Description

Technical Field

[0002] The purpose of setting up a signal acquisition device is as follows: to extract specific signals (such as wireless communication signals, satellite signals, sound waves, vibrations, etc.) from a complex environment for analysis, monitoring or recording. Example: Capturing WiFi signals for network security analysis, or collecting satellite signals for positioning. Data conversion and processing: Converting analog signals (such as electromagnetic waves, sounds) into digital signals for easy processing by computers or control systems. Example: The analog-to-digital converter (ADC) converts the analog voltage output by the sensor into a digital value. Support subsequent applications: Provide a data basis for scientific research experiments, industrial monitoring, medical diagnosis, environmental monitoring, etc. Example: Collecting vibration signals from equipment operation to predict faults, or recording voiceprints for biometric identification. Real-time and accuracy: Ensure the accuracy of the signal in time, frequency and amplitude to avoid distortion or noise interference.

[0003] Especially when used in outdoor or on-site environments, for field geological exploration (collecting seismic waves, electromagnetic signals), power inspection (monitoring transmission line noise or electromagnetic fields), environmental monitoring (collecting meteorological data, pollution source signals), etc., the signal acquisition device needs to be portable and quickly operational to make the device more suitable for outdoor use.

[0004] Currently, when using a portable signal acquisition device, although the acquisition device is installed inside a portable case through a simplified structure and a handle is added to the outside or bottom of the portable case for easy carrying, since the signal acquisition device is placed inside the case, when it is needed, complicated installation operations are required to make the signal acquisition device work.
