二总线离子感烟火灾传感器

Two Bus Ion Sensing Smoke Sensor for Fire Alarm

介绍了一种新型的二总线离子感烟火灾传感器的设计原理和结构。该传感器由单源双电离室制成，应用范围宽，性能可靠，且具有预报警、报警、故障报警等功能，采用应答方式来传输电流信号。

In this paper, the design principle and structure of new kind of ion sensing smoke sensor is expounded with the two bus, the sensor is made of single radioactive source and two ionization chambers, with wide of uses and reliable properties, but the sensor can give a prewarning signal, fire signal and fault signal. The sensor signal is transmitted by the current with the way of reply.
