Description

Technical Field

[0001] The present invention relates to the technical field of logistics automation management, and in particular, to a warehousing safety management system and method. Background Art

[0002] In an automated logistics warehousing system, safe and stable operation is the basis for ensuring its efficient operation. With the rapid development of the logistics industry towards informatization and intelligentization, the application of automated stereoscopic warehouses is becoming increasingly widespread, and their safety management issues have become increasingly important and complex. During the operation of an automated logistics warehousing system, personnel may inadvertently enter the equipment operation area, increasing the risk of personal injury. It may also lead to collisions between personnel and operating equipment, such as AGV equipment (Automated Guided Vehicle) or other logistics equipment.

[0003] In related technologies, the working areas of equipment and personnel are usually divided to ensure safety. However, due to the low awareness of personnel about the working area and the uncertain movement paths of logistics equipment such as AGVs, it is impossible to monitor and warn of personnel dynamics in real time, resulting in low safety management efficiency and the inability to respond promptly to potential safety threats.

[0070] Combined with Figure 1 As shown, the present invention provides a warehousing safety management system, which includes a monitoring unit, an analysis unit, and an alarm unit connected in sequence.

[0071] Specifically, the warehousing safety management system of the present invention consists of three core units: a monitoring unit, an analysis unit, and an alarm unit. These units work together to ensure the safety of the automated logistics warehousing system.

[0072] The monitoring unit is used to obtain the real-time position information of active personnel and the real-time position information of logistics equipment within the monitoring range, and send the real-time position information corresponding to the active personnel and the logistics equipment to the analysis unit respectively.

[0073] Specifically, the monitoring unit collects the position information of active personnel and the real-time position information of logistics equipment (such as AGV) within the monitoring range in real time through sensors, cameras or other positioning technologies installed in the warehouse, and the collected information is then sent to the analysis unit to provide data support for further safety analysis.

[0074] The analysis unit is used to determine the current electronic fence area of the logistics equipment according to the real-time position information of the logistics equipment; and determine whether the active personnel are in a dangerous area according to the position relationship between the real-time position information of the active personnel and the current electronic fence area.

[0075] Specifically, the analysis unit receives data from the monitoring unit, determines its current electronic fence area according to the position information of the logistics equipment, and compares the real-time position of the active personnel with the electronic fence area to judge whether the personnel are approaching or entering a dangerous area. Among them, the electronic fence is a virtual boundary used to identify the safe operation area of the equipment.

[0076] When the active personnel are in the dangerous area, an alarm signal is sent to the alarm unit.

[0077] Specifically, when the analysis unit determines that the active personnel are in a dangerous area, it sends an alarm signal to the alarm unit; the alarm unit sends an alarm message according to the alarm signal through an appropriate alarm method (such as a sound alarm, a light signal, or directly notifying the staff) to alert the relevant personnel to take actions.

[0078] The alarm unit is used to send an alarm message according to the alarm signal.

[0079] Specifically, while giving an alarm, the warehousing safety management system can automatically execute a series of preventive measures. For example, it can adjust the driving path of the AGV to avoid personnel, suspend equipment operations, or guide personnel to leave the dangerous area through the alarm message. Thus, when a potential safety threat occurs, immediate actions can be taken to protect the safety of personnel and equipment.

