Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. However, the attached drawings are provided solely to more easily disclose the contents of the present invention, and those skilled in the art will readily understand that the scope of the present invention is not limited to the scope of the attached drawings.

Additionally, the terminology used in this application is solely for the purpose of describing specific embodiments and is not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly dictates otherwise.

In this application, terms such as “include” or “have” are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

Figures 1 and 2 illustrate a cold chain device (hereinafter, “cold chain device”) capable of identifying a delivery abnormality according to an embodiment of the present invention. Figure 3 illustrates a cold chain system according to another embodiment of the present invention.

As illustrated in FIGS. 1 to 3, a cold chain device (100) according to an embodiment of the present invention includes a power supply unit (110), a control unit (130), a first communication module (150), a second communication module (170), and a display unit (210).

The power supply (110) supplies energy required for the operation of the cold chain device (100) according to an embodiment of the present invention. The power supply (110) may include a disposable battery or a rechargeable battery.

The control unit (130) operates on energy supplied from the power supply unit (110). The control unit (130) is configured to receive sensing information from the sensing unit (140) that senses the environmental conditions of the storage space where the shipment is stored and to determine whether the sensing information is within a normal range or an abnormal range.

The control unit (130) may include a memory. The memory may store sensing information collected periodically or aperiodically, along with time information. For this purpose, the control unit (130) may further include a timer (not shown).

The sensing unit (140) may include a sensor capable of sensing at least one of temperature, humidity, illuminance, vibration, position, and gas, but the present invention is not limited thereto.

The cold chain device (100) according to an embodiment of the present invention may include a sensing unit (140) as shown in FIG. 1, or the sensing unit (140) may be provided on the outside of the cold chain device (100) according to an embodiment of the present invention as shown in FIG. 2.

When the sensing unit (140) is provided outside the cold chain device (100) according to an embodiment of the present invention, the cold chain device (100) according to an embodiment of the present invention may include a communication interface unit (190) for receiving sensing information from the sensing unit (140). The communication interface unit (190) may be connected to the sensing unit (140) by wire or wirelessly.

A storage space may be a space for storing shipments while they are in transit or being prepared for transit. For example, the storage space may be a bag, container, or cooler, but the present invention is not limited thereto.

Shipments can deteriorate, be damaged, or be deformed depending on the environmental conditions of the storage space. For example, shipments containing pharmaceuticals, fresh produce, high-precision devices, or plants can be significantly affected by the temperature and humidity of the storage space. Therefore, the shipping company must ensure that the storage environment is suitable for the shipment.

When the sensing information is within the normal range, the first communication module (150) is configured to transmit the sensing information to the electronic device (300) of the delivery person under the control of the control unit (130) using energy supplied from the electronic device (300) of the delivery person.

The first communication module (150) may include an NFC (Near Field Communication) module or an RF (Radio Frequency) module.

The first communication module (150) can perform a transmission operation by receiving at least a portion of the energy required for transmitting sensing information from the electronic device (300) of the transmitter. In addition, the first communication module (150) can also receive a portion of the energy required for the operation of the first communication module (150) from the power supply unit (110).

For example, if the first communication module (150) is an NFC module, in the process of tagging the NFC module of the smartphone of the delivery person to the NFC module of the first communication module (150), the NFC module of the smartphone of the delivery person can transmit a signal of 13.56 MHz to the NFC module of the first communication module (150). The NFC module of the first communication module (150) can receive energy from the smartphone of the delivery person through electromagnetic induction according to the signal and transmit sensing information to the smartphone of the delivery person.

The electronic device (300) of the delivery person may be a smartphone, a dedicated terminal, a tablet PC, a laptop computer, a wearable computing device (e.g., a smart watch, smart glasses, HMD, etc.), but the present invention is not limited thereto.

The electronic device (300) of the delivery person may be installed with a delivery app or delivery application to support a cold chain device (100) according to an embodiment of the present invention and a cold chain system according to another embodiment of the present invention described later.

The electronic device (300) of the delivery person may include a first communication module (150), a second communication module (170), and a communication means for communicating with the delivery management server computing device (500). For example, if the first communication module (150) is an NFC module or an RF card module, the electronic device (300) of the delivery person may include the NFC module or the RF card reading module or be connected to enable communication therewith.

Additionally, if the second communication module (170) is a Bluetooth module, the electronic device (300) of the delivery person may include a Bluetooth module that can pair and connect with the second communication module (170).

The electronic device (300) of the delivery person may include at least one of a wired LAN module, a Wi-Fi module, and a mobile communication module to communicate with the delivery management server computing device (500), but the present invention is not limited thereto.

