PURPOSE: A building wall cleaning apparatus capable of coping with unevenness on the outer wall surface of a building is provided to prevent recontamination of a raised portion by descending at constant speed along the raised portion. CONSTITUTION: A building wall cleaning apparatus comprises an arm unit(12) which is extended from the backside of a wiper member(10) and coupled with a moving member(11) to move the wiper member toward or back from the outer wall of a building, and a guide member(21) which is integrally installed on the front side of a body(20). The moving member is locked vertical to the guide member and moved relative to the guide member when contact of the wiper member to a raised portion is detected.

PURPOSE: A scavenger for an outer wall of a building with a cross-shaped guide member using relative movement structure is provided to prevent a cleaned part from being polluted again. CONSTITUTION: A scavenger for an outer wall of a building with a cross-shaped guide member using relative movement structure comprises a relative movement assembly. The relative movement assembly comprises a case member, a vertical guide member(31), a horizontal guide member(33), a moveable member(32), a horizontal rail, and a vertical rail(330). The horizontal guide member crosses the vertically guide member with an interval and is horizontally placed. The moveable member is coupled with the vertical guide member and the horizontal guide member. The moveable member relatively moves along the vertical guide member or the horizontal guide member. The horizontal rail is formed in the case member. The horizontal rail is coupled with both end of the vertical guide member to enable the horizontal movement of the vertical guide member. The vertical rail is formed in the case member and is coupled with both ends of the horizontal guide member. The vertical rail enables the horizontal movement of the horizontal guide member.

PURPOSE: A clustering method for a sensor network is provided to efficiently select a cluster head in an energy consumption point of view. CONSTITUTION: Each sensor node transmits consumed energy quantity information for a predetermined period to a BS(Base Station)(S110). The BS determines a probability value(S130). The probability shows the possibility that each sensor node is selected as a cluster header. Each sensor node selects a random value for the comparison with the probability value(S140). By the comparison result between the random value and the probability value, it is determined the each sensor node is selected as the sensor node(S150~S170).

PURPOSE: A building wall cleaning apparatus using a relative moving structure for coping with a raised portion on the outer wall surface of a building is provided to prevent unwanted stop of work by continuously descending along the outer wall of a building even when meeting a raised portion. CONSTITUTION: A building wall cleaning apparatus comprises a body(20) which vertically descends, facing the outer wall of a building, a wiper member(10) which is provided on the front side of the body, facing the outer wall of the building, and contacts the wall surface according to the movement of the body to rake up materials attached to the water surface, and relative movement assemblies(30) which are provided to face each other from both sides of the body and allow relative movement between the wiper member and the body.
Abstract:
A system and a method for monitoring slope failure are provided to monitor a slope collapse in real time by installing a remote sensor for a slope collapse through local wireless communication. A plurality of sensor nodes(100) are installed at a slope collapse risk region by a network structure including a mesh, a star, a triple. Each sensor node has a sleep mode and a wake up mode, and each sensor node produces an index displacement, an underground displacement, and excellence sense information. A sink node(200) processes the index displacement of the sensor node, the underground displacement, and excellence sense information through the local area wireless communications signal. A gateway processes the index displacement, the underground displacement, and excellence sense information as a mobile communication signal.
