Refrigerator Monitoring System

Abstract

The invention discloses a refrigerator monitoring system. The refrigerator monitoring system comprises an acquiring terminal, a center control box and a receiving display module, wherein the acquiring terminal is connected to a refrigerator, and is in wire connection with the center control box through a connecting end; the acquiring terminal transmits refrigerator data, acquired from the refrigerator, to the center control box for processing; and after a center controller of the center control box encodes the transmitted data according to a given protocol, the data is transmitted to the receiving display module of a monitoring center through an Ethernet or a CDMA mode for analyzing and displaying. The refrigerator monitoring system saves the labor, effectively improves the data transmission accuracy, and is convenient for users to monitor such parameters as temperature and humidity in the refrigerator in real time.

Description

technical field [0001] The invention relates to the field of data acquisition and monitoring, in particular to a monitoring system for a refrigerator. Background technique [0002] The refrigerated container transportation industry has developed extremely rapidly in recent years, especially in the Asia-Pacific region. A large amount of refrigerated goods are sent to all parts of the world every year, which makes the scale of reefer container yards in various distribution ports expand day by day. Most domestic ports use traditional data collection methods. After the reefers arrive at the site, the staff conducts inspections every 3 hours and records various data of the reefers case by case. Specifically, the traditional manual collection method requires a person to walk over each box, connect the serial communication interface provided on the control board of the refrigerator to the laptop with a data cable, and use the software of each brand of box to collect Data, and then...

Problems solved by technology

Specifically, the traditional manual collection method requires a person to walk over each box, connect the serial communication interface provided on the control board of the refrigerator to the laptop with a data cable, and use the software of each brand of box to collect Data, and then enter the collected data into the database. In this way, some data input errors will inevitably lead to inaccurate information and long data delays.

This method is slow in recognition speed, consumes a lot of manpower, has a high error rate, and cannot realize real-time tracking. In order to solve this problem, the present invention provides a data acquisition system capable of real-time monitoring of refrigerators
