Example 1:
the embodiment 1 of the invention provides a monitoring and warning system for floor power distribution equipment.
As shown in fig. 1, a monitoring and warning system for a floor power distribution device includes a microprocessor, a monitoring module, an image acquisition module, a warning module, and a communication module.
The microprocessor is used as a control center of the system, controls the operation of each module and processes the information transmitted by each module. The monitoring module adopts a high-precision millimeter wave radar, and can monitor a moving target in an area in real time and determine the spatial position of the target. The image acquisition module adopts a plurality of image acquisition devices for acquiring image information of a target in an area, and the number of the image acquisition devices in the embodiment is four. The warning module comprises a rotary warning lamp, a high-power loudspeaker and a ground projection device with a rotating function. In this embodiment, the rotary warning light, the high-power speaker and the ground projection device are all disposed above the floor power distribution equipment, and may also be disposed on a bracket or other position near the floor power distribution equipment as needed, which is not limited in the present invention. The communication module is used for realizing communication between the system and the power grid monitoring terminal, can send daily monitoring data and alarm information to the monitoring terminal, and can also receive a control instruction and a voice signal sent by the monitoring terminal.
Further, in this embodiment, an identity verifier is further disposed near the ground of one image acquisition device, and is used for verifying the identity by swiping a card or swiping a face of a worker when the worker is mistakenly recognized or not recognized by the system and a false alarm occurs.
As shown in fig. 2, in the monitoring and warning system for floor power distribution equipment provided by the present invention, three regions are defined in a peripheral range of a floor power distribution equipment 4, which are a monitoring region 1, an identification region 2 and a risk region 3, respectively, and the sizes of the three regions can be flexibly adjusted according to actual needs, but it is required to ensure that the area of the monitoring region 1 is larger than the area of the identification region 2 and larger than the area of the risk region 3; the monitoring area 1 and the risk area 3 are concentric circular areas, and the circle center is located in the center of the ground projection of the floor type power distribution equipment; the identification area 2 is a regular polygon area, each corner is provided with an image acquisition device, and the number of the image acquisition devices is four in the embodiment, so that the identification area 2 is square, and the centroid of the square coincides with the centers of the monitoring area 1 and the risk area 3.
Further, in order to reduce the disturbance to the passers-by, the areas of the identification area 2 and the risk area 3 are not set to be excessively large.
When the system runs, the millimeter wave radar monitors the monitoring area 1 for 24 hours, no abnormal event occurs in the monitoring area 1, namely when the mobile target is not monitored, the system is in a standby mode, except the millimeter wave radar, other modules are in a low-power-consumption standby state, or one or more image acquisition devices can be started as required to carry out video monitoring.
When the radar monitors that a moving target appears in the monitoring area range, the system is switched to the running mode, and the module in the low-power consumption standby state is started. The radar continuously monitors the position of the moving target, and when the moving target is only located in the monitoring area 1 and does not enter the identification area 2, the rotary warning lamp is turned on to remind that important facilities exist in the position, but other actions are not executed, so that excessive disturbance on passers-by passing normally is prevented.
When the radar monitors that the moving target enters the identification area 2, the image acquisition device can acquire the image information of the moving target. On one hand, the microprocessor collects the face information of the moving target according to the two image collecting devices closest to the moving target, and compares the face information with the face information of the staff stored in the database to determine whether the moving target is the staff of the power grid; if a plurality of moving targets exist in the area, the face information of each target is respectively collected and compared. When at least one of the moving targets is identified as a power grid worker, no alarm is given, and a comparison result is sent to a power grid monitoring terminal; when all the targets are non-working personnel, illegal invasion is judged, at the moment, a loudspeaker plays a voice warning to remind the invading personnel that dangerous equipment exists in the front of the invading personnel, and the invading personnel please keep away from the dangerous equipment immediately, and meanwhile, the system sends a blue warning signal to the power grid monitoring terminal through the communication module. And on the other hand, drawing the motion track of the intruder, and judging the risk of the intruder according to the stay time and the motion track.
The method for acquiring and comparing the face information by the image acquisition device adopts the prior art.
In addition, if the system fails to correctly identify the worker, a false alarm occurs, and the worker can verify the identity on the identity verifier by swiping a card or by swiping a face. After the identity authentication is finished, the identity authentication device displays that the identity authentication is successful, and the alarm is relieved. Meanwhile, the system packs the identity verification information and the collected face information and sends the identity verification information and the collected face information to the power grid monitoring terminal, and the worker can add the collected face information into the database after verification is correct, so that the database is perfected, and the accuracy of subsequent identification is improved.
When the system is in a voice alarm state and the radar monitors that the intruder continues to enter the risk area 3, the system sends a yellow warning signal, the speaker plays a warning whistle to warn, and meanwhile the microcontroller controls the ground projection device to rotate to the direction towards the intruder according to the position of the intruder acquired by the radar. As shown in fig. 3, after the intruder 7 enters the risk area 3, the microprocessor controls the ground projection device 6 to rotate towards the direction of the intruder according to the position of the intruder determined by the radar, projects warning characters and images on the ground where the intruder 7 is located, and warns the intruder to immediately get away; meanwhile, a red line is projected behind the person and is overlapped with the boundary line of the risk area 3 defined by the system, and the intruder is guided to retreat behind the red line. When the intruder retreats to the red line, namely leaves the risk area 3 and retreats to the identification area 2, the loudspeaker stops playing the alarm whistle and plays the voice warning again, the ground projection device 6 stops projecting after the set time (such as 20 seconds), and the microprocessor positions and continuously monitors the position of the intruder through radar and draws a motion track until the intruder leaves the identification area 2.
If the intruder does not leave the risk area 3 within a period of time (such as 30 seconds) after the ground projection device 6 is started, or the intruder continues to approach the floor power distribution equipment 4, the system sends a red warning signal to the power grid monitoring terminal to warn the staff that high-risk personnel approach the equipment.
Further, staff's accessible communication module and monitoring module at electric wire netting monitoring terminal department acquire scene image information in real time, also can remotely control turning to of image acquisition device and ground projection arrangement, can also remind the invador to keep away from through the long-range propaganda directed to communicate of speaker at any time.
