| Abstract: | The paper states a itinerate detect system with ingle-chip Microcomputer A new methodology of detecting system which application realize linearization photoelectric isolator for single fuel battery is introduced and analyzed in this paper, TLP521-2 can be used to replace the precision linear photoelectric isolator LOC 110 or LOC 111 in isolating DC voltage. Analyses its hardware and software. The experiment proves that the system offers many virtues such as simple structure, high measuring precision, reliable repeatability fine linearity and low cost and this system has warning and communication with PC. |
