In practical application, for example, the monitoring server may include a plurality of camera monitoring devices and a plurality of alarms, and the monitoring server may select a server configured correspondingly according to the number of the camera monitoring devices; when the number of the camera monitoring devices reaches hundreds or more, the monitoring server can select a Hadoop distributed computing server cluster comprising a plurality of distributed computing servers, so that the computing capability is further improved; the High fault tolerance and the High reliability of the PC are realized, the mass data can be stored, meanwhile, the parallel computing software framework map/Reduce can be well combined, and High Throughput (High Throughput) data access is provided for the application program.

Further, the monitoring server, as shown in fig. 3, includes an obtaining module 31, a processing module 32, a determining module 33, and an alarm module 34.

Specifically, after all types of equipment in the field are installed, the position and the shape of the camera monitoring equipment of the system are fixed for a long time, and favorable conditions are provided for the algorithm of the background model. The monitoring server utilizes an algorithm for extracting foreground moving objects by dynamic background modeling relative to the video and can utilize an interframe difference method to compare the difference of two or more static images so as to realize the detection of illegal crossing security electronic fence personnel and non-constructors.

Firstly, acquiring one or more background templates in a relatively unchanged background environment, then analyzing a factual image of a construction area drawn in an image area, and acquiring an image in real time when detecting whether illegal spanning security electronic fence personnel and non-construction personnel exist in the environment, such as an acquisition module; the processing module is used for eliminating light intensity and shadow of the image, and then the judging module is used for calculating the difference of pixels or areas of the processed image and the background template one by one. And when the difference result is full of a certain image area, the collected image is considered to be inconsistent with the template, and the suspected person appears in the collected image.

On the basis, in order to avoid the influence on diagnosis caused by the change of a fixed object in a monitoring range, such as the sway of branches, the change of a building window and the like, displacement test is carried out on a changed area, and when a suspected person is found to move for a certain distance in a certain time and cross over the boundary of the electronic fence, the person is considered to cross over the fence; and the alarm module sends alarm information to the alarm and simultaneously takes a snapshot.

Furthermore, the image processing technology can be simultaneously utilized to identify the safety helmet of the constructor, when the constructor is found not wearing the safety helmet in the construction area, the constructor is considered to enter the construction area, the system sends alarm information, and simultaneously the image is captured. And on the basis, the snapshot is sent to the mobile phone of the manager, for example, through a 4G network.

Taking the environment of the power construction transformer substation as an example, when the system judges that the hidden danger of foreign matter invasion exists, a manager can be reminded to pay attention in time, and therefore accurate judgment of foreign matter invasion of the transformer substation is achieved.

The processing method of the intelligent electronic fence system, referring to fig. 4, includes:

s41, determining a security electronic fence area in the monitored image;

s42, acquiring a live video image in real time;

s43, comparing the video image with a preset background picture, and calculating a difference area; the preset background picture is a periodically acquired background picture;

and S44, when the difference area is larger than a preset threshold value and the displacement track of the pixel point in the difference area is crossed with the safety electronic fence area, judging that someone violates the crossing of the electronic fence.

In the step S41, after the system is installed in place, determining the security electronic fence area according to the monitoring picture; for example, when a foreign object invades the area, the following steps are carried out: when the pixel points of the foreign matters are crossed with the edge pixel points of the safe electronic fence area, the situation that the foreign matters enter a construction site or cross the fence is judged.

In step S42, live video images are acquired in real time, that is: firstly, identifying personnel at the periphery of the security electronic fence by the system; in the steps S43-S44, the collected video image is compared with a preset background picture, and the difference area is calculated by adopting an interframe difference method in the comparison process; the method comprises the steps of presetting a background picture, wherein the preset background picture is a periodically collected background picture; for example, after the system is installed, one or more background templates are collected from a relatively unchanged background environment; later, when the background environment is changed and relatively stable, a new image can be additionally acquired as a background template.

For example, the calculated difference area is set to 200 pixels according to the monitoring range, the parameters of the camera and the size of the personnel.

Then, tracking and analyzing the motion trail of the security electronic fence, namely judging that when more than 200 pixel points change, the changed points are gathered together, and indicating that suspected personnel are around the security electronic fence; when the movement track of the person crosses the wiring of the security electronic fence, the accident of crossing the security electronic fence without authorization occurs. The method can accurately judge whether a person violates the rule to cross the electronic fence, and has high intelligent degree; the method is convenient and quick, and realizes monitoring of key areas.

Further, as shown in fig. 4, the method further includes:

and S45, when judging that the electronic fence is crossed illegally by a person, sending alarm information to an alarm, and recording a current image.

In another embodiment, the method may further include:

analyzing the on-site video image and judging whether a constructor wears a safety helmet or not;

when a constructor who does not wear the safety helmet exists, alarm information and a recorded image are sent out.

Further, still include: and sending the result of judging whether the electronic fence is crossed by a person in violation to the monitoring mobile terminal.

The processing method of the intelligent electronic fence system is implemented, for example: firstly, one or more background templates are collected in a relatively unchangeable background environment and used as background templates, then, factual image analysis is carried out on construction areas drawn in image areas, and when whether illegal persons crossing a security electronic fence or non-construction persons exist in the environment or not needs to be detected, an image and the background templates are collected in real time to carry out pixel-by-pixel or area difference calculation.

And when the difference result is full of a certain image area, the collected image is considered to be inconsistent with the template, and the suspected person appears in the collected image. On the basis, in order to avoid the influence of the change of a fixed object (such as the shake of branches, the change of a building window and the like) in the monitoring range on diagnosis, displacement test is carried out on a changed area, wherein the moving distance refers to the moving distance of a pixel point, which means a certain displacement in video monitoring; finally, the moving distance is compared with the electronic fence specified in the background image in the monitoring.

When the suspected person moves a certain distance within a certain time and crosses the boundary of the electronic fence, the person is considered to cross the fence, alarm information is sent out, and meanwhile, an image is captured. Meanwhile, the safety helmet of the constructor is identified by utilizing an image processing technology. The specific process of identification, such as according to the specific color, yellow, red, etc. of the safety helmet, can be analyzed by the prior art color identification technology whether the safety helmet is worn or not.

When the safety helmet is found not worn in the construction area, the non-constructors are considered to enter the construction area, the system sends alarm information, and meanwhile, images are captured. On the basis, the monitoring server can also send the judgment information and the snapshot image to the mobile phone of the manager through the 4G network. And reminding a manager to pay attention so as to accurately judge the foreign matter invasion of the transformer substation, wherein the whole monitoring process is shown in fig. 5.

As can be seen from fig. 5, the work flow of the whole system is:

the method comprises the steps of firstly, periodically collecting background pictures to avoid the occurrence of a false judgment phenomenon of foreign matter invasion caused by the change of the background pictures, then, collecting the pictures in real time, processing light intensity and shadow of the pictures, calculating a difference area between a specified area and the background pictures through comparison with the background pictures, considering that people crossing an electronic fence exist around the pictures when the difference area is larger than a set value, then, analyzing the displacement of the difference area, considering that the phenomenon of crossing the electronic fence in violation exists when a displacement track crosses the electronic fence, sending alarm information by a system, and simultaneously shooting and uploading images of the people in violation.

Meanwhile, the system monitors the state of a safety helmet worn by constructors in the defined electronic fence area, and when the constructors who do not wear the safety helmet are found, the system sends alarm information, shoots illegal personnel and sends images to the mobile phone end of a manager. The specific monitoring process can be identified according to the color of the safety helmet.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
