Spatial self-contained electromagnetic waves are selected as a detection medium, the electromagnetic waves are widely distributed, so the relatively good monitoring effect is acquired. The electromagnetic waves have advantages of strong penetrability and good directivity, so the spatial self-contained electromagnetic wave monitoring security system are influenced to a small degree, concealed hypothesis can be carried out, and the spatial self-contained electromagnetic wave monitoring security system has advantages compared with an infrared monitoring system in the prior art. The spatial self-contained electromagnetic wave monitoring security system can be applied in a plenty of occasions as the new-generation electronic fence technology, such as, in government agencies, hotels, mansions and shopping malls; as the spatial self-contained electromagnetic wave monitoring security system is not liable to be found, the spatial self-contained electromagnetic wave monitoring security system has special functions in occasions, such as jewelry exhibition sites and banks having special security requirements.
Description
Technical field
The utility model relates to the own electromagnetic wave monitoring in a kind of space safety-protection system, belongs to radio communication and safety-security area.
Background technology
Existing monitoring and alarming system is mainly infrared monitoring warning system, adopts infrared ray as monitoring medium.Infrared monitoring warning system is divided into again active and passive two large classes.Wherein active infrared monitoring and alarming system is to comprise to transmit and receive infrared ray.In the time having people or object to block, the infrared ray sending can not be received, and passive infrared monitoring and alarming system is with infrared photography seat in the plane main body, and the infrared radiation imaging of sending according to object self reaches the object of monitoring alarm.Passive infrared penetration power is poor, and the infrared radiation of human body is easily blocked, and is difficult for being received by alarm the interference that is subject to radio-frequency radiation.And when environment temperature and human body temperature approach, detection and sensitivity obviously decline, and sometimes cause malfunctioning in short-term.Active infrared alarm also has similar shortcoming.
IR alarm system is disturbed by various thermals source and sunlight source easily, and environmental factor is restricting the performance of monitoring and alarming system.For now, the IR alarm system power consumption on market is large, and cost is high, and easily breaks down and red sudden and violent phenomenon, and result of use is not very desirable.
Also have by electromagnetic wave and carry out monitoring alarm in the market, but this class is independently to send electromagnetic wave to form electric field region, thereby can detect that moving target enters electric field region and reports to the police.Autonomous transmission electric field causes cost to increase, and power consumption also increases, and powerful electric field radiation also can cause potential impact to human body in addition, increases the limitation using under Liao Qi community and home environment.
Utility model content
Near utility model object: in order to overcome the deficiencies in the prior art, the utility model proposes the own electromagnetic wave monitoring in a kind of space safety-protection system, the own electromagnetic wave in native system monitoring space, enters and cause that electromagnetic variation reports to the police it target object.System power dissipation is low and be subject to such environmental effects little, can carry out hidden burying underground, and electronics safety-protection system of new generation is provided.
Technical scheme:
For achieving the above object, the technical solution adopted in the utility model is:
The own electromagnetic wave monitoring in a kind of space safety-protection system, is made up of following part: antenna, wave filter, low noise amplifier, power detector, processor, camera, sound and light alarm and remote alarms successively.The wherein own electromagnetic wave in antenna reception space, wave filter is bandpass filter, leach and need frequency range to be processed, low noise amplifier amplifies signal, power detector carries out detection to amplifying signal, processor gathers and carries out preset range judgement detection output, if exceed preset range, the camera, sound and light alarm and the remote alarms that provide alarming result and trigger rear end start takes pictures or warning function.
