The system has the advantages of strong anti-jamming performance, high reliability, strong flexibility and low power consumption.
Description
Technical field
The utility model relates to a kind of tag system, concrete relates to a kind of ultrahigh frequency tag system.
Background technology
At present, tag system commonly used on the market belongs to passive tag system, does not need battery; The required energy of electromagnetic wave acquisition work by read-write equipment produces still reads close together, one-way communication; Problems such as anti-collision property is bad, and reliability is not high, application limitation is very big.
The utility model content
Not enough for overcoming in the prior art, the utility model aims to provide a kind of strong anti-interference performance that has, high reliability, and dirigibility is strong, ultrahigh frequency tag system low in energy consumption.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is realized through following technical scheme:
A kind of ultrahigh frequency tag system; It comprises through the ultrahigh frequency of the mutual transmission signals of microwave mode seeks words device and ultrahigh frequency label; Said ultrahigh frequency is sought the words device and is comprised that talking about the device controller through seeking of control channel communication talks about the device transceiver with seeking, and said ultrahigh frequency label comprises label controller and the tag transceiver that intercoms mutually through control channel.
A kind of communication means of ultrahigh frequency tag system, it comprises following disposal route: at first, ultrahigh frequency is sought the words device and is received the application system instruction; Then, the words device transceiver of seeking that words device controller seeks the words device through control channel control ultrahigh frequency of seeking that ultrahigh frequency is sought the words device gets into sending mode, sends the data through the specific format of Cyclic Redundancy Code and forward error correction check code; Then, the ultrahigh frequency label receives the data through the specific format of Cyclic Redundancy Code and forward error correction check code of seeking by ultrahigh frequency that the words device sends; At this moment, if label controller test error correction data indicating correct, then the tag transceiver signal of giving notice wakes label controller up under holding state; Behind the label controller working stability; Read correct data through control channel, then, the ultrahigh frequency label sends it back and correctly reads marking signal; Seek the words device by ultrahigh frequency and discern automatically, accomplish an operating process; If label controller test error correction data misdirection, then label controller is still at holding state.
Further, the data of said specific format comprise director data, special identity data, information data, CRC data and forward error correction checking data.
Compared with prior art, the utlity model has following beneficial effect:
The ultrahigh frequency tag system of the utility model has strong anti-interference performance, high reliability, and dirigibility is strong, and is low in energy consumption.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of instructions, below with the preferred embodiment and the conjunction with figs. detailed description of the utility model.The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the ultrahigh frequency tag system of the utility model.
Embodiment
Below with reference to accompanying drawing and combine embodiment, specify the utility model.
Embodiment 1:
Referring to shown in Figure 1; A kind of ultrahigh frequency tag system; It comprises through the ultrahigh frequency of the mutual transmission signals of microwave mode seeks words device 1 and ultrahigh frequency label 2; Said ultrahigh frequency is sought words device 1 and is comprised that talking about device controller 3 through seeking of control channel communication talks about device transceiver 4 with seeking, and said ultrahigh frequency label 2 comprises the label controller 6 and tag transceiver 5 that intercoms mutually through control channel.
Embodiment 2:
Referring to shown in Figure 1, a kind of communication means of ultrahigh frequency tag system, it comprises following disposal route: at first, ultrahigh frequency is sought words device 1 and is received the application system instruction; Then, the words device transceiver 4 of seeking that words device controller 3 seeks words device 1 through control channel control ultrahigh frequency of seeking that ultrahigh frequency is sought words device 1 gets into sending modes, sends the data through the specific format of Cyclic Redundancy Code and forward error correction check code; Then, ultrahigh frequency label 2 receives the data through the specific format of Cyclic Redundancy Code and forward error correction check code of seeking by ultrahigh frequency that words device 1 sends; At this moment, if label controller 2 test error correction data indicating corrects, then tag transceiver 5 signal of giving notice wakes label controller 2 up under holding state; Behind label controller 2 working stabilities; Read correct data through control channel, then, ultrahigh frequency label 2 sends it back and correctly reads marking signal; Seek words device 1 by ultrahigh frequency and discern automatically, accomplish an operating process; If label controller 2 test error correction data misdirections, then label controller 2 is still at holding state.
Further, the data of said specific format comprise director data, special identity data, information data, CRC data and forward error correction checking data.
During the CRC practical application; Dispensing device calculates the cyclic redundancy code value and together sends to receiving trap with data; Receiving trap recomputates Cyclic Redundancy Code to the data of receiving and compares with the Cyclic Redundancy Code of receiving; If two cyclic redundancy code values are different, then mistake appears in the declarative data communication.
The forward error correction verification is a kind of data encoding technique, and error detection is verified by the take over party in the transmission, and in forward error correction mode, receiving end not only can be found mistake, and can confirm the position that binary element makes a mistake, thereby corrects.Forward error correction mode must use error correcting code.
Adopt the verification of above dual mode can effectively get rid of because in data transmission procedure, because the Data Receiving mistake that environmental disturbances produces.
Cyclic Redundancy Code and forward error correction verification all adopt the hardware decoding to realize by the hardware transceiver mode when receiving.And it is whether correct through the transmitting-receiving of notification signal indicating control.Adopt this mode, can let controller idle the time, get into holding state.Can effectively reduce the power consumption of tag system like this.
In the utility model, adopt the ultrahigh frequency tag system of above Mechanism Design can have strong anti-interference performance, high reliability, advantage such as dirigibility is strong, and is low in energy consumption.
The preferred case study on implementation that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
