[0001] This application relates to the field of new energy power generation technology, and in particular to a data acquisition device for new energy power generation equipment. Background Technology

[0002] With the rapid development of new energy power generation technologies (such as wind power and photovoltaic power), the number of power generation devices in new energy power plants has also increased dramatically. Given the large number of power generation devices in new energy power plants, the management of these devices and the diagnosis and early warning of faults have become increasingly important.

[0003] Currently, renewable energy power plants typically obtain operational data from various power generation devices using sensors installed at each device. However, renewable energy power plants contain a variety of different equipment, such as inverters and fault diagnosis devices. This method of monitoring operational data by placing sensors at each power generation device can easily create data silos, preventing data sharing between devices and thus affecting the safety of the entire system. In addition, existing renewable energy power plants also use SCADA systems located at the station control center to monitor the operational data of the power generation equipment. However, due to limitations in SCADA hardware and configuration, only a limited number of operational data points can be collected, resulting in insufficient monitoring points and hindering fault diagnosis and early warning.

[0020] It should be understood that this application provides a data acquisition device for new energy power generation equipment, including: a chassis and an AC / DC converter, an analog data acquisition unit, a computer, and a switch disposed within the chassis. Since these technical solutions solve problems based on the same or similar principles, some repetitive details may not be repeated in the following description of specific embodiments. However, it should be considered that these specific embodiments have mutual references and can be combined with each other.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. In case of any inconsistency, the meaning set forth in this specification or derived from the content described herein shall prevail. Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0022] Before introducing the specific implementation method of the data acquisition device for new energy power generation equipment of this application, the application scenarios of the data acquisition device will be introduced first.

[0023] The data acquisition device for new energy power generation equipment in this application is applied to the edge of the power generation equipment in a new energy power plant. For example, the device can be deployed near or inside equipment such as wind turbines, inverters, and transformers to collect real-time operating data of these devices to assess their operating status. The new energy power plants in this embodiment include, but are not limited to, wind power plants and photovoltaic power plants.

[0024] The data acquisition device for new energy power generation equipment provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, the data acquisition device includes a chassis 100, an AC / DC converter 110 housed within the chassis 100, an analog signal acquisition unit 120, a computer 130, and a switch 140. The components of this data acquisition device will be described in detail below.

[0026] In one implementation, the chassis 100 can be an aluminum chassis; in another implementation, the chassis 100 can also be a chassis made of hard plastic, etc.

[0027] The AC terminal of the AC-DC converter 110 is connected to the mains input terminal via a first switch K1. This AC-DC converter 110 is used to convert AC mains power (AC) into DC power (DC) required by other devices, thereby powering those components.

[0028] In one specific implementation, the mains power is 220V AC, and the analog signal acquisition device 120, computer 130, and switch 140 are all devices that support 24V DC input. Therefore, in this case, the AC / DC converter 110 is used to convert the 220V AC to 24V DC to power the analog signal acquisition device 120, computer 130, and switch 140. It should be understood that 24V here is an exemplary description; in other embodiments, this voltage value can be determined according to the actual input voltage required by the devices, such as 30V, 5V, 3V, etc.

[0029] In one implementation, the AC / DC converter 110 can be a switching power supply, thereby realizing the AC / DC conversion function.

[0030] In this embodiment, the number of AC / DC converters 110 is not limited. If other devices require the same voltage (e.g., all require a 24V input voltage), then a single AC / DC converter 110 can power all other devices. Figure 1 As shown, the DC terminals of the AC / DC converters are connected to the analog signal acquisition unit 120, the computer 130, and the switch 140, respectively, to power the analog signal acquisition unit 120, the computer 130, and the switch 140. If other devices require different voltage values ​​(for example, in addition to devices requiring a 24V input voltage, there are also devices requiring a 3V input voltage), multiple AC / DC converters 110 can be used to power each device separately.

[0031] The analog data acquisition unit 120 is connected to a physical sensor located on the side of the new energy power generation equipment, thereby obtaining analog quantities of real-time operating data of the power generation equipment collected by the physical sensor, and converting the obtained analog quantities of real-time operating data into digital quantities of real-time operating data. It should be understood that the physical sensor in this embodiment may include, for example, a temperature sensor, a vibration sensor, a pressure sensor, etc.

