VPC Using Program in the Bus

Overview

iBoin- VPC designed by Boanying is a people counter product used for a variety of channels with a higher accuracy counter(95%-98%)which is based on binocular stereo vision technology and intelligent video analysis technology.

VPC has a variety of interface like RJ45, RS232, RS485, USB and GPIO (8+2), and have a lot of connection and using methods. This article will mainly introduce the using and connection method.

Description of the terms

VPC:	Video People Counter, include one or two StereoCamera.
DVR:	Digital Video Recorder
GPS:	Global Position System/td>
GPRS:	General Packet Radio Service
3G:	Short for 3rd Generation，the third generation mobile communication technology, cellular mobile communications technology which support high-speed data transmission. Now there are four kinds of standard 3G:CDMA2000，WCDMA，TD-SCDMA and WiMAX。
WDS:	Wireless Distribution System，that is wireless distributed system. Through router open WDS wireless extend the wireless signal and then covering a broader range. WDS allows wireless bridge through wireless AP or wireless router, and do not affect the other wireless device covering function. So we can use two wireless devices to establish WDS trust and communication relations, so as to extend wireless work coverage twice.

2. 2. The number of records exchange method：
   1)?VPC initiative sending
   VPC send every record to DVR or GPS through serial port, then DVR or GPS sending the record to stage software through GRPS/3G.
   2)?VPCpassivity respond
   DVR or GPS sends command to VPC via serial port and ask for part or all records. When VPC received the command and then respond right now.
3. Video
   VPC can combination two binocular stereo camera sto a 4-way video image, through video wire using analog signal output video to DVR, then recording.

1.2.2 Background software connection

GPS/DVR server platform software achieves the VPC record via fixed IP and stored in its own database, and statistical and search passenger information using self-developed software reports.

2 Send records through GPS/DVR using database interact records

2.2.1?Device connection in the bus

1. Hardware connection
   VPC serial port（RS232/RS485 optional）connect to DVR or GPS that with GPRS/3G.
2. The number of records exchange method：
   1)?VPC initiative sending
   VPC send every record to DVR or GPS through serial port, then DVR or GPS sending the record to stage software through GRPS/3G.
   2)?VPC passivity respond
   DVR or GPS sends command to VPC via serial port and ask for part or all records. When VPC received the command and then respond right now.
3. Video
   VPC can combination two binocular stereo cameras to a 4-way video image, through video wire using analog signal output video to DVR, then recording.

2.2.2 Background software connection—database interact

GPS/DVR server platform get the VPC record through fixed IP, and stored the passenger record data to its own database and open to iBoin-VPC-Server.exe, and copy it to the traffic statistics database, then use iBoin-PC-Report.exe statistic and search the passenger information.

3 Send record using TCP/IP through GPS/DVR

3.1 Device connection and data flow chart

3.2 Connection

3.2.1 Device connection in the bus

1. Hardware connection
   VPC serial port（RS232/RS485 optional）connect to DVR or GPS that with GPRS/3G.
2. 2. The number of records exchange method：
   1)?VPC initiative sending
   VPC send every record to DVR or GPS through serial port, then DVR or GPS sending the record to stage software through GRPS/3G.
   2)VPC passivity respond
   DVR or GPS sends command to VPC via serial port and ask for part or all records. When VPC received the command and then respond right now.
3. Video
   VPC can combination two binocular stereo cameras to a 4-way video image, through video wire using analog signal output video to DVR, then recording.

3.2.2 Platform software connection

GPS/DVR server platform get the VPC record through fixed IP, and stored the passenger record data to its own database and open to iBoin-VPC-Server.exe, and copy it to the traffic statistics database, then use iBoin-PC-Report.exe statistic and search the passenger information.

4 Send record via its own GGM module

4.1 Device connection and data chart flow

4.2 Connection

1. The number transfer
   VPC use GPRS/GPS module sending records to iBoin-VPC-Client with fixed IP via GSM. iBoin-VPC- Server.exe server software will right it to database. Again statistic and search passenger information using iBoin-PC-Report.exe
2. Video
   VPC can combination two binocular stereo cameras to a 4-way video image, through video wire using analog signal output video to DVR, then recording.

5 Send records via wireless LAN(WIFI)（WIFI router cascade）

5.1 Device connect and data flow chart

5.2 Connection

1. Install wireless router on bus
   One-way or 4-way router with WDS function,（WDS, that is Wireless Distribution System，Wireless distributed system）, link to VPC via network cable.
2. Passenger records transfer
   When the bus traveling outside the station, passenger get on and off, the records will stored in flash of VPC, you can save 1311072 records.
   When bus traveling inside the station, the WIFI router on bus will connect to the WIFI router of station automatically, and connect to iBoin-VPC-Server.exe. Then send the records had not been sent to sever to database, you can statistic and search the passenger information via iBoin-PC-Report.exe.
3. Video（Option））
   VPC can combination the two binocular cameras 4-way video image to one four –segmented image, through video wire output to DVR using imitate signal and record it. Also can connect it use WIFI and download to the computer.

6 Sending records through wired LAN

6.1 Device connection and data flow chart

6.2 Connection

1. Router
   Connect all VPC to router or switch to make the server and VPC in the same LAN and each VPC has its own IP.
2. Passenger record transfer
   When people pass through each binocular camera, it will write record in the counter and store in the flash of VPC. At the same time,, it will send to iBoin-VPC-Sever.exe automatically, you can statistic and search the passenger information via iBoin-PC-Report.exe.
   If network is impassability or server can’t connect to VPC. Each VPC can save 131072 records off-line, and when the network is connectivity, VPC will send to all the records that had not been send to server.
3. Video（Optional）
   Each VPC can combination the two binocular cameras 4-way video image to one four –segmented image, through video wire output to DVR using imitate signal and record it.
