[0034] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0035] This invention provides a complete column anti-collision warning system, referring to... Figure 1 , Figure 1 This is a structural block diagram of the first embodiment of the column anti-collision early warning system of the present invention.

[0036] like Figure 1 As shown, the column anti-collision warning system of the present invention includes: sensor equipment, control equipment and alarm equipment.

[0037] In this embodiment, the sensor device is used to perform distance detection and transmit the generated step signal to the control device.

[0038] It should be noted that the sensor devices described in this embodiment can be laser sensors, infrared sensors, ultrasonic sensors, etc. In the pillar anti-collision warning system, several sensor devices can be installed to acquire distance data. The pillar anti-collision warning system can obtain the unloading distance between the vehicle to be unloaded and the pillar by the sensor devices set on the pillar roof, and then determine whether to issue an anti-collision warning based on the unloading distance.

[0039] It should be explained that the aforementioned sensor equipment is installed with the column as the geometric center and is evenly distributed in a circle on the ceiling.

[0040] For specific layout rules, please refer to Figure 2 , Figure 2 This is a schematic diagram of the sensor arrangement method for the column anti-collision early warning system of the present invention.

[0041] Understandably, in order to prevent situations where the vehicle waiting to be unloaded is already close to the collision post when the driver receives the warning, it is necessary to set a reserved distance to provide advance warning.

[0042] It should be noted that the first reserved distance R1 is the distance between the sensor device and the column, including the second reserved distance R2 and the radius of the distance the unloading vehicle approaches before the sensor device detects the step signal and triggers the warning.

[0043] It should be noted that the step signal is a time-varying voltage and current that changes in the form of a unit step function. When the sensor device detects a vehicle to be unloaded, it will generate a corresponding step signal and send it to the control device.

[0044] It should be understood that when the sensor device detects a vehicle to be unloaded, it will transmit the detected distance data to the control device.

[0045] It is understandable that there is a data processing time between the sensor device detecting the step signal and the issuance of the warning. The first reserved distance R1 includes the distance traveled by the vehicle to be unloaded during the data processing time.

[0046] It should be noted that the second reserved distance R2 is the radius that includes the third reserved distance R3 and the distance the vehicle travels before the unloading vehicle stops approaching the pillar after the warning is issued.

[0047] It is understandable that there is a driver's reaction time and the vehicle's braking time between the alarm device issuing a warning and the driver stopping the vehicle according to the warning. The second reserved distance R2 includes the distance the vehicle travels during the reaction time and braking time.

[0048] It should be noted that the third reserved distance R3 is the radius after the reserved distance between the vehicle and the column and the reduction of the spacing when unloading materials; R4 is the radius of the column.

[0049] It is understandable that when unloading materials from a vehicle, the accumulation of unloaded materials will cause the radius to shrink, and the third reserved distance R3 can increase the distance corresponding to the shrinkage radius.

[0050] It should be noted that several sensor devices are distributed in a circular pattern around the perimeter of the ceiling, and the difference between R1 and R2 is 30 cm. Of course, this difference can be changed according to the actual situation, and this embodiment does not limit it.

[0051] It should be understood that the sensor devices can also be arranged in other ways, such as a rectangular arrangement. In a rectangular arrangement, R1 can be the diagonal length of half a rectangle. Of course, other arrangements can also be used, and this embodiment does not limit this.

[0052] In one implementation, when arranging the sensor devices, if the arrangement method is a circular arrangement, the distance between the sensor devices and the column is a first reserved distance R1.

[0053] It should be noted that the aforementioned control device is an electronic device capable of data processing and signal transmission to realize the anti-collision warning function of the column. It can be an industrial computer, a personal computer, or a server, etc. Appropriate devices can be selected according to the needs in actual applications, and this embodiment does not impose any restrictions on this.

[0054] It is understood that the alarm device mentioned above is a device used to provide alarm prompts in the column anti-collision warning system. The alarm can be triggered by sound and light, or by a single sound. The type of alarm device used can be selected according to the actual application environment, economic conditions, and other conditions. This embodiment does not impose any restrictions on this.

