Description

Technical Field

[0001] The utility model relates to the field of sensing equipment, in particular to a detector with multi-sensing functions. Background Art

[0002] With the development of science and technology, vehicle detection equipment on highways is becoming more and more intelligent. In order to improve the intelligence of vehicle detection, people have developed equipment that can detect vehicles at highway entrances, that is, radars for detecting vehicles and auxiliary cameras are arranged at the highway entrances to perform vehicle detection functions. However, existing vehicle detectors are not intelligent, cheap, and easy to install. During the operation of the detector, it needs to be fixedly installed in a single-lane highway entrance and exit with an installation position. Therefore, existing vehicle detectors are mostly used in single-lane highway entrances and exits. Therefore, it is necessary to develop a multi-sensing detector that can be portable and installed and is more intelligent. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and to provide a detector which is portable, can sense multiple objects, can be applied to various scenes, and is compact and easy to install.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A multi-sensing detector includes a laser radar sensing system, a human body sensing system and a millimeter wave radar sensing system, and also includes a control center. The laser radar sensing system, the human body sensing system and the millimeter wave radar sensing system are respectively connected to the control center. The laser radar sensing system feeds back a real-time distance value to the control center, and the control center controls the laser radar sensing system to perform algorithm calculation on the distance value fed back, thereby realizing the function of detecting whether a vehicle passes by.

[0006] Specifically, the laser radar perception system includes a laser radar, and the laser radar is installed on the front side of the detector.

[0007] Furthermore, the laser radar of the laser radar perception system has different communication interfaces, and the communication interfaces can be replaced at any time according to the interface requirements of the control panel, such as TTL communication interface, 485 communication interface, and CAN communication interface. The laser radar is connected to the control center for communication through the communication interface. According to the distance signal fed back by the laser radar, when the laser radar detects that an object passes through the laser radar, the real-time distance of the radar changes. That is, after the distance value is set in advance, the laser radar perception system is turned on, and the pre-set distance value is compared with the real-time distance value fed back by the laser radar. If the pre-set distance value is greater than the real-time feedback distance value, a vehicle has passed through the range mapped by the laser radar, and the control center uses an algorithm to deduce whether the laser radar perception system senses whether a vehicle has passed, thereby realizing the vehicle detection function.

[0008] Furthermore, the human body perception system includes a human body perception radar, and the human body perception radar is installed below the detector.

[0009] Furthermore, the human perception system can sense whether there is an object moving within 1-10 meters, and the human perception radar is installed under the detector to achieve 360-degree monitoring without blind spots. According to the human body signal fed back by the human perception radar, when a pedestrian passes within 1-10 meters of the human perception radar, the pedestrian data or the auxiliary data of the object volume monitored by the human perception radar changes and is reported to the control center. The control center combines the internal algorithm to determine whether there is a pedestrian, thereby realizing the function of human perception.

[0010] Furthermore, the millimeter-wave radar sensing system includes two millimeter-wave radars, and the millimeter-wave radars are installed one on each side.

[0011] Furthermore, the millimeter-wave radar perception system can sense the moving trajectory of objects between 1 and 60 meters. When an object enters the monitoring range of the millimeter-wave radar, the millimeter-wave radar captures the moving trajectory, speed, and volume of the object, and reports it to the millimeter-wave radar perception system in the form of data. The millimeter-wave radar is connected to the control center, and the control center receives the millimeter-wave radar data, and uses the internal algorithm of the control center to judge the volume and speed of the object to determine whether it is a vehicle, pedestrian, or animal, thereby realizing the perception functions of vehicles, humans, animals, and objects.

[0012] Furthermore, the control center has a variety of rich interfaces, such as 485 communication interface, CAN communication interface, and TTL communication interface for connecting the laser radar, the human body sensing radar, and the millimeter wave sensing radar to the control center. The control center is the core of the detector and is used to aggregate the data of the laser radar system, the human body sensing system, and the millimeter wave radar sensing system, and the data after algorithm processing, thereby realizing the function of multi-sensory detection.

