Next, embodiments of the present application will be described in detail.
An embodiment of the present application provides an asset location method, which is applied to a handheld device, as shown in fig. 1, and the method may include the following steps:
s11, receiving navigation information which is sent by the cloud platform and used for positioning assets of at least one target passive RFID tag in a target equipment warehouse.
In this step, the navigation information includes the entrance position of the equipment warehouse, the identification information of all the target passive RFID tags, and the identification information of a plurality of non-target passive RFID tags.
S12, receiving a positioning instruction input by an administrator at the entrance position.
S13, judging whether the first passive RFID tag is a target passive RFID tag according to the identification information of the first passive RFID tag included in the navigation information; if not, executing step S14; when the determination result is yes, step S15 is performed.
S14, positioning a first passive RFID tag by using the maximum transmitting power and the second maximum transmitting power, and after the first passive RFID tag is positioned, taking one passive RFID tag positioned behind the first passive RFID tag as the first passive RFID tag in the navigation information, and returning to execute the step S13 until all target passive RFID tags are positioned.
S15, positioning a first passive RFID tag by using the maximum transmitting power, the second maximum transmitting power and the minimum transmitting power, displaying the first passive RFID tag to an administrator for positioning confirmation after the first passive RFID tag is positioned, taking one passive RFID tag which is included in the navigation information and is positioned behind the first passive RFID tag as the first passive RFID tag, taking the next passive RFID tag in the navigation information as the first passive RFID tag, and returning to execute the step S13 until all target passive RFID tags are positioned.
It should be noted that in the embodiment of the present application, an administrator may attach a passive RFID tag to each asset in the equipment store, and attach a passive RFID tag to the rack/shelf where multiple assets are stored. And, the manager can scan the passive RFID tags in batches by using the handheld device, and upload the passive RFID tags to the cloud platform, and the cloud platform establishes the binding relation between the passive RFID tags on the rack/shelf and the passive RFID tags on the assets on the rack/shelf.
When the cloud platform determines the asset of at least one target passive RFID tag in the target equipment warehouse to be positioned, the cloud platform can create navigation information for guiding the handheld equipment to position all the target passive RFID tags based on the binding relation established locally, and sends the navigation information to the handheld equipment.
In one example, the cloud platform may determine, from a positioning instruction input by an administrator at the cloud platform side, an asset to which a target passive RFID tag to be positioned belongs.
Of course, the cloud platform may also determine the asset to which the target passive RFID tag to be located belongs in other ways, which are not listed here.
In addition, the navigation information may be created by the cloud platform based on the locally configured creation rule and the binding relationship.
Specifically, when the handheld device executes the step S13, it may be determined whether the identification information of the first passive RFID tag included in the navigation information includes a specified mark; when the judging result is yes, determining that the first passive RFID tag is the target passive RFID tag; and when the judging result is negative, determining that the first passive RFID tag is not the target passive RFID tag.
The handheld device may broadcast the radio frequency signal using the maximum transmit power when executing step S14; if the response signal for the radio frequency signal sent by the first passive RFID tag is received for the first time, continuing broadcasting the radio frequency signal by using the next-largest transmitting power; and if the response signal for the radio frequency signal sent by the first passive RFID tag is received again and the measured signal strength of the first passive RFID tag is larger than the set threshold value, determining to locate the first passive RFID tag.
The handheld device may broadcast the radio frequency signal using the maximum transmit power when executing the step S15; if the response signal for the radio frequency signal sent by the first passive RFID tag is received for the first time, continuing broadcasting the radio frequency signal by using the next-largest transmitting power; if the response signal sent by the first passive RFID tag and aiming at the radio frequency signal is received again and the measured signal strength of the first passive RFID tag is larger than a set threshold value, continuing broadcasting the radio frequency signal by using the minimum transmitting power; and if the response signal for the radio frequency signal sent by the first passive RFID tag is received again, determining to locate the first passive RFID tag.
The above-mentioned threshold setting is set and configured on the handheld device by the administrator according to the asset location experience. For example, the set threshold may be-30 dbm or the like.
In the embodiment of the present application, the cloud platform may send the map of the target device storehouse together when sending the navigation information to the handheld device. Thus, when the handheld device locates the non-target RFID tag, the position of the non-target RFID tag is displayed on the map in real time so as to assist the administrator in moving towards the next RFID tag.
The asset location method described above is described in detail with reference to specific embodiments.
Suppose that the cloud platform needs to locate assets within the equipment library 1 to which passive RFID tags identified as 1C-4, 1B-11, and 1A-15 belong. Wherein the asset to which the passive RFID tag identified as 1C-4 belongs is on a 1C-S rack; the asset to which the passive RFID tag identified as 1B-11 belongs is on a 1B-S rack; the asset to which the passive RFID tags identified as 1A-15 belong is on a 1A-S rack.
