[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] The embodiment of the present invention provides an underwater sensor insulation detection method, which determines the insulation condition of the underwater sensor by sending a detection pulse voltage to the spare core wire in the multi-core watertight cable and monitoring the insulation value transmitted back by the spare core wire. Continuous detection can be achieved without interrupting the sensor signal acquisition.

[0030] According to an embodiment of the present invention, an embodiment of an underwater sensor insulation detection method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] In this embodiment, a method for detecting insulation of an underwater sensor is provided, and the method is applied to an insulation detector in an underwater data cabin; the underwater data cabin is connected to the underwater sensor through a multi-core watertight cable; the multi-core watertight cable includes a signal line and a first spare core wire and a second spare core wire; in the underwater data cabin, both ends of the first spare core wire are connected to the inside of the underwater sensor and the insulation detector, and both ends of the second spare core wire are connected to the outside of the underwater sensor and the insulation detector. Figure 1 : is a flow chart of an underwater sensor insulation detection method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0032] Step S101, sending a detection pulse voltage to the first spare core wire and the second spare core wire, and detecting a first insulation value on the first spare core wire and a second insulation value on the second spare core wire respectively.

[0033] There is no electrical connection between the spare core wire and the signal wire in the multi-core watertight cable, and they are insulated from each other. However, in the same environment, when any of the underwater sensors and multi-core watertight cables is invaded by seawater, it will invade the signal wire and spare core wire. Therefore, by detecting the insulation value on the spare core wire, it is possible to determine whether there are insulation problems in underwater sensors, multi-core watertight cables and other equipment, and then determine whether there is seawater intrusion in the underwater equipment, so that the staff can deal with it in time.

[0034] By detecting the first insulation value and the second insulation value on the first spare core wire and the second spare core wire, it is possible not only to determine whether there is an insulation problem with equipment such as underwater sensors, but also to further locate the insulation problem of the underwater sensor with the insulation problem based on the connection status of the first spare core wire and the second spare core wire, and determine which part has seawater intrusion.

[0035] When the waterproof shell of the underwater sensor is damaged and seawater invades, the interior of the underwater sensor will be filled with seawater, the first spare core wire will come into contact with the seawater, and the test pulse voltage will return to the insulation tester through the first spare core wire. The insulation tester detects that the first insulation value is reduced.

[0036] When the waterproof casing of the watertight cable is damaged, causing seawater to invade, the second spare core wire will come into contact with the seawater, and the test pulse voltage will return to the insulation tester through the second spare core wire. The insulation tester will detect a decrease in the second insulation value.

[0037] The insulation tester in the underwater data cabin sends a detection pulse voltage to the spare core wire and detects the insulation value on the spare core wire. The insulation tester can be used in conjunction with the remote monitoring system to enable staff to monitor the status of underwater equipment from a distance.

[0038] The magnitude of the detection pulse voltage shall not exceed the maximum operating voltage of the underwater sensor. The detection pulse voltage can be directly input by the staff or determined according to the insulation level of the underwater sensor. There is no restriction on how to obtain the insulation value. The insulation value can be obtained by measuring the leakage current at both ends of the sensor and calculating the ratio of the detection voltage to the leakage current. The leakage current can be measured by a special instrument such as a leakage current tester.

[0039] Step S102: Generate an insulation detection result according to the first insulation value and the second insulation value.

[0040] The insulation test result can be obtained by comparing the insulation values ​​on the first spare core wire and the second spare core wire with the expected insulation value. If the insulation value on the first spare core wire is lower than the expected insulation value, it indicates that there is an insulation risk inside the underwater sensor, and the shell of the underwater sensor may be broken. Isolation measures need to be taken to reduce the fault caused by abnormal insulation. If the insulation value on the second spare core wire is lower than the expected insulation value, it indicates that there is an insulation risk outside the underwater sensor, and the shell of the multi-core watertight cable may be broken. Isolation measures need to be taken to reduce the fault caused by abnormal insulation. Among them, the isolation measures can be disconnecting the underwater sensor circuit, etc.

