With the continuous application of location technology, ultra-wide band (UWB) location as a typical representation of indoor location technology is developing rapidly. It possesses many excellent features and performs well in UWB/INS integrated navigation system. Therefore, this paper investigates the UWB/INS integrated navigation method with fuzzy Kalman filtering algorithm in the case of existing large fluctuation caused by non-line-of-sight (NLOS) factors to meet the requirements on high location accuracy of electrical apparatuses in the complex indoor environment.This paper presents the fuzzy Kalman filtering algorithm by theoretical derivation and algorithm flow chart, and then carries out related simulation experiments to show and analyze the comparison results of the original algorithm and the modified one by using fuzzy control. The comparison of error curves indicates that the improved algorithm can effectively deal with the non-line-of-sight interference, and make sure the location data smoother and more reliable. This method is helpful to improve the location of electrical apparatuses.

The stratified air conditioning systems are widely used in large space buildings. Stratified air conditioning load (SACL) is the basis for determining the cooling capacity of air conditioning system, and it is also the key to assess its energy savings of stratified cooling. Calculation of the radiant heat transfer load (RHTL) is the difficult point to determine the SACL. In recent years, there have been many researches on the calculation of SACL. Most of them are steady-state calculation processes, and there are few studies on dynamic calculation processes. Therefore, the RHTL is taken as the research object, a novel calculation method is proposed according to the harmonic reaction method (HRM) and verified by the experiments. Experimental radiant heat transfer load can be received through convection and radiation separating method. The experimental and theoretical values of RHTL were compared and it was found that the theoretical values were in good agreement with experimental values. Therefore, the proposed method can be used to predict the unsteady RHTL accurately. Based on the verified calculation method, the effects of outdoor climatic conditions, building types and stratified heights on RHTL of an actual large space building are analyzed, which will contribute to the design and optimization of stratified air conditioning system for large space buildings.

The existing ERP system of the existing enterprise management system so that the management level to stay in the local network level, cannot form information exchange with the outside world, hinder the interaction between enterprises inside and outside the network information, the author proposed a based on the Internet plus and cloud platform progress monitoring system, taking full account of the internal and external network data transmission based on the security, filtering the enterprise sensitive information, in order to achieve data entry, progress query and early warning three functions.
