As shown in Figure 1, the cold chain integrated monitoring system 1 according to the present invention includes a monitoring device 100, a server 200, and a user terminal 300.

According to the present invention, the monitoring device 100 is connected to a cooler in the cooling room and monitors the cooling room. Here, the cooling room refers to a refrigerated container, a refrigerated tower installed in a vehicle, etc. Accordingly, the monitoring device 100 may be installed in a refrigerated container or a refrigerated tower vehicle. At this time, the cooler refers to a device that controls the temperature of the cooling chamber. The cooler may include a temperature sensor and a humidity sensor.

In one embodiment, there may be a plurality of monitoring devices 100. Each monitoring device 100 can monitor each of a plurality of cooling chambers.

In one embodiment, the monitoring device 100 can control the cooler. Specifically, the monitoring device 100 can control the cooler according to the control command from the server 200.

Hereinafter, the monitoring device 100 will be described in more detail with reference to FIG. 2.

Figure 2 is a diagram showing the configuration of a monitoring device according to an embodiment of the present invention.

The monitoring device 100 according to the present invention may include a GPS module 110, a control module 120, and a communication module 130, as shown in FIG. 2.

The GPS module 110 may generate location data indicating the location where the monitoring device 100 is installed. The GPS module 110 can transmit location data to the server 200 through the communication module 130.

The control module 120 can control the cooler by inputting control commands to the cooler. At this time, the control module 120 may receive a control command from the server 200 through the communication module 130 and input the received control command to the cooler.

For example, when the server 200 transmits a first control command to set the temperature of the cooler to the first temperature, the control module 120 inputs the first control command to the cooler to set the set temperature of the cooler to the first temperature. It can be set to . Accordingly, the cooler can be operated according to the set temperature according to the control command.

For example, when the server 200 transmits a second control command to turn on the cooler, the control module 120 can input the second control command to the cooler to turn on the cooler. Additionally, when the server 200 transmits a third control command to turn on the cooler, the control module 120 can input the third control command to the cooler to turn off the cooler.

The communication module 130 can perform transmission and reception with the cooler. Accordingly, the communication module 130 can collect temperature data and humidity data from the cooler.

Additionally, the communication module 130 can perform transmission and reception with the server 200. Accordingly, the communication module 130 can transmit temperature data and humidity data to the server 200 and receive control commands for controlling the cooler from the server 200.

Meanwhile, the monitoring device 100 may further include a camera module. The camera module can generate product images by photographing the interior of the cooling room. At this time, the camera module may be installed separately from other components of the monitoring device 100 inside the cooling chamber, and the product image generated by the camera module is transmitted to other components of the monitoring device 100 through the communication module 130. It can be delivered.

When following this embodiment, the communication module 130 can transmit the generated product image to the server 200.

Here, the communication module 130 is a configuration for communicating with various external devices, and is not only connected to external devices through a local area network (LAN) and the Internet, but also through wireless communication (e.g. , Z-wave, 4LoWPAN, RFID, LTE D2D, BLE, GPRS, Weightless, Edge Zigbee, ANT+, NFC, IrDA, DECT, WLAN, Bluetooth, Wi-Fi, Wi-Fi Direct, GSM, UMTS, LTE, WiBRO, etc. It can be connected to an external device through a communication method or a wired communication method (eg, USB, HDMI, MHL, etc.). The communication module 130 may include various communication chips such as a Wi-Fi chip, a Bluetooth chip, and a wireless communication chip.

Referring again to FIG. 1, the server 200 can determine whether an event occurs during the transportation of the cooling room using temperature data, humidity data, and location data collected by the monitoring device 100.

To this end, the server 200 can use the product image received from the monitoring device 100 to check the product loaded in the cooling chamber. In one embodiment, the server 200 may confirm the product loaded in the cooling chamber by comparing the product image with information on the product loaded in the cooling chamber. Product information may be stored in advance and may include a standard product image, product to be loaded, product type, etc. At this time, the product type may include livestock products, agricultural products, pharmaceuticals, etc.

For example, the server 200 may compare the product image with a reference product image to determine whether there is an abnormality in the product loaded in the cooling chamber.

In one embodiment, the server 200 may determine that an event occurred during the transportation process when the product loaded in the cooling room is different from product information.

For example, if the product image and the reference product image are different, the server 200 may determine that the product loaded in the cooling room is different from the product to be loaded. If the product image and the reference product image match more than a predetermined standard value, the server 200 may determine that the product loaded in the cooling room is the same as the product to be loaded. The server 200 may determine that there is a problem with the product if the products are different, and determine that there is no problem with the product if the products are the same.

