Based on neural network decoupling control of variable air volume system
Network structure shown in Figure 3. Adjust the weights of the network driven by the amount of entry rules and adaptive step length improved BP algorithm. Volume 4 will produce electrical machinery induced current circle: After A / D converter circuit, the analog to digital high-low electric current, town triggered by the corresponding microcontroller port. Microprocessors ATmega8I microcontroller, 8-bit CPU and the system on a programmable chip F1ash integrated, powerful, many embedded control applications for the flexible and cost effective solution Figure 3 Figure 3 system software block diagram for the main program application diagram. Microcontroller port configuration flexibility, small change by the external circuit, precision and stability, through software programming, can be visually determine the polarity of CT, and the flexibility to be extended. 3 Conclusion microcontroller-based current transformer polarity tester, from the traditional testing model. The field test, for all the current transformer, just a tester to complete the polarity test for D, and also has a small size, light weight, portable, easy to operate, safe and reliable test, with the promotion of greater value.
