Description

Technology Field

[0001] The present invention relates to a radar safety barrier with directionality-based zone access control. Specifically, the invention relates to a technology that divides a safe zone and a danger zone by setting the detection area and detection direction of a radar sensor module mounted on the safety barrier, determines whether a moving object detected by the radar sensor module is moving from the danger zone to the safe zone or attempting to enter the danger zone from the safe zone, and performs control to raise the barrier bar of the safety barrier at high speed or lower it at low speed based on the result of determining the directionality of the moving object. Background Technology

[0002] Conventional access control barriers are primarily installed to manage vehicle traffic, and they typically feature a structure that rapidly opens and closes the barrier using loop sensors, infrared sensors, or simple proximity sensors to detect vehicle approach. These conventional barriers are designed for environments controlling relatively simple traffic flow, such as parking lots and building entrances, and do not include separate control logic for ensuring pedestrian safety or guiding evacuation, aside from a re-opening function to prevent vehicle collisions.

[0003] In addition, the opening and closing process of conventional barriers is based on high-speed operation and focuses on facilitating vehicle flow or reopening in the event of a collision, and does not provide a safety-oriented operation process such as low-speed descent to protect pedestrians, securing evacuation delay time, or raising the barrier bar again when additional moving objects are detected during descent.

[0004] Accordingly, the industry is developing various technologies to coordinate the movement of not only vehicles but also pedestrians.

[0005] As an example, Korean registered patent 10-2707675 (traffic barrier for crosswalks capable of effectively controlling the passage of pedestrians and vehicles) discloses a technology installed around a crosswalk to manage the movement of vehicles and pedestrians regardless of whether a traffic light is installed.

[0006] However, the aforementioned prior art only discloses a barrier that can inform drivers of pedestrian crossing times in time even if no traffic lights are installed at the crosswalk formed within the school zone, and induces a vehicle to stop through a barrier bar rotated onto the road. It does not disclose a technology that divides safety zones and danger zones by setting the detection area and detection direction of a radar sensor module mounted on the safety barrier, determines whether a moving object detected by the radar sensor module is moving from the danger zone to the safety zone or intending to enter the danger zone from the safety zone, and performs control to raise the barrier bar of the safety barrier at high speed or lower it at low speed based on the result of determining the direction of the moving object. Therefore, there is a need for a technology that can solve this problem. The problem to be solved

[0007] Accordingly, the present invention is derived to solve the problems of the aforementioned existing technologies, and aims to improve the safety of access control for moving objects (pedestrians and vehicles) between the safety zone and the danger zone by dividing the safety zone and the danger zone through the setting of the detection area and detection direction of a radar sensor module mounted on the safety barrier, determining whether a moving object detected by the radar sensor module is moving from the danger zone to the safety zone or attempting to enter the danger zone from the safety zone, and performing control to raise the barrier bar of the safety barrier at high speed or lower it at low speed based on the result of determining the direction of the moving object. means of solving the problem

[0008] A directional zone access control type radar safety barrier implemented as a computing device comprising one or more processors and one or more memories for storing commands executable by said processors according to an embodiment of the present invention, comprising: a radar sensor module configured to be mounted on the main body of the safety barrier, wherein a detection area and a detection direction are set such that a straight distance and a width can be set, and which performs bidirectional detection targeting the safety zone and the danger zone while the safety zone and the danger zone are partitioned; a movement direction determination unit that determines the movement direction of a moving object based on the approach direction of the moving object when a moving object is detected in one of the safety zone and the danger zone while the function of said radar sensor module is performed; and a barrier bar control unit that, when the confirmed movement direction of the moving object satisfies an escape condition, raises the barrier bar of the safety barrier at high speed, maintains the barrier bar for a preset delay time based on the point in time when the raising of the barrier bar is completed, and, when the preset delay time has elapsed, starts a low-speed lowering process to lower the barrier bar at low speed for a preset lowering time.

[0009] The above radar sensor module is configured to detect moving objects at a preset frequency, and performs real-time detection by demarcating the safety zone and the danger zone through a directivity in which a detection area and a detection direction can be set based on a preset straight-line distance and a preset width, wherein it is configured to detect at least one of a person and a vehicle as the moving object, and preferably has a configuration that can expand the detection area and detection direction by linking with other radar sensor modules.

