Equipment life prediction method and device and constant-temperature acceleration test system

The embodiment of the invention provides an equipment life prediction method and device and a constant-temperature acceleration test system, and belongs to the technical field of equipment reliability prediction. The equipment service life prediction method comprises the following steps: acquiring an initial working temperature corresponding to an initial constant temperature and a first working temperature corresponding to a first constant temperature of each component on each circuit board card in equipment; based on the activation energy, the initial working temperature and the first working temperature of each component, the speed-up ratio of each component is determined; according to the speed-up ratio and the failure rate of each component, the speed-up ratio of the equipment is determined; and predicting the service life of the equipment according to the test duration from the time when the equipment is subjected to the constant-temperature acceleration test at the first constant temperature to the tim
