Location traffic for traffic calculation, traffic calculation formula

In order to ensure real-time grasp of the vehicle's location, these 1,000 vehicles must upload location information continuously at small intervals

When the speed is 0, the location information is not uploaded; Upload location information every 1 minute when no load; Upload location information every 5 minutes, 3 minutes, and 1 minute when reloaded.

Assuming that the empty-to-weight ratio of the vehicle is 5:5 per day, and 4 hours of rest and parking are excluded each day, then the flow rate of this section is:

When unladen (1 minute): 500 vehicles (20 hours 60 minutes) 1 110 = 63m;

Heavy load (5 minutes): 500 vehicles (20 hours 60 minutes) 5 110=13m;

Heavy load (3 minutes): 500 vehicles (20 hours 60 minutes) 3 110=21m;

Heavy load (1 minute): 500 vehicles (20 hours 60 minutes) 1 110 = 63m;

The total traffic of uploading location information per day is as follows:

Heavy load (5 minutes): 63 + 13 = 76m

Heavy load (3 minutes): 63 + 21 = 84m

Heavy load (1 minute): 63 + 63 = 126m

Then the total monthly flow is 76 * 30 = 2280m, 84 * 30 = 2520m, 126 * 30 = 3780m, respectively

The formula for calculating the gas flow rate: q=sv s--gas cross-sectional area v--gas flow rate and water flow calculation method and formula:

There is resistance to flow, and the flow is related to the length of the pipe. Suppose the water source pressure is 3 kg square centimeter. From the water source, a horizontal pipe with a length of DN300 and L is directed to a certain place, and it flows freely at the end of the pipe. The flow rate can be calculated as follows:

3 kg square centimeter pressure is equivalent to 30 meters of water head, expressed as h= 30m. The length of the pipe is 1000m

The specific resistance of the DN300 tube is s=

Flow rate q=[h (sl)] 1 2)=[30 ( m3 s = m 3 h

The resistance is proportional to the length of the tube, the short tube has a large flow, and the long tube has a small flow) There are two units of network traffic.

One is byte bye and the other is bit

KB means 1024 bytes.

KB means 1024 single digits.

A byte is 8 bits.

That is, b=8b k is the meaning of thousand, and 1kb=1024b=8*1024b

If it is a mobile phone Internet traffic unit, the traffic unit is 1GB=1024MB, 1MB=1024KB, and 1KB=1024B.

Equal to the flow velocity multiplied by the cross-sectional area.

No traffic consumption;

GPS uses satellite positioning;

GPRS uses signal towers - telecom base stations and other east-east positioning; The two wood have a half-dime relationship;

The reason why mobile phone software positioning consumes traffic is because you want to load map data, or a mix of two positioning methods, but you have data, and you turn off the data connection, so how can it consume traffic? If you think my answer is good, please take it, ask for praise, oh dear

The principle of GPS positioning through satellites is as follows:

GPS doesn't consume data for the following reasons:

GPS is data-consuming. Even if the mobile phone does not have a SIM card and is not connected to WiFi, it can be located by turning on GPS. Of course, when there is no network, it will not affect the GPS positioning function of the mobile phone.

Without the Internet, it can also receive GPS satellite location information through the antenna, just like the radio, and then calculate the latitude and longitude of the location.

Why does mobile GPS location consume a lot of data?

Does the phone consume battery when GPS is turned on:

The GPS module is quite power-hungry, because it will constantly search for satellites and constantly adjust the positioning accuracy, and the mobile phone can't stand the toss at all. As soon as many friends take the train, the power of the mobile phone is consumed very quickly, also because during the train ride, the mobile phone will constantly search for communication signals, resulting in the loss of power. So if your phone's battery is not in use, check to see if the GPS is turned on.

No, but it will be very power-hungry.

Yes, both traffic and battery are draining.

Through the satellite data positioning corresponding to the GPS module, more than 3 satellite signals are required to determine your position. It has nothing to do with GPRS data traffic.

Changing the physical location has nothing to do with mobile phone traffic, the mobile company only cares about the access you access from that place, he charges from **, and you are located to the north stool in Beijing, but you are in Shanghai, and your mobile phone must be connected to the entire network through the base station in Zaonapi Shanghai.

And the mobile phone navigation has the function of car navigation does not necessarily have Oh, that is, the mobile phone navigation can exchange data with the official server to get the latest traffic information, car navigation does not seem to be possible.

