația de utilizatori nu este fixă.
The user population is not fixed, and is divided into the user as the known population and the user as the unknown population.
Known groups of people, such as placed in the halls of functional departments, are only for inquiries by customers with this type of demand. The lobby is clean and tidy, and the annex has security services. Devices that belong to a known group of people and are protected, such as taxation bureaus, post and telecommunications bureaus, police stations, bank halls and other environments. The people entering the hall and contacting the equipment are basically fixed. The equipment will not be affected by sharp objects, dust, splashing water, etc., and the equipment is used in a protected state.
Unknown groups of people, such as places where people are not fixed, such as airports, shopping malls, stations, etc., where the crowd cannot be controlled and supervised. For other outdoor and semi-outdoor equipment, although the users are basically fixed, the people who can access the equipment are completely unknown. The equipment may be damaged by scratching, splashing water, external force, dust accumulation, etc.
2 Mediul de aplicare al echipamentului este împărțit în tip de protecție interioară, tip interior neprotejat, tip semi-exterior și tip exterior.
Indoor protection type, the equipment entering the room and the people who can access the equipment are fixed, and the equipment is within the sight management of the security staff. The equipment will not be affected by sharp objects, external damage, dust accumulation, water splashing, etc. The equipment is used in a protected state.
Indoor unprotected type, such as placed in indoor environments such as airports, shopping malls, and stations. The people who enter the room to use and access the equipment are completely unfixed, and the equipment cannot be used under the supervision of security or staff. The equipment may be scratched by sharp objects, damaged by external forces, dust accumulation, and splashing water.
Semi-outdoor and outdoor types, such as semi-outdoor information halls, touch telephone halls, fully outdoor ATM machines, information service machines, etc. on the streets and downtown. The equipment is completely exposed to various users and may suffer various external damages; the equipment may undergo environmental changes such as wind, sun, rain, snow, etc., and cannot be controlled and supervised at all.
În conformitate cu caracteristicile de clasificare ale interogării tactile toate-într-un-o singură mașină, pentru diferite aplicații de clasificare, pot fi selectate ecrane tactile cu diferite principii tehnice.
A, tip de protecție interioară a populației cunoscute
Since there are no environmental impact issues such as malicious scratching, external damage, dust accumulation, and water splashing in the indoor protection application places of known people, it is judged from the application field alone, almost all the original touch technology: capacitive sensing Products of technology, four-wire resistance technology, five-wire resistance technology, surface acoustic wave technology and infrared scanning technology can all be used.
However, considering the overall performance, service life, and maintenance cost of the product, the four-wire resistance product has the characteristics of short life (less than 3 million touches), and has not been adopted by customers in the touch query all-in-one machine. Only customers who are too concerned about cost considerations and do not care about service life and maintenance costs can choose in small batches.
B, tip interior neprotejat pentru persoane necunoscute
The indoor unprotected touch query kiosks used by unknown people account for a very large proportion of the market applications. For example, we often use stations, airports, exhibition halls, and query places with complex crowd composition. The touch query kiosks are maliciously scratched. Seriously, there is pollution from dust, soot, etc., and there are hidden dangers such as being spilled by drinks. In more serious cases, there may be external impact. Therefore, the selection of touch screens is more demanding than the requirements of category A. In this kind of application, the product choices are the riot-proof capacitive touch screen, infrared touch screen, five-proof sonic screen, capacitive touch screen, riot sonic touch screen and standard surface acoustic wave screen.
C, tipuri semi-în aer liber și în aer liber de persoane necunoscute
In the semi-outdoor and outdoor market applications used by the known crowd, such as ATM machines, automatic bank service terminals, and confidence halls in the streets, the requirements for touch screens are particularly demanding due to various harsh environments and hidden dangers of malicious use and destruction. . The touch screen must be waterproof, dust-proof, anti-riot, anti-pollution, etc., to ensure the normal operation of the touch device. In such applications, touch screens are selected in order of vandal-proof capacitive touch screens, infrared touch screens, five-proof acoustic wave screens, and capacitive touch screens.
At present, when materials technology and touch technology have not developed new products, different application places and different application groups are the most favorable basis for which touch technology products to use. Therefore, the application and selection of products are based on the customer's use environment. , Application requirements have the most direct relationship.
