Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、個体別に取り付けられた子局メモリの内容
を親局が非接触で読み出すことにより、個体の識別を行
なう個体識別方法に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an individual identification method for identifying an individual by allowing a parent station to read the contents of a child station memory attached to each individual in a non-contact manner.
かゝる個体識別システムでは、子局が取り付けられてい
る個体は移動することが多く、このため場合によつては
子局が極めて過酷な環境下におかれることがあり、子局
内のデータが破壊されてしまうおそれがある。In such an individual identification system, the individual to which the slave station is attached often moves, which may cause the slave station to be placed in an extremely harsh environment, and the data in the slave station may be lost. It may be destroyed.
そこで、従来は専ら親局で子局からのデータに異常がな
いか否かの検出を行うようにしている。Therefore, conventionally, the master station exclusively detects whether or not the data from the slave station is abnormal.
しかしながら、このようにすると親局の負担が増大する
だけでなく、処理に時間が掛かると云う問題がある。ま
た、データの異常は検出できてもそれを修復する機能迄
は有していないため、データ異常で使用不能になると云
う問題もある。However, this not only increases the load on the master station, but also causes a problem that the processing takes time. Further, even if an abnormality of data can be detected, it does not have a function of repairing it, so that there is a problem that it becomes unusable due to the abnormality of data.
したがつて、この発明は子局側でデータの異常検出とそ
の修復ができるようにして親局側の負担を軽減し、信頼
性の向上を図ることを目的とする。Therefore, an object of the present invention is to reduce the load on the master station side and improve the reliability by allowing the slave station side to detect the abnormality of the data and repair it.
子局にデータの異常を検出する手段と、異常検出時にデ
ータの修復を行う手段とを持たせ、親局との交信のたび
にデータの異常検出を子局のデータの送信前に行い、異
常検出時のデータ修復を子局のデータ送信後に行う。The slave station should be provided with a means to detect data anomalies and a means to restore the data when an anomaly is detected. Data recovery at the time of detection is performed after data transmission from the slave station.
異常検出時にデータの修復を行うことによつて、データ
確定不能のために子局のデータが使用不能となることを
防止できるようにする。また、データ修復にはメモリ転
送時間等の処理時間を要するが、データ修復処理をデー
タ送信終了後に行うようにしたため、親局と子局の交信
タイミングに影響を与えずにデータ修復が可能となる。By repairing the data when an abnormality is detected, it is possible to prevent the data of the slave station from becoming unusable due to the indeterminability of the data. Also, although data restoration requires processing time such as memory transfer time, since data restoration processing is performed after data transmission is completed, data restoration can be performed without affecting the communication timing between the master station and slave stations. .
データの異常検出及び修復方法には色々なやり方が考え
られるが、ここでは子局メモリ内に同一データを３重
（多重）にメモリしておき、多数決判定によりデータ異
常検出を行い、もしも１者だけが他の２者と異なつてい
るときはそのメモリが破壊されたと判断して、そのメモ
リ領域へ他の一致した２者のうちの１つのメモリ領域か
らデータを転送して修復する例について述べる。There are various possible methods for detecting and repairing data anomalies. Here, the same data is stored in triple (multiple) memory in the slave station memory, and the data anomaly is detected by the majority decision. Only when it is different from the other two, it is judged that the memory has been destroyed, and an example in which data is transferred from one of the other two matched memory areas to the memory area and repaired is described. .
第１図に個体識別システム例を示す。移動体３にとり付
けられた子局２に対し、ポイントP1にて親局１により例
えば識別コード等のデータが書き込まれる。移動体３が
移動してP2ポイントのところまで行くと、親局1Aが子局
２のデータを読み出して移動体の識別を行う。FIG. 1 shows an example of an individual identification system. At the point P 1, the master station 1 writes data such as an identification code to the slave station 2 attached to the mobile unit 3. When movable body 3 moves go far P 2 point, and identifies the mobile reads the data of the master station 1A child station 2.
第２図に子局内の構成を示す。子局は非接触交信装置10

にメモリはメモリ１（12A），メモリ２（12B），メモリ
３（12C）に３重化されている。メモリ1,2,3には基本的
にエラーがなければ同一のデータが書かれている。FIG. 2 shows the internal structure of the slave station. Slave station is a contactless communication device 10
Receives a command from the master station, the CPU 11 reads data from the memory or writes data according to the command, and the read data is transmitted to the master station via the non-contact communication device 10. . The memory is tripled into a memory 1 (12A), a memory 2 (12B), and a memory 3 (12C) for the majority decision. Basically, the same data is written in memories 1, 2, and 3 if there is no error.
個体識別動作について説明する。まずデータ書き込み

データをメモリ１（12A），メモリ２（12B），メモリ３
（12C）に３重に書く。このことにより、メモリ1,2,3に
は同一のデータがメモリされる。The individual identification operation will be described. First, for data writing, the master station 1 with respect to the slave station 2 at the position of point P 1 in FIG.
It is carried out by. The slave station 2 receives the data to be written from the master station 1. The CPU 11 in FIG. 2 checks whether or not there is a communication error in these data. If they are normal, the data is stored in memory 1 (12A), memory 2 (12B), memory 3
Write in triple (12C). As a result, the same data is stored in the memories 1, 2, and 3.
第１図において移動体３がポイントP2の位置へ移動した
とき、親局1Aは子局２からデータを読み出す。その手順
を第３図に示す。子局は親局からの送信コマンドを受信
すると、受信処理でコマンドの論理や交信エラーの有無

の多数決判定を行う。この間、子局はリーデイング信号
を送信する。これは子局→親局の交信を安定に行うため
のもので、親局の非接触交信装置の受信装置をマーク状
態に保つものである。In FIG. 1, when the mobile unit 3 moves to the position of point P 2 , the master station 1A reads data from the slave station 2. The procedure is shown in FIG. Upon receiving the transmission command from the master station, the slave station checks the logic of the command and the presence or absence of a communication error in the reception process. If this is correct, the CPU will then go to memory 1,2,3
Make a majority decision. During this time, the slave station transmits a reading signal. This is for stable communication from the slave station to the master station, and keeps the receiving device of the non-contact communication device of the master station in the mark state.

であることを親局に通知し、データ修復処理は行わな
い。この時、子局のデータは使用不能となる。As a result of the majority decision of the memories 1, 2, and 3, if all three match, the data is normal, one of the three is transmitted in the data transmission process, and normal in the abnormality flag transmission process. And the data restoration process is not performed. As a result of the majority decision, when two parties match and one does not match, the one that does not match is considered to have destroyed data, and one of the two parties that match is transmitted in the data transmission process, and an abnormal flag is transmitted. In the process, the master station is notified that the process is normal, and in the data restoration process, the memory contents of one of the two matched data are transferred to the wrong memory area to restore the data. As a result of the majority decision, if all three are different, it is judged as a data error, and in the data transmission process it is judged as a dummy
One of them is transmitted, the abnormality flag transmission processing is notified to the master station that there is an abnormality, and the data restoration processing is not performed. At this time, the data of the slave station cannot be used.

きる。According to the present invention, the memory of the slave station is checked every communication and is repaired as much as possible. Therefore, it is possible to positively prevent the data from becoming unusable and reduce the occurrence probability. Also, since the data restoration process is done after the data transmission is completed, the restoration process time does not affect the communication timing between the master station and the slave station, and therefore the control of the master station side is not changed at all, and the restoration of the It is possible to improve the property.
