Has been.

  The fuel tank 110 contains fuel necessary for operating the engine 120. For example, gasoline is stored in the fuel tank 110 when the engine 120 is a gasoline engine, and light oil is stored in the fuel tank 110 when the engine 120 is a diesel engine.

  The power generated from the engine 120 is supplied to the generator 130, and the generator 130 generates power using this power.

  The cold air generator 140 is operated by electricity supplied from the generator 130 and generates the cold air necessary for cooling the refrigerated goods.

  The battery 150 charges electricity supplied from the generator 130. The battery 150 is composed of, for example, a lithium ion secondary battery (next-generation battery).

  The generator 130 operates the cold air generator 140 and charges the battery 150 with surplus power.

  The switch 145 is connected to the generator 130, the battery 150, and the cool air generator 140, and supplies electricity from either the generator 130 or the battery 150 to the cool air generator 140.

  The pump 115, the engine 120, the generator 130, and the cold air generator 140 are controlled to be turned on / off by signals transmitted from the control device 160. Specifically, when an ON signal is transmitted from the control device 160, the pump 115, the engine 120, the generator 130, and the cold air generator 140 start operation, and when an OFF signal is transmitted from the control device 160, the pump 115, the engine 120, the generator 130, and the cool air generator 140 stop operating.

  The switch 145 connects either the generator 130 or the battery 150 and the cold air generator 140 in accordance with a signal transmitted from the control device 160.

  The cold air generation system 100 is disposed, for example, in one iron box 101.

  For example, a freezing box 170 is disposed adjacent to the iron box 101. A freezing article 171 is stored inside the freezing box 170.

  The cold air generated from the cold air generator 140 is introduced into the freezing box 170 through the cold air introduction path 180. In addition, the cold air in the freezing box 170 is returned to the cold air generator 140 via the cold air circulation path 181.

  The cold air generation system 100 according to this embodiment having the above-described configuration operates as follows.

  FIG. 2 is a flowchart showing the operation of the control device 160 of the cold air generation system 100 according to the present embodiment.

  As described above, the cold air generation system 100 according to the present embodiment is disposed, for example, inside the iron box 101, and the iron box 101 is mounted on a truck or other vehicle together with the freezing box 170.

  The control device 160 continuously determines whether or not the operation of the generator 130 is permitted (step S100 in FIG. 2).

  When the operation of the generator 130 is permitted (step S110 in FIG. 2), the control device 160 operates the pump 115, the engine 120, the generator 130, and the cold air generator 140 while the truck is running. At the same time, the generator 130 and the cold air generator 140 are connected via the switch 145.

  The generator 130 that is supplied with power from the engine 120 generates power. The cold air generator 140 operates by receiving electricity from the generator 130 via the switch 145 and generates cold air. The generated cold air is introduced into the freezing box 170 through the cold air introduction path 180, and the freezing article 171 housed in the freezing box 170 is cooled. The cold air circulates through the cold air generator 140 and the freezing box 170 via the cold air introduction path 180 and the cold air circulation path 181, and the inside of the freezing box 170 is always filled with the cold air maintained at a constant temperature.

  Of the electricity generated by the generator 130, electricity other than that required for the operation of the cold air generator 140, that is, surplus electricity is charged in the battery 150.

  When it becomes a state where the generator 130 must be stopped (for example, when a truck travels in a region where the operation of the generator 130 is prohibited (such as inside a tunnel)) (step S120 in FIG. 2), the control device 160 Stops the operation of the pump 115, the engine 120 and the generator 130, and connects the battery 150 and the cold air generator 140 via the switch 145.

  By this switching, the cool air generator 140 operates by receiving electricity from the battery 150 and generates cool air.

As a result, the cold air generator 140 operates by receiving the supply of electricity from the generator 130.

  When the operation of the generator 130 is not permitted (for example, when a truck equipped with the cold air generation system 100 travels inside the tunnel) (step S120 in FIG. 2), the control device 160 causes the generator 130 to operate. While stopping, the battery 150 and the cold air generator 140 are connected via the switch 145. As a result, the cool air generator 140 receives power from the battery 150 and operates.

  As described above, according to the cold air generation system 100 according to the present embodiment, even when the operation of the generator 130 is not permitted, the battery 150 supplies electricity to the cold air generator 140 and the operation of the cold air generator 140 is performed. Can be continued. For this reason, it is possible to maintain the refrigeration required article 171 accommodated in the freezing box 170 at a low temperature regardless of whether the generator 130 is operated.

  In addition, the cold air generation system 100 according to the present embodiment is not necessarily manufactured integrally with the refrigeration container (the refrigeration box 170 in the present embodiment) that houses the refrigeration items 171 required. It is possible to attach from.

Is stored. The central processing unit 161 reads a program from the first memory 162 and executes the program. That is, the central processing unit 161 operates according to a program stored in the first memory 162.

  As described above, the cold air generation system 100 according to the present embodiment can also be operated by the program stored in the control device 160.

(Second embodiment)
FIG. 4 is a schematic view of a cold air generation system 200 according to the second embodiment of the present invention.

