Supermarket temperature Alarm Monitoring Over The www.

[Mark]

Hi All

Alarm monitoring and case and coldroom performance history is available on line.
I know of a few stores that participate, and have used this option.
Is this application used around the world?

Regards Mark

[Mark]

Hi penguinkiller
Was it purely monitoring or could remote changes be carried out?.

hi mark,

I dont do supermarkets but I look after big dairies.

from a laptop + mobile phone via the web, me or anyone with the relevent software and password, can check every parameter, history, alarms, changing parameters,reseteng alarms.etc. etc.

the software is made specialy by the company that does all the controls.

several companies in israel are doing it.

its very cnvenient , friendly and easy to use.

I'm sure its the same as in supermarkets - differenrt language though.

Good Points
You can dial in and check alarms and save a trip to a faulty probe at 2am when it could have waited to 8am.


BAD POINT !!!!!!!!!!!!
Managers (Site & Company) UNTRAINED can also dial in and find nothing jobs for you to look at when you could be doing more important jobs.

Like Mobile phones, Trackers, Automatic Attendence systems it's modern technology and eventually it will come in.
Hopefully only to large sites for a few years as yet & hopefully access only given to people who fully understand what the sytem is saying

[chemi-cool]

what about using a password only for authorized techs and a log of who loged in and when.

this can save some problems.

Certainly the application i was refering to is only accesible with appropriate passwords and software,
And is only authorized to regional supervisors,certain senior engineers and service personel monitoring alarms.

please read what grabber01 wrote and you will get my point.

Danger - Will Robinson!

I was at an industry information night the other month and one of the presenters was flogging his Interent accessable controllers and he put up a slide full of Internet acronyms, such as SMTP, SNMP, SSH ...., and said that the banks use this technology, and that his company uses this technology - therefore his technology was as safe as a bank. The fact that no one else in the room had to stifle a laugh showed me just how dangerous this stuff is to those who don't understand it.

The Internet was built by the US military and Academia who had no interest in security, billing or authenication. Riff raff were not permitted. It was not designed for the great unwashed.

It's a bit like CB radio. Our British friends might have missed out, but the Australian experience was like that in the US where there was a great CB radio boom with shops opening everywhere and every second car getting one installed. The riff raff soon made it unusable and we had to wait for cellular/mobile phone networks to fulfill the CB radio dream - wireless communications for all.

The Internet is a great tool. However, it has been oversold and most users have no idea of the vulnerabilites. Just the fact that war drivers still find 30% of wi-fi networks with open access should give you a clue.

Often the cost of securing a network exceeds the value gained by allowing remote access. The trusting or unlucky will come unstuck in a big way. Take care and get expert advice - don't trust the vendor.

[Mark]

Hi baker

Any system over the www is open to abuse,However what i was refering to is just monitoring and case history, graphs etc open to engineers .

Remote changes in my opinion should not be allowed only configuration by software companies,even then notification to relevant people should take place.

Regards Mark

[grabber01]

I have got to aggree with Mark, Remote access for monitoring, downloading is fine but NO WAY should remote changes be allowed to parameters. Security it upmost when you condider that damage that could be done. Hackers/Kids do not take long to work out passwords/Codes (How many of you use wife/Childs name as your'e password for this site). Just because someone logs on it does not prove it is actually them making the changes. At least on site someone is there and can see who's chaning things.

I know CPC USA has a central monitoring centre for their customers, Danfoss USA also has the same but I know they monitor other brands of controls as well. No supermarket chains in Oz use these monitoring centres, I don't know of any set up in Oz either.
Can't really see them going for it, if anything, both majors over here have their own maintenance call centres, they would probably incorporate monitoring into these call centres.
All stores still have dial in facility, and what a godsend it is (in the right hands) but they choose not to use the dial out facility. Instead they switch an output on an alarm condition which open circuits a channel on their building security alarm, which is centrally monitored, all alarms show up as a generic refrigeration alarm and the store is contacted by phone by the alarm company, their are also flashing red lights in office and shopfloor to notify staff.

Hi 750 valve

Yes ,I get what your saying in some supermarkets much the same over here .What i was reffering to is a function available to service personnel/engineers in the office or at home to pull out graphs and tables on certain cases say look at how many defrosts?,what temperature the probe /cabinet reached ?,when it alarmed?what the probes are reading or indicating?.To if possible cut down on out of hours/weekend alarms ,say a frozen food well case ices up for whatever reason the matter could be picked up on at a earlier stage and the call covered in normal working hours ,(What ever normal working hours are in supermarket refrigeration)

I believe this would benefit everyone Plant alarms etc should be covered as soon as possible.

