Description
Technical field
The utility model relates to a kind of rack positioning system, can improve the positioning precision of the RFID label tag on equipment within machine cabinet, thus improves the rack efficiency of management, is a kind of important application of Internet of Things.
Background technology
In the digital machine room of the data centers such as electric power, bank, operator, government, having a large amount of rack, each rack has a lot of data equipment, how to realize the accurate location of the equipment in rack, is realize one of prerequisite that rack effectively manages.
Utility model content
The purpose of this utility model is to provide one can to the pinpoint rack positioning system of cabinet equipment.The technical solution of the utility model is as follows:
A kind of visible ray or infrared rack positioning system, comprise the RFID label tag on the rack offering multiple slot and the equipment being attached to needs management, it is characterized in that, described RFID label tag comprises microprocessor (MCU) and coupled photosensitive device and RFID radio-frequency module; At least one reader is had in rack outer setting, reader comprises CPU and coupled RFID radio-frequency module, communication interface and multiple luminescence unit, the light range of exposures of each luminescence unit of reader is limited in the width range of slot positions of machine cabinet corresponding thereto, and reader is by communication interface and central controller communication; Equipment is placed in after in rack, the RFID label tag that each equipment pastes just to slot positions of machine cabinet, thus just to a luminescence unit of certain reader; Whether the photosensitive device of RFID label tag is lighted for the luminescence unit responding to the reader just right with its position, the electric signal that photosensitive device exports through opto-electronic conversion, generate digital signal through amplifying circuit again, digital signal is admitted to the microprocessor (MCU) of RFID label tag;
Preferably, described luminescence unit is light emitting diode or infrared tube; Described RFID label tag reader carries out communication by network interface, serial ports or wireless communication module and central controller; The communication interface of described RFID reader is 485 communication interfaces.
Photosensitive device in optical alignment and RFID label tag combines by the utility model, and the relation one to one between the equipment utilizing the needs in the luminescence unit of reader and rack to locate, achieves the accurate location to cabinet equipment.
Accompanying drawing explanation
Fig. 1 is the application scenarios of rack positioning system of the present utility model, i.e. the one-piece construction schematic diagram of Cabinet administration system;
Fig. 2 is RFID label tag composition frame chart;
Fig. 3 is reader composition frame chart.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described.
Rack positioning system of the present utility model specifically comprises: rear portion is with the rack of multiple slot, the RFID label be attached on equipment, multiple stage reader device.Its application scenarios is Cabinet administration system, as shown in Figure 1.Fig. 1 does not only disclose the annexation between RFID label tag and reader, further discloses the connection between both and central controller and networking mode.The structure of equipment RFID label tag and reader respectively as shown in Figures 2 and 3.
As Fig. 2, equipment RFID label tag is attached to above equipment, is active RFID tag, comprises microprocessor (MCU), photosensitive device and the RFID radio-frequency module of the status information of the equipment of storing.Photosensitive device wherein can be infrared tube, photodiode or phototriode; RFID radio-frequency module can be 433M chip, also can be 800 ~ 900M UHF chip; Also can be 2.45G chip.The RFID label tag that the present embodiment adopts is active label, also can adopt passive label.
As Fig. 3, reader is used to the equipment reading FRID label information, and it is formed primarily of microprocessor (MCU), multiple luminescence unit, RFID radio-frequency module and Bus Interface Unit, is be connected by 485 buses between each reader device.Each luminescence unit can be light emitting diode or infrared tube.The slot of rack and luminescence unit are relations one to one, and after equipment is put into rack, the RFID label tag be attached on equipment should correspond to a luminescence unit of certain reader.The optical radiation angle limits of each luminescence unit, within the scope of one, to ensure the width only covering a slot, thus realizes the accurate location of equipment RFID label tag.
The principle of work of positioning system of the present utility model is: on each data equipment of rack, paste a RFID label tag, RFID label tag contains photosensitive device; RFID reader has luminescence unit, and the light range of exposures of luminescence unit is limited in the width of a slot, ensures to only have the photosensitive device of the RFID label tag of this slot to be triggered; Each rack deploy many groups RFID reader and a central controller; Cascade is carried out by RS485 bus between multiple RFID reader and central controller.
When carrying out the equipment location on certain slot, light emitting diode corresponding with this slot on reader is luminous, photosensitive device in RFID label tag is triggered, the electric signal that photosensitive device exports through opto-electronic conversion, digital signal is generated again through amplifying circuit, this digital signal and positioning signal, digital signal is admitted to the microprocessor of RFID label tag, thus realizes location.
Claims (2)
1. a visible ray or infrared rack positioning system, comprise the RFID label tag on the rack offering multiple slot and the equipment being attached to needs management, it is characterized in that, described RFID label tag comprises microprocessor (MCU) and coupled photosensitive device and RFID radio-frequency module; At least one reader is had in rack outer setting, reader comprises CPU and coupled RFID radio-frequency module, communication interface and multiple luminescence unit, the light range of exposures of each luminescence unit of reader is limited in the width range of slot positions of machine cabinet corresponding thereto, and reader is by communication interface and central controller communication; Equipment is placed in after in rack, the RFID label tag that each equipment pastes just to slot positions of machine cabinet, thus just to a luminescence unit of certain reader; Whether the photosensitive device of RFID label tag is lighted for the luminescence unit responding to the reader just right with its position, the electric signal that photosensitive device exports through opto-electronic conversion, generate digital signal through amplifying circuit again, digital signal is admitted to the microprocessor (MCU) of RFID label tag.
