The invention provides an express sorting method and a control device and system. The system comprises multiple recognizers, a computer, a sorting cabinet and a sorting cabinet controller; the sortingcabinet is provided with multiple grid ports; each grid port is provided with an indicator light assembly; each indicator light assembly corresponds to a unique grid port address; the luminescence properties of the indicator light assemblies corresponding to the different recognizers are different; the recognizers generate delivery instructions and send the delivery instructions to the computer;the computer acquires the corresponding grid port addresses according to carried address information in the delivery instructions, and the luminescence properties of the corresponding indicator lightassemblies are acquired according to recognition identifications of the recognizers; and the sorting cabinet controller controls the indicator light assemblies corresponding to the grid port addressesto shine according to the luminescence properties of the indicator light assemblies on the basis of the grid port addresses. The express sorting method and the control device and system have the advantages that the grid port corresponding to the delivery address of the read express is determined to effectively prevent the occurrence of the problem that expresses are delivered into grid ports wrongly by setting a corresponding relationship between the luminescence properties of the indicator light assemblies corresponding to the grid ports of the sorting cabinet and the recognizers.
