DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature recording device for recording the history of the internal temperature of a container equipped with a refrigeration unit, for example, for maritime transport, and displaying the history as necessary. The present invention relates to a measure for improving the visibility of the history display of the internal temperature.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Application Laid-Open No. 4-96033.
In a container for marine transportation provided with a refrigerating device as disclosed in Japanese Patent Application Laid-Open Publication No. H10-209, the history of the temperature inside the refrigerator during transportation (change state of the temperature in the refrigerator from the start of transportation to the end of transportation) is recorded. A temperature recording device is provided. Then, after the transportation is completed, by checking the recorded data, it is possible to easily recognize whether or not the transportation state of the cargo (such as foodstuffs) is appropriate.

[0003] Further, as a general type of this type of temperature recording device, a temperature signal from a temperature sensor for detecting a temperature in a refrigerator is amplified and then input to a servomotor of a recording pen via a servo amplifier. With this, the recording pen is driven to draw a change in the internal temperature on the recording paper, or a memory device is provided, and the internal temperature at regular intervals is input thereto, and the input accumulation is performed. There is an example in which data is sequentially displayed as numerical values as needed.

[0004]

By the way, in this type of temperature recording apparatus, in order to eliminate the necessity of replacing the recording paper every time the transportation is completed and performing the initial setting of the memory device, the temperature recording apparatus is not required. It is conceivable to increase the capacity of the stored data. That is, for example, by extending the data storage capacity from two months to two years, the stored data in a plurality of transportations is collectively stored in the temperature recording device.

[0005] However, when the capacity of the temperature recording device is increased in this manner, the accumulated data of the previous transportation and the current transportation become continuous data, and the start point of the accumulated data of the transportation to be confirmed may be recognized. This makes it extremely difficult to recognize the transportation status of the cargo. More specifically, for example, in a situation where accumulated data for 10 times of transportation are continuously stored in the temperature recording device, when it is desired to confirm a change in the temperature inside the warehouse during cargo transportation performed six months ago. However, it is extremely difficult to recognize in which part of the total stored data the data indicating the temperature change from the start of transportation to the end of transportation in the freight transportation six months earlier is extremely difficult. There is a risk of misreading.

SUMMARY OF THE INVENTION The present invention has been made in view of this point, and it is possible to increase the capacity of a temperature recording device so as to collectively store accumulated data in a plurality of transportations in the temperature recording device.

Then, the data holding means (61) receiving these signals individually holds the temperature accumulation data between the accumulation start time signal output by the start time output means (62) and the next accumulation start time signal. In other words, since independent data is retained for each cargo transportation, when calling the data, the data is displayed for each data, that is, for each cargo transportation, and the data is displayed at the time of the desired cargo transportation. The temperature in the refrigerator can be easily checked.

According to a second aspect of the present invention, in the container interior temperature recording apparatus of the first aspect, the start point output means (62) is operated at the start of container transportation (7K-5).

The individual display means (64) displays the temperature accumulation data in the form of a graph. As shown in FIG. 7, the horizontal axis represents the operation time, and the vertical axis represents the internal temperature. Further, the individual display means (64) can individually display the operating state data of the refrigerator (20) held in the memory section (61) simultaneously with the temperature accumulation data.

Next, the cargo transport operation by the refrigeration container (10) will be described. First, a load is loaded on the container body (11), transportation is started, and the operation of the refrigeration apparatus (20) is started. At the same time, when the operator turns on the trip start key (7K-5), the start time output means
(62) outputs a start time signal, which is written into the memory unit (61), which stores the date at that time and accumulates the internal temperature data detected by the temperature sensor (44). To start.

At the start of operation of the refrigeration system (20), the compressor (41) operates at full load to perform rapid cooling of the refrigerator (pull-down operation). As a result, the internal temperature rapidly decreases to a control temperature range (hereinafter, referred to as an in-range).

When the inside temperature of the refrigerator once falls within the in-range by the pull-down operation, a normal cooling operation is executed, and the refrigerant circulation state of the refrigerant circuit (40) is controlled so that the inside temperature of the refrigerator maintains the in-range. I do. Note that the in-range is set within a predetermined temperature range with respect to the set temperature. For example, the in-range is set to a temperature range of ± 1 ° C. with respect to the set temperature. When the temperature is -20 ° C in the (refrigeration mode), the mode is the frozen mode (freezing mode).

On the other hand, in such an operating state, when the evaporator (43) is frosted (frosted), the defrosting operation is executed. The defrost operation is performed, for example, every four hours during the pull-down operation, and is performed every 12 hours or 24 hours during the cooling operation in which the temperature in the refrigerator is maintained within the in-range. Further, the defrost operation is performed even when the temperature in the refrigerator becomes higher than the in-range and the state in which the temperature is higher than the in-range continues for 30 minutes.

During such an operation, the temperature sensor (44) constantly detects the internal temperature, and the detected internal temperature data is stored in the memory ( 61).

Then, when the transportation is completed and the operation of the refrigeration system (20) is stopped and the package is carried out of the container (10),
The operation of accumulating the in-chamber temperature data ends. In this manner, the temperature change in the refrigerator from the start of transportation to the end of transportation in one transportation is stored in the memory unit (61) as accumulated temperature data.

