Description
Technical field
The present invention relates to board electronic tag administrative skill field, more specifically, the present invention relates to a kind of read-write control system and method for board electronic tag.
Background technology
The veneer manufacturing information is unique retrospective sign in the veneer Life cycle as " I.D. " of veneer.Utilization veneer manufacturing information can promote the maintenance cost and the handling cost of installation, manageability and the product lifecycle of product, for example: reprocess at original paper, the efficient making of follow-up of quality, device's document and the supporting role that the aspect such as refreshes.The manufacturing information of described veneer is stored with the form of electronic tag, simple to operate by the management of electronic tag being realized management to veneer, therefore more and more be subject to people's attention.
With reference to figure 1, this figure is the schematic flow sheet that prior art reads board electronic tag information, in this method controlled veneer for have central processing unit (this method specifically comprises for Center Process Unit, veneer CPU):
Step 1, the message of the controlled board electronic tag information of master control borad structure acquisition request;
Step 2, master control borad sends the described request message by data channel to controlled veneer;
Step 3, the Be Controlled veneer is resolved the described request message from master control borad;
Step 4 reads electronic labeling information in this one-board memory according to the request message after the described parsing;
Step 5, controlled veneer carry the message of described electronic labeling information to the master control borad feedback;
Step 6, master control borad parse described electronic tag after receiving this message from described this message, and described electronic labeling information is sent.
In addition, also be included in the above-mentioned steps when not having message packet to transmit, need regularly to transmit some handshake information on data channel, it is normal can monitoring this service channel with the CPU that guarantees two ends, and described two ends are controlled veneer end and master control borad end.
Controlled veneer is the veneer that has CPU in the above-mentioned prior art, but in realizing application, for example company need manage the goods that sends, for the veneer that has CPU, increase this electronic tag function, only need to increase a kind of control message, deposit in the storer information such as time limit for dispatch passable, but some veneer is the veneer that does not have CPU, if will not have the read-write of the board electronic tag of CPU by existing techniques in realizing, then need to increase the service channel of CPU and transmission message, increased cost for this veneer.
To sum up, though above-mentioned prior art can realize the management of board electronic tag, be stored in following defective:
Because the form of available technology adopting message transmits board electronic tag information, need CPU that message is handled, the bearer path of message also is absolutely necessary simultaneously, for the veneer that does not have CPU, then need to increase the bearer path of CPU and message, therefore increased cost.
