Abstract

The logistic black box in logistic information technology field includes temperature and humidity chip, acceleration chip, electric level converting chip, CPU chip, three data memory chips, power source circuit and standard serial port. The temperature and humidity chip and the three data memory chips are connected in parallel to the universal digital I / O interface of the CPU chip via industrial standard I2C interface, the acceleration chip has signal output connected to the shared digital I / O interface of the CPU chip, the electric level converting chip has input connected to the shared digital I / O interface of the CPU chip and output connected to standard serial port, and all the seven chips have their voltage inputs connected to the 3.6 V voltage output of the power source circuit and ground lines connected to the ground of the power source circuit. The present invention records the vibration, temperature and humidity automatically during logistic process, monitors the logistic behavior effectively and may be used as the important evidence for settlement of claims.

Description

technical field [0001] The invention relates to a device in the technical field of information processing, in particular to a logistics black box. Background technique [0002] How to avoid or reduce rough loading and unloading and loss during transportation has become an important issue in the logistics industry. The logistics black box that can automatically record the temperature, humidity and vibration conditions of the goods during the logistics process has become a need to regulate the logistics market. The logistics black box is mainly used to record the vibration of the goods in the logistics system and the temperature and humidity state. The logistics black box should be attached to the cargo box, so the volume of the logistics black box should be as small as possible; because the logistics cycle may be longer, the logistics black box It is also necessary to record the data that should be recorded in the entire logistics process. The memory space of the recorder tha...
