Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The application provides a safety monitoring method of belt conveying equipment.
It should be noted that the safety monitoring method of the belt conveying apparatus provided by the present application is not limited to its main implementation. Alternatively, the main body of the safety monitoring method of the belt conveyor apparatus may be a monitoring terminal 200 electrically connected to the belt conveyor apparatus 20. Optionally, the execution subject may be the processor 210 in the monitoring terminal 200.
As shown in fig. 1, in an embodiment of the present application, the safety monitoring method of the belt conveying apparatus includes the following steps S110 to S150:
s110, acquiring the user authority of the monitoring target 100, and judging whether the user authority of the monitoring target 100 is smaller than a preset operation authority.
Specifically, the monitoring target 100 may be installed with a pass. The pass and the monitoring terminal 200 may communicate through Near Field Communication (NFC) technology. The monitoring terminal 200 may acquire the user right stored in the pass. Alternatively, the monitoring target 100 may wear a safety helmet, and the pass may be provided in the safety helmet.
And S120, if the user authority of the monitoring target 100 is smaller than the preset operation authority, acquiring the position coordinate of the monitoring target 100.
Specifically, the preset operation authority may be preset by a manager of the belt conveyor apparatus 20. The user authority may also be preset by a manager of the belt conveyor apparatus 20. If the monitoring terminal 200 determines that the user right of the monitoring target 100 is smaller than the preset operation right, it indicates that the user right of the monitoring target 100 is lower. It is understood that the monitoring terminal 200 needs to perform further accurate monitoring of the monitoring target 100.
Optionally, if the monitoring terminal 200 determines that the user right of the monitoring target 100 is greater than or equal to the preset operation right, the subsequent steps are interrupted. If the monitoring terminal 200 determines that the user right of the monitoring target 100 is greater than or equal to the preset operation right, it indicates that the user right of the monitoring target 100 is higher. It is understood that the monitoring terminal 200 determines that the monitoring target 100 is a highly-qualified manager familiar with the belt conveyor apparatus 20 without performing a subsequent monitoring step.
S130, determining whether the monitored target 100 is in a preset dangerous area according to the position coordinates of the monitored target 100.
Specifically, the preset dangerous area may be previously divided by a manager of the belt conveyor apparatus 20.
S140, if the monitored target 100 is in the preset dangerous area, further determining whether the monitored target 100 is a human.
Specifically, if the monitoring terminal 200 determines that the monitored target 100 is in the preset dangerous area, it indicates that the monitored target 100 is in a dangerous state, and the next accurate monitoring is required.
Optionally, if the monitoring terminal 200 determines that the monitoring target 100 is not in the preset dangerous area, the subsequent steps are interrupted. If the monitoring terminal 200 determines that the monitored target 100 is not in the preset dangerous area, it indicates that the monitored target 100 is in a safe state, and the monitoring of the next step is not needed.
S150, if the monitored object 100 is a human being, sending an alarm message to the management terminal 300 to prompt the management terminal 300 that the human being exists in the preset dangerous area.
Specifically, if the monitoring terminal 200 determines that the monitoring target 100 is a human, it indicates that the belt conveyor 20 has a high probability of generating an accident under the misoperation of the monitoring target 100. At this time, the management terminal 300 needs to be alerted. The management terminal 300 may be an upper computer, and the monitoring terminal 200 may be a lower computer.
Alternatively, if the monitoring terminal 200 determines that the monitoring target 100 is not a human, the process returns to the step S110. If the monitoring terminal 200 determines that the monitored object 100 is not a human, it indicates that the probability of an accident occurring after the belt conveyor apparatus 20 is started is low. For example, it is possible that the monitoring target 100 is only a helmet, which is placed in a preset dangerous area of the belt conveyor apparatus 20. No human being is in the preset danger area. At this time, no message may be sent back, and the monitoring is continued by returning to the step S110.
Optionally, if the monitoring terminal 200 determines that the monitoring target 100 is not a human, a prompt message is sent to the management terminal 300 to prompt the management terminal 300 that a non-human exists in the preset dangerous area. At this time, a prompt message may be returned to the management terminal 300 to notify the manager of the process. However, only ordinary prompt messages are returned, and no alarm messages are returned.
