Abstract
A low-cost scissors gate control system was achieved in this paper, which has many front controllers based on real-time operating system of free FreeRTOS, open-source uIP, and ARM Cortex-M3 MCU. This system realized a ID interface by using rfid technology or two-dimensional codes. Also TCP/IP data channel, gate control, information management and so on were carried out in this system. Moreover this paper described the implementation of the system. According to the actual situations, it indicated that this system runned reliably and stably.
