For wind power generation, it can help wind farms improve power generation efficiency and operation and maintenance levels, and build an intelligent, safe and efficient energy system. At the same time, the application of the Internet of Things not only involves various links such as energy production, transmission and distribution, but also involves various levels such as wind farm management, monitoring, optimization, and services, forming a complex energy Internet of Things ecosystem.

[0034] It should be noted that the directional words appearing in this application are based on the relative position relationship shown in the drawings and cannot be used as an absolute limitation to this application.

[0035] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a control device based on IoT remote control switching operation provided in an embodiment of the present application. Figure 2 , Figure 2 This is a schematic diagram of the exterior of a housing provided in an embodiment of the present application. Figure 3 , Figure 3 The schematic diagram of a simple electrical connection between a control device based on remote control switching operation of the Internet of Things and a control circuit of a box-type transformer provided in an embodiment of the present application. The control device based on remote control switching operation of the Internet of Things provided in an embodiment of the present application comprises: a housing 11.

[0036] The controller 12 and the function module 13 are located in the housing 11. The function module 13 includes a first switch S1 and a voltage detection module 14. The first switch S1 includes but is not limited to a relay switch, and the voltage detection module 14 includes but is not limited to an optical coupler detection electric control module.

[0037] The housing 11 includes an external wiring female port 15 and a power female port 16 , and the power female port 16 is electrically connected to an external power source.

[0038] The functional module 13 is electrically connected to the control circuit of the box-type transformer through the external wiring female port 15. The control circuit of the box-type transformer is serially connected with a control button switch S2 for controlling the switching operation of the box-type transformer; wherein the first switch S1 and the control button switch S2 are connected in parallel.

[0039] The voltage detection module 14 detects the voltage on the control circuit of the box-type transformer; when the voltage detection module 14 detects that there is no voltage on the control circuit of the box-type transformer, it controls the external power supply to supply power to the control circuit of the box-type transformer. Figure 3 As shown, based on the voltage detection module 14 and the power access control module 17, the external power supply is used to power the control circuit of the box-type transformer. The switch S3 is used as a circuit connection switch in the circuit to realize the circuit connection under different schemes. It should be noted that Figure 3 The electrical connection method is only an example, and there are many specific connection relationships, which will not be repeated here.

[0040] The control button switch S2 is in the off state. When the voltage detection module 14 detects that there is voltage on the control circuit of the box-type transformer, or when an external power supply supplies power to the control circuit of the box-type transformer, the controller 12 controls the working state of the first switch S1 to control the switching operation of the box-type transformer.

[0041] Specifically, in the embodiment of the present application, the setting of the shell 11 is used to ensure that the control device based on the remote control switching operation of the Internet of Things can operate stably in the working environment, and its specific selection and design parameters can be determined according to the actual environmental requirements. Exemplarily, the material of the shell 11 includes but is not limited to ABS, the same or better material; the protection level of the shell 11 needs to reach IP66; the shell 11 needs to have the ability to prevent dust, dirt, and interference, and its wear resistance, scratch resistance, and impact resistance meet the requirements of extreme use environments. The size design of the shell 11 needs to ensure the installation of various components in the control device based on the remote control switching operation of the Internet of Things, set a stable fixed structure, and isolate the battery and the circuit board to a certain extent. The opening on the circuit board should be accurate and appropriate. The shell 11 uses a non-fully enclosed design, and is assembled and fixed using screws, anchor bolts and other mechanisms to ensure that the shell can be opened and closed normally during subsequent maintenance and repair. The material and design strength of the shell 11 meet the design parameters.

[0042] In a possible implementation, the power supply mother port 16 is electrically connected to the external power supply through an external wire, and the functional module 13 is electrically connected to the control circuit of the box-type transformer through the external wire mother port 15 and the external wire. That is, the external wire on the control device based on the remote control switching operation of the Internet of Things in the embodiment of the present application includes a connecting wire connecting the functional module 13 in the control device based on the remote control switching operation of the Internet of Things with the control circuit of the box-type transformer and a connecting wire connecting the power supply mother port 16 with the external power supply. The specific selection and design parameters of the external wire are that the cable length must be sufficient to allow the control device based on the remote control switching operation of the Internet of Things to be placed on the ground for operation, one end of the external wire adopts a pluggable interface to be connected to the control device based on the remote control switching operation of the Internet of Things, and it is not easy to loosen and fall after connection, and the other end adopts a certain structure to fix it to both sides of the control button switch and the output end of the external power supply, and it is necessary to ensure the connection operation to avoid the risk of electric shock.

