Portable data recorder for engineering supervision

Abstract

The portable data recorder comprises a recorder body, a mainboard and a wiring board, a protection plate is installed on the outer side of the recorder body, a fixing cylinder, a first spring and a base are installed at the bottom end of the recorder body, a fixing base is installed in the middle of the bottom end of the recorder body, and a suction cup is installed at the bottom end of the fixingbase; filter screens are arranged on the left and right sides of the recorder body; fans are mounted on the outer sides of the filter screens; a supporting column is installed at the bottom end of aninner side of the recorder body, a second spring is installed at the upper end of the supporting column, a cylinder is installed on the outer side of the second spring, and a main board is installedat the top end of the cylinder; a wiring board is installed on the rear side of the recorder body, a rotating shaft is installed outside the wiring board, a cover plate is installed outside the rotating shaft, a magnet is installed inside the bottom end of the cover plate, a limiting groove is formed in the outer side surface of the wiring board, and an iron sheet is installed inside the limitinggroove. The data recorder is reasonable in structure and simple to operate, data can be conveniently recorded, the data recorder is convenient to carry and place, and the working efficiency of data recording is effectively improved.

Description

technical field [0001] The invention relates to the technical field of data recorders, in particular to a portable data recorder for engineering supervision. Background technique [0002] The data logger can simultaneously measure temperature and humidity with one zero channel, analog voltage. Through the large color screen, it is easier for customers to clearly see the captured data and easily set parameters to observe waveforms and data during testing. Captured data can be reproduced more easily by function, and can be saved to the instrument internal memory or external USB memory. When the existing staff place the data recorder, it is easy to cause the data recorder to be unstable, resulting in large errors in data recording; the data recorder is easily subject to vibration during the handling process, resulting in damage to the parts inside the data recorder. As a result, the data logger cannot work normally, the anti-collision effect of the data logger is poor, and it...

AI Technical Summary

Problems solved by technology

When the existing staff place the data recorder, it is easy to cause the data recorder to be unstable, resulting in large errors in data recording; the data recorder is easily subject to vibration during the handling process, resulting in damage to the parts inside the data recorder. As a result, the data logger cannot work normally, the anti-collision effect of the data logger is poor, and it is easy to cause damage to the data logger. When the logger is idle, the external interface is exposed in the air, so that dust and impurities from the outside can easily enter the logger. When the staff is reading the data of the recorder, it is easy to have poor contact due to the obstruction of dust and impurities, and it is difficult to read the data, which affects the data reading work of the staff; the temperature of the data recorder is high during the working process, May cause damage to the data logger and affect data recording efficiency
