The application provides a method and apparatus for evaluating the transmission data uncertainty of a power grid safety operation communication device. The method includes the steps of generating a plurality of pseudo-random numbers uniformly distributed over an interval of [0,1]; collecting a variety of power grid safety operation parameter measured data by using a multi-mode wireless communication device, and determining the probability distribution of each parameter according to each parameter measured data; performing random variable sampling on the probability distribution of each parameter according to the pseudo-random numbers to obtain multiple simulated measurement data of each parameter; and calculating the standard deviation of the multiple simulated measurement data for each parameter to obtain the uncertainty of each parameter. The method and apparatus in the application can evaluate the uncertainty of the data transmitted by the multi-mode wireless communication device, that is, the degree of uncertainty of the result measured by each sensor (connected to the multi-mode wireless communication device) can be evaluated, reflect a lack of understanding of the measured truth-value, and provide a basis for the fault simulation of subsequent measurement results.
Description
technical field [0001] The present application belongs to the technical field of wireless communication, and in particular relates to a method and device for evaluating uncertainty of data transmitted by a multi-mode wireless communication device in the safe operation of a power grid. Background technique [0002] For the development of data communication devices for power grid safety operation at home and abroad, from the initial 80s with 8051 microcontroller as the core chip and 485 serial ports as the communication form, it transitioned to around 2000 with TMS320 series DSP chips, ARM7 and other low-end chips as the core, 485 Serial port, optical fiber cable network, and GPRS are the mainstream forms of communication technology, and ARM11, STM32, MK60FN, etc. will be the core chips around 2015, and wireless communication terminals in the form of multi-mode wireless communication such as GPRS, Wifi, 4G, and Mesh. Fundamentally speaking, the upgrading of wireless communicat...
