4, mode is flexible, and is easy to use
Employed running fix radio station has several working ways in this method, as shows this machine location locating information; Local locating information is sent to Surveillance center and Surveillance center carries out function of voice communication etc.Sending locating information to Surveillance center need not special operational, and the running fix radio station can require to send automatically or finish automatically in the moment of conversation according to control and monitor console.
5, graphic presentation, visual in image
Adopted advanced electronic map technique in this method, monitored moving target is shown on the computer electronic map display real-time dynamicly.Also can carry out translation, amplify, dwindle electronic chart, etc. operation, very convenient directly perceived.
Describe in detail below.
The following composition of the equipment of this method:
1, running fix radio station, some of integrated encode devices (to call transfer table in the following text);
2, transfer transmitting-receiving some in radio station (to call terminal in the following text);
3, center monitoring radio station, one one of integrated encode device (to call zone center in the following text);
4, one one in center monitoring computer (to call monitoring computer in the following text);
5, central figure shows some in computer (to call the figure computer in the following text);
Use in the system of this method each to move object and all have one one of transfer table, every radio station all has a fixing numbering, GPS locating device (GPS OEM circuit board) is equipped with in transfer table inside, start back, radio station data acquisition circuit is regularly gathered the position data that locating device is sent, and handles respectively by following four kinds of different situations:
1,, then the position data that the collects method for expressing with longitude and latitude is presented on this machine LCD screen if this machine is in from showing unfolding mode.
2, if this machine is subjected to Surveillance center's query call, promptly Surveillance center requires passback one deuterzooid transfer table current location data, and then this transfer table returns a current location data automatically.
3,, then regularly send the position data of this transfer table at interval to Surveillance center by system's official hour if this transfer table is in monitored state.
4, if this transfer table is in talking state, then the user whenever presses a talk key and passes position data back Surveillance center automatically.
Urgent call (or claiming to report to the police) button also is housed on transfer table, can be installed in the shelter for this button of vehicle-mounted transfer table, when the platform master runs into emergency, press this key, transfer table meeting urgent call Surveillance center finishes the warning help function.
As transfer table distance detection center (more than 30KM) far away, in the time of can't directly communicating by letter, or during owing to extreme terrain generation communication blind district, must in system, set up terminal with Surveillance center, terminal is differentiated the signal of receiving and is transmitted.
After control and monitor console receives the call signal of transfer table, the numbering and the position data that identify transfer table through decoding unit decodes send monitoring computer and graphics process computer to by interface circuit, the call contents that shows transfer table on the monitoring computer with character mode, and after the graphic presentation computer receives the position signalling of mobile object, promptly on electronic chart, demonstrate the transfer table position in the icon mode.
If urgent call (warning) information of transfer table is received by Surveillance center, then return an instruction immediately and give this transfer table, the instruction of passback has two layers of meaning: at first be the alerting signal that affirmation Surveillance center has received this transfer table; Next is that transfer table is set as monitored state, determine according to the quantity of the mobile object of the current tracking of Surveillance center and the rank of alarm station by the system call software in the monitoring computer to the value that Surveillance center transmits its position data time interval according to certain time interval, transfer table returns data according to Surveillance center's designated time intervals after entering monitored state automatically, need not any manual intervention.Simultaneously, the system manager also can access the background information of this warning in moving in the database of Surveillance center, as platform master name, and ID (identity number) card No., telephone number can be taked further emergency measure by these information notice relevant department or personnel.
