In addition, the message response may be slow (exceeding the waiting time of the configured searching client), and even the response message is discarded, so that the number of the devices searched by the client is smaller than the actual number of the devices. This will cause inconsistency of the devices searched for multiple times on the final configuration management client, which will affect the configuration and management of the devices.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In the prior art, for device searching, a configuration management client sends a broadcast or multicast request every other time period, and displays a device returning a unicast response, that is, determines to search for a device returning a unicast response. However, in the prior art, only one broadcast or multicast request is sent and a response is waited for each time, if the time of the returned unicast response message exceeds the time of refreshing the configuration management client, or the response message is discarded due to network switch congestion, the number of devices searched each time is different, and the devices cannot be configured and managed.
According to the device searching method and device, the final searching result is determined by sending the two broadcast requests in one searching period and comparing the searching results of the two broadcast requests, so that one searching process is completed. And the search result is reserved after one search process, so that in the next search process, the broadcast request is sent once or twice again and is compared with the previously reserved search result to determine the search result, and the accuracy of the search result is improved.
In one embodiment, as shown in fig. 1, a device search method applied to a configuration management client is provided, where the device search method includes:
step S110, sending a first broadcast search request, receiving a response message returned by the equipment, recording the equipment which sends the response message in a first list, and setting a zone bit corresponding to the equipment as a first zone bit to show that the equipment is online.
The first time a broadcast search request is sent, it is to build a basic device list for comparison. If the configuration management client side already maintains the first list, after the broadcast search request is sent for the first time, the search result is placed in the first list.
In this embodiment, after the configuration management client sends the first broadcast search request, the device in the network receives the search request, and then responds, and sends a response packet through unicast. It is easily understood that the device on line can receive and respond to the broadcast search request, and the device off line cannot receive and respond to the broadcast search request.
The configuration management client in this embodiment may be a management server in a network or a terminal specifically used for searching for a display device, which is not limited in this application.
The configuration management client in the network may receive the response message sent by the device, so that the device may be recorded in the first list, where device information, such as an IP address, a device name, and the like, of all devices that send the response message is recorded in the first list. The device receives and responds to the information, and the information of the device itself is carried in the response message, which is a relatively mature technology.
In the first list, a flag bit is set for each device, and the flag bit is set to distinguish the device connection state after the last search of the device is finished, that is, the device connection state is an offline state or an online state. The flag bit may be a first flag bit or a second flag bit, for example, the first flag bit may be set to 1 to indicate the online state of the device, and the second flag bit may be set to 0 to indicate the offline state of the device, or may be replaced with other numbers or letters, which is not described herein again.
The first list is used as a basic device list for subsequent comparison, and the first list is continuously updated and maintained subsequently. After one searching process is finished and the next searching process is carried out, the first list is continuously adopted as a basic equipment list, wherein after the first broadcasting request in the next searching process, the responding equipment is added into the first list.
And step S120, sending a second broadcast search request, receiving a response message returned by the equipment, and recording the equipment which sends the response message in a second list.
As in step S110, this embodiment also sends a second broadcast search request, receives a response message returned by the device, and records the device that sent the response message in the second list. In contrast, the second list, which is only a temporary list, has no maintenance value after the search result is determined, and a flag bit does not need to be set for each device in the second list. A temporary list of target devices may be deleted after the comparison.
Step S130, comparing the apparatuses in the first list and the second list, if the target apparatus existing in the first list but not in the second list is found, adding the apparatus with the flag bit being the first flag bit into the first set, and adding the apparatus with the flag bit being the second flag bit into the second set, where the second flag bit indicates that the apparatus is offline.
In this step, after the search request is broadcast twice, the first list and the second list are compared to find out whether the devices recorded in the two lists are different, which may be the following three cases.
In the first case, there are devices in the second list that are not in the first list, that is, the second broadcast search finds a new device, which may be a device newly added to the network, or an offline device during the first broadcast search, or an unsearched device due to packet loss.
In the second case, there is no device in the first list in the second list, that is, when a device already in the network is searched for the second time, a new situation occurs, so that the device cannot be searched for, and the device may be offline or not searched for due to packet loss.
In the third case, the first list is the same as the devices in the second list.
For the third case, if after two search requests are broadcast, the devices in the first list and the second list are consistent, which indicates that no device is missed in the search, the first list is reserved as the final search result, and the search period is ended.
In this embodiment, for the first and second cases, it is necessary to add the unsearched devices caused by the two cases to a first list, which is used as a final search result, and display the devices on a search interface, and perform configuration and management.
For the first case, the present application compares the first list and the second list, and if a target device is found that is present in the second list but not present in the first list, the target device is added to the first list, and the flag bit corresponding to the target device is set as the first flag bit in the first list.
That is, if an apparatus a existing in the second list but not existing in the first list is found, the apparatus a is added to the first list and its flag position is set to 1. Therefore, the device A which is not searched in the first broadcast is added into the first list, and the unsearched result is more accurate.
For the second case, if the target device existing in the first list but not existing in the second list is found, and the flag bit corresponding to the target device is the first flag bit, adding it into the first set; and if the target device existing in the first list but not existing in the second list is found, and the zone bit corresponding to the target device is the second zone bit, adding the target device into the second set.
