Abstract:
1. A display information collecting device that is connected to a control device and collects internal information in the control device for display, the device comprising: a motion sensor that detects a location of an operator who is located within a first range in a vicinity of the display information collecting device; a wireless communication interface that is a wireless communication interface for performing wireless communication with a personal digital assistant that includes a display and stores unique information and whose communicable radio coverage area is a second range that is larger than the first range in a vicinity of the display information collecting device; and a control unit that transmits, to the personal digital assistant via the wireless communication interface, the collected internal information and screen data that shapes the collected internal information for display, in order to cause the display of the personal digital assistant to display the collected internal information, wherein the control unit, when the motion sensor detects a location of an operator, acquires unique information from all personal digital assistants within the second range including a personal digital assistant owned by the operator via the wireless communication interface and authenticates each of the personal digital assistants on a basis of the acquired unique information; when authentication is successful, transmits the screen data and the collected internal information to a first personal digital assistant for which the authentication is successful; and, when authentication fails, disconnects communication with a personal digital assistant for which the authentication fails without transmitting the screen data and the collected internal information to the personal digital assistant for which the authentication fails, and after the control unit starts to transmit the collected internal information to the first personal digital assistant, the control unit repeatedly performs detection of an operator within the first range and, when an operator is detected within the first range, acquisition of unique information from all personal digital assistants within the second range and authentication based on the acquired unique information; when the motion sensor does not detect a location of an operator, disconnects communication with all personal digital assistants within the second range including the first personal digital assistant; when authentication of the first personal digital assistant is successful, continues to transmit the collected internal information to the first personal digital assistant; when authentication of a second personal digital assistant, which is different from the first personal digital assistant, is newly successful, transmits the screen data and the collected internal information to the second personal digital assistant; and, when authentication fails, disconnects communication with a personal digital assistant for which the authentication fails.
