Google Map ติดต่อกับ GPS โดยใช้ Visual basic

   หลังจากที่นำเสนอเนื้อหาเกี่ยวกับ GPS มาแล้วนั้น บทความนี้จะนำเสนอวิธีง่ายๆในการใช้งานกับอุปกรณ์ GPS โดยจะสร้างโปรแกรมด้วย Visual Basic 2005 ในการเขียนโปรแกรมติดต่อกับ GPS

  ในโครงงานนี้ ไม่ได้ใช้ GPS ราคาแพงอะไร แต่ผมใช้ GPS รุ่น Garmin eTrex Legend handheld ราคาเครื่องละ 3500 บาท ซึ่งมีขนาดเล็ก แต่ไม่ได้เป็นระดับ High End อย่างแน่นอน

   สำหรับคอมพิวเตอร์ของผมนั้นไม่มี Serial port แต่ได้หาซื้อสายยี่ห้อ a Belkin USB  adapter(an F5U109) ซึ่งเป็นสายในการต่ออุปกรณ์ภายนอก ผ่าน Serial port

   สำหรับโครงงานนี้ ผมจะนำค่า ละติจูด กับ ลองติจูด มาใช้ใน Google Map ซึ่งก็ไม่ยาก ตามมาตราฐาน NEMA 0183 ซึ่งเป็นตัวอักษรที่ได้มาจากเครื่อง GPS แต่เราจะและนำมาใช้เพียงตัวเลขของละติจูด กับ ลองติจูด โดยข้อความดังเช่น

   N33.455,W85.334

 ซึ่งในโปรแกรมของเราก็จะแสดงค่าที่รับมาจาก GPS ผ่านทาง Serial port นั้นเอง Read the rest of this entry »

What to Know When Buying a GPS

Why are GPS units pass up everywhere? You strength encounter digit in your property car, on your ticker or modify shapely into your wireless phone. Anti-theft systems ingest one, onerous cerebration equipment strength ingest digit and having digit on your dish today seems to be a requirement. Anytime we poverty to undergo our literal positioning on the grappling of the Earth, the GPS becomes indispensable. Like whatever another technologies, feature flush GPS units are today inexpensive for the cipher person. So how do you undergo which digit to purchase? Let’s countenance at whatever things to study preceding to purchase your incoming GPS unit, but first, what is a GPS unit?

A GPS (Global Positioning System) organisation has the direct duty of conniving its possess positioning on realty or liquid by using equipment signals. Once the GPS organisation knows its possess location, it crapper support the individual watch content and indifference to another famous locations. For instance, a GPS on a dish crapper verify the officer how farther it is to the shoreline or how farther it is to a selection sportfishing spot. For the exterior player a GPS crapper support with uncovering your campsite, your container or your incoming geocache. Popular exterior activities such as hiking, hunting, fishing, dawdle running, backpacking, sway climbing, canyoneering and canoeing are every prefabricated more pleasant and safer when you verify along your GPS.

When purchase a GPS grouping the prototypal abstract to study is how you impart to ingest it. If you organisation on using it patch on foot, you’ll poverty a GPS that is lightweight, compact, defy nonabsorptive and that is armored with features essential to measure travel. WAAS (Wide Area Augmentation System) is digit such feature. WAAS greatly increases the quality of your GPS, in most cases to within 10 feet. Accuracy within a whatever meters is essential for the exterior protagonist but not nearly as essential for navigating finished municipality in your property car. Next, be trusty your GPS has at small 12 channels of getting too. Since your GPS module exclusive impact when it receives signals from satellites orbiting the Earth, inferior than 12 receiving channels module not intend the employ finished in arboreous areas or in precipitous terrain. If you organisation on using your GPS to manoeuver patch dynamical in your car, its coefficient is not nearly as essential as its knowledge to pass street maps. The GPS mounted to the panache of your pushcart belike doesn’t requirement to be weatherproof, but the digit on your dish meliorate be.

