Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Example one
As shown in fig. 1, the method for configuring an IP address of a communication device according to an embodiment of the present invention may include the following steps:
step 101: after detecting that the communication equipment is started, reading a first IP address from a storage module of the communication equipment;
step 102: establishing network connection between the communication equipment and the upper computer by utilizing the first IP address;
step 103: receiving an IP address resetting instruction sent by an upper computer;
step 104: according to the IP address resetting instruction, storing a second IP address carried by the IP address resetting instruction into the storage module, and covering a first IP address originally stored in the storage module;
step 105: after detecting that the communication equipment is restarted, reading a second IP address from the storage module;
step 106: the second IP address is configured as an IP address of the communication device.
According to the method for configuring the IP address of the communication equipment provided by the embodiment of the invention, the first IP address is stored in the storage module of the communication equipment, the network connection between the communication equipment and the upper computer can be established by utilizing the first IP address stored in the storage module when the communication equipment is started, the IP address resetting instruction sent by the upper computer can be used after the network connection is established, and the second IP address carried by the IP address resetting instruction is stored in the storage module to cover the first IP address, so that when the communication module is restarted, the second IP address can be read from the storage module, and the second IP address is configured as the IP address of the communication equipment. Therefore, after the communication equipment is restarted each time, the IP address is read from the storage module to establish communication connection with the upper computer, so that the IP address stored in the storage module can be updated according to the IP address resetting instruction sent by the upper computer, the IP address of the communication equipment is configured, and the use experience of a user is improved.
Example two
On the basis of the method for configuring the IP address of the communication device provided in the first embodiment, when the step 102 establishes the network connection between the communication device and the upper computer by using the first IP address, the method may specifically be implemented as follows:
a1: receiving an Address Resolution Protocol (ARP) request sent by an upper computer;
a2: acquiring a target IP address carried by the ARP request;
a3: judging whether the target IP address is the same as the first IP address or not, if so, executing A4, otherwise, ending the current process;
a4: and sending the first MAC address of the communication equipment to the upper computer so that the upper computer establishes a mapping relation between the first IP address and the first MAC address, and the upper computer can send information to the communication equipment according to the first MAC address.
After reading the first IP address from the storage module of the communication equipment, receiving an ARP request sent by the upper computer in a broadcast mode in real time, wherein the ARP request carries a target IP address of the communication equipment which needs to be communicated by the upper computer. And after receiving the ARP request, acquiring a target IP address carried by the ARP request, comparing the acquired target IP address with the read first IP address, and judging whether the target IP address is the same as the first IP address. If the target IP address is the same as the first IP address, the communication equipment which needs to be communicated by the upper computer is indicated to be current communication equipment, and the first MAC address of the current communication equipment is sent to the upper computer. And if the target IP address is different from the first IP address, the communication equipment which needs to be communicated by the upper computer is not the current communication equipment, and the received ARP request is discarded. After receiving the first MAC address, the upper computer creates a mapping relationship between the first MAC address and a target IP address (first IP address), and then the upper computer can obtain the first MAC address of the target communication device according to the mapping relationship, and can send information such as an IP address resetting instruction to the target communication device according to the first MAC address.
Whether the communication equipment required to be communicated by the upper computer is the current communication equipment or not can be determined by receiving the ARP request sent by the upper computer, and when the communication equipment required to be communicated by the upper computer is determined to be the current communication equipment, the MAC address of the current communication equipment is sent to the upper computer, so that the upper computer can send information to the current communication equipment according to the received MAC address, the upper computer can be ensured to be communicated with a plurality of communication equipment, and the use experience of a user is improved. In addition, the upper computer can establish the mapping relation between the MAC address and the target IP address after receiving the MAC address, so that when the upper computer needs to send information to the same communication equipment again, the upper computer can directly obtain the MAC address according to the mapping relation and send the information to the corresponding communication equipment, an ARP request does not need to be sent again, and the communication speed is improved.