[0010] Preferably, the above movement direction determination unit comprises: a movement zone verification unit that verifies the zone where the detected movement object is located when a movement object is detected in either the safe zone or the danger zone while the function of the radar sensor module is performed; a first movement direction determination unit that determines the movement direction of the movement object as a first movement direction to enter the danger zone from the safe zone when the location of the movement object detected in real time by the radar sensor module gradually approaches the safety barrier while the location of the movement object is confirmed to be in the safe zone by the performance of the function of the movement zone verification unit; and a second movement direction determination unit that determines the movement direction of the movement object as a second movement direction to enter the safe zone from the danger zone when the location of the movement object detected in real time by the radar sensor module gradually approaches the safety barrier while the location of the movement object is confirmed to be in the danger zone by the performance of the function of the movement zone verification unit.

[0011] Preferably, the above-mentioned blocking bar control unit comprises: an entry blocking control unit that, when the movement direction of a moving body is determined to be a first movement direction by the performance of the function of the movement direction determination unit, maintains the blocking bar of the safety blocking unit to block the moving body from entering a danger zone, and outputs a voice signal prohibiting entry into the danger zone through an output means mounted on the safety blocking unit; and an evacuation opening control unit that, when the movement direction of a moving body is determined to be a second movement direction by the performance of the function of the movement direction determination unit, raises the blocking bar of the safety blocking unit at high speed within a preset raising time to allow the moving body to evacuate from the danger zone to a safe zone.

[0012] The above evacuation opening control unit may include: a blocking bar maintaining unit that maintains the blocking bar in an raised state for a preset delay time when the blocking bar is completed to rise at high speed within the preset rising time; and a lowering process control unit that, when the function of the blocking bar maintaining unit is completed and the preset delay time has elapsed, performs a low-speed lowering process that gradually lowers the blocking bar at a low speed for a preset lowering time, and outputs a voice signal and a warning light announcing the lowering of the blocking bar through the output means at the start of the low-speed lowering process.

[0013] The above evacuation opening control unit can stop the low-speed descent process and raise the blocking bar at high speed within the preset ascent time if the additional moving object detected by the radar sensor module is determined to be a second moving object by the movement direction determination unit while the low-speed descent process is being performed, and then re-perform the low-speed descent process if the additional moving object is not detected.

[0014] It is preferable that the above safety breaker includes: a network-linked control unit linked to a control room, which controls the opening or closing of the blocking bar remotely while monitoring a CCTV mounted on the safety breaker from the control room; and a manual mode control unit that controls the raising or lowering of the blocking bar by a user on-site through the on-site emergency button by changing the mode of the safety breaker from automatic mode to manual control mode when an on-site emergency button located in one area of ​​the safety breaker is operated.

[0015] It is preferable that the above blocking bar implements a low-speed lowering operation through a BLDC motor included in the driving unit, an intermediate reduction gear coupled to the BLDC motor to primarily reduce the rotational force of the BLDC motor, and a final reduction gear coupled to the intermediate reduction gear to further reduce the rotational force of the BLDC motor, which has been primarily reduced by the intermediate reduction gear. Effects of the invention

[0016] Through the direction-based zone access control type radar safety barrier of the present invention, false entry into a danger zone is blocked, and only movement from the danger zone to the safe zone is selectively opened, thereby realizing safer and more precise access control.

[0017] In addition, by applying a stepwise blocking bar profile consisting of high-speed ascent -> delayed maintenance -> low-speed descent -> re-ascent, evacuation safety can be maximized and collision and entrapment accidents that may occur during the descent process can be effectively prevented.

[0024] FIG. 1 is a block diagram illustrating a directional-based zone access control type radar safety barrier according to one embodiment of the present invention.

[0025] Referring to FIG. 1, a directional-based zone access control type radar safety barrier (100) implemented as a computing device comprising one or more processors and one or more memories for storing commands that can be executed by said processors may include a radar sensor module (101), a movement direction determination unit (105), and a barrier bar control unit (107).

