[0002] In the 1970s, with the introduction of large-scale thermal power units, most domestically produced DCS control systems were imported along with the main generator sets. Major imported DCS brands included OVATION, FOXBORO, ABB, Hitachi, Siemens, and Honeywell. After 2005, with the introduction, assimilation, and absorption of foreign technologies, domestic DCS brands developed rapidly, including Guodian Zhishen, Xinhua, Hollysys, Supcon, and Nanjing Keyuan. Applications gradually expanded from peripheral systems to the main generator set, and from DCS to DEH (Digital Engine Headquarters). However, complete independent control over the CPU core hardware and operating system has not yet been achieved.

[0003] Currently, the core components of the DCS systems in thermal power plants are all based on foreign chips and operating systems. The DCS system products using imported hardware and software will result in users having no spare parts to replace when hardware is damaged, and the software system cannot be upgraded or maintained. Users of the DCS system will not be able to achieve independent control, and there will be serious hidden dangers to the safety and reliability of the power system.

[0004] Existing maintenance equipment requires maintenance personnel to carry it to the site by hand, which not only easily causes hand fatigue but also occupies the hands, making it inconvenient to operate the maintenance equipment with both hands.

[0005] Therefore, it is necessary to provide a thermal control and maintenance device for thermal power plants to solve the above-mentioned technical problems. Utility Model Content
