Description

Technical Field

[0001] The invention belongs to the technical field of deodorization and disinfection of breeding farms, and in particular relates to a precise drug dosing control system and method. Background Art

[0002] In recent years, breeding technology has developed rapidly, and more and more bungalow farms and building farms have been built. In order to ensure the healthy growth of livestock and poultry, deodorizers are added to solve the risk of odor caused by the emission of gas from pig houses to the external environment during ventilation. Specifically, the deodorizer is transported to the terminal through a delivery pipeline to solve the problem of virus elimination in the farm environment and air virus disinfection.

[0003] Take deodorization as an example. With the development of intensive farming, the number of pigs in the farms has gradually increased, the odor has become stronger, and the odor components have become more complex. Living in the odor for a long time can easily cause the pigs to be upset, eat less, become weaker, and even induce respiratory diseases and death.

[0004] Therefore, it is necessary to install a deodorization system outside the air outlet of the pig house. The deodorization system generally adopts the spray method, which includes a deodorization wall composed of a deodorization filter and a spray system. When the odor passes through, the liquid phase absorbs the gas phase, and the odor fully contacts the water dispersed through the filter. After dissolving in the water, it is chemically decomposed to achieve the purpose of deodorization and ammonia reduction.

[0005] Specifically, the deodorization system is installed behind the negative pressure fan exhaust port on the side wall of the pig house. When the system is running, the water in the pool / sink is sent to the spray pipe through the water pump, and the water is sprayed out through the nozzle along the exhaust direction of the fan to form water mist; at the same time, the pig house odor discharged by the fan passes horizontally through the deodorization layer, and the odor comes into contact with the evenly distributed water in it to form gas-liquid mixing. Part of the ammonia, hydrogen sulfide and dust in the odor is dissolved or washed by water, and the pig house odor is purified and discharged through the exhaust port of the deodorization system; the water that has been treated with the odor flows back to the pool / sink under the action of gravity and is pumped by the water pump, continuing the above process to form a cycle.

[0006] Therefore, in the prior art, whether it is deodorization or disinfection, disinfectants are added manually, which not only has an inaccurate amount of addition, but also cannot effectively detect the addition of additives. Summary of the invention

[0007] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a precise dosing control system and method to solve the above-mentioned problems.

[0008] To achieve the above object, one aspect of the present invention discloses a precise dosing control system, comprising:

[0017] Furthermore, the sensor module includes a wind speed sensor and a temperature and humidity sensor.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-4 As shown, one aspect of the present invention discloses a precise dosing control system, comprising:

[0036] The medicine supply and delivery control system includes a medicine supply and delivery device for storing and delivering medicines, the medicine supply and delivery device is provided with a medicine supply protection and warning device for protecting the safety of the medicine supply and delivery device, and also includes an electric control system electrically connected to the medicine supply and delivery device and the medicine supply protection and warning device respectively, and the outlet of the medicine supply and delivery device is connected to the precise dosing control system through a delivery pipeline 3;

[0037] The precise dosing control system is used for adaptive precise dosing of drugs and has an abnormal warning function. The electronic control system is electrically connected to the precise dosing control system;

[0038] The cloud control terminal is electrically connected to the electronic control systems of the drug supply and delivery control system and the precise drug adding control system respectively.

[0039] It should be noted that the cloud control terminal is the brain of the entire system. The data is uploaded to the cloud control terminal through the drug supply and delivery control system and the precise drug dosing control system. The cloud control terminal can achieve the corresponding big data center through calculation and learning. Through the accumulation of data volume, it can find the optimal range for precise drug dosing in the farm environment and control costs. At the same time, the cloud control terminal will also generate reports based on the corresponding data and send them to the management personnel, and push the system warnings to the corresponding personnel, so as to achieve visual management and monitoring throughout the process.

