[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The RFID (radio frequency identification) is a non-line-of-sight non-contact automatic identification technology, which is a technology for realizing information exchange with an object to be identified by transmitting a wireless radio frequency signal by utilizing spatial coupling.
The working principle of the RFID is as follows: in the coverage range of the RFID reader, if the RFID tag is a passive tag, the RFID tag receives a radio frequency signal sent by the RFID reader, induces the radio frequency signal to obtain energy, and loads information stored in the RFID tag (which is an electronic tag) onto the radio frequency signal by using the energy and then sends the information back to the RFID reader. If the RFID tag is an active tag, the RFID tag actively transmits a radio frequency signal with stored information to the RFID reader.
Compared with the traditional bar code, the RFID label has the following advantages:
the RFID label can perform multiple read-write operations;
larger data storage capacity and higher data transmission rate;
data transmission can be operated without being in a line of sight;
the reading distance is long;
the RFID reader can be communicated with a plurality of RFID labels at the same time, so that the speed is higher and the time is saved;
the safety is higher;
the environment adaptability and the durability are stronger;
is not easy to be copied;
the reading reliability and accuracy are higher;
the identification time is short, manual intervention is not needed, and the automatic operation is realized.
Based on the above characteristics of the RFID, the asset information acquisition of the data center is performed using the RFID technology in the embodiment of the present invention.
Fig. 1 is a schematic view of an asset information acquisition system of a data center according to an embodiment of the present invention, and as shown in fig. 1, the asset information acquisition system mainly includes: RFID readers, antennas, and RFID tags on the assets of the data center. The system can further comprise a monitoring unit or a back-end management module.
The RFID reader reads RFID tags on all assets of the data center through an antenna, and asset information read from the RFID tags is input into a rear-end management module for asset management.
The key point of the invention is how to reasonably and skillfully arrange the RFID tags on the antennas and the assets of the data center, thereby more effectively managing the assets. The following are described in detail one by one:
the antenna may preferably be a wire antenna, but may be another antenna because the wire antenna has the strongest coverage capability, and when another antenna is used, a plurality of antennas may be arranged to achieve a better coverage capability. The antenna is preferably compatible with near field and far field RFID tag identification characteristics.
In addition, the layout position of the antenna needs to be ensured to be capable of reading the RFID tags on the assets in the cabinet governed by the antenna, and in order to enable the antenna to well cover the RFID tags in the cabinet, the antenna is usually disposed inside the cabinet, and preferably, the antenna can be disposed on the cabinet door or near the door frame inside the cabinet. Thus, the read range of the RFID tag covers the entire cabinet. The specific position of the antenna can be adjusted appropriately according to the signal strength. The position of which may be as indicated in fig. 2.
The RFID tags may be passive or active RFID tags with a strong read capability on or near a metal surface. In the embodiment of the invention, the following four types of labels are provided according to different purposes: cabinet tags, location tags, equipment tags, and false panel tags.
And the cabinet label comprises cabinet information such as the position, the purpose, the manufacturer, the model, the specification and the like of the cabinet. The cabinet label is disposed on the cabinet, for example, on a door frame of the cabinet, as indicated in fig. 2.
And the position label comprises the position information of the position label. The location tags are placed at various locations in the cabinet, such as on a square hole bar on one side of the cabinet, opposite the antenna location, as indicated in fig. 2. A position tag may be deployed in the cabinet for each U (height unit of the cabinet), corresponding to the order of the cabinet's U's. When the location is empty, the location tag may be read by an RFID reader via an antenna. When equipment, a wire arranging tray or a metal false panel exists at a certain position, the position label at the position is shielded and cannot be read by an RFID reader through an antenna. When the equipment, the wire arranging tray or the metal false panel at the position are removed, the position label at the position is shielded and eliminated, and the RFID reader can continuously read the position label through the antenna. However, due to the electromagnetic wave transmission characteristic of the plastic dummy panel, when the plastic dummy panel exists at a certain position, the position tag at the position can still be read by the RFID reader through the antenna.
Device tags contain device information such as name, model, usage, power consumption, volume, vendor, technical support, etc. Arranged on the device, preferably on the front panel of the device, facilitating antenna reading, as indicated in fig. 2. The device label may be placed directly on the device at the time of shipment, such as in the blank of the front panel of the device. Devices herein may include, but are not limited to: network equipment such as switches, firewalls, etc., distribution frames, IT equipment such as servers, storage devices, etc.
