Description

  The present invention relates to a time recording device such as a time recorder and a time stamp, and more particularly to a time recording device having a function of correcting the time counted by itself based on external time information such as a standard radio wave.

  Currently, it receives radio waves superimposed with time information including Japan Standard Time, which is the so-called standard radio wave or long wave JJY, transmitted from the National Institute of Information and Communications Technology in Japan, to the received time information. There is a time recorder that corrects the time based on this. This time recorder is, for example, as disclosed in Patent Document 1. Standard radio waves have different frequencies and time code formats depending on the country. For example, standard radio waves such as WWVB (60 kHz) in North America and DCF77 (77.5 kHz) in Germany are known in Europe. For this reason, the time recorder is a product with different specifications for each country so as to have a receiving circuit corresponding to each standard radio wave and a time code analysis function.

Next, the operation of the time recorder in FIG. 1 will be described.
The relay unit 3 starts receiving time information from a parent device such as the relay devices 2A and 2B or other child devices under the control of the wireless system control unit 33 at a predetermined time. The receiving unit 31 detects a data signal including time information obtained by encoding a radio wave from the base unit received by the antenna. The radio system control unit 33 decodes the data signal detected by the receiving unit 31 and extracts time information. Based on this time information, the wireless system control unit 33 corrects the time measured by the time measuring unit 34. As a result, the standard time can be shared with the parent device.

  When the time correction is completed, the time information based on the time measured by the time measuring unit 34 is encoded, FM-modulated by the transmitting unit 32, and radio waves are transmitted by the antenna. As a result, time synchronization with other slave units is possible. In addition, as such an additional transmission function, it is possible to transmit the latest time information transmission request (command) to the parent device. It is possible to synchronize. If there is no need to provide time information to other slave units, or if the master unit needs to transmit time information periodically and receive this time information passively, the transmission function is unnecessary. Therefore, the transmission unit 32 may not be provided.

  In the time recorder unit 1B, the reception management unit 61 instructs the control unit 12 to forcibly start reception when a switch (not shown) of the setting unit 9 is operated in a predetermined manner or to start reception at a predetermined time. When the command is received, a reception start signal is output to the code generation unit 4 of the receiving device 1A. The predetermined time is a time set in advance by the setting unit 9 or a periodic cycle (for example, a two-hour cycle).

  When the code generation unit 4 receives the reception start signal output from the time recorder unit 1B, the code generation unit 4 starts generating and outputting the time code from the time information based on the time measured by the time measuring unit 34 of the wireless system control unit 33. The process until the time code is output will be described by taking a standard radio wave and a long wave JJY time code signal (hereinafter referred to as a JJY signal) as an example. As a premise, between the code generation unit 4 and the relay unit 3, the time information replaced with a character code (ASCII character or the like) is data-communication by non-procedure synchronous serial communication that is currently widely used. Shall. The details of the non-procedural synchronous serial communication method will be omitted.

  The code generation unit 4 that has received the reception start signal transmits a time information request command “$ SD” (Send all Data) to the wireless system control unit 33. Then, the wireless system control unit 33 uses the response data “$ TD *****” (Time Data) including the time information of the second update timing of the time measuring unit 34 immediately after receiving the time information request command as the final data. Will reply in sync with the update timing of that second. The code generation unit 4 extracts time information such as year / month / day / hour / minute / second / day of the week / leap second / daylight saving time from the response data. The extracted time information is converted into BCD (Binary Coded Decimal Notification), and a time code in the format of a JJY signal composed of 1 bit per second and 60 bits per frame is generated. The generated time code includes the minute, hour, day of the year, hour parity, minute parity, reserve flag (reserved as daylight saving time notice flag), year, day of the week, leap second information, and the frame marker “ Position markers from “M” and “P1” to “P5” and “P0”, and fixed bit 0 for interpolation of each data are added to form a 60-bit code. Based on the generated time code, the code generation unit 4 outputs to the output unit 5 together with second data to be output as a time code signal from the output unit 5 based on the second update timing.

