[0045] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 should fall within the scope of protection of the present invention.

[0046] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0047] Figure 1 is a schematic diagram of the structure of a fence body and a detection module provided according to an embodiment of the present invention. Figure 2 1 is a connection diagram of an electronic fence system provided according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the electronic fence system includes: a fence body 1, a detection module 2, a display module 3 and a control module 4;

[0048] The detection module 2 is arranged on the fence body 1, and includes an infrared transmitting unit 21 and an infrared receiving unit 22; the infrared receiving unit 22 is electrically connected to the control module 4; the control module 4 is in communication connection with the display module 3;

[0049] The infrared emitting unit 21 is used to emit the detection light 20 to the infrared receiving unit 22; the infrared receiving unit 22 receives the detection light 20 and converts it into a current signal and inputs it into the control module 4;

[0050] The control module 4 is used to determine the voltage range of the detection light 20 according to the detection current signal and output a display signal to the display module 3 according to the voltage range, so that the manager can adjust the relative position of the infrared receiving unit 22 and the infrared transmitting unit 21 according to the display information of the display module 3.

[0051] The fence body 1 may be a portable mobile fence, and the detection module 2 is disposed on the fence body 1. The detection module 2 is used to perform intrusion detection based on the area enclosed by the fence body 1, so the detection area of ​​the detection module 2 needs to surround the area enclosed by the fence body 1. For example, Figure 1 As shown, the fence body 1 includes a movable post 11 and a fence line 12. The fence line 12 is arranged between the movable posts 11 to form a fence area. The detection module 2 can be arranged on the movable post 11. The detection module 2 includes an infrared transmitting unit 21 and an infrared receiving unit 22. The infrared transmitting unit 21 and the infrared receiving unit 22 can be respectively arranged on two movable posts 11 connected by a single fence line 12. The infrared transmitting unit 21 emits a detection light 20 to the infrared receiving unit 22 to ensure that intrusion detection can be performed at each fence line 12, thereby ensuring the accuracy of the detection of the electronic fence system.

[0052] in, Figure 3 is a circuit connection diagram of a display screen provided according to an embodiment of the present invention, such as Figure 3 As shown, the display module 3 may include a display screen, and the information output by the display screen can be intuitively received by the management personnel.

[0053] Among them, the control module 4 is connected to the detection module 2 and the display module 3 respectively, and the infrared transmitting unit 21 and the infrared receiving unit 22 are respectively set on the fence body 1, and the infrared transmitting unit 21 is controlled to emit the detection light 20 to the infrared receiving unit 22. When the positions of the infrared transmitting unit 21 and the infrared receiving unit 22 correspond, that is, when they are aligned, the intensity of the received detection light 20 is the largest, and the corresponding voltage signal is the largest. When there is a deviation between the positions of the infrared transmitting unit 21 and the infrared receiving unit 22, the intensity of the received detection light 20 becomes smaller, and the corresponding voltage signal also becomes smaller. According to this principle, combined with the control module 4 and the display module 3, it is judged whether the setting positions of the infrared transmitting unit 21 and the infrared receiving unit 22 are reasonable.

[0054] Specifically, the infrared transmitting unit 21 emits the detection light 20 to the infrared receiving unit 22, the infrared receiving unit 22 receives the detection light 20 and converts it into a current signal and inputs it into the control module 4, the control module 4 converts the current signal into a voltage signal and determines the voltage range of the voltage signal, and after determining the corresponding voltage range, outputs the display signal corresponding to the voltage range to the display module 3, and after the display module 3 displays the information, the management personnel can adjust the relative positions of the infrared transmitting unit 21 and the infrared receiving unit 22 according to the displayed information.

[0055] Exemplarily, the control module 4 recognizes that the range of the voltage signal is 0-3.3V voltage signal, and divides the 0-3.3V voltage signal into 10 voltage ranges. Table 1 shows the relationship between the voltage range and the display information of the display module 3. The display information of the display module 3 corresponding to the voltage range is shown in Table 1. After the control module 4 determines the range corresponding to the current detection voltage signal, the display module 3 outputs the corresponding display information. When the value of the display information is less than 6, it means that the detection voltage signal is too small at this time, which affects the accuracy of intrusion detection. The management personnel need to adjust the relative position of the infrared receiving unit 22 and the infrared transmitting unit 21 to ensure that the infrared receiving unit 22 can receive as much detection light 20 of the infrared transmitting unit 21 as possible under normal circumstances to ensure the accuracy and reliability of the detection result.

[0059] The technical solution of the embodiment of the present invention is to set a detection module, a display module and a control module in the electronic fence system, and make the control module output different display signals according to different detection light voltage ranges, and the display module displays different information according to different display signals, so that the management personnel can judge whether the detection position of the infrared transmitting unit and the infrared receiving unit is accurate according to the display information of the display module, thereby ensuring the accuracy and reliability of the operation of the electronic fence system.

