Description

 Ultra Low-Power ZigBee Wireless System for Refrigerated Containers Real-time Monitoring}

 The present invention is a new concept ultra low power wireless system capable of real-time monitoring of temperature and status information of a refrigerated container. Slave Terminal / Master with 2.4GHz ZigBee wireless communication and Real-Time Location System (RTLS) technology based on IEEE 802.15.4 standard The terminal and the intelligent monitoring control system. More specifically, based on the analysis of the protocols of the world's refrigerated container manufacturers, we developed a protocol that can be used universally and embedded it in the Slave Terminal to install 2.4GHz ZigBee wireless communication + RTLS Location tracking) function and RS-232C interface provided by refrigerated container to translate refrigerated container information such as temperature, alarm, and location information and transmit it to 2.4GHz ZigBee wireless communication to the master terminal to monitor the status of refrigerated container in the central control system. Ultra-low power wireless sheath for real-time monitoring Architecture relates to the structure and implementation.

  Frozen container cargoes may be deteriorated if they are not maintained at the proper temperature. Therefore, the condition of frozen containers should be monitored in real time to prevent the deterioration of frozen container cargo.However, due to the fact that the container is loaded with four or more layers, steel structure walls are formed. Is a difficult situation. Conventional refrigeration container management method is that a dedicated manager goes up a line over refrigerated containers stacked up to 4 floors of Deck and patrols all refrigerated containers three times every four hours a day to visually inspect the control panel information and when a panel problem occurs After repairing the refrigerated container, the procedure to prepare a refrigeration report and report it to the headquarters' equipment team was completed. If there were no problems with the panel, the monitoring logbook was forced to be managed. This inconvenience caused problems such as increased safety and management costs of management personnel due to increased volume of cargo, and reparation, reprocessing costs, and reduced credibility due to cargo deterioration. Therefore, there was a need to enable real-time monitoring by linking the refrigerated container systemically. The present invention has been made to improve the above-described problem, and an object thereof is to provide an ultra low power wireless system architecture structure and an implementation method capable of real-time monitoring of temperature and state information of a refrigerated container.

If the manufacturer uses different refrigeration containers, the protocol is different, and each terminal is directly connected to the refrigeration container and connected manually to read the status data from the data reader. Embedding in the terminal eliminates the inconvenience of managing the equipment separately according to the refrigeration container manufacturer.

This is a new concept of ultra low power wireless solution that can monitor the temperature and status of refrigerated container in real time.Integration with Slave Terminal / Master Terminal with 2.4GHz ZigBee wireless communication and Real-Time Location System (RTLS) technology based on IEEE 802.15.4 standard Commercialized solution that prevents compensation problems caused by cargo deterioration caused by shipper due to safety of the dedicated manager from sea accident and abnormal freezing container due to the management of frozen container status in real time through research and development of advanced monitoring control system

Ultra low power refrigerated container real-time monitoring solution using 2.4GHz ZigBee wireless communication technology based on IEEE 802.15.4 protocol that enables long-distance communication through power amplifier circuit and high antenna matching design as additional implementation technology considering container line

-Freight of refrigerated containers may be deteriorated if not maintained at the proper temperature, thus preventing problems such as reimbursement, reprocessing costs, and reduced credibility due to deteriorated refrigerated containers.

-Through the wireless communication technology, location tracking algorithm technology and intelligent monitoring service, it is possible to establish stable logistics system, such as container gate automation and container entry / exit processing, which greatly increases economic benefits and improves management and corporate competitiveness. Triggered.

-Reduce the risk of dedicated managers and eliminate the paper work required to manage refrigerated containers in a working environment where a dedicated manager must line up a refrigerated container stacked on Deck 4th floor and periodically check it three times every four hours per day.

-A dedicated manager regularly monitors the temperature inside the freezing container, but the safety and management costs of management personnel increase due to the increase in the volume of cargo. You can save.

-The real-time management of the refrigerated container with minimum personnel arrangement enables efficient personnel management and the prevention of precious human injury caused by ship accidents.

-Failure to proactively cope with sudden temperature changes caused by passive management prevents the problem of the responsible material studios due to the failure to identify the immediate cause and the exact cause of the change.

-The world's first commercialized solution, which has a real need for real time monitoring system for refrigerated containers of shipping companies around the world, is highly likely to enter the global market and can increase domestic and overseas visibility and sales.

Ultra-low-power system design that guarantees a battery life of at least one to two years, reducing the cost and time required to charge and replace batteries.

-It can provide the reliability and stability of ZigBee wireless communication service commercialization by inducing reception distance optimization through built-in power amplifier circuit and highly antenna matching design and applying reconnection algorithm in case of communication failure.

-If the manufacturer uses different refrigeration containers, different protocols can be used to connect the different terminals to read the status data from the data reader and the inconvenience of managing the equipment separately depending on the refrigeration container manufacturer.