EXAMPLE III
On the basis of the method for configuring the IP address of the communication device provided in the second embodiment, after determining whether the target IP address is the same as the first IP address, if it is determined that the target IP address is the same as the first IP address, the third IP address and the second MAC address of the upper computer may be obtained from the received ARP request, and a mapping relationship between the third IP address and the second MAC address is stored.
After the target IP address carried by the ARP request is determined to be the same as the first IP address, the IP address and the MAC address of the upper computer carried by the ARP request are further obtained, a mapping relation between the IP address and the MAC address of the upper computer is established and stored, if the communication equipment needs to send information to the upper computer, the MAC address of the upper computer can be obtained according to the mapping relation between the IP address and the MAC address of the upper computer, and then the information is sent to the upper computer according to the MAC address of the upper computer. Therefore, by storing the mapping relation between the IP address and the MAC address of the upper computer, the communication equipment can receive the information sent by the upper computer and also can send the information to the upper computer, so that the two-way communication between the upper computer and the communication equipment is realized, and the applicability of the IP address configuration method of the communication equipment is improved.
Example four
On the basis of the method for configuring an IP address of a communication device provided in any one of the first to third embodiments, after the second IP address is stored in the storage module, it may be further detected whether the second IP address and the first IP address are located in the same network segment, and the specific process may be implemented by:
b1: acquiring a first subnet mask of the first IP address and acquiring a second subnet mask of the second IP address;
b2: respectively converting the first IP address, the first subnet mask, the second IP address and the second subnet mask into corresponding binary sequences;
b3: performing binary AND operation on a binary sequence corresponding to the first IP address and a binary sequence corresponding to the first subnet mask to obtain a first verification sequence;
b4: performing binary AND operation on a binary sequence corresponding to the second IP address and a secondary system sequence corresponding to the second subnet mask to obtain a second verification sequence;
b5: judging whether the first verification sequence is the same as the second verification sequence, if so, executing B6, otherwise, ending the current flow;
b6: and sending prompt information for prompting that the first IP address and the second IP address are located in the same network segment to the upper computer.
For example, after the communication device is powered on, the first IP address read from the storage module is 211.95.165.24, the second IP address obtained from the IP address reset command is 211.95.164.78, the first subnet mask of the first IP address is 255.255.254.0, and the second subnet mask of the second IP address is 255.255.254.0. After the first IP address, the second IP address, the first subnet mask and the second subnet mask are respectively converted into the second-level system sequence, the corresponding relation between the second-level system sequence and the first-level IP address is as follows:
first IP address: 11010011010111111010010100011000, respectively;
first subnet mask: 111111111111111111111111000000000, respectively;
second IP address: 11010011010111111010010001001110, respectively;
second subnet mask: 111111111111111111111111000000000.
the binary and operation is performed on the binary sequence corresponding to the first IP address and the first subnet mask to obtain a first verification sequence 11010011010111111010010000000000. And performing binary and operation on the binary sequence corresponding to the second IP address and the second subnet mask to obtain a second verification sequence 11010011010111111010010000000000.
And because the first verification sequence is the same as the second verification sequence, sending simultaneous information to the upper computer to prompt that the first IP address and the second IP address belong to the same network segment.
Under normal conditions, the reason that the IP addresses of the communication equipment are reset is that the IP addresses of the upper computer and the communication equipment are not in the same network segment, if the second IP address obtained from the IP address resetting instruction and the first IP address stored in the storage module are in the same network segment, the network segment where the communication equipment is located cannot be changed by replacing the first IP address with the second IP address, and at the moment, the IP address resetting instruction may be an illegal instruction and is intended to perform behaviors such as illegally reading information stored in the communication equipment. And after the second IP address and the first IP address are determined to be in the same network segment, sending prompt information to the upper computer to prompt the upper computer that the second IP address and the first IP address are in the same network segment. Therefore, if the IP address resetting instruction received by the communication equipment is not sent by the upper computer or is sent by the upper computer in a clamped state, a user of the upper computer can find and adopt corresponding measures in time, and the safety of communication between the upper computer and the communication equipment is improved.
