Realize the method that network object intelligence is followed the trail of
Technical field
The present invention relates to object tracing monitoring field, particularly a kind of method that realizes the tracking of network object intelligence.
Background technology
Asset management is an importance of industry and commerce.For example, in logistics transportation, valuables require monitoring position information in real time, and fragile article require the information such as real-time monitoring temperature, humidity, light intensity.The network platform of good data acquisition and processing, can reduce costs, and reduces time loss, and the security that improves assets, and has good user to experience.
Bar codes technique is a kind of item tracing technology of generally applying now.For example, in, express delivery industry, use bar code to pay object; Retail trade utilizes bar code to manage commodity.But the weak point of bar codes technique is each time product to be followed the trail of and all needed manual scanning.
REID (RFID) is another kind of widely used item tracing technology.It does not need manual scanning, applies to some extent at aspects such as retail trade, automobile, railway, air transportations.But RFID can not provide the information of article environment of living in.
Existing sensor-based material flow tracking system, can apply multiple sensors, gather the much informations such as the position of tracked article and the temperature of environment of living in, humidity, light intensity, in real time or periodically data are sent to service centre, service centre processes sensor information.User can inquiry service center data, take corresponding action, or the rule that service centre sets according to user is directly moved.
There are two weak points in existing material flow tracking system:
One, Sensor section is mainly based on sensors such as the GPS/ Big Dipper, temperature sensor, humidity sensor, light activated elements, collects the information of environment of living in, directly sends data to service centre.This single sensor institutional framework can not realize the self-management of sensor, such as: the coordination between the collection of minimizing redundant data, the diagnosis of fault and recovery, multiple sensing system.
Two, Data Source only relies on sensor, this single Data Source can cause the reliability of system and fault freedom not high.Such as, humidity sensor measurement has deviation, and service centre is difficult to automatically correct; For another example, the communication of system is broken down, and that server just can not obtain the information of client completely.
For two above problems, the present invention is intended to by the structure of sensor level network, improves the intelligent of sensing network, as coordinated between highly effective gathering data, automatic trouble diagnosis and recovery, multisensor network.The present invention also can change the unicity of Data Source, thereby improves reliability and the fault-tolerance of system.
