Rocket launching control system

The invention discloses a rocket launching control system. Specifically, a boosting power supply is connected to one end of a boosting capacitor, the other end of the boosting capacitor is grounded, and a first current limiting resistor is connected with the boosting capacitor in parallel; the boosting power supply is accessed to a CPU (Central Processing Unit) through a first analog input interface; a launching control power supply is connected to the boosting power supply through a second current limiting resistor and a double-pole and double-throw relay which is connected with a resistance measuring pathway, and a switch of the relay is connected with a firing circuit of a controlled rocket; the resistance measuring pathway is accessed to the CPU through a second analog input interface; the control end of the relay is accessed to the CPU through a DI/DO (Digital Input/Digital Output) interface; a control instruction output from outside is received by the CPU and is transmitted to the control end of a launc