If the sensing information is within the normal range, the second communication module (170) stops operating under the control of the control unit (130). To this end, the control unit (130) may block the energy of the power supply unit (110) from being supplied to the second communication module (170) or convert the state of the second communication module (170) to a power saving mode.

In addition, when the sensing information is in an abnormal range, the second communication module (170) is configured to transmit the sensing information in the abnormal range to the electronic device (300) of the delivery person using energy supplied from the power supply unit (110) under the control of the control unit (130). The abnormal range may be outside the normal range, or may be a specific range that is not in the normal range.

For example, the second communication module (170) may include a BLE (Bluetooth Low Energy) module. When sensing information in an abnormal range occurs, the control unit (130) supplies power to the power supply unit (110) to the BLE module or releases the power saving mode, and the BLE module may transmit the sensing information in the abnormal range to the electronic device (300) of the delivery person in the form of a Bluetooth beacon signal.

When the electronic device (300) of the delivery person receives sensing information in an abnormal range, the electronic device (300) of the delivery person may output alarm information. The alarm information may have at least one form of visual information, auditory information, or tactile information.

The display unit (210) is configured to display whether the sensing information falls within a normal range or an abnormal range under the control of the control unit. The display unit (210) may include an LED, LCD, or OLED, but the present invention is not limited thereto.

Fig. 5 illustrates an example of a display state of a display unit (210). As illustrated in Fig. 5, the sensing information may include at least one of temperature, humidity, and vibration. The display unit (210) may display at least one piece of information corresponding to a normal range and at least one piece of information corresponding to an abnormal range.

In Fig. 5, the abnormal range may include not only the temperature outside the allowable delivery temperature range, but also the degree of temperature deviation from the normal range, such as “delivery temperature outside the allowable delivery temperature range 5℃.”

Additionally, the color of the light emitted from the display unit (210) may change depending on the type of sensing information. For example, as illustrated in FIG. 5, the light emitted for temperature may be red, and the light emitted for humidity and vibration may be blue. Furthermore, when temperature, humidity, and vibration are all within normal ranges, the light emitted may be green.

At this time, the blinking speed of the light emitted may vary depending on whether the information falls within the normal range or the abnormal range. For example, as illustrated in Fig. 5, when temperature, humidity, and vibration fall outside the acceptable range, i.e., fall within the abnormal range, the light emitted may blink slowly or rapidly.

In this way, through changes in the color and flashing speed of the emitted light, the shipper can quickly visually identify the environmental conditions of the storage space. Furthermore, the shipper can visually identify the type and status of sensors that are out of the normal range through the display unit (210).

As described above, if the sensing information is within the normal range, the operation of the second communication module (170) is stopped, and the first communication module (150) can transmit the sensing information through energy supplied from the electronic device (300) of the delivery person. In addition, if the sensing information is within the abnormal range, the second communication module (170) can operate, and the sensing information within the abnormal range can be transmitted to the electronic device (300) of the delivery person.

In this way, the sensing information is transmitted through the first communication module (150) and the second communication module (170) that are divided depending on whether the sensing information is within the normal range or the abnormal range, and the first communication module (150) transmits the sensing information through energy supplied from the electronic device (300) of the delivery person rather than the power supply unit (110) of the cold chain device (100), so the efficiency of the power supply unit (110) of the cold chain device (100) can be increased.

The first communication module (150) can receive energy from the electronic device (300) of the delivery person during the tagging process with the electronic device (300) of the delivery person. For example, if the first communication module (150) is an NFC module, the electronic device (300) of the delivery person can tag with the NFC module, and during the tagging process, energy from the electronic device (300) of the delivery person can be transferred to the NFC module, so that sensing information within a normal range can be transmitted to the electronic device (300) of the delivery person through the first communication module (150).

In this way, the first communication module (150) transmits sensing information within a normal range using energy transmitted from the electronic device (300) of the transmitter, and the operation of the second communication module (170) is stopped, thereby increasing the efficiency of the power supply (110).

Unlike the present invention, when sensing information of normal range and abnormal range are transmitted through the same communication module, power must be continuously supplied to the communication module to transmit the sensing information, so the efficiency of the power supply unit (110) may decrease.

In addition, since the first communication module (150) transmits sensing information within a normal range through tagging with the electronic device (300) of the delivery person, the communication distance of the first communication module (150) can be within 10 cm.

In addition, since the second communication module (170) must transmit sensing information in an abnormal range to the electronic device (300) of a delivery person driving a delivery vehicle (e.g., a two-wheeled vehicle, a four-wheeled vehicle, etc.) or performing delivery work, the communication distance of the second communication module (170) may be 5 m or more and 50 m or less.

