Microsensor capable of being embedded in movable part in cavity

Abstract

The invention discloses a microsensor capable of being embedded in a movable part in a cavity. The microsensor comprises a shell, a sensing element, a battery, an integrated chip, a front cover and arear cover. A step hole is formed in the shell. The sensing element is installed in the step hole in one side of the shell. The battery is in a half-cylinder shape. The integrated chip is encapsulatedinto the half-cylinder shape and is matched with the battery to form a cylinder. The cylinder is installed in a rear section cylinder hole of the shell and connected with the sensing element througha pin and a jack. By encapsulating an A/D conversion circuit, a write-in circuit, a storage unit, a read-out circuit and a crystal oscillation circuit on one integrated chip, the size of the sensor isreduced, and the sensor can be conveniently embedded in the movable part in the tested cavity; data can be circularly stored in the storage unit in real time in the detecting process; the data is read out and secondarily processed after detection. The problem can be effectively solved that a sensing element on the movable part cannot be connected with a data line or wireless signals are shieldedby the cavity, so data cannot be transmitted out or saved.

Description

Technical field [0001] The present invention relates to sensors in the field of detection technology, and more specifically, to a miniature sensor that can be embedded into a moving part in a cavity. Background technique [0002] It is a common structural form of mechanical systems that the enclosed cavity contains moving parts. For example, the housing of the reducer constitutes the enclosed cavity, and the gears and gear shafts are the moving parts; the housing of the pump constitutes the enclosed cavity, and the rotor and sliding vanes are among them. Moving parts: Although some structures do not have a closed cavity, the main parts are moving parts, such as the blades of aircraft engines. In the process of research and work, it is of great value and significance to obtain signals such as pressure and acceleration on moving parts online or offline. [0003] During the operation of the equipment system, the moving parts are always in motion. If a sensor is to be installed on it,...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the equipment system, the moving parts are always in motion. If a sensor is to be installed on it, the installed sensor must not have a data transmission line, resulting in the inability to collect the signal of the traditional sensor; the airtight cavity of the equipment will generally be seriously damaged. Affect the transmission quality of the wireless signal, or even be shielded, resulting in the problem that the sensing signal cannot be transmitted even if the wireless transmission module is integrated in the sensor
