Description

        The present invention is a recorder capable of facilitating the setting of an alarm value for issuing an alarm by manually moving an alarm pointer that slides on a scale plate in the alarm setting of the recorder. Further, the present invention is a recording meter characterized in that an upper limit value and a lower limit value can be set by providing two pointer detection sensors for detecting the position of the pointer in the alarm pointer.

Generally, a recorder that records on recording paper based on an input signal performs A / D conversion on a signal input from a sensor such as a temperature sensor, calculates an input value after performing arithmetic processing. Yes. In the case of a recorder having a pointer, the pointer slides on the scale plate based on the calculated input value.
When setting an upper limit alarm or lower limit alarm for an input value in a conventional analog recorder, the alarm setting can be intuitively set in real time by moving the alarm pointer on the scale plate in real time while continuing recording. Is possible. However, the size of the dead zone is determined by the performance of the switch element (for example, a micro switch), and in a recorder capable of inputting a plurality of channels, there arises a problem that the dead zone state of the previous channel is inherited. .

Currently, in digital recorders with general guidelines, when setting an upper limit alarm or lower limit alarm for an input value, a display that can visually recognize the set value, such as a display, and a set value are displayed from a dedicated setting mode. Generally, the setting is performed using a keyboard capable of inputting.
In addition, in a digital recorder having a general pointer that does not have a display whose setting value is visible, such as a display device, a pointer portion that can read the input value and a keyboard that can operate the pointer portion are used. It is common to set an alarm value.

Japanese Patent Application No. 10-68641

However, in the case of such a digital recorder, since the alarm value is set as a digital value, the intuition is low, and an operation for appropriately moving the alarm value sensuously cannot be performed.
Also, in the case of a digital recorder that has a pointer that does not have a display whose setting value is visible, such as an indicator, the alarm setting value cannot be changed during recording. It is necessary to temporarily stop recording and reset the alarm setting value.

On the other hand, in the conventional analog recorder, the state of the previous channel was taken over in the dead zone when the channel was changed, and there was a case where the alarm could not be issued correctly. Specifically, as shown in the example of FIG. 6, in the two-dot analog recorder, CH1 and CH2 are in an instruction state lower than the alarm point (state (a)), and the instruction of CH1 rises. In the state of (b), CH1 indicates the dead zone, but no warning is issued because it is lower than the alarm point. Next, when the channel is changed to CH2 and the instruction of CH2 becomes higher than the alarm point, the state (c) is entered and an alarm is issued. Then, when the channel is changed from CH2 to CH1 again, and the state of (d) is reached, the instruction of CH1 indicates a value lower than the alarm point in the dead body region, as in the state of (b). for, for thereby holding the state of the previous channeling Le alarm from being alarm.

In view of the above problems, the present invention provides the following recorder. As a first invention, in a recorder that records input signals input from a plurality of input channels on a recording sheet at predetermined intervals, a recording unit that records on the recording sheet based on the input signal, and a recording unit A recording paper conveying means for conveying the recording paper, a scale plate arranged in a direction orthogonal to the conveyance direction of the recording paper, a pointer that slides along the scale plate based on an input signal, and the scale plate The alarm pointer that can be manually slid and set the alarm alert value, and a plurality of alarm pointers are arranged so as to set a dead zone in a predetermined area before and after the alarm indicator. and guidelines detection sensor for detecting whether a storage unit in which the input signal from the preceding cycle of the input channels are stored whether exceeds the alarm onset report value, the pointer detection sensor in the cycle is that the pointer the In the dead zone area Upon detection of a, to provide a recorder that has the information stored in the storage unit, a determination unit for determining whether to alarm an alarm, a.

      As a second invention, the alarm pointer includes a first alarm pointer that sets an upper limit value of the pointer, and a second alarm pointer that sets a lower limit value of the pointer. Provide a total.