Regards Mark

[750 Valve]

Yeah our on call guys have a lap top, mainly to save on pain in the arse calls miles from home, they can check the graphing to determine if it is a real problem or just case loading, etc.
On site all controllers used have the ability to display graphs and logs and I'd expect service mechanics to use these to aid their repair and gather info.
We dial in and check things from our office, not as preventative as it could be though, usually just to prioritise calls or get graphs of new or refurb sites to present to customers, or sometimes to prove our way out of stock losses!
Usually all of our racks are controlled electronically, with LP and HP controls for safety only. One major over here specs case controllers (AKV pulse) or standard txv and EEPR, so naturally with case controllers you can get even more info on the screen (coil in, out, etc.) Other than that temp and defrost control is by central microprocessor (CPC, Danfoss,etc) or good old microm RCU12's.
Customers quite frequently dial in to sites, maintenance supervisors usually checking on nuisance sites, or one major has a bloke who dials into EVERY site and checks EVERY meat case disch air temp and product sim temp EVERY week. If they're not cold enough he'll let you know. Same chain has another bloke who dials in and checks power consumption, needless to say these two provide some wonderful scenario's, cases have to be colder says mr temp, racks have to draw less power says mr accountant.

[tonydeith]

Hi all


RDM have a central monitoring office in Glasgow,staffed by refrigeration engineers. Who monitor various stores in the uk,the idea being that they can anticipate a problem in the store before the customer loses product in the store and to cut down callouts to the service provider.So if the contract is on a pay per call basis there is supposed to be less wasted calls to the service provider thus saving the enduser bags of dosh!!!. Other companies used to switch off their shopfloor alarms at 8pm,responding to plant and coldrooms{if only}. Central monitoring is a good idea,but the customer still prefers to see someone with a pulse on site,rather than deffering it till the morning.Though some that i know do nothing but deffer calls till the morning.

In a dream system...

There would be zoomable floor plans showing refrigerated cases. There would be no limits on the number of users. Each user would be allowed to do only specific things on the system. You would switch from refrigeration to hvac on a single click. Refrigeration stuff would go away, and hvac stuff would appear on the floor plan. There would be modes of operations. In the least powerful mode, the software would talk the language of mister manager. In maintenance mode, it would talk our language. In configuration mode, we could add new sensors, new cases, compressors, etc. There would be a log of who did what and when. For the past 3 years. Every single setpoint change would be logged. And you could access a 24 hours graph of any temperature, pressure, humidity, compressor state (on/off), etc in a single click. For the past 3 years. An alarm bar would show alarms from all subsystems. Clicking on an alarm would position the graph at the precise moment in time when the alarm was generated. There would be no nuisance alarms, just true refrigeration alarms. Trending would allow me to overlap up to 7 graphs. Alarms would trigger a local buzzer, flashing lights or alarm relay panel. Alarms would also be sent on numerical or alphanumerical pagers and on emails. Hey, people might even be able to receive their emails on their cell phones. There would be plenty of reports and troublesshooting tools. We would see the rach defrost schedules in one screen, showing the peak load caused by hot-gas defrosts on the rack. If we then could access it through the internet via a chain provided VPN access, then it would be safe too. Isn't that a nice dream?

Fortunately for me, this system exists and I use it. Their web site sucks however. But have a look at www.microthermo.com

[Peter_1]

Do you have some prices of components (pack controller, software, freezer cabinet controller..)?

[oldwolf]

Do you have some prices of components (pack controller, software, freezer cabinet controller..)?

Basically the supermarkets chains here buy direct from Micro Thermo or their boards come already installed on the pack. The only thing I have purchased myself is sensor nodes that read the case air discharge temp and coil outlet temp. They have 8 universal sensor inputs. Cost for that board was around $600 CAN. I have no idea how much the software cost or the other boards.

To control a pack, you need 1 suction pressure controller per suction group, 1 compressor controller per compressor, 1 circuit controller for 5 circuits and 1 controller for the condenser. There is no central controller like ComTrol, danfoss or Einstein.

The cool thing is that all sensor nodes on the floor plan send the case temperatures back to the rack if you use temperature terminated defrosts.

