Description
Technical field
The present invention relates to technical field of security and protection, relate in particular to a kind of asset monitoring based on the RFID technology and theft preventing method.
Background technology
Traditional enterprise asset management, generally depend on assets non-automaticization, record, follow the trail of turnover based on the system of paper document, complete asset management by artificial enforcement enterprises, therefore the efficient of enterprise asset management is extremely low, and the asset size that can manage is also very little.Along with computer application is popularized, the enterprise asset management data information of present most of enterprises has begun to adopt the computer data system management, but data still adopt first paper records, the mode of manual input computing machine is gathered and sorting-out in statistics again.This not only causes the great amount of manpower wasting of resources, and because artificial factor, the data input speed is slow, accuracy rate is low, this traditional mode has been difficult to satisfy quick, the accurately requirement of enterprise asset management, have a strong impact on the operation work efficiency of enterprise, become a big obstacle of restriction enterprise development.
An asset management that application example is the hotel of the asset management system.Current in the hotel supervision for assets mainly be to pass through manual type, mainly be to check by when the guest leaves, making the rounds of the wards for the assets in the room, and to some valuable immovable assets, tend to arrange monitoring camera, the staff comes assets are supervised by checking real-time monitored picture.At some special occasions, can paste an audio magnetic label in assets, at the exit in zone installation check door, in case when assets arrive inspection door, will send alarm sound, manually confirmed by the staff then.And for the asset count in hotel, main mode is at first to give each asset number in the assets registration, then should number by paper labels and be attached on the corresponding assets, when making an inventory, print the assets inventory that all will be made an inventory, the staff one by one does corresponding with the clauses and subclauses on the inventory its numbering after finding assets successively.Finish make an inventory after, disposal data is manual input computer system then.There is following shortcoming in the asset management system in hotel: 1, no matter be that the staff checks room or monitor video, it all is manual operation, check that the room might be careful inadequately, monitor video might be conscientious inadequately, and some artificial errors all may cause assets to lose and not discovery.2, video monitor has the dead angle, and valuable asset especially less to some volumes, that be easy to carry about with one is difficult to monitoring especially.3, employing sound magnetic system is supervised, and can only simply carry out audible alarm, but does not know to cause what the assets of warning are, still need manual intervention, and wrong report sometimes.
At present, the enterprise of various scales all uses infotech (IT) assets, and these assets comprise computing machine, printer, peripherals, personal digital assistant and various similar equipment.It may be challenging safeguarding and follow the tracks of these assets, especially for large-scale enterprise.And this problem may be used by a large amount of employees and become more complicated along with the IT assets, and these employees can be between various different facilities, move beyond the company house even in the whole world.Because the convenience of its portability is so the IT assets may often be misplaced even go adrift.
Therefore, press for a kind of convenience, efficient, intelligentized assets management method, so that can realize automatically the monitoring of assets and antitheft.