[0080] The warehousing safety management system of the present invention effectively solves the safety problems in the automated logistics warehousing system by real-time monitoring and analyzing the positional relationship between personnel and equipment; through dynamically determining the electronic fence area and real-time alarming, the system can prevent collisions between personnel and equipment, reduce the risks of work injuries and equipment damage, and thus significantly improve the safety and management efficiency of the warehousing system. Specifically: through the monitoring unit, such as using sensors, cameras or other monitoring devices to track the positions of personnel and equipment, the system can obtain the real-time position information of the active personnel and logistics equipment in real time. The analysis unit dynamically determines the electronic fence area of the logistics equipment according to the position information of the logistics equipment. Among them, it should be noted that: the electronic fence is a virtual boundary used to limit the operation area of the equipment and prevent the logistics equipment from entering crowded or unsafe areas. The analysis unit further analyzes the spatial relationship between the real-time position information of the active personnel and the electronic fence area of the logistics equipment to determine whether the personnel are approaching or entering the dangerous area; and when the analysis unit determines that the active personnel are in the dangerous area, the system immediately sends an alarm signal to the alarm unit, and the alarm unit then sends an alarm message to the relevant personnel through an appropriate method (such as sound, light, vibration, etc.) to remind them to pay attention to safety. Through real-time monitoring and dynamic electronic fence, the system of the present invention can effectively prevent potential collisions between personnel and equipment, thereby improving the safety of the warehousing system; and can quickly identify and respond to potential safety threats, reducing the possibility of accidents. In addition, the automated monitoring and alarming mechanism reduces the need for manual monitoring and improves the efficiency of safety management. Through real-time monitoring and timely alarming, the system helps to reduce accidents caused by personnel straying into the equipment operation area. In summary, the present invention effectively improves the safety during the operation of the warehousing system, reduces the occurrence of safety accidents, and ensures the safety of personnel and equipment through an integrated solution of real-time monitoring, intelligent analysis and timely alarming.

[0081] Optionally, the monitoring unit includes an image acquisition subunit, an image processing subunit, and a positioning subunit that are connected in sequence;

[0082] The image acquisition subunit is configured to acquire image information within the monitoring range;

[0083] The image processing subunit is configured to perform feature extraction based on the image information to determine the active personnel and the logistics equipment in the image information;

[0084] The positioning subunit is configured to perform real-time positioning on the active personnel and the logistics equipment in the image information to obtain real-time position information corresponding to the active personnel and the logistics equipment.

[0085] Specifically, the image acquisition subunit is responsible for capturing image information within the monitoring range. For example, a high-definition camera or other visual sensors are used to record the situation in the warehouse in real time. The image acquisition subunit, such as a camera or a sensor, can capture high-resolution images, providing raw data for subsequent image processing and analysis. It is installed at key positions in the warehouse to cover all possible areas of personnel and equipment activities. The image processing subunit uses image recognition and processing algorithms to analyze the image information provided by the image acquisition subunit, thereby identifying the personnel and logistics equipment in the image, such as AGVs, and determining their identities and states through feature extraction. The positioning subunit calculates and updates the positions of the personnel and logistics equipment in real time based on the information provided by the image processing subunit. Through the collaborative work of the image acquisition subunit, the image processing subunit, and the positioning subunit within the monitoring unit, high-precision monitoring of the activities of personnel and equipment in the automated logistics warehousing environment is achieved. The image acquisition subunit captures real-time images in the warehouse, providing raw visual data for the system; the image processing subunit uses feature extraction technology to identify and distinguish active personnel and logistics equipment, such as AGVs, from these images. Then, the positioning subunit performs real-time positioning on the personnel and equipment based on the processed image information to ensure that the system can accurately grasp their dynamic positions in the warehouse.

[0086] In this optional embodiment, the overall monitoring process not only improves the accuracy and efficiency of safety management, but also enables the system to timely identify and warn of potential safety risks, such as the situation where personnel accidentally enter the equipment operation area or the distance between the equipment and personnel is too close, through real-time data analysis.

[0087] Optionally, the analysis unit is specifically configured to:

[0088] Based on the image information of the monitoring range, determine whether there is a preset fixed electronic fence within the monitoring range;

[0089] If so, determine whether the active personnel are in the dangerous area;

[0090] Among them, when the coordinate point of the active person is within the fixed area of the fixed electronic fence, it is determined that the active person is in the dangerous area;

[0091] When the coordinate point of the active person is outside the fixed area of the fixed electronic fence, it is determined that the active person is not in the dangerous area.

