Title:
NURSE CALL SYSTEM AND CONTROL MACHINE
Document Type and Number:
Japanese Patent JP2018067823
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent the function of nurse call from being stopped even upon occurrence of a failure or during maintenance, without duplicating the facility such as a control machine, or modifying an existing facility other than the control machine.SOLUTION: A control machine 2 includes a main control circuit 21 controlling the communication for transmitting the call from a nurse call slave unit 5 to a nurse call master unit 1, a sub-control circuit 22 controlling the communication for transmitting the call from the nurse call slave unit 5 to a corridor lamp 3, and a changeover control section 23 for operating while changing over from the main control circuit 21 to the sub-control circuit 22, when the fact that the main control circuit 21 is in the inoperative state was detected. The function of nurse call is prevented from being stopped even upon occurrence of a failure or during maintenance, without changing the existing configuration itself of the nurse call system itself, by making the internal circuit of the control machine 2 redundant by the main control circuit 21 and sub-control circuit 22.SELECTED DRAWING: Figure 2
