Ground long-time controllable pyrotechnic composition product

The invention discloses a ground long-time controllable pyrotechnic composition product which comprises a secondary power source, a controller, a plurality of pyrotechnic heat sources and a fixing plate. And the secondary power supply, the controller and the plurality of firework heat sources are arranged on the fixed plate. And the secondary power supply is connected with the controller and is used for converting an external power supply into voltage used by the controller. The controller is respectively connected with activation lines and detection lines of the plurality of firework heat sources, and can independently activate the firework heat sources and detect whether the firework heat sources end working or not. The technology is mature and reliable, all smoke and fire heat sources are independently controlled, the ignition time is accurate, the combustion ending time can be monitored, different combination modes such as continuous combustion and simultaneous combustion of multiple smoke and fire can be
