The invention relates to the technology of substation equipment contact temperature analysis and early-warning, in particular to a substation equipment contact state analysis and early-warning star network platform. The substation equipment contact state analysis and early-warning star network platform solves the problem that an existing substation equipment contact state temperature analysis and early-warning platform is unstable in transmission and poor in transmission reliability. The substation equipment contact state analysis and early-warning star network platform comprises collection layers, a transmission layer and an early-warning layer: each of the two collection layers comprises m SAW temperature sensors, m normal minor spiral antennas, a spiral arm dipole antenna and a wireless temperature collector, and the m normal minor spiral antennas and the spiral arm dipole antenna jointly form a star topological structure; the early-warning layer comprises an analysis and early-warning work station, two coaxial cables, a sound and light alarm, a Bluetooth adapter and n mobile phones, wherein the n mobile phones and the Bluetooth adapter jointly form a star topological structure. The substation equipment contact state analysis and early-warning star network platform is suitable for substations.
