| 摘要 |
The device of the invention uses at least one measurement chain comprising a sensor sensitive to the magnitude that one wishes to monitor, an analog-to-digital converter capable of supplying a digital signal representative of said magnitude, a microcontroller adapted for taking samples of said digital signal, of associating them with information enabling them to be time-stamped and of memorizing them in a memory that can be accessed by a read module, a logic reactivation circuit making it possible to command an operating period of the microcomputer when the sensor emits a signal announcing the occurrence of a monitored phenomenon. The invention applies particularly to the detection and recording of shocks which may affect goods during transportation thereof.
