In HD network video surveillance systems, there are often friends who have feedback screen delays, stalls, etc. There are many reasons for this phenomenon, but in most cases the configuration of the switch is not reasonable enough, resulting in insufficient bandwidth.

Before a select switch

selection switch according to the code stream and the number of cameras, we must first figure out how much bandwidth per channel images occupancy.

Take the early IPC example:

720P network camera, the main stream is 2 ~ 3M, sub-stream is 0.8 ~ 1M, a total of about 4M.

1080P network camera, the main stream is 4 ~ 6M, sub-stream is 0.8 ~ 1M, a total of about 7M.

Second, we must clarify the bandwidth capacity of the switch. Commonly used switches are fast switches and gigabit switches. Their actual bandwidth is generally only 60 to 70% of the theoretical value, so the available bandwidth of their ports is roughly 60Mbps or 600Mbps.

In terms of network topology, a LAN is usually a two-to-three-tier structure. Connect the camera to the access layer. Generally, a 100M switch is enough, unless you have a lot of cameras on one switch.

The aggregation layer and the core layer are calculated according to how many images are aggregated by the switch. The calculation method is as follows: If a 720P network camera is connected, generally within 15 lines of images, using a 100M switch; if more than 15 lines, use a gigabit switch; The 1080P network cameras are usually within 8 channels of images, with 100M switches, and more than 8 Gigabit switches.

Second, the choice of network monitoring switches required

With the increasing use of high-definition video camera, how to choose the right, to meet the overall network infrastructure performance monitoring switch has become a program developed in the early HD monitoring system, Project quotations have a very important role. A suitable switch not only can play the function of monitoring the network and can effectively reduce the waste of resources.

The monitoring network has three layers of architecture: core layer, convergence layer, and access layer.

Take a 720P camera and use PoE power supply as an example, select the corresponding switch and connect the front-end switch every 20 720P to an access switch.

1, the conditional access select

layer switches 1: Mary camera stream: 4Mbps, 20 cameras is 20 * 4 = 80Mbps.

In other words, the access port switch port must meet the 80Mbps/s transmission rate requirements, taking into account the actual transfer rate of the switch (usually 50% of the nominal value, 100M also about 50M), so the access layer switch Should use the switch with 1000M upload port.

Condition 2: The backplane bandwidth of the switch, for example, if a 24-port switch is selected, two 1000M ports are provided, and a total of 26 ports, then the bandwidth requirement of the switch backplane at the access layer is: (24*100M*2+1000*2*2) )/1000 = 8.8Gbps backplane bandwidth.

Condition 3: Packet Forwarding Rate: The packet forwarding rate of a 1000 M interface is 1.488 Mpps/s. Then, the switching rate of the switch at the access layer is: (24*100 M/1000 M+2)*1.488=6.55 Mpps.

Normally, we will call the switches that meet conditions 2 and 3 as wire-speed switches. For example, the Fengduda PS1024 or PS3024 will satisfy the wire-speed switching capability, and it is also a suitable access PoE switch in this case.

Based on the above conditions, when there are 20 720P cameras connected to a switch, the switch must have at least one 1000M uplink port and more than 20 100M access ports to meet the demand.

2, selection switch convergence layer

or in the above example, if a total of five rich PS1024 access, the traffic aggregation layer: 80Mbps * 5 = 400Mbps, then the convergence layer uploaded The port must be above 1000M.

If five IPCs are connected to one switch, an 8-port switch is generally required. Then does the 8-port switch meet the requirements? You can see the following three aspects:

Backplane bandwidth: port number * port speed *2 = backplane bandwidth, ie 8*100*2=1.6Gbps

Packet exchange rate: port number * port speed / 1000 * 1.488 Mpps = packet exchange rate, ie 8 * 100/1000 * 1.488 = 1.20 Mpps. For some switches, the packet exchange rate is sometimes calculated to fail to meet this requirement. That is, non-line-speed switches are prone to delays when performing large-capacity throughput.

The bandwidth of the cascade port: the number of IPC streams* is the minimum bandwidth of the upload port, that is, 4.*5=20Mbps. In general, when the IPC bandwidth exceeds 45 Mbps, it is recommended to use a 1000M cascade port.

Third, how to choose the switch in network monitoring?

For example: There is a campus network, more than 500 high-definition cameras, stream 3 ~ 4 trillion, the network structure is divided into the core layer of the access layer convergence layer. Stored at the aggregation layer, each convergence layer corresponds to 170 cameras.

The problems faced: How to choose a product, the difference between Gigabit and Gigabit, what are the reasons that affect the transmission of images in the network, and what factors are related to the switch...

1, 2 times

backplane bandwidth capacity of all ports and port number of x should be less than the nominal backplane bandwidth, non-blocking wire-speed full duplex exchange switch has proved maximum data exchange performance conditions of.

