[0015] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0016] During the towing test of the wind turbine on the test bench, the failure of the main bearing, gearbox, generator, converter and other structures will cause great damage to the test bench. Therefore, it is necessary to monitor the test data of the wind turbine.

[0017] Since the power supply system, traction-end main control system, test-end main control system and data acquisition system used to test wind turbines on the test bench are relatively independent, currently a separate device is configured for each system to monitor the data of the corresponding system, which is costly. In addition, when users need to view or analyze data from different systems, they need to frequently switch between different devices, and the process is also cumbersome.

[0018] To this end, an embodiment of the present application provides a test bench status monitoring system and a test platform, which can not only reduce the data monitoring cost, but also reduce the operations of users when viewing or analyzing data from different systems.

[0019] The status monitoring system provided in the embodiment of the present application establishes communication between the lower computer and the upper computer and the main control system, data acquisition equipment and power supply system on the wind turbine test bench, so that the lower computer can obtain the full test data of the wind turbine and display it through the upper computer. That is, the embodiment of the present application can simultaneously monitor the full test data of the wind turbine through one device, and there is no need to configure one device for each system on the wind turbine test bench, thereby reducing costs.

[0020] The state monitoring system provided by the embodiment of the present application is not limited to a specific model of wind turbines and specific working conditions, that is, the test data of any model of wind turbines under any working conditions can be monitored. When the model and working conditions of the unit are different, only the communication protocol and protection logic need to be modified accordingly, which has strong versatility.

[0021] The following describes in detail the state monitoring system and test platform of the test bench provided in the embodiment of the present application through specific embodiments.

[0022] Figure 1 A structural diagram of a state monitoring system of a test bench provided in an embodiment of the present application, such as Figure 1As shown, the state monitoring system 10 of the test bench may include a host computer 101 and a slave computer 102. The host computer 101 may be an electronic device with display and storage functions, such as a laptop computer, a desktop computer, etc. Accordingly, the host computer 101 may include a display 1010. The display 1010 may display the data of the main control system, the data acquisition device, and the power supply system received by the host computer 101 in a preset display form. The preset display form may include, for example, a chart form, a waveform form, a curve form, etc.

[0023] The lower computer 102 may be a device with programmable functions, such as a programmable logic controller (PLC) or other devices with programmable functions. The lower computer 102 may include at least two data transmission ports, and the lower computer 102 may communicate with different devices through different data transmission ports to achieve different functions.

[0024] Taking the lower computer 102 including two data transmission ports as an example, illustratively, the first data transmission port 1021 of the lower computer 102 can be connected to the upper computer 101, and through the first data transmission port 1021, the lower computer 102 can transmit the acquired data of the main control system, data acquisition equipment, and power supply system of the wind turbine test bench to the upper computer 101. At the same time, through the first data transmission port 1021, the lower computer 102 can also receive the program issued by the upper computer 101, which is used to realize the functions of performing logical operations and fault warning on the acquired data of the main control system, data acquisition equipment, and power supply system.

[0025] For example, the second data transmission port 1022 of the lower computer 102 can be connected to the data transmission port of the main control system on the wind turbine test bench, the data transmission port of the data acquisition device, and the data transmission port of the power supply system, respectively, so that the lower computer 102 can communicate with the main control system, the data acquisition device, and the power supply system to achieve data transmission. For example, the lower computer 102 can obtain data from the main control system, the data acquisition device, and the power supply system. It can also send a shutdown command to the main control system, the data acquisition device, and the power supply system at the same time.

[0026] The protocol types supported by the first data transmission port 1021 and the second data transmission port 1022 may be the same or different.

[0027] Exemplarily, the first data transmission port 1021 can communicate with the host computer 101 through any of the following communication protocols: industrial control data exchange Modbus communication protocol, Automation Device Specification (ADS) communication protocol, Controller Area Network (CAN) communication protocol, Fieldbus (Decentralized Periphery, DP) communication protocol. Among them, the Modbus communication protocol can include Modbus TCP and Modbus RTU.

