Description

Technical Field

[0001] This invention relates to the field of smart pigsty technology, and in particular to methods and systems for pigsty environmental control and end-of-pipe gas treatment. Background Technology

[0002] Currently, most large-scale pig farms are closed, high-density operations. If the air entering the pigsty is not filtered, pathogens from the outside world can adhere to aerosols and enter the pigsty, increasing the risk of pathogen transmission. The temperature, humidity, and gas concentration in the pigsty greatly affect the pigs' living environment; regulating the pigsty environment is one of the keys to ensuring the healthy growth of pigs. High odor concentrations in the exhaust gases from the pigsty, if left untreated or improperly treated, can affect the health of farm workers and damage the surrounding ecosystem. While air filtration equipment, environmental control systems, and gas treatment systems are widely used in pigsties, their control components operate independently, failing to achieve optimal performance. Summary of the Invention

[0003] The purpose of this invention is to at least address one of the shortcomings of the prior art by providing a method and system for controlling the environment of pig houses and treating end-point gases.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Specifically, methods for controlling the environment and treating end-point gases in pigsties are proposed, including the following:

[0006] Air from outside the pigsty enters the air filtration chamber through the pressure difference between the air filtration chamber and the outside air, and is filtered by the air filtration chamber to obtain filtered air;

[0007] The filtered air enters the pigsty through the wet curtain and the air inlet window that is connected with it, and produces exhaust gas after being processed by the pigs in the pigsty.

[0008] The generated waste gas is drawn out by a fan to the deodorization chamber, where it is treated by a filter wall before being discharged.

[0009] During this period, the air pressure inside the air filter is detected based on the reading of the first air pressure sensor, and an alarm is triggered based on the detection results. An alarm is also triggered based on the temperature and humidity information monitored by the temperature and humidity sensors inside the pigsty. An alarm is triggered based on the readings of the first and second gas sensors. An alarm is triggered based on the readings of the first and second wind speed sensors. The air pressure of the filter wall is detected based on the reading of the second air pressure sensor, and an alarm is triggered based on the detection results. An alarm is also triggered based on the reading of the particle sensor.

[0010] Furthermore, specifically, the air pressure inside the air filter is detected based on the reading of the first air pressure sensor, and an alarm is issued based on the detection results, including:

[0011] If the reading of the first air pressure sensor is greater than the first air pressure threshold, it indicates that the air filter is blocked, and a warning message is pushed to the IP address of the preset breeding personnel to inform them to replace or clean it.

[0012] Furthermore, specifically, the air pressure of the filter wall is detected based on the reading of the second air pressure sensor, and an alarm is issued based on the detection results, including:

[0013] If the reading of the second air pressure sensor is greater than the second air pressure threshold, it indicates that the filter wall is blocked. An early warning message is pushed to the IP address of the preset breeding personnel and they are informed to replace or flush the filter.

[0014] Furthermore, specifically, the deodorization chamber's treatment process for the exhaust gas includes,

[0015] The solution obtained by the nozzle from the collection tank and sprayed out passes through the filter media wall, where the solution forms a water film on the mesh inside the filter media wall.

[0016] The generated waste gas passes through the water film, where it merges with the water film. The water film reduces the corresponding gas components in the waste gas to obtain filtered gas.

[0017] The filtered gas condenses into liquid at the return plate and is collected and returned to the collection tank, completing the circulation of the nozzle solution.

[0018] Furthermore, specifically, alarms are triggered based on the readings of the first and second gas sensors, including:

[0019] First, the readings of the first gas sensor are acquired at regular intervals T within a certain time range to obtain multiple readings;

[0020] Analyze the changing trends of multiple readings to determine if there are any abnormal trends, and if so, issue an alarm for abnormal gas change trends.

[0021] Determine whether the reading of the first gas sensor exceeds the gas limit threshold within the specified time range. If it does, an alarm is triggered to indicate that there is a risk of gas abnormality in the pigsty.

