[0036] Referring to Figures 1 to 3 The present application provides a prefabricated pavement system to better achieve intelligent traffic management, the main components include prefabricated slab 100, monitoring device 200 and host computer 300, wherein the upper surface of the prefabricated slab 100 is provided with a plurality of blind holes 110, it can be understood that since the prefabricated slab 100 is used as pavement, the side of the prefabricated slab 100 for pedestrians and vehicles to walk on is the upper surface. The monitoring device 200 is installed in the corresponding blind hole 110, the monitoring device 200 is used to monitor pedestrians and vehicles on the prefabricated slab 100, and can monitor the state of the prefabricated slab 100 itself, such as the temperature and humidity of the surface, etc., which depends on which kind of monitoring device the monitoring device 200 itself belongs to. The host computer 300 is in communication connection with the monitoring device 200, and the monitoring device 200 can transmit its monitoring data to the host computer 300.

[0037] Specifically, in the above embodiment, the monitoring device 200 can be a variety of sensors, such as a pressure sensor for monitoring pressure, which can determine whether motor vehicles, non-motor vehicles or pedestrians pass on the section of pavement, so as to determine whether pedestrians or non-motor vehicles walk on the motor vehicle lane, or whether motor vehicles walk on the non-motor vehicle lane; it can also be a time-related sensor, such as the number of motor vehicles, non-motor vehicles and pedestrians passing within 10 minutes, to determine the red and green light duration of the traffic light, etc., it can also be an acceleration sensor, a temperature sensor, a humidity sensor, etc. As long as it can collect information of pedestrians and vehicles on the pavement, and reflect the road itself situation, such as the road traffic quality after rain and snow, which is conducive to intelligent traffic management, it can be applied to the prefabricated pavement system of the present application as the monitoring device 200.

[0038] Similarly, in the above embodiment, the host computer 300 can be a PC computer, or a special device for receiving monitoring data of the monitoring device 200, when the monitoring device 200 is a picture collecting device, the host computer 300 can also simply monitor the picture device to monitor the real-time picture of the section of pavement. Since the device is various and widely used, it will not be repeated here.

[0039] The prefabricated pavement system has the prefabricated plate 100 as a main structure, the upper surface of the prefabricated plate 100 is provided with a plurality of blind holes 110, the monitoring device 200 is installed in the plurality of blind holes 110, the monitoring device 200 can monitor pedestrians and vehicles and generate relevant monitoring data, the upper computer 300 is in communication connection with the monitoring device 200, and the monitoring device 200 can transmit the monitoring data to the upper computer 300. The prefabricated pavement system provided in the application can better monitor the pedestrians and vehicles on the road section, provide reliable evidence for subsequent traffic planning of the road section according to the collected relevant data, and is beneficial to the planning and design of the traffic of the road section.

[0040] It can be understood that the monitoring device 200 can have a plurality of functional signal acquisition devices, such as an “acceleration + temperature sensor”, an “acceleration + humidity sensor”, a “temperature + humidity sensor” and the like.

[0041] Specifically, for example, the monitoring device 200 is a pressure No. 1 sensor, and the proportion of non-motor vehicles to motor vehicles passing through the road section within 1 hour is 10 percentage points higher than that on other roads, which indicates that the situation of pedestrians riding non-motor vehicles on the motor vehicle lane is more common, so the road section can remind the driving problems of non-motor vehicles through traffic police supervision or large-screen text publicity, so as to reduce the probability of traffic accidents between non-motor vehicles and motor vehicles. For another example, the monitoring device 200 is a time + light No. 2 sensor, when a vehicle or a pedestrian passes through the No. 2 sensor, the No. 2 sensor will generate a light signal due to the blocking of light, and the No. 2 sensor will generate relevant data of 1 vehicle or 1 pedestrian, and within 1 minute, 25 vehicles or 10 pedestrians pass through, which indicates that the density of vehicles or pedestrians passing through the road section is large, which indicates that there are more residential areas nearby. According to the data, the display time of the traffic signal lights before and after the road section can be adjusted to reduce the probability of large traffic congestion on the road section to block the crossroads or avoid the occurrence of safety accidents between pedestrians and vehicles.

