Necessity of National Production of Industrial Switches

Industrial Switches are mainly used in electric power automation, factory automation, coal mine automation, rail transit, wind power and other fields, followed by metallurgy, petroleum and petrochemical, road traffic control automation, building automatic control system, oilfield control automation, hydropower station control automation, machine room monitoring system, water conservancy monitoring, environmental protection monitoring and other industrial control automatic places. The industrial switch is applied in some industrial sites with harsh environmental conditions due to its high protection level (generally IP40), strong electromagnetic compatibility (EMS4), and stable working performance, providing a strong guarantee for industrial communication.

Although the overall capacity of China's network communication system has been able to compete with international giants through years of development, and international enterprises such as Huawei, ZTE, and Fiberhome have emerged, and they have begun to dominate the domestic market, the core chips used by these enterprises in the current industrial switches still rely on foreign imports in recent years, basically using the universal switching chips of American Broadcom, and the core technology is still under the control of others. As a result, the products are not differentiated enough, and the development and supply are heavily dependent on foreign companies.

Why must we master the core technology of industrial switch to realize localization? Because only the products that we can make can the West talk about free trade with us. Otherwise, it is selling at a high price or blocking. Like ethernet switches, they have been monopolized by foreign countries before. The deflector cost us $35 a piece. It doesn't have much technical content. It's not good if we don't buy it. Later, the domestic ethernet switches made a breakthrough and the technology became mature. At this time, the price of imported switches began to plunge. The original price of 100,000 yuan has dropped to 10,000 yuan, and it is no longer arrogant. This is why we must master the core technology and realize localization. Because only we can make it ourselves, we will not be "choked" or "pulled wool".

Against this background, the Chinese government has successively launched the strategy of becoming a manufacturing power and a network power. The State Council and the Ministry of industry and information technology have separately issued the guiding opinions on deepening the development of the industrial Internet through "Internet + Advanced Manufacturing" and the industrial Internet development action plan (2018-2020). The strategy of "accelerating the formation of a large domestic cycle as the main body, and promoting both domestic and international cycles" will give full play to China's large-scale market advantages and domestic demand potential. The Regulations on the Security Protection of Key Information Infrastructure, which was formally implemented on September 1, 2021, fully reflects the strong will and determination of the central government to maintain national security, and accelerates the autonomous and controllable development process of the localization of industrial grade switches.

It has become an inevitable trend to autonomously control the national production of industrial switches and develop domestic local brands. After several years of research and development on core chips, the national production of industrial switches has been basically realized. The biggest advantage of the national industrial switch is its high cost performance and communication security. This is also in line with the market demand of the communication industry. Therefore, with the increasing demand for industrial switches in security work, it has become the mainstream to vigorously develop national industrial switches. With the development and maturity of switch technology, the national industrial switch will soon become the mainstream of communication transmission products.

With the continuous acceleration of the manufacturing power strategy, the network power strategy and the science and technology self-reliance strategy, Shenzhen Houshi Network Technology Co., Ltd. has also joined the national team of independent and controllable production, and has launched a number of independent and controllable domestic network communication equipment to the market. For the national industrial switches, Houshi always adheres to the following three principles:

Dominate the selection of national industrialization

1. The product design scheme is mainly based on Taiwan Realtek, domestic Shengke, Nanfei, Yutai and other brand chips;

2. The product form ranges from 100M, gigabit to 10M, with multiple optical ports, multiple electrical ports, and multiple management and non management feature combinations (Layer 2 and Layer 3 management routing functions are fully realized);

National production of key parts

1. All power modules are customized and developed domestically;

2. The vast majority of electronic materials can be replaced by national production;

3. The structural parts are manufactured independently in the country with the cooperation of manufacturers;

4. Packaging materials and other materials are produced independently in China, with the cooperation of manufacturers;

5. At present, the localization rate is more than 97%;

All independent intellectual property rights of software and hardware design

1. Hardware circuit design and realization of all independent intellectual property rights;

2. The software team has a full set of independent development capabilities; (including bottom driver, embedded, and network management software)

As a private enterprise with scientific and technological innovation, we focus on the field of communication equipment, and is committed to localization in the field of industrial switches. We are willing to become a witness, participant, and striver of scientific and technological innovation, and grow together with the historical process of localization. Years of accumulation and precipitation make us more and more aware of the importance and significance of comprehensive localization of industrial switch equipment, especially in special industries such as aerospace, which is a strategic need and a historical mission.
