资料介绍

在煤自然氧化过程中不同阶段会产生不同浓度的成分气体,据此设计并实现了多传感器测量系统,选用红外二氧化碳传感器、电化学式一氧化碳传感器、原电池式氧气传感器、红外瓦斯传感器和数字式温湿度传感器作为测量元器件。根据行业标准设计了各传感器的测量电路,保证传感器数据的可靠性;系统采取模块化设计思路,方便后期的升级和扩展;测试结果表明系统满足煤炭相关行业标准要求。该系统对于定量研究煤的自燃,以及煤自燃的预测都有一定的实践价值。

During the natural oxidation of coal,different concentrations of component gases will be generated at different stages,based on this, we design and implement a multi-sensor measurement system. The infrared CO2 sensor,electrochemical carbon monoxide sensor,primary cell oxygen sensor,infrared gas sensor and digital temperature and humidity sensor were selected as measuring components. Measurement circuits for each sensor are designed according to industry standards to ensure the reliability of sensor data. The system adopts a modular design concept to facilitate later upgrade and expansion. The test results show that the system meets the requirements of coal-related industry standards. The system has certain practical value for the quantitative study of spontaneous combustion of coal and the prediction of coal spontaneous combustion.
