Description

The present invention relates to a moving object automatic identification system suitable for production control of various products and operation control of vehicles and the like.

[Conventional technology and its problems]

Recently, a mobile radio transceiver having at least a transmitting unit, a receiving unit and a storage unit is attached to a moving object so that various data can be transmitted and received between the radio transceiver and a radio transceiver on the ground. An automatic identification system for a moving object has been developed in which a receiver can transmit a self-identification signal of the moving object having at least the receiver.

In the above system, the identification device as a terrestrial radio transmitter / receiver is configured, for example, as an identification device (1) as shown in FIG. 4, which includes a control unit (2) and a transmission / reception unit (3). ) And an antenna (4), the transmitting / receiving unit (3) includes a receiving unit for mainly receiving a self-identification signal from the mobile radio transceiver side, that is, the tag box (5) side, and the mobile radio transceiver (5). ) Is integrated with a transmission unit for writing information in the storage unit or for transmitting a signal for rewriting information, and this transmission unit is further written in the mobile radio transceiver (5). An identification device (1) including an input part for sending a signal and integrating these parts is very expensive.

Therefore, it is conceivable to provide a plurality of antennas in order to identify a plurality of moving objects with this one identification device.
In order to identify each moving object with each of these antennas, there is a communication restriction on the distance between these moving objects and each antenna, and it is not possible for multiple antennas to identify separate moving objects simultaneously. This is not possible if the processing units in are common. Further, if this processing device is provided in one identification device according to the number of moving objects to be identified, it becomes even more expensive.

〔Example〕

Hereinafter, a system for identifying a moving object according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 shows the first embodiment and shows the case of application in production control. In the drawing, a tag box (11) is attached to a pallet (10).

In such a pallet (10), necessary data is written at the position A by the identification devices (12) and (13) for transmission and reception. Then, the pallet (10) is moved in the direction of the arrow so that the object (16) is placed at the B position and another object (17) is placed at the C position. At each position A, B and C, the identification devices (13) (14) (15) for reception are arranged in close proximity, but these are the tag boxes attached to the pallet (10) at each position. It receives the self-identification signal from (11). Receiving identification devices (13) (14)
(15) is configured as shown in FIG.
8) and a reception control section (19), and a connector (21) is drawn out between them. Although not shown, the reception control section (19) generates a signal for operating an actuator corresponding to the pallet (10). In addition, the transmitter / receiver (1
The antenna (20) is attached to 8), and the trigger signal is transmitted from this. That is, the receiving identification devices (13), (14) and (15) have only a transmitting function for transmitting a trigger signal, and mainly have a receiving function. Receiving identification device (13) (14)
The tag box (11), which receives the trigger signal from the antenna (20) of (15), makes the data written in its storage unit close to each other at the positions A, B and C (1).
3) (14) (15). Tag box (11) in each receiving identification device (13) (14) (15)
The reception control unit (19) processes the data received from the device. For example, it is confirmed that the pallet (10), which is not shown, has arrived at the B position.
Then, after confirming that a predetermined object is placed, a signal for instructing to move to the next position (that is, a drive signal for the actuator) is generated. At the C position, the object (17) is placed, but the same as above. The position A is the initial position, and the necessary data is written here. This is the identification device for transmission (12).
This is mainly done by the transmission control unit (23) and the connector (22) connected to it, as shown in FIG. 3, and is used for receiving when necessary data is written in the tag box (11). Also, the connectors (21) and (22) of the transmission identifying devices (12) and (13) are coupled to each other, and the antenna (20) is commonly used. Transmission control unit (23)
Although not shown in the figure, the input device is also included. This input device includes, for example, a ten-key pad and a display unit, and the operator transmits necessary data to the tag box (11) through the antenna (20) by the input device and writes it in the storage unit. After writing the necessary data, the connector (2) of the receiving identification device (13) and the transmission identification device (12)
1) and (22) are separated. Identification device for each reception (13) (1
4) (15) also has a connector, but if there is a need, bring the transmitting identification device (12) to this position and connect the connectors (21) (22). Write the necessary data at that time.

The embodiment when applied to the production control according to the first embodiment of the present invention is configured and operates as described above, but in the prior art, the receiving identifying device and the transmitting identifying device were integrated, which is extremely difficult. Although it was expensive, the present embodiment can separate the transmission and the reception and combine them to reduce the cost of the entire system, and still have the same effect as the conventional one. Can be done.

FIG. 2 shows a second embodiment of the present invention, which is applied to truck operation management.

That is, as shown on the left side in FIG. 2, the track (30)
Is loaded with articles (31), but is equipped with a tag box (32) similar to that of the first embodiment, and at the time of registration, that is, when various data is written in its storage unit, the identification device for reception (3
3) and the transmission identifying device (34) are configured in the same manner as in the first embodiment, and these are combined to write necessary data into the storage section of the tag box (32) via the common antenna (35). It is like this. The operation of the truck (30) having the tag box (32) in which necessary data is written is managed according to the data, and the antenna (37) is provided in the receiving identification device (36) provided at a certain position. On the other hand, a self-identification signal is transmitted from the tag box (32), and necessary data is sent to the reception identification device (36) in addition to the self-identification signal. The receiving identification device is provided at each position according to the operation management, and necessary management is performed by transmitting necessary data at each position.

It is obvious that the same effects as those of the first embodiment can be obtained in the second embodiment.

Although the embodiments of the present invention have been described above, of course, the present invention is not limited thereto and various modifications can be made based on the technical idea of the present invention.

For example, in the first embodiment, various objects are placed on the pallet (10) at each position, but instead of this, a storage box (with a tag box) is placed on the roller conveyor for conveyance, and a predetermined amount is set. It may be applied to the production management in which the required number of various kinds of articles are input at each position.
