Embodiment

Embodiment one:

Present embodiment is a kind of pinpoint electronic label device that has, as shown in Figure 1, comprise: be suspended on the electronic tag 6 on the container door lock hole, with the read write line 3 on the passage that container passes through of being installed in of electronic tag dedicated radio link, utilize number information and the steady arm 2 that carries out dedicated radio link of the electronic tag in the efficient working range of self.

The basic ideas of present embodiment are to use a kind of simple radio receiver-transmitter, its number information is written to by near the electronic tag it, because this coding is unique, therefore can show this position, after making the information of read write line in reading tag, can obtain this coded message accurately, so obtain this electronic tag the position of process.Using this simple method can effectively distinguish in the caused position that transmits and receives in the scope of a plurality of read write lines and a plurality of electronic tags obscures.

Present embodiment is to have three read write line A ₁, A ₂, A ₃With three electronic tag C ₁, C ₂, C ₃And three steady arm B ₁, B ₂, B ₃Situation describe, see Fig. 1.The working range 1 of each steady arm is respectively b ₂, b ₂, b ₃Three read write line A ₁, A ₂, A ₃ Working range 4 are a ₁, a ₂, a ₃, covered three passages that the container that electronic tag indicated passes through.Any one container that has electronic tag enters this zone, all can carry out exchanges data with three read write lines, and perhaps exchanges data also all can be carried out with this read write line in three electronic tags zone of entering any one read write line.If there is not steady arm, the transmission of data will confusion reigned, produces mass of redundancy data to I haven't seen you for ages, takies too much hardware and software resource, reduces work efficiency.In another problem of container industry is that container is that sheet metal by a large amount of reflection electromagnetic waves constitutes, too much data transmission has increased the time of single exchanges data, make wireless signal between sheet metal, come back reflective, the serious transmission of disturbing normal signal is so the weak point that should try one's best of the time of exchanges data is for well.

The course of work of present embodiment is such: when electronic tag entered the working range of read write line, read write line was not handled label; Have only electronic tag to enter into the working range of certain steady arm, steady arm just can be written to the number information of oneself in the electronic tag, and read write line can parse this coding corresponding position information after finding in the label coded message of steady arm has been arranged.At this moment.The read write line information of reading tag more just is valid data.Electronic tag C for example ₁Path of travel be c ₁, at c ₁The path on will be by three read write lines working range a ₁, a ₂, a ₃, have only C ₁Arrive steady arm B ₃Working range b ₃, B ₃Just the coded message of oneself can be written to label C ₁In.After this moment, any read write line can find had coded message in the label, will resolve the pairing positional information of this coded message, thereby judge the path of travel of this label.

The another kind of course of work is: three electronic tags enter the working range of a read write line, have only one of them electronic tag by behind certain steady arm, and this steady arm can be written to the coded message of oneself in the label.After this moment, any read write line can find had coded message in the label, will resolve the pairing positional information of this coded message, thereby judge the path of travel of this label.For example three electronic tag C1, C2, C3 wherein have only C2 to pass through the perform region b2 of B2, so have only that B2 can be written to the coded message of oneself in the label C 2, after read write line found that the coded message of B2 is arranged in the label, pass through near the B2 thereby can judge C2.

Embodiment two:

Present embodiment is the refinement of embodiment one, and the passage that described container 8 passes through is the container hanging district that a plurality of allocation and transportation equipment 7 are installed, and described steady arm is installed in the two ends of the suspender 9 of each allocation and transportation equipment.

Usually there be in a row being installed in of allocation and transportation equipment of many allocation and transportation containers to transport on the porte-cochere of container at the harbour, just on the path of travel of electronic tag, as shown in Figure 2.

In Fig. 2, steady arm is installed in the two ends of the suspender of container allocation and transportation equipment, and read write line is installed on the handling appliance.Electronic tag is installed on the lockhole of container chamber door.When container and electronic tag by near the handling appliance time, read write line can be found this label.But because the working range that electronic tag does not enter steady arm, so read write line can not done any processing to electronic tag.When container was sling by suspender, electronic tag entered the effective range of steady arm work, and steady arm will be written to positional information in the electronic tag.At this moment, read write line just can identify the container that has adhered to this electronic tag and sling by suspender.

Electronic tag for hoisting area work, though on each allocation and transportation equipment, read write line is installed, but when the container that have an electronic tag by a plurality of allocation and transportation equipment the time, the read write line on each allocation and transportation equipment all can be read the container information that passes through, and so ten minutes is easy to generate confusion.

Embodiment three:

Present embodiment is the refinement of embodiment one, and the passage that described container passes through is that the container pool that is provided with a plurality of vehicle haul roads is imported and exported, and described steady arm is installed on each vehicle haul road.

Shown in Figure 3 is import and export 10 vertical views of a container pool vehicle, and its shape is similar to the charge station of highway, and the vehicle turnover of the road junction in many tracks for delivery container arranged.Present embodiment uses a read write line that all road junctions are monitored.On the lockhole of electronic tag attached to the chamber door of container, can play the effect of pinning chamber door, steady arm is installed in the next door in every track at road junction.When container from the road junction through out-of-date, pass through the steady arm overlay area simultaneously attached to the electronic tag on the container.Steady arm records positional information (lane information of sign) in the label automatically.Read write line can be read and write all electronic tags that passes through arbitrary track.When label passes through, positional information (lane information of sign), EDI information and switch record in the read write line meeting reading tag.

Compare and do not use steady arm in traditional solution, read write line can only obtain the whether information by the road junction of electronic tag.Know the lane information that electronic tag passes through if desired, need all place read write line in every track.Such scheme not only cost is huge, and because interfering with each other between the read write line, reliability can not get guaranteeing.
