Abstract
【解決手段】連動論理分3から送られる正論理信号と負論理信号が伝送周期毎に反転する制御情報を、1系の端末装置4と2系の端末装置5で入力して、1系の端末装置4と2系の端末装置5でLED信号機のLED2を同時に制御する。1系の端末装置4と2系の端末装置5でLED2を点灯制御しているとき、1系の端末装置4と2系の端末装置5のFSCPU6は、連動論理部3から送られる正論理信号と負論理信号により交互に故障診断を行い、1系の端末装置4と2系の端末装置5のいずれか一方に故障が生じた場合は、故障した端末装置をLED2から迅速に切り離し、その旨を連動論理部3に知らせるとともに故障していない端末装置でLED2を点灯させて安全を確保する。

Claims (2)
- 主装置及び1系と2系の端末装置を有し、LED信号機のLEDを制御するLED信号機制御装置において、
前記主装置は、正論理信号と負論理信号が伝送周期毎に反転する制御情報を、前記1系の端末装置と2系の端末装置に送信し、
前記1系の端末装置と2系の端末装置は、中央処理部と、直列に接続され、前記LEDに供給する電流を制御する2組の制御素子と、LEDに供給する電流を検出する電流センサを有し、
前記1系と2系の中央処理部は、前記主装置から送られる制御情報を入力して、前記直列に接続された2組の制御素子の動作を制御して前記LEDを並列制御し、前記1系の端末装置の中央処理部は、前記主装置から正論理信号が入力したとき、前記2組の制御素子を別個にオフにして、前記電流センサで検出した電流値により、前記各制御素子の故障を診断し、前記2系の端末装置の中央処理部は、前記主装置から負論理信号が入力したとき、前記2組の制御素子を別個にオフにして各制御素子の故障を診断することを特徴とするLED信号制御装置。 - 前記1系の端末装置と2系の端末装置の中央処理部は、故障診断を行うときに他系の端末装置に対して故障診断を行うことを通知し、故障診断を交互に切り換える請求項1記載のLED信号制御装置。