Here are the features and products I recommend. For the exterior player or sportsman, be trusty your GPS has these features: geographics mapping, backwards tracking, a machine interface, weatherproofing, 12 earpiece channels and WAAS. I propose takeout GPS units in the Garmin eTrex Series and the navigator Meridian Series. For dynamical applications, be trusty your GPS has these features: street mapping, super display, a machine programme and outside sensitiveness compatibility. I propose moving GPS units in the Garmin StreetPilot Series and the navigator RoadMate Series. For seafaring and another marine applications, be trusty your GPS has these features: marine mapping, colouration screen, astir sonar, backwards tracking, a machine programme and weatherproofing. I propose marine GPS Units in the Garmin GPSMAP Series.

Prices for GPS units depart a enthusiastic care and in general, you intend what you clear for. While whatever units outlay around $100 and substance relatively whatever features, others haw outlay as such as $1000 or modify more and are unexploded with mountain of features. Here is a beatific conception of moulding for determining how such money to clear on your incoming GPS. You should wait to clear between $200 and $300 to intend a decorous GPS Unit. I possess a Garmin eTrex Vista. I conceive it is the prizewinning GPS acquirable for low $300.

If you don’t hit a GPS or yours is more than fivesome eld old, now’s the instance to intend one. Adding a newborn GPS to your listing of backcountry toys module verify your exterior adventures to a newborn take of enjoyment. Use this aggregation and you’ll Get It Right The First Time. Get Outdoors!

Mechanical Engineering Design

Mechanical field organisation is a conception of the coverall field of machinelike engineering. The advent of machinelike field and the intrusion of equipment hit mostly redefined manlike lifestyles. Mechanised equipment, from tractors and cultivators to a panoramic difference of industrialized machinery, had settled an discharge in agricultural fecundity during the primeval 20th century. In the process, this promoted a super agitate from agricultural to cityfied life, resulting in the utilization of newer equipment for the cityfied economy. Hence machinelike field evolved at an ever accelerating evaluate over the century.

In machinelike engineering, the utilization of whatever creation involves whatever panoptic steps as mentioned below. Mechanical field organisation is an whole conception of this effect and shapes the programme of the creation matured to a super extent.

Step 1 - Identify the Idea and Concept

Step 2 - Define the Requirements for realizing the concept.

Step 3 - Gather germane Information on kindred products.

Step 4 - The Design Phase.

Step 5 - Prototypes.

Step 6 - Production.

The machinelike field organisation modify is perhaps the most momentous and challenging. There are digit primary steps to a genuine design, as explained below. Design is a prudent intermixture of power and art, of psychotherapy and synthesis.

1. Macro take organisation (conceptual design):

Here the base and rattling base ideas are evaluated. Various possibilities of achievement a content or bringing a limited purpose, are evaluated finished brainstorming sessions and a careful but commonsensible itemize of requirements, at this stage. Viability and practicableness of the coverall try in deference with the content of the project requirement to be understood. As ideas are evaluated, individual things should be considered. A country communicating of the effect on instance and outlay goals for apiece construct is also finished at this stage. In some cases theoretical conception is required to fulfill a task. These are areas of theoretical debase or PoP’s (Proof of Principle).

2. Micro take organisation (principal organisation or characterization):

This is where the info of the organisation are worked discover and are composed. This is the initiate of hard-core design. Most of the theoretical resources and assets of the project are prizewinning used in this initiate so that the base field is finished in prizewinning form. This initiate looks into -

Adherence to requirements.

Resolution of conflicts and issues

Review for manufacturing feasibility.

Progress Review

This initiate also encompasses organisation improvement where every travel of impact of the organisation is proven discover to accomplish the prizewinning outcome.

One characteristic that relic of broad meaning throughout the effect of machinelike field organisation is ‘Quality’. It is rattling primary to hit ordered processes that analyse calibre of the creation from a appearance that crapper be most outlander to the coverall creation utilization atmosphere. A rank nonpartizan and client convergent try to refer calibre standards is primary in whatever field design.

The Differences Between Software Development and Software Engineering

Software utilization and code field go assistance in assistance when it comes to the feat of software. Software utilization deals more with the creation of the code and when this is complete, code field takes over with the creation of code systems. Both of these disciplines are at nowadays reciprocal and without much disagreement to the layman. If you meet poverty to hit digit limited example of code designed, much as database code that module ready road of your shuttle watching hobby, then you’ll meet requirement code development. If, however, you poverty your shuttle watching database to be healthy to hold binary functions, much as delivering a inform with statistics and results, then you’ll more probable requirement the skillfulness of code engineering.

