Description

The present invention relates to a detection processing unit attached to a package to be shipped, and a physical distribution management system that uses the detection processing unit to manage the incoming/outgoing conditions, the storage conditions, and the transportation environment conditions of a storage warehouse or the like. is.

In order to improve the efficiency of logistics and reduce mistakes, a service (warehouse management system) that conducts inspection management of incoming and outgoing shipments and warehouse inventory management by converting product code information into code images (recognition codes) and QR codes (registered trademark) has spread widely. (For example, Non-Patent Document 1).

On the other hand, for the purpose of quality control in logistics, sensors with wireless functions are attached to packages to measure data such as temperature, humidity, impact, tilt, illuminance, and position, and wireless gateways installed in trucks and warehouses. There is a known service (Transportation Status Visualization System) that attempts to ensure transport quality by grasping the impact of the transport environment on packages in real time by uploading data to the cloud via Document 1, Non-Patent Document 2).

The warehousing/delivery management system and the transportation status visualization system described above are separate systems because they use different information access methods. As shown in Patent Documents 2 and 3, a code image (recognition code image) affixed to a parcel is photographed by an installed network camera and used as information for a storage/retrieval management system, and at the same time, the appearance of the packing box is photographed. There is also a proposal to integrate the warehousing management system and the transportation status visualization system by obtaining information for the transportation status visualization system that judges the presence or absence of damage accidents from changes in the outer shape.

In addition, the data used in the conventional transportation situation visualization system is raw data output from sensors (for example, Patent Document 4). However, it is not possible to predict the possibility of damage to the package on the basis of technical grounds in the state of these raw data. Evaluations using evaluated damage boundary curves or damage boundary curves are not reflected. In package design, an impact measuring device is used, for example as disclosed in US Pat. This impact measuring device automatically and quickly measures maximum acceleration, action time, and velocity change by arithmetically processing test data.

If the cargo entry/exit management system and the transportation status visualization system are separate systems, there will be installation costs and operating costs for each, and it will be necessary to develop inter-system linkages. In addition, a system that visualizes the transportation situation by uploading raw data from sensors such as acceleration, temperature, humidity, etc. that cargo receives from the environment such as transportation and warehouse management to the cloud, reduces the possibility of sudden transportation accidents.

As shown in FIG. 2C, when the display section 14 and the power supply section 17 are arranged on different surfaces, the area of the front portion can be reduced. Each functional block provided on the circuit board 133 will be described in detail below.

The detection unit 11 includes an acceleration sensor 110 and a temperature/humidity sensor 111 . It should be noted that either the acceleration sensor 110 or the temperature/humidity sensor 111 may be provided.

The communication unit 12 performs wireless communication with a terminal device, a mobile terminal device, or the like. The communication unit 12 receives information such as parcel information 150, quality control information 152, and measurement setting information 151 from an external terminal device or the like. The above information can also be obtained from an output unit 18 (terminal unit), which will be described later. In this embodiment, as shown in FIG. 7A, by connecting a USB cable 29 between the USB terminal of the terminal device (personal computer) and the output section 18 (terminal section) of the detection processing unit 10, the above get information.

The configuration in which the communication unit 12 performs wireless communication by Bluetooth is not an essential configuration of the detection processing device 10 of the present invention, but in this embodiment, the communication unit 12 is configured to perform wireless communication by Bluetooth.

The package information 150 is information for identifying a transported item (package), such as product name, product number, serial number, dimensions, weight, handling precautions, etc. A specific example is shown in FIG. 6(A). FIG. 6A shows information on the product name "robot arm" as an example. The initial information of the quality control information 152 represents the initial state (state before transportation) of the transportation item, and is information as shown in FIG. 6(B). The measurement setting information 151 is a measurement method set by the user, and includes measurement mode, measurement start and end time, measurement interval, and control threshold (for example, to determine whether or not damage has occurred, the inherent damage boundary of the product as shown in FIG. 3). curve data is required). The damage boundary curve data is data specific to the product (packaged item), and as described above, the damage boundary curve uses the test evaluation method specified in the product impact strength test (JISZ0119) for packaging and product design. It was created using Also, in order to determine the presence or absence of dew condensation, for example, a dew point temperature conversion table (conversion table using the Sonntag equation and the Wagner-Pruss equation) as shown in FIG. 5 is required. Other dew point temperature conversion tables may be used.