[0040] Compared with the prior art, the present application has the following effects: when working, the cloud control terminal controls the start-up of the drug supply and delivery device, and delivers the medicine to the precise drug dosing control system through the delivery pipe 3, wherein the drug supply protection warning device is used to detect the safety of the drug supply and delivery device, and feeds back the warning information to the cloud control terminal, and the cloud control terminal controls the operation of the drug supply and delivery device according to the signal, and controls the precise drug dosing control system to adaptively and precisely dosing according to the surrounding environment, thereby ensuring that the medicine is added to the terminal device more accurately, and the drug dosing process is fully automated, which greatly saves manpower.

[0041] Continuing with the above embodiment, more specifically, it also includes a medicine supply energy consumption monitoring device for monitoring the energy consumption of the medicine supply delivery device and electrically connected to the electronic control system. For example, the medicine supply energy consumption monitoring device can monitor power consumption and medicine usage, and by monitoring and reporting to the cloud control terminal, the breeding cost can be controlled and the waste of resources can be reduced.

[0042] Following the above embodiment, more specifically, Figure 4 As shown, the drug supply and delivery device includes a water pump 1, a stock liquid storage tank and a pressure tank 2. The stock liquid storage tank is provided with a liquid level transmitter for detecting the liquid level of the stock liquid storage tank. The water pump 1 delivers the medicine in the stock liquid storage tank to the pressure tank 2 through the delivery pipeline 3, and the pressure tank 2 delivers the medicine to the precise drug dosing control system through the delivery pipeline 3. Among them, the liquid level height in the stock liquid storage tank is monitored by the liquid level transmitter, the real-time liquid level change is monitored, and the insufficient liquid level warning and low liquid level protection are realized in combination with the electronic control system. The liquid level height information is fed back to the cloud control terminal in real time. The cloud control terminal issues a liquid level alarm message and controls the operation of the water pump 1. For example, when the liquid level height meets the requirements, the water pump 1 is started to deliver the medicine to the pressure tank 2.

[0043] It should be noted that, because the dosage at the end of the precise dosing control system is small and discontinuous, the design of the pressure tank 2 can ensure that the water pump 1 does not need to run all the time, which reduces the running time of the pump group, reduces energy consumption, and increases the life of the pump group.

[0044] Preferably, the water pump 1 can be a fluorine-lined drug supply pump to increase corrosion resistance, and the head and flow rate can be customized to meet the needs of the farm environment.

[0045] Following the above embodiment, more specifically, Figure 2As shown, the medicine supply protection warning device includes a pressure transmitter 4, an electric contact pressure gauge 5, a pressure relief valve 6 and an electric energy module sensor for detecting the power of the water pump 1, and the medicine supply energy consumption monitoring device includes an electromagnetic flowmeter 7 for detecting the flow of the medicine and an electric energy meter for detecting the amount of electricity; the pressure tank 2 is provided with an electric contact pressure gauge 5 and a pressure transmitter 4, the delivery pipeline 3 is provided with a pressure relief valve 6, and the electric energy module sensor is provided on the electric control system; the electric control system is electrically connected to the liquid level transmitter, the water pump 1, the pressure transmitter 4, the electric contact pressure gauge 5, the pressure relief valve 6, the electromagnetic flowmeter 7 and the electric energy meter respectively. Among them, through the design of pressure transmitter 4 and electric contact pressure gauge 5, real-time pressure changes are monitored, and over-pressure warning and abnormal pressure warning are realized in combination with the electronic control system; through the design of electromagnetic flowmeter 7, flow changes can be monitored in real time, and abnormal flow warning can be realized in combination with the electronic control system; through the process design of pressure relief valve 6, when the pressure exceeds the protection value, the conveying pipeline 3 is damaged and leaked, the pressure of the conveying pipeline 3 is quickly unloaded to reduce the risk of high-risk high-concentration sodium hypochlorite leakage and pipe burst; through the power module sensor to monitor the power change of water pump 1, when the power of water pump 1 changes, it is combined with other sensors to accurately judge whether water pump 1 has idling, blocking, aging and other phenomena. For example, when the power is 50% of the rated power, if the pressure continues to fail to reach the set value, it can be determined that water pump 1 is idling. In summary, through multiple monitoring and logical judgment, it is possible to realize abnormal monitoring of the system, improve the life protection of equipment, and reduce the investment in operating costs.

