The invention discloses a method and a system for processing asset information of a collector communication unit, wherein, the method comprises the following steps: a product sequence code SN is usedas an identification code of the collector communication unit; the product sequence code SN is used as an identification code of the collector communication unit. Establishing the asset code of the collector communication unit; Before the collector communication unit is put into use, the identity code and the asset code of the collector communication unit are read, and the corresponding relationship between the identity code and the asset code of the collector communication unit is established. The corresponding relationship between the ID code and the asset code of the collector communicationunit is sent to the master station of the collection system, and the collector communication unit is managed by the master station of the collection system. After the collector communication unit isput into use, the identity identification code of the collector communication unit is read, and whether the identity identification code is updated is judged by the collection terminal; when the ID code is updated, the asset code corresponding to the new ID code is queried by the master station of the acquisition system, and the asset code of the collector and the communication unit is bound.
