With the extensive use of technology of Internet of things, single GPS positioning mode has been difficult to meet the requirement of consecutive tracking, such as exists
Indoor, signal, which is blocked area, causes receiver range error to increase and can not obtain correct positioning result, or even can not be into
Row positioning.In order to overcome the weakness of GPS system, need to be combined using the localization method of GPS and other non-line-of-sight vectors come
Realize weak signal or without the positioning under navigation signal environment.
RFID and WSN is most important identification technology in Internet of Things, is respectively applied to different occasions, each advantageous but each
From there is its shortcoming, territory is limited its application, if it is possible to be complementary to one another, then can be used as signal and blocked area
Auxiliary positioning mode.
(3) summary of the invention
That in order to compensate for the shortcomings of the prior art, the present invention provides a kind of network coverages is wide, operating cost is low, positioning accuracy
The high indoor and outdoor positioning system with automatic switching function.
The present invention is achieved through the following technical solutions:
A kind of indoor and outdoor positioning system with automatic switching function, including the RFID label tag and RFID read-write being correspondingly arranged
Device, it is characterised in that: be integrated with microcontroller in the RFID label tag and be embedded in GPS module, wireless communication module and GSM mould
Block, microcontroller and GPS module, wireless communication module, gsm module, power module and Flash RAM are interconnected, channel radio
Antenna is communicated in letter module.
The present invention microcontroller is integrated in single RFID label tag and be embedded in GPS module, wireless communication module,
Gsm module can be realized the two-way communication with reader, and can be realized the automatic switchover of indoor and outdoor positioning, to expand
Big orientation range, improves positioning accuracy, and reduce manual intervention, has saved cost.
More excellent technical solution of the invention are as follows:
The RFID reader includes RS232 interface and microcontroller, microcontroller and wireless communication module, gsm module,
Power module, Flash RAM are interconnected, and part RFID reader has the function of gateway concurrently, to realize active reader
With the two-way communication of active tag.
The RFID label tag and RFID reader work in 2.4G ISM band, in the covering model of wireless sensor network
It encloses, the indoor accurate position more than 1500 meters can be realized by multi-hop mode, due to being integrated with gsm module, there is Global Link
Telecommunication function, when in the coverage area of wireless sensor, capable of also not obtaining location information remotely.
When RFID label tag is in the coverage area of wireless sensor network, GPS and gsm module not will start, by RFID
Reader calculates location information according to RSSI value and is transferred to control computer by multi-hop mode；When RFID label tag is beyond covering
When range, starting GPS and gsm communication mode are automatically switched to reduce the consumption of power supply and extends the service life of label.
The system has many advantages, such as network coverage is wide, networking flexibility is quick, operating cost is low, reliability and positioning accuracy are high, benefit
The positioning functions such as indoor and outdoor, long-range are realized with it with can be convenient.
Since label is battery power supply, automatic switchover algorithm is devised, realizes automatic conversion operating mode and periodic wakeup
Mechanism minimizes signal processing time, reduces electric quantity consumption, and extend label uses the time.
The mode that the RFID reader wirelessly forms multi-hop ad hoc net connects, and constructs RFID reader
Network is in communication with each other, co-ordination, multipoint acquisition and transmission, realizes the information efficiently, rapidly read on label, while letter
The process of networking is changed, and data, the number of tags being collected into each RFID reader can have been uploaded by the topological network of layering
According to according to the positioning of the ID, RSSI value or GPS position information realization people or the article that receive, thus fast by way of multi-hop
It is transferred on control computer fastly.
The present invention utilizes the combination of GPS, RFID, GSM and WSN, has automatic switching function, realizes the people of indoor and outdoor complexity
Member's positioning, monitoring and tracking task, and target object is accurately searched, realize real-time positioning and monitoring pipe to personnel and article
Reason.

The present invention will be further described below with reference to the drawings.
Fig. 1 is the structural schematic diagram of RFID label tag of the present invention；
Fig. 2 is the structural schematic diagram of RFID reader of the present invention；
Fig. 3 is automatic switching procedure schematic diagram of the present invention.
In figure, 1 microcontroller, 2 GPS modules, 3 wireless communication modules, 4 gsm modules, 5 power modules, 6 Flash
RAM, 7 antennas.
(5) specific embodiment
Attached drawing is a kind of specific embodiment of the invention.The embodiment includes the RFID label tag and RFID read-write being correspondingly arranged
Device is integrated with microcontroller 1 in the RFID label tag and is embedded in GPS module 2, wireless communication module 3 and gsm module 4, micro-control
Device 1 processed is interconnected with GPS module 2, wireless communication module 3, gsm module 4, power module 5 and Flash RAM6, wireless communication
Antenna 7 is communicated in module 3；The RFID reader includes RS232 interface and microcontroller 1, microcontroller 1 and wireless communication
Module 3, gsm module 4, power module 5, Flash RAM6 are interconnected；The RFID label tag and RFID reader work in
2.4G ISM band；The mode that the RFID reader wirelessly forms multi-hop ad hoc net connects, and constructs RFID
Reader network.
When carrying the location information of people or object of label can be received by the GPS receiver in label, label master
Dynamic starting TTF(card is first made a speech) agreement, location information is periodically sent to RFID reader, RFID reader will receive
Location information host is sent to by RS232 interface；Under environment indoors or GPS receiver does not receive location information
When, in wireless sensor network coverage area, GPS receiver will in a dormant state, and label is automatically switched to RTF(read-write
Device is first made a speech) agreement, wait the inquiry signal of RFID reader, when label receives inquiry signal, label by the ID of itself and
RSSI value is sent to RFID reader, it means that label is unless receive inquiry signal, and otherwise the most of the time is in suspend mode shape
State does not send data, can save a large amount of energy in this way.Reading device position is relatively fixed, can find out in advance, arranges in advance
Reader the people for carrying label or the location information of object are calculated using RSSI value, it is fixed that Centimeter Level can be obtained in several milliseconds