[0046] Following the above embodiment, more specifically, Figure 3 As shown, the precise dosing control system includes a solenoid valve arranged on the delivery pipeline 3 and used to control the start and stop of dosing, a pulse flowmeter for measuring the single dosing amount, and a sensor module for detecting the unit environmental index. The electronic control system is electrically connected to the sensor module, the solenoid valve, and the pulse flowmeter, respectively. Among them, through the design of the pulse flowmeter, the single dosing amount can be controlled and measured. When the solenoid valve is opened, the delivery pipeline 3 is connected, and when the solenoid valve is closed, the delivery pipeline 3 is closed. By making compensation settings through the electronic control system, the dosing amount control with an accuracy of 2ml can be achieved, and the environmental requirements of a small single dosing amount in the farm can be met.

[0047] The specific experimental data are as follows:

[0048]

[0049]

[0050] Continuing with the above embodiment, more specifically, the sensor module includes a wind speed sensor and a temperature and humidity sensor, so as to detect wind speed and temperature and humidity indicators in the environment.

[0051] Continuing with the above embodiment, more specifically, the electric control system is electrically connected to the circulation pump of the deodorization system and the breeding unit system, and is used to detect whether the circulation pump is operating normally and whether the breeding unit is empty. If the circulation pump is abnormal, it means that the terminal medication device is abnormal, the solenoid valve is closed, and the system determines that the precise dosing control system cannot add medication to the terminal. If the circle is empty, it means that there are no livestock in the breeding unit, so there is no need to add medication to the terminal.

[0052] It should be noted that the functions of the precision dosing control system include but are not limited to: ① Abnormal dosing protection: monitor the real-time dosing amount through the pulse flow meter. If the dosing amount is detected during the non-dosing period or the dosing amount is insufficient or excessive during the dosing period, early warning protection is performed; ② Adaptive dosing adjustment: monitor the real-time changes of unit ventilation volume and temperature and humidity through wind speed sensors and temperature and humidity sensors, and automatically adjust the dosing amount in combination with the electronic control system. For example, taking the pig house environment as an example, the ventilation volume in summer and winter is inconsistent. When the air volume changes greatly, the air volume increases suddenly. At this time, the wind volume that needs to be processed per unit time is too large. The volume is larger, so the dosage needs to be increased. At this time, the electronic control system will respond and adjust the single dosage (adjust the standard value under the corresponding air volume); ③ Disease purification warning: Taking the pig house as an example, we know through experiments that 10ppm sodium hypochlorite solution can achieve terminal air-outlet water washing disinfection and sterilization. When we dosing abnormalities, such as insufficient dosage, the system will issue a unit defense failure warning to avoid risks in advance; ④ Water washing circulation pump protection, through the power module in the electronic control system (such as the power module sensor), monitor the real-time power of the circulation pump, and when the power of the circulation pump is abnormal, early warning protection is performed.

[0053] Another aspect of the present application discloses a precise dosing control method, using the precise dosing control system as above, such as Figure 2 , Figure 3 As shown, including:

[0054] Step (1): Detect the liquid level of the stock liquid storage tank. If the liquid level is greater than the set liquid level value, execute the set dosing plan. Otherwise, push the liquid level protection alarm. When the liquid level in the stock liquid tank is greater than 30 cm, the set dosing plan can be executed. At the same time, when the liquid level in the stock liquid tank is greater than 30 cm and less than 50 cm, a low liquid level alarm will be pushed to remind the operator to replenish the agent to the stock liquid storage tank through the liquid delivery vehicle. When the liquid level in the stock liquid tank is less than or equal to 30 cm, a liquid level protection alarm is pushed, and the cloud control terminal controls to stop executing the set dosing plan.

