The data message at three table ends 10 is sent to and concentrator by the data message at 13 three table ends 10 of collection, two repeaters 13 again
11 repeaters 13 linked, concentrator 11 can assign transmission data set to repeater 13 and copy order, in linking with concentrator 11
The direct data message for forwarding three table ends 10 of order is copied to concentrator 11 according to data set after device 13, copying for whole system is reduced
The table time.Certain table end 10 can not also be directly connected to concentrator 11 by repeater 13, and direct pair of concentrator 11 links with it
Table end 10 carries out meter reading, to obtain the data message at corresponding table end 10.
The low-consumption wireless MANET kilowatt meter reading-out system 1 of present embodiment further includes hand-held set 14, hand-held set 14 can with it is each
Individual table end 10, concentrator 11 and each repeater 13 link, and can be set each table end 10, concentrator 11 and each in
After the communication channel and relevant parameter of device 13, and it can be used for supplementing meter reading.
There is LoRa wireless modules in each of which table end 10, concentrator 11, each repeater 13 and hand-held set 14,
Its power consumption is effectively reduced, and then reduces the power consumption of total system, the repeater 13 of present embodiment only has single wireless mould
Block, links with table end 10, concentrator 11 or hand-held set 14 and uses same frequency, in using upper relatively simple, if any adjacent system,
Can be by the way of point channel (i.e. frequency division multiplexing FDMA) or (i.e. the time-division is multiple using stagger meter reading period and meter reading day of staggering
With TDMA) avoid signal conflict.Each right table end 10 and each repeater 13 use csma/conflict
Detection protocol (CASMA/CA), it is to avoid route between the repeater 13 at each table end 10 table end 10 corresponding with link or mutually
Signal conflict is produced between two repeaters 13, and reaches two-way communication.Each table end 10, concentrator 11 and each repeater
13 have multiple channels, and each channel width is 250kHZ.Each table end 10 and repeater 13 are powered using battery, concentrator
11 use civil power or solar powered, it is to avoid can not find suitable power supply in system installation environment and cause installation difficulty,
Avoid the difficult in maintenance of later stage.Each table end 10 and repeater 13 have real-time clock, and concentrator 11 can be to each
Individual table end 10 and repeater 13 are calibrated.Each table end 10, concentrator 11 and repeater 13 use watchdog technique, improve
The reliability of total system.The background manager 12 of present embodiment is using browser/server framework (B/S), hand-held set 14
Use WINCE6.0 systems or Android system.
Each table end 10, concentrator 11 and each repeater 13 have Setting pattern and mode of operation, Setting pattern
With frequency is set, mode of operation has a working frequency points, it is triggered after, each table end 10, concentrator 11 or each relaying
The frequency of device 13 automatically switches to setting frequency, is introduced into Setting pattern, can be in every with 14 pairs of hand-held set in predetermined set time
One table end 10, concentrator 11 or each repeater 13 carry out parameter setting；If exceeding predetermined set time or being provided with
Afterwards, the frequency at each table end 10, concentrator 11 or each repeater 13 automatically switches to working frequency points, each table end
10th, concentrator 11 or each repeater 13 enter mode of operation.
The LoRa wireless modules of each table end 10 and repeater 13 have listening functions, and being listened in some cycles is
No to have aerial lead code, also referring to Fig. 2 and Fig. 3, it is the low-consumption wireless MANET meter reading of the embodiment of the application one
The table end 10 of system 1 or the first working timing figure of repeater 13 and the second working timing figure；If as illustrated, listening to sky
Middle lead code, each table end 10 or repeater 13 switch to reception pattern.Connect when each table end 10 or repeater 13 enter
During receipts pattern, judge whether data-signal is sent to table end 10 or repeater 13 using fast address matching algorithm, if being judged as not
Table end 10 or repeater 13 are destined for, then switches to park mode, stops receiving remaining data message.It is sent to if being judged as YES
Table end 10 or repeater 13, then be continuously reception pattern, and receive remaining data message.Refer to Fig. 4 in the lump again, it is this Shen
Please an embodiment low-consumption wireless MANET kilowatt meter reading-out system 1 table end 10 or the 3rd working timing figure of repeater 13；Such as
Shown in figure, if without aerial lead code is listened to, each table end 10 or repeater 13 switch to park mode.
Each right table end 10 can enter Setting pattern and set the time that table end 10 enters deep power down mode, stop in depth
During sleep mode, the LoRa wireless modules at table end 10 will not be intercepted, only the collection of responsible data message.Now, concentrator 11
And the repeater 13 linked with it is issued an order without normal direction table end 10.If the same day of concentrator 11 orders when not sending school to table end 10
When making, the same day of table end 10 will not enter deep power down mode；If the same day of concentrator 11 orders when sending school to table end 10, table
The same day of end 10 can enter deep power down mode according to the setting time of deep power down mode, table end 10 when deep power down mode compared with
It is in park mode more power saving.
Please refer to fig. 5, it is the table end 10 of the low-consumption wireless MANET kilowatt meter reading-out system 1 of the embodiment of the application one
Workflow diagram；As illustrated, table end 10 is by real-time clock waking-up, table end 10 exits park mode and enters normal work mould
Formula；Table end 10 start check current time whether be deep power down mode setting time, if it is, check the same day whether by
During 11 school of concentrator, if during by school, table end 10 carries out data sampling and opens real-time clock waking-up function, then reenters
Park mode；If current time is not the setting time of deep power down mode, table end 10 is then intercepted, if intercepting process
Middle to find aerial lead code, table end 10 enters reception pattern, and operation fast address matching algorithm judges whether data message is hair
Toward table end 10, if it is, receiving data left information, called out while handling communications command, data acquisition and opening real-time clock
Wake up, subsequently into park mode.If it is not, then stopping receiving data left, while carrying out data sampling and opening real-time clock
Arousal function, subsequently into park mode.
In summary, in one or more embodiments of the application, the low-consumption wireless MANET kilowatt meter reading-out system of the application
Reach that low-power consumption, high reliability, remote, MANET, simple installation, maintenance cost be low and two-way number using LoRa wireless modules
