Description

  The present invention relates to an electronic timepiece apparatus including a timepiece circuit having a crystal oscillator, and more particularly to an electronic timepiece apparatus capable of adjusting the timekeeping operation of the timepiece circuit. The present invention also relates to an electronic device and a control system that operate using the date and time counted by the electronic timepiece device.

  Conventionally, in control systems that control load devices such as lighting devices or air conditioners, and management systems that manage alarms from alarms, opening and closing of electric locks, etc., timer control and timekeeping within that system For this purpose, an electronic timepiece is incorporated in the system. Many of the electronic timepiece devices installed in the system in this way employ a timepiece that measures the time based on the oscillation frequency of the crystal resonator. In addition, the clock circuit that measures the time based on the transmission frequency of the crystal resonator has a problem that an error occurs in the time measured due to the environmental temperature because the oscillation frequency of the crystal oscillator fluctuates due to a temperature change.

  As an electronic timepiece device that corrects the error in the time measured due to the environmental temperature, the ambient temperature in a plurality of operation modes with different operation states is stored, and the time determined by the error determined by the ambient temperature corresponding to the operation mode of the device There has been proposed a real-time clock control device that corrects (see Patent Document 1). The real-time clock control device according to Patent Document 1 stores ambient temperatures based on each operation mode of a multi-function peripheral including the real-time clock control device. Then, the ambient temperature is estimated based on the operation mode of the multifunction device, and time correction is performed using a correction profile suitable for the estimated ambient temperature. Furthermore, Patent Document 1 also discloses a real-time clock control device having a function of correcting the estimated ambient temperature for each installation region by storing a reference temperature difference for each region. There has also been proposed an electronic timepiece device that corrects the time measurement using a time error table per day based on the monthly average temperature (see Patent Document 2).

JP 2008-064678 A JP 2003-240884 A

  Since the real-time clock control device disclosed in Patent Document 1 estimates the ambient temperature according to the operation mode of the multifunction peripheral, accurate time adjustment is possible in places where the temperature is constantly adjusted. However, indoors where the temperature is adjusted only when a person is in the room or outdoors where there is no temperature control, it is also affected by the temperature that changes depending on the season. There will be a time when the time will deviate significantly.

  On the other hand, Patent Document 2 includes a time error table based on the monthly average temperature, so that the time measurement can be corrected according to the monthly average temperature. However, in regions where temperature fluctuations are small, depending on the season, the monthly average temperatures of the preceding and succeeding months may be approximately equal and may be stored in the time error table. Conversely, in regions with large temperature fluctuations, the temperature change in January is severe depending on the season, so correction of the timekeeping time is required on a daily basis, and correction based on the monthly average temperature is insufficient. End up.

  In view of such a problem, an object is to provide an electronic timepiece device which can minimize the memory amount of the temperature correction table by storing the temperature correction timing effective for correcting the timekeeping time. To do.

  In order to achieve the above object, an electronic timepiece according to the present invention includes a clock unit that counts a clock signal based on an oscillation operation of a crystal oscillator and clocks the date and time, and a frequency adjustment that adjusts the frequency of the clock signal. An electronic clock device comprising: a frequency setting unit that is predetermined by a temperature characteristic of an oscillation frequency of the crystal oscillator and a transition of an annual ambient temperature; The temperature correction table stored together with the parameter for determining the adjustment amount and the date and time measured by the time measuring unit coincide with one of the setting timings stored in the temperature correction table. A parameter corresponding to the set timing is read from the temperature correction table, and an adjustment amount corresponding to the read parameter is determined by the frequency adjustment unit. A correction value setting unit that, characterized in that it comprises a.

  At this time, the set timing may be determined by the date and time when the average temperature for a predetermined time has changed by a predetermined amount. That is, based on the annual ambient temperature transition, each time the temperature difference reaches a predetermined value, the setting timing is determined, and the average temperature at that time or the frequency deviation of the oscillation frequency of the crystal oscillator is stored as the parameter. To do. As a result, it is not necessary to store the setting timing at which the temperature difference is small and the adjustment amount by the frequency adjustment unit does not change.

  The set timing may be determined by a date and time when a frequency deviation based on an average temperature for a predetermined time of the oscillation frequency of the crystal oscillator changes by a predetermined amount. That is, based on the annual ambient temperature transition, the set timing is determined every time there is a predetermined value variation in the frequency deviation of the oscillation frequency of the crystal oscillator, and the average temperature at that time or the crystal oscillator The frequency deviation of the oscillation frequency is stored as the parameter. This makes it possible to correct the time delay based on the frequency deviation of the oscillation frequency of the crystal resonator, which is directly reflected in the adjustment amount by the frequency adjusting unit, and to realize a more accurate time measuring operation.

