Smart terminal capacitive touch screen in power system solutions - Database & Sql Blog Articles

Smart terminal capacitive touch screens are not new in power system solutions for touch screens. Long before the arrival of this wave of smart phones, you have seen touch screens on various handheld computers, mobile phones, and even black and white screen mobile phones. But in most people's impressions, the touch screen of that era always appeared with the touch pen—you have to press the hard object of the pen or nail to achieve the input command, which is essentially a “resistive touch screen”. . Until the emergence of the iPhone in 2007, another touch screen, "capacitive touch screen" began to appear in people's sight. However, after 4-5 years of development, the touch-type intelligent terminal market has already turned into a capacitive touch screen from a resistive touch screen.
As capacitive touch screens become larger and larger, the use of writing devices like paper and pen becomes more intuitive and convenient. The most common way for manufacturers to support the stylus function is to use an active stylus or a passive stylus. Active styluses use electronic components that require a power source and transmit signals to the host device. The active stylus can support advanced features such as hovering, pressure sensing, button support, and erasing on the display. The passive stylus uses a conductive material that is equivalent to the extension of the user's body. The capacitive coupling of the user's hand supports the transmission of signals when the passive stylus touches the screen, and there is no active communication between the stylus and the host platform, so how to distinguish between the finger and the passive stylus is a problem.
Capacitive touch screen capacitive touch screens are classified into two types: Surface Capacitive Technology and Projected Capacitive Technology.
The “surface capacitive touch screen” uses only a single layer of ITO, and the electrodes are plated with narrow electrodes on the four sides of the touch screen to form a low voltage alternating electric field in the conductive body. Compared with the resistive type, the biggest feature of the capacitive type is that it does not need to be pressed, and only needs to be touched to input an instruction.
As for the "projected capacitive touch screen", it can penetrate a thicker cover layer and does not require correction. Projection capacitors can be used for the iPhone's iconic "multi-touch" operation.
Advantages: only touch, no pressure is required to generate the signal; only one or no correction is required after production; the life will be longer because the components in the capacitive touch screen do not require any movement.
Disadvantages: The cost is relatively high, but with the current mainstream smartphones choosing a capacitive screen, the scale is exploding and the cost is decreasing.
With the continuous development of the power company's business, in terms of customer service, business promotion, business inquiry, business processing, and electricity fee inquiry are all handled manually. The business processing time is long and the efficiency is low, which is difficult to adapt to the needs of user development. In order to better do the external window service work of the power supply business hall, improve the efficiency of the external window service, so that users can easily grasp the relevant process and related information, and enhance the transparency of affairs. Jin Kaixiang introduced the construction of multimedia touch screen information inquiry system into the power enterprise, which provided a close communication bridge between users and power companies.
The use of "multimedia touch screen information inquiry system" can improve the service level and service quality of the power company, optimize the service environment, provide convenience for the service object, and relatively reduce the labor intensity of the staff; at the same time, the production of a large amount of digital information can make electricity The company's information exchange easily embarks on the path of networking, internationalization and standardization, which is conducive to raising awareness and establishing a modern image. In addition, the new media of the multimedia system can also be used to promote the information dissemination of the power enterprise image, giving people a refreshing impression. The system startup and shutdown system is easy to operate, without the user's excessive intervention, the system itself loads and runs, or exits and shuts down the operating system to improve the security and stability of the system.
Power company touch screen query system features include: company profile, electricity price and payment, electricity guide, electricity business roaming, latest developments, power regulations, user electricity bills, report progress, personnel agencies, charging standards, electricity common sense.
The functions of the multimedia touch screen information inquiry system specifically include the following:
1. Introduce the performance, operation, power supply and future development plan of the power company in recent years;
2. The service organization chart of the power company;
3. Distribution map of the operating network of the power company;
4. An incremental column chart of the power supply capacity and per capita power generation of the power company.
5. Electricity price information table: Provide the electricity price price list. After selecting a user category, the definition of the user in the category and the detailed description of the charging standard can be given.
6. How to pay the electricity fee: Explain the procedures for automatic payment and manual payment. As a window for the power company to face the public, its query system has the following characteristics:
1. The multimedia inquiry system integrates the functions of power company introduction, business promotion, business inquiry, business processing, electricity fee inquiry, information announcement function, etc. The public can understand any information released by the Construction Bureau with the touch of the hand; Supervision, reflecting the image of the power company serving the people; reducing the number of grassroots office staff to repeatedly explain the business process and answer the results of the service, improve service quality.
2, multimedia query system interface is friendly, beautiful, easy to operate: no complicated operation, no dazzling menu, users can easily find the required information by simply touching the corresponding icon on the screen.
3. The software and hardware of the multimedia query system adopt modular design, which can flexibly increase or decrease the function blocks according to the needs of users. In terms of hardware, functional components such as magnetic card readers can be added, and software can flexibly add functional modules according to user requirements, so that the system can have good scalability.
3. The multimedia inquiry system, as a subsystem of the entire power integrated service system, fully considers the connection with the entire power MIS system, realizes the unification with the power consumption system, so that the user can know the required electricity fee in a timely and convenient manner. information.
4, the use of query interface and maintenance interface separate way: not only consider the professional application of system administrators, but also through multimedia means to guide non-professionals who have no computer application foundation to be able to operate the query interface skillfully, making the system safe and stable; When the data and data need to be modified, the computer-based grassroots personnel can complete it, and there is no need to configure a dedicated maintainer for each terminal.
