【摘要】：近年来,由于燃气市场的开放和能源的短缺导致燃气价格的波动频繁,无论是燃气公司还是普通用户都希望能有更精确、更灵活的燃气计价方式。同时,燃气计量技术和计量设备的飞速发展,加上国内各地燃气的发展和使用情况的差异,使得膜式燃气表、脉冲计量燃气表以及配备各种流量积算仪的燃气表等在国内长期共存。从而导致了这样一个现象:虽然燃气表主要功能相差无几,但由于计量方式的不同,燃气表制造公司仍然需要根据用户计量需求不断开发不同的燃气表控制器。本文针对这种情况开发了一种可适配多种计量设备的智能远传燃气表控制器。主要工作和成果如下:1.控制器系统由可独立工作的实现计量适配的计量板、实现GPRS远程通信功能的远传通讯板和负责燃气表公共控制功能的主控板三个模块组成。将传统膜式表计量、脉冲流量计计量以及流量积算仪计量电路集成到了计量板上,使其能适配多种计量设备。2.在系统软件开发中,设计了智能燃气表控制器各模块的嵌入式底层程序,配合硬件实现了燃气表控制器的稳定工作。3.计量板与主控制板之间采用Modbus协议通信。控制器和远程管理中心之间通过GPRS网络进行远程通信。根据燃气表功能需求和各模块性能特点,设计了主控板与计量板之间、控制器与后台管理中心之间的通信协议,解决了系统的通信问题。论文对整个燃气表控制器进行了集成测试,测试结果表明在系统硬件和软件协同工作下,可实现燃气表多计量方式的适配。论文的最后对全文进行了总结,并分析了系统一些不完善的地方,对设计的后续优化作出展望。
[Abstract]:In recent years, due to the opening of gas market and the shortage of energy, gas prices fluctuate frequently, both gas companies and ordinary users hope to have more accurate and flexible gas pricing methods. At the same time, the rapid development of gas metering technology and metering equipment, coupled with the differences in the development and use of gas in various parts of the country, make the membrane gas meters, Pulse gas meters and gas meters equipped with various flow integrators coexist in China for a long time. As a result, although the main functions of the gas meter are almost the same, because of the different metering methods, the gas meter manufacturing company still needs to develop different gas meter controllers according to the needs of the users. In this paper, an intelligent remote gas meter controller is developed for various metering devices. The main work and results are as follows: 1. The controller system consists of three modules: the metering board which can work independently, the remote communication board which realizes the remote communication function of GPRS and the main control board which is responsible for the common control function of gas meter. The metering circuit of traditional membrane meter, pulse Flowmeter and flow integrator is integrated into the metering board to make it suitable for various metering equipments. In the software development of the system, the embedded bottom program of each module of the intelligent gas meter controller is designed, and the steady operation of the gas meter controller is realized with hardware. 3. The communication between the metering board and the main control board is based on Modbus protocol. The remote communication between the controller and the remote management center is carried out through the GPRS network. According to the function requirement of the gas meter and the characteristics of each module, the communication protocol between the main control board and the metering board, the controller and the background management center is designed, and the communication problem of the system is solved. The integrated test of the whole gas meter controller is carried out in this paper. The test results show that the multi-metering mode of the gas meter can be adapted under the cooperation of the hardware and software of the system. At the end of the paper, the paper summarizes the whole paper, analyzes some imperfections of the system, and makes a prospect for the following optimization of the design.
