Description
technical field [0001] The invention relates to an electric heating wire wiring technology, in particular to a research field of an electric heating wire arrangement method in a heating sheet of a pipeline heater, in particular to a multi-objective dynamic programming electric heating wire automatic wiring method. Background technique [0002] The heating sheet is the source of heat for the heater, and the arrangement of the heating wires in the heating sheet is a key factor affecting the effectiveness of the heating film. At present, the designers of the enterprise only calculate and select the appropriate heating wire diameter according to the known parameters such as voltage and power, and then obtain the final heating wire wiring diagram through manual attempts and modifications in the drawing software. Such a wiring method not only consumes too much time and manpower, but also cannot guarantee whether the wiring is uniform, whether the utilization rate of the heating wi...
