3. Motivation Graduation work Historical Background
Total system combined human and unmanned security has been begun in the 90’s.
Before that, some equipment like CCTV had been used but these days, cutting-edge computer communication equipment is being used in security.
사람에 의한 인력경비 사업에 첨단 시스템 장비가 도입돼 경비의 과학화가시작됐고 90년대 들어서는 인력경비와 무인경비가 결합된 토털시스템 경비가본격화됐다. 그 이전에도 폐쇄회로(CC TV)와 같은 장비들이 동원되기는 했지만 이때부터는 중앙관제 출입통제 원격감시 등 모든 분야에 최첨단 컴퓨터 통신장비들이 활용되기 시작됐다.

4. Motivation Graduation work Why the Project is Required
Guards can patrol even blind spot of CCTV using this vehicle without getting around.
It is going to help them to work efficiently when they have a lot of things to do.
특히 야간에 경비원이 자리를 비우지 않고 순찰을 할 수 있으며 다른 업무에 지장이 없도록 할 수 있다.
CCTV의 사각지대를 정찰 할 수 있다.

5. Theoretical Background
Graduation work
1. Smart phone connects to vehicle using Bluetooth and drive remotely
2. Sense obstacle and
avoid it automatically
3. Monitor the screen using camera equipped with vehicle
차량의 구동은 블루투스를 이용하여 앞뒤 좌우로 움직인다.
카메라와 연동하여 차량을 원격조정하게 한다.
초음파센서를 이용하여 주파수를 송신하고 수신된 주파수로 거리를 계산하여 장애물을 피하거나 정지 하게한다.
거리는 짧으나 감지 폭이 넓어서 초음파센서를 선택하였다.
차량이 지나간 경로를 휴대폰으로 확인한다.
4. Check where vehicle is by using NFC and display map

6. Theoretical Background
Graduation work
Principle of Ultra sound sensor
Send trigger signal to SIG pin.
Module sends 40KHz pulse when trigger signal receive.
Check echo signal until coming after reflected.
MCU send echo signal about distance to obstacles.
MCU calculates the distance by coding.
초음파 센서 구동 원리
SIG 핀에 트리거 신호를 준다
트리거 신호가 오면 모듈은 40khz로 펄스를 보내고
물체에 반사되어 올때까지 에코신호를 체크한다
MCU에서 물체거리에 대한 에코신호를 보낸다
MCU에서 코딩을 통해 거리를 계산
trig 핀을 통해 펄스를 인가하면 초음파 센서는 8개의 펄스를 발생
시키고 측정된 거리에따라 Echo 핀을 통해 출력시킨다.
Echo핀 출력시간(us)/58 = 거리(cm)
장애물이 없다면 38ms의 펄스를 Echo핀을 통해 발생시킨다.

7. Theoretical Background
Graduation work
Mapping using NFC or QR code
Check the way of vehicle

8. Problem & Goal Statement
Graduation work
Problem Statement
Security cannot work others when they have to patrol.
Crime may be happened in blind spot of CCTV.
Goal Statement
We are going to make Vehicle to avoid obstacle by itself patrolling by controlling remotely while watching the screen received by camera to decrease trouble of guards and danger in blind spot of CCTV.
Display the route in a phone.
Problem S
경비원이 직접 순찰을 하여야 하는 수고가 있었다.
CCTV의 사각지대에서의 범죄가 일어날 수 있었다.
Goal S
충돌을 방지하는 원격조정을 하는 차량을 구동시켜 수신된 화면으로 감시를 한다.

14. Risk Management Graduation work Schedule
It will be postponed unless some parts are delivered in time.
Budget
we will need additional expense if some parts break down.
Goal
It is hard to make code to add some functions.
Wrong distance expectation for obstacle sensor.
Distance of Bluetooth communication is limited to control remotely.
