负责民用网络摄像机与智能家居设备的嵌入式软件开发工作

Use C / C ++ language to develop and maintain the network camera software to assist the hardware staff to debug / locate the software system. It is responsible for solving the problems found by the testers in the system testing and acceptance test, and writing related work.Mainly responsible project:The United States VICON high-definition network camera dome embedded linux application software development: mainly responsible for the camera PTZ management module, alarm management module, network management module design and development work; in the PTZ control system, the optimal level of energy to improve the step In the alarm management module, the signal and condition variable are used to realize the alarm information in the multi-thread environment. In the alarm management module, the signal and the condition variable are used to realize the alarm information in the multi-thread environment. In the alarm management module, The notification mechanism, and in the special alarm event linkage device recording storage action.According to the ProfbelG video control protocol under ONVIF, the video control protocol library code of the network camera is designed, and the video control function of the third party platform conforming to the ONVIF protocol is realized.ONVIF standard protocol to achieve IPC network camera PTZ control function, mainly to achieve the PTZ PTZ continuous movement, relative movement, absolute movement control.

As the application software engineer of linux system, the design of AM335x (Cortex-A8 architecture) embedded linux platform and the communication server control software based on TCP / IP standard are designed in the electric vehicle high power wireless charging system.The main functions of the software are: to achieve high-power wireless charging control system in the WLAN wireless communication environment charge and stop control and protection, the relevant terminal equipment authentication and authentication, and the completion of electric vehicle charging operation decision control and management.The software consists of three parts: the charge management server WCCMS, the charging pile communication service unit CSU, and the vehicle communication service unit IVU. The charging management server WCCMS is mainly responsible for the multi-vehicle access, equipment authentication and charging decision control. The charging pile communication service unit CSU is responsible for the information exchange function of the charging pile to the WCCMS and the IVU unit. The vehicle communication service unit IVU is responsible for the vehicle terminal Reception of the interactive command, and reporting to the WCCMS the real-time status of the vehicle power receiving unit and the onboard battery management unit. Software uses multi-threaded architecture, thread and process between the use of TCP / UDP and message queue for information transmission.At the same time, the terminal authentication authentication function is studied, and a variety of encryption algorithms are understood to understand the principle of digital certificate.Prepared a communication protocol document between the systems, and a charging process specification document.
