Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
Aiming at the defect that manual control is adopted for disinfection of livestock and poultry farms at present, the invention provides an automatic disinfection control system for livestock and poultry farms, which can comprehensively cover the whole process from purification and filtration of tap water to spraying of disinfectant in the farms, realizes the comprehensive automatic control of the purification of the tap water, the generation of the disinfectant and the spraying of the disinfectant, and solves the problems of high labor intensity, low working efficiency, poor disinfection effect and the like caused by manual control in the prior art.
As shown in fig. 1, the present invention provides a preferred embodiment, an automatic control system for livestock and poultry farm sterilization, comprising a PLC controller, a water treatment system, a raw water tank, an electrolysis system, a finished product tank and a spraying system. The raw water tank is used for storing raw water treated by the water treatment system, and the electrolysis system is used for electrolyzing the raw water in the raw water tank to generate sterilized water and storing the sterilized water in the finished product tank. The spraying system is used for spraying the disinfectant fluid in the finished product box to a corresponding area of a livestock and poultry farm for disinfection.
The water treatment system, the electrolysis system and the spraying system are respectively and electrically connected with the PLC. The PLC is used for carrying out centralized control on the water treatment system, the electrolysis system and the spraying system.
Further, the water treatment system is used for purified water produced by purifying and filtering tap water, and is referred to as raw water in the present embodiment, and hereinafter, referred to as raw water. The filtered raw water can be used as drinking water for livestock and poultry, and can also be used for generating sterilized water.
Generally, water in a farm is obtained through river water, well water, tap water and the like, the water quality is poor, the water generally contains more bacteria, viruses, other mud streams and other problems, unclean water is an important way for disease propagation, drinking water and water for livestock and poultry are effectively purified, sterilized and disinfected, and the morbidity of the livestock and poultry can be greatly reduced.
In addition, the generation of the sterilized water is generally performed by electrolyzing water by using an electrolytic cell, and when the water quality is poor, the electrolysis efficiency of the electrolytic cell is poor, and the service life of the electrolytic cell is affected. Therefore, before the sterilized water is generated, the water is firstly purified and sterilized, so that the electrolysis time of the electrolytic cell can be greatly prolonged, and the service life of the electrolytic cell is prolonged.
In order to intelligently control the on or off of the water treatment system, a first low liquid level sensor and a first high liquid level sensor are arranged in the raw water tank and used for detecting the capacity of raw water in the raw water tank.
Specifically, the method comprises the following steps: when the PLC detects that the data of a first low liquid level sensor in the raw water tank is lower than a first raw water level threshold value, the PLC control unit sends a water treatment starting signal to the water treatment system, the water treatment system is started to treat water and obtain raw water, and meanwhile, the filtered raw water is conveyed to the raw water tank to be stored.
When the PLC detects that the data of the first high liquid level sensor of the raw water tank is higher than the second raw water level threshold value, the PLC sends a water treatment stop signal to the water treatment system, and the water treatment device purification system is stopped from treating water.
Further, as shown in fig. 2, the water treatment system includes a first pump and a filtering device. One end of the first pump is connected with the filtering device and is used for conveying the filtered raw water to the raw water tank; the other end is connected with an external water source, such as a tap water pipeline, a river water source and the like, and is used for pumping the source water to the filtering device for filtering. Wherein, filter equipment generally adopts multistage filtration, for example adopt the cotton filtration of PP, ultrafiltration filter core filtration, RO mould filter core to filter etc. go on, become raw water with source water filtration, provide the water resource for the plant.
The PLC is electrically connected with the first pump and used for controlling the working state of the first pump. When the water capacity in the raw water tank is too low, the first pump is controlled by the PLC to start working, so that the first pump conveys source water to the filtering device for filtering, generated raw water is generated, and the generated raw water is conveyed to the raw water tank. When the water capacity in the raw water tank is excessive, the PLC controller controls the first pump to stop working.
