Especially in the management and maintenance of control cabinets, traditional manual operation and local automatic operation methods have gradually failed to meet the needs of modern industry for high efficiency and intelligence. Therefore, it is particularly important to develop a system that can achieve remote monitoring and control.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0041] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] As mentioned in the background technology, existing control cabinets usually include structural designs such as air outlets and air inlets to ensure heat dissipation and air circulation of the equipment. However, these designs often only consider physical environmental factors, while ignoring the need for remote control of electrical equipment inside the control cabinet. In traditional control cabinets, operators need to go directly to the site to start and stop the equipment, adjust parameters, and other operations, which not only increases labor costs, but also reduces the response speed and flexibility of the system.

[0044] To improve the above problems, the present application proposes a remote control system and method for a control cabinet, in which the controller accurately converts the digital signal into a switch signal, thereby driving the relay or contactor to precisely control the device. This precise control helps to ensure that the device operates according to the predetermined parameters and procedures, and improves the stability of the production process and the product quality. In the control system, the relay and the contactor act as an actuator, and when the device is abnormal, the emergency stop command or error correction command issued by the controller cuts off the contact end power circuit or opens the contact end protection circuit to protect the device from damage. This protection function helps to extend the service life of the device and reduce maintenance costs. The response speed of the relay and the contactor is fast, which can meet the needs of real-time control. By quickly responding to the instructions of the controller, the relay and the contactor can quickly adjust the operating state of the device and improve the response speed and efficiency of the system. The contactor module and the relay module play the role of isolation relay and convert the circuit and amplify the voltage to achieve precise control of the device and ensure that the device operates according to the predetermined parameters, which brings many benefits to the modern industrial automation system, including precise control, protection of equipment, improved response speed, easy integration, energy saving and environmental protection, strong flexibility, and easy maintenance and management. These benefits have jointly promoted the development and application of modern industrial automation technology.

[0045] See also Figure 1-5 As shown, a remote control system for a control cabinet according to an embodiment of the present application includes:

[0046] A control cabinet 1, wherein an air outlet 2 is provided on one side of the control cabinet 1, a rotating assembly 3 is provided at the air outlet 2, an air inlet 4 is provided on the side of the control cabinet 1 away from the air outlet 2, a fan 5 is provided on the control cabinet 1, the fan 5 is provided at the air inlet 4 or at the air outlet 2, and an electric door 6 is provided on the end face of the air inlet 4 away from the control cabinet 1;

[0047] A controller 7, wherein the controller 7 is disposed in the control cabinet 1 and is used for remote communication, data processing, input collection and output control;

[0048] A relay module 8, wherein the coil input end of the relay module 8 is electrically connected to the control output end of the controller 7, and the contact output end of the relay module 8 is electrically connected to the actuator electric power input end or the contactor coil input end;

[0049] A contactor module 15, wherein the coil input end of the contactor module 15 is electrically connected to the control output end of the controller 7 or the contact output end of the relay module 8, and the contact output end of the contactor module 15 is electrically connected to the actuator power input end;

[0050] The power module 16 is used to provide power supply and control power supply.

[0051] Specifically, the control cabinet 1 is the main part of the whole system, which is used to install and protect other components. An air outlet 2 is set on one side of the control cabinet to discharge the internal heat. A rotating component 3 is installed at the air outlet, which may be used to control the wind direction or wind speed. An air inlet 4 is set on the other side of the control cabinet, where a fan 5 is installed to suck the external air into the control cabinet. An electric door 6 is also set on the end face of the air inlet away from the control cabinet, which may be used to control the opening and closing of the air inlet. The controller 7 is a device set inside the control cabinet, which is responsible for remote communication, data processing, input signal collection and control output signals. The controller is the core of the whole system, which controls the work of other components according to the received instructions and data. The coil input end of the relay module 8 is electrically connected to the control output end of the controller 7, and its contact output end is electrically connected to the electric power input end of the actuator or the contactor coil input end. The function of the relay module is to control the action of the actuator according to the instructions of the controller, such as starting or stopping a certain device. The coil input end of the contactor module 15 can be electrically connected to the control output end of the controller 7 or the contact output end of the relay module 8, and its contact output end is electrically connected to the electric power input end of the actuator. The function of the contactor module is also to control the action of the actuator according to the instructions of the controller, but it may be used for equipment with higher power or occasions requiring high voltage control. The power supply module 16 provides power support for the entire system. It is electrically connected to the control power supply module and is used to provide a stable DC power supply for the controller and other electronic devices.

