Description

Technical Field

[0001] This invention relates to the field of heating technology, specifically to a heating method and system for industrial plants. Background Technology

[0002] High-ceilinged industrial buildings generally refer to factory buildings with a clear height greater than 5 meters. These buildings are characterized by high ceilings, large spans, large window and door areas, and high permeability loads, resulting in high heating loads in winter, large indoor temperature gradients, severe temperature stratification along the vertical direction, and a warmer upper floor and colder lower floor. When hot water heating is used, water-based radiators are generally installed under the window sills on the exterior of the building. Heat exchange occurs through natural convection. However, the heating capacity of a single water-based radiator is low, the number of radiators is large, the heating radiation range is small, and hot air rises into the top of the factory building, resulting in ineffective heating of the working areas.

[0003] In existing technologies, heating can be achieved by using traditional electric radiant heating panels to heat the entire factory area.

[0004] However, traditional electric radiant heating panels require installation throughout the entire factory area, increasing construction costs. During daily operation, the activation control logic for these panels is simple, typically requiring all panels to be activated or only certain sections to be activated, resulting in a high number of panels being in use and further increasing operating costs. Summary of the Invention

[0005] This invention provides a heating method and system for industrial plants to solve the problem of high construction and operating costs in the prior art for heating plants using electric radiant heating panels.

[0006] In a first aspect, the present invention provides a method for heating an industrial plant, comprising the following steps: The main activity areas of personnel within the factory building are identified, and an intelligent identification system is installed in these areas to determine frequently used personnel zones. Electric heating radiant panels are also installed, with a greater number of panels in frequently used zones than in other areas. Each electric heating radiant panel has a first working state, a second working state, and a closed state. The operating temperature of the first working state is lower than that of the second working state. Based on the factory's operating status, the intelligent identification system controls the electric heating radiant panels to switch between these states.

[0007] Beneficial Effects: By analyzing the production process within the factory, the main activity areas of personnel within the factory building are initially determined. An intelligent identification system is installed in these areas. Through monitoring and identification by the intelligent identification system over a period of time, and summarizing the data using computer vision recognition technology, the frequently used activity areas of personnel are identified. The number of electric radiant heating panels installed in these frequently used areas is greater than the number installed in other areas. This rational zoning and arrangement of the electric radiant heating panels reduces construction costs. During operation, based on the factory's operating status, the intelligent identification system controls the electric radiant heating panels to switch between a first operating state, a second operating state, and an off state. This ensures that the factory's heating system operates at a low load daily, reducing heat waste and lowering operating costs. The industrial plant heating method provided by this invention solves the problem of high construction and operating costs associated with existing technologies using electric radiant heating panels in factories.

[0008] In one alternative implementation, when installing the electric radiant heating panels, the number of panels arranged in areas where people frequently move around is set according to the requirement of an indoor temperature of 15°C, while the number of panels arranged in other areas is set according to the requirement of an indoor temperature of 5°C.

[0009] Beneficial effects: In areas with frequent personnel activity, the number of electric radiant heating panels is set at a smaller number and denser to meet the indoor temperature requirement of 15℃. In other areas, the number of electric radiant heating panels is set at a smaller number and sparser to meet the indoor temperature requirement of 5℃. Compared with the traditional uniform standard arrangement of electric radiant heating panels throughout the factory area, the construction cost is reduced while ensuring the heating effect.

[0010] In one optional implementation, the intelligent recognition system includes a camera and a control module. The camera is communicatively connected to the control module. The camera is installed above the main activity area of ​​personnel. The control module uses computer vision recognition technology to summarize and analyze the image information collected by the camera to determine the areas where personnel frequently move. The control module is communicatively connected to the temperature controller of the electric heating radiant panel. During the factory production process, the camera is used to identify personnel activities, and the control module controls the opening or closing of the electric heating radiant panel.

[0011] Beneficial effects: The intelligent recognition system's cameras cover the entire activity area of ​​personnel. Through monitoring and recognition over a period of time, the cameras transmit the collected image information to the control module. The control module uses computer vision recognition technology to summarize the areas where personnel frequently move around. Based on the distribution of these areas, it can arrange the electric heating radiant panels in zones. During factory production, when personnel pass through the work area, the cameras can identify their activity and transmit the data to the control module. The control module then sends instructions to the electric heating radiant panels in that work area, controlling them to activate high-temperature mode. The electric heating radiant panels in other areas are either not activated or activated at low temperatures. The factory's heating system can maintain a low-load operation during normal times, only operating at high temperatures in areas where people are present. This ensures the normal work of workers while avoiding the waste of heat in other areas of the factory.

