XD-TI298 conventional / cluster alarm system GPS vehicle location technology using GPS and mobile communication technology for vehicle escort. It is particularly suitable for regional vehicle location and monitoring, especially for financial armored car, police cars, ambulances, fire engines and other special vehicles.
XD-TI298 GPS positioning alarm system consists of the following components:
◆ 110 Alarm Command Center
◆ Monitoring and Testing
◆ Financial System Supervision and Control sub-centers
◆ police vehicle command and decision system.
◆ transfer station and the link base stations and other telecommunications network equipment
◆ Car Unit
The system is characterized by:
High reliability, anti-sabotage and anti-jamming performance is good;
Special network-specific, manageable, flexible and convenient network;
The actual public security departments, practical, consistent with the characteristics of actual need.
The system will be GPS, mobile communication technology, GIS and computer technology combined with the data communications on the company's FLASHCALL U.S. TRANSCRYPT digital signaling, PSK modulation, 9 error correction coding, two-way response, random delay retransmission, the bit error rate of one millionth signaling to signaling a strong anti-interference ability, to protect data in case of bad radio environment can be transmitted flawlessly.
The system in Guiyang City and Tianjin's financial armored positioning alarm system has been successfully applied, Guiyang City, the system has reached three years of operation time. Tianjin's financial armored positioning system began testing in 1997 and selection, in June 1998 began the municipal public security bureau has three financial units combined 20 vehicles for small-scale network test and trial operation of the system the thousands of alarms and tracking experiment, were divided two seasons, summer and winter, vehicle equipment, the maximum surface temperature of 84 degrees (Celsius) and lowest -10 degrees (Celsius), and select the overpass, the tunnel under the high-voltage , buildings in poor communication medium was enhanced under the experimental results so that the system has been highly positive. In addition, the communication coverage of dozens of the critical state of alarm and tracking results are not a false negative and false positive.
End of 1998, according to police response alarm systems and management models and experimental conditions on the system structure and software adjustments
1999 年 4 open by month's end and large-scale installation.
