Navigation electronic dog and the flow velocity of the electronic dog?
Time:2016-05-10

Special purpose vehicle electronic equipment increasingly renovation, from the initial electronic dog, portable PND to now embedded special purpose vehicle navigator, GPS and radar navigation integrated machine and so on, it may be said to be flourishing. However, we find that businesses often use some so-called product concepts to mislead consumers. Take the electronic dog and navigator, with the progress of science and technology, between the two relations more and more ambiguous, a lot of navigator brands claim their products with warning function, and consumers sometimes are often confused, with the early warning function of the navigator, whether it is electronic dog navigator. Real will buy back the navigator, discovered the warning function of defective products. The electronic dog (early warning system) that is commonly said can be considered to have two interpretations: a software or a combination of hardware or software and hardware.


We start to understand the difference between navigator and electronic dog:


1, the electronic eye (also known as the electronic police): radar speed meter commonly known as the electronic eye, also known as electronic police, is currently widely used in urban transportation. Is according to the calculation of the amount received reflected wave frequency displacement and that the velocity of the object to be measured, again through the application of technology of photoelectric imaging, automatic control, such as communication, computer network to measure whether the speeding car, fixed and mobile two, fixed in a bridge or a crossroads, the flow of general installation in the patrol car. "Electronic eyes" is mainly of motor vehicles running red lights, retrograde, speeding, more lane, violation of the dock illegal behavior, to achieve all-weather monitoring, vehicle violation of graphic information capture and according to the illegal information were afterwards, is a kind of new management mode of transportation.


2, "electronic dog": "electronic dog" is prior in police radar equipment investment buried electron emitter, electron emitters emit waves when it is close to the police radar equipment will give an alarm. Because the electronic dog warning belongs to passive to warn the drivers. In other words, manufacturers need to in front of the camera, investment buried emitter, but due to the transmitter power sources in battery (as we used cell phone batteries, after a break time would have no power). As a result, the electronic dogs sometimes lose the ability to smell. "Electronic dog" main function is for a fixed camera rod issued a warning, at the lowest price is the most attractive, because efficiency has an area (buried emitter early warning, buried and investment in the future is not warning), sex of effectiveness for a given period of time (generally 6-10 months). So if the manufacturer does not want to continue to throw the embedded transmitter, the electronic dog occurs without utility as. Occasionally occur electronic dog barking or not call, this is because the transmitter or did not vote cast their mess, buried. Also because the police have some mobile police photographic ban is not a fixed place, so can not be pre cast buried emitter, so some brands of electronic dog on the flow velocity to the role, coloured shadows electronic technology dog dogs and electronic industry as a leader, flow velocity and fixed speed a kind of sensitive.


3, GPS navigator, GPS operation relies on global positioning system (by space satellite, ground control and user receiving three parts). Main function for the map query (you can search you to the destination position on the operating terminal can record you often want to place the location information, and preserved, and can share with others the position information and fuzzy query your attachment or near a position such as gas stations, hotels, ATM machines and other information), route planning (GPS navigation system will according to you to set the starting point and destination, automatic planning a route, route planning can set whether to go through some way. Automatic navigation (voice navigation, picture navigation, re planning line). Thus, between the navigator and an electronic dog still have many differences, in the US in everyday driving, GPS can we find destination, and can help us to the right path planning and less detours. While the electronic dog is able to let us eat less ticket, eliminating the need to spend a sum. For example, we used a navigation map Kay, cjt, Tong Road, Lingtu, NavInfo, traveler, GORD, payease, Garmin, Igo, and so on.


The difference between the navigator and electronic dog actually only these, is actually very different.


Safe trip, you have me
