Description

Regional moving article monitoring and controlling managing system

The present invention relates to a kind of method and apparatus that mobile object (as vehicle) is monitored, controls and manages.

At present, GPS (being called for short GPS) has been applied to aviation, navigation, mapping, each field such as geologic prospecting and traffic department, this system depends on satellite constantly to send navigation and position signalling earthward, because satellite orbit is very accurate, its time accuracy also reaches microsecond, therefore, as long as receive three satellite-signals, just can obtain precision at 30 meters with interior locator data, can also obtain elevation information if receive four satellite-signals, this system can provide ground received vector (aircraft, ship, vehicle and pedestrian) translational speed, distance from certain known point, data such as orientation, but this cover system limitation is: no position location Presentation Function, can't discern various states, follow the tracks of and monitor, thereby be difficult for promoting.

The objective of the invention is to overcome the deficiency of above-mentioned known technology, thereby provide a kind of system to the mobile thing supervision in zone, control and management, it has accurate localization, Presentation Function more, can carry out state recognition, trace and monitor, and on macroscopic view mobile object is managed.

The objective of the invention is to realize by following measure:

One, this system is made up of three parts: locating device, relay station and CSRC administrative center, locating device is placed in the mobile object, be made of three unit: GPS receives processing unit, intrinsic fixed data unit and solid transmitter unit, it is characterized in that: the GPS in the locating device receives processing unit and receives global positioning satellite signal with one second frequency once, through being processed into the latitude and longitude coordinates data, being placed in the signal storage of intrinsic fixed data unit and storing, simultaneously by time interval that clock produced through decoding, sending into solid transmitter unit modulation back after coding is discerned is sent by antenna by the solid transmitter unit.Relay station is arranged on the automatic reception of unmanned data, the processing forward device on the regional commanding elevation.Constitute by antenna receiving element, retransmission unit, be responsible for the connection of the communication link between transfer control center and the ride, transmit uplink and downlink signals.This device receives the signal that locating device sends on the mobile object, carries out data sorting, format processing, will mail to CSRC administrative center with wireless or wired mode after modulating through the data of conversion.This center is divided into data receiving system, signal processing system, buffer, central computer, Geographic Information System GIS and communication and command system.Data receiving system receives relay station and transmits the mobile object signal data of coming, and transfers that signal processing system is handled or input buffer temporary to, and central computer is handled the information data of the mobile object that directly transfers and the data that buffer takes out; This center is to the following step method of the locating and displaying of mobile object:

A, present situation by mobile object is differentiated in the decoding and the decoding of signal, the status data and the intrinsic data screening of cruising mobile object, unusual object are distinguished, and the information data that will be in the mobile object of special state is further handled, is monitored and analyzes;

B, convert the position signalling of mobile object to the X-Y coordinate data;

C, with the X-Y coordinate system data of mobile object carry out projective transformation and scale change make it with geography information in the mileage chart stack of picture library, generating has the scatter diagram of digital geographical background and imports display unit and carry out large screen display, figure and data output;

D, when recognizing the mobile object abnormal state, change data over to secondary computer and handle:

A. under mobile object loss situation, carry out real-time follow-up and make command adapted thereto rapidly;

B. break down, find rapidly during accident its number and affiliated relation thereof at mobile object, and show the position of fault body.

Two, the present invention compared with prior art has following advantage:

(1) method that adopts GPS and GIS to combine can be measured the position of intending the control object at any time.

(2) property everywhere: in the coverage of setting, not influenced by landform, buildings, all kinds of mobile objects are implemented the location.

(3) have Autoattendant, high accuracy, safety and stability.

(4) contain much information, adopt digital form, be easy to utilize and handle.

Below in conjunction with drawings and Examples the present invention is further described:

Fig. 1 is a locating device principle of work block diagram of the present invention

Fig. 2 is a relay station principle of work block diagram of the present invention

Fig. 3 is a central control management central task schematic diagram

Fig. 4 is a central control management central task process flow diagram

Fig. 1-Fig. 4 is one embodiment of the present of invention, is used for urban traffic control, and this system is made up of following three parts: vehicle locating unit, relay station and CSRC administrative center.

The vehicle location data acquisition has dual mode: directly emission and " paging " formula triggering collection mode, directly radiation pattern is that the GPS receiver is contained on the vehicle, with per second frequency receiving satellite positioning signals once, be converted into after the processing through, the latitude coordinate data, encoded modulation back is launched by antenna, this mode system complex, contain much information, what present embodiment adopted is " paging " formula (see figure 1): launch one group of trigger pip by sequence number scanning when needed by control center or relay station, trigger the position signal transmitter that on automobile, installs successively to relay station or directly to control center's emission positioning signal, this mode quantity of information is few, is convenient to Treatment Analysis.

Relay station is contained on the commanding elevation, city, is used to receive the signal that the ground run vehicle sends, and signal is carried out data sorting, format processing, will mail to the CSRC center by certain channel orientation through the data of conversion.

The data sink at CSRC center receives the signals of vehicles that transmits from the relay station repeater station, and passes toward signal processing unit and further handle or import the working storage buffer memory, and its job step is as follows:

(1) present situation by vehicle is differentiated in the decoding and the decoding of signal, cruising or stagnant vehicle status data and the license number data screening of plug are distinguished, and position data is for further processing, the signals of vehicles that will be in special state reaches other dedicated system and further handles supervision and analysis;

(2) position signalling with vehicle converts the X-Y coordinate data to;

(3) with the X-Y coordinate data of vehicle according to the requirement that shows carry out projective transformation and scale change make it with picture library in the stack of different proportion chi communication chart, generating has the scatter diagram of digital geographical background and imports display unit and carry out large screen display and data output;

When recognizing vehicle-state when unusual, change data over to secondary computer system special disposal separately:

1) is held as a hostage or during stolen situation, will carries out real-time follow-up and monitor and make rapidly the anti-hijacking instruction at vehicle;

2) under vehicle breaks down even can inquire vehicle rapidly during traffic accident, concern, and show the position of fault car so that make necessary reaction.
