Fig. 2 is a schematic flowchart of a method for allocating an IP address of a device according to an embodiment of the present disclosure. The method of assigning device IP addresses of fig. 2 may be performed by the computer or server of fig. 1, or software on the computer or server (the software being a tool for testing smart helmets). As shown in fig. 2, the method for allocating an IP address of a device includes:
s201, acquiring a dynamic IP address network segment, wherein the dynamic IP address network segment comprises a plurality of dynamic IP fields;
s202, based on the dynamic IP address network segment, allocating the dynamic IP address to each device in a target device group by using a dynamic host configuration protocol, wherein the target device group comprises a plurality of devices;
s203, setting the dynamic IP address allocated to each device as a static IP to obtain a first static IP address of each device;

s206, the IP conflict detection processing is carried out on the second static IP addresses of all the devices in the target device group.
The embodiment of the disclosure is applied to an equipment management center, which runs on a server and is used for managing a plurality of pieces of equipment of a target equipment group, and allocates the dynamic IP address to each piece of equipment by using a dynamic host configuration protocol, or randomly generates a second static IP address for each piece of equipment from a static IP address pool when allocation of the dynamic IP address to each piece of equipment fails. DHCP (dynamic host configuration protocol) is a network protocol for a local area network. The method is characterized in that a server controls a range of IP addresses, and a client can automatically obtain the IP address and the subnet mask allocated by the server when logging in the server.
The disclosed embodiments are applied to the scene of a digital building (the building is provided with a plurality of devices such as monitoring devices and interphones), and the target device group can be all the devices in the digital building.
And setting the dynamic IP address allocated to each device as a static IP, namely, the dynamic IP address allocated to each device is not subject to the dynamic host configuration protocol, and fixing the dynamic IP address allocated to each device, thereby obtaining a first static IP address of each device.
And the IP conflict detection processing is used for detecting whether the first static IP addresses or the second static IP addresses of all the devices in the target device group have IP conflicts or not, and if the IP conflicts exist, redistributing the first static IP addresses or the second static IP addresses to the devices with the IP conflicts.
Because the dynamic IP address changes frequently, the dynamic IP address of the device changes every time the device connects to the network, which is not beneficial for monitoring the device, and the static IP address is a permanent address assigned to the device, and the static IP address of the device does not change every time the device connects to the network, which is not beneficial for monitoring the device.
According to the technical scheme provided by the embodiment of the disclosure, a dynamic IP address network segment is obtained, wherein the dynamic IP address network segment comprises a plurality of dynamic IP addresses; based on the dynamic IP address network segment, allocating the dynamic IP address to each device in a target device group by using a dynamic host configuration protocol, wherein the target device group comprises a plurality of devices; setting the dynamic IP address allocated to each device as a static IP to obtain a first static IP address of each device; performing IP collision detection processing on the first static IP addresses of all the devices in the target device group; if the dynamic IP address is failed to be allocated to each device in the target device group, randomly generating a second static IP address for each device in the target device group from a static IP address pool; and performing the IP conflict detection processing on the second static IP addresses of all the devices in the target device group, so that the technical means can solve the problem that the static IP addresses allocated to the devices in the digital building in the prior art can only be allocated manually, further improve the efficiency of allocating the static IP addresses in the digital building and reduce the cost.
Before step S201 is executed, that is, before a dynamic IP address network segment is obtained, where the dynamic IP address network segment includes a plurality of dynamic IP addresses, the method further includes: dividing the dynamic IP address network segment, the static IP address network segment and other IP address network segments by using an object program; and generating the static IP address pool based on a static IP address network segment, wherein the static IP address network segment comprises a plurality of second static IP addresses.
Before the target program is used to divide the dynamic IP address network segment, the static IP address network segment and other IP address network segments, some data that is set in advance, such as the type of the IP address, the network number and the subnet mask, should be acquired.
For example, the following steps are carried out: the type of the IP address is class B, the network number is 172.20, and the subnet mask is 255.255.0.0 (class B IP address, in the four segments of the IP address, the first two segments are network numbers, and the second two segments are device numbers). Then the range of IP addresses that can be partitioned is 172.20.0.1-172.20.254.254. 172.20.4.1-172.20.50.254 are dynamic IP address segments, 172.20.51.1-1272.20.254.254 are static IP address segments, and 172.20.0.1-172.20.3.254 are other IP address segments.
