Abstract

The system for monitor, control and manage of moving objects in a region is composed of positioner, repeat station and monitor-manage centre. The positioner receives signals from global positioning satellite. After decoding, latitude and longitude data is extracted, which along with intrinsic and state data are coded, modulated and passed to solid emitting unit. After repeat station receives the signals from the unit, the data are sorted, formatted and passed to monitor-manage centre, where the data are decode, descriminated and displayed to position, track and monitor the moving objects.

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, also can 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 a kind of system to the mobile thing supervision in zone, control and management is provided, it has location, Presentation Function, can carry out state recognition, trace and monitor.

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

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, wherein: locating device receives global positioning satellite signal with one second frequency once, through being processed into the longitude and latitude coordinate data, intrinsic fixed data storer, state signal generator will be under clock control, by the time interval or by relay station paging signal triggering mode position signalling and intrinsic data state signal are arranged chronologically, encoded, delivering to the solid transmitter unit after the modulation is sent by antenna; Relay station is arranged on the unmanned data automatic reception on the regional commanding elevation, the processing forward device, by the antenna receiving element, data processing unit, trigger the paging generator, retransmission unit constitutes, this device receives the signal that locating device sends on the mobile object, carry out the data sorting, format is handled, to mail to CSRC administrative center through a frequency main stem with wireless or wired mode orientation through the data of conversion, this center is divided into Data Receiving, signal Processing, the buffer central computer, five parts of 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 transfer that the data pretreatment unit is handled to or input buffer temporary, central computer is handled the information data of the mobile object that directly transfers and the data that buffer takes out; This center to the location of mobile object in order to method down:

(1) present situation by mobile object is differentiated in the decoding and the decoding of signal, the status data and the intrinsic data screening of the object that cruising mobile object, plug are stagnated distinguish, and the information data that will be in the mobile object of special state reaches other dedicated system and further handles, monitors and analyze;

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

(3) the X-Y coordinate data of mobile object is carried 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;

(4) 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.

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, signal forwarding unit 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, the position signal transmitter that the order triggering is installed on automobile is to relay station or directly to control center's emission positioning signal, this mode quantity of information is few, be 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 frequency main stem orientation through the data of conversion.

The data sink at CSRC center receives the signals of vehicles that transmits from the relaying repeater station, and passes toward data 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 at vehicle, will carries out real-time follow-up and monitor and make reaction rapidly and hold instruction;

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