Excellent lecture, , I am using vera3 Zwave sysem

Iron

good presentation very interesting topic.

 

Iron

Thank you Jon for the wonderful info

Platinum

What about a fail proof sensors feeding data to controling units at critical to life enviroment/s? Making sure that all of it is working may drive some costs up and that could negatively impact the concept of fully automated system. 

I've loved this stuff since I was a kid!

Iron

Just catching up. Interesting discussions below!

Iron

I agree with Jon. Hotel rooms are probably the best applications for this kind of automatic control.

Thank you.

Iron

Good session, thanks Jon

Iron

Thanks for a good presentation Jon :)

Iron

technology can prevent all, but the user is a proble in most cases...

Thanks Jon, and thanks to all of you for attending.

Blogger

Thanks all -- I will try not to get ahead of myself tomorrow. Less coffee.. :)

 

 

Iron

According to the 2005 census report there were approx. 47,835 shopping malls or strip malls in the USA.


In addition, think of all the hotel rooms where people leave AC or heat on, lights on, etc. If the building knows you are in it, it can turn these things on.

Iron

Good examples -- Remote notification of:  Flood / leak detection, excess humidity level
alarm, gas detection with local intelligence to take corrective action and auto
calling to emergency contacts.  Remote entry control and monitoring.

 

If our technology can prevent losses, it has paid for itself. Eliminating one pipe freeze event can save huge money and prevent mold. Notifying us that our toilet valve is stuck on can prevent the costly need for a new septic.

 

This is how to make people aware that it's not just about green, it's also about taking steps to protect yourself and the things of value.

 

Iron

You are correct that many people have never learned to program their vcr so how are they going to use automation technology, even if it is intuitive.

There are some that will learn how to do one thing and never learn anything else.

But, as designers we can make it easier. For a nickle more, I can use a novram and store preferences rather than have to reprogram things every time power is lost.

We can also choose to have a simpler user interface if we put some thought into it.

Effective speech recogintion will change this too.

 

 

 

Iron

A lot has to do with green technology and an slant toward designing things that are energy efficient.

A big problem is everyone has different needs and issues. You are right, a strip mall may have a shop that uses tons of hot water next to a place that uses a lot of refigeration, next to a place that is just storage. It's not easy to have a unified system that can handle so many issues. And, stores come and go, so it must be able to handle change.

 

Iron

A windmill on a sailboat is kind of an example of energy harvesting. It will reduce forward speed but provide energy. Other types of co generation use pure wasted energy like factory furnace heat which can be used to heat water. 

 

Iron

I had never thought of heat recovery from gray water streams. Good idea.

 

Iron

AC can contribute to EMI. Thats one reason differntial wiring can help reduce sensitiviy to EMI/RFI.

 

 

Iron

Priorities do change from normal situations to extreem situations. That's why a backup  or higher level control point should be able to inject itself into the command stream and override normal functionality.

Iron

A wireless node can use an existing power source like 120 vac. If it is critical it should have battery backup. Many modern small and low power digital radios can even operate for years on non rechargable batteries.

 

A big benefit of wireless is it can go virtually anywhere.

 

Iron

the topic contents as presented by Mr. Jon are all about concerned in ELECTRO-MECHANICAL in building applications...where my job applies...I REALLY APPRECIATES...

Slide 4: I agree device use should be intuitive, but that implies the user knows what the device is capable of. The majority of users just learn enough to use the minimum set of functional capabilities for almost any device. Thnk how many folks never learned how to program the time on their VCR's. Does anyone really know everything their smart phone can do? Intuitive only goes so far. The interface must eventually include two way speech and tutorials.

PE means Professional Engineer

Phase synchronization of power girds is an issue that has not fully been solved. It introduces secondary effects to just switch phases abruptly when bridging two ines with different phases. We need to shif phas angle to control power transfer and direction. This issue will have to be solved.

Iron

Other uses -

Remote notification of:  Flood / leak detection, excess humidity level
alarm, gas detection with local intelligence to take corrective action and auto
calling to emergency contacts.  Remote
entry control and monitoring.

Sorry for the disjoint -- I got ahead of myself. I get excited.....

Iron

We will go into coax tomorrow. It is an interesting medium.

 

Iron

thanks to everybody and see you once again tomorrow...

Most building electrical designers have a P.E. or must work with a P.E., even as a subcontractor ... just sayin' ... These presentations help give a good baseline of the types of issues one must further research and study

Thanks, Looking forward to the next presintation

Iron

really, that's a good contents and would be a reference in my job as well...thanks MR. JON...

exactly, double the current and you are dealing with 4 times the energy loss. IR will drop voltages as well.

 

Iron

Thanks Jon for the presentation.