The control unit (130) can receive sensing information before the start of transmission of sensing information through the first communication module (150) at the request of the electronic device (300) of the delivery person and transmit the sensing information to a gateway (400) installed in a fixed location through the second communication module (170).

For example, as illustrated in FIG. 4, when the delivery program of the electronic device (300) of the delivery person sets the start of delivery according to the operation of the delivery person and the electronic device (300) of the delivery person tags the cold chain device (100), the control unit (130) of the cold chain device (100) can start transmitting sensing information to the electronic device (300) of the delivery person through the first communication module (150).

However, during the pre-delivery preparation process, the shipment and cold chain device (100) may be held in a warehouse. Since the shipment may deteriorate, deform, or be damaged depending on environmental conditions during the delivery preparation process, sensing information that can confirm the environmental conditions may be continuously transmitted to the delivery management server computing device (500).

As previously explained, the transmission of sensing information through the first communication module (150) is accomplished through energy transmitted from the electronic device (300) of the delivery person. However, during the delivery preparation process, since the delivery person has not received the delivery item, tagging of the electronic device (300) of the delivery person may not be performed.

Accordingly, the control unit (130) can transmit sensing information to a gateway (400) fixedly installed in a warehouse or the like through the second communication module (170), and the gateway (400) can store sensing information on a shipment waiting for delivery in a delivery management server computing device (500).

At this time, the delivery management server computing device (500) can receive not only sensing information but also identification information of the cold chain device (100) from the cold chain device (100).

While the above description assumes that the space where a shipment is waiting for delivery is a warehouse, the present invention is not limited thereto. For example, the waiting space may be an empty lot, and the gateway (400) may be secured to a vertical bar, etc.

The control unit (130) can receive sensing information from the sensing unit (140) at set intervals and accumulate the sensing information. For example, the control unit (130) can receive sensing information from the sensing unit (140) at intervals of 10 minutes, 30 minutes, or 1 hour and continuously store the sensing information for each interval in memory.

The control unit (130) can transmit the accumulated sensing information to the electronic device (300) of the delivery person through the first communication module (150) at the request of the electronic device (300) of the delivery person.

For example, when a delivery person delivers a package to a customer, the delivery program of the delivery person's electronic device (300) may set the delivery end according to the delivery person's operation. When the delivery person's electronic device (300) with the delivery end set tags the cold chain device (100), the control unit (130) may transmit all sensing information accumulated in the memory to the delivery person's electronic device (300).

In addition, since sensing information about the shipment is no longer needed after delivery of the shipment, the control unit (130) can stop storing the sensing information after transmission of the accumulated sensing information is completed. This can increase the efficiency of the power supply unit (110).

Unlike the present invention, when the electronic device (300) of the delivery person receives and accumulates sensing information from the cold chain device (100) at set intervals, the sensing information must be received through the second communication module (170), so the power consumption of the cold chain device (100) may increase.

Next, a cold chain system according to another embodiment of the present invention will be described.

A cold chain system according to another embodiment of the present invention includes one or more cold chain devices (100), a delivery device's electronic device (300), and a delivery management server computing device (500).

Since the cold chain device (100) has been described in detail above, its description is omitted.

The electronic device (300) of the delivery person receives sensing information within the normal range and sensing information within the abnormal range. Since the electronic device (300) of the delivery person has been described in detail above, a detailed description thereof will be omitted.

The delivery management server computing device (500) is configured to receive sensing information within a normal range and sensing information within an abnormal range from the electronic device (300) of the delivery person and store the sensing information for each cold chain device (100).

The delivery management server computing device (500) and the delivery person's electronic device (300) can perform server-client communication.

The delivery management server computing device (500) can receive and store the identification information of the delivery item and the identification information of the cold chain device (100) mapped to each other from the manager's electronic device (700).

The manager's electronic device (700) may be a smartphone, tablet PC, laptop computer, desktop computer, or wearable computing device (e.g., smart watch, smart glasses, HMD, etc.), but the present invention is not limited thereto.

The manager's electronic device (700) may be connected to a device (e.g., a barcode reader or QR code scanner) for reading the identification information of the shipment. For this purpose, a barcode or QR code may be displayed on the surface of the shipment or its storage space. While the barcode or QR code corresponding to the identification information of the shipment has been exemplified above, the present invention is not limited thereto.

Depending on the input unit manipulation by the administrator, identification information (e.g., serial number or identification code) of the cold chain device (100) may be input into the administrator's electronic device (700). The input unit may be, but is not limited to, a keyboard, mouse, stylus pen, touch panel, touch display, barcode reader, QR code scanner, etc.

