Therefore, energy conservation and emission reduction have become global concerns at present, ozone generated by energy conservation and emission reduction equipment is usually sucked into an engine, and the ozone and oxygen in the air promote fuel to be fully combusted.

However, in practice, when the temperature is relatively low, the amount of ozone generated increases, but the energy saving effect is not good.

Therefore, it is desirable to provide an energy saving and emission reduction device and a control system, which can accurately determine the temperature of an ozone generating device, thereby ensuring that the ozone generating device works within a preset temperature range and improving ozone generating efficiency.

Ozone generating devices are mostly used in the existing energy-saving and emission-reducing devices to generate ozone, combustion is promoted by the ozone, exhaust emission is reduced, and finally the purposes of energy conservation and emission reduction are achieved. However, the existing ozone generating device has lower ozone generating rate, thereby influencing the effects of energy conservation and emission reduction. CN104948354B discloses an energy saving and emission reduction device for an internal combustion engine, which solves the problem of pyrolysis of ozone by adding a temperature control device, but in practice, when the temperature is relatively low, the ozone generation amount increases, but the temperature decreases to reduce the number of negative ions generated and further to increase the ozone generation amount, so that the energy saving effect is not good.

In view of this, in some embodiments of the present disclosure, the fan operating parameter is determined by the target operating temperature of the ozone generating sheet and the temperature data of the temperature sensor, and the fan is controlled to operate based on the fan operating parameter, so that the ozone generating device operates within the preset temperature range, thereby improving the ozone generating efficiency.

As shown in fig. 1, the energy saving and emission reduction device 100 may include an ozone generating device 110, an exhaust gas detection device 120, and a control system 130.

In some embodiments, the energy saving and emission reduction device 100 may be used in various applications in the fuel saving and exhaust gas purification of automobiles. For example, the energy-saving and emission-reducing device 100 can generate ozone through the ozone generating device 110, so that the ozone is sucked into the fuel engine to promote combustion, and the catalytic combustion-supporting function is achieved, so that the fuel combustion becomes more sufficient, and the emission of harmful gases, particles and the like is greatly reduced.

Ozone generating device 110 refers to a device that can be used to produce ozone. The ozone generating device 110 may include various types, for example, an ultraviolet irradiation type ozone generating device, an electrolytic type ozone generating device, and the like. In some embodiments, ozone generating device 110 can include ozone generating sheet 111, fan 112, and temperature sensor 113.

The second air inlet channel can be used for sending cooled oxygen to the ozone generating sheet so as to adjust the operating temperature of the ozone generating sheet. For example, the second air intake passage may employ a metal duct. In some embodiments, the second air inlet channel can exchange heat with the ozone generating device, so that the temperature of the ozone generating sheet is reduced, and the ozone generating sheet works at a proper temperature. For example, the second air inlet channel can cool the oxygen and convey the cooled oxygen into the device, thereby cooling the ozone generating sheet.

In some embodiments, the fan may further include an air outlet channel, the fan drives the turbine to rotate through the main shaft, and air enters from the two air inlet channels under the action of negative pressure and is sent to the ozone generating sheet for ionization through the air outlet channel.

The temperature sensor 113 is a sensor for sensing a temperature and converting it into a usable output signal. In some embodiments, a temperature sensor may be located inside the ozone generating device for sensing the temperature of the ozone generating sheet. In some embodiments, the temperature sensor is electrically connected to the control system.

In some embodiments, the temperature sensor may also include a sensor or the like that obtains temperature data external to the ozone generator.

The exhaust gas detection device 120 is a device for acquiring exhaust gas data. For example, the exhaust gas detection device may be a device for detecting automobile exhaust gas (e.g., an exhaust gas analyzer, various sensors, etc.). The tail gas analyzer can detect and analyze the content of different component gases in the tail gas of the engine under different working conditions. In some embodiments, the exhaust gas detection device is electrically connected to the control system. For more on the exhaust data, see the relevant description in fig. 3.

The control system 130 refers to a system with computing power, such as a computer, an industrial personal computer, a computing cloud platform, and the like.

