QUOTE (LV_FPGA_SE @ Nov 14 2008, 07:26 PM) No I am not a contractor nor bidding for a project. This is just a self interest. I haven't design the functionality and requirement. I just got this ideas of implementing this system after watching an Airbush crashing documentary in Discovery Channel. If someone can provide me functionality and requirement, i guess i can design it. Anyway, i will take a look and study what are the functionality and requirement. THank for viewing this post Cheer

Hi there, Does anyone here have an ideas on how to implement an Air Crash management System or Aircraft management system using Labview. I am interested of starting a design for this application. Please guide me what tools should I need, is it using compactRIO, FPGA or others? I was watching an air crash video today and throghout the video I realise that most AirBus is using fully computer intergrated to help pilots to control the plane. I was thinking on how Labview can helps in handling things such as Disaster recovery. Any comments and guidance toward this post will really appreciated. Anyway, i am writting a blog at http://programmerresearch.wordpress.com. Have a look and do give me comments about it. Thank you.

If it's a very busy street, a lot of people will want to use it simultaneously when you say that, what do you mean? Do you mean it is not recommend to use race conditions. By the way, may I know whether race condition can use in VISA and serial links?

Can race condition use in serial link? can anyone show me an example of it? My lecturer ask me to investigate?If it work in a serial link i gonna score good mark for it.

QUOTE (TobyD @ Oct 21 2008, 05:07 PM) Lolz..thank you for the interest but can you tell me how am i able to link it to RS-232 using VISA? another thing i need to know what is the disadvantage using Rendzevous and race condition, semaphore? I guess there's too much of global variable?What did you guyz think? Another things is how do you create the control design?

QUOTE (jgcode @ Oct 19 2008, 11:32 PM) Buddy, would you take a look at this Bank.VI zip which have all the bank design. I would like you to explain to me about the architecture. What is redzenvous do? and how the cluster work. This is not my work but i got it though the labview training. Please let me know whether this application can use to my projects and how am i going to put it to serial link, if i were to use this solutions? Secondly, do you know what is the semaphore for? Thirdly, i need you to teach me how to do printing when the customer choose the option to print the balance or the withdrawal slip? what function should I used?

does VISA library work on RS-232? By the way,do you know how to design a cluster with strict typedef? I got Bank.Vi with me where i use Rendezvous, Semaphore and race condition. This is from the labview Basic II course which they ask us to modify a Bank.vi. Through the design, i have no clue on how am i going to put into a serial communication through VISA. Haha=).. i am seating for my CLAD papers soon. So I need to get myself familar with all the basic stuffs.. Anyway, if you were a developer, how are you going to implement this projects? Mind to give me some hints on your state machine or input/output implementation? Sorry for troublesome you. But any help on that will be much appreciated.

You will have 2 PCs connected together by a 9600 baud serial link such that one is the Bank and the other is 4 ATM machines each working independently. The Bank PC has precedent over the ATMs as long as the link is maintained. You will need to work in pairs with one student on each machine. The functionality is as follows Bank PC Holds customer details including Username, Password(encrypted), current balance, overdraft limit, amount over overdraft allowed, Maximum cash removal at one time, Number of times per day transactions allowed. The Amount of money held in each ATM machine and the denomoinations. It synchronises with ATMs regularly. Security checks on selected cards (i.e. log all transactions for the card, including time and date, separately from normal log). Adds & subtracts money to customer account and stops deposits being used for until cleared. Validates the user information by checking input from theA ATM against data held. Limits the maximum amount a machine can pay in a time period.(i.e. if so many payments in sequence are for the maximum amount then set an alarm for that machine.) Keeps credit card for security failure or 3 times wrong password. Runs an audit log of all transactions handled, where from, when, how much or what request. The front panel should allow the current state of each ATM to be displayed, who is logged on and has buttons whose functions are, keep credit card and stop card use. Has data entry functions to allow new customer entry together with starting balances, overdraft limits etc. and a simple default password. There will also be controls that allow the bank to add more money into each ATM and update the synchronisation accordingly Each ATM Will hold an Amount of £5, £10, £20, £50 notes in the machine. Encrypts password. The plain text password is not known to the bank PC only the encrypted version Amount to be withdrawn at a time (£10, £20, £30, £40, £50, £60, £80, £100) The ATM will work out different notes combinations for each amount so that the ATM can continue when some notes run out. When certain amounts can no longer be available then a warning must be displayed. Requests for balance Change password. Slip showing money withdrawn Deposit with receipt. The ATM will respond to a ‘Keep card’ facility on instructions from bank. Each ATM front panel will have enter Username, Enter password and select type of operation functions together with card removed and money taken buttons and money out and message displays. In event of a Communications breakdown the ATM will complete any transaction for a logged on customer and update the bank on restoration of communications How it works Customer puts ID into an ATM followed by Password. Password encrypted and details sent to Bank. Bank either rejects Not recognised, or wrong password or accepts Customer enters type of request Money request – send to bank which replies with maximum allowed varying from 0 – max per transaction or not allowed. An amount of Money is then requested and checked against the limits from the bank. The Money is output in notes available to a money out display (or nothing if out of cash). Card removed button pressed, money removed button pressed. The amount taken is sent to the bank for update of the current balance and the money out display is cleared Balance – send to bank which replies with balance on communications display Change password – enter old password, new password twice(check both are the same) send to bank which checks new is different to old (all encrypted) Deposit - request amount sent to bank and add to balance. The bank will not make this available for withdrawal for a specified time period. <H1 style="MARGIN: 0in 0in 0pt">Communications</H1>The system should be able to cope with the serial link being broken at different stages in the processing without crashing either program. Reconnecting the link should allow the programs continue normally without having to restart and any incomplete transactions to be updated. Based on the above question. I just want to know the implementation for it. I know how to design the ATM. But i have no idea how to put my design into serial link?Please guide me the implementation or give me some hints. Thank you
