The invention provides a multilaser-action surveillance inquiry method and a multilaser-action surveillance inquiry system. The inquiry method comprises the steps of 1. receiving a multilaser-action surveillance inquiry control instruction; 2. transmitting received surveillance inquiry control instruction to a multilaser-action surveillance inquiry station; 3. transmitting the multilaser-action surveillance inquiry control instruction, wherein a signal in an A/C mode or a signal in an S mode can be transmitted, and furthermore the inquiry signal in the A/C mode is full-calling inquiry mode, and the inquiry signal in the S mode comprises the full-calling inquiry mode and a selective inquiry mode. In the full-calling inquiry mode, the dispensed inquiry control instruction is randomly assigned to a multilaser-action surveillance inquiry station. In the selective inquiry mode, the multilaser-action surveillance station which is closest to a to-be-inquired target is selected for transmitting the inquiry signal out according to distances between the to-be-inquired target and the multilaser-action surveillance inquiry stations. Therefore, the invention provides the multilaser-action surveillance inquiry method and the multilaser-action surveillance inquiry system for transmitting the multilaser-action surveillance inquiry signal out accurately and timely.
