Vibration signal cable rapid detection device and detection method

The invention provides a vibration signal cable rapid detection device and method, and the method employs a loop circuit detection principle to add a voltage to two ends of a wire, and the middle of the wire is connected with an LED in series. After the detected cable is connected into the device, the cable path is connected with the circuit loop, and the LED lamp is turned on; if the cable is disconnected, the circuit loop is blocked, and the LED lamp is not turned on; whether the detected cable is normal or not is judged according to the condition of the LED, and the function of rapidly detecting the vibration signal cable is achieved. Two AAA batteries are used for supplying power, power-on detection is carried out through an internal circuit, an LED lamp is used as a display mode, the cost is low, and large-scale popularization is facilitated. According to the invention, the two 10-32UNF or BNC terminals are adopted to directly and quickly connect the cable to be detected to the detection device for cable