Optionally, the IP addresses in other IP address network segments may be used as a specific scenario, and the IP addresses in other IP address network segments may be configured according to the received IP address configuration instruction.
The target program can divide the dynamic IP address network segment, the static IP address network segment and other IP address network segments according to a preset proportion. Optionally, the static IP address pool may not be generated according to a static IP address network segment, and a second static IP address may be randomly generated for each device in the target device group directly from the static IP address network segment. The static IP address pool is generated according to the static IP address network segment because the randomness of the static IP address pool is better.
In step S204, performing IP collision detection processing on the first static IP addresses of all devices in the target device group, including: when IP conflict exists, based on the dynamic IP address network segment, reallocating the dynamic IP address to each first target device in a target device group by using a dynamic host configuration protocol, wherein the first target device is a device of which the first static IP address has IP conflict; setting the dynamic IP address reassigned to each first target device as the static IP to update the first static IP address of each first target device.
The number of devices with IP collisions should be equal to or greater than two. If at least two devices in the target device group have IP conflicts, that is, at least two devices in the target device group have the same IP address, it is impossible to distinguish the devices having the same IP address, and it is also impossible to separately manage and operate the devices having the same IP address. For example, two devices have the same IP address, and either both devices are controlled together or both devices are not controlled, and one of the devices cannot be controlled independently.
Reallocating the dynamic IP address for each first target device in the target device group by using a dynamic host configuration protocol; setting the dynamic IP address reassigned to each first target device as the static IP to update the first static IP address of each first target device. The dynamic IP address reassigned to each device is set as a static IP, that is, the dynamic IP address reassigned to each device is not subject to the dynamic host configuration protocol, and the dynamic IP address reassigned to each device is fixed, so that the first static IP address of each device is finally obtained.
In step S206, the performing the IP collision detection processing on the second static IP addresses of all the devices in the target device group includes: and when the IP conflict exists, randomly generating the second static IP address again for each second target device in the target device group from the static IP address pool, wherein the second target device is a device with the IP conflict existing in the second static IP address.
IP collision detection processing, comprising: acquiring a target log for distributing or generating IP addresses for all the devices in the target device group, wherein the IP addresses comprise: the first static IP address and the second static IP address; determining whether an IP conflict exists based on the target log.
The execution subject of the embodiment of the present disclosure is an equipment management center, and in the process of allocating or generating IP addresses for all the equipment in the target equipment group, the equipment management center may obtain a target log recording the process of generating IP addresses, and may determine whether an IP conflict exists according to the target log. For example, when the device management center allocates or generates an IP address for the 5 th device in the target device group, an "error on setting up interface 0:" appears in the target log, which indicates that the IP address of the 5 th device in the target device group and one of the 1 st to 4 th devices in the target device group are duplicated. By comparing the IP address of each device, a device that duplicates the IP address of the 5 th device can be specified.
IP collision detection processing, comprising: enabling all devices in the target device group to carry out interaction once, and acquiring all traffic in the interaction through traffic acquisition devices in the interaction, wherein each device can send out at least one traffic in the interaction; analyzing the collected flow to obtain an IP address and an MAC address of each device, wherein the IP address comprises: the first static IP address and the second static IP address; when one IP address corresponds to a plurality of MAC addresses, it is determined that an IP collision exists.
The method may include that all the devices in the target device group perform one-time interaction, and all the devices in the target device group send one message to a device management center, where one message is one flow. The flow collection equipment is arranged in the equipment management center, or the flow collection equipment provides flow collection service for the equipment management center. And analyzing each message to obtain the IP address and the MAC address carried by each message, and determining that IP conflict exists if one IP address corresponds to a plurality of MAC addresses. Since the IP address of each device is assigned by the device management center, the device management center knows the IP address of each device, and determines the device with the IP conflict when determining the IP address with the IP conflict.
In step S205, if the dynamic IP address fails to be allocated to each device in the target device group, randomly generating a second static IP address for each device in the target device group from a static IP address pool, including: when each device is not allocated or acquires the dynamic IP address within preset time, and it is determined that the allocation of the dynamic IP address for each device in the target device group fails, the second static IP address is randomly generated for each device in the target device group from the static IP address pool.
Optionally, when a specific device does not allocate or acquire the dynamic IP address within a preset time, the second static IP address is randomly generated for the specific device from the static IP address pool.
All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described in detail herein.
