The invention discloses the realization method of an impact electric field measurement system based on a wireless local area network. The method comprises the following steps of A, placing a measuringelectrode in an electric field to be measured and generating inductive charges on a surface; B, converting the inductive charges into an induction voltage; C, amplifying the induction voltage; D, collected the amplified induction voltage and converting into a digital signal; and E, sending the digital signal to a terminal through the wireless local area network. The wireless local area network isused to transmit data so that problems of a large transmitted data size and poor real-time performance can be solved, and measurement accuracy is increased.
