Detailed Description
The present application will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present invention.
In the related art, an asset management system installs a tag on a monitored asset, and generally, a paper tag (a barcode, a two-dimensional code, or the like) or a printed passive Radio Frequency Identification (RFID) tag is commonly used. The asset monitoring is mainly to carry out periodic input and inventory through artificial mode, and the mode of manual input is patrolled and examined to the manual work promptly, and the monitoring effect of system is difficult to obtain guaranteeing, mainly has following problem: the checking effect and quality are strongly related to the work responsibility degree of checking workers; the system is in a non-real-time online state, and when equipment is lost, the equipment can be found only by waiting for the next inventory cycle of a worker; the system essentially manages tags, and when the tags are separated from the monitored equipment, the asset management system is difficult to find immediately, with certain delay and hysteresis.
Or, some asset monitoring systems adopting the internet of things communication technology exist in the related technologies, so that the networking of asset tags can be realized, and the automatic checking and monitoring functions can be realized; the system realizes the functions of warning the movement of assets and the like through a light ray induction sensor, an acceleration sensor and the like. However, there are certain vulnerabilities in the above systems: some electronic tag management systems adopt a single light sensing mode or an acceleration sensor mode to perform asset displacement or tag falling alarm, for example, a light sensing sensor covers a sensor to change light intensity when a tag is installed, and light directly irradiates the sensor to generate difference when the tag falls, so that tag falling alarm is realized; under the night condition, the light induction sensor cannot detect whether the label is taken down from the equipment or not, and certain loopholes exist; in addition, if the light induction sensor is not tightly pasted or the stained surface has certain light transmittance, the light intensity can also change according to the external brightness, so that false alarm is generated; the acceleration sensor generates an alarm when the supervised asset is moved or the label is taken down, and the acceleration is from the two situations that the asset is moved or the label is taken down, so the false alarm situation cannot be avoided. Therefore, the asset monitoring system of the communication technology of the internet of things in the related art cannot distinguish whether the device for asset positioning is taken down intentionally, and the stability and reliability of the asset monitoring system of the communication technology of the internet of things are challenged in practical application.
Based on the problems existing in the existing asset monitoring method, the embodiment of the application provides an asset monitoring method, which can solve the technical problems and disadvantages that cannot be solved in the prior art.
Fig. 1 shows an alternative flowchart of an asset monitoring method provided in an embodiment of the present application, which will be described according to various steps.
Step S101, the monitoring equipment establishes an incidence relation of a passive tag corresponding to the monitoring equipment.
In some embodiments, the establishing, by the monitoring device, an association relationship with a passive tag corresponding to the monitoring device includes: the monitoring equipment sends the secret key of the passive tag to a server when detecting that the secret key of the passive tag corresponding to the monitoring equipment is a non-initial secret key. The server matches the non-initial secret key sent by the monitoring equipment to the server with the secret key stored in the server, and when the matching result is consistent, the passive tag can be normally used, and the monitoring equipment supervises the association relationship with the passive tag corresponding to the monitoring equipment; and under the condition that the matching results are inconsistent, the passive tag is an abnormal tag, and the server restores the abnormal tag to the initialized state.
In some embodiments, the establishing, by the monitoring device, an association relationship with a passive tag corresponding to the monitoring device includes: the method comprises the steps that when the monitoring equipment detects that a secret key of a passive tag corresponding to the monitoring equipment is an initial secret key, the monitoring equipment sends the initial secret key of the passive tag to a server; the monitoring equipment receives a key modification instruction sent by the server, generates a random key according to the key modification instruction, and modifies the key of the passive tag into the random key.
In some embodiments, when the monitoring device detects that the key of the passive tag corresponding to the monitoring device is the initial key, the sending, by the monitoring device, the initial key of the passive tag to the server includes: the monitoring equipment reads the UID of the passive tag and accesses the secret key of the passive tag through the authority; and sending the initial key of the passive tag to a server under the condition that the key read by the monitoring equipment from the passive tag is the initial key.
In some embodiments, the server receives an initial key of the passive tag, and sends a key modification instruction to the monitoring device when finding that the key of the passive tag is the initial key. The key modification instruction is used for instructing the monitoring equipment to modify the key of the passive tag.
In some embodiments, the monitoring device receives a key modification instruction sent by the server, generates a random key, modifies the key of the passive tag according to the key modification instruction, and modifies the initial key of the passive tag into the random key. And the monitoring equipment sends the random secret key to the server.
In some embodiments, the monitoring device sending the random key to the server further comprises: and the monitoring equipment sends the random key and at least one of the UID of the monitoring equipment and the UID of the passive tag to the server.
In this way, the monitoring device establishes an association relationship with the passive tag by modifying the key of the passive tag. The association relationship may be a unique binding relationship of the monitoring device and the passive tag. When the passive tag is damaged or lost, or the asset monitored by the monitoring equipment is changed, the monitoring equipment only needs to establish an association relationship with another passive tag again. The reusability of the monitoring equipment is improved, and the overall cost of the monitoring system is reduced.
Step S102, the monitoring device reads the UID of the passive tag corresponding to the monitoring device and the key of the passive tag.
In some embodiments, the reading, by the monitoring device, the UID of the passive tag corresponding to the monitoring device and the key of the passive tag includes: the monitoring equipment periodically reads the UID of the passive tag corresponding to the monitoring equipment and the key of the passive tag according to a first time threshold. The first time threshold is a preset monitoring time interval.
In other embodiments, the monitoring device periodically reads the UID of the passive tag and the key of the passive tag corresponding to the monitoring device according to a first time threshold, and uploads the UID of the passive tag and the key of the passive tag to a server.
In some embodiments, the first time interval may also be set according to a historical monitoring period.
