Specific embodiment

In the embodiment shown in fig. 1, the utility model includes main receiver 1 and companion receiver 5, wherein 1 electricity of main receiver Property connection signal radio-frequency module 2 and baseband chip 3 is electrically connected by signal RF module 2, companion receiver 5, which is electrically connected, to be adjusted Conversion tuner 6 and by fm tuner 6 be electrically connected RDS chip 7, RDS chip 7 or baseband chip 3 are electrically connected control Coremaking piece 4, control chip 4 are also electrically connected the first storage card 8, and interface module 9 passes through data line electrical property phase with control chip 4 Even, the second storage card 11 is electrical connected by detection module 10 and control chip 4, and the second storage card 11 is also electric with baseband chip 3 Property be connected；The main receiver 1 or companion receiver 5 is specifically GPS ceramic antenna；The signal RF module 2 is specifically GPS radio frequency circuit, the baseband chip 3 are specifically GPS baseband processor；The fm tuner 6 is specifically FM frequency modulation Device；The control chip 4 is specifically STC89C51 single-chip microcontroller；The interface module 9 is specifically that RS232 interface drives TFT Liquid crystal display；The detection module 10 is specifically detecting circuit.

In common specific implementation, main receiver 1 is sent to the signal RF module to receive positioning signal 2, it is amplified by the signal RF module 2, is converted and digitized processing, the baseband chip 3 is resent to, through the base band After chip 3 carries out spread spectrum and synchronization process to it, it is resent to the control chip 4, by the control chip 4 to the positioning signal Positioning coordinate computation is carried out, which is sent to the fm tuner then to receive frequency modulated subcarrier signal 6, modulation process is amplified and solved to it by the fm tuner 6, and by the centre frequency demodulated be 57KHz, bandwidth is The frequency modulated subcarrier signal for the RDS that 4KHz and data transmission rate are 1200bps, is sent to the RDS chip 7, through the preprocessor 7 After synchronizing of the block data processing in the frequency modulated subcarrier signal of the RDS, it is resent to the control chip 4, by this Block data in the frequency modulated subcarrier signal of the RDS is parsed into TMC data (being not limited only to TMC data) by control chip 4, and Institute's operation and the positioning coordinate data and TMC data transmission for parsing gone out simultaneously by the interface module 9, for its phase The electronic device identification of connection and the situation for analyzing current location.

In specific implementation, main receiver 1 is sent to the signal RF module 2 to receive positioning signal, by this Signal RF module 2 amplifies it, converts and digitized processing, is resent to the baseband chip 3, baseband chip 3 will frequency Secondary higher bit data segment storage is to the second storage card 11, before control chip 4 carries out positioning coordinate computation to the positioning signal By detection module 10 identify current positioning signal whether with the second storage card 11 storage bit data have it is larger coincide, knowing In not, it is all reduced to wave band data particular by the bit data for storing current positioning signal and the second storage card 11, is known Then the high wave band of other Gaussian Profile similarity controls chip 4 and directly chooses a default segment as larger identical data Bit data be inserted into current positioning signal, the size of default segment can be adjusted according to practical application, in this way, Default segment can directly replace subsequent one section of positioning signal to be treated, thus reduce the calculating time of control chip 4, One location data can be sent to interface module 9 earlier by control chip 4 can greatly improve location efficiency.

As known by the technical knowledge, the utility model can pass through other essence without departing from its spirit or the reality of essential feature Scheme is applied to realize.Embodiment disclosed above, in all respects are merely illustrative, not the only.It is all Change within the scope of the invention or equivalents of the invention is included in the utility model.
