Description

one

The invention relates to a technique for transmitting scales in time over telecommunication channels.

Radio clocks are known that contain a time signal receiver, a code converter with transmission keys, a time interval counter, and indicators in which the time is set using coded time signals lj | .

The disadvantage of this watch is the limited amount of reproducible information about time scales and conditions for their transmission.

The closest to the technical essence are the radio clock containing the receiver of time signals with selectors of information and synchronization signals connected to the inputs of the code converter, the outputs of which are connected to the first inputs of the code transfer keys, the second outputs of which are connected to the output of the receiver, the time keeping counter, the installation inputs of which are connected to the output of the code transfer keys, and the counting input with the receiving receiver, a device for indicating time values, the inputs of which are connected to

the outputs of the time keeping counter 2.

The disadvantage of this Radio Clock is that they receive and reproduce information about time values for ONE time scale only,

scales of the world coordinate of the example of the TUC or TUC + N (time). At the same time there is

10 a large number of consumers who use other time scales and who in these cases need additional information about the difference between the values transmitted and used

15 scales, as well as various kinds of additional information, related

, with the transmission of time scales, for example, information about the propagation conditions of radio waves, is necessary to automatically correct the delay values of the time signals, when they are pacnpot from the transmitter to the receiver, etc.

The purpose of the present invention is to improve the efficiency of receiving and reproducing additional information on time scales in radio clocks.

The goal is achieved by

In case of simultaneous indication of all additional information between the output of control device 9 and the inputs of keys 6, the additional information code includes a switch, for example, made in the form of a mechanically controlled switch. To identify the type of information indicated by the display device 8, additional indicators of the type of information are entered, the inputs of which are connected to the second outputs of the switch.

The proposed device uses a method for transmitting information about current time values, in which different types of additional information are transmitted sequentially through N cycles in the same group of full code format. In this case, the efficiency of using the time code in the radio clock is improved.

Clock Radio .work as follows. .