[0028] Exemplarily, the second data transmission port 1022 can communicate with the main control system, the data acquisition device, and the power supply system through at least one of the following communication protocols: Modbus communication protocol, ADS communication protocol, CAN communication protocol, DP communication protocol. That is, the communication protocols of the lower computer 102 and the main control system, the data acquisition device, and the power supply system can be the same or different.

[0029] The embodiment of the present application establishes communication between the lower computer and the upper computer and various systems of the test bench based on the corresponding communication protocol, so that the lower computer can obtain the full test data of the wind turbine set and display it through the upper computer, thereby realizing all-round monitoring of the test bench and providing guarantee for the safe and stable operation of the test bench.

[0030] After the test is completed, the user can export all data through the host computer 101 to facilitate subsequent review and analysis.

[0031] In some embodiments, Figure 2 As shown, the state monitoring system 10 may further include: a driving device 103 and an early warning device 104;

[0032] The input end of the driving device 103 is connected to the output end of the lower computer 102, and the output end of the driving device 103 is connected to the input end of the early warning device 104;

[0033] The driving device 103 receives the driving signal sent by the lower computer 102 , and sends an early warning signal to the early warning device 104 .

[0034] Exemplarily, the driving device 103 may be a signal generator, that is, a device that can output a level signal. When the lower computer 102 detects abnormal test data, it may send a driving signal to the driving device 103. The abnormal test data may be abnormal power supply data of the power supply system, operating data of the wind turbine, etc.

[0035] The warning device 104 may be, for example, a speaker, an indicator light, an audible and visual alarm, etc., and may warn in one manner or in different manners at the same time.

[0036] The warning signal may be a high-level signal. The warning device 104 may implement a warning function based on the received warning signal to reduce the loss to the test bench.

[0037] Exemplarily, while sending a driving signal to the driving device 103, the lower computer 102 may also send a shutdown command to the main control system, the data acquisition device and the power supply system to protect the main control system, the data acquisition device and the power supply system.

[0038] The embodiment of the present application communicates with the lower computer and the early warning device through the driving device, so that the driving device can send an early warning signal to the early warning device based on the driving signal sent by the lower computer, thereby realizing the early warning function, effectively protecting the test bench, and reducing the testing cost of the wind turbine set.

[0039] In some embodiments, Figure 2 As shown, the host computer 101 may further include a memory 1011. In the embodiment of the present application, the memory 1011 and the display 1010 are integrated into the same host computer 101, which can effectively reduce the cost of status monitoring.

[0040] Exemplarily, the memory 1011 can store the data of the main control system, data acquisition equipment and power supply system received by the host computer according to the same time dimension. The data here can be the full amount of data of the wind turbine test. Considering that the main control system, data acquisition equipment and power supply system on the test bench are relatively independent, that is, the timestamps of the data collected by each system may be inconsistent. In order to facilitate subsequent summary and review, the memory 1011 can store the data of each system according to the same time dimension. For example, the timestamp of one of the systems can be used as a benchmark, or the local time can be used as a benchmark.

[0041] The embodiment of the present application can store the full amount of data of the wind turbine acquired by the lower computer in the memory of the upper computer according to the same time dimension, which is convenient for subsequent test summary and review.

[0042] In some embodiments, Figure 2 As shown, the state monitoring system 10 may further include: a power supply 105 , which is connected to the lower computer 102 for power supply, so that the lower computer 102 can work normally.

[0043] Exemplarily, the power supply 105 may be a power supply with a fixed supply voltage, such as a 24V switching power supply. Exemplarily, the power supply 105 may also be a power supply with an adjustable voltage, such as a controllable power supply, and the voltage may be adjustable between 24V and 100V. In actual application, a suitable power supply may be selected to power the lower computer 102 according to the test requirements.

