Method, device and system for reducing consumption of road side unit equipment

The invention relates to a consumption reduction method, device and system for roadside unit equipment, and the method comprises the steps: obtaining the speed and position of each vehicle in the current coverage range of the roadside unit equipment; according to the vehicle speed and the position of each vehicle, determining a corresponding future predicted sleep period and a future predicted working period; solving intersection of the future predicted sleep periods, and determining a corresponding total predicted sleep period; solving a union set of each future predicted working period, and determining a corresponding total predicted working period; and controlling and adjusting the operation state of the roadside unit equipment according to the total predicted sleep time period and the total predicted working time period. According to the method, the roadside unit equipment can operate at low power consumption in the sleep period obtained through calculation before the vehicle enters the coverage range of
