AERIAL LADDER BOOM AUTOMATIC CONTROL SYSTEM OF FIRE TRUCK WITH AERIAL LADDER

摘要

The present invention provides a ladder boom automatic control system of the ladder fire truck. The control system of the present invention is a ladder fire truck including a multi-stage ladder boom which is erectably installed around a pivot center on a vehicle body, a boom cylinder for standing the ladder boom upward, and a cable type driving device for deploying the ladder boom. A horizontal distance measuring means for measuring a horizontal distance between a pivot center of the ladder boom and a fire point; Vertical angle measuring means for measuring a vertical angle of a fire point with respect to the pivot center of the ladder boom; Electronic control that outputs a signal by processing the horizontal distance measured by the horizontal distance measurer and the vertical angle measured by the vertical angle measurer to calculate the standing angle of the ladder boom at the fire point and the deployment length of the ladder boom at the fire point, respectively. A unit; According to the ladder boom standing angle control signal and ladder boom unfolding length control signal of the electronic control unit, it is equipped with a hydraulic device to control the boom cylinder and the cable type driving device to stand the ladder boom to the fire point and to deploy it to the fire point.
