摘　　要：针对金属锂-亚硫酰氯电池在民用工业和军事工业应用过程中存在电解液泄漏的风险,应用软测量技术,通过检测电池舱内的温压变化信息,建立泄露检测模型,并以该模型为基础设计电池舱电解液泄漏监测系统.当电解液发生泄漏时,进行泄漏报警,同时得到泄漏量和泄露位置,并利用LabVIEW为软件开发平台,开发实时监测界面,在线监测电池舱电解液泄漏情况,实现传感器失效报警、高温报警和高压报警.经测试,该方案能实现实时在线监测电池舱中电解液泄漏情况.实验结果表明,该监测系统运转良好,适用于密闭空间中气体、液体泄漏的监测.Metallic lithium-thionyl chloride battery has the risk of electrolyte leakage in civilian and military industry.Aiming at this case,we propose a soft-measurement technology to establish a leakage monitoring model by detecting the change of pressure and temperature in battery tank.Based on the above model,we have designed an electrolyte leakage monitoring system.When the electrolyte leakage occurs,the system could alarm and reveal the amount and location of leakage.We also have designed a real-time monitoring interface to monitor the leakage of the electrolyte in the battery tank on line.Therefore,the sensor failure alarm,high temperature alarm and high-pressure alarm could be achieved.This scheme could monitor the real-time leakage of electrolyte online in the battery compartment.Experimental results show that the monitoring system works very well and has wonderful application prospects of monitoring the leakage of gas and liquid in confined spaces.
