Heterogeneous hot standby system and method for filling and launching liquid rocket

The embodiment of the invention provides a liquid rocket filling and launching heterogeneous hot standby system and method. The heterogeneous hot standby system comprises filling controlled equipment, rocket controlled equipment, a ground filling system, a test launch control system, a remote measuring system and a network switch. The three systems are respectively connected with a network switch to form a heterogeneous distributed metadata control network; the ground filling system is connected with the filling controlled equipment through a control bus and collects sensing data in the filling process of the liquid rocket in real time; the test launch control system is connected with controlled equipment on the rocket through a control bus and collects sensing data in the launch process of the liquid rocket in real time, and the remote measurement system collects and displays sensing data in the flight process of the liquid rocket in real time through a network switch. According to the embodiment of the inve
