Transportation condition monitoring recorder based on micro-inertial component

Abstract

The invention discloses a transportation condition monitoring recorder based on micro-inertial component, comprising a controller, an accelerometer, a memorizer, a clock unit, and a serial communication interface. The microcontroller works in an intermittent manner, so that the use time of batteries are greatly prolonged; a tri-axial accelerometer and a digital temperature sensor are used as sensitive components which can record the shock vibration information and environment information of transported articles in all directions; the tri-axial accelerometer adopts a low-voltage power supply mode, has low power consumption and small volume, and can bear relatively large impact; the clock unit has an uninterrupted timing function, and can record the accurate occurring time of impact events; the memorizer is a pluggable SD (secure digital) card and provided with a Fat file system, wherein data can be led into a computer without disassembling the device. The monitoring recorder designed by the structure has the advantages of low weight, low power consumption and large storage data; and the monitoring recorder can be used in wide transportation condition monitoring.

Description

technical field [0001] The invention relates to a transportation state monitoring recorder based on a micro-inertial device, in particular to a state monitoring recorder during the transportation of vulnerable items, which belongs to the field of cargo transportation. Background technique [0002] Cargo transportation is an important link in the realization of product functions. During the transportation process, due to factors such as transportation vehicles, environmental conditions, and operators, the goods will inevitably be affected by factors such as shock and vibration, resulting in changes in the performance of the goods. In order to improve the transportation quality of the goods, it is necessary to monitor the transportation status, including environmental information such as shock vibration, temperature, humidity, etc., and to record the data exceeding the set threshold, but the recording instruments used now are large in size and record less data. The use of trad...

In order to improve the transportation quality of the goods, it is necessary to monitor the transportation status, including environmental information such as shock vibration, temperature, humidity, etc., and to record the data exceeding the set threshold, but the recording instruments used now are large in size and record less data. The use of traditional sensor devices consumes a lot of power and cannot work independently, or the battery life is poor, and it is extremely inconvenient to use
