11. SMS IN OUR PROJECT

12. C ONNECT SMS TO MCU F-Bus -full duplex -Runs at bit rate of 115,200 bps. Type of connection M-Bus -half duplex -Runs at bit rate of 9600 bps.

13. AT COMMAND commands are the application layer of MBUS or FBUS commands AT commands work on devices that have a built- in GSM modem

14. AT COMMAND V S. F-B US Send message AT command AT+CMGS 972599378166 F-Bus

15. S O WHY F-B US F-Bus work with all kind of mobile devices especially old devices. AT commands don’t work with devices that don’t have built in GSM modem.

16. M ICROCONTROLLER PIC18F4550

17. M ICROCONTROLLER PROGRAM Receive Message: Transfer order to central PIC Check sender number If correct get order from message store message frameWait until message receivesynchronize the USART in the phone with microcontroller

18. S END M ESSAGE Send message Transfer input to mobile through F-Bus If input change, change message frame according to number of input Monitoring incoming data from central PIC

19. C ONTROL REMOTE DEVICES OUTPUT

20. M ONITORING REMOTE UNIT INPUT

22. N ETWORK SUPPORT IN OUR SYSTEM First time to support stand alone Ethernet. No software needed to run the system. No extra hardware to connect with PC. Flexibility. Very short start up time. Can be improved to connect to the internet.

23. E THERNET MODULE A RCHITECTURE

24. PC NEEDS NIC AND PIC NEEDS ENC

25. ENC 28 J 60 A DVANTAGES Supporting 10base_T 10 Mbps speed. Simpler interfacing with Microcontroller. connectable via SPI. Need only 5 pins to connect with PIC. Attractive price.

26. M ICROCONTROLLER OF MODULE Pic18F452 is installed. Full support for SPI module. Sufficient ram space. support enough speed for its duty.

27. WEB P AGE PROGRAMMING WEB page is programmed as HTML code. Html code is saved in MCU as characters array in PIC Memory. The code Can be edited in the MCU to meet the coming request.

32. C ONTROL OPERATION Step 2 Step 3 Step 4 Step 1 Sending control order ON/OFF Change the state of the output port Modify the HTML page Return modified page

33. M ONITORING OPERATION Refreshing the value of input. Auto refresh in the web page. Changing the unit color if input status is changed.

34. C ONNECTING WITH INTERNET What we need ? Public IP address. Web-server with known IP. Reliable security.

35. Wireless Block

36. W HY WIRELESS ? 1- Easy to deploy. 2- Easy to distribute. 3- No infrastructure required.

37. W IRELESS B LOCK

38. W IRELESS CONTROLLER The encoder and decoder are used in interfacing the TX and RX to the MCU and in addressing different devices.

39. R EMOTE DEVICE

40. A DDRESSING The Encoder allows address assignment. Each device has its own address.

41. I NTERFERENCE Interference occurs since the channel is a half duplex

42. S ENDING C ONTROL DATA Control data

43. R EQUESTING MONITORING DATA Monitoring data

45. C ENTRAL B LOCK

46. I NTRODUCTION Task: - To get the other blocks working all together. - To organize the flow of data among blocks. Features: - The heart of the system. - Acts like Master while the other PICs act like slaves.

47. H ARDWARE C ONNECTION

48. W AREHOUSE A PPROACH Main Concept: - Using the Central PIC as a warehouse. - Whenever a block has data to deliver or needs data, it stores it in or takes it from the warehouse. - Each block has its own functionality and its own manner in requesting data.

49. T YPES OF C ONNECTION Two types of connection are used: 1- Parallel Connection: To connect the Central PIC to the SMS PIC. 2- USART module: To connect the Central PIC to both, the Wireless PIC and the Ethernet PIC.

50. B USY L INE Other blocks may communicate with the Central Block at the same time. Busy line is used to indicate that the Central PIC is in the middle of a session with one of the PICs.

51. P ARALLEL C ONNECTION It consists of 10 lines, two way 8-pin data port and two control lines.

52. USART O PERATION Wireless PIC & Ethernet PICs share the Central PIC’s RX. Connecting them together causes interference. AND gate is used for isolation.

53. USART O PERATION N UMBER The Central PIC receives data from both Ethernet and Wireless PICs but can’t recognize from which one. USART Operation Number is used which upon it the Central PIC determines the source of the data.

54. R ESULTS The system was successfully designed and implemented. The system was successfully operated using SMS. It sent feedback SMS on the user number indicating changes in Inputs. The system was successfully operated on a Local Network by accessing its HTML page.

55. C ONCLUSION Nothing such as PERFECTION. (No ideal System). More work should be done. Block approach allows upgrading and improvement. Many improvements crossed our mind.

56. F UTURE W ORK Supporting dynamic IP addressing that allows the system to adapt to different LANs without the need to pre-define the Network. Connecting the system to the Internet and allowing wider range of monitoring and control. Developing a mobile phone application making monitoring and control using SMS an easier task.

57. F UTURE W ORK Implementing dynamic allocation of Remote Devices allowing a larger number of Remote Devices to be installed easily. Adding storage devices and creating data base for operation history. Interfacing our system to other devices such as Programming Logic Controllers (PLCs), Soft Starters and other systems allowing more complex operations.
