Problems solved by technology

[0003] At present, there are few test instruments used on parachutes. The existing instruments have short data collection time and the keys are easily damaged.
Airdrop standby time is too long, it is easy to fill up the storage space of the instrument, resulting in failure to collect valid data
The button switch is damaged during the airdrop, which will also lead to the failure of normal collection

Embodiment Construction

[0012] The present invention is an air pressure collection and storage system based on the STM32 microprocessor platform, which realizes large-capacity data collection, and uses a membrane switch to realize the soft start operation of the buttons; uses the MS5803-01BA digital air pressure sensor to accurately sense the umbrella system during the descent process. The air pressure changes, the relationship between the altitude and time and the relationship between the descending speed and time are obtained.

[0013] The present invention mainly uses the SDIO interface to expand the function of the SD card, so that the data storage capacity is larger and the storage speed is faster. Transplant the FATFS file system and write record data in the form of files. Data can be obtained in a manner similar to a USB flash drive, simplifying the way the computer obtains data. The membrane switch is selected, and the one-button software switch is adopted to replace the mechanical opening a...

Abstract

The invention discloses a barograph. The barograph is an air pressure collection and storage system based on an STM32 microprocessor platform, realizes high-capacity data collection, and adopts a thin film switch to realize soft start operation of keys; and adopts an MS5803-01BA digital baroceptor to precisely sense air pressure change in a parachute system falling process, thereby obtaining a relation between altitude and time and a relation between falling speed and time.

Description

technical field [0001] The invention relates to a parachute for airborne use, and the field of airdrop of a reloading system and an umbrella system, in particular to a barometric pressure recorder. Background technique [0002] At present, the air pressure sensor has been widely used in mobile terminals, and the altitude can be accurately known through the air pressure data measured by the air pressure sensor. In addition, you can also make a weather forecast to predict the weather changes in the next few days. However, air pressure sensors are seldom used on parachutes. Utilizing air pressure sensors can not only measure the altitude, but also calculate the descent speed and time. [0003] At present, there are few test instruments used on parachutes, and the existing instruments have short data collection time, and keys are easily damaged. If the airdrop standby time is too long, it is easy to fill up the storage space of the instrument, resulting in the inability to col...
