1 and 2, the integrated control system for a refrigerated reefer container and a container-mounted special vehicle according to the present invention requires that a driver on board a special vehicle such as a truck equipped with a container (a reference number is omitted) Omitted) Using the portable smart device 300 so that it can be moved and managed individually, through this, when the driver reaches a specific container and is located, status information including the temperature and humidity of the container is automatically generated on the screen. Since this is accumulated and data is accumulated, it is possible to more conveniently manage temperature and humidity history data. In addition, it is also possible to check the real-time location of the delivery vehicle and the delivery section through means such as GPS.

The smart device 300 includes a smart phone, a tablet PC, a personal digital assistant (PDA), a notebook, a cellular phone, a personal communication service (PCS) phone, a hand-held PC, and a global system for mobile (GSM). )Phone, W-CDMA (Wideband CDMA) phone and CDMA-2000 phone, etc. are available, and you can download and use a dedicated application that can manage cold chains or run an existing built-in application.

Referring to FIG. 2, the overall configuration of the integrated control system for refrigerated refrigerated containers and container-mounted special vehicles of the present invention largely includes a wireless communication terminal 100, a repeater 200, a smart device 300, and a server 400. .

The wireless communication terminal 100 is installed on one side of the container to wirelessly communicate with the smart device 300 carried by the driver when the driver reaches the corresponding container, and the container status information including the temperature and humidity of the container Is transmitted to the dedicated application of the smart device 300. Therefore, it would be desirable to install a sensor (not shown) inside the container so that the container recognizes it when the smart device 300 held by the driver approaches.

The wireless communication terminal 100 includes a temperature sensor (not shown), a humidity sensor (not shown), and an MCU module (not shown) to calculate temperature and humidity values to measure the temperature and humidity of the container, It comprises a wireless communication module (not shown) for transmitting the calculated temperature value and humidity value to the server 400 or the like. For reference, the wireless communication terminal 100 is assigned a unique number for each terminal, and the unique number may be assigned as an address value of a special vehicle (vehicle registration location, etc.) or a container.

For reference, FIG. 3 is a diagram showing a communication protocol between the wireless communication terminal 100 and the server 400. This is a scenario of operation of TCP/IP and SMS communication between the wireless communication terminal 100 and the server 400. This is a design of a data packet structure transmitted from the wireless communication terminal 100.

The wireless communication terminal 100 is coupled with a wireless sensor (not shown) and can store data inside the container in real time even in a shaded area where the wireless communication network is disconnected. By retransmitting the internal temperature data stored in the flash memory in real time, it is possible to monitor the overall temperature change of the contents inside the container being transported. The communication network of the wireless sensor uses an ISM band (Industrial Scientific Medical Band: a frequency band usable in industrial, scientific, and medical devices), and has an advantage of enabling wireless communication even if there are obstacles such as walls of containers and concrete.

For reference, the range of the frequency band is 423 to 444 MHz (FM frequency), and 433 MHz is most preferable.

Therefore, when data is transmitted from the wireless communication terminal 100, the server 400 can determine which container the data is transmitted from through the unique number (eg, unique ID) of the wireless communication terminal 100, and Save data separately

For example, the wireless communication terminal 100 may use a Bluetooth 40 communication method. The Bluetooth 40 allows a certain driver to check the container status through wireless communication with the smart device 300 without going through a separate pairing process with the smart device 300 (a procedure for confirming a predetermined password when connecting devices to Bluetooth). You can see if it has been monitored. Here, it should be clarified in advance that the communication method of the wireless communication terminal is not limited to a specific method.

The repeater 200 is located in a special vehicle and receives status information including the location of the container, temperature, and humidity from the wireless communication terminal 100 and transmits it to the server 400 or the smart device 300. Therefore, it is preferable that the repeater 200 includes a temperature and humidity database (not shown) for storing a record of the temperature and humidity inside the vehicle at that time.

