The unit-side power supply device 230 of the first embodiment is a storage battery. Since there are forklifts, workers, and the like in and out of the freezer warehouse 100, the wiring of lines is restricted. Since the storage battery does not require a power supply line for operating the temperature sensor unit 200, the number of lines in the freezer warehouse 100 can be reduced. Further, the unit-side timekeeping device 240 has time data. The time data is associated with the temperature data detected by the internal temperature sensor 210. It is also used to periodically start the temperature sensor unit 200.

The unit-side control device 250 processes a signal related to the temperature detected by the plurality of internal temperature sensors 210.

The unit-side power supply unit 253 controls the power supply from the unit-side power supply device 230, and manages the power supply of the temperature sensor unit 200 and the internal temperature sensor 210. The unit-side power supply unit 253 periodically activates the temperature sensor unit 200 based on the timekeeping of the unit-side timekeeping device 240, and detects the temperature in the refrigerating warehouse 100. The unit-side data communication unit 254 sends a signal including data obtained by processing by the unit-side signal processing control unit 252 to the warehouse management device 1. Here, the unit-side data communication unit 254 wirelessly sends a signal to the warehouse management device 1. Therefore, it is not necessary to lay a communication line in the freezer warehouse 100, and the number of lines in the freezer warehouse 100 can be reduced. Further, here, the unit-side data communication unit 254 will be described as sending data to the warehouse management device 1, but the present invention is not limited to this. For example, it may be sent to a remote controller (not shown) of the freezer warehouse 100.

FIG. 4 is a diagram showing the configuration of the warehouse management device 1 according to the first embodiment of the present invention. Next, the warehouse management device 1 will be described. The warehouse management device 1 is a device that manages the freezer warehouse 100. Here, the warehouse management device 1 mainly manages the temperature in the freezer warehouse 100.

The management side communication device 20 receives a signal sent from an external device, and extracts data or the like to be processed by the management side control device 10. Further, the data processed by the management side control device 10 is included in the signal and sent to the centralized warehouse management device 500 via the public communication line 400.

Further, the management side input device 30 transmits data such as instructions and settings input by the user to the management side control device 10 as an input signal. Further, the management side display device 40 displays to the user based on the display signal transmitted from the management side control device 10.

The warehouse temperature determination unit 11 determines the temperature related to the detection of the warehouse temperature sensor 210 installed in the freezer warehouse 100. The value determination unit 12 determines the division value of the division 101 in the freezer warehouse 100 based on the temperature related to the detection of the internal temperature sensor 210. Here, the section value is a value, a grade, a price, or the like determined for the section 101 based on a predetermined standard. Here, it is assumed that the value is determined based on the temperature of the section 101. The criteria for parcel value are not particularly limited. For example, as described above, the temperature unevenness in the freezer warehouse 100 is large. Therefore, the smaller the temperature change with respect to the target temperature set for the compartment 101, the higher the compartment value can be. Further, when there is a temperature change due to the stoppage of the air-conditioning / cooling device 4, the section 101 having a large protection against luggage, such as a short time to return to the target temperature and a quick recovery, can be considered to have a high section value. ..

The device control unit 13 controls the operation of the air conditioning / cooling device 4 and the blower unit 9. Further, the luggage determination unit 14 reads data associated with the luggage from, for example, a tag attached to the luggage, and obtains data such as the size of the luggage and the cold storage temperature for the luggage carried into the freezer warehouse 100. get. The storage determination unit 15 determines a section 101 as a storage place in the freezer warehouse 100 for the cargo determined by the cargo determination unit 14. Then, as described above, an instruction is sent to the unit-side display device 220 corresponding to the determined section 101 to display the light emission. However, the present invention is not limited to this, and the storage location section 101 may be notified to a terminal or the like owned by the worker.

The billing determination unit 16 charges for the luggage stored in the section 101. Here, the method of charging by the charging determination unit 16 is not particularly limited, but for example, charging may be performed based on the division value of the division 101. Further, when it is difficult to maintain the lot value due to temperature unevenness or the like, charging may be performed based on the achievement rate of the lot value. Then, when the signal corresponding to the light emission of the unit side display device 220 is sent from the light receiving device 91, the deterioration prediction unit 17 predicts the deterioration of the unit side power supply device 230 based on the signal. Here, the deterioration prediction unit 17 predicts deterioration of the unit-side power supply device 230 based on the intensity of light emission of the unit-side display device 220, but is not limited to this. The voltage related to the power supplied by the unit-side power supply 230 is monitored, and when the voltage falls below the set threshold value, it is determined that the unit-side power supply 230 has deteriorated or is likely to deteriorate. You may.