For example, a switch that can provide up to 48 Gigabit ports with a full configuration capacity of 48×1G×2=96Gbps can ensure non-blocking wire-speed packet switching when all ports are full-duplex. .

2, the packet forwarding rate

full configuration packet forwarding rate (Mbps) = full configuration GE ports × 1.488Mpps + full configuration Mbps ports × 0.1488Mpps, wherein a Gigabit ports in the packet length word 64 The theoretical throughput of the festival is 1.488 Mpps.

For example, if a switch can provide up to 24 Gigabit ports and the advertised packet forwarding rate is less than 35.71 Mpps (24x1.488 Mpps = 35.71), then there is reason to believe that the switch is designed with a blocked architecture.

Generally, a switch that has both a backplane bandwidth and a packet forwarding rate is a suitable switch.

The switches with relatively large backplane and relatively small throughput not only retain the ability to upgrade and expand, but also have problems in the design of software efficiency/dedicated chip circuits. Switches with relatively small backplanes and relatively high throughput have relatively high overall performance.

The camera code stream affects the definition, which is usually the code stream setting of the video transmission (including coding and decoding capabilities of the code sending and receiving equipment, etc.). This is the performance of the front camera and has nothing to do with the network.

Usually the user thinks the clarity is not high, and it is actually a misunderstanding to think that the idea caused by the network causes.

In HD network video surveillance systems, there are often friends with feedback screen delays, stucks, etc. There are many reasons for this phenomenon, but in most cases the configuration of the switch is not reasonable enough, resulting in insufficient bandwidth.

Based on the above case, calculate:

Stream: 4Mbps

Access: 24*4=96Mbps<1000Mbps<4435.2Mbps

Convergence: 170*4=680Mbps<1000Mbps<4435.2Mbps

3, the main consideration

access switch to access the link bandwidth between the convergence, i.e., the link capacity associated switch requires more than the number of simultaneously receiving a camera * rate. In this way, there will be no problem with real-time video recording. However, if a user sees the video in real time, the bandwidth needs to be taken into account. The bandwidth occupied by each user to view a video is 4 M. If each camera of an access switch is If one person is watching, the bandwidth of the camera *bit rate*(1+N) is needed, ie 24*4*(1+1)=128M.

4, convergence switch

convergence layer 170 need to process camera 34M stream (170 * 4M = 680M), the aggregation switch means and forward the need to support more than 680M-exchange capacity. General storage is connected to the convergence, so video recording is wire-speed forwarding.

But to take into account real-time viewing of monitored bandwidth, each connection occupies 4M, and a 1000M link can support 250 cameras to be debugged. Each access switch connects 24 cameras. 250/24, the equivalent of the network can withstand the pressure of each camera at the same time 10 users in real-time viewing.

5, core switches

core switches need to consider switching capacity and link bandwidth to converge, because storage is placed in the convergence layer, the core switch video is no pressure, that is as far as the number of people watching at the same time How much road video can be. Assume that in this case, there are 10 people watching at the same time. Each person sees 16 videos, that is, the exchange capacity needs to be greater than 10*16*4=640M.

6, switch to select video surveillance in focus

LAN switch selection, select the access layer and aggregation layer switches typically only need to consider factors exchange capacity is enough, because users usually by a core switch Connect and get video.

In addition, because the main pressure is at the convergence layer switch, because it is necessary to bear the burden of monitoring the storage, but also bear the pressure of real-time viewing call monitoring, so it is very important to select the appropriate aggregation switch.

For the access switch, there is no essential difference between the ports that connect the cameras to the downstream ports at 100Mbit/Gigabit, but the uplink must be Gigabit.

The old man practises love promises to bring his wife to the country

30 million years ago, I traveled to more than 600 sites in China to write 2 million words and recorded 20,000 photos.

When he was in love, he was remembered. In the more than 10 years after his retirement, the old couple traveled to more than 600 domestic scenic spots. They photographed over 20,000 travel pictures and recorded more than 2 million words of travel diaries. Uncle Dong, 67, said that this was his wish-won journey to his wife. The two diary's diaries and photographs are the most precious treasures they left for their children and grandchildren.

Remembering the promise before marriage is always in mind

On the afternoon of October 10th, 67-year-old Dong Xuan and his wife looked at travel diaries and photo albums at home... The smiles of happiness and happiness were on their faces. The two also exchanged views from time to time. The two were full. Love.

Uncle Dong and his wife Li Axi who lived in Shenbei New District were all 67 years old. Uncle Dong was wearing a slightly faded suit and was wearing a pair of bronze trousers. His wife was wearing a blue short sleeve and was wearing a pair of white pants. "Our clothes are from friends and family. We haven't bought new clothes for more than 10 years. The retirement salary is used for travel."

Uncle Dong smiled and said: "A book of travel diaries and travel photos are the biggest gains."

