The invention discloses a subway
train distance detection system. The
system comprises a controller arranged on a subway
train, a
radar detection
system, a driving state system, a displayer, an alarm system, a power supply system and a
signal transceiving device, wherein the
radar detection system, the driving state system, the displayer, the alarm system, the power supply system and the
signal transceiving device are connected with the controller; the
signal transceiving device is connected with the controller and used for carrying out
information transmission with a signal transceiving device on an adjacent subway
train; the
radar detection system comprises a radar
detector; the driving state system comprises one or more train speed sensors; the displayer is a touch display screen; the alarm system comprises two voice alarms, two buzzers and a subway train outline marker lamp; the power supply system comprises a
control switch connected with the controller, and a subway train vehicle-mounted power supply connected with the
control switch; the controller is further connected with a speed reducing system of the subway train and a
brake system. According to the subway train
distance detection system, the problem that the subway train distance cannot be effectively detected in the prior art is solved, so that the situation of traffic accidents such as rear-end collision occur is avoided.
