The process of statistical analysis comprises information such as operation information, operation time, alarm records, operation and equipment data, operator codes, equipment codes, contact information, field pictures and the like. For the alarm records, the alarm reasons can be analyzed, such as human errors caused by irregular operation, emergencies caused by field conditions or emergencies, and classified statistics can be carried out according to information such as operation time intervals, working years of operators and the like.
On the basis of the above embodiment, fig. 2 is a flow chart of field safety management according to an embodiment of the present invention, as shown in fig. 2, before work, an employee card needs to be identified, an intelligent seat belt is selected (an operator independently selects whether to wear a seat belt with a portable camera according to a work condition), and the intelligent seat belt is turned on to confirm whether the state of the equipment is in compliance, and if the charge amount of the seat belt is insufficient or damaged, an alarm is given. The field monitoring device reads the employee card, uploads information such as an employee code, an intelligent safety belt code, operation time, operation content, the height of the field monitoring device, safety belt charge and the like to the server, and uploads information such as the height of the safety belt, the height of the air pressure calibrator, operation alarm and the like to the server in real time.
After the safety belt is worn, the D-shaped ring is used for detecting the tightness of the safety belt, the intelligent rope grabbing device hanging ring is used for detecting whether the intelligent rope grabbing device hanging ring is connected with a rope grabbing device or not, and the intelligent rope grabbing device hanging ring feeds back signals to the portable controller respectively, and the portable controller feeds back the signals to the field monitoring device and the background server. In the process, if the wearing condition of the operator is detected to be not in compliance, the safety belt gives an alarm prompt, and the operator can perform high-altitude operation after adjusting the compliance.
The steps of detecting whether the equipment state and the wearing condition are in compliance are shown as follows, fig. 3 is a flow chart of detecting the equipment state and the wearing condition described in an embodiment of the invention, as shown in fig. 3, firstly, whether the electric quantity of the equipment is sufficient is detected, if the electric quantity is insufficient, an alarm is given and uploaded to a server, if the electric quantity is sufficient, whether the tightness degree of a safety belt is qualified is detected, if the tightness degree is not qualified, the alarm is given and uploaded to the server, if the safety belt is qualified, whether a rope grabbing device is connected with the safety belt is detected, if the safety belt is not connected, the alarm is given and uploaded to the server, if the safety belt is connected, the alarm is not given, and a single judgment flow is ended.
In the above steps, after the alarm, the operator needs to adjust the alarm until the non-compliance condition corresponding to the alarm item is detected to be a compliance state, and then the alarm is stopped.
After the safety belt reaches an operation point, an operator can hang the intelligent hook on firm hanging points such as a metal rod, and the intelligent safety belt can provide the protection effect of an ordinary safety belt.
Under the open mode, the system continuously carries out height detection, and when detecting that the operating personnel height is higher than preset safe height (2m), the portable controller controls the suspension state detector on the intelligent hook to open, and the suspension state detector detects whether the hook is on the hanging point, and if not, then carries out alarm prompt until the operating personnel hangs the hook on the hanging point. After the hook is hung, the portable controller controls the locking mechanism to be opened, the hook cannot be unlocked at the moment, and unhooking detection, falling detection and height detection are continuously carried out. If the system detects that the descending speed of the operator is greater than 1m/s, the falling event is judged to occur, and at the moment, the portable controller gives an alarm and transmits the alarm to the field monitoring device and the background server.
In the operation process, when an operator needs to unlock due to operation requirements, an electric unlocking button needs to be pressed, the portable controller sends an immediate unhooking request to the management platform, after receiving a feedback approval unhooking request of the manager, the locking mechanism is closed, the hook is automatically unlocked, the operator can take the hook down from a hanging point, the single operation flow is finished at the moment, and the operator can close the equipment.
When an operator works at a position higher than a preset safety height (2m), and needs to be unlocked in a sudden emergency situation, the emergency unlocking button can be immediately pressed, and the hook is mechanically unlocked at the moment and is not limited by the locking mechanism, so that the operator can conveniently escape emergently. Meanwhile, the portable controller sends emergency unlocking information to the field controller and the management platform.
In the operation process, the camera transmits the shooting picture to the field controller and the management platform in real time.
At the management platform end, managers can comprehensively master the operation state, operation height, equipment information, operation discipline, abnormal state alarm information and the like of operators in real time, effectively supervise, and can timely handle emergency conditions to ensure the personal safety of the operators.