In 2002, Uncle Dong retired from the Highway Management Office; in 1997, his wife retired from the engineering team. “We were introduced by others. When we talked with each other, we discovered the same interests and interest in Chinese history and geography and culture. The first time we met each other left a very good impression.” Before getting married, Dong Grandpa once said to his wife, “You marry me. In the future, I will take you around the great rivers and rivers to visit the famous places of the motherland.” This became a promise between the two people! “At that time I also remembered the diary. in."

After more than 30 years have passed, his wife has already forgotten this promise. Uncle Dong has always kept his mind in mind. After finally retiring, Uncle Dong found the journal of the year and his wife shed tears excitedly. From then on, the two began a joyful tour of life.

Departure travel sit hard seat basically do not buy sleeper

In 2002, Uncle Dong's pension was 1,000 yuan, his wife's pension was 600 yuan, and the two added up to less than 2,000 yuan, but not rich pensions did not stump them. "We have a good discussion. Month 800 for life, another 800 for travel."

Really want to go, Grandpa Dong found that there was so much to prepare. “My main reference is to travel across China and several other books to formulate a travel plan, categorize the various scenic spots by geographical location, and then bring them to neighboring provinces, and go out and take a trip. Our first stop It is Beijing."

With the plan, you will have money. In order to save every penny, to see more attractions and buy more tickets, Dong and his wife prepared two packages for the first time before they set off. They include instant noodles and biscuits. “We eat instant noodles in the morning and eat at noon. The biscuits went out early every morning and came back very late. In less than 10 days of travel, we both lost 9 pounds. But when I was standing in Tiananmen Square, I was in a state of excitement and cheered and jumped with my wife.” Before leaving, Uncle Dong took The residence booklet also brought a marriage certificate. “When I was staying at the hotel, I handed in the marriage certificate. The staff members took a look at us and smiled and said how happy a pair of old people are. There is an ID card on the list... We both laughed."

Uncle Dong and his wife go out in the end of spring every year for about a month. Some 10 days, some more than 20 days, and more than a month. Every time he goes out, the old couple both try to bring enough food to eat, so that they don't need to go outside to eat a restaurant. “In general, we are both self-guided tours because the group is constrained and the غير مجاز مي باشدt is high.” Uncle Dong said, if you go In a circle, when the money came back, the old couple left another short walk in the fall.

The longest time Dong and his wife had gone were five provinces and autonomous regions in the northwest, including Inner Mongolia, Ningxia, Gansu, Qinghai, and Xinjiang. “This is 34 days and غير مجاز مي باشدts more than 8000 yuan. After returning, we both lost 10 kilos. Because both of us are 'hard to the end' wherever we go, we never buy a sleeper, and we all ride in the night train, which can save the hotel's غير مجاز مي باشدt."

In these years, the only place where the old couple needed to spend money was to buy shoes, and the shoes must be bought well, or they would be guilty of going out too. In the meantime, Uncle Dong’s worn-out shoes have two or three pairs of shoes.

Animated singing to everyone refreshing everyone to give him birthday

Although tourism is very hard, Dong and his wife have gained a lot of happiness and left them with wonderful memories.

In 2003, the old couple went to Guilin. “In the past, we all read articles describing Guilin landscapes. When we really set foot on this land, the greatest feeling was that people were painting in the middle.” When playing in the Lijiang River, It was exactly on the 53rd birthday of Uncle Dong. "We bought local shrimp, fish, drinks and other specialties and had an unforgettable birthday in the beautiful scenery."

The unforgettable part of the old couple's uncle is that in 2011, they went to Tibet and Chongqing for tourism. In that 23-day tour, they harvested so much happiness. Uncle Dong recalled that on the way from Lhasa to Linzhi, it was Panshan Road, which was more than 5,000 meters above sea level. “One driver and 28 tourists, because people in the car are lethargic because of the altitude, even the strength of their speech is gone. At that time, I felt that this was very dangerous and I would be unpredictable when I was not careful. So I stood up and stood in the aisle and introduced myself. 'I am a Shenyang person. In order to raise everyone's praise, I sing it to everyone. The song... "A "Always a Friend" has driven everyone away."

As Uncle Dong continued to sing and tell jokes, the tourists in the car gradually got up. Some people began to applaud. Someone began to sing along and sang together. Finally, the driver sang together. “The tour guide looked at my ID card and discovered that the day was just me. On the 59th birthday, they gave me a birthday party. At the time, my husband and I were moved to tears."

Harvesting 20,000 photographs and writing 2 million word diaries

Speaking of the benefits of these years of tourism, the old couple opened their own cabinets, full of travel photo albums and travel diary: “This is the wealth we left for our children!” Before his uncle Dong’s husband had been a private teacher, “every time When I went out for a trip, I was responsible for taking pictures and my husband was responsible for recording. She recorded the time, location, what she saw, and the important scenic spots. After returning home, I reorganized the travel facts into a travel diary and photographed the pictures. Will be categorized."

