Technical Field
[0001] This utility model relates to the field of vehicle detection technology for highway toll lanes in intelligent transportation, specifically an electromagnetic pulse wave vehicle separator. Background Technology
[0002] With the development of transportation, toll lanes are widely used at highway entrances and exits. Traditional toll lanes typically have coil-type or optical encoders installed at their front ends for vehicle separation and object detection, making them an indispensable electronic device in intelligent transportation systems. However, traditional toll lanes mostly use coil-type or optical encoders for vehicle separation. During use, these sensors are often affected by environmental factors, leading to low detection rates, unstable performance, and signal reception errors. They also fail to achieve vehicle-pedestrian separation, have limited functionality, are cumbersome to install, and have high installation and maintenance costs, significantly reducing their practicality. Therefore, we propose an electromagnetic pulse wave vehicle separator. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an electromagnetic pulse wave vehicle separator to solve the problems mentioned in the background art, such as the low vehicle detection rate, unstable detection performance, and incorrect signal reception caused by environmental factors during the use of traditional coil vehicle detectors and grating vehicle detectors, which are unable to achieve separation of people and vehicles, have limited functionality, are cumbersome to construct, and have high installation and maintenance costs. These problems greatly reduce the practicality of coil vehicle detectors and grating vehicle detectors.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic pulse wave vehicle separator, comprising: a multi-sensor electromagnetic pulse wave detection unit, an electromagnetic pulse wave laser sensor detection unit, a gyroscope attitude sensing sensor, a human body sensing sensor, a comprehensive positioning sensor, an electromagnetic pulse wave logic processing unit, a control unit, a dedicated waterproof aviation connector, and a DB9 connector.
[0005] The core components of the vehicle transfer unit consist of an electromagnetic pulse wave detection module, an electromagnetic pulse wave laser detection module, and an electromagnetic pulse wave integrated logic processing module. Its appearance includes a casing and a support column. An electromagnetic pulse wave detection unit is located on the front of the casing.

[0010] This electromagnetic pulse wave vehicle separator detects vehicles entering, present, and leaving its detection area. The detection results are derived from components including a multi-sensor electromagnetic pulse wave detection unit, an electromagnetic pulse wave laser sensor detection unit, a gyroscope attitude sensing sensor, a human body sensing sensor, and a comprehensive positioning sensor. The integrated logic processing unit then uses multi-dimensional, comprehensive scene-based, and large-model intelligent algorithms to produce a comprehensive logical output.

The electromagnetic pulse wave vehicle separator is easy to install and debug. With low cost and simple after-sales maintenance, it has high promotional value. The electromagnetic pulse wave vehicle separator effectively detects vehicle entry, presence, and departure. The equipment is used in toll lanes and related lanes, installed on the unidirectional side of the island.

