RAILWAY VEHICLE DRIVER'S BRAKE VALVE CONTROLLER Russian patent published in 2004 - IPC

FIELD: railway transport. SUBSTANCE: controller is designed for remote control of brake valve by delivering electric control signals to electropneumatic control members of brake valve. Each electric control signal transmission member has magnetically controlled microcircuit, electric control signal propagation time delay element, RS type criss-cross flip-flop, diode and resistor. Output of microcircuit is connected with input R and input S through flip-flop diode. Inputs S of flip-flops of all members are interconnected. Device for switching on electric control signal transmission members from supply source to control electropneumatic member of brake valve is made in form of shape magnetic circuit. Magnetizing coils are mounted on outer fixed cores. Central core is made in form of magnetic concentrator. Housing serves as base of magnetic circuit. Magnetic concentrator is coupled with handle and it moves over electric control signal transmission members and base of magnetic circuit. Clearance between magnetic concentrator and geometric centers of magnetically-controlled microcircuits is less than clearance between concentrator and base of magnetic circuit. Coils are connected to supply source is series with voltage-stabilizing diode. Preliminary setting member of RS type flip-flops is connected in parallel with said type RS flip-flops and is provided with voltage-stabilizing diode and resistor, series-connected logic NOT gates being connected to their common point. Output of logic NOT gate is connected with inputs S of all type RS flip-flops through diode 37. Stabilized voltage is applied to terminals. Output Q of each type RS flip-flop is connected, respectively, with electric circuit. Said circuits are coupled with control electropneumatic members of brake valve. Invention prevents violation of process of transmission of electric control signal to control electropneumatic member of brake valve in each brake position and provides transmission of electric control signal to corresponding control electropneumatic member of brake valve in each preceding brake position till moment of beginning of delivery of control electric signal in following brake position. EFFECT: improved reliability in operation. 3 cl, 2 dwg
