The still unlapped area of wired and wireless signal lays Internet of Things and provides a kind of technical scheme.
User side, collection terminal etc. are described below realizes program.
Edit the program of operation in user side, relay station, the microcontroller of collection terminal, edit in a computer and adopt
The program of collection data and video data, below we are briefly described these programs：
The program summary of user side microcontroller
The program of user side is roughly divided into two parts, the communication of the communication program, user side and computer of user side and relay station
Program, sketches separately below：1）Communication with regard to user side and relay station：A computer, a use is comprised in system schema
Family end, multiple relay station, each relay station have a collection terminal group, and a collection terminal group has multiple collection terminals, therefore user side
The communication actually with multiple relay stations for the communication with relay station, in order to be unlikely to multiple relay station transmitting conflicts, Wo Men
The numbering of relay station is set, being sequentially transmitted data for relay station provides foundation, due to each relay station and user side in program
Apart from different, some relay station distance users ends are closer, within the scope of user side can access；Some relay stations away from
Distant from user side, not within the scope of user side accesses, the signal user side of these relay stations does not receive.That
We just define a relay station is the relay station that user side accesses, and determines that its numbering is " No. 01 station ", therefore actual
What upper user side accessed is only the relay station at " No. 01 station ", and does not access other relay stations.Other relay stations are by connecing
The mode of power is sent to the relay station at " No. 01 station ", and " No. 01 station " relay station transfers data to user side again.Other relayings
Numbering of standing is " No. 02 station ", " No. 03 station ", " No. 04 station " etc..In user side program, if starting user side, and user
Have been sent from the instruction of gathered data, user side sends startup " No. 01 station " relay station first, and allowed " No. 01 station " to relay
The each collection terminal of collection terminal group stood sends data, and the data of the collection terminal that " No. 01 station " relay station is numbered with regard to this is sequentially transmitted meter
Calculation machine.After the completion of the transmission of this data, " No. 01 station " relay station can send, to user side, the instruction that data transmission completes.User
End receives after data transmission completes instruction, starts " No. 02 station " relay station（Notice that at this moment " No. 01 station " relay station is still in work
State）, then this instruction sends " No. 02 station " relay station to by " No. 01 station " relay station, and " No. 02 station " relay station starts,
And the collection terminal group of affiliated " No. 02 station " relay station can be sequentially transmitted data to " No. 02 station " relay station, " No. 02 station " relay station
Transfer data to " No. 01 station " relay station again, " No. 01 station " relay station receiving data sends computer to regard to data immediately.“02
The data instruction that completes of transmission equally can be sent, this instruction equally can be sent to use after the completion of the relay station data transmission of number station "
Family end, user side sends instruction again and starts " No. 03 station " relay station, by that analogy, until the collection terminal group belonging to all relay stations
Data all transmission completes, after the completion of the transmission of all data, user side can send the instruction closing all relay stations, all
Relay station quits work, in a dormant state；2）With regard to the communication of user side and computer, user side has received each relay station
After the data of transmission, transfer data to computer, then computer just can be stored calculating with logarithm according to processing one by one
In the data base of machine, in data transmission procedure, the data transfer display lamp in user side is flicker（This display lamp is permissible
It is set to digital display tube, with the numbering of the numbering of the relay station of digital form display transmission and collection terminal）, remind user data
Just in the transmission.When the data transfer display lamp in user side stops flicker, illustrate that the data of all collection terminals all passes
It is totally lost into, user side can send the data instruction that completes of transmission, computer also will no longer receiving data and storage, processing data.
And the instruction of user side makes all relay stations quit work, in a dormant state；3）Start, close with regard to password and user side
Explanation：After user side turns on the power switch, microcontroller obtains voltage, starts working.In the data that user side sends, it is
Encryption and prevent co-channel interference, we are also provided with password, because the password of each relay station, collection terminal is the same, therefore
Ensure that all relay stations in the system, the transmission of all collection end datas require.
In sum, after user side work, all relay stations, collection terminal need to carry out password check, relay station numbering core
Work to the numbering verification of, collection terminal, in the case of password, two numberings are all correct, just can transmit data, thus protect
Accuracy and the reliability of data are demonstrate,proved.
After the completion of user's end data all transmits（All relay stations are already at resting state）, user should close power-off
Source switch, user side quits work, and waits the data acquisition of next time.
The program summary of relay station microcontroller
The power supply of relay station is always on, and relay station is in the state of intercepting, and therefore relay station can detect user at any time
Whether end has instruction to be transferred to this relay station.
The program of the microcontroller of relay station is mainly：When receiving enabled instruction, first determine whether password and relay station
Numbering（The program of relay station is numbered with relay station already provided with password in advance）If password is correct, relay station is compiled
Number correct, relay station is started working, and time delay 1 second, and the instruction sending gathered data is to the collection belonging to this relay station system
End, collection terminal sends data according to order successively.We are in advance in a program already provided with this relay station system acquisition end
Quantity, and these collection terminals are equally provided with numbering, and being sequentially transmitted data is to be sequentially transmitted according to the numbering of collection terminal.
