The invention provides a control method, equipment and system of an illumination lamp group, and storage equipment. The illumination lamp group comprises a plurality of illumination lamps. The plurality of illumination lamps are arranged in one work area. The control method comprises the following steps of acquiring the busy-degree numerical value of the work area; comparing the busy-degree numerical value with a first busy threshold and the busy-degree numerical value with a second busy threshold, wherein the first busy threshold is less than the second busy threshold; if the busy-degree numerical value is less than or equal to the first busy threshold, making all the illumination lamps in the illumination lamp group be turned off; if the busy-degree numerical value is greater than the first busy threshold and is less than or equal to the second busy threshold, controlling parts of the illumination lamps in the illumination lamp group be turned on; and if the busy-degree numerical value is greater than the second busy threshold, making all the illumination lamps in the illumination lamp group be turned on. Based on the above method, according to a work condition, the on and off condition of the illumination lamps is controlled so that effects of prolonging the service lives of the illumination lamps, distributing work resources and reducing work cost are achieved.