[0041] The expected insulation value can be determined based on the technical specifications of the underwater sensor. When comparing the insulation value of the spare core wire with the expected insulation value, an error interval can be set. If the absolute value of the difference between the insulation value on the spare core wire and the expected insulation value is within the error interval, it can also be determined that the insulation of the underwater sensor is normal.

[0042] After obtaining the insulation test results, the test pulse voltage, the insulation value on the spare core wire and the insulation test results can be uploaded to the system and stored in the database. The data in the database can also be analyzed later.

[0043] In the underwater sensor insulation detection method provided in this embodiment, the signal line, the first spare core line and the second spare core line in the multi-core watertight cable are isolated from each other, and a detection pulse voltage is sent to the first spare core line and the second spare core line, which has little impact on the signal in the signal line, and can perform real-time insulation detection on the underwater sensor. The two ends of the first spare core line are connected to the inside of the underwater sensor and the insulation detector, and the two ends of the second spare core line are connected to the outside of the underwater sensor and the insulation detector. By respectively collecting the first insulation value on the first spare core line and the second insulation value on the second spare core line, it can be determined whether there is an insulation problem in the underwater sensor, and the insulation problem can be located.

[0044] In this embodiment, a method for detecting insulation of an underwater sensor is provided, and the method is applied to an insulation detector in an underwater data cabin; the underwater data cabin is connected to the underwater sensor through a multi-core watertight cable; the multi-core watertight cable includes a signal line and a first spare core wire and a second spare core wire; in the underwater data cabin, both ends of the first spare core wire are connected to the inside of the underwater sensor and the insulation detector, and both ends of the second spare core wire are connected to the outside of the underwater sensor and the insulation detector. Figure 2 : is a flow chart of an underwater sensor insulation detection method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0045] Step S201, sending a detection pulse voltage to the first spare core wire and the second spare core wire, and detecting a first insulation value on the first spare core wire and a second insulation value on the second spare core wire respectively.

[0046] For details, please see Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0047] Step S202: Generate an insulation detection result according to the first insulation value and the second insulation value.

[0048] Specifically, the above step S202 includes:

[0049] Step S2021, obtaining an expected insulation value, wherein the expected insulation value matches the detection pulse voltage.

[0050] The expected insulation value can be obtained in any manner and can be obtained from the technical manual of the underwater sensor. The expected insulation value can also be determined by actually measuring the insulation value of the underwater sensor under normal working conditions. The measurement can be performed using equipment such as an insulation resistance tester.

[0051] Step S2022: compare the first insulation value with the expected insulation value, and generate a sensor internal insulation detection result based on the comparison result.

[0052] Among them, if the first insulation value is less than the expected insulation value, there is an insulation abnormality inside the sensor.

[0053] An error range can be set to determine whether the ratio of the first insulation value to the expected insulation value is within the error range. If it is within the error range, the internal insulation of the sensor is normal. If it is not within the error range and the ratio is less than 1, the internal insulation of the sensor is abnormal and corresponding measures need to be taken.

[0054] After detecting the internal insulation abnormality of the sensor, the first signal transmitted by the signal line can be collected to determine whether there is an obvious error in the first signal, and the internal insulation detection result of the sensor can be verified twice. If there is an obvious error in the first signal, it is judged that the internal insulation detection result of the sensor is correct, and an insulation abnormality has occurred inside the underwater sensor. If there is no obvious error in the first signal, the detection pulse voltage is sent to the first spare core wire again, the first insulation value on the first spare core wire is obtained, and the first insulation value is compared with the expected insulation value to generate a secondary sensor internal insulation detection result. If the secondary sensor internal insulation detection result still does not show insulation abnormality, it is determined that there is insulation abnormality inside the underwater sensor.

