Embodiment 1

[0052] Please refer to figure 1 , a rocket data acquisition and transmission system provided in this embodiment includes:

[0053] Sensor 1, there are several sensors 1, and they are distributed in each cabin 10 of the rocket, and are used to collect non-electrical parameters;

[0054] The sensor acquisition device 2 is arranged in part of the rocket cabin 10 and used to receive the non-electrical parameters collected by the sensor 1 in the cabin 10;

[0055] The data acquisition and editor 3 is used to receive the non-electrical parameters and send them to the modulation transmitting equipment after AD conversion; The non-electrical parameters of the rocket cabin 10 of the acquisition device 2 are directly sent by the sensor 1 in the cabin 10 .

[0056] Because the sensors 1 are distributed in different cabins 10 of the spacecraft, and are unevenly distributed in each cabin 10 . Therefore, the sensor collection device 2 can be installed in the cabin 10 where the sensors 1 ...

Embodiment 2

[0089] like Figure 4 As shown in , the present embodiment provides a rocket data acquisition and transmission method, based on the rocket data acquisition and transmission system of Embodiment 1, the configuration of the data acquisition and editor 3 includes the following steps:

[0090] S10: the collection frequency f is set at the first setting 1 Collect non-electrical parameters from sensor acquisition device 2 or sensor 1; the non-electrical parameters corresponding to each sensor 1 have a corresponding first set collection frequency f 1 ;

[0091] S20: Store the non-electrical parameters detected by each sensor 1 into the data storage bit corresponding to the sensor 1; the non-electrical parameters corresponding to each sensor 1 in each data frame are set with f 1 / f storage bits, and the storage bits corresponding to the same sensor 1 are evenly distributed in the data frame;

[0092] S30: Send the data frame to the modulation transmitting device at the first sendin...

Abstract

The present application discloses a rocket data acquisition and transmission system and a rocket data acquisition and transmission method, wherein the system includes: sensors, there are several sensors, and the sensors are distributed in each cabin of the rocket for collecting non-electrical parameters; sensor acquisition equipment, arranged in Part of the rocket cabin is used to receive non-electrical parameters collected by sensors in the cabin; data acquisition and editor is used to receive non-electrical parameters and send them to the modulation launch equipment after AD conversion; rocket cabin with sensor acquisition equipment The non-electrical parameters of the rocket cabin are sent by the sensor acquisition device, and the non-electrical parameters of the rocket cabin without sensor acquisition equipment are directly sent by the sensors in the cabin. The rocket data acquisition and transmission system and the rocket data acquisition and transmission method are beneficial to reduce the carrying load of the spacecraft.

Description

technical field [0001] The present application generally relates to the technical field of aerospace equipment, and in particular, to a rocket data acquisition and transmission system and a rocket data acquisition and transmission method. Background technique [0002] With the vigorous development of commercial aerospace, people are designing more and more new types of engines, control equipment and other aerospace equipment. New aerospace equipment needs to be carried on the spacecraft for flight test. In the process of spacecraft flight test, the collection and transmission of relevant data is particularly critical, which is an important basis for reflecting flight test results and guiding subsequent improvements. The sensors used to collect non-electrical parameters in the spacecraft are numerous and distributed in different cabins. The collected data needs to be uniformly transmitted to the data acquisition and editor, which is converted into digital signals by the data ...
