Abstract
To detect an error in pulse width in a communication scheme that identifies a start position of a message or expresses a data value using a pulse width of a pulse included in the message, provided is a receiving apparatus including a receiving section that receives a message including a synchronization pulse having a predetermined pulse width and a first data pulse having a pulse width corresponding to a value of first data; and an error detecting section that detects an error in response to the number of non-synchronization pulses that are consecutive after the synchronization pulse being outside a predetermined number range.
Claims10
A receiving apparatus comprising:
- a receiving section that receives a message including a synchronization pulse having a predetermined pulse width and a first data pulse having a pulse width corresponding to a value of first data;
- an error detecting section that detects an error in response to a number of non-synchronization pulses that are consecutive after the synchronization pulse being outside a predetermined number range;
- a synchronization pulse detecting section that detects, as the synchronization pulse, a pulse having a pulse width that is within a predetermined synchronization pulse allowable width range including the predetermined pulse width;
- and
- a data pulse detecting section that detects, as the first data pulse, a pulse at a predetermined pulse position using the synchronization pulse as a reference.
A receiving apparatus comprising:
- a receiving section that receives a message including a synchronization pulse having a predetermined pulse width and a first data pulse having a pulse width corresponding to a value of first data;
- an error detecting section that detects an error in response to the pulse width of the first data pulse being outside a predetermined data pulse allowable width range;
- a synchronization pulse detecting section that detects, as the synchronization pulse, a pulse having a pulse width that is within a predetermined synchronization pulse allowable width range including the predetermined pulse width;
- and
- a data pulse detecting section that detects, as the first data pulse, a pulse at a predetermined pulse position using the synchronization pulse as a reference.
A transmission apparatus comprising:
- a transmission data acquiring section that acquires a plurality of sets of first data and second data to be transmitted;
- a message generating section that generates a plurality of messages in a message group, each one message of the plurality of messages including a synchronization pulse having a predetermined pulse width, a first data pulse having a pulse width corresponding to a value of the first data that corresponds to the one message, among the plurality of sets of the first data, and a second data pulse having a pulse width corresponding to a value of partial data that is of the second data and to be encoded in the one message;
- and
- a transmitting section that transmits each one message of the plurality of messages in the message group, wherein
- the message generating section encodes additional information in a reserved field of the partial data expressed by the second data pulse.
