The output unit includes a readback circuit that detects whether or not the signal is outputted from the output unit. The controller makes a signal stop request and a signal output request to the output unit before operation of the train starts, acquires a detection result of the readback circuit while each of the signal stop request and the signal output request is performed, and detects abnormality of the output unit using the detection result."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal control device and abnormality detection method","description":"A RIO device mounted to a train includes an output unit that outputs a signal to a relay mounted to the train, and a controller that controls whether or not to cause the output unit to output the sign","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11938980","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
