Embodiment 1
[0039] Such as figure 1 As shown: this embodiment provides an online monitoring platform for the underground cable channel of the urban power grid, including a monitoring center 1 and a mobile monitoring unit 2 connected to it, and the mobile monitoring unit 2 includes an overhead track set in the cable trench 6. The mobile mechanism 13 provided on the overhead track 6, the monitoring terminal 4 is provided on the mobile mechanism 13, and the monitoring terminal 4 includes a sensor module 15, a control module 12, a video monitoring module 14 and a first communication module 3, The moving mechanism 13 is also provided with a positioning device 5, an ultrasonic mouse repeller 16 and an insect dispelling device 11, the positioning device 5 is connected with the monitoring center 1, and the sensor module 15 includes a temperature sensor, a humidity sensor, an open flame sensor , a combustible gas sensor and a water level sensor, the control module 12 is connected to the sensor mod...
Embodiment 2
[0043] Such as Figure 2 to Figure 4 As shown: the difference from Embodiment 1 is that the ultrasonic mouse repeller 16 and the disinsection device 11 are connected to the control module 12, and the disinsection device 11 adopts an electric shock type disinsection lamp.
[0044] The water level sensor 33 is arranged on one side of the moving mechanism 12 through a lifting mechanism. The lifting mechanism includes a lifting motor 31 arranged on the moving mechanism 12. The winding reel 32 connected to the lifting motor 31 by transmission, the suspension rope 36 provided on the winding reel 32 , and the water level sensor 33 is provided at the lower end of the suspension rope 36 .
[0045] Described video monitoring module 14 comprises the miniature cloud platform 28 that is arranged on described moving mechanism 13, and infrared camera 29 and infrared thermal imager 30 are arranged on described miniature platform 28, and described miniature platform 28 and described control mo...
Embodiment 3
[0050] Such as Figure 5 and Figure 6 Shown: its difference with embodiment one is:
[0051] The positioning device 5 includes a wire groove 19 provided on the overhead track 6, an elastic support mechanism 18 at the bottom of the wire groove 19, and a distributed optical fiber vibration sensor 17 arranged on the upper surface of the elastic support mechanism 18. The top of the distributed fiber optic vibration sensor 17 is higher than the top of the trunking 19 , and the distributed fiber optic vibration sensor 17 is connected to the monitoring center 1 . When the wheels of the traveling mechanism walk on the overhead track, they press the distributed optical fiber vibration sensor arranged on the overhead track, and the distributed optical fiber grating sensor deforms, and the position of the traveling mechanism is monitored through the light information received by the monitoring center.
[0052]It is realized by the distributed optical fiber vibration sensor set on the ...