[0022] Calculate the average difference between the readings of the first gas sensor and the second gas sensor at multiple simultaneous moments within the specified time range. If the average value is lower than the purification threshold, it indicates that the filter media wall is faulty and an alarm is triggered.

[0023] Furthermore, specifically, alarms are issued based on readings from the first and second wind speed sensors, including:

[0024] A first wind speed threshold and a second wind speed threshold are set respectively. When the reading of the first wind speed sensor is greater than the first wind speed threshold or the reading of the second wind speed sensor is greater than the second wind speed threshold, a wind speed abnormality alarm is issued.

[0025] Furthermore, specifically, alarms are triggered based on temperature and humidity information monitored by temperature and humidity sensors within the pigsty, including:

[0026] Set temperature and humidity thresholds. If the temperature exceeds the temperature threshold, a temperature anomaly alarm will be triggered. If the humidity exceeds the humidity threshold, a humidity anomaly alarm will be triggered.

[0027] Furthermore, specifically, it involves judging the changing trends of multiple readings and determining whether there are any abnormal trends, including...

[0028] Assume a certain time range is (t, t+NT), and a total of N samples are taken, where N is a positive integer and t is an arbitrary starting time;

[0029] A coordinate system is established with time as the horizontal axis, the reading of the first gas sensor as the vertical axis, and (t, 0) as the origin, resulting in a two-dimensional coordinate system with N discrete points.

[0030] A fitted curve is obtained by fitting N discrete points using a fitting algorithm.

[0031] Calculate the shortest distance from each of the N discrete points to the fitted curve, and find the number P of points whose shortest distance is greater than a set threshold.

[0032] Determine if the quantity P is greater than the quantity threshold; if so, determine if there is an abnormal trend.

[0033] This invention also proposes a pigsty environmental control and terminal gas treatment system, comprising: arranged along the gas flow direction,

[0034] Air filtration chambers, including those arranged along the gas flow direction,

[0035] Protective netting, used to prevent mosquitoes and rats from entering the pigsty.

[0036] An air filter, used to remove large particulate pathogens exceeding a diameter threshold from the air, is equipped with a first air pressure sensor. This sensor detects the air pressure inside the air filter and issues an alarm based on the detected pressure.

[0037] A particle sensor is used to detect the concentration of particles exceeding the diameter threshold in the gas filtered by the air filter, and to determine whether the air filter is faulty based on this concentration.

[0038] Pigsties, including those arranged along the direction of gas flow,

[0039] The system includes an evaporative cooling pad and a corresponding air inlet window, with either the evaporative cooling pad or the air inlet window open simultaneously. The evaporative cooling pad cools the air entering the pigsty, while the air inlet window allows the air to flow into the pigsty.

[0040] A first wind speed sensor and a temperature and humidity sensor are used. The first wind speed sensor is used to detect the airflow velocity after passing through the evaporative cooling pad, and the temperature and humidity sensor is used to detect the temperature and humidity information inside the pigsty.

[0041] The first gas sensor is used to detect the gas concentration value of a preset gas in the pigsty.

[0042] A blower is used to extract gas from inside the pigsty.

[0043] Deodorization chambers, including those arranged along the gas flow direction,

[0044] The second wind speed sensor is used to detect the flow rate of the gas extracted by the fan.

[0045] A filter wall is used to purify the gas extracted by the fan. The filter wall is equipped with nozzles for spraying a solution onto it. The filter wall also has a second pressure sensor for detecting the pressure within the filter wall and issuing an alarm based on the detected pressure.

[0046] The return plate is used to collect the solution formed by the condensation of gas passing through the filter media wall into a collection tank for recycling.

[0047] The second gas sensor is used to detect the gas concentration value of the preset gas after purification by the filter wall, and to determine whether the discharged gas meets the preset emission standard, and to determine whether there is a fault in the filter wall.