  The temperature correction table is composed of a plurality of data tables based on setting timings and parameters determined for each region, and the data table corresponding to the region where the electronic timepiece device is installed is referred to by the correction value setting unit. It may be selected as a table.

  An electronic apparatus according to the present invention includes any one of the above-described electronic timepiece devices, and operates based on the date and time counted by the electronic timepiece device.

  The control system of the present invention includes any one of the above-described electronic timepiece devices, and each device constituting the system operates based on the date and time counted by the electronic timepiece device.

  According to the present invention, since the annual setting timing is determined based on the adjustment amount in the frequency adjustment unit, it is not necessary to store the setting timing in which the temperature difference is small and the adjustment amount by the frequency adjustment unit does not change, and the temperature correction table. Storage capacity can be minimized. In addition, when determining the set timing for the year based on the frequency deviation of the oscillation frequency of the crystal oscillator, the frequency deviation of the oscillation frequency of the crystal oscillator is directly reflected in the adjustment amount by the frequency adjustment unit. High timing operation can be realized.

<Configuration of electronic clock device>
The configuration of the electronic timepiece device of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the internal configuration of the electronic timepiece device of the present invention.

  An electronic timepiece device 1 shown in FIG. 1 includes an oscillator 11 having a tuning fork type crystal oscillator 11 a, a frequency divider 12 that divides the frequency of a clock signal output from the oscillator 11, and a frequency divider 12. A clock unit 13 that counts the date and time by the clock signal, a correction value setting unit 14 that sets a correction value based on the date and time clocked by the clock unit 13, and a correction value or surroundings set by the correction value setting unit 14 A temperature correction table 15 that stores the temperature based on the date and time, and a frequency adjustment unit 16 that adjusts the oscillation frequency by the oscillator 11 and the frequency division ratio by the frequency divider 12 are provided.

  In the electronic timepiece device 1 configured as described above, the oscillator 11 generates a clock signal to be a rectangular wave based on an oscillation signal with a reference oscillation frequency obtained by the oscillation of the tuning fork type crystal oscillator 11a, and divides the frequency. To the device 12. The frequency divider 12 divides the frequency of the clock signal input from the oscillator 11 to generate a clock signal (time signal) having a time measuring frequency, and outputs the clock signal to the time measuring unit 13. The tuning-fork type crystal oscillator 11a, the oscillator 11, and the frequency divider 12 constitute a “time signal generator”. The timer 13 measures the date and time by counting in synchronization with the pulse of the clock signal from the frequency divider 11. Thus, the electronic timepiece device 1 can output the current date and time when the oscillator 11, the frequency divider 12, and the time measuring unit 13 operate.

  Further, the date and time measured by the time measuring unit 13 is sent to the correction value setting unit 14, and the correction value setting unit 14 sets correction values for the oscillation operation by the oscillator 11 and the frequency division operation by the frequency divider 12. Timing is confirmed. That is, the correction value setting unit 14 to which the date and time counted by the time measuring unit 13 is given is compared with the date and time stored in the temperature correction table 15 and determines whether or not it is time to switch the correction value. When the correction value setting unit 14 confirms that the date and time counted by the timing unit 13 matches one of the dates and times stored in the temperature correction table 15, the correction value setting unit 14 stores the date and time matched with the date and time in the temperature correction table 15. Reads ambient temperature or correction value. At this time, when the device ambient temperature is stored in the temperature correction table 15, the correction value setting unit 14 calculates a correction value based on the temperature difference between the read ambient temperature and the reference temperature (approximately 25 degrees). .

  As the correction value obtained by the correction value setting unit 14, for example, the frequency deviation (unit: ppm) of the oscillation frequency of the tuning fork crystal resonator is used. The outline of the temperature characteristic of the oscillation frequency in the tuning fork type crystal oscillator 11a is shown in the graph of FIG. As shown in the graph of FIG. 2, in the graph of FIG. 2, the horizontal axis indicates the temperature, and the vertical axis indicates the frequency deviation of the oscillation frequency. As shown in the graph of FIG. 2, in the temperature characteristics of the oscillation frequency in the tuning fork type crystal oscillator 11a, the frequency deviation increases in a negative direction as a quadratic function as the ambient temperature moves away from about 25 degrees. In other words, the oscillation frequency of the tuning-fork type crystal oscillator 11a decreases as the ambient temperature moves away from about 25 degrees, and therefore, when the frequency of the clock signal output to the time measuring unit 13 is not adjusted, the time delay in the time measuring unit 13 is two. It increases in a functional manner.

