[0002] In actual production, work and life applications, protection zones (isolation zones) need to be established in many scenarios to protect the safety of life, property and equipment, and the protection zones may span multiple geographical locations; for example, in the electrical engineering test process, the pressurized equipment is at the outlet bushing, and the electrical connection part may load the test voltage to other electrical connection equipment (such as other outlet intervals, busbars, etc.), and these devices may not be in the same working area. In the past, fences were used to isolate the entrances and exits, and special personnel were sent to guard them, which consumed a lot of manpower and material resources, and due to unexpected factors, it was easy for people or small animals to enter the pressurized area in the blind spot of vision, causing losses to personnel, equipment, etc. Summary of the invention

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0034] In live working, test working, working at height and other operations that require isolating the working area, setting up warning areas and isolation areas is a necessary step; the conventional way now is to isolate the protection area by setting up warning belts, isolation fences or setting up manual squatting. The conventional isolation method has the following main disadvantages: 1. Manual squatting consumes a large number of workers, especially when the isolation area spans different locations (such as substations or cable line high-voltage tests, etc.), it is necessary to set up supervisors at different locations; 2. The isolation belt or fence is troublesome to set up, and it takes a lot of time to install and recycle. In actual operations, it cannot be dried in time after being exposed to the sun and rain, and there is a lot of damage and loss. A large number of fences need to be configured when there are multiple points or large-scale operations, which is a waste of manpower and material resources; 3. Conventional fences have no warning functions such as sound and light, and staff must observe the warning area at any time and give voice reminders; if there are blind spots in the field of vision, people or animals can easily enter the isolation area by mistake, and when small animals invade the isolation area, the staff are not frightened in time and it may not work; 4. No matter which method is used to set up the isolation area, it is inevitable that animals or objects will invade the protection area; conventional isolation methods require staff to take protective measures (such as powering off and grounding the tested equipment and other protective operations) when this happens, and manual operation has a certain delay; the present invention can take linkage protection measures in time when foreign objects invade the protection area (such as cutting off the test power supply within milliseconds), which can effectively reduce or even eliminate personnel and equipment losses.

[0035] Therefore, it is of great significance to apply it to working environments such as live and high-voltage testing that require the establishment of isolation areas.

[0036] Therefore, the present invention aims to overcome the shortcomings of the prior art, provide a fence device for warning, expulsion and protection, solve the various drawbacks of using fences and manually dividing isolation zones in operations that require the establishment of isolation zones, deepen the application, and greatly facilitate operations such as live working and high-voltage testing that require the division of isolation protection zones.

[0037] This embodiment 1 provides an electronic warning fence railing, such as Figure 1-Figure 2 As shown, it includes a rod body with adjustable length. The rod body with adjustable length here is a prior art, and can refer to an adjustable pneumatic rod, etc., which will not be described here. The connection between the rod body and the ground is also detachable, and a support ear can be set at the bottom of the rod body, and the rod body is fixed to the ground by screws passing through the support ear.

[0038] The basic function of an electronic fence is to isolate and protect the protected area, replacing the commonly used safety fences, warning tapes and other protective isolation methods. Therefore, the rod body of the present invention adopts a retractable column design, and the weight of a single column design is controlled within 10KG, which is convenient to carry and does not take up a large space.

[0039] The rod body is detachably connected with a warning device, wherein the detachable connection may be a magnetic connection, a buckle connection, or a threaded connection.

[0040] Modules are connected by magnetic attraction, snap-on or threaded connections, and can be quickly assembled. Soft connections and detachable electrical nodes are used between modules for power and signal connections. When the modules are removed, the electrical connections between the modules are automatically disconnected, which makes the fence railing more flexible.

[0041] The warning device includes a warning unit for displaying a warning area on the ground and monitoring whether there is an intruder in the warning area, a drive-away unit for displaying a drive-away area on the ground and monitoring whether there is an intruder in the drive-away area, and a protection unit for displaying a protection area on the ground and monitoring whether there is an intruder in the protection area. The warning unit, the drive-away unit, and the protection unit are all connected to an alarm module via a control module, and the warning unit and / or the drive-away unit and / or the protection unit are also connected to an execution module for executing a protection action for equipment in the protection area via the control module, and a power supply module supplies power to the warning unit, the drive-away unit, and the protection unit.

[0042] The fence railing adopts a modular design as a whole. The pole body adopts a columnar design. The corresponding warning device can be selected and installed on the upper part of the pole body according to the actual working environment. The middle part of the pole body adopts a retractable rod design to adjust the height of the fence pole body. The module is adjusted according to the visual angle range to adjust the range of the warning area and the expulsion area.