[0055] Step (2): After starting to execute the set dosing scheme, use the pressure transmitter to detect the pressure of the pressure tank 2. If the pressure of the pressure tank 2 is greater than the set starting pressure, the water pump 1 is controlled to stop, indicating that it is not necessary to transport the medicine into the pressure tank 2. The pressure in the pressure tank 2 is sufficient to transport the medicine to the precise dosing control system. Otherwise, detect whether the pressure transmitter 4 is faulty (determined by judging the pressure transmitter value). If so, push a fault alarm to remind you to repair or replace the pressure transmitter 4. If not, detect whether the delivery pipeline 3 is damaged. Detecting the damage of the delivery pipeline 3 requires considering the pressure fluctuation of the unit during the non-dosing time period and the continuous flow of the electromagnetic flowmeter 7 when the unit solenoid valve is not opened; if the delivery pipeline 3 is damaged, open the pressure relief valve 6 and push the delivery pipeline 3 damage alarm. Otherwise, start the water pump 1;

[0056] Step (3): Detect whether the water pump 1 is faulty. If so, send a water pump 1 fault alarm. Otherwise, detect whether the pressure of the pressure tank 2 reaches the set stop pressure. If so, the water pump 1 stops. If not, detect whether the electric contact pressure gauge 5 reaches the high limit. If so, send a pressure transmitter 4 fault alarm. Further check whether the pressure transmitter 4 is faulty through the electric contact pressure gauge 5. If not, detect whether the start time of the water pump 1 is greater than the set start time. Specifically, detect whether the start time of the water pump 1 is greater than 1.5 times the set start time. If yes, send a water pump 1 operation timeout alarm. If not, start the water pump 1 and continue to execute the above steps. At the same time, detect whether the start interval of each water pump 1 is less than the set start interval. Specifically, detect whether the start interval of each water pump 1 is less than 1 / 2 of the set start interval. If yes, send a water pump 1 frequent start alarm. If not, start the water pump 1 and continue to execute the above steps until the pressure of the pressure tank 2 reaches the set stop pressure and the water pump 1 stops without fault.

[0057] Step (4): Set the dosing plan according to the detected unit environment index, execute this dosing, open the solenoid valve, and use the pulse flow meter to detect whether there is flow. If not, push the pulse flow meter fault alarm. Conversely, when the dosing amount reaches the set value, the solenoid valve is closed to complete this dosing. Among them, the unit environment index includes air volume and temperature and humidity. The wind speed sensor and temperature and humidity sensor monitor the real-time changes of the unit ventilation volume and temperature and humidity, and the dosing amount is automatically adjusted in combination with the electronic control system.

[0058] Continuing with the above embodiment, specifically, in step (3), the water pump 1 fault detection performs the following steps: detecting whether the thermal relay is tripped, if so, pushing the water pump 1 overload alarm and controlling the water pump 1 to stop; if not, further detecting whether the water pump 1 is running, if not, pushing the water pump 1 non-running alarm and controlling the water pump 1 to stop; if yes, reading the current power value, and by comparing the water pump 1 power value with the rated power, pushing the water pump 1 overload alarm or no-load alarm and controlling the water pump 1 to stop.

[0059] Among them, the judgment standard for water pump 1 overload alarm or no-load alarm is that when the current power of water pump 1 is greater than 2 times the rated power, water pump 1 overload alarm is pushed; when the current power of water pump 1 is less than 1 / 2 of the rated power, water pump 1 no-load alarm is pushed.

[0060] The above-mentioned water pump 1 fault detection is different from the prior art method of only using one-way pressure detection, and improves the accuracy of water pump 1 fault judgment. For example, if the power is 2 / 3 of the rated power, it is judged that the water pump 1 is aging or not running at full load.

[0061] Continuing with the above embodiment, more specifically, step (4) also includes: after the dosing scheme is set, it also includes detecting whether the unit is empty. If so, an empty alarm is pushed, and the cloud control terminal no longer executes the dosing scheme. An empty circle indicates that there are no livestock in the unit and no dosing is required. At the same time, it is detected whether the dosage is 0. If not, an alarm is pushed, and the cloud control terminal adjusts the dosage to 0. If it is not an empty circle, it is detected whether the circulation pump is operating normally. If so, the timing interval is reached and the dosing scheme is executed. If not, the circulation pump power is read, and the circulation pump power value is compared with the rated power. An overload or no-load alarm is pushed, and the circulation pump stops moving, and the dosing scheme is stopped at the same time.