The false panel label comprises false panel information, the false panel generally comprises two materials of plastic and metal, each material corresponds to one type of label, and the three specifications of 1U, 2U and 4U are generally provided, so that the false panel label comprises information of specification, material and the like. The dummy panel is used for shielding the blank area of the cabinet, optimizing the heat dissipation channel of the cabinet and beautifying the appearance of the cabinet. After the metal false panel is placed into the cabinet, the position tag at the corresponding position can be shielded, the position tag at the position cannot be read by the RFID reader through the antenna, and after the plastic false panel is placed into the cabinet, the position tag at the corresponding position cannot be shielded, and the position tag at the position can be read by the RFID reader through the antenna. The false panel label is disposed on the false panel, as may be indicated in fig. 2.
There are two specifications for current RFID readers: single cabinet RFID readers and multiple cabinets RFID readers. The single cabinet RFID reader supports 1-2 antennas, an Ethernet interface and USB power supply, and one antenna can be arranged in each 2 cabinets. The multi-cabinet RFID reader supports 4-8 antennas, an Ethernet interface, 220V alternating current power supply and a detachable antenna splitter, and one cabinet can be arranged in each row. Any one of the specifications may be adopted in the present invention.
The triggering of the RFID reader may be manually triggered or automatically triggered, but preferably, the triggering may be triggered by opening and closing of a cabinet door. At this time, as shown in fig. 1, the system may further include a monitoring unit. The monitoring unit is responsible for monitoring opening and closing of the cabinet door, and when the opening and closing of the cabinet door are detected, the RFID reader is triggered to read RFID tags on all assets of the data center through the antenna. The triggering of the RFID reader by the monitoring unit can be realized by the back-end management module (the manner is shown in fig. 1), that is, the monitoring unit notifies the back-end management module of the information that the cabinet door is monitored to open and close, and the back-end management module triggers the RFID reader to read the RFID tag on each asset in the data center through the antenna.
Wherein, the monitoring that the monitoring unit was gone on opening and shutting the rack door can be realized through carrying out the communication with rack door magnetism, and door magnetism is the device that is used for surveying whether opened or remove such as door and window drawer, and the monitoring unit just can learn opening and shutting of rack door through carrying out the communication with rack door magnetism.
Generally, when the RFID reader scans the RFID tags, one-time scanning can be completed in about 5 seconds, all the RFID tags which can be normally read in the cabinet can be read, the speed is high, and the accuracy is high.
As shown in fig. 1, the backend management module is responsible for managing the asset information read by the RFID reader, and usually the backend management module stores the asset information read by the RFID reader in a database, and in the embodiment of the present invention, the backend management module may precisely locate the equipment information inside the cabinet, the remaining space information of the cabinet, the space where no dummy panel is installed in the cabinet, determine the load of the cabinet, the number of dummy panels, or the asset change, and the like, by using the maskable and reproducible characteristics of the position tag and different classifications of the equipment tag, the dummy panel tag, and the cabinet tag. The following description is specifically made of the preferred modes of managing the read asset information by several backend management modules:
1) and determining the residual space of the cabinet.
When the remaining space of the cabinet is determined, the maximum value of the number of all the read plastic false panel tags and the number of all the read position tags can be determined for the cabinet, and the sum of the determined maximum value and the number of all the read metal false panel tags is determined as the remaining space of the cabinet. Can be expressed as follows:
the remaining space of the cabinet is max (the number of sigma plastic false panel labels, the number of sigma position labels) + the number of sigma metal false panel labels.
In the actual calculation process, the specific number of the remaining U of the cabinet can be determined according to the number of the U occupied by the plastic false panel and the metal false panel and the number of the U of the position label.
2) And determining that the false panel space is not installed in the cabinet.
When it is determined that the false panel space is not installed in the cabinet, the maximum value of the number of the read plastic false panel labels and the number of the position labels may be determined for the cabinet, and the difference between the determined maximum value and the number of the plastic false panel labels may be determined as the non-installed false panel space. Can be expressed as follows:
the space where no dummy panel is installed in the cabinet is max (the number of sigma plastic dummy panel labels, the number of sigma position labels) — the number of sigma plastic dummy panel labels.
In addition, according to the corresponding relation between the position label in the cabinet and the label of the false panel, the position where the false panel is not installed can be positioned, and the method can be used for optimizing the air duct of the cabinet and improving the refrigeration efficiency of the cabinet of the elevator.
