Abstract
Description
Technical Field
[0001] The present invention relates to the field of fire alarm technology, and in particular to a fire alarm system for new energy vehicles in an underground garage based on NB-iot technology. Background Art
[0002] New energy vehicles catch fire mainly due to thermal runaway of the battery. The proportion of fires during charging or static state exceeds 50%, which is difficult to prevent. In addition, there may be no one at the side of the new energy vehicle when the fire occurs, and the golden time for firefighting is often missed. When new energy vehicles catch fire in underground garages, the situation is even worse. There are fewer pedestrians in the underground garage, and the possibility of timely discovery is lower. In addition, fire trucks cannot enter the underground garage, and firefighters cannot effectively put out the fire. The burning new energy vehicles may ignite the cars around the parking spaces, causing greater losses and even threatening people's lives. NB-iot technology has wide coverage, stronger signal penetration, and low power consumption, and is more suitable for buildings such as underground garages. In order to prevent greater losses caused by the failure to effectively extinguish the fire in a new energy vehicle in the underground garage, the present invention can effectively avoid it.

The Internet of Things communication module 11 uses the BC26NB-iot communication module, which can transmit the detected data to the cloud platform 12.
[0019] The smoke sensor 1 uses the MQ-2 smoke alarm to collect the smoke status around the new energy vehicle in real time.
[0020] The digital temperature sensor 2 is a DS18B20 temperature sensor, which is used to collect temperature information of new energy vehicles in real time.
[0021] The Internet of Things communication module 11 uses a BC26NB-iot communication module, which can transmit the detected data to the cloud platform.
[0022] The main control chip 6 is also electrically connected to the positioning module 3 for detecting the position of the new energy vehicle 14 in the underground garage when a fire occurs.