In addition, in order to ensure that the filtered raw water meets the standard, the invention is also provided with a water flow detection device for detecting the water flow when the filtered raw water is conveyed to the raw water tank; setting a timer for timing; and a water quality detection device is arranged for detecting the water quality of the raw water conveyed into the raw water tank. Preferably, the water quality detection device comprises a water quality TDS detection device and a water hardness detection device, which are respectively used for detecting the water quality TDS and the water hardness for detection.
When the water treatment system starts to work: the PLC starts the timer and starts timing, and meanwhile receives data of the water flow detection device and calculates water flow. When the water flow is lower than a preset water flow threshold or the timing time exceeds a preset water treatment time threshold, the PLC starts a filter cleaning device to clean a filter element in the filter device, so that the scaling image filtering effect of the filter element is avoided; meanwhile, the filter element can be removed in time, so that the service life of the filter element can be prolonged.
Similarly, when the data of the water quality detection device exceed the preset water quality threshold value, for example, the water quality TDS exceeds the corresponding threshold value or the water hardness exceeds the corresponding threshold value, the PLC controller controls the first pump to stop working, and simultaneously sends out an alarm signal to remind a user to detect the related water treatment system device, so that the qualified water quality is ensured.
Further, an electrolysis system, as shown in fig. 3, is used to generate sterilized water for sterilization of a farm by electrolysis from raw water. The electrolysis system takes raw water from a raw water tank, mixes the raw water with salt to form salt water with a certain proportion, then electrolyzes the salt water to form sterilized water, and conveys the sterilized water to a finished product tank for storage. Specifically, as shown in fig. 2, the electrolysis system includes a second pump and an electrolysis cell. One end of the second pump is connected with the raw water tank, the other end of the second pump is connected with the electrolytic cell and used for removing raw water in the raw water tank and conveying the raw water into the electrolytic cell, and then the electrolytic cell carries out electrolysis on saline water in the electrolytic cell to generate disinfectant water and conveys the disinfectant water into the finished product tank for storage. The PLC is electrically connected with the second pump and used for controlling the working state of the second pump, so that the inner part of the raw water tank is pumped into the electrolytic bath.
In order to realize the intelligent control of the sterilized water, a second low liquid level sensor and a second high liquid level sensor are arranged in the finished product box and used for detecting the capacity of the sterilized water in the finished product box.
When the data of a second low liquid level sensor in the finished product tank is smaller than the first sterilized water level threshold value, the PLC controller controls a second pump to start to convey raw water into the electrolytic cell, then controls the electrolytic cell to be electrified to start electrolysis, and finally inputs the generated sterilized water into the finished product tank.
In addition, the electrolysis bath electrolyzes the brine during electrolysis, so the electrolysis system also comprises a salt adding pump. The salt adding pump is connected with the electrolytic cell and used for conveying high-concentration brine to the electrolytic cell and mixing the brine with raw water to form brine with a certain proportion.
Specifically, the method comprises the following steps: the PLC controller firstly starts the second pump to convey the raw water into the electrolytic cell, then starts the salt adding pump to convey the high-concentration salt water into the electrolytic cell, and then controls the electrolytic cell to be electrified to electrolyze the salt water with a certain proportion in the electrolytic cell to generate the sterilized water.
In addition, in this embodiment, when the second pump and the salt adding pump are started, it is further necessary to determine whether the current water flows into the electrolytic cell through the water flow switch, and if so, the electrolytic cell is controlled to be powered on to start electrolysis. Therefore, the arrangement mode of firstly judging whether the water flow circulates and then electrifying the electrolytic cell can avoid the problem that the electrolytic cell is damaged due to electrolysis when the electrolytic cell is in a water-free state.
And when the data of the second high liquid level sensor in the finished product tank is larger than the second sterilized water level threshold value, the PLC stops the work of the second pump and the work of the salt adding pump.
In addition, because the raw water in the electrolysis system is obtained from the raw water tank in the water treatment system, if the raw water tank has too little water to be used by the electrolysis system:
that is, when the data of the first low liquid level sensor in the raw water tank is smaller than the first raw water level threshold value, the PLC stops the work of the second pump and the salt adding pump; meanwhile, the PLC starts the first pump, and the source water is conveyed to the filtering device to be filtered to generate raw water and conveyed to the raw water tank.
