The cool memory 3 is loaded into a container (recording target) containing refrigerated food such as a lunch box or a beverage delivered to a convenience store, and is used for detecting and recording the temperature of the food. . in this case,
The measurement control unit 148 measures the food temperature (the temperature in the container) at a predetermined sampling cycle (measurement interval) by the sensor unit 149. In this case, the measurement control unit 148 performs A / D conversion of the analog data from the sensor unit 149 to obtain temperature data as measurement data. And
The measurement control unit 148 records the temperature data thus measured together with the time data sent from the clock control unit 141 in three types.

That is, the measurement control unit 148 writes the temperature data into the temperature history memory 146. This temperature history memory 1
The time data calculated from the measurement start date and time and the measurement interval is added to the temperature data in 46 when the personal computer 1 reads the data from the cool memory 3 as described later. Further, the measurement control unit 148 divides the food temperature into zones (for example, a zone of 0 ° C. or lower, a zone of 0 ° C. to + 5 ° C., a zone of + 5 ° C. to + 10 ° C., and a zone of + 10 ° C. to + 15 ° C.).
Zones, zones of + 20 ° C. or higher), and the measured temperature data is distributed to each zone and counted.
A histogram is created and written to the histogram memory 144.

In this case, for example, if the food temperature has become 0 ° C. or less once, the zone below 0 ° C. is set to 1 and 0 ° C.
If it was 100 times that the temperature was + 5 ° C., the zone of 0 ° C. to + 5 ° C. is set to 100.
00, and if it was + 10 ° C. to + 15 ° C. ten times, the zone of + 10 ° C. to + 15 ° C. is set to 10, and + 20 ° C.
If this is the case once, the zone at + 20 ° C. or higher is defined as 1.

The temperature alarm memory 143 records temperature alarm data. In this case, the temperature alarm includes a high-temperature alarm when the temperature exceeds the upper limit of the temperature alarm and a low-temperature alarm when the temperature falls below the lower limit of the temperature alarm. Is done.

When the food is delivered to the store, the cool memory 3 is removed from the container and the button reader 2
To be stored in the storage section 11. As a result, the cool memory 3 is connected to the signal line 17 so that data can be transmitted and received to and from the personal computer 1.

The ID stored in the cool memory 3
The ID code of the cool memory 3 itself and identification data indicating that the memory is the cool memory 3 are written in the unit 133.
A communication protocol 38 for performing data communication with the personal computer 1 is stored in 38. For example, various setting data described later is written in the memory 137.
The memory 138 is a memory that can be used by the user, and the memory 138 stores the memories 143, 144,
Software for displaying the data in 146 on the personal computer 1 may be written in advance, in which case the burden on the personal computer 1 is reduced.

Here, the sensor unit 149 of the cool memory 3
21 is as shown in FIG. 21. If it is assumed that a measurement error as shown in FIG. 21 occurs at each measurement temperature, the measurement error is obtained in advance by an experiment. In a memory 138 as a user memory, measurement error data indicating an error generated at the time of measurement by the sensor unit 149 is written in a data table format in advance.

With the above configuration, a procedure for actually reading data and setting data between the personal computer 1 and the cool memory 3 will be described. First, when starting the operation of reading data from the cool memory 3, the personal computer 1
Start the control program. CR in the subsequent standby state
On the T display 6, a menu bar and tool buttons (not shown) are displayed. Next, when the tool button (not shown) for using the cool memory 3 displayed on the CRT display 6 is clicked with the mouse 9, the CPU 31
The status display screen shown in FIG.

Next, each storage section 11 of the button reader 2
, For example, three cool memories 3... Are mounted, and the "search" frame on the status display screen of FIG.
The CPU 31 scans (searches) the cool memories 3... Connected to the button reader 2.

This scan operation is performed for each of the cool memories 3.
This is performed by reading out the ID code written in the ID section 133 of. The CPU 31 identifies the connection state of the three cool memories 3... Based on the ID codes collected by scanning, temporarily retains these ID codes in the memory 32, and thereafter uses the ID codes to store the respective cool memories 3.・ ・ Send and receive data to and from. Further, the collected ID codes are listed and displayed in the “Cool memory selection” column of the status display screen of FIG.

When the down arrow button of the "Cool memory selection" section is clicked with the mouse 9, the ID codes of the respective cool memories 3,... Searched as shown in FIG. By clicking this ID code, the cool memory 3 for reading and writing data can be selected.

