[0014] 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.

[0015] A box-type control device for fatigue test state monitoring, the device adopts a software and hardware combined structure design, such as Figure 1 As shown, it includes a host computer software monitoring system, a programmable logic controller and a control box. The control box is a hardware structure, and the host computer software monitoring system and the programmable logic controller are software structures. The host computer software monitoring system can remotely monitor the status of the control system in real time, and intuitively display it on the computer interface, and can save the status information in real time; the programmable logic controller can collect digital and analog data in the control box, and convert it into corresponding digital and analog data for output, completing the control of field sensors and servo valves. The control box is controlled by PLC.

[0016] Preferably, the upper computer software monitoring system includes a data transceiver module, a data processing module and a data display module. The data transceiver module can receive digital and analog data collected by the programmable logic controller and send them to the data processing module; the data processing module stores different types of data information in the data display module, and can classify different data types, and then perform data matching, and send the successfully matched data to the display unit corresponding to the data display module, and send it to the data display module, and the data display module can send the corresponding data to the connected display screen for display according to the type of information received.

[0017] Preferably, the specific method for data matching is: mark different types of data information in the data display module, after receiving the data sent by the data transceiver module, split the data and judge the data type separately, after obtaining the required data type, mark it corresponding to the stored data information, and then match the same mark until the match is successful.

[0018] Preferably, different data information of the same type may present different display states, such as low voltage / high voltage, open / closed, etc. Based on this problem, a data control group corresponding to different types of data is stored in the data processing module. After obtaining the data of the corresponding type, the data of this type is compared through the data control group to determine its data state. After the determination is completed, the corresponding determination information is sent to the data display module for display.

[0019] Preferably, a display screen connected to the data display module is provided with several command input buttons, such as low pressure / high pressure state control, and a command receiving submodule connected to the display screen is provided in the data display module. After the user presses the corresponding command input button, the corresponding sensing element sends the sensing data to the command receiving submodule, and the command receiving submodule converts the sensing data into specific command information and sends it to the data transceiver module. The data transceiver module sends the command information to the programmable logic controller to control the on-site sensors and servo valves.

[0020] Preferably, in order to be able to further control the components of the terminal, a control system and a touch screen are provided in the programmable logic controller, and 16 digital input modules are provided on the touch screen. After the programmable logic controller receives the corresponding instruction information, a total of 16 digital inputs from I0.0 to I1.7 are displayed at the corresponding positions, and the corresponding terminals of the hardware will be set to send defined instructions to the control system; the instructions output by the control system are connected to the input terminals of the control box through the DO of the control system, and the status will be displayed accordingly on the touch screen.

[0021] In a specific example, when the low voltage button is pressed on the display screen, it is sent to the PLC program of the control box through the network and the switch. After the PLC detects the signal input, it sets the corresponding input terminal. The control system detects the low voltage definition terminal through the connected DI input and performs the corresponding low voltage loading operation. When the low voltage loading is completed, the corresponding status will be output to the control box. The control box then sets the corresponding address bit. After the host computer detects it, the "low voltage" status display bit will display green, completing the entire remote control low voltage operation. Other instructions are similar to the above process.

[0022] like Figure 2 In order to facilitate mobility, the control box is designed in the shape of a trolley case, and the panel is equipped with power interface, network interface, USB interface, input and output terminals, operable screen, etc. The bottom is designed with a guide rail to install PLC and power conversion module, switch, 24V power supply, etc.

The control system or other on-site equipment can be conveniently connected through terminals to quickly build a monitoring platform and realize remote monitoring or control functions, thereby improving the response speed, shortening the test preparation cycle, and laying a hardware foundation for the establishment of a digital and intelligent strength test system. At the same time, it is easy to move and connect, with low investment cost, can be copied in large quantities, and adopts the Internet of Things development method, which is convenient for debugging and uploading test data.