After the completion of the data transfer of this relay station, issue instructions to collection terminal first and complete data transmission, without connecing
Receive the instruction closing relay station, relay station keeps working condition, and enters relay state（I.e. relay state）, wait
The data receiver of next stage relay station and transmission, we are provided with a time delay in this process, that is, after time delay 1 second, receive
With the data sending next stage relay station.
Receive after closing the instruction of relay station in relay station, also can time delay 1 second, the microcontroller of relay station and transmitting connect
Receive module in a dormant state.
The program summary of collection terminal microcontroller
Collection terminal micro-controller program is broadly divided into two parts, and one is the program of acquisition module gathered data, and two is that collection terminal passes
Send the program of data, discuss separately below：1）The collection of acquisition module data：Acquisition module 22 gathered data is timing acquiring
, because the power supply of collection terminal is always on, microcontroller is work all the time, and microcontroller is provided with second signal and occurs
Device, produces accurate second signal, this second signal as a signal source of microcontroller, it can according to the needs of program,
, it is also possible to generate the timer of a stipulated time, this timer requires to be set according to user for date of formation, time data
Fixed, what such as we set is 10 minutes intervalometers, below our program be all analyzed with this 10 minutes intervalometers.Separately
Outer second signal also can date of formation, the timing of time, the depositor of microcontroller stores this date, time data, root
According to second signal, this data of modification per second, data so in a register should be just synchronous with Beijing time.If reached
Intervalometer timings in 10 minutes in microcontroller, microcontroller turns on power supply o controller 23, so that acquisition module
22 obtain voltage, and acquisition module can be carried out the collection of data, typically set acquisition time as 1 second（Certainly according to collection
Module this acquisition time of difference can also be changed）, the data that acquisition module collects, it is sent to microcontroller, first micro-control
Device processed is processed to this data（Gathered data can carry out A/D conversion in microcontroller it would be desirable to be collection number
Digital data, such as temperature should be .** DEG C of * *, and atmospheric pressure is * * .**KP, and wind-force is * * .**M/S etc., certainly, digital number
According in be not tape unit）, the relay station being provided with this collection terminal in advance in collection terminal program is numbered, collection terminal is numbered, adopted
Collection type, so we are just easy to take out " relay station numbering, collection terminal numbering, date, time, grab type ", add just
The just gathered data of collection, be just readily generated one " the relay station numbering+collection terminal numbering+date+time+grab type+
One character string of data ", has a space between each data of this character string, like this " No. 04 point 2016- in No. 03 station
5-24 17:22:33 wind power collectings 0.33 " are in order to be stored in each word of data base in computer mask data later
Section.After generating this character string, microcontroller stores in SD storage card with regard to this character string, and in storage, program can detect
Whether with the presence of same date, same to hour, with minute data（Also detection date, hour, the number of minutes are received）If do not deposited
Increasing record and stored, if it does, covering record storage, this ensures that thering in SD storage card same date with little
When only have a record with minute, do not have repeat record exist.In addition the data of this storage be according to the date, the time big
Little arrange from small to large.After timing in 10 minutes terminates, after time delay 1 second, microcontroller cuts out power supply o controller 23,
Acquisition module 22 is made to lose voltage and quit work, microcontroller resets to 10 minutes intervalometers simultaneously, 10 minutes intervalometers
Restart timing, wait next 10 minutes gathered datas again.We are stored due to the capacity of SD storage card this
Much bigger for individual character string（The storage card of such as 8Mb）, therefore in the data of SD storage card storage, the data volume of a day is also only
Only it is less than 7Kb, this SD storage card can store the data of 20 years about at least, this just extracts data for user and provides
Very big temporal flexibility.2）The transmission of acquisition module data：After collection terminal receives transmission data command, first determine whether close
Whether code, relay station numbering, collection terminal numbering are correct, if correctly, collection terminal can transmit data to relay station.At this moment microcontroller
Device stops the timing of 10 minutes intervalometers, then wakes up microcontroller and transmitting and receiving module, microcontroller is from SD storage card
Read the first data to be transmitted, and then read the second data and transmitted, by that analogy, therefore transmission data is one
Bar one is sequentially transmitted, and the speed due to data transmission is 512 bytes per second it is assumed that needing to transmit 1000 data, every
Data is 45 bytes, and the time of needs is about 90 seconds.There is individual problem in the middle of this, between collection terminal group, whether can produce misinformation
Send？Said before this we, relay station is to send an instruction in receiving data, not only wrapped in this instruction
Containing the instruction sending data, also comprise the numbering needing the collection terminal sending data, therefore between collection terminal group, transmission data is
Misfeed will not be produced.After the completion of data all transmits, the microcontroller of collection terminal can send a data transmission and complete
Instruction, relay station receives this and instructs and be transferred to computer, can send next collection terminal again and pass after confirming through user
Send the instruction of data.The SD storage card just having transmitted data resets（Delete all data of the original storage of SD storage card）, and
And the transmitting and receiving module of collection terminal, microcontroller can in a dormant state, 10 minutes intervalometers of this collection terminal can reset, weight
Newly start timing, repeat above-mentioned storing process；3）Need the problem of explanation：Each relay station in collection terminal group is numbered, is respectively adopted
Collection end numbering, each grab type differ, and this is embodied in the difference of programming program.
