For realizing equipment association network access, the management of the equipment in the power distribution station area based on the new aging table comprises the following steps:

and finally, after equipment MAC address learning is completed, an aging timer of the equipment is set and station resources are configured, an association confirmation message is generated, and the association confirmation message is sent to the equipment station so as to realize the association networking of the equipment.
In this embodiment, the device site refers to a newly accessed device, the setting of the aging timer may be that the aging timer is set after the device sends an aging message, if the aging message includes aging timing, the aging timer is set according to the time, and if the aging message does not include aging timing, a default value may be adopted to refer to aging time.
To facilitate the description of the scheme to study the HPLC or dual mode local communication network as shown in fig. 2, a multi-level tree network is formed in a single mode of operation. The first level is a Central Coordinator (CCO), the second level is a proxy site (PCO), and the third level is a Site (STA).
Referring to fig. 3, to implement device association network entry, an association request message is generated by a new device (STA), and its MAC address and aging time are declared in the message, and the message is sent to a high-level proxy station (PCO 2). After receiving the association request message, the high-level proxy station regenerates and forwards the message to its own proxy node (PCO 1). After receiving the association request message, the Central Coordinator (CCO) processes the association request, learns the MAC address of the equipment in the current aging table in the CCO, sets an aging timer corresponding to the MAC address, configures site resources to generate an association confirmation message, and sends the association confirmation message to the agent site of the lowest level. And after the lowest level regenerates the message, sending the message to the proxy site of the next level. And the last stage of proxy station processes and generates a new association confirmation message and then sends the new association confirmation message to the equipment Station (STA) requesting to access the network, so as to complete the association network access of the equipment.
In the implementation process, the association request message sent by the equipment station is obtained; based on the association request message, performing corresponding equipment MAC address learning, setting an equipment aging timer and configuring site resources in the new aging table; after equipment MAC address learning is completed, an aging timer of equipment is set and station resources are configured, an association confirmation message is generated, and the association confirmation message is sent to the equipment station so as to realize equipment association network access.

In some embodiments, the automatic file update may also be performed after the device is connected to the network, referring to fig. 4, fig. 4 schematically illustrates a flowchart of the automatic file update and the network connection of the device in the distribution area according to an embodiment of the present application. The management of the distribution area equipment based on the new aging table comprises the following steps:
firstly, acquiring the network state of equipment;
wherein the device network status includes all site activity information; the acquiring the network state of the device comprises: judging whether the station is active on line or not by the first proxy station according to the discovery list message sent by each station in a fixed period, obtaining station active information, and sending the station active information to the second proxy station through the heartbeat detection message in the fixed period; and the second proxy station gathers the heartbeat detection messages of the first proxy station to obtain active information of all stations.
In this embodiment, the discovery list is a list maintained by each node for storing information of other nodes adjacent thereto. Network status may be maintained based on discovery list messages and heartbeat detection messages, with high-level proxy stations referred to as near Station (STA) relay agents (PCOs) and low-level proxy stations referred to as near Central Coordinator (CCO) relay agents (PCOs). Referring to fig. 2, a high-level proxy station (PCO 2) determines whether the station is active online according to a discovery list message periodically sent by each Station (STA), sends station active information to a low-level proxy station (PCO 1) through a heartbeat detection message periodically, and after the low-level proxy station gathers the heartbeat message content of the high-level proxy station, sends all the perceived station active information to a Central Coordinator (CCO). To obtain the device network status.

According to the equipment activation times in the aging time, the maintenance of the network state of the station in the aging table can be realized, and the requirements of various production equipment can be met.
Then judging whether the aging time of the equipment is up; deleting the equipment information in the new aging table under the condition that the aging time of the equipment is reached; and re-acquiring the network state of the device under the condition that the aging time of the device is not reached.
In this embodiment, it is determined whether the aging time arrives, and if so, the device record is deleted in the new aging table. If the aging time is up, the network state of the equipment is returned to be acquired, and the equipment is circulated again until the aging time is up.
In the implementation process, by setting different aging times according to the communication requirements of different equipment types, in the aging time, the heartbeat message triggering mechanism for updating the aging table caused by the change of the network state is realized, so that the file is automatically updated in the aging table.

firstly, updating corresponding aging time in the new aging table to obtain new aging time;
then, judging whether the new aging time is reached; deleting corresponding equipment information in the new aging table and recovering corresponding site resources under the condition that the new aging time is reached; and in the case that the new aging time is not reached, redetermining the active state of the station in a complete heartbeat cycle time.

If the CCO detects that the station STA in the offline state becomes active again in the aging timing, it is determined again that the STA is in the online state, and the aging timer is reset.
In some embodiments, the power distribution substation equipment management method further includes:
firstly, determining the active state of a station in a plurality of heartbeat cycle times in the timing of an aging timer of a corresponding device;
and then, under the condition that the active states of the station in a plurality of heartbeat cycle times in the timing of the aging timer of the corresponding equipment are not active, deleting the corresponding equipment information in the new aging table, and recovering the corresponding station resources.
In this embodiment, if the CCO does not receive the packet of the STA at the station in multiple heartbeat periods in the aging timing, that is, the number of active times of the STA at the station is 0, it is determined that the STA at the station is in a non-network-access state, the MAC address of the device is aged, the device record is deleted in the new aging table, and the station resource is recovered.
In the implementation process, the aging table can maintain the site network state according to the equipment activity times in the aging time. After the aging time arrives, the aging table can timely recover the site resources, and the resource utilization rate is improved.