<Embodiment 1>
<Overview of Embodiment 1>
In the present embodiment, the movement of the pointer sliding on the scale plate is detected by an alarm pointer having two or more pointer detection sensors, the presence / absence of an alarm notification in the previous input channel and the detection result of the pointer The recorder is configured to determine whether or not to issue an alarm. The alarm setting can be set by manually moving an alarm pointer that slides on the scale plate even during recording.

<Configuration of Embodiment 1>
FIG. 1 is a conceptual diagram for explaining the recorder of the present embodiment. The recorder of the present embodiment includes a recording unit (0101) that records input signals input from a plurality of input channels on a recording sheet at predetermined intervals, and that records on the recording sheet based on the input signals. In the recording unit, based on the input signal along the scale plate, the recording paper transport means (0102) for transporting the recording paper, the scale plate (0103) arranged in the direction orthogonal to the transport direction of the recording paper, A sliding pointer (0104), an alarm pointer (0105) that can be manually slid on the scale plate and set an alarm alarm value, and a plurality of alarm pointers are arranged on the alarm pointer. A pointer detection sensor for detecting whether or not the value exceeds the value, a storage unit for storing whether or not the input signal from the input channel one cycle before exceeds the warning value, and the pointer detection sensor in the cycle Detection results and From serial stored in the storage unit information has a determining section for determining whether to alarm an alarm. Note that the storage unit and the determination unit are configured by circuits such as a CPU, a main memory, and a flash memory, and thus are not shown in FIG. The pointer detection sensor is not shown in FIG. 1 because it corresponds to the back surface of the scale plate.

    The “recording unit” records on the recording paper based on the input signal input to the recorder. For this reason, the recording unit has a recording paper transporting unit, which will be described later, and a pen, a plotter, etc. for performing printing and drawing on the recording paper. Further, the recording unit may be configured to record on an electronic recording medium such as a hard disk or a flash memory in addition to paper.

    The “recording paper transport unit” transports the recording paper in a certain direction in the recording unit. The recording paper conveyance direction of the recording paper conveyance means is a direction orthogonal to the printing and drawing directions of the pen and plotter that perform recording on the recording paper described above.

The “scale plate” is arranged in a direction perpendicular to the conveyance direction of the recording paper conveyance means, and a pointer described later indicates the scale on the scale plate and slides. Further, the scale on the scale plate functions as a scale for setting an alarm alert value of an alarm pointer to be described later. When setting the alarm alert value, manually operate the alarm pointer and set the alarm set value using the scale on the scale plate as a guide.

    The “pointer” slides along the scale plate based on the input signal. More specifically, it operates along the scale plate in accordance with the movement of a printing unit such as a pen or a plotter that records on the recording paper in the recording unit. In addition, when a plurality of pointer detection sensors provided on an alarm pointer, which will be described later, is a photo interrupter, the pointer is provided with a shielding plate that blocks an optical path so that the photo interrupter can detect the pointer. In addition, a configuration for detecting the pointer may be provided in accordance with the detection unit of the pointer.

  The “alarm pointer” is manually moved on the scale plate to set an alarm alert value. For example, when the user of the recorder of the present embodiment wants to set an alarm with an arbitrary value, the alarm pointer is manually slid to the scale on the scale plate and set. That's fine. This alarm pointer is provided with a pointer detection sensor which will be described later, and is configured to issue an alarm when the pointer detects that the alarm alarm value set by the alarm pointer has been exceeded. Yes.

    The alarm pointer and the pointer are configured to move along the same common scale plate, but are arranged on different slide shafts and operate independently without interfering with each other. It is configured to be possible.

