Design of In-Pipe Reliable Leakage Detector

Introduction

[CE 1.1]

Project: Design of In-Pipe Reliable Leakage Detector

Duration: [Date] – [Date]

Location: Deakin University, Australia

Position: Electrical Engineering Student

  1. Background

[CE 1.2]A fairly sizable water amount is lost due to pipes faults and leakages in most water distribution systems. Due to this reason, the leaks individuation is adequate for water resources optimization and rationalization. Thus, the methodologies and techniques which are presently utilized for the leaks individuation, despite the fact considering universally accepted phenomena based on techniques which are accepted currently. These are time-consuming and main need highly experienced personnel. Furthermore, the methods become ineffective and unreliable when conducting measurements in the pipe's specified operational conditions. Thus, the working was done on a wireless sensor network for detecting and locating the issue.

[CE 1.3]The project aim consisted of two units that were placed in a specific difference. I worked on setting the sensor output which kept the same when considering the fact that there was no leakage. In case if there was any difference, it resulted in pipeline leakage and it sent to PC from ZIGBEE which was followed with closing the source valve with DC motor assistance. I controlled the motor with the assistance of the relay.

[CE 1.4] The work activities were predefined in the project and various scenarios were analyzed mainly for getting the targeted work results and achieving the specified results within the defined work tenure. I accomplished all the related project duties under the assistance of the project guide. 

[CE 1.6] Responsibilities:

  • I applied Electrical Engineering expertise for water flow from the flow sensor and output attained from the amplifier to the microcontroller.
  • I executed the signal conditioning unit which assisted well in accepting input signals from the analog sensors.
  • I did a microcontroller transmitter pin connection in the circuit mainly connected for converting 5V input to RS232 level.
  • I utilized a diode rectifier which assisted in providing full-wave rectified voltage mainly resulted in filtering from a simple capacitor filter for dc voltage production.

Title: Multi-way Relay Networks

Duration: [Date] – [Date]

Location: Deakin University, Australia

Position: Electrical Engineering Student

  1. Background

[CE 2.2] Multiple users mainly work for data transmission via relay at the same time in multi-way relay networks. The relay mainly communicates in a bi-directional manner among different users in the pairwise transmission. There is the SNR (signal to noise ratio) penalty without the proper synchronization.

[CE 2.3]The project scope was carrying out error performance investigation in the data transmission among users in the symbol misalignment and phase offset presence. I applied the knowledge for designing appropriate algorithms for improving the performance and investigated the error in the multi-way network. It was of higher significance in data transmission when carrying out performance improvement and error reduction. The appropriate research was made in the entire project tenure specifically for obtaining the targeted project results.

[CE 2.4]The work nature was carrying out an error performance investigation of a multi-way relay network among the user's signal when there was phase offset. I did an error performance investigation of a multi-relay network when there was a user's signal symbol misalignment.

[CE 2.6] My technical responsibilities were:

  • I initialized the work activities with phase offset values variations and mainly noted the considered case results.
  • I did signal decoding at the user end which resulted in implementing the maximum likelihood criterion.
  • I worked on researching the utilization of the user's signal mainly for extraction of the message with own signal subtraction.
  • I worked on plotting the graph with a specified probability function which was linked with one error against the SNR ratio mainly accomplished using engineering skills.

  1. Background

[CE 3.2] The conceptual work is mainly for maintaining time management and carrying out proper scheduling activities. There is a requirement to implement an effective and low-cost automation system. In recent times, the systems mainly developed are based on counting purposes and manual systems. Thus, the GSM module mainly utilized for wireless network creation which is easier to utilize and available readily.

[CE 3.3]The project goal was developing a count system utilizing GSM and RFID technology. I selected RFID technology which was an emerging technology mainly utilized in various applications. I typically did object identification based on RFID technology and it mainly composed of RFID reader and RFID tag. I utilized RFID tags in the RFIS system mainly interrogated from the RFID reader. The work primary goal was based on the identification of data in an automatic manner that was contained in electromagnetic fields. I used the smaller and inexpensive RFID tags and these were for deriving power via RFID reader from the small-signal produced.

  • I conducted research and used electrical engineering knowledge for RFID technology utilization which was an effective way for the identification of objects.
  • I did system execution which was based on wireless control usage and it effectively assisted in system usage for unwired connections.
  • I did RFID reader usage mainly based on RFID tag interrogation.
  • I worked on setting an antenna with the reader for the emission of radio waves and tag responded well in sending the data back appropriately.
