[0031] The core of the present invention is to provide an electronic fence, which is easier to store, carry, install and use than the existing rope-woven fence.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Figure 1 A schematic diagram of connecting an electronic fence provided by an embodiment of the present invention; Figure 2 A schematic diagram of the fence post structure of an electronic fence provided in an embodiment of the present invention.

[0034] like Figure 1 As shown, the electronic fence provided by the embodiment of the present invention includes a plurality of fence posts 101, an infrared detector 102, a processor 103 connected to the infrared detector 102, and an alarm 104 connected to the processor 103;

[0035] Among them, the infrared detector 102 includes an infrared transmitter 1021 and an infrared receiver 1022 respectively arranged on two fence posts 101 and respectively connected to the processor 103; the processor 103 is used to control the infrared transmitter 1021 to transmit infrared signals, and control the alarm 104 to alarm when the infrared receiver 1022 does not receive the infrared signal.

[0036] In the specific implementation, Figure 2 As shown, the signal transmitting end of the infrared transmitter 1021 is arranged on the outer surface of the fence stake 101, and the signal receiving end of the infrared receiver 1022 is arranged on the outer surface of another fence stake 101. Only one infrared transmitter 1021 or one infrared receiver 1022 can be arranged on one fence stake 101, or an infrared transmitter 1021 can be arranged in one direction and an infrared receiver 1022 can be arranged in another direction, or multiple infrared transmitters 1021 or multiple infrared receivers 1022 can be arranged, and the arrangement can be flexible according to specific needs.

[0037] Since there is no hardware connection between the fence posts 101, a processor 103 may be provided for each fence post 101. The fence post 101 may be a conical tube structure, which is convenient for stacking and carrying.

[0038] In actual application, after a group of fence stakes 101 each provided with an infrared transmitter 1021 and an infrared receiver 1022 are placed adjacent to each other, the fence stake 101 is rotated to make the infrared transmitter 1021 and the infrared receiver 1022 face each other, and then the control circuit of the electronic fence is energized, so that the infrared signal transmitted between the infrared transmitter 1021 and the infrared receiver 1022 plays the role of a rope for enclosure. When someone passes between this group of fence stakes 101, the processor 103 controls the alarm 104 to send out an alarm signal, thereby playing the role of reminding that the fenced area is originally reminded by the rope. Compared with the rope fence in the prior art, the electronic fence provided by the embodiment of the present invention only needs to carry multiple fence stakes 101, and there is no need to organize the ropes, so it is easy to store, carry, install and use.

[0039] The electronic fence provided by the embodiment of the present invention includes, in addition to a plurality of fence posts, an infrared detector, a processor connected to the infrared detector, and an alarm connected to the processor; wherein the infrared detector includes an infrared transmitter and an infrared receiver respectively arranged on two fence posts and respectively connected to the processor; the processor is used to control the infrared transmitter to transmit an infrared signal, and when the infrared receiver does not receive the infrared signal, the alarm is controlled to alarm. The electronic fence provided by the embodiment of the present invention is applied, after a group of fence posts respectively provided with an infrared transmitter and an infrared receiver are arranged adjacently, the infrared transmitter and the infrared receiver are made to face each other by rotating the fence posts, so that the infrared signal transmitted between the two plays the role of a rope for enclosure, when someone passes between the group of fence posts, the processor controls the alarm to send an alarm signal, thereby playing the role of reminding that the fenced area originally reminded by the rope is here, and compared with the rope fence in the prior art, the electronic fence provided by the embodiment of the present invention only needs to carry a plurality of fence posts, and there is no need to arrange the rope, so it is easy to store, carry and install and use.

[0040] By using the electronic fence provided in the above embodiment, multiple electronic fences can be used to form a fence around the construction area. However, when someone accidentally touches the fence post 101 or deliberately moves the fence post 101, the range of the fence will be changed, resulting in the risk of electric shock when unrelated personnel mistakenly enter the construction area that does not belong to the fence area formed by the moved fence post 101. Therefore, based on the above embodiment, the electronic fence provided in the embodiment of the present invention also includes:

[0041] A displacement detection sensor provided on the fence post body 101 and connected to the processor 103;

[0042] Correspondingly, the processor 103 is also used to control the alarm 104 to sound an alarm after the displacement detection sensor detects that the fence stake 101 is displaced.