[0026] Before describing the above configuration, the safety barrier (100) of the present invention may be installed in various environments where pedestrian or vehicle passage is normally permitted, but access restriction or evacuation guidance may be required in specific situations.

[0027] For example, it can be applied to places where access control is necessary due to changing circumstances, such as areas at risk of flooding, underground spaces, high-traffic pedestrian walkways, and controlled areas where access must be restricted at certain times for safety reasons.

[0028] In this installation environment, the safety barrier (100) can support evacuation by immediately raising the barrier bar when a moving object attempting to move out of the danger zone is detected by demarcating a safe zone and a danger zone through a radar sensor module (101) and determining the direction of movement of the moving object in real time.

[0029] Conversely, the safety barrier (100) can restrict entry into the zone by lowering or maintaining the barrier bar (103) when it is determined that a moving object is attempting to enter the danger zone.

[0030] According to one embodiment, the radar sensor module (101) is configured to be mounted on the main body of the safety breaker (100), and may be configured to perform bidirectional detection targeting the safety zone and the danger zone while the straight distance and width can be set, and the detection area and detection direction are set, thereby partitioning the safety zone and the danger zone.

[0031] According to one embodiment, the radar sensor module (101) is configured to be fixedly installed on one side or the top of the main body of the safety breaker (100), and can set a detection area including a straight distance range (e.g., 0.2m to 6m) and a detection width range (e.g., 0.2m to 3m) that can be set according to the usage environment.

[0032] In addition, the radar sensor module (101) is configured to allow the directional angle or detection direction of the detection signal to be adjusted according to the manager or installation environment, so that a safe zone and a danger zone can be partitioned based on the safety breaker (100) according to the setting of the detection area and detection direction.

[0033] As described above, the radar sensor module (101) can detect the presence of a moving object (person, vehicle, etc.) in real time in an area that includes both zones, based on the partitioned safe zone and danger zone.

[0034] That is, the radar sensor module (101) can perform bidirectional detection of safe zones and danger zones by updating the distance value, detection intensity, location coordinates, etc., with respect to the detected moving object at a regular interval (e.g., in milliseconds).

[0035] In summary, the radar sensor module (101) is configured to detect moving objects at a preset frequency (e.g., 60 GHz), and is configured to perform real-time detection by partitioning the safe zone and the danger zone through a directional orientation in which a detection area and a detection direction can be set based on a preset straight distance and a preset width, and is configured to detect at least one of a person and a vehicle as the moving object, and may be configured to expand the detection area and detection direction by linking with other radar sensor modules.

[0036] According to one embodiment, the movement direction determination unit (105) can determine the movement direction of a moving object based on the approach direction of the moving object when a moving object is detected in one of the safe zone and the danger zone while the function of the radar sensor module (101) is being performed.

[0037] According to one embodiment, when a moving body is detected in a detection area corresponding to a safe zone or a danger zone by the radar sensor module (101), the moving direction determination unit (105) can preferentially identify the zone (safe zone or danger zone) where the moving body was detected from the detection result.

[0038] At this time, the movement direction determination unit (105) can determine whether the moving object is gradually approaching the safety barrier (100) based on the detection distance signal to the moving object or the change in detection intensity information periodically input from the radar sensor module (101).

[0039] According to one embodiment, the movement direction determination unit (105) can determine that the moving body intends to move from the safe zone toward the danger zone (first movement direction) when it is confirmed that the detection distance to the moving body is decreasing while the moving body is first detected in the detection area toward the safe zone.

[0040] Conversely, the movement direction determination unit (105) can determine that the moving body intends to move from the danger zone toward the safe zone (second movement direction) when it is confirmed that the detection distance to the moving body decreases while the moving body is first detected in the danger zone side detection area.

[0041] According to one embodiment, the blocking bar control unit (107) can raise the blocking bar (103) of the safety blocker at high speed when the movement direction of the confirmed moving body satisfies the escape condition, and then maintain the blocking bar (103) for a preset delay time based on the point in time when the raising of the blocking bar (103) is completed, and when the preset delay time has elapsed, start a low-speed lowering process and lower the blocking bar (103) at low speed for a preset lowering time.

