Wang Lin, former deputy director of the Department of Urban Construction, Ministry of Housing and Urban-Rural Development, Wang Yi, former deputy director of the Information Center of the Ministry of Housing and Urban-Rural Development, Cao Yanjin, Director of the Water Department of the Ministry of Housing and Urban-Rural Development, and the Standards Institute of Standards and Quotas of the Ministry of Housing and Urban-Rural Development Changzhan Lei, Director of the Information Center of the Ministry of Housing Urban and Rural Construction, Qu Fushun, Director of the IC Card Application Service Center of the Ministry of Housing and Urban-Rural Development, Ma Hong, and Zhang Yonggang, Deputy Director of the National Standardization Technical Committee for Intelligent Building and Residential Digitalization, attended the meeting. A number of experts from the Supervision Bureau, the Ministry of Housing and Urban-Rural Development Information Center, Beijing Water Supply Group and other experts form a review expert committee to discuss and review the plan.

Director Zhang Linwei mentioned that the Ministry of Housing and Urban-Rural Development had done a lot of work in water construction and development and water meters in the early stage. Along with the rapid development of information technology and the need for smart city construction, it also promoted the scientificity and convenience of water management and developed intelligence. Water meter is of great significance. The smart metering scheme based on the domestic cipher algorithm researched at this conference should fully consider the existing laws and regulations, relevant standards, and the status quo of the industry development, fully demonstrate the necessity and operability, and promote the autonomous and controllable information security of the smart meter.

Director Cao Yanjin spoke of the fact that the water meter industry is a traditional industry, and with the development of a new era, it has put forward new requirements for the water meter industry. The water meter is an important part of responding to the common people's interests. The smart water meter solves the problem of meter reading, which is conducive to raising people's sense of security. Water meters are an important part of urban infrastructure. They are related to urban safety and it is of great significance to improve the level of information on water meters.

Director Zhan Lei first introduced that the water metering industry has set relevant standards and talked about the lack of support for related standards in terms of safety. Focusing on safety issues in the water meter industry, it is planned to formulate national mandatory standards. At the same time, it is required to take this smart meter safety plan as an opportunity to sort out the standard system for water meter application and strengthen the implementation of standards. For national standards that perform better, consider raising them to international standards and raising the level of international standardization and international influence. On this basis, we will carry out relevant inspection and verification work based on standards and promote the development of the market.

Compared with the electricity and gas industries, the water industry has a low degree of intelligence, and various types of water meter products are complex and the standardization level needs to be improved. Most domestic water meters still use mechanical water meters, which have many problems, such as data copying, labor costs, data accuracy, and difficulties in accessing households. Faced with the "one household, one watch" transformation and the implementation of water price ladder, smart water meter has become the development trend of the water meter industry.

The application of intelligent water meters brings higher requirements for information security of water meters while bringing convenience to enterprises and users. At present, intelligent water meters lack corresponding protection for information storage and information transmission in practical applications, in order to respond to national passwords. With the autonomous and controllable call for the algorithm and cipher product, the National Zhi Zhi Standard Committee initiated the study of the program with relevant units in September 2017. Based on the extensive investigation of the status quo of the industry, the experts were organized to conduct demonstrations and the safety of the SM4 algorithm was developed. Chip technology solutions.

The review experts listened to the â€œIntelligent water meter security technology solution based on domestic ciphers algorithmâ€ preparation team's introduction to the program's development situation and related technical content descriptions. They discussed and reviewed the plan and formed the following opinions: 1. Based on the smart city The need for information security by smart water utilities, and the need to strengthen security protection for information storage and information transmission in practical applications of smart water meters. At the same time, it is necessary to develop the program to implement national independent and controllable requirements for cryptographic algorithms and cryptographic products. Timeliness. 2. The preparation of the plan is based on relevant national and industry standards, and it is in line with the development status of smart water meters. It has practicality and operability, and fills the technical gap of intelligent water meter safety management. 3. The technical requirements, data formats, and units involved in the proposed scheme should be consistent with the industry standards.

In the end, the committee of experts agreed that the program should be reviewed, revised, and improved to carry out pilot application and popularization of related technologies.

Electric Bicycle: Revolutionizing Urban Mobility

Within the ever-evolving world of Electric Bicycles (e-bikes), several categories have emerged to cater to diverse riding styles and preferences. Here's a brief introduction to three key segments: Electric Bikes, Mountain Bikes, and BMX Bikes, highlighting the allure of Road Electric Bikes within the Electric Bikes category.

Electric Bikes:
At the forefront of sustainable transportation, Electric Bikes embody the future of urban commuting. Among them, Road Electric Bikes stand out for their seamless integration into city life. These bicycles harness the power of electricity, blending eco-friendly propulsion with sleek, aerodynamic designs. Equipped with high-capacity batteries and efficient motors, Road Electric Bikes transform even the most arduous urban journeys into effortless rides, ensuring every trip is a breeze. Whether navigating crowded streets or tackling long-distance commutes, they offer a hassle-free, eco-conscious mode of transportation that enhances your daily routine.

Mountain Bikes:
While Electric Bikes cater to the needs of urban dwellers, Mountain Bikes take e-cycling to rugged terrains. Electric Mountain Bikes combine the thrill of off-road adventures with the assistance of electric power, enabling riders to conquer steep hills, traverse rocky trails, and enjoy longer, more challenging rides without exhausting themselves. These bikes feature sturdy frames, robust suspension systems, and wide, knobby tires designed to grip any surface, making them ideal for exploring the great outdoors.

BMX Bikes:
At the other end of the spectrum, BMX Bikes represent the essence of freestyle cycling. While traditional BMX bikes are not typically electric, the concept of incorporating electric power into BMX-inspired designs hints at a future where tricks and stunts can be performed with even more ease and creativity. Electric BMX Bikes, if they exist or are envisioned, would likely prioritize lightweight construction, agile handling, and powerful motors capable of propelling riders through the air for spectacular jumps and tricks. However, the current focus of BMX culture remains centered around non-electric bikes, emphasizing skill, balance, and the thrill of pushing physical boundaries.

In conclusion, Electric Bicycles encompass a diverse range of designs and applications, from the sleek and efficient Road Electric Bikes that revolutionize urban commuting to the rugged Electric Mountain Bikes that conquer natural landscapes. While BMX Bikes may not yet fully embrace electric power, they continue to inspire innovation and excitement within the cycling community.
