[0052] 上述集中器20接收主站100的读表指令后,将该读表指令发送给下一级的采集器30 ;接收该读表指令的采集器30通过多跳路由的方式,再进一步转发其他的采集器30 ;接收到该读表指令的采集器30可采集与其关联电表的电表参数,该电表参数至少包括电表所显示的用电度数等;一个采集器30可与一个或多个电表关联,采集电表参数;该采集器30在采集到电表参数后,通过其他采集器30转发或者直接反馈给集中器20 ;该集中器20在收集到CFDA网络中电表参数后,通过GPRS网关发送给主站100,以便主站100完成对电表进行优化调度、控制或者计费等功能。 After [0052] The above table read instruction concentrator 20 receives the master station 100 transmits the table read instruction to the next stage collector 30; receiving the read instruction table 30 of the collector by a multi-path routing, and further other forwarding collector 30; receives the read command table collector 30 can collect the parameters associated with the meter the meter, the meter parameters comprises at least a degree of electrical meter and the like are displayed; 30 a may be one or more collectors meter associated collection meter parameters; the collector 30 after collection to the meter parameters forwarded through another collector 30 or directly back to the concentrator 20; the concentrator 20 after collected CFDA network meter parameters sent through GPRS gateway to the primary station 100 to primary station 100 completes the meter to be optimal scheduling, billing control, or other functions.

[0053] 上述CFDA自组网信息采集平台,在进行自动化抄表之前,需要先进行CFDA自组网。 [0053] The CFDA ad hoc network information collection platform, prior to automated meter reading, we need to be CFDA ad hoc networks.

[0054] 上述主站100可用于规划网络结构,确定微蜂窝地域及数量,形成蜂窝结构;并根据该蜂窝结构确定CAC的编码方案;以及根据该CAC的编码方案,分配频率资源给CAC,确定DAU的物理ID及逻辑ID,形成两者的ID映射表。 [0054] The master station 100 may be used for planning the network structure, determining microcell area and number, to form a honeycomb structure; and the honeycomb structure is determined CAC coding scheme according to; and according to a coding scheme of the CAC allocates frequency resources to the CAC, determined DAU logical ID and physical ID, the ID mapping table formed both.

[0055] 设置有CAC的集中器20,可从该主站100中下载该ID映射表,并在确定所有的DAU都在线后,指示CAC建路由,组网络。 [0055] CAC provided with a concentrator 20, the ID mapping table can be downloaded from the master station 100, and after determining the line are all the DAU, indicating CAC build routing, network group.

[0056] 上述准备组网模块201具体用于:接收ID映射表后,确定所述ID映射表是为批量或者增量;当为增量时,根据所述ID映射表判断是否有相应的主动加入记录;如有,则发送场强收集指令;否则,作为批量处理;当为批量时,根据所述ID映射表计算并确定信道,并发送组网信标进行组网。 [0056] The preparation networking module 201 is configured to: after receiving the ID mapping table, the mapping table to determine the ID is for the bulk or incremental; increments when, if there is a corresponding ID mapping table according to the active Analyzing was added record; if so, transmits field intensity gather instruction; otherwise, as a batch process; when the batch is calculated according to the mapping table ID and determines a channel, and transmits a beacon network for networking.

[0057] 上述准备组网模块201接收到采集器30的ID映射表后,根据该ID映射表可确定新加入网络的采集器30的数量,当新加入网络的采集器30数量较多时,可确认为批量;当新加入网络的采集器30数量较少时,可确认为增量。 [0057] After the above preparation networking module 201 receives the acquisition ID mapping table 30, based on the ID mapping table of the new added network may determine the number of collector 30, when a newly added network 30 larger number of collectors, may batch is confirmed; 30 when there is less number of new added network acquisition, confirmed increments. 上述批量与增量的判定,可根据预先设定的数值进行。 Determining incremental quantities of the above, it can be based on a preset value. 该数值根据实际情况而定。 This value depends on the actual situation.

[0058] 当为批量时,上述准备组网模块201针对该ID映射表中的采集器30进行组网,计算并确定传输信道并发送组网信标。 [0058] When in the batch, prepared as described above for the networking module 201 for networking the acquisition ID in the mapping table 30, calculates and determines a transmission channel and transmits network beacon.

[0059] 当为增量时,上述准备组网模块201再进一步根据该ID映射表判断上述采集器30是否有主动加入网络的记录;如有,则可通过场强收集模块202直接发送场强收集指令,收集该采集器30的场强信息,使其加入网络。 [0059] When increments, prepared as described above and further the networking module 201 determines based on the above-described collector ID mapping table 30 is added with active network records; if, 202 can be sent directly by the field intensity field collection module collection instruction to collect the collector field strength information 30, so as to join the network. 否则,可将没有主动加入网络记录的采集器30作为批量处理。 Otherwise, the active may be added to a network without recording the collector 30 as a batch process.

