4) data transparent transmission
LoRa wireless networks support the network communication protocol of independent research, and the saturating of data is provided the user on the basis of this agreement Bright transmission, supports often to wrap the user data of at most 120 byte lengths of transmission.
After the completion of networking, multilist collection copies communication interface converter and passes through behaviour of the LoRa modules realization to each node in network Make and control, the message for meeting CJ/T 188-2004 communications protocol formats can be directly transmitted to each LoRa wireless communication modes Meter carries out data reading system, and the response message that meter is returned is uploaded to multilist collection and copies communication interface converter by LoRa modules, Copied after communication interface converter encapsulates response message by multilist collection again and upload concentrator.
The important technological parameters of LoRa modules are as follows:
Working frequency points scope:470~510MHz;Emission state power consumption≤100mA, reception state power consumption≤20mA;Operating voltage:3 ~3.6V;Transmission power<16dBm;Serial ports form:UART, baud rate 9600bps, 8 data, no parity, 1 stopping Position;Wireless communication rate:0.8kbps;Transmitting distance:> 2500m(Open field);Appearance and size:40 mm× 27.5mm。
The interface parameters of LoRa modules includes following:
void LoRa_Init(BYTE nPort):LoRa module initializations

As shown in Fig. 2 LoRa radio meter registers are using there is address pattern copy reading, flow is comprised the following steps:
Step(1), after the completion of LoRa module wireless networkings, after the data reading system order to certain block meter is received, enter first Row packet parsing, identification meter address(That is node archives);
Step(2), whether decision node archives have been registered for, if unregistered, the node registered and to be automatically added to LoRa wireless Network networking again, return to step(1);If registered, judge whether current time is small more than M away from the last time copy reading success time When, if being more than, data reading system order is directly forwarded to the meter, otherwise will then cache last time copy reading success when response report Text uploads multilist collection and copies communication interface converter, terminates this and checks meter;
Step(3), wait meter to return to response message in timeouts, if receiving response message, into step(5);If Response message is not received yet beyond the time limit, and the increase of the copy reading frequency of failure is once;
Step(4), judge whether the same day is more than n times to the copy reading frequency of failure of the meter, if being less than, data reading system is forwarded again Order, return to step(3);If being more than, the data reading system order to the meter will be no longer responded in the same day;
Step(5)If receiving response message, uploaded multilist collection and copy communication interface converter and cache, while minute book The secondary copy reading success time, terminate this and check meter.
Because there is low-power consumption wake-up mechanism in the node communication in LoRa wireless networks, therefore to single node(That is LoRa The meter of wireless communication mode)1 secondary data copy reading time about 10s or so(If data reading system order is forwarded by repeater The copy reading time is longer).It is up logical and multilist collection copies communication interface converter uplink communication mode generally power line carrier at present The time-out time of letter is shorter(Generally less than 6s), so after the completion of waiting radio meter register, concentrator will be unable to from upper because of communication overtime Row of channels obtains meter data.
For this problem, the present invention increased data buffer storage mechanism, i.e., often successfully copies in LoRa radio meter register flows Read one piece of meter, multilist collection copies response message that communication interface converter receives in addition to data feedback channel is returned, and will also delay automatically Deposit, the response message of last time caching is responded immediately to when the data reading system order from data feedback channel is received again, it is ensured that collection Success rate of the middle device from data feedback channel gathered data.
Further, since the meter of LoRa wireless communication modes is powered using battery at present, if frequently processing data copy reading refers to Order will increase power consumption, reduce battery, increase the O&M cost of live meter.For extension meter battery uses the longevity Life, the present invention devises LoRa wireless data copy reading protection schemes, refers to " shielding " data reading system unnecessary in the short time Order.The daily copy reading frequency of failure upper limit is provided with simultaneously to tackle the situation of failure of repeatedly checking meter, it is to avoid because meter faults itself, Artificial setting repeat caused by the factors such as mistake invalid checking meter and the loss of communication interface converter copied to multilist collection and overall is checked meter The obstruction of flow, lifts the efficiency of LoRa radio meter registers.LoRa wireless data copy reading protection schemes are as follows:
1)Multilist collection copies communication interface converter and may be configured as debugging mode or protected mode, is defaulted as protected mode;
2)Under debugging mode, data reading system order will be forwarded unconditionally, and holding time for debugging mode is settable, is set to 10 minutes integral multiples, maximum is supported 2550 minutes(In view of actual conditions, the daily 2:00 AM of debugging mode is automatically switched off);
3)In protected mode, it is within every M hours to the node in forwarding cycle, M hours for the successful node of copy reading The response message of caching is replied in copy reading.M needs to take into account data reading system cycle and meter response times, because aqueous vapor hotlist meter is every Automatic storage accumulative hour one secondary data of storage of registration, i.e., 24 during its zero crossing, it is obviously 24 that M is maximum, and the too small then table of M values Meter same day response data copy reading order number of times is excessive, does not have reduction battery power consumption effect, and from terms of debugging angle, M minimums take Be 1, i.e. an at most data reading system order of response per hour.Consider actual conditions, M values are 4 in recommending the present embodiment;
4)In protected mode, to copy reading failure meter data reading system order on the day of at most forwarding n times, daily zero passage The copy reading frequency of failure for putting the meter resets, and next day counts again.In view of there is sporadic copy reading factors for failure, N is at least Should be 2, and if N values are excessive, still influence overall meter reading efficiency, generally higher than 5 times copy readings failure then may determine that be by The factor such as meter faults itself or artificial parameter setting mistake causes, therefore N maximums can be taken as 5.Consider actual conditions, recommend N values are 3 in the present embodiment.
To tackle the situation of LoRa radio meter register operation exceptions, when multilist collection copies communication interface converter in LoRa wireless networks When the multiple data reading system of multiple nodes fails, it may be possible to because LoRa module softwares failure, inherent parameters set it is improper etc. and Cause, be now necessary reset LoRa modules.If therefore the copy reading frequency of failure of all nodes in LoRa wireless networks adds up Reach K then reset LoRa module.Copying communication interface converter due to a multilist collection should at least support wireless to 32 pieces of LoRa The data reading system of the aqueous vapor hotlist meter of communication modes, 32 × 2=64≤K≤32 × 5=160 is understood by the span of above-mentioned N.Examine It is 100 to consider K values during actual conditions recommend the present embodiment.
