Problems solved by technology
With the increase of on-board instruments and equipment in emergency command vehicles, the power supply input, power supply mode and power supply sequence of the entire on-board power supply and distribution system become more and more complicated
In order to meet the power supply and distribution of various vehicle-mounted instruments and equipment, the vehicle-mounted power supply and distribution system is equipped with a vehicle-mounted distributor. Monitoring cannot meet the timing requirements of instruments and equipment for various working conditions, which reduces the intelligence and informatization of on-board power distribution