  Regarding the generation of the time code here, taking the case of 17:45 on May 5, 2005 as an example, it is as follows. First, “M” is set as the data of 00 seconds, and “1”, “0”, “0”, “0”, “1”, “0” are BCD converted between 01 seconds and 08 seconds. “45” is set by “1”. Since a fixed bit of “0” is inserted at the 04th second in the minute data, actually, “1”, “0”, “0”, “0”, “0”, “1”, “0”, “1”. Next, 'P1' is set at 09th second, and the 10th and 11th seconds are “0” fixed bit, and the 14th second is “0” fixed bit. “0”, “1”, “0”, “0”, “1”, “1”, “1”, 17 hour data, 19th is “P2”, 20th and 21st Is a "0" fixed bit, and the 24th second is a "0" fixed bit. From the 22nd to the 28th, "0", "1", "0", "0", "0", " “Highest 2 digits of the day of the total”, which is 12 for 1 ”and“ 0 ”,“ P3 ”for the 29th second,“ 0 ”,“ 1 ”,“ 0 ”,“ from the 30th to the 33rd second 1 ”is 5 and“ the last digit of the total date ”. (The total date is the total of 125 days including the upper 2 digits and the lower 1 digit, and is the total number of days from January 1 to May 5. ), 34th and 35th seconds are "0" Fixed bit, 36th second is "0" which is even parity of "hour" data, 37th second is "1" which is even parity of "minute" data, 38th and 40th seconds are "0" “0” “Preliminary flag”, “P4” in 39 seconds, “0”, “0”, “0”, “0”, “0”, “1” between the 41st and 48th seconds "・" 0 "・" 1 "is the last two digits of 05," P5 "for the 49th second," 1 "," 0 "," "for the 50th to 52nd “0” is 4 “day of the week”, 53 and 54 seconds are “0” and “0” “leap second information”, 55 to 58 seconds are “0” fixed bit, 59 seconds “P0” is created.

  The output unit 5 that receives such a time code includes a base counter 51 for generating a cycle of 1 second as described above, a code counter 52 for code output that cyclically counts from 00 to 59, and a time code. A 60-bit code buffer 53 for temporary storage. After storing the time code sent from the JJY code generation unit 42 in the code buffer 53 and receiving the second data sent at the second update timing of the time counting unit 34, the base counter 51 is initialized, Second data is set in the code counter 52. As a result, the value of “second” measured by the time measuring unit 34 at the time of setting coincides with the value of “second” set in the code counter 52. Thereafter, the code counter 52 is updated at a 1-second cycle of the base counter 51. At the same time that the code counter 52 returns from 59 to 00 (becomes the second), the time code is acquired bit by bit from the code buffer 53 at the position corresponding to the count value of the code counter 52, and the ternary value specified by the JJY signal is obtained. The signal is converted to the received signal and output to the time recorder unit 1B as a time code signal is started. As described above, since the output of the time code signal is started from the time of the positive second after the code counter 52 starts counting, the time code stored in the code buffer 53 is “minute” from the timing at which the second data is set in the code counter 52. It is the value which advanced one digit. Further, every time the code counter 52 returns from 59 to 00, the digit of the “minute” of the time code in the code buffer 53 is advanced by one, and each digit such as “minute” and “hour” is sequentially updated. Here, the ternarized time code signal is a signal generated by one pulse per second, and its pulse width is matched to the logical value of each bit of the time code. This path width consists of three pulses of 0.2 seconds for the marker “M” or “Px”, 0.5 seconds for the logical value “1”, and 0.8 seconds for the logical value “0”. Is generated. The time code signal is output as a signal whose logical value can be determined by the code extraction unit 62 of the time recorder unit 1B. For example, an “H” level pulse is temporarily output.

  On the other hand, in the time recorder unit 1B, the code extraction unit 62 that has received the reception start signal from the reception management unit 61 is a time code composed of a pulse train that is generated by one pulse per second input from the output unit 5 of the receiving device 3. From the signal, a time code of 60 bits per frame expressed by a marker and a BCD of logical values “1” and “0” is extracted. The time code is extracted for each time information such as “minute” and “hour” in accordance with the time code format after detecting the head of the frame marker “M”, and the extracted time code is used as a time information determination unit. To 63.

