この発明は、光伝送路の信頼性の向上を図るようにした
車両の情報伝送装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an information transmission device for a vehicle that is designed to improve the reliability of an optical transmission line.
車両の情報伝送における光伝送路においては、その特質
上第ムーＡ図に示すように、通常ループと予備ループの
二重化ループ構成ｔとるものが多く、第１−Ｂ図のよう
に、伝送路の障害発生時ｒｃは、経ｗ！ｒ′ｔ−自動的
に切シ替え、伝送機能の喪失で最小限にするように考え
られている。Due to their characteristics, optical transmission lines used for information transmission in vehicles often have a duplex loop configuration of a normal loop and a protection loop, as shown in Figure 1-A, and as shown in Figure 1-B. When the failure occurred, the rc was in trouble! r't - automatic switching, designed to minimize loss of transmission functionality.
しかるに、従来のものは、経路のｔｒ線等の決定的な段

頼性の向上が困錐であるという入点がめった。However, since conventional devices operate only at a decisive stage such as the TR line in the path, the time required for loss of function increases. As a result, the probability of unnecessarily erroneously accepting the route t increases.In this way, it is difficult to improve reliability.
この発明は上記欠点を解消するためになされたもので、
予め伝送路の機能低下を検出し決定的な伝送経路の機能
喪失に至るまえに処置できるようにした車両の情報伝送
装置を提供するものである。This invention was made to eliminate the above drawbacks.
An object of the present invention is to provide an information transmission device for a vehicle that is capable of detecting a functional decline in a transmission path in advance and taking measures before a definitive loss of function of the transmission path occurs.

The data is transferred to No. 16, subjected to predetermined processing, converted to No. 16, and transmitted. On the other hand, the original level detection section -
The output of C and kl whose original signal level is below the level of 1 at 61 is the same as that shown in FIG. When the original signal level is smaller than the reference value t434, the lowering of the original signal level is displayed on the display t8j by the output of the original signal detection section (6), and the transmission path switching control section (1 A reheat drive command is issued.As a result, the transmission path v7 support device (10) is operated, and the transmission path is switched from the transmission path to the standby side transmission d11tta.