    A plurality of “pointer detection sensors” are arranged on the above-described alarm pointer, and detect whether or not the pointer exceeds an alarm alert value. An example in which a photo interrupter is used as a pointer detection sensor will be described with reference to FIG. (A) is an enlarged view of the scale plate (0201), pointer (0202), alarm pointer (0203), and pointer detection sensor (photo interrupter) (0204) of the recorder shown in FIG. It is a conceptual diagram. In addition, (a) is a see-through | perspective conceptual diagram when seeing through a scale plate for description. As described above, the pointer and the alarm pointer are configured to slide on the scale plate so as not to interfere with each other. (B) is an enlarged view of the warning pointer in (a) and partially seen through. The alarm pointer on the back side of the scale plate has a main body of the alarm pointer, and the main body of the pointer is connected to an axis (0207) parallel to the scale plate. A photo interrupter is provided on the bottom side of the main body of the alarm pointer. The photo interrupter has a light emitting means and a light receiving means, and an optical path is provided between the light emitting means and the light receiving means. This photo interrupter is enlarged (c). The object is detected by blocking the optical path (0205) of the photo interrupter. Next, (d) is an enlarged view of the pointer (a). The pointer on the back side of the scale plate has a main body of the pointer, and the main body of the pointer is connected to an axis (0208) parallel to the scale plate. On the upper surface side of the pointer main body, a shielding plate (0206) is provided to block the optical path of the photo interrupter provided on the bottom surface side of the alarm pointer main body described above. The shielding plate provided on the pointer moves in accordance with the movement of the pointer and blocks the optical path of the photo interrupter, so that the pointer detection sensor determines whether or not the pointer exceeds the set alarm alert value. .

The recorder of the present embodiment, the photo-interrupter comprising this guide detection sensor is a plurality placed. Therefore, the actual configuration is as shown in FIG. As shown in FIG. 3A, a plurality (two in the figure) of photo interrupters (0302 and 0303) are arranged in the direction perpendicular to the scale plate (0304) on the bottom surface side of the alarm pointer (0301). Has been. The photo interrupter is installed so that the optical path (0305, 0306) is in a direction perpendicular to the scale plate. Further, on the upper surface of the main body of the pointer (0307), shielding plates (0308, 0309) that block the optical path of the photo interrupter are arranged in the same number (two in the drawing) as the number of photo interrupters.

FIG. 3B is a conceptual diagram showing the bottom side of the main body of the alarm pointer shown in FIG. The photo interrupters arranged on the bottom side of the alarm pointer main body are arranged side by side in a direction orthogonal to the scale plate. At this time, the plurality of photo interrupters are arranged offset in a direction parallel to the scale plate. On the other hand, the several shielding board provided in the main body of the pointer | guide is arrange | positioned in the position aligned in the direction orthogonal to a scale plate. By arranging the photo interrupters in an offset manner in this way, a plurality of photo interrupters, that is, ON and OFF of the detection sensors do not occur at the same time, and it is possible to set a dead zone region by occurring at shifted timings. Become. Note that the dead zone area is a predetermined area before and after the alarm pointer, and is an area in which the alarm state in the previous cycle is continued when the pointer indicates the dead zone area. When a recorder is actually used, depending on the input signal that is input to the recorder, the alarm relays frequently, for example, the pointer moves up and down around the value indicated by the alarm pointer, and the alarm is repeatedly issued or stopped. May be turned ON or OFF. In particular, when the relay is a mechanical relay, it may cause a failure of the recorder such as contact welding. In addition, there is a possibility of affecting not only the recorder but also a device connected to the recorder. Therefore, when instructed in this dead zone, it is possible to avoid such a problem by continuing the alarm state of the previous cycle and not performing the alarm determination. As a specific example, an example is shown in which the photo interrupter is arranged offset and the shielding plate is arranged at the same position. Conversely, the photo interrupter is arranged at the same position and the shielding plate is offset. The dead zone region can be set by arranging the dead zone region. In addition, the size of the dead zone can be adjusted by adjusting the arrangement position of the photo interrupter, the size of the shielding plate, and the like. The size of the dead zone region is a design matter that is appropriately determined depending on the type of input signal input to the recorder of the present embodiment.

    As described above, by arranging a plurality of pointer detection sensors on the alarm pointer at positions offset along the scale, it is possible to accurately issue an alarm. The plurality of pointer detection sensors provided in the alarm pointer are not particularly limited to the photo interrupter, and may be any sensor that can detect the position of the pointer in addition to the photo interrupter.