Provide professional driving voice navigation, real intersection maps and real-time road conditions, a necessary artifact for driving travel, and can avoid the dilemma of traffic jams.

With national offline map data, save more than 90% of the traffic, even if the phone is down, you can not get lost.

And the surrounding area is also good. One-click taxi. **。Preferential. Good food all around. Hotel. Entertainment, everything you need. Very sweet.

Hello, the traffic that can be used in mobile phone navigation is that satellite positioning needs data first, and in one is that in the navigation process, it needs to constantly buffer the map package data, which is more consuming of mobile phone traffic. However, you can install a Tencent map software on your mobile phone, and you can directly use the software client ** city offline map package, which can achieve the purpose of saving mobile phone traffic. It can also be fast, flexible and accurate positioning, helping users find their location on the map; Provide a variety of routes for taxi bus self-driving, and support taxi valuation in nearly 200 cities across the country, public transportation in 210 cities and self-driving in nearly 400 cities; Query the real-time traffic condition information of the city's main roads, drive navigation to avoid congestion, and support up to 18 cities; Help users search for the nearest restaurants, hotels, gas stations, etc., and provide fresh and thoughtful information about places to eat, drink and play.

When using offline map navigation, you can enter the starting point and end point, whether it is walking or bus, there is a detailed route navigation, and the route is also clearly presented on the map.

Hope mine can help you.

Well, landlord, why do you want to use a mobile phone that consumes a lot of data to navigate?

With Tencent Maps' Street View, users can take a virtual tour online and learn about the surrounding environment of a place before going to it, making it easier to find their destination. At the same time, the Street View map can also provide reference information for buying and renting a house.

And there is no charge, it is really worth the money!

Mainly**traffic goes more, about 1m or so at a time, if you don't want to waste traffic,**an offline data package is OK,very simple,Generally**you commonly use a few cities,It is best to save traffic in the case of wireless network**, choose an offline map,**you want a city map,it's done,it's very simple,you can use Tencent map,**Offline map is very simple,It's easy to use。 The route is particularly clear, the voice navigation is also accurate, and there is no need for traffic after that, which is particularly practical.

Hope to solve your problem and give a kind upgrade that needs yours! Thank you!

I use Tencent Map Turn on the offline mode to use the offline map You can also navigate offline The official website provides data package** All free The average data package size of a single city of the mobile phone Tencent map is about 3m, and the program and the data package can be installed on the mobile phone If it is a national map data package (about 500M), it is recommended to install it on the SD card The compatibility is also very good There has been no crash The flashback situation is also very convenient to operate.

It's all free now and it's all offline map packs.

It's the 3G 2G traffic consumed, calculated by the mobile company.

For example, the flow rate is like tap water, it has nothing to do with time, for example, if you have 10m of flow, you can use it up in 1 hour, or you can use it up in a month. How much you use depends on your own usage!

Hello, first of all, thank you for your support to China Telecom. According to your description, there may be a delay in the system, you can log in to the online business hall - self-service - phone bill inquiry - Internet list query to check your Internet list and the actual situation of traffic usage. If you need to check the bill and pay the phone bill, please log on to the Anhui Telecom online business operation or hall.

Have a great day! I hope that rushing to mine will help you and get yours!

Let's say your table is sheet1

Write the formula in another table A1:

if(right(sheet1!a1,2)="gb",value(left(sheet1!a1,len(a1)-2))*1024,value(left(sheet1!

a1,len(a1)-2)))

Then drag it horizontally to the same size as sheet1.

Assuming that the data are in the Sheet1 table, the results are obtained in the corresponding position in the Sheet2 table and entered in the Sheet2 table A1.

if(right(sheet1!a1,2)="gb",substitute(sheet1!a1,"gb",)*1024&"mb",sheet1!a1)

Then pull right and then pull down to copy the formula.

Are you sure that there is no KB, if it is both GB or MB, assume that the data is entered in A1:C100 and D1.

if(countif(a1,"*mb"),a1,substitute(a1,"gb",)*1024&"mb")

Pull two squares to the right and pull down.

Make a copy first, write 1024 to the blank cell and Ctrl+F to find GB and replace it with blank.

Each column is then arranged in ascending order.

Copy 1024, select the value without MB, and paste Multiply.

Enter or copy-paste this formula in e1.

if(right(a1,2)="gb",left(a1,len(a1)-2)*1024&"mb",a1)

Pull-down fill, pull-right fill.
