Effect of buffer register in the elevator

     Buffer register called the buffer, the input buffer and output buffertwo. The former is the role of the peripheral sent data is stored temporarily, so that the processor will pick it up; the latter is used to temporarily store data to the peripheral processor. Because [1] is connected to the data bus buffer, it must have the function of threestate output.

     Elevator

    The buffer is the last link of elevator safety system, fault or accident to buffer squatting bottom in the elevator appeared. In order to ease the elevator or the people on the elevator from direct impact.

Elevator buffer is divided into: hydraulic buffer, buffer springs andpolyurethane buffer, wherein the hydraulic buffer due to the velocity of various tonnage requirements are widely used, spring buffer for low speed elevator.
