Description
Technical field
The present invention relates to data communication field, the method and master base station of especially a kind of label of positioning in the wireless network.
Background technology
Ultra wide band (Ultra Wideband, abbreviation UWB) is a kind of no-load communication techniques, utilizes nanosecond to Microsecond grade
Non-sinusoidal waveform burst pulse transmits data, because ultra-broadband signal in itself has low in energy consumption, safe, multi-path resolved ability strong
Feature, recent domestic starts with UWB to do high accuracy positioning.
TOA (Time of Arrival) location algorithm, is a kind of algorithm positioned using time of arrival (toa),
It is one of GSM foundation location algorithm, is easily obtained with positional parameter, the features such as positioning precision is higher.TOA is calculated
The system architecture of method is as shown in figure 1, the framework is made up of 3 parts：Label, base station (including base station 1, base station 2, base station 3), clothes
Business device.
During label is ultra-wideband positioning system, the appliance arrangement being positioned, it can be mobile.General form can be with
It is work board, wrist strap bracelet is fixed on safety cap first-class.The radiofrequency signal emitted from label is exactly UWB ultra-broadband signals, mark
Label have been internally integrated power module, motion sensor, MCU (Microcontroller Unit micro-control units) module, UWB and penetrated
Frequency module.When label is in non-sent and receives working condition, low-power sleep state is typically in, is slept in low-power consumption
The duty ratio of time of dormancy state is bigger, and the average power consumption of label is lower, and endurance is stronger.Every time used in positioning label
Time is shorter, and the utilization rate of resource is higher, thus the more time be in low power consumpting state, the capacity of simultaneity factor is bigger.
Base station is the fixing point in ultra-wideband positioning system, and it must be that fixed position is installed.Base station is mainly used to reality
Now with the ranging of label, and upload ID, relative distance value, RSSI (the Received Signal Strength of label
Indication receive signal intensity indicate) etc. information to server.Inside of base station is integrated with power module, MCU
(Microcontroller Unit micro-control units) module, ethernet module, (WIreless-Fidelity is wirelessly protected Wi-Fi
Very) module.
Server is an information aggregate processing unit, usually one computer.It has gathered all base stations and has uploaded
Each label information, then carry out storage processing, counting statistics.The known coordinate and each base station and label of each base station are utilized simultaneously
The range data of ranging, the elements of a fix of label is obtained by triangle polyester fibre and least square method, and show on server interface
Show to come.
The method for doing high accuracy positioning using UWB in the prior art is as follows：
Step one：Label sends broadcast message and explored；
Step 2：Base station receives broadcast message and the label information in broadcast message is uploaded into server；
Step 3：Server collects label information and selects Base Station Identification, and Base Station Identification is sent into label；
Step 4：Label carries out ranging according to Base Station Identification base station corresponding with Base Station Identification；
Step 5：Base station is by distance measurement result upload server；
Step 6：Server is resolved according to base station coordinates and range data to tag coordinate, obtains the position of label.
It can be seen that, in the prior art, it can just start the operation of ranging after label receives Base Station Identification, if received over time,
This time positioning just have failed, all operations before wasting.So what Base Station Identification can be stablized, quickly it is communicated to
Label, is directly connected to capacity, the power consumption of label of system, and how to ensure on this basis in real system is installed,
Reducing cost of layout and arrangement difficulty also turns into urgent problem to be solved.