If by freezer cabinet controller you mean a stand-alone merchandiser display case controller, nobody around here uses that. Everything refrigerated in a supermarket is controlled by the packs.

[dill]

penguinkiller, what reasons have they given for taking away this dial in abillity? I worked on js stores when the stores first became electronic and it was a godsend to be able to dial in and asses a problem. I remember one xmas when I got an aux 1 to a store 80 milesaway. I dialled in and found it was short of gas. I stopped at my local office and picked up several large bottles of 22. I got to the store and put the gas in the pack(after reparing the leak) and the store lost no stock. Without dial in this would'nt have been possible and thousands of pounds of produce would have been lost and the shelves would have been empty at the busyest time of the year. dill.

Ok, Im not into supermarket stuff........but is there a facility somewhere, training for instance, where I could dial in and see all of this stuff????

Im like one of those meddlesome blokes.........wanting to know everything !!!!!!

[Peter_1]

The system oldwolf described is almost an exact copy of the Radford system I used in the past.
Can it also monitor NO or NC contacts (overload relays, Oil pressure, opening of doors,...)?

Peter

Hello Peter,

Yes micro thermo can monitor any NO or NC contact. The following items are automatically monitored on a rack: suction pressure, each compressor on/off state, unloader on/off state, safety line switch or oil pressure swicth, compressor over temp switch, each circuit state (ref, defrost, pump down, drip). On the condenser we get: discharge pressure, and the status of each fan (on/off). For the cases, you get air discharge temp, cases coil outlet temp for temperature terminated defrosts, product sensor temp if any, dual temp switch position, cold room door state (open/close). For HVAC there is: fan status, number of cooling coils on, nb heating coils on, supply air temp, return air temp, mixed air temp, damper positions. For lighting there is: group state (on/off), photocell readings, occupancy sensors (occupied/unoccupied), wall toggle switches (on/off), etc. List is too long... tired of typing. Basically you can log historical data for anything any electronic board reads or calculates. You also get most equipment runtimes, bypass and overrides.

Never used a Radford system.

RDM monitor for Marks and Spencer in the UK.
Until recently the monitoring units have been dialling out via the telephone line.
Recently the monitor is being connected straight onto M&S's tcp/ip backbone along with the tills and re-ordering.
RDM monitors and investigates the alarms and calls out an engineer as required.
4 hours call out for a probe fault is a bit stupid though.

The system works on both RS485 comms and CAT5 through an IP module.

Unfortunately as enigineers or even commissioning engineers - due to the system being bundled onto their main IT system they will not let us get remote access to the stores.

There is no need for any specialised software for your pc - it just runs through internet explorer.

Hey, a screen capture from work on that subject. Using my browser to connect to a supermarket. Firewall let's only our a few service companies through. I have hidden the internet address on purpose. Don't want to get into trouble. This is Rack A, circuit 16, 3rd case (C). A point every minute for a few days. Find it useful and fast. Wish all stores we service had that. Hope this works... first time I attach a picture.

The last post to this www thread appear to have been a while ago.

Have any of you had problems with password protected sites since then?

Any good new features that make your it worthwhile that I should ask from my vendor?

[Capt Steve]

Does anyone know of any companies that have the program for monitoring alarms over the web?

[nh3wizard]

At one of our facility's the computer that is tied into the refrigeration system was put on our company server with its own ip address and password protected. It makes it very convenient when there is a problem the operator on site can not handle or figure out, then it dosnt make any difference where I am at, I can get connected and see what is going on and maybe talk the operator through the problem.

It is still monitored through the local alarm company through a phone line, its just a general trouble alarm.

Hope this helps.

Eliwell, Dixell, Carel,...

[yroy]

Does anyone know of any companies that have the program for monitoring alarms over the web?

Ay Ay Captain!

I work for Micro Thermo Technologies. We have a product called the EFM Workstation that can monitor alarms from hundreds of stores from one or more location. It works only with our control products however. Alarms can be viewed from the internet after establishing a VPN connection with the supermarket chain.

[supermarketguy]

Hi All,

Danfoss in the uk are about to install new front ends in a major retailers stores. This system is also IP addessable and can be monitored either by www on a landline or has the facility to use a sim card which connacts via mobile link. This facility is also only open to commissioning personnel at present. this system has been fitted in only a few stores at present.