In the storage unit 15, as shown in FIG. 7A, the terminal device and the output unit 18 are connected by a USB cable 29, and package information 150, quality control information 152, and measurement settings are written via serial communication (for example, UART). Information 151, information such as standard time is stored. The control unit 13 reads the standard time and corrects the system time of the detection processor 10 . Also, as shown in FIG. 8A, when the start button 160 is pressed after installation in the packing box 51, the three axes (X, Y, Z) of the initial value (DC value) of the acceleration sensor 110 are set to 0, respectively. and the initial values (initial temperature, initial humidity) of the temperature/humidity sensor 111 are stored. Note that the installation method shown in FIG. 8A is for making full use of the performance of the detection arithmetic processing unit 10, and for simple verification, it may simply be attached to the packaging box 51. FIG.

Also, as an example of measurement settings, when a management threshold is exceeded during a physical distribution process such as handling, transportation, or warehouse management of a package, the value is recorded and updated. Such information is information as shown in FIGS. 6(C) to 6(E), and includes detection values, notifications of warning (alert) information by arithmetic processing, and the dates and times of their occurrence.

The control unit 13 is composed of a CPU, a RAM, a ROM, etc., and functions as control, calculation, and storage means, and performs control of each functional block of the detection arithmetic processing device 10 and the entire device, arithmetic processing of detection data, and the like. In this embodiment, the storage unit 15 is referred to and the calculation unit 130 and the display control unit 131 are controlled. Note that part of the information stored in the storage unit 15 may be stored in the ROM 132 . Also, the control unit 13 has a system time, which is corrected to the standard time when communicating with a terminal device or mobile terminal.

The calculation unit 130 calculates the detection value detected by the acceleration sensor 110 and determines whether or not the damage boundary curve ( FIG. 3 ), which is the management threshold value stored in the storage unit 15 , is exceeded. Specifically, when a shock value exceeding the control threshold (TH) is detected during transportation, a waveform consisting of acceleration values sampled at all times, that is, a shock wave (acceleration waveform) as shown in FIG. The acceleration waveform is stored in the ROM and RAM 132, and as shown in FIG. 4B, the calculation unit 130 integrates the acceleration waveform to calculate the area, that is, the velocity change .DELTA.V (m/s). The time for integrating the acceleration waveform is, for example, the time from when the acceleration exceeds 5% to when it falls. If the control threshold is exceeded, it is determined that damage may occur. Note that the speed change is not limited to the method shown in FIG.

Further, the calculation unit 130 determines the possibility of overturning from the data detected by the acceleration sensor 110 . As described above, the transported object is installed along the three axes (X, Y, Z) of the box, and the initial acceleration values (DC values) of the three axes are set to 0 in the installed state. During operation, for example, whether or not there is a possibility of overturning is determined by whether or not any of the three axes continues ±1 G (gravitational acceleration value) for a predetermined time (several seconds) or longer. If any of X, Y, and Z continues at ±1 G for a predetermined time (several seconds) or longer, it is determined that there is a possibility of overturning. The calculation unit 130 may be configured to determine only the "possibility of occurrence of damage" as described above, or may be configured to determine the "possibility of occurrence of overturning" in addition to that. The present embodiment is configured to determine both possibilities.

Further, when the detection unit 11 includes the temperature/humidity sensor 111, the calculation unit 130 calculates detection values detected by the temperature/humidity sensor 111 as well as the acceleration sensor 110, and determines whether there is a possibility of dew condensation. to judge. The possibility of dew condensation on the object to be packed is determined by measuring the temperature and humidity while the object is packed and the temperature/humidity sensor 111 is installed (installed state), and calculating the dew point temperature using the dew point temperature conversion table in FIG. Calculate and store. If the temperature detected by the temperature/humidity sensor 111 falls below the dew point temperature during the physical distribution process during operation, it is determined that dew condensation may occur. For example, if the initial values are a temperature of 30° C. and a relative humidity of 70% rh, the dew point temperature is found to be 23.93° C. from the dew point temperature conversion table of FIG. If the temperature/humidity sensor 111 detects a temperature of 20° C. during storage in a warehouse, it is determined that dew condensation may occur (see FIG. 6(D)).

