摘　　要：袖珍式氯气报警仪是一种个人防护式安全仪器,便于接触氯气的工作人员随身携带,用于监测氯气泄漏。当氯气质量浓度超过报警阈值时,自动发出声、光报警信号。介绍了仪器的工作原理、电路设计、软件设计方法及试验结果。由于采用了温度补偿、测量数据多次叠加平均运算等方法,仪器的测量精度得到了提高,误差小于2%。Pocket Chlorine gas alarm device is individual protective equipment.For workers getting in touch with the Chlorine gas,it is easy to be taken along with,and can be used to detect the leaking of chlorine gas.When the concentration of Clorine gas is higher than the threshold value,audible and visual warning signals are automatically generated.The working principle,circuit design,method of software design and results of experiments of this device are introduced.Due to temperature compensation and digital signal processing,the measuring accuracy of the device is improved,and the error is less than 2 %.
