Transportation of biological/chemical materials is a critical task. The chemical materials carry the risk of being flammable, explosive and corrosive and so on. When exposed, these materials may cause hazards, either to humans or environmental or both. Biological materials may be of several kinds: infectious and affecting humans or animals, clinical specimens, medical waste etc. when exposed, the infectious biological materials are capable of causing temporary or permanent disability, life threatening or fatal disease to humans or animals. Under these circumstances, taking proper measures becomes a necessary condition while transporting chemical or biological materials.
The national or international agencies have prescribed categories and guidelines for packing and transporting such materials. The materials may be sent by cargo aircraft, by road transport, by courier or by post. In any case, the packaging must meet classification and labeling requirements.
In addition to ensuring that the material being transported is appropriately packaged (i.e. as per the requirements of the transporter or as per government norms or as per industry norms, as the case may be), there has been a growing need to transport chemical or biological materials under controlled environment.

A sample dynamic barcode generated by the packaging element is shown in
The dynamic barcode further indicates that current Ambient Temperature, as sensed by a temperature sensor, has a value of 23.67° C. (as represented by “nAT23.67”). The dynamic barcode further indicates that the current humidity level has a value of 45.67% (as represented by “nH45.67”); the current pH level has a value of 6.78 (as represented by “nPH6.78”); the current liquid temperature has a value of 28.92° C. (as represented by “nLT28.92”); the current level of volatile contents is 15.5 (as represented by “nVC15.05”).
The dynamic barcode may further include a time stamp (in dd-mm-yy-hh-mm_ss format) indicating the current time, as represented by “nTS0304171230_30”.
Apart from the above, the dynamic barcode further more provides the range of data that can be used either for alert purposes or for activate a solution to control the system. In this regard, “nATMX8.00-ATMN1.50” indicates that the Ambient Temperature should be maintained between a Maximum Ambient Temperature of 8° C. and a Minimum Ambient Temperature was −1.5° C. If Ambient Temperature at any point of time falls outside the prescribed range of 8 to −1.5, an alert condition is prevailing and a corrective action may need to be implemented.
Likewise, “nHMX10.00-HMN5.00” indicates that the Humidity should be maintained between a Maximum of 10% and a Minimum of 5%. If Humidity at any point of time falls outside the prescribed range of 5 to 10%, an alert condition is prevailing and a corrective action may need to be implemented.
Likewise, “nLTMX5.00-LTMN2.00” indicates that the liquid temperature should be maintained between a Maximum of 5° C. and a Minimum of 2° C. If liquid temperature at any point of time falls outside the prescribed range of 2° C. to 5° C., an alert condition is prevailing and a corrective action may need to be implemented.
Likewise, “nVCMX15.0-VCMN5.0” indicates that the volatile content's level should be maintained between a Maximum of 15 and a Minimum of 5. If volatile content's level at any point of time falls outside the prescribed range of 5 to 15, an alert condition is prevailing and a corrective action may need to be implemented.
Thus, it can be observed that by reading the dynamic barcode and reading the content thereof, it is possible to arrive at the following conclusions:
It may be noted that it is not essential to define an alert condition or a criterion for invoking a corrective action in respect of each physical parameter that can be measured. It can be seen in the above example, that while pH value is being measured and depicted in the barcode, an alert condition or a criterion for invoking a corrective action are not defined.
The invention enables to continuously monitor the health of the material under transportation, i.e. constantly monitoring environmental parameters related to the chemical or biological material under transportation.
The present invention can not only log information, but also understand patterns and can be viewed and transmitted using IOT technology.
The invention enhances the sensor with decision making abilities. Whenever there is a minute change in any of the parameters the sensor can notify an alert to the main control.
The invention enables the tracking to be performed with the aid of dynamic data that can be viewed in a barcode format on the container.
