This application can get specific information faster and improve the efficiency of the maintenance engineer’s definition of fault information when a fault occurs. The chatbot uses LINE’s Message API to provide services, and obtains information and status of the front-end system over EPICS protocol, responding to users’ needs, like a virtual assistant. At present, the application can obtain the front-end system information already in operation of Taiwan Photon Source, including x-ray beam position monitor, safety interlock system, front-end valve status, vacuum status…etc. However, in addition to the passive provision of information, this program has a fault warning function, and will actively transmit fault information to relevant personnel when a problem occurs in the safety interlock system.