[0062] Among them, the detection method for whether the above-mentioned circulation pump is normal can be that when the current power of the circulation pump is greater than 2 times the rated power, an overload alarm of the circulation pump is pushed; when the current power of the circulation pump is less than 1 / 2 of the rated power, a no-load alarm of the circulation pump is pushed.

[0063] Continuing with the above embodiment, more specifically, it also includes: when the timed interval arrives, executing the current drug addition, opening the solenoid valve, and using a pulse flow meter to detect whether there is flow. If not, a pulse flow meter fault alarm is pushed, the solenoid valve is closed, and the drug addition is stopped.

[0064] After the pulse flowmeter is repaired, add medicine again, and then use the compensation setting of the pulse flowmeter and the electronic control system to detect whether the added amount meets the standard. After the added amount meets the standard, close the solenoid valve to complete this dosing.

[0065] It should be noted that after the solenoid valve is closed, the pulse flowmeter continues to detect whether there is flow. If so, the solenoid valve fault alarm is pushed, the unit stops adding medicine, the pressure relief valve 6 in the medicine supply and delivery control system releases pressure, the water pump 1 stops delivering medicine to the pressure tank 2, and a reminder is given to replace the solenoid valve.

[0066] In summary, the effects of the present application include: 1. Accurate dosing of pathogenic killing agents in the farm environment is achieved through drug supply delivery + precise dosing + cloud control system, pathogen purification of the farm environment and zero diffusion of air outlet are achieved, environmental problems caused by the farm are solved, and the problem of odor diffusion in the air outlet is solved; 2. Small-particle deodorizing disinfectant addition is achieved with precise metering; 3.

When the dosage reaches the set value, the solenoid valve closes to complete the dosing.

9. A precise dosing control method according to claim 8, characterized in that: The step (1) further comprises: 1) detecting the liquid level of the stock liquid storage tank, and if the liquid level is greater than a set liquid level value, executing a set dosing plan, otherwise, sending a liquid level protection alarm; 2) detecting whether the pressure transmitter is faulty, and if so, sending a fault alarm, and if not, detecting whether the delivery pipeline is damaged; if the delivery pipeline is damaged, opening the pressure relief valve and sending a delivery pipeline damage alarm, and otherwise, starting the water pump; The step (2) further comprises: detecting whether the pressure of the pressure tank reaches the set stop pressure, if not, detecting whether the water pump start time is greater than the set start time; if yes, sending a water pump operation timeout alarm, if not, starting the water pump and continuing to perform the above steps, and detecting whether the water pump start interval is less than the set start interval, if yes, sending a water pump start frequent alarm, if not, starting the water pump and continuing to perform the above steps until the pressure of the pressure tank reaches the set stop pressure, so that the water pump stops without fault; The step (3) also includes: when the timed interval arrives, using a pulse flow meter to detect whether there is flow, if not, a pulse flow meter fault alarm is pushed, the solenoid valve is closed, and the dosing is stopped, and then the pulse flow meter is used to detect whether there is flow, if not, the current dosing is completed, if yes, a solenoid valve fault alarm is pushed, and the water pump is stopped; wherein the unit environment index includes air volume and temperature and humidity.

10. A precise dosing control method according to claim 9, characterized in that: After the dosing scheme is set in step (3), the step also includes detecting whether the unit is empty. If so, an empty alarm is pushed and the dosing scheme is no longer executed. If not, whether the circulation pump is operating normally is detected. If so, the timing interval is reached and the current dosing scheme is executed. If not, the circulation pump power is read, and the circulation pump power value is compared with the rated power to push the circulation pump overload or no-load alarm, and the circulation pump is stopped, and the dosing scheme is stopped.
