Step into middle age and eat more black food

After entering middle age, people have begun to quietly degrade various physiological functions. At the same time, with the growth of age, the accumulation of fat and blood lipids are increasing, and arteriosclerosis, hypertension, cardiovascular diseases, and obesity have come one after another. Because of the weakened immune function and frequent epidemics, there is a decline in memory, thinking, and sexual function. Obviously, these signs are undoubtedly the seeds of aging. Therefore, after the middle age, we should eat more black products on weekdays, and we can supplement kidney and prolong the year.

Black foods include black rice, black beans, black dates, black fungus, black sesame seeds, bean pods, kelp, mushrooms, and the like. The diet of traditional Chinese medicine has related theories of five colors and five internal organs, namely "black into the kidney." In the spring and autumn and the Warring States period, people in our country used black food to supplement kidney qi to prevent premature aging and called it "longevity food."

Today, the whirlwind of black food has swept the world. Middle-aged and older people have used it for longevity. Scientific research results confirm that the nutritional content of black foods is higher than other color products, such as black rice, contains 17 kinds of amino acids, iron, phosphorus, calcium and a variety of vitamins; black sesame contains lepidhinin phospholipids, protein and rich in calcium Black fungus contains phospholipids, brain phospholipids, adenosine, etc., eat often help gastrointestinal digestion, enhance hematopoietic function. Improve hemoglobin content, improve blood viscosity, reduce serum cholesterol, triglyceride levels, but also stimulate the endocrine system, regulate human physiological functions, but also to prevent gastroenteritis, anemia, cardiovascular and cerebrovascular diseases susceptible to middle age , cancer, etc.

What is DVR Mini Camera

Dvr, which is called DigitalVideoRecorder in full, is a digital video recorder. Compared with traditional analog video recorders, dvr uses hard disk for recording, so it is often called hard disk recorder, also called DVR. It is a set of computer system for image computing, storage and processing. It has the functions of long-time video recording, recording, remote monitoring and control of images/voice and dynamic frames. DVR integrates five functions, including video recorder, picture splitter, PTZ lens control, alarm control, and network transmission. One device can replace a large number of devices in the analog monitoring system, Moreover, it has gradually gained advantages and popularity in terms of price.

DVRs cannot support IP cameras. From a general definition, products called DVRs generally do not support IP network cameras. Digital DVRs generally refer to converting video data captured by analog cameras into digital recordings, and do not include IP network transmission. By definition, DVR intelligence supports the input of analog signals. Therefore, if the DVR supports IP cameras, it is necessary to decode the IP cameras into analog signal signals using a decoder in the front section before entering the DVR.
The "digitalization" of DVR means that compression and storage technology is aimed at digital signals, rather than directly transmitting digitally encoded video images. Therefore, DVR must be deployed near the analog camera.

The function of DVR, with the increase of various voltage sensitive loads in the distribution network, puts forward higher requirements for power quality. However, due to system accidents in the power system, the voltage flicker, drop and other disturbances caused by the startup and shutdown of large equipment, lightning stroke and other principles are unavoidable. Moreover, in the current power grid, the ability to quickly restore power supply after power interruption is far from meeting the requirements of many sensitive loads. Therefore, it is necessary to provide users with stable and uninterrupted high-quality power when interference occurs. Dynamic voltage recovery (DVR) is the choice to solve the above problems today. DVR is connected in series to the feeder line that requires high-quality power to realize dynamic real-time voltage compensation for the line, so that the load end can get the desired high-quality power, and ensure the normal and uninterrupted operation of sensitive user equipment.
