Description
Technical field
The utility model relates to technical field of RFID, particularly relates to a kind of new-type high-frequency RF ID read-write equipment.
Background technology
In purifier, often a purifier needs to use multiple filter core, and each filter core is because effectiveness is different, and its serviceable life is also different, so replacing construction is also different.After filter core reaches the time limit in serviceable life, purifier needs reminding user to replace filter core, so equipment needs the service time of reading the filter core recorded in the electronic tag on filter core.If adopt traditional man-to-man mode, need to be equipped with multiple read head to read the data in corresponding electronic tag respectively in an equipment, but this is in actual design, can increase cost, and the volume of increasing circuit plate.
Electronic tag is fixed on cartridge surface, and electronic tag possesses memory function, and definition has one No. ID.The authorization information of the legal filter core of producer's definition is comprised in described ID.Water purifier water inlet pipe place is provided with water level switch, calculates discharge.The life-span of filter core is relevant to the discharge passed through, and can define the life-span of filter core with Water usage.And in same water purifier, the serviceable life of the filter core of different function is different, so the time changed is also different.For ensureing the legitimacy of purifying water effect and filter core, other filter cores are on the market avoided to pretend to be legal filter core, when product uses first, master control borad is verified filter core ID by read head and antenna, if legal filter core, then by checking, machine normally works, if not legal filter core, then can not work; Water usage is written in the chip of filter core by read-write equipment, and filter core chip stores water flow data, when reaching the serviceable life of definition, then machine can show corresponding prompting, the corresponding filter core of reminding user to replace.When product energising or more renew cartridge time, need to read serviceable life of filter core, i.e. Water usage, to judge the remaining life of filter core.When filter core is put on different machines, also need the legitimacy first verifying filter core, and then read the serviceable life of filter core.
In addition, for existing RFID read-write device, it also exists can not ensure the reading consistance of distance and the defect of stability.
Utility model content
The purpose of this utility model is to provide a kind of new-type high-frequency RF ID read-write equipment for the deficiencies in the prior art, and this new-type high-frequency RF ID read-write equipment is novel in design, structure is simple, cheap, usability is strong, simple to operate, reading/writing distance good stability and consistance is strong.

Wherein, the model of each described electromagnetic relay is respectively HK23F-DC5V-SH6.
The beneficial effects of the utility model are: the new-type high-frequency RF ID read-write equipment of one described in the utility model, it includes MCU controller, read head and at least two respectively from different electronic tag antenna one to one, read head is electrically connected with MCU controller by connection line, each antenna is electrically connected with read head respectively by connection line, each antenna is equiped with to the connection line between read head the electromagnetic relay controlling corresponding connection line break-make respectively, each electromagnetic relay is electrically connected with MCU controller respectively by connection line, each antenna adopts 13.56MHZ high-frequency work frequency respectively.Designed by said structure, the utility model have modern design, structure is simple, cheap, usability is strong, simple to operate, reading/writing distance good stability and the strong advantage of consistance.
Accompanying drawing explanation
Utilize accompanying drawing to be further detailed the utility model below, but the embodiment in accompanying drawing is not formed any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
Include in FIG:
1---MCU controller
2---read head
3---antenna
4---electromagnetic relay.
Embodiment
Below in conjunction with concrete embodiment, the utility model is described.
As shown in Figure 1, a kind of new-type high-frequency RF ID read-write equipment, include MCU controller 1, read head 2 and at least two respectively from different electronic tag antenna 3 one to one, read head 2 is electrically connected with MCU controller 1 by connection line, each antenna 3 is electrically connected with read head 2 respectively by connection line, each antenna 3 is equiped with to the connection line between read head 2 electromagnetic relay 4 controlling corresponding connection line break-make respectively, each electromagnetic relay 4 is electrically connected with MCU controller 1 respectively by connection line, and each antenna 3 adopts 13.56MHZ high-frequency work frequency respectively.
Wherein, the model of each electromagnetic relay 4 is respectively HK23F-DC5V-SH6.
Need point out further, the utility model adopts electromagnetic relay 4 to switch different antennas 3 as change-over switch, a corresponding antenna 3 of electromagnetic relay 4, when which electronic tag needs read, only need to pass through control command, corresponding electromagnetic relay 4 is energized closed, the antenna 3 that gating is corresponding, just can read the electronic tag corresponding with it; Wherein, electronic tag is fixed on the filter core of water purifier and is attached to cartridge surface.
In utility model works process, send corresponding steering order by MCU controller 1, corresponding electromagnetic relay 4 is energized adhesive, with the antenna 3 that gating is corresponding, read electronic tag corresponding with it; Wherein, steering order is sent by MCU controller 1, and electromagnetic relay 4 and read head 2 are connected on the I/O port of MCU controller 1, by computer program, makes the level of I/O port change the adhesive or the disconnection that control corresponding electromagnetic relay 4.Need point out further, each electromagnetic relay 4 of the present utility model is normally opened relay, during work, and energising adhesive.The utility model is controlled by MCU controller 1 pair of electromagnetic relay 4, to make electromagnetic relay 4 closed and disconnected, and the same time only can close a road electromagnetic relay 4, when electromagnetic relay 4 closes, Ji Zhe road antenna 3 has been switched to read head 2, can read and write this road electronic tag, if need the electronic tag reading and writing other road, only need control the closed of corresponding electromagnetic relay 4 carries out switched path.
