Problems solved by technology

[0003] The biggest problem for system operation and management is to find and eliminate faults. The purpose of this invention is to overcome the shortcomings of using circuit board invisible wiring to eliminate faults in the actual operation of the existing refrigeration and air-conditioning skills assessment, and propose a large and medium-sized refrigeration and air-conditioning system. The computer-aided maintenance simulation system of the project does not need to manually set up and troubleshoot in the assessment circuit, which is convenient for the examination of the fault simulation and fault resolution process of large and medium-sized refrigeration and air-conditioning systems

Abstract

The invention discloses a computer-aided overhaul simulation system for large and medium refrigeration and air-conditioning engineering, which comprises a computer, an I / O input / output module, an electronic switch driving module and an electric control circuit fault simulation module of a large and medium refrigeration and air-conditioning system, wherein the fault simulation module comprises the electric control circuit of the large and medium refrigeration and air-conditioning system and a fault electronic switch arranged in each arranging point of the control circuit; and the computer sequentially drives each fault electronic switch to be turned on and turned off through the I / O input / output module and the electronic switch driving module. In the invention, each fault electronic switch is controlled to be turned on and turned off by compiling software for the computer, fault setting and removal of the electric control circuit of the large and medium refrigeration and air-conditioning system are realized, and the electric control circuit of the large and medium refrigeration and air-conditioning system in the fault simulation module is the same as or similar to a real circuit. Training and examination contents are determined by the computer software, the examination results are automatically assessed by the computer, information management of the setting and removal of the faults is carried out by the computer, and the examination is just, fair and efficient.

Description

Technical field: [0001] The present invention relates to the technical field of refrigeration and air-conditioning, and in particular to a computer-aided maintenance simulation system for large and medium-sized refrigeration and air-conditioning projects. The system is mainly used for the actual operation, maintenance, repair and operation management training of large and medium-sized refrigeration equipment and central air-conditioning systems. Master certain theoretical knowledge of refrigeration and air-conditioning, and the training targets are senior workers, technicians and senior technicians. Background technique: [0002] Refrigeration and air-conditioning are widely used in industry, commerce and daily life. The society urgently needs first-line technicians with experience in maintenance and management of refrigeration and air-conditioning systems. Labor and personnel management agencies have clear regulations on training and assessment of refrigeration and air-condition...