[0042] According to one embodiment, if the blocking bar control unit (107) determines from the movement direction determination unit (105) that the moving body intends to move from a danger zone to a safe zone, it can confirm that the moving body satisfies an escape condition (e.g., a condition of moving from a danger zone to a safe zone).

[0043] In relation to the above, the blocking bar control unit (107) can control the blocking bar (103) to be raised at a high speed first so that the moving body can safely pass through the safety blocker when the escape condition is satisfied.

[0044] At this time, the reason the blocking bar control unit (107) raises the blocking bar (103) at high speed within a preset raising time is that immediate opening of the blocking bar (103) is required the moment the moving body escapes from the danger zone.

[0045] In relation to the above, the preset rising time refers to the target time required for the barrier bar to reach the fully raised position from its initial lowered position, and the time includes a time range set for the barrier bar to rise at high speed to rapidly support the evacuation of the moving object, and can be adjusted by the manager.

[0046] According to one embodiment, the blocking bar control unit (107) can check whether the blocking bar (103) has reached a height-completed position by monitoring the operating state of a drive unit mechanically connected to the blocking bar (103), and if it is confirmed that the blocking bar (103) has been fully raised, the blocking bar (103) can be controlled to be maintained in a height-completed state for a preset delay time so that a moving body can pass through the safety blocker (100).

[0047] In relation to the above, the pre-set delay time refers to a pre-set time interval to maintain the blocking bar (103) in a raised state so that a moving object evacuating can sufficiently pass through the safe zone after the blocking bar (103) has been raised.

[0048] At this time, the above-mentioned pre-set delay time may be a value that is pre-set or adjustable by an administrator, taking into account the passing speed of the evacuation target, characteristics of the installation environment, or safety standards, and after the above-mentioned delay time has elapsed, the low-speed lowering process of the blocking bar (103) may be initiated.

[0049] According to one embodiment, the blocking bar control unit (107) can start a slow lowering process to gradually lower the blocking bar (103) after the delay time has elapsed.

[0050] In relation to the above, the low-speed descent process may be performed by lowering the blocking bar (103) at a constant speed for a preset descent time. This low-speed descent control is intended to reduce the risk of collision with pedestrians or moving objects that may occur during the descent process, and the descent may be temporarily suspended if necessary, depending on the movement of additionally detected moving objects.

[0051] FIG. 2 is a block diagram illustrating the movement direction determination unit of a direction-based zone access control type radar safety barrier according to one embodiment of the present invention.

[0052] Referring to FIG. 2, a directional-based zone access control type radar safety barrier (e.g., the directional-based zone access control type radar safety barrier (100) of FIG. 1) implemented as a computing device comprising one or more processors and one or more memories for storing instructions that can be executed by said processors may include a movement direction determination unit (200) (e.g., the movement direction determination unit (105) of FIG. 1).

[0053] According to one embodiment, the movement direction determination unit (200) can determine the movement direction of a moving object based on the approach direction of the moving object when a moving object is detected in one of the safe zone and the danger zone while the function of the radar sensor module (207) (e.g., radar sensor module (105) of FIG. 1) is being performed.

[0054] According to one embodiment, the movement direction determination unit (200) may include a movement zone verification unit (201), a first movement direction determination unit (203), and a second movement direction determination unit (205) as detailed configurations for performing the above-described function.

[0055] According to one embodiment, the moving object zone verification unit (201) can verify the zone where the detected moving object is located when a moving object is detected in one of the safe zone and the danger zone while the function of the radar sensor module (207) is performed.

[0056] According to one embodiment, the moving body zone verification unit (201) can primarily identify whether the location where a moving body is detected is a detection area corresponding to the safe zone or a detection area corresponding to the danger zone, based on a detection signal periodically provided from the radar sensor module (207).

[0057] In relation to the above, the radar sensor module (207) can detect detection zones corresponding to the safe zone and the danger zone, respectively, in real time based on the set detection distance range and detection direction.

[0058] Accordingly, the mobile body zone verification unit (201) can determine which zone the mobile body is currently located in by comparing the location value of the detected mobile body (e.g., detection distance value, detection direction angle value) with the detection zone.

