Description

A method for synchronizing the autonomous operation of digital devices

APPLICATION AREA

The invention relates to network technologies, in particular to a method for synchronizing the autonomous operation of digital devices in modes connected to the Internet and disconnected from the network in the global INTERNET network, connected to the Zig Bee upper-level network protocol specification, to an open wireless local network protocol with a mesh topology Fred, to the production specification of Bluetooth wireless personal networks, to the wireless local area network technology with Wi-Fi devices, or to the wireless high-speed data transmission standard for mobile phones and other LTE terminals and defines how to maintain digital devices in a single network when connecting and disconnecting the INTERNET network and in local networks connected to the Zig Bee Upper Layer Network Protocol Specification, to Fred's Open Mesh Wireless LAN Protocol, to the Bluetooth Wireless Personal Area Networks product specification, to the mouth-to-mouth wireless LAN technology by Wi-Fi devices, or according to the standard of wireless high-speed data transmission for mobile phones and other LTE terminals.

LEVEL OF TECHNOLOGY

Known patent 2342692 TIME REFERENCES FOR MULTIMEDIA OBJECTS. Describes how to associate time with media objects that define temporary references for media objects. These solutions are aimed at streamlining work with files and synchronize playback only within a separate document, and do not control digital devices in any way.

There is a patent 2675192 INFORMATION PROCESSING DEVICE, METHOD AND PROGRAM Describing information processing method capable of synchronizing multiple pieces of content received through different routes. The method described in the patent synchronizes a plurality of fragments only within a multimedia file.

The closest patent is 2620716 SYNCHRONIZING THE PLAYBACK OF MULTIMEDIA CONTENT IN GROUP VIEW describing a method and a device for synchronizing the playback of multimedia content between a group of users, each of them receiving a multimedia content on the web at approximately the same time. For synchronous playback, the synchronizer can make adjustments to the playback modes of one or more client device platforms within a group viewing the same multimedia content. If the platform of the client device lags behind the group, the playback mode of this platform can be changed to the fast playback mode. If the platform of the client device is ahead of the group, the playback mode of this platform can be changed to slow playback mode. The disadvantages of this solution are the complexity of processing a large number of parameters in a short time, the need for continuous connection to the INTERNET network of all devices, the impossibility of working in local networks Bluetooth, NSF, etc. In addition, the need to receive multimedia content over the network at approximately the same time is declared, which excludes its advance reception by subscribers by choosing the most convenient time and the necessary requirements for the parameters of network connections.

DISCLOSURE OF THE INVENTION

Synchronous operation of digital devices is of great interest as a way of communication and as an opportunity to combine efforts to achieve security. A scenario executed by a group of digital devices will allow observers to get more pleasure, increase the space of influence, visibility and strength of influence compared to a single one.

The present invention establishes a single execution of a given scenario of digital devices operation in the case of connecting a subscriber to a group later than the start of execution, and in cases of suspension of the digital device operation. Synchronous operation of digital devices guarantees the same light and sound operation of the device, vibration and display of multimedia content at any time, with the same start time. Variants of the present invention enhance communication capabilities and increase the reliability of achieving security.

The technical result consists in the simultaneous execution of any arsenal of actions by digital devices (light, sound, vibration alarms, photographing, video recording, video playback, playback of music, voice files and other actions for various purposes).

The specified technical result is achieved due to the fact that the method of synchronizing the autonomous operation of digital devices in modes connected to the Internet and disconnected from the network includes launching the application on digital devices connected to the Zig upper-level network protocol specification. Bee, to Fred's open mesh wireless LAN protocol, to Bluetooth wireless personal area networks (WLAN) technology, to Wi-Fi devices, or wireless high-speed data transmission standard for mobile phones and other LTE terminals, scanning, communication with subscribers, forming a subnet, creating a subnet notification by the application about viewing with a summary of the material, data and time, and the notification contains a hidden identification request, which can only be answered by a device that has an installed and running application, while the subscriber automatically communicates with the local administrator or network a repeater in the case of a preinstalled application and receives a general broadcast file, other digital devices receive a link to install the application, while significant subnet signals are transmitted and stored on the server and in the application, the device by the local administrator the counter, and in the counter of the main screen of the application the number of subscribers is indicated and in each application a command is generated to play with a time skip, the software module for calculating the skip of the application is tied to a single application time and calculates the duration of the skip between the following events: general broadcast) and an acceptance signal (readiness for playback) by any subsequent subscriber.

Thus, digital devices can simultaneously perform any arsenal of actions (light, sound, vibration alarms, photography, video recording, video playback, playback of music, voice files and other actions for various purposes).

BLUEPRINTS.

The essence of the proposed method is illustrated by the diagram shown in FIG. one.

DESCRIPTION OF THE IMPLEMENTATION OF THE METHOD

Initial state: on the digital device of the local administrator (hereinafter referred to as LA), the application is running, Bluetooth, Wi-Fi and LTE are on.

The aircraft in the application generates an invitation (invite) for other network participants to view. An invite reflects a brief content / topic of the material in the form of text, video intro, audio intro, its planned start of playback (general pseudo broadcast time). This invite is transmitted via Bluetooth channels to other digital devices located in the zone.

Let's consider the use of the BT v.4 protocol. This protocol is supported by most devices running Android and iOS OS. Characteristics: data transfer rate - up to 1 mb / s, connection speed - less than 1 sec., Practical communication range - up to 20 m., High noise immunity.