When the driver reaches the location of the container, the smart device 300 receives the location and status information of the container from the repeater 200 and installs a dedicated application that can monitor the internal condition of the container according to the temperature and humidity values. It is done.

Accordingly, the driver inputs and checks the date monitored by the smart device 300, the condition of the container, etc., and operates and manipulates the smart device 300 by checking the container requiring temperature and humidity adjustment. Alternatively, you can set or change the humidity so it can be individually adjusted.

The smart device 300 transmits the monitored date and the like to a corresponding driver database (not shown) of the server 400, and the server 400 receives and stores it. In addition, the server 400 receives the container location and status information (temperature, humidity, etc.) from the repeater 300 at a predetermined period (eg, 1 week, 15 days), and updates and stores it.

4 is a diagram illustrating a module configuration diagram implemented in a dedicated application of the smart device 300. Referring to this, the dedicated application of the smart device 300 includes a manager information input module 310, a temperature display and setting module 320. , A humidity display and setting module 330, a notification module 340, a container location map generation module 350, and a monitoring result input module 360.

The manager information input module 310 is a module that enables information of the manager (driver) in charge including the driver's name, rank, visit date, etc. to be input, and stores information of the manager (driver) managing the container on a specific day. Create an input window so that you can input.

The manager information input module 310 allows input of information of a responsible driver to record which driver visited on a specific date and whether the driver assigned the task checked the current temperature and humidity conditions of the container. Make it possible to clarify where the driver is responsible for monitoring on that date.

In the above case, it is not limited to the driver, and an employee who is in charge of a separate task (for example, a passenger in a special vehicle) may also be okay.

The temperature display and setting module 320 displays a temperature value inside the container, and enables setting and changing temperature states including low temperature, ice temperature, and freezing conditions.

The humidity display and setting module 330 displays the humidity value inside the container, and allows the humidity value to be set and changed. In this way, by providing accurate information acquired through an independent measurement module and sensor, it is possible to fundamentally prevent a worker's temperature manipulation.

The notification module 340 vibrates the unique number of the container and the status of the container when the standard temperature value and standard humidity value for each container are stored for a certain period of time out of a preset error range, and an alarm method and a notification message. , A push message, and a Kakao Talk form to notify the driver's smart device 300 in any one form.

The special vehicle location map generation module 350 generates a location value by GPS using the smart device 300, receives a signal from the wireless communication terminal 100 installed for each container provided on the tower, and receives the signal in the divided area. Create a layout diagram of all installed containers. Therefore, it is possible to accurately check the status and analysis of the real-time location of the section currently being delivered.

Therefore, it is possible to easily manage the driving record and improve the accuracy of data by analyzing the location where the special vehicle frequently moves.

It can be connected to storage means such as USIM and USB memory, and it is a structure in which power is supplied from a lithium-ion battery by using a charger in the voltage range of 4.2 to 12V.

The server 400 has a configuration including a driver database (not shown) and a container database (not shown).

The driver database is interlocked with the smart device 300 to store driver information, such as an ID of a driver, a driver's name, and a job title, of a driver in the vehicle.

The container database stores the unique number of the container recognized through the unique number of the wireless communication terminal 100. Therefore, the data of the container's temperature and humidity history is stored and recorded.

When the driver database and the data of the container database are combined and matched, information on which driver monitored the container can be generated, which is performed by a dedicated application. That is, the wireless communication terminal 100, the smart device 300, and the server 400 communicate with each other through a wireless network network including a 3G network and a Wi-Fi network. As communication using the currently established 3G network and wifi network for such a mobile environment, real-time monitoring of the container and information and management of the condition can be performed stably and smoothly without the need to establish a separate communication system.

The server 400 continuously stores the driver's ID, the container's unique ID, the date when the driver monitors the container, and the container status information, and transmits it to a central control system (not shown) for collective management. And to be used to operate. Accordingly, the wireless communication terminal 100 formed in the container in the special vehicle and the measured information can be recorded and managed in real time, and can be provided to an administrator when necessary.
