Description
Technical field
The present invention relates to the netted deployment radar of multinode radar networking is used, to realize that the detection to indoor objects belongs to room
The fields technical fields such as interior management, smart home, specially a kind of indoor detection method using Distributed Network Radar.
Background technique
Radar perception is a kind of wireless aware technology.By analyzing the target echo characteristic received, extracts and find mesh
Target position, shape, kinetic characteristic and motion profile, and can further infer that the feature of target and environment.It acts on class
It is similar to the eyes and ear of the mankind.
Compared with other sensors, radar perception has many unique advantages.For example, compared with visual sensor, thunder
Up to not influenced by bright and dark light, there is the ability for penetrating shelter, can preferably protect individual privacy;With ultrasonic technique phase
Than the distance of radar perception is farther, and will not damage to humans and animals.
Radar perception can support application scenarios very rich.For example, millimetre-wave radar has just been widely used in

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment, referring to Fig. 1, the present invention provides a kind of technical solution: a kind of interior using Distributed Network Radar
Detection method, comprising the following steps:
By using multiple node radars, then each node radar is deployed in respectively above indoor each region, is used for
Physical activity in the regional scope is detected；
Each node radar covers the regional scope of a small pieces, and multi-section node radar complex forms reticular structure together, more
Portion's node radar is merged by information, so that the entire indoor detection of equivalent covering is realized, for improving the accurate of detection performance
Property and the sensitivity to target acquisition；
The radar central controller is used to collect the detection information of each node radar, after information is merged, carries out to the position of people
It determines, then the activity of people is detected and analyzed according to temporal information and location information.
Referring to Fig. 2, radar detector exports the low level pulse of specified time when someone's activity in detection zone,
After radar central controller receives level pulse triggering, data analysis is carried out, checks whether the personnel have occurred in the area, i.e.,
Whether the personnel are in " there are the duration " (configurable, factory default 10S), if said in " there are the duration "
Bright be the personnel is triggering caused by continuously active after entering the region, when re-starting delay meter, after timing, and thunder
Journalist has had left the region on up to central controller.
If not illustrating that people is to have just enter into the touching caused by radar detector behind the region in " there are the duration "
Hair, it is movable in the region that radar central controller should report someone to enter to RCU, then starts " there are the duration " timing, directly
To timing, journalist has had left the region on radar central controller.
Fig. 3-6 is please referred to, interior is mainly divided into four fundamental regions: Lang Qu, toilet, bathroom and sitting and lying area, wherein
Lang Qu, toilet and bathroom are zonule, the region sitting and lying Qu Wei great；
A small range radar detedtor is respectively installed in each zonule, one or two a wide range of radar is optionally installed in big region
Detector, for being covered to complete range.
Wherein, the radar detedtor is mounted on the top of ceiling, and the shell of radar is placed close to ceiling, thunder
The antenna surface reached down so that the microwave signal of radar detedtor emits down, the case where capable of incuding below smallpox.
Wherein, while reducing penetration performance, it is ensured that radar detedtor is ceiling mounted, and detect away from
It is suitable from also, it also to avoid other electromagnetic signal interference from interfering radar detedtor and accidentally touch, so selecting
10.525GHz radar.
Wherein, the radar detedtor mainly uses the antenna of MD1750C, because the antenna of the model does not have size folder
Angle is suitble to square-folded region, so meeting our application scenarios demand, can be improved radar detedtor to indoor range
Interior detection performance.
The node radar detedtor is separately mounted to above the ceiling of corresponding region, then by 4P telephone wire and
RJ11 socket and radar central controller, which carry out signal connection, can trigger radar detedtor, then thunder when someone's activity in certain region
Low level pulse is issued up to detector to radar central controller.
The radar central controller is connected by 485 cablings with RCU, the RCU in conjunction with other sensors information, thus
Control indoor equipment.
When someone's activity of certain region, radar central controller receives the low level pulse of radar detedtor sending, then thunder
Data are analyzed up to central controller, then report certain region someone movable to RCU, RCU is in conjunction with other sensors to interior
Equipment carry out switch control, such as signal light control.
Wherein, the parameter of the radar detedtor includes detection range and triggering duration.
Monobus is used by the communication in radar detedtor and central controller, the parameter letter of radar detedtor can be configured
Breath can remotely be adjusted the detection range of radar detedtor and triggering duration, be easy to use.
Wherein, the radar central controller is electrically connected by 485 cablings with electric power controller, the electric power controller
It is controlled for the use to light.
Working principle: then the invention is installed respectively by using deployment multinode radar in each region indoors
There is node radar, forms reticular structure, each node radar covers a small region, and multi-section node radar is merged by information,
It realizes the entire indoor detection of equivalent covering, ensure that detection performance and the sensitivity to target acquisition, and node radar
Using the radar of 10.525GHz, the penetration performance of radar is not only reduced, and guarantees radar detedtor being mounted on ceiling
When upper, detecting distance is also suitable, also reduces other electromagnetic signal interference interference caused by radar detedtor and accidentally touches；Work as radar
When detector senses someone's activity, GPIO outputs level signals, on Real-time Feedback to radar central controller, radar central controller passes through
After certain logic analysis processing, discovery region from someone become nobody or nobody become someone when, it is anti-by 485 serial communications
Feed RCU, and RCU controls indoor equipment in conjunction with the information of other sensors,
