Description
Technical field:
The present invention relates to a kind of electronic enclosure system and localization method thereof with radio tracking, location and warning.
Background technology:
Common in the market radio tracking positioning equipment is usually based on technology such as GPS, GSM and WCDMA; has the bearing accuracy height; the advantage that the track and localization region is wide; but exist system complex cost height, the very much not portable band of volume, the short shortcoming of the big stand-by time of power consumption; target can't receive gps signal indoor moving in addition; GSM and WCDMA can't be used in the zone that does not have in the mobile base station to cover, so the said equipment and be not suitable for the radio tracking location in some specific cell territory.The detector of common in the market fence usually based on infrared ray block, principles such as pyroelectricity, wired shake-up, its shortcoming is that the infringement of animal can cause false alarm, and can't discern the objectives of invading fence.The detector of the wireless electron fence on the market still usually based on infrared ray block, principles such as pyroelectricity, wired shake-up, only adopt radio communication between detector and the Surveillance center.
Common radio tracking positioning system can only carry out track and localization to the moving target in certain region scope, there is not the border, target area to limit the monitoring positioning function of (being fence), and common fence is reported to the police can only be subjected to invading to fence the time, the electronics moving target in the fence is not carried out the zone location function, more can not discern concrete infringement target.
Present safety-protection system (as prison monitoring, important item storage monitoring, miner's search and rescue, the patient of hospital monitoring etc.) is mainly based on the video monitoring technology, equipment investment is bigger, cause omission because of the monitor staff is tired with carelessness easily when monitoring objective is a lot, and because the frequent false alarm of fence causes monitor staff's thought paralysis, thereby monitoring effect is reduced greatly.
