The invention discloses a Zigbee-based rail car anti-collision off-network proximity alarm system and method. The system comprises a main assembly and at least one auxiliary assembly, wherein each ofthe main assembly and the auxiliary assembly comprises a controller, an inductor and an alarm, the inductor comprises a Zigbee ad hoc network module, the transmission of a wireless signal is completedbetween the main assembly and the auxiliary assembly through the Zigbee ad hoc network module, and the auxiliary assembly only receives the wireless signal sent by the main assembly; the controller sends a control command to the inductor, and the inductor sends an omnidirectional wireless signal to the outside through the Zigbee ad hoc network module, monitors whether the wireless signal is received or not and controls the alarm to work or not. Within the effective working radius range, the system does not depend on transmission networks in any form, can sense each other, judge the distance between a target and the system itself by means of real-time detection of a receiver and a transmitter, and compare the distance with a set threshold value, therefore, judges whether to give an alarm or not, and plays a role in anti-collision early warning.

    本发明公开了一种基于Zigbee的轨道车防撞离网接近报警系统和方法,系统包括主组件和至少一个副组件,主组件和副组件均包括控制器、感应器和报警器,感应器包括Zigbee自组网模块,主组件与所述副组件之间通过Zigbee自组网模块完成无线信号的传输,副组件仅接收所述主组件发送的无线信号;控制器发送控制命令到感应器,感应器通过Zigbee自组网模块向外发送全向无线信号,同时监测是否收到无线信号并控制报警器是否工作;本发明能够在其有效工作半径范围内,不依赖任何形式的传输网络,可以相互感知,依靠接收、发射器的实时检测,判断目标和自己的距离,并以此值与设定阈值做比较,从而判断是否发出报警,起到防撞预警的作用。
