[0038] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-2 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] The embodiment of the present application discloses a smart safety cone, which can identify vehicles traveling at high speeds and has good practicality.

[0040] Reference Figure 1 and Figure 2The smart safety cone includes a power module 1, a laser radar module 2, a control module 3, an alarm module 4, a positioning module 5, a communication module 6 and a distance setting module 7. Usually, during use, the smart safety cone needs to be placed in front of the defense area.

[0041] The power module 1 is used to provide power. In some specific embodiments, the power module 1 can be a battery, which can provide a power voltage of 12V and a current of 25000mA, and can work continuously for 48 hours.

[0042] The laser radar module 2 is used to emit laser at a preset frequency, and is used to detect the distance between the vehicle and the defense area according to the time of emitting the laser and the time of receiving the laser, and output a distance detection signal. It can be understood that the laser radar module 2 can make up for the deficiency of traditional acoustic radar that cannot identify high-speed vehicles. Not only that, the laser radar has strong anti-interference and high reflection power. It can also accurately scan vehicles outdoors, avoiding the problem that traditional infrared sensors are easily interfered by natural light outdoors. When the color of the vehicle body is darker, the problem of reflected signals being absorbed is not easy to occur.

[0043] In some specific embodiments, the laser radar module 2 emits laser at a frequency of 100 Hz. At this time, the laser radar module 2 can detect a vehicle with a speed of 150 km / h.

[0044] The control module 3 is respectively connected to the laser radar module 2 and the power module 1, and is used to receive a distance detection signal, and is used to output a first alarm signal when the distance value reflected by the received distance detection signal exceeds a first preset distance.

[0045] When the distance value reflected by the distance detection signal exceeds the first preset distance, it means that a vehicle has approached the defense area and may invade the defense area, and the control module 3 outputs the first alarm signal. On the contrary, when the distance value reflected by the distance detection signal does not exceed the first preset distance, there is no possibility of invading the defense area, and the first alarm signal is not output.

[0046] In some specific embodiments, when the control module 3 is connected to the laser radar module 2, a signal trigger circuit needs to be set up.

[0047] Specifically, the signal trigger circuit includes transistor Q14, transistor Q15, transistor Q16, transistor Q17 and multiple resistors. The base of transistor Q15 is connected to the control module 3 through resistor R68, its emitter is grounded, its collector is connected to the power module 1 through resistor R60, and resistor R61 is connected in parallel with resistor R60 and resistor R68. The base of transistor Q14 is connected to the collector of transistor Q15 through resistor R63, its emitter is grounded, its collector is connected to the power module 1 through resistor R59, and its collector is also connected to the RXD pin of the laser radar module 2. The base of transistor Q17 is connected to the TXD pin of the laser radar module 2 through resistor R77, its emitter is grounded, and its collector is connected to the power module 1 through resistor R74, and resistor R75 is connected in parallel with resistor R77 and resistor R74. The base of transistor Q16 is connected to the collector of transistor Q17 through resistor R76, its emitter is grounded, its collector is connected to power module 1 through resistor R73, and its collector is also connected to control module 3. Among them, transistor Q14, transistor Q15, transistor Q16, and transistor Q17 are all NPN transistors. In order to realize the above functions, corresponding transistors can also be selected according to the pin settings of control module 3.

[0048] In some specific embodiments, since the laser radar module 2 may still have errors when detecting the distance between the vehicle and the defense area, it is necessary to detect the distance between the same detected vehicle and the defense area twice when in use.

[0049] Furthermore, considering that when the safety cone is placed on the road, the road may be a road with multiple lanes, the laser radar module 2 may detect vehicles in other lanes during detection, thereby causing a false alarm. Therefore, a distance setting module 7 is also provided to limit the control module 3 when judging the distance reflected by the distance detection signal.

[0050] The distance setting module 7 is used to receive the interactive signal of human operation and output the operation signal. In some specific embodiments, the distance setting module 7 can be composed of buttons and peripheral circuits to reflect the settings of human input through high-level signals or low-level signals.

[0051] The control module 3 is connected to the distance setting module 7 and is also used to receive an operation signal and adjust the first preset distance when the operation signal is received.

[0052] It is understandable that in order to distinguish the severity of the vehicle intrusion into the defense area, the control module 3 also sets a second preset distance. When the distance value reflected by the distance detection signal is less than the second preset distance, it means that the vehicle has entered the defense area. At this time, the control module 3 outputs a second alarm signal. The second preset distance here is less than the first preset distance. On the contrary, when the distance value reflected by the distance detection signal is less than the first preset distance and greater than the second preset distance, it means that the vehicle has not entered the defense area. At this time, the control module 3 does not output the second alarm signal.

[0053] In some specific embodiments, the control module 3 may be an MCU.

[0054] The alarm module 4 is connected to the control module 3, and is used for receiving the first alarm signal and the second alarm signal, and for giving an alarm when the first alarm signal or the second alarm signal is received.

[0055] The alarm module 4 includes a sound alarm unit and a light alarm unit.

[0056] The sound alarm unit is connected to the control module 3, and is used to receive the first alarm signal, and is used to alarm when the first alarm signal is received. When the sound alarm unit does not receive the first alarm signal, it will not alarm. In some specific embodiments, the sound alarm unit can be a buzzer.

[0057] The light alarm unit is connected to the control module 3, and is used to receive the second alarm signal, and is used to alarm when receiving the second alarm signal. When the light alarm unit does not receive the second alarm signal, it will not alarm. In some specific embodiments, the light alarm unit can be an LED lamp.

[0058] The positioning module 5 is connected to the control module 3 and is used to record and output the position information of the safety cone. In some specific embodiments, the positioning module 5 can be a Beidou positioning system or a GNSS.

[0059] The communication module 6 is connected to the control module 3 and is used to transmit data stored in the control module 3. In some specific embodiments, the communication module 6 can be a 4G / 5G communication module 6.

[0060] The embodiment of the present application also discloses an early warning interaction platform.

[0061] Reference Figure 1 The early warning interaction platform includes an early warning command platform 8 and multiple smart safety cones disclosed in the previous embodiment.

[0062] Among them, the early warning command platform 8 is respectively connected to multiple command safety cones, and is used to receive the first alarm signal or the second alarm signal sent by the safety cones, as well as the positioning information, and is used to send the first alarm signal or the second alarm signal to the safety cones within the preset range when receiving the first alarm signal or the second alarm signal sent by a certain safety cone. Conversely, when the early warning interactive platform does not receive the first alarm signal or the second alarm signal, it will not send the first alarm signal or the second alarm signal. In addition, the early warning command platform 8 can also display the positions of all safety cones according to the received positioning information.

[0063] When the safety cone receives the first alarm signal or the second alarm signal, it will sound an alarm to form a linkage with the surrounding safety cones, thereby improving the early warning effect.

[0064] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
