Abstract
The utility model discloses a kind of LBS public transport aided positioning system lost efficacy based on GPS, include MCU, MCU has access to memory module, electric map module, GPS module, LBS module, vehicle dispatching terminal display screen.The utility model adopts multiple location technology to combine, and by judging that gps signal is invalid, then enables assisting navigation mode, reduces system workload, can reach good positioning precision, and the system reform is convenient, without the need to carrying out complicated hardware circuit design.
Description
Technical field
The utility model relates to bus positioning system field, specifically a kind of LBS public transport aided positioning system lost efficacy based on GPS.
Background technology
Along with the fast development of city process, and respond environmental consciousness and whole people's service awareness, public transport has become the preferred traffic instrument of citizens' activities gradually.Whether automatic positioning equipment is intelligent public transportation system chief component now, can accurately locate most important.Existing bus major part is unique locator data with gps signal, and under the driving condition of city, because trees, high building, overpass, tunnel etc. block, gps signal failure conditions happens occasionally, and causes bus cannot effective location, affects the integrality of locator data.For gps signal failure conditions, propose GPS/INS integrated navigation, but there is two problems: (1) high precision INS inertial navigation module involves great expense, and is not suitable for using in bus; (2) when the long-time complete failure of gps signal, inertial navigation module error accumulates in time, and precision can not meet bus positioning requirements.
utility model contentthe purpose of this utility model is to provide a kind of LBS public transport aided positioning system lost efficacy based on GPS, to solve prior art Problems existing.
In order to achieve the above object, the technical scheme that the utility model adopts is:
Based on the LBS public transport aided positioning system that GPS lost efficacy, it is characterized in that: include MCU, the data terminal of MCU has access to memory module, electric map module, and the PORT COM of MCU has access to GPS module, LBS module, and the display port of MCU has access to vehicle dispatching terminal display screen.
The described LBS public transport aided positioning system lost efficacy based on GPS, is characterized in that: the power port of MCU has access to power interface.
The described LBS public transport aided positioning system lost efficacy based on GPS, it is characterized in that: described MCU, memory module, electric map module, GPS module, LBS module, power interface are integrated in same encapsulation, and vehicle dispatching terminal display screen is arranged on package surface.
Under the utility model provides a kind of GPS failure conditions, based on the public transport aided positioning system of LBS.Aided positioning system and public transport vehicle-mounted dispatch terminal integrated after, can when signal stop causes gps signal to lose efficacy, automatic employing LBS locator meams, obtain bus current location information, this information is mated with mapping module, find the position coordinates of bus on map, to carry out the effective location of public transit vehicle real time position.
The utility model adopts multiple location technology to combine, and by judging that gps signal is invalid, then enables assisting navigation mode, reduces system workload; Further, under the driving condition of city, base station number is many, adopts LBS localization method, can reach good positioning precision, not need to increase other aiding sensors, can effectively control cost; Meanwhile, public transport traffic route is fixed, and with this in conjunction with electric map module, carries out traffic route demarcation in advance, effectively can improve positioning precision; Disposal system can with original public transport vehicle-mounted dispatch terminal and use, and the system reform is convenient, without the need to carrying out complicated hardware circuit design.
Accompanying drawing explanation
Fig. 1 is the utility model structured flowchart.
Embodiment
Shown in Figure 1, based on the LBS public transport aided positioning system that GPS lost efficacy, include MCU1, the data terminal of MCU1 has access to memory module 5, electric map module 6, the PORT COM of MCU1 has access to GPS module 3, the display port of LBS module 4, MCU1 has access to vehicle dispatching terminal display screen 7.
The power port of MCU1 has access to power interface 2.
MCU1, memory module 5, electric map module 6, GPS module 3, LBS module 4, power interface 2 are integrated in same encapsulation, and vehicle dispatching terminal display screen 7 is arranged on package surface.
MCU1 communicates with GPS module 3, LBS module 4 and vehicle dispatching terminal display screen 7.Principle of work is: after system electrification, described MCU1 prioritizing selection GPS locator meams, and continual reception also detects the signal that GPS module 3 sends over automatically; If GPS module 3 invalidating signal detected, then automatically switch to the work of LBS locator meams; Meanwhile, system possesses the function of manual switchover locator meams, arranges by car-mounted terminal scheduling display screen 7 human-computer interaction interface, to adapt to more environments for use; After systematic evaluation to LBS locator meams, bus current location is obtained by LBS module 4, described LBS module 4 adopts the GPRS module of advanced technology, the built-in LBS agreement of described GPRS module, current location information is obtained on the one hand by mobile base station, final position information is uploaded to bus dispatching center, to monitor on the other hand; Then data and electric map module 6 are matched, described electric map module 6 is controlled by MCU1, can public bus network number set by current vehicle-mounted dispatch terminal, electronic chart demarcates bus travel route in advance, real-time for public transit vehicle anchor point and the traffic route of demarcating in advance are matched, to improve positioning precision; Meanwhile, system possesses the function whether unrestricted choice demarcates traffic route in advance, can be arranged by the human-computer interaction interface of vehicle dispatching terminal display screen 7; After finally obtaining effective location data, vehicle dispatching terminal display screen 7 shows.
