| 英文摘要: |
| The operation principle and key design points of every part of the circuit of photo-electric smoke-sensing fire detector are presented in detail. This circuit has the characteristic of usingmicroampere current to drive the milliampere device. And it has the anti-jamming circuit,so that thereliability of fire alarm is increased. Thus this paper has great value in theory and practice. |
