Step S40, the analytic accounting scale interval preset time period send connection request and are extremely covered in same wireless network
It is described from gauge table within lid scope.
Analytic accounting scale interval preset time period (such as：2S) send connection request to the same wireless network of analytic accounting scale
It is all from gauge table within network coverage.
Step S41, it is described that response message is generated according to the connection request from gauge table, and the response message is sent
To the analytic accounting scale.
Response message is generated from gauge table according to the connection request, meanwhile, which is sent to analytic accounting scale.
Step S42, the analytic accounting scale generate communication link according to the response message and the list of described address relationship map
Failed list is connect, and the communication connection failed list is sent to the main website server, the communication connection failed list
The address information of slave gauge table including communication connection failure.
Response message includes the address information from gauge table, and analytic accounting scale is believed according to all of acquisition from the address of gauge table
Breath is compared with address relationship map listing one by one, after the completion of comparison, remaining address relationship in address relationship map listing
The data message of map listing is the data message for being used to form communication connection failed list.
Step S43, the main website server according to the address information from gauge table send connection request to it is described from
Gauge table, it is described to send response message to the main website server from gauge table, so that establishing described from gauge table and the master
The communication connection of site server.
Communicating to connect failed list includes the address information of slave gauge table of communication connection failure.Main website server passes through this
Connection request is sent to corresponding from gauge table from the address information of gauge table with this from the address information of gauge table, should be from metering
After table receives connection request, response message is generated according to the connection request, and the response message is sent to main website server,
Thus, communication connection that should be between gauge table and main website server is successfully established, and should be directly transmitted from gauge table from gauge table
Data frame is to main website server.
Step S44, the main website server according to it is described from the address information of gauge table determine with it is described from gauge table away from
From recently and the analytic accounting scale within the same wireless network coverage, and control instruction is sent to the analytic accounting scale,
The analytic accounting scale is controlled to send connection request to described from gauge table, so that establishing the analytic accounting scale and leading to from gauge table
Letter connection.
Address information of the main website server by this from gauge table, and the address relationship that all analytic accounting scales are previously sent
The address information of analytic accounting scale in map listing, determines one with should be closest from gauge table and being in same wireless network
The analytic accounting scale of network, main website server send control instruction to the analytic accounting scale, after analytic accounting scale receives the control instruction, hair
Connection request is sent to be somebody's turn to do to being somebody's turn to do from gauge table from gauge table transmission response message to the analytic accounting scale, thus, should be from gauge table with being somebody's turn to do
Communication connection is established between analytic accounting scale, should be sent from gauge table from meter data frame to the analytic accounting scale.
The present invention passes through above-mentioned mode, it is ensured that causes to communicate to connect due to various reasons from gauge table with analytic accounting scale
After failure, main website server remains able to the slave meter data frame of the slave gauge table of collection communication failure, has reached regardless of assorted
When occur from gauge table and analytic accounting scale communication link Ei fail the problem of, whole kilowatt meter reading-out system can be adjusted automatically,
So that solving the problems, such as this, ensure the normal operation of kilowatt meter reading-out system.
The slave gauge table of the present invention is respectively provided with telecommunication module and proximity communication module with analytic accounting scale, dual logical
Believe module, it is ensured that the integrality and reliability of the collection of the data frame of kilowatt meter reading-out system of the invention.
Embodiment 5
Referring to Fig. 5, Fig. 5 is the flow diagram of remote meter reading method embodiment 5 of the present invention.
In embodiment 5, essentially identical with the basic step of above-described embodiment 1, difference is, the step S12
Afterwards, including：
Step S50, when the main website server and the analytic accounting scale communication link failure, the main website server according to
Described address relationship map list determine one it is closest and be in same wireless network coverage with the analytic accounting scale
Within slave gauge table, should from gauge table as new analytic accounting scale.
When main website server does not receive whole analytic accounting scale data frames, that is, being expressed as main website server and certain, some are led
Meter communications connection failure.
Address relationship map listing includes the address information of the address information and analytic accounting scale from gauge table.
After main website server and the communication connection of some analytic accounting scale fail, main website server is according to the analytic accounting scale
Address information and the analytic accounting scale are previously transmitted to believing from metering table address in the address relationship map listing of main website server
Breath is compared, and determines a slave meter closest with the analytic accounting scale and within same wireless network coverage
Scale, should be from gauge table as new analytic accounting scale.
Step S51, the main website server, which sends control instruction to the new analytic accounting scale, the control instruction, to be included
The slave gauge table address information of the slave gauge table within same wireless network coverage is in the new analytic accounting scale.
Main website server sends control instruction to new analytic accounting scale, the control according to the address information of new analytic accounting scale
The analytic accounting scale that instruction includes breaking down is sent in the address relationship map listing of main website server, removes failure
Other address informations from gauge table of analytic accounting scale and new analytic accounting scale.
Step S52, the new analytic accounting scale send connection request to it is described from gauge table address information it is corresponding from
Gauge table, it is described that response message is generated according to the connection request from gauge table, it is established that new analytic accounting scale with from gauge table
Between communication connection.
The present invention in analytic accounting scale is built with the first time from gauge table, according to close to wireless network cover by main website server
The address information of the near gauge table in lid scope center, sends control instruction to the gauge table, so that the gauge table is as main metering
Table.
The present invention can be according to the size and actual needs of wireless network coverage, in first time builds, same