The manager's electronic device (700) can also map the delivery person's identification information with the delivery item's identification information and the cold chain device's identification information (100) and transmit the information to the delivery management server computing device (500). The delivery person's identification information may include the delivery person's name, employee number, photo, etc., but the present invention is not limited thereto.

After delivery begins, the electronic device (300) of the delivery person can transmit sensing information of normal and abnormal ranges to the delivery management server computing device (500), and accordingly, the delivery management server computing device can match the sensing information transmitted from the electronic device (300) of the delivery person with the identification information of the delivery item and the identification information of the cold chain device (100) and store them.

At this time, in order to match the sensing information, the delivery management server computing device (500) can search for the delivery person's identification number transmitted from the delivery person's electronic device (300). If the delivery person's identification number transmitted from the delivery person's electronic device (300) is searched among the information stored in the delivery management server computing device (500), the delivery person's identification number and the mapped delivery person's identification information can be matched with the sensing information.

Accordingly, the delivery management server computing device (500) can match and manage sensing information for one or more deliveries delivered by the delivery person.

When the start of delivery for each delivery item is set in the delivery program installed in the electronic device (300) of the delivery person, the delivery management server computing device (500) can receive delivery start information and sensing information for each delivery item from the electronic device (300) of the delivery person.

For example, when a delivery person operates his/her electronic device (300) and a delivery program installed in the electronic device sets the start of delivery, the electronic device (300) of the delivery person tags one or more cold chain devices (100), so that the electronic device (300) of the delivery person can receive sensing information for each delivery item from the electronic device (300) of the delivery person.

At this time, a single cold chain device (100) may collect sensing information for a single shipment. Furthermore, a single cold chain device (100) may collect sensing information for multiple shipments as needed. For example, if multiple shipments are of the same type, and the environmental conditions required by the multiple shipments are identical, the multiple shipments may be placed in a single storage space, and the sensing unit (140) may sense the environmental conditions of the single storage space.

The electronic device (300) of the delivery person can confirm that delivery has started by transmitting delivery start information and sensing information for each delivery item to the delivery management server computing device (500).

When the end of delivery for each delivery item is set in the delivery program installed in the electronic device (300) of the delivery person, the delivery management server computing device (500) can receive delivery end information for each delivery item and sensing information for each delivery item from the electronic device (300) of the delivery person. The sensing information for each delivery item according to the delivery end information may be sensing information accumulated from the start of delivery to the end of delivery.

For example, during the process of delivering a shipment to a customer, the delivery program installed in the electronic device (300) of the delivery person may set the end of delivery for each shipment according to the operation of the delivery person, and then the electronic device (300) of the delivery person may tag the cold chain device (100).

Accordingly, the electronic device (300) of the delivery person can receive sensing information accumulated from the start of delivery of the delivery item to the end of delivery from the cold chain device (100) and transmit the accumulated sensing information to the delivery management server computing device (500).

At this time, the accumulated sensing information may include sensing information within the normal range and sensing information within the abnormal range. Furthermore, the accumulated sensing information may further include information indicating the time at which the delivery person's electronic device (300) received the sensing information from the cold chain device (100). Accordingly, history management of sensing information for each shipment can be achieved.

The above has been described for the start and end of delivery, but between the start and end of delivery, if necessary, the electronic device (300) of the delivery person can receive sensing information by tagging the cold chain device (100), and transmit the received sensing information to the delivery management server computing device (500).

The cold chain device (100) can receive sensing information before transmission of the sensing information via the first communication module (150) at the request of the electronic device (300) of the delivery person and transmit the sensing information to a gateway (400) installed in a fixed location via the second communication module (170). Since this has been described in detail above, a detailed description thereof will be omitted.

When the electronic device (300) of the delivery person receives sensing information of an abnormal range from one or more cold chain devices (100), the electronic device (300) of the delivery person can match the location information derived from the location tracking module equipped in the electronic device (300) of the delivery person with the sensing information of the abnormal range and transmit it to the delivery management server computing device (500).

In the case of a cold chain device (100), since it may be difficult to obtain power efficiency or location information from a satellite, the location tracking module of the electronic device (300) of the delivery person may be used.

The positioning module may support at least one of the GPS system, the BeiDou system, and the Galileo system, but the present invention is not limited thereto.

As described above, embodiments of the present invention have been described. It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope thereof, in addition to the embodiments described above. Therefore, the above-described embodiments should be considered illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description, but may be modified within the scope of the appended claims and their equivalents.
