Abstract
The invention discloses a collecting device for self-adaptive reading according to the network state of an ammeter group. The technical scheme is realized by an acquisition terminal capable of reading the networking state of the routing module and a routing module capable of identifying the networking state of the ammeter. When the non-existing electric meters or fault electric meters are configured, the acquisition terminal cannot identify the abnormal electric meters, so that a large number of waiting communication overtime and reading channels are occupied, and the reading efficiency and the periodic data acquisition success rate of other normal electric meters can be greatly influenced. The acquisition terminal reads the periodic data of the normal ammeter by inquiring the networking state of the ammeter nodes in the routing module, and does not read the abnormal ammeter, so that the channel occupation and communication waiting of the abnormal ammeter are avoided. And after the abnormal ammeter is recovered to be normal, automatically re-identifying the networking state, and reading data of all the networked successful ammeter to realize the self-adapting reading of the networking state of the ammeter.

Technical Field
The invention relates to the technical field of communication, in particular to a method for self-adapting reading according to the network state of an ammeter group.
Background
The meter data reading by the power line carrier is widely applied to the power grid. The acquisition device comprises an acquisition terminal, a routing module and an ammeter. However, in actual operation, the master station configures the acquisition terminal with an inexistent ammeter or a fault ammeter, so that the ammeter cannot be read, the acquisition terminal of the abnormal ammeter cannot be identified in advance, and the ammeter data is generally read periodically according to the normal ammeter. After the terminal sends a reading command to the routing module, the terminal can reply after waiting for a period of time until the routing module replies that the communication is overtime or the reporting task state is that the slave node does not respond, and the terminal can release the meter reading channel.
In the process of reading in the terminal, for the ammeter which fails to read for many times, the ammeter can be marked as a fault ammeter according to the previous reading failure record, and the reading of the ammeter is stopped. However, the method still needs to be judged through a plurality of reading periods, and the accuracy of the identification result cannot be ensured, so that missing reading is easy to cause. And after the fault of the abnormal ammeter is repaired, the terminal cannot immediately recover reading.
Abnormal electricity meters cannot be identified in advance before meter reading, communication is required to wait for overtime, so that a reading channel is occupied for a long time, and other normal electricity meters cannot be read on time; after the fault of the abnormal ammeter is repaired, the ammeter cannot be read in time, and the reading efficiency and the success rate of periodically collecting data of the ammeter in the whole area are greatly influenced.

step 3: the routing module activates the ammeter slave node to network, and after the ammeter slave node and the routing module are successfully networked, the routing module stores the related information of the successfully networked node;
step 4: the terminal inquires networking node information list information in the routing module;
step 5: the terminal judges according to the networking information of the ammeter, and when the number of the ammeter is in the networking node information list, the normal periodic data reading of the ammeter is carried out, otherwise, the ammeter is considered to be absent or fault, and the periodic data reading is not carried out on the ammeter.
Furthermore, when a new ammeter node and a routing module are successfully networked in the terminal operation process, or the network is successfully networked with the routing module after the abnormal ammeter fault is repaired, the routing module actively reports the change information of the slave node networking to the acquisition terminal, and after the terminal receives the change information, the terminal inquires the node information of the successfully networked node in the route again, and the newly added ammeter node is added. And then periodically re-performing meter reading.
Furthermore, when the network connection state of the routing module is disconnected during the operation of the terminal, the routing module actively reports the change information of the slave node network connection to the acquisition terminal, and after receiving the change information, the terminal inquires the node information of the successful node which is connected in the routing again, and deletes the abnormal ammeter node. And then periodically re-performing meter reading.
Furthermore, when the ammeter replies to deny, the protocol does not support or when reading a certain ammeter continuously 3 times overtime or route report task state, the acquisition terminal actively inquires the networking information of the routing module from the node once, and then periodically reads the meter again.
Furthermore, the acquisition terminal can read out the list information of the electric meters which are not networked by the terminal on a screen display or through a remote network port, so that maintenance staff can quickly find out the electric meters which cannot be read out for maintenance or replacement.
The beneficial technical effects of the invention are as follows: the collecting device can adaptively read only the normal ammeter when the meter which cannot be read or the fault ammeter exists on site, avoids communication timeout waiting caused by the meter which cannot be read or the fault ammeter, improves the utilization rate of the reading collecting channel, and effectively ensures the reading efficiency of the ammeter and the success rate of periodically collecting data.
