[0018] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples. In the accompanying drawings and the following description, at least some well-known structures and techniques are not shown to avoid unnecessarily obscuring the application; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0019] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the cable-stayed tower and wind turbine generator set of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] To better understand this application, the measurement and control platform of the wind turbine generator test bench provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the measurement and control platform 10 of the wind turbine generator test bench may include a host computer 101, a measurement and control system 102, a safety chain system 103, and a wind turbine generator test bench system 104.

[0022] The output of the host computer 101 is connected to the input of the measurement and control system 102. The host computer 101 can be a device capable of communicating with the measurement and control system 102, such as a laptop, desktop computer, or industrial computer. The host computer 101 and the measurement and control system 102 are located on the same network. For example, the host computer 101 can interact with the measurement and control system 102 via the Automation Device Specification (ADS) protocol. For instance, the measurement and control system 102 can send acquired data from the experimental platform system 104 to the host computer 101 for display, and the host computer 101 can also send commands to the measurement and control system 102, which then controls the experimental platform system 104 based on the received commands. The experimental platform system 104 may include subsystems related to the wind turbine, such as a power distribution system, water cooling system, lubrication system, heat dissipation system, multi-stress environment chamber, drive inverter system, drive transmission chain system, multi-degree-of-freedom loading system, power grid simulator, and the tested unit.

[0023] For example, the measurement and control system 102 can send circuit breaker opening and closing commands to the power distribution system, cooling water flow commands to the water cooling system, high and low speed lubrication commands to the lubrication system, fan opening commands to the heat dissipation system, temperature and humidity commands to the multi-stress environment chamber, speed commands to the drive frequency converter system, load commands to the multi-degree-of-freedom loading system, and power commands to the tested unit.

[0024] In some embodiments, the output terminal of the host computer 101 can be used solely as an output terminal, or it can be used as both an output terminal and an input terminal. That is, the host computer 101 can send commands to the measurement and control system 102 through this port, and it can also receive data sent by the measurement and control system 102 through this port. Similarly, the input terminal of the measurement and control system 102 can be used solely as an input terminal, or it can be used as both an input terminal and an output terminal. That is, the measurement and control system 102 can send data to the host computer 101 through this port, and it can also receive commands sent by 101 through this port.

[0025] The measurement and control system 102 is mainly used to send control commands to various subsystems on the experimental platform system 104 based on the instructions issued by the host computer 101. It can also collect data from various subsystems on the experimental platform system 104 and send it to the host computer 101 for display. For example, the measurement and control system 102 may include a programmable logic controller (PLC).

[0026] For example, the measurement and control system 102 can be composed of a single device or multiple devices. For instance, in some embodiments, the measurement and control system 102 may include a master station and slave stations. There may be one or more slave stations, depending on the actual needs of the experimental platform. There may be one master station. The master station and slave stations communicate with each other. The master station communicates with the host computer 101, and the slave stations communicate with the experimental platform system 104.

[0027] The safety chain system 103 is mainly used to protect the experimental platform system 104, providing a guarantee for the safe and stable operation of the experimental platform. For example, the output of the safety chain system 103 is connected to the input of the measurement and control system 102 via a first switch 105, and the output of the safety chain system 103 is also connected to the input of the experimental platform system 104. The input of the safety chain system 103 is connected to the output of the measurement and control system 102 via a second switch 106.

[0028] The first switch 105 may be a normally closed switch, including a relay and a coil. For example, when the safety chain system 103 is not in operation and / or at least one subsystem on the test bench system 104 is in an abnormal state, the first switch 105 is open, and when the safety chain system 103 is in operation and all subsystems on the test bench system 104 are in normal state, the first switch 105 is closed.

[0029] For example, the measurement and control system 102 can detect the state of the first switch 105 in real time. When the first switch 105 is open, the measurement and control system 102 can send an emergency stop signal to the experimental platform system 104 to stop the operation of the experimental platform system 104.