3) The load of the cabinet is determined.
When the load of the cabinet is determined, the equipment rated power read from each equipment tag can be weighted and summed for the cabinet, the weight of each equipment rated power is the power factor of the corresponding equipment, and the obtained value is the load of the cabinet. Can be expressed as follows:
the rack load is the rated power of device 1 x the power factor of device 1 + the rated power of device 2 x the power factor of device 2 + … + the rated power of device n x the power factor of device n.
Where n is the number of devices already present in the cabinet. The power factor of the device is the ratio of the actual power of the device to the rated power. It should be noted that the rack load determined here is usually the result of an estimation.
4) And positioning equipment information in the cabinet. Through the scanning to equipment label, can pinpoint the equipment information in the cabinet.
The above four kinds of asset management can provide effective data support for cabinet space capacity management, load capacity management, cabinet air duct optimization and the like.
5) And alarming when the assets are changed.
After the asset information of the cabinet is read, the read asset information can be compared with historical asset information, and if the asset information is changed, an alarm can be triggered to prompt an administrator to confirm the changed asset information. The change condition for triggering the alarm can be customized, for example, when the equipment information is changed, the alarm is triggered.
The alarm at the time of change may also be made based on the determination results of the above four asset management, such as an alarm when the cabinet remaining space is below a set threshold, or an alarm when the cabinet load exceeds a set threshold.
It should be noted that, in the system shown in fig. 1, devices used in network communication such as switches, routers, splitters, etc. may also be included, and are not shown in fig. 1 since they are not limited by the present invention. In addition, one RFID reader may also administer multiple cabinets within its reading capability range, and fig. 1 only shows the case of administering one cabinet, and the case of administering multiple cabinets is similar to the case of one cabinet, and is not described again.
The asset information acquiring method corresponding to the system is shown in fig. 3, that is, in step 301, the monitoring unit monitors whether the cabinet door is opened or closed, and if yes, step 302 is executed; otherwise, the step 301 is continuously executed to detect the opening and closing of the cabinet door.
Of course, in addition to the step 301 of triggering the RFID reader to read the RFID tags on the assets of the data center through the antenna by detecting the opening and closing of the cabinet door, other triggering methods, such as manual triggering, periodic triggering, etc., may also be adopted.
In step 302, the monitoring unit triggers an RFID reader to read RFID tags on assets in the data center via the antenna.
Here, the RFID tag of each asset includes a cabinet tag, a location tag, an equipment tag, and a false panel tag. The content and the layout mode of each type of tag and the layout mode of the antenna are described in the system embodiment, and are not described herein again.
In step 303, the RFID reader enters the asset information read from the RFID tag into the back-end management module.
The asset information read by the RFID reader comprises cabinet information, position information, equipment information and false panel information, the read information is transmitted to the rear-end management module, and the rear-end management module stores the information into the database.
In step 304, the back-end management module performs asset management on the asset information read by the RFID reader. The specific asset management method is also described in the system embodiment, and is not described herein again.
As can be seen from the above description, the system and method provided by the embodiment of the present invention can have the following advantages:
1) the asset information is acquired through the RFID technology, no matter the assets are changed, moved and checked, manual intervention is not needed, the asset information can be automatically completed, the accuracy and the efficiency are high, and the maintenance cost is greatly reduced compared with manual maintenance.
2) Only dozens of RFID tags and one or more antennas need to be arranged in the cabinets of the data center, and a plurality of cabinets can share one RFID reader, so that the realization cost is low.
3) The cabinet label, the position label, the false panel label and the equipment label can be pre-installed when leaving a factory, and the local installation is very simple and the delivery is simple.
4) The equipment information in the cabinet can be accurately positioned by reading the equipment tags in the cabinet, the residual space of the cabinet, the installation condition of the false panel, the load of the cabinet and the like can be determined by the position tags and the false panel tags, and data support is provided for asset management, cabinet space capacity management, cabinet load capacity management, cabinet air duct optimization and the like.
5) The RFID label can be read and written, information can be written in according to a uniform format before the RFID label is put into use, the accuracy and the specification are not easy to be falsified by people during reading, and the safety is improved.
6) When the assets are changed, the system can give an alarm in real time, prevent the assets from flowing out and illegal assets from entering into the system, and track the asset transfer process in real time.
