Abstract
The invention discloses a monitoring and dispatching system and a method of an LBS vehicle. The method comprises the following steps: a vehicle-mounted locator receives locating data of a satellite and calculates own geographical position coordinates; an intelligent wireless communication terminal transmits the coordinate data and the state information request to a CDMA base station which furtherforwards the information to a monitoring center through a CDMA exchanger and matches the information with GIS, compresses video data inside and outside the vehicle collected by video monitoring equipment through a video compression coding module, and remotely transmits the compressed video data to each command center through EVDO wireless network. The invention can transmit multi-path clear coherent videos, not only single static images, and can realize wireless uploading and wireless watching.
Description
Technical field
The invention belongs to the information automation field, relate in particular to supervisory system and the method for utilizing LBS location-based service positioned vehicle.
Background technology
At present, though existing vehicle monitoring and dispatching system is improving car operation efficient, is strengthening the vehicle driving security and solve on the road traffic problem and brought into play important effect on the market, but but exist a lot significantly not enough, higher as the construction operation expense, the monitoring limited coverage area, control real-time is poor, and system extension is difficult in maintenance, and scheduling feature lacks aid decision making support etc.These deficiencies have limited the application and the range of application of vehicle monitoring and dispatching system, make the vehicle monitoring and dispatching system be difficult to move towards the publicization.With the be applied as example of vehicle monitoring and dispatching system in transportation industry:
Existing vehicle monitoring and dispatching system mostly carries out real-time video monitoring based on CDMA or GPRS on the market, and transfer rate is low, and the video monitoring picture effect is not good.
Summary of the invention
The technical problem to be solved in the present invention is the defective that exists at prior art, and the LBS vehicle monitoring and dispatching system and method for a kind of EVDO of utilization mobile communication technology and WebGIS technique construction is provided.
LBS vehicle monitoring and dispatching system, it is characterized in that all being provided with on the vehicle video monitoring equipment, gps receiver, video compression coding module, single-chip microcomputer, voice module and intelligent wireless communication terminal, also comprise cdma base station and Surveillance center, wherein connect the input end of intelligent wireless communication terminal after the output terminal of the video monitoring equipment serial connection video compression coding module, connect the input end of voice module and intelligent wireless communication terminal behind the output terminal serial connection single-chip microcomputer of gps receiver respectively, the intelligent wireless communication terminal is by cdma base station and Surveillance center's wireless connections.
The method of described LBS vehicle monitoring and dispatching system is characterized in that may further comprise the steps:
(1) locator data that adopts gps receiver to accept satellite obtains positional information and status information;
(2) described positional information of step (1) and the site location coordinate that is stored in the single-chip microcomputer are compared,, report site information by voice module at automobile turnover website; And the described status information of step (1) is transmitted to cdma base station through the intelligent wireless communication terminal;
(3) be transmitted into cdma base station by the intelligent wireless communication terminal again after the analog image process video compression coding module compression with the video monitoring equipment collection;
(4) described cdma base station is forwarded to Surveillance center by the CDMA switch with described status information of step (1) and the described analog image information of step (3);
(5) described status information of step (4) and the GIS of system are complementary, and the analog image information decoding is realized vehicle monitoring and dispatching.
Advantage of the present invention and effect are: automatic broadcasting, can support data communication service preferably, and communication quality is reliable and stable.Can transmit the video that multichannel links up clearly, rather than the static picture of single width.Personnel in Surveillance center just can see timely video by network like this; The leader also can watch video by surfing Internet with cell phone, in time instructs work on the spot whenever and wherever possible, as handling emergency incident, commander's rescue and relief work etc.