[0030] For example, when the experimental platform system 104 has not yet started and the first switch 105 is open, the measurement and control system 102 can send a start-prohibition signal to the experimental platform system 104. At the same time, the "start" button of the experimental platform system 104 displayed on the display interface of the host computer 101 is in an invalid state, for example, it can be displayed gray. At this time, the user cannot operate the "start" button of the experimental platform system 104 displayed on the display interface. Thus, the experimental platform system 104 can be protected.

[0031] For example, the second switch 106 can also be a normally closed switch, which can be composed of a relay and a coil. For example, the second switch 106 opens when the measurement and control system 102 is in an abnormal state. Another example is that the second switch 106 opens when the data of at least one subsystem of the experimental platform system 104 is in an abnormal state. Yet another example is that the second switch 106 opens when both the measurement and control system 102 and the data of at least one subsystem of the experimental platform system 104 are in an abnormal state. When the safety chain system 103 detects that the second switch 106 has opened, it sends an emergency stop signal to the experimental platform system 104, causing the experimental platform system 104 to stop operating.

[0032] For example, there may be two second switches 106, such as one second switch 106 for responding to state changes in the measurement and control system 102, and another second switch 106 for responding to changes in the experimental platform system 104. If the safety chain system 103 detects that either second switch 106 is open, it will send an emergency stop signal to the experimental platform system 104.

[0033] Therefore, when the measurement and control system 102 malfunctions or the data of the experimental platform system malfunctions, the experimental platform can be protected by the safety chain system 103. When the safety chain system 103 is not in operation or the experimental platform system 104 malfunctions, the experimental platform can be protected by the measurement and control system 102. This achieves dual protection for the experimental platform, improves its safety protection capability, and provides a guarantee for the stable operation of the experimental platform.

[0034] For example, when the data of the experimental platform system 104 is abnormal, the safety chain system 103 sends an emergency stop signal to the experimental platform system 104 based on the state of the second switch 106. The measurement and control system 102 can also send an emergency stop signal to the experimental platform system 104. This can prevent the emergency stop signal transmission from being delayed due to transmission link interference or other reasons, thereby damaging the experimental platform and achieving dual protection for the experimental platform.

[0035] In some embodiments, such as Figure 2 As shown, the measurement and control system 102 may include a measurement and control system master station 1021 and at least one first measurement and control system slave station 1022. Figure 2 Taking a system comprising three first control system slave stations 1022 as an example, in practical applications, the first control system slave stations 1022 may include one, two, or more. The number of first control system slave stations 1022 may be related to the location of the subsystems on the experimental platform system 104. For example, if the locations of the subsystems on the experimental platform system 104 are relatively concentrated, the number of first control system slave stations 1022 may be relatively small; for example, only one first control system slave station 1022 may be set up. If the locations of the subsystems on the experimental platform system 104 are relatively dispersed and far apart, multiple first control system slave stations 1022 may be set up. For example, for subsystems with relatively concentrated locations, one first control system slave station 1022 may be set up.

[0036] The input terminal of the first control system slave station 1022 can also be used as an output terminal. Similarly, the output terminal of the control system master station 1021, which is connected to the input terminal of the first control system slave station 1022, can also be used as an input terminal. The input terminal of each first control system slave station 1022 can be directly connected to the output terminal of the control system master station 1021. This method of directly connecting the first control system slave stations 1022 to each other is suitable for situations where the distance between each first control system slave station 1022 and the control system master station 1021 is relatively short.

[0037] The output of each first measurement and control system slave station 1022 is connected to the input of at least one subsystem on the experimental platform system 104. Different first measurement and control system slave stations 1022 can be connected to different subsystems. Thus, the measurement and control system master station 1021 can synchronously control multiple subsystems of the experimental platform system 104 through multiple first measurement and control system slave stations 1022.

[0038] In some embodiments, the measurement and control platform 10 of the wind turbine generator test bench may further include a switch 107, which is used when the distance between each first measurement and control system slave station 1022 and the measurement and control system master station 1021 is relatively far. Figure 3 As shown, each slave station 1022 of the first measurement and control system can be connected to the master station 1021 of the measurement and control system through the switch 107.

