The invention discloses a continuous baby weighing method of a baby incubator. The method comprises the following steps: firstly, constructing a baby scale; secondly, adjusting the baby scale: 1: a, measuring tare weight Wp; b, measuring gross weight Wo; c, calculating a value of weight sampling net weight W at the temperature To; d, calculating a standard weight coefficient Kw; e, sampling the temperature To during calibration; and f, storing data; and 2, determining a temperature compensation coefficient; thirdly, running the baby scale; and fourthly, holding a baby to automatically remove the tare weight. The advantages of the method are mainly as follows: the baby scale adopts a common weighing chip and a common weighing sensor, and a temperature compensation mode through a program written by a single-chip microcomputer enables continuous weighing to be realized and is high in cost performance; and the adoption of a hear dissipation fin arranged on the weighing chip solves a problem that temperature changes are inconsistent when the weighing chip and the weighing sensor stay in a temperature changing environment, and effectively prevents a zero drift problem.