[0048] The beneficial effects of this invention are as follows:

[0049] This invention proposes a method and system for pigsty environmental control and end-of-pigment gas treatment. First, the air entering the pigsty is filtered through an air filtration chamber. Then, the waste gas generated in the pigsty is treated through a deodorization chamber and finally discharged. The entire process adopts an appropriate control method based on the current use of pigsty environmental control equipment and end-of-pigment gas treatment equipment. The air filtration, environmental control, and gas treatment systems are linked together to achieve coordinated and automatic operation of the equipment. Real-time alarms are provided for abnormal parameters and equipment malfunctions, allowing farmers to understand environmental parameter information and equipment operation status in a timely manner.

[0054] The following will provide a clear and complete description of the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, solution, and effects of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The same reference numerals used throughout the accompanying drawings indicate the same or similar parts.

[0055] Reference Figure 1 as well as Figure 3 Example 1: This invention proposes a method for controlling the environment of pigsties and treating terminal gases, including the following:

[0056] Step 110: Air from outside the pigsty enters the air filtration chamber through the air pressure difference between the air filtration chamber and the outside air, and is filtered by the air filtration chamber to obtain filtered air;

[0057] Step 120: The filtered air enters the pigsty through the wet curtain 3 and the air inlet window 9 that works with it, and generates exhaust gas after being processed by the pigs in the pigsty.

[0058] Step 130: The generated waste gas is drawn out by the fan 10 to the deodorization chamber, treated by the filter wall 14, and then discharged.

[0059] During this period, the air pressure inside the air filter 2 is detected based on the reading of the first air pressure sensor 5, and an alarm is triggered based on the detection results. An alarm is also triggered based on the temperature and humidity information monitored by the temperature and humidity sensor 7 inside the pigsty. An alarm is triggered based on the readings of the first gas sensor 8 and the second gas sensor 16. An alarm is triggered based on the readings of the first wind speed sensor 6 and the second wind speed sensor 11. The air pressure inside the filter wall 14 is detected based on the reading of the second air pressure sensor 13, and an alarm is triggered based on the detection results. An alarm is also triggered based on the reading of the particle sensor 4.

[0060] In this embodiment, the ventilation process of the pigsty is as follows:

[0061] 1. All devices are turned on;

[0062] 2. Due to the pressure difference between the air filter chamber and the outside air, the air outside the pigsty automatically enters the air filter chamber and is filtered by air filter 2;

[0063] 3. The air filtered by air filter 2 enters the pigsty. There are two ways to do this: one is to open the roller shutter at the front end of the wet curtain 3 in summer, and the air enters the pigsty after being cooled by the wet curtain 3; the other is to close the roller shutter at the front end of the wet curtain 3 in spring, autumn and winter, and open the air inlet window 9 on the top of the pigsty, and the air enters the pigsty through the air inlet window 9. Alternatively, the ambient temperature can be monitored and an ambient temperature threshold can be set. When the threshold is reached, the wet curtain 3 channel is opened and the air inlet window 9 channel is closed. When the threshold is not reached, the wet curtain 3 channel is closed and the air inlet window 9 channel is opened.

[0064] 4. The gas entering the pigsty provides a comfortable living environment for the pigs. The exhaust gas generated in the pigsty is extracted by the fan 10 at the tail end. At the same time, fresh gas continuously flows in from the wet curtain 3 or the air inlet end of the pigsty.

[0065] 5. The gas drawn out by the blower 10 enters the deodorization chamber and is discharged after passing through the filter wall 14.

[0066] First, the air entering the pigsty is filtered through an air filtration chamber. Then, the exhaust gas generated in the pigsty is treated through a deodorization chamber before being discharged. The entire process adopts an appropriate control method based on the current use of pigsty environmental control equipment and end-point gas treatment equipment. The air filtration, environmental control, and gas treatment systems are linked together to achieve coordinated and automatic operation of the equipment. Real-time alarms are issued for abnormal parameters and equipment malfunctions, so that farmers can understand environmental parameter information and equipment operation status in a timely manner.

