Description

Technical Field

[0001] This invention belongs to the field of environmental control technology, and relates to an environmental control system, particularly a radiation environmental control and dehumidification control system, method, electronic device and storage medium. Background Technology

[0002] Capillary radiant air conditioning systems are a new type of energy-saving and comfortable air conditioning that can replace conventional central air conditioning. These systems typically use water as the refrigerant, transferring heat through uniform and tightly packed capillary tubes. The required chilled water supply temperature for this system is only about 14-19℃ in summer and 32-30℃ in winter. Compared to conventional water-cooled air conditioning systems, which require a supply water temperature of 7℃ in summer and 45-50℃ in winter, capillary radiant air conditioning systems are significantly more energy-efficient and require lower temperatures.

[0003] The main unit outputs 7°C chilled water, which is mixed once in a storage tank, stabilizing the temperature at 7°C ± 2°C. The water is then divided into two streams: one stream is pumped by a first pump to a dehumidifier for dehumidification, and the other stream is pumped by a second pump to a plate heat exchanger for mixing. The water is then heated to a constant temperature of 16 or 18°C ​​and supplied to the radiant cooling terminals for radiant cooling. When the ambient temperature changes, the dew point also fluctuates, while the outlet water temperature of the heating / cooling equipment remains constant at 16 or 18°C, making condensation a likely problem.

[0004] Capillary radiant air conditioning systems are highly sensitive to humidity. Poor humidity control can affect the normal operation of the entire system, and may even cause it to fail. In particular, during the rainy season in southern China, humidity can reach over 90%, making it difficult to select suitable fresh air dehumidification equipment in the system design, resulting in poor dehumidification performance and failure to achieve effective dehumidification.

[0005] In view of this, there is an urgent need to design a new environmental control system in order to overcome at least some of the aforementioned shortcomings of existing environmental control systems. Summary of the Invention

[0012] According to another aspect of the present invention, the following technical solution is adopted: a control method for the above-mentioned radiation environment regulation and dehumidification control system, the control method comprising: The main control module acquires ambient humidity and temperature data through sensor components, and controls the operation of the cold and heat source device, air handling device and refrigeration auxiliary device based on the ambient humidity and temperature data; When the ambient humidity is greater than the set threshold, the main control module controls the system to be in dehumidification mode, and the main control module controls the cold and heat source device and the refrigeration auxiliary device to output water at the set temperature to the air handling device for dehumidification.

The main control module controls the cold and heat source device to output water at the set temperature for radiant cooling of the terminal capillary network, and at the same time controls the cooling auxiliary device to output water at the set temperature for auxiliary cooling of the air handling device.

[0013] In one embodiment of the present invention, when the ambient humidity is greater than a set threshold, the cold and heat source device is controlled to output water at a temperature of 5-9°C to supply the air handling device for dehumidification, while the water path to each capillary network is closed; the main control module also controls the refrigeration auxiliary device to assist the cold and heat source device in dehumidification, and the main control module controls the refrigeration auxiliary device to output water at a temperature of 5-9°C to supply the air handling device for dehumidification. When the ambient temperature is higher than the target temperature, the dynamic dew point temperature is calculated based on the temperature and humidity data detected by the sensor components. The cold and heat source device is controlled to output a dynamic water temperature higher than the dew point temperature set threshold for radiative cooling of the terminal capillary network, while the water path to the air handling unit is closed. The main control module also shuts down the cooling auxiliary device at the same time.

[0014] As one embodiment of the present invention, the control method further includes: The dew point temperature acquisition module compensates the dew point temperature data in real time based on the real-time data sensed by the sensor components, and obtains the compensated dew point temperature data. The main control module controls the outlet water temperature of the cold and heat source device based on the compensated dew point temperature data obtained by the dew point temperature acquisition module.

[0015] As one embodiment of the present invention, the control method further includes a dew point temperature prediction mathematical model construction step, which includes: preprocessing the data in a set training dataset; extracting features from the preprocessed data to extract key features; then combining, statistically analyzing, and grouping the extracted key features, and standardizing and normalizing the key features to form a key feature combination; the key feature combination includes temperature data obtained by each first temperature sensing unit, temperature data obtained by each second temperature sensing unit, temperature data obtained by each third temperature sensing unit, humidity data obtained by each humidity sensing unit, pressure data obtained by each pressure sensing unit, carbon dioxide concentration data obtained by each carbon dioxide sensing unit, location data of each sensing unit, building space data, layout data of each capillary network, personnel density data and distribution data, and dew point temperature data; and constructing a dew point temperature prediction mathematical model based on the formed key feature combination.

