Cable node starting control method and system based on time period

The embodiment of the invention discloses a cable node starting control method and system based on a time period, and the method comprises the steps: obtaining a node configuration table and a set node selection strategy, and enabling the node configuration table to record the node identification and node position of each sensor node in a preset region; determining the number of reported nodes according to the current time period; and selecting the sensor nodes with the node reporting number in the node configuration table based on the node selection strategy, and starting the selected sensor nodes. According to the scheme, the node reporting number is determined according to the current time period, and the sensor nodes with the node reporting number are selected from the obtained node configuration table based on the obtained node selection strategy and are started, so that under the condition of ensuring the stability of cable monitoring, the node power consumption is reduced, the transmission bandwidth is
