论文在深入了解了国内外智能检测系统发展的基础上，根据煤矿井下的实际环境，认真分析了传统的圆图压力记录仪的缺点与不足，开发出了智能压力检测系统的压力测试仪以及PC机数据处理软件。 本论文所研制的压力测试仪是微计算机与仪器的有机结合。它是以AT89C52单片机为核心并外接其它芯片的计算机系统。该测试仪的主要特点是：测量量程为0～60Mpa，精度为1％；每5分钟采集一次两路通道液压压力值；采用“数据融合”技术进行温度补偿；数据容量大，能存放约13天的压力数据；LED显示器可交替显示两路压力值；无线数据通信功能，传输速率为9600kbps；采用本安设计，可安全的应用于环境复杂的煤矿井下。 本论文所设计的上位机数据处理软件可以通过串口读取压力手抄器中的压力数据，经过处理后保存于数据库中，并能以报表和曲线图的形式打印出来，便于统计和查阅，而且实现了访问、查询和编辑数据库中的记录等功能。

On the basis of the deep research on the progress of national and international intelligent measuring system, with carefully studying the shortcomings of the mechanical hydraulic measure instrument, the press instrument and the data processing software for PC in the intelligent measuring system have been designed according to the actual environment in the paper. The intelligent press instrument was a combination of microcomputer and instrument. It was mainly made of AT89C52 and other peripheral chips. The press instrument has many advantages, for example the measure range is 0~60Mpa, the precision is one percent, and the hydraulic press of two roads was sampled every five minutes. This system makes use of the “data fusion” technique to compensate measuring errors caused by temperature changing. The press instrument has large storage space and can store about thirteen day’s press data. Press data can be displayed by the LED display and transmitted to the portable press collector by wireless communication at a bit rate of 9600kbps. With the design of essential safety circuit, the press instrument can be used in coal mine safely. Besides reading press data from the portable press collector through serial port, processing press data and putting data into the database, the data processing software for PC can print data in report and graph forms. The software can also visit, query and edit the records in the database.
