Description

 Specification Name of Invention: A Method and System for Supervision of Materials in Special Workplaces

 [0001] Embodiments of the present invention relate to the field of smart workplaces, and in particular, to a method and system for monitoring materials in a special workplace.

 Background technique

 [0002] Some special workplaces such as nuclear power plants, oil wells, mines, large terminals or military ports, strategic warehouses, etc., require strict supervision of important materials stored in these locations due to their special requirements for operations. For example, nuclear fuel or nuclear waste stored in a nuclear power plant, once it falls outside the place specified in the nuclear power plant or nuclear power plant, the consequences will be unimaginable, so it needs to be strictly regulated; for example, fire or rescue tools in oil wells or mines, as soon as they are needed It is an urgent need for 100,000 rushes, and the specific location of its storage needs to be clear; similarly, the materials stored in special operations such as large docks, military ports or strategic warehouses need to be strictly regulated for similar reasons.

 [0003] In order to solve the problem of material supervision in the above-mentioned special workplaces, the method used by the industry is to manage the materials in the special working place through positioning, that is, through some positioning technologies, it is possible to know that the materials are in the special working place. The place of storage, so that you can find it when you need it. At present, the two typical positioning technologies, Global Positioning System (GPS) and Radio Frequency Identification (RFID), are relatively mature. The industry has introduced GPS or RFID into the supervision of materials in special workplaces. However, these two positioning technologies have inherent limitations in the supervision of materials in special workplaces. Taking GPS technology as an example, its satellite signal is easily blocked by obstacles such as buildings in special work places, and it cannot be accurately positioned. In some special work places, the floor space is huge, the buildings are relatively high, and the relative size needs to be positioned. Smaller materials are obviously unrealistic, while R FID technology is suitable for positioning small objects. However, RFID signals are more susceptible to environmental interference and do not reflect the actual trajectory of the label. For example, The transportation of materials from one location in a special workplace (whether it is illegally transported) to another location, RFID does not reflect this process.

 [0004] Therefore, new technologies are needed to overcome the above-mentioned deficiencies in the methods of material supervision in special workplaces.

These inquiring terminals can be connected to the central server by wire or wirelessly, and can be either a fixed terminal such as a personal computer (PC) or a mobile terminal such as a smart phone or a tablet computer. By querying the human-computer interaction interface provided by the terminal, the relevant personnel of the special work place can input the number or identity information of the supervised materials in the special work place, and can query the storage location and status information of the material, for example, the specific storage In which place in the special work place, whether it is the warehousing status or the outbound status, where is the warehousing, and who is out of the library, etc.

[0059] From the method for supervising the material in the special workplace as exemplified in FIG. 1 above, the positioning server may fix the electronic tag according to the positioning algorithm and the engraving pair of the at least three base stations each receiving the ultra-wideband pulse signal. The location of the materials in the special work place. Since the electronic tag fixed in the special work place transmits the ultra-wideband pulse signal, it has the characteristics of frequency bandwidth, multi-channel, low power consumption, low interference, high safety factor and coexistence with the existing spectrum.