[0092] Specifically, first, the analysis unit checks the image information within the monitoring range to determine whether there is a preset fixed electronic fence. The fixed electronic fence is a virtual boundary set by the system for safety considerations to limit the activity range of personnel and equipment. If there is a preset fixed electronic fence within the monitoring range, the analysis unit will, based on the positional relationship between the real-time coordinate points of the active person and these fixed electronic fences, determine whether the person is in the dangerous area by comparing the coordinate points of the person with the boundaries of the electronic fence area. If the coordinate point of the person falls within the fixed electronic fence area, the system will determine that the person is in the dangerous area; on the contrary, if the coordinate point is outside the electronic fence area, the system will determine that the person is not in the dangerous area.

[0093] In a preferred embodiment of the present invention, probes can be installed around the automated storage and retrieval system (AS / RS) to monitor the perimeter of the AS / RS in real time. Two intrusion boundaries for personnel can be defined through the safety and environmental intelligent system. When a person without a bracelet enters the first safety boundary, the system discovers the intrusion through real-time online algorithms and determines that the person is in a dangerous area. For people without a bracelet, the system uses monitoring probes and real-time online algorithms to detect their intrusion behavior. When these people enter the first safety boundary, the system will sound an alarm through a sound column, and the three-color light will change from green to yellow to warn people approaching the prohibited area. If a person without a bracelet continues to enter the interior of the AS / RS, the system will issue a stronger warning, the three-color light will turn red, and both the warehouse management system and the safety and environmental intelligent system will issue warnings. For people wearing a bracelet, the system uses the UWB positioning system to real-time locate their positions. When the distance between a person wearing a bracelet and an AGV device is too close, the system will issue a collision warning and send a warning message to the person through the bracelet. At the same time, the on-site sound column will also issue a warning of "Beware of collision". The entry behavior of people without a bracelet will trigger data interaction between the warehouse management system and the safety and environmental intelligent system to achieve the transmission of dual-system warning information. The real-time position information of people wearing a bracelet will be used for collision warning and can represent authorized personnel, and will not trigger an intrusion alarm. The system will warn people without a bracelet through visual (change of three-color light) and auditory (alarm sound of the sound column) means to prevent them from entering the dangerous area. In addition to visual and auditory warnings, people wearing a bracelet will also receive direct collision warning information through the bracelet, providing a more personalized and direct warning method. The system will evaluate the risk of people without a bracelet entering the dangerous area and issue corresponding warnings to prevent possible risks such as object strikes and mechanical injuries. The system mainly focuses on the safe distance between people wearing a bracelet and AGV devices to avoid collision risks. Generally speaking, people wearing a bracelet are regarded as authorized users of the system, and their position information is used for more accurate safety warnings such as collision warnings, while people without a bracelet are regarded as potential safety risks, and the system will manage and control their activities through monitoring and warning mechanisms.

[0094] In this alternative embodiment, through an accurate judgment mechanism, the analysis unit can monitor the positional relationship between personnel and equipment in real time, effectively prevent personnel from straying into the equipment operation area, thereby significantly improving the safety of the warehousing system. And based on the real-time image information, the system can quickly respond to changes in personnel positions, issue early warnings in a timely manner, and eliminate potential safety hazards. This not only improves the safety management level of the automated logistics warehousing system, but also reduces work-related injury accidents caused by personnel straying into the equipment operation area through accurate electronic fence monitoring. In addition, the system can provide real-time safety information for management personnel to help them better monitor activities in the warehouse and optimize safety strategies. Through automated monitoring and early warning, the present invention helps to reduce the incidence of safety accidents, improve overall operational efficiency, and at the same time provides a safer working environment for warehouse staff.

