Abstract
A control system for a surveillance vehicle (V) is disclosed. The vehicle includes a rapid deployment and retraction mechanism (A') and a jack system (B') for continuously maintaining a detection device (28) a top a mast (12) within a prescribed vertical condition when extended. The control system includes a jack leveling logic circuit (C), a jack pressure control circuit (D), a ram control circuit (E), and a mast control circuit (F). Ram control circuit (E) controls a ram (52, 54, 56) which deploys and retracts mast (12). Jack pressure control circuit (D) senses the pressure on jacks (142a, 142b, 142d) at the four corners of the vehicle. Jack leveling logic circuit (C) receives pressure signals representing the pressure on the jacks and controls extension and retraction of the jacks in pairs at diagonal corners to maintain the vehicle within prescribed leveling conditions and to prevent the over extension or over adjustment under certain unleveling conditions. Mast control circuit (F) receives a signal representing the level condition of the vehicle so that the mast is extended and retracted only under prescribed leveling conditions.
