きる。And the displacement when the passenger gets on the car ii! By reading 1B and calculating the difference between displacement [B and A by computer, the passenger load can be accurately detected.
かご内に乗客がいない時の防振ゴムの変位量を絶えず測
定し、初期歪みを補正しているので、常に、正確な乗客
の荷重を検出するとができ、しかも、無調整とすること
ができる。Since the amount of displacement of the anti-vibration rubber is constantly measured when there are no passengers in the car and the initial distortion is corrected, it is possible to always accurately detect the load of passengers, and there is no need to make adjustments. .

のかごの重量に相当する。Next, the present invention will be explained in detail using the flowchart shown in FIG. For a specified period of time after the call is no longer received,
For example, suppose that three minutes or more have passed (step 2). As a result, the process moves to step 3, detects the displacement amount A of the vibration isolating rubber, and stores this detected amount A in RAM (step 4). Quantity A corresponds to the weight of the car when there are no passengers in car 2.
