Detailed description of the invention
Below by drawings and Examples, technical scheme is described in further detail.
Technical solution of the present invention is applicable to the people of logistics, finance, tourism, medical treatment, military affairs, prison and some special industry
Member's management and a large amount of asset monitoring location, warehousing management etc..(e.g., first terminal in technical solution of the present invention for having signal
Radiofrequency signal etc.) send or wireless communication module and the mobile terminal device of power module, when being applied to special personnel is entered
During row supervision, first terminal is specifically as follows wearable device；Second terminal for have location (e.g., GPS location etc.) module and
The mobile terminal device of wireless communication module.
The flow chart of the localization method that Fig. 1 provides for the embodiment of the present invention.As it is shown in figure 1, the location of the embodiment of the present invention
Method includes:
Step 101, first terminal sends to the second terminal and identifies signal.
Specifically, send to the second terminal at first terminal and identify before signal, first terminal by host ID to
Second terminal is registered.When first terminal is multiple, carried out to the second terminal by self unique device identification number respectively
Registration, the second terminal presets registered first terminal and the relative distance of the second terminal.First terminal divides according to predetermined period
Do not send to the second terminal and identify signal.
Such as, the second terminal presets relative distance is that radius is the scope of 150 meters with from as the center of circle.So, above model
Enclose interior registered first terminal and send identification signal according to predetermined period to the second terminal.
Wherein, identify that signal includes radiofrequency signal, WIFI signal, Bluetooth signal, infrared signal or wireless communication signals etc..
As a example by radiofrequency signal, the signal transmitting module of first terminal is radio-frequency module, and the radio-frequency module of first terminal is adopted
Sending radiofrequency signal with " active mode " according to predetermined period, the cycle sending signal can be set as required, power supply
Module can take high energy button lithium battery, it is ensured that first terminal can continuous firing.First terminal simple in construction, hardware cost
Low.
It should be noted that according to specific needs, first terminal can also built-in locating module, by position data to other
Terminal is transmitted.Relative distance and transmission cycle can be configured according to specific needs.
Step 102, described second terminal obtains the first range data according to the strength grade of described identification signal.
Specifically, the range sensor of the second terminal built-in, according to identifying the unlike signal strength grade of signal, obtains the
One terminal and the relative distance data of the second terminal.Wherein, the first range data be first terminal and the second terminal relative away from
From.
Such as, signal intensity is divided into multiple rank, when first terminal is with the second terminal as the center of circle, and radius is 30 meters
In the range of time, the second terminal receives the signal intensity one-level of first terminal；When first terminal is at distance the second terminal 30-60 rice
In the range of time, signal intensity is two grades；When first terminal is in the range of distance the second terminal 60-90 rice, signal intensity
It it is three grades；When first terminal is in the range of distance the second terminal 90-120 rice, signal intensity is level Four；When first terminal exists
Time in the range of distance the second terminal 120-150 rice, signal intensity is Pyatyi.
Intensity level signal can be configured according to specific needs, and the second terminal can be come by different signal intensitys
Judge first terminal and the relative distance of the second terminal.
Second terminal according to identifying after signal acquisition the first range data, by the first range data with default relative away from
Compare from data；When the first distance is more than the relative distance preset, the second terminal sends alarm signal.
Such as, default relative distance is 150 meters, if the signal intensity that the second terminal receives first terminal transmission is weaker than
Signal intensity in the range of 150 meters, then explanation first terminal is with the second terminal circle of position heart, and 150 meters is outside the scope of radius,
Second terminal sends alarm signal.
It should be noted that the sensitivity that the second terminal receives the signal that first terminal sends can be entered according to specific needs
Row is arranged.
When carrying out data transmission between first terminal and the second terminal, the data that first terminal sends to the second terminal are passed through
AES is encrypted, so that it is guaranteed that communication process data safety.After the data that second terminal receives, the legitimacy to data
Verify.
Step 103, described second terminal obtains the primary importance data being presently in position.
Specifically, the second terminal positions acquisition by GPS location, microwave positioning or the Big Dipper and is presently in first of position
Put data.
Step 104, described first range data and described primary importance data are sent to server by described second terminal.
Specifically, the second terminal by general packet radio service technology (General Packet Radio Service,
GPRS) described first range data and described primary importance data are sent to server.
GPRS utilizes global system for mobile communications (Global System for Mobile Communication, GSM)
Untapped time division multiple acess (Time Division Multiple Access, TDMA) channel transmission data in network, data pass
Defeated speed is fast.
Step 105, described primary importance data are resolved by described server, obtain the position letter of described second terminal
Breath.
Specifically, primary importance data are resolved by server, obtain longitude and the latitude of the second terminal present position
Angle value.
Step 106, described server, according to the positional information of described second terminal and described first range data, obtains institute
State the positional information of first terminal.
Specifically, the positional information of server by utilizing the second terminal, first terminal and the relative distance of the second terminal, calculate
Obtain the positional information of first terminal.
It addition, after server gets the positional information of first terminal, the second terminal, to first terminal, the second terminal
Change in location is monitored, it is achieved thereby that inquire about on heart platform in the information, monitor and manage terminal.
The localization method that the embodiment of the present invention provides, first terminal obtains multiple without built-in locating module, the second terminal
The position data of first terminal reports server, thus reduces hardware cost, improves data transmission bauds.
The alignment system schematic diagram that Fig. 2 provides for the embodiment of the present invention.As described in Figure, described system includes: first terminal
21, the second terminal 22 and server 23.
First terminal 21 sends to the second terminal 22 and identifies signal；Second terminal 22 is according to identifying that signal strength scale obtains
First range data；Second terminal 22 obtains the primary importance data being presently in position；Second terminal 22 is by the first distance number
It is sent to server 23 according to primary importance data；Primary importance data are resolved by server 23, obtain the second terminal 22
Positional information；Server 23, according to the positional information of the second terminal 22 and the first range data, obtains the position of first terminal 21
Confidence ceases.
