[0035] Reference below Figures 1 to 7 A path sign with a monitoring function according to an embodiment of the utility model is described.
[0036] like Figures 1 to 7 As shown, the path sign with monitoring function according to an embodiment of the utility model includes a shell 100 and a monitoring unit 200 .
[0037] The housing 100 may be in a disc shape or other suitable shapes. A transparent cover 101 is provided at the top of the housing 100. An inner cavity is formed in the housing 100. The monitoring unit 200 is arranged in the inner cavity of the housing 100. The transparent cover 101 may be detachably connected to the housing 100, for example, by fastener connection, threaded connection or snap connection, so as to facilitate cleaning, maintenance or replacement of the components in the housing 100. A reminder board 500 may be provided in the housing 100. For example, the reminder board 500 may be installed on the top of the monitoring unit 200. When the path sign with monitoring function is used for the cable pipe, the words "there are cables below, digging is strictly prohibited" may be set on the reminder board 500 to remind people that there is a cable pipe nearby. The transparent cover 101 is transparent, which is convenient for people to observe the reminder board 500 and convenient for the visual sensor module 201 to take pictures. The transparent cover 101 can be made of transparent acrylic material, which has high impact strength, bending strength and toughness, and can effectively avoid being crushed by uncertain factors such as large vehicles in the external environment. It also has the advantages of light specific gravity, corrosion resistance, aging resistance and beautiful appearance. Of course, the transparent cover 101 can also be made of other suitable transparent materials, such as tempered glass, which will not be repeated here.
[0038] The monitoring unit 200 is arranged in the inner cavity of the housing 100. The monitoring unit 200 includes a plurality of visual sensor modules 201. The number of the visual sensor modules 201 may be two, three, four, five or other numbers. For example, the number of the visual sensor modules 201 may be four. The plurality of visual sensor modules 201 may be arranged along the circumference of the housing 100. Of course, the arrangement may also be performed in other ways. The shooting direction of at least some of the visual sensor modules 201 may be tilted outward in an upward direction. Specifically, the shooting direction of all the visual sensor modules 201 may be tilted outward in an upward direction, or the shooting direction of some of the visual sensor modules 201 may be tilted outward in an upward direction, while the shooting direction of other visual sensor modules 201 may be in other directions, such as vertically upward. The visual sensor module 201 may be a CCD sensor, a CMOS sensor or other suitable visual sensor module 201. The visual sensor module 201 is a common visual detection device, and its structure and working principle will not be described in detail here. The visual sensor module 201 may be loaded with a vibration source library. The visual sensor module 201 compares the captured vibration process with the vibration source library and can determine the cause of the vibration in time to improve the efficiency and accuracy of intelligent recognition.
[0039] The monitoring unit 200 may also include other components, for example, it may also include a vibration sensing module, a control module, a positioning module and a communication module. The visual sensor module 201, the vibration sensing module, the positioning module and the communication module are all connected to the control module. The vibration sensing module is used to detect the vibration of the path sign with the monitoring function. The vibration sensing module can be various vibration sensors. The positioning module is used to locate the path sign with the monitoring function. The positioning module can be a GPS Beidou dual-mode module, so that the advantages and satellite resources of the two satellite positioning systems of GPS and Beidou can be fully utilized, and the accuracy and reliability are stronger to meet the needs of various application scenarios. Of course, the positioning module can also be a separate GPS module or Beidou module. The communication module can be a 4G communication module, a 5G communication module or other suitable communication modules. The communication module is used to transmit the relevant video, image, alarm information and positioning information to the background. The control module is used to coordinate the operation of the visual sensor module 201, the vibration sensing module, the positioning module and the communication module, and can process and transmit the data at the same time. The positioning module can facilitate the staff to find the location of the path sign with the monitoring function in time after the path sign with the monitoring function is stolen and moved. The visual sensor module 201, the vibration sensing module, the control module, the positioning module and the communication module are all relatively common devices in various industries, and their structures and working principles are not described in detail here.
[0040] When the path sign with a monitoring function vibrates, for example, when the path sign with a monitoring function is damaged or stolen, the vibration sensing module senses and sends an alarm message to the control module, and the control module controls the communication module to send the alarm message to the background. At the same time, multiple visual sensor modules 201 can cooperate to shoot the process and personnel of the path sign with a monitoring function being damaged or stolen. After the visual sensor module 201 processes the captured video or image, the control module controls the communication module to transmit the video and image to the background, and the staff can process it in time. Moreover, the staff can understand the process and personnel of the path sign with a monitoring function being damaged or stolen through the video or image, which is convenient for the staff to grasp the situation on the scene and judge whether it is a false alarm. In addition, the shooting direction of at least part of the visual sensor module 201 is tilted outward in the upward direction, so even if the person who damages or steals the path sign with a monitoring function deliberately hides on the outside of the path sign with a monitoring function, it can be clearly photographed, which is more practical.