  In the cold air generation system 200 according to the present embodiment, a thermometer 175 that measures the temperature inside the freezing box 170 and transmits a temperature signal indicating the temperature to the control device 160 is installed inside the freezing box 170. . Except that a thermometer 175 is installed inside the freezing box 170, the cold air generation system 200 according to the present embodiment has the same structure as the cold air generation system 100 according to the first embodiment.

  The control device 160 controls the on / off of the cold air generator 140 according to the temperature inside the freezing box 170 indicated by the temperature signal. Specifically, when the temperature inside the freezer box 170 indicated by the temperature signal is higher than the set temperature, the cool air generator 140 is operated, and the temperature inside the freezer box 170 indicated by the temperature signal is lower than the set temperature. The operation of the cold air generator 140 is stopped.

  In this manner, the control device 160 controls the on / off of the cold air generator 140 according to the temperature inside the freezing box 170 indicated by the temperature signal, thereby maintaining the temperature inside the freezing box 170 at the set temperature. Is possible.

(Third embodiment)
FIG. 5 is a schematic view of a cold air generation system 300 according to the third embodiment of the present invention.

  The cold air generation system 300 according to the present embodiment includes a GPS system 310 that detects the position of the cold air generation system 300. The cold air generation system 300 according to this embodiment has the same structure as the cold air generation system 100 according to the first embodiment except that a GPS system 310 is additionally provided.

  The GPS system 310 transmits a position signal indicating the position of the cold air generation system 300 to the control device 160.

  The control device 160 controls the operation of the switch 145 according to the position of the cold air generation system 300 indicated by the position signal.

  Specifically, when the position of the cold air generation system 300 is within an area where the operation of the generator 130 is allowed, the control device 160 operates the generator 130 and also uses the switch 145 to generate the generator 130. And the cold air generator 140 are connected. As a result, the cold air generator 140 operates by receiving the supply of electricity from the generator 130.

  When the cold air generation system 300 is about to enter an area where the operation of the generator 130 is not allowed (for example, when a truck equipped with the cold air generation system 300 is about to enter the tunnel), the control device 160 At a point before entering the area (for example, a point two kilometers before the tunnel), the operation of the generator 130 is stopped and the battery 150 and the cold air generator 140 are connected via the switch 145. As a result, the cool air generator 140 receives power from the battery 150 instead of the generator 130 and operates.

  Furthermore, when the control device 160 determines that the cold air generation system 300 has come out of the above-described region based on the position signal from the GPS system 310, the control device 160 again connects the generator 130 via the switch 145. The cold air generator 140 is connected and the generator 130 is operated. As a result, the cool air generator 140 is supplied with electricity from the generator 130 instead of the battery 150 and operates.

  As described above, in the cold air generation system 300 according to the present embodiment, whether or not the current position of the cold air generation system 300 is within the region where the operation of the generator 130 is allowed, based on the position signal from the GPS system 310. Alternatively, the control device 160 determines whether it is out of the region, and according to the determination result, the control device 160 connects either the generator 130 or the battery 150 to the cold air generator 140, and sets the cold air generator 140 to Operate.

  As described above, according to the cold air generation system 300 according to the present embodiment, the control device 160 selects an appropriate one of the generator 130 and the battery 150 according to the current position of the cold air generation system 300, and The generator 140 is activated. For this reason, the usage time of the battery 150 can be made the shortest time, and hence the chargeable amount of electricity of the battery 150 can be reduced, so that the size of the battery 150 can also be reduced.

  The time required to pass through the Seikan Tunnel, which is said to be the longest in Japan, is about 40 minutes. For this reason, it is preferable that the battery 150 is set to have an electric capacity for operating the cold air generator 140 for about 80 minutes, which is the time required for the round trip of the Seikan Tunnel. Most preferably, the battery 150 is set to have a capacity to operate the cold generator 140 for 3 hours.

The control center 160 that has received the transmitted control signal controls the operation of the switch 145 as in the third embodiment.

  That is, when the position of one cool air generation system 400 is within an area where the operation of the generator 130 is allowed, the management center 450 transmits a control signal to the control device 160 and receives the control signal. 160 activates the generator 130 and connects the generator 130 and the cold air generator 140 via the switch 145. As a result, the cold air generator 140 operates by receiving the supply of electricity from the generator 130.

  When the cold air generation system 400 is about to enter an area where the operation of the generator 130 is not allowed (for example, when a truck equipped with the cold air generation system 400 is about to enter the tunnel), the management center 450 The control signal is transmitted to the control device 160 at a point before the cold air generation system 400 enters the region (for example, a point two kilometers before the tunnel). The control device 160 that has received the control signal stops the operation of the generator 130 and connects the battery 150 and the cold air generator 140 via the switch 145. As a result, the cool air generator 140 receives power from the battery 150 instead of the generator 130 and operates.

As a result, the cool air generator 140 is supplied with electricity from the generator 130 instead of the battery 150 and operates.

  As described above, according to the cold air generation system 400 according to the present embodiment, the management center 450 can grasp the positions of the plurality of cold air generation systems 400, and according to the respective positions of the cold air generation systems 400, The operation of the cold air generation system 400 can be controlled at one place.

(Fifth embodiment)