[0043] In some embodiments, the power supply module and the control module may be directly mounted on the pole body or may be mounted in other places.

[0044] In this embodiment, a power module is provided at the bottom of the rod body for powering the entire device. The power module is specifically a battery and an external power supply interface. At the same time, a linkage condition output physical interface is provided. The interface adopts an aviation plug and a terminal for signal output (a connection port between the execution module and the control module). The middle section of the rod body is provided in the shape of an upper and lower telescopic rod for adjusting the height of the fence. The upper part of the rod body is assembled with detachable modules (warning unit, expulsion unit and protection unit) selected according to the actual situation on site. In this embodiment, the control module is not installed on the rod body. In order to facilitate the layout, the warning unit, the expulsion unit and the protection unit in this embodiment are connected to the control module through a wireless transmission module. Figure 4-5As shown, therefore, the modules that can be detachably installed on the pole body include a warning unit, a drive-away unit, a protection unit, a wireless transmission module, etc. The wireless transmission module can be a wifi module or a bluetooth module (it can also be a radio frequency shortwave, etc.), which is used to receive or send device control signals for remote control linkage. Of course, even if the control module is not installed on the pole body, the warning unit, the drive-away unit and the protection unit can also be connected to the control module through wires.

[0045] In some embodiments, an environment monitoring module is further included, and the environment monitoring module is connected to the alarm module and the execution module through the control module. The environment monitoring module can be installed on the rod body or not. Similarly, no matter where the environment monitoring module is installed, the environment monitoring module and the control module can also be connected by wire or wirelessly.

[0046] In some embodiments, from outside to inside, there are warning area, evacuation area, and operation area. Figure 3 As shown, correspondingly, on the rod body, a protection module, a drive-away module and a warning module are arranged from bottom to top.

[0047] In some embodiments, the warning unit includes a warning display module for displaying a warning area on the ground and a warning monitoring module for monitoring whether there is an intruder in the warning area; the expulsion unit includes an expulsion display module for displaying an expulsion area on the ground and an expulsion monitoring module for monitoring whether there is an intruder in the expulsion area; the protection unit includes a protection display module for displaying a protection area on the ground and a protection monitoring module for detecting whether there is an intruder in the protection area.

[0048] In some embodiments, the warning display module, the expulsion display module, and the protection display module include but are not limited to one or more combinations of a projector or a display screen, and if the warning display module, the expulsion display module, and the protection display module are display screens, the display screen is used to display prompt information of the area where the intruder is located.

[0049] When it is a projector, the warning display module, the expulsion display module, and the protection display module are installed on the railing; when it is a display screen, the display screen is installed on the ground near the railing.

[0050] The display module can be considered as a device on the electronic fence, but the output device is not limited to the projector. For example, when the electronic fence is used in mountainous areas or grasslands, if a projector is used for warning notification, the displayed text may not be clear; in this case, laser projection can be used to divide different areas (i.e. only mark the line), but the warning information can be displayed by other means such as a display, LED screen, etc.

[0051] When each display module is displaying, it can be distinguished by different colors and different logos, and the color and logo settings of each display module can be set by the control module, which is convenient for more application scenarios.

[0052] In some embodiments, the warning monitoring module, the expulsion monitoring module, and the protection monitoring module include but are not limited to one or more combinations of infrared detectors, radar wave detectors, video monitors, electromagnetic detectors, ultrasonic detectors, or X-ray detectors.

[0053] In some embodiments, the environmental monitoring module includes but is not limited to one or more of a temperature and humidity monitor, a wind speed monitor, a light monitor, and an electromagnetic field strength monitor.

[0054] Different environmental monitoring modules are designed according to the on-site use environment, protection object, climate environment, and required input and output requirements, and the environmental monitoring modules are selected according to the use requirements.

[0055] Through functional module design, it has a wider range of applications, and the module can be selected according to the actual situation on site, the protection object and the functions to be achieved.

[0056] The basic version of the present invention is roughly divided into three areas (the number and range of areas can be increased or decreased according to the actual use scenario), and the display module in each area emits a laser projection. In the warning area, a cordon is drawn in a specific area, and warning text (such as: "Warning area, do not cross" "High voltage danger") or patterns and other contents are projected on the cordon. At the same time, the corresponding monitoring module (infrared reflection (counter-radiation), radar wave reflection, video dynamic monitoring and other principles) is used to monitor the biological characteristics and displacement characteristics of this area (the specific monitoring characteristics are selected according to the actual site); when an animal or object invades the warning area, the warning monitoring module gives a trigger signal to the control module, and the control module controls the alarm module to emit an audible and visual alarm to prompt the intruder to quickly move away; the warning area refers to the prevention of accidental entry.