Step S103, determining the state of the asset monitored by the monitoring equipment according to the UID of the passive tag and the key of the passive tag.
In some embodiments, the server receives the UID of the passive tag and the key of the passive tag uploaded by the monitoring device, and determines the status of the asset monitored by the monitoring device according to the UID of the passive tag and the key of the passive tag.
In other embodiments, the monitoring device reads the UID of the passive tag and the key of the passive tag, and determines the status of the asset monitored by the monitoring device according to the UID of the passive tag and the key of the passive tag.
In some embodiments, determining the status of the asset monitored by the monitoring device from the UID of the passive tag and the key of the passive tag comprises: and under the condition that the UID of the passive tag read by the monitoring equipment and the key of the passive tag are not changed, and the path for the monitoring equipment to send the UID of the passive tag and the key of the passive tag to the server is consistent with the path for the monitoring equipment to send the initial key of the passive tag to the server, the monitoring equipment determines that the state of the asset is normal.
In other embodiments, the monitoring device reading no change in both the UID of the passive tag and the key of the passive tag includes: the UID of the passive tag read by the monitoring equipment is the same as the UID of the passive tag stored by the server; the key of the passive tag read by the monitoring device is the same as the key of the passive tag stored by the server. The sending of the key of the passive tag to the server and the sending of the initial key of the passive tag to the server by the monitoring device are consistent, and the sending comprises: and the monitoring equipment sends the read secret key of the passive tag to the route and the gateway of the server, and the route and the gateway are consistent with the route and the gateway which are sent by the monitoring equipment to the server by the initial secret key of the passive tag.

The lack of extensive movement of the asset includes: the assets are still within the coverage of the network in which the monitoring devices and servers are located.
In some embodiments, determining the status of the asset monitored by the monitoring device from the UID of the passive tag and the key of the passive tag comprises: and under the condition that the monitoring equipment cannot read the UID of the passive tag corresponding to the monitoring equipment and the key of the passive tag, the monitoring equipment determines that the state of the asset is abnormal.
In other embodiments, the failure of the monitoring device to read the UID of the passive tag and the key of the passive tag corresponding to the monitoring device includes: the passive tag is torn or destroyed, the monitoring device cannot read the UID of the passive tag and the key of the passive tag corresponding to the monitoring device, or the monitoring device leaves the asset, and the UID of the passive tag and the key of the passive tag cannot be read if the distance between the monitoring device and the corresponding passive tag is too far.
In still other embodiments, the status of the asset as abnormal includes: the passive tag is torn or destroyed or the monitoring device is removed.
In some embodiments, determining the status of the asset monitored by the monitoring device from the UID of the passive tag and the key of the passive tag comprises: and under the condition that the UID of the passive tag read by the monitoring equipment is consistent with the UID of the passive tag stored in the server, and the key of the passive tag read by the monitoring equipment is inconsistent with the key of the passive tag stored in the server, the monitoring equipment determines that the state of the asset is abnormal.
In other embodiments, the reading, by the monitoring device, of the UID of the passive tag to be consistent with the UID of the passive tag stored in the server, and the reading, by the monitoring device, of the key of the passive tag to be inconsistent with the key of the passive tag stored in the server includes: the passive tag is duplicated. The key area of the passive tag is protected by encryption, and when the passive tag is copied, the data in the key area cannot be copied, and only the UID of the passive tag can be copied. Therefore, in the case where the passive tag is copied, the UID of the passive tag read by the monitoring device is the same as the UID of the passive tag stored by the server, but the key of the passive tag read is different from the key of the passive tag stored by the server.
In some embodiments, determining the status of the asset monitored by the monitoring device from the UID of the passive tag and the key of the passive tag comprises: and under the condition that the UID of the passive tag read by the monitoring equipment and the key of the passive tag are not changed, and the path for the monitoring equipment to send the UID of the passive tag and the key of the passive tag to the server is inconsistent with the path for the monitoring equipment to send the initial key of the passive tag to the server, the monitoring equipment determines that the state of the asset is abnormal.
In some embodiments, the UID of the passive tag read by the monitoring device and the key of the passive tag are not changed, and a path through which the UID of the passive tag and the key of the passive tag are sent to the server by the monitoring device is inconsistent with a path through which the initial key of the passive tag is sent to the server by the monitoring device, which indicates that the monitoring device and the passive tag are still installed on the monitored asset, and the asset is moved and leaves a network when the monitoring device establishes an association relationship with a passive identifier, so that a path through which the monitoring device sends information to the server is inconsistent with a path through which the initial key of the passive tag is sent to the server by the monitoring information.
In some embodiments, the monitoring device reports the abnormal status information of the asset to the server. The abnormal state information includes: the passive tag is torn or destroyed, the monitoring device is removed from the asset, the passive tag of the asset is copied, and the asset is moved over a wide range. And/or the monitoring equipment reports the position information of the assets to the server.
Thus, an association relationship is established between the monitoring equipment and the passive tag, the UID of the passive tag corresponding to the monitoring equipment and the key of the passive tag are read by the monitoring equipment, and the state of the asset monitored by the monitoring equipment is determined according to the UID of the passive tag and the key of the passive tag; the method can monitor the assets in real time, and the monitoring equipment can sense and find the assets in time under the conditions that the assets are moved in a large range, the passive tags are damaged, the monitoring equipment is detached and the passive tags are copied, and meanwhile, the monitoring equipment is searched according to the position information reported by the monitoring equipment. And the monitoring equipment has the advantage of being reusable, and can be remotely paired and bound with a passive tag. Under the condition that the label needs to be replaced or torn, the monitoring equipment can establish an incidence relation with another passive label, so that the repeatable utilization rate of the monitoring system is improved, and the manufacturing cost of the monitoring system is reduced.
