[0002] The control of generator set supporting linkage equipment is a complex system, aiming to ensure the coordinated operation of the generator set and auxiliary equipment to achieve efficient, stable and safe power output. The main supporting linkage equipment of diesel generator sets includes fuel supply systems, ventilation systems, external circulation cooling water systems, smoke elimination and temperature control systems, etc.

[0003] In the prior art, each supporting equipment of the generator set is independently linked. For example, the Chinese patent CN117175500A published on December 5, 2023 is a generator set linked fire protection system, and the Chinese patent CN117189524A published on December 8, 2023 is a generator set linked heat dissipation system. Among these prior arts, there is no formation of linkage control between different supporting equipment of the generator set.

[0004] In addition, in the prior art, the linkage of the cooling circulation water system during the start and stop of the generator set is only a simple linkage start and stop. Due to changes in power demand, the start and stop of the generator set may be the start and stop of several groups of generator sets among multiple groups. At this time, if the cooling circulation water system starts and stops all in linkage, it will cause waste of resources in the cooling circulation water system. Summary of the Invention

Each generator set outputs a group of start or stop signals to the cooling water pump control box through the signal module; after the generator set starts, the cooling water pump control box determines the number of pumps to be put into operation according to the number of groups of start signals output by the generator set; after the generator set stops, the cooling water pump control box determines the number of pumps to be shut down according to the number of groups of stop signals output by the generator set; the generator set outputs start or stop signals to the ventilation system through the signal module to control the ventilation system to start ventilation or stop ventilation.

[0007] Further, the cooling circulating water system further includes an electric valve for the cooling water inlet pipe. After the generator set starts, the control box of the cooling water pump opens the corresponding electric valve for the cooling water inlet pipe according to the number of groups of start signals output by the generator set; after the generator set stops, the control box of the cooling water pump closes the corresponding electric valve for the cooling water inlet pipe according to the number of groups of stop signals output by the generator set.

[0013] Further, the number of the oil storage tanks is two or more, and a second liquid level gauge is provided in each oil storage tank; when the inlet electric valve of any daily use fuel tank is opened, first judge whether the liquid level signal of the first oil storage tank is within the available threshold range.