  When the correction value setting unit 14 acquires a correction value based on the frequency deviation corresponding to the ambient temperature, the correction value is given to the frequency adjustment unit 16. The frequency adjusting unit 16 to which the correction value is given determines the oscillation timing of the oscillator 11 and the frequency dividing ratio of the frequency divider 12 according to the correction value, and the clock signal output from the frequency divider 12 to the time measuring unit 13. Adjust the frequency. That is, the frequency adjustment unit 16 increases the frequency of the clock signal output from the frequency divider 12 by the frequency deviation corresponding to the ambient temperature as the ambient temperature is farther from the reference temperature. The oscillation timing and the frequency division ratio of the frequency divider 12 are adjusted. Thereby, the influence by the oscillation frequency of the tuning fork type crystal oscillator 11a which becomes low based on the ambient temperature can be suppressed, and the time delay in the time measuring unit 13 can be prevented.

<First configuration example of temperature correction table>
A first configuration example of the temperature correction table 15 in the electronic timepiece device 1 configured as described above will be described with reference to FIG. In the temperature correction table of FIG. 3, correction value setting timings (daily or weekly) determined based on the average temperature for one day are stored throughout the year. In the following description, it is assumed that the temperature correction table stores the correction value setting timing in units of days. Further, the temperature correction table 15 in FIG. 3 shows an example configured based on a one-year temperature change in an area where the maximum temperature is T0 + 2 × ΔT and the minimum temperature is T0-3 × ΔT. is there. When the weekly setting timing is stored, the correction value setting timing may be stored based on the average temperature for one week.

As shown in FIG. 3, in the temperature correction table 15, the day when the reference temperature T0 at which the frequency deviation becomes 0 is stored as DA0, and the date when the correction value is set every time the ambient temperature changes by ΔT. DA1 to DA11 are stored. That is, the ambient temperature is higher than the previous set timing by ΔT, such as day DA1 when ambient temperature T0 + ΔT, day DA2 when ambient temperature T0 + 2 × ΔT, day DA3 when ambient temperature T0 + ΔT, or the like. The day when it becomes lower is stored as the next set timing. In the example shown in FIG. 3, in the temperature correction table 15, −α × (m × ΔT) ² (α: coefficient, m: 0 ≦ m ≦ 3) as a frequency deviation for each of the set timings DA0 to DA11. Is stored). That is, the frequency deviation −α × (m × ΔT) ² is stored for the ambient temperature T0 ± m × ΔT.

  As shown in FIG. 3, when the setting timing, the ambient temperature, and the frequency deviation are stored in the temperature correction table 15, the correction value setting unit 14 sets the date DA <b> 0 to DA <b> 0 whose date and time measured by the timer unit 13 is the setting timing. When it is confirmed that it matches any of DA11, the ambient temperature or frequency deviation with respect to the matching setting timing is read. At this time, when reading the ambient temperature from the temperature correction table 15, the correction value setting unit 14 calculates a frequency deviation due to the ambient temperature as a correction value and sends it to the frequency adjustment unit 16. On the other hand, when the correction value setting unit 14 reads the frequency deviation from the temperature correction table 15, the read frequency deviation is sent to the frequency adjustment unit 16 as a correction value.

<Second Configuration Example of Temperature Correction Table>
A second configuration example of the temperature correction table 15 in the electronic timepiece device 1 configured as described above will be described with reference to FIG. In the temperature correction table of FIG. 4, correction value setting timings (daily or weekly) determined based on the frequency deviation due to the average temperature for one day are stored throughout the year. In the following description, it is assumed that the temperature correction table stores the correction value setting timing in units of days. Further, the temperature correction table 15 in FIG. 4 is similar to the above-described first example (see FIG. 3). The temperature for one year in the region where the maximum temperature is T0 + 2 × ΔT and the minimum temperature is T0-3 × ΔT. The example comprised based on a change is shown. When the weekly setting timing is stored, the correction value setting timing may be stored based on the frequency deviation due to the average temperature for one week.

As shown in FIG. 4, the temperature correction table 15 stores the day when the reference temperature T0 at which the frequency deviation becomes 0 is stored as DB0, and the date when the correction value is set every time the frequency deviation changes by ΔK. DB1 to DB25 are stored. That is, the ambient temperature T0 + β ^{(ΔK) 1/2} which days DB1, ambient temperature ^{T0 + β (2 × ΔK)} 1/2 which days DB2, ambient temperature ^{T0 + β (3 × ΔK)} 1/2 which days DB3, · · As shown in FIG. 5, the day when the frequency deviation is higher or lower by ΔK than the previous setting timing is stored as the next setting timing. In the example illustrated in FIG. 4, −n × ΔK (α: coefficient, n: integer of 0 ≦ n ≦ 9) is stored in the temperature correction table 15 as a frequency deviation for each of the setting timings DB0 to DB25. Is done. That is, the frequency deviation −n × ΔK is stored for the ambient temperature T0 ± β (n × ΔK) ^1/2 .

