The invention provides a mobile group intelligent perception excitation method with minimized payment as an object. The method solves a problem of minimized payment on the premise that all tasks are completed in a mobile group intelligent perception application, so as to save perception cost for an employer. The method comprises: firstly, providing a group intelligent perception reverse auction model based on time window, providing a polynomial time excitation algorithm based on the model, the algorithm including two steps of primary selection and weight competition, in the primary selection step, using a minimum-cost maximum-flow algorithm to obtain two groups of non-intersected users, in the weight competition step, using a graph theory to find substituted user groups, and according to cost with weight, selecting final selected users, and calculating remuneration of each user. Compared with other excitation mechanisms, the method has lower total amount paid, and is still individually rational and anti-cheating.
