  Further, in order to synchronize the operation of the clock means 135 of the program timer main body 100 and the clock means 240 of the setting device 200, the program timer main body 100 outputs a synchronization signal based on the signal of the clock means 135. The setting device 200 includes a synchronization input determination unit 249 that determines a synchronization signal from the synchronization output generation unit 144, a synchronization start signal generation unit 236 that outputs a synchronization start signal based on the signal of the clock unit 240, and a setting Connector connection determining means 237 for determining that the connector is connected when the device 200 is attached to the program timer main body 100.

  Hereinafter, the synchronization operation of each clock means between the program timer main body 100 and the setting device 200 will be described in detail. First, when the setting device 200 is connected to the program timer main body 100, the setting device 200 determines that it is connected to the program timer main body 100 from the determination output of the connector connection determination means 237. Thereafter, when 30 seconds have elapsed as a result of the time measured by the clock means 240, a synchronization start signal is sent from the synchronization start signal generation means 236 to the synchronization output generation means 144 of the program timer body 100. Upon receiving the synchronization start signal, the synchronization output generating means 144 clears the count value of the built-in counter to 0, and thereafter sends the synchronization signal to the setting device 200 every minute. The setting device 200 corrects the time measured by the clock means 240 every minute according to the synchronization signal. Thereafter, the correction operation is continued while the setting device 200 is connected to the program timer main body 100.

In the setting device 200, the time of the control output ON operation from the control output means 137, 138 to the external device is set by a program. The control output ON operation from the control output means 137, 138 to the external device is set. In order to accurately match the timing of the analog clock means when the time measured by the analog clock means reaches the set time in the program, a little before the time when the control signal is actually output from the control output means 137, 138, The output from the program determination means 245 of the setting device 200 needs to be given to the program timer body 100. Therefore, the time ΔT required to give the output of the program determination means 245 to the program timer body 100 is set as follows.
ΔT> t1 + t2 + t3
(T1: Time required to detect the synchronization input by the program timer body 100, t2: Processing time from when the synchronization input is received by the setting device 200 until actual output is performed, t3: Synchronization input by the program timer body 100 (The difference between the clock times of the clock means 240 of the setting device 200 and the clocking device 135 of the program timer main body 100, which is generated from the detection until the output is actually performed by the setting device 200)
Note that the program timer main body 100 and the setting device 200 have a sub-clock provided from a crystal oscillation circuit (for example, the crystal oscillation circuit 155 in FIG. 15) as a synchronous input.

  For example, if the synchronization input is detected when the program timer body 100 and the setting device 200 receive the synchronization input given every 30 ms twice, the time t1 required to detect the synchronization input is 30 ms ≦ t1 ≦. 60 ms. If the internal processing time of the program determining means 245 of the setting device 200 is α (≦ 10 ms), the processing time t2 from when the setting device 200 accepts the synchronization input until the actual output is performed is 30 ms + α ≦ t2 ≦ 60 ms + α. It becomes. Furthermore, if the above-described time correction is performed every minute when 30 seconds have elapsed from every minute (when the second hand points to 12), the clock means 240 of the setting device 200 and the clock of the program timer main body 100 The time difference t3 with the means 135 is −5 ms ≦ t3 ≦ 5 ms. Here, 5 ms is the maximum value of the oscillation error of the crystal resonator constituting the crystal oscillation circuit of the program timer body 100.

  From the above, ΔT> 125 ms. Therefore, in the present embodiment, the program determination unit 245 of the setting device 200 sets the program timer body 100 to the program timer main body 100 500 ms before the set time of the program for turning on the control output from the control output units 137 and 138 to the external device. The output is given.

  Next, various settings of the program timer will be described.

The setting device 200 controls the output of the control output units 137 and 138. The control program to be set can be set, confirmed, and changed. In the following description, two circuits that can be controlled by the respective control output means 137 and 138 are referred to as “circuit 1” and “circuit 2”, respectively.