And the cloud platform sends navigation information to the handheld device. The navigation information includes the entrance position of the equipment warehouse 1, the identification information of all the target passive RFID tags and the identification information of a plurality of non-target passive RFID tags, and the specific contents are as follows: the entrance location of equipment library 1, 1D-1,1C-2,1C-4, 1C-6,1C-8,1B-9,1B-11, 1B-9,1A-8,1A-10,1A-12,1A-14,1A-15.
Here, the tag-bearing identification is the identification information of the target passive RFID tag, and the remaining identifications are the identification information of the non-target passive RFID tags.
The asset to which the passive RFID tag identified as 1D-1 belongs is on a 1D-S rack; the asset to which the passive RFID tag identified as 1C-2 belongs, the asset to which the passive RFID tag identified as 1C-6 belongs and the asset to which the passive RFID tag identified as 1C-8 belongs are on a 1C-S rack, and the asset to which the passive RFID tag identified as 1C-4 belongs are on the same rack; the assets of the passive RFID tag identified as 1B-9 are on the 1B-S rack and the assets of the passive RFID tag identified as 1B-11 are on the same rack; the asset to which the passive RFID tag identified as 1A-8 belongs, the asset to which the passive RFID tag identified as 1A-10 belongs, the asset to which the passive RFID tag identified as 1A-12 belongs, and the asset to which the passive RFID tag identified as 1A-14 belongs are on the 1A-S rack and on the same rack as the asset to which the passive RFID tag 1A-15 belongs.
The handheld device receives the navigation information and judges whether the identification information of the first passive RFID tag included in the navigation information is included or not after receiving a positioning instruction input by an administrator at the entrance position of the equipment warehouse 1; since 1D-1 is not present, the result of the determination is no, and the handheld device uses the maximum transmit power to broadcast the rf signal; if the response signal for the radio frequency signal sent by the passive RFID tag with the identification of 1D-1 is received for the first time, continuing broadcasting the radio frequency signal by using the next-largest transmitting power; if the response signal sent by the passive RFID tag identified as 1D-1 and aiming at the radio frequency signal is received again, and the measured signal intensity of the passive RFID tag identified as 1D-1 is larger than-30 dbm, determining that the first passive RFID tag is positioned, namely, positioning the asset to which the first passive RFID tag belongs.
Next, taking 1C-2 in the navigation information as identification information of a first passive RFID tag, and judging whether the 1C-2 includes the information; since 1C-2 is not present, the result of the determination is no, and the handheld device uses the maximum transmission power to broadcast the radio frequency signal; if the response signal for the radio frequency signal sent by the passive RFID tag with the identifier of 1C-2 is received for the first time, continuing broadcasting the radio frequency signal by using the next-largest transmitting power; if the response signal sent by the passive RFID tag identified as 1C-2 and aiming at the radio frequency signal is received again, and the measured signal intensity of the passive RFID tag identified as 1C-2 is larger than-30 dbm, the passive RFID tag identified as 1C-2 is determined to be positioned, namely, the asset to which the passive RFID tag identified as 1C-2 belongs is positioned.
Continuing to take 1C-4 in the navigation information as the identification information of the first passive RFID tag, and judging whether the 1C-4 comprises the identification information; since 1C-4 includes, the determination result is yes, and the handheld device uses the maximum transmitting power to broadcast the radio frequency signal; if the response signal for the radio frequency signal sent by the passive RFID tag with the identification of 1C-4 is received for the first time, continuing broadcasting the radio frequency signal by using the next-largest transmitting power; if the response signal sent by the passive RFID tag with the mark of 1C-4 is received again and the measured signal strength of the first passive RFID tag is greater than-30 dbm, continuing broadcasting the radio frequency signal by using the minimum transmitting power; if the response signal sent by the passive RFID tag identified as 1C-4 is received again, determining that the passive RFID tag identified as 1C-4 is located, that is, locating the asset to which the passive RFID tag identified as 1C-4 belongs.
The specific locating process is similar to the locating process of the passive RFID tag identified as 1D-1 for the remaining passive RFID tags included in the navigation information, and will not be described in detail herein.
The remaining passive RFID tags included in the navigation message are similar to the passive RFID tag identified as 1C-4, and will not be described in detail herein.
It should be noted that, during the whole positioning process of positioning 1C-4, 1B-11, and 1A-15, the handheld device is in a state of being continuously moved by the administrator.
According to the technical scheme, in the embodiment of the application, a fixed reader is not required to be arranged in the equipment warehouse, and when the asset of at least one target passive RFID tag in the target equipment warehouse is required to be positioned, the handheld equipment can directly position the corresponding asset based on the navigation information of the asset of the passive RFID tag issued by the cloud platform, so that the deployment cost of the equipment warehouse is saved, and the positioning time is shortened.