[0032] In one implementation, the analog signal acquisition unit 120 can be an analog signal acquisition unit that supports 32 analog inputs. However, this embodiment does not limit the number of analog signal acquisition units 120. As an example, the number of analog signal acquisition units 120 can be two.

[0033] Computer 130 is connected to analog signal acquisition unit 120 via Ethernet and is used to store digital signals transmitted from analog signal acquisition unit 120. As one implementation, the data transmission channel between computer 130 and analog signal acquisition unit 120 can be Ethernet, and the data transmission protocol between computer 130 and analog signal acquisition unit 120 can be MODBUS-TCP.

[0034] In some embodiments, the computer 130 is also used to analyze the acquired digital signals, perform AI autonomous learning, and conduct edge computing.

[0035] In some embodiments, the computer 130 also includes a display device, such as a display screen or a touch screen. The display device can display the digital signals obtained by the computer 130 from the analog signal acquisition unit 120, and can also display the data after analysis, AI autonomous learning and edge computing, for maintenance personnel to view or analyze faults.

[0036] Switch 140 is connected to computer 130 via Ethernet. It reads analog signals from real-time operating data of the power generation equipment collected by other network devices and sends these analog signals to computer 130. These other network devices may include video surveillance equipment, environmental monitoring equipment, and unmanned inspection equipment installed in the new energy power plant. As one implementation, the data transmission channel between switch 140 and computer 130 can be Ethernet. The switch can be an 8-port switch or a 9-port switch.

[0037] In some embodiments, the chassis 100 may further include a heating branch 150 and a heat dissipation branch 160. The heating branch 150 is connected to the mains power output terminal via a second switch K2, and the heat dissipation branch 160 is also connected to the mains power output terminal via a second switch K2, so that the connection of the heating branch 150 and the heat dissipation branch 160 can be controlled by the second switch K2.

[0038] In one implementation, the heating branch 150 includes a heating element P and a first temperature control switch W1 connected in sequence. When the internal temperature of the chassis is lower than a preset first temperature threshold (e.g., -5℃, 0℃, etc.), the first temperature control switch W1 is turned on, thereby activating the heating branch 150 to heat the entire chassis. The heating element P can be a heater with a working power of 250W.

[0039] In one implementation, the heat dissipation branch 160 includes a heat dissipation device Q and a second temperature control switch W2 connected in sequence. When the internal temperature of the chassis is higher than a preset second temperature threshold (e.g., 25°C, 30°C), the second temperature control switch W2 is turned on, thereby activating the heat dissipation branch 160 to dissipate heat from the entire chassis. The heat dissipation device Q can be a cooling fan with a power of 5W.

[0040] In some embodiments, the chassis 100 is further provided with a plurality of power interfaces on its external panel. The power interfaces include at least one of the following: for example, a mains power input interface led out from the AC terminal of the AC-DC converter 110, which is preferably a three-hole socket, and the number of such interfaces can be one or more, with one being preferred in this embodiment; another example, a DC connection interface led out from the DC terminal of the AC-DC converter 110, the voltage of which is the output voltage of the DC terminal of the AC-DC converter 110, which is preferably an aviation plug, and the number of such interfaces can be one or more, with one being preferred in this embodiment; yet another example, a mains power output interface led out from the second switch K2, which is preferably an aviation plug, and the number of such interfaces can be one or more, with one being preferred in this embodiment.

[0042] In some embodiments, the chassis 100 is also provided with a multimedia interface HDMI on the outer panel. The multimedia interface HDMI is led out through the computer 130 and is used to connect to an external display device, so that the collected data can be displayed through the external display device. The interface is preferably an aviation plug, and there can be one or more of them. In this embodiment, one is preferred.

[0043] In some embodiments, the chassis 100 is further provided with a plurality of physical sensor interfaces on its external panel. The physical sensor interfaces include at least one of the following: for example, a sensor analog signal interface led out through an analog signal acquisition unit, through which analog signals from physical sensors can be received.