In this embodiment, the operation authority of the monitoring target 100 is identified by acquiring the user authority of the monitoring target 100 and the user authority and the preset operation authority of the monitoring target 100. When the user authority of the monitoring target 100 is high, the monitoring is stopped, and the monitoring efficiency is improved. By judging whether the monitoring target 100 is in the preset dangerous area or not, the specific area of the belt conveying equipment 20 is monitored, and the monitoring precision is improved. By judging whether the monitoring target 100 is human or not, the invalid monitoring of the non-human monitoring target 100 is avoided, and the monitoring efficiency is further improved.
In an embodiment of the present application, the step S110 includes the following steps S111 to S113:
and S111, acquiring the user identity information of the monitoring target 100.
Specifically, the monitoring target 100 may be installed with the pass mentioned in the foregoing. The user identity information may be stored within the pass. The pass and the monitoring terminal 200 may communicate through Near Field Communication (NFC) technology. The monitoring terminal 200 may obtain the user identity information stored in the pass.
S112, analyzing the user identity information to obtain the user authority in the user identity information.
Specifically, the monitoring terminal 200 may parse the user identity information. The user identity information includes the user right. The user identity information may further include one or more of a user's ID number, a user's name, a user's gender, and a user's age,
S113, extracting an authority list, and acquiring the preset operation authority in the authority list. And further, judging whether the user authority is smaller than the preset operation authority.
Alternatively, the permission list may be stored locally in the monitoring terminal 200. Alternatively, the authority list may be stored in the management terminal 300. The authority list is set by the manager of the belt conveyor apparatus 20. The permission list may include a plurality of operational permissions, the plurality of operational permissions being ordered from top to bottom. The manager of the belt conveying apparatus 20 may set a certain operation authority as the preset operation authority. When the user authority is greater than the preset operation authority, the monitoring terminal 200 determines that the operation authority of the monitoring target 100 is higher, and terminates the subsequent monitoring step. Otherwise, continuing the subsequent monitoring step.
For example, the authority list includes level 1, level 2 …, level 9, and 9 operation authorities. The operation authority of level 1 is the highest, and represents the operation authority of the supervisor. The operating authority of level 2, next to that of the advanced mechanic, represents the operating authority of the advanced mechanic. The operation authority of the level 9 is the lowest, and represents the operation authority of the external person. The operation authority of the level 4 can be set as the preset operation authority, which represents the operation authority of the middle-level technician. And when the monitoring terminal 200 judges that the user authority is smaller than the operation authority of the level 4, continuing the subsequent steps.
In this embodiment, the operation right of the monitoring target 100 can be identified by obtaining the user right in the user identity information of the monitoring target 100, so that the monitoring is stopped when the user right of the monitoring target 100 is high, and the monitoring efficiency is improved.
In an embodiment of the present application, the step S120 includes the following steps S121 to S122:
s121, if the user permission of the monitored target 100 is smaller than the preset operation permission, sending an instruction for acquiring the position coordinate of the monitored target 100 to a positioning device 220. The monitoring target 100 carries the positioning device 220.
Specifically, the monitoring target 100 may further carry a positioning device 220. When the monitoring terminal 200 determines that the user authority of the monitoring target 100 is smaller than the preset operation authority, the position coordinate of the monitoring target 100 is further acquired.
S122, obtaining the position coordinates of the monitoring target 100 sent by the positioning device 220.
Specifically, the positioning device 220 may be provided with a GPS module for acquiring position coordinates. After the positioning device 220 collects the position coordinates of the monitoring target 100, the position coordinates of the monitoring target 100 are sent to the monitoring terminal 200.
In this embodiment, the monitoring terminal 200 provides a data basis for the subsequent monitoring terminal 200 to determine whether the monitoring target 100 is in a preset dangerous area by acquiring the position coordinate of the monitoring target 100 sent by the positioning device 220.
In an embodiment of the present application, the user identity information is stored in the positioning device 220.
Specifically, the user identity information may also be stored not in the pass but in the positioning device 220. It can be understood that the positioning device 220 can obtain the position coordinates of the monitoring target 100 and the user right of the monitoring target 100. For example, the positioning device 220 is disposed in a helmet, and all constructors or outside visitors wear the helmet. When the constructor or the external observer approaches the belt conveyer 20, the positioning device 220 in the safety helmet can simultaneously acquire the position coordinates and the user authority of the constructor or the external observer.
In this embodiment, the user identity information is stored in the positioning device 220, so that the positioning device 220 can obtain the position coordinate and the user permission of the monitoring target 100 at the same time, and the design cost is saved.