[0055] Step S2023, comparing the second insulation value with the expected insulation value, and generating a sensor external insulation detection result based on the comparison result.

[0056] Among them, if the second insulation value is less than the expected insulation value, there is an external insulation abnormality of the sensor.

[0057] An error range can be set to determine whether the ratio of the second insulation value to the expected insulation value is within the error range. If it is within the error range, the external insulation of the sensor is normal. If it is not within the error range and the ratio is less than 1, the external insulation of the sensor is abnormal and corresponding measures need to be taken.

[0058] After detecting the abnormality of the external insulation of the sensor, the first signal transmitted by the signal line can be collected to determine whether there is an obvious error in the first signal, and the external insulation detection result of the sensor can be verified twice. If there is an obvious error in the first signal, it is judged that the external insulation detection result of the sensor is correct, and an insulation abnormality has occurred on the outside of the underwater sensor. If there is no obvious error in the first signal, the detection pulse voltage is sent to the second spare core wire again to obtain the second insulation value on the second spare core wire, and the second insulation value is compared with the expected insulation value to generate a secondary sensor external insulation detection result. If the secondary sensor external insulation detection result still does not show an insulation abnormality, it is determined that an insulation abnormality has occurred on the outside of the underwater sensor.

[0059] Step S2024: Generate an insulation detection result based on the sensor internal insulation detection result and the sensor external insulation detection result.

[0060] If one of the sensor internal insulation test result and the sensor external insulation test result is insulation abnormality, the insulation test result is insulation abnormality.

[0061] When the insulation detection result shows insulation abnormality, isolation measures can be taken to prevent the fault from further expanding, where the isolation measures can include isolating underwater sensors, etc.

[0062] When the insulation detection result is insulation abnormality, the data transmitted by the signal line in the previous time period can also be detected to determine whether there is data abnormality or the like.

[0063] In some optional implementations, when the first insulation value is less than the expected insulation value, the sensor internal insulation detection result is that the sensor internal insulation is abnormal.

[0064] In some optional implementations, when the second insulation value is less than the expected insulation value, the sensor external insulation detection result is that the sensor external insulation is abnormal.

[0065] By comparing the insulation value with the expected insulation value and determining whether the insulation test result is abnormal, the test efficiency can be improved.

[0066] In some optional implementations, when the insulation detection result shows that the insulation is abnormal, the connection between the underwater sensor and the multi-core watertight cable is disconnected.

[0067] In case of insulation abnormality, disconnecting the circuit can ensure the safety of underwater equipment.

[0068] The underwater sensor insulation detection method provided in this embodiment generates an insulation detection result by comparing the insulation value and the expected insulation value, and can quickly obtain the deviation between the insulation value and the expected insulation value, so as to facilitate the subsequent timely measures.

[0069] In this embodiment, a method for detecting insulation of an underwater sensor is provided, and the method is applied to an insulation detector in an underwater data cabin; the underwater data cabin and the underwater sensor are connected by a multi-core watertight cable; the multi-core watertight cable includes a signal line and a spare core line; in the underwater data cabin, the spare core line passes through the lower part of the underwater data cabin and is connected to the insulation detector. Figure 3 : is a flow chart of an underwater sensor insulation detection method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0070] Step S301, sending a detection pulse voltage to the spare core wire, and detecting the insulation value on the spare core wire.

[0071] For details, please see Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0072] Step S302, generating an insulation detection result according to the insulation value on the spare core wire.

[0073] For details, please see Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0074] Step S303, transmitting the insulation detection result to the monitoring system to generate an insulation detection report of the underwater sensor.

[0075] The transmission method of the insulation test result is not limited, and it can be transmitted by wire or by wireless transmission. After obtaining the insulation test result, data analysis can be performed on it, and the data analysis can include abnormality detection, fault diagnosis, etc.

[0076] The underwater sensor insulation detection method provided in this embodiment transmits the insulation detection result to the monitoring system, and can centrally manage the data to facilitate subsequent data analysis.