[0041] It should be noted that the visual sensor module 201 can have the function of expanding and replacing the vibration source library, can replace different vibration source libraries for different environments, and support the increase and decrease of vibration source data, thereby further improving the efficiency and accuracy of intelligent recognition. In addition, the entire monitoring unit 200 can adopt a low-power design, including a low-power control module, a vibration sensing module, a visual sensor module 201, a positioning module and a communication module, thereby reducing power consumption and increasing service life.
[0042] It is understandable that the control module can have a self-learning function. When the self-learning function is activated, the control module does not actively report the alarm information. The vibration amplitude and frequency of the on-site environment are obtained as the initial state within a certain period of time. After that, the control module turns off the self-learning function and enters the working state. When the path sign with a monitoring function is damaged or stolen, the vibration sensing module detects that the vibration amplitude and frequency generated by the external environment are higher than the initial state, and the vibration sensing module generates new alarm information. The visual sensor module 201 shoots video and images, and the control module sends the video, image and alarm information to the background in a timely manner through the communication module. In addition, the control module and the communication module may not be set on the path sign with a monitoring function, but may be set at other locations for remote control and signal transmission.
[0043] In some embodiments of the present invention, Figure 1 , Figure 5 and Figure 7 As shown, the transparent cover 101 is formed with a refractive surface 102 corresponding to the visual sensor module 201, and the visual sensor module 201 faces the refractive surface 102. For example, the refractive surface 102 can be located on the bottom surface or the top surface of the transparent cover 101, and the refractive surface 102 can refract the light, thereby correcting and improving the shooting range of the visual sensor module 201, so that it is more convenient for the visual sensor module 201 to explore the current environment, and the practicality is better.
[0044] In some embodiments of the present invention, Figure 1 , Figure 5 and Figure 7 As shown, the bottom surface of the transparent cover 101 is provided with a recess 103 corresponding to the visual sensor module 201. The recess 103 may be arc-shaped or wedge-shaped. The visual sensor module 201 is received in the recess 103, and the surface of the recess 103 forms a refractive surface 102. In this way, the recess 103 can not only be used to receive the visual sensor module 201, thereby making the protection effect of the visual sensor module 201 better, but also the surface of the recess 103 forms a refractive surface 102. The surface of the recess 103 is similar to the surface of a concave mirror, which can refract light, and has dual uses in one body, and the design is ingenious.
[0045] It should be noted that the top surface of the transparent cover 101 may also be provided with a curved surface. For example, the top surface close to the visual sensor module 201 may be provided with a curved surface. The curved surface forms a refractive surface 102, which can also refract light and is easy to process. If the transparent cover 101 is provided with both a recess 103 and a curved surface, the refraction effect of light can be further improved, thereby further correcting and improving the shooting range of the visual sensor module 201.
[0046] In some embodiments of the present invention, Figures 2 to 4 As shown, multiple visual sensor modules 201 are arranged along the circumference of the housing 100. For example, there may be four visual sensor modules 201, and the four visual sensor modules 201 are evenly arranged along the circumference of the housing 100. Such an arrangement enables the visual sensor module 201 to have a wider shooting range, more comprehensive shooting, and reduce missed shooting.
[0047] It should be noted that in some other embodiments of the present invention, the visual sensor module 201 may also be arranged in other ways.
[0048] In some embodiments of the present invention, Figure 2 , Figure 6 and Figure 7 As shown, a first receiving groove 104 is provided in the housing 100, and an elastic buffer pad 300 is provided in the first receiving groove 104, and the monitoring unit 200 can be installed on the top of the elastic buffer pad 300. The elastic buffer pad 300 can be made of elastic soft rubber such as elastic rubber or elastic silicone, and the elastic buffer pad 300 has a good performance of reducing impact. When the path sign with a monitoring function is crushed and stepped on, it can play a buffering role to protect the monitoring unit 200. In addition, the elastic buffer pad 300 can also play a certain sealing role, can prevent dust and water, and reduce the pollution and damage of the components below the elastic buffer pad 300.
[0049] In some embodiments of the present invention, Figure 2 , Figure 5 and Figure 7As shown, a first annular slot 105 is formed between the outer side wall of the elastic buffer pad 300 and the inner side wall of the first receiving groove 104, and a first snap ring 106 is provided on the peripheral side of the transparent cover 101, and the first snap ring 106 is inserted in the first annular slot 105. When the transparent cover 101 needs to be installed, the first snap ring 106 on the transparent cover 101 is inserted in the first annular slot 105, and then the transparent cover 101 is fastened by a fastener. The assembly and positioning of the transparent cover 101 is very convenient, and the cooperation between the first snap ring 106 and the first annular slot 105 can also improve the installation stability of the transparent cover 101. In addition, the first snap ring 106 also has a sealing effect, which can reduce the entry of external water and dust into the first receiving groove 104.