[0016] According to another aspect of the present invention, the following technical solution is adopted: an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above method.

[0017] According to another aspect of the present invention, the following technical solution is adopted: a storage medium storing computer program instructions thereon, which, when executed by a processor, implement the steps of the above-described method.

[0018] The beneficial effects of this invention are as follows: The radiation environment regulation and dehumidification control system, method, electronic equipment, and storage medium proposed in this invention can solve dehumidification and radiant cooling functions using a single dynamic variable water temperature device and a single water pump, without a storage tank or manifold, effectively achieving dehumidification in high humidity scenarios and applicable to various situations. At the same time, this invention can reduce equipment costs, reduce equipment footprint, simplify the system, reduce failure rate, simplify construction, facilitate maintenance, and is more energy-efficient.

[0019] This invention can calculate the dew point temperature based on indoor temperature and humidity and supply it to the end of the capillary tube for radiative cooling; when the temperature and humidity of the area are harsh, the auxiliary cold source can meet the system's design requirements even in harsh environments; it can automatically switch to cooling or dehumidification mode according to environmental parameters, greatly increasing the types of applicable environmental scenarios.

[0020] This invention saves 65% more energy than air conditioning, and its cooling and heating capacity is only 35% of that of air conditioning. Air conditioning blows out dry, biting cold air, which can easily cause "air conditioning sickness." This invention's system uses radiant cooling, so there is no wind, the temperature is cool, there is no noise because there is no air conditioner fan, the humidity can be set arbitrarily between 55% and 65%, and the fresh air ensures that the area is full of oxygen and clean, with built-in sterilization to remove formaldehyde, various odors, and carbon dioxide.

[0021] The cold source air handling device of this invention, based on the aforementioned coordinated temperature control of radiant terminals, constructs an integrated control logic of dynamic dew point compensation and multi-terminal linkage adjustment. It collects micro-environmental parameters of various indoor areas in real time through a built-in temperature and humidity sensor array, and combines fuzzy algorithms with PID control based on the differences in thermal response characteristics between ground and ceiling / wall radiant terminals.

[0022] In one application scenario of this invention, when the inlet water temperature of the ground coil reaches a set threshold, the system automatically triggers a pre-compensation program. By fine-tuning the inlet water flow rate and temperature gradient, the ground temperature is brought into a stable range first. After the ground temperature fluctuation is controlled within ±0.5℃, the adjustment mechanism of the top / wall end is gradually activated. At this time, the indoor reference dew point is calculated based on the stabilized ground temperature data, and the operating parameters of the top / wall are corrected through a secondary compensation algorithm to ensure that the dew point temperature deviation of each radiant surface does not exceed 1℃. This phased and progressive control strategy not only solves the dew point runaway problem caused by asynchronous temperature response of multiple terminals in traditional parallel systems, but also enables the system to maintain stable operation under different building orientations and differences in thermal inertia of the building envelope through adaptive optimization at the algorithm level.

[0030] The steps described in the various embodiments in the specification are for illustrative purposes only, and the implementation of this application is not limited by the order of the steps.

[0031] The term "connection" in the specification includes both direct and indirect connections, such as connections made through active devices, passive devices, or electrical conduction media; it may also include connections made by other active or passive devices that are known to those skilled in the art and can achieve the same or similar functional purpose, such as connections made through circuits or components such as switches or follower circuits.

[0032] This invention discloses a radiation environment regulation and dehumidification control system, which includes: a cold and heat source device 1, an air handling device 2, a refrigeration auxiliary device 3, at least one capillary network, a sensor assembly 7, and a main control module 8; in one embodiment, the at least one capillary network includes a first capillary network 5 and a second capillary network 6.

[0033] The main control module 8 is connected to the sensor assembly 7, the cold and heat source device 1, the air handling device 2, and the refrigeration auxiliary device 3 respectively; the cold and heat source device 1 and the refrigeration auxiliary device 3 are respectively connected to the air handling device 2; the cold and heat source device 1 and the refrigeration auxiliary device 3 are respectively connected to each capillary network.

