Further, when the connected cooling / heating pipe L2 does not correspond to the desired temperature, the display unit 17 displays an alarm by turning on the LED in red.

(Information collection device)
As illustrated in FIG. 2, the information collection device 30 includes a communication unit 31, a control unit 32, and a storage unit 33. The communication unit 31 can be connected to the plurality of transport boxes 1 via the communication line L1. The communication unit 31 is also connected to the cooling / heating machine 40. In addition, you may make it the communication part 31 connect the connection with the refrigerator 40 via the communication line L1. The communication unit 31 is connected to the higher-level information management device 130 via the network N.

  The control unit 32 acquires the transport box identification information 14 and the transport box history information 15 of the transport box 1 connected to the communication line L1 via the communication unit 31. In addition, the control unit 32 acquires connection information 35 between the chiller 40 and the transport box 1.

The control unit 32 transmits the acquired transport box identification information 14, transport box history information 15, position information 34 of the information collection device 30, connection information 35, and operation information 36 to the upper information management device 130 side.

(Cooler)
As shown in FIG. 2, the cooling / heating machine 40 includes a cooling / heating controller 41 and a cooling / heating circuit 42. The cooling / heating circuit 42 is a known refrigeration cycle apparatus including, for example, a compressor, a condenser, an expansion valve, and the like (not shown). For example, the cold medium is rapidly cooled to a desired temperature range, and the rapidly cooled cold medium is supplied to the cooler 21 via the cold pipe L2. A circulation pump (not shown) for circulating the cooling medium is provided. The cold medium is a so-called brine medium such as water or an antifreeze. The cooling / heating controller 41 controls the cooling / heating circuit 42 and controls communication with the information collecting device 30.

(Transport box connection form)
By the way, since the refrigerator / heater 40 is not arrange | positioned in the shop 120, as shown in FIG. 4, each conveyance box 1 is connected to the information collection device 30 via the communication line L1. In this case, the transport box identification information 14 and the transport box history information 15 of each transport box 1 are only transmitted to the upper information management apparatus 130 side as a pair. The history information collection at the store 120 is a state in which the product 101 is stored in the transport box 1 until immediately before, and the latest transport box history information 15 can be quickly collected.

  On the other hand, in the distribution center 110, an information collecting device 30 and a plurality of chillers 40 are arranged. As shown in FIG. 4, when a plurality of cooling machines 40 are arranged, it is preferable that the cooling controller 41 has a function as a lower-level information collection device. In this case, each cooling controller 41 collects the transport box identification information 14 and the transport box history information 15 of the transport box 1 to be connected, and transmits the collected information to the information collection device 30. At this time, the cooling / heating controller 41 transmits the position information 34, the connection information 35, and the operation information 36 of the cooling / heating machine 40 to the information collecting device 30. When the cooling capacity of each chiller 40 is set to be different, the transport box 1 is managed in units of each chiller 40, and therefore it is possible to quickly determine whether the transport box 1 is erroneously connected. In addition, even if the cooling capacity of each chiller 40 is the same, the operation state may vary depending on the arrangement position of the chiller 40, but because the operation information 36 for each chiller 40 unit is acquired, The deviation in the operating state of the chiller 40 can be quickly determined.

(Communication processing of information collection device)
FIG. 5 is a flowchart illustrating a communication processing procedure of the information collection device 30. As shown in FIG. 5, the information collection device 30 determines whether or not the transport box 1 is connected via the communication line L1 (step S101). When the transport box 1 is not connected (step S101, No), this process is repeated. When the transport box 1 is connected (step S101, Yes), the connected transport box 1 is selected. A unique communication address is assigned (step S102).

  Thereafter, communication between the information collection device 30 and each transport box 1 is established using this unique communication address (step S103). Furthermore, using this unique communication address, the information collection device 30 acquires the transport box identification information 14 and the transport box history information 15 held in each transport box 1 (step S104). Thereafter, the acquired transport box identification information 14 and transport box history information 15 are paired and transmitted to the higher-level information management device 130 (step S105). At this time, the information collection device 30 also transmits the location information 34 of the information collection device 30 and the like to the higher-level information management device 130. The above-described processing is repeated every predetermined time.