[0039] For example, the first measurement and control system slave station 1022 and the measurement and control system master station 1021 can communicate via the EtherCAT protocol, or via other protocols with cascading expansion capabilities and suitable for experimental use. Accordingly, the switch 107 can be an EtherCAT switch that supports the EtherCAT protocol.

[0040] In this embodiment, the master station of the measurement and control system is connected to at least one slave station of the first measurement and control system, and each slave station of the first measurement and control system is connected to at least one subsystem on the experimental platform system. Thus, the master station of the measurement and control system can synchronously control multiple subsystems on the experimental platform system, thereby improving the test results.

[0041] In practical applications, corresponding subsystems can be added to the experimental platform system 104 according to testing requirements. When the location of the newly added subsystem is far from that of other subsystems, a corresponding measurement and control system slave station needs to be added to communicate with the newly added subsystem. Based on this, in some embodiments, such as Figure 4 As shown, the measurement and control system 102 may also include at least one second measurement and control system slave station 1023. Figure 4 Taking two second control system slave stations 1023 as an example, in actual applications, there may be more second control system slave stations 1023.

[0042] The input terminal of each second measurement and control system slave station 1023 is connected to the output terminal of the measurement and control system master station 1021, and the output terminal of each second measurement and control system slave station 1023 is connected to the input terminal of at least one subsystem on the experimental platform system 104.

[0043] Figure 4 Taking the expansion of the telemetry and control system master station 1021 into a second telemetry and control system slave station 1023 as an example, or it can also be done in... Figure 3 Based on this, multiple second measurement and control system slave stations 1023 are extended from switch 107.

[0044] In some embodiments, it can also be extended from the slave station of the measurement and control system. For example... Figure 5 As shown, the telemetry and control system 102 may also include at least one third telemetry and control system slave station 1024; Figure 5 Taking two third-level telemetry and control system slave stations 1024 as an example, in actual applications, more third-level telemetry and control system slave stations 1024 can be included.

[0045] Among them, each of the third measurement and control system slave stations 1024 is connected in sequence, and the input terminal of the first third measurement and control system slave station 1024 after being connected in sequence is connected to the output terminal of the target measurement and control system slave station. The target measurement and control system slave station is any one of the measurement and control system slave stations connected to the output terminal of the measurement and control system master station 1021. The output terminal of each third measurement and control system slave station 1024 is connected to the input terminal of at least one subsystem on the experimental platform system 104.

[0046] The target measurement and control system slave station can be, for example, Figure 4 Any of the first telemetry and control system slave stations 1022 in the system can also be Figure 4Any of the second measurement and control system slave stations 1023 in the system may include both the first measurement and control system slave station 1022 and the second measurement and control system slave station 1023. Figure 5 Taking the expansion of the third telemetry and control system slave station 1024 from the first telemetry and control system slave station 1022 as an example. Figure 5 As shown, two third control system slave stations 1024 are connected in series and then connected to the first control system slave station 1022. Each third control system slave station 1024 is also connected to at least one subsystem on the experimental platform system 104. Thus, the control system master station 1021 can synchronously control each subsystem on the experimental platform system 104.

[0047] Both the slave station and the master station of the measurement and control system in this embodiment have expansion capabilities. When adding new equipment to the experimental platform, the slave station of the measurement and control system can be expanded on the master station or the switch of the measurement and control system, or it can be expanded from a slave station of the measurement and control system to integrate the newly added equipment on the experimental platform with other equipment, which improves the flexibility of the expansion method, eliminates the need to rebuild the experimental platform, and greatly reduces costs.

[0048] Each control and measurement system slave station has a similar structure. Taking the slave station of the first control and measurement system as an example, such as... Figure 6 As shown, the first control system slave station 1022 may include a first slave coupler 10221, a data communication card 10222, and a data acquisition card 10223.

