Description

  The present invention relates to a time information transmitting / receiving device, a wristwatch, and a television receiver.

  Currently, in each country (for example, Germany, England, Switzerland, Japan, etc.), time data, that is, a long wave standard radio wave including a time code is transmitted. In Japan (Japan), long wave standard waves of 40 kHz and 60 kHz that are amplitude-modulated with a time code of a predetermined format are transmitted from two transmitting stations (Fukushima Prefecture and Saga Prefecture). This time code is transmitted in a frame of 60 seconds per cycle every time the minute digit of the correct time is updated, that is, every minute.

  In recent years, so-called radio timepieces have been put into practical use that receive standard radio waves including such time codes and thereby correct current time data. The radio timepiece receives a standard radio wave via a built-in antenna every predetermined time, corrects the current time by amplifying and modulating the time code.

  This type of radio timepiece is usually installed indoors, but it is often impossible to receive standard radio waves at the installation location, for example, in a steel frame house or basement. In order to eliminate restrictions on the location of the radio clock, a relay that receives standard radio waves, modulates the time code of the received standard radio waves with a predetermined carrier wave, and transmits it as a relay radio wave is provided. There has been proposed one that can reliably perform time correction by receiving radio waves with a radio clock (for example, see Patent Document 1).

  In the present embodiment according to the above configuration, as shown in FIG. 2, the standard radio wave including the time code 101 in which the remote control code is included in the spare bit 106 is transmitted from the radio tower 1 of the transmitting station every minute. Is transmitted in a frame of 60 seconds per cycle. On the other hand, the CPU 205 of the wristwatch type standard time repeater 2 executes processing as shown in the flowchart of FIG. 4 based on the program stored in the ROM 206. That is, a standard radio wave (a standard time code including a remote control code (time code 101)) transmitted from the radio tower 1 is received, the received standard time code is stored in the work area of the RAM 207, and a remote control code is stored. Is stored in the remote control code storage unit 218 (step S101). Next, based on the received standard radio wave (standard time code), the current time measured by the time measuring circuit unit 211 is corrected, and the corrected current time is displayed on the display unit 204 (step S102).

  Subsequently, it is determined whether or not all remote control codes received in a plurality of times have been received (step S103). That is, as described above, the remote control code is transmitted using the spare bits 106 of the time code 101, but the number of spare bits 106 is small. Therefore, for example, even when a remote control code for turning on the power of the television receiver 303 is transmitted, the spare bit 106 of the time code 101 transmitted at a time cannot include all of the remote control code. . Therefore, the remote control control code is divided into a plurality of times and sequentially included in the spare bits 106 of the time code 101 for transmission. For this reason, in step S103, it is determined whether or not all the remote control codes transmitted in a plurality of times have been received, and the processing from step S101 is repeated until all are received.

  When all the remote control codes transmitted in a plurality of times are received (step S103: YES), it is determined whether or not the manual transmission switch provided in the input unit 208 has been operated (step S104). If not operated, the processing from step S101 is repeated. Further, when the manual transmission switch is operated, the time information corresponding to the time code stored in the transmission time information storage unit 214 and the remote control code stored in the remote control code storage unit 218 are corresponded. Remote control information is transmitted to the outside (step S105). Here, the remote control information is information that can be transmitted by infrared transmission of the control content indicated by the remote control code, and can be controlled by receiving the home appliance (in this example, the television receiver 303). The CPU 205 generates remote control information from the remote control code and transmits it to the outside from the transmission unit 213 together with the time information.

  Therefore, as shown in FIG. 1, when the user U wearing the wristwatch-type standard time repeater 2 on his arm operates the manual transmission switch to turn on the television receiver 303, the power is turned on. Remote control information and time information are transmitted to the television receiver 303 by infrared rays. Then, the television receiver 303 receives this and turns on the power, and corrects the current time being measured based on the received time information. Therefore, it is possible to correct the current time measured by a device that does not have a radio clock function, such as the television receiver 303, without requiring a repeater. Further, other home appliances other than the television receiver 303 receive the time information and correct the current time measured based on the received time information. Therefore, the present time which all the household appliances in the house 3 time can be correct | amended correctly, without requiring a repeater.

  Note that in this embodiment, the case where the power of the television receiver 303 is turned on using the remote control code is described, but the power is turned on using a remote control unit such as the video deck 302 and the air conditioner 305.

  (Second Embodiment)

FIG. 5 is a flowchart showing a processing procedure of the CPU 205 in the second embodiment of the present invention. In this flowchart, the processes in steps S201 to S203 are the same as the processes in steps S101 to S103 in the first embodiment described above. In step S205, it is determined whether or not the value of the optical sensor included in the solar 215 is equal to or less than a preset value. Here, the case where the value of the optical sensor is equal to or less than a preset value is assumed to be a case where the user U who has gone out with the wristwatch type standard time relay 2 attached to his arm returns to the house 3. . Therefore, when the user returns home from the outside, the process proceeds from step S204 to step S205, and the time information and remote control information described above are transmitted to the outside (step S205). Therefore, all the household electrical appliances 301 to 307 existing in the house 3 can receive the time information and can correct the current time all at once. Further, for example, the television receiver 303, the video deck 302, the air conditioner 305, the Internet television 306, etc. can be turned on at the time of returning home by remote control information.

