DDF (database definition file)-based sensor value monitoring method

The invention provides a DDF (database definition file)-based sensor value monitoring method. The concrete realization process of the method comprises the following steps: designing a DDF, wherein an XML (extensive markup language) format is adopted as the file format; configuring basic parameters of a sensor chip into the DDF; initializing a sensor value; configuring the address information of an I2C (inter-integrated circuit) bus, wherein the address information is used for reading the sensor value; starting up to finish the initialization of the sensor chip; feeding back read sensing data into case management software by an ARM (advanced Risc machines) processor through the sensing data of an addressing chip of the I2C bus to perform case management. Compared with the prior art, the DDF-based sensor value monitoring method provided by the invention is capable of performing the case management according to the acquired parameters, such as a voltage value and a temperature value, and therefore, the monitoring of the complete machine running status of a server is realized; the DDF-based sensor value monitoring method is high in practicability, broad in application range and easy to popularize.
