【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。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an individual identification method in which an individual is identified by a master station reading the contents of a slave station memory attached to each individual without contact.
か＼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、このため場合によっては
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 individual identification systems, the individual units to which the slave stations are attached often move, and as a result, the slave stations may be exposed to extremely harsh environments, causing data in the slave stations to be destroyed. There is a risk that this may occur.
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 there is any abnormality in the data from the slave stations.
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 approach not only increases the burden on the master station, but also causes problems in that the processing takes time. Furthermore, even if data abnormalities can be detected, the system does not have a function to repair them, so there is also the problem that data abnormalities can make the system unusable.
したがって、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, it is an object of the present invention to reduce the burden on the master station and improve reliability by allowing the slave station to detect abnormalities in data and repair them.
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 is equipped with a means for detecting data abnormalities and a means for restoring the data when an abnormality is detected, and the data abnormality is detected every time the slave station communicates with the master station before transmitting the data. Data restoration 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って、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。To prevent data of a slave station from becoming unusable due to inability to determine data by restoring data when an abnormality is detected. In addition, data restoration requires processing time such as memory transfer time, but since data restoration processing is performed after data transmission is completed, data restoration is possible without affecting the communication timing between the master station and slave station. .
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者と異なっている
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 methods for detecting and repairing data abnormalities, but here we will use three copies of the same data in the slave station memory (
Data anomaly is detected by majority decision, and if only one item is different from the other two, it is determined that that memory has been destroyed, and other matching items are stored in that memory area. An example will be described in which data is transferred and restored from one memory area of the two.

が子局２のデータを読み出して移動体の識別を行う。Figure 1 shows an example of an individual identification system. Data such as an identification code is written into the slave station 2 attached to the mobile body 3 by the master station 1 at point PL. Mobile object 3
When the mobile unit moves and reaches the P2 point, one master station reads the data of the slave station 2 and identifies the mobile unit.

（１２Ｂ）。Figure 2 shows the configuration inside the slave station. The slave station is contactless communication device 1
0 receives a command from the master station, and according to the command, the CPU II reads or writes data from the memory, and the read data is transmitted to the master station via the contactless communication device 10tl-. Ru. For majority decision, the memories are memory 1 (12A) and memory 2.

る。The individual identification operation will be explained. First, data is written by the master station 1 to the slave station 2 at the position of point lP1 in FIG.
carried out by The slave station 2 receives all data to be written from the master station 1. CPOII in FIG. 2 is written in triplicate if there is no communication error in these data. As a result, the same data is stored in memories 1, 2, and 3.

手順全第３図に示す。子局は親局からの送信コマンドを

有無をチエツクする。When the moving body 3 moves to the position P2 in FIG. 1, one master station reads data from the slave station 2. The entire procedure is shown in Figure 3. When the slave station receives a transmission command from the master station, it checks the logic of the command and the presence or absence of communication errors during reception processing.

A majority decision is made. At this threshold, the slave station transmits a leading signal. This is to ensure stable communication between the slave station and the master station, and to keep the receiving device of the contactless communication device of the master station in a marked state.

ない。As a result of the majority judgment of memories 1, 2, and 3, if all 3 @ match, the data is considered normal, one of the three is sent in the data transmission process, and the master station indicates that it is normal in the abnormality flag transmission process. will be notified, and data recovery processing will not be performed. As a result of majority decision, if two parties agree and one does not,
The one that does not match is regarded as data destruction, and in the data transmission process, one of the two that matches is sent,
In the abnormality flag transmission process, the master station is notified that the data is normal, and in the data restoration process, the data is restored by transferring the memory contents of one of the two matched areas to the different memory area. If the result of the majority decision is that all three are completely different, it is determined that the data is abnormal, one of the three is transmitted as a dummy in the data transmission process, and the master station is notified of the abnormality in the abnormality flag transmission process. No data recovery processing is performed.
この時、子局のデータは使用不能となる。At this time, the data of the slave station becomes unusable.

きる。[Effects of the Invention] According to the present invention, the memory of the slave station is checked every time there is communication and is repaired as much as possible, thus actively preventing data becoming unusable and reducing the probability of its occurrence. be able to. In addition, since the data restoration process is performed after the data transmission is completed, the restoration processing time does not affect the communication timing between the master station and the slave station. You can improve your performance.
