Embodiment 1
Asset location register method principle flow chart as shown in Figure 1, as to provide for the embodiment of the invention 1, wherein,
Step 11 is for every assets are set unique identification.
Here, assets generally are meant capital assets, assets such as printer, file cabinet for example, and these all are the assets of in daily management, often using, and are used for One's name is legion, cause the confusion of management easily.
At first, need to give every assets to set a unique identification, be used for these assets of unique differentiation.In general the unique identification here can be a bar code, is special-purpose bar code of every asset allocation, and the bar code printer through special use prints then, sticks on the assets.Like this, through this bar code just can be unique these part assets of sign.
Step 12 is obtained the positional information (indoor environment adopt finger print data as information data) of every assets.
Here, the position of every assets placement is fixed basically, can obtain the positional information of these assets through handheld terminal.Handheld terminal is exactly the locating device of handing, residing position, accurate location that can be real-time.According to this positioning result, can generate positional information, this is exactly the positional information of these assets.
General, after handheld terminal scans the bar code that is attached on the assets, can be with position, the position of handheld terminal this moment as assets, be about to the wireless signal that current handheld terminal receives and preserve as the positional information of assets present position.
