Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Such as Figures 1 to 3 As shown, the turnout control module can control the three-phase four-wire system 380VAC drive turnout, and can accurately determine the position of the turnout. Take the Siemens switch machine S700K as an example for the turnout.

[0017] The invention provides a turnout control module, which includes an FPGA, a turnout drive circuit and a display circuit.

[0018] The FPGA includes FPGA1 and PGA2.

[0019] The switch driving circuit includes a fuse, an isolation circuit, a current detection circuit, a power switch circuit and a logic commutation switch circuit. The isolation circuit uses an electronic load relay to realize the isolation of DC and AC. The current detection circuit includes a current transformer and an operational amplifier circuit for real-time monitoring of the current information of the switch machine act...

Abstract

The invention discloses a turnout control module and a full-electronic implementing method thereof. A turnout driving circuit of the turnout control module sends turnout driving control commands to two FPGAs respectively, three-phase alternating currents pass through a driving circuit and a cable to form a circuit together with a turnout motor coil, and a motor is powered on and starts to rotate;after a turnout rotates to the bottom, a three-phase power supply is removed, and the rotating movements of the turnout are completed. At the moment, the cable connected with an automatic shutter of the turnout converts expression voltages into level signals through a detecting circuit to be output to the two FPGAs, and the position of the turnout is judged. The turnout control module as an interface module of the outdoor device turnout receives a linked host driving command through an inner bus to rotate the external turnout, and after the turnout rotates to the position, the position information representing the circuit collecting turnout is sent to a linked host through the inner bus.

Description

technical field [0001] The invention relates to a realization method suitable for all-electronic computer interlocking and full-electronicization of a turnout control module, in particular to a realization method of a full-electronicity of a turnout drive circuit and a display circuit. Background technique [0002] The switch control circuit realized by the traditional 6502 electrical centralized execution group relay uses a single-action switch combination, a resistance-capacitance plug-in, and a diode. Among them, the single-action turnout combination includes a display transformer, a turnout start relay, a locking relay, a second turnout start relay, a turnout button relay, a fixed operation relay, a reverse operation relay, a positioning display relay, a reverse position display relay, and a 0.5A fuse device, two 3A fuses and one 5A fuse. The relays in the circuit are all safety relays, which are large in size and need to be installed in the relay combination cabinet, a...
