Example two
Fig. 3 is a flowchart of a cable outgoing end detection method according to a second embodiment of the present invention, where the cable outgoing end detection method is applied to the cable outgoing end detection system provided in this embodiment, the cable outgoing end detection method may be executed by a cable outgoing end detection device, the cable outgoing end detection device may be implemented in a hardware and/or software manner, and the cable outgoing end detection device may be configured in electronic equipment in each engineering project scenario. As shown in fig. 3, the method for detecting the cable outlet end includes:
s310, before the cable to be detected is detected, the switching relay in the signal emitter is controlled to be in a disconnected state, and when the disconnection distinguishing module judges that the cable to be detected is out of power, the switching relay is controlled to be in a connected state.
It can be understood that, before the cable outlet end is detected, the measuring end of the signal emitter is electrically connected with the outlet initial end of the cable to be detected, the cable detecting end of the signal detector is electrically connected with the outlet end of the cable to be detected, the first common end of the signal emitter and the second common end of the signal detector can be grounded, or can be connected through a special line to form a loop, so that the outlet detection loop of the cable to be detected is formed by the signal emitter, the cable to be detected and the signal detector.
Specifically, before the cable to be detected is detected, the switch relay in the signal transmitter is controlled to be in a disconnected state, the disconnection module starts to sample the voltage value of the cable to be detected and judges the voltage value, if the cable to be detected is judged to be electrified, the switch relay is controlled to be in the disconnected state, the measuring channel of the cable to be detected is automatically disconnected, an alarm signal is output, and accidents are prevented. And if the cable to be measured is judged to be free of electricity, the switch relay is controlled to be in a conducting state, and the strip measuring channel of the cable to be measured is in a measurable state.
And S320, when the measuring relay in the switch relay and the signal detector is in a conducting state, controlling the measuring current input module in the signal detector to input a loop current value to the outgoing line detection loop, and measuring a loop voltage value of the outgoing line detection loop through the voltage detection module in the signal detector.

Specifically, a constant current with adjustable magnitude, namely a loop current value, is input into a measurement current input module in the signal detector, and a voltage value of the outgoing line detection loop is measured through a voltage detection module in the signal detector, so that a loop resistance value of the outgoing line detection loop is calculated.
Because the measured resistance value of each measuring channel is different, if the loop resistance value calculated by the signal detector is equal to the measured resistance value of a certain measuring channel, the cable outgoing line starting end connected with the cable detection end and the signal emitter is judged to be the starting end and the tail end of the same cable, namely the cable outgoing line starting end and the cable outgoing line tail end to be measured are determined to be the same cable; and if the difference between the calculated loop resistance value and the measured resistance of each measuring channel is extremely large, judging that the cable to be measured at the cable detection end fails, and determining that the cable to be measured fails.
On the basis, the detection result of whether the outgoing line starting end and the outgoing line tail end of the cable to be detected are the same cable or not and the cable to be detected are correspondingly displayed on the display screen.
According to the technical scheme of the embodiment of the invention, the switch relay in the signal emitter is controlled to be in the off state before the cable to be detected is detected, and the switch relay is controlled to be in the on state when the disconnection module judges that the cable to be detected is out of power; when the measuring relay in the switch relay and the signal detector is in a conducting state, controlling a measuring current input module in the signal detector to input a loop current value to an outgoing line detection loop, and measuring a loop voltage value of the outgoing line detection loop through a voltage detection module in the signal detector; and determining whether the outgoing line starting end of the cable to be tested and the outgoing line tail end of the cable to be tested are the same cable or not according to the loop resistance value and the measurement resistance value of the measurement resistor in the signal transmitter.