  The process of extracting the time code by the code extracting unit 62 will be described in more detail as follows. First, when a reception start signal is received, a count of the base counter 62A serving as a reference for measuring the pulse period of the time code signal is started, and processing for synchronizing the base counter 62A and the pulse period of the time code signal is started. Be started. The base counter 62A has a reference clock of 1 ms for 1 count and returns to 0 when it counts 1000, and can count 1 second as in the time code cycle.

  Next, measurement of the interval between the rising edges of the pulse of the time code signal is started. The edge interval of the time code signal can be obtained from the difference between the count values of the base counter 62A read each time the rising edge is read and the count value of the base counter 62A when the rising edge is detected. It should be noted that an overflow due to the count value of the base counter 62A exceeding 1000 between both edges can be detected, and 1000 ms is added to the count value of the edge when it is read for the second time. It is possible to measure at intervals of more than a second. In addition, an edge time measuring timer for measuring the edge interval may be prepared. In this case, when a rising edge is detected, 0 starts, and at the second and subsequent rising edges, the timer value is read simultaneously. A timer for time measurement is set so that it starts zero again.

  In this way, when the detected pulse interval of the time code signal was about 1 second for four consecutive times, the average of the count values of the base counter 62A when the rising edge of the pulse was detected was obtained. By adding the average value to the base counter, the timing of the rising edge of the pulse and the count value “0” of the base counter 62A becomes substantially the same, and the pulse period of the input time code signal and the time for the time measurement of the code extraction unit 62 are measured. Synchronization with a 1-second cycle counted by the base counter 62A is performed.

  When the synchronization process of the base counter 62A is completed, detection of the pulse width of each pulse constituting the time code signal is started. This pulse width can be obtained from the count value of the base counter 62A when the falling edge of the time code signal is detected. From the pulse width thus obtained, if the pulse width is about 200 ms, it is determined as a marker, if the pulse width is about 500 ms, it is determined as a logical value “1”, and if the pulse width is about 800 ms, it is determined as a logical value “0”. Ternization is started.

  Next, a frame marker “M” indicating the beginning of the time code is detected from the ternary time code signal. Since the frame marker “M” is output continuously with the position marker “P0”, when a marker having a pulse width of about 200 ms can be detected twice in succession, the second marker is used as the frame marker “M”. " Thus, when the frame marker “M” is detected, the count of the second counter 62B that can count one minute with 60 counts starts from “00”, and the count value of the second counter 62B is used to specify the time code. Time information such as “minute” and “hour” is extracted from the second position.

  Next, an example of extraction of “minute” data will be briefly described. “Minute” data is in the position from 01 to 08 seconds as the count value of the second counter, and can be extracted from a 7-bit BCD without the “0” fixed bit located at 04 seconds. Assuming that “1”, “0”, “0”, “0”, “0”, “1”, “0”, “1” are detected in order from 01 seconds, the position is 04 seconds. If “0” is excluded, “1”, “0”, “0”, “0”, “1”, “0”, “1” are obtained and 45 can be determined. Similarly, “hour” data consisting of 17 BCDs from the 12th to 18th seconds excluding the 14th second is extracted, and 12 “total days” consisting of the BCDs from the 22nd to 28th seconds excluding the 24th second. "The upper 2 digits", BCD from the 30th to the 33rd second, "the last 1 digit of the total date", the 36th second "hour" even parity of the data "0", the 37th " “1” which is even parity of “minute” data, “reserved flag” “0” / “0” in the 38th and 40th seconds, and “year” data consisting of 05 from the 41st to 48th BCD The “day of the week” data consisting of 4 BCDs from the 50th to the 52nd seconds, and “leap second information” of “0” and “0” are extracted for the 53rd and 54th seconds, respectively. The time code for each time information extracted in this way is output to the time information determination unit 63.

  When receiving the reception start signal, the time information determination unit 63 initializes the determination register 63A for each time information such as “hour” and “minute”, and stores the time code input from the code extraction unit 62. . At the time of storage, after determining whether or not the value of information meaning each time code is normal, only the information determined to be normal is stored. For example, “minute” is a value from 00 to 59, and “hour” is a value from 00 to 23. Similarly, for the total date, “highest two digits of the total date” and “lowest digit of the total date” are used. A combined value of three digits from 001 to 366, a value from 00 to 99 for “year”, and a value from 0 to 6 for “day of the week” is determined as a normal value. Since “reserved bit” and “leap second information” are in four states represented by 2 bits, no particular determination is made. For “minute” and “hour”, a parity check is also performed to determine whether the number of logical values “1” is an even number with “minute parity” and “hour parity”. If the value of “Year” is a full year (other than a multiple of 4), it is determined whether the value is within 365.

