Referring to fig. 1, an embodiment of the present application provides a distributed online temperature monitoring system applied to a power supply loop, where the power supply loop is connected to a plurality of ring main units 100, and the monitoring system includes: a plurality of monitoring units 200 and a data analysis terminal 300.
The plurality of monitoring units 200 are respectively in one-to-one correspondence with the plurality of ring main units 100, each monitoring unit 200 comprises a temperature measurement module 210 for monitoring the temperature of a cable joint in the corresponding ring main unit 100, an acquisition module 220 for acquiring temperature data of the temperature measurement module 210, and a display module 230 for displaying the temperature data, and the temperature measurement module 210, the acquisition module 220 and the display module 230 are sequentially connected. The data analysis terminal 300 is respectively in communication connection with the display module 230 and the plurality of acquisition modules 220, and achieves distributed monitoring on the plurality of ring main units 100 by acquiring the plurality of temperature data.
It should be noted that there may be multiple power supply loops in this application, and each power supply loop may be connected to multiple ring main units 100, and distances between multiple ring main units 100 may be equal or different. In addition, for each ring main unit 100, the number of cable connectors arranged inside may be one, or may be multiple; correspondingly, the number of the temperature measuring modules 210 in each ring main unit 100 can also be one or more. Based on this, each monitoring unit 200 may be composed of one temperature measuring module 210, one collecting module 220, and one display module 230, or may be composed of a plurality of temperature measuring modules 210, a plurality of collecting modules 220, and a plurality of display modules 230, and the number of the temperature measuring modules 210, the collecting modules 220, and the display modules 230 in the monitoring unit 200 is not limited in the present application.
For ease of understanding, the decision logic of the data analysis terminal 300 will be described below with a specific example:
in this example, the number of the power supply loop is one, three ring main units (respectively marked as a first ring main unit, a second ring main unit and a third ring main unit) are connected in the power supply loop, three cable connectors (a connector 1, a connector 2 and a connector 3) are arranged in each ring main unit, each monitoring unit corresponding to each ring main unit respectively comprises three temperature measuring modules, one collecting module and one display module, and the three temperature measuring modules respectively monitor the temperatures of the three cable connectors. In addition, the number of the data analysis terminals is one, and the data analysis terminals are respectively in communication connection with the three monitoring units.

Meanwhile, the data analysis terminal can send the abnormal data to the display module for on-site display, so that technicians can conveniently check the abnormal data.
It should be further noted that when the data analysis terminal analyzes each temperature data, the data analysis terminal may perform a judgment according to a preset threshold or a preset range, for example, when the threshold is 10 ℃ or the preset range is set to be 8 ℃ to 10 ℃, the temperature data of the first cabinet 1 connector is monitored to be 50 ℃, the temperature data of the second cabinet 1 connector and the third cabinet 1 connector are both 28 ℃, and the difference between the two is greater than the threshold or the preset range, that is, the first cabinet 1 connector is determined to be abnormal; however, if the difference between the two is smaller than the threshold or the preset range, the first cabinet 1 connector is considered to be in a normal state.
