Description

Technical Field

[0001] This utility model belongs to the field of intelligent control technology, specifically relating to an emergency supplies activation system. Background Technology

[0002] Emergency supplies refer to the essential material support required throughout the entire emergency response process for sudden public events such as severe natural disasters, accidents, public health emergencies, and social security incidents. Emergency supply warehouses are locations where emergency supplies are categorized, organized, and inventoried to maximize their effectiveness in disaster prevention and mitigation efforts.

[0003] Existing emergency supplies calling systems include microphone sensors, relays, and audible and visual alarms. Microphone sensors are activated by a wake-up word, and the audible and visual alarms are placed at the corresponding emergency supplies locations. However, existing emergency supplies calling systems have the following drawbacks:

[0004] 1. Inconvenient post-maintenance: After the program is burned, the wake-up word, relay sequence, sound and light alarm, and emergency supplies placement are all one-to-one and cannot be easily modified. If the emergency supplies are moved later, the sound and light alarm will not respond to the corresponding emergency supplies when the wake-up is activated. If the relays malfunction during use, the corresponding sound and light alarm will not respond when the wake-up is activated.

[0005] 2. Poor wake-up effect: The existing emergency material call system mainly relies on microphone reception. If the external noise is too loud or the environment is complex, it will affect the wake-up effect and cause the system to fail to respond.

[0006] Therefore, developing a new type of emergency supplies activation system has great market potential. Utility Model Content
