Abstract
The utility model discloses a passive signal generator which comprises strong magnetic steel and a carrier. The utility model is characterized in that the strong magnetic steel is arranged longitudinally and laterally at intervals by polarity and is placed on the carrier. The utility model has the characteristics that signals are strong and can not be easily shielded, the specific position of a target can be accurately detected, and the utility model has operation convenience and high speed. The utility model is widely used in special rescue.
Description
One, technical field: the utility model relates to signal generator, particularly a kind of passive signal generator.
Two, background technology: existing rescue signal generator mainly is an infrared generator, utilize the thermally sensitive characteristic of infrared ray sensor, can detect people's body temperature, but personnel are embedded in ruins following times, because people's body temperature can't pass to infrared ray sensor by ruins, so can't detect buried person person's particular location.Be example with Hengyang big fire just, tens fire fighters are embedded among the ruins of collapsing, and have almost used all advanced instruments that can survey buried person person all, still can't detect buried person person's particular location, have lost best rescue opportunity, suffer heavy losses.
Three, summary of the invention: the purpose of this utility model just provides a kind of passive signal generator, shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art.
Passive signal generator described in the utility model comprises high magnetic steel and carrier, and described high magnetic steel is as signal source, and high magnetic steel, is placed on the carrier vertically with laterally being arranged in apart from one another by ground with polarity.
Wherein, the carrier of described high magnetic steel is a waistband shape structure, and its two ends are separately installed with buckle and snap collar, and high magnetic steel is installed at the middle part.
The utility model has following advantage compared with prior art:
1, owing to utilizes magnetic signal to be difficult for the characteristic of conductively-closed, high magnetic steel with polarity vertically with laterally being arranged in apart from one another by ground, no matter how carrier is placed, it is in vertical direction that the NS of the high magnetic steel that arrangement is good extremely always has one side, use the magnetic signal detector, just can accurately detect buried person person's particular location, catch best rescue opportunity, reduce the loss to greatest extent.
2, easy to operate, speed is fast, and the efficient height need not the energy, and cost is low.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Five, embodiment:
With reference to accompanying drawing, a kind of passive signal generator comprises high magnetic steel 2 and carrier 3.High magnetic steel, is placed on the carrier vertically with laterally being arranged in apart from one another by ground with polarity.
The carrier of high magnetic steel 2 is a waistband shape structure, and its two ends are separately installed with buckle 4 and snap collar 1, and high magnetic steel is installed at the middle part.
Claims (2)
1, a kind of passive signal generator comprises high magnetic steel and carrier, it is characterized in that described high magnetic steel with polarity vertically with laterally being arranged in apart from one another by ground, be placed on the carrier.
2, passive signal generator according to claim 1 is characterized in that described carrier is a waistband shape structure, and its two ends are separately installed with buckle and snap collar, and high magnetic steel is installed at the middle part.