When the ozone generating sheet operates, the fan operating parameters are sent to the fan, and the fan is controlled to operate based on the fan operating parameters, wherein the fan operating parameters are determined based on the target operating temperature of the ozone generating sheet and the temperature data of the temperature sensor.

In some embodiments, the control system may send the determined fan operating parameters to the fan in real time as the ozone generating sheet is operating.

For more on the control system 130, reference may be made to the description in the embodiment described below in fig. 1.

In some embodiments, the energy conservation and emission reduction device 100 may further include a negative oxygen ion generator 410, an exhaust gas detection device 120, and a control system 130, as more fully described with reference to FIG. 4.

The fan operation parameter refers to a parameter related to the fan operation. For example, the fan operation parameters may include any one or combination of opening or closing of the electrically controlled valve of the air inlet channel, opening degrees of different electrically controlled valves, fan power, and the like.

In some embodiments, the control system may construct a first vector database, store the first feature vector in correspondence with the fan operation parameter, select a reference vector having a minimum distance from the current first feature vector, and use the fan operation parameter corresponding to the reference vector as the current fan operation parameter. The first feature vector may include a target operating temperature, temperature data of a temperature sensor, and the like.

The target operating temperature refers to an operating temperature of the ozone generating device that enables the ozone generating efficiency to reach the target generating efficiency. The target operating temperature may be a certain temperature value or a certain temperature range. The ozone concentration is related to the ozone generation rate, the ozone decomposition rate, and the like. The target operating temperature affects the ozonolysis rate. When the ozone generation rate is constant, the ozone concentration is only related to the ozone decomposition rate. The concentration of ozone (i.e., the ozone decomposition rate) needs to be maintained in an appropriate range to avoid excessive ozone concentration or excessive energy consumption. In some embodiments, ozone decomposition can be brought to an appropriate rate by maintaining the operating temperature of the ozone generating tablets at a target operating temperature.

In some embodiments, the control system may determine the target operating temperature via a first preset table. The first preset table may store therein the correspondence between each fuel type, environmental data, etc. and the target operating temperature. The first preset table may be constructed based on experience or historical data.

In some embodiments, the control system may determine the target operating temperature of the ozone generating tablets by vector database matching based on historical fuel data, including fuel type and degree of combustion of the fuel.

The historical fuel data refers to data relating to fuel during historical travel of the vehicle. For example, the historical fuel data may include a fuel type in the historical driving, a degree of combustion of the fuel, and the like. The degree of combustion of the fuel refers to the degree to which the vehicle burns a particular fuel. The degree of combustion may be expressed in a number of ways, such as numerical values, percentages, etc. The higher the value, the higher the degree of combustion representing the fuel. The concentration of ozone is inconvenient to directly measure, so that whether the fuel is fully combusted or not can be determined through the historical combustion degree, and the combustion degree can indirectly reflect whether the concentration of ozone is proper or not.

In some embodiments, the target operating temperature may be determined based on the second feature vector. For example, the processor calculates a vector distance between a second feature vector of the current vehicle and a historical second feature vector of a historical vehicle in the second vector database based on the second feature vector of the current vehicle, and selects a plurality of first reference feature vectors with vector distances smaller than a threshold value from the vector distances; selecting a plurality of second reference feature vectors with the historic combustion degree higher than a combustion threshold value from the plurality of first reference feature vectors based on the historic target operating temperature and the historic combustion degree corresponding to the plurality of first reference feature vectors; and carrying out weighted average on the historical target operating temperatures corresponding to the plurality of second reference feature vectors to obtain the target operating temperature. The weight is related to the vector distance, the greater the vector distance, the smaller the weight. The weight may also be related to the difference in the degree of combustion from the corresponding combustion threshold in some embodiments, the greater the difference the greater the weight. The combustion threshold may be a system-based or human-set value.

The second feature vector may include, among other things, fuel type, environmental data, vehicle speed, etc. Each of a plurality of historical second eigenvectors in the second vector database corresponds to a historical target operating temperature and historical combustion degree.

The environmental data refers to environmental data when the vehicle is traveling. For example, the environmental data may include data of temperature, humidity, and the like while the vehicle is running. In some embodiments, the environmental data may be obtained by a temperature sensor, a humidity sensor, or the like.

