Embodiment Construction

[0020] The present invention mainly adopts the following technical methods in the specific implementation process:

[0021] Combined with Figure 1, the function of the microcontroller in the system is to receive the status signal of the controlled object (cold box temperature, etc.) through the sensor, and then control the compressor and other refrigeration equipment according to the predetermined program to ensure that the status of the cold box meets Control requirements.

[0022] Combined with Figure 2, in order to test a faulty microcontroller that was removed from a refrigerated container on site and returned to the laboratory, it is necessary to provide a simulated operating environment for the microcontroller. The controller provides a flexible and convenient simulated operating environment of various working conditions of the cold box, and realizes the test of the performance and failure phenomenon of the microcontroller. Subsequently, the database in the fault diagno...

Abstract

The invention discloses a fault diagnosis system for refrigerated container microcontroller including a computer that is configured with PLC as input / output interface, and connects with I / O interface board through PLC and CPU board of the tested microcontroller. It establishes a refrigerated container software model and expert analysis system in the computer, to simulate various operating conditions of the refrigerated container, and automatically conduct a comprehensive test on running state and fault nature of microcontroller, providing the test data to the expert system for a specific assessment, and automatic generating the test result and maintenance written report.

Description

Technical field [0001] The invention relates to a refrigerated container microcontroller, in particular to a refrigerated container microcontroller fault diagnosis system. Background technique [0002] In recent years, the container transportation industry, as the core industry of modern logistics, is developing rapidly with each passing day. Among them, refrigerated container storage and transportation is a kind of high-profit and high-risk container storage and transportation. It needs reliable support of high technology in order to effectively avoid high risks and obtain high profits. The core of the control system of the refrigerated container adopts advanced microcomputer controller (microcontroller for short) technology to ensure the best storage and transportation conditions for storing and transporting (valuable) goods in the refrigerated container. This kind of microcontroller has good performance, but it is difficult to maintain the circuit board (such as CPU boar...
