[0023] like Figure 1-Figure 3 As shown, this embodiment provides an infrared vehicle detector, comprising a column housing 1 having a rectangular cross-section and an infrared detection module 2 disposed therein. Infrared vehicle detectors are used in pairs, with one infrared vehicle detector serving as an infrared transmitter and the infrared detection module 2 therein serving as a transmitter, and the other infrared vehicle detector serving as an infrared receiver and the infrared detection module 2 therein serving as a receiver. The infrared transmitter and the infrared receiver utilize multiple infrared light beams for opposing purposes. The infrared transmitter emits infrared light to the infrared receiver using a "low-frequency emission, time-division detection" method. If a person or vehicle blocks any two or more adjacent light beams from the infrared transmitter for a specified period of time, the infrared receiver immediately outputs an alarm signal.

[0024] like Figure 1 and Figure 2 As shown, the front of the pillar housing 1 is provided with a glass window 3, and the inner side of the glass window 3 is provided with a fixing frame for fixing the infrared detection module 2 and bringing the infrared detection module 2 close to the glass window 3. The utility model brings the infrared detection module 2 close to the glass window 3, reduces the initial emission distance of the light source, effectively solves the problem of light source refraction and reception, and improves the vehicle detection effect.

[0025] One side of the pillar housing 1 is provided with a side door 4, which is provided with a first brim window structure 5. The other side of the pillar housing 1 is provided with a second brim window structure 6. The first and second brim window structures 5 and 6 provide ventilation and guide water flow, preventing the infrared vehicle detector from overheating and causing the device to malfunction, thereby improving the infrared vehicle detector's adaptability to complex outdoor environments.

[0026] The utility model can be applied to operate in high and low temperature environments, the overall operation is more stable, the installation and maintenance costs are reduced, and the appearance is neat and beautiful, which reduces the hardware equipment investment and implementation costs of enterprises in the construction of intelligent and information-based projects.

[0027] like Figure 3 As shown, in a specific embodiment, the fixing frame includes at least two fixing bars 7, and the infrared detection module 2 is sandwiched between the two fixing bars 7, thereby fixing the infrared detection module 2 so that the infrared detection module 2 is close to the glass window 3. Preferably, the fixing frame includes four fixing bars 7, two of which are arranged on both sides of the top of the infrared detection module 2, and the other two fixing bars 7 are arranged on both sides of the bottom of the infrared detection module 2, so as to improve the fixing effect of the infrared detection module 2.

[0028] To facilitate installation of the infrared detection module 2, the fixing bar 7 is L-shaped. One side of the fixing bar 7 is connected to the front inner wall of the pillar housing 1, and the other side of the fixing bar 7 is connected to the infrared detection module 2. The fixing bar 7 is connected to the front of the pillar housing 1 via bolts and nuts. The bolts penetrate the pillar housing 1 and the fixing bar 7 and then connect to the nuts. The fixing bar 7 and the infrared detection module 2 are secured with screws. This utility model utilizes the fixing bar 7 to secure the infrared detection module 2, keeping it close to the glass window 3, effectively improving the overall structural stability of the infrared vehicle detector.

[0029] In one embodiment, the distance between the bottom of the infrared detection module 2 and the bottom of the column housing 1 exceeds 50 cm. Some infrared vehicle detectors have infrared detection modules 2 that are too low to the ground. In severe rainy or snowy weather, muddy water splashed by passing wheels adheres to the surface of the glass window 3, partially blocking infrared rays and causing infrared detection misjudgments, impacting actual detection results. To address this issue, the present utility model redesigns the glass window 3 on the front of the column housing 1. Based on the size and speed of the truck's wheels, the distance between the infrared detection module 2 and the ground is calculated to exceed 50 cm. Experimental testing has also been conducted, effectively resolving the issue of infrared detection misjudgments.

[0030] In a specific embodiment, the first brim window structure 5 and the second brim window structure 6 are respectively arranged on two opposite sides of the column shell 1, which is conducive to achieving air convection inside the column shell 1 and improving the heat dissipation effect of the infrared vehicle detector.

[0031] To facilitate installation of the infrared vehicle detector, a base plate 8 is provided at the bottom of the column housing 1. Mounting holes are provided in the base plate 8, which is bolted to the ground. Preferably, the mounting holes are strip-shaped mounting holes 9. The base plate 8 is rectangular, with strip-shaped mounting holes 9 at each of its four corners. This facilitates adjustment during mounting, improving the ease of installation of the infrared vehicle detector.

[0032] In the description of the present utility model, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, and can be fixedly connected, detachably connected, or integrated; can be mechanically connected or electrically connected; can be directly connected or indirectly connected through an intermediate medium, can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood. In addition, the specific features, structures, etc. described in the embodiment are included in at least one embodiment. Under the condition that there is no contradiction, those skilled in the art can combine the features of different embodiments.