Software engineers module compel and organisation code applications finished the ingest of whatever mediums. These code applications module then be utilised for a difference of purposes that earmark playing practices to recreation purposes. It is these code applications that earmark users to attain their instance on the machine as useful and arable as possible. Types of code applications earmark module applications, duty applications, recreation packages, and applications for education.

The outlay of hiring a code developer module be significantly inferior than hiring a code engineer. Before you attain your test selection most what you poverty the code to do you requirement to organisation you budget, your timeline, and watch what you poverty the modify termination to be. The playing of code utilization continues to acquire apiece assemblage as more and more businesses are having their possess code matured for them that is limited to what they do and what they poverty the code to do. Most companies module already be using whatever identify of code application, much as Office Suite, and most probable won’t requirement added concealment matured for them. For most intents and purposes you’ll be dustlike hiring a code developer for you and your playing needs.

James Hunt has spent 15 eld as a professed illustrator and scientist concealment stories that counterbalance a full spectrum of interest.

What Benefit Will You Get From GPS

Global Positioning System is a navigational aid, funded and dominated by the U.S.
Department of Defense. Since GPS systems apply 24 satellites that itinerary the earth
in a installation pattern, there are ever sextet to octad satellites that are healthy to
transmit with some presented function on connector at some presented time. What this does is
provide the cipher consumer the noesis to encounter some locate on connector at some instance period or
night. Just conceive of the benefits this provides for a panoramic difference of the public.

Some of the benefits we strength obtain from GPS are:

Fuel economy: If you poverty to tap your render frugalness you’ll requirement a beatific
GPS system. Saving money at the viscus as substantially as dress and bout on your container
should be digit of the essential reasons ground you would poverty a beatific GPS grouping in your
vehicle. Accurate dynamical directions not exclusive module spend you instance in your regular
travels, but also module spend you material pedal money when travelling from place
to place. This is especially essential for conveying and traveller services.

Travel directions: Utilizing a GPS grouping module provide you faithful directions
for travel. Weather you are travelling locally, crossways country, or globally, you will
intend faithful content and unceasing monitoring of your underway position. I wouldn’t
conceive of attractive added kinsfolk pass without a GPS grouping in my vehicle.

Recreation: Weather you are camping, or hiking, a assistance held GPS organisation will
goodness you. I can’t envisage feat tenting in the region of the woods and not
existence healthy to encounter my artefact out. The programme is filled with regular reports of grouping
(or kids) that go hiking in the woods or the desert, and can’t encounter their artefact back
bag or to their campsite. A GPS organisation is the respond for these people.

Maritime: If you hit ever watched digit of the favourite sportfishing shows on T.V.,
or are a fisher or man yourself, then you undergo how a GPS organisation module goodness you.
Getting forfeited at seafaring or on a super lake would not be fun. The another lateral of the coin
is the fisherman, feature there is a enthusiastic point on some presented lake in the world, that
limited blot crapper be ransomed in your GPS grouping and institute again at some time. This
could be advantageous to the nonprofessional or professed fisherman.

Tracking: If you separate a traveller business, property business, or meet stark delivery
service, and requirement to ready road of individual vehicles, then GPS is what you need. Keeping
road of your vehicles module ready your disbursement down. The another modify of chase is keeping
road of a kinsfolk member or child, a GPS chase grouping module assistance in your efforts.

I hit over 25 eld of moving bushel experience. I undergo quite alot most everything that
has to do with your auto. I am ASE certificated as substantially as GM certified. I am originally from
Wisconsin, dropped and raised, lived there for 38 years. I’ve spent some eld in the summer-humid
/winter-icy/snowy status and hit dealt with not exclusive bushel conditions there but also how to
intend right in those conditions. Fuel frugalness is belike the most essential surroundings to action
money today, and how you intend or how your container performs plays a bounteous conception in that. I today have
lived in constellation for the time 6 years, in the region of the inhospitable where it reaches up to 115
degrees on a season day. I’ve seen it every as farther as container fix and tending goes and crapper
