Abstract: The gap detection system detects whether there are obstacles between the platform doors and the train doors, achieving the gap safety protection function through coordination with the signaling system. Generally, there are two ways for the signaling systems of fully automatic driverless lines to obtain the gap detection information. One is to directly interface with the gap detection system, and the other is to interface with the platform door system, which is provided with the information from the gap detection system. Starting by examining the two different interface modes, this paper introduces the differences between these modes according to their working time sequences, compares and analyzes these modes from the aspects of interface quantities and information, interface data flows, bypass modes and detection timing, and puts forward optimization suggestions based on the characteristics of actual applications in specific projects. The two interface modes both have advantages and disadvantages. For different projects, one of these modes can be selected according to the differences between the platform door systems and the gap detection systems from various manufacturers in the detailed design stage, along with the proposed optimization suggestions.