[0049] The first slave coupler 10221, data communication card 10222, and data acquisition card 10223 are connected in sequence. The first slave coupler 10221 is used for cascaded communication with the preceding stage device, for example, in... Figure 2 In this configuration, the input terminal of the first slave coupler 10221 is connected to the output terminal of the master station 1021 of the telemetry and control system, for communication with the master station 1021. For example, in... Figure 5 In this system, the slave coupler in the third control system slave station 1023 is connected to the slave coupler of the previous control system slave station. For example, the slave coupler of the first third control system slave station 1023, which is connected to the first control system slave station 1022, is connected to the slave coupler of the first control system slave station 1022, and is also connected to the slave coupler of the second third control system slave station 1023. Thus, it can communicate with the first control system slave station 1022 and the third control system slave station 1023 respectively.

[0050] The input terminal of the data communication card 10222 is also connected to the output terminal of the first subsystem 1041 on the experimental platform system 104, and the output terminal of the data communication card 10222 is connected to the input terminal of the data acquisition card 10223, for receiving the first data acquired by the first subsystem 1041. The first subsystem 1041 can be a system with data acquisition capabilities, that is, the first subsystem 1041 can acquire its own data and send the acquired data to the data communication card 10222. The data communication card 10222 can support protocols such as RS232, Controller Area Network (CAN), DP (Decentralized Periphery), Modbus TCP, and Modbus RTU. For example, the data communication card 10222 can convert data into EtherCAT format for transmission in the measurement and control system 102.

[0051] The input terminal of the data acquisition card 10223 is also connected to the output terminal of the second subsystem 1042 on the experimental platform system 104. The second subsystem 1042 is a subsystem without data acquisition capabilities; that is, data from the second subsystem 1042, such as temperature and pressure, needs to be acquired by the data acquisition card 10223. The data acquisition card 10223 can include analog and digital signals and can perform analog-to-digital conversion. The data acquisition card 10223 can also convert the acquired data into EtherCAT format for transmission in the measurement and control system 102.

[0052] In some embodiments, the measurement and control system slave station may also include one of the data acquisition card 10223 and the data communication card 10222, depending on the subsystems connected to the experimental platform. For example, if all the subsystems connected to the experimental platform have data acquisition functions, the measurement and control system slave station may only include a slave coupler and the data communication card 10222. If none of the subsystems connected to the experimental platform have data acquisition functions, the measurement and control system slave station may only include a slave coupler and the data acquisition card 10223.

[0053] The master station 1021 of the measurement and control system integrates all subsystems on the experimental platform through the data communication card 10222 and data acquisition card 10223 in the slave station of the measurement and control system, thereby realizing data monitoring and control of all subsystems.

[0054] The slave stations of the measurement and control system in this embodiment have a similar structure. They can communicate with the preceding equipment through their respective slave couplers, and can also communicate with the experimental platform system to obtain data from the experimental platform system. Finally, the data is transmitted to the measurement and control system, which sends it to the host computer for display. At the same time, the measurement and control system can also monitor the abnormalities of the experimental platform system in real time, providing a basis for protecting the experimental platform.

[0055] In some embodiments, such as Figure 7 As shown, the security chain system 103 may include a security chain master station 1031 and at least one first security chain slave station 1032. Figure 7 Taking two first security chain slave stations 1032 as an example, in practical applications, the first security chain slave station 1032 may also include one or more. The number of first security chain slave stations 1032 may be related to the number of subsystems on the experimental platform system 104. For example, if the experimental platform system 104 includes three subsystems, then there may be three first security chain slave stations 1032, with the output of each first security chain slave station 1032 connected to the input of one subsystem on the experimental platform system 104.

[0056] The input terminal of the safety chain master station 1031 is connected to the output terminal of the measurement and control system 102 through the second switch 106, and the output terminal of the safety chain master station 1031 is connected to the input terminal of each first safety chain slave station 1032.

[0057] For example, the security chain master station 1031 can communicate with each first security chain slave station 1032 via the FSoE (Frame Switching over Ethernet) protocol.

[0058] Each security chain slave station has a similar structure. For example, the first security chain slave station 1032 may include a slave coupler and a security module. The slave coupler is used for cascading communication with the preceding stage device, for example in... Figure 7 In this system, the slave coupler of each first security chain slave station 1032 communicates with the security chain master station 1031. The security module is mainly used to send an emergency stop signal to the experimental platform system 104 to stop the experimental platform system 104 from operating.

