[0016] The downhole information acquisition device based on STM32 can detect environmental pressure, temperature and position information through the pressure detection module, temperature detection module and position detection module, realize effective data processing through the STM32 core processor, and save the detected data through the data storage module to provide data support for later analysis, wherein the above information can be collected in real time or according to preset time intervals or event trigger conditions.

[0017] Wherein, the STM32 core processor 1 can use the high-performance, low-power STM32L series microcontroller as the control center of the whole system, responsible for coordinating the work of each module;

[0018] The pressure detection module 2 can use a silicon piezoresistive pressure sensor, which is connected to the STM32 core processor via an RS-485 interface to accurately detect the ambient pressure;

[0019] The temperature detection module 3 can adopt a digital temperature sensor (such as DS18B20), which is connected to the STM32 core processor through a single bus interface and directly outputs a digital temperature signal, thereby simplifying the subsequent processing flow;

[0020] The position detection module 4 can adopt the ultrasonic ranging module HC-SR04, which adopts the echo ranging principle, determines the distance by the time difference between the trigger pin sending out the ultrasonic wave and receiving the reflected wave, is directly connected to the GPIO pin of the STM32 core processor, and uses the timer to calculate the time interval;

[0021] The data storage module 5 can use a non-volatile storage medium, such as an SD card or EEPROM, which can keep data from being lost even in a power outage, ensuring the safe storage of important data. The data storage module is connected to the GPIO interface of the STM32 core processor through the SPI technology.

Preferably, the speed detection module adopts a Hall effect sensor, which is directly connected to the GPIO interface of the STM32 core processor, and the speed is calculated by the STM32 through an interrupt service program.

[0025] As an improvement of the technical solution, the shell is a split connection structure and a sealed cavity is formed in the middle. Preferably, the shell includes an upper shell and a lower shell that are threadedly connected and are equipped with a rubber sealing ring to achieve waterproof sealing. The shell is preferably made of steel material with good protective performance to ensure that the equipment can work normally even in harsh environments.
