Detailed Description
In order to facilitate the explanation of the technical solution of the cross-device communication method in networking according to the present invention, the following will first take audio processor networking as an example to introduce some relevant contents.
A complete multi-processor cross-device communication system is composed of a plurality of audio processor devices (generally up to 64 devices) in the same local area network, a plurality of systems can exist in one local area network, whether the systems exist in the same system or not is determined by the system name of the device, and after the devices form the system, unified management of the devices can be achieved, such as calling preset and triggering events.
In practical applications, in order to achieve the purpose of forming a system by a device ad hoc network, it is necessary for one device in the system to take a role as a server to manage and schedule other devices. In one embodiment of the cross-device communication method in networking of the application, the server can be generated by adopting two modes of device self-election and manual designation. The server is responsible for managing other non-server devices, and the server is only an application program and does not depend on hardware. In one system, all devices communicate directly with the server, and there is no direct communication between the devices. The devices adopt multicast communication to race for the server and notify the server on line, a TCP (Transmission Control Protocol) link is established between the server and each device to carry out communication, a strategy that the devices are actively connected with the server is adopted, a device list is required to be maintained in the server, and the list contains information of all the devices. A device may change state during operation, such as from a server to a client and from a client to a server. When no server exists in the system, equipment in the system elects one piece of equipment as the server through multicast communication, the arbitration basis is the IP address of the equipment, and an IP larger person preferentially becomes the server; when one of the servers is appointed, other devices are all used as clients, and server election is not performed any more; when the server is disconnected or fails, the client side is overtime and re-selects the server; once the device state machine sends the change, the corresponding configuration file will be updated at the same time, and the state at the next device power-on depends on the state in the configuration file.
As shown in fig. 1, a method of cross-device communication in a network, comprising the steps of:
s200: and reading the configuration file, and self-checking whether the configuration file is the server equipment in the networking.
The configuration files are used for configuring each device in the networking, each device is provided with a corresponding configuration file, and the device reads the configuration files after being electrified. The networking comprises a plurality of devices, when the devices are not configured, communication is not established between the devices, and the devices belong to a peer-to-peer relationship, namely, no certain device is used as a server to manage other devices, and each device reads a configuration file of the device and detects whether the device is configured as a server device. Specifically, the configuration file in the device may be preset and stored in the device; the device can be directly led in from the outside and read after receiving; it is also possible that the user manually modifies the generation of data stored in the device in advance. When the read configuration file carries a server identifier, the device reading the configuration file is used as a server device in the networking of this time, for example, A, B, C, D total 4 devices exist in the current networking, 4 devices respectively read a, b, c and d configuration files corresponding to the 4 devices, and the 4 devices respectively self-check whether the 4 devices are the server devices in the networking.
S400: and when the device is a non-server device, sending the multicast communication data packet to other devices in the network, wherein the multicast communication data packet carries the IP address of the device.
Multicast communication refers to the implementation of a point-to-multipoint network connection between a sender and each recipient. And when the equipment self-checking result is that the equipment is non-server equipment, sending a data packet to other equipment in the network in a multicast communication mode, wherein the data packet carries the IP address of the equipment. Taking the device a as an example, when the self-test of the device a is a non-server device, the device a sends a multicast communication packet a to B, C, D devices in the networking, where the multicast communication packet a carries the IP address of the device a itself.
S600: and respectively receiving the multicast communication data packets sent by other devices.
The devices which are self-checked as non-server devices in the networking execute step S400 to transmit multicast communication packets to other devices, and also receive multicast communication packets transmitted by other devices, respectively. Continuing taking the device a as an example, the device a receives a multicast communication data packet 1 from the device B, a multicast communication data packet 2 from the device C, and multicast communication data 3 from the device D, where the multicast communication data packet 1 carries an IP address of the device B, the multicast communication data packet 3 carries an IP address of the device C, and the multicast communication data packet 3 carries an IP address of the device D.
S800: if the IP address of the user is larger than the IP address carried in any one of the received multicast data packets, communication with other equipment is established, the configuration file is updated, and the updated configuration file carries the server equipment identifier.
After receiving multicast communication data packets sent by other devices, the device compares the IP address carried in the multicast communication data packet sent by the other devices with the IP address of the device, when the IP address of the device is larger than the IP address carried in any one of the received multicast data packets, the device modifies the device into server equipment to establish communication with the other devices, and writes a server equipment identifier into a configuration file to update the configuration file. Specifically, after receiving the multicast communication data packet 1 from the device B, the multicast communication data packet 2 from the device C, and the multicast communication data 3 from the device D, the device a compares its own IP with the IP address of the device B carried in the multicast communication data packet 1, the IP address of the device C carried in the multicast communication data packet 3, and the IP address of the device D carried in the multicast communication data packet 3, and when the comparison result is that the IP address of the device a is the maximum, the device a establishes communication with other devices (B, C, D devices), the device a switches to the server device, updates its own configuration file, and the updated configuration file carries the identifier of the server device. Briefly, the above process may be understood as a process of arbitrating server devices in a networking based on the size of an IP address, each device in the networking is processed in the same manner, and when a certain device finds that its own IP address is the largest by comparison, it switches itself to be the server device, establishes communication with other devices, and realizes coordination management of other devices, and communicates with an external upper computer.
The cross-device communication method in the networking of the application reads the configuration file, self-checks whether the device is the server device in the networking, sends the multicast communication data packet to other devices in the networking when the device is the non-server device, respectively receives the multicast communication data packet sent by other devices, if the IP address of the device is larger than the IP addresses of other devices, the device is the server device, establishes communication with other devices, and updates the configuration file. In the whole process, the IP addresses of all devices in the networking are compared in a multicast communication mode, the device with the largest IP address is selected to be changed into the server device based on the size of the IP addresses, the server device is communicated with all the devices, and good cross-device communication in the networking is achieved.

