Joint control system and method for firefighting devices

Abstract

The invention discloses a joint control system and method for firefighting devices. The joint control system comprises a premixed foam firefighting assembly, a mixed foam firefighting assembly, a spray head and a controller; the premix foam firefighting assembly comprises a synthetic foam tank and a driving part, and an outlet of the synthetic foam tank communicates with an inlet of the spray headthrough a first pipeline; the mixed foam firefighting assembly comprises a water firefighting pipe network, a water pump, a foam raw liquid tank and a foam pump, an outlet of the water firefighting pipe network communicates with an inlet of the water pump through a second pipeline, and an outlet of the water pump communicates with the first pipeline through a third pipeline; a first pressure sensor, a normally opened valve and a partition valve are sequentially arranged on the first pipeline according to the flowing direction; a second pressure sensor and a first electric valve are sequentially arranged on the second pipeline according to the flowing direction; and a third pressure sensor, a second electric valve and a normally closed valve are sequentially arranged on the third pipelineaccording to the flowing direction. According to the joint control system and method for the firefighting devices, the valves can be switched in time, the mixed foam firefighting assembly is automatically started, and the fire disposal speed is increased.

Description

technical field [0001] The invention relates to the technical field of fire safety in UHV substations / converter stations, in particular to a joint control system and method for fire protection devices. Background technique [0002] UHV substations\converter stations mostly use PWZ / SP synthetic foam spray fire extinguishing equipment (ie premixed foam) as fire prevention and control equipment. In order to strengthen the continuous spraying time of foam, the pre-mixed foam fire-fighting equipment is introduced on the basis of the pre-mixed foam fire-fighting equipment, so as to improve the fire-fighting ability of the UHV substation\converter station. However, the pre-mixed foam fire-fighting equipment and the ready-mixed foam fire-fighting equipment in the prior art are independent of each other, so that the two sets of equipment cannot realize automatic joint control, and can only be manually operated step by step by the operator. In the case of a sudden fire, the operator ...
