Design And Study Of Portable Infrared Press Instrument In The Intelligent Measure System

Based on the wide and deep understanding of the study of national and international instruments, according as the actual environment, after carefully studying the shortcomings of the mechanic hydraulic measure instrument, the portable infrared press instrument in the intelligent measure system has been designed and made in the paper. With other peripheral chips, it is mainly made of AT89C55. It can collect, store and display press data. It also can transmit the press data to the host computer to deal with them. So it can completely replace the traditional mechanic hydraulic measure instrument.The portable infrared press instrument includes some function modules in hardware, so it also includes some function modules in software. Each function module works in phase, which can ensure to realize the whole function completely.The portable infrared press instrument has the following characteristics: has small volume and weight and carry easily; use a keyboard to input orders and display the corresponding information on the LCD display for the sake of the user's convenience; has big data capacity and can collect 30 press measure instruments all the data which have stored for a week; show the real-time date and time; communicate through the infrared with speed of 2400kbps; has the intrinsically safe circuit and can be safely usedunder coal mine.