  (Third embodiment)

  FIG. 6 is a flowchart showing the processing procedure of the CPU 205 in the third embodiment of the present invention. That is, a standard radio wave (a standard time code (time code 101) including a video power ON code and a G code indicating a television program) transmitted from the radio tower 1 is received, and the received standard time code is stored in the work of the RAM 207. The video power ON code and the G code are stored in the remote control code storage unit 218 while being stored in the area (step S301). Next, based on the received standard radio wave (standard time code), the current time measured by the time measuring circuit unit 211 is corrected, and the corrected current time is displayed on the display unit 204 (step S302). Note that “G code” is a recording reservation code used in a simple video recording reservation system, and “G” is an acronym for Gemstar Development of the United States that developed it.

  Subsequently, it is determined whether or not the video power ON code and G code received in a plurality of times have been received (step S303), and the processing from step S301 is repeated until all are received. When all the remote control codes transmitted in a plurality of times are received (step S303: YES), it is determined whether or not the manual transmission switch provided in the input unit 208 has been operated (step S304). If not, the process from step S301 is repeated. When the manual transmission switch is operated, the time information corresponding to the time code stored in the transmission time information storage unit 214, the video power ON code stored in the remote control code storage unit 218, Remote control information corresponding to the G code is transmitted to the outside (step S305).

Therefore, as shown in FIG. 1, when the user U wearing the wristwatch-type standard time repeater 2 on his / her arm operates the manual transmission switch, remote control information, G code information, Time information is transmitted to the video deck 302 by infrared rays. Then, the video deck 302 receives this, turns on the power, reserves recording of the program with the received G code, and corrects the current time measured based on the time information. Therefore, it is possible to correct the current time measured by a device that does not have a radio clock function, such as the video deck 302, without requiring a repeater.
In this case, when the manual transmission switch is operated, remote control information for turning on the video deck 302, G code information, and time information may be transmitted to the video deck 302 at the same time. At least one of information, G code information, and time information may be transmitted. Further, remote control information, G code information, and time information may be appropriately combined and transmitted.

  (Fourth embodiment)

  FIG. 7 is a block diagram showing an internal configuration of the television receiver type standard time repeater 4 according to the fourth embodiment of the present invention. In this block diagram, 205 to 212 and 214 have the same configuration as 205 to 212 and 214 in the block diagram shown in FIG. The display unit 204 is disposed at the lower front part of the television receiver body. The transmission unit 413 outputs a control signal to the video deck 302 by wire. The digital television reception function unit 415 is composed of all circuits of a normal television receiver such as a circuit for displaying television images and a circuit for generating sound, and also has a ROM 416 and a RAM 417. The ROM 416 stores a program for controlling the digital television reception function unit 415, and the RAM 417 is used as a work area for controlling the digital television reception function unit 415 and stores a program code P. To do.

In the present embodiment according to the above configuration, as shown in FIG. 2, the standard radio wave including the time code 101 in which the remote control code is included in the spare bit 106 is transmitted from the radio tower 1 of the transmitting station every minute. The TV broadcast data (including the TV program code) including the transmitted time code 101 is transmitted to the TV receiver type standard time relay 4 disposed in a general home or the like. When the digital television reception function unit 415 receives the broadcast radio wave as the broadcast radio wave, the program content corresponding to the received television broadcast data is displayed on the display unit 204.
On the other hand, the CPU 205 of the television receiver type standard time repeater 4 described above executes processing as shown in the flowchart of FIG. 4 based on the program stored in the ROM 206.
That is, broadcast radio waves (including a remote control code, a television program code, and a standard time code (time code 101)) transmitted from the radio tower 1 are received, and the received standard time code is stored in the work area of the RAM 207. At the same time, the remote control code is stored in the remote control code storage unit 218, and the TV program code is stored in the RAM 7 (step S401). Next, based on the received standard radio wave (standard time code), the current time measured by the time measuring circuit unit 211 is corrected, and the corrected current time is displayed on the display unit 204, so that the digital television receiving function unit 415 is operated to display the program content corresponding to the received program code or television broadcast data on the display unit 204 (step S402).

  Subsequently, it is determined whether or not all remote control codes and program codes received in multiple times have been received (step S403). That is, as described above, the remote control code is transmitted using the spare bits 106 as the time code 101, but the number of spare bits 106 is small, and in this embodiment, the spare bits 106 are used. Then, the remote control control code and the program code are transmitted. Therefore, as will be described later, it is not possible to include all the remote control codes for turning on the video deck 302 in the spare bits 106 of the time code 101 transmitted at a time. Therefore, the remote control control code is divided into a plurality of times and sequentially included in the spare bits 106 of the time code 101 for transmission. For this reason, in step S403, it is determined whether or not all remote control codes transmitted in a plurality of times have been received, and the processing from step S401 is repeated until all are received.

  When all the remote control codes transmitted in a plurality of times are received (step S403: YES), it is determined whether or not a predetermined date / time or time has come (step S404). Here, the predetermined date and time and time are the date and time when the user turns on the video deck 302 and starts recording, for example, which is stored in the RAM 417 in advance by the user operating the input unit 408. When the predetermined date and time are reached, the time information corresponding to the time code stored in the transmission time information storage unit 214 and the remote control code stored in the remote control code storage unit 218 are added. Corresponding remote control information is transmitted to the outside (video deck 302) (step S405). Here, the remote control information in this embodiment is control information for turning on the power of the video deck 302 and starting the recording of the program displayed by the television receiver type standard time repeater 4. Accordingly, the video deck 302 is turned on by the processing in step S205, and the program corresponding to the received program code displayed on the television receiver type standard time repeater 4 at this time is recorded. Furthermore, the video deck 302 corrects the current time being measured based on the received time information. Therefore, it is possible to correct the current time measured by a device that does not have a radio clock function, such as the video deck 302, without requiring a repeater.
