  The detection value display unit 96 also displays the upper limit (Th (H)) and lower limit (Th (L)) of the threshold value of the rotation speed. Thereby, the operator can grasp the operation status in more detail by comparing the threshold value and the detection value. When the operator operates the “return” 97 button displayed on the screen 76a, the processing / calculation unit 71 switches the display to the operation status management data 80 shown in FIG.

  Next, with reference to FIG. 9, the drying chamber data 100 which is a kind of operation data displayed on the screen 76a of the monitor 76 will be described. Here, description will be limited to drying room data 100 related to temperature. The drying room data 100 is created by the data creation unit 73. In addition to the above-described “user ID” 101 and “device ID” 102, “address” 103, “abnormality” 104, “other address” 105, detection value display unit. 106 is comprised.

  “Address” 103 indicates a detection position set in the drying chamber 31. The “abnormality” 104 visually notifies the presence / absence of abnormality of the detected temperature value at the detection position to be displayed. “Other address” 95 indicates another detection position set in the drying chamber 31. When the operator operates a button on which a predetermined address is displayed, the processing / calculation unit 71 switches the display target of the monitor 76 to the drying chamber data 100 corresponding to other detection positions.

  The detection value display unit 106 visually displays a change in the detection value of the temperature at the detection position to be displayed in time series, and the elapsed time since the operation in the drying chamber 31 is started on the horizontal axis. A graph format is adopted in which (min) is associated and the detected value (° C.) of the temperature is associated with the vertical axis. For example, when the display target is the first detection position R1, the detection value by the first temperature sensor 48A installed corresponding to the position is displayed. The horizontal axis may correspond to the quantity of raw seaweed w transported through the drying chamber 31, and the display mode and graph format are arbitrary. Further, the drying room data 100 relating to humidity corresponds to data obtained by replacing the above-mentioned “temperature” and “temperature sensor 48” with “humidity” and “humidity sensor 49”. Furthermore, a graph representing changes in temperature and humidity at a predetermined detection position may be displayed on the same detection value display unit 106 in an overlapping manner. As described above, the data creation unit 73 creates the drying chamber data 100 that indicates the change in temperature or humidity in the drying chamber 31 in time series based on each value detected by the temperature sensor 48 or the humidity sensor 49 as operation data. .

  By visually recognizing the drying chamber data 100 described above, the operator can visually grasp the transition of the temperature change (or humidity change) at a predetermined position in the drying chamber 31. Furthermore, since the detected value display unit 106 also displays the upper and lower limits of the temperature threshold value, the operator can grasp the operating status in more detail by comparing the threshold value and the detected value. When the operator operates the “return” 107 button displayed on the screen 76a, the processing / calculation unit 71 switches the display to the operation status management data 80 shown in FIG.

  The dry seaweed manufacturing system in the present embodiment is configured as described above. Next, the flow of the abnormality determination process by the abnormality determination unit 74 will be described with reference to FIG. First, the abnormality determination unit 74 determines whether or not the management computer 3 has received operation information from any of the connected dry laver production apparatuses 2 (ST1: reception presence determination step). When it is determined that it has been received in (ST1) (“Yes” in (ST1)), the abnormality determining unit 74 includes the identification information of the dry seaweed manufacturing apparatus 2 in the operation information, the detection value by the rotation speed detection unit 63, and the drying chamber. The number of raw seaweed w transported 31 and the detected values by each temperature sensor 48 and humidity sensor 49 are read (ST2: operation information reading step).

  Next, the abnormality determination unit 74 reads the abnormality determination data 79 corresponding to the dry laver manufacturing apparatus 2 that has read the operation information (ST3: abnormality determination data reading step). Next, the abnormality determination unit 74 compares the read operation information with the abnormality determination data 79 and determines whether or not the detected predetermined value is within a threshold range defined in the corresponding abnormality determination data 79 ( ST4: Determination step).