[0052] The fan 5 installed at the air outlet 2 exhausts air to the outside, which has more advantages than the fan installed at the air inlet 4: one is that the entire cabinet cavity can be used as an enlarged throat of the air inlet 4 to achieve full circulation of gas in the cabinet cavity and facilitate heat dissipation; the other is that it is beneficial to the outdoor installation layout, and the high pressure at the exhaust port is conducive to blowing away water droplets and mist and forcing it to leave the cabinet. The cabinet air inlet 4 is also lower than the inlet pressure of the fan 5, thereby avoiding the inhalation of water vapor.

[0053] The power supply is usually AC with a relatively high voltage, and the control power supply is usually DC or AC and is stepped down from the high voltage of the power supply.

[0054] In some specific embodiments, the rotating assembly 3 includes:

[0055] A first electric rotating shaft 9, which is arranged at the top of the air outlet 2, and is arranged horizontally, and the mounting ends on both sides of the first electric rotating shaft 9 are respectively fixedly connected to the inner wall of the air outlet 2;

[0056] A first sealing plate 10, the first sealing plate 10 is arranged at the bottom of the first electric rotating shaft 9, the top of the first sealing plate 10 is fixedly connected to the rotating end of the first electric rotating shaft 9, and both sides of the first sealing plate 10 are in contact with the inner wall of the air outlet 2;

[0057] The second electric rotating shaft 11 is arranged at the bottom of the first sealing plate 10, the second electric rotating shaft 11 is arranged horizontally, and the mounting ends on both sides of the second electric rotating shaft 11 are respectively fixedly connected to the inner wall of the air outlet 2, and the bottom of the first sealing plate 10 is in contact with the top of the second electric rotating shaft 11;

[0058] The second sealing plate 12 is arranged at the bottom of the second electric rotating shaft 11, the top of the second sealing plate 12 is rotatably fixedly connected to the bottom of the second electric rotating shaft 11, the bottom of the second sealing plate 12 abuts against the inner bottom wall of the air outlet 2, and the two sides of the second sealing plate 12 abut against the inner wall of the air outlet 2.

[0059] In some specific embodiments, the diameters of the first electric rotating shaft 9 , the first sealing plate 10 , the second electric rotating shaft 11 , and the second sealing plate 12 match the inner diameter of the air outlet 2 .

[0060] In some specific embodiments, the top of the second electric rotating shaft 11 matches the bottom mating surface of the first sealing plate 10 in shape and can be abutted and fitted.

[0061] Specifically, since the diameters of the first electric rotating shaft 9, the first sealing plate 10, the second electric rotating shaft 11 and the second sealing plate 12 are matched with the inner diameter of the air outlet 2, it is ensured that the air outlet can be completely closed to prevent air circulation when it is closed. This closely matched design can significantly improve the sealing effect and reduce energy loss, which is particularly important in occasions where the temperature inside the control cabinet needs to be maintained or it needs to be waterproof and dustproof. By fixing each component (such as the first electric rotating shaft 9, the first sealing plate 10, the second electric rotating shaft 11 and the second sealing plate 12) to the inner wall of the air outlet 2, the structure of the entire rotating assembly is more stable. This fixed connection method reduces the possibility of loosening or misalignment caused by vibration or other external factors, thereby improving the reliability of the entire system and the stability of long-term operation. The design of double-layer electric rotating shafts and sealing plates can achieve more complex functions without increasing the additional space occupation. For example, the first layer may be responsible for coarse adjustment of ventilation volume, while the second layer is for fine adjustment. Such a design makes the control more precise and also optimizes the spatial layout inside the control cabinet. When the rotating assembly 3 needs to be maintained or replaced, it can be disassembled and reassembled relatively easily due to its reasonable structural design and clear connections between the various components. This not only reduces maintenance costs, but also shortens the downtime of the equipment. Due to the use of an electric rotating shaft, fast and precise opening and closing actions can be achieved. This is very important for application scenarios where the ventilation volume needs to be adjusted frequently, because it can respond quickly to environmental changes and keep the environment inside the control cabinet stable. Good sealing performance can prevent dust, moisture and other contaminants from entering the interior of the control cabinet, thereby protecting sensitive electronic components from damage. In addition, if the control cabinet is used to store flammable or toxic substances, good sealing can also prevent these substances from leaking into the external environment, ensuring personnel safety and environmental protection.

[0062] In some specific embodiments, the electric door 6 includes:

[0063] A third electric rotating shaft 13, which is disposed at the top of the air inlet 4, and the mounting ends on both sides of the third electric rotating shaft 13 are respectively fixedly connected to the inner side walls of the air inlet 4;

[0064] The sealing door 14 has a top that is fixedly connected to a bottom rotating end of the third electric rotating shaft 13 .

[0065] In some specific embodiments, the axial cross-sectional shape of the sealing door 14 is the same as the axial cross-sectional shape of the air inlet 4 , and the outer diameter of the sealing door 14 matches the inner diameter of the air inlet 4 .

