[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] A fatigue test multi-task management system based on LAN, such as Figure 1-Figure 2 As shown, a LAN architecture design is adopted, including a host computer, a multi-network port workstation and a slave computer.

[0019] The host computer is written in the visual language LabView, and is equipped with fatigue test multi-task management software to perform management tasks such as centralized display and storage of all fatigue tests.

[0020] The lower computer includes several clients and several control systems. Each control system is independent of each other. Each client is connected to its own independent control system network through a multi-port network card to achieve two-layer network communication, solving the problem that control systems with the same URL cannot be networked.

[0021] The multi-network port workstation is used to provide a multi-system cross-platform network. The control system network is connected to the multi-system cross-platform network of the multi-network port workstation. The control system collects the working data of the corresponding client in real time and sends it to the multi-network port workstation. The multi-network port workstation then sends the data received by each control system to the fatigue test multi-task management software for management and control of the client.

[0022] For the real-time communication of complex communication networks including MTS control systems, MOOG control systems and PLC, technical application research has been conducted in both software and hardware. The hardware adopts a new networking mode, which solves the problem that there cannot be more than two MTS systems in the same local area network and realizes stable and reliable communication.

[0023] 5G network is preferred for multi-system cross-platform networks.

[0024] Preferably, the fatigue test multi-task management software includes a data receiving module, a data display module and a data processing module. The data receiving module can receive the working data collected by the control system and send it to the data processing module. Different marks are set for different control systems in the data processing module, and the received working data are classified, identified and processed, and all are sent to the data display module. The data display module includes a display interface, which can display the data received from different clients in different areas on the display interface.

[0025] At the same time, the data processing module can also perform fault alarms. The specific design is as follows: the data processing module stores the client's standard working data. After receiving the working data collected by the control system, it determines the type of working data and searches for the corresponding client's standard working data for comparison, and determines whether the difference between the two is within the set threshold range. If so, it is determined that the client is working normally. Otherwise, it is determined that the client has a fault and sound and light alarms are sounded. Thus, the client's fault can be handled in a timely manner.

[0026] The thresholds corresponding to different working data are set according to experience.

[0027] Preferably, different sub-panels are provided on the display interface corresponding to different tests, and each sub-panel is marked with the name and parameters of the corresponding test. The parameters include the oil pump used, the control system type, the file address to be read, the current task and other parameters. The names and parameters are defined by the Excel file.

[0028] When a new test is replaced in any client, the corresponding test name and parameters are modified through Excel on the corresponding sub-panel and transmitted to the display interface. The display interface will be modified synchronously to achieve flexible dynamic switching.

[0029] Preferably, a storage module is provided in the fatigue test multi-task management software, which can simultaneously receive the working data sent by the data receiving module and store the data of different clients in order by category and time, so as to facilitate subsequent viewing.

[0030] The above design solves the problem that the on-duty personnel cannot centrally monitor the tests in the entire plant. Reasonable communication methods are adopted for different systems. Through the local area network connection, the upper computer software is used to project the screens to the large screen in the computer room and the duty room in the plant respectively. Through sound and light alarms, abnormal tests are quickly handled and the test progress is recorded, which facilitates the unified management and progress statistics of fatigue tests.

[0031] Finally, it should be noted that: the drawings of the embodiments disclosed in the present invention only involve structures related to the embodiments disclosed in the present invention, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

[0032] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
