Wired remote monitoring system and method for refrigerated container

Abstract

The invention discloses a wired remote monitoring system for a refrigerated container. The wired remote monitoring system contains a data acquisition terminal and a monitoring platform connected with the data acquisition terminal, wherein the data acquisition terminal contains a line concentration module at least connected with a digital serial port of one refrigerated container so as to acquire state parameters of the refrigerated container, a control module which is connected with the line concentration module and used for sending a control command to the refrigerated container, a buffer module which is connected with the control module and used for storing the state parameters, fed back by the refrigerated container, of the refrigerated container, a location module which is connected with the control module and used for acquiring geographical location information of the refrigerated container and a data transmission module which is connected with the control module and used for sending the state parameters and geographical location information of the refrigerated container to the monitoring platform and receiving the control command sent by the monitoring platform. The invention also discloses a wired remote monitoring method for the refrigerated container. The system and method which are disclosed by the invention are economical and practical, dismounting is convenient, and full coverage of monitoring of the refrigerated container is realized.

Description

technical field [0001] The present invention relates to a wired remote monitoring system and its method, in particular to a wired remote monitoring system and method for refrigerated containers, in particular to a wired remote monitoring system and its application for refrigerated containers on wharf yards and ocean-going cargo ships. method. Background technique [0002] Refrigerated containers must be managed according to the temperature specified by the cargo owner during the storage and transportation process, and regular inspections are required by dock operators and electricians on board. The traditional inspection method is that the inspectors carry the record book next to the refrigerator, or Record the temperature of each refrigerated container by climbing the ladder. If the transport temperature specified by the owner does not meet or the refrigerated container is found to be working abnormally, notify the relevant personnel to check and repair it. This kind of in...

Problems solved by technology

However, this system also has certain shortcomings in practical applications: since most reefer containers are not equipped with power line carrier modulators, even if the wharf or freighter is equipped with the REFCON system, it cannot achieve full coverage of reefer container monitoring. During the inspection process, the staff cannot determine which boxes are equipped with power line carrier modulators. Therefore, it is still necessary to manually go to the site for inspection one by one.

Even if all refrigerated containers of a shipping company are equipped with power line carrier modulators, in the actual transportation process, due to the need to transport refrigerated containers of other companies (similar to airline alliances, swapping positions), it will not be able to fully cover
