Abstract

The invention belongs to the technical field of engine test equipment, and relates to a fault on-line monitoring system of a frequency conversion cabinet. Comprising a frequency conversion cabinet, a GCAN204, a programmable controller PLC, a touch screen and a cloud gateway. The CANH interface and the CANL interface of the CAN bus of the frequency conversion cabinet are physically connected with the CANH interface and the CANL interface of the CAN bus of the GCAN204 through two wires; an RS485 communication interface AB of the programmable logic controller PLC is connected with an ES485 communication interface AB of the GCAN204; the PLC is in MODBUSTCP communication with a touch screen and a cloud gateway at the same time, the cloud gateway sends data to a cloud platform through an MQTT protocol, and the data are sent to a mobile phone end or a webpage end on the cloud platform; data of the frequency conversion cabinet are directly read, alarm information is obtained and displayed on the touch screen, meanwhile, processing schemes and steps can be displayed on the touch screen, and maintenance schemes are sent to maintenance personnel in the form of two-dimensional codes through the cloud platform to obtain the maintenance schemes.

Description

technical field [0001] The invention belongs to the technical field of engine test equipment, and relates to an online fault monitoring system of a frequency conversion cabinet. Background technique [0002] Failure of the bench cannot be detected in time, which seriously affects the mobility of the bench. It is necessary to design a fault online monitoring system to monitor and predict the test status and fault conditions of the bench to ensure the normal operation of the bench. Otherwise, when the equipment fails , it is impossible to determine what the fault is, and there is no solution. There is no relevant patent or document at present. [0003] The patent document with the application number 201720426218.2 discloses an online monitoring device for energy-saving frequency converters, including a monitoring host. The monitoring host includes an outer shell. The outer shell has a rectangular parallelepiped structure. A display screen is fixed on the front surface of the ...