[0034] The main control module 8 acquires ambient humidity and temperature data through the sensor component 7, and controls the operation of the cold and heat source device 1, the air handling device 2, and the refrigeration auxiliary device 3 based on the ambient humidity and temperature data.

[0035] When the ambient humidity is greater than the set threshold, the main control module controls the system to be in dehumidification mode, and the main control module controls the cold and heat source device and the refrigeration auxiliary device to output water at the set temperature to the air handling device for dehumidification. When the ambient temperature is higher than the set threshold, the main control module controls the system to be in radiant cooling mode. The main control module controls the cold and heat source device to output water at the set temperature for radiant cooling of the terminal capillary network, and at the same time controls the cooling auxiliary device to output water at the set temperature for auxiliary cooling of the air handling device.

[0036] In one application scenario of the present invention, when the ambient humidity is greater than a set threshold, the main control module 8 controls the cold and heat source device 1 to output water at a temperature of 5~9℃ (e.g., 5℃, 7℃, 9℃) to the air handling device 2 for dehumidification, while simultaneously shutting off the water paths to each capillary network; the main control module also controls the refrigeration auxiliary device 3 to assist the cold and heat source device 1 in dehumidification, and the main control module 8 controls the refrigeration auxiliary device 3 to output water at a temperature of 5~9℃ to the air handling device 2 for dehumidification.

[0037] When the ambient temperature is higher than the target temperature, the main control module 8 calculates the dynamic dew point temperature based on the temperature and humidity data detected by the sensor component 7, and controls the cold and heat source device 1 to output a dynamic water temperature higher than the dew point temperature set threshold (e.g., slightly higher than the dew point temperature, such as 1~3℃ higher) for radiant cooling of the terminal capillary network, while simultaneously closing the water path to the air handling unit 2; the main control module 8 also controls the cooling auxiliary device 3 to assist the cold and heat source device 1 in cooling, and the main control module 8 controls the cooling auxiliary device 3 to output a dynamic water temperature higher than the dew point temperature set threshold for auxiliary cooling of the air handling unit 2.

[0038] In one application scenario of this invention, the system control logic is as follows: the heat source device has only one water outlet connected to both a dehumidifier and electric ball valves in each zone (the electric ball valves connect to each terminal); when the system requires dehumidification, the heat source device outputs 7-degree water temperature to the dehumidifier for dehumidification, while simultaneously closing all terminal control valves for dehumidification. When radiant cooling is required, the heat source device directly outputs dynamically changing outlet water temperature to the zone electric ball valves, which then connect to the terminals for radiant cooling, while simultaneously closing the water path to the dehumidifier.

[0039] In one embodiment of the present invention, when the ambient humidity is greater than a set threshold, the main control module 8 controls the cold and heat source device 1 to output water at a temperature of 7°C to supply the dehumidification device 4 for dehumidification, while simultaneously shutting off the water path to each capillary network.

[0040] In one application scenario of this invention, the product is designed with fresh air and dehumidification functions manufactured in a proportional manner. For example, if the applicable humidity is 70% or 75%, the fresh air dehumidifier (i.e., air handling unit) can complete the task. However, in special scenarios, if the ambient humidity reaches 80%, 90%, or even 95%, the fresh air dehumidifier cannot achieve a good dehumidification function. In this case, it is necessary to activate the cooling auxiliary device 3 to complete the dehumidification function.

[0041] Furthermore, in cooling scenarios, if the indoor temperature rises rapidly (e.g., a large group of people suddenly gather for a meal in a hall), the terminal capillary network cannot meet the design requirements, exceeding its design range. In this case, the auxiliary cooling device 3 outputs a dynamic water temperature higher than the dew point temperature set threshold to assist the air handling unit 2 in cooling. The air handling unit and the terminal capillary network work together to cool the environment, effectively reducing the ambient temperature and fulfilling the design requirements.

[0042] In one embodiment of the present invention, the cold and heat source device 1 is used to provide a cold and heat source; the cold and heat source device 1 is connected to the air handling device 2 through a first input pipe and a first output pipe respectively; the air handling device 2 is used to handle the air in the designated building.

[0043] The cold and heat source device 1 is connected to the corresponding capillary network through the second input pipe and the second output pipe respectively; the first input pipe, the first output pipe, the second input pipe, and the second output pipe are each equipped with a valve.

