Winter porch should pay attention to ventilation
Winter traps need to be warmed and kept in a relatively closed environment, which will greatly increase indoor carbon monoxide, carbon dioxide and respirable particulate matter. These harmful substances can lead to irritative damage and immunity of the pig's respiratory system, and increase the chance of respiratory diseases. Therefore, timely ventilation and disinfection of the housing are very important. However, the insulation and ventilation of pig farms in winter is a contradiction. To resolve these contradictions, it is necessary to pay attention to mastering scientific methods to benefit the health of pigs. Ventilation disinfection methods in winter housing include the following:
1, timely ventilation. When the temperature is relatively high at noon, the windows are ventilated for one hour. According to the survey, in the non-ventilated room, viral bacteria in the air can float for more than 30 hours. If the doors and windows are constantly open for air change, the dirty air can drift away at any time, and the room is also given plenty of light, and it is difficult for many viruses and germs to breed and reproduce.
2, regular disinfection. Disinfect the house regularly to keep pigs healthy. Disinfectant drugs should be used in rotation. The dosage should be determined according to the instructions. Do not increase the dose without authorization. Thorough cleaning must be done before disinfection. The ground should be treated like a layer of drizzle, not too wet (pig easy to diarrhea) or too dry (do not achieve the effect of disinfection). Each corner should be disinfected. When disinfecting, let the sprayer slowly drop the liquid above the pig and do not disinfect the pig.
3. Prevent icing. Disinfection outside winter homes can be difficult, especially when a disinfectant pool is set up to enter the area and the passage of a pig house. Ice formation may occur in winter. For this case, sprinkle some salt in the disinfectant so that it will not freeze. Also pay attention to the disinfectant inside the disinfecting tank to prevent the expired efficacy from decreasing or failing.
How do WiFi Camera Work ?
Monitoring cameras can also be installed without a network, but some functions cannot be used, such as remote monitoring. In order to make it easier for you to understand the knowledge related to the surveillance camera, I will use popular language to popularize science for you.
1: Camera introduction
Camera is an intelligent device that can capture and record video and monitor the environment in real time. It can not only record video, but also detect moving objects, sound, smoke, and even recognize faces.
The advantages of the camera are very obvious. It can help people better monitor the safety of their homes or offices, and help protect the safety of family members or office staff. In addition, it can also provide real-time video monitoring, provide more security guarantees, and help people better grasp the current security situation.
Among them, "intelligent camera" is a new technology in recent years, which can monitor the environment in real time and conduct intelligent identification. The intelligent camera adopts high-definition camera technology, which can clearly capture the on-site images within the monitoring range and conduct real-time monitoring. It can also analyze the captured pictures to identify the designated person or object, thus realizing intelligent monitoring.
In addition, the smart camera can also support remote monitoring. You can remotely view the real-time image of the camera through your mobile phone or computer, allowing users to view the image of the camera anytime and anywhere, to better protect the security of your home or office.
At present, cameras have been widely used in the security industry to monitor buildings, parks, schools and other places to protect the safety of the people. It can also be used in commercial places to help businesses achieve intelligent management, improve business environment and improve service quality.
2: Working principle of camera
The working principle of the camera is to reflect the light to the sensor, convert the signal captured by the sensor into a digital signal, and finally send it to the computer to display the image. Then the camera can capture the static and dynamic images in the picture.
The sensor of the camera is the most important part. It can capture light and convert it into electrical signals. There are many types of sensors, the most common are CCD and CMOS sensors, which can be used to capture images.