The display control unit 131 displays the parcel information 150 (identification information of the transportation item), the quality control information 152, and other device information as code images. In the initial state, a code image representing initial information of package information 150 and quality control information 152, information on the state of charge of power supply 117, etc. (see FIGS. 6A and 6B) is generated and displayed. Specifically, a one-dimensional code such as a bar code, a two-dimensional code such as a CP code and a QR code (registered trademark) are generated from the table (CSV data) in FIG. 6, and the generated code image is displayed on the display unit (electronic paper ) 14 for display. In this embodiment, as shown in FIG. 2A, a QR code is displayed (hereinafter the code image is abbreviated as QR code). A QR code is preferable as a code to be used in the detection processing unit 10 because it can store a large amount of data in a small space and is resistant to dirt and damage due to its error correction function.

Further, the display control unit 131 sequentially rewrites the initial information of the quality control information 152 to the latest information when a detected value or event to be stored occurs by calculation by the calculation unit 130 ((C) to (E) in FIG. 6). ), and generate and display QR codes sequentially. For example, if there is a possibility of damage occurring, a QR code indicating the quality control information 152 rewritten to the warning information is generated and displayed. The displayed QR code is read at any time by the camera function of mobile terminals such as smartphones, tablets, handy terminals, and QR code readers.

The display section 14 displays the QR code sent from the display control section 131 . A thin display device such as a liquid crystal display (LCD), an organic EL display (OELD), and an electronic paper display (EPD) can be applied to the display unit 14 . In this embodiment, an electronic paper display is used, which has a feature (image retention property) that a displayed picture remains as it is even after the battery is exhausted. In this embodiment, as described above, the display section 14 is attached to the upper surface of the circuit board 133 (FIG. 2(C)). The QR code displayed on the electronic paper display is retained until the next update, during which time it consumes almost no power, and the display is maintained even if the power is turned off. Even if 117 becomes empty, it is possible to read package information from the display unit 14 . FIG. 6(E) shows the quality control information 152 until just before the battery runs out, but the QR code containing that information and the parcel information 150 continues to be displayed on the display unit 14 even after the battery runs out.

While the display unit 14 outputs visual information in this way, it may also be configured to output sound information at the same time. For example, when the calculation by the calculation unit 130 determines that the detected value is in a warning state, a function of not only displaying the QR code to which the information is added but also outputting a warning sound may be provided.

The switch section 16 (input section) can be switched on and off, and power is supplied from the power supply section 17 to each functional block of the circuit board 133 when the switch section 16 is on. When using, the user turns on the switch section 16 to operate the detection processor 10 . The switch section 16 may use any method such as a push button type or a slide type as long as it can be switched on and off. In this embodiment, as shown in FIG. 2(A), a start button 160 and an end button 161 are provided. It may be configured to start and end with one button.

A power supply 117 supplies power to each functional block of the detection processing unit 10 . The power source 117 may use a dry battery, which is a so-called primary battery, or a rechargeable battery, which is a secondary battery. In this embodiment, a thin rechargeable lithium polymer battery that is used in batteries for mobile phones, notebook computers, mobile devices, and the like is used. In this embodiment, as described above, the power supply 117 is attached to the bottom surface of the circuit board 133 (FIG. 2(C)).

The output unit 18 (terminal unit) connects the terminal device 20 with a USB cable to charge the power supply unit 17 and to transmit information (package information 150, initial information of quality control information 152, measurement setting information 151) to the detection processing unit 10. etc.) and a terminal (USB terminal) for acquiring measurement data stored in the storage unit 15 of the detection processing unit 10 .

The detection arithmetic processing device 10 is configured as described above. Since the detection processing unit 10 is configured as described above, it is possible to cause damage, overturning, or dew condensation to occur during the distribution process, which cannot be detected only from the detection data (raw data) from the sensor. It is possible to quickly grasp the possibility of occurrence of logistics accidents.
