Embodiment Construction
[0066] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0067] In this embodiment, a 10-channel data logger is used to collect the temperature (with 10 temperature sensors) from the vaccine storage refrigerator, and a total of 60 temperature data collections with a period of 1 s are carried out. The actual temperature of the refrigerator is -9.1°C measured by a standard device. The method of the present invention is used for dynamic temperature fusion simulation to verify the effectiveness of the method of the present invention. The flow process of the inventive method is as figure 1 As shown, the orthogonal basis function neural network model is as follows figure 2 shown. The invention includes: elimination of negligent errors based on correlation function sorting, multi-sensing temperature information fusion based on orthogonal neural network, invalid sensor variance and mean value correction.
