Description

Method and device for obtaining wind farm networking equipment list

technical field

The present invention relates to the technical field of wind power, in particular to a method and device for obtaining a list of networked equipment of a wind farm.

Background technique

With the rapid development of science and technology, wind power generation technology is becoming more and more mature. The current overall development trend of wind farm units connected to the grid is large-scale and area-oriented. A networked wind farm or area can usually accommodate hundreds of devices (including: wind power Genset controllers and other related data acquisition and peripheral support equipment), due to hardware limitations, or for security and other management reasons, these devices cannot be installed or disabled SSDP protocol (Simple Service Discovery Protocol, Simple Service Discovery Protocol) . For example, the controllers currently used in wind farms are usually the following:

1. Most of the PLC controllers of BECKHOFF, Germany, are used for the control of wind turbines, peripheral converters and transformer equipment;

2. Siemens PLC equipment is used for some control in other occasions;

3. Other Windows-based control devices, some of which have the conditions to install SSDP service, must also close this service or not install this service, because the safety regulations of the power grid do not allow Windows devices to be used in the running network.

Since these controllers do not support the SSDP protocol, it becomes very difficult to search and maintain a list of networked control devices in wind farms.

In order to be able to search for a list of all networked devices in the wind farm, broadcasting is used to search for devices in the entire network segment in the prior art, but this leads to heavy network load, long search delay, and low efficiency. For example, for a wind farm with 20,000 LAN addresses, it takes about five minutes to search for all devices by broadcasting.

Detailed ways

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

Fig. 1 is a schematic flowchart of a method for obtaining a wind farm networked device list provided by an embodiment of the present invention; Fig. 2 is a method for obtaining an activated device list storing all activated networked devices in a wind farm provided by an embodiment of the present invention Schematic flow diagram; FIG. 3 is a schematic flow diagram of obtaining an activated device list according to an original device list provided by an embodiment of the present invention; referring to the accompanying drawings 1 to 3, it can be known that this embodiment provides a method for obtaining a list of networking equipment in a wind farm. The obtaining method is used to obtain the list of networked devices of the wind farm under the condition of ensuring the network communication quality of the wind farm. Specifically, the method includes:

S101: Scan the network address pool of the entire wind farm to obtain an activated device list storing all activated networking devices in the wind farm;

Specifically, the network address pool of the entire wind farm can be scanned in a preset broadcast form, wherein the network address pool includes the address information of the networked device to be activated, the address information of the networked device to be activated, and the neighbors to be scanned The address information of networked devices, etc., can obtain the activated device list through the overall scan of the network address pool. The activated device list includes all activated networked devices in the wind farm. It should be noted that the activated networked devices Normal data communication is possible, while inactive networked devices cannot perform normal data communication.

This embodiment does not limit the specific implementation of obtaining the activated device list, and those skilled in the art can set it according to specific design requirements, for example, while scanning the network address pool, detect the network address corresponding to each address information The working status of the device, according to the working status of each networked device, the activated networked device is obtained, and the activated networked device is stored, and the activated device list can be obtained; in order to ensure the accuracy and reliability of the activated device list, it is relatively Preferably, the network address pool of the entire wind farm will be scanned in a preset broadcast form to obtain an activated device list storing all activated networked devices in the wind farm, which is set to specifically include:

S1011: Scan the network address pool of the entire wind farm to obtain an original device list storing all networked devices in the wind farm;

Specifically, the network address pool of the entire wind farm may be scanned in a preset broadcast form to obtain an original device list, wherein the original device list includes activated networked devices and inactive networked devices.

Wherein, the preset broadcast form is, for example, sending ARP broadcast packets at intervals. That is to say, after sending the first ARP broadcast packet, pause for a while, and then send the second ARP broadcast packet. In this way, too many broadcast packets are distributed on the network, resulting in heavy load.

S1012: Obtain an activated device list according to the original device list.

Since the original device list includes activated networked devices, after the original device list is obtained, the original device list can be analyzed and processed, so that the activated device list can be obtained. Specifically, activation will be obtained according to the original device list The device list is set to specifically include:

S10121: Send an access request to all networked devices in the original device list;

Wherein, the access request can be sent to all networked devices through the scanning method of the preset address resolution protocol ARP, and the access request is used to identify the activated networked device among all the networked devices in the original device list, specifically, the unactivated After receiving the access request, the networked device cannot return a response message. Therefore, according to the unreturned response message, it can be determined that the networked device is an inactive networked device, thereby realizing the identification of activated networked devices in the original device list. devices and non-activated networked devices.

