[0029] In the origin, the operator inputs a measurement start command to the temperature recorder 10 provided in a low-temperature container C ₁ in the measurement start mode when starting. The operator turns on the power by holding the temperature checker 1 and pressing the switch 8 for a predetermined time. Next, the user sets the measurement start mode (SET) by pressing the changeover switch 8 while watching the liquid crystal display 7. Next, the joining portion 2 of the temperature checker 1 is joined to the cover 10B of the temperature recording device 10 for a certain time (for example, 1 second). In this operation, the reading lamp 3 of the temperature checker 1 is turned on. The temperature checker 1 transfers a measurement start command and a checker number corresponding to the place of production to the control unit 10F of the temperature recording device 10. Control unit 10F
Starts the temperature measurement based on the measurement start command, and stores the checker number and the temperature history at the measurement start time in the memory 10E. When the storing operation in the memory 10E is completed, the control unit 10F transfers the identification number unique to the temperature sensor 10C and the temperature history at the measurement start time to the temperature checker 1. The temperature checker 1 stores the transferred identification number of the temperature sensor 10C and the temperature history at the measurement start time in the memory 20A. After the measurement start operation of the temperature recording device 10 by the temperature checker 1 is performed in this way, the transportation is started.

FIG. 9 shows the temperature history stored in the temperature recording device 10. When the temperature measured by the temperature sensor 10C deviates from the appropriate temperature range between the low temperature threshold and the high temperature threshold as shown in FIG. It becomes temperature alarm state.

At the pickup site, when the marine product arrives, the temperature confirmation based on the temperature history stored in the memory 10E of the temperature recording device 10 in the temperature confirmation mode. I do.
The operator grasps the temperature checker 1 and holds the changeover switch 8
The power is turned on by holding down for a predetermined time.
Next, the user presses the changeover switch 8 while watching the liquid crystal display 7 to set the temperature check mode. Next, the joining portion 2 of the temperature checker 1 is joined to the cover 10B of the temperature recording device 10 for a predetermined time (for example, one second) (S1). In this operation, the reading lamp 3 of the temperature checker 1 is turned on. The temperature checker 1 transfers the temperature check command and the checker number corresponding to the collection base to the control unit 10F of the temperature recording device 10. Control unit 10F performs a temperature checking operation based on the temperature checking command. Temperature checker 1
The control unit 20 reads the temperature alarm history data from the memory 10E of the temperature recording device 10 (S2), and calculates a time during which the temperature has deviated from the high temperature threshold or the low temperature threshold and has been in the alarm state. The control unit 20 turns on the green normal lamp 6 when the integrated value of the alarm time does not exceed a set value, for example, 60 minutes (S3). The set value used at the time of this calculation is determined by the control unit 2
The memory set in the 0 memory 20A is used. Next, of the temperature history data stored in the memory 10E of the temperature recording device 10, the temperature history data at the latest time is read from the recording area 10I, converted into a temperature display signal by the display data creation unit 7A, and 7 is output. The liquid crystal display 7 performs temperature display according to the temperature display signal (S4). Further, when the integrated value of the alarm time exceeds the set value, the control unit 20 turns on the red abnormal lamp 5 and, out of the temperature alarm history data stored in the memory 10E of the temperature recording device 10, The temperature alarm history data of the highest temperature equal to or higher than the high temperature threshold is read from the recording area 10K, converted into a temperature display signal by the display data creation unit 7A, and output to the liquid crystal display 7. The liquid crystal display 7 performs temperature display according to the temperature display signal (S5).

As described above, the reason why the abnormal lamp 5 is turned on under the condition that the integrated value of the alarm time exceeds the set value is that the door of the low-temperature storage is opened for loading / unloading of the luggage and the temperature is lowered. This is to prevent a temperature that is not originally abnormal from being regarded as abnormal when the temperature is measured when the temperature temporarily rises.

When the temperature checking operation is completed, the control unit 10F of the temperature recording device 10 stores the identification number unique to the temperature sensor 10C and the temperature history at the temperature checking time into the temperature checker 1.
Transfer to The temperature checker 1 stores the transferred identification number of the temperature sensor 10C and the temperature history at the temperature confirmation time in the memory 20A.

Before the marine product departs from the collection base, the temperature is confirmed based on the temperature history stored in the memory 10E of the temperature recording device 10 in the temperature confirmation mode. In the temperature check operation at the time of departure, the temperature is checked according to the same processing flow as in the above-described temperature check mode.

Further, since the same applies to the relay point A and the relay point B, a duplicate description of the processing flow will be omitted.

In the market, an operator inputs a storage command to the temperature recording device 10 in the storage mode upon arrival. The operator turns on the power by holding the temperature checker 1 and pressing the switch 8 for a predetermined time. Next, the user presses the changeover switch 8 while watching the liquid crystal display 7 to set the storage mode (SAV). Next, temperature checker 1
Is bonded to the lid 10B of the temperature recording device 10 for a certain period of time. In this operation, the reading lamp 3 of the temperature checker 1 is turned on. The temperature checker 1 transfers a save command and a checker number corresponding to the place of production to the control unit 10F of the temperature recording device 10. The control unit 10F stops the temperature measurement based on the save command, and stores the checker number and the temperature history at the measurement stop time in the memory 10E. When the storing operation to the memory 10E is completed, the control unit 10F transfers the identification number unique to the temperature sensor 10C and all the temperature histories stored in the memory 10E to the temperature checker 1, and stops the temperature measurement based on the save command. I do. The temperature checker 1 stores the transferred identification number of the temperature sensor 10C and all the temperature histories in the memory 20A.

When the operator wants to stop the temperature measurement after the measurement of the temperature recording device 10 is started, the operator must use the temperature checker 1.
The power is turned ON by holding the switch 8 for a predetermined time while holding the switch. Next, by pressing the changeover switch 8 while watching the liquid crystal display 7, the measurement stop mode (OF
Set to F). Next, the junction 2 of the temperature checker 1
Is bonded to the cover member 10B of the temperature recording device 10 for a certain period of time. In this operation, the reading lamp 3 of the temperature checker 1 is turned on. The temperature checker 1 sends a measurement stop command and a checker number to the control unit 10 of the temperature recording device 10.
