Quality Control

The quality control of ORVIKA GPS positioning, on-board video and fuel consumption monitoring equipment can be divided into the following 12 core processes:

Raw material inspection → SMT production → semi-finished product inspection → program burning → complete machine assembly → function test → precision calibration → platform joint debugging → aging test → environmental reliability test → finished product inspection → packaging and delivery

1. Control of suppliers and raw materials

To screen, evaluate and regularly audit the core suppliers, mainly checking:

* GPS/Beidou positioning module

* 4G communication module and SIM card interface

* Camera, lens and infrared lamp

* Fuel sensor and acquisition module

* PCB, power chip and memory

* Battery, harness, connector and housing

* SD card, antenna and accessories

Incoming materials shall be inspected for model, quantity, appearance, size, electrical performance and batch consistency. Unqualified materials shall not be put into production.

2. SMT mounting and soldering inspection

After the PCB is pasted and soldered, proceed to:

* Solder paste thickness inspection

* AOI Automatic Optical Inspection

* Check the position and direction of components

* Inspection for poor welding, continuous welding and missing welding

* Manual re-inspection of key welding points

* PCB power-on and short-circuit detection

Ensure the reliability of circuit board welding and reduce the probability of disconnection, crash and abnormal function during the operation of equipment.

3. Semi-finished product function test

Before equipment assembly, perform basic function test on the main board:

* Power input and operating current

* 4G Internet connection

* GPS/Beidou positioning

* SIM card and storage function

* ACC, relay and I/O interface

* RS232, RS485, CAN and other interfaces

* Camera and audio interface

* Oil quantity data acquisition interface

4. Program burning and version management

Burn the corresponding firmware for each device and establish a unified version management mechanism:

* Firmware version check

* Write IMEI and equipment number

* Communication protocol configuration

* Server IP and port settings

* APN and network parameter settings

* OTA remote upgrade test

* Prevent wrong burning, missing burning and version mixing

5.Complete machine assembly management and control

Complete the equipment assembly according to the standard operation instructions, and focus on the following inspections:

* Fixing of main board, antenna and module

* Installation of camera and lens

* Harness connection and port locking

* Screw torque and structural soundness

* Heat conduction, dust prevention and insulation treatment

* Seal ring, gluing and waterproof treatment

* Case clearance and product appearance

6.GPS positioning function test

Main tests of GPS positioning equipment:

* Number of GPS/Beidou search satellites

* Cold start and hot start positioning time

* Static and dynamic positioning accuracy

* Vehicle real-time position upload

* Historical track playback

* ACC ignition and flameout status

* Electronic fence and overspeed alarm

* Alarm for power failure, vibration, removal, etc.

* Positioning performance in weak signal environment

* Data supplementary transmission after the equipment is offline

7.On-board video function test

Main tests of video equipment:

* Camera image clarity

* Day, night and infrared effect

* Video live preview

* Video storage and loop overlay

* Multiple cameras work synchronously

: Remote video retrieval and playback

* SD card anomaly detection

* Power-off video protection

* Audio capture and intercom function

* 4G network video transmission stability

* ADAS/DMS function and alarm accuracy

8. Fuel consumption equipment calibration and testing

Main tests of fuel consumption all-in-one machine and fuel quantity sensor:

* Sensor zero calibration

* Full scale calibration

* Oil level data acquisition accuracy

* Level change linearity test

* Fuel curve stability

* Identification of refueling, oil leakage and abnormal oil drop

* Filtering of oil quantity fluctuation during driving

* RS485, analog or digital signal output

* Stability of communication between sensor and host

* Fuel tank volume calibration and platform data matching

* Measurement deviation in high and low temperature environment

9.Joint commissioning of equipment and platform

The whole set of equipment shall be jointly debugged with the management platform to verify:

* Equipment on-line and identification

: Real-time positioning and trajectory upload

* Video preview, playback and download

* Display of fuel quantity data and curves

* Refueling, oil stealing, oil leakage alarm

* Equipment offline and abnormal alarm

* Instruction issuing and parameter modification

* Multi-language and network adaptation in different countries

* Data synchronization between mobile phone and computer

10.Aging test

The finished product shall be electrified continuously for a certain period of time to simulate the long-term working state. Check:

* Whether the device freezes, reboots, or is disconnected

* Positioning and network stability

* Whether the video recording is continuous

* Whether the fuel quantity data jumps abnormally

* Whether the temperature rise of equipment is normal

* Whether the storage and data upload are complete

Conduct quarantine, analysis, maintenance and retest after finding abnormal products.

11. Environmental and Reliability Testing

According to product specifications and customer requirements, we can carry out:

* High temperature, low temperature and temperature cycle test

* Vibration and drop test

* Waterproof and dustproof test

* Electrostatic Immunity Test

* Power Surge and Impulse Test

* Reverse connection, overvoltage and short circuit protection test

* Voltage fluctuation test at the moment of vehicle starting

* Long time network weak signal test

12. Finished product inspection and delivery management

Final inspection before product shipment:

* Appearance, label and model inspection

* Check of IMEI, serial number and platform information

* Sampling inspection or full inspection of main functions

* Inspection of accessories, harnesses and instructions

* Check of packing protection and packing quantity

* Retain test records and product batch information

Each product establishes a unique serial number to realize the traceability of the whole process from raw materials, production, testing to after-sales service.
