To provide a signal reading system that generates a code identification signal capable of identifying a code indicated by a logic signal of a communication path to output it to an analysis device, and that gives notice when a signal collision with the analysis device occurs.SOLUTION: A signal reading system includes: a CAN driver 3 that converts a code identification signal Sf indicating a logic signal Sa into a transmission signal STX and outputs it from a pair of output terminals to an analysis device; a CAN receiver 5 that receives the signal generated between the pair of output terminals and outputs it as a reception signal SRX; a comparison unit 7 that compares logics of the code identification signal Sf and the reception signal SRX and outputs an output signal So indicating match/mismatch between the logics; and a processing unit 9 that performs notification operation when the output signal So (So1) indicating mismatch is input.SELECTED DRAWING: Figure 1
【課題】通信路のロジック信号で示される符号を特定可能な符号特定用信号を生成して解析装置に出力し、かつ解析装置との間に信号の衝突が発生したときにはそれを報知する。【解決手段】ロジック信号Saを示す符号特定用信号Sfを送信信号STXに変換して一対の出力端子から解析装置に出力するCANドライバ3と、この一対の出力端子間に生じている信号を受信して受信信号SRXとして出力するCANレシーバ5と、符号特定用信号Sfおよび受信信号SRXの論理同士を比較して、この論理同士の一致・不一致を示す出力信号Soを出力する比較部7と、不一致を示す出力信号So(So1)を入力したときに、報知動作を実行する処理部9とを備えている。【選択図】図1
