The display module (7) is used to intuitively display and feedback the push-in progress, resistance value and temperature parameters.
6. A feeding pump control system according to claim 5, characterized in that: The temperature sensor (6) is arranged inside the syringe (2), and the drive module (3), the pressure sensor (4), the position sensor (5), the temperature sensor (6) and the display module (7) are all electrically connected to the control system.