  When the acquisition of all the time information is thus completed, the time information determination unit 63 stops the time measurement of the time measurement unit 64 and then corrects the time counter of the time measurement unit 64 with the acquired time information. Note that the second counter (not shown) of the time counter 64 is corrected with the value of the second counter 62B counted by the code extractor 62 because the value is the same as the second value of the time code. When the correction of the time measuring unit 64 is completed with all the time information, the time adjustment of the time measuring unit 64 is started when the base counter 62A of the code extracting unit 62 is 000, that is, at the timing of the second, and the time correction is completed. When the time correction is completed, the reception management unit 61 outputs a reception end signal to the code generation unit 4, the code extraction unit 62, and the time information determination unit 63. The code generation unit 4 stops the generation of the code signal of the output unit 5, and the code extraction unit 62 and the time information determination unit 63 stop the respective processes.

  In addition, although the attendance management process of the time recorder part 1B, the printing process to a time card, etc. are not explained in detail, these processes shall be performed based on the corrected time information.

  As described above, the time recorder 1 of the present example includes the receiving device 1A that receives the time information by the special radio of the time relay system 2 and converts the time information into a time code signal corresponding to the time code format of the standard radio wave, A time code signal is sent from the receiving apparatus 1A to the time recorder unit 1B. As described above, the time code signal is the same as the time code signal obtained by receiving the standard radio wave. Therefore, the reception management unit includes the existing time recorder that acquires time information from the standard radio wave and the time recorder 1 of this example. 61, the code extraction part 62, the time information determination part 63, and the time measuring part 64 can be made into the same structure. Therefore, when selling both the time recorder 1 using the time information relay devices 2A and 2B using special radio and the existing time recorder equipped with the standard radio wave receiving device, both can be shared. It becomes possible to hold down the cost.

  Next, a second embodiment of the present invention will be described. As shown in FIG. 2, the time recorder 1α of this example is provided with a code generator 4α instead of the code generator 4 of the time recorder 1 of the first embodiment shown in FIG. In addition to the JJY code generation unit 42, the code generation unit 4α includes a WWVB code generation unit 42α and a DCF77 code generation unit 42β that generate time codes compliant with the time code formats of the standard radio waves of WWVB in North America and DCF77 in Europe. With. The time recorder 1α includes an operation switch for selecting one of the three code generation units, the JJY code generation unit 42, the WWVB code generation unit 42α, and the DCF77 code generation unit 42β to generate a time code. The setting unit 14 is provided. In accordance with the designation of the selection signal from the setting unit 14, the code generation unit 4α generates the selected time code. Further, the time recorder 1α includes an output unit 5α instead of the output unit 5. The output unit 5α basically has the same configuration as that of the output unit 5, and each bit read from the code buffer 53 is subjected to an appropriate pulse by the same conversion process corresponding to the time code selected by the selection signal of the setting unit 14. The signal is converted into a pulse having a width and output to the time recorder unit 1Bα as a time code signal.

  Further, the time recorder unit 1Bα includes a code extraction unit 62α and a time information determination unit 63α corresponding to any standard wave of the long wave JJY, WWVB, or DCF77. The code extraction unit 62α and the time information determination unit 63α use the same configuration of an existing time recorder that supports any one of the long wave JJY, WWVB, and DCF77 standard radio waves.

  As described above, in the time recorder 1α, the receiving device 1Aα is compatible with any standard wave of the long wave JJY, WWVB, and DCF77, and is configured to be detachable from the time recorder unit 1Bα. The receiving device 1Aα can select and generate a desired time code signal by an operation from the setting unit 14, and can respond to the time recorder unit 1Bα corresponding to any standard wave of JJY, WWVB, and DCF77. ing. For this reason, there is an existing time recorder provided with a receiving device 1Aα that receives time information in a unique format, and a receiving device that receives time information with standard radio waves for each market such as North America (WWVB) and Europe (DCF77). When the time recorder is sold together, the receiving device 1Aα can be shared regardless of the market, and the cost can be reduced. In this case, the relay device 2A serving as the parent device is configured to extract time information from standard radio waves such as long wave JJY, WWVB, DCF77, and GPS, and transmit the time information as a unique format.

