Description

Technical Field

[0001] The present invention relates to the technical field of construction area monitoring, and particularly to an access monitoring and alarm system and method for construction dangerous areas. Background Art

[0002] During the construction of a building, turnstiles are set at the entrances and exits of dangerous construction areas to achieve access monitoring of the dangerous construction areas, prevent personnel or vehicles in non-dangerous construction areas from entering the areas, and reduce the probability of safety hazard accidents.

[0003] Currently, for the operating vehicles in dangerous construction areas, due to the influence of the construction environment, the license plates of the operating vehicles are inevitably covered by substances such as dust, mud, and oil, resulting in the license plate number information being blocked. When the vehicle exits the dangerous construction area, since the turnstile at the entrance and exit cannot accurately read the license plate number information, the vehicle cannot exit quickly, thus causing false alarms in access monitoring. In order to determine whether the vehicle is an operating vehicle, usually in this case, multiple verifications by management personnel are required, which will greatly affect the traffic flow of the road where the turnstile is located and the efficiency of the subsequent freight operations of the operating vehicle; At the same time, if it is subsequently confirmed that the vehicle is an operating vehicle and the turnstile is allowed to release it, then the vehicle may pose a certain potential risk to road traffic safety when driving on the road with the license plate number information blocked; Therefore, how to safely supervise the vehicles in dangerous construction areas, ensure that they can be accurately monitored and identified by the turnstiles at the entrances and exits, and without affecting the traffic flow of the turnstile roads and the freight efficiency of the operating vehicles, implement appropriate planning management for the vehicles in the construction dangerous areas is a problem that needs to be solved currently. Summary of the Invention

[0004] In view of the above-mentioned drawbacks of the prior art, the present invention provides an access monitoring and alarm system and method for construction dangerous areas, which can effectively solve the problem in the prior art that it is impossible to carry out planning management on the vehicles in dangerous construction areas, affecting the accurate identification of the vehicles at the turnstiles at the entrances and exits, resulting in abnormal monitoring and early warning of the turnstiles at the entrances and exits.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: The present invention provides an access monitoring and alarm method for construction dangerous areas, which at least includes: Collect the vehicle identification images of engineering vehicles in the current construction area, and determine whether to generate a second early warning message; Determine the engineering vehicles with abnormalities in the area according to the second early warning message, and determine the operation completion time in combination with the loading volume / unloading volume; Judge whether there are unoperated disposal vacancies initially in the disposal area, where: If there are: Collect the latest arrival time of the construction vehicle in the abnormal situation at the target cargo location, the longest transportation time, and the disposal vacancy to define the driving time within the processing time of the abnormal construction vehicle, and plan the disposal vacancy; If not present: Obtain the remaining processing time of the disposal position, determine a disposal vacancy, define the disposal completion time, and construct the secondary disposal completion time; Determine the time to depart and compare it with the secondary disposal completion time to judge whether to plan a disposal vacancy; Collect the vehicle identification image of the construction vehicle after processing in the abnormal situation, and judge whether to issue an alarm according to the vehicle identification image.

[0006] Furthermore, the method for generating the second warning information is as follows: The collected vehicle identification image is compared with the calibrated vehicle identification image in the engineering database; There is partial matching between the license plate number information in the vehicle identification image and the calibrated vehicle identification image; Identify the remaining unrecognizable actual characters according to the image matching algorithm. If the actual characters are consistent with the calibrated vehicle identification image, generate the second warning information.

[0007] Furthermore, when there is a disposal vacancy, the specific method for planning the disposal vacancy is as follows: Obtain the allowable transportation time A based on the latest time and the current time, compare the allowable transportation time A with the longest transportation time, and judge whether to generate the time difference A; Analyze the time difference A and the processing time, and construct the driving time within the area according to the difference; Obtain the coordinates of each disposal vacancy as the first end coordinate, and the position information at the completion time of the construction vehicle operation in the abnormal situation as the start coordinate; Determine the optimal path to each disposal vacancy with the start coordinate and the first end coordinate; Obtain the driving time of each optimal route, determine the disposal vacancy corresponding to the optimal path based on the driving time within the area, and plan it for the construction vehicle in the abnormal situation.