[0043] The external wiring can be removed and replaced. The connecting wires connected to the control circuit of the box-type transformer and the connecting wires connected to the external power supply. These two types of external wiring and equipment connection ends need to use different types of interface designs to prevent misoperation. The other end should select a reliable connection structure according to the connection method, and the external wiring meets the design parameters.

[0044] In one possible implementation, the external power supply is a UPS (Uninterruptible Power System) power supply, which refers to a power supply device that will not be interrupted by a short power outage, can always supply high-quality power, and effectively protect precision instruments. That is to say, in the embodiment of the present application, a UPS power supply is prepared as a backup power supply for the box-type transformer control circuit when the power fails. Its specific selection and design parameters are to meet the maximum load of 600W and above, output industrial frequency voltage, the waveform is a sine wave, support AC140V to 290V wide voltage input, and have lightning protection and electrophoresis protection functions. The output interface of the UPS power supply should be consistent with the external wiring to achieve the purpose of reliable and stable connection.

[0045] In a possible implementation, the controller 12 and the functional module 13 are integrated on the same circuit board 18 to improve the integration of the control device based on the remote control switching operation of the Internet of Things, reduce the size, and achieve the purpose of portability.

[0046] In one possible implementation, see Figure 4 , Figure 4 A schematic diagram of another control device for remote switching operation based on IoT provided in an embodiment of the present application is shown in FIG. Figure 5 , Figure 5 The control device based on the remote control switching operation of the Internet of Things also includes: a charging and discharging module 19 located in the housing 11, and a power supply mother port 20 located on the housing 11.

[0047] The charging and discharging module 19 is used to supply power to various components in the control device based on the remote control switching operation of the Internet of Things.

[0048] See also Figure 6 , Figure 6 A schematic diagram of the structure of another control device based on remote control switching operation of the Internet of Things provided in an embodiment of the present application. The control device based on remote control switching operation of the Internet of Things also includes: a battery 21.

[0049] Specifically, the selection parameters of the charging and discharging module 19 can select a suitable electronic control chip, and use a standard Type-C input interface for charging. Considering the program burning and subsequent maintenance of the control device based on the remote control switching operation of the Internet of Things, this port is also used for serial port burning. The electronic control part selects a suitable voltage control chip according to the working voltage requirements of the battery and other components. When drawing the circuit board for the charging and discharging module 19, a separate power supply layer and ground layer are designed. The battery 21 is connected to the charging and discharging module 19, and when the Type-C interface is not used for power supply, it is used as the power supply for the equipment to ensure the normal operation of the device.

[0050] The charging and discharging module 19 performs charging control of the control device based on the remote control switching operation of the Internet of Things, switching control of battery power supply and power supply, and voltage transformation to provide a suitable voltage for the operation of the control device based on the remote control switching operation of the Internet of Things. The module charging port is a standard Type-C input female port, with an input voltage range of 5 to 5.5V, a charging cut-off voltage of (4.2V / 4.35V) ±0.5%, a charging current of 2.4A±5%, and an output voltage of 5±0.15V and 3.3±0.15V (with cable loss compensation) to meet the power supply requirements of the controller and other modules. The output voltage ripple is 100mV, the output current is 2A, the boost conversion efficiency is more than 90%, and the battery-side quiescent current must be less than 30uA.

[0051] The specific selection and design parameters of battery 21 are that the battery capacity meets the requirements for the device to operate for more than 3 hours, the nominal voltage is 3.7±0.5V, the fully charged voltage is 4.2±0.5V, it must include over-discharge protection and over-current protection, the electrical limit voltage is 4.25V, the discharge temperature range is -20℃ to 60℃, and the maximum discharge current is 2A.

[0052] In one possible implementation, the controller 12 includes but is not limited to a microcontroller SoC module. When the microcontroller SoC module is selected to draw a circuit board, a complete driving circuit needs to be designed, and a separate control switch needs to be designed for burning. When the switch is closed, the burning mode is entered, and the burning is performed through the serial port. The number and function of the IO ports meet the functional requirements of the device, and the unused IOs are reasonably closed. At the same time, the circuits of different IO ports are designed in accordance with their communication protocols when they are drawn. Since the control device based on the remote control switching operation of the Internet of Things needs to be controlled through the Internet, the microcontroller SoC module needs to be able to communicate wirelessly. If this requirement cannot be met, a radio frequency component and its supporting circuit design can be added to the module and controlled by a wireless remote control. It can be understood that the controller 12 has a wireless communication component. The wireless communication component is a WIFI component and / or a Bluetooth component.