  Next, a third embodiment of the present invention will be shown. In the time recorders of the first and second embodiments described above, for example, the receiving device 1A and the time recorder unit 1B are detachable, and a time code signal corresponding to the time code format of the standard radio wave is sent from the receiving device 1A to the time recorder unit 1B. It is configured. Therefore, in the third embodiment, as shown in FIG. 3, the time recorder 1β is provided with a standard radio wave receiver 1C to generate a time code signal, and the receiver 1C and the time recorder unit 1B can be attached and detached. Is.

  Here, the receiving device 1C corresponds to the long wave JJY as the standard radio wave, but may correspond to other standard radio waves such as WWVB, DCF77, etc. in accordance with the time recorder unit. The receiving device 1C includes a long wave receiving circuit 15 connected to an antenna. Although the long wave receiving circuit 15 is not shown, the long wave receiving circuit 15 is composed of an amplifying circuit and a tuning circuit for a radio wave signal received by an antenna, a detecting circuit, and the like. However, since a common function is used for the function of detecting a time code signal, detailed description thereof is omitted.

  The operation of the time recorder 1β of this example is as follows. A reception start signal is output from the reception management unit 61 of the time recorder unit 1B to the code extraction unit 62, the time information determination unit 63, and the long wave reception circuit 15. Then, the long wave receiving circuit 15 starts receiving the radio wave signal, and the detected time code signal of the long wave JJY is input to the code extracting unit 62 of the time recorder unit 1B.

  Similar to the first embodiment described above, the code extraction unit 62 starts counting of the base counter 62A, and synchronizes the time code signal with the marker or the pulse cycle of the time code signal input from the long wave receiving circuit 15. A ternarization into a logical value “1” and a logical value “0” is performed. The ternarized time code is converted into a time code such as “hour” or “minute” expressed in BCD and output to the time information determination unit 63.

  The time information determination unit 63 initializes the determination register 63A for each time information such as “hour” and “minute”, and then displays “hour” or “minute” expressed in BCD input from the code extraction unit 62. Is stored in the register 63A. When the acquisition of all the time information is completed, the time measurement by the time measurement unit 64 is stopped, and then the time of the time measurement unit 64 is corrected by the acquired time information, and the time measurement by the time measurement unit 64 is resumed. This completes the time correction.

  According to this example, a receiving device 1A that receives time information in a unique format or a receiving device 1C that has a standard radio wave time code format can be connected to the time recorder unit 1B. Therefore, for example, the receiving device 1C can be sold as an option of the time recorder 1 shown in FIG. In this way, a time recorder equipped with a unique receiving device or a standard radio wave receiving device and a time recorder not equipped with a receiving device can be sold together in accordance with market needs, and costs can be reduced.

  In each of the above-described embodiments, the receiving device and the time recorder unit are divided into two functional blocks so as to be detachable. However, both may be integrated.

  Next, a fourth embodiment of the present invention will be shown. The time recorders of the above-described embodiments are configured to use a configuration for performing extraction processing and determination processing of the time code format of an existing time recorder. However, with the commercialization of such time recorders, these extraction processing and determination processing Instead of the configuration for this, it is possible to commercialize a time recorder using a configuration in which data and commands are directly communicated with the data communication unit 35 and time information is obtained from the obtained data. In this example, such a configuration is shown.