[ICEUROPE]

There is a new monitoring system by Eliwell which is called televis net. This enables the user to access and remotely manage the coldrooms or a/c via the web using an IP address. for more information contact the eliwell website.

[mambro_01]

Hi All,
I saw the eliwell monitoring system and it is very fleaxible. i got a good feeling with. The latest is achievable also by PDA. As far as i know the product is improving with new features and can work with no eliwell branded controller. I saw one plant working with Ducati energy controller

[mambro_01]

My experience in Italy is with Eliwell monitoring system. Now they have released the possibilty to use the radio frequency communication to achive the computer station without using the cable. I got also a training in Eliwell factory where I improved my knowledge on it. The service has a good quality and often they offer the support on site

[cleanNcold]

I do service on 7 stores for a large retailer that uses this system. They have a central office that monitors the systems. They use a computer on site that performs all refrigeration and defrost tasks and can link to it via the internet. I can only access it by going to the store and entering the password in the interface. From there I can change settings,force defrost, and monitor the whole system. All logs are kept by the company monitors. All I do is call them when I am done with repairs and they record it.

[Dan]

I really do not have a response for many of the replies your original question inspired, Mark.

But the answer is yes. I have many customers who permit me dial up access to their systems. Two major chains have IP accessibility as well as dial up. I am not permitted the IP access, but I am permitted the dial up access. I have another large customer who does not permit access, but has IP accessibility for their central monitoring. I am frustrated that I do not have access to their system, but it is their call.

The customers who permit me to access their refrigeration systems are the ones who save the most money on service and are the most profitable for me. I can trend refrigerant levels, assist a technician working on the sales floor while the machinery is on the roof, etc.

It is a waste of technology when the servicing company is not privy to the computers controlling the refrigeration equipment.

[Timsutton2]

Anything that helps you do your job better and is cost effective is an advantage to you. Usually the techs that are not onboard with these new monitoring and controls are not able to understand their value added to the company they are employed by and the savings in labor that these tools save their customer and the overtime to repair emergency afterhour calls.

Dear All

Having been loosely following this thread now for several years I wanted to post a reply and hopefully a cheeky url.

It seems, from the way the replies are going now to the recent resumption of this thread, that many of you are still not seeing the development, from others, in remote access/control that were discussed back in 2004/5 in this very thread.

I am one of the team of field engineers working for Radford Control Systems, throughout the UK and Eurpoe, and as was mentioned after the "Dream System" post previously, our proprietary system did then everything you wanted it to. Since then they have also added a number of other functions like alarm notification via e-mail instead of phone line/dialout and ip addressable controllers. Recently we have been installing variable trim control into glass door fronted cases as an energy saving measure, which is not without it's teething troubles, but is on the whole going well.

We do have some competition from a certain well known gas detection company, but having now had the chance to see their system "in the wild"; play with it; and talk to it's new users; it was well sold. And in a lot of their installations simply "piggy backs" and uses our already installed system's available XML output over the web to generate a text and e-mail based "picture" of what our graphical system is displaying on site anyway. Many of the fridge engineers I meet have admitted to me that they prefered our now "superceded" systems as they were much more accessable and user friendly.

Whilst it is probably shameless self promotion or something to post our website, I can't find it anywhere else.

I submit it on the grounds that it has been properly referenced by others, here, and they still can't get all that they want from there supermarket monitoring all this time later. I trust if it is removed, it will be removed to a suitable location and linked. I am happy to answer privately any other questions, if this thread is not the appropriate place.

Iam sure with your experience, the contributions to the forum will be more than promoting Radford products.

[tranquanghvac]

In Vietnam we use EC2 or EC3 series controller of Emerson for supermarket. It is very easy to use, support controlling via computer and TCP/IP network, logging events and many more. You can use them for cold storage system. Password protection for parameters adjustment. You can control your system via Internet by using "logmein" websoft. Any details, look in www.ecopeland.com

[Steve]

By a curious twist of fate Radford Control systems (RCS) and Micro Thermo are both owned by Carrier (as is Linde). So they are closer to being partners rather than competitors !

I currently install a Danfoss control system into a wholesale retailers. Danfoss dial into the store every 4 hours and publish the data onto a password protected web site for the store (and anybody elese with a password) to review. It can do graphs, alarms, energy consumption and zoom into individual fixtures.

Through the AKM software we can dial directly into the network to make any adjustments etc.

Bit of a halfway house soloution but it works for them though !
