Problems solved by technology

[0003] 1. The display capacity is limited, the screen size is limited, and the content that can be displayed is limited
Therefore, it is difficult for relevant personnel to fully and intuitively understand the current working status of the electro-hydraulic system of the equipment, and there are not many help or prompts when troubleshooting
[0004] 2. After the display is damaged, it will take time to mail a new display. During this period, the equipment cannot work normally. If the equipment is in a dangerous position, the problem will be more serious.

Embodiment Construction

[0014] The present invention is realized by computer, Covey Provisit software, and German Sitai USB-CANmodul1 module. The implementation mode of the present invention is introduced in detail below, totally 3 steps:

[0015] 1: Install the driver program of the German Sytech USB-CANmodul1 module on the computer.

[0016] 2: Write and register the OCX control. The writing of the control is briefly introduced as follows:

[0017] First, create a new ActiveX project scp_can in Microsoft's VC, add a new class UcanIntf, this class adds the Initialize function to initialize, so that the USB to CAN module has the ability to receive and send data; this class increases the function of sending and receiving bus data; in this class After the class receives the data on the CAN bus, it sends the message "USBCAN_EVENT_RECIEVE" to the parent class.

[0018] Secondly, add two arrays, one array is used to register the bus ID, and the other array is used to analyze the specific content of all ...

Abstract

The invention discloses a method for monitoring the working state of an electro-hydraulic system of an engineering machine, belonging to the field of data acquisition and display of the electro-hydraulic system of the engineering machine. The system comprises a computer, a USB (Universal Serial Bus) to CAN (Controller Area Network) conversion module, an OCX control for providing a data access interface and a configuration screen compiled by using Provisit configuration software. By using the method provided by the invention, corresponding electrically controlled signals can be read from a CAN bus and vividly displayed on the configuration screen according to a way of a hydraulic schematic diagram. The method is mainly used for comprehensively monitoring the working state of the electro-hydraulic system of an engineering machine and the like and can be used for vividly displaying the working states of elements such as a pump, a valve, an oil cylinder, a pressure switch and the like in a hydraulic system so as to provide help for technicians to rapidly know about the working state of the electro-hydraulic system of the engineering machine and remove faults.

Description

technical field [0001] The invention belongs to the field of data collection and display of electro-hydraulic systems of construction machinery, and specifically uses a computer, configuration software and a data transceiver module to collect or send data in the electric control system of construction machinery and display them in real time on a configuration screen. Background technique [0002] At present, many construction machinery electronic control systems use monitors to display some simple working parameters such as engine speed, oil quantity, and working conditions. This type of display is generally composed of a single-chip microcomputer, which has the following two shortcomings: [0003] 1. The capacity of the display is limited, the size of the screen is limited, and the content that can be displayed is limited. Therefore, it is difficult for relevant personnel to fully and intuitively understand the current working status of the electro-hydraulic system of the ...
