通信を行なうことができる。(Effects of the Invention) The communication device according to the present invention has a distinguishable first state and a second state.
a transmitting device capable of transmitting the state, a receiving device capable of receiving the two states sent by the transmitting device, and a transmitting device that sequentially converts a series of information into the two states; After transmitting one state, if the state is the first state, the second state is sent,
If it is the second state, a first conversion device transmits the first state of AfJ, and temporarily stores the state received by the receiving device, and the state received thereafter is the temporarily stored state. If they do not match, the temporarily stored state is taken in to form reception information, and if they match, it is assumed that there was an abnormality in transmission and reception, and measures such as aborting reception are taken to detect communication abnormalities at an early stage. Since the configuration includes a second conversion device that performs the conversion, if the state transmitted from the transmitting device is not correctly received by the receiving device, the abnormality can be detected early, and highly reliable communication can be achieved. can be done.