In the step, the devices in the first list but not in the second list are respectively added into different sets according to the zone bits of the devices, and then the state of the devices in the sets is confirmed.
Step S140, sending messages to the target equipment in the first set and/or the second set, and updating the state of the target equipment.
In the step, a message is sent to the target equipment in the first set to determine the online state of the target equipment, if the target equipment is online, the target equipment is removed from the first set, if the target equipment is offline, the target equipment is added into the second set, and the zone bit of the target equipment in the first list is set as the second zone bit to indicate that the equipment is offline.
Specifically, if there is found an apparatus B existing in the first list but not existing in the second list, and the flag bit corresponding to the apparatus B is the first flag bit, it is added to the first set. That is, the device B found by the first broadcast search is not found by the second broadcast search. The device B is not searched for in the second broadcast, which may be caused by offline of the device B, packet loss due to slow processing of the response message by the configuration management server, or failure to search for the device B due to congestion of the switch caused by a large number of response messages.
This embodiment sends a message to a target device in the first set, and updates the state of the target device, which specifically includes:
the configuration management server sends a message to the target equipment in the first set;
if the response message of the target equipment is received, judging that the target equipment is on line, and removing the target equipment from the first set;
if the response message of the target equipment is not received, continuing to send the message to the target equipment in the first set;
and when the response message of the target is not received for a plurality of times continuously, judging that the target equipment is off-line, adding the target equipment into the second set, and setting the zone bit of the target equipment in the first list as a second zone bit.
For example, device B is added to the first set, and devices C and D are added to the first set, the configuration management server sends a message to device B, C, D, and device B, C, D receives the message and then responds to the message, and sends a response message. At this time, because the number of devices in the first set is small, the message can be sent in a unicast manner, the switch is not congested due to the response message sent by the device in the first set, and the configuration management server can also process the response message in time, so that the device which is not searched before can be conveniently searched.
The configuration management server receives the response message from the device B, C, considers the devices B, C to be online, removes them from the first set, determines that the devices B, C were searched, and keeps them in the first list without change because the devices B, C are already in the first list and the flag is 1. This eliminates the situation where the device B, C is not searched for in the second search due to switch packet loss or slow processing.
If the network server does not receive the response message of the device D for a plurality of times, where the number of times may be set as a threshold, for example, 3 to 5 times, it is determined that the device D is offline. The reason for going offline may be the device powering down or the device being removed. The device D is added into the second set, the flag position of the device D is set to be 0 in the first list, and the device D is off-line.
In this embodiment, a message is also sent to the target device in the second set, and the state of the target device is updated. The method specifically comprises the following steps:
periodically sending messages to target equipment in the second set;
if receiving the response message of the target equipment, judging that the target equipment is on line, removing the target equipment from the second set, and setting the zone bit of the target equipment in the first list as a first zone bit;
and if the response message of the target equipment is not received, continuing to periodically send the message to the target equipment in the second set.
The configuration management server also sends a message to the target equipment in the second set, if the response message of the target equipment is received, the target equipment is judged to be on-line, the target equipment is removed from the second set, and the flag bit of the target equipment in the first list is set as the first flag bit. If the response message of the target is not received, the messages are continuously and periodically sent in the second set so as to update the state of the target equipment.
For example, if the device D is online in the second set, the device D receives the message sent by the configuration management server, responds, and sends a response message. After receiving the response message, the configuration management server determines that the device D is online, and sets the flag position of the device D in the first list to 1. And removes device D from the second set,
and if the response message of the device D can not be received all the time, the device D is considered to be continuously off-line, and the state of the device D is updated by periodically sending the message.
By the operation of this step, if there is a device in the second set, the checks are periodically made until there is no device in the second set. Therefore, the device D can be searched and added into the search result immediately after being online, and the accuracy of the search result is improved.
The method and the device perform dynamic maintenance on the offline equipment group (the second set), respond quickly after the offline equipment is online, and add the offline equipment group into the search result, so that the search result is more accurate.
By the two broadcasts, the obtained search result is placed in the first list, the device with the flag bit of 1 is online, and the device with the flag bit of 0 is offline. And when a searching process is restarted subsequently, the broadcasting searching request needs to be sent twice, the searched equipment is added into the first list after the first broadcasting searching, and the second list generated after the second broadcasting searching is compared with the first list, so that the searching result can be updated. The previous first list may also be discarded, and according to the method of the present application, the first broadcast search request is sent first to obtain the first list, and then the second broadcast search request is sent again to obtain the second list, and the first list and the second list are compared to obtain the search result.
In a specific embodiment, as shown in fig. 2, a device search method includes:
s201, sending a first broadcast search request, recording the equipment which sends the response message in an equipment table A (a first list) according to the received response message, and setting an equipment flag bit in the equipment table A to be 1.

S212, checking whether no response message is received for t times, if yes, executing step S213, otherwise, returning to step S208. The number of times t may be set to 3 to 5 times.
And S213, adding the rest members in the set C into the set D, setting the flag bits of the devices to be 0, and ending the search.
S214, adding the devices with the flag bit of 0 in the device table A but not in the device table B into the set D.
And S215, sending the message in the set D every two search periods.
The embodiment periodically sends the message to the device in the set D, the period can be flexibly set, and a period time can also be directly set, for example, the device searches once every 1-10 seconds, which is not limited in the present application.
