Technical scheme is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, the present invention proposes a kind of wisdom streetlamp management system based on LoRa wireless communication techniques, this is
System includes Cloud Server, gateway, ordinary node and enhancement mode node.
The ordinary node include hlw8012 electric energy computation chips, relay, LoRa radio frequency chips, antenna and
Stc12c5a60s2 type microcontrollers.Ordinary node is installed on street lamp end, each ordinary node has a fixed ID, for tying up
Determine street lamp end.Ordinary node is responsible for sending the street lamp consumption information and the heartbeat packet of node that hlw8012 chips gather to gateway,
And can be controlled by relay road lamp switch relay, hlw8012 chips and LoRa radio frequency chips by serial ports with
Stc12c5a60s2 microcontrollers are connected.Relay switchs to 12V except being responsible for suppressing 220V, works normally node, is also responsible for
The switch of street lamp；Hlw8012 chips are responsible for gathering the energy consumption of street lamp；LoRa radio frequency chips and antenna are responsible for carrying out with gateway wireless
Communication；Stc12c5a60s2 microcontrollers utilize time-based distance measuring method and three side positioning modes, estimation ordinary node position.
The enhancement mode node adds SPECTR microwave detectors on the basis of ordinary node, and enhancement mode node includes
All functions of ordinary node, can also be by vehicle flowrate data transfer that SPECTR microwave remote sensors detect to gateway.One
A long section, an installation enhancement mode node is chosen in every 10 street lamps.Enhancement mode node quantity is installed far fewer than ordinary node
Spacious, have no occluder street lamp end is emptied in place, can so obtain preferable vehicle flowrate monitoring information.
The gateway includes GPRS on-line modules, brightness sensor, LoRa radio frequency chips, antenna and STM32 microcontrollers,
Brightness sensor, LoRa radio frequency chips, GPRS on-line modules are connected by serial ports with STM32 microcontrollers.Brightness sensor
For gathering brightness information, GPRS module is used to communicate with Cloud Server, and LoRa radio frequency chips are with antenna with leading to node
Letter.Brightness information that gateway is responsible for collecting and the nodal information received are sent to Cloud Server, and by the life of server
Order is sent to node.
The node and gateway information that the Cloud Server analysis collects, are responsible for issuing switch lamp order and light to node
Regulating command, and issue street lamp consumption information, information of vehicle flowrate, brightness information and street lamp fault to administrative staff and alert, pipe
Reason personnel can pass through web terminal or app ends remote management road lamp system.It is mutual by http protocol between Cloud Server and gateway
Pass data.
In the present invention, each gateway and node have fixed ID number, and ID number is unique, and gateway and node are equal
Using the LoRa communication technologys, the LoRa communication technologys have the characteristics that low frequency, arrowband, long range, low-power consumption.Gateway and node are formed
One Star Network, gateway are sent to node by way of broadcast and ordered, and each gateway can load thousands of in 5 to 10 kilometers
A node.
In the present invention, node sent heartbeat packet every 30 seconds to gateway, and Cloud Server passes through heartbeat packet combination hlw8012 cores
Piece collection street lamp energy consumption, judge street lamp whether failure.Server can inquire node, node if heartbeat packet is not received
Then judge street lamp fault without responding, also judge street lamp fault node every 30 seconds to gateway less than normal value if receiving street lamp energy consumption
Heartbeat packet is sent, the street lamp energy consumption that Cloud Server is gathered by heartbeat packet combination hlw8012 chips, judges whether street lamp is former
Barrier.Server can inquire node if heartbeat packet is not received, and node judges street lamp fault without response, if receiving street lamp energy consumption
Also judge street lamp fault less than normal value.Cloud Server analyzes brightness information and information of vehicle flowrate, is opened to street-lamp node issue
Light lamp order.
The server function module of the present invention is further described with reference to Fig. 2.
Server function module mainly has three：Management module, the data of module, web terminal and app ends with gateway communication
Library module.
Mainly the data that gateway sends over are judged with the module of gateway communication, are handled, with reference to brightness information
The quantity for needing to turn on light is calculated with information of vehicle flowrate.Under the conditions of the brightness for needing to turn on light, three etc. are set to vehicle flowrate
Level：During vehicle flowrate highest, street lamp standard-sized sheet；When vehicle flowrate is medium, street lamp interval switch, when vehicle flowrate is low, street lamp is opened every two
One.The module can also be directed to the nodes heart beat bag that sends over and consumption information, decision node whether failure.
Web ends and App ends management module be used for administrative staff show street-lamp node consumption information, switch lamp state,
Positional information and fault message are managed, the accurate control to single street-lamp node is realized by the management module.
Database module storage gateway and the brightness information of node collection, node location information, node ID number, node event
Hinder information, information of vehicle flowrate, and data progress additions and deletions are changed and look into operation.
The workflow of the present invention is further described with reference to Fig. 3.
Cloud Server constantly receives the information from gateway, comprising nodal information and gateway information, and thus judges street lamp
Node whether failure.If street-lamp node failure, Cloud Server sends fault warning to administrative staff, and alarm can pass through web terminal
Shown with app ends.If fault-free, Cloud Server judges whether to need switch lamp according to brightness information and nodal information, if
Switch lamp is needed, is just issued and ordered to node by gateway.
It is in conclusion of the invention by LoRa wireless communication techniques, singlechip technology, Microwave Measurement Technique, network service skill
Art, software technology and the fusion of Cloud Server technological perfectionism, so as to fulfill the informationization to street lamp, intelligent management, reach saving
Electric energy, the purpose overhauled in time.
The above, is only the embodiment in the present invention, but protection scope of the present invention is not limited thereto, and is appointed
What be familiar with the people of the technology disclosed herein technical scope in, it will be appreciated that the conversion or replacement expected, should all cover
Within the scope of the present invention, therefore, protection scope of the present invention should be subject to the protection domain of claims.
