The invention discloses a network voltage detection device, method and system and electronic equipment, and relates to the field of train power supply. The device comprises a voltage transformer, a direct current detection device and a control device, the voltage transformer is used for collecting AC signals of the contact network, and the DC detection device is used for collecting DC voltage signals of the contact network. And the control device is used for controlling a power supply circuit of the train according to the alternating current signal and the frequency acquired by the voltage transformer and/or the direct current voltage signal acquired by the direct current detection device. Therefore, the power supply circuit of the train is controlled by collecting the voltage detected by the voltage transformer and the direct current detection device, automatic detection and switching of the network suppression type signals are achieved, and therefore the reliability and safety of the system are improved, an
