At this time, in the non-simultaneous start-up circuit 13d, the entire storage 6 is prevented from becoming a load at one time, and an excessive starting current is generated in the storage 6 due to the insertion and connection of the start-up current reducing device 11, or unintended. When an in-vehicle generator 13a is used, an undesired load is applied to the engine, and an unnecessary load is prevented from being applied to the engine.

Here, as shown in FIG. 3, the internal temperature of each storage 6 is compared with a desired temperature set by the alarm temperature detector 9a, and a normal temperature lower than the temperature is maintained. As a result, the temperature detection means 9 activates the temperature abnormality alarm signal generation means 10 at the next stage, whereby the light signal from the light emitting element 10b by the light signal transmitter 10a is provided to the carrier 4. Incident on the light receiving element 14a of each of the temperature abnormality alarm signal receiving means 14. In such a state, there is no temperature abnormality warning output signal S from the optical signal receiver 14b to the temperature abnormality warning means 15, and therefore,
Since the temperature abnormality alarm means 15 does not operate, all the alarm monitoring lamps 15a are turned on, and the driver or the like in the cab 4a operates while confirming that there is no abnormality.

Next, when the internal temperature of the storage 6 rises above the set temperature, this is detected by the temperature detecting means 9 and the operation of the temperature abnormality alarm signal generating means 10 is stopped. As a result, the signal from the optical signal transmitter 10a disappears, the transmission of the optical signal from the light emitting element 10b stops, and as a result, the optical signal does not enter the light receiving element 14a of the temperature abnormality alarm signal receiving means 14. Based on this,
The temperature abnormality alarm signal S is input from the optical signal receiver 14b to the temperature abnormality alarm means 15, and the alarm monitoring lamp 15a corresponding to the storage 6 having an abnormality in the internal temperature is turned off.

By opening 5c, the alarm monitoring lamp 15a is turned on and the alarm sound of the alarm 15d is stopped. At this time, the driver or the like abnormally increases the internal temperature of the storage 6. Investigate the cause, promptly remove the cause, confirm the normal condition, and continue operation.

Since the abnormal temperature alarm signal generating means 10 and the abnormal temperature alarm signal receiving means 14 are connected by an optical signal as described above, the storage 6 is compared with the case where both are connected by wire. Is easy to transship
Not only that, in the present invention, is HaiSo to the light emitting element 10b and the light receiving element 14a is opposed with a height difference
Therefore, if the storage 6 moves involuntarily in FIG. 1 , the left-right direction and the front-back direction
Of course, which direction along the floor of the storage compartment 12
Optical signal from the light emitting element 10b also by shifting to the light receiving element 1
4a will not be incident on the light-emitting element 4a.
When the optical elements are at the same level and face sideways,
In contrast to the abnormal temperature rise, the driver and the like can use the temperature abnormality alarm means 15 to achieve high reliability.
Thus, it is possible to know the displacement of the storage 6 .
Also, when power supply was not provided to the storage,
This can also be confirmed by the loss of the optical signal.
You.

In this way, when the transport vehicle 4 arrives at another destination as a destination, the storage 6 in the storage loading room 12 is unloaded from the outlet 13f and unloaded. Installation location 16 of the above storage
The storage 6 is arranged at a predetermined position in the same manner as in the transport vehicle 4 and the plug of the power cord 6e is inserted into the installation outlet 16e of the installation power supply unit 16c. At this time, a considerable amount of time may be required to transport the storage 6 of the transport vehicle 4 to the installation location 16 as described above. In the case of the storage 6 which is a refrigerated container, the internal temperature of the storage 6 is undesired. In order to prevent the temperature from rising too high, it is preferable to store a cold storage body obtained by freezing a saline solution or the like in the container in the storage 6. Even if power is not supplied at the time of transfer, undesired rise in internal temperature is reliably prevented.

The storages 6 arranged at other points as described above are provided with a power supply section 16c for installation provided in the same manner as the equipment of the transport vehicle 4 and the temperature abnormality alarm signal generation means 10 for these storages 6 Since there is provided a temperature abnormality alarm signal receiving means 18 for installation which operates upon receiving a temperature abnormality alarm signal, and a temperature abnormality alarm means 17 for installing the connection thereto,
The clerk at the other point manages abnormal temperature rise or abnormal transition of the storage 6 by using the monitoring room 16d, the alarm display 17a at the installation location 16, or the like. Of course, when the other point is the collection center 2, the storage 6 is transported from here to the recipient 3 by the transport vehicle 4 in the same manner as described above. In the present embodiment, low-temperature transportation of frozen blood and the like has been exemplified. However, as described above, the present invention can be applied to transportation of medical products and the like that need to be stored at about 25 ° C. by selecting an appropriate storage. Needless to say.
