Wireless posture/impact measurement recording system

Abstract

The invention relates to a wireless posture / impact measurement recording system. The system is mainly composed of a measuring module, a controller module and a power module, wherein the measuring module adopts a three-axis high gMEMS accelerometer ADXL330 and three uniaxial high gMEMS accelerometers ADXL50 to measure the posture of a carrier and the impact borne by the carrier, the controller module adopts a single-chip microcomputer CC2430 to process the data output by an information acquisition module, save the data in a storer, and then send the data to a management system through a Zigbee radio frequency transceiver.

Description

Technical field [0001] The invention relates to a wireless attitude / shock measurement and recording system, especially a wireless attitude / shock measurement and recording system whose measurement module includes a three-axis high-gMEMS accelerometer, a three-axis low-gMEMS accelerometer and a temperature sensor. Background technique [0002] At present, the shock recorders commonly used in China are mechanical shock recorders, whose internal structure is very similar to an old-fashioned typewriter, with a tape reel. It’s just that the mechanical impact recorder has two paper tape reels, the upper and the lower. Put the recording paper tape into the upper paper reel, and insert the beginning of the paper tape into the lower paper reel. There is a metal beam on which the recording pen is fixed on the top of the paper tape. Three recording pens are installed on the beam to record the impact of the carrier in the directions of X, Y, and Z axes respectively. [0003] The main di...

Problems solved by technology

[0004] (1) The length of recording paper is limited, and the recorded impact data is also limited. There is no date mark, only time coordinates

[0005] (2) The recorded impact range is only ±5g, which cannot meet the higher requirements

[0006] (3) In order to meet the requirements of 3D detection, it is necessary to install three sets at the same time, and it is inconvenient to install and read

[0007] (4) Use pressure-sensitive recording paper, which is rarely available in China, and the recording paper often jams and gets damp in humid seasons or areas and other phenomena, resulting in the loss of recorded data

[0008] (5) It is bulky and heavy, takes up a certain amount of space, cannot be carried around, and the transmission data is transmitted by wire

[0009] (6) During the transportation process, due to different transportation methods, such as ocean transportation, it will shake and shake frequently, and sometimes railway or road transportation may be required

As a result, when arriving at the installation destination, because the recording paper was not long enough, the recording paper was used up before it was transported to the installation site, which not only caused economic losses, but also the recorded data was incomplete.
