This high power consumption communications of 4G can not meet requirement.And LORA wireless technologys can abandon prior art with reference to advantage and lack
Point, can accomplish long range and low power consumption transmission, therefore LORA wireless technologys are just arisen at the historic moment.
LoRa is the low-power consumption networking technology researched and developed by SemTech, using direct sequence spread spectrum technology, is shared using the whole world
ISM public frequencys 137-1020MHZ carries out wireless data transmission.Because it uses Sub-GHZ frequency ranges, relatively low work(is made it easier for
Telecommunication is consumed, and with stronger technical ability through walls.Low-power consumption is also substantially improved the service life of battery.Based on these
Advantage so that LoRa technologies obtain large-scale development application in Internet of Things.
And safety is too busy to get away topic forever, safety is weightier than Mount Tai, either relatives, friend, and still working together, who is in
Everybody can be on tenterhooks under mine.Traditional communication or network does not cover the limitation of position due to base station signal, causes
In the case that disconnected or signal is not strong in a network, it is impossible to the information of Real-time Feedback ore deposit subsurface environment.Break through the limit of network environment
System, the security situation grasped whenever and wherever possible under mine is particularly important.Active feedback Minepit environment information, it is to avoid unnecessary
Natural and man-made calamities are current in the urgent need to the major issue for considering to solve.
The content of the invention
The technical problem to be solved in the present invention overcomes existing defect, and there is provided a kind of Minepit environment peace based on LoRa technologies
Full detection method, it is remote with the strong advantage of ability through walls, disengaging Conventional communication mode and due to base using LORA wireless transmission distances
Signal of standing does not cover the limitation of position, and Minepit environment information, the problem of effectively can solving in background technology can be learnt in real time.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme:
The present invention provides a kind of Minepit environment safety detection method based on LoRa technologies, comprises the following steps:
(1)Monitoring portion point, monitoring portion subpackage wireless communication module containing LORA, microcontroller, sensor are set under mine
And power supply, microcontroller allows sensor to sample respectively data below according to interval set in advance:Temperature/humidity/oxygen content;
(2)The temperature/humidity of sampling/oxygen content data, respectively through screening and filtering, obtains effective data;
(3)The microcontroller is sent valid data by LORA wireless communication modules;
(4)The LORA wireless communication modules of total you receive the wireless signal for being loaded with temperature/humidity/oxygen content data;
(5)The signal that the microcontroller of total you is received to LORA wireless communication modules is handled, and does data processing ratio
It is right;
(6)If the data fit normal person of temperature/humidity/oxygen-containing quantity sensor can breathe or movable scope, described
Microcontroller allows the indicator lamp greening for representing temperature/humidity/oxygen-containing quantity sensor;Otherwise, microcontroller, which allows, represents temperature/wet
The indicator lamp of degree/oxygen-containing quantity sensor reddens, while controlling alarm jingle bell.
(7)The ambient parameter after processing is sent to every work by total you microcontroller by GPRS/3G/4G networks in addition
Make personnel, helping, they understand working environment in time, prevent disaster.
The beneficial effect that is reached of the present invention is:
1. LORA is low in energy consumption, can work long hours in adverse circumstances, and transmission range is farther out, and has stronger energy through walls
Power;
2. the present invention realizes LORA wireless telecommunications and the combination of GPRS/3G/4G communication networks;
3. the present invention can predict mine safety information in advance, at the same can security exception under monitoring mine in real time, can shift to an earlier date
Avoid natural and man-made calamities.