And establishing a second vector database according to the historical driving data of the historical vehicle, and searching in the second vector database, so that reasonable target operating temperature can be obtained relatively quickly.

According to some embodiments of the specification, through determining the operation parameters of the fan, the temperature is adjusted through wind speed, so that the ozone generating device is maintained at the target operation temperature, the ozone generating efficiency is improved, and the effects of energy conservation and emission reduction are achieved.

In some embodiments, the energy saving and emission reduction device may further include a wind speed sensor, and the control system may determine an operation condition of the second air intake channel based on wind sense data collected by the wind speed sensor; and sending the running condition to the ozone generating device so that the ozone generating device adjusts the second air inlet channel.

The wind speed sensor is a sensing device for measuring wind speed.

Wind sensing data refers to data collected by one or more historic time wind speed sensors regarding the flow of gas. For example, the wind sense data may include a gas flow velocity within the channel, i.e., wind speed, etc. In some embodiments, the wind sense data may include first wind sense data of the first air intake channel and/or second wind sense data of the second air intake channel, etc.

The operation condition of the second air inlet channel refers to the condition related to the operation of the second air inlet channel. For example, the operation condition of the second air inlet channel may include the operation time of the second air inlet channel, whether the second air inlet channel is opened, and the operation parameters of the second air inlet channel after the second air inlet channel is opened. For more details on whether the second air intake passage is open and the operating parameters of the second air intake passage after opening, reference may be made to the description of the embodiment shown in fig. 1 below.

In some embodiments, the control system may determine an operational condition of the second air intake channel based on wind sensing data collected by the wind speed sensor. For example, a first preset corresponding relationship exists between the wind sensing data and the running condition of the second air inlet channel. The control system may determine an operation condition of the second air intake channel based on the wind sense data and the first preset correspondence.

In some embodiments, the control system may determine whether the second air intake passage is open based on the target operating temperature, the temperature data, and the wind sensation data; and determining an operating parameter in response to the second air inlet channel opening.

In some embodiments, the control system may determine whether the second air intake passage is open based on whether the target operating temperature, the temperature data, and the wind sense data satisfy the first preset condition. The first preset condition may be a judgment condition related to the target operating temperature, the temperature data, and the wind sense data. For example, the first preset condition may be that the target operating temperature exceeds a first operating temperature threshold and/or that the temperature data exceeds a first temperature threshold, etc. The control system opens the second air intake channel based on the target operating temperature exceeding the first operating temperature threshold and/or the temperature data exceeding the first temperature threshold and/or the wind sense data exceeding the first wind sense threshold. The first operating temperature threshold, the first temperature threshold, and the first wind sensing threshold may be preset by the system or by human beings.

In some embodiments of the present disclosure, the operating parameters of the second air intake channel are determined based on the target temperature, the reading of the temperature sensor, and the wind sense data, so that the second air intake channel is adjusted according to the operating parameters to better meet the actual requirements, and meanwhile, the situation that the fan is frequently adjusted in the process of adjusting the operating parameters is avoided, damage to the fan is reduced, and the efficiency of ozone generation is further improved.

In some embodiments, the second air intake channel is open or not open for wind sensing data related to the first air intake channel.

In some embodiments, the control system may open the second air intake channel when it determines that the wind sensing data of the first air intake channel exceeds the wind sensing threshold. The second air inlet channel carries oxygen when cooling down, and when the wind speed of first air inlet channel exceeded the threshold value, indicate that the operating pressure of first air inlet channel is too big this moment, can open the supplementary oxygen that carries of second air inlet channel.

In some embodiments of the present disclosure, whether the second air inlet channel is opened is determined according to the wind sensing data of the first air inlet channel, so that the operation pressure of the first air inlet channel can be relieved, the second air inlet channel is opened to assist in conveying oxygen, and the transportation efficiency of the oxygen and the cooling effect on the ozone generating sheet are improved.

In some embodiments, the operating parameter of the second air intake channel may be a random one of a plurality of historical operating parameters of the second air intake channel.

