The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Embodiment as shown in Figure 1, a kind of liquid quantitative receiving vessel, its main body is a water tumbler 1, the water tumbler wall 11 of water tumbler 1 has the antenna 12 and the IC chip 13 of two ring-types, antenna 12 and IC chip 13 are connected by metallic circuit, and above-mentioned antenna 12 and IC chip 13 embed fully to there is no in the wall of container and expose.

As shown in Figure 2 be and the matching used liquid quantitative feed system of the foregoing description, comprise water dispenser 2, bucket 3, frequency read/write 4 and water tumbler 1, described bucket 3 is positioned at the top of water dispenser 2, described frequency read/write 4 is fixedly mounted near the liquid outlet of water dispenser 2, and water tumbler 1 and water dispenser 2 structurally are separated into independent parts separately.

The chip 13 of above-mentioned water tumbler 1 is selected the Mifare card of PHILIPS company for use.Its frequency of operation is 13.6MHz, storage content is that 1KB divides 16 districts, every district 2 cover passwords, the storage area in each district is separate, according to needs of the present utility model, storage area is divided into system region (CDF) and user area (ADF) two districts by function, and wherein system region is by maker and system development merchant and issuer's use of this water tumbler 1, and the user area is used to deposit the relevant data information of holding this liquid container people.

As shown in Figure 3, the principle of the frequency read/write 4 of the foregoing description has mainly been used read-write process chip--the MMM micromodule of 1 Mifare card special use in the frequency read/write 4.It is the core devices that a small-sized maximum operating distance reaches the Mifare read/write device of 20～30mm, and its function comprises modulation, demodulation, generation radiofrequency signal, safety management and anticollision mechanism.Inner structure is divided into radio-frequency region and interface area: radio-frequency region includes modem and power-supplying circuit, directly with a day wire joint; Interface area has the port that links to each other with micro controller system, also have the receipts that link to each other with radio-frequency region/send out device, 16 bytes data buffer, deposit 64 pairs of transmission security keys ROM, deposit the write only memory of 3 cover keys and carry out confirming for three times and the cipher machine of data encryption, anticollision module and the control unit that anticollision is handled.This is a nucleus module of realizing radio communication with radio-frequency card, also is the key interface chip of read write line read-write Mifare card.During read write line work, constantly outwards send the electromagnetic wave (13.6MHz) of one group of fixed frequency, when water tumbler 1 near the time, IC chip 13 in the water tumbler 1 and antenna 12 constitute a LC resonance circuit, its frequency is identical with the transmitting frequency of frequency read/write 4, under electromagnetic excitation, the LC resonance circuit produces resonance like this, thereby makes the electric capacity charging that electric charge arranged.At this electric capacity other end, be connected to the electronic pump of a unilateral conduction, the electric charge in the electric capacity is delivered to another capacitor memory storage.When charge of a capacitor reached 2V, this electric capacity just provided operating voltage as power supply for other circuit on the card, and data and the preservation that read write line sends gone out or received to data transmission in the card.