[0044] In some embodiments, Figure 2 As shown, the status monitoring system 10 may further include: a switch 106, the switch 106 includes a first port 1061 and a second port 1062;

[0045] The first port 1061 is connected to the second data transmission port 1022 of the lower computer 102, and the second port 1062 is connected to the data transmission port of the main control system, the data transmission port of the data acquisition device, and the data transmission port of the power supply system respectively.

[0046] The second port 1062 may include multiple second ports 1062. When there are multiple second ports 1062, the data transmission port of the main control system, the data transmission port of the data acquisition device, and the data transmission port of the power supply system can be connected to the same second port 1062 or to different second ports 1062.

[0047] The embodiment of the present application realizes communication between the lower computer and various systems of the test bench through a switch, eliminates the independent barriers between different systems, and reduces the cost of data transmission.

[0048] Based on the same concept, the present application embodiment also provides a test platform, such as Figure 3-Figure 4 As shown, the experimental platform 30 may include a wind turbine test bench 31 and the state monitoring system 10 of the test bench in the above embodiment.

[0049] The wind turbine test bench 31 may include a power supply system 310 , a main control system 320 , a data acquisition device 330 , a driving component 340 , a test component 350 and a sensor 360 . Figure 4 The display 1010 and the memory 1011 of the host computer 101 are described separately as an example. In actual application, the display 1010 and the memory 1011 can be integrated into the same device.

[0050] The power supply system 310 is used to supply power to the wind turbine test bench 31 .

[0051] The main control system 320 may include a drag component main control system 3201 and a test component main control system 3202, wherein the drag component main control system 3201 and the test component main control system 3202 may both be programmable logic controllers PLCs. The drag component main control system 3201 is connected to the drag component 340, and the test component main control system 3202 is connected to the test component 350. The drag component 340 may include, for example, an electric motor, and the test component 350 may include, for example, a generator, and the electric motor drives the generator to generate electricity to simulate a wind turbine.

[0052] The sensor 360 may be provided on the drag component 340 and the test component 350, and may include, for example, a temperature sensor, a pressure sensor, a wind speed sensor, a torque sensor, etc. Different numbers of sensors may be deployed on the drag component 340 and the test component 350 according to different test requirements. The data acquisition device 330 is connected to the sensor 360 to collect measurement data of the sensor 360.

[0053] Part of the data collected by the sensor 360 can be uploaded to the drag component main control system 3201 and the tested component main control system 3202, and the rest can be uploaded to the data acquisition device 330. Of course, in addition to obtaining data from the sensor 360, the drag component main control system 3201 and the tested component main control system 3202 can also obtain data that cannot be obtained through the sensor 360. That is, the main control system 320 and the data acquisition device 330 can obtain the full amount of test data of the wind turbine.

[0054] Exemplarily, the power supply system 310 and the data acquisition device can communicate with the lower computer 102 in the state monitoring system 10 of the test bench through the Modbus TCP communication protocol, and the drag component main control system 3201 and the test component main control system 3202 can communicate with the lower computer 102 in the state monitoring system 10 of the test bench through the ADS communication protocol. Of course, other protocols can also be used, which are not specifically limited in the embodiments of the present application.

[0055] In addition, by establishing communication between the wind turbine test bench and the status monitoring system of the test bench, the embodiment of the present application can also realize remote opening and closing and power-on self-test functions through the status monitoring system of the test bench, effectively reducing the risk of manual opening and closing.

[0056] The test platform of the embodiment of the present application may include a wind turbine test bench for simulating the test of the wind turbine and a state monitoring system of the test bench. By establishing communication between the state monitoring system of the test bench and the wind turbine test bench, the state monitoring system of the test bench can obtain the full test data of the wind turbine test bench and monitor the full data, which can not only reduce the monitoring cost, but also effectively protect the wind turbine test bench and reduce the loss of the wind turbine test bench due to test abnormalities.