  The above-described allocation of the unique communication address can be realized by the unique configuration of each communication connection unit C11 connected to one communication line L1. For example, FIG. 6 shows a configuration for generating a 3-bit communication address. By forming the turn-back unit 60 on the communication connection unit C11 side, a communication address unique to each communication connection unit C11 is assigned to the communication processing unit 11. Then, communication between the information collecting device 30 and each transport box 1 can be established simply and easily using this unique communication address. Specifically, when the information collection device 30 accesses the transport box 1 connected to each communication connection unit C1 in a time division manner and the transport box 1 is connected, the unique information set by the communication connection unit C11 is set. Communication is established by notifying the information collection device 30 of the communication address of the first communication address.

  In addition, as shown in FIG. 4, even if it does not collect the information of each transport box 1 in the cooling / heating machine 40 unit, the cooling / heating machine 40 connected to the communication connection part C11 connected to the communication line L1 can be discriminated. By setting a unique communication address, it is possible to collect information on each transport box 1 in units of the refrigerator 40.

(Colder valve opening / closing control by the Information Management Department)
FIG. 7 is a flowchart showing a valve control processing procedure for the refrigerator valve 26 by the information management unit 10. As shown in FIG. 7, first, the control unit 12 determines whether communication with the information collection device 30 is being established based on the processing state of the communication processing unit 11 (step S201). . If the communication is not established (No at Step S201), the determination process at Step S201 is continued. If the communication is established (Step S201, Yes), whether or not the cooling pipe L2 is further connected. Is determined (step S202). This determination is made based on the detection result of a connection detection sensor (not shown) provided in the cooling medium connection part C2. The cooling medium connection portion C2 includes a cooling medium connection portion C21 on the cooling heat pipe L2 side and a cooling medium connection portion C22 on the transport box 1 side. When the cooling / heating pipe L2 is not connected (step S202, No), the determination process of step S202 is further repeated. When the cooling / heating pipe L2 is connected (step S202, Yes), the cooling / heating pipe L2 is further increased. It is determined whether or not the connection is suitable for the transport box 1 (step S203). That is, it is determined whether the cooling capacity of the cooling machine 40 and the desired temperature required by the transport box 1 are compatible. Note that specific different desired temperatures are, for example, 0 ° C. and −10 ° C.

  When the connection of the cooling / heating pipe L2 is compatible with the transport box 1 (step S203, Yes), the control unit 12 performs control to open the cooling / heating valve 26 (step S204). Thereafter, based on the detection result of the temperature sensor 25, it is determined whether or not the temperature of the cold insulation heat space 23 is maintained at a desired temperature for a predetermined time (step S205). If the temperature of the cold insulation heat space 23 does not maintain the desired temperature for a predetermined time (step S205, No), the determination process of step S205 is repeated, and the temperature of the cold insulation heat space 23 maintains the desired temperature for the predetermined time. If yes (step S205, Yes), a usable display indicating that the reuse is possible is displayed on the display unit 17 (step S206). Thereafter, it is determined whether or not the communication with the information collecting device 30 is disconnected or the cooling / heating pipe L2 is disconnected (step S207). When the communication with the information collecting device 30 is disconnected or when the cooling / heating pipe L2 is disconnected (step S207, Yes), the control unit 12 performs control for closing the cooling / heating valve 26 (step S208). The process ends.

  On the other hand, when the connection of the cooling / heating pipe L2 is not suitable for the transport box 1 (No at Step S203), the control unit 12 performs control to close the cooling / heating valve 26 (Step S209). Then, the control part 12 displays the alarm display which shows that the connection of the refrigerator 40 and the transport box 1 is incompatibility on the display part 17 (step S210), and complete | finishes this process. The above-described processing is repeated every predetermined time.

  In addition, although the control part 12 performed the valve control mentioned above, it is not restricted to this, You may make it the cooling-heat controller 41 obtain and control the information from each control part 12. FIG.
