[ However, not all of the components shown in Fig. 1 are essential components of the computing device 11. [ The computing device 11 may be implemented by more components than the components shown in FIG. 1 and the computing device 11 may be implemented by fewer components than the components shown in FIG.

Here, the wireless signal may include various types of data depending on a voice call signal, a video call signal, or a text / multimedia message transmission / reception.

A communication circuit for receiving broadcasts receives broadcast signals and / or broadcast-related information from outside through a broadcast channel. The broadcast channel may include a satellite channel and a terrestrial channel. Depending on the implementation, the computing device 11 may not include communication circuitry for broadcast reception.

Communication circuitry 410 receives data from a plurality of sensor tags in the plant. Each sensor tag collects and transmits the identification information of the sensor tag, the current process information of the container to which the sensor tag is attached, the peripheral equipment information, and the surrounding environment information.

Or communication circuitry 410 may receive the above described information from a sensor tag reader (not shown) that collects data from a plurality of sensor tags in the plant, may receive the aforementioned data collected in an external server in real time have.

The communication circuitry 410 provides the received information to the processor 420.

The processor 420 controls the overall operation of the computing device 11. For example, the processor 420 may control components within the computing device 11 by executing instructions stored in the memory 430. Meanwhile, the processor 420 may include a single core, a dual core, a triple core, a quad core, and cores thereof. In addition, the processor 420 may include a graphics processing unit for graphics processing corresponding to the video. The processor 420 may be implemented as a SoC (System On Chip) in which a core and a GPU (not shown) are integrated.

In addition, the processor 420 may be implemented including a plurality of processors. For example, the processor 420 may be implemented as a main processor and a sub processor operating in a sleep mode.

Processor 420 determines the process flow for producing the product. For example, the computing device 11 further includes a user interface device (a touch pad, a keypad, a button, a joystick, a mouse, etc.) for inputting raw material information, and receives raw material information through a user input unit . Processor 420 may determine the process flow corresponding to the input raw material information. At this time, the process flow and the transportation flow information corresponding to the raw material information may be stored in the form of a table in the internal memory 430 of the computing device 11 or an external database (not shown). In the latter case, the processor 420 communicates with the external database through the communication circuit 410 as the raw material information is input, and can receive the process flow corresponding to the raw material information.

Thereafter, the processor 420 performs a first operation mode for monitoring the process corresponding to the process flow and a second operation mode for tracking the occurrence of the failure in the transportation process of the product produced by the process flow . At this time, the processor 420 may sequentially perform the first operation mode and the second operation mode for each product by using the sensor tag attached to the container carrying the result of each process and the product included in the process flow.

First, when the process is started, the processor 420 operates in the first operation mode. The processor 420 is periodically provided with the current process information, peripheral equipment information, and peripheral environment information of the container from the sensor tag 12. The processor 420 determines whether the current process information of the container matches the process flow and whether a failure has occurred with respect to the peripheral equipment based on the current process information, the peripheral equipment information, and the surrounding information.

For example, the processor 420 receives the identification information of the facility adjacent to the container received from the sensor tag 12, the supply voltage value of the facility, the current value, the temperature value, and the like, , Whether the current process information of the container matches the predetermined process flow, and whether the failure has occurred. For example, when the process flow defines (A process) -> (process B) -> (process C) and the process equipment required in each process, Based on the identification information of the process in question. Thereafter, when a fault occurs in step (D), the processor 420 outputs notification information indicating that a fault has occurred in step (D), or outputs the notification information to the plant management system (for example, facility control system or central control system) (D process), a failure occurrence message indicating that a failure has occurred can be transmitted. The processor 420 may also collect information received from the sensor tag 12 in a time-series manner to monitor whether or not the container is progressing sequentially through each process in the process flow.

In addition, the processor 420 may monitor the fire risk of the plant based on the temperature around the power line provided from the sensor tag 12 and the like. In addition, the processor 420 may receive a temperature value, a humidity value, and the like of the container provided from the sensor tag 12 to determine whether a failure (or alteration) of at least one product contained in the container occurs.

In addition, the processor 420 may receive identification information and status information of the products (or components) contained in the container provided from the sensor tag 12, and may monitor whether each product has failed.

Processor 420 switches the first mode of operation to the second mode of operation once the shipping flow is complete. In addition, the processor 420 may control the communication circuitry 410 to transmit an operation mode switching signal to the sensor tag 12.

Upon switching to the second mode of operation, the processor 420 waits until the end of the transportation process of the product. The probability of failure of the product during transportation decreases compared to the process. Also, it may be necessary to provide the computing device 11 in a transportation means (vehicle, ship, aircraft, etc.) to which the container is delivered, or to equip equipment for receiving data from the sensor tag 12 in real time. That is, in terms of power usage and economics, it is unnecessary for the computing device 11 to constantly monitor the transportation process.