s320: when the server equipment is used, a data acquisition request sent by an external upper computer is received;
s340: and pushing the collected data of other equipment to an external upper computer.
When the equipment self-checking identification is server equipment, the equipment self-checking identification communicates with an external upper computer, receives a data acquisition request sent by the external upper computer, sends a data feedback message to other equipment, the other equipment feeds back self data to the server equipment, the server equipment completes data acquisition of the other equipment and pushes the acquired other equipment data to the external upper computer, and management of the server equipment on other equipment (non-server equipment) in a networking is achieved.
In one embodiment, the method of networked cross-device communication further comprises:
and when the server equipment exists in the networking, rejecting to respond to the multicast data packet sent by other equipment.
When the server equipment exists in the networking, the server equipment does not need to be determined based on multicast communication and an IP address size arbitration mode, and the server equipment responds to multicast data packets sent by other equipment. Specifically, when receiving an access message sent by a server device, a device may recognize that the server device exists in the current network, and at this time, reject to respond to a multicast data packet sent by another device, where the reject to respond may specifically be reject to receive, or directly discard after receiving the multicast data packet.
In one embodiment, when there is a server device in the networking, the step of rejecting the multicast packet sent by the other device includes:
and when receiving an access message sent by the server equipment in the networking, establishing communication connection with the server equipment and stopping sending the multicast communication data packet.

In one embodiment, the method of networked cross-device communication further comprises:
and if the connection with the server equipment in the networking is overtime, returning to the step of sending the multicast communication data packet to other equipment in the networking.

As shown in fig. 2, in one embodiment, step S200 includes:
s220: reading a configuration file;
s240: and judging whether the configuration file carries the server equipment identifier or not.
If the configuration file carries the server equipment identifier, the equipment is switched into the server equipment after reading the configuration file; and if the configuration file does not carry the server equipment identifier, the equipment confirms that the equipment is non-server equipment after reading the configuration file, and enters the next step of processing.
As shown in fig. 2, in one embodiment, step S200 further includes:
s100: and receiving the configuration file uploaded by the user.
The device may receive a configuration file uploaded by a user, where the configuration file may be generated after the user manually modifies an initial configuration file, for example, the user manually modifies the configuration file of the device a, and writes a server device identifier in the configuration file of the device a, so that the device a is used as a server device in networking after receiving and reading the configuration file, that is, a process of manually setting the server device in networking is implemented.