[0055] It should be understood that since the materials being loaded and unloaded may be flammable and explosive, explosion-proof audible and visual alarms can be used in actual use.

[0056] In practice, the sensor device performs distance detection and transmits the resulting step signal to the control device.

[0057] The control device is used to generate early warning determination activation information when the step signal is greater than a preset height, and to generate an early warning command based on the early warning determination activation information.

[0058] It should be noted that the warning determination activation information is a type of information used to indicate the generation of warning commands.

[0059] It should be explained that when the vehicle is unloading materials, false alarms may occur due to the increase in the thickness of the material layer. When the signal value of the step signal is greater than the preset height, it can be regarded as the warning judgment is activated and warning judgment activation information is generated to shield the above-mentioned false alarms.

[0060] It should be explained that the aforementioned preset height is the minimum ground clearance H of the vehicle to be unloaded. min And lowered by 10cm.

[0061] It should be understood that the minimum ground clearance of the vehicle to be unloaded is not fixed and varies for different vehicle types. In practical applications, the minimum ground clearance can be determined based on the vehicle type.

[0062] It should be noted that when the aforementioned control device generates a warning command, it will transmit the warning command to the alarm device so that the alarm device can issue a warning notification based on the warning command.

[0063] In practice, when the step signal is greater than the preset height, the control device generates a warning judgment activation information and generates a warning command based on the warning judgment activation information.

[0064] In one implementation, the column collision warning system proposed in this embodiment also includes an identification device.

[0065] It should be noted that the identification device can acquire image information of the vehicle to be unloaded through the identification apparatus and transmit the image information to the control device. The control device can acquire vehicle information of the vehicle to be unloaded through image recognition technology, and the vehicle information includes the aforementioned minimum ground clearance.

[0066] It should be explained that the aforementioned image recognition technology can obtain vehicle information of vehicles to be unloaded by recognizing the license plate image or the overall image of the vehicle.

[0067] The alarm device is used to issue an early warning prompt based on the early warning command.

[0068] It should be noted that the above warning prompts can be audible and visual prompts or other prompts. Drivers of vehicles waiting to unload can stop their vehicles after receiving the warning prompts to prevent collisions with the pillars.

[0069] In practice, the alarm device issues an early warning notification based on the received warning command.

[0070] In this embodiment, the column anti-collision warning system uses sensor devices to detect distance and transmits the generated step signal to the control device. When the step signal exceeds a preset height, the control device generates warning determination activation information and generates a warning command based on the warning determination activation information. The alarm device can issue a warning prompt based on the warning command. Because the column anti-collision warning system of this invention determines whether to issue a warning command based on the signal monitored by the sensor through the control device, the intelligent column anti-collision warning system reduces the number of manual operation steps and prevents false alarms caused by human factors and increased material layer thickness during material unloading.

[0071] Furthermore, in order to prevent false alarms when people approach, based on the first embodiment of the above-mentioned column collision warning system, a second embodiment of the column collision warning system of the present invention is proposed.

[0072] In this embodiment, the control device is further configured to generate warning determination activation information based on sensor information corresponding to the step signal when the step signal is greater than a preset height;

[0073] The control device is also used to generate a warning command when there is a warning determination start information generated based on the step signals of at least two adjacent sensor devices.

[0074] It should be noted that when the step signal is greater than the preset height, a warning judgment information can be generated based on the sensor information corresponding to the step signal. After the warning judgment information is generated, if the step signal of the adjacent sensor of the sensor corresponding to the step signal also generates a warning judgment information, a warning command is generated.

[0075] In practice, when the step signal is greater than the preset height, the control device generates a warning judgment start information based on the sensor information corresponding to the step signal. When there are warning judgment information generated by the step signals of at least two adjacent sensor devices, a warning command is generated.

