Production line monitoring system

A production line monitoring system for monitoring a production line including a plurality of production devices, the production line monitoring system comprising:

• a plurality of terminals attached to a plurality of workers;
• and
• a server configured to communicate with the plurality of terminals via a wireless network,
• wherein the server performs:
• processing of receiving operation information about a production device of the plurality of production devices and generating event information based on the operation information,
• processing of transmitting the event information to a first terminal of the plurality of terminals and a second terminal of the plurality of terminals,
• processing of receiving response information from the first terminal based on the transmission of the event information to the first terminal and the second terminal, and
• processing of transmitting event stop information to the second terminal based on the reception of the response information;
• and
• a memory configured to store a table where whether or not to transmit the event information to each of the plurality of terminals is defined, wherein
• the table includes an identification (ID) of each of the plurality of production devices, an ID of each of the plurality of terminals, and an operation type corresponding to the event information, and
• the server further performs, based on the table, processing of determining at least one terminal of the plurality of terminals to which the event information is transmitted.