Therefore, in the second operation mode, after the transportation process is completed, the processor 420 receives the environmental information history of the container recorded in the sensor tag 12 and tracks whether a product has failed in the transportation process . At this time, the surrounding environment information history may be the temperature / humidity information of the container recorded in a time-series manner, and may be the information labeled with the event information by the sensor tag 12. The processor 420 tracks occurrence of a failure of the container based on the temperature / humidity information exceeding the reference value and the duration information of the ON / humidity information exceeding the reference value. If the processor 420 determines that a failure has occurred, the processor 420 may output a warning message warning the possibility of failure of the product in the container (i.e., possibility of alteration) or send a warning message to the plant management system.

The memory 430 stores at least one instruction for processing and control of the processor 420 and includes identification information of each sensor tag received by the communication circuit 410, current process information of the container of each sensor tag, Equipment information and surrounding environment information. Further, the memory 430 may further store information on the process flow and the transportation flow corresponding to the raw material information.

The memory 430 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., SD or XD memory), a RAM (Random Access Memory) SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory) , An optical disc, and the like.

FIG. 5 is a time-wise diagram illustrating the operation of the computing device 11 and the sensor tag 12 according to an embodiment of the present invention.

Referring to FIG. 5, the raw materials are contained in a container 510a that moves through each process according to a process flow. At this time, the sensor tag 12 attached to the container 510a is turned on and operates in the first sensor mode. On the other hand, the computing device 11 starts the first operation mode as the process flow corresponding to the raw material is determined.

The sensor tag 12 receives the voltage value, the current value, and the temperature value of the facility from the facility abnormality detection sensor 520 attached to the facility located around the container 510a and the power line temperature detection sensor 530 located around the power line, Ambient temperature values, and the like. Also, the sensor tag 12 can sense the temperature / humidity value around the container 510a.

The sensor tag 12 periodically transmits information received from the peripheral sensors and information sensed by the sensor tag 12 in response to the wake-up signal transmitted by the computing device 11 or the sensor tag reader. Since the container 510a moves in accordance with the process flow, the information to be transmitted can be changed according to the process (and / or the position) in which the container 510a is being operated.

Computing device 11 may monitor the process flow based on information received from sensor tag 12 in a first mode of operation.

When the process is completed, the computing device 11 transmits an operation switching signal to the sensor tag 12. [ Accordingly, the sensor tag 12 switches the first sensor mode to the second sensor mode. However, the present invention is not limited thereto. The sensor tag 12 may further include a user interface device (e.g., a button, a key, etc.) for receiving a user input for switching modes, The first sensor mode may be switched to the second sensor mode.

Meanwhile, the product may be contained in the container 510a used in the process and delivered to the customer, but may be transferred to a new container 510b for delivery. In this case, the sensor tag 12 may be moved and attached to the new container 510b for unified management of the process and transportation of the product. For convenience of explanation, in the present invention, a container having one sensor tag 12 is described as being the same. However, the scope of the present invention includes a case where one sensor tag is attached to a different container. Can be easily understood.

The sensor tag 12 periodically senses the surrounding information of the container 510b in the second sensor mode and records the information during the transportation period.

In the second mode of operation, the computing device 11 waits until the transportation process is completed. Thereafter, when the transportation process is completed, the computing device 11 receives the environmental information history recorded during the transportation period. At this time, the surrounding environment information history may be temperature / humidity information recorded in a time-series manner during the transportation period. The computing device (11) tracks the possibility of deterioration of the product based on the environmental information history.

As described above, the product production and transportation management system 10 can easily manage the obstacles that may occur in the transportation process of producing one product and the transportation process of delivering the produced product by using the sensor tag.

6 is a diagram illustrating an operation method of a product production and transportation management system according to an embodiment of the present invention. The operation method of the product production and transportation management system 10 shown in Fig. 6 relates to the embodiment described in Figs. 1 to 5 and the like described above. Therefore, even if omitted below, the contents described above in Figs. 1 to 5 can also be applied to the operation method of Fig.

Referring to FIG. 6, the computing device 11 determines a shipping flow (s601). For example, the computing device 11 may determine the transportation flow based on the raw material information input to the computing device 11. For example, At this time, the transportation flow information corresponding to the raw material information can be stored in the form of a table inside or outside the computing device 11.

The computing device 11 initiates a first mode of operation as the process flow begins (s602).