[0076] Furthermore, when arranging the sensor devices, if the width of the unloading equipment of the vehicle to be unloaded is 2W, the straight-line distance L between the sensor devices is less than... And it is greater than the preset sensor distance.

[0077] It should be explained that the aforementioned unloading equipment is used to unload materials from vehicles waiting to be unloaded, such as vehicle hoppers. This embodiment and the following embodiments use vehicle hoppers as an example for detailed description.

[0078] It should be noted that the width of the unloading equipment on the vehicle to be unloaded is 2W, the height of the vehicle's hopper from the ground is H, and the straight-line distance between adjacent sensors is L. When arranging the sensors, the following conditions must be met: the straight-line distance between adjacent sensors...

[0079]

[0080] It should be noted that the above preset sensor distance needs to be greater than the shoulder width of an adult (in this embodiment, the shoulder width of an adult is taken as 40 cm). Of course, the preset sensor distance can be set according to the actual application situation, and this embodiment does not limit this.

[0081] Furthermore, in order to prevent the situation where the protection cannot be effectively protected when three adjacent sensors give warnings simultaneously, when arranging the sensor devices, the height H of the perpendicular bisector of the triangle formed by three adjacent sensor devices satisfies H < R2 - R3, where R2 is the second reserved distance and R3 is the third reserved distance.

[0082] It should be understood that three adjacent sensor devices can form a triangle, and the height H of the perpendicular bisector of this triangle needs to satisfy the condition H < R2 - R3, and the specific height can be calculated during implementation.

[0083] It should be noted that another limiting condition for the straight-line distance L between sensor devices can be calculated based on the following formula according to the above perpendicular bisector height:

[0084]

[0085] It can be understood that the specific arrangement method of the sensors can be arranged according to the on-site support conditions, and this embodiment does not limit this.

[0086] In this embodiment, when the step signal is greater than the preset height, the control device of the column anti-collision warning system generates a warning determination start message according to the sensor information corresponding to the step signal; when there is a warning determination start message generated according to the step signals of at least two adjacent sensor devices, a warning instruction is generated, and the sensor devices are arranged according to the arrangement rules, reducing the possibility of misjudgment in the column anti-collision warning system and at the same time reducing the possibility of the vehicle waiting to unload hitting the column.

[0087] In addition, an embodiment of the present invention also proposes a column anti-collision warning method, and the method is applied to the column anti-collision warning system as described above.

[0088] As Figure 3 shown, Figure 3 is a schematic flowchart of the first embodiment of the column anti-collision warning method of the present invention, and the method includes:

[0089] Step S10: The sensor device performs distance detection and transmits the generated step signal to the control device.

The pillar anti-collision warning system can obtain the unloading distance between the vehicle to be unloaded and the pillar by the sensor devices set on the pillar roof, and then determine whether to issue an anti-collision warning based on the unloading distance.

[0091] It should be explained that the aforementioned sensor equipment is installed with the column as the geometric center and is evenly distributed in a circle on the ceiling.

[0092] Understandably, in order to prevent situations where the vehicle waiting to be unloaded is already close to the collision post when the driver receives the warning, it is necessary to set a reserved distance to provide advance warning.

[0093] It should be noted that the first reserved distance R1 is the distance between the sensor device and the column, including the second reserved distance R2 and the radius of the distance the unloading vehicle approaches before the sensor device detects the step signal and triggers the warning.

[0095] It should be understood that when the sensor device detects a vehicle to be unloaded, it will transmit the detected distance data to the control device.

[0096] It is understandable that there is a data processing time between the sensor device detecting the step signal and the issuance of the warning. The first reserved distance R1 includes the distance traveled by the vehicle to be unloaded during the data processing time.

[0097] It should be noted that the second reserved distance R2 is the radius that includes the third reserved distance R3 and the distance the vehicle travels before the unloading vehicle stops approaching the pillar after the warning is issued.

The second reserved distance R2 includes the distance the vehicle travels during the reaction time and braking time.