[0013] The utility model has the following beneficial effects: the utility model provides a detector with multi-sensing functions, which can utilize the distance value, object trajectory, object speed, and object volume preset by the laser radar sensing system, the human body sensing radar system, the millimeter wave radar sensing system, and the control center. That is, after the distance value, object trajectory, object speed, and object volume are preset, the laser radar sensing system, the human body sensing radar system, and the millimeter wave radar sensing system are turned on, and the detector can feedback whether there is a vehicle passing by, the speed of the vehicle, whether there are pedestrians passing by, and whether there are animals passing by. Within the monitoring range, the detector can automatically judge vehicles, pedestrians, and animals, and the detector is small and easy to install. Therefore, the detector can not only accurately judge the type and status of objects within the monitoring range, but also has an easy installation and is not restricted by environmental factors.

Figure 1, a multi-sensing detector, including a laser radar sensing system, a human sensing system and a millimeter wave radar sensing system, characterized in that: it also includes a control center and a vehicle, human, animal, and object sensing system, the laser radar sensing system, the human sensing system and the millimeter wave radar sensing system are respectively connected to the control center, the vehicle, human, animal, and object sensing system feeds back the distance, speed, and state between the detector and the object in front to the control center, and the control center controls the vehicle, human, animal, and object sensing system to perform data interaction to determine the real-time situation around the sensor and report it, thereby realizing real-time judgment of the perceived vehicle, human, animal, and object. It should be noted that multi-sensing technology has been used as an existing technology and has been applied in other fields, such as ultrasonic radars for detecting the number of vehicles in existing high-speed toll stations, that is, there are already control centers that can realize vehicle counting and sensing and radar sensing systems connected thereto in the existing technology, so this application does not make a cumbersome description of them; under the guidance of the utility model, those skilled in the art are able to combine the existing technology and the content of this application to make the technical solution of this application and achieve the corresponding technical effect.

[0018] Specifically, the laser radar perception system includes a laser radar 1, which is installed on the front of the detector. The laser radar 1 is connected to the control center 5. The laser radar 1 can be used at 132°

[0019] The phase difference and time difference between light emission and reception are calculated by the principle of time-of-flight method within the horizontal viewing angle and the 9° vertical viewing angle to convert the distance between the detector and the passing vehicle, and a pre-initial distance range is set. When the distance value of the laser radar 1 is detected, a vehicle signal is sent. The ranging of the laser radar 1 used in the utility model is more accurate in detecting whether there is a vehicle.

[0020] Furthermore, the human body sensing system includes a human body sensing radar 2, which is installed under the detector. The human body sensing radar 2 is connected to the control center 5, and the human body sensing radar 2 is used to monitor pedestrians within 1-10 meters and 360 degrees without blind spots, and an initial human body fluctuation setting value is set. When a pedestrian passes within the range of the detector, the set human body fluctuation is triggered and fed back to the control center 5. The initial value is used by the control center to determine whether there is a pedestrian, thereby realizing the human body sensing function.

[0021] Furthermore, the millimeter wave radar sensing system includes a millimeter wave radar 2 and a millimeter wave radar 3, wherein the millimeter wave radar 2 is installed on the left side of the detector and the millimeter wave radar 3 is installed on the right side. The millimeter wave radar 2 and the millimeter wave radar 3 are connected to the control center 5. When the vehicle detector is installed on the left side of the driving direction, the millimeter wave radar 2 is used to detect pedestrians and vehicles in the direction of oncoming vehicles, and the millimeter wave radar 3 is used to detect pedestrians and vehicles when outgoing vehicles are detected. If it is installed on the right side of the driving direction, the opposite is true. The millimeter wave radar 2 and the millimeter wave radar 3 can be used to monitor in real time whether there are oncoming vehicles on the road, the speed of oncoming and outgoing vehicles, the amount of traffic, whether there are pedestrians passing, and report feedback to the control center 5, thereby realizing the functions of assisting human body sensing, whether there are oncoming vehicles, vehicle speed, and traffic flow.

[0022] Furthermore, the control center 5 includes an MCU core microcontroller unit and an extended function circuit board, and the control center 5 is installed in the center of the detector housing. As the absolute core of the detector, the control center 5 not only has communication interfaces adapted to the laser radar 1, the human body sensing radar 2, the millimeter wave radar 3 and the millimeter wave radar 4, but also receives data from the laser radar 1, the human body sensing radar 2, the millimeter wave radar 3 and the millimeter wave radar 4 for algorithm judgment, thereby realizing the multi-sensing function.