[0095] Optionally, the analysis unit is specifically configured to:

[0096] Obtain the electronic fence information corresponding to the equipment type according to the equipment type of the logistics equipment;

[0097] Determine the electronic fence range of the logistics equipment according to the electronic fence information;

[0098] Determine the coordinate point of the logistics equipment according to the real-time position information of the logistics equipment, and use the coordinate point as the center of the electronic fence range to set the current electronic fence area according to the electronic fence range.

[0099] Specifically, the analysis unit obtains the electronic fence information corresponding to the equipment type according to the type of the logistics equipment, such as an automated guided vehicle (AGV) or other automated equipment, where the electronic fence information includes the safe operation area, restricted area or prohibited area of the equipment. The analysis unit uses the real-time position information of the logistics equipment received from the monitoring unit to determine the coordinate point of the equipment; then, with this coordinate point as the center, the current electronic fence area is set according to the electronic fence information, and this electronic fence area is dynamically generated according to the equipment type and preset safety parameters to ensure that the equipment operates within a safe area.

[0100] In this alternative embodiment, by dynamically setting the electronic fence area for each logistics equipment, the analysis unit can ensure that the equipment operates within the preset safe range, enabling the system to adjust the safe area according to different equipment types and actual operating conditions, improving the flexibility and adaptability of the system, and also helping to reduce potential conflicts between equipment and personnel and improve the safety of warehousing operations. In addition, this dynamic adjustment ability also improves the intelligence level of the system, reduces the dependence on manual monitoring, and makes safety management more efficient and automated.

[0101] Optionally, the analysis unit is specifically configured to:

[0102] Generate the coordinate points of the active personnel according to the real-time position information of the active personnel;

[0103] Judge whether the active personnel are in the dangerous area according to the coordinate points;

[0104] Wherein, when the coordinate points are within the current electronic fence area, it is determined that the active personnel are in the dangerous area;

[0105] When the coordinate points are outside the current electronic fence area, it is determined that the active personnel are not in the dangerous area.

[0106] Specifically, the analysis unit receives the real-time position information transmitted by the monitoring unit, generates the coordinate points of the active personnel by converting the position information of the personnel into mathematical coordinates, accurately locates the active personnel, and ensures the accuracy and processability of the position data. Then, the generated coordinate points are compared with the current electronic fence area of the logistics equipment. If the coordinate points fall within the electronic fence area, it indicates that the active personnel are in a potential dangerous area, and the system will determine that they are in the dangerous area. On the contrary, if the coordinate points are outside the electronic fence area, the system will determine that the active personnel are not in the dangerous area.

[0107] In a preferred embodiment of the present invention, the on-site positioning system can be set up to real-time locate the on-site positions of the AGV equipment and the personnel wearing positioning bracelets.

[0108] In this optional embodiment, through the analysis method based on real-time position information, the system can dynamically monitor the safe distance between personnel and equipment, timely identify and warn of possible safety risks. Through accurate coordinate point judgment, the system can effectively distinguish between safe areas and dangerous areas, thereby improving the protection of personnel safety. Through real-time monitoring and accurate judgment, the risk of personnel straying into the equipment operation area is reduced, thereby reducing the incidence of work-related injury accidents.

[0109] Optionally, the analysis unit is specifically configured to:

[0110] After determining that the active personnel are in the dangerous area, determine the shortest straight-line distance between the active personnel and the logistics equipment according to the coordinate points of the active personnel and the coordinate points of the logistics equipment;

[0111] Judge the danger level according to the shortest straight-line distance;

[0112] When the shortest straight-line distance is less than or equal to the first preset distance threshold, it is determined as the first-level danger level, and a first-level alarm signal is sent;

[0113] When the shortest straight-line distance is less than or equal to the second preset distance threshold, it is determined as the secondary danger level, and a secondary warning signal is sent.

[0114] Among them, the first preset distance threshold is greater than the second preset distance threshold, and the urgency of the primary warning signal is lower than that of the secondary warning signal.

