The Software Design And Implementation Of House Danger Alarming System Which Based On WeChat

With the high speed development of mobile Internet in China, the concept of smart home has been got more and more people’s attention. Given the current WeChat in our country has a large user groups and its good open feature. Presenting the information which users want know in real time through WeChat platform. Not only can shorten the product development cycle, reduce cost, and also can more close to the actual needs of users, reduce the cost of studying and using.For a long time, people are very concerned about the family that may occur such as gas leakage or fire safety hidden trouble. Aiming at this requirement, this paper designed a set of complete family security alarming system, including:a variety of data acquisition sensors and Ethernet hardware and WeChat platform software platform of two parts. Hardware acquisition use STM32 MCU as the core, through the use of temperature and humidity sensor, smoke sensor to collect indoor temperature, humidity, smoke concentration, data were collected will be sent through the Ethernet module to the remote data receiving server. Software platform consists of the WeChat public platform and application service on SAE platform, WeChat public platform will transmit user commands to command response service page on SAE platform, and then service page send response information though public platform to the user. Application service on SAE platform including the communication protocol of WeChat public platform, hardware, data reception service, binding equipment, data query service and alarm service, this paper mainly studies the underlying data transmission of Ethernet and WeChat public platform construction.At first, this paper completed the diagram of the overall system design, and introduced detailed design scheme of the system. Secondly, give device type selection of the data acquisition modules which offers the data of sources. Once more, on RVKDK4 software development platform, use the STM32 microcontroller as the main control chip, combining Ethernet module, completed the Ethernet module drive and the transplantation of uIP protocol stack, and implements the Webclient method to send data to the hardware data reception service page. Next, write the communication protocol between WeChat public platform and developer server, complete the construction of the WeChat public platform. On this basis, realized the database design, as well as the device relative services, WeChat query data services, hardware, data reception service, such as abnormal alarming function. Finally, the design of this article has carried on the experimental verification, the results show that the hardware can stably send data through Ethernet to data reception service page,each function of the WeChat public platform runs normally.