  As shown in FIG. 4, when the setting timing, the ambient temperature, and the frequency deviation are stored in the temperature correction table 15, the correction value setting unit 14 uses the date DB 0 to the date DB <b> 0 to 0 when the date and time counted by the timer unit 13 is the setting timing. When it is confirmed that it matches any of the DBs 25, the ambient temperature or the frequency deviation with respect to the matching setting timing is read out. At this time, as in the first example described above, when reading the ambient temperature from the temperature correction table 15, the correction value setting unit 14 calculates the frequency deviation due to the ambient temperature as a correction value and sends it to the frequency adjustment unit 16. To do. On the other hand, when the correction value setting unit 14 reads the frequency deviation from the temperature correction table 15, the read frequency deviation is sent to the frequency adjustment unit 16 as a correction value.

  Although the temperature correction table 15 having the configuration shown in FIG. 3 or FIG. 4 is exemplified for one region, it may be configured by a data table having a configuration corresponding to a plurality of regions. At this time, the temperature correction table 15 includes a table having the configuration shown in FIG. 3 or 4 for each region. At this time, the electronic timepiece device 1 is designated from the temperature correction table 15 by designating the area where the electronic timepiece device 1 is installed by operating an operation unit (not shown) or receiving a signal by a communication unit (not shown). A data table corresponding to the selected region is selected. Since the correction value setting unit 14 sets the correction value based on the data table selected from the temperature correction table 15 as described above, the frequency adjustment unit 16 changes the temperature according to the installation area of the electronic timepiece device 1. Corresponding adjustment operation is performed.

  As a first embodiment of the present invention, an embodiment in which the above-described electronic timepiece device is provided in a program timer device will be described and described below with reference to the drawings. FIG. 5 is a block diagram showing a configuration of a control system having a program timer device in the present embodiment. FIG. 6 is a block diagram showing an internal configuration of the program timer apparatus in the control system of FIG. In addition, as a control system shown in this embodiment, a control system based on a time division multiplex transmission method that transmits and receives signals by a time division multiplex transmission method using the signal line Ls will be described as an example. However, the control system such as RS232C or RS485 is described. A control system using a bidirectional communication system or a control system using a local area network (LAN) using Ethernet (registered trademark) may be used.

  The control system shown in FIG. 5 includes a program timer device 3 that stores each control content for performing time schedule control, an input terminal device 4 that receives an input of control content of the load device 6, and the load device 6. The load terminal device 5 that controls the operation is connected to the transmission control device 2 via the signal line Ls. At this time, when the load device 6 is an illuminator and the control content stored in the program timer device 3 or the control content received by the input terminal device 4 is ON / OFF of the load device 6, the load terminal device 5 is constituted by a relay switch for turning on / off the power to the load device 6 and a relay control device for giving a control signal to the relay switch.

  A time division multiplexed signal transmitted and received by the time division multiplexing transmission method in this control system will be briefly described. The transmission control device 2 transmits a time division multiplexed signal including a control signal and a dummy signal described later. The time division multiplexed signal transmitted from the transmission control device 2 includes a synchronization pulse, mode data indicating a signal mode, a terminal device (program timer device 3, input terminal device 4, And address data indicating the address (equivalent to the load terminal device 5) (8 bits), control data indicating the control content, checksum data for detecting a transmission error, and a return signal from the terminal device. Each data is formed by pulse width modulation.

  The time division multiplex signal transmitted from the transmission control device 2 functions as constant polling transmitted at regular intervals. And when transmitting the time division multiplexing signal used as a control signal to the terminal device which becomes a communication partner, the control data according to the control content is incorporated in the time division multiplexing signal together with the address data. When the transmission control device 2 does not need to transmit a control signal, the transmission control device 2 uses the dummy mode mode data indicating the permission of interruption and the synchronization pulse to accept the interruption from the terminal device. The configured time division multiplexed signal is transmitted as a dummy signal.

