The specific embodiment
Referring to Fig. 1, the application's high-voltage hot-line work security alarm gloves are comprised of two of left and right insulating glove 1,2, because the common right hand is the conventional hand of operation, in order to reduce the wearing and tearing of gloves and to be convenient to check, detection alarm circuit is arranged on the forearm position of left hand gloves 1, specifically can be arranged on the medial inner side of forearm, also can be arranged on the forearm outside of health dorsad.
Detection alarm circuit comprises following part: electric field detection display device 3, magnetic field detection display 4, the integrated electric field detection display of electric field alarm lamp switch 5, magnetic field alarm lamp integrated magnetic field detection display switch 6, electric field voice guard 7, magnetic field voice guard 8, microprocessor 9(is arranged at detection alarm inside circuit, not shown in Fig. 1).
Fig. 2 is the system architecture of detection alarm circuit.
Electric field detection display device 3 continues testing environment electric field, electric field value is sent to microprocessor 9, microprocessor 9 judges whether electric field value surpasses alarm threshold value G1, and judge by security alarm intelligent algorithm whether electric field growth rate surpasses alarm threshold value G2, if electric field value surpasses alarm threshold value G1 or electric field growth rate surpasses alarm threshold value G2, microprocessor 9 is controlled conducting electric field voice guard 7 audio alerts, control the integrated electric field detection display of electric field alarm lamp switch 5 light source luminescents simultaneously, staff can select as required whether press switch 5 and check electric field value at that time, if need to check, press switch 5, audio alert and light source show closes, 3 of electric field detection display devices show current environment electric field value, facilitate staff to check and determine whether to need to do further security protection.When again pressing switch 5, electric field detection display device 3 will cut out demonstration, and electric field voice guard 7 carries out audio alert, and switch 5 light source luminescents are reminded staff's safety work.
Magnetic field detection display 4 continues testing environment magnetic field, magnetic field value is sent to microprocessor 9, microprocessor 9 judges whether magnetic field value surpasses alarm threshold value G3, and judge by security alarm intelligent algorithm whether magnetic field growth rate surpasses alarm threshold value G4, if magnetic field value surpasses alarm threshold value G3 or magnetic field growth rate surpasses alarm threshold value G4, microprocessor 9 is controlled conducting magnetic field voice guard 8 audio alerts, while controlling magnetic field alarm lamp integrated magnetic field detection display switch 6 light source luminescents, staff can select as required whether press switch 6 and check magnetic field value at that time, if need to check, press switch 6, audio alert and light source show closes, magnetic field detection display 4 shows current environment magnetic field value, facilitate staff to check and determine whether to need to do further security protection.When again pressing switch 6, magnetic field detection display 4 will be closed demonstration, and magnetic field voice guard 8 carries out audio alert, and switch 6 is luminous, remind staff's safety work.
Below security alarm intelligent algorithm is elaborated.Conventionally, changes of magnetic field is comparatively mild, is subject to external interference smaller, at distance high-voltage environment facies, to place far away, just can measure, and attenuation ratio is milder, signal function distance, and therefore detectable distance is longer.Electric field change is very fast, affected by environment larger, will attenuation ratio more serious if any barriers such as bodies of wall, when distance high-voltage environment is nearer, is more big changes, and detectable distance is shorter.As to take 220KV and 110KV environment be example, for central magnetic field intensity, 220KV and 110KV environment are basic identical, but electric field difference is larger, and the variation of combined magnetic field electric field just can be distinguished different hyperbaric environments.For another example, it is 220V or 380V that staff needs the ambient voltage of livewire work, but near it, there are high pressure, ultra-high voltage environment, before not approaching, the electromagnetic field that electromagnetic field intensity can produce apparently higher than 220V or 380V voltage, staff just can determine whether need to continue operation according to this as judgement, prevents from entering high-pressure area under unknown situation.The application passes through high voltage electric field, and the continuous monitoring in magnetic field utilizes electric field magnetic field different by change of distance simultaneously, can carry out intelligent decision to different safe distances, prevents that staff is strayed into the high-pressure area that surpasses original plan hot line job.By analyze electric field or magnetic field current size, change curvature and attenuation rate intelligent decision safe distance, if the variation curvature in electric field or magnetic field is greater than early warning value and attenuation rate, in safe range, do not show that staff's forward high-pressure area moves.
If start test point as time 0 point, sample frequency is 10Hz, and 5 averages are as measuring point Ei, within continuous 5 seconds, without significant change, retains the mean value new record of laying equal stress on, if there is significant change to calculate its curvature and attenuation rate, the point of establishing record is:
| Time | T1 | T2 | T3 | T4 | T5 | T6 | T7 | T8 | T9 | T10 |
| Electric field | E1 | E2 | E3 | E4 | E5 | E6 | E7 | E8 | E9 | E10 |
