DETAILED DESCRIPTION

In the drawings or descriptions, similar or identical parts use the same reference numerals, and in actual applications, the shape, thickness or height of each component may be enlarged or reduced. The embodiments listed in the present invention are only used to illustrate the present invention and are not used to limit the scope of the present invention. Any obvious modifications or changes made to the present invention do not depart from the spirit and scope of the present invention.

[0026] See also Figure 1-2 In one embodiment of the present invention, a remote monitoring device for electric power automation equipment includes: Control center 10; The monitoring module 20 is composed of a plurality of monitoring units and is used to transmit the real-time monitoring images of the scene to the control center 10. Each of the monitoring units includes a base 201, a monitoring camera 203 installed on the base 201 and movable on the plane of the base 201, and a driving mechanism for driving the monitoring camera 203 to move; The sensor module 30 is composed of a plurality of sensors for detecting different parameters, and is used to detect environmental parameters at the site and operating parameters of the power equipment. The position information corresponding to the plurality of sensors is recorded in the control center; When the parameter detected by at least one of the sensors exceeds a threshold, the control center marks the position information corresponding to the sensor to obtain the target area, and sends a driving instruction to the driving mechanism to move at least one of the monitoring cameras 203 to a position where the target area can be monitored.

[0027] For the sake of convenience of example, it is assumed that the operating temperature threshold of device A on site is 40 degrees Celsius. When the corresponding sensor detects that the operating temperature of device A exceeds 40 degrees Celsius, it sends a signal to the control center 10, and the control center 10 obtains the corresponding target area position according to the detection target of the sensor. Then the control center 10 sends a driving instruction to the monitoring module 20. After receiving the driving instruction, the driving mechanism can drive the monitoring camera 203 to move, so as to obtain the monitoring picture of the target area. In this way, it can ensure that the operator can obtain the abnormal information in the first time, thereby ensuring work safety and avoiding the timeliness of the operator obtaining abnormal information due to the existence of blind spots.

[0028] See also Figure 2-4 In one embodiment of the present invention, the driving mechanism includes a moving seat 202 and a mounting seat 211, wherein the moving seat 202 is slidably arranged in the front groove of the base 201 and can move back and forth in the vertical direction, a vertical screw rod 204 threadedly connected to the moving seat 202 is arranged in the front groove of the base 201, the vertical screw rod 204 is rotatably connected in the front groove of the base 201, and the vertical screw rod 204 is driven by a vertical driving motor 205 installed on the base 201; the monitoring camera 203 is installed on the mounting seat 211, the mounting seat 211 is slidably arranged in the groove of the moving seat 202 and can move back and forth in the horizontal direction, a transverse screw rod 206 threadedly connected to the mounting seat 211 is arranged in the groove of the moving seat 202, the transverse screw rod 206 is rotatably connected in the groove of the rotating seat 202, and the transverse screw rod 206 is driven by a transverse driving motor 207 installed on the moving seat 202.

[0029] During operation, the vertical drive motor 205 drives the vertical screw rod 204 to rotate, thereby driving the moving seat 202 to move vertically, and the horizontal drive motor 207 drives the horizontal screw rod 206 to rotate, thereby driving the mounting seat 211 to move horizontally, thereby realizing the planar movement of the monitoring camera 203 on the base 201.

A sensing strip adapted to the sensor 215 is fixed on the groove wall on the back of the base 201, and the sensing strip includes a vertical sensing strip 216 and a horizontal sensing strip 217, an alarm 210 is also installed on the base 201, and the alarm 210 is electrically connected to the sensor 215 and the sensing strip. When the sensor 215 moves to a position where it senses the sensing strip, the alarm 210 sends an alarm message to the control center 10. In actual use, it is possible that a surveillance camera 203 moves to the maximum vertical or horizontal stroke and still cannot monitor the target area. This alarm design allows the staff to understand the situation and make corresponding processing.

A guide surface 225 corresponding to the protrusion 222 is provided on the top of the rotating portion 221, and the guide surface 225 is an arc surface. When in use, the tail of the sub-buckle 218 is inserted into the female buckle 219, and the protrusion 222 contacts the guide surface 225 to drive the rotating portion 221 to rotate, and the spring 223 is compressed. After the support surface 224 contacts the sub-buckle 218, the spring 223 recovers, thereby completing the buckle. When the buckle needs to be contacted, the sub-buckle 218 only needs to be pulled upward.

[0036] The working principle of the present invention is: In summary, in the embodiment of the present invention, by setting a monitoring device composed of a control center 10, a monitoring module 20 and a sensor module 30, it is possible to ensure that the staff can obtain effective monitoring images in real time when an abnormal situation occurs on site, thereby ensuring work safety and avoiding the existence of blind spots that affect the timeliness of the operator's acquisition of abnormal information; By providing a driving mechanism consisting of the moving seat 202 and the mounting seat 211, the plane movement of the monitoring camera 203 can be achieved, which greatly expands the monitoring range; By providing the sensor 215 and the sensor bar, when the monitoring camera 203 moves to the maximum vertical or horizontal travel and still cannot monitor the target area, the staff can understand the situation and make corresponding treatment; The base 201 is connected to the mounting surface by providing a snap-fit ​​structure, so that the monitoring unit can be disassembled for easy maintenance and management.