[0008] Furthermore, when obtaining the driving time of the optimal route, select the disposal vacancy corresponding to the optimal path with a driving time less than the driving time within the area, and plan it for the construction vehicle in the abnormal situation.

[0009] Furthermore, the processing time is obtained according to the ratio of the processing area to the processing speed.

[0010] Furthermore, when there is no disposal vacancy, the specific method for planning the disposal vacancy is as follows: Determine the remaining processing time of each in-use disposal position and clarify the remaining disposal time of the disposal position; The remaining disposal time is combined with the current time to determine the disposal completion time of the disposal position, and the disposal position corresponding to the disposal completion time is converted into a disposal vacancy; Determine a disposal vacancy with the minimum disposal completion time; Determine the estimated processing time of the engineering vehicle inside the anomaly under the disposal vacancy, and add the processing time to the disposal completion time to obtain the secondary disposal completion time; Obtain the latest time for the engineering vehicle inside the anomaly to reach the target cargo position, and subtract the longest transportation time from the latest time to obtain the waiting departure time for the engineering vehicle inside the anomaly to depart from the gate; If the waiting departure time is greater than the secondary disposal completion time, and the engineering vehicle inside the anomaly arrives at the disposal vacancy after the operation completion time under the minimum disposal completion time, allocate the disposal vacancy corresponding to the minimum disposal completion time to the engineering vehicle inside the anomaly.

[0011] Furthermore, if there are multiple planned disposal vacancies, perform the following steps: Calculate the operating safety value of the disposal facilities in the disposal vacancy, specifically: ; Among them, represents the operating value of the automatic sprinkler cleaning system, represents the number of calculation items, represents the water pressure value of the nozzle collected at the th time point, represents the reference water pressure value, represents the water flow rate of the nozzle collected at the th time point, represents the reference water flow rate, represents the vibration value of the nozzle collected at the th time point, represents the reference vibration value corresponding to the nozzle, represents the operating time of the automatic sprinkler cleaning system, 、 、 、 respectively represent the corresponding weight coefficients, represents the collection time, represents the number of collection points; ; Among them, represents the operating value of the brushing device, represents the pressure of the brush on the license plate surface collected at the th time point, represents the reference pressure, represents the rotational speed of the brush collected at the th time point, represents the reference rotational speed, represents the brush vibration value collected at the nth time point, represents the reference vibration value corresponding to the brush, , , , and are the corresponding weight coefficients respectively; Using and to calculate the operation safety value by weighted summation;

[0012] The construction dangerous area access monitoring and alarm system is implemented according to the above-mentioned construction dangerous area access monitoring and alarm method.

[0013] A computer device includes a memory and a processor. The memory stores a computer program, and when the processor executes the computer program, the steps of the method described in any one of the above are implemented.

[0014] A computer-readable storage medium stores a computer program thereon, and when the computer program is executed by a processor, the steps of the method described in any one of the above are implemented.

[0015] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art: By judging the existence of disposal vacancies at the job completion time, a corresponding disposal vacancy planning and allocation scheme is constructed for the abnormal in-plant engineering vehicles, including: Estimating the maximum time loss during the transportation process of the abnormal in-plant engineering vehicles, re-determining the in-plant driving time for the abnormal in-plant engineering vehicles to plan disposal vacancies according to the processing time of the license plate when the abnormal in-plant engineering vehicles arrive at the disposal vacancy, and allocating the disposal vacancies in combination with the in-plant driving time to ensure that the abnormal in-plant engineering vehicles arrive at the target cargo position on time, enabling the license plate to be clearly processed based on the processing time, realizing the operation planning and allocation of the abnormal in-plant engineering vehicles, facilitating the normal identification, release and alarm of the entrance and exit gate machines, and at the same time ensuring the error-free and high-efficiency of the cargo transportation.

