Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Embodiments of the present invention provide a method and device for sending and receiving repair packets, and a fault repair system, so as to realize fast direct connection between a faulty embedded device and a server, and further realize fast repair of the fault of the faulty embedded device.

The following first introduces a method for sending a repair package provided by an embodiment of the present invention, where the method for sending a repair package is based on a fault repair system.

As shown in Figure 1, the method may include the steps:

S101: Receive device information sent by at least one faulty embedded device, where the device information includes the original IP address of the faulty embedded device;

It can be understood that, after the embedded device is powered on, it detects its own failure through U-boot (Universal Boot Loader). If the main program is damaged, it will broadcast its own device information through U-boot regularly or irregularly. The server may receive device information broadcast by at least one faulty embedded device. Further, the server may display the received device information on the display interface. Among them, U-boot is a single-threaded loop program, which can be used as a boot program for embedded devices. The server can be a TFTP server and can provide repair packages for faulty embedded devices.

S102: Obtain a new IP address assigned to each faulty embedded device;

It should be noted that the server obtains a new IP address assigned to each faulty embedded device, wherein the new IP address may be reassigned by the user for each faulty embedded device. It can also be reassigned by the server for each faulty embedded device.

S103: Send a modification instruction to each faulty embedded device, so that each faulty embedded device obtains a new IP address for itself from the modification instruction, and uses the new IP address to directly connect with the server, wherein the modification instruction carries the new IP address assigned;

The server can send a modification instruction to each faulty embedded device through the existing technology, so that each faulty embedded device obtains a new IP address for itself from one or more modification instructions through U-boot, and modifies it through U-boot The original IP address of itself is the new IP address obtained for itself, and it is directly connected to the server through the new IP address.

S104: Receive repair requests sent by all faulty embedded devices;

S105: Send a repair package corresponding to the repair request to all the faulty embedded devices, so that all the faulty embedded devices complete the fault repair.

The repair request may carry information such as the device model of the corresponding faulty embedded device, so that the server can send a corresponding repair package to the faulty embedded device according to the device model of the faulty embedded device.

Applying the embodiment of the present invention, the server receives device information including the original IP address of the faulty embedded device sent by at least one faulty embedded device; obtains a new IP address allocated for each faulty embedded device; sends a modification instruction to each faulty embedded device Embedded devices, so that after each faulty embedded device obtains a new IP address for itself from the modification instruction, use the new IP address to directly connect with the server; receive repair requests sent by all faulty embedded devices; send and repair requests corresponding to The repair package is sent to all faulty embedded devices, so that all faulty embedded devices can complete the fault repair. It can be seen that the server can assign new IP addresses to the faulty embedded devices in the same network segment and different network segments, so that each faulty embedded device obtains a new IP address for itself from the modification instruction, and uses the new IP address to match with the new IP address. The server is directly connected, and there is no need to manually modify the IP address of the faulty embedded device one by one, which realizes the rapid direct connection between the faulty embedded device and the server, and further realizes the rapid repair of the fault of the faulty embedded device.

Moreover, the embodiment of the present invention can be directed to a faulty embedded device that exists in the same network segment, or can be directed to a faulty embedded device that exists in different network segments. By applying the embodiments of the present invention, there is only one server in different network segments, which is used to provide a repair package for the faulty embedded device, and it is not necessary to deploy a server in each network segment.

In a specific implementation manner, some faulty embedded devices are located in the same network segment as the server, and can be directly connected to the server without modifying the IP address. To save server resources, you can assign IP addresses only to faulty embedded devices that are on different network segments from the server. After the device information sent by the at least one faulty embedded device is received, the method for sending a repair package provided by the embodiment of the present invention may further include:

According to the device information, from the at least one faulty embedded device, determine all first faulty embedded devices, wherein the first faulty embedded device is a faulty embedded device whose original IP address is not in the same network segment as the server;

Said obtaining a new IP address assigned to each faulty embedded device, including:

Obtain a new IP address assigned to each first failed embedded device.

The server can, according to the original IP address of the faulty embedded device carried in the device information, and its own IP address, from the at least one faulty embedded device, determine all the first IP addresses that are not in the same network segment as itself. A fault embedded device, and the subsequent process. In addition, the user can view the device information sent by at least one faulty embedded device on the display interface of the server. It is understandable that the step of determining all the first faulty embedded devices that are not in the same network segment as the server can also be performed by the user. Input to the server after filtering on the interface.

In addition, when the faulty embedded device and the server are in the same network segment, the server can be directly connected to the faulty embedded device. Subsequently, the server may send a corresponding repair package to the faulty embedded device through the TFTP protocol, so that the faulty embedded device completes fault repair through U-boot. The device information may include information such as the device model of the faulty embedded device, so that the server can send a repair package matching the device model for the faulty embedded device.

