The core technology is the country's most important device. In recent years, the country has attached great importance to independent innovation of core technologies and products. The realization of key technologies in key areas "domestic, independent, safe and controllable" has been elevated to the strategic height of national security development. At present, under the situation of frequent international disputes and industrial control security incidents, independent innovation and localization development is imperative. The demand for localization of core controllers in the rail transportation industry will become more and more obvious. In response to the national call for localization and the strategy of "independent, safe and controllable", Qingdao Metro Group Co., Ltd. and Nanda Automation Technology Jiangsu Co., Ltd. took the lead in carrying out research on the application of domestic large-scale PLCs in the BAS control system of the metro. To lay a solid foundation for the localization and autonomy of the key equipment of the metro BAS control system. From March 20, 2019 to July 03, 2019, Nanda Automation’s domestic PLC was connected to the BAS system of Aoshanwan Station of Qingdao Metro Line 11. The system has been running smoothly for more than 3 months. The smooth implementation of the operation of the grid connection has effectively verified that the stability and reliability of the domestic PLC of Nanda Automation meet the operational requirements of the subway BAS system. It has broken the monopoly of key industrial control equipment of foreign brands in the field of urban rail transit, and has made active exploration for the development of core products of "independent, safe and controllable", which has a milestone significance.

Wang Biao, deputy secretary-general of China Urban Rail Transit Association, pointed out in his concluding speech: "As the first domestically applied Nantong AoTuo NA series PLC with a complete set of independent intellectual property rights applied to the subway environmental control system, it has broken the core technical barriers of foreign countries in one fell swoop. This system fills the gap in the domestic high-end controller market for the BAS system of the subway, and contributes to promoting the independence of China's rail transit core technology. Qingdao Metro Group, as the lead unit for project implementation, has the responsibility, sentiment, and vision to be commended. !".

The representatives of Nanda Automation Technology Jiangsu Co., Ltd. said at the meeting: "Ten years of sharpening swords, bright swords now." As a leading enterprise in the domestic PLC industry, Nanda Automation Technology's high, medium, and low series PLCs have been widely used in many fields such as petroleum and petrochemical, power industry, municipal facilities, and military industry, and users have responded well. The ice-breaking subway BAS system will provide an overall environmental control system technical solution with strong autonomy, advanced technology, and excellent cost performance for my country's urban rail transportation industry. The system promotes orderly and benign competition in the domestic subway industry, further improves the localization rate, reduces construction costs and improves service levels. Nanda Automation Technology Jiangsu Co., Ltd. will continue to increase R&D investment, continuously improve the level of technical services, and do its utmost to accelerate the process of "domestic, independent and controllable".
