International Nuclear Information System (INIS)īar codes similar to those used in supermarkets can be used to reduce the effort and cost of collecting nuclear materials accountability data. Conclusion, the bar code systems improved the patient safety and created green environment. We developed a barcode system of 'Specimens Identify System' through process of reengineering of TRM, used bar code scanners, add sample container instructions, and mobile APP. The sample error rate was 11.1%, because misbranded patient information and wrong sample containers during January to April, 2016. In time and correct sample collection were highly related to patient's safety. Use the Bar Code System to Improve Accuracy of the Patient and Sample Identification.Ĭhuang, Shu-Hsia Yeh, Huy-Pzu Chi, Kun-Hung Ku, Hsueh-Chen At this position the level of accuracy reach 100%. The test results is obtained at ideal position for reading a barcode when a barcode scanner is at 2 cm from the object with 90 degree. The presence system has been tested with several KTM through a variety of distances and positions of the barcode scanner barcode. Management of attendance list using this system allows for optimization of functions of KTM. The presence system is supported by three main components, those are a bar code found on the student card (KTM, a CCD barcode scanner series and a CD-108E computer. This research presents the draft of presence system using bar codes (barcodes as input data representing the attendance. The manual presence system is considered less effective. For example, at a university, data about the level of attendance of a student in a lecture is very important as one of components in the assessment. When adding more ZigBee nodes, the transmission distance can be several thousands of meters long.ĭevelopment of Attendance Database System Using Bar-coded Student Cardĭirectory of Open Access Journals (Sweden)įull Text Available The calculation of the level of attendance is very important, because one indicator of a person's credibility can be seen from the level of attendance. In broad space, every ZIGBEE node can realize 50m transmission with high reliability. Finally, performance of communication is tested by evaluation software Smart RF. And by transplanting the embedded RTOS system LINUX to the MCU, an applying wireless CMOS optics bar code scanner and multi-task system is constructed.

In order to construct the whole wireless optics of bar code system and to ensure its ability of transmitting bar code image signals digitally with long distances, ZigBee is used to transmit data to the base station, and this module is designed based on image acquisition system, and at last the wireless transmitting/receiving CC2430 module circuit linking chart is established. So we put forward the method which uses the matrix evaluation and Read-Solomon arithmetic to solve them. The scan system consists of the CMOS image sensor and embedded chip S3C2401X, when the two dimensional bar code is read, the results show the inaccurate and wrong code bar, resulted from image defile, disturber, reads image condition badness, signal interference, unstable system voltage. By rebuilding the traditional CCD optical bar code scanner, a CMOS code scanner is designed based on the ZigBee to meet the demands of market.

The traditional bar code scanner is influenced by the length of data line, but the farthest distance of the wireless bar code scanner of wireless communication is generally between 30m and 100m on the market. The design of the CMOS wireless bar code scanner applying optical system based on ZigBee
