Obstacle avoidance protection:When an obstacle is detected in front of the vehicle during operation,maintain a follow-up distance or brake.
  Cabin interlock protection:When one of the front and rear cabins is started,the other cannot be started.
  Emergency braking protection:The cab is equipped with traction and master stop buttons,which can be directly pressed to control the locomotive to stop in case of emergency;Equipped with a manual unloading valve,in case of emergency,the locomotive can be manually operated to stop.
  Overspeed protection:When the running speed of the locomotive exceeds 15%of the designed maximum running speed,the locomotive will sound an alarm and emergency stop.
  Anti slip protection:When climbing hills,diesel cars are started by holding pressure to prevent the vehicle from slipping;Trams increase the frequency of the motor and delay starting to prevent the vehicle from slipping.
  Interlocking protection for crane lifting:During vehicle operation,the lifting beam cannot be lifted.
  Fire protection:Equipped with fire extinguishers,it can achieve manual or automatic triggering of fire extinguishing.
  Oil change reminder:According to the oil change requirements of the hydraulic system,the system sets the oil change time and automatically alarms when the oil change time is reached.
  Over temperature protection:When the hydraulic system oil temperature exceeds 75°C,the locomotive will sound an alarm and stop.
  Overload protection:When the weight of goods transported by the locomotive exceeds the designed maximum weight,the locomotive will sound an alarm and stop.
  Low battery/oil level protection:When the battery level is too low,an alarm will be triggered;When the diesel oil level is too low,an alarm will sound.
  Leakage protection(tram):Install DC insulation protection device to detect whether the monorail crane is leaking electricity.
  CO over limit protection:The carbon monoxide sensor will sound an alarm and stop when the CO concentration reaches 0.0024%.
  Switch abnormal protection:When the vehicle is 50 meters away from the switch,check whether the switch is in place.If it is not in place,control the locomotive to stop.
  Gas concentration exceeding limit shutdown protection:The gas sensor will alarm when the gas concentration reaches 0.8%,and emergency power will be cut off and stopped when the gas concentration reaches 1%.