In an embodiment of the present application, the step S130 includes the following steps S131 to S133:
s131, obtaining the coverage of the position coordinates of the preset dangerous area from the management terminal 300.
Specifically, the preset dangerous area position coordinate coverage may be divided in advance by a manager of the belt conveyor apparatus 20.
S132, determining whether the position coordinate of the monitoring target 100 falls within the position coordinate coverage of the preset dangerous area.
In particular, the belt conveyor apparatus 20 may be provided with a GPS module. The GPS module acquires a position coordinate coverage range of the preset dangerous area and uploads the position coordinate coverage range to the management terminal 300. The monitoring terminal 200 acquires the position coordinate coverage of the preset dangerous area from the management terminal 300. Further, the monitoring terminal 200 compares the position coordinate of the monitoring target 100 with the position coordinate coverage of the preset dangerous area.
S133, if the position coordinate of the monitored target 100 falls within the position coordinate coverage of the preset dangerous area, determining that the monitored target 100 is in the preset dangerous area, and executing the step S140.
Optionally, if the monitoring terminal 200 determines that the monitoring target 100 does not fall into the preset dangerous area, the subsequent steps are interrupted. If the monitoring terminal 200 determines that the monitored target 100 does not fall into the preset dangerous area, it indicates that the monitored target 100 is in a safe state, and the monitoring of the next step is not needed.
In this embodiment, whether the position coordinate of the monitoring target 100 falls within the position coordinate coverage of the preset dangerous area is judged, so that the specific area of the belt conveyor 20 is monitored, and the monitoring precision is improved.
In an embodiment of the present application, the step S140 includes the following steps S141 to S144:
s141, if the monitored target 100 is in the preset dangerous area, sending a thermal image scanning instruction to the thermal infrared imager 230.
Specifically, the monitoring terminal 200 may include the thermal infrared imager 230. The thermal infrared imager 230 may also be a stand-alone device. The thermal infrared imager 230 is disposed in the preset dangerous area and connected to the belt conveying device 20. The thermal infrared imager 230 is also connected to the monitoring terminal 200. When the monitoring terminal 200 includes the thermal infrared imager 230, the execution subject of the steps S141 to S144 is the processor 210 of the monitoring terminal 200.
When the thermal infrared imager 230 is an independent device, the main execution objects of the steps S141 to S144 are the monitoring terminal 200.
S142, after the thermal infrared imager 230 scans the preset dangerous area to generate a thermal image, acquiring the thermal image sent by the thermal infrared imager 230.
Specifically, the thermal infrared imager 230 has a thermal image scanning range. The thermal image scanning range covers the preset dangerous area. After the thermal infrared imager 230 scans the preset dangerous area to generate a thermal image, the thermal image is sent to the processor 210 of the monitoring terminal 200. The thermal infrared imager 230 scans the preset dangerous area to generate a thermal image of the monitoring target 100.
S143, extracting a human body thermal image template, and comparing the thermal image with the human body thermal image template to generate a coincidence value of the thermal image and the human body thermal image template.
Specifically, the human thermal image template is generated by a manager of the belt conveyor apparatus 20 through a thermodynamic model in advance. The human thermal image template can be stored locally in the monitoring terminal 200. The human thermal image template may also be stored in the management terminal 300.
S144, if the coincidence value of the thermal image and the human thermal image template is greater than or equal to the preset coincidence value, determining that the monitoring target 100 is a human, and executing the step S150.
Specifically, the preset coincidence value may be calculated and generated by the thermodynamic model, and is in accordance with the determination rule of the human thermal image. When the coincidence value of the thermal image and the human thermal image template is high enough, that is, greater than or equal to the preset coincidence value, it may be determined that the monitoring target 100 is a human.
In this embodiment, the thermal imager 230 scans the preset dangerous area to generate a thermal image, and compares the thermal image with the human thermal image template, so as to determine whether the monitoring target 100 is human, thereby avoiding invalid monitoring of the non-human monitoring target 100 and further improving monitoring efficiency.
In an embodiment of the present application, a face recognition device or a video monitoring device may be disposed in the preset dangerous area to determine whether the monitored target 100 is a human being. The video monitoring device also has a function of taking pictures or recording videos so as to keep evidence of illegal approach of the monitoring target 100 to a preset dangerous area of the belt conveying equipment 20, thereby facilitating later responsibility tracing.
In an embodiment of the present application, before the step S110, the method further includes the following steps:
