Smoke discharge device and control system in high rise

The invention relates to a smoke discharge device and a control system in a high rise, and belongs to the field of fire fighting systems. Top smoke extractors are arranged below top floors, and connected through horizontal connecting pipes, and intermediate floors are arranged below the top smoke extractors; intermediate smoke extractors are arranged below the intermediate floors, and connected to the top smoke extractors through vertical connecting pipes, and the front end, upper end, lower end, left end and right end of a shell of the smoke extractors are provided with square openings separately; and five fan devices are provided, and installed on the five square openings of the shell of the smoke extractors separately. When smoke is detected, the control system starts processing, and an appropriate scheme is selected; the smoke is discharged from both sides and the upper and lower floors quickly, so that the discharge pressure of lots of smoke in a single floor is relieved, and the quick discharge of the s
