With the increase of the pressure of traffic passage, the risk of accidents also increases, and the traffic monitoring system is of great importance for monitoring pedestrians and vehicles in the road.

In sensor-based pedestrian and vehicle identification, detection of pedestrians and vehicles is based on associated photoelectric switches, such as infrared emitters, laser proximity switches, and the like. The photoelectric switches are arranged on two sides of a road, and can trigger the sensors when pedestrians and vehicles pass by, so that whether the pedestrians and the vehicles pass by or not is directly detected. The sensor in this mode is low in price, deploys simply moreover, and the cost of later maintenance is lower, but the sensor can only respond to the end and whether have pedestrian or vehicle to pass through, can not effectively distinguish vehicle and pedestrian.
Consider the lower problem of current people's car identification system's precision, the utility model aims to provide a people's car identification circuit and people's car discernment alarm device, this technique can be applied to the in-process of people's car discernment, describes through specific embodiment below.
In order to understand the present embodiment, a man-car identification circuit disclosed in an embodiment of the present invention is first described in detail, and a schematic diagram of the man-car identification circuit is shown in fig. 1.
The circuit includes: the control circuit 110, and the flashing lamp control circuit 120, the horn control circuit 130, the first photoelectric switch 140 and the second photoelectric switch 150 that are connected with the control circuit 110. The transmitting terminal 141 of the first photoelectric switch transmits a photoelectric switch signal to the receiving terminal 142 of the first photoelectric switch; the transmitting terminal 151 of the second opto-electronic switch transmits an opto-electronic switching signal to the receiving terminal 152 of the second opto-electronic switch. When a pedestrian or a vehicle passes through the first photoelectric switch 140 or the second photoelectric switch 150, the photoelectric switch signal changes, and at this time, the first photoelectric switch 140 or the second photoelectric switch 150 acquires an instruction that the pedestrian or the vehicle passes through the photoelectric switch signal.
The control circuit 110 includes a PLC controller 111 and a remote control circuit 112 connected to each other.
The transmitting terminal 141 of the first photoelectric switch and the transmitting terminal 151 of the second photoelectric switch are arranged on one side of the road; the receiving terminal 142 of the first photoelectric switch and the receiving terminal 152 of the second photoelectric switch are disposed at the other side of the road. The distance between the first photoelectric switch 140 and the second photoelectric switch 150 is set according to actual conditions. The distance between the two switches is usually required to be larger than the area occupied by the pedestrian when the pedestrian walks, so that the two photoelectric switches cannot be blocked simultaneously but are blocked sequentially when the pedestrian walks in the normal running direction of the road; however, when the automobile runs along the normal running direction of the road, the two photoelectric switches are shielded at the same time. Therefore, the judgment of pedestrians and vehicles is realized according to whether signals for shielding two photoelectric switches simultaneously exist.
In general, a pin of the light receiver disposed at the receiving end of the photoelectric switch is an output end of the photoelectric switch, and output ends of the first photoelectric switch 140 and the second photoelectric switch 150 are respectively connected to a signal input end of the PLC controller;
the signal output end of the PLC controller is connected to the flashing light control circuit 120 and the horn control circuit 130. The flashing light control circuit 120 is used for controlling the flashing light to be turned on and turned off, and the horn control circuit 130 is used for controlling the horn to be turned on and turned off. When finding that the pedestrian walks into the vehicle driving road, the first photoelectric switch 140 and the second photoelectric switch 150 are shielded in sequence, when the pedestrian is detected on the road through the judgment of the shielding time, the explosion flash lamp control circuit 120 gives an alarm, the horn control circuit 130 controls the horn to broadcast, and meanwhile, the remote control circuit 112 uploads the dangerous information to the remote service for remote alarm.
In the above embodiment, the circuit may deploy the positions of the photoelectric switches according to the spatial distance in the road occupied by the pedestrian and the vehicle, and distinguish the pedestrian from the vehicle according to the response time of the photoelectric switches, so as to solve the problems of high cost and easy occurrence of false alarm in the video-based pedestrian and vehicle identification system in the prior art, and solve the problem that the pedestrian and the vehicle cannot be distinguished in the sensor-based pedestrian and vehicle identification system.
On the basis of the above embodiment, the embodiment of the present invention provides another people and vehicles identification circuit, as shown in fig. 2, the people and vehicles identification circuit further includes a handrail control circuit 170.
The handrail control circuit 170 is connected to the signal output terminal of the PLC controller 111 for controlling the lifting and dropping of the handrail.
In some embodiments, the human-vehicle identification circuit further includes a third photoelectric switch 160; the third photoelectric switch 160 is arranged at two sides of the road behind the second photoelectric switch 150 along the driving direction of the road, and the transmitting end 161 of the third photoelectric switch and the transmitting end 141 of the first photoelectric switch are positioned at the same side of the road; the receiving end 162 of the third photoelectric switch and the receiving end 142 of the first photoelectric switch are located on the same side of the road. As shown in particular in fig. 2.
In a specific implementation process, the distance between the first photoelectric switch and the second photoelectric switch is 100cm-120 cm; the length is the length that most motorcycles or bicycles can cover, so when the motorcycle or the bicycle runs to the moment, the first photoelectric switch and the second photoelectric switch can be shielded at the same time.