[0060] 该主动加入网络的记录,即为未入网的DAU(采集器30)主动向CAC(集中器20)发起入网请求的记录。 [0060] The active record added network, network that is not the DAU (collector 30) initiates a network access request to the CAC (concentrators 20) recording. 该请求入网的过程即为“游离入网”功能,其具体过程详细描述如下: Process the request network is "network free" function, the specific process is described in detail as follows:

[0061] 在组网完成后,可能存在漏点(即有DAU未入网)的情况;同时,在已经组网的网络使用过程中,随时都可能有新的DAU节点需要加入。 [0061] After the network is completed, the leak may be present (i.e., there is not network DAU) case; simultaneously, networking has been in the process of using the network, any time there may be need to add new nodes DAU. 上述两类DAU节点处于游离状态,需要主动申请入网。 DAU above two node in a free state, it is necessary to apply the active network.

[0062] 上述游离的DAU节点在每个频道组的最后一个频道发送主动入网请求,然后进入扫描接收状态,扫描一定时间(根据时隙号取值约6〜10分钟)后,如果没有收到应答,将切换频道再发入网请求,直到所有频道组发完为止。 [0062] The free DAU node sends a last active network access request channel in each channel group, and then enters the receiving state scanning, scanning a predetermined time (time-slot number according to the value of about 6~10 minutes), if not received response, the network access request retransmission switch channels, the channel group until all the far end. 在网状态的DAU节点如果收到游离DAU节点的入网请求,会在每个频道组的第一频道进行应答。 DAU nodes of a mesh network access request is received if the state free DAU node will respond in a first channel in each channel group. 游离的DAU如果接收到其它DAU节点应答,记录应答DAU节点地址(ID)保存到场强表,记录的格式和信标场强表一致。 Free DAU DAU other node if the received response, the response recorded DAU node address (ID) stored field strength table, and the beacon format consistent field strength table records. 直到所有应答时隙完毕,然后从能联系上的DAU节点中,选择一条最优路径上报CAC。 Until all the response time slots is completed, and then from the DAU to contact the node, select an optimal path reported by CAC. CAC将记录该DAU的ID,并根据该ID判断对应的DAU是否属于其网络管辖范围;如是,则对该DAU进行场强收集和配置;否则,不予处理。 CAC will record the DAU's ID, and determines whether the DAU corresponding fall within its jurisdiction based on the network ID; yes, then the field for collecting and DAU configuration; otherwise, no treatment. 如果上述游离DAU在侦听期间,接收到组网信标,则放弃入网申请,进入信标组网过程。 If during the listening of the free DAU received beacon network, network application is abandoned, the process enters a beacon network.

[0063] 上述场强收集模块202具体用于:在指定频道组进行扫描;在接收信号帧后,判断所述信号帧是否合法;在所述信号帧合法时,记录所述信号帧中包含的场强信息。 [0063] The field collection module 202 is configured to: scan the specified channel group; after receiving the signal frame, whether the signal frame is determined valid; valid when the signal frame, recording the signal frame contained field strength information. 上述场强收集包括:发送组网信标后的场强收集以及发送场强收集指令后的场强收集。 Said field intensity collector comprising: a field strength and the field strength was collected after collecting the transmission field strength gather instruction after transmitting a beacon network.

[0064] 该发送组网信标后的场强收集是指,当上述准备组网模块201发送完组网信标后,上述采集器30需对该组网信标分级进行转发,且先收到组网信标的采集器30可对外发送场强信息;该场强收集模块202可指定频道组内扫描,接收其附近的(比如第一层等)采集器30发出的场强信息;接收后,进行帧的合法性验证,可先判断该接收的实际信道(号)是否为指定信道(号),再判断中心网络ID(集中器ID)是否正确,在该实际信道为指定信道且中心网络ID正确时,则确定为合法帧;则可存储该帧并记录场强信息;此时,采集器30对组网信标的转发周期还未结束,该场强收集模块202也还未发出场强收集指令。 [0064] After collection of the field strength of the transmission network standard letter means that when preparing the above-described network networking module 201 after sending a beacon, the above-mentioned collector 30 need to be forwarded to the network beacon classification, and to close the acquisition beacon network 30 may send the external field intensity information; this field 202 can specify the collection module group within the channel scanning, the received field strength information in its vicinity (such as the first layer or the like) sent by the collector 30; after receiving , legality verification frame, can first determine the actual channel of the received (No) whether the designated channel (number), and then determines the central network ID (concentrator ID) is correct, the actual channel to the specified channel and the hub when the ID is correct, the frame is determined as legitimate; and records may be stored in the frame information field; At this time, 30 pairs of collector forwarding network beacon period has not ended, the collection module 202 also field field has not been issued collection instructions.

[0065] 上述场强收集模块202可在该组网信标的转发周期结束后,发送场强收集指令,进行场强收集。 [0065] The collection module 202 may be field intensity at the end of this period the forwarding network beacon, the transmission field strength collection instruction, for field collection. 该组网信标的转发周期,可根据采集器30进行组网信标转发的圈(层)数进行计算。 The forwarding network beacon period, the beacon can be forwarded ring network (layer) is calculated according to the number of collector 30.
