Title: System and method for managing operations on a peripheral surface of a building

Description:
FIELD OF THE INVENTION 
     The present invention generally relates to managing operations on a peripheral surface of a building. More specifically, the invention relates to a system for managing operations such as, fire fighting, rescue operations and maintenance operations on the peripheral surface of the building. 
     BACKGROUND OF THE INVENTION 
     Nowadays performing rescue and fire fighting operations at locations above the ground level remains tedious especially, when a location for such operations is high above the ground level. Additionally, maintenance of high rise buildings is also a time consuming and risky. 
     In existing technologies, helicopters are used to perform rescue and fire fighting operations on the high rise buildings. Helicopters may use one of ropes, cages, ladders, and baskets for performing rescue and fire fighting operations. However, the use of ropes, cages, ladders, and baskets involves considerable amount of risk due to the dynamics of the helicopters. Additionally, the dynamics of the helicopters results in movement of hanging cages and hanging baskets. The movement of the hanging cages and the hanging baskets may create height and space limitations. 
     Further, elevators may also be used to overcome the above limitations. The elevators can be installed on an exterior wall of a multi-storey building. Alternatively, the elevators may be installed in the ground level and may be used to access different stories of the building. However, the elevators have various limitations. For example, the elevators installed at the ground level cannot be used to access stories of the building that are very high above the ground level due to height limitation of the elevators. Further, the elevators installed on the exterior wall of the multi-storey building may not be able to navigate across entire peripheral surface of the multi-storey building. Further installation of such elevators may be challenging when the shape of the multi-storey building is irregular and may be costly affair. Moreover, during a severe fire outbreak, an assembly holding the elevators may get damaged. 
     Apart from the above mentioned technologies, suspended pulley mechanisms may be also used for rescue operations, fire fighting, and maintenance operations. The pulley mechanism may used to hold a rope along with a cage. The pulley mechanism may installed on a top portion of a high rise building thereby enabling the rope along with the cage to be suspended from the building. However, the cage suspended using the pulley mechanism may become unstable. 
     Therefore, there is a need for a system for managing operations on a peripheral surface of high rise buildings in an efficient manner.

Further, the one or more wheeled device may also be capable of moving multiple directions on the peripheral surface. This is achieved using a steering mechanism present in a wheeled device of the one or more wheeled device. This is explained in detail in conjunction with  FIG. 1 . 
       FIG. 8  illustrates a flow diagram of a method for positioning one or more wheeled devices of one or more assemblies on a peripheral surface of a building. The one or more wheeled devices may be positioned on the peripheral surface by controlling the tension in the one or more cables connected to the one or more wheeled devices. The one or more wheeled devices along with the one or more cables are capable of moving on the peripheral surface. While moving on the peripheral surface, the one or more wheeled device may face obstacles and may need to move on the peripheral surface having different profile for example, an inclined peripheral surface. In such instance, the one or more cables of the one or more wheeled devices may need to be adjusted to overcome the obstacles and for accommodating the different configurations of the peripheral surface. 
     At step  802 , one or more wheeled devices of an assembly are loosely positioned on the peripheral surface of the building. The one or more wheeled devices are loosely positioned by relaxing a cable of the one or more cables of the assembly. Further, one or more wheeled devices of an adjacent assembly are tightly positioned on the peripheral surface of the building at step  804 . The one or more wheeled devices of the adjacent assembly are tightly positioned by tightening a cable of the one or more cables of the adjacent assembly. Thereafter, at step  806 , one or more wheeled devices of the assembly are angularly moved away from the peripheral surface of the building. This enables the one or more wheeled devices to overcome the obstacles on the peripheral surface. Further, by tightening and relaxing the one or more cables, the one or more wheeled devices may be capable of accommodating the profile of the peripheral surface. This is explained in conjunction with  FIG. 4 ,  FIG. 5  and  FIG. 6 . 
     Various embodiments of the invention provide system for managing operations on a peripheral surface of a building. The system efficiently performs rescue, fire fighting, and maintenance operations on high rise buildings. Further, a wheeled device of the system is capable of movement on a peripheral surface of the high rise building. The movement of a wheeled device of the system can be initiated from any storey of a multi-storey building. The system requires minimal manual intervention for managing operations on the peripheral surface of the building. In addition, the system disclosed for managing operations on a peripheral surface of high rise buildings is economical.