[0016] Based on the operation safety value of the disposal facility, the disposable disposal vacancies are determined based on the operation safety value, avoiding potential safety hazards in the disposal facility under the subsequently selected disposal vacancies, which may affect the clear processing of the license plate digital information, so as to ensure the efficient operation of the subsequent abnormal in-plant engineering vehicles. Brief Description of the Drawings

[0017] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0018] Figure 1 It is a schematic diagram of the overall method of the present invention. Specific implementation manners

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] The following further describes the present invention with reference to the embodiments.

[0021] Embodiment 1 (refer to Figure 1 ): The method for monitoring and alarming the access to the construction danger area includes at least: Collect the vehicle identification image (initial) of the engineering vehicle in the current construction area. The vehicle identification image refers to the license plate image, and the vehicle identification image covers the license plate number information (specific characters and character positions). Compare this vehicle identification image with the calibrated vehicle identification images pre-entered in the engineering database to determine whether there is a consistent calibrated vehicle identification image. If they are consistent, no warning information is generated; otherwise, warning information is generated.

[0022] It should be noted that the warning information corresponding to the inconsistency here usually includes two situations: First: The comparison between the collected vehicle identification image and the calibrated vehicle identification images pre-entered in the engineering database shows a direct difference, that is, there is no match between the license plate number information covered in the vehicle identification image and the calibrated vehicle identification image (there is no partial match and one-to-one correspondence in terms of specific characters and character positions). Generate the first warning information. This situation usually indicates that the engineering vehicle corresponding to this vehicle identification image does not belong to the engineering vehicles preset in the current construction area. For example, if a non-area vehicle drives in, there are potential risk hazards; Second: When the collected vehicle identification image is compared with the calibrated vehicle identification image pre-entered in the engineering database and shows a general difference, that is, there is partial matching between the license plate number information covered in the vehicle identification image and the calibrated vehicle identification image, that is, the specific characters and character positions that can be clearly recognized, and the specific characters and character positions have partial correspondence with the calibrated vehicle identification image, including: the quantity of specific characters that can be clearly recognized is greater than the preset threshold. According to the image matching algorithm (such as SIFT, SURF, ORB, character-level convolutional neural network, etc., which compares by identifying unique local features in the image and can handle situations with certain deformations or partial occlusions. The specific details of this case are not elaborated here), identify the vehicle identification image corresponding to the partial match, and determine the actual characters corresponding to the remaining specific characters that cannot be clearly recognized. If the actual characters are consistent with the calibrated vehicle identification image corresponding to the initial vehicle identification image, generate a second warning message. This situation usually occurs during the operation of an engineering vehicle in a construction area, where substances such as dust, mud, and oil on the license plate cover the license plate number information, resulting in partial occlusion of the license plate number information and incomplete recognition.

[0023] If the first warning message is generated, record the engineering vehicle corresponding to the vehicle identification image as an abnormal external engineering vehicle, clarify the location information (i.e., coordinate information) of the abnormal external engineering vehicle, and output the first warning message and the coordinate information to the construction control center for warning, so as to indicate that the construction control center assigns processing personnel to conduct safety verification and control of the abnormal engineering vehicle.

