The WeChat 5.0 test version has a change that everyone is shocked - "Sweep" from the secondary menu directly to the first level menu, not only can scan to add friends, but also added scanning QR code, scanning Barcode, scanning street view, translation function. In other words, any offline scenes, such as shopping rates, such as discounts on scenic spots, can be completed using WeChat scanning.
Seeing WeChat want to strengthen the trend of people and things interconnection, Zheng Wenxiao, a student of North Post Research II, and two students have developed a system that can query and monitor a parking area on the North Post campus through the WeChat public account, and innovate on the WeChat public platform. The regional competition in the competition won the gold medal in the northern division.
Zheng Wenxiao said that considering that most of WeChat public accounts are dealing with software and databases, they are basically querying database applications, and they have to play open source hardware, so they want to be able to make a combination - use WeChat to control hardware.
Their WeChat public account "North Post Campus Parking Space" can realize the parking space inquiry, that is, send "c" to query the parking space information, WeChat will return the number of free parking spaces and real-time image information according to the situation monitored by their hardware devices. If the owner does not know how to get to the parking space, he can also send local location information to return the “North Post Campus Parking Space†to a route navigation information. After parking, you can mark the location of the vehicle and check the real-time status of the parking space.
The sensor device that returns the live information in real time is that they use a raspberry pie to carry a camera to periodically capture the image information of the four parking spaces on the scene. After image recognition, it is judged whether the parking space is occupied. After the sensor has obtained the number of free parking spaces, the network transmits this information back to the server of the WeChat public platform, and the data can be returned to the queried user.

At present, Zheng Wenxiao and team members are still improving the technology of the system. For example, the poor light at night will affect the image recognition. They consider using infrared technology to solve this problem. Subsequent they intend to extend the functionality of the system before and after parking, such as parking reservations, video surveillance, and vehicle change alarms. In terms of video function, this allows the owner of the marked parking space to see the condition of the car, such as knowing if the car has been driven away, who is driving away, and enhancing safety.
They feel that the vehicle exchange model can be made in the future. For example, the parking spaces in the general community are sold to a certain owner, but if the owner has a business trip or long-term absence, they can rent it to the temporary need and do it through WeChat. A platform for information exchange. However, he also said that the current team is still thinking about the technical aspects. The scope of the inquiry is limited to four parking spaces in a parking area in Beiyou. It is also in the initial stage, and the business is less focused.