When one of the cool memories 3 connected to the button reader 2 is selected in this manner, the CPU 31 displays the cool memory 3 in the “operating state” frame on the display screen of FIG.
Displays the operating status of. At this time, the CPU 31 polls the selected cool memory 3 and requests transmission of various setting data relating to the operation of the cool memory 3.

The memory control unit 136 of the cool memory 3
The memory 137 in response to the polling from the personal computer 1
Setting data and clock control unit 14 written in the
1 is transmitted to the personal computer 1 by the interface 132 via the signal line 17.

The CPU 31 of the personal computer 1 is a cool memory 3
After temporarily writing the data transmitted from the memory 32 to the memory 32, the operating state of the cool memory 3 is displayed in the “operating state” frame of the state display screen of FIG. In this case, the CPU 31 displays whether the cool memory 3 is currently operating or stopped in the “operating state” column of the “operating state” frame.

The "remaining standby time" column displays the remaining standby time until the temperature measurement is started, and the "measurement start time" column displays the temperature measurement start date and time. In the “Measurement interval” column, the interval of temperature measurement (sampling cycle) is displayed. In the “Measurement data number” column, the total number of data measured since the start of the measurement is displayed. The “number of data” column displays the number of data stored in each memory 146.

Further, the "memory overwrite" column displays a setting state of whether new data is overwritten (or not) when the data amount of each memory is saturated. In other words, when "overwrite" is set, when the data amount becomes full, old data is discarded and new data is written, and when "no" is set, it becomes full. At this point, the cool memory 3 stops the recording operation. In the "memory overwrite occurrence" column, it is displayed whether or not the data in each memory has been overwritten during the measurement (presence / absence).

Further, the upper limit temperature of the temperature alarm is displayed in the "temperature alarm upper limit" column, and the lower limit temperature of the temperature alarm is displayed in the "temperature alarm lower limit" column. In the “current time” column, the time data (date and time) held by the clock control unit 141 of the cool memory 3 is displayed.
The “Total measurement count” column displays the total number of temperature measurements up to the present.

Here, in the temperature measurement by the cool memory 3, the operation which consumes the most power is the A / D conversion in the measurement control unit 148. Therefore, the life of the battery 147 can be determined from the total number of measurements.

That is, assuming that the life of the battery 147 is defined as, for example, 500,000 times in terms of the number of measurable times (actually, it can be used more times).
Depending on whether the total number of measurements displayed in the "total measurement count" column of the RT display 6 is close to or far from this 500,000 times, it is possible to determine how long the cool memory 3 can be used (use limit) later. it can.

When the total number of measurements exceeds, for example, 490,000, the CPU 31 displays the number in the “total measurement count” column in yellow, for example, and further displays 50%.
If the number exceeds 10,000 times, the number is displayed in red, for example, on the CRT.
It is displayed on the display 6. This allows the user to reliably and accurately determine that the life of the battery 147 of the cool memory 3 is nearing the end of its life.

Here, if the cool memory 3 is used in a high temperature environment of, for example, ambient temperature + 50 ° C. or more, the battery 147
Self-discharge may shorten the life. Therefore, the measurement control unit 148 of the cool memory 3
The number of times of the above temperature measurement is written in the memory 138. Then, the CPU 31 stores +5 in the memory 138 of the cool memory 3.
If the number of times of measurement at a temperature of 0 ° C. or more has been written even once, for example, “!” Is displayed adjacent to the number in the “Total measurement count” column.

Thus, the user can accurately recognize that there is a possibility that the cool memory 3 cannot be used for the specified number of 500,000 measurements. It should be noted that other symbols may be used as the display symbols, and the display symbols are not limited to the symbols, and may be identified by display colors. In the “memo” column, predetermined memo contents such as a written measurement point are displayed as described later.

Next, when the “measurement result” frame is clicked on the display screen of FIG. 5, the CPU 31 displays the operation result display screen of FIG. At this time, the CPU 31
And request transmission of the temperature data recorded by the cool memory 3. The memory control unit 136 of the cool memory 3 responds to the polling from the personal computer 1 by the temperature alarm memory 143, the histogram memory 144,
Temperature data in the temperature history memory 146 and the memory 138
Is transmitted to the personal computer 1 via the signal line 17 by the interface 132.

The CPU 31 of the personal computer 1 is a cool memory 3
After temporarily writing the data transmitted from the memory 32 to the memory 32, the data is displayed on the operation result display screen of FIG. In this case, the CPU 31 displays the temperature data in the temperature history memory 146 (the data to which the time stamp is added as described above) numerically in the “temperature data” column, and displays the histogram data in the histogram memory 144 as “temperature distribution”. The data in the temperature alarm memory 143 is also displayed in the alarm column (displayed with the start date and time and the end date and time of high and low temperatures).

