This paper proposed a railway wagon anti-theft system based on ZigBee technology. The system was consisted of Handheld device, Router and End device. The Handheld device was mainly used for the configuration of the net and initialization. The Router was used to relay the message between the Handheld device and End device. The End device was a monitoring node. The CC2430 microprocessor was the controller of the system. The magnetic sensor was used to monitor the status of the wagon door. The alarm information would be transmitted to the Handheld device to display and alarm. RFID technology was used to mark the number of train carriages. In addition, GPRS module was used for transmitting the wagon information to the remote PC, and finishing wireless long-distance monitor. The experiments verify the reliability of the system. It is proved that the system has a certain application value.
Generally, the effect of cell image that segmented via the threshold value method is not ideal generally; the found cell boundary cannot conform to the cell edge in the original picture well. In this paper, the threshold value segmentation method is improved; apply the judging criterion of gray level difference maximum interval to be the minimum, and conduct secondary treating on the image, and the image’s segmentation effect is more ideal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
