Zhengzhou University of light industry -- development and sharing of harmonyos pet health system

In this issue, we bring you the sharing of Yang Guang, developer of family pet health monitoring system , I hope I can give you HarmonyOS The development journey brings inspiration ~

Introduce

Yang Guang , Student of Zhengzhou University of light industry , yes HarmonyOS The main developer of family pet health monitoring system . Yang Guang's team consists of Yang Guang 、 Yuan Keyun 、 Zhang Xiaolan 、 Li Weishan 、 Du Xuening et al , They are respectively responsible for the technical development of the whole project 、 hardware system 、 Data collection and market research .

01  Why develop this system ？

• background

With the improvement of people's living standards , The number of pets raised in urban and rural areas in China is increasing year by year , But the immunization rate is very low , And pet feeding management is not strict , Cause stray cats 、 The number of dogs has increased greatly , Increases the risk of rabies transmission .

therefore , Yang Guang and his team decided to develop a pet health monitoring system . The system consists of hardware and software , The details are shown in the table below ：

The pet collar detects the pet's body data through the sensor and uploads it to the cloud , Then through convolution neural network , Analyze the data , Finally, send the analysis results to the pet big data monitoring and management platform developed by the team .

02 HarmonyOS Learning and project development

• When recalling and replying to the whole project , Yang Guang has a lot of feelings

“ The early stage of the project is mainly the learning of knowledge and technology . I was in 21 year 3 Who entered this project in January , In order to support the development of the project , After entering the project, I began to learn internet development technology ,21 year 7 Learning begins in June HarmonyOS technology , At that time, Yuan Liang, a graduate student in the studio, led us from HarmonyOS Of Ability Starting to learn , Then the interface is developed 、 Function development 、 Database front and back-end connection and other aspects of learning , Continue until 10 month .”

“ In the middle of the project, it is mainly to realize the function of collecting data from pet collars . Our initial idea was to use NodeMCU Connect the sensor and professional board , Later, I managed to encapsulate the sensor and board in a small collar , Finally decided to choose the bear pie Hi3861 Make it , This section is the longest .”“ The later stage of the project is mainly to optimize the design of pet collars . Our first generation of pet collars are actually relatively simple , There have been many problems in the process of use , We solve and optimize the problems one by one , Now the second generation of products .”“  The teacher also trained our team in algorithms , And recommend us to join Huawei's ‘AI Innovation practice competition ’ and ‘2021 Future cup HarmonyOS Technology application innovation competition ’, Adopt the way of replacing practice with war , Test our learning results .”

03  Future prospects and plans

• Future outlook

When it comes to the future outlook of the product , Yang Guang is also confident .“ At present, our pet collar has been iterated to the second generation , And have found some pet shops to communicate for experimental use , In the future, we will optimize it according to the usage , When the pet collar is mature and stable , We will promote it .” Of course, we also hope to expand the field of pet collars in the future , such as ： Cooperate with the team building the knowledge map of pet disease diagnosis , This will help improve the accuracy of our pet collar , When a pet gets sick , Owners can get alerts from the pet health warning system faster , Bring valuable treatment time to pets .”

• Future plans

When asked about their future project plans , Yang Guang said they might participate in HarmonyOS Developer innovation competition .

In order to participate in HarmonyOS Developer innovation competition , They prepared a project on infantile cerebral palsy . After their investigation, they found that the audience of this area is still very large , So they feel that the research and development of this project is valuable , At present, preliminary preparations are under way .

Conclusion

“ As a contemporary college student , We should look up to the stars , But also down-to-earth , And we believe that the youth of struggle is the most wonderful , I believe we can prove ourselves through our own practical actions .” This is a sentence written by Yang Guang in the team Introduction . I wish Yang Guang's team can achieve satisfactory results in the next new project , We also expect them to continue to create more products with practical significance and functions , Change your life with technology , Benefit society . Future period ！
