【正文】 Abstract Using the infrared emission, accept module for counting sensor based on the photoelectric detection principle, design of infrared electronic counters. For the passengers into out count more convenient and quick. Because the device using modular structure and encryption, decoding, solve the technical problem. Antiinterference So stable count accurately. Can be widely used in automobiles record into the number of devices.