[0012] In one optional implementation, when there is no personnel activity in the factory or when the factory is not in operation at night, the intelligent identification system controls the electric heating radiation panel to open or close or to enter a first working state. When the electric heating radiation panel enters the first working state, the temperature inside the factory reaches 5°C for duty.

[0013] Beneficial effects: The intelligent identification system can detect when there is no human activity in the factory for a long time, or when the system is manually set to not operate at night or on holidays according to the control module, thereby controlling the electric heating radiant panel to turn off or on in its first working state, reducing heat waste and lowering operating costs; when the electric heating radiant panel is on in its first working state, it operates at a low temperature, so that the factory can reach a duty temperature of 5°C, which ensures the temperature requirements for duty. At the same time, it can achieve rapid heating when the factory starts production.

[0014] In one optional implementation, during factory operation, the intelligent identification system controls the second working state of the electrothermal radiation panel to be partially or fully activated, so that the factory reaches a working operating temperature of 15°C.

[0015] Beneficial effects: During factory operation, the intelligent recognition system controls the electric heating radiation panels to partially or fully activate their second working state based on the personnel activities identified by the camera, so that the personnel activity area in the factory reaches the working operating temperature of 15℃, ensuring the normal daily work of personnel.

[0016] In one alternative implementation, when the factory is running, the intelligent identification system detects a person passing by and controls the electric heating radiation panels in the area where the person is active to turn on the second working state, while the electric heating radiation panels in other areas are either turned off or turned on in the first working state.

[0017] Beneficial effects: When personnel pass through the work area during factory operation, the intelligent recognition system can identify personnel activity and send instructions to the electric radiant heating panels in that work area to control the electric radiant heating panels to activate the second working state, i.e., the electric radiant heating panels operate at high temperature. The electric radiant heating panels in other areas are either not activated or are in the first working state, i.e., the electric radiant heating panels operate at low temperature. The heating system in the factory can maintain a low load operation on a daily basis, and only operate at high temperature in areas where people are present. This ensures that workers can work normally on a daily basis and avoids the waste of heat in other areas of the factory.

[0018] Secondly, the present invention also provides a heating system, including: an intelligent identification system and an electric radiant panel, wherein the intelligent identification system is used to identify areas where personnel frequently move within the factory; multiple electric radiant panels are installed within the factory, and the electric radiant panels are communicatively connected to the intelligent identification system, wherein the number of electric radiant panels arranged in areas where personnel frequently move is greater than the number of electric radiant panels arranged in other areas.

[0019] Beneficial Effects: By monitoring and identifying data over a period of time through an intelligent recognition system, and summarizing the data using computer vision recognition technology, areas of frequent human activity can be determined. The number of electric radiant heating panels deployed in these areas is greater than in other areas. This rational zoning and deployment of the panels reduces construction costs. During operation, the intelligent recognition system controls the electric radiant heating panels to switch between a first working state, a second working state, and an off state based on the factory's operating status. This ensures the factory's heating system operates at a low load daily, reducing heat waste and lowering operating costs. The heating system provided by this invention solves the problem of high construction and operating costs in existing technologies using electric radiant heating panels for factory heating.

[0020] In one optional implementation, a temperature controller is provided on the electrothermal radiant plate, and the temperature controller is electrically connected to the intelligent identification system.

[0021] Beneficial effects: The intelligent identification system controls the temperature and operating status of the electric heating radiant panel through a thermostat.

[0022] In one optional embodiment, a power supply mechanism is further included, which is electrically connected to the intelligent identification system and the electrothermal radiation panel. The power supply mechanism includes a photovoltaic module and an energy storage device. The photovoltaic module is installed on the roof of the factory building. The energy storage device is electrically connected to the photovoltaic module and to the electrothermal radiation panel and the intelligent identification system.

[0023] Beneficial effects: Photovoltaic modules are set up as a distributed photovoltaic system on the factory roof, converting solar energy into electrical energy, which is stored in an energy storage device to provide power to the electric heating radiant panels, realizing green electricity direct supply to the heating system, which is energy-saving and environmentally friendly.

[0024] In one alternative implementation, the electrothermal radiant panel is suspended from the wall and / or roof of the factory building.

[0025] Beneficial effects: When electric radiant heating panels are suspended on walls or roofs, they can reduce the amount of floor space occupied in the factory while ensuring heating performance. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.

[0031] According to an embodiment of the present invention, in one aspect, a method for heating an industrial plant is provided, comprising the following steps: The main activity areas of personnel within the factory building are determined, and an intelligent identification system is installed in these areas to identify frequently used personnel areas. Electric heating radiant panels 1 are installed, with a greater number of panels 1 arranged in the frequently used areas than in other areas. Each electric heating radiant panel 1 has a first working state, a second working state, and a closed state. The operating temperature of the first working state is lower than that of the second working state. Based on the factory's operating status, the intelligent identification system controls the electric heating radiant panels 1 to switch between the first working state, the second working state, and the closed state.

