Description
Technical Field
The invention relates to a beacon device which is internally provided with an environmental state monitoring sensor and can rapidly configure deployment position information by using a voice mode, and an application system which realizes indoor or specific area range, peripheral environmental state monitoring of the deployment position of the beacon device and personnel positioning by using the device.
Background
Indoor and outdoor integrated positioning is a core application scene of the Internet of things, and according to prediction of relevant mechanisms, 70% of future Internet of things data have position information. The white paper for development of 2021 Chinese satellite navigation and location service industry, published by the China satellite navigation and positioning Association in 2021, 5 and 18 days, shows that the total output value of the China satellite navigation and location service industry in 2020 reaches 4033 million yuan national currency. In addition, white paper indicates that along with the rapid development of mobile location services and smart city construction, the requirement of high-precision indoor and outdoor seamless location services is increasingly urgent, and the related research and development and industrial work in the industry are obviously accelerated. In the future, with the deep development and application of the internet of things, cloud computing, artificial intelligence and the like, the research and development and application service popularization of the multisource fusion indoor and outdoor seamless positioning technology combined with the application of the Beidou become more and more investment hotspots of industrial fusion innovation.
Another wide application scenario of the internet of things is to construct a sensor network to continuously and uninterruptedly monitor various physical facilities and space environments, and ensure the safety of facility operation and the timeliness of responding to environmental changes. The communication technology of the Internet of things has the characteristics of low cost, low power consumption, easy coverage and narrow bandwidth, and is very suitable for the communication requirements of the sensor nodes with low real-time performance, small data volume and low power consumption. However, at present, many sensor nodes can only report monitoring data, but do not have spatial location information of the sensors. The satellite positioning system can be combined with the sensor in an outdoor environment, so that the monitored data has definite spatial position pointing, and the analysis and business decision of the data are facilitated. However, in an indoor environment, in order to obtain the position of a monitoring point, the deployment position of a sensor node must be determined in advance according to an indoor space structure, and then the information of the deployment position is fixedly written into node equipment in a wired or wireless manner or is uniformly recorded in a background system after deployment is completed, so that the process is complex.
In addition, as for indoor personnel positioning, an indoor positioning scheme widely applied in various industrial scenes is realized based on a low-power-consumption bluetooth technology, and the typical flow is as follows:
1) acquiring a space structure diagram of an indoor site environment in advance;
2) according to the space structure diagram, installing and deploying low-power-consumption Bluetooth beacon equipment at a proper position, and recording the installation position of the beacon equipment in a background of a positioning system;
3) the method comprises the steps that a low-power-consumption Bluetooth beacon device broadcasts and sends a wireless signal containing inherent identification information of the device;
4) the positioning target is provided with or carries a low-power consumption Bluetooth receiving device;
5) the positioning target moves in an indoor area range covered by the wireless signal of the low-power-consumption Bluetooth beacon device;
6) the low-power-consumption Bluetooth receiving device receives a wireless signal sent by the low-power-consumption Bluetooth beacon equipment, and detects the signal intensity and the inherent identification information of the equipment;
7) the low-power consumption Bluetooth receiving device transmits the signal intensity and the inherent identification information of the equipment to a background end of a positioning system through a network communication system;
8) and the background of the positioning system determines the current position of the positioning target according to the signal intensity, the inherent identification information of the equipment and the low-power-consumption Bluetooth beacon equipment installation position recorded in advance by the background.
In the above scheme, the bluetooth low energy beacon device, as an important infrastructure for indoor positioning, needs to confirm the installation and deployment position in advance according to an indoor space structure and record the installation and deployment position in the background, so that the association binding between the beacon device and the space position is realized in the positioning system.
However, in the field of emergency management, such as indoor fire rescue and anti-terrorist assault rescue scenes, the command and dispatch terminal may need to monitor the environmental states of different indoor location points and the location information of personnel entering the indoor site in real time. However, in such scenarios, due to unpredictability of event occurrence time, location, and real-time field environment, and urgency of event handling requirements, conventional positioning beacon and sensor node deployment methods cannot meet the requirements. For such a scenario, a core problem to be solved is how to quickly configure the beacon device, i.e., the location information to be placed, into the beacon device having the sensor function by a field worker, so that the information sent by the beacon device to the outside includes not only the sensor monitoring data, but also the location information of the beacon placement, and the monitoring data has a definite location direction. Meanwhile, the receiving device carried by field personnel can transmit the received beacon position information, sensor monitoring data and beacon transmitting signal strength to the background command system, so that the background can monitor the positions and the field states of the field personnel in real time, the dispatching command efficiency is improved, and the personnel safety is guaranteed.