[0059] For example, the above-mentioned moving object zone verification unit (201) can determine that the moving object is located in a safe zone if it is confirmed that the straight-line distance of the moving object detected by the radar sensor module (207) is included within the range set in the safe zone area.

[0060] Conversely, the above-mentioned moving object zone verification unit (201) can determine that the moving object is located in a danger zone if it is confirmed that the detection distance of the moving object falls within a range corresponding to a danger zone area.

[0061] According to one embodiment, the first movement direction determination unit (203) can determine the movement direction of the moving body as a first movement direction intended to enter the danger zone from the safety zone when the position of the moving body detected in real time by the radar sensor module is gradually approaching the safety barrier while the position of the moving body is confirmed to be in the safety zone by the performance of the function of the moving body zone confirmation unit (201).

[0062] According to one embodiment, the first movement direction determination unit (203) can confirm that the detection distance to the moving object gradually decreases over time through the detection distance value periodically provided by the radar sensor module (207), while the moving object zone confirmation unit (201) confirms that the moving object is first detected in the detection area on the safe zone side.

[0063] Accordingly, the first movement direction determination unit (203) can determine that the moving body is moving from the safe zone toward the danger zone.

[0064] Here, the phrase "gradually approaching" means that the position of the moving object is moving toward the safety breaker side based on continuous distance values ​​(e.g., decrease in distance, increase in signal strength, etc.) at which the moving object is detected.

[0065] That is, the first movement direction determination unit (203) can determine that the moving body is approaching the danger zone direction if the detection distance continuously decreases over time after the moving body is detected in the detection area corresponding to the safe zone.

[0066] Accordingly, the first movement direction determination unit (203) can determine the movement direction of the moving body as the first movement direction intended to enter the danger zone from the safe zone.

[0067] According to one embodiment, the second movement direction determination unit (205) can determine the movement direction of the moving body as a second movement direction intended to enter the safety zone from the danger zone when the position of the moving body detected in real time by the radar sensor module is gradually approaching the safety barrier while the position of the moving body is confirmed to be in the danger zone by the function of the moving body zone confirmation unit (201).

[0068] According to one embodiment, the second movement direction determination unit (205) can determine that the moving body is moving from the danger zone to the safe zone when, in a state where the moving body is first detected in the danger zone side detection area by the moving body zone confirmation unit (201), the detection distance to the moving body is gradually decreasing through the detection distance value provided by the radar sensor module (207).

[0069] That is, the second movement direction determination unit (205) can determine that if the distance value to the moving body in subsequent detections continuously decreases after the moving body is first detected in the danger zone area, it corresponds to a second movement direction in which the moving body moves out of the danger zone and into a safe zone.

[0070] FIG. 3 is a block diagram illustrating a blocking bar control unit of a directional-based zone access control type radar safety barrier according to one embodiment of the present invention.

[0071] Referring to FIG. 3, a directional-based zone access control type radar safety barrier (e.g., the directional-based zone access control type radar safety barrier (100) of FIG. 1) implemented as a computing device comprising one or more processors and one or more memories for storing instructions that can be executed by said processors may include a barrier bar control unit (300) (e.g., the barrier bar control unit (107) of FIG. 1).

[0072] According to one embodiment, the blocking bar control unit (300) can raise the blocking bar of the safety blocker at high speed when the movement direction of the confirmed moving body satisfies the escape condition, and then maintain the blocking bar for a preset delay time based on the point in time when the raising of the blocking bar is completed, and when the preset delay time has elapsed, start a low-speed lowering process and lower the blocking bar at low speed for a preset lowering time.

[0073] According to one embodiment, the blocking bar control unit (300) may include an entry blocking control unit (301) and an evacuation opening control unit (303) as detailed configurations for performing the above-described function.

[0074] According to one embodiment, when the movement direction of a moving body is determined to be a first movement direction by the function of a movement direction determination unit (e.g., movement direction determination unit (105) of FIG. 1), the entry blocking control unit (301) maintains the blocking bar of the safety blocker to block the moving body from entering the danger zone from the safety zone, and can output a voice signal prohibiting entry into the danger zone through an output means mounted on the safety blocker.

