Background technology
Existing physical distribution monitoring system, by the variable classification of monitoring, is mainly divided into two classes, and a class is that logistics vehicles and the residing environment of goods are monitored.For example, GPS/ Big Dipper logistic track system, can monitor the positional information of haulage vehicle in real time.On this basis, add temperature-humidity sensor etc., can also monitor in real time the residing environment of goods.Equations of The Second Kind is the system that goods itself manages.For example, utilize bar code, RFID monitoring goods whether within certain scope.Also have GPS/ Big Dipper monitoring position and cargo monitoring combined.For example, whether the logistics anti-theft monitoring system (application publication number CN 103295108 As) of patent of invention based on RFID and 3G technology, in utilizing 3G monitoring haulage vehicle position, also utilize RFID technology monitoring goods itself on haulage vehicle.
The defect of above-mentioned supervisory system is:
1. the ability of the combined monitoring of pair environment and goods information is also not enough, cannot while monitoring goods information and goods environmental information of living in.
2. the support of pair multiple monitoring environment is also not enough.For example, some systems are for the monitoring of vehicle environment, the monitoring for fixed-site having, the monitoring for maritime environment having.But versatility is poor, for example vehicle-mounted supervisory system can not be used for fixed environment.
3. existing supervisory system, for the situation of multi-point monitoring, lacks information interaction between two control points, can only be by server end or people for carrying out information interaction, and this causes real-time, the reliability variation of system.For example, utilize multiple rfid systems to monitor the goods in several regions, in the time that a rfid system has monitored a RFID label and has departed from from guarded region, whether enter another RFID supervisory system if inquire about this label by server end, real-time is bad, if but directly report to the police, likely cause erroneous judgement.
