Detailed Description

The utility model will be further described in detail with reference to the following examples, which are given in the accompanying drawings.

As shown with reference to figures 1-3,

highway is ultrahigh alarm for entry based on TOF sensor 1 includes

A TOF sensor 1 for detecting whether the vehicle is ultrahigh;

the daytime alarm 2 is used for sending high-volume alarm and is positioned outside the detection station;

the night alarm 3 is used for giving out low-volume alarm and is positioned in the detection station room;

the daytime alarm 2 and the night alarm 3 are alternately switched to work or suspend work through the time control switch 4.

TOF sensor 1 uses a tiny laser to emit infrared light, where the light produced bounces off any object and returns to the sensor. Sensors are typically used to measure the distance between an object and the sensor based on the time difference between the emission of light and its return to the sensor after being reflected by the object.

TOF sensor 1 in this setting can detect the height of level to also can be the height that detects the vertical direction, and the position according to setting up is different, can judge whether there is the vehicle superelevation through the detection mode of difference. In this scheme, through setting up two kinds of schemes of alarm 2 and night alarm 3 in daytime respectively, make the optimization to the alarm of night and daytime to the alarm setting in daytime can utilize the high tone volume to report the alarm outside detecting station, can not have the disturbing citizen phenomenon, also can provide obvious alarm effect simultaneously. And the general environmental noise at night is little to need reduce noise pollution, install night alarm 3 in detecting station, can further reduce the noise pollution that causes the environment through indoor low volume alarm, can produce sufficient alarm effect simultaneously, the suggestion staff handles the superelevation condition. The corresponding alarms are respectively opened and closed aiming at different time periods through the time control switch 4, so that intelligent alarm switching is realized, manual operation is not needed, and automation is improved.

Preferably, the daytime alarm 2 and the night alarm 3 are audible and visual alarms.

Audible-visual annunciator's alarm effect is more strong to being in the detection station at night indoor, external sound alarm signal is more weak, and the alarm through the light can see through the window that detects the station and send out the police dispatch newspaper to the driver, possesses more direct alarm effect.

In order to make the detection signal more stable, the ultrahigh alarm of this scheme still includes delay switch 5 who is connected to a TOF sensor 1, alarm 2 and night alarm 3 all are connected with delay switch 5 directly or indirectly during the daytime, and when delay switch 5 switched on, alarm 2 or night alarm 3 reported to the police during the daytime.

And stabilizing the alarm signal by using the time delay effect of the time delay switch 5, and controlling the alarm signal to be transmitted from the TOF sensor 1 to the day alarm 2 and the night alarm 3 by using the time delay switch 5. Can avoid birds, winged insects and the like from causing false alarm.

In addition, the ultrahigh alarm is used for being installed on two sides of an expressway entrance rod piece, the TOF sensor 1 of the ultrahigh alarm is horizontally arranged and used for detecting whether a vehicle enters the horizontal height detected by the TOF sensor 1, and when the TOF sensor 1 detects that the ultrahigh vehicle enters the horizontal height detected by the TOF sensor, the ultrahigh alarm sends an ultrahigh signal to the daytime alarm 2 or the nighttime alarm 3.

The preferable ultrahigh alarm of this scheme adopts the mode of horizontal detection to detect the vehicle height, for example set up TOF sensor 1 as horizontal orientation, be located the height of 4m height, can block TOF sensor 1 when the vehicle that exceeds 4m height passes through, TOF sensor 1 will receive the detected signal or the numerical variation of distance at this moment, and then judge as the ultrahigh vehicle, and can also judge the lane that the vehicle was located through the distance of this numerical variation, for example road width 20m (except roadside tooth), each lane occupies 4 meters wide, 5 lanes altogether, can judge the lane that is located to the numerical variation of distance that TOF sensor 1 detected through this detection analysis, when the numerical variation that TOF sensor 1 detected is 20m becomes 4m, then mean that this lane enters the second lane, and at the ultrahigh of second lane. Based on this sensor and the position that sets up thereof, can provide quick location and superelevation detection's effect.

If the lane is left and right sides double lane, can be on same montant respectively to both sides orientation installation this scheme's superelevation alarm, can detect the superelevation in both sides lane simultaneously. Compared with the existing infrared sensor, the infrared sensor has the advantages that the sensors matched with each other need to be arranged on the two sides of the vertical rod, and complexity in circuit layout and assembly is reduced.

Specifically speaking, daytime alarm 2 and night alarm 3 all are connected with independent time switch 4, and two independent time switch 4 all are connected to delay switch 5, and when delay switch 5 circular telegram, delay switch 5 provides alarm signal to daytime alarm 2 and/or night alarm 3 through two independent time switch 4.

The corresponding alarm devices are blocked and communicated through the two independent time control switches 4, the working modes of the alarm devices can be better switched, the two time control switches 4 can be started at the same time through intervention, and then the day alarm devices 2 and the night alarm devices 3 can be communicated at the same time to receive signals so as to start the indoor and urban alarm functions.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model, and are considered to be within the scope of the utility model.
