摘要: 在城市化进程不断加快以及天然气与能源结构占比持续提升的大背景下，燃气表的精确计量与安全使用对于保障城市供气系统的稳定运行至关重要。当前传统燃气表在流量监测时，易受温度、压力等环境因素干扰，致使计量出现偏差，这给燃气供应的安全性和经济效益带来了不利影响。本文提出基于温度压力补偿的燃气表流量监测补偿及预警控制系统设计。系统选择STM32系列单片机，提出一套颇具创新性的燃气流量动态监控与调控体系架构，通过极其完善多样化的温度感知装置以及压力采集元件，对周遭外部条件悄然持续地进行观测与感应。这些原始数据经过温压矫正算法后，实现燃气体积流速的高精度计算，从而提高计量科学性。在技术实现环节中，方案还嵌入了结构繁复的红外对射模块，对燃气输送过程中模拟运动状态作进一步识别。使用者可利用物理按键，随时切换和设定各项燃气消费阈值，当某项参数出现超计划情况，就会有报警器及时输出声响提醒。关于系统核心数据信息，例如实时温度、当前压力水平与相关预警指标等内容，都通过显示屏直观展现出来。终端还能够直接联动Wi-Fi无线模组，同步把关键运行结果传递到更高级设备或后台主机，为信息互通及管理智慧升级提供连续保障作用。

Abstract: Against the backdrop of accelerating urbanization and the continuous increase in the proportion of natural gas in the energy structure, accurate measurement and safe use of gas meters are crucial for ensuring the stable operation of urban gas supply systems. Currently, traditional gas meters are susceptible to environmental factors such as temperature and pressure interference during flow monitoring, resulting in measurement deviations, which have adverse effects on the safety and economic benefits of gas supply. This article proposes the design of a gas meter flow monitoring compensation and warning control system based on temperature and pressure compensation. The system selects STM32 series microcontrollers and proposes an innovative gas flow dynamic monitoring and control system architecture. Through extremely sophisticated and diverse temperature sensing devices and pressure acquisition components, it quietly and continuously observes and senses the surrounding external conditions. After the temperature and pressure correction algorithm is applied to these raw data, high-precision calculation of gas volume flow rate is achieved, thereby improving the scientificity of measurement. In the technical implementation stage, the solution also embeds a complex infrared radiation module to further identify the simulated motion state during gas transportation. Users can use physical buttons to switch and set various gas consumption thresholds at any time. When a parameter exceeds the plan, an alarm will promptly output an audible reminder. The core data information of the system, such as real-time temperature, current pressure level, and related warning indicators, is visually displayed on the screen. The terminal can also directly link with the Wi-Fi wireless module to synchronously transmit key operational results to higher-level devices or backend hosts, providing continuous support for information exchange and intelligent management upgrades.