At this time, the CPU 31 corrects the temperature data using the measurement error data read from the cool memory 3 and displays it on the CRT display 6. That is, as described above, when the temperature data from the cool memory 3 is, for example, −40 ° C., the displayed temperature is −40.5 ° C., and when the temperature data is −20 ° C., the displayed temperature is −20 ° C. 0 ° C
Is + 0.4 ° C, + 20 ° C
, The displayed temperature is + 20.3 ° C., and if it is + 40 ° C., the displayed temperature is +40.
1 ° C.

As a result, the personal computer 1 can more accurately display the temperature history of refrigerated food (recording target) such as a lunch box or beverage in a container delivered to a convenience store, and record the temperature of the food. And management can be performed more accurately and accurately.
In particular, in the embodiment, since the measurement error data is written in the memory 138 of the cool memory 3, when a plurality of cool memories 3 are used,
This eliminates the necessity of holding the measurement error data, thereby simplifying the work required for error correction.

Next, a "graph" in the "temperature distribution" column of FIG.
When the frame is clicked with the mouse 9, the CPU 31 displays a temperature distribution graph display screen shown in FIG. In this screen, the horizontal axis is temperature (−40 ° C. in the example).
To + 70 ° C.), and the vertical axis indicates the number of times (0 to 200 in the example).
The recorded histogram is displayed in the bar graph of the times. Thereby, the temperature history of the conveyed food or the like into which the cool memory 3 is put can be grasped by the histogram.

Next, when the “vertical axis change” frame on the display screen of FIG. 9 is clicked, the CPU 31 displays the vertical axis change screen of FIG. 10 on the CRT display 6. On this screen, in addition to the screen of FIG. 9, “Change of vertical axis: maximum value position designation” is displayed. When the user clicks around 100 times on the screen of FIG. 10, for example, the CPU 31 displays the screen of FIG. 11 on the CRT display 6. In the screen of FIG. 11, the maximum value on the vertical axis is displayed as 100 times (the minimum value is 0 times). As a result, the range of 0 to 100 times in the bar graph displayed in FIG. 9 is enlarged and displayed. Clicking on the “Return to initial drawing” frame on the screen display of FIG.
The PU 31 returns the screen display to FIG.

As described above, when displaying the temperature data recorded corresponding to the time on the CRT display 6, an arbitrary range of the graph display can be designated and enlarged, so that the CRT display 6 is small like a mobile personal computer. Even in this case, it is possible to easily confirm and analyze the graphical display of the temperature data recorded for a long period of time, and it becomes extremely convenient especially during the transportation of the low-temperature food. In addition, since it becomes possible to specify a range to be enlarged by clicking the mouse 9 and to perform other input operations, operability is significantly improved.

On the display screen shown in FIG. 11, the same operation is performed to specify an arbitrary range, so that the CPU 3
1 further enlarges and displays the range. That is, such enlarged display can be executed recursively. However, "Return to initial screen"
When the frame is clicked with the mouse 9, the screen always returns to the screen of FIG. 9 at one time.

Next, in the display state of FIG. 8, when the "graph" frame in the "temperature data" column is clicked with the mouse 9,
The CPU 31 displays the temperature data graph display screen shown in FIG. In the graph on this screen, the horizontal axis is the time axis, and the vertical axis is the temperature, and the transition (history) of the recorded temperature is displayed by a line L1. This allows
The transition of the temperature of the conveyed food or the like into which the cool memory 3 is put can be grasped.

In the graph display screen, the CPU 31 sets the background color of the high-temperature warning area above the temperature warning upper limit to, for example, red and the background color of the low-temperature warning area below the temperature warning lower limit to, for example, blue. This makes it possible to easily identify a time zone in which the temperature exceeds the upper and lower limits of the temperature alarm in the course of the temperature transition.

In the graph display screen of FIG.
When the "comment addition mode" frame (not shown) in the menu bar of the RT display 6 is selected with the mouse 9, the CRT display 6 of the personal computer 1 enters the comment addition mode. In this comment addition mode, CR
When, for example, an arbitrary point (hereinafter, referred to as a designated point) P of the line L1 on the T display 6 (hereinafter referred to as a designated point) P (in FIG. A comment field CF as shown in FIG.

Furthermore, the designated point P can be moved to, for example, an arbitrary position on the line L1 by dragging with the mouse 9.