[0115] Specifically, when the analysis unit determines that the active personnel are in the danger area, it will calculate the shortest straight-line distance between the coordinate points of the active personnel and the coordinate points of the logistics equipment according to the coordinate points of the active personnel and the logistics equipment, and compare it with the two distance thresholds preset by the system to determine the danger level. If the shortest straight-line distance is less than or equal to the first preset distance threshold, it indicates that the distance between the active personnel and the logistics equipment is very close. The system determines this situation as the primary danger level and sends a primary warning signal. If the shortest straight-line distance is less than or equal to the second preset distance threshold and less than the first preset distance threshold, it indicates that the distance between the active personnel and the logistics equipment is extremely close. The system then determines it as the secondary danger level and sends a secondary warning signal; the urgency of the secondary warning signal is higher than that of the primary warning signal. In this embodiment, the first preset distance threshold is set to be greater than the second preset distance threshold to distinguish different levels of danger situations.

[0116] Exemplarily, in an automated logistics warehousing system, there is a staff member (active personnel) approaching a running automated guided vehicle (AGV, logistics equipment). The monitoring unit obtains the position information of the staff member and the AGV in real time through cameras and sensors installed in the warehouse. The analysis unit receives this information and generates the coordinate points of the staff member and the AGV. For example, the coordinates of the staff member are (X1, Y1), and the coordinates of the AGV are (X2, Y2). The analysis unit calculates the shortest straight-line distance between the staff member and the AGV. If the calculation result shows that the distance between the staff member and the AGV is 2 meters, and the first distance threshold preset by the system is 5 meters, and the second distance threshold is 3 meters; since 2 meters is less than 3 meters, the system determines it as the secondary danger level. That is, it means that the distance between the staff member and the AGV is very close, and there is a potential safety risk. The analysis unit immediately sends a secondary warning signal to the warning unit; the warning unit then issues a warning to the staff member through a sound alarm, a flashing warning light, or warning information on a mobile device. At the same time, the system can also automatically adjust the speed of the AGV or pause its operation to ensure the safety of the staff member. This embodiment successfully avoids a possible collision accident through accurate distance measurement and timely warning. After receiving the warning, the staff member pays attention to observing the surroundings, stops moving forward or avoids the logistics equipment, and the AGV also decelerates at the same time, ensuring the safety of both parties. Through real-time monitoring and rapid response, not only is the staff member protected from harm, but the equipment is also protected from damage, reducing potential property losses and operational interruptions.

[0117] In this alternative embodiment, through such precise distance measurement and risk level judgment, the analysis unit can provide a more detailed safety assessment for the warehousing safety management system. Based on the actual distance between personnel and equipment, the system takes warning measures of different levels. It can not only timely remind the active personnel to pay attention to safety, but also take corresponding preventive measures according to the degree of danger, such as adjusting the operating speed of the equipment or pausing the equipment operation. In addition, such a hierarchical warning system also helps the management personnel quickly identify and respond to emergencies, thereby reducing potential safety hazards and accident losses.

[0118] Optionally, the analysis unit is specifically further configured to:

[0119] When it is determined that the active personnel are in the dangerous area, start timing and monitor in real time the duration of stay of the active personnel in the dangerous area;

[0120] Judge the risk level according to the duration of stay;

[0121] When the duration of stay is greater than or equal to the first preset duration threshold, it is determined as the first-level risk level and a first-level warning signal is sent;

[0122] When the duration of stay is greater than or equal to the second preset duration threshold, it is determined as the second-level risk level and a second-level warning signal is sent;

[0123] Wherein, the first preset duration threshold is less than the second preset duration threshold.

