Physical weakness, sweating, lethargy, summer inflammation is not always make you feel no spirit? Maybe you think that this is just a reason for not having a good rest, but in fact what you really need is a reasonable means of health care. In the summer, it seems that TCM and Long Summer (the last 18 days of the summer and autumn season) reflect the characteristics of heat and heat, and people of different physiques need different methods of health.
Positive physique health
â—Summer common symptoms:
More sweating, irritability, thirst, yellow urine, dry stool, easy bleeding (cerebral hemorrhage, epistaxis, hemorrhoids bleeding, menstrual flow, etc.), insomnia and so on.
should
Where irritability, excessive sweating, insomnia, yellow urine, dry stool, bleeding tendency, can eat bitter foods such as: bitter gourd, andrographolide, Houttuynia, bitter chrysanthemum and other foods. Those who are thirsty, drink cold water, have yellow urine and less body fluid can eat juicy, juicy foods like watermelons, melons, coconut milk, etc., and pay more attention to supplemental water.
avoid
Spicy, alcohol (various alcoholic drinks), barbecue, coffee, strong tea, smoking, especially for people with high blood pressure, should be strictly taboo, so as to avoid the rise of blood pressure with heat caused by the inverse of the brain caused by blood Bleeding.
â— Long summer common symptoms:
Long summer and wet, positive constitution people common hot and humid symptoms at this time: irritability, head weight, such as wrap, chest tightness, bitter mouth and sticky, sweating sticky, loss of appetite, acute diarrhea, abdominal pain, yellow urine, dripping, not purging, frequent urination Urinary urgency, accompanied by more than the amount of odor, eczema and urticaria, lice and so on. The tongue coating is often greasy or greasy and the tip of the tongue is red.
â— living conditioning:
Long summer moisture is heavy, should pay attention to indoor ventilation; pay attention to bathe, keep the perspiration unobstructed; avoid excessive greedy and hurt the spleen and stomach; should increase outdoor sports, in order to promote the body's patency and increase appetite.
Partial negative health
â—Summer common symptoms:
The limbs are easy to be cold, and are particularly sensitive to the coldness of the climate. Their faces are paler than ordinary people. They like to drink hot drinks and rarely thirst. Even in the summer, entering the air-conditioned room will feel uncomfortable. You need to have a hot cup of tea or add an extra coat to feel comfortable.
should
In the summer, the yang floats outside and the internal organs become cold. Therefore, warm food and warm food should be eaten, such as: ginger, onion, garlic, basil, Nepeta, beef and mutton.
avoid
People with a negative constitution should not eat too much oil, but also try to eat raw vegetables, fruits, sweets, sour foods and cold foods. In addition, the greenhouse production of vegetables should be eaten as little as possible, such as wild vegetables, seaweeds; for tea, raw water, but also try to control the intake, can not drink.
â— Long summer common symptoms:
Long summer and wet, people with negative constitution often have symptoms of coldness at this time: lethargy, fatigue, sore body around the body, heavy swelling of the joints, head weight, such as wrap, chest tightness, pale mouth, thirst, vomiting, swelling, sweating, sticky, appetite Decrease, abdominal pain, acute diarrhea, unfavorable urination, thinning, etc. Common tongue greasy tongue, pale tongue, or water slippery moss.
â— living conditioning:
People with partial or negative constitution should pay attention to walking outdoors more often, do some outdoor sports suitable for them, and make yang gas stretched; try to avoid prolonged bed rest; pay attention to keeping warm, not greedy, especially pay attention to the joints of the chest, abdomen and limbs Keep warm; moderate exposure to moderate sunlight is beneficial to the body.
Since the 21st century, as the network technology develops, there is more and more demand for the storage of video data via the network. And then the monitoring system has further developed into an NVR(Network Video Recorder) system with network functions, from the DVR(Digital Video Recorder) system.
The Network Video Recorder, also called the NVR/ Network Video Recorder NVR/ NVR in CCTV/ NVR CCTV System/ NVR Recorder, is the storage and forwarding part of the network video surveillance system. The Network Video Recorder, without the analog-to-digital conversion and encoding functions, works with the video encoders(DVS) or the network cameras(IPC) to realize the video recording, storage and forwarding functions.
Let's see the specific software functions of the Network Video Recorder:
1. The user interface layout
The NVR software interface (GUI) is a human-computer interaction window. All the functions of the system, such as these operations of the channel parameter setting, the start and stop recording, the video browsing, the video playback, the video export, the PTZ control, and so on, are completed through this user interface.
The user interface layouts of different NVR manufacturers may vary greatly, but the main functions are similar. Generally speaking, the human-machine interface should have the reasonable layout, the applicable functions, and the simple operation, so as to conform to the user's operating habits.
2. The video browsing function
Generally speaking, all the video and audio channels in the system (including the channels under other NVRs) can be added to and displayed on the NVR software platform. A clear structured channel resource directory tree can be formed on the GUI to directly perform the on-site video browsing operations, with no need to firstly log in and connect different NVRs to load different NVRs first. There are two ways to browse the on-site video. One way is to directly drag the corresponding channel on the left to the target window display area, and the other way is to select the display window first, and then enter the shortcut key of the channel on the keyboard and press Enter.
3. The recording and storage function
The recording and storage function supports the video recording, storage, and backup.
4. The playback and export function
(1) The multiple playback modes
The video playback has a variety of modes, including the playback in time periods, fast playback of the alarm videos, and reverse playback at any time, and so on. During the playback, the user can play the video frame by frame, and also can add markers to the playback clips, so that he/she can find the corresponding clip he/she need easily when he/she needs in the future. Besides, various operations such as the normal playback, accelerated playback, slow-down playback, pause, and stop, can be performed during playback.
(2) The video export
(3) The multi-channel playback
If some on-site incidents occur, in order to fully know the situation of the surrounding scenes at that monitoring point, sometimes it is necessary to synchronize the playback of the videos from multiple channels, which will facilitate the panoramic display of the entire process of the event.
5. The incident investigation
6. The user authority management
7. The user operation log
8. The equipment management
In conclusion, the Network Video Recorder technology has been widely promoted and applied to the fields of urban security storage, national security and other engineering projects, because of its own advantages in many aspects. And the Network Video Recorder technology is bound to become the mainstream technology in the field of urban security high-definition video surveillance because of the driving of the market, technology, and so on. Undoubtly, the Network Video Recorder technology has very strong prospects for the theoretical research and practical application.
