The invention provides an information collection and monitoring device with a long-time blanking function, and belongs to the field of information collection. A horizontal movement and control system comprises a plurality of air spraying control valves and a compressed air pipeline system, wherein the air spraying control valves are multi-path reversing valves, are respectively arranged in an air spraying device and are connected with a control system and an compressed air pipeline system; whether each air spraying device sprays air or not, and the air spraying direction and the air spraying quantity of each air spraying device can be controlled; the compression air pipeline system is arranged between the air spraying device and a compressed air storage device through a gas distribution valve; the compressed air pipeline system consists of a pipeline and a connector; the compressed air pipeline is made of light-weight pressure-resistant materials. The information collection and monitoring device has the characteristics that the long-time continuous observation on a certain region can be maintained; the corresponding information can be collected; the manufacturing and operation cost is low; the information obtaining precision is high.
