Trailer Tracking
Trailer tracking is tracking the position of an articulated vehicle’s trailer unit through a tracking device fitted to the trailer. A communication network or satellite network is then used to transfer this positional data to a centralized collection point. Trailer tracking is used to increase productivity by optimizing the use of trailer fleets. Trailer tracking system Trailer tracking systems can provide essential information to trailer operators on; status, location, door activity, coupling/uncoupling, and history. These systems utilize the information to provide reliable and protected services to shippers of perishable commodities. Trailer Tracking is also a trucking term in which, when a Semi turns a corner the trailer tires will be closer to the curb (even jump the curb if semi turns to sharp) than the truck cab will be. Trailer tracking systems require 4 essential components to operate. # Tracking Device # Communication Network # Back-end Server and Database # User Inte ...

Semi-trailer Truck
A semi-trailer truck (also known by a wide variety of other terms – see below) is the combination of a tractor unit and one or more semi-trailers to carry freight. A semi-trailer attaches to the tractor with a type of hitch called a ''fifth wheel''. Other terms There are a wide variety of English-language terms for a semi-trailer truck, including: American English: *Semi-trailer *Semi-truck *Truck & trailer *Semi *Big rig *Tractor-trailer *Eighteen-wheeler British English: * Articulated lorry * Artic (short for articulated lorry) * Juggernaut *Heavy Goods Vehicle/HGV Canadian English: *Transport truck *Transfer truck Regional configurations Europe The main difference between tractor units in Europe and North America is that European models are cab over engine (COE, called "forward control" in the United Kingdom), while the majority of North American trucks are "conventional" (called "normal control" or "bonneted" in the UK). European trucks, whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-trailer
A semi-trailer is a trailer (vehicle), trailer without a front axle. The combination of a semi-trailer and a tractor truck is called a ''semi-trailer truck'' (also known simply as a "semi-trailer", "tractor trailer", or "semi" in the United States). A large proportion of a semi-trailer's weight is supported by a tractor unit, or a detachable front-axle assembly known as a dolly (trailer), dolly, or the B-Train, tail of another trailer. The semi-trailer's weight is semi-supported (half-supported) by its own wheels, at the rear of the semi-trailer. A semi-trailer is normally equipped with landing gear (legs which can be lowered) to support it when it is uncoupled. Many semi-trailers have wheels that are capable of being totally dismounted and are also relocatable (repositionable) to better distribute load to bearing wheel weight factors. Semi-trailers are more popular for transport than Trailer (vehicle)#Full, full trailers, which have both front and rear axles. Ease of backing i ...

Communication Network
A telecommunications network is a group of nodes interconnected by telecommunications links that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of circuit switching, message switching, or packet switching, to pass messages and signals. Multiple nodes may cooperate to pass the message from an originating node to the destination node, via multiple network hops. For this routing function, each node in the network is assigned a network address for identification and locating it on the network. The collection of addresses in the network is called the address space of the network. Examples of telecommunications networks include computer networks, the Internet, the public switched telephone network (PSTN), the global Telex network, the aeronautical ACARS network, and the wireless radio networks of cell phone telecommunication providers. Network structure this is the structure of network general, every teleco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which are small CubeSats. Similar satellites can work together as groups, forming constellatio ...

Productivity
Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time. The most common example is the (aggregate) labour productivity measure, one example of which is GDP per worker. There are many different definitions of productivity (including those that are not defined as ratios of output to input) and the choice among them depends on the purpose of the productivity measurement and data availability. The key source of difference between various productivity measures is also usually related (directly or indirectly) to how the outputs and the inputs are aggregated to obtain such a ratio-type measure of productivity. Productivity is a crucial factor in the production performance of firms and nations. Increasing national productivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GPS Tracking Server
A GPS tracking unit, geotracking unit, satellite tracking unit, or simply tracker is a navigation device normally on a vehicle, asset, person or animal that uses satellite navigation to determine its movement and determine its WGS84 UTM geographic position ( geotracking) to determine its location. Satellite tracking devices may send special satellite signals that are processed by a receiver. Locations are stored in the tracking unit or transmitted to an Internet-connected device using the cellular network (GSM/GPRS/CDMA/LTE or SMS), radio, or satellite modem embedded in the unit or WiFi work worldwide. GPS antenna size limits tracker size, often smaller than a half-dollar (diameter 30.61 mm). In 2020 tracking is a $2 billion business plus military-in the gulf war 10% or more targets used trackers. Virtually every cellphone tracks its movements. Tracks can be map displayed in real time, using GPS tracking software and devices with GPS capability. Architecture A GP ...
