The application relates to a positive and negative ion balance control method for electrostatic elimination, and belongs to the technical field of electrostatic elimination. The method solves the problems of poor adaptive adjustment capability, weak environmental adaptability, insufficient electrostatic elimination efficiency and stability of positive and negative ions in the prior art. The method comprises the following steps: collecting positive and negative ions in a device environment, and obtaining ion voltage signals through signal processing; sampling the ion voltage signals at a set period, generating two control signals of each period through an adaptive balance model; in each period, generating two high-voltage driving power supply voltage signals according to the corresponding two control signals, and then generating corresponding driving high voltage based on the two high-voltage driving power supply voltage signals; and driving the discharge needle to release positive ions and negative ions into the device environment based on the driving high voltage of each period, so as to realize electrostatic elimination. The method realizes reliable and efficient electrostatic elimination.

To provide an ion balance sensor and a static elimination system capable of grasping further information regarding an environment of a target space in addition to ion balance in the target space. The ion balance sensor includes a detection plate that is conductive and arranged in a target space. In the ion balance sensor, ion balance in the target space is detected based on a potential of the detection plate. An ion balance signal indicating a detection result is generated. Further, a physical quantity related to an environment of the target space is detected in addition to the ion balance. Another signal indicating information regarding the environment of the target space is generated based on a detection result. The ion balance signal and the other signal are output.