[0024] If the second warning message is generated, obtain the engineering vehicle corresponding to the vehicle identification image under the second warning message and record it as an abnormal internal engineering vehicle, determine the location information of the abnormal internal engineering vehicle, and judge whether the vehicle is in operation. Being in operation usually means that the engineering vehicle is loading or unloading goods in the construction area, such as loading materials such as sand, soil, and steel. If it is in operation, determine the completion time of the operation, and combine the completion time of the operation to plan and allocate disposal vacancies for the abnormal internal engineering vehicle in the disposal area (a disposal position set in the area of the construction area where the license plate number information is clearly disposed, such as a cleaning area or a preset relevant vehicle disposal area. Generally speaking, during the operation of vehicles in the construction area, it is inevitable that substances such as dust, mud, and oil cover the license plate, resulting in partial occlusion of the license plate number information. That is, when the vehicle exits the construction area, the vehicle cannot quickly exit because the gate machine preset at the entrance and exit of the construction area cannot read the license plate number information. Therefore, if the license plate number information of the vehicle cannot be recognized when it reaches the gate machine, and then the license plate number information of the vehicle is clearly disposed, it will inevitably affect the entry and exit efficiency of subsequent vehicles and greatly occupy the project time and road traffic. The method of planning and allocation is as follows: Determine the current loading volume / unloading volume of the construction vehicle within the anomaly ( " / " indicates "or"); Obtain the standard loading volume / standard unloading volume corresponding to the construction vehicle within the anomaly, and calculate the difference between the loading volume / unloading volume and the corresponding standard loading volume / standard unloading volume respectively (it refers to the difference between the loading volume and the standard loading volume, and the same applies to the unloading volume); Determine the current loading rate / unloading rate of the construction vehicle within the anomaly, calculate the loading completion time / unloading completion time according to the ratio of the corresponding difference to the corresponding loading rate / unloading rate, and combine (add) the loading completion time / unloading completion time with the current time to obtain the operation completion time of the construction vehicle within the anomaly; Determine whether there is a disposal vacancy in the (initial) disposal area where no other construction vehicle within the anomaly is being disposed at the operation completion time (the disposal area includes multiple independent disposal vacancies, and each disposal vacancy is equipped with corresponding disposal facilities, including an automatic spray cleaning system, a brushing device, etc. Vehicles in the construction area are often covered with substances such as dust, mud, and oil on the license plate, resulting in the entrance and exit gate machines being unable to read the license plate number information. Due to the large number of construction vehicles in the construction area, multiple independent disposal vacancies are set up to improve the efficiency of simultaneous disposal of multiple vehicles. If all the disposal vacancies are in use, they are recorded as disposal positions), where: If there is a disposal vacancy, obtain the latest time for the construction vehicle within the anomaly to reach the target cargo position (the position where the cargo is transported), and obtain the allowable transportation time A based on the difference between the latest time and the operation completion time. Obtain the historical transportation data and determine the longest transportation time for the construction vehicle within the anomaly to reach the target cargo position from the gate; If the allowable transportation time A is greater than the longest transportation time, obtain the difference between the two to get the time difference A; Determine the expected processing time of the construction vehicle within the anomaly under the disposal vacancy. If the time difference A is greater than the processing time, calculate the difference between the two and record it as the in-area driving time; Obtain the coordinates of each disposal vacancy as the first final coordinate, and the position information of the construction vehicle within the anomaly at the operation completion time as the starting coordinate. Determine the optimal path to each disposal vacancy based on the starting coordinate and the first final coordinate, obtain the driving time of each optimal route, and select the optimal route with a driving time less than the in-area driving time (each optimal route corresponds to a disposal vacancy. Therefore, an appropriate disposal vacancy can be obtained here, and the optimal route is output to the terminal device of the construction vehicle within the anomaly); By limiting the longest transportation time, considering the abnormal impacts on the engineering vehicles within the anomaly during the actual transportation process, estimating the maximum time loss during the transportation process of the engineering vehicles within the anomaly, subsequently redefining the time difference A based on this, and then considering the processing time of the engineering vehicles within the anomaly when arriving at the disposal vacancy to process the license plate, re-determining the drivable time within the area that the engineering vehicles within the anomaly can reach to the disposal vacancy. In this way, when subsequently allocating the corresponding disposal vacancies and the optimal paths, the allocation is combined with the drivable time within the area to ensure that the engineering vehicles within the anomaly arrive at the target cargo position on time, and also enable the license plate to be clearly processed based on the processing time, realizing the operation planning and allocation of the engineering vehicles within the anomaly, and at the same time ensuring the error-free and high-efficiency of the cargo transportation.

[0025] It should be noted that if the driving times are all greater than the drivable time within the area, that is, when no suitable optimal path can be obtained, a warning is sent to the construction control center, and processing personnel are dispatched to handle the abnormal engineering vehicle.

