Description

A kind of smart electronics label for bank's money case

Technical field

The utility model relates to finance escort management domain, especially a kind of smart electronics label for bank's money case.

Background technology

Along with the fast development of China's economy, financial institution's such as bank vault all to relate to the work that buckets of cash goes out warehouse-in every day, thus need to use the escort personnel of special armoured van, money case and specialty to carry out cash transport, simultaneously due to the development of security industry in this year, the units such as increasing enterprise, trade company are also increasing to the demand of this type of security business.At present, existing money case is divided into intelligence and non intelligent two kinds, wherein intelligent money case is accompanied with RFID chip, can preserve information such as switch box records, by RFID read-write equipment, information reading is carried out to it again, can know the information such as the switch box record of money case, the handing-over circulation process for reconcile amounts case carries out following the trail of and monitoring.But this RFID chip adopts the technical scheme of passive ultra-high frequency usually, because ultrahigh frequency microwave is easily affected by environment, antijamming capability is weak, thus easily the situations such as error in data occurs; And its antenna has certain directivity, passive ultra-high frequency RFID chip is needed to be attached to casing outside, if and this passive ultra-high frequency RFID chip is placed in box house, because ultrahigh frequency single deck tape-recorder read or write speed is too fast, then when carrying out batch scanning by RFID read-write equipment, very easily there is the problem of drain sweep, make to need after scanning again manually to check, thus strongly limit accuracy and the efficiency of scanning.

Utility model content

For the problems referred to above of the prior art, the utility model proposes a kind of smart electronics label for bank's money case.

The technical solution of the utility model is: comprise microcontroller, battery, RFID module, storer and peripheral circuit, wherein: described battery, RFID module, storer, peripheral circuit are connected with microcontroller respectively, described microcontroller has unique sequence numbers, and described storer is for storing information and cryptographic algorithm;

Described RFID module comprises microwave communication circuit, microwave radio antenna, low frequency activation circuit, low-frequency antenna, wherein said microwave communication circuit is connected with microcontroller respectively with low frequency activation circuit, described microwave radio antenna is connected by microwave communication circuit, and described microwave radio antenna and microwave communication circuit are for realizing the exchanges data between microcontroller and external unit; Described low-frequency antenna is connected with low frequency activation circuit, and described low-frequency antenna is for receiving low frequency activation signal and by low frequency activation circuit transmission to microcontroller.

Further, described low-frequency antenna is low frequency 3D antenna.

Principle of the present utility model is: adopt the mode that low frequency activation combines with microwave communication, electronic label is in dormant state in idle, just can wake up when only receiving the low frequency activation signal that exterior read-write equipment sends, communicated with exterior read-write equipment by microwave after electronic label is waken up, and carry out certification by cryptographic algorithm, beginning exchanges data after certification is passed through, after completing exchanges data, electronic label enters dormant state again.

Compared with prior art, the beneficial effects of the utility model are:

1. the utility model is in dormant state due to the most of the time, and thus energy consumption is extremely low, built-in battery lasts work more than 3 years;

2. the utility model is by double frequency pattern, only after by low frequency activation, just carries out exchanges data by microwave, effectively prevent extraneous electromagnetic interference (EMI), avoid the situation of loss of data; Solve the too fast and leakage card problem that produces of conventional ultra high frequently single deck tape-recorder read-write simultaneously, ensure that the accuracy of Card Reader and the efficiency of handing-over.

Accompanying drawing explanation

Fig. 1 is system architecture diagram of the present utility model.

Embodiment

Below in conjunction with drawings and Examples, the technical scheme in the utility model is further illustrated.

As shown in Figure 1, the utility model comprises microcontroller, battery, RFID module, storer and peripheral circuit, wherein: described battery, RFID module, storer, peripheral circuit are connected with microcontroller respectively, described microcontroller has unique sequence numbers, and described storer is for storing information and cryptographic algorithm;

Described RFID module comprises microwave communication circuit, microwave radio antenna, low frequency activation circuit, low frequency 3D antenna, wherein said microwave communication circuit is connected with microcontroller respectively with low frequency activation circuit, described microwave radio antenna is connected by microwave communication circuit, and described microwave radio antenna and microwave communication circuit are for realizing the exchanges data between microcontroller and external unit; Described low frequency 3D antenna is connected with low frequency activation circuit, and described low frequency 3D antenna is for receiving low frequency activation signal and by low frequency activation circuit transmission to microcontroller.

The utility model, by double frequency pattern, only just carries out exchanges data by microwave, effectively prevent extraneous electromagnetic interference (EMI), avoid the situation of loss of data after by low frequency activation; Solve the too fast and leakage card problem that produces of conventional ultra high frequently single deck tape-recorder read-write simultaneously, ensure that the accuracy of Card Reader.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