If it is determined that there is no problem with the product loaded in the cooling room, the server 200 can determine whether an event occurs during the transportation process of the cooling room using the reference data mapped to the corresponding product information. Here, the reference data may include reference temperature data, reference humidity data, reference position data, etc. Accordingly, the reference data may be mapped to product information and stored in advance.

In one embodiment, the server 200 may determine whether the temperature of the cooling chamber is abnormal by comparing temperature data with preset reference temperature data.

In one embodiment, the server 200 may determine that the temperature of the cooling room is abnormal when the temperature data deviates from the reference temperature data for a predetermined period of time.

For example, the server 200 determines that if the temperature data is 0°C, the predetermined time is 5 minutes, and the reference temperature data is -5°C, if the temperature data is maintained at 0°C for more than 5 minutes, the temperature of the cooling room is set to 0°C. It can be judged that there is something wrong.

In one embodiment, the server 200 may compare humidity data with preset reference humidity data to determine whether the humidity in the cooling room is abnormal.

In one embodiment, the server 200 may determine that the humidity in the cooling room is abnormal when the humidity data deviates from the standard humidity data for a predetermined period of time.

For example, the server 200 determines that if the humidity data is 70%, the predetermined time is 5 minutes, and the standard humidity data is 90%, if the humidity data remains at 70% for more than 5 minutes, the humidity in the cooling room is abnormal. It can be judged that there is.

In one embodiment, the server 200 may determine whether the location of the cooling chamber is abnormal by comparing the location data with preset reference location data.

In one embodiment, the server 200 may determine that the location of the cooling room is abnormal when the location data deviates from the reference location data at a predetermined point in time.

For example, if the location data is the first location and the reference location data is the first location at the first point in time, the server 200 may determine that the location of the cooling chamber is normal. Additionally, the server 200 may determine that the location of the cooling chamber is abnormal when the location data is the first location and the reference location data is the second location at the second time point.

In one embodiment, the server 200 is configured to open the cooling chamber when the rate of change of the temperature data and the rate of change of the humidity data are greater than or equal to a predetermined reference value, and if the rate of change of the temperature data is a positive rate of change and the rate of change of the humidity data is a negative rate of change. It can be judged that In addition, the server 200 may determine that the cooling chamber is open when the rate of change of temperature data and the rate of change of humidity data are greater than or equal to a predetermined reference value, and if the rate of change of temperature data is a negative rate of change and the rate of change of humidity data is a positive rate of change. there is.

In this way, the reason why the rate of change of temperature data and the rate of change of humidity data are different depending on whether the cooling room is opened or closed is because the temperature of the cooling room is maintained lower than that of the outside, while the humidity is maintained higher than that of the outside due to the temperature difference between the inside and outside. am.

In one embodiment, when the server 200 determines that an event has occurred during transportation in at least one of the plurality of cooling chambers, it sends a message about the event to the user terminal 300 that manages the cooling chamber. can be created and transmitted.

For example, if it is determined that the cooling room temperature is abnormal, a message containing temperature abnormality information can be generated and transmitted to the user terminal 300 that manages the cooling room.

In one embodiment, the server 200 may generate a control command to control the cooler according to an event that occurs. The server 200 transmits the generated control command to the monitoring device 100, and when the monitoring device 100 receives the control command, it can control the cooler by inputting the received control command to the cooler.

For example, the cold chain integrated monitoring system can generate a control command that causes the cooler to operate at the reference temperature if the temperature of the temperature data is abnormal.

In one embodiment, the server 200 generates a control command to increase the set temperature of the cooler from the reference temperature to the heating temperature at predetermined intervals, and changes the set temperature of the cooler from the heating temperature to the reference temperature after a predetermined time. You can create a control command that lowers to . This is to remove frost around the cooler, as frost may form around the cooler while it is operating, which may cause damage to the cooler.

In one embodiment, the server 200 may generate a control command to adjust temperature and humidity according to the transportation schedule of the corresponding product. At this time, the transportation schedule may be stored in advance in the server 200. Here, the transportation schedule may include a transportation period, reference point, temperature control value, humidity control value, etc. At this time, the reference point refers to the point in time when at least one of temperature and humidity changes.

In one embodiment, the server 200 may generate a control command to gradually adjust temperature and humidity at each predetermined reference point.