[0044] The sensor assembly 7 includes at least one first temperature sensing unit, at least one second temperature sensing unit, at least one third temperature sensing unit, at least one humidity sensing unit, and at least one carbon dioxide sensing unit.

[0045] Each first temperature sensing unit is used to sense and set temperature data for a set area inside the building; each second temperature sensing unit is used to sense and set temperature data for a set area outside the building; each humidity sensing unit is used to sense and set humidity data for a set area inside the building; each carbon dioxide sensing unit is used to sense and set carbon dioxide concentration data for a set area inside the building.

[0046] In one embodiment of the present invention, the return water pipeline of the cold and heat source device is equipped with a check valve 17 or an electric ball valve (or a gas-operated electric valve, solenoid valve). When the return water pipeline is equipped with an electric valve, the electric valve is in the open state when the water pump is working. The steady-state radiation environment control system may also include a drain valve 18 to control the discharge of pollutants.

[0047] The main control module 8 is connected to the heat source device 1, the air handling device 2, the refrigeration auxiliary device 3, and the sensor assembly. The main control module controls the operation of the heat source device 1, the air handling device 2, the refrigeration auxiliary device 3, and the valves based on the data sensed by the sensor assembly.

[0048] Figure 2 This is a schematic diagram of the control section of a steady-state radiation environment control system according to an embodiment of the present invention; please refer to [link / reference]. Figure 2In one embodiment of the present invention, the main control module 8 includes a dew point temperature acquisition module 81. The dew point temperature acquisition module is used to compensate the dew point temperature data in real time based on the real-time data sensed by the sensor components, obtaining compensated dew point temperature data.

[0049] In one embodiment of the present invention, the sensor assembly further includes at least one pressure sensing unit, which is disposed in a designated area of ​​the capillary network to sense pressure data in the designated section of the capillary network. The main control module further includes a water flow disturbance noise removal module 82, which removes water flow disturbance noise based on the pressure data sensed by each pressure sensing unit using a Kalman filter algorithm. The dew point temperature acquisition module further compensates the dew point temperature data by combining the data after the water flow disturbance noise removal module has removed the noise, thereby obtaining compensated dew point temperature data.

[0050] The main control module 8 further includes a personnel density assessment module 83; the personnel density assessment module is used to assess the personnel density data and distribution data in the set building based on the data sensed by each carbon dioxide sensing unit using a dynamic fuzzy algorithm for carbon dioxide data.

[0051] The main control module includes a dew point temperature prediction mathematical model construction module 84, which is used to construct a dew point temperature prediction mathematical model. This module preprocesses the data in the set training dataset; extracts features from the preprocessed data to identify key features; then combines, statistically analyzes, and groups the extracted key features, standardizing and normalizing them to form a key feature combination. This key feature combination includes temperature data acquired by each first temperature sensing unit, temperature data acquired by each second temperature sensing unit, temperature data acquired by each third temperature sensing unit, humidity data acquired by each humidity sensing unit, pressure data acquired by each pressure sensing unit, carbon dioxide concentration data acquired by each carbon dioxide sensing unit, location data of each sensing unit, building space data, layout data of each capillary network, personnel density and distribution data, and dew point temperature data. The dew point temperature prediction mathematical model is constructed based on the formed key feature combination. The dew point temperature acquisition module inputs the temperature data acquired by each first temperature sensing unit, the temperature data acquired by each second temperature sensing unit, the temperature data acquired by each third temperature sensing unit, the humidity data acquired by each humidity sensing unit, the pressure data acquired by each pressure sensing unit, the carbon dioxide concentration data acquired by each carbon dioxide sensing unit, the location data of each sensing unit, the building space data, the layout data of each capillary network, the personnel density data, and the distribution data into the dew point temperature prediction mathematical model constructed by the dew point temperature prediction mathematical model construction module to obtain the dew point temperature data.

[0052] In one application scenario of the present invention, when the system is operating in cold radiation mode, the intelligent cold and heat source device automatically outputs dew point water temperature. The first valve 9 of the output pipeline of the air handling unit 2 is closed, the second valve 10 of the output pipeline of the refrigeration auxiliary device 3 is closed, and the third valve 11 of the output pipelines of the first capillary network 5 and the second capillary network 6 is open. The dew point water temperature output by the intelligent cold and heat source device simultaneously enters the ground capillary and the top capillary, and after being output, they converge and return to the main unit (intelligent cold and heat source device) through the third valve 11.