  The configuration of the time recorder 1γ of this example is as shown in FIG. 4, and the receiving device 1Aγ is substantially the same configuration as the relay unit 3, and is configured to be detachable from or separate from the time recorder unit 1Bγ. Although not shown, for example, a signal line and a power line for sending data and commands can be attached to and detached from the connection unit of the time recorder unit 1Bγ, and the signal line and the power line are connected to the corresponding circuit of the time recorder unit 1Bγ via the connection unit. It has the structure connected to an element. For this reason, the receiving apparatus 1Aγ may be configured by adding a configuration in which the communication unit 35 is selectively connected to an external communication line in the receiving apparatus 1A. The time correction unit 6γ of the time recorder unit 1Bγ includes a communication unit 16 and a time information extraction unit 17 in place of the code extraction unit and the time information determination unit described above. The communication unit 16 communicates data and commands directly with the data communication unit 35 of the receiving device 1Aγ. The time information extraction unit 17 extracts time information from the response data from the data communication unit 35 obtained via the communication unit 16 and corrects the time of the time measuring unit 64.

Next, the operation of this example will be described in particular with respect to the configuration different from the above-described embodiments.
Upon receiving the reception start signal from the reception management unit 61, the communication unit 16 transmits a time information request command “$ SD” (Send all Data) to the data communication unit 35. Then, the wireless system control unit 35 uses the response data “$ TD *****” (Time Data) including the time information of the second update timing of the time measuring unit 34 immediately after receiving the time information request command as the final data. Will reply in sync with the update timing of that second. The data communication unit 35 outputs the response data to the time information extraction unit 17. Time information extraction unit 17 Extracts time information such as year, month, date, hour, minute, second, day of the week, leap second, daylight saving time from the response data.

  When the extraction of all the time information is completed, the time information extraction unit 17 stops the time measurement of the time measurement unit 64 and then corrects the time counter of the time measurement unit 64 with the acquired time information. Correction of the time information value of the time measuring unit 64 is completed for all the time information. For example, the second value of the response data obtained immediately before is set as the second counter value of the time measuring unit 64 (not shown). The timing of the time counting unit 64 is restarted at the acquisition timing of the final data of the response data, and the second value is updated. As a result, the seconds of the timer unit 34 and the timer unit 64 are synchronized, and the time correction of the timer unit 64 is completed. When the time adjustment is completed, the reception management unit 61 outputs a reception end signal to the data communication unit 16 and the time information extraction unit 17 to end these operations.

  In this example, the receiving device 1Aγ can have the same configuration as that of the relay unit 3 of the receiving device 1A. In the time correction unit 1Bγ of the time recorder unit 1Bγ, the data communication unit 16 and the time information extraction unit are partially configured in the above embodiments. By substituting 17, the time recorder corresponding to the time relay system 2 can be commercialized, and the product variations can be abundant at low cost. The receiving device 1Aγ may be configured by adding a configuration that allows the data communication unit 35 to be selectively connected to an external signal line to the relay unit 3 of the receiving device 1A. The example time recorder and receiving device can be shared, and product variations can be enriched at low cost. Further, since the receiving device 1Aγ and the time recorder unit 1Bγ are configured to be detachable, they can be sold separately, and according to the needs of the market, the time recorder 1γ provided with the receiving device 1Aγ corresponding to the time relay system 2, and the reception The time recorder 1γ without the device can be sold together, and the cost can be reduced.

  Further, the above-described relay unit that relays the specific low-power radio may be specialized only in the reception function of receiving a radio signal from the parent device or the child device of the time relay system.

  In the first and second embodiments described above, when the code generation unit detects the reception start signal from the time recorder unit, the generation of the time code is started. A time information request command may be periodically generated to the control unit 33, and a time code may be always generated.

  In the first and second embodiments described above, the code generation unit is described as acquiring time information from the wireless system control unit 33 by the data communication unit. However, the time of the time measuring unit 34 of the wireless system control unit 33 is described. The information may be directly referred to, and the data communication unit may be omitted. Further, the code generation unit may be configured to directly refer to the time information of the time measuring unit 34 of the wireless system control unit 33, and the time code signal may be constantly output by the generation and output unit of the time code.

  In the first, second, and fourth embodiments described above, non-procedure synchronous serial communication is used as data communication between the relay unit and the code generation unit and communication between the data communication units. Not limited to this, XMODEM and ZMODEM may be replaced with various methods and configurations, such as a dedicated procedure specialized for the product, or a combination with asynchronous serial communication. .

  In each of the above-described embodiments, the time recorder for attendance management has been described as an example of the time recording device of the present invention. However, the time recording device of the present invention is, for example, a time stamp for printing time on various slips. Also good.