[0075] According to one embodiment, when the entry blocking control unit (301) confirms that the movement direction of the moving body is moving from the safe zone to the danger zone direction by performing the function of the movement direction determination unit, it can control the blocking bar to maintain a lowered state or lower a blocking bar in a raised state so that the moving body cannot enter the danger zone.

[0076] In addition, the entry blocking control unit (301) may drive an output means (e.g., speaker, warning sound generator, warning light, etc.) provided in the safety blocker to clearly convey to the vehicle and surrounding users that the vehicle is approaching a danger zone, and output a voice signal or warning sound that indicates "prohibition of entry into danger zone."

[0077] According to one embodiment, the entry blocking control unit (301) can output the warning output repeatedly or continuously while the moving body is continuously detected within the danger zone side detection area, and can effectively prevent the moving body from intruding into the danger zone by controlling the position of the blocking bar to be maintained even during the warning output.

[0078] According to one embodiment, when the movement direction of the moving body is determined to be a second movement direction by the function of the movement direction determination unit, the evacuation opening control unit (303) can raise the blocking bar of the safety breaker at high speed within a preset raising time so that the moving body can evacuate from the danger zone to the safety zone.

[0079] According to one embodiment, when the evacuation opening control unit (303) confirms a second movement direction in which a moving body is moving from a danger zone toward a safe zone by performing the function of a movement direction determination unit, it can control the blocking bar to be raised at high speed within a preset raising time so that the moving body can evacuate quickly.

[0080] In relation to the above, the evacuation opening control unit (303) can monitor the operating status of the drive unit (e.g., BLDC motor, intermediate reducer, final reducer and reduction gear set) to check whether the blocking bar has reached a fully raised position (evacuation possible position) after starting the upward drive.

[0081] According to one embodiment, the high-speed upward control of the barrier bar is intended to minimize the time a moving object remains in a danger zone, and in particular, when a moving object is approaching a safety barrier from a radar sensor module, the control method may be one that ensures an immediate open state so that the barrier bar does not become an obstacle.

[0082] FIG. 4 is a block diagram illustrating the evacuation opening control unit of a directional-based zone access control type radar safety barrier according to one embodiment of the present invention.

[0083] Referring to FIG. 4, a directional-based zone access control type radar safety breaker (e.g., the directional-based zone access control type radar safety breaker (100) of FIG. 1) implemented as a computing device comprising one or more processors and one or more memories for storing commands that can be executed by said processors may include an evacuation opening control unit (400) (e.g., the evacuation opening control unit (303) of FIG. 3).

[0084] According to one embodiment, when the movement direction of a moving body is determined to be a second movement direction by the function of the movement direction determination unit (e.g., movement direction determination unit (103) of FIG. 1) of the evacuation opening control unit (400), the blocking bar of the safety breaker can be raised at high speed within a preset rising time so that the moving body can evacuate from the danger zone to the safety zone.

[0085] According to one embodiment, the evacuation opening control unit (400) may include a blocking bar holding unit (401) and a lowering process control unit (403) as detailed configurations for performing the above-described function.

[0086] According to one embodiment, the blocking bar holding member (401) can maintain the blocking bar in a raised state for a predetermined delay time when the blocking bar is completed to rise rapidly within the predetermined rising time.

[0087] According to one embodiment, the blocking bar holding part (401) can check whether the blocking bar has reached a fully raised position through an operation signal of the driving part or a position sensor, etc., after the blocking bar has been raised at high speed within a preset rising time by the evacuation opening control part (303).

[0088] According to one embodiment, the blocking bar maintaining unit (401) can control the blocking bar to be maintained in a raised state for a preset delay time so that when it is determined that the blocking bar has been fully raised, the moving body can move completely to a safe zone and complete evacuation.

[0089] According to one embodiment, the blocking bar maintaining unit (401) can maintain the raised state of the blocking bar by stably maintaining the output of the driving unit so that the blocking bar does not unnecessarily descend during the preset delay time, or by blocking the control signal so that the descending operation is not initiated.