  The mode change switch 204 is provided on the left side of the display and is configured by using a slide switch 204a that is slid in the vertical direction.

  The various setting switches 202a to 202s are assigned to the respective functions in each mode. With the setting device 200 attached to the program timer body 100, the (1) normal (time display) mode is used. A reception day confirmation switch is assigned to the switch 202a, and a forced reception setting switch is assigned to the switch 202b.

  Each of the switches 202m to 202r is composed of a push button that allows a seesaw operation in the vertical direction and two switches that are turned on and off by the operation of the push button. When the upper side is pressed, 1 is added, and when the lower side is pressed, 1 is subtracted.

Further, the switches 202a to 202i are well-known push switches composed of push buttons and switches. These switches are mounted on a printed circuit board.

  Hereinafter, the operation of correcting the current time of the clock means 135 and 240 based on the standard time will be described with reference to FIGS.

  First, a long wave that conveys Japan Standard Time with high accuracy is a radio wave operated by the National Institute of Information and Communications Technology, which is called a standard radio wave by the National Institute of Information and Communications Technology. Is called a standard time radio wave to clearly express that it is a radio wave including time information. This standard time radio wave is transmitted at a frequency of 40 KHz from the Fukushima long wave station (Otakadoyayama) and at a frequency of 60 KHz from the Kyushu station (mountain Hagane). This standard time radio wave varies depending on the distance from the long wave station, and the location of the antenna (for example, terrain, buildings, etc.), the influence of the weather and ionospheric conditions, and the transmission of power towers, high voltage lines, television and radio In addition to being affected by electric or magnetic fields from towers, train overhead lines, etc., they are blocked or reflected by operations of aircraft, trains, automobiles, and the like.

  When such a standard time radio wave is received by the radio wave receiving means 331, radio wave noise close to the frequency of the standard time radio wave generated from an electronic device in an aircraft, train, automobile, factory, office, etc. is also captured at the same time. The electric signal in the means 331 includes not only an electric signal based on the standard time radio wave but also an electric signal due to radio noise close to the frequency of the standard time radio wave, a partially missing electric signal, and the like. There is a signal.

  Then, the time code forming pulse generating means 333 generates a time code forming pulse including a pulse for forming a time code of the standard time from the standard time radio wave. The time code forming pulse includes the signal voltage converting means 339 and the terminal block 341. , 146, and signal voltage conversion means 142, and input to time encoding means 126 of program timer body 100.

  The time encoding unit 126 uses the time code forming pulse as the time code of the standard time, the time data generating unit 127 generates the standard time from the time code of the standard time, and the radio wave reception control unit 129 generates the generated standard. Based on the time, an instruction to correct the current time of the clock means 135 is given to the time correction means 148, and the time correction means 148 corrects the current time of the clock means 135 according to this instruction.

  Further, the generated standard time is input to the radio wave reception control means 246 of the setting device 200 via the connectors 145 and 229, and the radio wave reception control means 246 determines the time of the clock means 240 based on the generated standard time. An instruction to correct the current time is given to the time adjusting means 233, and the time adjusting means 233 corrects the current time of the clock means 240 according to this instruction.

  The time encoding state in the time encoding unit 126 and the time data generation state in the time data generation unit 127 are stored in the radio wave reception operation control state storage unit 149.

  The current time adjustment operation is performed by an automatic reception operation or a forced reception operation. During the automatic reception operation, the standard time radio wave is periodically received by the radio wave reception unit 331, and the radio wave reception control unit 129 is in a radio wave reception operation control state. If the time encoding state stored in the storage unit 149 is a state in which the generated time code forming pulse is the time code of the standard time, the clock unit 135 is configured based on the standard time generated from the time code. An instruction to correct the current time is given to the time correction means 148, and the radio wave reception control means 246 also gives an instruction to correct the current time of the clock means 240 to the time correction means 233.

