Intelligent alarm system and method

Abstract

The invention provides an intelligent alarm system and method. The system comprises: a sensor module which includes multiple types of sensors and multiple wireless data emission modules respectively connected with the sensors; a data processing module which receives data information emitted by the wireless data emission modules and, when the data information is alarm information, sends corresponding control instructions to an alarm module according to the alarm information, wherein the control instructions comprise indication signs ID and one or more from single-frequency signals, pulse signals and frequency sweep signals; and the alarm module which is connected with the data processing module through a wireless mode, receives the control instructions of the data processing module and emits different alarm sound according to the different control instructions, wherein the control instructions comprise emitting long sound in case of the single-frequency signals, the control instructions comprise emitting interruption sound in case of the pulse signals and the control instructions comprise emitting variable frequency sound in case of the frequency sweep signals. According to the invention, wiring is unnecessary, disposition is simple, the expandability is good, and the alarm information can be identified through the alarm sound.

Description

technical field [0001] The invention relates to the field of alarm device design, and more specifically, to an intelligent alarm system and method. Background technique [0002] With the development of society, the scope of family security is becoming wider and wider. Anti-theft, fire prevention, and natural gas leakage prevention are all within the scope of monitoring. Everyone goes to work during the day and no one is guarding at home. Once a fire occurs, it will be very delayed to find and deal with it. The loss is great, and so is the theft, which can only be known after a long time has passed. Similar problems exist in warehouses and construction sites. For example, when there is no one in the warehouse or construction site at night, timely detection of dangers such as fire and theft and timely alarming can minimize losses. [0003] At present, the traditional intelligent alarm system is established in a wired way, and the communication lines are pre-arranged to the pl...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional intelligent alarm system is established in a wired way, and the communication lines are pre-arranged to the planned points, and the communication network is established according to the corresponding networking rules. This establishment method has troublesome wiring, complicated deployment, and poor scalability. It is not conducive to system network reconstruction and other shortcomings, and the buzzer in the intelligent alarm system has only one alarm sound, and the type of alarm information cannot be judged from the sound. For example, it is impossible to distinguish whether it is a natural gas leak or theft from the alarm sound.
