Description

Technical Field

[0001] The utility model belongs to a highway traffic control technology, in particular to a warning system for pedestrians not to enter a highway. Background Art

[0002] At present, there are often pedestrians or non-motor vehicles (bicycles, electric bicycles) illegally entering highways. The main reason is that the control of such behavior mainly relies on toll station staff, who are unable to discover them in time and take measures to stop them, let alone detect such illegal entrants at any time. After all, the traffic volume is large and it is a major traffic artery. They are always in a state of high alert to monitor passing vehicles, especially in shift changes and other links. It is easy to overlook pedestrians entering, and it is even more difficult to detect those who climb over the side of the highway to enter the highway. Utility Model Content

[0003] The purpose of the utility model is to provide a system that can timely detect and warn pedestrians entering the highway, so as to make up for the existing defect that pedestrians cannot be detected and prevented from entering the highway in time.

[0004] To achieve the above-mentioned purpose, the utility model provides a pedestrian prohibited highway warning system, comprising a support base with baffles arranged on three consecutive sides, an infrared sensor placed on the bottom plate of the support base, a rain shelter arranged above the support base to provide the infrared sensor with shelter from rain, and a voice alarm electrically connected to the infrared sensor through an electromagnetic relay;

[0005] The infrared sensor, electromagnetic relay and voice alarm are all connected to the distribution box through an air switch to obtain electrical energy;

[0006] The voice alarm stores warning words prohibiting pedestrians from entering and words for driving away, which are automatically played when the working power supply circuit is connected.

[0007] The utility model has the advantages of simple structure and easy assembly, and can effectively detect pedestrians who intend to enter the highway at any time and issue warnings in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0011] In order to make up for the existing defect that pedestrians cannot be found and stopped from entering the highway in time, this embodiment provides a Figure 1 The pedestrian prohibited highway warning system shown comprises a support base 2 (generally a rectangular support plate is selected) with baffles 1 arranged on three consecutive sides. The side (one side) without the baffle is installed close to the wall or fits with the pole body. The bottom plate of the support base 2 is placed with an infrared sensor 3, that is, the infrared sensor is purchased as a finished product and can be taken out and maintained at any time. At the same time, the development cycle and application cost are greatly reduced (the lowest selling price is obtained by purchasing from a large number of manufacturers), and the functions and performance can be purchased according to actual needs.

[0012] A rain shelter 4 is provided above the support base 2 for the infrared sensor 3 to avoid rain. It can be uniformly customized and can be anchored on a wall during specific installation, or it can be installed through a quick-release frame or various clip hoops. The infrared sensor 3 is electrically connected to the voice alarm 5 through an electromagnetic relay, that is, when a pedestrian approaches (the general detection range is within 3 to 5 meters), the infrared sensor 3 works, and its working circuit switch is used as a power supply switch of the electromagnetic relay, so that the electromagnetic relay is energized, thereby connecting the working circuit of the voice alarm 5. The voice alarm 5 stores warning words and expulsion words prohibiting pedestrians from entering, which are automatically played when the working power supply circuit is connected, thereby serving as a warning to approaching pedestrians. At the same time, it can warn the staff to stop the approaching pedestrians in time.

[0013] The infrared sensor 3, the electromagnetic relay and the voice alarm 5 are all connected to the distribution box through an air switch to obtain electrical energy (220V mains electricity is sufficient).

[0014] In order to detect pedestrians approaching the highway at a long distance as early as possible, the present embodiment provides a plurality of fixed poles 6 (lamp poles or monitoring poles or pillars in toll booths, or stainless steel poles alone) fixed within a range of 50 to 100 meters outside the highway entrance or at least 5 to 10 meters outside the highway roadside fence; wherein the fixed poles 6 fixed outside the highway entrance are evenly arranged and sequentially away from the highway entrance; or the fixed poles 6 fixed outside the highway roadside fence are evenly arranged in the extension direction of the passage close to the highway roadside fence; thereby realizing long-distance, multiple detections and continuous warnings to pedestrians approaching and intending to enter the highway, forming a strong and pressured continuous warning and expulsion, thereby playing a warning, expulsion, and even deterrent role to a great extent, greatly improving the warning effect.

[0015] As described above, a support base 2, an infrared sensor 3, an electromagnetic relay and a voice alarm 5 are fixed on each fixed rod 6; and the power supply cables on each fixed rod 6 are connected in parallel to the distribution box through an air switch (that is, each fixed rod 6 is matched with an air switch and does not affect each other).

[0016] In order to further maximize the warning effect, this embodiment is also equipped with at least one camera 7 (also purchased) on each fixed rod 6, which is connected to the security control host in the control room through a communication cable or a wireless signal connector, and the security control host displays the image of the camera 7 in real time through the partitioned large screen in the control room; a manual press alarm button is set in the control room, which is connected to the voice alarm 5 through a cable to connect the working power supply circuit of the voice alarm 5. In this way, double protection is achieved.

[0017] In order to cope with sudden power supply line failures, the present embodiment installs a photovoltaic power generation panel 8 on the top surface of the rain shelter 4, which is connected to a rechargeable battery 9 arranged below the rain shelter 4 and adjacent to the infrared sensor 3. The rechargeable battery 9 is connected through a power switching switch connected in series between the air switch and the distribution box (mainly switching between the mains and the rechargeable battery 9, with the mains power supply being given priority. When the mains power is cut off, the power supply is switched to the rechargeable battery 9. This is a general power switching control technology and will not be described here.). The rechargeable battery 9 is connected in parallel with the infrared sensor 3, the electromagnetic relay and the voice alarm 5 respectively through the power switching switch.