  At the time of forced reception, if the forced reception setting switch 202b is manually operated, the radio wave receiving means 331 forcibly receives the standard time radio wave. Then, the radio wave reception control unit 129 causes the time encoding unit 126 to try the time encoding using the time code forming pulse generated by the forced reception as the time code of the standard time, and the standard generated from the time code. Based on the time, an instruction to correct the current time of the clock means 135 is given to the time correction means 148, and the radio wave reception control means 246 also gives an instruction to correct the current time of the clock means 240 to the time correction means 233.

  FIGS. 6A to 6D are diagrams showing schematic signal waveforms until a time code forming pulse is generated from the standard time radio wave of the program timer according to the embodiment of the present invention. From the long wave station, a standard time signal with a pulse width of 0.2 s ± 5 ms as a marker (M) and a position marker (P0 to P5), a standard time signal with a pulse width of 0.8 s ± 5 ms as a binary number, and a binary number 1, a standard time radio wave having a pulse width of 0.5 ms ± 5 ms is transmitted by a carrier wave having a frequency of 40 KHz or 60 KHz. 6A to 6D show examples in which the time code of the standard time of the long wave station is 25 minutes.

  FIG. 6A shows a standard time radio wave in the long wave station, and since the transmission output of the long wave station is determined, the strength of the standard time radio wave is constant.

  FIG. 6B shows an electric signal waveform obtained from the standard time radio wave received by the radio wave receiving means 331. The electric signal waveform of the radio wave receiving means 331 includes an electric signal waveform including signal level noise (0 second to 1 second), an electric signal waveform including swell (1 second to 2 seconds), and an electric signal waveform including narrow noise. (2 seconds to 3 seconds), electrical signal waveform including low level noise (3 seconds to 4 seconds), weak standard time radio signal waveform (4 seconds to 5 seconds), strong standard time radio signal waveform ( 5 seconds to 6 seconds), an electric signal waveform including high level noise (6 seconds to 7 seconds), a standard time signal waveform lacking a signal (7 seconds to 8 seconds), and the like.

  FIG. 6C shows a rectangular pulse in which the time code is inverted with the output waveform of the decoder circuit input to the decoder circuit after full-wave rectification by performing gain control on the electric signal waveform of the radio wave receiving means 331 and envelope detection. This is an electric signal waveform including In this decoder circuit, an electric signal waveform of 48 dB or more and 110 dB or less and having a pulse width longer than 0.1 s and shorter than 0.3 s is recognized as a marker (M) or a position marker (P0 to P5). An electric signal waveform having a pulse width longer than 0.35 s and shorter than 0.55 s is recognized as a binary number 1, and an electric signal waveform having a pulse width longer than 0.65 s and shorter than 0.85 s is binary. It is recognized as 0. Also, the noise of the electric signal waveform whose pulse rise is not 1 second apart, the electric signal waveform with a narrow width, and the electric signal waveform of a low level are ignored.

  From the electric signal waveform of the radio wave receiving means 331 (FIG. 6B) to the formation of an electric signal waveform (FIG. 6C) including a rectangular pulse obtained by inverting the time code is performed by the time code receiving IC. . This receiving IC has a function of confirming the pulse width or the rising interval of the rectangular pulse of the time code, and an inappropriate rectangular pulse due to a change in noise or electric field strength is not output from the decoder circuit.

  FIG. 6D shows a time code forming pulse after signal voltage conversion of a time code pulse generated by inverting the output waveform of the decoder circuit. This time code forming pulse is a delay of the standard time radio wave, a delay due to the rise characteristic of the electronic circuit for gain control of the electric signal waveform, and a rectangular pulse of the electronic circuit that detects the electric signal waveform after gain control to make a rectangular pulse. Although a slight delay occurs compared to the rising of the standard time radio wave of the long wave station due to a delay due to the rising characteristic, etc., this slight delay is not mentioned in the present invention.