[0050] In some embodiments of the present invention, Figures 2 to 5 as well as Figure 7 As shown, the top of the elastic buffer pad 300 is provided with a second receiving groove 301, the monitoring unit 200 is installed in the second receiving groove 301, the edge of the bottom surface of the second receiving groove 301 is provided with a second annular slot 302, and the bottom surface of the transparent cover 101 is provided with a second snap ring 107, and the second snap ring 107 is inserted in the second annular slot 302. The monitoring unit 200 is installed in the second receiving groove 301, and the installation is more convenient and stable. The second annular slot 302 can be arranged roughly along the circumference of the housing 100, and the second snap ring 107 can be arranged roughly along the circumference of the transparent cover 101. Through the cooperation of the second snap ring 107 and the second annular slot 302, the installation stability of the transparent cover 101 can be further improved. In addition, the second snap ring 107 also has a sealing effect, which can reduce the external water and dust from entering the second receiving groove 301 and affecting the monitoring unit 200, and the practicality is better.
[0051] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, the inner side wall of the first receiving groove 104 is formed with a plurality of first slots 108, the elastic buffer pad 300 is correspondingly provided with a plurality of first protrusions 303, the first protrusions 303 are clamped in the first slots 108, the inner side wall of the second receiving groove 301 is formed with a plurality of second slots 304, the monitoring unit 200 is correspondingly provided with a plurality of second protrusions 202, the second protrusions 202 are clamped in the second slots 304. For example, the first slots 108 and the first protrusions 303 can be provided with four and arranged along the circumference of the housing 100, and the second slots 304 and the second protrusions 202 can be provided with four and arranged along the circumference of the housing 100. In this embodiment, such a configuration not only makes it more convenient to assemble and position the elastic buffer pad 300 and the monitoring unit 200, but also can prevent the elastic buffer pad 300 and the monitoring unit 200 from rotating at will, so that the elastic buffer pad 300 and the monitoring unit 200 are installed more firmly.
[0052] In some embodiments of the present invention, Figures 2 to 4 as well as Figure 7 As shown, the monitoring unit 200 is provided with a mounting groove 203, a solar panel 400 is installed in the mounting groove 203, a battery 401 is provided in the housing 100 below the elastic buffer pad 300, the solar panel 400 is connected to the battery 401, and the battery 401 is used to supply power to the monitoring unit 200. For example, the mounting groove 203 can be penetrated from top to bottom, the solar panel 400 is embedded in the mounting groove 203, the solar panel 400 is close to the transparent cover 101, the battery 401 can be a large-capacity lithium battery, the battery 401 is used to store electricity, the battery 401 is located below the elastic buffer pad 300, and can reduce the situation where the battery 401 is damaged, the solar panel 400 is connected to the battery 401, and the battery 401 is connected to the monitoring unit 200. The solar panel 400 can convert light energy into electrical energy and transmit the electrical energy to the battery 401 for storage, and the battery 401 supplies power to the monitoring unit 200 to achieve stable energy supply.
[0053] It should be noted that the monitoring unit 200 may also be powered by an external power source.
[0054] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 6 As shown, the outer wall of the housing 100 is provided with a plurality of circumferentially arranged limiting grooves 109. When the path sign with monitoring function is buried underground, soil can be embedded in the limiting grooves 109, thereby making the path sign with monitoring function more firmly installed.
[0055] In some embodiments of the present invention, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the housing 100 also includes a base 110, and the first receiving groove 104 is arranged in the base 110. The base 110 can be cast from aluminum. The top of the base 110 is installed with an annular pressing ring 111 through a fastener, and the annular pressing ring 111 abuts against the edge of the top of the transparent cover 101. The transparent cover 101 is placed in the first receiving groove 104, and then the annular pressing ring 111 is pressed on the edge of the top of the transparent cover 101, and the annular pressing ring 111 is fixed to the base 110 through a fastener, which is convenient for disassembly, saving time and effort. In addition, the annular pressing ring 111 can also prevent external water and dust from entering the first receiving groove 104 through the gap between the transparent cover 101 and the base 110, and the sealing effect is better.
[0056] In some embodiments of the present invention, Figures 2 to 4 as well as Figure 7As shown, the path sign with monitoring function also includes a warning light 204. The warning light 204 can be arranged on the monitoring unit 200. The warning light 204 can be connected to the control module. The bottom surface of the transparent cover 101 can be provided with a receiving cavity, and the light-emitting position of the warning light 204 is located in the receiving cavity. The warning light 204 can be lit at night to display the reminder slogan on the reminder board 500. The surface of the receiving cavity can be an arc-shaped surface, which can then cooperate with the curved surface at the top of the transparent cover 101 to refract the light, so that the light emitted by the warning light 204 has a wider irradiation range and is easier to be found. When the path sign with monitoring function vibrates, the corresponding warning light 204 flashes to remind the staff, so that the staff can quickly find the corresponding path sign with monitoring function.
[0057] It should be noted that during actual use, multiple path signs with monitoring functions can be used in conjunction. Specifically, the signal of the vibration sensing module of the path sign with monitoring function that is vibrating can be transmitted to the control module of the path sign with monitoring function at other locations. The specific position of the path sign with monitoring function that is vibrating can be calculated by the time and amplitude of the signal transmission, so that the staff can determine the position of the path sign with monitoring function that is vibrating more quickly and accurately, which is more practical.
[0058] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