[0066] Specifically, since the axial cross-sectional shape of the sealing door 14 is the same as the axial cross-sectional shape of the air inlet 4 and the outer diameters match, when the sealing door is closed, a tight sealing effect can be achieved. This helps prevent air leakage and maintain the stability of the internal environment of the control cabinet. The mounting ends on both sides of the third electric rotating shaft 13 are fixedly connected to the inner side walls of the air inlet 4 respectively, and this fixing method increases the stability and reliability of the entire electric door structure. Reduce the possibility of loosening or misalignment caused by vibration or other external factors. The design of the electric rotating shaft and the sealing door can achieve precise opening and closing control without increasing the additional space occupation. Such a design makes the control more precise and also optimizes the spatial layout inside the control cabinet. When the electric door needs to be maintained or replaced, it can be disassembled and reassembled relatively easily due to its reasonable structural design and clear connections between the various components. This not only reduces maintenance costs, but also shortens the downtime of the equipment. Due to the use of the electric rotating shaft, fast and precise opening and closing actions can be achieved. This is very important for application scenarios that require frequent adjustment of ventilation volume, because it can quickly respond to environmental changes and keep the environment inside the control cabinet stable. Good sealing performance can prevent dust, moisture and other contaminants from entering the control cabinet, thereby protecting sensitive electronic components from damage.

[0067] In some specific embodiments, the axes of the first electric rotating shaft 9 , the first sealing plate 10 , the second electric rotating shaft 11 , and the second sealing plate 12 coincide with each other.

[0068] In some specific embodiments, the first electric rotating shaft 9 , the second electric rotating shaft 11 , the third electric rotating shaft 13 , and the fan 5 are all electrically connected to the relay module 8 or the contactor module 15 .

[0069] Specifically, high-power fan motors require high-power power supply. Contactors can be used to easily access power supply. For example, instead of using low-voltage electricity through a switching power supply or transformer, relatively high-voltage AC electricity can be used directly, thereby reducing the load on the switching power supply or transformer and extending its service life. Therefore, the contactor modules we deployed are used in the remote control layout and methods of the control cabinet itself.

[0070] In some specific embodiments, the actuator is a relay connected to the equipment circuit in the control cabinet 1, and the first electric rotating shaft 9, the second electric rotating shaft 11, the third electric rotating shaft 13, and the fan 5 are all electrically connected to the controller 7 through corresponding relays.

[0071] Specifically, by integrating the control of multiple devices into the controller 7, centralized control and management of these devices can be achieved. This centralized control method simplifies the operation process and improves management efficiency. The relay, as an actuator, can accurately control the start, stop and operation status of each device according to the instructions of the controller 7. This precise control helps to ensure that the equipment operates according to the predetermined parameters and procedures, improve the stability of the production process and product quality. The controller 7 can receive feedback signals from each device in real time and adjust the operating status of the equipment in a timely manner according to these signals. This real-time response capability helps to discover and solve potential problems in a timely manner and reduce the risk of failure.

[0072] The present application also discloses a remote control method for a control cabinet, comprising the following steps:

[0073] S1, the controller 7 monitors the network delay and jitter, determines the real-time performance and stability of the network by analyzing the network delay and jitter data, and feeds back the judgment result to the device interface corresponding to the user;

[0074] S2, the controller 7 receives the remote command issued by the device corresponding to the user, and processes the command and outputs the control relay module 8 or the contactor module 15;

[0075] S3, the contactor controls the equipment in the controller cabinet 1 or the relay controls the equipment in the controller cabinet 1 or the contactor module 15 to perform corresponding work.

[0076] Specifically, by real-time monitoring of network delay and jitter, the system can ensure the stability and real-time nature of data transmission, thereby improving the user experience when using the remote control system. When the network is delayed or jittered, the system can quickly detect and notify the user, so that the user can understand the network status in time and take corresponding measures. By analyzing the network delay and jitter, the system can optimize the network, improve data transmission efficiency, and reduce the failure rate. Real-time monitoring and analysis of network conditions can help to discover potential network problems, thereby preventing failures in advance and enhancing the reliability of the system. Users only need to issue instructions through remote devices to control the equipment inside the control cabinet without on-site operation, which greatly simplifies the operation process. Through remote control, users can operate the equipment anywhere, saving time and cost and improving work efficiency. The remote control system can be integrated with other systems to achieve more advanced functions and applications, such as automated production lines, smart buildings, etc. The relay module can convert digital signals into analog signals and drive the relay to accurately control the equipment to ensure that the equipment operates according to the predetermined parameters. As an actuator, the relay can cut off the power supply when the controller issues an erroneous instruction to protect the equipment from damage. The relay has a fast response speed, which can meet the needs of real-time control and improve the response speed and efficiency of the system.

[0077] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