  FIG. 4 shows the state of the display unit 201 in the (1) normal (time display) mode in a state where the setting device 200 is attached to the program timer main body 100. The display unit 201 includes a time display unit 201a. In addition to the current time (time, day of the week) displayed on the day of the week display unit 201b, a unit connection state display unit 201c, a radio wave intensity display unit 201d, and a reception completion display unit 201e are displayed.

  The reception unit connection state display unit 201c is lit when the radio wave reception unit 300 is correctly connected, the power is normally supplied from the program timer main body 100, and the signal is normally transmitted from the radio wave reception unit 300. Further, it blinks at 2 Hz when the connection state such as erroneous connection or non-connection is abnormal, when the signal from the radio wave reception unit 300 is abnormal, or when there is no signal from the radio wave reception unit 300. The reception unit connection state display unit 201c corresponds to the reception unit connection state display unit 235c in FIG. 1, and the radio wave reception control unit 246 includes a radio wave reception unit connection state determination unit and performs display control.

  The radio wave intensity display unit 201d determines the radio wave state in four stages based on the data of the electric field intensity and the radio wave reliability from the radio wave receiving unit 300, and displays them with three bars according to the determination result. Three bars are lit when the radio wave condition is the best, two bars are lit when the level is medium, one bar is lit when the level is low, and it is not lit when the level is worst. In FIG. 1, the radio field intensity display unit 201 d corresponds to the radio field intensity display unit 235 a, and the radio field intensity determination unit 128 includes the electric field intensity determined by the electric field intensity determination unit 336 and the time code formation pulse reliability determination unit 334. The radio wave reception control means 246 displays the radio wave intensity on the radio wave intensity display means 235 based on the reliability of the time code forming pulse determined in step S2.

  The reception completion display unit 201e can obtain the standard time signal from the standard time radio wave received by the radio wave receiving unit 300 during the forced reception operation or automatic reception operation, and can correct the current time of the clock means based on the standard time. Turns on when it is possible, and turns off when the standard time cannot be obtained and the time cannot be corrected. When the forced reception setting switch 202b is pressed, the reception completion display unit 201 blinks. The reception completion display unit 201e corresponds to the reception completion display unit 235b in FIG. 1, and the radio wave reception control unit 246 displays a reception status determination unit that displays a reception completion state when the current time is successfully corrected. Provide display control.

  Further, FIG. 7 is a diagram showing the display unit 201 during confirmation of reception day of the week that displays the day of the week when the standard time radio wave is received and the current time of the clock means is corrected. When the setting device 200 is attached to the program timer main body 100, when the mode selector switch 204 is switched to the normal (time display) mode and the reception day confirmation switch 202a is pressed, the standard time signal is received one week before that day. The standard time signal is obtained from the day of the week (day of the week display unit 201b) for which the current time of the clock means can be corrected based on the standard time, and is displayed blinking at 1 Hz together with the reception day confirmation in-progress display unit 201f. The blinking display of the day of the week is performed only for a predetermined time (for example, 30 seconds) after the reception day confirmation switch 202a is pressed, and when the predetermined time is passed, the display of the current day of the week is returned. If the reception day confirmation switch 202a is pressed while the day of the week is blinking, the blinking day of the week is turned off and the current day of the present time is turned on. In the reception day confirmation operation in FIG. 1, the reception day of the week when the standard time radio wave is received and the current time of the clock means is corrected is stored in the radio wave reception control storage means 247 and operated by the reception confirmation operation means 232b. The reception day of the week is displayed on 235 and controlled by the radio wave reception control means 246.

  In addition, the frequency selection means 332 in FIG. 1 can select which radio wave is received among standard time radio waves with a carrier frequency of 40 KHz or 60 KHz. Further, a signal corresponding to the frequency selected by the reception frequency identification signal generation means 337 is generated, and the selected frequency is displayed on the reception frequency display means 335b. In the present embodiment, any one of the 40 KHz reception display LED 306a and the 60 KHz reception display LED 306b is lit.

