Problems solved by technology

[0005] (1) Due to the short propagation distance of the Bluetooth signal (generally about 10 meters), the Bluetooth detection environment is limited, and the Bluetooth broadcast signal does not guarantee that the receiver can be successfully read, and Bluetooth may also need to establish a connection for communication. For a long time, the alarm delay increases
[0006] (2) Since Bluetooth devices need to perform signal broadcasting for a long time, as well as signal transmission and frequent signal transmission, the energy consumption of the entire system is very large, and resources are seriously wasted
[0007] Therefore, in order to solve the technical problems of alarm signal delay and high power consumption in the prior art, an energy-saving alarm method and alarm system are needed

Embodiment 1

[0052] like figure 1 Shown is a structural block diagram of a bluetooth beacon-based energy-saving warning system of the present invention. According to an embodiment of the present invention, a bluetooth beacon-based energy-saving warning system can be applied to scenarios such as home warning and warehouse warning. An energy-saving alarm system based on bluetooth beacons provided by the present invention includes a plurality of bluetooth sensors, bluetooth beacons and network managers distributed in different spatial positions. A plurality of bluetooth sensors are respectively connected to bluetooth beacons by bluetooth, and bluetooth beacons are connected to a network management system. A plurality of bluetooth sensors distributed in different spatial positions are used to collect data signals of the respective positions. For example, when applied to home alarms, the energy-saving alarm system based on Bluetooth beacons distributes multiple Bluetooth sensors at different s...

Embodiment 2

[0091] In the first embodiment, on the basis that the data signal collected by the Bluetooth sensor is out of the safe range, the broadcast period of the Bluetooth sensor is adaptively adjusted.

[0092] The difference between this embodiment and Embodiment 1 is that if the Bluetooth sensor detects a significant increase in the monitoring signal, the data signal collected by the Bluetooth sensor exceeds the safe range, such as the smoke concentration exceeds the safe range.

[0093] When the data collected by a certain Bluetooth sensor exceeds the safe range, the broadcast period of the Bluetooth sensor is at least halved, and at the same time, it is checked whether the average reception period of the Bluetooth sensor broadcast calculated by the Bluetooth beacon is halved.

[0094] For example, the data collected by the Bluetooth sensor m203 exceeds the safe range, and the broadcast cycle of the Bluetooth sensor m203 is at least halved. At the same time, check whether the avera...

Embodiment 3

[0098] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the data collected by the Bluetooth sensor reaches a preset dangerous value.

[0099] According to an embodiment of the present invention, when the data collected by a certain Bluetooth sensor reaches a preset dangerous value, the signal period of the collected data broadcasted by the Bluetooth sensor is shortened to a minimum value, and at the same time, the Bluetooth connection with the Bluetooth beacon is checked.

[0100] For example, when the Bluetooth sensor m203 detects that the data signal reaches a preset dangerous value, the Bluetooth sensor m203 shortens the broadcast period to a minimum value, such as 100ms. At the same time, the Bluetooth sensor m203 initiates a Bluetooth connection with the Bluetooth beacon to ensure that the broadcast signal can be confirmed to be transmitted to the Bluetooth beacon, and then reported to the network management for an alarm, and the alarm signa...

Abstract

The invention provides an energy-saving alarm method and alarm system based on a Bluetooth beacon. The method comprises the steps that whether a sampling result exceeds at least one preset early warning threshold value and at least one preset alarm threshold value or not is judged, and if yes, a Bluetooth sensor adjusts the sampling period and the broadcasting period of the Bluetooth sensor according to the preset early warning threshold value or the alarm threshold value; whether the average receiving period of the Bluetooth broadcast signals received by the Bluetooth beacon and adjusted by the Bluetooth sensor is not higher than or lower than at least two average receiving periods of the Bluetooth beacon is judged; and if the Bluetooth sensor still cannot ensure that the average receiving period of the Bluetooth broadcast signal of the Bluetooth sensor received by the Bluetooth beacon is not higher than or lower than at least two average receiving periods of the Bluetooth beacon through adaptive adjustment, the Bluetooth sensor initiates connection with the Bluetooth beacon to give an abnormal alarm. According to the technical scheme, the Bluetooth sensor and the Bluetooth beaconrealize broadcast in two directions, electric energy is saved, it is ensured that alarms can be sent out in time, and missed alarms are avoided.

Description

technical field [0001] The invention relates to the technical field of safety monitoring, in particular to a Bluetooth beacon-based energy-saving alarm method and an alarm system. Background technique [0002] Due to the low cost of Bluetooth, a large number of Bluetooth devices have been deployed in commercial environments, including some Internet of Things applications and sensor applications. Among them, smoke sensors, combustible gas sensors, etc. will also be used in safety alarm applications. These Bluetooth devices collect safety-related data, such as the concentration of dangerous gases, to determine whether there is a potential safety hazard, and issue an alarm in time. [0003] There are two ways to send out the alarm signal, one is to broadcast the signal through Bluetooth, and the other is to communicate through the Bluetooth connection to send the alarm signal to the outside world, so as to ensure that the alarm signal can be transmitted to the network in time,...
