Description
Technical field
The present invention relates to a kind of electronic tag, is specifically a kind of compound multi-frequency electronic tag.
Background technology
Electronic tag (RFID), as a kind of usual way of radio communication, is all widely applied in many fields such as mobile management, attendance management, gate control system and occasion.In principle of work, can be divided into active electronic label and passive electronic label.Active electronic label needs battery to power, feature be read distance, read and write effective, but because battery life is limited, when be applied to magnanimity terminal (as the automobile in perform region reach tens or millions of) time, change battery and will cause very burden, and can the obvious performance that affects system.Passive electronic label does not need powered battery, thereby has without changing the distinguishing feature of power supply and maintenance-free and have advantage, but it is relatively near to read distance, and read-write effect and distance are all the very large defects of himself not as good as active label.Electronic tag is in the market that active label or passive label are used separately mostly, can not meet system requirements to a great extent, and systemic-function is had a greatly reduced quality.
Summary of the invention
The invention provides a kind of compound multi-frequency electronic tag, when integrating active electronic label and passive electronic label, can also further to the information in electronic tag, carry out effective security fence.
Compound multi-frequency electronic tag of the present invention, its basic structure is to have the passive electronic label that is provided with wafer and microstrip antenna on substrate simultaneously, and the active electronic label of being powered by battery unit.Wherein, in feed circuit between active electronic label and battery unit, at least should include and be arranged on the on-chip conductive structure of passive electronic label, that is, making at least should have one section to need through passive electronic label substrate in the feed circuit between active electronic label and battery unit.
Because the substrate of passive electronic label normally has the materials such as substrate hard, crisp feature with pottery etc., make, therefore when being subject to mandatory External Force Acting, fragile rhegma is bad.A part in the necessary conducting channel of active electronic label work is arranged on this passive electronic label substrate, once this compound multi-frequency electronic tag, the sled by force that particularly passive electronic label is wherein subject to improper external force get damaged after, the feed circuit of active electronic label also can not work on thereupon cutting off, and reach the anti-effect of usurping.For this reason, on above-mentioned compound multi-frequency electronic tag basis, the position that at least can also be provided with said conductive structure in passive electronic label substrate is provided with the easy slight crack mark of pick-proof, and further to improve, it is tamper-proof/ability usurped.
In above-mentioned compound multi-frequency electronic tag, be understandable that, for avoid interacting of two types of electronic tags as far as possible, said on-chip this conductive structure of passive electronic label that is arranged on, optimal way is arranged on the substrate edge blank space of avoiding passive electronic label microstrip antenna.
As a same reason, for avoid issuable between two types of electronic tags as far as possible, interact or disturb, a kind of optimal way of two electron-like labels, to make active electronic label independently be arranged on respectively in non-contacting parallel plane structure and (comprise and be divided into different independent bottom plate structures from the substrate of passive electronic label, or be located at the different modes such as not ipsilateral of same base arrangement), active electronic label and battery unit thereof are with wafer in passive electronic label and microstrip antenna does not contact and its plane projection non-overlapping.On this basis, can in conjunction with the further preferred arrangement adopting, comprise separately or arbitrarily:
The both sides that active electronic label and battery unit thereof are located at respectively to wafer plane projected position in passive electronic label, make the spatial arrangement of components and parts on base plate more abundant, reasonable and balanced;
Active electronic label and the substrate of passive electronic label are separately positioned on the phase tool back plane of same base plate; And/or
Active electronic label and battery unit thereof are separately positioned on other supporting structure outside base plate and base plate.For example, battery unit can be embedded to the respective battery base medium form at the structure/position of the battery altering operation of being more convenient for.
On the basis of said structure; the further advantageous measure that can also take is, and the above-mentioned conductive structure that is arranged in feed circuit between the on-chip active electronic label of passive electronic label and its battery unit is in parallel and is also provided with standby warning/holding circuit structure.
Said standby warning/holding circuit structure, can preferably adopt comprising as transistor switching circuit, monostable circuit, bistable circuit of at present existing bibliographical information and/or use, or the mature technologies such as unitized construction and the mode of electronic circuit and relay.Be provided with after warning/holding circuit structure, once improper sled occurs to be got and makes passive electronic label damaged substrate and caused cutting off after the working power of active electronic label, this warning/holding circuit structure can be by the start battery of active electronic label, (this action conventionally has or can artificially to preset certain hour poor), by this warning/holding circuit structure, to active electronic label, continue power supply, and can and/or send warning message to monitor control mechanism by this improper interrupting information (being that passive label is damaged) record, by monitor control mechanism and/or by the program arranging in active electronic label, the safety of information in label is carried out to protectiveness subsequent treatment, for example according to circumstances select the work that do not wake up, information auto-erasing, the operations such as format, make it not reproducible, effectively to protect the data security of electronic tag.
Be appreciated that thus; the compound multi-frequency electronic tag of the above-mentioned form of the present invention; integrate active electronic label and passive electronic label; not only avoided to greatest extent current active electronic label and passive electronic label defect and deficiency separately; and can bring into play more fully the Comprehensive Characteristics of the two mutual supplement with each other's advantages, and can when being subject to improper destruction, can to monitor control mechanism, send in time and report to the police and take further the information in effective protection electronic tag, the measure of data security.
Embodiment by the following examples, is described in further detail foregoing of the present invention again.But this should be interpreted as to the scope of the above-mentioned theme of the present invention only limits to following example.Without departing from the idea case in the present invention described above, various replacements or the change according to ordinary skill knowledge and customary means, made, all should comprise within the scope of the invention.