Iron

Video stream to the children room

Iron

Thanks for the walk thru -- lovely day for a walk through

Nice lecture, with technical Audio issues, but good content!

Iron

Exactly, medical status and alerts should be carrierd with us

 

Iron

Watts up with this --- it Hertz when you do that ...

New Power Grid may not regulate the 60Hz ... Phase Synchronization Issues being critical

http://www.washingtonpost.com/blogs/wonkblog/wp/2013/03/08/surprise-the-u-s-power-grid-is-getting-pricier-less-reliable/

thanks for educating again

good show!

Great lecture all.

Iron

Room temperature is a good example of preferences

 

Iron

Thanks good lecture.

Iron

nice presentation sir, i have reminisced what is my subject in engineering

Jon, thank you for the lecture... but I'm rather disappointed - too many disjoint statements...

Iron

carry on info medical issues?

Iron

It will nice carry your environment preferences as well if you are susceptible to allergies or Info like that!

 

Iron

Thank you Jon for today's lecture

Iron
Location such as Blue Force Tracker
Iron

Room temperature preference

Favorite Radio Stations or Type of music.

 

E = IR : E-VOLTAGE, I-CURRENT DRAWN AND R-RESISTANCE...HEHEHEHE

Question from Jon:

What kind of data and information will follow you from zone to zone, building to building, city to city, etc as your movements are tracked?

Blogger

slide 19 - Jon is talking about personal devices and preferences... the slide is about "structures"... what structures???

Iron

It refer to the losses cause by the reltion between the Current conducted and the Resistance in due the length cable.

 

Iron

Definitely NOT infrared.

Iron

Cghaba: Current times resistance gives the voltage drop acros a load, but the POWER dissipated in that load is given by current SQUARED times resistance. This is a rising parabolic curve relation. Double the current and you are dealing with four times the energy loss.

We're on slide 19

Blogger

i think IR is INFRARED RED LOSS...

V=IR i think he means resistance voltage drops

 

are we still on slide 17 (wireless)? and now jumped into central vs. distributed control???

Iron

IR = Current x Resistance = Voltage

Iron

We're nlow ln slide 18

Blogger

Slide 17 - Why can't wireless use established power source (120VAC) instead of battery or energy harvesting?  It seems most wireless devices today use a wall adapter to get power.... excluding mobile devices of course.

Slide 18 - What are the alternatives to hierarchal control, like can we use a dynamicly scalable priority system that is more nueral rather than strict to get better results.  Priorities change under different circumstances so hierarchial system rarely keep up with the real world demands and priorities that are not linearly scalable in nature.

 

My audio keeps cutting out and I have to go back and hit the "play" area.  Thought you would like to know.

yap, i am wondering also, what does IR means? I am looking at it, but i didn't see in the slides...

But AC can contribute to EMI
Iron

We're now on slide 17

Blogger

We're now on slide 15

Blogger

We're now on slide 14

Blogger

i think on design stage, these must be considered as far as energy conservation is concerned

@Rob - AC instead of DC (Tesla's invention)

Iron

We're now on slide 13.

Blogger

Too many general statements that are not always true...

Iron

when you know low voltage, all of these issues will be resolved.

Question from Jon:

 Instead of using say as 12 V DC wire pair to power a distant node, what can be used that is more efficient?

Blogger

We're now on slide 12.

Iron

i don't have any idea about phantom rob...let me research how is that..

We're now on slide 11.

Blogger

Question from Jon:

Does anyone have an idea as to how much energy phantom loads use in our daily lives?

Blogger

that's right and that is essential in all building applications

We're now on slide 10.

Blogger

Connected smart meters let us see actual instantaneous power costs, letting folks choose to defer running appliances to a lower cost time period.

 

Iron

We're now on slide 9

Blogger

Use impedance matching devices, for example to match the 50 ohm Z of video coax

i think its all about green building applications

We're now on slide 8

Blogger

We're now on slide 7

Blogger

One example would include a wind mill for electric generation on a sail boat

I think before was better, audio automatically ised to start playing at 2:00.

Iron

Heat recovery from gray water streams with counterflow jackets

@Rob - we just recently had a class on energy harvesting...

Iron

Jon's question:

Can anyone think of any co generational functions that can benefit from energy harvesting?

Blogger

@kdavidson - cost would be my guess...

Iron

Why can't you guys use real webinar software? Downloading slide decks and having to click on play to start the audio is so antiquated. I missed the first five minutes because I didn't notice the audio player magically showing up.

Iron

We're now on slide 5.

Blogger

Now Audio is clear.

Iron

We're now on slide four.

Blogger

We're now on slide three.

Blogger

We'rew now on slide two.