The set of functions is called a profile. We highlight when using the BT v.4 protocol. the following main profiles:

- DIP - device identification profile

- BIP - for transferring images

- A2DP - for audio streaming

- OPP - basic for sending files

- VDP - mpeg-4 streaming video profile

To send an invite, we form and send a command to the Bluetooth module of a digital device to search for the nearest Bluetooth devices (scanning). An invite contains a hidden identification request, which can only be answered by a device that has an installed and running application.

A nearby device that does not have an installed and running application receives a standard request to accept a text and / or text-graphic file of the minimum size. Such a file contains brief information and a direction (link) to install the application from the market.

A subscriber joining an aircraft or a network repeater in the case of a preinstalled application receives a general broadcast file, or a link to install the application (installs the application and then in general mode). The exchange of signals when sending a file of the general broadcast forms a subnet and in the form of log files is transmitted and stored on the server or the aircraft application, and the number of subscribers is indicated in the counter of the main screen of the application. Having the settings for automatic reception of files via Bluetooth on the screen of the receiving digital device, an invite is displayed. In the absence of automatic settings, the receiver manually selects whether to accept the file or refuse to receive it.

In the case of scanning and detecting a digital device with an installed and running application, the latter sends its own application ID to the aircraft application. The connection is established automatically. The transmitted identifier contains a unique application number in the format [Тххххххх] [pass-address] [date and time]. The identifier received by the application in the digital device of the aircraft is transmitted to the server in xml format. On the server side, this event is recorded to the corresponding library. The record line has the following form: [date and time] [Tuuuuuuu] [Тххххххх] [mac-address] [send], where Tuuuuuuu - unique aircraft application number, Тххххххх - application number from which the response was received.

The subscriber who agrees to accept the file from the aircraft proceeds to receive the file, at the end of which the Bluetooth session is terminated, a signal is sent to the server about the completion of the file reception.

The number of simultaneous independent BT Bluetooth sessions is up to 5. When applications are running on all digital devices as a repeater, requests for BT Bluetooth connections are sent based on the maximum power (amplitude) of the radio signal. See fig 1.

To prevent the sending of invites, files to the same application, before sending, a comparison is made according to a bunch of 2 parameters: the unique application number and the mac-address of the device, providing a minimum level of protection for BT Bluetooth sessions. The shared broadcast file to be sent is in the memory of the aircraft's smartphone.

The connected digital devices automatically transmit the invitation of the aircraft (and hereinafter the file of the general air) via BT Bluetooth and other channels to the following subscribers, they act as a network repeater.

The log file of the 1st subscriber who received the general broadcast file contains a significant information bit (readiness for playback, hereinafter the main bit), which is considered the countdown time of the start of playback of the general broadcast file.

In the application of all subscribers, which received the general broadcast file, a command is formed to play with a time gap. The software module for calculating the time gap included in the application is tied to the time of the application (server) and calculates the duration of the gap between the following events: the completion of the file acceptance by the 1st subscriber (the main bit of the general broadcast file) and the bit of the log file of the completion of the acceptance (readiness for playback) by any by the next subscriber, this data is transmitted to the north.

The file of the general broadcast is formed by the application by attaching 100 seconds (or other time) of the buffer broadcast of the countdown before the start of playback on the main screen and the file from the memory of the aircraft device.

Server operation revises the continuation of the general broadcast file distribution in case of non-receipt of the bit of the acceptance completion log file (ready for playback) by any subsequent subscriber before the general broadcast end time.

Monitoring and data processing of network log files allows you to obtain information characterizing the composition of the subnetwork (the number of digital devices, connection of new subscribers, disconnection of digital devices, location, technical data of devices). Data processing of Bluetooth and NSF sessions, location modules determination of coordinates of GSM, GPS, GLONASS, Galileo systems, satellite communication module, biometric sensors, battery, wireless charging means allows you to create and control important security lines for digital devices, their operators, territories, objects, industries, aircraft and ships, trains, cars, shopping centers, rallies, concerts and public events.

Saving and processing log files of data exchange in local networks allows solving problems of positioning digital devices inside buildings, and in the absence of GSM, GPS, GLONASS, Galileo networks.

The technical result of saving and processing log files of data exchange in local networks is additional protection of any transactions made using a digital device token (token is a set of data used for payment). NSF log files of token exchange with the merchant's POS terminal, log files of a digital device token transaction on the INTERNET, stored in the application and the server, provide an additional line of protection.

Light, sound and vibration alarms of a digital device, randomly generated, unique for each general broadcast, creates a defense line easily controlled by aircraft, subscribers and security services of facilities, industries, aircraft and ships, trains, cars, shopping centers, rallies, concerts and public events ...

Processing and analysis of network log files (number of devices, connection of new devices, disconnection of devices, location, technical data of devices) and notification of the group about changes creates a line of protection against unauthorized access, signaling the loss of a device, warnings of the possibility of disconnection, the need to recharge, etc. This opportunity is relevant when registering passenger devices on flights, routes, temporary stops and organizing access to private areas.

Setting the rules for the general broadcast creates the ability to control the activity of each digital device in the group, immediately notifies the group about violation of the rules, it is relevant on air flights (prohibition of connecting to LTE, GSM networks), meetings and events of the declared general security of facilities and industries