Then, at the time of the next transportation, the operator turns on the trip start key (7K-5) at the same time as the transportation is started, and the operation start time is written in the memory unit (61). Then, the storage operation of the internal temperature data is started, and the change in the internal temperature until the end of the transportation is stored as data.

In this embodiment, as described above, the start time input means (62) automatically outputs the start time signal to the memory section (6).
It can output to 1). This operation will be described with reference to the flowchart of FIG. That is, the refrigeration system (20)
When the power supply unit switch is turned ON and the storage operation (logging) of the internal temperature data is started in step ST1, the current time is three days from the time when the storage of the internal temperature data was completed in the previous transportation. It is determined whether or not the time has elapsed.If the determination is NO, the power switch is temporarily turned off, and transportation is continued before and after the switching operation of the power switch. It is determined that the process has been performed, and the process ends without outputting the start time signal. On the other hand, in the case of YES after three days have elapsed, it is determined that the current ON operation of the power switch is for starting transport, and the operation start time is automatically written to the memory unit (61). . According to this operation, the operator does not need to turn on the trip start key (7K-5) every time the transportation is started. Note that the present apparatus is provided with a timer driven by a dry battery, and the detection of the period in which the power supply unit switch of the refrigeration apparatus (20) is in the OFF state is performed by measuring the time by the timer. ing.
Therefore, the above-mentioned period can be accurately detected regardless of the OFF operation of the power supply unit switch.

Then, as described above, the memory section (61)
Since the temperature storage data between the start time signal output by the start time output means (62) and the next start time signal are individually held, the temperature storage data of the previous cargo transportation and The temperature accumulation data of the present freight transportation is held as individual and independent data.

The above operation is repeated, and the memory unit
In (61), the respective temperature accumulation data corresponding to a plurality of times of freight transportation are individually held. In other words, for the entire temperature accumulation data, it is recognized that another cargo transportation is being performed before and after the part where the operation start time is written, and the temperature accumulation data corresponding to each cargo transportation is individually Is held.

Next, the operation for confirming the temperature accumulation data of the desired cargo transportation among the plurality of temperature accumulation data will be described. First, a personal computer (PC) is connected to a personal computer connection jack (not shown) provided in the controller (50), and temperature accumulation data confirmation software is started. Then, as shown in the display shown in FIG. 6, when data download (displayed in a hatched portion) is selected in a main menu and trip data (displayed in a hatched portion) is selected in a submenu, the data is held in the memory section (61). A list of storage start dates for each of the plurality of temperature storage data is displayed (portion A in FIG. 6). That is, the dates when the start time signal is output from the start time output means (62) to the memory unit (61) during each of the cargo transportations are displayed as a list. As a result, the start date of each cargo transportation in which the temperature accumulation data is stored in the memory unit (61) can be easily recognized.

From this state, when confirming the desired temperature accumulation data, the cursor is moved and selected and executed on the transportation start date of the cargo transportation to be confirmed, as shown in FIG. The change state of the temperature in the warehouse from the start of transportation of the freight transportation to the end of transportation is graphed and displayed on a display. FIG. 7 shows a case where the cargo is transported in the chilled mode in which the set temperature in the warehouse is 0 ° C.

The refrigeration system (2
When the details of the operation state of (0) are to be confirmed, the display mode is changed, and as shown in FIG. 8, an abnormality code indicating whether or not an abnormality has occurred in the operation state of the refrigeration system during the transportation of the cargo is displayed at the bottom of the graph. Will be displayed. For example, in FIG. 8, the state in which the low pressure side of the refrigerant circuit (20) has dropped below a predetermined value (code
E107), a state in which a sensor abnormality has occurred (code E111), and a state in which the high-pressure protection switch on the compressor discharge side has been activated (code E103) are displayed.

Further, a refrigeration system (20) for this cargo transportation
In order to confirm the details of the operation mode and the operation status of the various keys, the display mode is further changed, as shown in FIG. The operation status of various keys is displayed at the bottom of the graph. For example, in FIG. 9, the time T1 indicates the defrost operation state, the time T2 indicates the thermo-off state, and the other time indicates the thermo-on state, and the unit power supply is temporarily turned off (U.OFF). , The state in which the set temperature has been changed (SPC) is displayed. Also, in FIGS. 7 to 9, the change in the internal temperature for a maximum of 30 days is displayed on one screen, but the change in the display mode is displayed on a single screen for the change in the internal temperature for 60 days or 90 days. You can also.

As described above, in the container device of the present embodiment, the temperature accumulation data is divided by the start time signal output by the start time output means (62), and each of the divided data is individually stored in the memory unit ( 61), and each can be displayed individually.This eliminates the possibility of misreading the stored data due to the continuation of each data as in the past, and the temperature recording By increasing the capacity of the device, it is possible to collectively store the accumulated data in the plurality of transportations in the temperature recording device, while displaying only the desired accumulated data as necessary. The visibility of the temperature history display is improved, and the temperature in the refrigerator can be easily analyzed.

In this embodiment, a personal computer (PC) is connected to the controller (50) to call out data. However, the present invention is not limited to this, and the display input unit (70) and the like may be used for display. May be provided to perform data display. In this case, the data display unit is provided in the container device itself, so the personal computer
The necessity of (PC) and its connection work can be eliminated.

Although the temperature accumulation data is displayed as a graph, the present invention is not limited to this.
Numerical values may be individually displayed for each temperature accumulation data.