In some embodiments of the present disclosure, the operation condition of the second air intake channel is determined based on the wind sensing data, and the second air intake channel is adjusted, so that the temperature adjusting effect of the energy saving and emission reduction device can be further improved, and the ozone generating device is maintained to operate at the preset temperature.

In some embodiments, the wind speed sensor comprises at least a first wind speed sensor and a second wind speed sensor, the first wind speed sensor is located in the first air inlet channel, and the second wind speed sensor is located in the second air inlet channel; in response to the second air intake channel being opened, the control system may determine an operating parameter of the second air intake channel based on the first wind sense data acquired by the first wind speed sensor and the second wind sense data acquired by the second wind speed sensor.

The first wind speed sensor is a device for measuring the wind speed in the first air intake channel. For example, the first wind speed sensor may measure the wind speed in the first air intake channel to obtain the first wind sense data. The first wind sense data may refer to wind sense data in a first air intake channel acquired by one or more historical time first wind speed sensors.

The second wind speed sensor is a device for measuring the wind speed in the second air intake channel. For example, the second wind speed sensor may measure the wind speed in the second air intake channel to obtain second wind sense data. The second wind sense data may refer to wind sense data in a second air intake channel acquired by one or more historical time second wind speed sensors.

For more details on the operating parameters of the second air intake channel, reference may be made to the description of the above-described embodiment in fig. 1.

In some embodiments, the control system may determine the operating parameters of the second air intake channel based on a second preset table. The second preset table may store a plurality of corresponding relations between the first wind sense data, the second wind sense data and the operation parameters of the second air inlet channel. In some embodiments, the second preset table may be constructed based on empirical or historical data.

In some embodiments of the present disclosure, actual operation data of the first air inlet channel and the second air inlet channel are comprehensively considered, and the operation parameters of the second air inlet channel are determined, so that the determined operation parameters of the second air inlet channel can be improved, which is beneficial to making the operation temperature of the ozone generating sheet be at the target operation temperature, and improving the ozone generating efficiency. The operating temperature of the ozone generating device is adjusted cooperatively based on the two air inlet channels, so that the times of adjusting the fan are reduced, and the service life of the fan can be prolonged.

In some embodiments, the operating parameters of the second air intake channel include a first parameter, a second parameter, etc., and in response to the second air intake channel being opened, the control system may determine the first parameter through a preset algorithm based on the target operating temperature, the temperature data, and the wind sensation data; based on the first parameter, a second parameter is determined.

The first parameter is a parameter related to wind speed. For example, the first parameter may include fan power, first target wind sense data, second target wind sense data, and the like. The first target wind sensing data may refer to a gas flow rate required to be reached by oxygen and the like conveyed in the first air inlet channel. The second target wind sensing data may refer to a gas flow rate that the second air intake channel is required to achieve to deliver oxygen.

For example, the control system may determine the second parameter based on a preset correspondence between the first parameter and the second parameter and the first parameter.

In some embodiments, the control system may determine the second parameter via a valve opening determination layer of the evaluation model, for more description, see the relevant description of fig. 2.

In some embodiments, the preset algorithm includes generating at least one candidate first parameter scheme; determining a prediction time based on a wind speed determination layer of an evaluation model, wherein the evaluation model is a machine learning model; determining a target first parameter scheme from candidate first parameter schemes of which the predicted time meets a time threshold; the first parameter is determined based on the target first parameter scheme.

Candidate first parameter schemes refer to schemes from which a first parameter needs to be determined. For example, the candidate first parameter scheme may include candidate fan power, first candidate wind sense data, and second candidate wind sense data.

In some embodiments, the candidate first parameter schedule may be generated based on a combustion condition of the vehicle. For example, the processor may screen one or more historical first parameter schemes corresponding to the same fuel type in the historical fuel data with a combustion degree greater than the threshold based on the fuel combustion condition of the vehicle, and determine the one or more historical first parameter schemes as candidate first parameter schemes.

When the second air inlet channel is determined to be opened, the first air inlet channel is determined to be in a closed state, and the first parameter and the second parameter determined at the moment are only related to the second air inlet channel; when the second air inlet channel is determined to be opened, the first air inlet channel is determined to be in an opened state, and then the first parameter and the second parameter determined at the moment are related to the first air inlet channel and the second air inlet channel (for example, first target wind sense data and the opening degree of a valve of the first air inlet channel). For a more description of the degree of opening of the first electrically controlled valve, reference may be made to the relevant description in fig. 2.

