Switch state detecting system based on switch blade displacement

The utility model discloses a switch state detecting system based on switch blade displacement comprises on -the -spot industrial computer and switch state detection device, switch state detection device is equipped with the displacement sensing module, the displacement sensing module includes left side and right side laser displacement sensor, left side and right side laser displacement sensor fix on track bed and follow the axis symmetric distribution of left side stock rail and right side stock rail through the installation base respectively, they all are located between left side switch blade and the right side switch blade, the inboard vertical terminal surface of left side laser displacement sensor's the perpendicular directional left side switch blade of laser export, the inboard vertical terminal surface of right side laser displacement sensor's the perpendicular directional right side of laser export switch blade, output was for data collection card after the leading data processing circuit of on -the -spot industrial computer received each left side laser displacement sensor and right side laser displacement sensor's output signal and converts it to data signal. The utility model discloses can realize the non -contacting pickup to switch blade overall process motion state.
