摘要: Biological signals detected by biological signal detecting units put on a plurality of persons to be monitored are transmitted wristwatches. The and ID code data corresponding the in form radio signals. A receiver unit receives from wristwatches sends them monitor unit. displays one-to-one correspondence with data, Upon an abnormality given signal, generates alarm sound.