[0032] In practice, the factory's production process is analyzed to initially determine the main activity areas of personnel within the factory building. An intelligent identification system is installed in these areas. Through monitoring and identification by the intelligent identification system over a period of time, and by summarizing the data using computer vision recognition technology, frequently used personnel activity areas are identified. The number of electric radiant heating panels 1 arranged in these frequently used areas is greater than the number arranged in other areas. This rational zoning arrangement of the electric radiant heating panels 1 reduces construction costs. Based on the factory's operating status, the intelligent identification system controls the electric radiant heating panels 1 to switch between a first working state, a second working state, and an off state, enabling the factory's heating system to operate at a low load daily, reducing heat waste and lowering operating costs. The industrial plant heating method provided in this embodiment solves the problem of high construction and operating costs associated with using electric radiant heating panels 1 for factory heating in existing technologies.

[0033] It should be further explained that the first working state of the electric radiant heating panel 1 is low temperature operation, and the second working state of the electric radiant heating panel 1 is high temperature operation. The low temperature operation and high temperature operation of the electric radiant heating panel 1 are set according to the heat load of the actual use environment and the heating temperature to be achieved.

[0034] In one embodiment, when installing the electric radiant heating panels 1, the number of panels 1 arranged in areas with frequent personnel activity is set according to the requirement of an indoor temperature of 15°C, while the number of panels 1 arranged in other areas is set according to the requirement of an indoor temperature of 5°C. In areas with frequent personnel activity, the number of panels 1 arranged according to the requirement of an indoor temperature of 15°C is smaller and more numerous and denser, while in other areas, the number of panels 1 arranged according to the requirement of an indoor temperature of 5°C is smaller and sparser. Compared to a uniform standard arrangement of the panels 1 throughout the entire factory area, this reduces construction costs while ensuring heating performance. Furthermore, as an alternative implementation, the indoor temperatures to be achieved in areas with frequent personnel activity and other areas can be set to other values ​​according to the design requirements of the actual environment.

[0035] In one embodiment, the intelligent recognition system includes a camera 2 and a control module 3. The camera 2 is communicatively connected to the control module 3. The camera 2 is installed above the main activity area of ​​personnel. The control module 3 summarizes and analyzes the image information collected by the camera 2 using computer vision recognition technology to determine the areas where personnel frequently move. The control module 3 is communicatively connected to the temperature controller 4 of the electric heating radiant panel 1. During the factory production process, the camera 2 is used to identify personnel activities, and the control module 3 controls the opening or closing of the electric heating radiant panel 1. The intelligent recognition system's camera 2 covers the entire activity area of ​​personnel. Through monitoring and recognition by the camera 2 over a period of time, the collected image information is transmitted to the control module 3. The control module 3 uses computer vision recognition technology to summarize the frequently active areas of personnel, and thus, based on the distribution of these areas, it can achieve zoned arrangement of the electric heating radiant panels 1. During factory production, when personnel pass through the work area, the camera 2 can identify personnel activity and transmit the data to the control module 3. The control module 3 then sends instructions to the electric heating radiant panels 1 in that work area, controlling them to activate high-temperature mode. The electric heating radiant panels 1 in other areas are either not activated or activate low-temperature mode. The factory's heating system can maintain a low-load operation during normal times, only operating at high temperature in areas where people are present, ensuring the normal daily work of workers while avoiding heat waste in other areas of the factory.

[0036] In one embodiment, when there is no personnel activity in the factory or during nighttime operation, the intelligent identification system controls the electric heating radiant panel 1 to turn on / off or enter a first working state. When the electric heating radiant panel 1 is in the first working state, the factory floor reaches a standby temperature of 5°C. The intelligent identification system detects that there is no personnel activity in the factory floor for an extended period, or manually sets the floor to not operate during nighttime or holidays according to the control module 3, thereby controlling the electric heating radiant panel 1 to turn off or enter the first working state, reducing heat waste and lowering operating costs. When the electric heating radiant panel 1 is in the first working state, it operates at a low temperature, ensuring that the factory floor reaches a standby temperature of 5°C, thus guaranteeing the required temperature for standby operation. Simultaneously, it enables rapid heating when the factory begins production.

[0037] In one embodiment, during factory operation, the intelligent identification system controls the second working state of the electric heating radiant panel 1 to be partially or fully activated, thereby maintaining an operating temperature of 15°C within the factory. Based on personnel activity detected by the camera 2, the intelligent identification system controls the second working state of the electric heating radiant panel 1 to be partially or fully activated, ensuring high-temperature operation of the panel and maintaining a 15°C operating temperature in the personnel activity area within the factory, thus guaranteeing normal daily work for personnel.

