Problems solved by technology

The alarm mode of the prior art NB-IoT system is limited to individual or stand-alone notifications, and the alarm mode of the prior art NB-IoT system does not There is no way to ensure that everyone in the vicinity of the fire is informed of the fire
In addition, in order to reduce power consumption, existing NB-IoT systems often operate in power saving mode (PSM) or enhanced discontinuous reception (eDRX) mode, and sensors that detect smoke may not be able to issue an alarm in time

Embodiment Construction

[0021] figure 1 It is a functional block diagram of an event alarm 100 in the embodiment of the present invention. The event alarm system 100 includes a mesh network (MESH) communication unit 10, a NB-IoT communication unit 20, a microcontroller (MCU) 30, a sensor 40, a notification unit 50, an operation interface 60, and a power supply 70.

[0022] figure 2 It is a schematic diagram of an event alarm system 200 in an embodiment of the present invention. The event alert system 200 comprises a plurality of nodes N 1 ~N M , each node consists of figure 1 The event alarm 100 shown here can each measure data at the location and notify other nodes using the MESH architecture when a specific event is detected. Each node N 1 ~N M It can be used as a data sending node, a data receiving node, or a data relay node. In a first low power consumption node NL as a data sending node 1 and a second low power consumption node NL as a data receiving node 2 When the radio coverage ra...

Abstract

The invention discloses an event alarm and an event alarm system. The event alarm comprises a sensor, a notification unit, a mesh network communication unit, a narrow-band Internet of Things communication unit and a microcontroller. The narrow-band Internet of Things communication unit is used for uploading data measured by the sensor. The microcontroller is used for judging whether a specific event occurs or not according to the data measured by the sensor, and indicating the notification unit to send out an on-site warning, the narrow-band Internet of Things communication unit to send out afirst warning signal and the mesh network unit to send out a second warning signal when judging that the specific event occurs.

Description

technical field [0001] The invention provides an event alarm and an event alarm system, in particular to an event alarm and an event alarm system that support both MESH technology and NB-IoT technology. Background technique [0002] Narrow Band-Internet of Things (NB-IoT) is a low power wide area (LPWA) technology based on the 3rd Generation Partnership Project (3GPP) standard. That is to say, most of the existing base stations can be directly upgraded as the medium of data transmission. Applications of NB-IoT include smart metering (electricity, gas or tap water, etc.), intruder and fire alarms for homes and commercial properties, environmental monitoring, smart city infrastructure, wearable devices and medical devices, etc. [0003] Take the fire alarm as an example. Once smoke is detected, it will sound the siren and send a text message to a specific mobile phone number, dial a specific mobile phone number, or notify through a specific mobile phone application through NB...