Uncle Dong's travel diary is divided into two parts. One part is the introduction of scenic spots. The other part is the anecdotes, feelings, gains, and inspirations that tourism encounters. For example, “when traveling in Yangzhou, we just caught up with the local “March 3” holiday. When we went to see the bustle, we took photos and recorded some of what we saw and heard. We interviewed us. We also went to Yangzhou TV station that night. These will be recorded in the travel journal.”

In the postscript of the tour, Master Dong wrote: "This travel diary began on October 12, 2014. Before the copy was written from the computer of the various scenic spots and museums... Our biggest feeling was that as long as we could move, we had been Walk down forever! Learn all the time, forever! Write it down forever.”

Over the past 600 years, over 600 scenic spots have been traveled. The diary has recorded about 2 million words and used more than 40 large notebooks. Tourist photographs have taken more than 20,000 pictures. These pictures have been compiled by Master Dong, and the spine of each book has been Both recorded the time, location, and category of the photo shoot. Tickets and tickets alone are filled with more than 10 notebooks of 16 sizes.

Diaries and photos are the most precious asset for grandchildren

Reporter: What has been the biggest gain in your travels for over a decade?

Uncle Dong: Increase knowledge, broaden your horizons, make friends, and feel comfortable. In addition to these diaries and photos, a good body was also harvested. Now high blood pressure, heart disease, etc. are all good. When I was 40 years old, I went to Taishan and climbed for 4 hours. I returned to the cable car and came back for a week. After he retired, he did not go to the mountains to do anything. Travelling to Tibet, many young people were particularly serious about the altitude sickness.

In addition, he also trained his eloquence. Before speaking in front of strangers, he was nervous. Now he can speak eloquently, and for two or three consecutive hours he is not afraid.

Reporter: Travel spends all pensions. Does the child support you for this type of retirement?

Uncle Dong: The daughter and son-in-law are particularly supportive. A full two-door travel diary and photographs are the most precious wealth we have left for our children and grandchildren. However, they did not agree that we should buy hard seats and worry that I and my wife could not eat too much. Once my husband and I traveled to Kunming, and my daughter knew that she had bought a hard seat and said that she would not be allowed to change to a sleeper. In the end, my wife and I didn't say anything to my daughter and I had to go to sleepers.

Reporter: What is the greatest feeling of travel?

Uncle Dong: Knowledge changes fate, this is particularly evident in tourism.

Many people have purchased data collectors and scanners, but they do not know what's different between them. Let's talk about differences between data collectors and scanners:

1. Data collector, commonly known as inventory machine. There is a memory that can be used without connection to a computer, and the distance from the computer is not restricted, and even different cities can use the network. The scanned data is first stored in the memory of the collector, and then the data is transmitted to the computer server through the transmission base or GPRS or wireless WIFI to complete batch processing. Second, the collectors have large screens and you can see the scanned bar code information at any time. Finally, the collector has a keyboard. If the barcode is wrong, or the damage cannot be scanned, the keyboard can be used. The data collection system is relatively flexible and is a system that is tailor-made for a wide range of users. The data collector is converted into various physical quantities of electrical signals. Temperature, water level, wind speed, pressure, etc. can be analog or digital. Collection is usually a sampling method, that is, repeated collection of data at the same point at certain times. Most of the collected data are instantaneous values, and may also be a characteristic value within a certain period of time. Accurate data measurement is the foundation of data collection. Data measurement methods are touch-based and non-touch-based, with a wide variety of inspection components. Regardless of the method and component, the condition of the target under test and the measurement environment are all conditioned to ensure the correctness of the data.

2. Scanning guns, also called scanners. No memory, just instant transfer. When a USB cable (or ps2 port, RS232 port) is connected to the computer, a bar code is scanned and a code data is immediately displayed on your computer. Wireless scanners, also known as wireless scanners, can be used without connection to a computer, but the spacing is limited. Usually 100 meters, it is best to be accessible. Second, the scanner does not have a screen. The scanner will convert the bar code compiled according to certain rules into what the user can read, that is, the information it contains, the two processes of demand scanning and decoding.

With the development of smart phones, more and more mobile phones have become the standard for people's daily life. We are thinking that PDAs and mobile phones are also Android systems. Can we use mobile phones instead of PDA functions? And now mobile phones are in hardware. The system aspect is better than the PDA. Therefore, the WT01 wearable intelligent data acquisition terminal emerged. It can realize all the functions of the PDA in combination with the mobile phone, and it must be closer to the people in the secondary development than the PDA development because it is used in the Android mobile phone application. In development, the technology is more mature and the resources are relatively abundant. As long as it is a general Android software engineer, it can be easily developed.
