1. System overview
With the development of science and technology, the improvement of living standards and the acceleration of the pace of modern cities, people are increasingly pursuing more convenient, more practical and faster ways in work and life. All kinds of smart cards appearing around people are replacing some traditional cash, keys, tickets, paper cards, etc. The appearance of these smart cards has indeed greatly facilitated people’s work and life. As a modern intelligent office building, community, and enterprise, smart cards with complete functions, convenient use and good security are needed to cooperate with the realization of overall intelligence.
The emergence of various cards depends on the development of modern information recognition technology. Since the birth of barcode recognition technology, magnetic stripe read-write technology, contact IC card read-write technology, photoelectric technology read-write technology, etc. have appeared successively, and corresponding card types have also appeared. However, they have more or less insurmountable limitations. They cannot realize all-in-one card management and fail to achieve the effect of safety, convenience, speed, comfort and intelligence. In recent years, the proximity card IC card all-in-one card technology and RFID electronic tags can effectively solve these problems. Proximity card IC card and RFID card, with its unique contactless card mode, unique adaptability to harsh environments, large capacity for reading and writing, excellent electrical and mechanical characteristics, and extremely high security, are favored by users from all walks of life .
Proximity card IC card all-in-one card technology is widely used in various fields of society, and it is no exception in the field of intelligent buildings. In recent years, through the development and application of all-in-one card technology and the practice of intelligent construction engineering, our company deeply feels that the application of all-in-one card technology has a strong role in promoting the intelligentization of buildings, buildings, communities, enterprises, schools, and hotels. This technology expands the application scope of intelligent system integration and enhances the overall functions of the entire building. It can not only realize the information exchange, sharing and unified management between the various sub-systems of the one-card system, but also realize the various functions of the one-card system and the building. Information exchange between subsystems, unified management and linkage control.
2. Design principle
This solution will use the non-contact cards (IC& and RFID cards) that have mature applications today. The non-contact card is a card that can read and write information without physical contact. The sensing distance is 5~10CM and 2~15m. Compared with other media, it has a long service life, low maintenance cost, convenient use, safe and reliable. At the same time, we will make full use of his multi-purpose resources to use one card to complete access control, attendance, dining, and patrol functions, so as to simplify and optimize the entire system management.
In terms of controllers, we will combine the company’s existing superior network resources and adopt the latest RZ network series controllers. It adopts advanced network technology and directly uses the company network as the communication platform. This not only greatly reduces the amount of construction wiring, but also greatly improves the efficiency of data processing and transmission, and the entire system can be used across regions through the Internet. Realize resource sharing between companies. From a technical point of view, with the rapid development and wide application of network technology, this all-in-one card system based on the network has a longer technical life than other products.
Through the use of the entire system, we will see that access control can save security personnel, attendance can save management personnel, consumption can reduce financial personnel, etc., which will bring direct economic benefits. I believe that through our efforts, this “all-in-one card” system based on the network will bring your enterprise and institution management to a new level.
The smart residential community management card design scheme uses non-contact smart card technology as the management system for residents to realize the integration of residential community property management. One card can be used for multiple purposes, and it has strong confidentiality. The reader adopts mega-band and magnetic induction technology, reads the card wirelessly and adopts half-duplex communication.

3.4. Water meter system

3.4.1. Realize the mode of paying the fee before using it.
For water supply, gas, electricity and other departments, it is possible to realize the mode of paying the fee before using it. This is an advantage that everyone generally recognizes. This will help solve the problem of arrears, which was difficult to solve in the past. The water supply, gas, and electricity departments not only solved the old problem of arrears in payment, but also received funds in advance. For users, since usage fees account for a small proportion of total expenditures, this change, for users, only advances the delivery time of fees for a period of time, so users are not sensitive. But for the water supply, gas, electricity and other departments, this change cannot be underestimated. With the shortage of water, electricity, gas and other resources and the gradual recognition of their commodity attributes by the society, their transactions will gradually adopt the trading mode of general commodities. Obviously, paying fees before using them is a more reasonable trading mode. .
3.4.2 The mode of charging for meter operation has been changed.
The significance of this model change is huge. Due to the continuous expansion of the scale of the city and the rapid increase in the number of residents, the workload of meter reading and charging of various departments will continue to increase. It will be difficult to adapt to this change if the traditional door-to-door meter reading mode is used. However, due to various reasons, the efficiency of manual meter operation has gradually decreased and the cost of this model has been increasing. There are many ways to solve this problem, but relying on technological progress to solve this problem should be a more advocating way. Obviously, the adoption of the IC card meter and management system will fundamentally change the mode of charging for meter reading by various departments sent to thousands of households. As long as each department sets up a reasonable fee payment agency, it will basically not cause trouble to users. If you get the cooperation of the financial system, you can also reduce the cost of deployment.
Therefore, the large-scale adoption of IC card meter technology will significantly help reduce the management costs for various departments. With the use of IC cards for transaction settlement, users can independently determine the time and amount of payment, which increases the autonomy of users. Especially with the enhancement of people’s awareness of family security and privacy, random access to private households, such as meter reading and door-to-door charging, will gradually become unpopular or even resisted. This is a social development trend that must be paid attention to. The use of IC cards for transaction settlement will effectively solve this problem that will bring many social risks.
3.4.3. Some technical problems can be solved effectively. For example, with the shortage of various resources, more complicated usage management models such as over-plan prices and even stepped prices will be gradually implemented. These will put forward higher technical requirements for supply transactions. It is difficult to solve these technical problems with the mode of ordinary meter and manual meter reading, and the use of IC card will easily solve these problems.
3.4.4. With the development of science and technology, the supply industry also needs to gradually realize the use of high-tech means to manage water supply and power supply. Using traditional watches, this leap is difficult to complete, and the use of IC cards will lay a technical foundation for the use of computer technology for modern management.
3.4.5. Of course, the use of IC cards has other advantages, for example, it can effectively solve the problems of measurement wrangling, use disputes, corruption costs, favor fees, and difficulty in using statistics.
3.4.6 Compared with the remote meter reading system, IC card meters have very low use and maintenance costs, and there are no problems such as confusion and high failure rate caused by wiring.
