Abstract

The utility model relates to the field of signal acquisition, in particular to a signal acquisition structure with a signal shielding protection structure. The technical problem is that in the process of collecting weak signals, a conductive material is used for wrapping a signal collector to form a Faraday cage effect, so that a method for blocking external electromagnetic interference may cause certain influence on target signals, and thus the collection result may be slightly influenced. According to the technical scheme, the signal acquisition structure with the signal shielding protection structure comprises a heat dissipation assembly, a heat conduction assembly and an anti-interference assembly. By arranging the adjustable shielding device and the built-in heat dissipation system, the equipment can flexibly adjust the contact area between the signal receiving assembly and the outside, so that the acquisition effect is prevented from being influenced by insufficient target signal strength, and meanwhile, the built-in heat dissipation system can reduce the internal temperature of the equipment in real time, so that the acquisition efficiency is improved. Efficient operation in the signal acquisition process is ensured, and performance reduction caused by overheating is prevented.

Description

Technical Field

[0001] The utility model relates to the field of signal acquisition, in particular to a signal acquisition structure with a signal shielding protection structure. Background Art

[0002] Signal acquisition refers to the process of converting analog or digital signals from physical quantities into processable data using various sensors and measuring devices. These physical quantities can be temperature, pressure, sound, light intensity, electromagnetic field intensity, etc. The purpose of signal acquisition is to obtain information about the measured object for analysis, processing and decision-making. The main function of the signal shielding protection structure of the signal collector is to prevent the influence of external electromagnetic interference on the internal circuit of the signal collector and ensure the accuracy and reliability of signal acquisition. During the signal acquisition process, external electromagnetic interference may come from various sources, such as radio waves, power lines, motors, etc. These interferences may introduce noise, causing the collected signal to be distorted or important information to be lost. At present, by wrapping the signal collector with conductive materials to form a Faraday cage effect, external electromagnetic interference can be effectively blocked to prevent it from entering the interior of the device, but these materials will also cause a certain degree of blocking to the target signal. If the intensity of the target signal is weak, it may affect the acquisition results. Utility Model Content