For example, if the product is beef and the transportation schedule is 3 days, the first temperature and first humidity on the first day, the second temperature and second humidity on the second day, and the third temperature and third humidity on the third day. , the server 200 may generate a control command to adjust the temperature and humidity of the cooling room to the first temperature and the second humidity on the first day, and adjust the temperature and humidity of the cooling room to the second temperature and the second humidity on the second day. 2 A control command can be generated to adjust the humidity, and on the third day, a control command can be generated to adjust the temperature and humidity of the cooling room to the third temperature and third humidity.

In one embodiment, the server 200 may generate transportation data by accumulating temperature data, humidity data, and location data. The server 200 may transmit the generated transportation data to the user terminal 300.

In one embodiment, if the location data matches the pre-stored departure location data, the server 200 determines that transportation has started and generates transportation start data, and the destination location data for which the location data is pre-stored. If it matches, it is determined that transportation has been completed and transportation completion data can be generated. Here, the transport completion data may include the transport time from the start of transport to the point of transport completion.

In one embodiment, the server 200 determines the quality maintenance of goods loaded in the cooling room using the rate of change of temperature data and humidity data, the cumulative distance of location data, and the transportation time of transportation completion data. It can be calculated. Here, the rate of change of temperature data may be the average value, mode, maximum value, etc. of the rate of change from when transportation start data is generated until transportation completion data is generated. The rate of change of humidity data may be the average value, mode, maximum value, etc. of the rate of change from when transportation start data is generated until transportation completion data is generated. The cumulative distance of location data may refer to the distance from when transportation start data is generated until transportation completion data is generated.

Specifically, the server 200 can calculate the quality maintenance degree of the product according to Equation 1 below.

Here, the first weight, second weight, and third weight may be set differently depending on the type of product.

For example, in the case of meat that is sensitive to temperature and humidity, the first weight for the rate of change of temperature data and the second weight for humidity data may be set larger than the third weight for cumulative distance/transportation time. Additionally, in the case of temperature-sensitive medicines, the first weight for the rate of change of temperature data may be set larger than the second weight for humidity data and the third weight for cumulative distance/transportation time. Additionally, in the case of agricultural products where rapid distribution is important, the third weight for cumulative distance/transportation time may be set larger than the first weight for temperature data and the second weight for humidity data.

The server 200 may transmit the quality maintenance level to the user terminal 300.

In this way, the present invention has the effect of allowing the server 200 to calculate the quality maintenance rate and provide it to the user, thereby not only managing the quality of frozen or refrigerated products, but also improving the reliability of the transportation process. .

In one embodiment, the server 200 may relay transportation orders. Specifically, the server 200 may match a first user requesting transportation of an article requiring cooling with a second user performing transportation of the article. For example, the server 200 may match a plurality of first users and a plurality of second users.

The server 200 receives a transportation request from the first user.

In one embodiment, when a transportation request occurs from a first user, the server 200 may preferentially match the transportation history score of the second user performing the transportation. For example, when a transportation request occurs from at least one first user among a plurality of first users, the server 200 will preferentially match the second user with the highest transportation history score calculated in advance among the plurality of second users. You can. For example, if A's transportation history score among second users is 10 and B's transportation history score is 20, the server 200 may preferentially match B with the first user who requested transportation.

Here, the server 200 can calculate the transportation history score using Equation 2.

Here, the lowest quality maintenance degree means the lowest quality maintenance degree calculated in a first predetermined period. The highest quality maintenance degree means the highest quality maintenance degree calculated in a first predetermined period. The first period refers to the period from the current matching time to the first time in the past. The weight based on experience can have a larger value the higher the transportation experience.

As such, the reason why the transportation history score according to the present invention is calculated using the quality maintenance degree is that, unlike general products, products requiring cooling are highly likely to deteriorate during the transportation process, and if carelessness occurs during the transportation process, the product This is to match only users who can handle items that require cooling, as there is a special characteristic of having to discard the entire item, not just a part of it.

Meanwhile, the user terminal 300 can transmit and receive data from the server 200. The user terminal 300 may provide data received from the server 200 to the user through a connection means such as an application or program distributed by the server 200.

In the present disclosure, the user terminal 300 may be, for example, a personal computer (PC) or laptop equipped with a wired Internet connection and browsing function, a laptop or mobile terminal equipped with a wireless LAN/mobile Internet connection and browsing function, or a mobile terminal. It may include a personal communication system (PCS), a global system for mobile (GSM) terminal, a personal digital assistant (PDA), or a smart phone equipped with a communication network connection and browsing function.
