Abstract
The invention relates to a traffic accident automatic sound detection and alarm terminal which consists of an automatic sound detection device, an alarm device and a power supply module. The automatic sound detection device is used for collecting and inputting sound signals, converting, processing and distinguishing sound signals and sending out an alarm signal when set conditions are met; the alarm device is used for receiving alarm information sent by the automatic sound detection device and sending the alarm signal to a remote server through wireless communication after processing the alarm information; and the power module is used for providing a power source, wherein signal output end of the automatic sound detection device is connected with the signal input end of the alarm device, and the output end of the power module is respectively connected with the power output ends of the automatic sound detection device and the alarm device. The invention can directly and accurately obtain the alarm information of a traffic accident and can effectively obtain the spot of the traffic accident.
Description
Technical field
The present invention relates to traffic hazard and detect automatically and warning device, particularly relate to and utilize voice signal to carry out the device usefulness that traffic hazard detects and reports to the police.
Background technology
With respect to the development of automatic event detection technique, the research that major traffic accidents are detected comparatively lags behind.Traditional traffic events pick-up unit mainly is divided into the vehicle equipment based on magnetic frequency signal, based on the spectroscopic signal vehicle equipment with based on the vision signal vehicle equipment.But various sensors comprise camera, ultrasound wave, microwave are used to detect traffic events, mainly are conceived to macroscopical road traffic stream information such as vehicle flow, vehicle occupation rate, vehicle density etc., detection for this microphenomenon of traffic hazard is indirect, poor effect.Then there is eyewitness's restriction on the scene in the mode that present stage the most effectively dials the police emergency number, and the spot is difficult to determine that warning message is screened difficulty.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, designed and developed out a kind of automatic sound detection of traffic hazard and alarm terminal that can directly accurately obtain the traffic hazard warning message.
The present invention is achieved by the following technical solutions:
Automatic sound detection of traffic hazard and alarm terminal by being used for sound signal collecting input, and conversion, being handled and are differentiated voice signal, are meeting the automatic sound detection device that sends alerting signal when imposing a condition; Be used to receive the warning message that automatic sound detection device sends, and will by wireless telecommunications alerting signal be sent to the warning device of remote server after the alarm information processing; Provide the power module of power supply to form with being used to; The signal output part of described automatic sound detection device is connected with the warning device signal input part; Power module outlet is connected with the power output end of automatic sound detection device and warning device respectively.
Automatic sound detection of traffic hazard and alarm terminal, described automatic sound detection device is by the acoustic input dephonoprojectoscope that is used to gather the external environment acoustical signal; Be used for acoustical signal is converted to the speech processing module of specific format digital signal; Be used for the digital signal through conversion of processed voice processing module transmission, calculate judged result, the DSP module of the concurrent alert signal of delivering newspaper; And be used to store data and the curing code data that needs are handled, and, the DSP module arithmetic forms for providing the memory module of interim storage space; Described acoustic input dephonoprojectoscope signal output part is connected with the speech processing module signal input part; The speech processing module signal output part is connected with DSP module by signal input end; The DSP module is connected with memory module is interactive.
Automatic sound detection of traffic hazard and alarm terminal, described warning device is by being used to receive alerting signal that automatic sound detection device sends and the primary controller of handling this signal; Be used for alerting signal is radioed to the wireless communication module of remote server; The signal output part of described primary controller is connected with the wireless communication module signal input part.
Automatic sound detection of traffic hazard and alarm terminal, described acoustic input dephonoprojectoscope are microphone.
Automatic sound detection of traffic hazard and alarm terminal, described wireless communication module is by gps receiver, GPRS module and GPRS antenna; Gps receiver is connected with the GPRS antenna is interactive respectively with the GPRS module.
The present invention obtains car crass sound by automatic sound detection device, and car crass sound effectively distinguished mutually with other noise, by with detected clash analysis and judgement, send alerting signal by warning device, and alerting signal is sent to remote server by the radio communication device in the warning device, so both can in the shortest time, obtain traffic hazard warning message the most accurately and timely, and can effectively know the place where the accident occurred point.