The distance between the second photoelectric switch and the third photoelectric switch is 200cm-300cm, and the distance between the first photoelectric switch and the second photoelectric switch is 100cm-120cm, so that the length between the first photoelectric switch and the third photoelectric switch is 300cm-420cm, which is the length covered by most automobiles, and therefore, when the automobiles run to the moment, the three photoelectric switches can be shielded at the same time.
In some embodiments, the height of the photoelectric switch from the ground is 10cm-100 cm. If the setting is too low, the vehicle is easily shielded by other sundries and garbage on the road, and if the setting is too high, some children or other vehicles with lower stature can not detect the vehicle, so the height is set between 10cm and 100cm from the ground.
In some embodiments, the optoelectronic switch is a laser diode, a laser diode grating, an infrared diode grating, or a laser proximity switch.
In some embodiments, the remote control circuit is internally provided with one or more transmission protocol modules selected from a wired network module, a WIFI module, a GSM module, a 4G module, and a 5G module.
The module in the remote control circuit can upload the result obtained in the human-vehicle identification circuit to a remote server, and can send related instructions to command or warn pedestrians and vehicles in the road through the remote server.
When the vehicle is running in the forward direction, the vehicle passes through the first photoelectric switch 140, the second photoelectric switch 150 and the third photoelectric switch 160 in sequence, and because the length of the vehicle is greater than the distance between the first photoelectric switch 140 and the third photoelectric switch 160, the vehicle can block the first photoelectric switch 140, the second photoelectric switch 150 and the third photoelectric switch 160 at the same time. At this time, the PLC controller determines that the vehicle driving on the road section is an automobile according to the related signals generated by the first photoelectric switch 140, the second photoelectric switch 150, and the third photoelectric switch 160 due to blocking. Since the first photoelectric switch 140 is blocked first, the vehicle is a forward-traveling vehicle.
When the vehicle runs in the reverse direction, the vehicle passes through the third photoelectric switch 160, the second photoelectric switch 150, and the first photoelectric switch 140 in this order, and the third photoelectric switch 160 is blocked first, so that the vehicle runs in the reverse direction. At this time, the flashing light control circuit 120 will give an alarm, and the horn control circuit 130 will control the horn to broadcast, warn the vehicles in the section of the road in the wrong direction, and give an early warning to other vehicle drivers on the surrounding roads. Meanwhile, the remote control circuit 112 uploads the danger information to a remote service for remote alarm, so that the traffic command center can conveniently perform subsequent tracking processing on the vehicle. If a railing is provided, the railing in the road can be controlled by the railing control circuit 170 to intercept the retrograde vehicle.
When the motorcycle or the bicycle runs on the road section in the forward direction, the motorcycle or the bicycle passes through the first photoelectric switch 140, the second photoelectric switch 150 and the third photoelectric switch 160 in sequence, and because the length of the motorcycle or the bicycle is greater than the distance between the first photoelectric switch 140 and the second photoelectric switch 150, the motorcycle or the bicycle can shield the first photoelectric switch 140 and the second photoelectric switch 150 at some time. At this time, the PLC controller may determine that the vehicle running on the road is a motorcycle or a bicycle according to the related signals generated by the first photoelectric switch 140 and the second photoelectric switch 150 due to the shielding. Since the first photoelectric switch 140 is shielded first, the motorcycle or the bicycle travels in the forward direction.
Similar to the recognition principle of reverse driving of an automobile, when the third photoelectric switch 160 is shielded by the motorcycle or the bicycle first, the motorcycle or the bicycle can be judged to be in reverse driving, the explosion flash lamp control circuit 120 can give an alarm at the moment, the horn control circuit 130 can control the horn to broadcast, the motorcycle or the bicycle driver in the road section can be warned, and early warning can be performed on the vehicle drivers on the surrounding roads. At the same time, the remote control circuit 112 will upload the danger information to a remote service for remote alarming. If a railing is provided, the railing in the road can be manipulated by the railing control circuit 170 to intercept the retrograde motorcycle or bicycle.
When a pedestrian walks in the forward direction, the pedestrian walks through the first photoelectric switch 140, the second photoelectric switch 150 and the third photoelectric switch 160 in sequence, and the first photoelectric switch 140, the second photoelectric switch 150 and the third photoelectric switch 160 cannot be shielded simultaneously in the walking process of the pedestrian, so that the PLC judges that the pedestrian passes through the road section according to the condition of no simultaneous shielding. Since the first photoelectric switch 140 is blocked, the pedestrian walks in the forward direction. Similar to the judgment of the retrograde motion situation, when the pedestrian firstly shelters the third photoelectric switch 160, the pedestrian can be judged to be retrograde motion, at this moment, the flashing light control circuit 120 can give an alarm, the horn control circuit 130 can control the horn to broadcast, the pedestrian on the road section is warned, and early warning is carried out on the vehicle drivers on the surrounding roads. At the same time, the remote control circuit 112 will upload the danger information to a remote service for remote alarming. If a railing is arranged, the railing in the road can be controlled by the railing control circuit 170 to intercept the pedestrian in the wrong direction.
According to the embodiment, the plurality of photoelectric switches are arranged and the distance between the photoelectric switches is combined for setting, so that pedestrians, bicycles, motorcycles and automobiles in roads can be accurately identified, and the problem that the vehicles and the pedestrians cannot be effectively distinguished in the traditional sensor-induction-based identification of the pedestrians and the vehicles is solved.
