When the present invention works, specifically realize the intelligent monitoring of photovoltaic plant according to the following steps
:
Step 1: the on-the-spot illumination of photovoltaic plant and output power data are responsible for collection by terminal 1 node, and terminal 1 does not directly connect each other.Because illumination and output power can not change suddenly, so terminal 1 time segment gathers Lighting information and output power information, namely gathering an illumination every one minute, then gathered output power data every one minute, was loop cycle collection with 2 minutes.The illumination collected and output power valid data in add mark 1 respectively, send route 2 node or telegon 3 after 2 at once to.Route 2 node arrangement is in orthohexagonal centre, illumination and output power data are sent to route 2 node by terminal 1 node, be connected to telegon 3 by shortest path principle between route 2 node, be responsible for the illumination that the terminal 1 in this regular hexagon scope collected and output power information or the illumination sent by next stage route 2 and output power data and be sent to telegon 3; Telegon 3 is responsible for building network and is responsible for setting up whole network and extraneous communication, to be installed on controller 4 and to be directly connected with route 2 node or terminal 1 node, accepting the data that it transmits.If terminal 1 node is directly connected with telegon 3, then directly transmit illumination, output power information to telegon 3; If terminal 1 node is not connected with telegon 3, then through one or more route 2 node-routing to telegon 3, such networking effectively reduces number of hops during information transmission, avoids the loss of information.
The illumination of collecting and output power data are sent by telegon 3 by step 2:ZigBee network 31, are responsible for reception by the ZigBee module 6 of ZigBee/TD-LTE gateway 5.Illumination and output power information are removed ZigBee application layer packet head and are obtained ZigBee-network layer 53 Frame, remove ZigBee-network layer packets headers and obtain ZigBee MAC layer 52 Frame from the top ZigBee application layer 54 of ZigBee module 6, remove ZigBeeMAC layer packets headers and obtain ZigBee Physical layer 51 Frame, remove ZigBee physical layer packet head and obtain the data that ZigBee wireless network 31 will transmit; Subsequently, last Frame is passed to transition bed 50 by serial ports by ZigBee Physical layer 51, and transition bed 50 pairs of the data obtaineds decompose and recombinate, and obtain new valid data.Then these data are sent to TD-LTE module 8 by serial ports.After obtaining comprising the data of full detail, TD-LTE module 8 pairs of data encapsulate again, and process is as follows:
1, add TD-LTE module physical layer packets headers, obtain the Frame of TD-LTE module data link layer 56.
2, add TD-LTE module data link layer packet head, obtain the Frame of TD-LTE module grid network layers 57.
3, add TD-LTE module grid network layers packets headers, obtaining can the Frame that transmits of 4G network 9 again.
4, finally the information disassembled through ZigBee/TD-LTE gateway 5 and encapsulate is imported into 4G network 9.The process of gateway by the process of data processing separately, is conducive to data processing and obtains order and reliability, and TD-LTE technology has high data transmission rate simultaneously, and data can not be caused at the jam of gateway.
Step 3: import the illumination of 4G network 9 and output power information into and pass to mobile terminal 13 as required respectively and check for mobile terminal and feed back and pass to managed storage end 12 and process, identify and store.At present due to network that 4G network 9 is for mobile phone, and managed storage end 12 is mostly industrial computer, so only need to install 4G adapter at managed storage end just can use 4G network 9, so not only can have the advantage of Data Over Cable, and complicated wiring can be avoided.
Step 4: managed storage end 12 has according to the P-V curve at the different light that local former years, lighting drawing went out and temperature, i.e. output power and voltage curve.Managed storage end 12 carries out effective contents extraction to the illumination passed back by 4G network 9 and output power data, after distinguishing illumination and output power information according to mark 1 or 2 class, if hold the data and curves stored to contrast with storing. on-site collection to certain illumination under output power and the error of set-point be less than an error definite value, then illumination and output power information are stored into the memory block of managed storage end 12.Find that the voltage of input is under this illumination if analyzed, when output power departs from maximum power point, managed storage end 12 is according to adopted control algolithm, input voltage adjustment instruction is sent to the TD-LTE module 8 of ZigBee/TD-LTE gateway 5 by 4G network 9, the position of some photovoltaic cell of information and the required adjustment how adjusting input voltage is contained (for conductance increment method in instruction, when the cell output under certain intensity of illumination that managed storage end 12 accepts is lower than the experience peak power under this intensity of illumination, then judge now on-the-spot P-V curve derivative, if derivative is greater than 0, then send the instruction increasing input voltage, if inverse is less than 0, then send the instruction reducing input voltage).
After TD-LTE module 8 receives the input voltage adjustment instruction from 4G network 10, divest TD-LTE network layer packet head obtain TD-LTE data link layer 56 Frame, divest TD-LTE data link layer packets head and obtain TD-LTE Physical layer 55 Frame, divest the Frame that TD-LTE physical layer packet head only comprised useful load.TD-LTE Physical layer 55 sends final data to transition bed 50 by serial ports, and between transition bed 50 pairs of data rearrangements and conversion are passed by serial ports, data deliver to ZigBee module 6, and it is as follows that ZigBee module 6 carries out process to the data transmitted:
1, add ZigBee physical layer packet head and obtain ZigBee Physical layer 51 Frame;
2, add ZigBee MAC layer packets headers and obtain ZigBee MAC layer 52 Frame;
3, add ZigBee network layer packet head and obtain ZigBee network layer 53 Frame;
4, add ZigBee application layer packet head and obtain ZigBee network layer 53 Frame;
Then ZigBee module 6 sends the information encapsulated to telegon 3, telegon 3 sends information to controller 4 again, controller 4 finds the position of the photovoltaic cell needing adjustment according to command content, then according to Content adaptation input voltage, solves on-the-spot abnormal conditions.Due to the real-time of 4G network 9 and TD-LTE technology, this system achieves the long-range true-time operation of controller.
Step 5: afterwards, managed storage end 12 continues to monitor the data passed back by ZigBee/TD-LTE gateway 5, if the illumination passed back and output power meet the P-V curve that managed storage end 12 stores, is then stored by normal value; If still depart from normal value, then continue step 4 until normal.
Step 6: when mobile terminal 13 is wanted to observe photovoltaic scene light and temperature parameter at any time, or when on-the-spot illumination or temperature parameter are changed, only need to send instructions to ZigBee/TD-LTE gateway 5 by 4G network 9, the process of instruction and transmitting procedure are as step 4.