[0099] It should be noted that the third reserved distance R3 is the radius after the reserved distance between the vehicle and the column and the reduction of the spacing when unloading materials; R4 is the radius of the column.

[0100] It is understandable that when unloading materials from a vehicle, the accumulation of unloaded materials will cause the radius to shrink, and the third reserved distance R3 can increase the distance corresponding to the shrinkage radius.

[0101] It should be noted that several sensor devices are distributed in a circular pattern around the perimeter of the ceiling, and the difference between R1 and R2 is 30 cm. Of course, this difference can be changed according to the actual situation, and this embodiment does not limit it.

[0102] It should be understood that the sensor devices can also be arranged in other ways, such as a rectangular arrangement. In a rectangular arrangement, R1 can be the diagonal length of half a rectangle. Of course, other arrangements can also be used, and this embodiment does not limit this.

[0103] In one implementation, when arranging the sensor devices, if the arrangement method is a circular arrangement, the distance between the sensor devices and the column is a first reserved distance R1.

[0104] It should be noted that the aforementioned control device is an electronic device capable of data processing and signal transmission to realize the anti-collision warning function of the column. It can be an industrial computer, a personal computer, or a server, etc. Appropriate devices can be selected according to the needs in actual applications, and this embodiment does not impose any restrictions on this.

[0105] It is understood that the alarm device mentioned above is a device used to provide alarm prompts in the column anti-collision warning system. The alarm can be triggered by sound and light, or by a single sound. The type of alarm device used can be selected according to the actual application environment, economic conditions, and other conditions. This embodiment does not impose any restrictions on this.

[0109] It should be noted that the warning determination activation information is a type of information used to indicate the generation of warning commands.

[0110] It should be explained that when the vehicle is unloading materials, false alarms may occur due to the increase in the thickness of the material layer. When the signal value of the step signal is greater than the preset height, it can be regarded as the warning judgment is activated and warning judgment activation information is generated to shield the above-mentioned false alarms.

[0111] It should be explained that the aforementioned preset height is the minimum ground clearance H of the vehicle to be unloaded. min And lowered by 10cm.

[0112] It should be understood that the minimum ground clearance of the vehicle to be unloaded is not fixed and varies for different vehicle types. In practical applications, the minimum ground clearance can be determined based on the vehicle type.

[0113] It should be noted that when the aforementioned control device generates a warning command, it will transmit the warning command to the alarm device so that the alarm device can issue a warning notification based on the warning command.

[0114] In practice, when the step signal is greater than the preset height, the control device generates a warning judgment activation information and generates a warning command based on the warning judgment activation information.

[0115] In one implementation, the column collision warning system proposed in this embodiment also includes an identification device.

The control device can acquire vehicle information of the vehicle to be unloaded through image recognition technology, and the vehicle information includes the aforementioned minimum ground clearance.

[0117] It should be explained that the aforementioned image recognition technology can obtain vehicle information of vehicles to be unloaded by recognizing the license plate image or the overall image of the vehicle.

[0118] Step S30: The alarm device issues a warning prompt according to the warning instruction.

[0120] In practice, the alarm device issues an early warning notification based on the received warning command.

[0121] In this embodiment, the column anti-collision warning system uses sensor devices to detect distance and transmits the generated step signal to the control device. When the step signal exceeds a preset height, the control device generates warning determination activation information and generates a warning command based on the warning determination activation information. The alarm device can issue a warning prompt based on the warning command. Because the column anti-collision warning system of this invention determines whether to issue a warning command based on the signal monitored by the sensor through the control device, the intelligent column anti-collision warning system reduces the steps of manual operation and prevents false alarms caused by human factors and increased material layer thickness during material unloading.

[0122] Furthermore, in order to prevent false alarms when people approach, based on the first embodiment of the above-mentioned column anti-collision warning method, a second embodiment of the column anti-collision warning system of the present invention is proposed.

[0123] like Figure 4 As shown, Figure 4 This is a flowchart illustrating the second embodiment of the column anti-collision early warning method of the present invention.
