Embodiment 1

[0044] Such as figure 1 As shown, in this embodiment, a railway cold chain transport electric refrigerated container monitoring system is provided, including a temperature and humidity sensor, an oxygen concentration detector, a fresh air system, an MCU processor, and a central remote control terminal installed in the central control room; wherein,

[0045] The MCU processor is connected with the cold machine controller of the electric refrigerated container to receive the parameter information about the cold machine operation of the electric refrigerated container sent by the cold machine controller, and send the information to the cold machine controller Send cold machine control command;

[0046] The MCU processor is connected with the battery management system BMS of the electric refrigerated container, to receive the battery operating parameter information about the electric refrigerated container sent by the BMS, and send a battery control command to the BMS;

[0047] T...

Embodiment 2

[0072] In this embodiment, a method for controlling electric refrigerated containers for railway cold chain transportation is provided, based on the system in the first embodiment, see figure 2 , the method includes:

[0073] S101. Receive the humidity parameter information in the refrigerated space of the electric refrigerated container collected and sent by the temperature and humidity sensor and the oxygen concentration information in the refrigerated space of the electric refrigerated container collected and sent by the oxygen concentration detector;

[0074] S102. Based on the humidity parameter information and oxygen concentration information, determine whether the humidity meets a preset humidity value and whether the oxygen concentration meets a preset oxygen concentration value;

[0075] S103. If the humidity does not meet the preset humidity value and / or the oxygen concentration does not meet the preset oxygen concentration value, send a control command to the fresh...

Embodiment approach

[0079] As an optional implementation, the method also includes:

[0080]The fresh air system is controlled to operate intermittently according to a preset time interval, so as to perform ventilation in the refrigerated space of the electric refrigerated container. Ventilation in the refrigerated space can be carried out regularly to ensure freshness. Among them, the preset time interval can be set according to the ventilation needs in the refrigerated space and the exhaust air volume of the fresh air system, as long as the oxygen and carbon dioxide concentrations in the refrigerated space meet the freshness preservation standards.

Abstract

The invention discloses an electric refrigerated container monitoring system and method for railway cold chain transportation. The system comprises a temperature and humidity sensor, an oxygen concentration detector, a fresh air system, an MCU (microprogrammed control unit) processor and a central remote control terminal mounted in a central control chamber, wherein the MCU processor is connectedwith a refrigerator controller of an electric refrigerated container; the MCU processor is connected with a BMS (battery management system) of the electric refrigerated container; the MCU processor isconnected with the temperature and humidity sensor and the fresh air system, and the central remote control terminal is wirelessly connected with the MCU processor. Basic operation state monitoring required for refrigeration of the pure electric refrigerated container and safety is realized, freshness and safety of refrigerated articles are guaranteed, attention of people on scene is not required, demands of long-distance transportation of a railway cold chain are sufficiently met, the whole monitoring can be completed in the central control chamber, the transportation efficiency and transportation safety of articles of a cold chain are improved, and the system is safe and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of electric refrigerated containers, in particular to a monitoring system and method for electric refrigerated containers for railway cold chain transportation. Background technique [0002] With the rapid development of China's economy and the continuous improvement of people's living standards, the total amount of food and goods that need to be transported in the cold chain is also increasing. However, the current railway refrigeration equipment is far from meeting the needs of my country's refrigerated cargo transportation. The developed series meets the market demand. The new type of railway refrigerated transport equipment is imminent. [0003] In order to adapt to the development of today's information technology, the use of pure electric refrigerated containers as a new type of railway refrigerated transportation equipment can improve transportation efficiency, and is safe and environmentally friendly....