[0053] When the system is operating in automatic dehumidification mode, the intelligent cold and heat source equipment automatically outputs 7°C chilled water; the first valve 9 of the output pipeline of the air handling unit 2 is open, the second valve 10 of the output pipeline of the refrigeration auxiliary unit 3 is open, and the third valve 11 of the output pipelines of the first capillary network 5 and the second capillary network 6 is closed; the 7°C water output by the intelligent cold and heat source equipment passes through the air handling unit 2 and the first valve 13, through the refrigeration auxiliary unit 3 and the second valve 10, and then returns to the main unit (intelligent cold and heat source equipment).

[0054] When the system is operating in automatic fresh air mode, the intelligent cold and heat source equipment is not working, the first valve 9 of the output pipeline of the air handling unit 2 is closed, the second valve 10 of the output pipeline of the refrigeration auxiliary unit 3 is closed, and the third valve 11 of the output pipelines of the first capillary network 5 and the second capillary network 6 is closed; other equipment except for the fresh air handling equipment is not working.

[0055] When the system is operating in manual thermal radiation mode, the intelligent cold and heat source equipment is forced to set a higher temperature (e.g., 28~35℃); the output pipeline of the air handling unit 2 is set with the first valve 9 closed, the output pipeline of the refrigeration auxiliary unit 3 is set with the second valve 10 closed, and the output pipelines of the first capillary network 5 and the second capillary network 6 are set with the third valve 11 open; the outlet water temperature of the intelligent cold and heat source equipment is customized (28~35℃), and returns to the main unit through the third valve 11.

[0056] This invention further discloses a control method for the above-mentioned radiation environment regulation and dehumidification control system. Figure 3 This is a flowchart of a steady-state radiation environment control method according to an embodiment of the present invention; please refer to [link / reference]. Figure 3 The control method includes: The main control module acquires ambient humidity and temperature data through the sensor components, and controls the operation of the cold and heat source device, air handling device, and refrigeration auxiliary device based on the ambient humidity and temperature data.

[0057] When the ambient humidity is greater than the set threshold, the main control module controls the system to be in dehumidification mode, and the main control module controls the cold and heat source device and the refrigeration auxiliary device to output water at the set temperature to the air handling device for dehumidification. When the ambient temperature is higher than the set threshold, the main control module controls the system to be in radiant cooling mode. The main control module controls the cold and heat source device to output water at the set temperature for radiant cooling of the terminal capillary network, and at the same time controls the cooling auxiliary device to output water at the set temperature for auxiliary cooling of the air handling device.

[0058] In one embodiment of the present invention, the main control module acquires ambient humidity data and temperature data through sensor components, and controls the operation of the air handling device and the refrigeration auxiliary device according to the ambient humidity data and temperature data. When the ambient humidity exceeds a set threshold, the cold and heat source device outputs water at a temperature of 5-9°C to the air handling unit for dehumidification, while simultaneously shutting off the water supply to each capillary network. The main control module also controls the refrigeration auxiliary device to assist the cold and heat source device in dehumidification, and the main control module controls the refrigeration auxiliary device to output water at a temperature of 5-9°C to the air handling unit for dehumidification.

[0064] This invention also discloses an electronic device, Figure 4 This is a schematic diagram of the composition of an electronic device according to an embodiment of the present invention; please refer to [link / reference]. Figure 4 At the hardware level, the electronic device includes a memory, a processor, and at least one communication interface; the processor may be a microprocessor, and the memory may include main memory, such as random access memory (RAM) or non-volatile memory. Of course, the electronic device may also include other hardware as needed.

[0065] The processor, communication interface, and memory can be interconnected via an internal bus. The memory stores programs (including operating system programs and application programs); the programs may include program code, which may include computer operation instructions. The memory may include main memory and non-volatile memory, and provides instructions and data to the processor.