[0042] Referring to Figure 1 In one embodiment, the prefabricated plate 100 is internally provided with a pipeline 120, the plurality of blind holes 110 are in communication with the pipeline 120, the upper computer 300 is in wired connection with the monitoring device 200 through a communication cable, the communication cable is located in the pipeline 120, and at least one end of the pipeline 120 is in communication with the outside of the prefabricated plate 100, so that the communication cable can be stretched out. Compared with wireless signals which are easily disturbed by the environment, the wired connection of the monitoring device 200 and the upper computer 300 can make the signal transmission more stable and reliable.

[0043] Preferably, when a plurality of prefabricated plates 100 are used on a road surface, the pipes 120 on the plurality of prefabricated plates 100 can be connected, so that the communication cable in the prefabricated plate 100 in the middle region can extend out through the pipes 120 in the surrounding prefabricated plates 100, thereby being in communication connection with the host computer 300.

[0044] Similarly, in areas with good signal transmission, wireless connection can be used, that is, the monitoring device 200 transmits the monitoring data to the host computer 300 through wireless transmission.

[0045] Referring to Figure 2 and Figure 3 In one embodiment, the monitoring device 200 includes a signal interaction module 210, a sensing module 220, and a wired output end, which are in communication connection, the wired output end is in communication connection with the communication cable, the sensing module 220 is used for monitoring pedestrians and vehicles and collecting monitoring data, and the signal interaction module 210 and the wired output end are used for transmitting the monitoring data to the host computer 300. When the host computer 300 is close to the monitoring device 200, wireless transmission of data can greatly reduce the use cost compared with wired connection.

[0046] Referring to Figure 3 In one embodiment, a matching cover component 130 is further included, and the outer circumferential surface of the matching cover component 130 is adapted to the inner wall of the blind hole 110, such as both being circular. The matching cover component 130 is used for plugging the blind hole 110, and can prevent foreign matters such as dust and rainwater from the outside from entering the blind hole 110 to affect the normal working state of the monitoring device 200, and can also prevent the loss of the monitoring device 200.

[0047] Specifically, the matching cover component 130 can be composed of an elastic material, such as rubber. In the normal state, the diameter of the matching cover component 130 is slightly larger than that of the blind hole 110, so that after being inserted into the blind hole 110, the matching cover component 130 is prevented from being taken out of the blind hole 110 by extrusion force.

[0048] Referring to Figure 3 A plurality of small blind holes are arranged on the upper surface of the matching cover component 130, so as to facilitate the taking out of the matching cover component 130 from the blind hole 110, and facilitate the replacement of the monitoring device 200. It can be understood that according to different tools, the small blind holes can be threaded holes or triangular holes.

[0049] Referring to Figure 1In one of the embodiments, the prefabricated slab 100 is provided with a plurality of connecting holes 140, which are used for the fixed connection between the plurality of prefabricated slabs 100. It can be understood that the prefabricated slab 100 is made of multiple pieces and needs to be spliced when installed on the roadbed. The connecting holes 140 can be placed with connecting members such as reinforcing bars to facilitate the fixed connection between the adjacent prefabricated slabs 100. At the same time, the connecting holes 140 can prevent the prefabricated slabs 100 from being pressed and deformed due to thermal expansion and contraction, thereby affecting the service life of the pavement.

[0050] Referring to Figure 4 The application also provides a prefabricated slab mold 400, which comprises a plurality of side walls 410 and a bottom wall. The plurality of side walls 410 and the bottom wall surround a space 420 with an opening facing upward, which is used for forming the main body of the prefabricated slab 100. The side wall 410 is provided with a plurality of protrusions 430 extending inward, which are used for forming the connecting holes 140. The opening is provided with a suspension 440. The space 420 is provided with a pipeline mold frame 450 and a monitoring device mold frame 460. The pipeline mold frame 450 is used for forming the pipeline 120, and the monitoring device mold frame 460 is used for forming the monitoring device 200. One end of the monitoring device mold frame 460 is connected with the pipeline mold frame 450, and the other end is connected with the suspension 440, so that the pipeline mold frame 450 is suspended, and the pipeline 120 is between the prefabricated slabs 100, thereby protecting the communication cable. The prefabricated slab mold 400 provided by the application can produce the prefabricated slab 100 in the prefabricated pavement system.

[0051] It can be understood that the intelligent device 200 and the upper computer 300 can be purchased in the market as prior art, and will not be described here.