[0057] If the intruder continues to invade after the warning area is triggered, it will enter the expulsion area; the operating principle of the expulsion area is similar to that of the warning area; the expulsion area can set up high-decibel alarms, mechanical expulsion, strong light expulsion and other measures according to actual conditions; in order to achieve the function of scaring and driving away the intruder, the expulsion area refers to preventing small animals and other low-IQ creatures from accidentally entering.

[0058] If the intruder continues to invade after the expulsion area is triggered, it will enter the protection area; the protection area can adjust and select the corresponding protection monitoring module according to the actual situation on site or the defense object. The principle is similar to the warning area and the expulsion area. The basic version generally uses infrared counter-shooting and warning fences for physical warnings; if the protection area is breached, the execution module is controlled to start the protection linkage to execute the protection action; the output of the protection action result includes but is not limited to disconnecting the test power supply, forcing the high-voltage equipment to be powered off and grounded, or notifying the staff; the protection area refers to preventing intruders or environmental conditions from reaching an emergency situation where they have reached damage to personnel and equipment, to prevent accidents.

[0059] The above are three defense zones set up as the basic version. You can increase or decrease, or replace modules according to the actual application environment to increase or decrease the number of defense zones and the number of protected objects. At the same time, the module has an angle adjustment function to adjust the size of the defense zone.

[0060] The modules are connected to each other or to the pole body by snap-fit ​​and threaded connections. The module connections use detachable electrical contacts and wiring harnesses for communication and power supply. The transmitting and receiving probes of the warning monitoring module, expulsion monitoring module, and protection monitoring module are fixed with universal joints and can be adjusted according to the actual usage environment such as the size of the warning range.

[0061] The present invention firstly designs the functions of the electronic fence, clarifies the basic functions that the electronic fence should have, and optimizes it structurally, including designing the main structure of the electronic fence, designing functional modules, designing easy-to-replace functions, designing easy-to-carry, and other aspects to deepen the application.

[0062] As attached Figure 1 , Figure 2 The yellow markings shown indicate that the warning rays are emitted by the infrared projector, and the warning area warning line is projected on the ground, and the warning text is projected inside the warning line (the color, brightness, and thickness of the warning line and text can be edited according to the actual situation on site); the warning range can be adjusted by adjusting the up and down angles of the corresponding infrared projector and the height of the pole of the electronic fence, which can quickly expand or reduce the protection area and adjust the buffer distance of each area; at the same time, the area can be prevented from intruders as needed (such as radar waves for personnel, mobile monitoring, infrared detectors for objects, etc.) by selecting the corresponding modules for combination settings. When an animal or object invades the warning area, an audible and visual alarm is issued to prompt the intruder to quickly move away; the warning area refers to the area to prevent accidental entry.

[0063] The red line indicates the coverage of the expulsion zone, and its principle is similar to that of the warning zone. If the intruder continues to invade after the warning zone is triggered, it will enter the expulsion zone. The operation principle of the expulsion zone is similar to that of the warning zone, and other modules can also be selected separately to set up. The expulsion zone can set up high-decibel alarms, mechanical expulsion, strong light expulsion and other measures according to actual conditions to achieve the function of scaring and driving away intruders. The expulsion zone is to prevent small animals and other low-IQ creatures from accidentally entering.

[0064] The black area marks the working area (protection area, isolation area). If the intruder continues to invade after the expulsion area is triggered, it enters the protection area; the protection area can adjust and select the corresponding module according to the actual situation on site or the defense object. The principle is similar to the warning area and the expulsion area. The basic version generally uses infrared counter-shooting and warning fences for physical warnings; if the protection area is breached, the protection linkage is activated (the execution device is started), and the protection linkage conditions are selected according to the actual situation (such as: living things trigger, movement trigger, warning area or expulsion area breach, wind speed, humidity and other natural conditions trigger, etc.), when the triggering conditions are met, the protection action is taken; the output of the protection action result includes but is not limited to disconnecting the test power supply, forcing high-voltage equipment to be powered off and grounded, or notifying staff, etc.; the protection area refers to the emergency situation where the intruder or environmental conditions have reached the point where damage to personnel and equipment is caused, to prevent accidents.

[0065] In some embodiments, if the warning monitoring module and / or the expulsion monitoring module and / or the protection monitoring module is an infrared detector, the height of the infrared detector from the ground and the emission angle of the infrared detector are matched through a genetic algorithm to obtain the optimal infrared detector and the optimal height corresponding to the optimal infrared detector.

