Description

Monitoring system of smart frozen container}

The present invention relates to a system for monitoring the temperature management status of refrigerated containers used to transport cargo. More specifically, the temperature inside the cargo compartment where fresh cargo is stored, the operating status of the air conditioning system, and whether the cargo compartment door is opened are monitored. It is about a monitoring system that continuously monitors and automatically notifies the manager when a problem is discovered during the monitoring process so that a prompt response can be implemented.

In general, refrigerated containers equipped with air-conditioning devices that can create a low-temperature environment inside are used for storage or long-distance transportation of fresh cargo that requires maintaining a frozen or refrigerated temperature.

Fresh cargo stored in such refrigerated containers requires continuous monitoring because it can easily deteriorate and lose its value as a product. However, with the existing manual monitoring method by managers, loopholes can occur at any time in management. A problem arises.

Therefore, rather than using a manual monitoring method, it is recommended to use an automatic monitoring device or system that can automatically monitor the temperature management status of the refrigerated container. In relation to this, see the Korean Patent Publication No. 10-1336999, “Real-time wireless of refrigerated containers.” Inventions such as “Monitoring Device” and “IoT-based Container Monitoring System” in Republic of Korea Patent Publication No. 10-2020-0079367 have been proposed and disclosed.

In other words, the “Real-time wireless monitoring device for refrigerated containers” in the Republic of Korea Patent Publication No. 10-1336999 collects operating status information of refrigerated containers in real time and provides it to managers in various ways, so that not only real-time monitoring is possible, but also operational. An invention has been proposed regarding a real-time monitoring device that can save energy by significantly reducing required power consumption.

In addition, the “IoT-based container monitoring system” in Republic of Korea Patent Publication No. 10-2020-0079367 allows checking history information according to the location movement of the container, checks the temperature and humidity information inside the container, and locks the container. An invention has been proposed regarding a monitoring system that allows checking the status.

However, since the above-mentioned prior inventions are generally configured to use only environmental information such as temperature information and humidity information in monitoring the internal state of the container, it is difficult for managers to respond quickly in situations where an air conditioning device malfunctions. It happens.

In other words, there may be a significant time difference depending on various factors such as the external environment from the time when the cooling device installed in the container malfunctions to the time when the temperature inside the container rises in earnest, so it is important to monitor the condition inside the container by using temperature information and humidity. Methods that only use environmental information, such as information, have limitations in the configuration that inevitably result in significant delays in the administrator's response from the time an actual problem occurs.

Therefore, there is a need to supplement the problems described above, and furthermore, there is a need for an invention regarding a system that can monitor the status and location of refrigerated containers in a more efficient manner.