[0038] In one embodiment, during factory operation, when the intelligent recognition system detects personnel passing by, it controls the electric radiant heating panels 1 in the personnel activity area to activate a second working state, while the electric radiant heating panels 1 in other areas remain off or activate a first working state. When personnel pass through the work area, the intelligent recognition system can identify personnel activity and send instructions to the electric radiant heating panels 1 in that work area, controlling the electric radiant heating panels 1 to activate a second working state, i.e., the electric radiant heating panels 1 operate at high temperature. The electric radiant heating panels 1 in other areas remain off or activate a first working state, i.e., the electric radiant heating panels 1 operate at low temperature. The factory's heating system can maintain a low-load operation during normal times, operating at high temperature only in areas where people are present, ensuring the normal daily work of workers while avoiding heat waste in other areas of the factory.

[0039] How to use: By analyzing the factory's production process, the main activity areas of workers within the factory are initially determined. The intelligent recognition system is then set up, with cameras 2 installed above these areas to ensure coverage of the entire activity area. After a period of recognition, the cameras 2 transmit the collected image information to the control module 3. Computer vision recognition technology is used to identify frequently used areas, and electric radiant heating panels 1 are installed in these areas. The temperature controllers 4 of the electric radiant heating panels 1 are connected to the intelligent recognition system. The number of electric radiant heating panels 1 in frequently used areas is set according to an indoor temperature requirement of 15℃, while the number in other areas is set according to an indoor temperature requirement of 5℃.

[0040] Low temperature mode: When there is no personnel activity in the factory or when the factory is not in operation at night, the low temperature mode is turned on, and the electric heating radiant panel 1 operates at a low temperature to ensure that the factory reaches the duty temperature of 5℃.

[0041] Normal mode: When the factory is running, turn on some or all of the electric heating radiation panels 1 to ensure that the working temperature in the factory reaches 15℃.

[0042] Intelligent mode: When the factory is running, the camera 2 determines the location of the worker's activity area in real time and turns on the electric heating radiation panel 1 in the worker's area in real time, while other electric heating radiation panels 1 are turned on or off.

[0043] According to an embodiment of the present invention, in another aspect, a heating system is also provided, comprising: an intelligent identification system and an electric radiant panel 1, wherein the intelligent identification system is used to identify areas in the factory where personnel frequently move; multiple electric radiant panels 1 are installed in the factory, and the electric radiant panels 1 are communicatively connected to the intelligent identification system, wherein the number of electric radiant panels 1 arranged in areas where personnel frequently move is greater than the number of electric radiant panels 1 arranged in other areas.

[0044] In use, the intelligent identification system monitors and identifies data over a period of time, and summarizes the data using computer vision recognition technology to determine areas where personnel frequently move around. The number of electric radiant heating panels 1 arranged in these areas is greater than the number arranged in other areas. By rationally zoning and arranging the electric radiant heating panels 1, construction costs can be reduced. Based on the factory's operating status, the intelligent identification system controls the electric radiant heating panels 1 to switch between a first working state, a second working state, and a closed state, enabling the factory's heating system to operate at a low load daily, reducing heat waste and lowering operating costs. The heating system provided in this embodiment solves the problem of high construction and operating costs in existing technologies using electric radiant heating panels 1 for factory heating.

The intelligent identification system controls the temperature and operating status of the electric heating radiant panel 1 through the thermostat 4. Alternatively, as an alternative real-time method, the thermostat 4 can be omitted, and the intelligent identification system directly controls the opening and closing of the electric heating radiant panel 1.

[0046] In one embodiment, the system further includes a power supply mechanism electrically connected to the intelligent identification system and the electrothermal radiant panel 1. The power supply mechanism includes a photovoltaic module 5 and an energy storage device 6. The photovoltaic module 5 is installed on the roof of the factory building; the energy storage device 6 is electrically connected to the photovoltaic module 5, the electrothermal radiant panel 1, and the intelligent identification system. The photovoltaic module 5 is configured as a distributed photovoltaic system on the factory roof, converting solar energy into electrical energy, which is stored in the energy storage device 6 to provide power to the electrothermal radiant panel 1, achieving direct green electricity supply for the heating system, thus saving energy and protecting the environment. Alternatively, as an alternative implementation, the power supply mechanism can also be configured as a diesel generator, a wind power generation system, or other power supply methods such as municipal power grid.

[0047] Specifically, a distribution box 7 is provided, and the energy storage device 6 is connected to the electrothermal radiation plate 1 through the distribution box 7.

[0048] In one embodiment, the electric radiant heating panel 1 is suspended from the wall and / or roof of the factory building. Suspending the electric radiant heating panel 1 from the wall or roof reduces the space occupied on the factory floor while ensuring heating efficiency.