In the comment field CF, a comment (comment) can be input with a predetermined number of characters. In this case, first, the comment field CF is clicked with the mouse 9 to move the focus to the comment field CF, and characters are input while the cursor is displayed there.

For example, when a graph is displayed on the CRT display 6 and the transition of the temperature is observed, the temperature of the designated points P1 and P2 is rapidly reduced (or increased) at the designated points P1 and P2 of the line L1. If it is determined that it is a point that should be particularly noted, comment fields CF1 and CF2 are created as in the embodiment, and a required comment is written and displayed there. As a result, the displayed graph can be more easily analyzed, and advanced data analysis can be realized.

The comment field CF can be arbitrarily deleted by selecting it with the mouse 9 and pressing a delete key (not shown) on the keyboard 4. In addition, the comment addition mode ends with a predetermined end operation.

Next, on the graph display screen of FIG.

The time axis displayed in FIG. 15 indicates the elapsed time as shown in FIG. The “0” point of this elapsed time can be arbitrarily set by selecting a predetermined point on the time axis with the mouse 9 (the left end is the “0” point in the embodiment).

As described above, the time axis of the graph display can be selected and displayed in two types, the absolute time and the elapsed time. In addition to the temperature transition corresponding to the time, a arbitrarily selected specific time point is used as a reference. The transition of the temperature can be displayed in a form corresponding to the elapsed time, and the data can be analyzed from various directions to perform a more advanced analysis.

Next, on the graph display screen of FIG.
When a “graph line type setting” frame (not shown) in the menu bar of the CRT display 6 is selected with the mouse 9,
The CPU 31 displays the CRT display 6 of the personal computer 1 as shown in FIG.
A graph line type setting screen as shown in FIG. 6 is displayed. The numbers arranged on the left side of this graph line type setting screen are the plural cool memories 3

Further, the “measurement start date and time” on the display screen of FIG.
In the fields, start date and time of temperature measurement are set in year, month, day,
The time can be set in minutes. When the measurement start date and time are set, the CPU 31 displays the standby time from the current time to the start of measurement on the lower side.

Further, in the "measurement interval" column, the interval of temperature measurement can be set in minutes. When this measurement interval is set, the CPU 31 displays a measurement period until the data amount of the memory 146 of the cool memory 3 is saturated on the right of the maximum memory capacity. In the "memory overwrite" column, whether or not to execute memory overwrite as described above can be set by clicking. The total measurement count is also displayed on the right side of the “memory overwrite” column. "Memo input"
When the user clicks in the column, predetermined memo contents such as a measurement location can be written as described above.

In the "temperature alarm" column, the upper limit temperature at which the above-mentioned high temperature alarm is issued and the lower limit temperature at which the low temperature alarm is issued can be set. Note that the CPU 31 also refers to the above-described measurement error data when setting the upper limit temperature and the lower limit temperature. At this time, if there is no measurement error data in the cool memory 3 in the memory 32, the cool memory 3 is polled and requested.

Then, the input upper limit temperature and lower limit temperature are internally corrected (the display is not changed) and transmitted to the cool memory 3 as described later. That is, for example, if the input temperature is −40 ° C., it is −39.5 ° C., if it is −20 ° C., it is −20 ° C., if it is 0 ° C., −0.4 ° C.,
+ 19.7 ° C for + 20 ° C and + 40 ° C
In this case, it is transmitted to the cool memory 3 as + 39.9 ° C. As a result, an accurate high-temperature alarm / low-temperature alarm is issued.

When all the setting items have been set, the user clicks the “setting end” frame on the display screen of FIG.
When the “setting end” frame is clicked, the CPU 31
The various setting data set in FIG. 7 is transmitted to the signal line 17 via the bus I / O interface 34 together with the ID code of the cool memory 3.

The cool memory 3 has an interface 132
Receives various setting data to which its own ID code is attached by the memory control unit 136,
Write 37. Thereafter, the cool memory 3 operates according to the various setting data.

Here, when distributing low-temperature articles in such a convenience store chain, it is necessary to set the same setting data such as the measurement start date and time and the measurement interval in a plurality of cool memories 3. In such a case, the “batch setting” frame is clicked with the mouse 9 on the display screen of FIG. When this "batch setting" frame is clicked, the CPU 31 transmits various setting data set on the screen above it to all of the previously searched cool memories 3 (here, three).

