| 1. The research purpose and significance of this topic : With the popularity of the Internet in our country, WeChat has become an indispensable communication tool in people's daily lives. According to relevant data, the average daily active users of WeChat in the first half of 2018 exceeded 1 billion. Such a huge number of users has given rise to the rapid development of WeChat mini programs. In daily life, many industries provide WeChat mini programs to make users more convenient to use. The same home appliance repair system applet can also bring convenience to users. Traditional home appliance repair requires users to go out temporarily to find a repairman, which is very inconvenient for users who are in a hurry. And he didn't know whether the maintenance master was currently available and could come to the house for repairs. But the home appliance repair system applet is different. First of all, it does not require users to download an app and does not occupy the space and memory of the mobile phone. Secondly, you can place an order directly on the mini program and find a nearby repairman who is available to come to your home for repairs. It allows users to find maintenance technicians without leaving home. At the same time, it can make appointments for maintenance technicians to come to their homes in advance, allowing maintenance technicians to come to their homes for repairs when users are free. This small program allows users to save time and provide convenience in daily life. Users who do not usually leave home can also quickly find a repairman to come to their home, which can help many people in need. 【588】SSM-based home appliance repair system WeChat applet source code and thesis proposal report task book |
In recent years, WeChat mini programs have developed rapidly due to the large number of WeChat users. Since the WeChat mini program was launched, many companies have been ready to take action. Because the rise of WeChat mini programs has given hope to many companies that cannot afford traditional APP development costs. For college students to start their own businesses, the cost of mini programs is also very cheap compared to APP development. As the main product promoted by WeChat, mini programs have never faded away from the public eye. Every move they make affects the hearts of Internet practitioners. The rise of the mobile Internet brought a wave of entrepreneurial enthusiasm. Compared with APPs, the development cost of small programs is very low, which brings opportunities to independent developers. Relying on WeChat's national-level chat tool, the flexibility of WeChat applet allows it to aggregate various services based on scenarios. The usage rate of apps on mobile phones does not exceed 40%. The characteristics of mini programs that "no need to download, can be used immediately, and run away after use" allow it to become a supplementary application to the head app and replace some low-frequency service apps. In fact, the most commonly used types of mini programs are life services and tools. Most of them are applications based on life scenarios. For general life needs, they can already meet the needs of most users. WeChat attaches as much importance to mini programs as it did to official accounts back then. Although it does not actively promote it, the speed of opening functions is like squeezing out toothpaste. However, according to network statistics, WeChat has officially released 41 mini program scene entrances. Souyisou, QR code, official account, LBS, mini program system entrance, etc. are the main entrance scenes for mini program traffic guidance. Functions such as linking public accounts to mini programs and inserting mini programs into articles are open, making the entrance scenarios of mini programs very rich. However, after some screening, only about 32 of them can actually be applied in life. The application of WeChat mini programs in various industries has greatly saved the use space of mobile phones, making customers more sticky and more dependent on WeChat. Nowadays, people's usage habits tend to be mobile, and they are heavily dependent on WeChat mini programs that have rigid needs. For some low-frequency applications, users are also looking forward to a more convenient way to replace APP. Nowadays, mini programs have achieved rapid development in various industries and have had a profound impact. As tools, mini programs developed for the purpose of low-frequency practicality are becoming more and more popular among consumers today. Taking the low-frequency tourism industry as an example, developing WeChat mini programs can not only expand the customer acquisition radius, but also extend tourism-related knowledge, improve user travel experience, and even directly use WeChat mini programs to monetize user traffic. Every node of the mobile Internet will give birth to a new business model. For small programs, the time for its growth is too short, and most people cannot see the future of small program entrepreneurship. Only pioneers can reap huge development dividends. The current layout of small programs is to seize the market. Next, what are the advantages of developing our home appliance repair app? Home appliances are used frequently, and problems will inevitably occur sometimes. When a malfunction occurs, a repairman needs to be found quickly to ensure the normal operation of daily life. In the past, when consumers had repair needs, they usually looked for some offline "psoriasis" advertisements or went to physical stores to find repairmen. However, these methods were extremely inefficient in terms of communication and time. And this method is not suitable for those who don’t like to go out. In daily life, it is inevitable that they don’t want to move around after returning home from work. There are also some people who have just moved and do not know the geography of the area. In this case, it is very inconvenient for them to find a repairman to come to repair their home appliances. To sum up, it is necessary to develop a home appliance repair app. Users can place an order and make an appointment for repair on their mobile phone without going out. The repairman can receive the order notification in real time and leave immediately after use. It does not occupy memory and is in line with the requirements of home appliance repair. Low frequency usage scenarios. What are the advantages of developing home appliance repair app? 1. Safe service, cost-effective Compared with small advertisements on the roadside, the maintenance platform guarantees the credibility of both supply and demand parties, with transparent prices and traceable services. The maintenance services provided by small program providers not only have strict regulations on maintenance efficiency, but also undergo strict screening in the selection of maintenance talents. There is also a word-of-mouth evaluation mechanism to protect the rights and interests of both parties. 2. Data integration to improve service levels In the home appliance repair app, when users place an order, they can evaluate the order and rate the repairman after completing the order. You can know which maintenance technicians have higher service levels. 3. Make a reservation in advance, no need to wait In the Home Appliance Repair app, users can place an order in advance and make an appointment for a technician to come and perform repairs when they are free. This can help users repair more quickly, conveniently and effectively. 4. Convenient and fast, no need to occupy memory space Compared with traditional apps, mini programs "do not need to be downloaded, can be used immediately, and can be used immediately after use" for users, achieving true convenience and efficiency. 【588】SSM-based home appliance repair system WeChat applet source code and thesis proposal report task book |