[0026] If there is no disposal vacancy, calculate the remaining processing time of other engineering vehicles within the anomaly under each in-use disposal position (determine the remaining processing area of other engineering vehicles within the anomaly, which is obtained by dividing the remaining processing area by the processing speed. It should be noted that the processing area refers to the area range where the characters on the license plate are covered), and clarify the remaining disposal time of each disposal position; Based on the combination of the remaining disposal time and the current time, determine the disposal completion time of each disposal position, and the disposal position corresponding to the disposal completion time is converted into a disposal vacancy; Determine a disposal vacancy with the minimum disposal completion time; Determine the expected processing time of the engineering vehicle within the anomaly under the disposal vacancy, and add the processing time to the disposal completion time to obtain the secondary disposal completion time; Obtain the latest time for the engineering vehicle within the anomaly to reach the target cargo position, and subtract the longest transportation time from the latest time to obtain the waiting departure time of the engineering vehicle within the anomaly starting from the gate; If the waiting departure time is greater than the secondary disposal completion time (if it is less, the subsequent allocation cannot be executed, and processing personnel are dispatched by the construction control center to handle the abnormal engineering vehicle), and the engineering vehicle within the anomaly can reach the disposal vacancy at the minimum disposal completion time after the operation completion time (that is, the operation completion time is earlier than the minimum disposal completion time, and the difference time between the two is used to determine the optimal path to reach the disposal vacancy based on the starting coordinates and the first end coordinates, and the driving time corresponding to the optimal path does not exceed the difference time), then allocate the disposal vacancy corresponding to the minimum disposal completion time to the engineering vehicle within the anomaly, realizing the operation planning and allocation of the engineering vehicle within the anomaly, the license plate is clearly processed, and at the same time ensuring the error-free and high-efficiency of the cargo transportation.

[0027] Among them, when there are multiple disposal vacancies corresponding to the optimal path determined by the in-area driving time and multiple disposal vacancies corresponding to the same minimum disposal completion time at the same time, the operation safety value of the disposal facilities in the disposal vacancy is calculated synchronously, that is, the operation safety value of the combined automatic sprinkler cleaning system and brushing device set in the normal construction area is determined. The method for determining the operation safety value is as follows: ; Among them, represents the operation value of the automatic sprinkler cleaning system, represents the number of calculation items, represents the nozzle water pressure value collected at the th time point, represents the reference water pressure value, represents the nozzle water flow rate collected at the th time point, represents the reference water flow rate, represents the nozzle vibration value (root mean square value) collected at the , , , represent the corresponding weight coefficients respectively, represents the collection time (that is, by setting a period of collection time, multiple collection points are set within the collection time, and the collection points can be constructed by the hour), represents the number of collection points; ; Among them, represents the operation value of the brushing device, represents the pressure of the brush on the license plate surface collected at the th time point, represents the reference pressure, represents the brush rotation speed collected at the th time point, represents the reference rotation speed, represents the brush vibration value (root mean square value) collected at the , , , are the corresponding weight coefficients respectively; It should be noted that the nozzle water pressure value, nozzle water flow rate, brush vibration value, brush rotation speed, etc. collected above are all data after normalization processing.

[0028] Using and weighted summation to calculate the operation safety value of the disposal facility, and determining the disposal vacancy corresponding to the disposal facility with a small operation safety value as the disposal vacancy to be allocated, so as to avoid potential safety hazards in the use of the disposal facility under the subsequently selected disposal vacancy, which may affect the clear disposal of license plate digital information, and to ensure the efficient operation of the subsequent abnormal in-plant engineering vehicles.

[0029] When determining the optimal path, the optimal path is output to the terminal device configured for the abnormal in-plant engineering vehicle, and at the same time, the second warning information is synchronously output to the terminal device to ensure that the engineering driver is aware of the actual situation of the current abnormal in-plant engineering vehicle, so as to clearly dispose of the license plate digital information of the abnormal in-plant engineering vehicle), and at the same time achieve the conservation of resources in the construction area.