In some embodiments, the operating state of the vehicle may have an effect on the time the actual temperature is reduced to the target temperature. For example, if the current speed of the vehicle is too high, the heat generated by the vehicle operation is high, resulting in a high overall temperature near the engine of the vehicle, which affects the time required for the second air intake passage to reduce the actual temperature to the target temperature. In some embodiments, the operating state of the vehicle may be obtained by onboard sensors.

FIG. 3 is an exemplary flow chart for determining an adjusted target operating temperature according to some embodiments of the present description.

In some embodiments, the process 300 may be performed by a control system. As shown in fig. 3, the process 300 includes the steps of:

At step 310, an adjusted target operating temperature is determined.

The adjusted target operating temperature refers to the adjusted target operating temperature that is more suitable for the operation of the ozone generating device.

In some embodiments, the control system may determine the adjusted target operating temperature in a variety of ways. For example, the control system may determine the adjusted target operating temperature through a historical adjustment temperature record. For example, the control system may retrieve an adjustment record of the historical target operating temperature stored in the system, compare the similarities of the historical and current ambient temperatures, vehicle operating conditions, and the like, and use the historical adjusted target operating temperature having a similarity greater than the threshold as the current adjusted target operating temperature.

In some embodiments, the control system may obtain the exhaust data via the exhaust detection device while the ozone generating sheet is operating, adjust the target operating temperature based on the exhaust data, and determine the adjusted target operating temperature. For details of the exhaust gas detection device, reference may be made to the relevant description in fig. 1.

The exhaust gas data refers to data related to exhaust gas of a vehicle. The exhaust gas data may include the concentration of chemicals contained in the exhaust gas, for example, carbon monoxide Concentration (CO), nitrogen oxide concentration (NOx), hydrocarbon Concentration (HC), and the like.

Exhaust data may be obtained by a sensor. For example, the control system may acquire the concentrations of carbon monoxide, nitrogen oxides, hydrocarbons, and the like through a carbon monoxide sensor, a nitrogen oxide sensor, a hydrocarbon sensor, and the like built in the exhaust gas detection device.

In some embodiments, the exhaust data may be continuously obtained by the exhaust detection device while the ozone generating sheet is in operation.

In some embodiments, the control system may adjust the target operating temperature based on the exhaust data and determine the adjusted target operating temperature. In some embodiments, the exhaust data and the target operating temperature have a second preset correspondence, and the control system may adjust the target operating temperature based on the exhaust data according to the second preset correspondence.

According to some embodiments of the method, the target operating temperature is adjusted by analyzing the tail gas data, so that the setting of the target operating temperature is more reasonable, and the rationality and the efficiency of energy conservation are improved.

In some embodiments, the control system may determine a degree of combustion of the fuel based on the exhaust data over a preset period of time, adjust the target operating temperature based on the degree of combustion of the fuel, and determine the adjusted target operating temperature. For details of the degree of combustion of the fuel, reference may be made to the relevant description in fig. 1.

The preset time period refers to a period of time after the vehicle starts running. For example, 1 hour after the vehicle starts running may be taken as the preset period.

In some embodiments, the exhaust data may be processed to determine the degree of combustion of the fuel. For example, a concentration change map of the compounds contained in the exhaust gas may be drawn based on the exhaust gas data and the fuel consumption amount detected in the preset period of time. For example, a carbon monoxide Concentration (CO) concentration change map, a nitrogen oxide concentration (NOx) concentration change map, a Hydrocarbon Concentration (HC) concentration change map, and the like.

In each concentration variation graph, the preset time period is divided into a plurality of sub-time periods based on the preset concentration variation amplitude, the average concentration is calculated for each sub-time period, and the average concentration of the plurality of sub-time periods is weighted, so that the obtained concentration is used as the average concentration of the preset time period. The weight in the weight calculation is related to the length of the sub-period, and the longer the time, the greater the weight.