It is suitable for continuous, uninterrupted operation in the field and can automatically compensate for temperature. It operates 24 / 7, unaffected by sound waves and environmental factors (acid, smoke, fog, rain, snow, ice), with strong anti-interference capabilities. Multiple electromagnetic pulse wave vehicle separators used simultaneously in the same or adjacent lanes have inter-frequency anti-interference functionality. Flow accuracy (vehicles) reaches 99.99%, and the pedestrian-vehicle separation rate reaches 99.99%, completely achieving pedestrian-vehicle separation.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Referring to Figures 1-3, in order to address the problems of low vehicle detection rate, unstable detection performance, and incorrect signal reception caused by environmental factors in the use of traditional coil vehicle detectors and grating vehicle detectors, which result in limited functionality, cumbersome construction, high installation and maintenance costs, and thus reduced practicality, an electromagnetic pulse wave detection unit 1 is provided on the front side of the housing 9. A gyroscope attitude sensing sensor 2 is installed on the right side of the wave detection unit 1. A human body sensing sensor 3 is installed below the gyroscope attitude sensing sensor 2. A positioning sensor 4 is installed to the right of the human body sensing sensor 3. An electromagnetic pulse wave laser sensor detection unit 5 is installed on the outer surface of the housing 9. An electromagnetic pulse wave logic processing unit 6 is installed inside the housing 9. A control unit 7 is installed on the left side of the electromagnetic pulse wave logic processing unit 6. A power module 8 is installed at the bottom inside the housing 9. A base column 10 is fixedly installed on the lower side of the housing 9.
[0015] Working principle: When using this electromagnetic pulse wave vehicle separator, when a vehicle or pedestrian passes through, is present in, or leaves the detection area of this device, the detection results of the electromagnetic pulse wave detection unit 1 of the electromagnetic pulse wave vehicle separator are combined with the detection results of the electromagnetic pulse wave laser sensor detection unit 5 of the electromagnetic pulse wave vehicle separator, and the electromagnetic pulse wave comprehensive logic processing unit 6 of the electromagnetic pulse wave vehicle separator performs comprehensive logic output through the built-in intelligent algorithm.
[0016] Electromagnetic pulse wave detection unit 1 integrates both continuous electromagnetic pulse wave and electromagnetic pulse wave. The continuous electromagnetic pulse wave, through high-frequency transmission and reception, ensures real-time detection, but cannot distinguish between people and vehicles, and its energy is limited, resulting in a relatively blurry target outline. Simultaneously, the electromagnetic pulse wave, through high-energy transmission and reception, is normally in a dormant state, resuming transmission approximately 5ms after the continuous wave detects a target. Its energy value is relatively large. To avoid crosstalk between devices, the electromagnetic pulse wave cannot be continuously transmitted. The electromagnetic pulse wave primarily distinguishes between people and vehicles. Electromagnetic pulse wave detection unit 1 differentiates between human reflections and vehicle reflections through the initial fusion of the two signals. This distinguishes between people and vehicles. Then, through internal logic processing and combination, the detection results of the gyroscope attitude perception sensor 2 and the human body induction sensor 3 are fused and output as basic detection results. These results are then provided to the electromagnetic pulse wave logic processing unit 6 to achieve the detection of passing people or vehicles, vehicle size detection, vehicle category detection, wheel detection, and object detection. Pulse waves are used instead of traditional coil vehicle detectors or grating vehicle detectors. This effectively avoids the problems of low vehicle detection rate, unstable detection performance, and incorrect signal reception caused by environmental factors during the use of vehicle separators. These problems include failure to achieve human-vehicle separation, limited functionality, cumbersome construction, high installation cost, and high maintenance cost.
[0017] Compared with related technologies, the electromagnetic pulse wave vehicle separator provided by this utility model has the following beneficial effects: (1) It can effectively avoid the problems of low vehicle detection rate, unstable detection performance, and incorrect signal reception caused by environmental factors during the use of vehicle separators, which cannot achieve separation of people and vehicles, have limited functionality, are complicated to construct, have high installation and maintenance costs, and are prone to malfunctions. At the same time, the electromagnetic pulse wave vehicle separator can adapt to various complex working environments, and adopts a small-volume integrated design with a simple body structure, stable performance, and reliable safety. It can quickly and effectively detect the movement trajectory of people and vehicles in the area to be inspected. It overcomes the defects of coil vehicle detectors and grating vehicle detectors, and can achieve a detection accuracy of over 99%. The electromagnetic pulse wave vehicle separator is easy to install and debug. It has low cost and simple after-sales maintenance, and has high promotional value.
[0018] (2) The electromagnetic pulse wave vehicle separator can effectively detect vehicle entry, presence, and departure. The equipment is used in toll lanes and related lanes, and is installed on the side of the island in one direction. It has vehicle detection and separation processing functions, multiple independent normally open and normally closed switch outputs, and also has TTL level output, RS485 serial port output and dual network interface output, which can easily meet the requirements of different equipment. It can be used for continuous uninterrupted operation in the field, and can automatically compensate for temperature. It can work 24 / 7 without interruption, and is not affected by sound waves and environmental factors (acid, smoke, fog, rain, snow, ice). It has strong anti-interference, and multiple sets of electromagnetic pulse wave vehicle separators can be used simultaneously in the same lane or adjacent lanes with inter-frequency anti-interference function.
[0019] (3) The flow accuracy (vehicles) of the electromagnetic pulse wave vehicle separator is as high as 99.99%, and the separation rate of people and vehicles is as high as 99.99%, which can completely realize the separation of people and vehicles.
[0020] (4) The electromagnetic pulse wave vehicle separator can filter people through dual-mode electromagnetic pulse wave sensing, and can accurately filter out false triggering caused by people. The electromagnetic pulse wave vehicle separator has inter-frequency anti-interference function in the same lane or adjacent lanes, and has the functions of resisting temperature changes and resisting ferromagnetic interference. The electromagnetic pulse radiation immunity meets the Class A requirements of human safety standards, and can work normally under a 1KHz sine wave signal with a frequency of 80MHz-2700MHz. The electromagnetic pulse wave vehicle separator can automatically detect, set, and calibrate one lane, enabling single-lane vehicle detection in toll lanes. It is more convenient to transport and install. In terms of performance, the electromagnetic pulse wave vehicle separator completely replaces loop detectors and optical encoders. It is multifunctional, stable, and features multi-sensor electromagnetic pulse wave detection, including electromagnetic pulse wave and terahertz sensing, and electromagnetic pulse wave laser sensor-assisted detection. It can automatically detect, set, and calibrate one lane, achieving single-lane vehicle detection in toll lanes. Where loop detectors and optical encoders cannot achieve pedestrian-vehicle separation, the electromagnetic pulse wave vehicle separator boasts a pedestrian-vehicle separation rate of up to 99.99%, completely separating pedestrians and vehicles. Its pedestrian filtering rate reaches 99.99%. Dual-mode electromagnetic pulse wave sensing accurately filters out false triggers caused by people, highlighting the practicality of the electromagnetic pulse wave vehicle separator.