[0090] According to one embodiment, the lowering process control unit (403) performs a low-speed lowering process for gradually lowering the blocking bar during a low-speed lowering time when the function of the blocking bar holding unit (401) is completed and the preset delay time has elapsed, and can output a voice signal and a warning light announcing the lowering of the blocking bar through the output means at the start of the low-speed lowering process.

[0091] According to one embodiment, the lowering process control unit (403) can start a low-speed lowering process to lower the blocking bar based on the point in time when the preset delay time has elapsed, while the blocking bar is maintained in a raised state for a preset delay time by the blocking bar holding unit (401).

[0092] In relation to the above, the low-speed descent process can be controlled to gradually lower the blocking bar within a constant speed range during a preset descent time to prevent a situation where the blocking bar suddenly descends and collides with a moving object.

[0093] At this time, the above-mentioned pre-set descent time is a target time for limiting the descent speed of the blocking bar, and may be a value pre-defined by the administrator settings.

[0094] According to one embodiment, the lowering process control unit (403) can output a voice signal and a warning light to notify surrounding users that the blocking bar is lowering through an output means (e.g., speaker, warning sound generator, warning light, etc.) provided in the safety blocker at the time when the low-speed lowering process starts.

[0095] According to one embodiment, the lowering process control unit (403) can be performed continuously or at a regular interval during the lowering section of the blocking bar when a warning is output, and can prevent collision and contact accidents from occurring because the moving body does not recognize the lowering operation of the blocking bar.

[0096] According to one embodiment, if the movement direction of an additional moving body detected by the radar sensor module is determined to be a second movement direction by the movement direction determination unit while the low-speed descent process is being performed, the low-speed descent process may be stopped and the blocking bar raised at high speed within the preset rising time, and if the additional moving body is not detected, the low-speed descent process may be performed again.

[0097] According to one embodiment, the evacuation opening control unit (400) can receive a determination signal from the movement direction determination unit that a moving body additionally detected is moving in a second movement direction, i.e., from a danger zone to a safe zone, while the blocking bar is being lowered at a low speed for a preset lowering time by the lowering process control unit (403).

[0098] Accordingly, the above evacuation opening control unit (400) can immediately stop the low-speed descent process currently being performed.

[0099] According to one embodiment, the evacuation opening control unit (400) can control the drive unit to raise the blocking bar again at high speed within a preset rising time so that the moving body can quickly evacuate to a safe zone while the low-speed descent process is stopped.

[0100] According to one embodiment, the driving unit is configured to be mechanically connected to the blocking bar, and can implement a low-speed lowering operation of the blocking bar through a BLDC motor that provides rotational force for raising and lowering the blocking bar, an intermediate reduction gear coupled to the BLDC motor that primarily reduces the rotational force of the BLDC motor, and a final reduction gear coupled to the intermediate reduction gear that further reduces the rotational force of the BLDC motor whose rotational force has been primarily reduced by the intermediate reduction gear.

[0101] According to one embodiment, the driving unit may include a BLDC motor (e.g., a brushless DC motor) that generates rotational force to perform the raising and lowering movements of the blocking bar, configured to be mechanically coupled to one end of the blocking bar or a connecting link structure.

[0102] In relation to the above, since the BLDC motor may have a high rotational speed and limited torque for directly driving the blocking bar, it may be coupled with a set of reduction gears in multiple stages to convert the rotational force of the BLDC motor into an appropriate speed and torque.

[0103] More specifically, the above drive unit may include an intermediate reduction gear (1st stage reduction gear) coupled to the output shaft of the BLDC motor to primarily reduce the rotational force of the BLDC motor.

[0104] In relation to the above, the intermediate reduction gear can operate to reduce the rotation of a high-speed rotating motor to secure a basic torque for driving a blocking bar.

[0105] In addition, the above drive unit may further include a final reduction gear coupled to the output shaft of the intermediate reduction gear.

[0106] In relation to the above, the final reduction gear acts as a two-stage reduction gear that further reduces the rotational force of the BLDC motor, which has been reduced by the first reduction gear, thereby stably controlling the descent speed to prevent the blocking bar from descending excessively quickly during the low-speed descent process.