In this case, the CPU 31
.. Are sequentially attached and various setting data are transmitted to the respective cool memories 3. As a result, the same setting can be collectively performed for a plurality of cool memories 3..., And the setting workability is significantly improved.

In the delivery of such low-temperature articles, the setting contents are often patterned depending on, for example, the delivery time and delivery distance in the morning, afternoon, and evening, and the storage temperatures of room temperature, freezing, and refrigeration. In such a case, after the various items are patterned and set on the start setting screen of FIG. 7 as described above, the “memory” frame is clicked with the mouse 9. When the “storage” frame is clicked, the CPU 31 writes the setting contents to the hard disk 7 in a file format. At this time, the file name is also stored.

When the "reference" frame on the display screen of FIG. 7 is clicked, the CPU 31 displays the setting content file name written on the hard disk 7 in a window on the CRT display 6 as described above. Is selected, various setting contents stored in advance are displayed on the display screen of FIG. "Batch setting" in this state
By clicking on the frame or the “setting completed” frame, the setting content stored in advance by the CPU 31 is transmitted to each cool memory 3 as described above. Thereby, the setting workability of the cool memory 3 is further improved.
In this case, the upper limit temperature and the lower limit temperature are corrected and transmitted.

Next, when the “file” frame is clicked with the mouse on the display screen of FIG.
The "file output" frame is displayed as shown in (1). When the "file output" frame is clicked, the CPU 31 displays the save screen with the file name shown in FIG. On this screen, enter the file location and file name, and click the “Save” frame.
Saves the temperature data and the alarm data read from the selected cool memory 3 in a file format on the hard disk 7.

Also in this case, the CPU 31 refers to the measurement error data, corrects the temperature data in the same manner as described above, and stores the corrected data in the hard disk 7.

Here, when the alarm confirmation software of the personal computer 1 is started, the CPU 31 displays an alarm confirmation dialog "Please set a cool memory." On the CRT display 6 in FIG. In this state, when one cool memory 3 is stored and connected to the storage section 11 of the button reader 2, the CPU 31 automatically polls the cool memory 3 and the temperature alarm memory 1 of the cool memory 3.
Request transmission of the data in 43.

The memory control unit 136 of the cool memory 3
In response to the polling from the personal computer 1, the data in the temperature alarm memory 143 is transmitted to the personal computer 1 through the signal line 17 by the interface 132. The CPU 31 of the personal computer 1 determines whether at least one high or low temperature alarm data exists in the data transmitted from the cool memory 3, that is, the temperature data exceeds the upper limit temperature even once in the cool memory 3, or If there is a history that the temperature has fallen below the lower limit temperature, "abnormal" is displayed on the alarm confirmation dialog of the CRT display 6 together with the ID code (ID number) and the memo of the cool memory 3 as shown in FIG.

When there is no temperature alarm data in the temperature alarm memory 143, the CPU 31 displays "normal" in the alarm confirmation dialog. Thereby, the user can easily and quickly confirm that the temperature alarm has occurred in the cool memory 3. Then, the detailed operation result may be confirmed on the operation result display screen.

During a pull-down period, for example, immediately after the start of operation of the low-temperature delivery vehicle, or during loading into the low-temperature delivery vehicle, the surroundings of the cool memory 3 are temporarily, but relatively high ( For example, room temperature). In such a case as well, the data of the temperature alarm is written in the temperature alarm memory 143 in the cool memory 3. However, in the alarm confirmation work as described above, issuing an alarm in such a situation is rather confusing. Become.

Therefore, by setting the time in minutes in the "alarm delay" column on the display screen of the start setting in FIG. 7, the alarm delay time from the start of the measurement and from the occurrence of the abnormality can be set. . That is, this "alarm delay"
For example, 10 minutes in the column (can be set in the range of 1 minute to 10 minutes)
Is set in the memory 32 or the hard disk 7 of the personal computer 1. When the personal computer 1 reads out the data from the cool memory 3, and when the temperature warning data is written in the temperature warning memory 143 of the cool memory 3, the data exceeds the upper limit temperature or lower limit, for example. If the temperature falls below the temperature and returns to the normal range (a temperature range lower than the upper limit temperature and higher than the lower limit temperature) within 10 minutes from the start of the state, the CPU 31 ignores the data of the alarm.

As a result, it is possible to prevent a temperature abnormality during the pull-down or loading operation as described above or a temporary temperature abnormality from being issued in the alarm checking operation.

In the embodiment, the present invention is applied to the temperature recording system for recording the temperature of the recording object. However, the present invention is not limited to this.
The present invention is also effective for output to a personal computer.
