The invention relates to the technical field of vehicle burglary prevention, and particularly discloses a trailer access state detection system, a traction trailer and a method. The trailer access state detection system comprises a controller, an access detection module and a trailer load, the first end of the access detection module is connected with the trailer load, and the second end of the access detection module is connected with the input end of the controller; the access detection module is used for transmitting the detection signal subjected to current limiting processing to the trailer load, collecting a feedback signal of the trailer load at the same time, and transmitting the feedback signal to the controller; and the controller is used for judging whether the trailer load is in an online state or not according to the amplitude of the feedback signal. Through a mode of limiting excessive detection current from entering the LED lamp of the trailer load, the abnormal lightening condition in the trailer steering process is avoided, and the load detection range is relatively wide.

    本发明涉及车辆防盗技术领域,具体公开了一种挂车接入状态检测系统、牵引挂车及方法。该挂车接入状态检测系统包括:控制器、接入检测模块和挂车负载;所述接入检测模块的第一端与所述挂车负载连接,所述接入检测模块的第二端与所述控制器的输入端连接;所述接入检测模块,用于将限流处理后的检测信号传输至所述挂车负载,同时采集所述挂车负载的反馈信号,并将所述反馈信号传输至所述控制器;所述控制器,用于根据所述反馈信号的幅值,判断所述挂车负载是否处于在线状态。通过限制过大的检测电流进入到挂车负载的LED灯的方式,避免挂车转向过程中的异常点亮状况,且具备较宽的负载检测范围。