[0053] Among them, the microcontroller SoC module is the core computing part of the control device based on the remote control switching operation of the Internet of Things. According to the implementation requirements of the control device based on the remote control switching operation of the Internet of Things, it has 802.11b / g / n WIFI function, and the WIFI antenna is an onboard antenna or an external antenna. The specific selection must meet the requirement of a transmission distance of more than 50m, a power supply voltage of 3V to 3.6V (typical value 3.3V), an operating temperature of -20℃ to 85℃, and SPI Flash is required to meet the requirement of stable operation of the internal program. The number of IO ports, digital-to-analog conversion, communication protocol, etc. must meet the requirements of other modules of the control device based on the remote control switching operation of the Internet of Things.

[0054] Functional module 13 meets the functions of a control device based on IoT remote control switching operation, including switch function, voltage detection, external wiring interface access, Type-C interface serial communication burning, and some logic operations implemented by hardware. The functional module 13 also sets safety protection and physical anti-misoperation mechanism, which is specifically divided into an AC power area and a control area. The AC power area needs to be connected to the box-type transformer control circuit through an external connection line, and uses 220V industrial frequency AC power, so the two areas are set up with safe and reliable isolation.

[0055] Functional module 13 is the main logic control part of the control device based on the remote control switching operation of the Internet of Things. According to the technical performance parameter requirements, the AC area of ​​the functional module 13 is connected to the female port through the external wire, and then detected by the voltage detection module of the functional module. The detection result signal is fed back to the microcontroller SoC module through the control area. According to the detection result, it is determined whether the external power supply needs to be connected. If there is no voltage, it is power failure. The functional module connects the UPS power supply connected to the external wire to the AC area as a power supply through switch components such as relays; if there is no power failure, the UPS power supply continues to be disconnected and the box-type transformer control circuit is powered by its own power supply. After the voltage condition of the box-type transformer control circuit is determined and the on-off setting of each switch is completed, the first switch connected in parallel with the control button switch of the box-type transformer switching operation is actuated to control the switching operation of the box-type transformer.

[0056] The components and sensor signals used in the above functions are connected to the microcontroller SoC module through the control area, and external indicator lights are set to indicate each link and situation. Functional module 13 Due to the possibility of electric shock from industrial frequency AC, there must be reliable isolation between the AC area and the control area. At the same time, the hardware design must ensure safety and reliability during use. At the same time, the on-off timing of various switches must be reasonable, and physical methods are used for logical judgment when necessary to avoid misoperation.

[0057] There are two optional schemes for wireless communication. The first is to control through internal web pages. Specifically, a local area network is set up through the onboard Wifi of the microcontroller SoC module, an internal API server is established, and the control page website and the control interface corresponding to the function are mounted on the server. The user connects to the local area network and accesses the control page through the URL. The status and feedback of the control device based on the current IoT remote control switching operation are viewed, and the control interface of each function is accessed according to the button click on the page, thereby triggering the function and completing the control of the control device based on the IoT remote control switching operation. The other is to use the hardware RF module to judge the user's operation by reading the signal of the wireless controller to trigger the function. The user needs to judge the current operating status of the device through the indicator light on the control device based on the IoT remote control switching operation. The above functions are triggered stably and reliably without indication errors, and an anti-misoperation function is set.

[0058] According to the signal transmitted by the voltage detection module 14 in the functional module 13, a logical judgment is made, the access circuit situation is analyzed, and then the state of each switch and other components in the functional module 13 is controlled to complete the action. Specifically:

[0059] When the control device based on the remote control switching operation of the Internet of Things is connected to the control loop of the box-type transformer, the feedback of the receiving voltage detection module 14 determines whether there is a power failure in the control loop of the box-type transformer, and then controls various switching elements such as relays to control whether to connect to the UPS power supply or safely isolate and disconnect the UPS power supply. After the circuit interface of the device is determined, the action preparation status is transmitted through a page or indicator light. After the action interface accesses or receives the action corresponding signal of the wireless controller, the first switch connected in parallel on both sides of the box-type transformer switching button control switch is controlled to simulate the on-off status after the button is pressed, thereby completing the device action.

[0060] A control device based on IoT remote control switching operation provided in an embodiment of the present application is an on-site power device for opening and closing switches to ensure personal safety involving the Internet of Things and intelligent technologies, including device hardware and its Internet of Things program. The device can replace employees in performing on-site opening and closing operations of box-type transformers. At the same time, remote control through wireless networking or radio frequency remote control can intuitively view the status of the box-type transformer and the device itself. The operation is simple, and the logical judgment ability of the device can avoid the risk of misoperation, thereby improving the safety of electrical equipment, providing technical support for the safe operation of the power system, and contributing to the intelligent upgrade of the power industry.