  FIG. 8 is a flowchart showing a part of the main routine of the program for controlling the operation of the program timer. Initial processing (step S1), power failure mode processing (step S2), analog clock processing (step S3), radio wave reception processing (Step S4), manual switch control (Step S5), and the like.

  In the initial processing of step S1, the state of the internal registers is reset to the initial state.

  In the power failure mode processing of step S2, the operation is switched to the operation by the power failure compensation battery at the time of commercial power failure.

  In the analog clock control in step S3, a process of periodically sending a notification voice storage update command from the setter control circuit 253 to the notification voice control circuit 273 is performed.

  In the radio wave reception process of step S4, the current time of the clock means 135 and 240 is corrected based on the standard time radio wave received by the radio wave receiving unit 300.

  In the manual switch control in step S5, the switch operation of the program timer body 100 is determined.

  FIG. 9 is a flowchart showing the radio wave reception process in step S4 in the program timer body 100. First, it is determined whether or not the radio wave receiving function is provided (step S10). In this embodiment, it is determined that the radio wave receiving unit 300 is connected to the program timer main body 100 and has a radio wave receiving function. However, if the radio wave receiving unit 300 is not connected, it is determined that the radio wave receiving unit 300 is not equipped with a radio wave receiving function. Then, the process ends.

  If it is determined that the radio wave reception function is provided, detection data processing is performed based on the time code forming pulse transmitted from the radio wave reception unit 300 (step S11), and then the electric field strength and radio wave reliability from the radio wave reception unit 300 are processed. Radio wave intensity data processing is performed to determine the radio wave intensity based on each signal (step S12). Next, whether or not the radio wave receiving unit 300 is correctly connected to the program timer main body 100, a signal from the radio wave receiving unit 300 is determined. A receiving unit connection state check is performed to determine whether or not is normal (step S13), and this process ends.

  FIG. 10 is a flowchart showing the detection data processing in step S11 in the program timer body 100. First, it is determined whether or not the noise prevention timer is operating (step S20). This noise prevention timer ignores a signal input during 900 ms from the rise of the time code forming pulse transmitted from the radio wave receiving unit 300. If the noise prevention timer is in operation, this process ends. . If the noise prevention timer is not in operation, the operation proceeds to each operation according to the current phase 1 operation (step S21).

  Hereinafter, the operation of Phase 1 will be described using the pulse waveform of 200 ms in FIG. First, if it is in the instruction waiting (initial value) state, it shifts to a pulse-off waiting state (step S22) (this state is indicated by a in FIG. 11), and this processing is terminated.

  If it is in the pulse-off waiting state, it is determined whether or not the pulse is off (step S23). If the pulse is not off, this process is terminated. If the pulse is off (this state is indicated by b in FIG. 11), the process shifts to a pulse-on waiting state (step S24) and the process is terminated.

  If it is in the pulse-on waiting state, it is determined whether or not the pulse is on (step S25). If the pulse is not on (this state is indicated by c in FIG. 11), this process is terminated. If the pulse is on (this state is indicated by d in FIG. 11), the process proceeds to the pulse measurement (step S26), the pulse length measurement is started (step S27), and this process is terminated.

  If the pulse measurement is in progress, it is determined whether or not the pulse is off (step S28). If the pulse is not off, this processing is terminated (this state is indicated by e in FIG. 11). If the pulse is off (this state is indicated by f in FIG. 11), the process shifts to a pulse-on waiting state (step S29), and the pulse length is determined (step S30). The determination of the pulse length is OK if it is 200 ms ± 100 ms, 500 ms ± 100 ms, 800 ms ± 100 ms, NG if it is outside the above range, and if the determination of the pulse length is OK, the pulse interval is determined. (Step S31) If the determination of the pulse length is NG, this process is terminated.