S10122: If the access response information sent by the networked device is received within the preset time period, confirm that the networked device is an activated networked device;

Wherein, the time period is preset, and those skilled in the art can set the length of the time period according to specific design requirements, for example, the time period can be set to 1min, 2min or 5min, etc., as long as it can be effectively judged The activated networked device is enough, and will not be described here; in addition, after the activated networked device receives the access request, it will return a response message according to the access request, and the response message will be returned within a preset time period , according to the response message, it can be determined that the networked device is an activated networked device, that is, the activated networked device can be identified among all networked devices.

S10123: Determine an activated device list according to all activated networked devices.

After all activated networked devices are identified in the original device list, the activated device list can be obtained according to all activated networked devices, thereby effectively ensuring the accuracy of obtaining the activated device list.

Returning to Figure 1 again, after step S101, execute step S102: scan the adjacent devices of the activated networked devices according to the preset time period, and determine whether there is a new activated device among the adjacent devices; wherein, the adjacent devices are All devices within the adjacent network address within the preset range from the network address of the activated networked device;

For networked devices, due to various human and technical reasons, the addresses of activated networked devices always tend to gather in the address pool, that is, if there is a new activated device, the new activated device The address information of the networked device tends to be closer to the address information of the activated networked device, that is, the above-mentioned adjacent device. It should be noted that, in this embodiment, the specific distance between the address information of the adjacent device and the network address of the activated networked device The scope is not limited, and those skilled in the art can set according to specific design requirements, as long as the new activated device can be effectively determined, and details will not be repeated here.

In addition, in order to ensure the accuracy and reliability of obtaining the list of networked devices in wind farms, after obtaining the list of activated devices, the adjacent devices of the activated networked devices are scanned according to the preset time period to determine whether there are new activated devices in the adjacent devices. Activate the device, where it should be noted that the adjacent devices are all devices within the adjacent network address within the preset range from the network address of the activated networked device, for example: if the activated device list includes address information as 10.0.0.11 , 10.0.0.12, 10.0.0.13 corresponding to the activated networked device, at this time, you can set the adjacent device as the networked device corresponding to the address information 10.0.0.10 or 10.0.0.14, of course, you can also set the adjacent The device is set to include a networked device corresponding to address information 10.0.0.09 or 10.0.0.15.

After step S102, execute step S103: determine the networked device list of the wind farm according to the judgment result and the activated device list.

Specifically, the networked device list of the wind farm is determined according to the judgment result and the activated device list to specifically include:

S1031: If the judging result is that there is no new activated device among the adjacent devices, determine the activated device list as the networked device list;

There is no limit to the specific implementation of judging whether there is a new activated device. Those skilled in the art can set it according to specific design requirements. For example, an access request can be sent to an adjacent device. If the response information is returned, it can be confirmed that the adjacent device is a new activated device; if the adjacent device does not return a response within the preset time period, it can be confirmed that the adjacent device is not a new activated device; in this way, all If the judgment result is that there is no new activated device among the neighboring devices, the previously obtained list of activated devices can be used to determine the list of networked devices.

S1032: If the judging result is that there is a new activated device among the adjacent devices, update the activated device list according to the new activated device, and determine the updated activated device list as the networked device list.

After sending an access request to an adjacent device, if the adjacent device returns a response message within a preset time period, it can be confirmed that the adjacent device is a new activated device; at this time, there is a new activated device among the adjacent devices, in order To ensure the accuracy and reliability of networked device list acquisition, at this time, add a new activated device to the activated device list, and determine the updated activated device list as the networked device list, thereby ensuring the accuracy and reliability of the networked device list acquisition .

The method for obtaining the list of networked devices in wind farms provided in this embodiment first obtains the list of activated devices, and then scans the adjacent devices of the devices in the list of activated devices according to a preset time period to determine whether there is a new activated device. This effectively avoids the network storm caused by searching for devices in the entire network segment; and, when there is a new activated device, the list of networked devices can be determined according to the list of new activated devices and activated devices, ensuring that the list of networked devices Accurate and reliable acquisition; the method provided by the present invention ensures the network communication quality of the wind farm while avoiding network storms, improves the stability and reliability of the wind farm work, and effectively reflects the practicability of the method , Conducive to market promotion and application.