[0043] In actual application, after the staff places the fence post 101, the control circuit of the electronic fence is powered on or the lock mode is set, the displacement detection sensor starts working. If the fence post 101 is moved, it will send a signal to the processor 103, and the processor 103 will control the alarm 104 to sound an alarm.

[0044] On the basis of the above-mentioned embodiment, the alarm 104 can specifically adopt a voice alarm 104. Furthermore, the voice alarm 104 includes a serial communication module connected to the processor 103, a voice chip module connected to the serial communication module, and a speaker connected to the voice chip module. The serial communication module is used to transmit the binary alarm signal sent by the processor 103 through the GPIO pin after the alarm mechanism is triggered to the voice chip module, and the voice chip module converts the binary alarm signal into a voice signal and transmits it to the speaker for voice broadcast. An alarm voice is set in advance in the voice chip module or the processor 103, such as: "Stop, high voltage danger", "You have entered a high voltage danger area, please evacuate quickly", etc.

[0045] In addition, the alarm 104 may also be an audible and visual alarm 104. In practical applications, if the fence pile 101 is moved after the staff leaves the construction site, an audible and visual alarm signal is issued.

[0046] The above two types of alarms 104 can be used in combination. It is understandable that other types of alarms 104 can also be provided.

[0047] Since some construction tasks are carried out at night, workers often need to temporarily build lighting facilities. To facilitate night work, based on the above embodiments, the electronic fence provided in the embodiment of the present invention also includes a lighting circuit arranged on the outer surface of the fence pile 101 and connected to the processor 103.

[0048] In a specific implementation, the lighting circuit can be started by a switch or automatically started, that is, the electronic fence provided by the embodiment of the present invention can further include a photoresistor connected to the processor 103;

[0049] Correspondingly, the processor 103 is also used to control the lighting lamp of the lighting lamp circuit to light up when the ambient light intensity value detected by the photoresistor is lower than a preset value.

[0050] The lighting lamp in the lighting lamp circuit can be a light strip, which is wound around the outer surface of the fence post body 101.

[0051] The electronic fence provided in the embodiment of the present invention also includes a lighting circuit. When workers need to carry out construction at night, there is no need to provide additional lighting facilities, and emergency repair work can be carried out quickly, saving workload.

[0052] Furthermore, the electronic fence provided by the embodiment of the present invention also includes:

[0053] A camera connected to the processor 103 and a wireless communication module connected to the processor 103;

[0054] Correspondingly, the processor 103 is also used to send the surveillance video captured by the camera to a designated address via the wireless communication module.

[0055] In a specific implementation, the wireless communication module may specifically be a Wi-Fi module, a GSM communication module, or the like.

[0056] The processor 103 receives the surveillance video and alarm information taken by the camera and sends it to a designated address, such as a smart terminal (mobile phone, tablet or host computer, etc.) through the wireless communication module. It can also be used to receive configuration parameters sent by the smart terminal, such as protection range, lighting brightness, etc., and adjust the local configuration according to the configuration parameters.

[0057] Optionally, the electronic fence provided by the embodiment of the present invention may further include a human-computer interaction device for allowing staff to view and adjust configuration parameters of the electronic fence.

[0058] Furthermore, the electronic fence provided by the embodiment of the present invention also includes:

[0059] A power supply module connected to the processor 103 .

[0060] In a specific implementation, since the processor 103, lighting circuit and other electronic components all need power supply, in order to save time for arranging the construction site, the electronic fence provided in the embodiment of the present invention also includes a power supply module for supplying power to the processor 103 and other electrical components. The power supply module can be a power conversion module for converting the mains power into the working voltage of the processor 103 and other components, or it can be a battery module. For example, the power supply module can adopt a photovoltaic power generation module, and a solar cell panel can be set on the outer surface of the fence pile body 101, so that electricity can be stored during the day to provide power for the operation of the system, thereby eliminating the need for a separate power supply.

[0063] The infrared detector 102 includes an infrared transmitter 1021 formed by a routing resistor R1 and a light-emitting diode in series, and an infrared receiver 1022 formed by a routing resistor R2 and a photoresistor in series. The infrared receiver 1022 converts the received infrared signal into an electrical signal and inputs it into the INT1 pin of the processor 103 through an amplifier.
