Abstract: In order to improve efficiency, it always needs to set up several cross cranes in small quarters, and this causes collision possibility between these cranes, so the study of tower crane anticollision system is very important. Based on the embedded Linux, the program of tower crane anticollision system was discussed. Then, based on AT91RM9200,an embedded microprocessor, a monitoring instrumentation host was designed, and realtime detection of every cranes working status was realized, such as gravity, torque, range, height, rotation angle and wind speed, etc.. Then, the interaction of correlated cranes operating status information using wireless transmission was realized. Depending on the algorithm of anticollision, the system controlled the output of cranes to achieve the goal of preventing the collision of cranes. The results indicate that this program has the advantages of strong processing ability, strong realtime ability, and friendly user interface, etc..
Key words: anticollision of tower cranes; embedded Linux; wireless transmission