  To determine the pulse interval, the pulse interval checker is operated for 1800 ms from the falling edge of the pulse, and when the falling edge of the next pulse occurs outside the range of 1800 ms (NG), the block work buffer BB described later is initialized. (Step S32).

  Then, after initialization of the block work buffer BB or when the next pulse falls within the range of 1800 ms in the determination of the pulse interval (OK), data analysis processing is performed (step S33), and the noise prevention timer Is started (step S34), and this process is terminated.

  Note that the check interval T1 in FIG. 11 is several ms.

  Next, FIGS. 12A to 12I show the flow of the data analysis process in step S33 in the time encoding unit 126 and the time data generation unit 127 at the time of automatic reception. First, data is sequentially stored in the 60-digit block back buffer BB until the minute position is determined (FIG. 12A). When the marker M is generated twice and the marker M is generated 9 seconds after the second marker M and the minute position is determined, only the minute data is transferred to the first-stage buffer FB (FIG. 12B). ).

  Next, the subsequent data is stored in the first stage buffer FB (FIG. 12C).

  Next, when the data in the first stage buffer FB is completed, the data is digitized and stored in the reception buffer RB (FIG. 12 (d)).

  Next, it is checked whether or not there is an impossible value in the data in the reception buffer RB, and the validity is checked. If the data is valid, a carry is performed for one minute (FIG. 12 (e)).

  Next, the data in the reception buffer RB is stored in the comparison buffer CB (FIG. 12 (f)).

  Then, the processing shown in FIGS. 12A to 12D is performed on the next one-minute data, and the data in the reception buffer RB is compared with the data in the comparison buffer CB (FIG. 12G). If the results match, the date is calculated from the total date of the data in the reception buffer RB and stored in the communication buffer AB (FIG. 12 (h)). Only when the “hour”, “day”, “month”, or “year” has changed, the data in the communication buffer AB is carried by one minute, and the data is transmitted to the setting device 200 at the next 0 second timing ( FIG. 12 (i)).

  During automatic reception, the above operation is repeated every minute.

  Further, FIGS. 13A to 13G show the flow of the data analysis process in step S33 during forced reception. First, data is stored in order in the 60-digit block back buffer BB until the minute position is determined (FIG. 13A). When the marker M is generated twice and the marker M is generated 9 seconds after the second marker M and the minute position is determined, only the minute data is transferred to the first-stage buffer FB (FIG. 13B). ).

  Next, the subsequent data is stored in the second-stage buffer SB (FIG. 13C).

  Next, when the marker M is stored in the second-stage buffer SB, it is determined whether the first-stage buffer FB and the second-stage buffer SB are valid. If the second-stage buffer SB is valid, the second-stage buffer SB is determined. The data in the buffer SB is stored in the first stage buffer FB (FIG. 13 (d)).

  Next, the processing in FIG. 13D is repeated, and when the data in the first-stage buffer FB is completed, the data is digitized and stored in the reception buffer RB (FIG. 13E).

  Next, it is checked whether or not there is a numerical value that is not possible in the data of the reception buffer RB, and the validity is checked. If the data is valid, a one-minute carry is performed (FIG. 13 (f)).

  Next, the data in the reception buffer RB is stored in the comparison buffer CB, and a carry is performed for every 0 second until the comparison data is completed in the reception buffer RB (FIG. 13 (g)).

  Then, the processes shown in FIGS. 13A to 13E are performed on the data after the next one minute.

  Next, the data in the reception buffer RB and the data in the comparison buffer CB are compared (FIG. 13 (h)). If the comparison results match, the date is calculated from the total date of the data in the reception buffer RB, The data is stored in the communication buffer AB (FIG. 13 (i)), the data in the communication buffer AB is carried by one minute, and the data is transmitted to the setting device 200 at the next 0 second timing (FIG. 13 (j)). .

  If there is no data in the communication buffer AB even after 15 minutes from the start of forced reception, the reception operation is forcibly terminated.
