Example 2
As shown in fig. 4, the present invention further provides a method for monitoring the state of a cable line in real time based on intelligent big data analysis, which comprises:
the collecting unit 1 respectively collects real-time data of cable line states sent by M rows of collecting terminals 4, N rows of each row of collecting terminals 4 sequentially send collected data to the back row from the first row until the collecting terminal of the N row obtains data of 1 to N-1 rows, and finally the collecting terminal of the N row sends the data of the collecting unit 1 and the data of 1 to N-1 rows to the collecting unit 1;

For example, cable load temperatures of 30-50℃are normal. The allowable temperature values of the cables of different types are also different, for example, the crosslinked polyethylene insulated cable can resist the long-term temperature of 90 ℃, and the polyvinyl chloride insulated cable can resist the long-term temperature of only 70 ℃. When the sensor detects temperatures exceeding 10% of these normal temperatures, the fault registration is located at level 3; when the sensor detects temperatures exceeding 20% of these normal temperatures, the fault registration is located at level 2; when the sensor detects temperatures exceeding 30% of these normal temperatures, the fault registration is located at level 1. This is similar in principle with respect to real-time current of the cable, ambient gas concentration. The fault level is 1 level, an instruction for immediate maintenance is sent, the fault level is 2 level and 3 level, and an instruction for time-limited maintenance is sent.

The cable line status real-time data includes cable ground and run current data, cable joint conductor temperature, cable surface temperature, cable fire data, cable ambient gas data, cable flooding data, cable disconnection data.
When the cable grounding and running current data are collected, the high current (more than 5A) can be collected near the cable joint through a current transformer, and the low current can be achieved by designing a current sampling circuit (such as a current sampling resistor) on a sampling terminal. Meanwhile, the open circuit and the short circuit of the cable can be collected through current monitoring of the cable.
The temperature of the cable joint conductor is collected by installing a temperature sensor at the cable joint; the surface temperature of the cable can be acquired by installing temperature sensors on the surface of the cable at intervals of 30 meters, and 3 sensors can be arranged at intervals of 10 meters to acquire the surface temperature of the cable.
Cable fire data is collected through setting up smoke transducer or flame sensor near the cable wiring, and cable peripheral gas data is collected through setting up gas sensor (such as CO, CO2, NO, NO2, NH3, SO2, CH4 etc. toxic gas sensor module) near the cable wiring, can monitor whether the cable takes place the spontaneous combustion that all kinds of causes lead to.
Whether the cable is immersed data is monitored by arranging an immersed sensor at the cable wiring position.
The real-time data of the cable line state comprises cable grounding and running current data, cable joint conductor temperature, cable surface temperature, cable fire data, cable peripheral gas data, cable water immersion data and cable disconnection data, and any one or any data monitoring is abnormal, so that the fault signal can be sent out from small to large by triggering the corresponding fault indication lamp of the acquisition terminal to be lightened, the acquisition terminal to alarm and the matrix area of the collecting unit to be positioned. Specific fault data are finally sent to the cloud platform server, the cloud platform server can directly send monitoring data to a terminal of maintenance personnel, such as a mobile phone provided with monitoring software, the monitoring data comprise the position of a slice region where a fault cable is located (namely a positioning module positioning region integrated by a collecting unit), the fault type (such as overcurrent, disconnection or overhigh temperature), and the maintenance personnel can quickly and accurately position the fault cable information by combining fault data prompt of an intelligent terminal and on-site warning signals (buzzing alarm and indicator lights).