[0030] It is worth noting that through the in-plant driving time and the secondary disposal completion time calculated above, the actual accurate time for the subsequent abnormal in-plant engineering vehicle to complete the disposal under the disposal vacancy can be obtained (which is the secondary disposal completion time, or the sum of the in-plant driving time and the operation completion time). On the one hand, it realizes the planning and allocation of the disposal of abnormal in-plant engineering vehicles. On the other hand, it can, in combination with the actual accurate time, limit the use of the disposal vacancy at the actual accurate time (correspondingly, the vehicle use information corresponding to the actual accurate time can be displayed on the disposal vacancy). Then, before the actual accurate time, other abnormal in-plant engineering vehicles can obtain the information data displayed on the disposal vacancy, which is conducive to other abnormal in-plant engineering vehicles to plan and allocate the use according to the actual accurate time of the disposal vacancy, ensuring the efficient utilization and planning and allocation of the disposal vacancies in the entire construction area (because each abnormal in-plant engineering vehicle can obtain the processing time based on the ratio of the occluded processing area to the historical area processing speed. In this way, for other abnormal in-plant engineering vehicles, they can judge whether to select the corresponding disposal vacancy before the predetermined time based on their own position information, disposal vacancy and processing time).

[0031] Further, the above-mentioned processing time is obtained based on the ratio of the processing area to the processing speed (correspondingly, for dust and oil stains, etc., there are corresponding historical area processing speeds respectively, which will not be elaborated here). Then, the generated image is re-collected for information and output to the corresponding monitoring system under the processing position, so as to predict that after the processing time, the vehicle identification image corresponding to the construction vehicle in the abnormality is re-collected and compared with the calibrated vehicle identification image pre-entered in the engineering database. If they are consistent, the second warning information generated for the construction vehicle in the abnormality is lifted, and the construction vehicle in the abnormality is recorded as a normal construction vehicle and allowed to leave the current processing position. Thus, it can be ensured that when the normal construction vehicle passes through the entrance and exit gates of the construction area, there will be no alarm causing the gates to fail to open normally, improving the passing efficiency of construction vehicles and avoiding traffic congestion corresponding to the gates on the road (generally speaking, there will be a corresponding entrance and exit respectively in the construction area. Therefore, if the vehicle cannot pass normally, the subsequent vehicles will not be able to take over and drive out, resulting in huge congestion. And if the gate is directly opened to allow the vehicle to drive out when it cannot be recognized, it will affect the traffic safety on public roads). Secondly, it can also ensure the normal use of the license plate number information when the normal construction vehicle leaves the construction area, enabling it to drive safely on public roads, avoiding illegal operations and reducing the potential safety hazards of vehicle driving on public roads.

[0032] Therefore, the entrance and exit gates collect and check the vehicle identification image of the construction vehicle in the abnormality after processing. When they are consistent, the gates open and release the vehicle. Otherwise, an alarm is given.

[0033] The construction dangerous area access monitoring and alarm system, applied to the above-mentioned construction dangerous area access monitoring and alarm method, at least includes: The image acquisition and judgment module acquires the vehicle identification image of the construction vehicle in the construction area and judges whether the second warning information is generated; The disposal position planning module determines the construction vehicle in the abnormality according to the second warning information and determines the operation completion time in combination with the loading / unloading volume; Judge whether there is an unoperated disposal position at the initial stage of the disposal area, where: If there is: Acquire the latest time for the construction vehicle in the abnormality to reach the target cargo position, the longest transportation time, and the driving time defined within the processing process time for the disposal of the construction vehicle in the abnormality by the disposal position, and plan the disposal position; If not: Obtain the remaining disposal time of the disposal position and determine a disposal position, define the disposal completion time, and construct the secondary disposal completion time; Determine the time to depart and compare it with the secondary disposal completion time to judge whether to plan the disposal position; Anomaly warning module, which collects the processed vehicle recognition images of engineering vehicles during anomalies and determines whether to issue an alarm based on the vehicle recognition images.
