Problems solved by technology
Most of the existing logistics safety recorders are equipped with only one CPU. Since data processing and storage will take a certain amount of time to complete, when the environmental factors of the recorder are complex and it is necessary to record multiple data at the same time (for example, simultaneous recording Temperature, humidity, shock, vibration and other factors), it is very easy to cause data loss due to CPU too late to process, resulting in poor data integrity of the recorder, unable to complete continuous acquisition
Moreover, due to the small processing capacity of the single-CPU recorder, its application range is also small. The maximum impact value of the existing comprehensive recorder is only 70G (X, Y, Z three directions, each direction allows recording maximum effective impact value), which cannot meet the actual use requirements in the transportation process

The invention relates to a dual-core comprehensive logistics recording instrument which is characterized by comprising a first CPU (central processing unit), a second CPU, an acceleration sensor, an SD card module, a USB (universal serial bus) interface module, an indicator light module, a key module, a temperature and humidity sensor, a power management module and a battery module, wherein the first CPU is connected with the second CPU, the SD card module, the USB interface module, the indicator light module, the key module, the temperature and humidity sensor, the power management module and the battery module, and the acceleration sensor is connected with the second CPU. The structure with two CPUs is adopted, so that the data processing capacity is greatly improved, various data can be rapidly and comprehensively recorded under complicated conditions, the data are uninterruptedly recorded without loss in real time, and the continuity and the integrity of the data are guaranteed. A recording method for the dual-core comprehensive logistics recording instrument has the advantages of high processing speed, large data size, and wide scope of application.
Description
technical field [0001] The invention belongs to the field of packaging and transportation monitoring instruments, in particular to a dual-core logistics safety comprehensive recorder and a recording method thereof. Background technique [0002] At present, logistics transportation is an important link in national production. The packaged goods are often damaged due to various reasons in the logistics and transportation link. Most of the existing logistics monitors are used to comprehensively monitor whether there is unpacking, changes in temperature and humidity, and impacts during the transportation of goods. Most of the existing logistics safety recorders are equipped with only one CPU. Since data processing and storage will take a certain amount of time to complete, when the environmental factors of the recorder are complex and it is necessary to record multiple data at the same time (for example, simultaneous recording Temperature, humidity, shock, vibration and other ...