[0107] As the above intermediate reduction gear and the above final reduction gear are configured with a 2-stage or 3-stage reduction structure, the blocking bar can rise quickly by converting the rotational force of the BLDC motor into a relatively large torque when high-speed rising is required, and conversely, when low-speed falling is required, it can descend smoothly and safely at a low speed with the rotational force sufficiently reduced through a reduction stage.

[0108] Accordingly, the evacuation opening control unit (400) can control the driving unit so that if detection of additional moving bodies is no longer performed or if it is confirmed that a moving body has moved out of the detection range in a continuous detection signal, the stopped low-speed descent process can be restarted.

[0109] That is, the above evacuation opening control unit (400) automatically performs a state transition of slow descent → re-ascent → passage of moving body → resumption of descent according to the moving body detection condition, thereby preventing the risk of collision of moving bodies while the blocking bar is descending and repeatedly assisting in the evacuation of moving bodies attempting to escape from the danger zone.

[0110] FIG. 5 is another block diagram illustrating a directional-based zone access control type radar safety barrier according to one embodiment of the present invention.

[0111] Referring to FIG. 5, a directional-based zone access control type radar safety barrier (e.g., the directional-based zone access control type radar safety barrier (100) of FIG. 1) implemented as a computing device comprising one or more processors and one or more memories for storing instructions that can be executed by said processors may include a network linkage control unit (501) and a manual mode control unit (503).

[0112] According to one embodiment, the network linkage control unit (501) is linked with a management room, and can control the opening or closing of the blocking bar remotely while monitoring the CCTV mounted on the safety blocker from the management room.

[0113] According to one embodiment, the network linkage control unit (501) is configured to be connected to a management room, for example, via a TCP-IP-based wired or wireless network, and can transmit a video stream so that video information of a CCTV camera equipped in the safety breaker can be checked in real time at a monitoring device installed in the management room.

[0114] In relation to the above, the manager of the control room can determine the movement of pedestrians or vehicles at the site, signs of danger, or emergency situations based on the CCTV footage, and can transmit a control command to the network linkage control unit (501) to remotely raise or lower the barrier bar according to the result of the determination.

[0115] Accordingly, the network linkage control unit (501) can transmit a remote control command received from the control room to the blocking bar control unit, thereby controlling the operation of the drive unit so that the blocking bar can be immediately opened (raised) or blocked (lowered) according to remote operation.

[0116] In addition, the network linkage control unit (501) can continuously monitor the network status and, if an abnormal state such as data transmission delay or network disconnection occurs, set the local automatic control mode to be executed first, and automatically transition the state so that remote control input can be received again when the network is normalized.

[0117] According to one embodiment, the manual mode control unit (503) can control a user in the field to raise or lower the blocking bar through the field emergency button by changing the mode of the safety breaker from automatic mode to manual control mode when the field emergency button placed in one area of ​​the safety breaker is operated.

[0118] According to one embodiment, when the manual mode control unit (503) receives an operation signal from a field emergency button installed on the main body of the safety circuit breaker for field emergency response, it can immediately switch the operation mode to manual control mode even if the safety circuit breaker is currently operating in automatic mode.

[0119] In relation to the above, the manual control mode is a mode in which a detection signal received from a radar sensor module or an automatic control signal provided from a network linkage control unit is temporarily disabled or its priority is lowered, and the manual control signal is transmitted to the blocking bar control unit so that a user at the site can directly control the operation of the blocking bar.

[0120] According to one embodiment, the manual mode control unit (503) converts the operation input of the button (e.g., holding the button, repeated pressing) into a command to raise or lower the blocking bar when the field emergency button is pressed, and transmits this to the blocking bar control unit, thereby allowing the blocking bar control unit to control the drive unit (motor and reduction gear set) based on the received command so that the user can immediately raise or lower the blocking bar when necessary.

[0121] In addition, the manual mode control unit (503) can return the mode of the safety circuit breaker to automatic mode when the operation of the field emergency button ends or when the manual mode release condition is satisfied according to the settings of the control room.

[0122] That is, the manual mode control unit (503) can enable a field user to directly control the safety circuit breaker even in situations where immediate opening and closing operations are required at the site, such as sensor malfunctions or network errors, through the manual mode control function as described above.
