B-side hardware from 0 to 1 (piece): R & D stage

Part I we talked about the feasibility analysis of the B-side hardware products, by analysis of the feasibility of the product, the company team to understand market, customer needs, competition, key technology, financial condition and other relevant circumstances. Once the project has confirmed that the product, the product enters the second phase of the process: product development.
Demand B-side hardware products usually have two ways, from custom or based on the company's own research and development project. Due to different sources, although the general process research and development processes are similar, but there are some differences in the development process control (customized main difference is that each of the key aspects to inform the progress of the project to the customer. The progress of the project in accordance with contract requirements to report to the relevant stakeholders people.). This will be a chauffeur-driven behavior intelligent monitoring terminal as an example, chat with the B-side hardware product development process.
Overall R & D stage can be divided into several such large areas: system design, implementation of research and development, product testing, product certification. Different sizes, different requirements of the product, in this part of the process will be a few big cut.

System Design

By pre-feasibility analysis, business process monitoring terminal has been clearly need to be implemented. Drawn by the business process monitoring product on the lower end of the topology of FIG.
Core Business Process Description: acquiring video driver of the vehicle during driving operation by a camera, a video monitor combined algorithms analyze whether there is smoke drivers, call, fatigue driving, turn signal to change lanes and other irregularities by the terminal analysis of the driving behavior. When the driver detects the presence of irregularities when driving behavior, alert and non-standard terminal driving the process of shooting photos and videos uploaded to the monitoring platform, as a specification driver driving behavior assessment basis.
Analysis of core business process monitoring terminal, wherein the key technologies in combination, a full product will split into several sub-products so that:
A, a terminal body (hardware main body): video collection, video analysis, locally stored video, network communications, real-time location, driver behavior analysis, alarm processing, image display and other services.
B, mobile terminal APP: mobile terminal APP main body contains three key roles - product operation and maintenance staff, drivers, vehicles operating companies. APP will be split into two core version: operation and maintenance APP, monitoring APP. Operation and maintenance APP intended primarily for product operation and maintenance personnel.
APP is mainly used for operation and maintenance terminal hardware deployment, to provide a more convenient way for measurement products, improve the success rate and efficiency of product deployment. Terminals deployed on the car, it is necessary to adjust the camera parameters, calibration parameters detected, the communication quality inspection process. Operation and maintenance APP allows the company operation and maintenance personnel to quickly deploy the product, find a product problem.
Monitoring APP realize statement analysis, view alarm video, driver assessment score, turnout rates and other services. To meet the driver, the operating company oversight of the entire driving process, query, assessment.

lane departure warning and to maintain the use of machine vision sensors, the vehicle is always running in the lane line, to prevent the vehicle because the current driving lane departure resulting from traffic accidents, improve traffic safety. And to explain the image by image analysis of large-scale parallel processing system by analyzing the camera image information transfer, and analysis to inform the driver, realize driver assistance functions. More precisely, providing a warning indicator or by voice when the vehicle approaches the edge of the roadway or in danger, or voice indicator to alert the driver in time to avoid the danger.
2, the vehicle obstacle detection around
the vehicle around obstacles including vehicles, pedestrians and road around the facilities, such as through a camera or infrared sensor can sense the presence of these obstacles around the vehicle, and real-time tracking, you can also alert the driver to take in times of danger avoidance measures.
3, forward collision detection
to avoid car due to lack of safe distance between vehicles lead to evil ××× through the rear-end collision accident, detection and tracking front of the vehicle is also an important means of improving safety. Effective detection using real-time information from various sensors on the front of the vehicle and vehicle distance when the safety car was found from the lack of timely issue a warning to the driver's voice, prompting them to take the necessary measures to maintain a safe distance between vehicles to avoid rear-end collision accident occurred.
4, the pedestrian detection

Different industries have different products industry testing standards, hardware products referenced test specifications will be different. A same electrical specifications, will be different for different industries products. Such as: electrostatic discharge (ESD). In the field of power industry typically requires four most senior, the automotive sector is usually level 3, level 2 for the consumer sector. Hardware Product managers need accurate information on industry-related test requirements, industry standards.
If it comes from customized products, signed a contract at the beginning Party will provide a product testing documentation. The late acceptance and product testing, product testing will follow this part Instructions related testing and certification bodies to test and issue test reports. When the product to be delivered from the supplier Party will take samples for testing the product inspection to verify that products comply with contract requirements. There are some customers can not afford to signing of the contract or no effort to provide a more complete description of the product testing, then you need to test the company's R & D department, or provide a list of self-test, post-test acceptance of the product in accordance with the tests described in the list acceptance. Although this part of the work will bring additional workload, but to follow this procedure will facilitate product acceptance both sides to avoid wrangling product acceptance occurs.
The above is the key to the B-side hardware product development process consists of. Matters in these links hardware product manager takes a lot of energy to participate in the early definition of product demand, product solutions and post-production testing. Intermediate technology can process and project managers work together to monitor the situation to promote the product. A good B-side hardware product manager, to have a deep insight into the industry, understand the industry issues, there is a clear understanding of customer scenarios. Able to develop the technology R & D team with excellent technical program, the balance of the relationship between performance and cost, the industry standard, the testing process more familiar. Only in this way can accomplish a good B-side hardware products.
