Description
Technical field
The invention belongs to internet of things field more particularly to a kind of tourist group's intelligent management systems based on LoRa.
Background technique
As the improvement of people's living standards, the number traveled every year increases year by year, this also gives the management of tourism to bring
More challenges.During tourism, often occur et al. or have the case where personnel fall behind, affect the trip of whole team
It arranges.So how team's number more than one, guarantee that tourist's is safe and orderly also more difficult, this is also each tour guide and travel agency
Problem.
Summary of the invention
Against the above technical problems, the invention discloses a kind of tourist group's intelligent management system based on LoRa, realizes
Partial automation manages tourist, alleviates the difficulty of management of tour guide tourist group, saves human cost.
In this regard, the technical solution adopted by the present invention are as follows:
A kind of tourist group's intelligent management system based on LoRa comprising LoRa Cloud Server, LoRa tour guide's gateway and LoRa trip
Objective node；
The LoRa tour guide gateway includes central processing unit, LoRa communication module, power supply module and network module, and the LoRa is logical

LoRa tourist's node is conducted a sightseeing tour gateway communication by LoRa network and LoRa, LoRa tour guide's gateway by network module with
LoRa Cloud Server is communicated.
Wherein, LoRa Cloud Server preferably passes through 3G, 4G with LoRa tour guide's gateway or IP network communicates, LoRa tour guide's gateway
It is communicated between LoRa tourist's node by LoRa.LoRa Cloud Server major function is the history number for storing LoRa tour guide's gateway
According to.LoRa tour guide's gateway is used to tour guide.LoRa tour guide's gateway further includes the photographing module for taking tourist's head portrait, is pressed
Key module is used to be manually operated the key of gateway, and display module carries out status display.
LoRa tourist's node is used to tourist.The power supply of LoRa tourist's node is opened, LoRa tourist's node can be first
Transmission networks application packet to LoRa tour guide's gateway, and LoRa tour guide's gateway can reply LoRa tourist's node and network successfully, LoRa tourist
Node enters working condition, and at this moment, LoRa tourist's node can constantly receive the positioning packet that LoRa tour guide's gateway sends over, then
By RSSI intensity, oneself is determined with LoRa at a distance from tour guide's gateway, while LoRa tourist's node can also receive other LoRa trip
The positioning packet that objective node sends over determines that oneself is according to the number for the positioning packet that can receive other LoRa tourist's nodes
It is no to fall list.If with farther out, LoRa tourist's node can prompt tourist at a distance from LoRa tour guide's gateway, if falling list, LoRa tourist's section
Point also will do it same prompt.
Further, the network module includes ethernet module, GSM/GPRS module, 3G/4G/5G module or WIFI mould
At least one of block.
Further, the central processing unit, control module be 8 MCU, 16 MCU, 32 MCU, DSP, FPGA or

As a further improvement of the present invention, the LoRa tour guide gateway includes camera.
As a further improvement of the present invention, tourist group's intelligent management system based on LoRa using following steps into
Row management:
Step S101, LoRa tourist's node initializing, and periodically send heartbeat packet, LoRa tour guide's gateway is according to the pipe of setting
Range is managed, transmission power, LoRa tour guide's gateway periodic broadcasting positioning packet are initialized；
Step S102, LoRa tourist's node receive positioning packet, obtain RSSI(Received Signal Strength
Indication, the instruction of received signal intensity)；It may determine that LoRa tourist's node and LoRa tour guide's gateway by the RSSI value
Distance；
Step S103, LoRa tourist's node judge RSSI value, if RSSI value is less than setting critical value, LoRa tourist's node is wide
Broadcast positioning packet；If LoRa tourist's node receives reply, repeatedly step S102；If do not received, control module is opened
The alarm module of LoRa tourist's node, LoRa tourist's node send warning message and give LoRa tour guide's gateway, and tourist obtains LoRa trip
After the prompting of objective node, alarm module is closed by key module.
As a further improvement of the present invention, the LoRa tour guide gateway is carried out data transmission using following steps:
Open the power supply of LoRa tour guide's gateway, LoRa gateway of conducting a sightseeing tour connects LoRa Cloud Server, if successful connection, into online
Its communication data between LoRa tourist's node is sent to LoRa Cloud Server by operating mode, LoRa tour guide's gateway in real time；
If connection is unsuccessful, enter independent working mode, by the communication data between LoRa tour guide's gateway and LoRa tourist's node
It is stored in LoRa tour guide's gateway.
As a further improvement of the present invention, the use following steps of LoRa tourist's node work:
The power supply of LoRa tourist's node is opened, LoRa tourist's node networks to LoRa tour guide's gateway application, if networked successfully,
LoRa tourist's node receives the positioning packet of LoRa tour guide gateway and other LoRa tourist's nodes, obtains the positioning of LoRa tour guide's gateway
The RSSI of packet starts alarm module if RSSI value is less than setting critical value；If it is critical that RSSI value is greater than or equal to setting
Value then counts the number that can get other LoRa tourist's nodes of positioning packet, if number is less than setting number, starts report
Otherwise alert module sends positioning packet to other LoRa tourist's nodes.Here setting number is preferably 3.
The present invention uses the scheme of LoRa wireless communication technique, using the low-power consumption of LoRa, long range and low price feature,
Can one controlled range based on LoRa of construction at lower cost tourist group's intelligent management system.
Compared with prior art, the invention has the benefit that
First, using technical solution of the present invention, the difficulty of management of tour guide tourist group is alleviated, human cost is saved, realizes
Partial automation manages tourist；It facilitates tourist to play, what can be trusted plays, has and fall single danger and tourism and terminate all
There is prompting.
Second, it is adjustable to the range of tourist group's management using technical solution of the present invention, it can be according to the big of tourism place
It is small and adjust the range that manages automatically；The communication distance of LoRa is another to send power, communication distance by adjusting up to 20 kilometers
The most short distance that can control within 10 meters, thus essentially all of tourist group can be covered and gone on a tour scope management demand,
And power consumption and cost can accomplish it is relatively low.In addition, LoRa tourist's node can accomplish it is very small, can be made bracelet or
