Abstract
An optical communication equipment performs optical communication between a first apparatus and a second apparatus. The optical communication equipment includes a monitoring section configured to monitor a light amount during optical communication, and a control device configured to output predetermined information when the light amount is less than a first threshold value and shut off communication between the first and second apparatuses when the light amount is less than a second threshold value lower than the first threshold value.
Claims6
An optical communication equipment for performing optical communication between a first apparatus and a second apparatus, comprising:
- a monitoring section configured to monitor a light amount during the optical communication;
- and
- a control device configured to
- output predetermined information when the light amount is less than a first threshold value and shut off communication between the first and second apparatuses when the light amount is less than a second threshold value lower than the first threshold value, and
- perform communication between the first and second apparatuses in a limited manner which includes checking whether there is an abnormality in at least one of the first apparatus or the second apparatus, when the light amount is less than a third threshold value lower than the first threshold value and higher than the second threshold value.
A component mounting machine for mounting a component, comprising:
- a mounting machine body;
- a mounting head that moves with respect to the mounting machine body to mount a component;
- and
- an optical communication equipment for performing optical communication between the mounting machine and the mounting head, including:
- a monitoring section configured to monitor a light amount during the optical communication, and
- a control device configured to output predetermined information when the light amount is less than a first threshold value and shut off communication between the mounting machine and the mounting head when the light amount is less than a second threshold value lower than the first threshold value, wherein
- the mounting head includes a motor and an encoder configured to detect displacement of the motor, and
- the mounting machine body includes a motor control section configured to drive and control the motor by receiving an encoder signal output from the encoder via the optical communication equipment and transmitting a control signal to the motor via the optical communication equipment.
