Description

Technical Field

[0001] This application relates to the field of wireless signal isolation technology, and specifically, to a micro portable data recording device and system. Background Art

[0002] The background art of micro data recorders usually stems from the need for data acquisition, storage, and transmission in complex environments, especially in fields such as industry, scientific research, transportation, and military. These devices are used to monitor and record various physical quantities (such as temperature, humidity, pressure, acceleration, etc.), and save the data for subsequent analysis or real-time transmission.

[0003] Traditional data recording devices are usually bulky and large in size, which limits their use in small spaces or mobile scenarios. At the same time, these devices may lack the ability to resist vibration and harsh environments, and it is difficult to maintain data accuracy and device stability under harsh environmental conditions. In order to improve the adaptability of data recorders under extreme conditions, the need for miniaturized and lightweight devices has emerged.

[0004] In many scenarios, data recording devices need to operate stably for a long time in high-vibration, high-temperature, humid, and even corrosive environments. These environments pose higher requirements on the physical structure and anti-interference ability of the devices. Especially in industrial and military applications, the devices not only need to withstand physical impacts, but also need to ensure high-precision and integrity of data.

[0005] With the progress of modern technology, the demand for data acquisition and recording has expanded from fixed devices to portable devices. Such portable devices need to integrate multiple functional modules (such as sensors, data processors, memories, etc.) in a smaller volume, and have the characteristic of low power consumption, so as to be able to work continuously for a long time without being attended.

[0006] In many application scenarios, data acquisition is not limited to a single type of physical quantity. The device may need to monitor multiple parameters simultaneously, and perform real-time processing and transmission of these data. Traditional devices are relatively limited in data processing ability and transmission rate, and it is difficult to meet the needs of modern multi-parameter synchronous monitoring.

[0007] With the development of communication technology, modern data recorders are required to have fast data transmission capabilities, such as remote data transmission through Ethernet ports, serial ports, etc. At the same time, the progress of data storage technology enables micro devices to integrate larger-capacity storage units, and supports long-term data storage and fast export to meet the needs of subsequent analysis and processing.

[0008] Modern micro data recorders usually adopt a modular design to be flexibly configured according to different application requirements. For example, the device can add more sensor modules through expansion interfaces to adapt to data acquisition requirements in different environments. This design enables the data recorder to be applied not only in the industrial field but also in various scenarios such as scientific research, medical treatment, and environmental monitoring.

[0009] The prior art with the patent number CN220896938U discloses a portable data recorder. The prior art discloses including a housing, one side of the housing is provided with a cover plate, and four locking mechanisms are provided at the four corners of the cover plate and the housing. The locking mechanism includes a support rod fixedly installed on the inner wall surface of the cover plate. Two limiting plates are respectively fixedly installed at both ends of the cover plate close to the support rod. A clamping block is slidably installed between the two limiting plates. A chute is provided on the outer surface of the clamping block. Two second springs are fixedly installed between one side of the clamping block and the support rod. A clamping groove is provided on the inner wall of the housing. One end of the clamping block away from the two second springs is slidably installed in the clamping groove. A leakage hole is provided on the outer surface of one side of the housing, and a cleaning mechanism for dust cleaning and collection is provided in the leakage hole.

[0010] The utility model is convenient for disassembling and assembling the cover plate and the housing through four locking mechanisms, with relatively convenient operation and improved work efficiency. The disadvantage of this prior art is that the inventive concept is limited to the ease of assembly and disassembly of the device, and no further strengthening designs are made for the size, portability, stability, and strength of the device.
