Abstract

A substation smoke alarm system relates to the field of medical apparatuses. The system comprises a smoke alarm device and an intelligent mobile terminal. The smoke alarm device comprises a smoke sensor, a smoke controller, a smoke restorer, a voice alarm, and a light alarm. By setting the smoke restorer and the intelligent mobile terminal, the working condition of the smoke alarm device can be monitored remotely. When the alarm is raised, the smoke restorer sends a smoke signal to the intelligent mobile terminal, and an operator receives the smoke signal through the intelligent mobile terminal and judges whether the alarm is real. If the alarm is false, the intelligent mobile terminal can be operated to make the smoke restorer reset the powered-off external power supply of the smoke alarm device. Thus, there is no need to transfer maintenance personnel to the site for troubleshooting and power-off resetting when there is false alarm. The substation smoke alarm system is used for substation fire detection.
