  1. SMS & NET Operated Monitoring and Control system By: Mansour Alramlawi MahmoudAlalawi MohammedAlfeqawi JalalAlroumi HamdiJoudeh Supervisor: Dr. HatemElaydi

  2. Introduction • Rapid Growth in technology. • Fields of Industry, Communications, Control, Internet technology ….. And more. • You can be anywhere anytime. You want to know Anything happening everywhere.

  3. One of the Benefits Remote Monitoring & Controlling Home Applications Space Applications Industrial, Natural Resources, Agriculture and others.

  4. Our system

  5. Functionality • As a monitoring & control system for simple applications.

  6. Functionality • As part of a large DCS.

  7. Features PIC MCU Based Stand Alone System SMS & Net Operated Title Blocks Approach

  8. System Block Diagram • Saves time and effort. • Easier to upgrade. • Allows reuse of blocks.

  9. SMS • SMS stands for( Short Message Service). Features of SMS: • 1-can be Sent and Read at Any Time. • 2-can be Sent to an Offline Mobile Phone. • 3-Supported by 100% GSM Mobile Phones .

  10. SMS in our project

  11. Connect SMS to MCU Type of connection • M-Bus • -half duplex • -Runs at bit rate of 9600 bps. • F-Bus • -full duplex • -Runs at bit rate of 115,200 bps.

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

  13. AT command Vs. F-Bus Send message AT command AT+CMGS 972599378166 F-Bus

  14. So why F-Bus • 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.

  15. Microcontroller PIC18F4550

  16. Microcontroller program Receive Message: • Transfer order to central PIC • Check sender number • If correct get order from message • store message frame • Wait until message receive • synchronize the USART in the phone with microcontroller

  17. Send Message 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

  18. Control remote devices output

  19. Monitoring remote unit input

  20. Network 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.

  21. Ethernet module Architecture

  22. PC needs NIC and PIC needs ENC

  23. enc28j60 Advantages • Supporting 10base_T 10 Mbps speed. • Simpler interfacing with Microcontroller. • connectable via SPI. • Need only 5 pins to connect with PIC. • Attractive price.

  24. Microcontroller of module • Pic18F452 is installed. • Full support for SPI module. • Sufficient ram space. • support enough speed for its duty.

  25. WEB Page 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 .

  26. Web page interfacing

  27. Web page interface

  28. Control page

  29. Monitoring page

  30. Control operation Step 1 Step 2 Step 3 Step 4 Sending control order ON/OFF Change the state of the output port Modify the HTML page Return modified page

  31. Monitoring operation • Refreshing the value of input. • Auto refresh in the web page. • Changing the unit color if input status is changed.

  32. Connecting with internet What we need ? • Public IP address. • Web-server with known IP. • Reliable security.

  33. Wireless Block

  34. Why wireless? 1- Easy to deploy. 2- Easy to distribute. 3- No infrastructure required.

  35. Wireless Block

  36. Wireless controller • The encoder and decoder are used in interfacing the TX and RX to the MCU and in addressing different devices.

  37. Remote device

  38. Addressing • The Encoder allows address assignment. • Each device has its own address.

  39. Interference • Interference occurs since the channel is a half duplex

  40. Sending Control data Control data

  41. Requesting monitoring data Monitoring data

  42. Central Block

  43. Introduction • 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.

  44. Hardware Connection

  45. Warehouse Approach • 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.

  46. Types of Connection • 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.

  47. Busy Line • 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.
