The utility model public illumination MANET remote controllers, principle is as follows:
Intelligent Node Controller is connected to street lamp, obtains street lamp information, described street lamp information comprises the street lamp brightness that street lamp state and light intensity Acquisition Circuit collect, and a plurality of Intelligent Node Controller interconnects by power line; Intelligence Centralized Controller is connected to described Intelligent Node Controller, and this Intelligent Node Controller becomes forward node, and sends and collect street lamp information command to other Intelligent Node Controllers; Each Intelligent Node Controller is opened light intensity Acquisition Circuit, start to gather street lamp data, if being lamp, street lamp dodges state or the state that entirely goes out, Intelligent Node Controller is controlled drive circuit disconnection zero-cross triggering circuit, by street lamp power-off, and records street lamp information, close light intensity Acquisition Circuit, street lamp information is sent to forward node, otherwise records street lamp information, and be sent to forward node; Meanwhile, the concentrated microcontroller in intelligent Centralized Controller is connected to server by GPRS module.Forward node is sent to intelligent Centralized Controller by all street lamp information, if intelligent Centralized Controller successfully receives, empties the street lamp information in forward node; Otherwise, preserve the street lamp information in forward node; Intelligence Centralized Controller is sent to server by all street lamp information.Server receives all street lamp information, and street lamp information is saved to database, according to street lamp information, send street lamp control information to described intelligent Centralized Controller afterwards, intelligence Centralized Controller is sent to forward node by the control information of reception, forward node is sending to control information each Intelligent Node Controller, Intelligent Node Controller detects whether control information is the control information of this node, if, receive this control information, and control street lamp according to control information, otherwise do not receive this control information; Intelligent Centralized Controller is extracted, and this forward node becomes invalid node.
On the utility model hardware configuration, be divided into Intelligent Node Controller, power line, intelligent Centralized Controller and server.Its topological structure is star-like and bus type structure, is bus type structure, and between terminal node and controller, is hub-and-spoke configuration between terminal node and terminal node, and one of them terminal node is an Intelligent Node Controller and is connected to a street lamp.
Between terminal node and terminal node, by power line, transmitting control information and node device information, can be direct or indirect between intelligence Centralized Controller and any one terminal node communicate by letter, terminal equipment information and server controls order are exchanged and passed on, and control command information exchange is crossed directly connected terminal node and is forwarded and received and carry out by corresponding node.Node device information is sent to server data administrative center by intelligent Centralized Controller information processing packing by GPRS network, and control data corporation is processed information extraction by message data and deposited database in and be presented to keeper and control the page.
Intelligence Centralized Controller is connected to by interface on the interface of any terminal node, by microprocessor controls GPRS module, starts communication work.It carries out flow process for being first connected with server, and request msg Connection Service with transmission querying command, is finally obtained terminal node information and also arranged and send to server data administrative center to process after then connecting.
PLC power carrier module in Intelligent Node Controller is responsible for communicating by letter between terminal node and other-end node, wherein in Intelligent Node Controller, contain interface SCL and interface SDA, they are interfaces of terminal node and intelligent Centralized Controller, when intelligent Centralized Controller is received on terminal node, this terminal node is just automatically changeb to the effect that transponder role is responsible for controller reception and forwarding messages.
Between terminal node and terminal node, by power line, be connected in mutually in 220V electric power environmental and communicated, each node can receive the information of sending of any node in net group, and the information that each node sends can be received by all nodes in net group.PLC power carrier module utilizes BPSK modulation system to modulate the signal in 220V electric power wave, on power line, on any same power line, signal can be received and demodulate to the terminal node equipment in certain distance, then data flow given terminal node device processed to process.
In intelligent Centralized Controller circuit, what GPRS module adopted is single power supply, its supply district is 3.2V～4.8V, recommendation voltage is 4V, because can cause voltage to fall when module is carried out radio-frequency transmissions, more than the highest meeting of its current peak reaches 2A, therefore Power supply ability at least will reach 2A, due to for the supply voltage of controller chip be 5V, therefore adopt LDO low pressure difference linear voltage regulator, microcontroller and GPRS module for power supply are incorporated into a power supply to be provided, owing to being operated in the equipment on power line thereby the 220V selecting that gathers materials on the spot turns 5V2A Switching Power Supply.
Intelligence Centralized Controller can be connected with any terminal node realizes networking control.Therefore be need not be again for terminal node designs a set of power source design, according to simple calculating: GPRS module maximum power requirement P1max=V1maxI1max=4.8V*2A=9.6W.The remaining 0.4W of Switching Power Supply can provide two only to need the ATmega8L low-power chip of 3.6mA normally to work completely so.And in fact circuit actual power is far smaller than this value, therefore only on terminal node, fill power module, intelligent Centralized Controller is by the power interface power taking on terminal node.Through test maximum voltage of microcontroller power supply when GPRS module is carried out radio-frequency transmissions, drop into 4.75V, and the detection of power loss of microcontroller is 2.7V, therefore can not impact microcontroller at work.
Because the GPRS module pin level of intelligent Centralized Controller is 3V and the pin level of the microcontroller of being powered by 5V is 5V, cannot proper communication.Therefore need level shifting circuit as communication bridge.Simple process erects level shifting circuit with two triodes and carries out level match.
Select bidirectional thyristor to use as electronic switch, the relatively generation of electronics spark during relay switch, thyristor there will not be problems, for accurate and electromagnetic interference, requires on harsh equipment, to have very large adaptability.With respect to the mechanical switch of common relay, electronic switch has long service life, the fireballing advantage of switching over.Then with optocoupler thyristor, as bidirectional thyristor drive circuit, well adapt to the characteristic of the switching angle of thyristor, played again the effect of civil power and working power isolation.

Conversion logic 0: when TXD data low level, the be two ends of triode Q1 are without forward conduction voltage, not conducting of PN junction, the c of triode Q1 high level very now, through R4, the b utmost point of triode Q2 is also high level, therefore the PN junction conducting between the be of triode Q2, ce is conducting also, and the pin that now RXD holds is equal to ground connection so level is 0, and receiving terminal is received logical zero.
In like manner, the conversion logic in Fig. 3 too.
