Arduino control software

We want to make a software able to use an Arduino 2560 mega with ethernet shield. We will setup and control 2-6 power generators (or battery packs). We must be able to turn off and on anyone of the 2-6 gensets and control their operation and fuel consumption. We will operate the gensets according to a weekly time plan which we will be able to change anytime. The application will also control 2 cameras and we must be able to Access it and control the gensets from anywhere with a tablet via Internet. The application will communicate with the administrator and the manufacturer for any malfunction, for fueling, and for daily report. It will measure the output and will calculate fuel consumption. The Software will have 3 main procedures 1) Manufacturer. We will setup all the gensets and make data entry of the service needs (hours of use and service description) of each genset 2) Administrator. We will preprogram the weekly time plan and set email addresses where the software will communicate and time of communication. 3) User. We will monitor the 2-6 gensets and 1-2 battery packs while they work. Anytime some gensets will work and some other will not work. We will monitor the fuel consumption, the power output and temperature of oil in some cases. ----------------- We will do some work for you and we will provide you 1) the screens for the GUI you will need but you could change them if you decide to be more ergonomic. 2) the flow charts of all the 3 procedures of the program or the screen and what every option does (in order for you to make the source of each button and window of the screen. 3) Detailed informations about the hardware (relays and power relays, digital fuel pump, amp meters and digital thermometers) and source code showing how you will read their values. ---- We will need maximum 40 pins (mixed outputs and inputs) ----- ARDUINO 2560 outputs and inputs we need (8 outputs) pin 1-8 = +12V output for signal relays (8 inputs) pin 9-16 = 5V analogue input 0 - 0.075Volt for 0-100Amp current (count every 0.1sec) 100Amp shunt [login to view URL] 380889943534?pt=LH_DefaultDomain_0&hash=item58aecf4dee (4 inputs) pin 17-20 = 5V pulse input count (fuel consumption) flow meter1= tank1 flow meter2= tank2 flow meter3= tank1 load flow meter4= tank2 load Fuel flow meter 0-10LPM [login to view URL] 301456117151?pt=LH_DefaultDomain_0&hash=item46302f4d9f (1 input) pin 21 = +12V output for future use (3 inputs) pin 22-24 = +5V analogue input for temperature sensor (16 outputs) pin 25 - 40 = +12V outputs for 100Amps power relays 3phase power relay [login to view URL] 300686559360?pt=LH_DefaultDomain_0&hash=item460250c880 or 1phase power relay [login to view URL] 400570437227?pt=LH_DefaultDomain_0&hash=item5d43dbce6b ============== The software must be able to detect the position of the genset, and to communicate wireless via internet. Actually it will be a web-site.
