And once the signal intensity of the current detection information is consistent with the intensity corresponding to the identification position, recording the identification position as a starting point.
Step 403: and outputting the identification information at the next identification position along the signal transmission direction by taking the starting point as a base point.
After confirming the starting point position, the next identification position along the signal transmission direction with the starting point as the base point is used for outputting identification information, each position is provided with a signal transceiver, and the signal transceivers are arranged in a segmented mode, so that the overall detection stability is improved.

Step 405: and confirming the damaged section in the leaky cable according to the starting point and the ending point.
And connecting the starting point with the end point according to the positions of the starting point and the end point, so as to confirm the damaged section in the leaky cable.
Referring to fig. 5, once the identification position of the transmission identification information is not consistent with the identification information of the next identification position, indicating that the end point position is not here, the position of the end point needs to be re-judged, the judging method includes the following steps:
step 500: the next identification position is taken as a middle point and identification information is transmitted in the signal transmission direction.

Step 501: and judging whether the identification information transmitted by the intermediate point is consistent with the identification information received by the next identification position.
And judging whether the identification information transmitted by the middle point is consistent with the identification information received by the next identification position or not, thereby judging whether the middle leaky cable is damaged or not.
Step 502: if the two are consistent, the intermediate point is taken as an end point.
Once the identification information transmitted by the intermediate point coincides with the identification information received by the next identification location, the intermediate point is taken as an end point, and there is no case where the leaky cable is broken.
Step 503: if not, the receiving point is used as an intermediate point to repeatedly send the identification information until the identification information transmitted by the intermediate point is consistent with the identification information received by the next identification position, and the intermediate point is used as an end point.
When the identification information transmitted by the intermediate point is inconsistent with the identification information received by the next identification position, the condition that the leaky cable is broken occurs at the intermediate point, so that the receiving point is used as the intermediate point to repeatedly send the identification information until the identification information transmitted by the intermediate point is consistent with the identification information received by the next identification position, the condition that the leaky cable is not broken in the section is indicated, and the intermediate point is used as an end point.
Referring to fig. 6, once a damaged section in a leaky cable has multiple sections instead of a single section, the method for detecting multiple sections includes the following steps:
step 600: the identification information is transmitted to the signal receiving direction according to the destination.
When the end position is known, the identification information is transmitted from the end position to the signal receiving direction for identification.
Step 601: if the signal receiving point receives the identification information, the damaged end is only one section.
The leaky cable transmits information from the signal transmitting point to the signal receiving point. Once the identification information is received by the signal receiving point, it indicates that no damage has occurred from the end point to the position where the receiving point is located, i.e. only one segment of the damaged end. Since the positions from the transmitting point to the starting point are already identified, only the positions from the signal receiving point to the end point need to be identified.
Step 602: if the signal receiving point does not receive the identification information, the signal receiving point has multi-segment damage, and transmits the identification information to the receiving end by taking the terminal point as the transmitting point, and repeatedly detects according to the identification method of the single-segment damaged segment until another damaged segment is obtained.
Once the signal receiving point does not receive the identification information, or the received identification information has wrong signal strength,
step 603: and transmitting the identification information to the signal receiving direction according to the end point in the other damaged section until the signal receiving point receives the identification information to obtain the multi-section damaged section.
And after the terminal point of the other section is obtained, the terminal point of the section is taken as a transmitting point, the identification information is transmitted to the signal receiving direction by the identification information until the signal receiving point receives the identification information, at the moment, a section of damaged leaky cable is obtained, and the steps are repeated to obtain a plurality of sections of damaged sections.
Referring to fig. 7, the identification information is received after being transmitted, and the identification accuracy of the identification information is judged, so that the condition of the identification information is known, and the verification method of the identification information includes the steps of:
step 700: and searching out the current number from a preset encryption database according to the current signal transmitting position and loading the current number into the identification information.
The encryption database is a preset database, and a unique number is matched through inputting the current transmitting position, so that the current number is searched from the encryption database through the current signal transmitting position, and the number is loaded into the identification information to play a role in synchronous transmission.
Step 701: the current number is decoded from the identification information received from the current receiving position, and the current number is substituted into a receiving function preset in the current receiving position to calculate a feedback value.
The identification information with the number is received by the receiving position after being sent, the current number is decoded from the identification information received by the current receiving position, and the current number is substituted into the receiving function of the current receiving position to calculate the feedback value.
The receiving function is a preset function, and the feedback value is obtained by substituting the serial number, and the receiving function is a function preset by the staff, and different feedback values can be obtained by substituting different functions, and the receiving function is selected by the staff according to the actual situation, which is not described herein.
Step 702: and sending the feedback value to the transmitting position, and substituting the feedback value into the transmitting position to calculate a check value from a preset transmitting function.
And after the feedback value is calculated, the feedback value is sent to the transmitting position, and the received feedback value is substituted into a transmitting function preset in the transmitting position to calculate a check value. The transmission function is a function preset by a worker, and different check values can be obtained by substituting different functions, and the worker selects the function according to actual conditions, which is not described herein.
Step 703: if the check value is consistent with the serial number, the check is finished; otherwise, prompt is carried out.
After receiving the check value, once the check value is consistent with the serial number, the check is completed at this time.
After receiving the check value, once the check value is inconsistent with the serial number, the identification information at the moment is indicated to have a problem, and the verification is not completed, and then prompt is carried out.