[0124] Specifically, when the analysis unit determines that the active personnel enter or are in the dangerous area, it will start a timer to monitor in real time the staying time of the active personnel in the dangerous area, so as to more accurately evaluate the risk level. Because even if the active personnel enter the dangerous area, if they can leave quickly, the risk will be relatively low. The analysis unit compares the monitored duration of stay with two duration thresholds preset in the system to judge the risk level. If the duration of stay reaches or exceeds the first preset duration threshold, it indicates that the active personnel have stayed in the dangerous area for a long time, and the system determines this situation as the first-level risk level and sends a first-level warning signal. If the duration of stay exceeds the second preset duration threshold but does not reach the first preset duration threshold, the system determines it as the second-level risk level and sends a second-level warning signal. Among them, the first preset duration threshold is set to be less than the second preset duration threshold to distinguish different levels of dangerous situations.

[0125] Exemplarily, in an automated logistics warehousing system, a staff member accidentally enters the working area of an AGV, which is a potentially dangerous area. After the analysis unit discovers through the monitoring system that the staff member has entered the dangerous area, it immediately activates a timer to start monitoring the duration of the staff member's stay in the dangerous area. If the first duration threshold preset by the system is 30 seconds and the second duration threshold is 60 seconds; when the staff member's stay time in the dangerous area reaches 30 seconds, the analysis unit determines it as a first-level danger level and issues a first-level warning signal through the warning unit, such as emitting an emergency alarm sound through the loudspeaker in the warehouse and simultaneously displaying an emergency evacuation instruction on the staff member's mobile device. If the staff member fails to leave in time, when the stay time reaches 60 seconds, the system determines it as a second-level danger level and issues a second-level warning signal. This may include a louder alarm sound and sending an emergency notice to the warehouse management personnel, requesting immediate action. In this embodiment, through the real-time monitoring and timing of the analysis unit, the system can promptly identify and respond to the staff member's stay in the dangerous area, thereby effectively preventing possible safety accidents. The issuance of the first-level warning signal can prompt the staff member to immediately leave the dangerous area, and the second-level warning signal ensures the intervention of the management personnel, increasing the level of safety intervention.

[0126] In this optional embodiment, through this hierarchical warning and response mechanism, the safety of the automated logistics warehousing system can be effectively improved. The staff member avoids potential collisions with the AGV due to the timely warning, and at the same time, it also reduces work interruptions and property losses caused by safety accidents. In addition, this real-time monitoring and warning system also improves the staff member's awareness of compliance with safety regulations because they know that once they enter the dangerous area, the system will immediately respond. And by introducing the stay duration as an additional factor for judging the danger level, the analysis unit can more meticulously evaluate the safety situation, allowing the system to adjust its response according to the actual stay time of the personnel in the dangerous area, thereby more effectively managing and reducing safety risks. The danger level judgment mechanism based on the stay duration in this embodiment can significantly improve the safety management effect of the automated logistics warehousing system. It can not only promptly remind the active personnel to pay attention to safety but also take different levels of early warning measures according to the stay time of the personnel in the dangerous area. In addition, this hierarchical warning system also helps the management personnel quickly identify and respond to emergencies, thereby reducing potential safety risks and accident losses.

[0127] Optionally, the warehousing safety management system is communicatively connected to the logistics warehousing system;

[0128] The warning unit is specifically used for:

[0129] Establishing a connection with the terminal of the active personnel within the monitoring range;

[0130] After receiving the handshake signal sent by the terminal, an alarm message is sent to the terminal and the logistics warehousing system.