On the other hand, as the process flow starts, the sensor tag 12 operates in the first sensor mode (s603). For example, the sensor tag 12 may be attached to a container containing the raw material and turned on by the user, thereby operating in the first sensor mode. Alternatively, the sensor tag 12 may operate in the first sensor mode according to an operation start signal provided from the computing device 11, but is not limited thereto.

Then, the sensor tag 12 detects current process information, peripheral equipment information, and surrounding environment information of the container to which the sensor tag 12 is attached (s604). The sensor tag 12 directly detects the surrounding information through the internal sensor, and may collect information sensed by the external sensor. At this time, the sensor tag 12 can collect information sensed by other sensors by performing close communication with other sensors adjacent to the container.

For example, the sensor tag 12 may receive information about at least one of the equipment identification information, the supply voltage value, the current value, and the temperature value from the equipment abnormality detection sensor adjacent to the container. Also, the sensor tag 12 can receive the power line ambient temperature value and the like from the power line fire monitoring sensor adjacent to the container.

The sensor tag 12 transmits the sensed information (s605). For example, the sensor tag 12 may transmit sensed information in response to a wake up signal received from the computing device 11 or a sensor tag reader (not shown).

The computing device 11 monitors the process corresponding to the process flow based on the information received from the sensor tag 12 (s606). Specifically, the computing device 11 determines whether the current process information of the container matches the process flow, based on the current process information, the peripheral equipment information, and the surrounding information received from the sensor tag 12, Determine whether a fault has occurred.

For example, the computing device 11 receives the identification information of the facility adjacent to the container received from the sensor tag 12, the supply voltage value of the facility, the current value, the temperature value, and the like, And determine whether the current process information of the container matches the predetermined process flow and whether the failure has occurred.

In addition, the computing device 11 may receive the power line ambient temperature value received from the sensor tag 12, etc., and monitor the fire risk of the plant. Also, the computing device 11 may receive the temperature value, the humidity value, etc. of the container received from the sensor tag 12 to determine whether a failure (or alteration) of at least one product contained in the container occurs.

Also, the computing device 11 may receive identification information and status information of at least one product contained in the container from the sensor tag 12, and may monitor whether or not each product has failed.

Steps s604 and s605 described above are repeatedly performed while the first operation mode is continued. Thus, the product production and transportation management system 10 can easily identify the failed process and product.

Thereafter, when the process flow is completed, the computing device 11 switches the first operation mode to the second operation mode (s607). The computing device 11 transmits an operation mode switching signal to the sensor tag 12.

The sensor tag 12 changes the first sensor mode to the second sensor mode in response to the operation mode switching signal (s609).

In the second operation mode, the sensor tag 12 is attached to the container for delivering the product, and records the surrounding environment information of the container (s610). The transportation means (vehicle, ship, aircraft, and the like) to which the container is delivered may not be provided with a device for communicating with the sensor tag 12 such as the computing device 11, external sensor, or the like. Thus, the sensor tag 12, in the second sensor mode, does not perform the operation to communicate with the computing device 11, other sensor or sensor tag, thereby reducing power consumption. Alternatively, the sensor tag 12 may record the temperature / humidity information of the container sensed by the temperature / humidity sensor inside the sensor tag 12. [

Then, when the transportation process is completed, the computing device 11 (or the sensor tag reader) transmits a wake-up signal to the sensor tag 12. [ In response to the wake-up signal, the sensor tag 12 transmits the recorded peripheral environment information history (s611).

The computing device 11 tracks whether a failure has occurred in the product based on the environmental information history (s612). The computing device 11 compares the ambient environment information history with the reference value, and extracts the surrounding environment information exceeding the reference value. Further, based on the extracted surrounding environment information, it is tracked whether or not the container has failed. For example, the computing device 11 receives the temperature / humidity information history of the container, and detects the temperature / humidity of the container based on the on / humidity value exceeding the reference value and the duration information of the on / You can trace whether or not.

When the computing device 11 determines that a failure has occurred in the product, the computing device 11 may output a warning message warning the possibility of failure (i.e., possibility of alteration) of the product in the container or send a warning message to the plant management system.

Meanwhile, in step s610, the sensor tag 12 may label values exceeding the reference value as event information from among the sensed surrounding environment information. In this case, in step s612, the computing device 11 may receive the environment information history labeled with the event information. Accordingly, the computing device 11 may skip the operation of comparing the ambient environment information history received from the sensor tag 12 with the reference value.

On the other hand, in the above description, steps s601 to s612 may be further divided into additional steps or combined into fewer steps, according to an embodiment of the present invention. Also, some of the steps may be omitted as necessary, and the order between the steps may be changed.
