Height measurement system

A height measurement system, comprising:

• 1) a first fixed assembly, configured to connect to an external fixing part so that the height measurement system is fixed on the external fixing part for use;
• 2) a head plate, configured to move downwards from the first fixed assembly to the head of a user;
• 3) a second fixed assembly, disposed on the head plate and being movable along with the heat plate;
• 4) a digital tape measure, comprising a mounting assembly and a tape disposed in the mounting assembly, one of the mounting assembly and the tape head being attached to the first fixing assembly and the other to the second fixing assembly;
• 5) a memory storing a standard height value of the first fixed assembly connected to the external fixing part;
• and
• 6) a data acquisition unit, configured to acquire a first tensile length of the tape when the head plate moves from the first fixed assembly to a top of the user's head, and transmitting the first tensile length to the memory, and the memory being configured to calculate the height of the user according to the standard height value and the first tensile length of the tape.
