The child safety seat according to claim 10, wherein: the detecting element (2) in the second detection area further comprises a plurality of pressure sensors for detecting pressure, the sampling circuit (3) receives pressure values output by the pressure sensors and compares the pressure values with preset threshold values, when the pressure value of a certain point or a certain area position is higher than the threshold value for a long time, a fifth control signal is output to the warning device, and the warning device sends a fifth warning sound after receiving the fifth control signal output by the sampling circuit (3) and is used for reminding a user that the sitting posture of children is incorrect, uncomfortable or reminding a designer that the position of the point or the stress of the area position is too large and the design needs to be changed.
12. A child safety seat according to any of claims 8 to 11, wherein: the fabric sensor on the seat body further comprises a resistance-type sensor element for detecting temperature, a temperature signal output by the resistance-type sensor element is used for correcting the value of the physical characteristic detected by other sensor elements on the seat body, which are influenced by the temperature, comparing the corrected value of the physical characteristic with a threshold value, and then outputting a corresponding control signal to the warning device.
