AI Technical Summary

Problems solved by technology

[0004] At present, a large number of home security and environmental monitoring and alarm devices based on wireless sensor networks using the above-mentioned Cloudlink technology have appeared on the market, but in practical applications, the inventors have found that the above-mentioned technical solution has the following disadvantages. The normal use of the intelligent control unit, network transmission unit, and alarm information processing unit cannot be guaranteed when the power supply is cut off or the power supply is interrupted

Second, there is no arming and disarming function, and it is easy to cause false alarms to affect normal use

Third, there is no emergency button, and the alarm cannot be called in the disarmed state

Fourth, there is no alarm monitoring for the most important air and water