[0067] In a preferred embodiment of the present invention, specifically, the air pressure inside the air filter 2 is detected based on the reading of the first air pressure sensor 5, and an alarm is issued based on the detection results, including:

[0068] If the reading of the first air pressure sensor 5 is greater than the first air pressure threshold, it indicates that the air filter 2 is blocked, and a warning message is pushed to the IP address of the preset breeding personnel to inform them to replace or clean it.

[0069] In this preferred embodiment, an anomaly judgment of the air filter 2 is made based on the first air pressure sensor 5. When the air pressure sensor 1 in the air filter chamber detects that the air pressure in the chamber is high and the particle sensor 4 detects that the concentration of large-diameter dust particles in the gas is within the normal range (≤5%), it can be determined that the air filter 2 is blocked. The system will issue a warning message to remind the breeding personnel to replace or clean it.

[0070] In a preferred embodiment of the present invention, specifically, the air pressure of the filter wall 14 is detected based on the reading of the second air pressure sensor 13, and an alarm is triggered based on the detection results, including:

[0071] If the reading of the second air pressure sensor 13 is greater than the second air pressure threshold, it indicates that the filter wall 14 is blocked. An early warning message is pushed to the IP address of the preset breeding personnel and they are informed to replace or flush the filter.

[0072] In this preferred embodiment, an abnormality detection method for the filter wall 14 is provided. The air pressure sensor 2 detects the air pressure at the end of the filter wall 14 in real time. If the air pressure value is large, the system issues an early warning message to remind the aquaculture personnel to check whether the filter wall 14 is blocked. If it is blocked, the filter wall 14 needs to be flushed or replaced.

[0073] In a preferred embodiment of the present invention, specifically, the deodorization chamber's treatment process for the waste gas includes,

[0074] The solution obtained and sprayed by the nozzle 12 through the collection tank passes through the filter wall 14, and the solution forms a water film on the mesh inside the filter wall 14;

[0075] The generated waste gas passes through the water film, where it merges with the water film. The water film reduces the corresponding gas components in the waste gas to obtain filtered gas.

[0076] The filtered gas condenses into liquid at the return plate 15, and is collected and returned to the collection tank through the return plate 15, completing the circulation of the solution in the nozzle 12.

[0077] In this preferred embodiment, by setting the filter wall 14 in the above manner, the solution used in the filter wall 14 can be recycled. In addition, different solutions can be configured to treat the exhaust gas discharged from the pigsty in a targeted manner. For example, if the spray solution is water, the harmful components in the gas, such as ammonia, will dissolve in the water, thereby reducing the odor concentration of the exhaust gas. If the spray solution is an acidic solution, the harmful components in the gas, such as ammonia, will react chemically with it, thereby reducing the odor concentration of the exhaust gas.

[0078] In a preferred embodiment of the present invention, specifically, an alarm is triggered based on the readings of the first gas sensor 8 and the second gas sensor 16, including...

[0079] First, the readings of the first gas sensor 8 are acquired at regular intervals T within a certain time range to obtain multiple readings;

[0080] Analyze the changing trends of multiple readings to determine if there are any abnormal trends. If so, issue an alarm for abnormal gas change trends. Here, it is considered that the reading of the first gas sensor 8 in the pigsty, that is, the monitored value, should be stable. If there are large fluctuations, it is highly likely that there is a problem with the pigs, and an alarm should be issued to remind and check.

[0081] Determine whether the reading of the first gas sensor 8 exceeds the gas limit threshold within the specified time range. If it does, determine that there is a risk of gas abnormality in the pigsty and issue an alarm.

[0082] Calculate the average value of the difference between the readings of the first gas sensor 8 and the second gas sensor at multiple simultaneous moments within the specified time range. If the average value is lower than the purification threshold, it indicates that the filter wall 14 is faulty and an alarm is triggered.

[0083] In this preferred embodiment, a method for judging the purification capacity of the filter wall 14 is provided, which can accurately determine whether the filter wall 14 can normally filter out harmful components in the gas. Based on this, it can be determined whether the filter wall 14 needs to be cleaned or replaced, or whether the solution concentration in the collection tank has reached saturation and the solution in the collection tank needs to be replaced.