  On the other hand, when the terminal device interrupts, when receiving a dummy signal from the transmission control device 2, the terminal device indicates that the own device performs an interrupt in order to respond synchronously to the synchronization pulse of the dummy signal. An interrupt signal is generated, and this interrupt signal is returned to the transmission control device 2. At this time, since the transmission control device 2 that has received the interrupt signal recognizes that there is an interrupt from the terminal device, when transmitting the next time division multiplexed signal following the dummy signal to which the interrupt signal is synchronized, An interrupt polling signal in which the mode data is set to the interrupt polling mode is transmitted. This interrupt polling signal is repeatedly transmitted by increasing the upper bits of the address data in order until there is a reply from the terminal device that transmitted the interrupt signal.

  After that, when the terminal device that requested the interrupt receives the interrupt polling signal having the address data that matches the upper bit of the address, the lower bit of the address of the own device is replaced with the signal return period of the interrupt polling signal. Is sent back to the transmission control device 2 as monitoring data. When the transmission control device 2 receives the monitoring data, the transmission control device 2 acquires the address of the terminal device that requested the interruption from each of the address data of the interruption polling signal and the monitoring data. Therefore, the transmission control device 2 generates a control signal based on the address data based on the acquired address, transmits the mode data as the monitoring mode, and then returns from the terminal device that requested the interrupt. Receive data.

  And the transmission control apparatus 2 recognizes the content of the information transmitted from a terminal device by processing the monitoring data from a terminal device. For example, if the terminal device that requested the interrupt is the program timer device 3, the program timer device 3 monitors the address and control content of the terminal device that is the control partner during the signal return period of the control signal in the monitoring mode. Data is returned to the transmission control device 2. Thereby, the transmission control apparatus 2 can instruct | indicate a predetermined | prescribed control operation with respect to a predetermined | prescribed terminal device at the predetermined time by interruption operation | movement of the program timer apparatus 3.

  As shown in FIG. 6, the program timer device 3 in such a control system is connected to a two-wire signal line Ls to acquire power, and connected to the signal line Ls to transmit control described later. Each of the operations of the communication unit 32 that transmits and receives signals to and from the device 2, the clock unit 33 that measures the date and time, the address setting unit 34 that stores the address set in the program timer device 3, and the program timer device 3 A liquid crystal display for displaying a signal processing unit 35 for performing signal processing, an input key 36 for receiving an input from the outside, a current time measured by the clock unit 33, an input content received by the input key 36, and the like. Unit 37.

  Such a program timer device 3 has a configuration in which the electronic timepiece device 1 of FIG. 1 is incorporated. Therefore, the tuning fork crystal oscillator 11a, the oscillator 11, the frequency divider 12, the time measuring unit 13, and the frequency adjusting unit 16 (see FIG. 1) constitute a clock unit 33 and a signal processing unit 35, As a part, a functional part by the correction value setting part 14 and the temperature correction table 15 (refer FIG. 1) is provided. Therefore, since the program timer device 3 has a configuration in which the electronic timepiece device 1 shown in FIG. 1 is incorporated therein, it is possible to prevent a time delay in the timepiece unit 33 and to measure an accurate date and time.

  In the program timer device 3, when the input key 36 is operated, the control content and control time of each load device 6 in the control system are input and stored in the signal processing unit 35. When the signal processing unit 35 recognizes that the stored control time has been reached based on the current time measured by the clock unit 33, the signal processing unit 35 and the load device 6 to be controlled with respect to the control time Read the control contents. At this time, the signal processing unit 35 generates monitoring data to be sent back to the transmission control device 2 based on the address data specifying the load terminal device 5 that controls the load device 6 to be controlled and the control content. To do.

  In other words, when the stored control time is reached, the communication unit 32 transmits an interrupt signal in synchronization with the dummy signal from the transmission control device 2. After that, after returning to the interrupt polling signal in which the address data is configured by the higher-order bits of the address stored in the address setting unit 34, when the control unit further receives a control signal, the control content to be controlled at the achieved control time Then, monitoring data composed of address data specifying the load terminal device 5 is generated, and the monitoring data is returned from the communication unit 32 to the transmission control device 2.

  Therefore, the transmission control device 2 can recognize the address of the load terminal device 5 to be controlled and the control content at the preset time by the interruption of the program timer device 3. Then, the transmission control device 2 generates a control signal based on the address data of the load terminal device 5 recognized by the interruption of the program timer device 3 and the control data indicating the control content, and from the signal line Ls, It transmits to the target terminal device 5 for load. By operating in this way, the time schedule control set by the program timer device 3 is realized, so that the predetermined load device 6 can be operated at a predetermined operation at a predetermined time.

  The present invention can be applied to an electronic device including an electronic timepiece device that performs a timekeeping operation using a crystal oscillator, or a control system or a management system in which such an electronic device is incorporated.
