随着手机行业的快速发展，越来越多的手机具有更多更强大的功能，很多业务在使用时需要到营业厅进行办理。在办理这些业务时，为了用户信息安全和管理方便，往往需要先对用户进行身份验证才能办理。随着使用手机的人数急剧增加，办理手机业务的人数越来越多，营业厅的柜台往往无法满足大量的客户需求；而且在很多场合往往难以找到移动营业厅，因此用户无法办理业务，不仅给用户造成了极大的不方便，也增加了工作人员的工作强度。自助终端及时出现并解决了这个问题。自助终端不仅能够办理一些移动业务，而且具有打印小票的功能，而且其网络适应性强、电池供电能力强、携带方便等优点使得其一经出现便受到广泛亲睐。 With the rapid development of the mobile phone industry, more and more mobile phones have more and more powerful functions, and many services need to be handled in the business hall when using them. When handling these businesses, for the sake of user information security and convenient management, it is often necessary to authenticate the user before handling it. With the sharp increase in the number of people using mobile phones, more and more people are handling mobile phone business, the counters of business halls are often unable to meet the needs of a large number of customers; The user has caused great inconvenience, and has also increased the work intensity of the staff. The kiosk came up in a timely manner and resolved the issue. Self-service terminals can not only handle some mobile services, but also have the function of printing small tickets, and their advantages such as strong network adaptability, strong battery power supply capacity, and easy portability make them widely favored once they appear.
自助终端一般采用锂电池，充电多采用低压直流电源的锂电池充电器，一般采用专业充电IC或者实用单片机对其进行恒流恒压充电，效果好但成本高，而且充电即对主板和打印机全部充电，不能根据两部分电池的具体情况进行调节，很容易损坏电池。 Self-service terminals generally use lithium batteries, and lithium battery chargers with low-voltage DC power are often used for charging. Generally, professional charging ICs or practical single-chip microcomputers are used to charge them with constant current and constant voltage. The effect is good but the cost is high. Charging cannot be adjusted according to the specific conditions of the two parts of the battery, and it is easy to damage the battery.
对于自助终端，部分特殊的内部电路模块需要不同的直流电压，太高的电压可能会对电路造成一定的损害，太低的电压不能让功能模块正常有效的工作，这就需要一个安全可靠的电压转换电路。在电压转换过程中，若是没有一个安全可靠的电压检测电路和电压保护电路，很容易就让内部功能模块受损。 For self-service terminals, some special internal circuit modules require different DC voltages. Too high voltage may cause certain damage to the circuit, and too low voltage cannot make the functional modules work normally and effectively, which requires a safe and reliable voltage. conversion circuit. During the voltage conversion process, if there is no safe and reliable voltage detection circuit and voltage protection circuit, it is easy to damage the internal functional modules.
