Detection method for railway snow melting system output electric parameter

The invention belongs to the electric parameter collection and analysis field, and concretely relates to a detection method for a railway snow melting system output electric parameter. Because a high-precision electric quantity isolation mutual inductor is employed to collect current and voltage data, requirements of a system to collection precision can be met, and the stability of the system can be ensured. A CAN bus communication mode is employed, the Baud rate is 0.5Mbps, and high real-time and reliability of the system are ensured. A module has an optional measuring range scope, an external interface has two modes of internal connection and external connection, usage is simple and maintenance is convenient.