[0060] Optional, Figure 4 is a circuit connection diagram of a duty cycle control circuit provided according to an embodiment of the present invention, combined with Figure 2 and Figure 4 As shown, the control module 4 includes a duty cycle control circuit 41 and a main control chip 42;

[0061] The duty cycle control circuit 41 is electrically connected to the infrared receiving unit 22 and the main control chip 42, respectively, and is used to receive the detection current signal and convert the detection current signal into a standard current signal and input it into the main control chip 42; wherein the standard current signal is a signal that can be recognized by the main control chip 42;

[0062] The main control chip 42 is used to receive the standard current signal to determine the voltage range of the detection light 20 and output a display signal to the display module 3 according to the voltage range.

[0063] Among them, since the specifications of the main control chip 42 are fixed and the size of the received and identified current signal is fixed, a duty cycle control circuit 41 is set to convert the detected current signal into a standard current signal that can be recognized by the main control chip 42. The duty cycle control circuit 41 can control the duty cycle of the pulse square wave to adjust the current signal output by the infrared receiving unit 22. Exemplarily, the duty cycle control circuit 41 may include a GP8102 chip, and the range of the infrared receiving unit 22 outputting the current signal when the duty cycle is in the range of 0-100% is 4-20mA.

[0064] The main control chip 42 may be a microcontroller, the operating frequency may be 64MHz, and it may have functions such as read protection, write protection, DMA, etc. The main control chip 42 may include a communication interface, a digital-to-analog conversion unit, a connection channel, a clock chip, a control duty cycle timer, a general 16-bit timer, a watchdog timer, and a system timer.

[0065] Specifically, the duty cycle control circuit 41 receives the detection current signal of the infrared receiving unit 22 and adjusts the duty cycle to convert the detection current signal into a standard current signal and inputs it into the main control chip 42. The main control chip 42 receives the standard current signal and determines the standard voltage signal of the standard current signal, and then determines the voltage range corresponding to the detection light 20.

[0066] The technical solution of the embodiment of the present invention ensures the normal operation of the electronic fence system by setting a duty cycle control circuit and a main control chip in the control module and adjusting the detection current signal to a standard current signal recognizable by the main control chip by using the duty cycle control circuit.

[0067] Optional, Figure 5 is a circuit connection diagram of a sensor signal detection circuit provided according to an embodiment of the present invention, combined with Figure 2 and Figure 5 As shown, the control module 4 also includes a sensor signal detection circuit 43;

[0068] The sensor signal detection circuit 43 is electrically connected to the duty cycle control circuit 41 and the main control chip 42 respectively, and is used to receive the standard current signal and convert the standard current signal into a standard voltage signal and input it into the main control chip 42;

[0069] The main control chip 42 is used to determine the voltage range of the detection light 20 according to the standard voltage signal and output a display signal to the display module 3 according to the voltage range.

[0070] The sensor signal detection circuit 43 can convert the standard current signal into a standard voltage signal and input it into the main control chip 42 so that the main control chip 42 can process and judge it. For example, the 4-20mA standard current signal can be converted into a 0-3.3V standard voltage signal that the main control chip 42 can recognize.

[0071] In some embodiments, the sensor signal detection circuit 43 further includes a voltage follower, a subtractor, and a non-inverting amplifier formed by an operational amplifier.

[0072] Specifically, the duty cycle control circuit 41 receives the detection current signal of the infrared receiving unit 22 and adjusts the duty cycle to convert the detection current signal into a standard current signal and inputs it into the sensor detection circuit. The sensor detection circuit converts the standard current signal into a standard voltage signal that can be recognized by the main control chip 42 and inputs it into the main control chip 42. The main control chip 42 receives the standard voltage signal and determines the voltage range of the standard voltage signal, and controls the display information of the display module 3 according to the voltage range.

[0073] The technical solution of the embodiment of the present invention ensures the normal operation of the electronic fence system by setting a sensor signal detection circuit in the control module and adjusting the standard current signal to a standard voltage signal that can be recognized by the main control chip by using the sensor signal detection circuit.

[0074] Optional, continue to refer to Figure 2 As shown, the control module 4 further includes an intrusion detection circuit 44 and a main control chip 42; the intrusion detection circuit 44 is electrically connected to the infrared receiving unit 22 and the main control chip 42 respectively;

[0075] The intrusion detection circuit 44 is used to output a trigger signal to the main control chip 42 when the infrared receiving unit 22 does not receive the detection light 20;

[0076] The main control chip 42 is used to output an intrusion signal according to the trigger signal.

[0077] Among them, the intrusion detection circuit 44 can be composed of a trigger chip. When an intrusion occurs, the detection light 20 is blocked, and the intensity of the detection light 20 received by the infrared receiving unit 22 is 0 or very weak. The infrared receiving unit 22 outputs a level signal to the intrusion detection circuit 44. The intrusion detection circuit 44 outputs a trigger signal to the main control chip 42 according to the level signal, so that the main control chip 42 outputs an intrusion signal to alert the management personnel.

