Abstract
The invention relates to a dual-frequency electronic tag reading and writing module for fire control. The module comprises an interface, a control chip, a 2.4GHz radio frequency chip, a 13.56G radio frequency chip, a 2.4GHz antenna and a 13.56MHz antenna, wherein the output end of the control chip is connected with the input end of the 13.56MHz radio frequency chip through a parallel port, the output end of the 13.56MHz radio frequency chip, the output end of the control chip is connected with the 2.4GHz radio frequency chip through a serial interface, the output end of the 2.4GHz radio frequency chip is connected with the 2.4GHz antenna, and the control chip is connected with an upper computer through an interface. According to the dual-frequency electronic tag reading and writing module, various 13.56MHz electronic tags can be read, and a 2.4GHz active electronic tag can be read. The dual-frequency electronic tag reading and writing module is matched with a 13.56MHz and 2.4GHz dual-frequency semi-active electronic tag for use, thus the problems of read distance and directionality of the tag can be effectively overcome.
Description
Technical field
The present invention relates to a kind of fire power subtab module for reading and writing, relate in particular to a kind of fire-fighting double-frequency electronic label module for reading and writing.
Background technology
Electronic tag generally all is fixed on the object, label need be moved to during read-write in the electromagnetic field scope of read write line formation, and label could effectively be distinguished.Therefore the electronic tag canned data all needs read write line to operate, so simultaneously because the reading/writing distance that needs carrier wave to activate between read write line and label is also restricted.And the active electronic label of 2.4G adopts self-powered, and it reads distance generally can reach 50-100 rice, and there is directional problems in active label, though read label but can't know its particular location.
The management of fire-fighting article, there is article placement location circumstance complication, simultaneously the big problem of quantity is placed in the specific region, thus need a kind ofly can search many labels fast and read, again can pinpoint dedicated RF ID label and the read-write machine dedicated module that reads this class label.
Summary of the invention
The object of the present invention is to provide a kind of fire-fighting double-frequency electronic label module for reading and writing.Both support to read the high-frequency electronic label of 13.56MHz, can realize reading the aggregate of 2.4GHz active label again, solved the distance problem of 13.56MHz passive label and the directional problems of 2.4GHz label.
The fire-fighting double-frequency electronic label module for reading and writing that the present invention proposes, by interface 1, control chip 2,2.4GHz radio frequency chip 3,13.56MHz radio frequency chip 4,2.4GHz antenna 5 and 13.56MHz antenna 6 are formed, wherein: the output terminal of control chip 2 connects the input end of 13.56MHz radio frequency chip 4 by the parallel port, 13.56MHz the output terminal of radio frequency chip 4 connects 13.56MHz antenna 6, the output terminal of control chip 2 connects 2.4GHz radio frequency chip 3 by serial line interface, 2.4GHz the output terminal of radio frequency chip 3 connects 2.4GHz antenna 5, control chip 2 connects host computer by interface 1.
The present invention can read the electronic tag of various 13.56MHz.Can read simultaneously the active electronic label of 2.4GHz again.Use at double frequency half active electronic label that cooperates a 13.56MHz and 2.4GHz, what can effectively overcome label reads distance problem and directional problems.
Beneficial effect of the present invention is: the different needs that can satisfy different occasions in the fire-fighting Item Management.Under control chip control, realize the stack of two frequency ranges of RFID, the label of read-write 13.56MHz and two kinds of frequency ranges of 2.4GHz.According to the actual requirements, manage the fire-fighting Item Information better, wherein the microwave of double frequency module for reading and writing is distinguished frequently in fire-fighting responding strength statistics, fire-fighting and is used in the article checking after the war; And the high frequency region of double frequency module for reading and writing mainly uses aspects such as obtaining essential information, check fire-fighting article parameter when the daily management of fire-fighting article, maintenance, maintenance.
