Description
First of all, please check below 1 miniute video for our HPC168 automated passenger counter camera for bus, and you can find more details below the video.


HPC168 automated passenger counter camera for bus is widely applied in buses, coaches, metros and other public transportation tool passenger automatic counter application field. It possesses high-performance communication media processor with Hisilicon video purpose hardware acceleration engine. Adopted with main development dual-camera depth algorithm model, it conducts dynamic detection on cross-section, height and movement trajectory of the passenger target, and in turn, obtains comparatively high-precision real-time passenger flow data, providing RS45 or RS485 interface to conduct data interaction and sharing with third-party equipment, which is very convenient for data depth development.

HPC168 automated passenger counter camera for bus can be adjusted from 0-180 degrees, to meet all passenger car environment installation requirements. The built-in wiring method enables perfect integration of HPC168 counter and passenger car environment.

HPC168 automated passenger counter camera for bus adopts integrated design which combines depth camera and calculation main control board, so as to minimize interference factors on camera image information to the lowest level, and possibly to the uttermost decrease construction wiring difficulty level. The one-button debugging mode can quickly complete environmental parameters collection required by HPC168 counter, with no assistance from other equipment terminals.

5. Command Set
5.1 Data Reset
CM:0x12
    LEN:0x00
Upon receiving data reset command, HPC168 counter clears internal counter, and returns to response frame.
e.g. Send data reset command to HPC168 counter with address 0x0001.
STX ID CM LEN DATA1 DATA2 CHK ETX
0x02 0x30 0x300x30 0x31 0x31 0x32 0x30 0x30 0x31 0x33 0x03
 
Response:
Correct response means passenger flow sensor has already executed and completed command contents.
STX ID CM LEN DATA1 DATA2 CHK ETX
0x02 0x30 0x300x30 0x31 0x39 0x32 0x30 0x31 0x30 0x36 0x39 0x41 0x03
 
Error response: (e.g. ID=0002)
STX ID CM LEN DATA1 DATA2 CHK ETX
0x02 0x30 0x300x30 0x32 0x39 0x32
 
0x30 0x31  

Error response means HPC168 Bus Passenger Counter cannot recognize the instruction (packet loss issue) or algorithm internal conflict which leads to inability to complete processing instruction content.
If HPC168 Bus Passenger Counter displays error response, it requests the host computer to resend data, up to 3 times, with interval no less than 1s.
 
5.2 Passenger Flow Data Query
    CM:0x13
     LEN:0x00
Passenger flow data query is initiated by the host computer. Upon receiving command, HPC168 counter returns present accumulative passenger flow data.
e.g. Send passenger flow data query command to HPC168 counter with address 0x0001.
STX ID CM LEN DATA1 DATA2 CHK ETX
0x02 0x30 0x300x30 0x31 0x31 0x33 0x30 0x30 0x31 0x34 0x03
 
Response:
CM:0x93
     LEN:0x10
HPC168 Automatic Passenger Counter Camera for bus returns present accumulative passenger flow data.
DATA1: Divided into in, out, 8 bytes, unsigned integer.
DATA2: No effect, padded with 0.
among which: corresponding passenger flow sensor for in and out are accumulative number of guests coming in and number of guests coming out (hexadecimal).
e.g. ID=0001 HPC168 counter has number of guests coming in of 34 and number of guests coming out of 35, then returns:
STX ID CM LEN DATA DATE CHK ETX

Introduction


HPC168 automated passenger counter camera for bus provides rich data interface:

1. RJ45 network interface
Via RJ45 interface and HPC168 counter connection, client tool program views or sets working status and operates parameters. At the same time, HPC168 counter submits passenger flow data to the designated server in real time through RJ45 network interface.
2. Composite video output interface
Can be connected with vehicle-mounted display to visually display passenger counting results. Can also be connected with vehicle-mounted video recorder to save the passengers dynamic video of getting-on and getting-off in real time.
3. RS485 interface or RS232 interface
Provides one-way RS485 or RS232 for third-party equipment to conduct data calls, customizes baud rate and communication ID code.
4. Vehicle door switch signal
Can receive 8-36V voltage range vehicle door switch signal input. HPC168 counter stops counting once vehicle door is closed, and automatically starts counting when vehicle door is opened.
