Traffic signal lamp real-time state detection method, system and equipment

The invention discloses a traffic signal lamp real-time state detection method, system and device, and relates to the field of traffic signal lamp state acquisition. The method comprises the following steps: acquiring electrical parameter data of each signal lamp in each signal lamp group in a target area in real time; the electrical parameter data comprises voltage data and/or current data; the signal lamp group at least comprises a red lamp, a yellow lamp and a green lamp; determining the current state parameter of each signal lamp group according to the electrical parameter data of each signal lamp in each signal lamp group of the target area obtained in real time; the current state parameters comprise the type and the remaining time of the signal lamp in the lightening state. According to the method, the state of the signal lamp is determined according to the electrical parameter data of the signal lamp, the method is not influenced by weather, the state of the traffic signal lamp can be accurately obtain