[0131] Specifically, as shown in Figure 2 The warehousing safety management system can be an environmental and safety intelligent management system, and the logistics warehousing system can be a warehouse management system. The environmental and safety intelligent management system and the warehouse management system communicate with each other through a wireless network to achieve the interaction and data exchange of early warning information between the two systems. The alarm unit in this embodiment is not only responsible for issuing an alarm when a potential dangerous situation is monitored, but also communicates with the logistics warehousing system. Therefore, when the alarm unit detects that an active person is in a dangerous area, it can timely transmit the alarm information to the logistics warehousing system so as to take corresponding preventive measures. The alarm unit establishes a connection with the terminal device (such as a smart phone, a handheld terminal or other portable devices) carried by the active person through wireless communication technologies such as Wi-Fi, Bluetooth or a dedicated wireless network. For example, when the distance between an AGV device and a person is too close, the system issues an alarm and sends it to the personnel positioning handheld terminal: be careful of collision; synchronize the information and send it to the on-site sound column, be careful of collision; once the terminal device is detected to enter the monitoring range, the alarm unit will attempt to establish a connection with the terminal; when the alarm unit receives the alarm signal sent by the analysis unit, it will send the alarm information to the terminal of the active person through the established connection. At the same time, the alarm unit will also send the alarm information to the logistics warehousing system so that the system can automatically adjust the operation of the logistics equipment, such as pausing the operation of the AGV or changing its path to avoid accidents. The alarm information can also be sent to the on-site sound column to emit an alarm sound, and at the same time, the three-color light changes from green to yellow to warn people to approach the dangerous area.

[0132] In this optional embodiment, through the communication connection with the logistics warehousing system, the alarm unit ensures a rapid response in case of danger. This communication mechanism enables the warehousing safety management system to be synchronized with the logistics operation in real time, ensures that the alarm information can reach the relevant personnel in a timely manner, and at the same time allows the logistics system to automatically respond to potential safety threats, improving the handling efficiency of emergencies and thus reducing the risk of accidents. In addition, this integrated communication mechanism also improves the automation level of warehouse operations, reduces the dependence on manual intervention, and optimizes resource allocation and response time.

[0133] Optionally, the analysis unit is specifically further configured to:

[0134] Identify the image information within the monitoring range and determine whether there are potential safety hazards within the monitoring range;

[0135] If so, send the alarm signal according to the risk level of the potential safety hazard.

[0136] Specifically, the analysis unit uses the image information received from the monitoring unit and, through image recognition algorithms, identifies potential safety hazards within the monitoring range, such as personnel approaching equipment, equipment failures, or other situations that may lead to safety accidents; the analysis unit determines whether there are behaviors violating safety regulations or abnormal equipment states based on the image content. When the analysis unit identifies a safety hazard within the monitoring range, it evaluates the severity of the hazard according to a preset danger level standard. For example, cameras are installed at the AGV charging positions for panoramic shooting, and real-time calculations are performed through the on-site server. When safety accidents such as open flames and smoke occur during the charging process, they are transmitted to the safety and environmental intelligent system, and warnings are broadcast through sound columns and system alarms to avoid losses. According to the evaluated danger level, the analysis unit sends warning signals of corresponding levels to the warning unit to trigger corresponding warning and preventive measures.

[0137] In a preferred embodiment of the present invention, a face access control can also be installed at the entrance and exit of the automated storage and retrieval system in linkage with job applications. During the normal operation of the automated storage and retrieval system, metal contact switches are installed on the physical metal fences at the entrance and exit. When personnel enter the automated storage and retrieval system to carry out equipment maintenance operations without applying for maintenance work, the warehouse management system issues a warning message and it is found that the personnel have entered a dangerous area.

[0138] In this alternative embodiment, through the recognition and evaluation capabilities of the analysis unit, the system is allowed to issue warnings in a timely manner before a danger occurs, providing protection for personnel and equipment and avoiding possible injuries or equipment damage. The warehousing safety management system can more accurately identify and respond to potential safety threats. It also improves the intelligent level of safety management, enabling the system to automatically judge the situation and take appropriate measures, thereby reducing the dependence on manual monitoring and improving the response speed and accuracy.