Fig. 4 is a schematic flowchart of a method for obtaining a list of networked equipment in wind farms provided by another embodiment of the present invention; The accuracy and reliability of the list, in this embodiment, after obtaining the activated device list storing all activated networked devices in the wind farm, the method is set to further include:

S201: Send an access request to the activated networked device in the activated device list according to a preset time period;

Wherein, the time period is preset, and those skilled in the art can set the length of the time period according to specific design requirements, for example, the time period can be set to 1h, 2h, 3h or 5h, etc.; The network-connected device sends the access request to determine whether the activated network-connected device is in a normal working state.

S202: If the response information sent by the activated networking device is not received within the preset time period, delete the activated networking device from the networking device list; or,

If the activated networked device does not return a response message within the preset time period after receiving the access request, it means that the activated networked device has a communication failure, and then it can be confirmed that the activated networked device is in an unactivated state , therefore, in order to ensure that the networked devices included in the networked device list are all activated networked devices, at this time, the activated networked devices that have not responded are deleted from the networked device list.

S203: If the response information sent by the activated networking device is received within the preset time period, keep the activated networking device in the networking device list.

If the activated networked device can return a response message within the preset time period after receiving the access request, it means that the activated networked device communicates normally, and then the activated networked device can be kept in the networked device list ; thereby effectively ensuring that the devices included in the list of networked devices are all in an activated state, thereby improving the accuracy and reliability of obtaining the list of networked devices.

It should be noted that scanning the adjacent devices of the activated networked device in step S102 and sending an access request to the activated networked device in step S201 may be implemented using an application layer protocol. Therefore, in the method provided by this embodiment, only the ARP broadcast in step S101 is at the data link layer. Therefore, the method as a whole needs to process very few underlying messages, and the data processing burden brought to the overall network is small, which can significantly improve the efficiency of searching and maintaining the list of networked devices.

For example, for a wind farm with 20,000 LAN addresses, it takes about five minutes to search for all devices by broadcasting in the prior art. However, by using the method in this embodiment, it only takes tens of milliseconds to search for all networked devices.

In order to understand the technical solution of this embodiment more clearly, the following specific application examples are given as examples:

Application example one:

1. A certain IP network segment is set, and the network configuration is 192.168.0.1/255.255.255.0. According to the network configuration, the available address pool size is 254;

2. After the initial scan, about 12 occupied IP addresses were obtained, which are located in 192.168.0.1-192.168.0.10 and 192.168.0.101-192.168.0.102 respectively;

3. Start to regularly scan and detect network changes according to the preset time period, and set the fragment length of the scan extension detection to 5 (the fragment length can be judged according to the size of the address pool, for example: divide 254 by 50, the result is about 5), At this time, the address to be scanned is 192.168.0.1-192.168.0.15, 192.168.0.96-192.168.0.107. You can see that the section to be scanned 192.168.0.96-192.168.0.107 is the above 192.168.0.101-192.168.0.102 The obtained occupied IP segments are increased by 5 before and after. As for the starting address of 192.168.0.1, since there were no more addresses before, 5 was not added before this.

4. After the first scan, 15 occupied IP addresses are detected, and this result will be used as the expansion base for the next round of scanning.

5. The second scan.

6. By repeating the scanning process, a list of activated devices in the network can be maintained all the time, that is, an accurate list of network devices can be obtained.

Application example two:

11. A certain IP network segment is set, and the network configuration is 192.168.1.1/255.255.0.0. According to the network configuration, the currently available address pool size is 65535;

12. After the initial scan, about 1000 centralized IP addresses were obtained, distributed around 192.168.0.0, and about 50 scattered around 192.168.128.1;

13. Since the current address pool is relatively large, the fragment length of the current scan extension detection is set to 50, which can ensure that if a new address appears and is allocated by skipping, there is a high probability that it can also be in the new scanning area. section covered. At this time, the total length of the first scanning section is on the order of about 2000.

14. Repeat the scanning process as in steps 4-6 in the first application example.

Compared with the global scanning in the prior art, the technical solution provided by the above-mentioned application embodiment 2 now has the number of addresses scanned each time changed from 65535 to about 2000, which is reduced by 30 times, which can greatly reduce the impact of scanning operations on the network. Occupation of resources increases the response time, thereby effectively improving the stability and reliability of the acquisition method, which is conducive to market promotion and application.