In some embodiments, the higher the average concentration of the compounds contained in the exhaust gas over the preset period of time, the lower the combustion degree of the fuel can be determined.

In some embodiments, the control system may adjust the target operating temperature based on the degree of combustion of the fuel, and determine the adjusted target operating temperature. For example, when the combustion degree of the fuel is low, the target operating temperature may be lowered, the adjusted target operating temperature may be set to a low value, the ozone decomposition rate is lowered, the ozone concentration becomes high, and the combustion of the fuel is made more sufficient.

In some embodiments, the combustion degree threshold is related to a vehicle temperature profile. The control system may preset a correspondence between the combustion degree threshold and the vehicle temperature distribution condition. The corresponding fuel burn degree thresholds are also different for different vehicle temperature profiles. For example, when the vehicle temperature distribution gap is large, the fuel combustion degree threshold is small.

The vehicle temperature distribution refers to a distribution of temperatures at different portions of the vehicle. The vehicle temperature profile is related to the ambient temperature and the heat released by the combustion of the fuel. For example, the higher the degree of combustion of the fuel (i.e., the closer to full combustion), the more heat the fuel releases, which can affect the temperature of various portions of the vehicle.

The combustion degree threshold may refer to a minimum value of the degree to which the vehicle burns fuel.

In some embodiments of the present description, the vehicle temperature distribution is correlated by the combustion degree threshold value, because the vehicle malfunction is easily caused when the difference in the vehicle temperature distribution is large. For example, the combustion degree threshold value needs to be determined under the condition of ensuring that the coolant temperature, the exhaust pipe temperature, and the like are normal. The risk of failure of the vehicle can be greatly reduced.

In some embodiments of the present disclosure, the combustion degree of the fuel is determined according to the exhaust data, and the target operating temperature is adjusted according to the combustion degree of the fuel, so that the determination of the target operating temperature is more accurate, the risk of vehicle failure can be reduced, and the safety and accuracy of the system are improved.

In some embodiments, the control system may predict the adjusted target operating temperature via a temperature prediction model based on the target operating temperature, the degree of combustion of the fuel, the degree of combustion threshold, the ambient temperature, the wind sense threshold, and the time threshold.

The temperature prediction model refers to a model that can be used to predict the adjusted target operating temperature. The temperature prediction model may be a machine learning model, such as a convolutional neural network model. The temperature prediction model may be a machine learning model. The inputs to the temperature prediction model may be a target operating temperature, a combustion level of the fuel, a combustion level threshold, an ambient temperature, wind sense data, and a time threshold. The output of the temperature prediction model may be the adjusted target operating temperature. Details regarding the target operating temperature, wind sense data, and time thresholds may be found in the relevant description of fig. 1. For details regarding the ambient temperature, see the relevant description in fig. 2.

In some embodiments, the temperature prediction model may be trained based on a plurality of second training samples with the identification. For example, a second training sample with an identification is input into the temperature prediction model, and parameters of the temperature prediction model are updated through training.

In some embodiments, the second training sample may be a sample target operating temperature, a sample fuel burn level, a sample burn level threshold, a sample ambient temperature, sample wind sense data, and a sample time threshold. The label corresponding to the second training sample may be the adjusted target operating temperature. In some embodiments, training may be performed by various methods based on the second training sample. For example, training may be based on a gradient descent method.

In some embodiments of the present disclosure, the temperature prediction model predicts the adjusted target operating temperature, and considers the wind sensing threshold and the time threshold, so that the risk of damaging the fan due to too low temperature is reduced, and the efficiency of adjusting the temperature and the accuracy of the model result are improved.

Step 320, the adjusted target operating temperature is sent to the ozone generating device to cause the ozone generating device to operate based on the adjusted target operating temperature.

The target operating temperature and the details of the ozone generating device can be seen in fig. 1 and its related content.

In some embodiments, the control system may communicate with the ozone generating device and send data of the target operating temperature to the ozone generating device.

In some embodiments of the present disclosure, the control system may determine the adjusted target operating temperature to cause the ozone generating device to operate based on the adjusted target operating temperature. The normal operation of the ozone generating device can be ensured, and the accuracy and the energy-saving capability of the device are improved.