In a specific implementation manner, the server does not know the path information sent to each faulty embedded device, and at this time, the modification instruction is sent in the form of broadcast. Since there are many other hosts in the network (including but not limited to non-faulty embedded devices), in order to reduce the processing burden of such hosts, the modification instruction can be sent in the form of multicast. In order to effectively reduce the burden of other hosts outside the "multicast" group on the network, because the data sent to the "multicast" group will not be transmitted to their drivers for processing, which avoids unnecessary waste of resources. The device information may also carry information on whether the corresponding faulty embedded device supports multicasting. Before the modification instruction is sent to each faulty embedded device, the method for sending a repair package provided by the embodiment of the present invention may further include: :

According to the device information, determine whether the corresponding faulty embedded device supports multicast;

When the corresponding faulty embedded device supports multicast, the sending the modification instruction to each faulty embedded device is: multicasting the modification instruction of the corresponding faulty embedded device;

When the corresponding faulty embedded device does not support multicast, the sending the modification instruction to each faulty embedded device is: broadcasting the modification instruction of the corresponding faulty embedded device.

For example, when the faulty embedded device includes five devices, A, B, C, D, and E, according to the device information, it can be known that A, B, and C support multicast, while D and E do not. Then, the modification instruction for A, the modification instruction for B, and the modification instruction for C are multicast respectively; the modification instruction for D and the modification instruction for E are broadcast respectively. For A, B, and C, they will receive the modification instruction for A, the modification instruction for B, the modification instruction for C, the modification instruction for D, and the modification instruction for E, and respectively select and carry the modification instruction for themselves. The new IP address modification command can be used. For D and E, they can only receive the modification instruction for D and the modification instruction for E, and respectively select the modification instruction carrying the new IP address for themselves.

In a specific implementation manner, the device information may further include the MAC address of the faulty embedded device;

The sending of modification instructions to each faulty embedded device includes:

Send a modification instruction carrying the MAC address of each faulty embedded device and the corresponding new IP address assigned to each faulty embedded device;

The new IP address for the self is: a new IP address for the MAC address of the self.

In order to better ensure that the server assigns a new IP address to each faulty embedded device, to ensure that each faulty embedded device determines a new IP address for itself, and avoids occupying the IP addresses of other embedded devices, the device information may also include The MAC address of the faulty embedded device. And the sent modification instruction carries the MAC address of each faulty embedded device and the correspondingly assigned new IP address, so that each faulty embedded device can filter out a new IP address for its own MAC address through U-boot.

Of course, it can be understood that the device information may also carry other information that can uniquely identify the faulty embedded device, and this type of information is not limited in this embodiment of the present invention.

In a specific implementation manner, the device information may further include the MAC address of the faulty embedded device;

Before receiving the repair requests sent by all faulty embedded devices, the method for sending a repair package provided by the embodiment of the present invention may further include:

receiving ARP information broadcast by the at least one faulty embedded device;

The corresponding relationship between the MAC address of the corresponding faulty embedded device carried in the ARP information and the new IP address is stored.

It can be understood that after the faulty embedded device modifies the IP address, other hosts in the network (including but not limited to the server and each switch device) do not store the corresponding relationship between the new IP address and the MAC address of the faulty embedded device. For example, the correspondence between the new IP address and the MAC address of the faulty embedded device is not stored in the ARP (Address Resolution Protocol, Address Resolution Protocol) table, and U-boot cannot respond to ARP requests of other hosts. In order to prevent the subsequent faulty embedded device from being unable to exchange information with other hosts, after the faulty embedded device modifies its own IP address, it can actively broadcast ARP information through U-boot, so that other hosts can increase the storage capacity of the faulty embedded device. The correspondence between the new IP address and the MAC address. Wherein, after storing the corresponding relationship, the server can send the corresponding repair package to the faulty embedded device, so that the faulty embedded device can complete the fault repair.

On the other hand, an embodiment of the present invention provides a method for receiving a repair package, wherein the method for receiving a repair package is based on a fault repair system. As shown in FIG. 2 , the method may include steps:

S201: Send device information to a server, where the device information includes the original IP address of the faulty embedded device;

S202: Receive the modification instruction sent by the server, wherein the modification instruction carries the assigned new IP address, and the new IP address is the address assigned by the server;

The modification instruction is sent by the server for each faulty embedded device. When there are multiple faulty embedded devices, the faulty embedded device receives the modification instruction through U-boot, and then filters out the modification instruction for itself through U-boot, and the modification instruction for itself carries the modification instruction assigned by the server. The new IP address for the faulty embedded device itself.

S203: Modify the original IP address of the faulty embedded device to the corresponding new IP address, so as to use the new IP address to directly connect with the server;

The faulty embedded device modifies the original IP address to the corresponding new IP address through U-boot, and directly connects to the server through the new IP address.

S204: send a repair request to the server;

S205: Receive a repair package corresponding to the repair request sent by the server, and complete fault repair.

Broadcast the address resolution protocol ARP information carrying the corresponding relationship between the MAC address of the faulty embedded device and the new IP address, so that after receiving the ARP information, the server stores the MAC address of the faulty embedded device and the new IP address. Correspondence.

It can be understood that after the faulty embedded device determines the new IP address for its own MAC address from the modification instruction through U-boot, it modifies the original IP address to the new IP address through U-boot, and actively broadcasts ARP information. So that other hosts including the server, after receiving the ARP information, store the corresponding relationship between the MAC address of the faulty embedded device and the new IP address, so that the faulty embedded device can conduct subsequent information exchanges with other hosts. . The server can send a repair package corresponding to the faulty embedded device to the faulty embedded device according to the corresponding relationship, so that the faulty embedded device can complete the fault repair. The device information broadcast by the faulty embedded device may also carry information such as the device model, so that the server sends a corresponding repair package to the faulty embedded device according to the device model.
