    Following is a repost of the public domain make that I posted to net.sources a couple of months ago. I have fixed a few bugs, and added some more features, and the resulting changes amounted to about as much text as the whole program (hence the repost).一个编译器C代码,详见REDME。

  • 基于C8051F930的管道温度压力远程监测系统

       为解决输油管道温度压力参数实时监测的问题,设计了以C8051F930单片机作为控制核心的超低功耗输油管道温度压力远程监测系统。现场仪表使用高精度电桥采集数据,通过433 MHz短距离无线通信网络与远程终端RTU进行通信,RTU通过GPRS网络与PC上位机进行远程数据传输,在上位机中实现数据存储和图形化界面显示,从而实现输油管道温度压力参数的实时监测和异常报警。经实验证明,该系统的12位数据采集精度满足设计要求,漏码率小于1%,正常工作时间超过5个月,能实时有效地监测输油管道的温度压力参数,节省大量人工成本,有效预防管道参数异常造成的经济损失和环境污染。 Abstract:  In order to solve the problems on real-time monitoring of pipeline temperature and pressure parameters, the ultra-low power remote pipeline temperature and pressure monitoring system was designed by using the single chip processor C8051F930 as the control core. The high-precision electric bridge was used in field instruments for data collection, the 433MHz short-range wireless communication network was used to make communication between field instrument and RTU, the GPRS was used by the RTU to transmit data to the PC host computer, and the data was stored and displayed in the PC host computer, so the real-time monitoring and exception alerts of pipeline temperature and pressure parameters were achieved. The experiment proves that the system of which error rate is less than 1% over five months working with the 12-bit data acquisition accuracy can effectively monitor the pipeline temperature and pressure parameters in real time, it saves a lot of labor costs and effectively prevents environmental pollution and economic losses caused by abnormal channel parameters.

    Web technology is not evolving in comfortable and incremental steps, but i s turbulent, erratic, and often rather uncomfortable. It is estimated that the Internet, arguably the most important part of the new technological environment, has expanded by about 2000 % and that is doubling in size every six to ten months. In recent years, the advance in computer and web technologies and the decrease in their cost have expanded the means available to collect and store data. As an intermediate consequence, the amount of information (Meaningful data) stored has been increasing at a very fast pace.

    a Java program that reads in the following values from the standard input device (i.e. Keyboard) and writes its result on the standard output device (i.e. Console/Monitor): Inputs: A: the loan amount in dollars and cents (e.g. 150000.00). r: the net annual interest rate, expressed as an integer (e.g. 10 which means 10%) Y: the number of whole remaining years (for repayment) M: the number of remaining months Output: The program should calculate and output the amount of monthly repayments in dollars and cents as single value (e.g. $840.55)

    Maya Calendar During his last sabbatical, professor M. A. Ya made a surprising discovery about the old Maya calendar. From an old knotted message, professor discovered that the Maya civilization used a 365 day long year, called Haab, which had 19 months. Each of the first 18 months was 20 days long, and the names of the months were pop, no, zip, zotz, tzec, xul, yoxkin, mol, chen, yax, zac, ceh, mac, kankin, muan, pax, koyab, cumhu. Instead of having names, the days of the months were denoted by numbers starting from 0 to 19. The last month of Haab was called uayet and had 5 days denoted by numbers 0, 1, 2, 3, 4. The Maya believed that this month was unlucky, the court of justice was not in session, the trade stopped, people did not even sweep the floor.