Preferably, in order to ensure that the electrolyzed sterilizing water meets the requirements, the invention is also provided with a sterilizing water detection device for detecting the content of available chlorine in the sterilizing water in the finished product box.
When the content of the available chlorine in the disinfectant in the finished product box is smaller than the preset standard, the PLC controls the work of the electrolytic cell, for example, the electrolytic current of the electrolytic cell is increased until the content of the available chlorine in the disinfectant in the finished product box reaches the preset standard, and the electrolytic cell keeps the current electrolytic current. If the content of available chlorine in the sterilized water in the finished product box still does not reach the preset standard when the electrolytic current of the electrolytic cell is increased to the maximum limit value, the PLC control device triggers the alarm device to alarm to remind a user to check the water path fault.
On the contrary, when the content of available chlorine in the sterilized water in the finished product box is greater than the preset specification, the PLC controls the operation of the electrolytic cell, for example, the electrolytic current of the electrolytic cell is reduced until the content of available chlorine in the sterilized water in the finished product box reaches the preset specification, and the electrolytic cell keeps the current electrolytic current.
Further, a spraying system, as shown in fig. 5, is used to spray sterilizing water to the corresponding area for sterilization. As shown in FIG. 3, the spraying system in the embodiment adopts a plurality of spraying pipelines to realize the disinfection spraying of the farm. Specifically, the spraying system comprises a third pump, a multi-way spraying pipeline and a plurality of spray heads. Each spray head covers a certain area, all spray heads can cover all areas needing disinfection of a farm, and each spray head is provided with a corresponding electromagnetic valve. Each electromagnetic valve is electrically connected with the PLC and used for controlling the work of the corresponding spray head under the control of the PLC.

In order to ensure the time and the dosage of spraying, a spraying plan is formed according to the time of spraying required by each day, the spraying time of each spray head and the like and is stored in the system.
In the actual use process, the PLC controls the working states of the second pump and each electromagnetic valve according to the spray plan stored in the system, and further disinfection of the corresponding area of the farm is achieved. Because the spray control in the invention is controlled by the PLC, the problems of high labor intensity, uneven spraying and the like caused by manually holding the spray head to disinfect the corresponding area of the farm in the prior art are solved, and the disinfection efficiency and precision are greatly improved.

And when the accumulated timing time reaches the spraying time of the corresponding spray head, closing the electromagnetic valve so as to close the spray head.
Each spray head can be set with different spraying time according to different positions of the farm.
And when the spraying plan is finished, namely all areas needing to be disinfected in the farm are completely disinfected, the PLC controls the spraying system to stop spraying. Namely, the spray pump is controlled to stop working, and all the electromagnetic valves are closed so as to close all the spray heads.
Furthermore, when the data of the second low liquid level sensor in the finished product box is smaller than the water level threshold value of the first disinfectant, the PLC stops the work of the third pump, and simultaneously the electromagnetic valve is closed so as to close the spray head, thereby avoiding the damage to the spray pump caused by the empty pumping of the spray pipeline and protecting the spray system. In addition, in order to ensure the validity of the spraying time, the PLC controller stops the operation of the third pump, and when the electromagnetic valve is closed to close the spray heads, the current spraying cumulative timing time of each spray head needs to be recorded and stored in the system. When the PLC starts the third pump, the cumulative timing time of the spray of each spray head recorded in the system is compared with the spray time of the corresponding spray head in the spray plan, and when the cumulative timing time of the spray of each spray head is not consistent with the spray time of the corresponding spray head in the spray plan, the corresponding spray head is required to be opened again for spraying until the cumulative timing time of the spray of each spray head is consistent with the spray time of the corresponding spray head in the spray plan.

If the width exceeds 8 meters, the design is divided into 8 meters according to the method. The above design can be specifically set according to the size of the disinfection area of the actual livestock and poultry farm, and this embodiment is only an example for explanation.
Grouping is completed, each group of spray heads are connected into each group of electromagnetic valves through 4 PE pipes, and the work of the corresponding spray heads is controlled by controlling the on-off of the electromagnetic valves.
