Problems solved by technology
[0002] The existing launch vehicle power filling system can only display the gas source pressure of the gas distribution platform in the filling warehouse, the pressure of the propellant tank, and the pressure of the gas cylinder through the meter head, and the back-end interpretation hall cannot grasp the front-end in real time. The data of the power filling system is difficult to link the front and rear ends
In addition, because most of the existing signal acquisition equipment is special-purpose equipment, which is only designed for a specific test unit and a specific type of rocket, the general performance is poor, and the multiple meters in the front-end warehouse are difficult to centrally manage, and the cost is high

The invention provides a device for detecting the signal of the rocket power filling system. In order to solve the problem that there are many heads in the filling warehouse of the shooting range, the data of the front and rear ends of the filling system cannot be linked in real time, and the versatility of each model is not strong. Provide a general-purpose rocket power filling system signal acquisition device based on RS485. By using the present invention, the front-end warehouse meters can be concentrated in one combination, and the purpose of broadcasting and sharing the front-end and back-end data in real time can be assembled on different types of rockets. power filling system. Using the present invention can satisfy the power filling system signal acquisition function of different test sites between different models, carry out front-end detection on the entire filling process of the rocket power system, and transmit the data to the back end for real-time interpretation through RS485 bus technology. When there is a fault in the filling process, it is discovered in time to ensure that the system commander can grasp the filling dynamics in real time, and grasp the display information of the power system range test and propellant filling.
Description
technical field [0001] The invention relates to a device for detecting signals of a rocket power filling system. Background technique [0002] The existing launch vehicle power filling system can only display the gas source pressure of the gas distribution platform in the filling warehouse, the pressure of the propellant tank, and the pressure of the gas cylinder through the meter head, and the back-end interpretation hall cannot grasp the front-end in real time. The data of the power filling system is difficult to link the front and rear ends. In addition, because most of the existing signal acquisition equipment is special-purpose equipment, which is only designed for a specific test unit and a specific type of rocket, the general performance is poor, and the multiple meters in the front-end warehouse are difficult to centrally manage and the cost is high. Contents of the invention [0003] The object of the present invention is to provide a device for detecting signals...
