Description

Safety protection system and safety protection method for uninterrupted operation site of power distribution network Technical Field The invention belongs to the technical field of safety operation of power systems, and particularly relates to a safety protection system and a safety protection method for a power distribution network uninterrupted operation site. Background In the uninterrupted operation (also called live working) process of the power distribution network, in order to ensure the safety of operators and passers-by, a safety fence needs to be arranged around an operation area so as to isolate a definite operation forbidden zone and prevent irrelevant personnel from entering a high-voltage dangerous area by mistake. At present, tools such as an insulating conical barrel, a fixed insulating fence and a warning belt are commonly adopted for manual layout on site. The prior art has the following defects: 1) The transportation, arrangement, adjustment and withdrawal of the fence are completely dependent on manpower, time and labor are consumed, and in high-strength or complex terrain operation, the manpower dependency is higher, the efficiency is lower, and the layout quality and speed are affected. 2) Once laid, the protective area is fixed. If the core risk point is displaced (such as an adjusting arm support of an insulating arm car) in the operation process, the static fence cannot be dynamically adjusted along with the displacement, the protection is static and passive, the adaptability is poor, and the protection area and the risk area are possibly mismatched, so that a safety blind area is formed or the public area is excessively occupied. 3) The safety monitoring mainly depends on the visual guardian, the monitoring mode is original, and risks of distraction, visual fatigue and response delay exist. Especially, dead zones and delay exist at night or in severe weather, the monitoring effect is greatly reduced, and all-weather and dead-angle-free real-time early warning cannot be realized. 4) For the intrusion behavior, the misjudgment or dispute is easy to generate depending on subjective judgment of personnel. Meanwhile, the implementation conditions (such as the arrangement range of the fence and the alarm event) of the safety measures lack objective and continuous digital records, and are inconvenient for accident tracing, management and optimization. 5) The traditional fence is only used as a physical isolation barrier, has a single function, and cannot give out early warning before the environmental condition is deteriorated to threat the operation safety. Disclosure of Invention In order to solve the problems of static and passive protection, poor adaptability and dependence on guardianship in the existing fence, the invention provides a safety protection system and a protection method for a power distribution network uninterrupted operation site. In order to achieve the above purpose, the present invention adopts the following technical scheme: In a first aspect, the invention provides a safety protection system for an uninterrupted operation site, comprising an integrated control center and at least two intelligent fence units; The intelligent fence unit comprises a movable base, a telescopic insulating fence body, a movable base and a movable base, wherein the movable base is provided with autonomous movement capability; The integrated control center is in communication connection with the two intelligent fence units and comprises a controller, wherein the controller is configured to control the movable bases of at least two intelligent fence units to cooperatively move to a preset position and control the telescopic insulating fence body to be unfolded to form a closed operation area; The system further comprises: the safety monitoring module is arranged on the telescopic insulating fence body or the integrated control center, and is used for carrying out multi-dimensional safety monitoring on the operation area and the periphery and generating corresponding monitoring signals; the audible and visual alarm is arranged on the telescopic insulating fence body or the integrated control center; The controller is further configured to receive the monitoring signal sent by the safety monitoring module, judge whether the monitoring signal indicates that effective safety risk occurs, and control the audible and visual alarm to alarm and send remote alarm information when the effective safety risk is confirmed. The effective security risk at least comprises personnel security risk caused by illegal intrusion and operation security risk caused by over-limit of on-site environment parameters. Further, the safety monitoring module comprises an infrared sensing sub-module, which is used for detecting illegal intrusion behaviors in the working area and generating intrusion trigger signals. Further, the safety monitoring module comprises an environment sensing sub-module, which is used for collec