[0066] In one embodiment, the processor can read the corresponding program from non-volatile memory into memory and then run it; the processor can execute the program stored in memory and specifically perform the following operations (e.g. Figure 3 (as shown) The main control module acquires ambient humidity and temperature data through sensor components, and controls the operation of the cold and heat source device, air handling device and refrigeration auxiliary device based on the ambient humidity and temperature data; When the ambient humidity is greater than the set threshold, the main control module controls the system to be in dehumidification mode, and the main control module controls the cold and heat source device and the refrigeration auxiliary device to output water at the set temperature to the air handling device for dehumidification. When the ambient temperature is higher than the set threshold, the main control module controls the system to be in radiant cooling mode. The main control module controls the cold and heat source device to output water at the set temperature for radiant cooling of the terminal capillary network, and at the same time controls the cooling auxiliary device to output water at the set temperature for auxiliary cooling of the air handling device.

[0067] This invention further discloses a storage medium storing computer program instructions, which, when executed by a processor, implement the following steps of the method of this invention (e.g. Figure 3 (as shown) The main control module acquires ambient humidity and temperature data through sensor components, and controls the operation of the cold and heat source device, air handling device and refrigeration auxiliary device based on the ambient humidity and temperature data; When the ambient humidity is greater than the set threshold, the main control module controls the system to be in dehumidification mode, and the main control module controls the cold and heat source device and the refrigeration auxiliary device to output water at the set temperature to the air handling device for dehumidification. When the ambient temperature is higher than the set threshold, the main control module controls the system to be in radiant cooling mode. The main control module controls the cold and heat source device to output water at the set temperature for radiant cooling of the terminal capillary network, and at the same time controls the cooling auxiliary device to output water at the set temperature for auxiliary cooling of the air handling device.

[0068] In summary, the radiation environment regulation and dehumidification control system, method, electronic equipment, and storage medium proposed in this invention can solve dehumidification and radiant cooling functions using a single dynamic variable water temperature device and a single water pump, without a water storage tank or manifold, effectively achieving dehumidification in high humidity scenarios and applicable to various situations. At the same time, this invention can reduce equipment costs, reduce equipment footprint, simplify the system, reduce failure rate, simplify construction, facilitate maintenance, and is more energy-efficient.

[0069] This invention can calculate the dew point temperature based on indoor temperature and humidity and supply it to the end of the capillary tube for radiative cooling; when the temperature and humidity of the area are harsh, the auxiliary cold source can meet the system's design requirements even in harsh environments; it can automatically switch to cooling or dehumidification mode according to environmental parameters, greatly increasing the types of applicable environmental scenarios.

[0070] This invention saves 65% energy compared to air conditioning, while requiring only 35% of the cooling and heating capacity of an air conditioner. Air conditioners blow out dry, biting cold air, easily causing "air conditioning sickness." This invention's system uses radiant cooling, eliminating the feeling of wind and maintaining a cool temperature. Without an air conditioner's fan, there is no noise. Humidity can be set arbitrarily between 55% and 65%, and the fresh air ensures ample oxygen and cleanliness, with built-in sterilization to remove formaldehyde, various odors, and carbon dioxide.

[0071] The cold air handling device of this invention, based on the aforementioned coordinated temperature control of radiant terminals, constructs an integrated control logic of dynamic dew point compensation and multi-terminal linkage adjustment. It collects real-time micro-environmental parameters of various indoor areas through a built-in temperature and humidity sensor array, and combines fuzzy algorithms with PID control, taking into account the differences in thermal response characteristics between the ground and ceiling / wall radiant terminals. In one application scenario of this invention, when the inlet water temperature of the ground coil reaches a set threshold, the system automatically triggers a pre-compensation program. By fine-tuning the inlet water flow rate and temperature gradient, the ground temperature is brought into a stable range first. After the ground temperature fluctuation is controlled within ±0.5℃, the adjustment mechanism of the top / wall end is gradually activated. At this time, the indoor reference dew point is calculated based on the stabilized ground temperature data, and the operating parameters of the top / wall are corrected through a secondary compensation algorithm to ensure that the dew point temperature deviation of each radiant surface does not exceed 1℃. This phased and progressive control strategy not only solves the dew point runaway problem caused by asynchronous temperature response of multiple terminals in traditional parallel systems, but also enables the system to maintain stable operation under different building orientations and differences in thermal inertia of the building envelope through adaptive optimization at the algorithm level.

[0072] It should be noted that this application can be implemented in software and / or a combination of software and hardware; for example, it can be implemented using an application-specific integrated circuit (ASIC), a general-purpose computer, or any other similar hardware device.
