METHOD FOR DIRECTION LIMITATION AND SYSTEM FOR DIRECTOIN LIMITATION

摘要

A method for direction limitation of a firing system. A first calculating unit controls the firing system and knows direction limitation positions. An elevation of the firing system and a traverse of the firing system are measured. A position of the firing system is calculated in the first calculating unit based on the elevation and traverse. The position of the firing system is calculated in a second calculating unit based on the elevation and traverse. The calculated positions of the firing system are compared with direction limitation positions. It is decided whether the firing system is positioned outside the direction limitation positions. Also, a direction limitation system for a firing system.

1. A method for direction limitation of a firing system, where a first calculating unit controls the firing system and where direction limitation positions are known by the first calculating unit, said method comprising:
measuring an elevation of the firing system, measuring a traverse of the firing system, calculating a position of the firing system in the first calculating unit based on the measured elevation and traverse, calculating the position of the firing system in a second calculating unit based on the measured elevation and traverse, comparing the calculated positions of the firing system with direction limitation positions, and deciding whether the firing system is positioned outside the direction limitation positions.
