The invention discloses cable channel map display method applicable to a mobile terminal, including steps of 1), classifying data to be displayed, and then establishing a data sheet for every type and storing the data; 2), analyzing data, acquiring the topological relation between the data, and then establishing a topological relation table and storing the topological relation; 3), judging a device or an appliance corresponding to the data in every data sheet, and matching the data with corresponding primitive; 4), according to the actual coordinate of the device, matching the primitive with the map and displaying on the map. According to the method, all data is classified, and one primitive can display on the map for many times as required; the resource space is small, and more spaces can be cleared to store the device state information; thus data is more plump, and data access speed is also guaranteed; moreover, the map displayed by the method is clear in image and exact in information.