[0052] Preferably, in one of the embodiments, the two oppositely arranged side walls 410 are provided with guide rails 470 above. The suspension 440 can reciprocate relative to the guide rails 470. The movement of the suspension 440 means that the distance between the blind holes 110 can be adjusted. For example, if the prefabricated slab 100 is used for a traffic artery, the distance between the plurality of blind holes 110 can be relatively close. Of course, it can also be relatively far, depending on the specific use mode. Therefore, the adjustable suspension 440 is conducive to the production of a variety of prefabricated slabs 100, without the need to use a variety of prefabricated slab molds 400, thereby effectively reducing the processing cost.

[0053] Specifically, referring to Figure 4 For the straight prefabricated slab 100, two parallel guide rails 470 are provided above the oppositely arranged side walls 410. The suspension 440 and the guide rail 470 are rotatably connected through a hub. It can be understood that the suspension 440 should be above the space 420 to prevent the suspension 440 from acting as a mold during the forming of the prefabricated slab 100.

[0054] In other embodiments, a slider can be provided on the guide rail 470, and the suspension 440 is fixedly connected to the slider to realize the reciprocating movement of the suspension 440 on the guide rail 470.

[0055] When the prefabricated slab 100 produced is a prefabricated slab 100 at a crossroad, at this time, there is a need for the vehicle to turn left and right, and the blind hole 110 can need to be arranged in a 90° circular arrangement according to the driving path of the vehicle. At this time, the guide rail 470 can be arranged above the space 420 and is not limited to above the side wall 410. The suspension 440 can move according to the circular guide rail 470 at one end, and can rotate around a point without displacement at the other end.

[0056] Preferably, in one of the embodiments, the monitoring device mold frame 460 is slidingly connected to the suspension 440, and the length of the pipe mold frame 450 is adjustable, so that the distance between the blind holes 110 can be adjusted. Similarly, the adjustable means that a set of prefabricated slab molds 400 can produce prefabricated slabs 100 suitable for various traffic sections, thereby reducing the processing cost. In the vertical direction, the length of the monitoring device mold frame 460 is adjustable. It can be understood that the sizes and lengths of the monitoring devices 200 are different, and the adjustable length of the monitoring device mold frame 460 can change the depth of the blind hole 110 to accommodate more types of monitoring devices 200 or place multiple monitoring devices 200. In the vertical direction, the length of the pipe mold frame 450 can also be adjusted to determine the position of the communication cable in the prefabricated slab 100.

[0057] In one of the embodiments, the side wall 410 is provided with a plurality of reinforcing ribs 411. It can be easily understood that the reinforcing ribs 411 can enhance the strength of the side wall 410.

[0058] The application also provides a preparation method of a prefabricated pavement system, comprising the following steps:

[0059] Using the prefabricated slab mold 400 in any of the above embodiments to produce the prefabricated slab 100;

[0060] On-site installation of the prefabricated slab 100;

[0061] Installation of the monitoring device 200;

[0062] Communication connection between the monitoring device 200 and the upper computer 300.

[0063] According to the above preparation method, the prefabricated pavement system can be produced and installed, and finally put into use. The data collection personnel can collect the data monitored by the monitoring device 200. The data analysis personnel can manually analyze or computer analyze the monitoring data, thereby generating data with certain value. The policy makers can formulate relevant traffic policies according to the data, so as to improve the scientificity and effectiveness of traffic management on the section of pavement, thereby making the traffic management more intelligent and more conducive to the travel of pedestrians and vehicles, and improving the happiness of citizens.

[0064] Specifically, in the step of producing the prefabricated slab 100 using the prefabricated slab mold 400 in any of the above embodiments, the traffic flow is preliminarily judged according to the specific position where the prefabricated slab 100 to be produced is placed, so as to adjust the suspension 440 to a suitable position, adjust the pipe mold frame 450 to a suitable length, and adjust the monitoring device mold frame 460 to a suitable depth, so as to produce the prefabricated slab 100 meeting the standards. The on-site installation of the prefabricated slab 100 belongs to civil engineering, which is not described here. After the monitoring device 200 is installed, the matching cover part 130 can be used to plug the blind hole 110, so as to protect the monitoring device 200.

[0065] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0066] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
