Embodiment 1
[0022] If the live equipment is located above the head of the maintenance operator, the precise positioning method for the substation maintenance operator includes the following steps:
[0023] S1: Arrange positioning sensors and alarms on the head, arms, waist, legs, and feet of the maintenance workers, and locate the connection between the head, arms, waist, legs, feet and live equipment of the maintenance workers in real time The distance H between;
[0024] S2: During the maintenance operation, with the change of the posture of the maintenance operator, the positioning data of the body parts beyond the head is used as the reference point for calculation, and the shortest distance H1 between the head or arm of the maintenance operator and the live equipment is judged in real time;
[0025] S3: Comparing the relationship between the shortest distance H1 and the safety distance H2, if the shortest distance H1 between the head or arm of the maintenance operator and the live eq...
Embodiment 2
[0027] If the live equipment is located in front, rear or left or right of the maintenance workers, the precise positioning method for the substation maintenance workers includes the following steps:
[0028] S1: Arrange positioning sensors and alarms on the head, arms, waist, legs, and feet of the maintenance workers, and locate the connection between the head, arms, waist, legs, feet and live equipment of the maintenance workers in real time The distance H between;
[0029] S2: During the maintenance operation, as the posture of the maintenance operator changes, the location data of the body part farthest beyond the waist is used as the reference point for calculation, and the relationship between the head, arm, waist, leg, or foot of the maintenance operator is judged in real time. The shortest distance H1 of live equipment;
[0030] S3: Comparing the relationship between the shortest distance H1 and the safety distance H2, if the shortest distance H1 of any body part of t...

Abstract
The invention discloses an accurate positioning method for a transformer substation overhaul operation person. The method comprises the following steps: positioning a nearest distance between the head, the arms, the waist, the legs and the feet of the overhaul operation person and electrically charged equipment in real time; if the nearest position of any position of the body of the operation person is smaller than a safe distance, giving an early warning. According to the accurate positioning method, the distance between the head, the arms, the waist, the legs and the feet of the overhaul operation person and the electrically charged equipment is positioned in real time, a calculation reference point is regulated in real time according to the gesture change of the person in an overhaul operation process so as to determine the nearest distance between each position of the overhaul operation person and the electrically charged equipment, the position of the overhaul operation person canbe accurately monitored in real time in the overhaul operation process, a situation that a user enters an electrically charged region by mistake and touches the electrically charged equipment by mistake due to negligence can be effectively avoided, and therefore, the personal safety of the overhaul operation person and the safety of the overhaul operation can be effectively guaranteed.
Description
technical field [0001] The invention relates to the field of substation operation and maintenance, in particular to a precise positioning method for substation maintenance operators. Background technique [0002] There are many types of substation equipment, and the structure is not fixed. Compared with the line, the maintenance operation environment is more complicated, and the maintenance operation process is more cumbersome. If the position of the operator is not monitored, it is easy to enter the live interval (mistouching the live equipment) due to negligence or other reasons. It is easy to cause safety accidents, so the safe distance between personnel, machines and equipment should be regulated during maintenance operations. [0003] According to the "State Grid Corporation Electricity Safety Work Regulations", the safe distance between the normal range of activities of the staff and the live parts of the equipment during work: [0004] Voltage level (kV) ...
