[0039] Figure 2 The figure is a schematic flow chart of a method for safety management of a scrap steel yard in one embodiment of the present invention. DETAILED DESCRIPTION

[0040] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0041] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0042] See also Figure 1 The present invention provides a scrap steel yard safety management system, including a server and a terminal.

[0043] In one embodiment, the server side includes: a permission management module, a device management module, a personnel management module and a job management module.

[0044] In one embodiment, the authority management module includes: an access control authority management unit, an area authority management unit, and an equipment use authority management unit. The scrap steel yard can be pre-divided into a plurality of authority areas with different access rights through the authority management module combined with the map of the scrap steel yard. The verification method is not configured for each authority area. Exemplarily, an access control authority management unit can be set for the authority verification at the entrance of the scrap steel yard, and the access control authority management unit performs identity authentication by obtaining the facial image of the person at the entrance collected by the camera. When a vehicle enters the entrance, the camera can also collect information such as the license plate image of the vehicle, and the recognized license plate information is compared with the stored authorized vehicle information to determine whether the vehicle at the entrance is an operating vehicle. If it is an operating vehicle, the verification is passed; if there is no data matching the collected license plate information, the corresponding vehicle is determined to be an external vehicle, and the license plate information and driver-related information are fed back to the authorized manager, and the manager temporarily authorizes the external vehicle based on the feedback information. Similarly, in the case where the personnel verification fails, the basic information of the corresponding personnel can also be collected through the authority management module to apply for temporary authorization. A regional authority management unit can be set for the authority verification of the authority area in the scrap steel yard. The regional authority management unit performs authority verification by obtaining the image information of the corresponding area collected by the camera in the scrap steel yard. For example, the facial image of the operator in the scrap steel yard or the license plate information of the operating equipment such as a truck, a steel grabber, etc. can be collected for identification. The operator and operating equipment information can be associated with the authority area in advance. When it is determined by image recognition that the corresponding operator or operating equipment in the current detection area does not have the authority to enter the current detection area, a safety warning is activated for timely intervention and management. The corresponding use authority and / or the specified equipment verification method can also be assigned to the operating equipment entering the scrap steel yard through the equipment use authority management unit. The verification methods include face recognition, license plate recognition, QR code verification, password verification, etc. The operating equipment may include a steel grabber, a vehicle responsible for loading and unloading scrap steel, etc.

[0045] In one embodiment, the equipment management module includes: an outdoor positioning unit, which is used to obtain the location information of the operating equipment located outdoors through GPS positioning, and update it to the scrap steel material site map; an indoor positioning unit, which is used to obtain the location information of the corresponding operating equipment located indoors according to the relative position of the positioning tag pre-installed on the operating equipment and the indoor signal station, and update it to the scrap steel material site map; a sensor unit, which is installed on the corresponding operating equipment, and is used to obtain the equipment status of the corresponding operating equipment, wherein the equipment status includes: equipment posture and whether it is idle. The equipment identification management module also includes a foreign vehicle detection unit, which is used to call the image acquisition device in the scrap steel yard to obtain the license plate image of the foreign vehicle, and monitor the movement trajectory of the foreign vehicle with the corresponding license plate in the scrap steel yard according to the position of the image acquisition device. If the foreign vehicle enters an area without access rights, a safety warning is activated. Specifically, multiple signal stations can be set in the scrap steel yard, and positioning tags can be installed on each operating equipment, and the current location and status of the equipment can be displayed on the ArcGIS map. GPS positioning is used outdoors, and UWB positioning is used indoors, and a movement trajectory is formed. The camera monitors incoming vehicles by recognizing their license plates and their locations on the map. The device status is uploaded in real time by the onboard sensors.

[0046] In one embodiment, the personnel management module includes: a personnel positioning unit, which is used to determine the location information of the corresponding operator according to the relative distance between the preset signal station in the scrap steel yard and the positioning tag worn by the operator; a personnel standardization detection unit, which is used to identify and determine the number, type and working status of the corresponding operator based on the image of the operator in the scrap steel yard. Specifically, the current location can be displayed on the ArcGIS map. Each operator wears a work badge (the work badge can be set as a positioning tag) and is located by UWB. The number, type and working status of the operators in each area can also be counted. The personnel standardization detection unit can identify whether the operator is wearing standard clothes (safety helmets, labor protection shoes, etc.) based on the operator image information collected by the camera.

