The present invention relates to a voltage signal processing unit (120, 220), a landing door fault location system (100, 200) and method, and an elevator system. The landing door fault location system (100, 200) and method and the elevator system comprise or use the voltage signal processing unit (120, 220). The voltage signal processing unit (120, 220) comprises: a first voltage signal input port (121, 221); a second voltage signal input port (122, 222); a first electrical level signal output port (123, 2231); a first voltage signal collection circuit, the first voltage signal collection circuit terminates with the first voltage signal input port (121, 221) and the first electrical level signal output port (123, 2231), the first voltage signal collection circuit is adapted to collect a first voltage signal received from the first voltage signal input port (121, 221) as a first electrical level signal output from the first electrical level signal output port (123, 2231); and a voltage signal bridge circuit, the voltage signal bridge circuit terminates with the first voltage signal input port (121, 221) and the second voltage signal input port (122, 222), a normally open relay switch (124, 224) is provided between the first voltage signal input port (121, 221) and the second voltage signal input port (122, 222).
