WIPO Patent Application WO/2019/029655
Kind Code:
A1
Abstract:
Provided are a method and device for monitoring a filament state of a signal lamp device, and an interlocking system. The method comprises: determining, during a current operating cycle of an interlocking system, occupancy states of respective sections in which respective signal lamp devices are located, lengths of the respective sections being greater than a critical distance within which the naked eye can determine whether the signal lamp device is on; determining a currently unoccupied section as a target lighting section; driving a target signal lamp device in the target lighting section to turn on; and determining, according to a lighting state of the target signal lamp device, a filament state of the target signal lamp device.
