Fiscal verification device fuel tanker

Constitutes a verification device according to the functions of the test device from the analog output sub-key and data collection part of the chestnut, data analysis and processing part of and certificate output of three parts. Mainly by the structure referred to the main control unit, data processing system software, Speed test platform to simulate the flow, pulse flow simulation test sets,ugg boots günstig, the certificate machine. Through the main control unit to transfer the number of simulated flow test sets, test sets to simulate the flow pulse and certificates machine and printer paper together. Whether the tax-testing device was built with or without pulse generator, the output analog test equipment are used to test a certain way traffic between China and Taiwan computer and test ways to test response procedures to control (1) Analog Output and data acquisition components: the control software, the pulse generator and driver circuit, start, stop signal and driving part of the interface circuit,MBT shoes cheap, stepping motor and drive mechanism, the output part of the data acquisition, power supply and other components. To achieve the tax control device of multiple simultaneous measurements. (2) Data analysis and processing part: the main control unit and data analysis software and other components. (3) certificate to print out parts: the certificate machine,North Faces on sale, printer paper and data transfer software and card components. Fourth, the working principle of the verification device works as follows: when the main control computer was seized and Fiscal authentication devices were seized on tax control device to read the original data, the main control unit sends to the test sets \by the test station 35 - were seized on the flow of tax control device output analog signals. Fiscal devices were seized after receiving analog signals into traffic flow data and storage. Were seized from the main control unit tax control device stored in the flow data were extracted, and the corresponding flow of the original set the standard compared to the value, and the results of calculation and judging. All test data and processing results are stored in the main control unit independent of the library file, certified by the tax control device will automatically generate the data verification certificate. By the interconnection with the main control unit is responsible for Certificate Certificate of machine printed out at any time. As the verification system of the device test software platform Windows9x interface in Chinese, so easy to use,ugg Boots Billig, and easier to find the certificate and certificate printing, as well as the detection devices were seized data. Its working principle is shown in Figure l. V. Introduction of the system software design verification testing procedures is the use of State Revenue principle of \compared to the amount measured by its error. Its realization is the program through the serial communications port interconnected with the test station, test station fuel flow simulation device to send to all tax control fuel flow calibration signal, after the completion of the tax control by the application to read data such refueling devices, data classification error calculated after storage (generated record certificate or substandard products). Since the program uses Microsoft Corporation VisualC + +6.0 compiled a database using Microsoft's DAO database engine can run on Windows9x and WindowsNT3.5 +36 + or later operating system platform in Figure 1, the certification process Inspection at a glance. Program verification device mainly composed of the following modules: (1) System parameter setting mode; (2) test module; (3) certificate printing module; (4) certificates on such distribution inquiries and report printing module. The verification device in the building standards system in the process of analysis and calculation of uncertainty in view of space limitations, will be discussed in another paper. Fiscal device design verification device, through the use of large-scale integrated digital circuit technology, optical technology, microcontroller technology, VisualC + +6.0 DAO programming language and database engine, and the combination of industrial design techniques, can solve the accurate, reproducible, versatile, high-efficiency problems. After repeated tests and comparison tests on hundreds of units in the verification of tax control set, the results demonstrate the high degree of intelligence of the verification device, simple, accurate, stable performance, high efficiency. Performance indicators are met JJ 『F1056 and JJG443-98 requirements of the test device has user friendly; large-capacity data storage; automatic data acquisition and processing; automatically generated test certificate, the original record sheet, statements of substandard products; can test and certificate the same time the print job characteristics such as technology and management help to improve the level of verification. The verification device can be widely used in the work required or transfer a given number of output pulses of the same type of product certification,ugg boots cheap, while further improvement of the verification device, but also for the future, such as the taxi meter tax control, tax control water and gas The first such table test (factory test) provide the means.