[0139] In summary, by combining the current electronic fence area of the logistics equipment and the preset fixed electronic fence area to determine whether the moving personnel are in a dangerous area, two warehousing safety management methods can be used for management, and both of the two warehousing safety management methods are applied to the safety and environmental intelligent management system algorithm. One method combines Figure 3 As shown, the warehouse area is monitored by on-site probes. Once a personnel intrusion is detected, subsequent safety mechanisms are triggered. The system has preset electronic fences, and when personnel enter these areas, they are regarded as potential safety risks. When the safety and environmental intelligent management system algorithm detects an intrusion, the information is sent to the safety and environmental intelligent management system algorithm for processing. This algorithm is responsible for analyzing the intrusion situation and determining the corresponding warning level. According to the analysis results, the system may initiate on-site warning measures, including voice warnings through sound columns, red warnings of three-color lights, and sending signals to the warehouse system. The warning information is transmitted to the sports personnel bracelet and the warehouse system operator through the wireless network to ensure that they can receive the warning information in a timely manner and take corresponding actions. Another method combinesFigure 4 As shown in the figure, the UWB positioning system is connected to the personnel positioning device and the AGV positioning device to ensure real-time collection of position data. These data are transmitted to the algorithm of the safety and environmental intelligent management system, which analyzes the position information to determine whether personnel or equipment are approaching or entering a preset dangerous area. If the monitoring system detects a potential safety risk, such as a person entering the working area of an AGV, the intelligent management system will trigger an alarm mechanism. This includes voice alarms from on-site sound columns, red alarms from three-color lights, and sending signals to the warehouse system to take corresponding measures, such as pausing the operation of the AGV. At the same time, the alarm information will also be sent to the bracelets of moving personnel and the operators of the warehouse system to ensure that they can receive the alarm in a timely manner and take necessary actions.

[0140] Combined with Figure 5 As shown in the figure, the present invention provides a warehousing safety management method, which is applied to the warehousing safety management system. The warehousing safety management system includes a monitoring unit, an analysis unit, and an alarm unit connected in sequence;

[0141] The warehousing safety management method includes:

[0142] Obtain the real-time position information of active personnel and the real-time position information of logistics equipment within the monitoring range, and send the real-time position information corresponding to the active personnel and the logistics equipment to the analysis unit respectively;

[0143] The analysis unit determines the current electronic fence area of the logistics equipment according to the logistics equipment;

[0144] According to the position relationship between the real-time position information of the active personnel and the current electronic fence area, determine whether the active personnel are in a dangerous area;

[0145] When the active personnel are in the dangerous area, send an alarm signal to the alarm unit;

[0146] The alarm unit sends alarm information according to the alarm signal.

[0147] The warehousing safety management method of the present invention uses monitoring units, such as sensors, cameras or other monitoring devices, to track the positions of personnel and equipment. The system can obtain the real-time position information of active personnel and logistics equipment in real time. The analysis unit dynamically determines the electronic fence area of the logistics equipment according to the position information of the logistics equipment. Here, it should be noted that: the electronic fence is a virtual boundary used to restrict the operation area of the equipment and prevent the logistics equipment from entering crowded or unsafe areas. The analysis unit further analyzes the spatial relationship between the real-time position information of the active personnel and the electronic fence area of the logistics equipment to determine whether the personnel are approaching or entering a dangerous area; and when the analysis unit determines that the active personnel are in a dangerous area, the system will immediately send an alarm signal to the alarm unit, and the alarm unit will then send an alarm message to the relevant personnel through appropriate means (such as sound, light, vibration, etc.) to remind them to pay attention to safety. Through real-time monitoring and dynamic electronic fences, the system of the present invention can effectively prevent potential collisions between personnel and equipment, thereby improving the safety of the warehousing system; and can quickly identify and respond to potential safety threats, reducing the likelihood of accidents. In addition, the automated monitoring and alarm mechanism reduces the need for manual monitoring and improves the efficiency of safety management. Through real-time monitoring and timely alarms, the system helps to reduce accidents caused by personnel accidentally entering the equipment operation area. In summary, the present invention effectively improves the safety of the warehousing system during operation, reduces the occurrence of safety accidents, and protects the safety of personnel and equipment through an integrated solution of real-time monitoring, intelligent analysis and timely alarms.
