The present invention relates to an energy saving water impact prevention system detecting water impacts, which prevents needless energy consumption, and to a method for controlling same. In the water impact prevention system according to the present invention, the amount of change in water level in an air chamber is detected by a plurality of contact switches or a level sensor unit and the amount of change in pressure detected by a pressure sensor unit are transmitted to a controller, and the controller detects whether there is water impact by deciphering through a reference value and a set value input through a control panel, and controls an air compressor and an exhaust valve to reduce water impact in a main pipe. A plurality of pumps capable of controlling the capacity of the main pipe according to changes in the user environment is selectively turned ON/OFF. The controller decides on a 'normal mode' when the amount of change in water level, ∆H, and the amount of change in pressure, ∆P, transmitted by the pressure sensor unit and the level sensor unit fall within reference value ranges (±Hr, ±Pr) over a set time T, decides on 'safe mode' when the amount of change in water level, ∆H, and the amount of change in pressure, ∆P, fall within set value ranges (±Hs, ±Ps) over the set time T, uses the respective set values to operate the exhaust valve and the air compressor connected to the air chamber during 'normal mode' or 'safe mode', and operates the exhaust valve or the air compressor only when 'safe mode' is departed from in order to control the water level and pressure in the air chamber. The present invention detects a sudden water impact when the pressure exceeds the set value range and there is a sudden change within a set time and stops the operation of the air compressor and the exhaust valve to protect the system and generate an emergency alarm, and prevents the air compressor and the exhaust valve from needlessly switching ON/OFF repeatedly when a normal water impact occurs so as to save energy. Thus, through automatic feedback control, response time for water impact is not needed, and water impacts can be prevented in real time.
