Description
Technical Field
The invention belongs to the technical field of monitoring and controlling of intelligent power grids, and particularly relates to an intelligent monitoring and controlling system for a high-voltage power grid on a prison perimeter.
Background
The protection measures of the current prison system are most common in that a peripheral perimeter high-voltage power grid is used for completing protection work, but the current prison high-voltage power grid only has high-voltage protection and does not have intelligent alarm prompt, namely, when artificial damage occurs, the high-voltage power grid cannot send out an alarm signal so as to timely inform an attendant; besides the protection of the high-voltage power grid, guard-on-duty continuous guard patrol is also needed. Meanwhile, there are also the following disadvantages:
1. the technology is old, and only a pure transformer is used for generating a high-voltage line; is easy to be damaged by technical criminals, and can not give an alarm even if an object touches the net or is damaged.
2. The operation cost is high, and because the high-voltage power grid does not have the alarm function, in order to realize the alarm function, a lot of other auxiliary devices need to be added, so that the operation cost is increased. In bad weather, because the voltage on the power grid is fixed and unchangeable, especially in humid, fog and rainy seasons, the moisture in the air is in a saturated state, and the impedance between the power grid electrodes becomes small, so that the power consumption becomes large. Is not favorable for energy conservation and results in low economic benefits.
3. The operation state record of the power-free network, especially the alarm event and the power-off condition of the power network, is not favorable for the responsibility of the problem after the incident.
4. The false alarm frequency is high, and false alarm sometimes occurs. Because the power grid system does not effectively link with devices such as camera monitoring and infrared rays, and is easily influenced by surrounding environments, such as the movement of animals and plants, false alarm signals are often triggered.
In summary, because the existing high-voltage power grid prevention and control system has the defects, certain difficulty is brought to safety protection of the important places, and effective protection and supervision cannot be realized, so that a new way is needed to improve the current high-voltage power grid protection to meet the needs of specific occasions.