[0059] In some embodiments, when the distance between each first security chain slave station 1032 is far, each first security chain slave station can also communicate with the security chain master station 1031 through a switch.

[0060] For example, when the second switch 106 is disconnected, the safety chain master station 1031 can send an emergency stop signal to the experimental platform system 104 through the first safety chain slave station 1032, preventing damage to the experimental platform due to malfunctions in the measurement and control system 102 or data anomalies in the experimental platform system 104, thus effectively protecting the experimental platform. Furthermore, since each first safety chain slave station communicates with the safety chain master station, the safety chain master station can simultaneously send emergency stop signals to each first safety chain slave station, thereby synchronously controlling the shutdown of each subsystem.

[0061] Similar to the measurement and control system 102, the safety chain system 103 in this embodiment also supports extended functions. In some embodiments, such as Figure 8As shown, the security chain system 103 may also include at least one second security chain slave station 1033. Figure 8 Taking two secondary security chain slaves 1033 as an example, in actual applications, there can be more secondary security chain slaves 1033.

[0062] The input of each second security chain slave station 1033 is connected to the output of the security chain master station 1031, and the output of each second security chain slave station 1033 is connected to the input of a subsystem on the experimental platform system.

[0063] Figure 8 Take the example of directly extending the second security chain slave station 1033 from the security chain master station 1031.

[0064] In some embodiments, such as Figure 9 As shown, the security chain system 103 may also include at least one third security chain slave station 1034. Figure 9 Taking two third security chain slave stations 1034 as an example, in actual applications, there can be more third security chain slave stations 1034.

[0065] Figure 9 Taking the expansion of the security chain slave stations based on the existing security chain slave stations as an example. In this embodiment, each third security chain slave station 1034 is connected sequentially, and the input terminal of the first third security chain slave station 1034 after sequential connection is connected to the output terminal of the target security chain slave station. The target security chain slave station is any one of the security chain slave stations connected to the output terminal of the security chain master station.

[0066] Figure 9 Taking the target security chain slave station and the second security chain slave station 1033 as an example, in practical applications, it can also be extended on the first security chain slave station 1032, or simultaneously extended on the first security chain slave station 1032 and the second security chain slave station 1033.

[0067] Both the security chain master station and the security chain slave station in this embodiment have expansion capabilities. When adding new devices to the experimental platform, the security chain slave station can be expanded on the security chain master station or the switch, or it can be expanded from a certain security chain slave station to integrate the newly added devices on the experimental platform with other devices, which improves the flexibility of the expansion method, eliminates the need to rebuild the experimental platform, and greatly reduces costs.

[0068] In some embodiments, the measurement and control system may further include a third switch. For example, the third switch may be a normally closed switch, and the output terminal of the first safety chain slave station is connected to the input terminal of the subsystem corresponding to the first safety chain slave station through the third switch. When the safety chain system or the measurement and control system malfunctions, the third switch is opened, and the subsystem corresponding to the first safety chain slave station stops operating.

[0069] For example, the measurement and control system may further include a fourth switch, which may be a normally closed switch. The input terminal of the first safety chain slave station is connected to the output terminal of the subsystem corresponding to the first safety chain slave station through the fourth switch. When the subsystem corresponding to the first safety chain slave station malfunctions, the fourth switch opens, and the corresponding first safety chain slave station sends an emergency stop request to the safety chain master station. At this time, the first switch opens, and the measurement and control system sends an emergency stop signal to the experimental platform system.

[0070] The experimental platform system in this embodiment can not only monitor the safety chain system, but can also be monitored by the safety chain system, thereby realizing bidirectional monitoring and protection, improving the protection capability of the experimental platform system, and providing a guarantee for the operation of the experimental platform.

[0071] Figure 10 An exemplary system architecture diagram of a measurement and control platform is provided, such as... Figure 10 As shown, the power distribution system 1043 on the experimental platform system 104 is connected to the drive inverter system 1044 and the power grid simulator 1045, respectively.