    The “storage unit” is a storage area for storing whether or not the input signal from each input channel in the previous cycle has exceeded the alarm alert value. The information stored in the storage unit is used when a determination unit described later determines whether or not to issue an alarm. When this storage unit is realized as hardware, it is realized by a flash memory or a hard disk storage device.

The “determination unit” determines whether or not the detection result of the pointer detection sensor in the current cycle and the input signal from the input channel one cycle before stored in the storage unit exceed the alarm notification value. It is determined whether to issue an alarm from the information. The determination method of the determination unit will be described with reference to FIG. Note that the example shown in FIG. 4 is a recorder that has two input signals of two channels (CH1 and CH2) and two photo interrupters that are pointer detection sensors. First, in the initial stage, as shown in (a), CH1 is in the vicinity of the alarm alert value from a state in which it is significantly lower than the alarm alert value set by the alarm pointer until one cycle before. In other words, a dead zone area is indicated. The pointer detection sensor 1 is in an ON state (a state where the optical path of the photo interrupter is blocked), and the pointer detection sensor 2 is in an OFF state (a state where the optical path of the photo interrupter is not blocked). At this time, since one of the pointer detection sensors is ON, it is recognized that the pointer is in the dead zone region. In this state, the alarm determination is OFF.

    Next, when switching from CH1 to CH2 is performed from the state of (a), CH2 indicates a position that greatly exceeds the warning pointer as shown in (c), so as shown in (b). In addition, after the pointer detection sensor 1 and the pointer detection sensor 2 are both turned on, the state (c) is obtained. Although the state of (c) greatly exceeds the alarm pointer, both the pointer detection sensor 1 and the pointer detection sensor 2 are in the OFF state. Even in such a case, the recorder of the present embodiment is configured to issue an alarm.

    Furthermore, when the channel of the input signal returns from CH2 to CH1 from the state of (c), the state of (d) is obtained. This state is the same as the state (a) one cycle before. At this time, in the conventional analog type recorder, the state of the CH2 alarm is maintained and the alarm is issued. However, in the recorder of the present embodiment, the CH1 in the previous cycle is stored in the storage unit. The presence / absence of warning is memorized, and the state of (d), which is the detection result of the pointer detection sensor, is the same as the state of (a). It is determined that there is no need to issue an alarm even if

    In the recorder of the present embodiment, in order to determine on which side the pointer is present with respect to the alarm pointer, determination is made based on the timing when the two photo interrupters provided in the pointer detection sensor are turned on and off. Is possible. For example, when the sensor 1 is turned on and the sensor 2 is turned off, the pointer exists in the lower limit side (left side in FIG. 4) of the alarm pointer, and the sensor 1 and the sensor 2 are turned on in this order. Thus, it is detected that the pointer is moving from the lower limit side to the upper limit side of the alarm pointer. When only the sensor 1 is turned OFF from the sensor 1 and the sensor 2 being ON, it is detected that the pointer exists in an area exceeding the alarm pointer on the upper limit side (right side in FIG. 4). Furthermore, when the sensor 1 and the sensor 2 are turned OFF in this order, it is detected that the pointer has moved to the upper limit side of the alarm pointer.

    Conversely, when both sensor 1 and sensor 2 are turned on in the order of sensor 2 and sensor 1, it is detected that the pointer is moving from the upper limit side to the lower limit side of the alarm pointer. The In other words, in the recorder of this embodiment, it is possible to grasp on either side of the alarm pointer on each channel, and whether to issue an alarm based on the detection information of these pointers. It is possible to determine whether or not.

    As described above, in the recorder of the present embodiment, even when the pointer is located in the dead zone, it is possible to correctly issue an alarm. When the determination unit is realized as hardware, the determination unit includes a CPU and a main memory that perform various arithmetic processes, a program that performs various processes and determinations, and the like.