[0084] In a preferred embodiment of the present invention, specifically, an alarm is triggered based on the readings of the first wind speed sensor 6 and the second wind speed sensor 11, including:

[0085] A first wind speed threshold and a second wind speed threshold are set respectively. When the reading of the first wind speed sensor 6 is greater than the first wind speed threshold or the reading of the second wind speed sensor 11 is greater than the second wind speed threshold, a wind speed abnormality alarm is issued.

[0086] In this preferred embodiment, in order to monitor the airflow speed entering and exiting the pigsty and ensure stable airflow, two wind speed sensors and their corresponding thresholds are set up, and an alarm is triggered once an abnormality occurs.

[0087] In a preferred embodiment of the present invention, specifically, an alarm is triggered based on the temperature and humidity information monitored by the temperature and humidity sensor 7 within the pigsty, including:

[0088] Set temperature and humidity thresholds. If the temperature exceeds the temperature threshold, a temperature anomaly alarm will be triggered. If the humidity exceeds the humidity threshold, a humidity anomaly alarm will be triggered.

[0089] In a preferred embodiment of the present invention, specifically, determining the changing trend of multiple readings and determining whether there is an abnormal changing trend includes...

[0090] Assume a certain time range is (t, t+NT), and a total of N samples are taken, where N is a positive integer and t is an arbitrary starting time;

[0091] A coordinate system is established with time as the horizontal axis, the reading of the first gas sensor 8 as the vertical axis, and (t, 0) as the origin, resulting in a two-dimensional coordinate system with N discrete points.

[0092] A fitted curve is obtained by fitting N discrete points using a fitting algorithm.

[0093] Calculate the shortest distance from each of the N discrete points to the fitted curve, and find the number P of points whose shortest distance is greater than a set threshold.

[0094] Determine if the quantity P is greater than the quantity threshold; if so, determine if there is an abnormal trend.

[0095] In this preferred embodiment, by judging the abnormal trend of the reading of the first gas sensor 8 through the above method, it is possible to accurately determine that there is an abnormal trend of the reading of the first gas sensor 8.

The return plate is used to collect the solution formed by the condensation of gas passing through the filter media wall into a collection tank for recycling. The second gas sensor is used to detect the gas concentration value of the preset gas after purification by the filter wall, and to determine whether the discharged gas meets the preset emission standard, and to determine whether there is a fault in the filter wall based on this. Specifically, an alarm is triggered based on the readings of the first gas sensor and the second gas sensor, including: First, the readings of the first gas sensor are acquired at regular intervals T within a certain time range to obtain multiple readings; Analyze the changing trends of multiple readings to determine if there are any abnormal trends, and if so, issue an alarm for abnormal gas trend. Determine whether the reading of the first gas sensor exceeds the gas limit threshold within the specified time range. If it does, an alarm is triggered to indicate that there is a risk of gas abnormality in the pigsty. Calculate the average of the differences between the readings of the first gas sensor and the second gas sensor at multiple simultaneous moments within the specified time range. If the average value is lower than the purification threshold, it indicates that there is a fault in the filter media wall and an alarm is triggered. Specifically, it involves judging the changing trends of multiple readings and determining whether there are any abnormal trends, including... Assume a certain time range is (t, t+NT), and a total of N samples are taken, where N is a positive integer and t is an arbitrary starting time; A coordinate system is established with time as the horizontal axis, the reading of the first gas sensor as the vertical axis, and (t, 0) as the origin, resulting in a two-dimensional coordinate system with N discrete points. A fitted curve is obtained by fitting N discrete points using a fitting algorithm. Calculate the shortest distance from each of the N discrete points to the fitted curve, and find the number P of points whose shortest distance is greater than a set threshold. Determine if the quantity P is greater than the quantity threshold; if so, determine if there is an abnormal trend.
