Title: Interphone system
Inventor: YAMAGISHI TAKATOSHI
IPC: H04N7/18
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To limit the supply of power for protecting a system when shorting occurs in the system without using the parts of a large loss tolerance and to automatically restore power after shorting is removed by providing a means for supplying power into the system at a prescribed interval and repetitively detecting shorting. SOLUTION: A video controller 11 supplies power to a camera 10 and a monitor 15. When shorting occurs in any part, large current flows in it and therefore it is necessary to prevent the occurrence of a fault in a system. Thus, a shorting detection circuit 18 does not use the transistor of a large loss tolerance and a regular current limit circuit limits that the current of more than prescribed quantity does not flow. A current detector detects current and the supply of power is interrupted after a prescribed time when shorting is detected based on the current value. Current is once made to flow after a prescribed time and an operation for detecting the current is repeated and shorting is detected.