  For example, when the determination target in (ST4) is the drive motor 18, the abnormality determination unit 74 defines the value of the rotation speed of the shaft of the drive motor 18 detected by the rotation number detection unit 63 in the abnormality determination data 79. It is determined whether the rotational speed of the shaft of the drive motor 18 is within the threshold range. Then, the abnormality determination unit 74 determines “abnormal” when the detected value of the rotational speed is outside the threshold value range. That is, the abnormality determination unit 74 has a predetermined number of rotations of the predetermined drive motors 18, 26, 36, 43, 51, 52, 53 at a predetermined time point transmitted from the dry seaweed manufacturing apparatus 2, and a predetermined drive motor 18 set in advance. , 26, 36, 43, 51, 52, 53, the presence or absence of abnormality of the drive motors 18, 26, 36, 43, 51, 52, 53 is determined.

  In addition, when the determination target in (ST4) is the temperature at the first detection position, the abnormality determination unit 74 has the detection value detected by the first temperature sensor 48A within the threshold range defined in the abnormality determination data 79. Determine whether. Then, the abnormality determination unit 74 determines “abnormal” when the detected value is outside the threshold value range. The above determination is the same for humidity. That is, the abnormality determination unit 74 determines the presence or absence of abnormality in the drying chamber 31 based on each temperature or humidity value detected by the temperature sensor 48 or the humidity sensor 49 and a preset temperature or humidity threshold. .

  When it is determined that the predetermined detection value to be determined is outside the threshold range (“No” in (ST4)), the abnormality determination unit 74 determines that there is an abnormality in the operation data with respect to the data creation unit 73. A signal requesting reflection of information indicating the result is output (ST5: request signal output step). In this step (ST5), the abnormality determination unit 74 also outputs a signal requesting the operation of the buzzer 78 to the processing / calculation unit 71. In response to the signal output from the abnormality determination unit 74, the data creation unit 73 rewrites the determination result in the operation data with abnormality. Further, the processing / calculation unit 71 controls the buzzer 78 to notify the operator. That is, the processing / calculation unit 71 and the buzzer 78 function as a notification unit that notifies when the abnormality determination unit 74 determines that an abnormality has occurred.

  When it is determined in (ST4) that the predetermined detection value to be determined is within the threshold range (“Yes” in (ST4)), the abnormality determination unit 74 determines whether there is another detection value to be determined. (ST6: determination target presence / absence determination step). If there is another detection value to be determined (“Yes” in (ST6)), the process returns to (ST4). If there is no other detection value to be determined (“No” in (ST6)), the process returns to (ST1).

  As described above, according to the dry seaweed production system 1 in the present embodiment, the management computer 3 generates operation data indicating the operation status of the dry seaweed production apparatus 2 based on the operation information transmitted from the dry seaweed production apparatus 2. Since the data creation unit 73 to be created and the display unit (monitor) for displaying the operation data created by the data creation unit 73 are included, when the user reports that the dry seaweed manufacturing apparatus 2 is in trouble, The contacted operator can quickly find out the cause without having to go directly to the user, and can quickly eliminate the trouble and labor of the operator and solve the problem of the dry seaweed production apparatus 2 It can be carried out. As a result, the dry seaweed production apparatus 2 can be restarted promptly and a decrease in productivity can be suppressed. In particular, the present invention can quickly solve the cause of a problem even for an inexperienced manufacturer operator. It is extremely useful in that it can be investigated.

  The present invention is not limited to the embodiments described so far and can be appropriately changed without departing from the spirit of the invention. For example, the drive target by each drive motor is arbitrary, and a drive motor may be provided for each drive target. The operation data displayed on the monitor 76 may have any other configuration as long as at least the detection target and the detected value are displayed on the same screen. Instead of the notification by the buzzer, the processing / calculation unit 71 may be configured to notify the operator with a configuration in which the monitor 76 visually displays information indicating that there is an abnormality. In this case, the processing / calculation unit 71 and the monitor 76 constitute a notification unit. Further, the first temperature sensor 48A and the first humidity sensor 49A, and the second temperature sensor 48B and the second humidity sensor 49B may be arranged in different positions in the drying chamber 31.

  INDUSTRIAL APPLICABILITY According to the present invention, the cause of a problem occurring in a dry seaweed production apparatus can be quickly and easily investigated, and a reduction in productivity can be prevented, which is useful in the dry seaweed production field.
