The invention provides an engineering machine depreciation degree recording device and belongs to the technical field of monitoring. According to the technical scheme, the engineering machine depreciation degree recording device comprises a singlechip microcomputer, a vehicle voltage sensor, a vibrating sensor and a wireless communication module, wherein the singlechip microcomputer is internally provided with a cycle timer, a timer, an accumulated working hour storage device and a rough working hour storage device; the output end of the vehicle voltage sensor is connected with an AD port of the singlechip microcomputer; the wireless communication module is connected with a communication port of the singlechip microcomputer; a 3D (Three-Dimensional) acceleration sensor is adopted as the vibrating sensor; an interruption pin of the vibrating sensor is directly connected with that of the singlechip microcomputer; the data communication interface of the acceleration sensor is connected with the singlechip microcomputer by virtue of an SPI (Serial Peripheral Interface) bus. According to the engineering machine depreciation degree recording device, the influence of vehicle body vibration intensity on engineering machine abrasion speed is fully considered, and the engineering machine depreciation degree is represented by use of modified engine accumulated operational time, so that the engineering machine depreciation degree judgment error is greatly reduced, and reliable reference is provided for evaluating the available value of an engineering machine.
