DETAILED DESCRIPTION

[0023] like Figure 1-3 As shown, the utility model provides an electronic fence device, the physical structure of the fence includes a fence composed of a supporting column 1 and a guardrail net arranged between the supporting columns 1, and the electronic fence device is also provided with a signal acquisition unit and a background execution unit, the supporting column includes a hollow column 3, a floating trigger mechanism arranged in the column 3, an opening arranged on the side of the column 3 and corresponding to the floating trigger mechanism, and a fixing plate 8 arranged in the opening, the outer end of the fixing plate 8 is fixed to the guardrail net, and the inner end is connected to the floating trigger mechanism, and the floating trigger mechanism includes a fixing plate 8 arranged in the fixing plate 8. An upper spring 4 and a lower spring 5 in the column 3, a suspension column 6 vertically arranged in the column 3 and fixed between the upper spring 4 and the lower spring 5, a fixing frame 7 fixed on the suspension column 6, and a ring plate 9 arranged in the column 3 and respectively located between the upper spring 4, the lower spring 5 and the fixing frame 7, the suspension column 6 is spaced from the inner wall of the column 3, a plug hole is arranged on the ring plate 9 and the plug hole is larger than the outer diameter of the suspension column 6, the suspension column 6 is inserted into the plug hole of the ring plate 9 and is spaced from the ring plate 9, the outer diameter of the fixing frame 7 is larger than the inner diameter of the plug hole of the ring plate 9, and the inner end of the fixing plate 8 is fixed to the fixing frame 7;

[0024] The support column 1 is a hollow columnar structure, and each fixing plate 8 corresponds to a group of floating trigger mechanisms. The upper and lower ends of the suspension column 6 are respectively installed in the support column 1 through the upper spring 4 and the lower spring 5. The suspension column 6 does not contact the support column 1. The inner end of the fixing plate 8 is fixed to the suspension column 6 through the fixing frame 7, and the outer end of the fixing plate 8 extends out from the opening on one side of the column body 3. The guardrail net is fixed on the outer end extending out of the fixing plate 8. The ring plate 9 is fixed to the inner wall of the support column 1 and does not contact the suspension column 6 located in the socket. When the guardrail net moves up or down after being subjected to force, the suspension column 6 is driven to move up or down synchronously through the fixing plate 8. The fixing frame 7 on the suspension column 6 contacts the ring plate 9 after synchronous displacement, and the circuit is connected to trigger the alarm. The design has a simple structure, a stable structure, and a low cost, and effectively reduces the probability of false touches and false alarms. At the same time, even if a person wearing insulating clothes and gloves climbs over the fence, an alarm will be triggered, further improving the safety protection performance.

[0025] like Figure 4As shown, in order to realize the electronic monitoring function, a signal acquisition unit and a background execution unit are added to the electronic fence device, wherein the signal acquisition unit includes a press-trigger sampling structure, that is, when a person presses the fence net, the pressure switch sampling terminal K1 will be turned on, and then a voltage divider will be formed through the first voltage divider resistors R1 and R2, so that the input terminal level of the control chip U1 changes, and the control chip U1 inputs the output control signal to the single-chip microcomputer U2 through the wireless transmission module U3 and the wireless receiving module U4, and the single-chip microcomputer U2 outputs the control signal to the stepper motor X of the camera and the alarm module U5, wherein the alarm module U5 can be an audible and visual alarm. The control chip U1 can also use, for example, an infrared detection chip, a human body sensing chip, etc., that is, it can sense the surrounding people or moving objects by other means.

[0026] Of course, when the human body does not press the fence but just touches it, an alarm will also occur. That is, through the designed touch switch sampling terminal K2, once the human body touches the fence, the fence conducts electricity and forms a current loop between the human body and the ground. The control chip U1 can detect the current at this time and then output a control signal.

[0027] The utility model can also be applied to an electronic fence system composed of multiple fences. Since a signal acquisition unit is set in each fence, when a suspicious behavior occurs, the camera needs to be linked to monitor the image data at that time. This requires the use of encoder U6. When an abnormality occurs in a certain electronic fence, the pre-set encoder U6 encoding value will be sent to the background execution unit together with the control signal of the control chip U1. After decoding, the single-chip microcomputer U3 can know which fence has the abnormality, and then control the camera's stepper motor X to rotate through the set program to align with the electronic fence where the abnormality occurs.

[0028] like Figure 2 As shown, a sealing gasket is provided on the opening on one side of the column 3 , and a vertical opening adapted to the fixing plate 8 is provided on the sealing gasket.

[0029] The sealing gasket can effectively protect against dust and rain and increase the service life.

[0030] like Figure 1 As shown, a mounting base 10 is provided at the lower end of the column 3. The mounting base 10 can be easily installed, and the mounting base 10 has a fixing hole, which can be fixed by bolts or rivets.

[0031] like Figure 1 As shown, the fence net includes a frame 11 and a grid 2 arranged inside the frame 11. The fence net has a simple structure, low deadweight and low cost.

[0032] like Figure 1-2As shown, a group of floating trigger mechanisms or multiple groups of floating trigger mechanisms arranged up and down are arranged on the inner wall of one side of the column 3.

[0033] like Figure 1-2 As shown, a group of floating trigger mechanisms or multiple groups of floating trigger mechanisms arranged up and down are arranged on the inner walls of the two opposite sides of the column 3.

[0034] According to the required length of the electronic fence in actual use, there are multiple support posts 1, and the fence net between the support posts 1 is fixed by a fixing plate 8. Each fixing plate 8 corresponds to a set of floating trigger mechanisms. The support posts 1 at the starting end and the terminal end only need to be provided with a fixing plate 8 and a corresponding floating trigger mechanism on one side, and the support posts 1 between the starting end and the terminal end need to be provided with a fixing plate 8 and a corresponding floating trigger mechanism on both opposite sides.

[0035] When the support column 1 is fixed on the ground, the lower end of the support column 1 is fixed to the installation base 10, and the installation base 10 is fixed to the ground by bolts and anchors. When the starting end and / or the end end of the electronic fence is a wall, the support column 1 is directly embedded in the wall of the wall for internal fixation, and the installation base 10 is not required.
