Anti-collision control device and method for boom cranes

The invention discloses an anti-collision control device for boom cranes. The anti-collision control device comprises a stand-alone control system, a central control system and a wireless communication module. The invention further discloses an anti-collision control method for the boom cranes. The method comprises the following steps that GPS data is uploaded to a stand-alone controller, the stand-alone controller reads a GPS message, extracts longitude, latitude and altitude, and sends the longitude, latitude and altitude to the central control system through the wireless communication module; the central control system calculates the position relation between the two boom cranes, and if the distance between the two boom cranes is smaller than the sum of the boom lengths of the two boomcranes, it is judged that the two boom cranes interfere with each other; the central control system transmits data which interfere with each other to the corresponding stand-alone control system; andthe central control system
