Value.
During present invention work, the intelligent monitoring of photovoltaic plant is specifically realized according to the following steps：
Step 1：Photovoltaic plant scene illumination and power output data are responsible for collection by the node of terminal 1, and terminal 1 is each other
It is not directly connected.Due to illumination and power output will not suddenly change, so the time segment of terminal 1 collection Lighting information and output
Power information, i.e., gathered an illumination every one minute, then gathered power output data every one minute, was followed with 2 minutes for the cycle
Ring is gathered.Route 2 is sent at once after adding mark 1,2 respectively in the illumination collected and the valid data of power output
Node or telegon 3.2 node arrangements are route to be passed by the node of terminal 1 in the centre of regular hexagon, illumination and power output data
It is sent between 2 nodes of route, 2 nodes of route and is connected to telegon 3 by shortest path principle, is responsible in the range of this regular hexagon
The illumination that collects of terminal 1 and output power information or 2 illumination sent and power output number are route by next stage
According to being sent to telegon 3；Telegon 3 is responsible for building network and is responsible for setting up whole network and extraneous communication, is installed in
It is joined directly together on controller 4 and with 2 nodes of route or the node of terminal 1, receives its data transmitted.If terminal 1 is saved
Point is joined directly together with telegon 3, then directly transmits illumination, output power information to telegon 3；If the node of terminal 1 not with association
Device 3 is adjusted to be connected, then by 2 node-routings of one or more routes to telegon 3, such networking effectively reduces information transmission
When number of hops, it is to avoid the loss of information.
Step 2：ZigBee-network 31 is sent the illumination being collected into and power output data by telegon 3, by ZigBee/
The ZigBee module 6 of TD-LTE gateways 5 is responsible for reception.Illumination and output power information are from the top of ZigBee module 6
ZigBee application layers 54 start removal ZigBee application layer packet heads and obtain 53 data frame of ZigBee-network layer, remove ZigBee nets
Network layers packets headers obtain the data frame of ZigBee MAC layers 52, and ZigBeeMAC layers of packets headers of removal obtain ZigBee physical layers 51 and counted
The data to be transmitted of ZigBee wireless networks 31 are obtained according to frame, removal ZigBee physical layer packet heads；Then, ZigBee physical layers
Last data frame is transmitted to transition zone 50 by 51 by serial ports, and transition zone 50 is decomposed and recombinated to the data obtained, obtains new
Valid data.Then this data is sent to TD-LTE modules 8 by serial ports.After the data comprising full detail are obtained,
TD-LTE modules 8 are encapsulated again to data, and process is as follows：
1st, addition TD-LTE module physicals layer packets headers, obtain the data frame of TD-LTE module datas link layer 56.
2nd, TD-LTE module data link layer packet heads are added, the data frame of TD-LTE module grids network layers 57 is obtained.
3rd, TD-LTE module grid network layers packets headers are added, the data frame that can be transmitted with 4G networks 9 again is obtained.
4th, the incoming 4G networks 9 of information that finally will be disassembled and encapsulate by ZigBee/TD-LTE gateways 5.The processing of gateway
The process of data processing is separated, is conducive to data processing to obtain order and reliability, while TD-LTE technologies possess high data
Transfer rate, does not result in jam of the data in gateway.
Step 3：The illumination of incoming 4G networks 9 and output power information are transmitted to mobile terminal 13 for movement respectively as needed
End is checked and feeds back and be transmitted to management storage end 12 and handled, and recognizes and stores.At present because 4G networks 9 are to be directed to mobile phone
Network, and it is mostly industrial computer to manage storage end 12, just may be used so only needing to install 4G adapters in management storage end
Using 4G networks 9, it so can not only possess the advantage of Data Over Cable, and the wiring of complexity can be avoided.
Step 4：It is bent that management storage end 12 has P-V of the different illumination gone out according to local former years lighting drawing with a temperature of
Line, i.e. power output and voltage curve.The illumination and power output data that 12 pairs of storage end of management is passed back by 4G networks 9 have
Contents extraction is imitated, is distinguished according to 1 or 2 classes of mark after illumination and output power information, the data and curves pair stored with storage end
If the error of power output and set-point under the certain illumination arrived than on-site collections is less than an error definite value, by light
Stored according to output power information to the memory block of management storage end 12.If analysis finds the voltage of input under this illumination,
When power output deviates maximum power point, management storage end 12 according to the control algolithm used, by 4G networks 9 to
The TD-LTE modules 8 of ZigBee/TD-LTE gateways 5, which are sent, contains how to adjust input in input voltage adjust instruction, instruction
The position of the information of voltage and some photovoltaic cells of required regulation（By taking conductance increment method as an example, when management storage end 12
Cell output under certain intensity of illumination received is less than the experience peak power under the intensity of illumination, then judges now live
P-V curve derivatives, if derivative is more than 0, send the instruction of increase input voltage, if reciprocal be less than 0, send reduction
The instruction of input voltage）.
TD-LTE modules 8 are received after the input voltage adjust instruction from 4G networks 10, divest TD-LTE Internets point
Group head, which obtains the data frame of TD-LTE data link layers 56, divest TD-LTE data link layer packets head obtains TD-LTE physical layers
55 data frames, divest the data frame that TD-LTE physical layer packets head obtains only including payload.TD-LTE physical layers 55 will most
Whole data send transition zone 50 to by serial ports, and transition zone 50 is rearranged and changed to data to be sent by data between serial ports biography
To ZigBee module 6, the data that 6 pairs of ZigBee module is transmitted carry out handling as follows：
1st, addition ZigBee physical layer packets head obtains the data frame of ZigBee physical layers 51；
2nd, addition ZigBee MAC layer packets headers obtain the data frame of ZigBee MAC layers 52；
3rd, addition ZigBee network layer packets head obtains the data frame of ZigBee Internets 53；
4th, addition ZigBee application layer packets head obtains the data frame of ZigBee Internets 53；
Then ZigBee module 6 will encapsulate the information transmission completed to telegon 3, and telegon 3 communicates information to control again
Device 4 processed, controller 4 finds the position for the photovoltaic cell for needing to adjust according to command content, and input voltage is adjusted further according to content,
Solve live abnormal conditions.Due to 4G networks 9 and the real-time of TD-LTE technologies, the system realizes the long-range real-time of controller
Operation.
Step 5：Afterwards, management storage end 12 continues to monitor the data passed back by ZigBee/TD-LTE gateways 5, if passed
The illumination returned meets the P-V curves that management storage end 12 is stored with power output, then stores normal value；If still deviateing normal
Value, then continue step 4 until normal.
Step 6：When the live illumination of observation photovoltaic at any time and temperature parameter are wanted in mobile terminal 13, or to live illumination or temperature
When degree parameter is changed, it is only necessary to send instructions to ZigBee/TD-LTE gateways 5, the processing of instruction and biography by 4G networks 9
Defeated process such as step 4.