[0066] In some embodiments, the specific process of matching the height of the infrared detector from the ground and the emission angle of the infrared detector by using the genetic algorithm is as follows:

[0067] S1. Obtain a set of code strings composed of different emission angles and heights, each of which includes an emission angle and a height, define the code strings as individuals to be solved, and define the code string set as an initial population, let the initial population be the parent population, and let the individuals to be solved in the parent population be the parent individuals. At the same time, set the number of iterations of the genetic algorithm and the number of individuals to be solved in each generation of the population;

[0068] S2. Designing a fitness function based on the emission intensity of the infrared detector received at the farthest distance from the area corresponding to the infrared detector to the rod body, so as to comprehensively evaluate the quality of each individual to be solved;

[0069] S3, performing installation tests on the infrared detectors according to each of the parent individuals of the parent population, and obtaining corresponding test results respectively;

[0070] S4, calculating the fitness value of each of the parent individuals using the fitness function according to each of the test results, and sorting each of the parent individuals in the parent population according to the fitness value;

[0071] S5, based on the fitness value, select the first M parent individuals as offspring individuals, select parent individuals from all parent individuals except the first M parent individuals by roulette wheel to perform crossover and mutation operations to obtain offspring individuals, calculate the fitness values ​​of the offspring individuals after crossover and mutation and sort them, reinsert the offspring individuals into the parent population according to the fitness value, and select a set number of individuals to be solved to form a new parent population;

[0072] S6. Reinstall and test the infrared detector according to the newly generated parent population, and then perform the test to obtain the corresponding test results;

[0073] S7. Repeat S4-S6 until convergence and the optimal individual is found.

[0074] In some embodiments, the fitness function is:

[0075]

[0076] It represents the emission intensity of the infrared detector received by the receiving point whose farthest distance from the qth area to the rod body is l.

[0077] The infrared detector consists of an infrared transmitter and an infrared receiver. The emission angle of the infrared transmitter can range from 15 degrees to 180 degrees. At the same time, the larger the emission angle of the infrared transmitter, the smaller the emission intensity. At the same time, the farther away from the infrared transmitter, the smaller the emission intensity of the infrared transmitter will be.

[0078] Since the emission angle of the infrared transmitter is divergent, when the signal emitted by the infrared transmitter is required to reach a straight line formed by two points at a certain distance from the pole body, the higher the infrared transmitter is from the ground, the smaller the emission angle required by the infrared transmitter. However, this will make the distance between the infrared transmitter and the straight line farther; and the lower the infrared transmitter is from the ground, the closer the distance between the infrared transmitter and the straight line is. However, in this case, an infrared transmitter with a larger emission angle will be selected. Therefore, how to balance the relationship between the emission angle and the height to the ground so that the emission intensity of the infrared transmitter received by the farthest point from the straight line to the pole body is the maximum, so that it can be ensured that the farthest point from the straight line to the pole body can receive the emission signal with the maximum intensity. At the same time, the emission intensity of the infrared transmitter received by each point on the straight line is also the maximum, thereby improving the accuracy of monitoring.

[0079] In this way, the genetic algorithm can be used to obtain the combination of the emission angle of the infrared transmitter and the distance from the infrared transmitter to the ground corresponding to the maximum emission intensity emitted by the infrared transmitter received at the farthest point of the pole in different areas, so that the best infrared detector and the best installation height can be selected to achieve the best effect of the electronic fence.

[0080] In some embodiments, an application of an electronic warning fence railing is also disclosed. The aforementioned electronic warning fence railing is installed outside the area to be protected to form a closed warning area, an expulsion area and a protection area.

[0081] This is a deeper application of fences, including the combined use of multiple fences, and through structural adjustments and the unification of module interfaces and communication protocols, it is easy to replace and combine according to the actual situation; two, three or more fences are physically or signal-loop connected to achieve instant communication and mutual linkage between different fences; it is easy to use and store flexibly, and is more suitable for different working environments and working conditions.

[0082] Here, the settings of warning areas, expulsion areas, and protection areas can be arranged and combined according to actual conditions, and will not be elaborated here.

[0083] As attached Figure 3 As shown, multiple electronic fences can be used to demarcate warning areas according to actual needs on site, and multiple sets of fence devices can be freely combined into isolation areas. Wired communication is used between devices at short distances, and WIFI networking, radio frequency, microwave and other wireless communication methods are used to form linkage at longer distances.

[0084] In high-voltage pressurization test operations, if the electrical connection parts are not in the same working area or the same working plane, fences can be set up in different areas for isolation, and the fence poles in different areas can be linked by a wireless communication network (linked through a control module) to achieve the goal of detecting short circuits, discharges, foreign intrusions and other unexpected situations in other areas. The test voltage can be promptly cut off through the linkage conditions to send out an alarm message, thereby protecting the safety of people and equipment.

[0085] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