[0078] It is understandable that the intrusion detection circuit 44 can be electrically connected to each infrared receiving unit 22 separately and individually, and when one or more infrared receiving units 22 are blocked and have no detection light 20, a trigger signal can be output through the intrusion detection circuit 44.

[0079] In some embodiments, since the infrared receiving unit 22 and the infrared transmitting unit 21 include multiple groups, each group is set at a different position. When the corresponding infrared receiving unit 22 does not receive the detection light 20, it means that the corresponding position has been invaded. The control unit can output different intrusion signals according to the position of the infrared receiving unit 22 to improve the accuracy of electronic fence intrusion detection.

[0080] The technical solution of the embodiment of the present invention is to set up an intrusion detection circuit. When the detection area of ​​the electronic fence system is invaded, the infrared receiving module receives no detection light and outputs a level signal to the intrusion detection circuit. The intrusion detection circuit outputs a trigger signal to the main control chip to prompt the main control chip that the area has been invaded, so as to facilitate the staff to timely judge the intrusion information of the detection area and deal with emergencies in time.

[0083] The alarm transmitting unit 51 is used to receive an intrusion signal and output an alarm signal to the alarm receiving unit 52 .

[0084] The alarm module 5 includes an alarm transmitting unit 51 and an alarm receiving unit 52 . The alarm transmitting unit 51 and the main control chip 42 can be connected to each other by using the RS-485 communication protocol. The alarm transmitting unit 51 is also connected to the alarm receiving unit 52 by communication.

[0085] Specifically, when the infrared receiving unit 22 receives no detection light 20, the main control chip 42 outputs an intrusion signal to the alarm transmitting unit 51, and the alarm transmitting unit 51 outputs an alarm signal to the alarm receiving unit 52. The alarm receiving unit 52 can be a device for real-time reception by management personnel, such as a mobile phone, a computer, an audible and visual alarm, etc. The alarm receiving unit 52 responds and transmits the alarm signal to the management personnel so that the management personnel can understand the detection situation in time and deal with it.

[0086] In some embodiments, since the infrared receiving unit 22 and the infrared transmitting unit 21 include multiple groups, each group is set at a different position. When the corresponding infrared receiving unit 22 does not receive the detection light 20, it means that the corresponding position has been invaded. The control unit can output different intrusion signals according to the position of the infrared receiving unit 22, and the alarm transmitting unit 51 outputs different alarm signals according to different intrusion signals. The alarm signal may include the position information of the corresponding detection module 2, so that the management personnel can receive the position of the intrusion for timely positioning and inspection and processing.

[0087] The technical solution of the embodiment of the present invention is to set an alarm transmitting unit and an alarm receiving unit in the alarm module so that the alarm module can respond promptly when there is an intrusion, so that the management personnel can deal with the emergency in time and ensure the accuracy of the electronic fence system detection.

[0089] Among them, the alarm transmitting unit 51 is also connected to the display module 3 for communication, and can output the alarm signal to the display module 3. The display module 3 can output alarm information, which may include parameters such as the intrusion location, time, and intrusion range, so as to improve the efficiency of the management personnel's processing.

[0090] The technical solution of the embodiment of the present invention connects the alarm transmitting unit and the display module by communication, so that the alarm transmitting unit can output the alarm signal to the display module, so that the display module can display the alarm information in time, thereby improving the efficiency of management personnel in handling.

[0091] Optional, continue to refer to Figure 2 As shown, the electronic fence system also includes a power module 6;

[0092] The power module 6 is electrically connected to the control module 4 and is used to supply power to the control module 4 .

[0093] Among them, the power supply module 6 may include a power conversion circuit, the power conversion circuit includes a -5V power output circuit and a 3.3V power output circuit, the -5V power output circuit can be electrically connected to the operational amplifier in the control module 4, and the 3.3V power output circuit can be electrically connected to the main control chip 42 in the control module 4 to supply power to the main control chip 42, thereby ensuring the normal operation of the control module 4.

[0094] Based on the same inventive concept, Figure 6 is a flow chart of a first method for controlling an electronic fence system according to an embodiment of the present invention, Figure 1 , Figure 2 and Figure 6 As shown, an embodiment of the present invention further provides a control method of an electronic fence system, which is applied in the electronic fence system;

[0099] Among them, when the positions of the infrared emitting unit 21 and the infrared receiving unit 22 correspond, that is, when they are aligned, the intensity of the received detection light 20 is maximum and the corresponding voltage signal is maximum. When there is a deviation between the positions of the infrared emitting unit 21 and the infrared receiving unit 22, the intensity of the received detection light 20 becomes smaller and the corresponding voltage signal also becomes smaller.
