At present, the appliance of mine aerial cable locomotive is clear at large in the assistant transport of mine, the safety moving relates the safety production, and the brake system that can intellectually identify the red and green light signal is the guarantee of the safety moving. This paper introduces the principle of intellectually pneumatic brake system and finite element analyzes the mostly component. It provides theory and practice basic for framework design and the choice of pneumatic components; the intellectual brake system design of the mine aerial cable locomotive uses a 8031 single chip microprocessor as CPU, using infrared ray remote controlled emit and receive system as the measuring component to measure whether the mine locomotive comes near the curve or branch. When system receives the infrared signal with different position coding, it can broadcast correspond sound information ,and decelerate. When mine aerial cable locomotive runs forty distance or subter-forty distance from the position that the red light is placed, it brakes when the red light is lighted or runs continually. Moreover, the paper introduces the problem that mine aerial cable locomotive avoids fire in startup, brings forward a circuit design scheme, which can automatic draught the bow and break electricity when the mine aerial cable locomotive's temperature is up to the finite number.