[0047] In one embodiment, the operation management module includes: an operation status display unit, which is used to record the operation status of the scrap steel yard, and the operation status includes: operation equipment records, operation personnel records, operation operation records performed by the operation personnel, operation environment monitoring records in each of the authority areas, and real-time status / position of the operation equipment; an early warning release unit, which is connected to the terminal, and is used to generate warning information according to abnormal operation conditions and output it to the corresponding terminal to remind the corresponding operation personnel to perform the specified operation. Specifically, the operation management module can summarize all operation equipment / personnel conditions, including all operations of the operation personnel during the operation process, the monitoring of the operation environment, the real-time status / position of the equipment, etc.; after summarizing all the conditions, it is displayed to the authorized management personnel through the display interface, and the management personnel judge whether there is an abnormality based on the displayed data. If there is an abnormality, an alarm can be issued and pushed to the terminal to remind the operation personnel. In another embodiment, data display can also be combined with ArcGIS map, and the operation personnel trajectory or the operation equipment trajectory can be judged according to the editing of the authority area in the map. Whether it crosses the authority boundary, the alarm information is automatically triggered and released to the terminal to remind the corresponding operation personnel. The specific warning release method can be set according to the actual application needs, and there is no restriction here.

[0048] In one embodiment, the terminal includes: an identity authentication unit, which is used to authenticate the authority of the operator according to the authentication method configured by the authority management module; an operation auxiliary unit, which is used to display the acquired operation environment information of the corresponding operation equipment and provide operation navigation; a fatigue detection unit, which is used to obtain the facial image of the corresponding operator in real time, and judge whether the fatigue value of the corresponding operator exceeds the set threshold by identifying the facial image features, and if it exceeds the set threshold, the preset warning information is activated. Specifically, the identity authentication unit verifies the authority of the operator according to the authentication method specified by the server (face recognition, password, verification code, etc.). Conventional operators use face recognition to identify whether they are designated operators (to prevent illegal shift replacement); when the face recognition device is abnormal, the password replaces the face recognition for verification, and the password is changed every day; when the operator is a temporary staff or hopes to be granted a single operation authority, the verification code can be used for authentication. The operation auxiliary unit is mainly used to enhance the operator's perception of the working environment and to warn of dangerous situations. Through ground and vehicle-mounted sensor monitoring, when a person / equipment approaches the operation area, it will be marked on the terminal screen and voice reminder will be given; during operation, the operation equipment will be located through GPS, and speeding and route deviation, etc. (voice reminder and report to the server), as well as alarm for entering unauthorized areas (report to the server). Some equipment can only travel on specified roads, otherwise it will damage the road. Some operation equipment is equipped with sensors to locate the posture of the equipment, and the operation instructions of the operator will also be uploaded during the operation. Once irregular operation is found, the operator will be warned in time and reported to the server. For example, when operating the steel grabbing equipment, the operator performs face recognition through the terminal; after the authority is passed, the equipment starts self-checking; if there is no abnormality in the self-checking, the surrounding environment is checked; after the whistle is sounded (if there is no such operation, it will be reported to the service end), it drives to the working position according to the regulations (driving on the designated non-hardened ground, the boom arm and the end clamp keep the designated position, and keep driving at a low speed); after starting the operation, it detects whether there are people / equipment in the working radius in real time, especially at night, which saves a lot of energy for the operator; when loading and unloading goods, the end sensor can obtain the scrap steel status of the dump truck cargo bucket, and the end clamp will alarm when it collides with the dump truck; after the operation is completed, the steel grabbing equipment drives to the designated parking position according to the regulations, adjusts to the designated posture (the end clamp is placed on the ground), and performs face recognition again to end this operation. The fatigue detection unit monitors the mental state of the operator. The scrap steel yard operates 7*24 non-stop, and the operator's work intensity is high, especially at night, and the energy will decline rapidly. The camera captures the operator's facial image in real time, and detects the operator's fatigue level through features such as the number of blinks and yawns. When the warning threshold is reached, the operator will be reminded through the speaker at the terminal and the warning will be uploaded to the server.

[0049] In one embodiment, the present invention further provides a scrap steel yard safety management method, which is used to implement the scrap steel yard safety management system described in the above system embodiment. Since the technical principle of the method embodiment is similar to the technical principle of the above system embodiment, the same technical details will not be repeated.

[0051] Step S01, according to the pre-defined permission area in the scrap steel yard, obtain the biometric identification features and / or operating equipment features in the corresponding permission area for permission verification, and the operating equipment includes: a steel grabber and a material transport vehicle;

[0052] Step S02, updating the position and status of the corresponding operating equipment on the pre-established scrap steel yard map, and monitoring the movement trajectory of the corresponding equipment;

[0054] Step S04, summarizes the work status, equipment status and work records of each operator, detects the working environment of the corresponding work equipment and the authority and work status of the operator operating the work equipment, and initiates a safety warning based on the detection results.

[0055] In summary, the present invention provides a scrap steel yard safety management system and method, which detects personnel clothing, personnel / vehicle entry authority detection and tracking, operation authority detection, fatigue detection, intrusion detection, etc. through image recognition (face recognition, license plate recognition); during the operation process, industrial cameras and laser radars are used to enhance the perception of the surrounding environment by operators, and timely alarms are issued when accidents are about to occur; the real-time status of the operating equipment is uploaded in real time through sensors, and functions such as power-on self-checking and monitoring the standardized operation of operators are completed.
