Horn Sound Detection Highway Toll Station Service Satisfaction Evaluation System Device

technical field

The invention relates to a road toll service satisfaction evaluation system device, in particular to a horn sound detection road toll station service satisfaction evaluation system device matched with a road toll station.

Background technique

Highway is the product of social and economic development, and fast traffic is the symbol of modern civilization. As the first-line service window of the highway, the highway toll station, civilized, efficient, and fast release are the social requirements of the times for the construction of toll stations. Since the Shanxi Provincial Highway Administration System launched the creation of "civilized toll windows", our company has attached great importance to it, carefully organized, formulated implementation plans, detailed work details, and solidly promoted the creation activities. Through on-the-spot observation and online retrieval, the existing highway toll station service satisfaction evaluation system is operated by buttons. Set one red button and one green button under the toll window, and let the driver vote by pressing the button. After on-the-spot investigation, the button is too far away from the driver, and it is difficult for the driver's hand to reach the button. In addition, pressing the button also wastes driving time. Therefore, this highway toll station service satisfaction evaluation system is useless! The invention has a unique trick, allowing the master driver to vote with the signal of the horn sound that is readily available, and the horn sound detection device uses the mean value filter algorithm to filter the stray impact sound signals in the environment, determine the authenticity of the signal, and obtain the true evaluation of the master driver . The function of the horn sound detection road toll station service satisfaction evaluation system device of the present invention is civilized and efficient, ensuring polite greetings when cars come, timing and efficient charging, fast release, and the driver pressing the button to vote when the car is leaving. traffic efficiency. This invention is also the specific achievement of our company "focusing on improving the civilized service quality of toll station windows, and shaping the image of urban city windows through the construction of toll station service satisfaction evaluation system".

Contents of the invention

The service satisfaction evaluation system device of the horn sound detection road toll station of the present invention consists of 1# ground sense coil (1), 2# ground sense coil (2), 3# ground sense coil (3), single-chip microcomputer control board (4), voice amplifier The circuit board (5), horn sound detection device (6), LED display screen (7), horn (8) and automatic railing (10) are formed, and it is characterized in that, accept evaluation information with horn sound detection device (6), single-chip microcomputer The control panel (4) is electrically connected to the voice amplifier circuit board (5), the LED display screen (7), the loudspeaker (8) and the automatic railing (10). The working description of the service satisfaction evaluation system device of the horn sound detection road toll station of the present invention: the vehicle enters the toll station at a high speed (coming) to set the distance, the vehicle presses to the 1# ground sense coil, and the voice player sends out the sentence "Welcome to XX" , and at the same time remind the toll staff to prepare for the car pick-up toll service, and the LED display will display "Welcome to XX". The vehicle presses to the 2# ground induction coil, stops at the toll window, and the LED display shows "countdown to set time" and begins to count down the countdown. The charge is completed within the specified time, and the LED display will flash "Please evaluate: if you are satisfied, please click the horn; if you are not satisfied, please do not click". The single-chip microcomputer control board sends a 2-second timing detection command to the direction, and the horn sound detection device detects the horn sound information from the vehicle horn, measures the level of the horn sound, and sends a signal to the single-chip microcomputer control board after arithmetic mean filtering. After a delay of 2 seconds, the railing will be raised regardless of whether the vote is cast or not, and vehicles will pass. Then turn off the horn sound detection device to avoid other stray sound interference, and the LED display will display "goodbye, thank you".
