Car GPS system

　　1 GPS processor (GPSPU)

　　It is an information system that is installed in the vehicle to continuously calculate the location of the vehicle. It has the characteristics of small size, not smooth surface, and light weight. It can communicate with the command center and can also be used as an independent data recorder (with a black box) function.

　　The constituent component of GPSPU:

　　High -quality GPS receiver; a miniature processor; black box memory; communication modem; interface provided for peripheral devices; forwarder (optional) for individuals (optional); differential receivers (optional).

　　It is an internal GPS receiver for the design of mobile objects. It can accept Channel 12 and sensitive RF front -end. The scientific software computing method makes the device under harsh environment. For example, there are tall buildings, big trees, etc. There are also good performance. Can quickly position and get the signal quickly after the signal is lost.

　　2 miniature processor

　　There is a processing chip for the internal operating system in the GPSPU box. It reads position output from the GPS receiver and stores the information of the current format into the mainboard's memory (or the optional internal modem will transmit the data to the control center). Most functions of the system GPSPU are provided by their software, and the system can maximize the compatibility of the user's system. It can control the input/output and surrounding additional devices. Most micro -processors' functions are controlled by the control center.

　　3 Black Box (Data Record)

　　GPSPU sustainable records of the location information of the vehicle and stored in the main board's memory. The frequency of data records and records can be set to meet different needs. Because the fixed memory is a curing memory, even if the GPSPU system is permanently without electricity. It can also protect the data well. The location information recorded in GPSPU memory generally includes the identity identification number, date, time, latitude, longitude, speed, GPS status of the transportation of the transportation.

　　4 communication options

　　The VTS system uses the most advanced technology today, which can be compatible with all current standard communication networks. When a communication connection device (such as RF, GSM modem) is required for remote monitoring and operation, any type of standard communication modem can be used. Most of the communication modem can be loaded on the GPSPU system.

　　5 The interface of the surrounding device

　　The standard GPSPU has 3 optical resistance interfaces and 4 open electronic output ports. They can be used to receive or return electronic signals to other devices, such as door locks, alarms, sensors, and so on. At the same time, two serial communication and one bus interface are also provided for connection to mobile digital terminals, displays/keyboards, differential receivers, alarm systems, transportation control devices, etc.
