This source of information is hereinafter used as the closest analogue.

The disadvantage of the above technical solutions should be recognized as their insufficient accuracy of synchronization, especially for watches that are part of various independent synchronization systems, due to possible errors in setting the time of the central clock of each independent system.

The technical problem to which the developed design is aimed is to develop an improved time synchronization device.

The technical result obtained by the implementation of the developed design is to increase the accuracy of synchronization of watches included in various synchronization systems.

To achieve the specified technical result, it is proposed to use a time synchronization station of the developed design. The developed time synchronization station contains a central processor, the inputs of which are connected to the primary clock module and control panel, an indication module, a GLONASS / GPS radio signal receiver with a receiving antenna, and / or an alternative radio signal receiver, which are the reference frequency and time signals (ESCW), with the receiving antenna, as well as a power module connected to all power-consuming components of the station. The station may additionally contain a secondary clock control module connected to the power supply unit and the central processor, and / or a network synchronization module connected to the central processor, and / or an electronic scoreboard control module that generates information messages about the time and date, as well as the climatic parameters of the environment environment connected to the central processor, and / or uninterruptible power supply module, connected to the power supply module, and / or standard port / interface module, which allows for the transfer of July time scales for local consumers that support standard interfaces RS-232, and / or RS-422, and / or RS-485, and / or USB, and / or a load control module that allows you to control the operation of actuators by commands in manual mode or automatically in accordance with the algorithm stored in the main memory of the central processor, and / or an unauthorized access control module, and / or a network synchronization module supporting network synchronization protocols such as NTP (SNTP), and / or IRIG, and / or AFNOR, and / or PPS, and / or RTRLEEE 1588-2008, and / or DAYTIME , and / or TIME.

In the most preferred embodiment, the primary clock module is an electronic device or microcircuit that provides the formation of a time scale (second, minute, hour, day, month, year), the frequency of the reference signals of which are set by a highly stable quartz resonator (generator).

Typically, a control panel is a collection of controls, such as buttons, switches, switches, keyboards, as well as display elements, such as LEDs, small electric or gas-filled lamps.

The display module can be made in the form of a liquid crystal or LED indicator and an indicator control circuit.

The secondary clock control module is preferably a controller with an increased power output connected to the overcurrent protection circuit and providing time and date information in the required data format to the secondary clock.

The network synchronization module is usually a single-board computer that provides the formation of time and date data packets on client computers and network servers.

The electronic scoreboard control module is preferably based on a microprocessor and provides information on time, date, and climatic parameters in the required data format on electronic scoreboards.

The load control module is predominantly an electronic device that generates control signals for external actuators or warning devices (for example, sound or light) in manual or automatic mode in accordance with a schedule or algorithm of operation stored in the memory of the central processor.

The unauthorized access control module can be made in the form of a controller, the inputs of which are connected to sensors that provide broadcasting of notifications of unauthorized opening of the product body or changes in the settings and operation modes of the product, and non-volatile random access memory (internal (implemented on controller memory cells) or external, providing archiving of notifications (events).

However, it is possible to use these modules in other implementations.

Time synchronization station (CER) is intended for the formation, storage and display of the local time scale synchronized with the coordinated time scale (reference scale). The UTC or the Coordinated Time of the Russian Federation UTC (SU) can be taken as a reference scale.

The time synchronization station is configured to receive the following reference signals of frequency and time (ESCW):

- formed on the basis of the national coordinated time scale of the Russian Federation UTC (SU) and transmitted through the channels:

GLONASS satellite system;

radio stations of the state service of time, frequency and determination of the parameters of rotation of the Earth of the Russian Federation (GNSS);

television;

sound broadcasting networks;

- or / and signals generated on the basis of UTC and transmitted via the GPS satellite system (NAVSTAR).

The base of the station is the primary clock module and the central processor.

The primary clock module forms an internal CER time scale.

The central processor synchronizes the time scale with UTC (SU) or UTC according to the received ESCW and transmits information about the current time and date to the display module.

The control panel allows you to configure and control the functioning of the CERs.

The power module is designed to power the functional modules of the CER.

The block diagram of CERs is shown in the figure.

The secondary clock control module, designed to generate control pulses (minute or second) by the progress of the electromechanical clock, can be added to the composition of CERs; network synchronization module that allows you to implement the task of synchronizing computer networks using standard protocols, in particular, NTP or others. Using the network synchronization module allows you to achieve synchronization of processes and procedures implemented by software and hardware components in complex technical systems, for example, information, telecommunication and banking networks, automated control systems, etc.

Additionally or instead of the secondary clock control module, an electronic scoreboard control module can be introduced into the station, generating information messages about the time and date, as well as about the climatic parameters of the environment indoors or outdoors.

The introduction of an uninterruptible power supply module makes it possible to ensure the functioning of CERs in the event of a loss of centralized power supply during restoration work. The battery is used as an emergency power source.

The introduction of an additional module of standard ports / interfaces into CERs provides the broadcasting of the timeline to local consumers supporting standard RS-232, RS-422, RS-485 or USB interfaces. Using this module allows you to expand the list of paired devices of consumers, as well as to remotely monitor the functioning of CERs.

An additional introduction of the load control module to the CER allows you to control the operation of executive (electronic, electrical or electromechanical) devices by commands in manual mode or automatically in accordance with the schedule or algorithm stored in the main memory of the central processor.

An additional introduction to the CERs of the unauthorized access control module allows you to register relevant events and notify an authorized user.

In the basic embodiment, the time synchronization station operates as follows.

The primary clock module forms an internal time scale, the stability of which is ensured by a highly stable reference generator, and transfers it to the central processor.

The central processor corrects the time scale and transmits the time and date information to the display module.

Correction of the internal time scale occurs due to the reception, processing and analysis of ESCWs coming from GLONASS or GPS systems, specialized radio frequency broadcasting stations, television and sound broadcasting networks.

The reception and processing of ESCWs are performed by receiving antennas and GLONASS / GPS receivers or receiving antennas and receivers of alternative ESCWs, for example, signals from specialized RBU or RTZ radio stations, signals from Mayak or Radio of Russia, signals from the ORT television channel.

Correction of the internal scale ensures its high-precision synchronization with the coordinated time scale of the Russian Federation UTC (SU) or with the world coordinated time scale UTC.

Information about the current time and date is displayed by the display module.

The control panel allows you to configure and control the operating modes of the time synchronization station.

The power module provides a stable power supply to all components of the station.

The application of the developed station allows to increase the accuracy of synchronization of watches included in various synchronization systems.
