Description
Technical field
The invention patent relates to one kind for after shake in scene, part trapped person can not normal movement simultaneously its mobile phone without
Method passes through situations such as GPS positioning, using the corresponding application program of mobile phone built in mobile communication base station and trapped person's mobile phone,
To treat the system and method that trapped person is positioned in rescue region.
Background technique
China's national territorial area is vast, but the earthquake zone covered simultaneously is also more, and the ground such as Sichuan Yunnan often occur different etc.
The earthquake of grade.Natural calamity not can avoid, but carrying out timely and effectively rescue work after calamity then can as far as possible
The wounded are rescued, are retrieved a loss.It after the earthquake, often happens someone will member is trapped, rescue personnel is often at this time
It is searched and rescued using the rescue method of blanket type, a large amount of manpower and material resources would generally be expended in this way.And in view of nowadays intelligent
The high popularity rate of mobile phone, can be by the position by positioning intelligent mobile phone come the position of indirect addressing personnel.
Simultaneously, it is contemplated that the signaling distances such as bluetooth, WIFI are closer, using mobile communication signal, i.e., using mobile logical
Letter base station can make rescue coverage area wider.In this way, using mobile communication signal, in combination with built in trapped person's mobile phone
The search-and-rescue work of personnel can be completed in application program.
Based on information above, the invention patent, which is completed, provides signal of communication using mobile communication base station, in combination with hand
Application program built in machine completes the work of the positioning to trapped person in two-dimensional surface.
Summary of the invention
The invention patent proposes a kind of two-dimensional location method for trapped person after shaking, and this method utilizes mobile communication
Base station provides signal covering, while cooperating the related mobile phone application of trapped person's interior of mobile phone, positions to trapped person.
Localization method described in the invention patent includes:
1. providing mobile phone to the mobile phone in region with mobile communication base station having in the trapped region of personnel after the earthquake
Signal of communication.Mobile phone in communication base station coverage area will all access the mobile communication base station.
Further, the mobile communication base station can be the commercial mobile communication base station of China Mobile or China Unicom,
It is also possible to using software radio, i.e., under Linux system, software section utilizes gnuradio and openbts, hardware components
Using usrp or same type software radio peripheral hardware, the mobile communication base station built.
Further, in the case where the communication base station of existing fixation after the earthquake is not available, by locating cellphone
Mobile communication base station used for positioning will be directly connected into.
Further, the region to be rescued should be regular shape region, that is, top view approximation rectangle in region to be rescued,
Or two sides of zone boundary may make up right angle or acute angle, while two side lengths are less than mobile communication base station covering radius.
2. mobile communication base station is moved at another endpoint from an endpoint on the both sides namely broken line that constitute acute angle, transport
The signal strength indication of persistent collection mobile phone is wanted in mobile communication base station during dynamic, and is recorded.
Further, if the mobile communication base station can directly collect the signal strength indication of mobile phone, directly by movement
Communication base station is collected and records to the signal strength indication of mobile phone；If cannot, by the application of trapped person's interior of mobile phone
Program in position fixing process medium time interval sends the short message that content is signal strength to rescue personnel.
The signal strength information of every received mobile phone is analyzed after 3. mobile communication base station moves,
It can find that two peak values can all occur in measurement process in the signal strength of every mobile phone, be done on side locating for it in peak value corresponding position
Vertical line, the intersection points of two vertical lines is by the relative position of locating cellphone.
Further, the relative position by locating cellphone is the location information under two-dimensional surface.
Detailed description of the invention
Fig. 1 shows the simplification figure of localizing environment and process
Specific embodiment
As shown in Figure 1, signal of communication is provided using mobile communication base station the present embodiment provides a kind of, in combination with to be positioned
The application program of interior of mobile phone, come the method positioned to trapped person.Specifically position fixing process includes:
1. firstly, being mentioned with mobile communication base station to the mobile phone in region having in the trapped region of personnel after the earthquake
For mobile phone signal.Mobile phone in communication base station coverage area will all access the mobile communication base station.The mobile communication base station can
To be the commercial mobile communication base station of China Mobile or China Unicom；It is logical to be also possible to the movement built using software radio
Believe base station.Meanwhile region to be rescued should be regular shape region, that is, region top view approximation rectangle or regional edge to be rescued
Two sides on boundary may make up right angle or acute angle, while two side lengths are less than mobile communication base station covering radius.Figure of description exhibition
Show a kind of positioning scene figure of simplification corresponding to the invention patent, while AB with while BC it is vertical, mobile phone icon represents to be positioned in figure
Mobile phone location Q, mobile communication base station P can while AB and while BC on move.
2. secondly, mobile communication base station is moved to another endpoint from an endpoint on the both sides namely broken line that constitute acute angle
Place, mobile communication base station P as shown in figure 1 is moved from point A to point B, then moves to point C.Mobile communication base station is wanted in motion process
The signal strength indication of persistent collection mobile phone, and recorded.If mobile communication base station can directly collect the signal strength indication of mobile phone,
Then directly the signal strength indication of mobile phone is collected and is recorded by mobile communication base station；If cannot, by hand to be rescued
Application program inside machine in position fixing process medium time interval sends the short message that content is signal strength to rescue personnel.
3. finally, being carried out after mobile communication base station moves to the signal strength information of every received mobile phone
Analysis, it is found that two peak values can all occur in measurement process in the signal strength of every mobile phone, do its institute in peak value corresponding position
Vertical line on corresponding mobile communication base station motion profile, the intersection point of two vertical lines is as by locating cellphone on two-dimensional surface
Relative position.By taking the mobile phone Q to be positioned in Fig. 1 as an example, after data-gathering process, the movement line of mobile communication base station
On AB, BC, there is point N and point M, in this two o'clock, the signal strength indication of mobile phone Q is maximum for mobile communication base station.Cross this two o'clock
The vertical line of AB and BC are done respectively, and the intersection point of two vertical lines is position of the mobile phone Q on two-dimensional surface ABC.
The present embodiment can have the improvement in manpower and material resources, while location area compared to the inch-by-inch search mode after earthquake
Relatively wide, holistic approach can have higher utility value.