It should be noted that, when performing binary and operation on the first IP address and the first subnet mask, and the second IP address and the second subnet mask, for two binary numbers of the two binary numbers, if both the two binary numbers are 1, the and operation result is 1, and if one of the two binary numbers is 0, the and operation result is 0.

For example, the target IP address obtained by the ARP handshake module from the ARP request is 211.95.165.24, and step 504 is performed because the target IP address is the same as the first IP address.
Step 504: and the ARP handshake module sends the MAC address of the communication equipment to the upper computer, and establishes network connection between the communication equipment and the upper computer.
In the embodiment of the invention, the ARP handshake module sends the MAC address of the communication equipment to the upper computer after determining that the target IP address is the same as the first IP address. The upper computer establishes a mapping relation between the MAC address and the target IP address after receiving the MAC address sent by the communication equipment, and can determine the MAC address of the communication equipment according to the mapping relation when the upper computer needs to send information to the communication equipment corresponding to the target IP address, and then sends the information to the communication equipment according to the MAC address.
Step 505: the ARP handshake module acquires the IP address and the MAC address of the upper computer and stores the mapping relation between the IP address and the MAC address of the upper computer.
In the embodiment of the invention, after the ARP handshake module sends the first IP address to the upper computer, the IP address and the MAC address of the upper computer can be obtained from the received ARP request, and after the mapping relation between the IP address and the MAC address of the upper computer is established, the mapping relation is stored in the local of the communication equipment. And then, the data sending module of the communication equipment can determine the MAC address of the upper computer according to the mapping relation and further send data to the upper computer according to the MAC address.
Step 506: and receiving an IP address resetting instruction sent by the upper computer, and acquiring a second IP address from the IP address resetting instruction.
In the embodiment of the invention, after the network connection between the upper computer and the communication equipment is established by using the first IP address, the IP address resetting instruction sent by the upper computer is received, and after the received IP address resetting instruction is determined to be specific to the current communication equipment, the IP configuration module analyzes the IP address resetting instruction to obtain the second IP address carried by the IP address resetting instruction.
For example, the second IP address obtained from the IP address reset instruction is 211.95.164.78.
Step 507: and storing the second IP address into the storage module, and covering the first IP address originally stored in the storage module.
In the embodiment of the present invention, after acquiring the second IP address, the IP configuration module stores the second IP address in the storage module, and covers the first IP address originally stored in the storage module. In addition, the IP configuration module can detect whether the second IP address and the first IP address are located in the same network segment, and prompt the upper computer of prompt information that the first IP address and the second IP address are located in the same network segment if the second IP address and the first IP address are located in the same network segment.
Step 508: and after the communication equipment communicates, reading the second IP address from the storage module.
In the embodiment of the invention, after the communication equipment is reset or restarted, the IP configuration module reads the second IP address from the storage module.
For example, after the communication device is restarted, the second IP address 211.95.164.78 is read from the memory module of the communication device.
Step 509: and setting the second IP address as the IP address of the communication equipment, and establishing network connection between the communication equipment and the upper computer.
In this embodiment of the present invention, after the IP configuration module reads the second IP address from the storage module, the second IP address is used to establish the network connection between the communication device and the upper computer, and the specific process is similar to the process of establishing the network connection between the communication device and the upper computer by using the first IP address, which may refer to steps 502 to 504, and is not described herein again.
In summary, according to the method for configuring an IP address of a communication device and the communication device provided in the embodiments of the present invention, a storage module of the communication device stores a first IP address, when the communication device is started, a network connection between the communication device and an upper computer can be established by using the first IP address stored in the storage module, after the network connection is established, an IP address resetting instruction sent by the upper computer can be used, and a second IP address carried by the IP address resetting instruction is stored in the storage module to cover the first IP address, so that when the communication module is restarted, the second IP address can be read from the storage module, and the second IP address is configured as the IP address of the communication device. Therefore, after the communication equipment is restarted each time, the IP address is read from the storage module to establish communication connection with the upper computer, so that the IP address stored in the storage module can be updated according to the IP address resetting instruction sent by the upper computer, the IP address of the communication equipment is configured, and the use experience of a user is improved.
