Embodiment 1

[0028] The method for using the anti-interference vehicle communication system of this embodiment includes the following steps:

[0029] Step 1: Connect the filter and antenna to the communication host respectively;

[0030] Step 2: Set the timing module, set the time for active frequency switching to 30 seconds, and set the time for passive frequency switching to 2 seconds;

[0031] Step 3: After starting the communication host, the timing module starts timing, and the frequency conversion module performs input / output frequency conversion every 30 seconds;

[0032] Step 4: Actively carry out weak signal interference, and the communication signal has not been lost.

Embodiment 2

[0034] The method for using the anti-interference vehicle communication system of this embodiment includes the following steps:

[0035] Step 1: Connect the filter and antenna to the communication host respectively;

[0036] Step 2: Set the timing module, set the time for active frequency switching to 30 seconds, and set the time for passive frequency switching to 2 seconds;

[0037] Step 3: After starting the communication host, the timing module starts timing, and the frequency conversion module performs input / output frequency conversion every 30 seconds;

[0038] Step 4: Actively carry out strong signal interference, loss of communication signal is detected, the timing module enters the time mode of passive switching frequency, after 2 seconds, the frequency conversion module performs input / output frequency conversion, stops signal interference, and re-detects communication input / output Frequency, re-enter the active switching frequency mode.

Embodiment 3

[0040] The method for using the anti-interference vehicle communication system of this embodiment includes the following steps:

[0041] Step 1: Connect the filter and antenna to the communication host respectively;

[0042] Step 2: Set the timing module, set the time for active frequency switching to 30 seconds, and set the time for passive frequency switching to 2 seconds;

[0043] Step 3: After starting the communication host, the timing module starts timing, and the frequency conversion module performs input / output frequency conversion every 30 seconds;

[0044] Step 4: Actively carry out strong signal interference, the communication signal is lost and detected, the timing module enters the time mode of passive switching frequency, after 2 seconds, the frequency conversion module performs input / output frequency conversion, and continues to interfere, and the communication input / output has not been detected Frequency, the alarm module sends out an alarm, the electric modul...

Abstract

The invention discloses an anti-interference vehicle-mounted communication system. The system comprises a central processor, a communication module, a positioning module, a signal transceiver, a signal converter, a timing module, a frequency conversion module, an alarm module and a power supply module. The central processor, the communication module, the positioning module, the signal transceiver,the signal converter, the timing module, the frequency conversion module, the alarm module and the power supply module are all arranged in the communication host. According to the present invention,the structure is reasonable, and by arranging the timing module and the frequency conversion module, the automatic frequency changing and switching are achieved after the timing is performed, such that the interference probability is substantially reduced.

Description

technical field [0001] The invention relates to the technical field of anti-jamming vehicle communication systems, in particular to an anti-jamming vehicle communication system and method. Background technique [0002] The so-called in-vehicle communication system is based on the development of intelligent transportation system and sensor network technology, and applies advanced wireless communication technology to vehicles to realize the means of highly informatized and intelligent traffic. The broad definition of in-vehicle communication system refers to the The mobile communication system on the vehicle, the vehicle communication system uses the vehicle as the carrier, and can transmit wireless signals with the movement of the vehicle. The in-vehicle communication system can solve communication problems encountered during driving, making driving safer and more convenient. [0003] Traditional vehicle communication is particularly susceptible to interference during travel...
