Portable Electrical Equipment Research And Design Of Digital Inspection Instrument

In recent years, with the development of modern information technology&China’s industrial modernization, sustained and rapid economic growth, the demandfor rail transport is becoming more and more. To Improve transport efficiency andensure the safe rail transport of all the equipment, its direction is fixed in theimplementation of information technology and information management. Informationtechnology of railway equipment has made some progress, but management ofinformation technology still can not meet the site’s needs. Railway equipment has thecharacteristics of wide geographical distribution&maintenance of real-timerequirements. To achieve the purpose of the normal inspection, existing methods isusually relied on human management and supervision. There is often missed or lackof inspection of the phenomenon.The main task is to patrol railway equipment parameters were measured for therecord，and to compare its safety data and, if you exceed the allowable range, then thephysical to the railway equipment repair. At present, the main mode of inspectionrecords is by hand or in written inspection report based. Since the report by hand hassome defects which can not be eradicated, such as the storage environment for betterpaper, report a larger number of large storage space needed, not re-use of paperstatements, high total cost of paper. To meet the monitoring of railway safety statisticsand computer requirements, you need to report data into the computer for the secondtime, seriously affecting the efficiency, increases the probability of generating.In response to these problems, this paper develops a single chip based on thedevelopment of portable electrical equipment inspection instrument, the inspectiontool is mainly used in railway inspection, which can also be used in hotels, gold shopand other intelligent building inspection, as well as hospital records, and so on, toprovide significant savings in manpower and resources to promote the modernizationof information. Logging devices main function is detected by the operator of the datarecords, while records of the operator name, time to achieve the basis of inspectiondata collection and data formats and convert them into electronic storage, to avoid thesecond input to improve data reliability, but also for the management of patrol hasbrought convenience.Firstly, the data transmission based on the principle of electrical equipment, portable data logging devices for several large data transmission path, including thenon-contact IC card and contactless IC card reader data transfer between modules,non-contact IC card reader module and the microcontroller data transmission betweenthe LCD display module and the data transmission between the microcontroller andthe microcontroller and memory data transfer between the SD card; determine themain functional modules; and use KeilμVersion recorder for the development of toolsfor programming microcontrollers operating system.
