Failure monitoring system for brake clamps of monorail vehicles

The utility model belongs to the electronic technical field of railways, and particularly relates to a failure monitoring system for brake clamps of monorail vehicles. The failure monitoring system comprises a monitoring control terminal and at least one set of pressure detecting units, wherein each pressure detecting unit comprises an electronic brake control unit (EBCU) and a detection terminal. The failure monitoring system is characterized in that the independent pressure detection units are respectively arranged on the compartments; each detection terminal comprises a pressure switch mounted at an exhaust hole of a bracket brake oil-cylinder to be used for detecting the pressure at a brake clamp, and the pressure switch is connected with the corresponding electronic brake control unit (EBCU) so as to form a detection circuit with 110 V; the electronic brake control unit (EBCU) of each pressure detecting unit is connected to the monitoring control terminal arranged in a driver control chamber, and the alarm pressure value of each pressure switch can be set through the monitoring control terminal. When no brake command is applied, the pressure value at the pressure switch of one brake detection unit is larger than the alarm pressure, the detection circuit with 110 V is shut down, and the brake failure is confirmed.
