Description

Technical Field

[0002] During the industrial production process in the factory, there are often some dangerous areas that require special attention from factory personnel. At the same time, the factory also needs to manage the production operations of factory personnel. Most factories currently still use traditional safety management methods, such as inspection and clocking in, marking out dangerous areas and setting up warning signs, and regularly conducting safety training for personnel.

[0003] A Chinese patent with publication number CN111811516B discloses a factory personnel positioning and safety warning system, which is equipped with a positioning information collection module, and can collect the location information of factory personnel in real time. Through the three-dimensional management module and the information calculation module, the update and action path calculation are performed, and the location is mapped to the coordinate system to improve the accuracy of positioning. The calculation results of the factory personnel's safety status are promptly fed back to the display module, so that the system can grasp the safety status of the factory personnel at the first time, make safety reminders, and effectively improve the effectiveness of safety management. When a safety problem occurs, an alarm can be issued to the factory personnel in time to minimize manpower losses. At the same time, it can make timely responses to sudden safety problems and improve the utilization rate of various resources in the factory.

[0066] Step 2: Obtain the dangerous equipment in the working area and analyze the risk level of the equipment. According to the risk level of the equipment, assign the dangerous area of ​​the equipment to obtain the risk distribution of the equipment. Superimpose the risk distribution of all equipment to obtain a comprehensive risk distribution map. Divide the area within the comprehensive risk distribution map into dangerous coordinates, and divide the area outside the comprehensive risk distribution map into normal coordinates.

[0067] Step 3: Analyze the personnel's action route based on the personnel's stay coordinates in the work area, generate the personnel's activity trajectory based on the action route, generate the activity area based on the activity trajectory, and determine whether the personnel's action trajectory is within the safety coordinate range based on the activity trajectory.

[0068] Step 4: Compare the movement trajectory of the on-site personnel with the matching work area of ​​the personnel to determine whether the movement trajectory of the personnel is dangerous. When the movement trajectory of the personnel is in the matching work area, no alarm is triggered.

[0069] Step 5: When a person's movement trajectory enters a work area that does not belong to him and the stay time exceeds a certain length, a second-level alarm will be issued to remind the person to return to his work area. When a person's movement trajectory enters a dangerous area, a first-level alarm will be issued to remind the person that there is danger in the current area and he should evacuate immediately.