Here, it is assumed that the management side control device 10 is composed of, for example, a microcomputer having a control calculation processing device such as a CPU (Central Processing Unit). Further, the management side storage device 50 is a volatile storage device (not shown) such as a random access memory (RAM) capable of temporarily storing data, a hard disk, and a non-volatile storage device such as a flash memory capable of storing data for a long period of time. It has an auxiliary storage device (not shown). The management-side storage device 50 has data as a program of processing procedures and the like performed by each unit of the management-side control device 10. Then, the control arithmetic processing unit executes the processing based on the data of the program and realizes the processing of each part. However, the present invention is not limited to this, and each device may be configured by a dedicated device (hardware).

FIG. 5 is a diagram illustrating a process performed by the management side control device 10 according to the first embodiment of the present invention. Here, an example of a process in which the value determination unit 12 determines the partition value will be described. The value determination unit 12 acquires the temperature data of the section 101 determined by the warehouse temperature determination unit 11 during the set period (step S1). Here, as for the data to be acquired, it is desirable that there are many data when the air in the freezer warehouse 100 is stable.

The value determination unit 12 extracts the maximum temperature and the minimum temperature from the acquired temperature data (step S2). Then, the value determination unit 12 determines whether or not the maximum temperature and the minimum temperature are included in the target temperature ± 1 [° C.] set in the section 101 (step S3). When the value determination unit 12 determines that the maximum temperature and the minimum temperature are included in the target temperature ± 1 [° C.], it determines that the section 101 is a prime location with the highest section value (step S4). End the process.

On the other hand, if the value determination unit 12 determines that the maximum temperature and the minimum temperature are not included in the target temperature ± 1 [° C.], the value determination unit 12 determines whether or not the maximum temperature and the minimum temperature are included in the target temperature ± 5 [° C.] (step S5). ). When the value determination unit 12 determines that the maximum temperature and the minimum temperature are included in the target temperature ± 5 [° C.], it determines that the section 101 is a secondary area (step S6), and ends the process. Then, when the value determination unit 12 determines that the maximum temperature and the minimum temperature are not included in the target temperature ± 5 [° C.], it determines that the section 101 is a tertiary land (step S7), and ends the process. do.

As described above, according to the warehouse management device 1 of the first embodiment, the space in the freezer warehouse 100 is divided into a plurality of sections 101. Then, the value determination unit 12 of the management side control device 10 has a value determination unit 12 that determines the division value of the division 101 based on the temperature related to the detection of the internal temperature sensor 210. Therefore, the inside of the freezer warehouse 100 can be valued for each section 101, and the temperature can be controlled based on the section value.

Embodiment 2.
FIG. 6 is a diagram showing a configuration of a centralized warehouse management device 500 in the warehouse management system 1000 according to the second embodiment of the present invention. In the second embodiment, the analysis of the data related to the warehouse management of the freezer warehouse 100 performed by the centralized warehouse management device 500 will be described. By performing analysis by the centralized warehouse management device 500, it is possible to grasp the situation of each freezer warehouse 100 and make proposals such as improvement. As shown in FIG. 6, the centralized warehouse management device 500 includes a data storage device 510, an analysis control device 520, and an analysis side communication device 530.

As described above, the data storage device 510 stores data related to warehouse management and the like. Further, the analysis side communication device 530 serves as an interface for signal communication between the public communication line 400 and the analysis control device 520. Further, the data processed by the analysis control device 520 can be included in the signal and sent to each warehouse management device 1 via the public communication line 400.

The analysis control device 520 of the centralized warehouse management device 500 of the second embodiment has a cooling capacity determination unit 521, an operation status determination unit 522, a replacement determination unit 523, and a centralized side deterioration prediction unit 524. The cooling capacity determination unit 521 determines the cooling capacity of the air-conditioning cooling / heating device 4 by comparing a certain freezing warehouse 100 with data related to warehouse management in another freezing warehouse 100. Further, the operation status determination unit 522 determines the operation status of a certain freezer warehouse 100 by comparing it with data related to warehouse management in another freezer warehouse 100. Further, the replacement determination unit 523 performs a determination process for the replacement of the air conditioning / cooling device 4 in the refrigerating warehouse 100. Further, the centralized side deterioration prediction unit 524 predicts the deterioration of the unit side power supply device 230, similarly to the deterioration prediction unit 17 of the management side control device 10 of the warehouse management device 1.

FIG. 7 is a diagram showing an example of data related to warehouse management stored in the data storage device 510 according to the second embodiment of the present invention. In FIG. 7, data in four freezer warehouses 100 (freezer warehouse 100A to freezer warehouse 100D) are shown. Here, in the second embodiment, the cooling space volume in the refrigerating warehouse 100, the power consumption, the temperature stability, the cooling capacity, the number of air-conditioning / cooling equipment 4, the model name and manufacturing year of the air-conditioning / cooling equipment 4, and the number of times the door is opened / closed. , The set temperature and the average outside air temperature are shown as parameters.

Next, the analysis and the proposal processing performed by the analysis control device 520 based on the data related to the warehouse management will be described. Here, the processing performed by the analysis control device 520 is an example. The cooling capacity determination unit 521 of the analysis control device 520 compares the data of each refrigerating warehouse 100 based on the data stored in the data storage device 510. For example, when the cooling capacity determination unit 521 compares the data of the freezer warehouse 100A to the freezer warehouse 100D shown in FIG. 7, the freezer warehouse 100A consumes less power per unit volume than the other freezer warehouse 100. It is judged that it is large and the temperature stability in the refrigerator is poor. Therefore, it is possible to make a proposal to increase the number of sections 101 in which the temperature is stable and increase the section value of the entire freezer warehouse 100.

Further, for example, when the cooling capacity determination unit 521 compares the data of the refrigerating warehouse 100A to the refrigerating warehouse 100D shown in FIG. 7, the refrigerating warehouse 100A has a small number of installed air-conditioning cooling devices 4 and has a unit volume. It is judged that the cooling capacity per area is low. Therefore, it is possible to make a proposal to increase the cooling capacity per unit volume or increase the number of air-conditioning cooling / heating devices 4. Efficiency is improved by setting the cooling capacity per unit volume and the number of air-conditioning cooling / heating devices 4 appropriately.

Here, for example, when the preconditions such as the average outside air temperature and the set temperature are different, it is advisable to correct the data and then perform the comparison between the freezer warehouses 100.

The operation status determination unit 522 of the analysis control device 520 also compares the data of each freezer warehouse 100 based on the data stored in the data storage device 510. By comparing the data of the freezer warehouse 100A to the freezer warehouse 100D shown in FIG. 7, the operation status determination unit 522 determines that the freezer warehouse 100A has a large number of door opening / closing times. Therefore, it is possible to make a proposal with reference to the operation of another freezer warehouse 100 (import / export schedule, etc.).

The replacement determination unit 523 of the analysis control device 520 compares the data of each refrigerating warehouse 100 based on the data stored in the data storage device 510. For example, the replacement determination unit 523 compares the data shown in FIG. 7, and determines that the refrigerating warehouse 100A is equipped with the air-conditioning / cooling device 4 having an older manufacturing year than the refrigerating warehouse 100B to the refrigerating warehouse 100D. Therefore, it is possible to propose replacement with the air-conditioning / cooling / heating device 4 whose manufacturing year is new.

The centralized side deterioration prediction unit 524 of the analysis control device 520 compares the data related to the deterioration of the unit side power supply device 230 stored in the data storage device 510, and predicts the deterioration of the unit side power supply device 230 installed in the freezer warehouse 100. I do. The centralized side deterioration prediction unit 524 may perform deterioration prediction by associating the time elapsed until the unit side power supply device 230 deteriorates with the temperature detected by the internal temperature sensor 210. This is because the deterioration of the storage battery of the unit-side power supply device 230 has a correlation with the temperature. As a result, deterioration prediction can be performed with high accuracy by comparing with the data of the internal temperature sensor 210 of the other freezer warehouse 100.

Here, the centralized warehouse management device 500 compares the data in each freezer warehouse 100 and analyzes the entire warehouse, but the present invention is not limited to this. The centralized warehouse management device 500 may perform analysis based on the data for each section 101. Then, by performing the analysis in each section 101, it is possible to make a proposal for improvement in each section 101. For example, for a certain section 101, the position of the section 101 in the refrigerating warehouse 100, the data on the air-conditioning / cooling device 4 corresponding to the section 101, and the like are compared and analyzed. Then, it is possible to make a proposal based on the analysis.

As described above, according to the warehouse management system 1000 of the second embodiment, the analysis control device 520 of the centralized warehouse management device 500 analyzes the data related to the warehouse management among the plurality of refrigerated warehouses 100 to be managed. I made it. Therefore, it is possible to compare between 100 freezer warehouses, and based on the determination result obtained by the comparison, it is possible to make proposals such as improvement of section value, operation, and replacement of equipment.
