Embodiment 1

[0028] Embodiment one: see figure 2 , 3 Shown, a kind of excavator remote diagnosis fault method, it comprises the following steps:

[0029] (1) Initialize the configuration of relevant parameters for the OPC module and the TCP-COM conversion module, including: port number, IP address, baud rate, parity bit and other related information;

[0030] (2) Establish a connection between the TCP-COM conversion module and the excavator to be tested through the GPRS wireless network and the Internet network;

[0031] (3) The inspection computer sends an access request to the connected excavator through the OPC module;

[0032] (4) The excavator to be tested (system under test) outputs each corresponding diagnostic parameter according to the access request;

[0033] (5) The inspection computer judges the acquired diagnostic parameters according to the built-in inspection program, outputs the inspection results, displays them on the inspection computer interface, and generates a repo...

Abstract

The invention discloses a remote fault diagnosis method for a digging machine, comprising the following steps: (1) carrying out relevant parameter initialization configuration on an OPC module and a TCP-COM conversion module; (2) connecting the TCP-COM conversion module and a digging machine to be detected through a GPRS wireless network and an Internet network; (3) sending an access request to the digging machine with built connection by a checking computer; (4) according to the access request, outputting corresponding diagnosis parameters by the digging machine to be detected; and (5) judging the acquired diagnosis parameters according to built-in checking program by the checking computer, and outputting the checking result. In the invention, the TCP-COM conversion module is connected to enable checking program connected with the OPC module to remotely access the designated digging machine, thus realizing remote fault diagnosis on the digging machine, improving maintenance efficiency and reducing maintenance cost.

Description

technical field [0001] The invention relates to a fault diagnosis method for an excavator, in particular to a remote fault diagnosis method for an excavator. Background technique [0002] Since the 1990s, with the continuous development of science and technology, people's production behavior and lifestyle have undergone great changes. As a very important technology in life and production, the importance of monitoring technology is gradually being recognized. recognized and accepted by people. However, most of the distributed monitoring systems currently in operation are only on the local area network, and the usual monitoring is limited to the same location, so it has certain geographical limitations. The Internet can realize resource sharing, and GPRS can realize remote wireless communication, so that people have the ability to solve problems that were difficult to solve under limited resources in the past, and provide favorable conditions for the development of remote mon...
