Figure 1 , the distribution network line video monitoring device includes:

[0067] Current mutual induction power supply device 1, locking device 2, main control module 4, transmission module 5, camera module 6 and packaging shell 7;

[0068] The main control module 4, the transmission module 5 and the camera module 6 are arranged in the package shell 7;

[0069] The current mutual induction power supply device 1 includes an opening and closing portion 11, a fixing portion 12, and a torsion spring portion 13. The fixing portion 12 and the camera module 6 are respectively fixed on opposite sides of the enclosing shell 7; the torsion spring portion 13 is used to connect the opening and closing portion 11 and the fixing portion 12; a first groove is provided on the first surface of the opening and closing portion 11 near the fixing portion 12, and the first groove passes through the opening and closing portion 11 in a direction parallel to the first surface; a second groove is provided on the second surface of the fixing portion 12 near the opening and closing portion 11, and the second groove passes through the fixing portion 12 in a direction parallel to the second surface; the first groove and the second groove are arranged opposite each other and form a cable slot 14; the distribution network line video monitoring device is fixed to the cable through the cable slot 14, and the cable passes through the cable slot 14;

[0071] The locking device 2 is used to lock the position of the opening and closing part 11 and the fixing part 12 after the opening and closing part 11 and the fixing part 12 are combined;

[0072] The main control module 4 is electrically connected to the locking device 2, and is used to receive a locking control signal and send a locking control signal to the locking device 2;

Then, the cable of the distribution network line is placed in the second groove of the fixing part 12, and the force applied to the opening and closing part 11 is stopped.

The remote control device can be a remote control device. If the transmission device 5 receives the lock control signal sent by the remote control device, it will transmit the lock control signal to the main control module 4.

[0101] Specifically, under the condition that the cables of the distribution network line are operating normally, the current mutual inductance power supply device 1 generates an induced current through electromagnetic induction and transmits the induced current to the power control conversion module 3. The power control conversion module 3 converts the received induced current into a first direct current and transmits the first direct current to the main control module 4 to power the main control module 4. At the same time, the main control module 4 can control the first direct current to power the transmission module 5, the camera module 6 and the locking device 2.

[0107] The secondary winding coil 17 is electrically connected to the power control conversion module 3 , and is used to transmit the induced current generated by electromagnetic induction to the power control conversion module 3 .

[0108] Specifically, when the cables in the distribution network line are operating normally, current will pass through the cable slot 14, forming a primary winding coil in the silicon steel ring 16. At this time, a current induction magnetic field is formed in the silicon steel ring 16, and then the secondary winding coil 17 induces an induced current of corresponding proportion in the silicon steel ring 16, and transmits the induced current generated by electromagnetic induction to the power control conversion module 3. The power control conversion module 3 converts the received induced current into a direct current to power the main control module 4, and powers the transmission module 5, the camera module 6 and the locking device 2 through the main control module 4.

[0109] Further, Figure 6 This is a schematic diagram of the structure of a main control module provided according to an embodiment of the present utility model. Figure 6 , the main control module includes a first DC conversion unit 41, a control unit 42 and a switch unit 43;

[0112] Specifically, the main control module receives a portion of the first DC current output by the power control conversion module 3, and performs voltage reduction processing on the first DC current through the first DC conversion unit 41 to generate a second DC current to power the control unit 42, wherein the voltage corresponding to the first DC current is 3.3V; if the remote control device controls the distribution network line video surveillance device to work normally, the control unit 42 controls the switch unit 43 to open, so that the power control conversion module 3 supplies power to the transmission module 5, the camera module 6 and the locking device 2; if the remote control device controls the distribution network line video surveillance device to enter a sleep state, the control unit 42 controls the switch unit 43 to close, so that the power control conversion module 3 stops supplying power to the transmission module 5, the camera module 6 and the locking device 2.

[0119] The camera acquisition board 61 is used to convert the received on-site processing information into a scene signal, and transmit the scene signal to the background control center through the main control module 4 and the transmission module 5.

[0120] Specifically, if it is necessary to remotely control the camera module 6 to capture on-site scene information, the remote control device will send a camera control signal to the transmission device 5. After receiving the camera control signal, the transmission device 5 transmits the camera control signal to the main control module 4. The main control module 4 controls the camera to capture on-site scene information through the camera acquisition board 61 according to the camera control signal, wherein the on-site scene information includes on-site scene image information and on-site scene video information.

After the battery module 8 receives the battery power supply signal sent by the main control module 4, it supplies power to the main control module 4 and supplies power to the locking device 2, the transmission module 5 and the camera module 6 through the main control module 4; if the distribution network line is in a normal output state, when the remote control device controls the distribution network line video surveillance device to enter a sleep state, the main control module 4 sends a battery charging signal to the power control conversion module 3.
